Fig. 1 illustrates a perspective view of a solar cell typesetting device in an embodiment of the invention. Fig. 2 illustrates a top view of a solar cell typesetting device in the embodiment of the invention. As shown in fig. 1 and 2, the solar cell typesetting equipment comprises at least one feeding area C, at least one transfer area D, and a typesetting station E. Each loading area C includes a plurality of loading stations C1 distributed along the conveying direction of the battery pieces a, and each transfer area D has a plurality of transfer stations D1 corresponding to the loading stations C1.

Specifically, as shown in fig. 1 and 2, a plurality of transfer stations D1 are disposed in parallel with a plurality of loading stations C1, and are also distributed along the conveying direction of the battery pieces a.

As shown in fig. 1 and fig. 2, the solar cell typesetting apparatus includes: at least one set of flip structures 100, at least one typesetting mechanism 200, and a hot press mechanism 300. Each set of flipper structures 100 includes a plurality of flippers 110 corresponding to the transfer station D1. Each turnover mechanism 110 is arranged between the corresponding feeding station C1 and the transferring station D1, and is used for turning the battery piece a from the corresponding feeding station C1 to the transferring station D1, and the back contact surface of the battery piece a at the transferring station D1 faces the direction of the plane of the back plate B. In practical application, the back plate B is located below the battery piece a, and the back contact surface of the battery piece a is turned upside down.

As shown in fig. 1 and 2, at least one typesetting mechanism 200 is disposed between the corresponding transfer area D and the typesetting station E, so as to transfer the plurality of battery pieces a from the corresponding transfer area D to the corresponding typesetting position of the backboard B when the plurality of battery pieces a are located in the transfer area D and the backboard B is located in the typesetting station E.

As shown in fig. 1 and fig. 2, the hot pressing mechanism 300 is disposed at the typesetting station E, and is configured to hot press the plurality of battery pieces a at the corresponding typesetting positions of the back plate B.

As shown in fig. 2, the solar cell typesetting apparatus may further include a first conveying mechanism 400, where the first conveying mechanism 400 is configured to convey the solar cells a to a plurality of loading stations C1. The plurality of loading stations C1 are distributed along the conveying direction of the first conveying mechanism 400. Specifically, the first conveying mechanism 400 may be a conveyor belt. The battery piece a is placed on the conveyor belt and conveyed to the feeding station C1 by the conveyor belt. Since the back contact surface of the battery piece a is already printed with the plurality of conductive contacts when the first transfer mechanism 400 transfers the battery piece a, the back contact surface of the battery piece a transferred by the first transfer mechanism 400 may be away from the transfer surface of the first transfer mechanism 400 as shown in fig. 1 and 2. Specifically, as shown in fig. 2, the battery piece a is placed on the conveying surface of the first conveying mechanism 400, and the back contact surface of the battery piece a faces away from the conveying surface of the first conveying mechanism 400. In practical application, the back contact surface of the battery piece A faces upwards.

As shown in fig. 2, since the back plate B corresponds to a plurality of battery pieces a, two first conveying mechanisms 400 may be provided, and the two first conveying mechanisms 400 are respectively located at two sides of the composition station E, so as to provide a plurality of battery pieces a for the composition station E at the same time. Of course, a plurality of loading stations C1 may be disposed on the first conveying mechanism 400, so as to further increase the speed of providing the battery pieces a for the typesetting station E.

As shown in fig. 2, the solar cell typesetting apparatus may further include a second conveying mechanism 500, where the second conveying mechanism 500 is configured to convey the back sheet B to the typesetting station E. The second conveyance mechanism 500 may be a conveyor belt. The backboard B is placed on the conveyor belt and conveyed to the typesetting station E by the conveyor belt. In practical applications, since the battery pieces a need to be mounted on the mounting surface of the backboard B, the mounting surface of the backboard B deviates from the conveying surface of the second conveying mechanism 500 in the process of conveying the backboard B, that is, the mounting surface of the backboard B faces upward.

As shown in fig. 2, the number of the turnover mechanism 110 and the typesetting mechanism 200 may be set as desired. Each solar cell typesetting device can be provided with one turnover mechanism 110 and one typesetting mechanism 200, or a plurality of turnover mechanisms can be provided. The number of the turnover mechanisms 110 and the number of the typesetting mechanisms 200 may or may not be one-to-one, which is not limited.

In practical application, as shown in fig. 2, when a back contact solar cell module is produced, the first conveying mechanism 400 provides a plurality of cell pieces a to the loading area C, and the second conveying mechanism 500 provides the back sheet B to the typesetting station E. The plurality of battery pieces a in the feeding region C are distributed in the conveying direction of the first conveying mechanism 400. The turnover structure 100 first turns over the plurality of battery pieces a in the loading area C to the transfer area D at the same time, and the back contact surface of the battery piece a at the transfer station D1 faces downward. Then, the layout mechanism 200 transfers the plurality of battery pieces a in the transfer area D to the corresponding layout positions of the back plate B. Finally, the hot-pressing mechanism 300 hot-presses the plurality of battery pieces a at the corresponding typesetting positions of the back plate B.

As shown in fig. 1 and 2, each turnover mechanism 110 is used to turn the battery sheet a from the corresponding loading station C1 to the corresponding transfer station D1. Generally, when the battery piece a is conveyed by the conveying mechanism, the back contact surface of the battery piece a is preferably upward, i.e. away from the conveying surface of the conveying mechanism, so as to prevent the conductive material on the back contact surface of the battery piece a from being damaged after the conveying surface of the conveying mechanism is contacted with the back contact surface of the battery piece a. When the back contact solar cell module is produced, the turnover mechanism 110 first turns over the plurality of the conveyed battery pieces a from the corresponding loading stations C1 to the transfer station D1, so that the back contact surfaces of the battery pieces a at the transfer station D1 face the direction of the plane of the back plate B. Then, the typesetting mechanism 200 transfers the battery piece a from the corresponding transfer station D1 to the corresponding typesetting position of the back panel B. Therefore, when the cell A is installed on the backboard B, the typesetting is firstly carried out through the typesetting mechanism 200, so that the offset of the back contact cell A and the backboard B in the alignment can be reduced, the automation of the back contact solar cell module is realized, the production efficiency of the back contact solar cell module is improved, and the production cost is reduced.

In addition, as shown in fig. 1 and 2, each of the loading regions C includes a plurality of loading stations C1 distributed along the transfer direction of the battery pieces a, each of the transfer regions D has a plurality of transfer stations D1 corresponding to the loading stations C1, and each of the group of turnover structures 100 includes a plurality of turnover mechanisms 110 corresponding to the transfer stations D1. Based on this, the turnover structure 100 can turn over a plurality of battery pieces a at the same time, and typeset the plurality of battery pieces a at the corresponding typesetting positions of the backboard B at the same time through the typesetting mechanism 200, so as to improve the typesetting efficiency.

Furthermore, as shown in fig. 1 and fig. 2, the solar cell module manufacturing apparatus further includes a hot pressing mechanism 300 disposed at the typesetting station E, wherein the hot pressing mechanism 300 is configured to hot press the plurality of battery pieces a at the corresponding typesetting positions of the back sheet B. After the typesetting mechanism 200 typesets the plurality of battery pieces a at the corresponding typesetting positions of the back plate B, the hot-pressing mechanism 300 hot-presses the plurality of battery pieces a on the back plate B. In the process of hot-pressing the battery piece a by the hot-pressing mechanism 300, the typesetting mechanism 200 can take off a batch of battery pieces a, so that the typesetting process and the hot-pressing process are separately performed, the production rhythm is accelerated, and the typesetting efficiency is further improved.

As a possible implementation manner, the solar cell module manufacturing apparatus may further include: the device comprises a plurality of first image collectors corresponding to the transfer stations, at least one second image collector and a controller which is respectively communicated with the first image collectors, the second image collectors and the typesetting mechanism.

As shown in fig. 2, each first image collector 600 is configured to collect an image of the back contact surface of the cell a when the cell a is located at the corresponding transfer station D1. Specifically, the plurality of first image collectors 600 are arranged in parallel with the plurality of transfer stations D1, that is, the plurality of first image collectors 600 are also distributed along the conveying direction of the battery piece a. The first image collector 600 may be an industrial camera, but is not limited thereto. Each second image collector 700 is configured to collect the layout image at the layout position of the backboard B when the backboard B is located at the layout station E. The second image collector 700 may be an industrial camera, but is not limited thereto. The controller controls the typesetting mechanism 200 to transfer the plurality of battery pieces A to the corresponding typesetting positions of the backboard B according to the images of the back contact surfaces of the battery pieces A and the typesetting images.

Specifically, as shown in fig. 2, when the back-contact solar cell module is produced, the turnover mechanism 110 turns over the back contact surface of the cell a at the transfer station D1, so that after the back contact surface of the cell a faces downward, the first image collector 600 is controlled to collect the image of the back contact surface of the cell a at the corresponding transfer station D1, and the image of the back contact surface of the cell a is sent to the controller; controlling the second image collector 700 to collect the typesetting image of the backboard B and sending the typesetting image of the backboard B to the controller; the controller controls the typesetting mechanism 200 to typeset the back contact surface of the battery piece A at the corresponding typesetting position of the backboard B according to the image of the back contact surface of the battery piece A and the typesetting image of the backboard B.

As shown in fig. 2, after the turnover mechanism 110 places the cell a at the corresponding transfer station D1, the corresponding first image collector 600 collects an image of the back contact surface of the cell a when the cell a is at the corresponding transfer station D1. When the backboard B is located at the typesetting station E, the second image collector 700 collects the typesetting image of the typesetting position of the backboard B. The controller controls the typesetting mechanism 200 to typeset the plurality of battery pieces A at the corresponding typesetting positions of the backboard B according to the images of the back contact surfaces of the battery pieces A and the typesetting images. Based on this, after conveying battery piece A and backplate B, the controller controls typesetting mechanism 200 according to the image of the battery piece A back contact surface and the typesetting image of the typesetting position to typeset a plurality of battery pieces A at the corresponding typesetting position of backplate B, even if battery piece A and backplate B shift in the conveying process, the position of backplate B and battery piece A need not to be accurate during conveying, the requirement on the device for conveying battery piece A and backplate B is low, and make battery piece A and backplate B align accurately, the yield of back contact solar module has greatly been improved, and have stronger adaptability and flexibility to production environment and production condition, be adapted to various module types.

In an alternative, the at least one first image collector may be provided at the transfer station. The first image collector and the transfer station are arranged in a one-to-one correspondence mode. The first image collector can collect images of the back contact surface of the battery piece of the corresponding rotating station.

In an alternative, fig. 3 illustrates a schematic diagram of a typesetting mechanism in an embodiment of the invention. As shown in FIG. 3, the at least one second image collector 700 may be disposed at one end of the corresponding layout mechanism 200. The type setter can drive the second image collector 700 to move, when the second image collector 700 is close to the corresponding type setting position of the battery piece A, the second image collector 700 can collect the image at the corresponding type setting position, so that the second image collector 700 can conveniently and accurately collect different type setting position images, and the situation that the position of the battery piece A mounted on the backboard B is deviated due to the fact that the image collected by the second image collector 700 is a convex projection area if the middle area of the backboard B is convex when the second image collector 700 is arranged above the backboard B is avoided.

As a possible implementation manner, as shown in fig. 1 and fig. 2, the hot pressing mechanism 300 may be a hot pressing horizontal mechanism, and the hot pressing horizontal mechanism has a plurality of hot pressing stations corresponding to the typesetting positions. Based on this, the hot pressing horizontal mechanism can hot pressing the battery piece A on a plurality of composing positions corresponding to the hot pressing station simultaneously.

Specifically, as shown in fig. 1, the hot pressing mechanism 300 may include a hot pressing board, a hot pressing driving mechanism for driving the hot pressing board to perform hot pressing on the battery piece a, and a moving driving device for driving the hot pressing board to move. The plurality of hot pressing stations are arranged on one side of the hot pressing plate facing the back plate B corresponding to the plurality of typesetting positions. Generally, the hot pressing plate is located above the back plate B, and thus, the hot pressing station is located below the hot pressing plate.

As shown in fig. 1, the hot press plate may extend along one side edge of the back plate B, and the moving driving device may include a hot press moving device and a hot press lifting device. The hot pressing mobile device is used for driving the hot pressing plate to move, the moving direction of the hot pressing plate is perpendicular to the extending direction of the hot pressing plate, so that the hot pressing plate can be sequentially located above each part of the backboard B, the battery piece A on each part of the backboard B is hot pressed, and when the hot pressing is not needed, the hot pressing plate can be moved to the side face of the backboard B, and the hot pressing plate is prevented from influencing the work of the typesetting mechanism 200. The hot-pressing lifting device is used for driving the hot-pressing plate to lift, so that the hot-pressing plate is contacted with or separated from the battery piece A.

In one example, a plurality of hot pressing stations can be distributed along a straight line below the hot pressing plate, so that the hot pressing mechanism can simultaneously hot press a plurality of battery pieces on the same straight line.

In another example, a plurality of hot pressing stations are distributed in a matrix manner below the hot pressing plate, so that the hot pressing mechanism can simultaneously hot press more battery pieces.

In an example, a plurality of first vacuum adsorption devices can be independently controlled, and when the number of the battery pieces needing to be adsorbed is less than that of the first vacuum adsorption devices, the idle vacuum adsorption devices can be controlled not to work, so that the battery pieces with the corresponding number can be adsorbed as required, and the application range is wide.

Specifically, as shown in fig. 3, a plurality of first vacuum suction devices 220 may be mated with a plurality of transfer stations D1 within the transfer region D. When the typesetting mechanism 200 moves to the transfer area D, the plurality of first vacuum suction devices 220 correspond to the plurality of transfer stations D1, so that the typesetting mechanism 200 can suck the plurality of battery pieces a in the transfer area D.

In practical applications, as shown in fig. 3, when the layout mechanism 200 transfers a plurality of battery pieces a, the first moving device 210 moves a plurality of first vacuum suction devices 220 to the transfer area D, each first vacuum suction device 220 corresponds to a battery piece a at the transfer station D1, and the first vacuum suction devices 220 suck the battery pieces a through the front surfaces of the battery pieces a. Then, the plurality of battery pieces a are simultaneously transferred to the corresponding layout positions of the back plate B by the first moving device 210.

In an alternative mode, the first vacuum adsorption device may include a first vacuum adsorption plate disposed at one end of the first moving device, and a first adsorption driving mechanism configured to drive the first vacuum adsorption plate to adsorb the battery pieces. When the battery piece is adsorbed, the first adsorption driving mechanism drives the first vacuum adsorption plate to adsorb the battery piece; after the battery piece is moved to the destination by the first moving device, the first vacuum adsorption driving mechanism stops driving the first vacuum adsorption plate, so that the battery piece is placed at the destination.

In one example, when the plurality of first vacuum adsorption devices are independently controlled, the first vacuum adsorption device may further include a lifting device, and the first vacuum adsorption plate is disposed at one end of the first moving device through the lifting device. When adsorbing or placing the battery piece, elevating gear makes first vacuum adsorption board to backplate one side protrusion, avoids adsorbing or placing the battery piece in-process, the battery piece contact on other first vacuum adsorption device and the backplate.

As shown in fig. 4 and 5, the first moving device 210 may include a guide frame 211, at least one moving base 212 slidably disposed on the guide frame 211, and at least one first driving mechanism for driving the moving base 212 to move; a plurality of first vacuum suction devices 220 are provided on the respective movable seats 212. The first driving mechanism may be a telescopic motor or a cylinder, but is not limited thereto.

As shown in fig. 4, the guiding frame 211 is disposed above the back plate B, and the plurality of first vacuum suction devices 220 can be driven by the moving base 212 to move to transfer the battery piece a.

As shown in fig. 4, a plurality of first vacuum suction devices 220 are disposed on the corresponding movable base 212, and the first driving mechanism drives the movable base 212 to move linearly along the guide frame 211. Accordingly, when the first moving device 210 moves the plurality of battery pieces a, the plurality of battery pieces a move in a straight line, thereby reducing a deviation caused by moving the battery pieces a.

In one example, as shown in fig. 5, the at least one typesetting mechanism 200 may further include a first posture adjustment mechanism 230, and the plurality of first vacuum suction devices 220 are connected to one end of the first moving device 210 through the first posture adjustment mechanism 230.

The typesetting mechanism 200 is used for transferring the plurality of battery pieces a from the row string area 810 to the corresponding typesetting positions of the backboard B.

As shown in fig. 6, the mobile platform 800 has a stringing area 810 for carrying a plurality of battery pieces a, and the stringing area 810 includes a stringing station 811 having a plurality of corresponding battery pieces a. In the production of the back contact solar cell module, as shown in fig. 4, after the plurality of cells a are turned to the transfer region D by the turning structure 100, as shown in fig. 8, the stringing mechanism 900 transfers the plurality of cells a from the corresponding transfer region D to the stringing region 810 of the moving platform 800, and before the cells a are transferred by the typesetting mechanism 200, the plurality of cells a are strung. Then, the mobile platform 800 moves the plurality of battery pieces a to the typesetting station E, and the typesetting mechanism 200 transfers the plurality of battery pieces a from the string arrangement region 810 to the corresponding typesetting positions of the backboard B. Therefore, the mobile platform 800 can move the cell a to the vicinity of the layout mechanism 200, and the layout mechanism 200 does not need to transfer the cell a from the transfer region D, so that the working stroke of the layout mechanism 200 is reduced, and the layout efficiency is improved. Moreover, the number of the battery pieces a moved by the mobile platform 800 at each time can be multiple times of the number of the battery pieces a rotated by the typesetting mechanism 200, so that the number of times of moving the battery pieces a by the mobile platform 800 is reduced, and the energy consumption is saved.

In an alternative, as shown in fig. 1 to 5, the plurality of battery pieces a transferred by the typesetting mechanism 200 at a time are distributed in an m × n matrix, where m and n are integers. Wherein m is more than or equal to 1, and n is more than 1; or m is more than 1, and n is more than or equal to 1. That is, the layout mechanism 200 transfers a single row, a single column, or a plurality of rows and columns of the battery pieces a at a time.

As shown in fig. 5, when the typesetting mechanism 200 includes a plurality of first vacuum suction devices 220, and the plurality of battery pieces a transferred each time are distributed in an m × n matrix, the plurality of first vacuum suction devices 220 are distributed in an m × n matrix.

The stringing station 811 on the movable platform 800 is at least equal to the number of cells a transferred by the typesetting mechanism 200 at a time.

For example, as shown in fig. 1, m is 1 and n is 6, and the typesetting mechanism 200 can transfer 6 battery pieces a at a time. In one example, a is 1 and b is 6. In practical applications, the turnover mechanism 100 includes 6 turnover mechanisms 110, the turnover mechanism 100 turns over 6 battery pieces a at a time, and the stringing mechanism 900 transfers 6 battery pieces a at a time. Based on this, the turnover structure 100 turns over the primary battery piece a, the string arrangement mechanism 900 transfers the primary battery piece a, the mobile platform 800 transfers the primary battery piece a to the typesetting mechanism 200, and the typesetting mechanism 200 transfers the primary battery piece a to the back plate B.

In another example, a-6 and b-6. In practical application, the turnover structure comprises 6 turnover mechanisms, the turnover structure turns over 6 battery pieces at each time, and the string arrangement mechanism transfers 6 battery pieces at each time. Based on this, the battery piece is once transferred to the composing mechanism to the upset six times battery piece of flip structure, row cluster mechanism, and the battery piece is once transferred to the composing mechanism to the moving platform, and the composing mechanism is six times battery piece to the backplate.

For another example, as shown in fig. 5, m is 3, n is 8, and the layout mechanism 200 can transfer 24 battery pieces a at a time. In one example, as shown in fig. 6, a is 3 and b is 8. In practical applications, the turnover mechanism 100 includes 8 turnover mechanisms 110, the turnover mechanism 100 turns over 8 battery pieces a at a time, and the stringing mechanism 900 transfers 8 battery pieces a at a time. Based on this, the turnover structure 100 turns over the tertiary battery piece a, the string arrangement mechanism 900 transfers the tertiary battery piece a, the mobile platform 800 transfers the primary battery piece a to the typesetting mechanism 200, and the typesetting mechanism 200 transfers the primary battery piece a to the back plate B.

As shown in fig. 4 to 8, since the plurality of turnover mechanisms 110 are arranged along the conveying direction of the battery pieces a, the plurality of battery pieces a in the conveying area D are arranged along a straight line. When the plurality of battery pieces a transferred by the layout mechanism 200 each time are distributed in an m × n matrix, where m > and n > 1, if the layout mechanism 200 transfers the battery pieces a directly from the transfer area D, the layout mechanism 200 may have a part of the area empty. The plurality of stringing stations 811 are distributed in an a × b matrix manner, a is greater than or equal to m, b is greater than or equal to n, a plurality of battery pieces a in the transfer area D can be repeatedly strung on the mobile platform 800 through the stringing mechanism 900, so that the number of the battery pieces a moved by the mobile platform 800 each time is not less than the number of the battery pieces a transferred by the typesetting mechanism 200 each time, no load of the typesetting mechanism 200 is avoided, more battery pieces a can be transferred by the typesetting mechanism 200 each time, and the typesetting efficiency is improved.

The guide rail 830 is arranged between the transfer area D and the typesetting station E, and the bearing platform 820 is slidably mounted on the guide rail 830. The second driving mechanism is used for driving the bearing table 820 to slide along the guide rail 830.

As shown in fig. 6, the carrier table 820 is slidably mounted on the guide rail 830, and the second driving mechanism is used for driving the carrier table 820 to slide along the guide rail 830. Accordingly, when the moving platform 800 moves the plurality of battery pieces a, the plurality of battery pieces a move along a straight line, thereby reducing deviation caused by moving the battery pieces a.

In one example, the bearing table is located at the stringing station and can comprise a first hollow-out part and a first bearing part. The first bearing part is used for bearing the battery piece, and the first hollow-out part corresponds to the area of the battery piece with the conductive material.

Specifically, the plummer can be located and arrange string station department and set up the through-hole, and the size of through-hole is less than the size of battery piece for the plummer is located through-hole department and is first fretwork portion, and the edge that the plummer is located the through-hole is first bearing portion.

In an alternative, as shown in fig. 7, the at least one stringing mechanism 900 includes a second moving device 910 and a plurality of second vacuum suction devices 920 located at one end of the second moving device 910. Each second vacuum adsorption device 920 is used for adsorbing a battery piece a, and the second moving device 910 is used for transferring a plurality of battery pieces a from the corresponding transfer area D to the corresponding stringing station 811 of the moving platform 800.

Wherein, the second posture adjustment mechanism 930 is a multi-degree-of-freedom angle adjustment mechanism; the second posture adjustment mechanism 930 adjusts the battery piece a adsorbed by the corresponding second vacuum adsorption device 920 to be horizontal, and drives the battery piece a to rotate.

As shown in fig. 8, the second posture adjustment mechanism 930 may adjust the battery piece a adsorbed by the corresponding second vacuum adsorption device 920, so that the battery piece a and the back plate B are accurately aligned. The second posture adjustment mechanism 930 adjusts the battery piece a adsorbed by the corresponding second vacuum adsorption device 920 to be horizontal, so that the connection process of the battery piece a and the backboard B is more stable and accurate. The second posture adjustment mechanism 930 can drive the battery piece a to rotate, so that the battery piece a and the backboard B are aligned accurately.

As a possible implementation manner, fig. 9 illustrates a schematic view of the third vacuum absorption plate in the transfer station in the embodiment of the present invention. Fig. 10 illustrates a schematic view of a third vacuum suction plate at a loading station in an embodiment of the present invention. As shown in fig. 9 and 10, the at least one turnover mechanism 110 includes at least one third vacuum suction plate 111, a third suction driving mechanism for driving the third vacuum suction plate 111 to suck the battery piece a, and a turnover driving mechanism 112 for driving the third vacuum suction plate 111 to turn over.

Specifically, as shown in fig. 9 and 10, the loading station C1 and the transfer station are respectively located on both sides of the turnover driving mechanism 112. When the back contact surface of the battery piece a is located at the feeding station C1, the turnover driving mechanism 112 may drive the third vacuum adsorption plate 111 to contact with the back contact surface of the battery piece a, and the third adsorption driving mechanism drives the third vacuum adsorption plate 111 to adsorb the back contact surface of the battery piece a. Then, the reverse driving mechanism 112 drives the third vacuum absorption plate 111 to reverse 180 °, and the back contact surface of the battery piece a is reversed from the corresponding loading station C1 to the transfer station D1. Finally, the third suction driving mechanism stops driving the third vacuum suction plate 111 to suck the back contact surface of the cell a, so that the back contact surface of the cell a located at the transfer station D1 faces downward, and the typesetting mechanism 200 can move the back contact surface of the cell a to the back plate B through the front surface of the back contact surface of the cell a.

Specifically, as shown in fig. 10, a through hole may be formed in the third vacuum adsorption plate 111, and the size of the through hole is smaller than that of the battery piece a, so that the second hollow portion is located at the through hole of the third vacuum adsorption plate 111, and the second bearing portion is located at the edge of the through hole of the third vacuum adsorption plate 111.

In one example, as shown in fig. 9, when the solar cell layout apparatus includes the first image collector 600 and the third vacuum suction plate 111 is at the transfer station D1, the first image collector 600 may be located below the second hollow portion. Based on this, when the third vacuum absorption plate 111 is located at the transfer station D1, the first image collector 600 is located below the second hollow portion, and the first image collector 600 can collect the image of the back contact surface of the battery piece a through the second hollow portion, so that the collected image is more accurate, and the first image collector 600 does not affect the operation of the turnover mechanism 110.

The embodiment of the invention also provides manufacturing equipment of the solar cell module, which comprises the solar cell typesetting equipment. The beneficial effects of the manufacturing equipment of the solar cell module are the same as those of the solar cell typesetting equipment, and are not repeated here.

The embodiment of the invention also provides a typesetting method of the solar cell, which is applied to the typesetting equipment of the solar cell. The typesetting method of the solar cell comprises the following steps:

step S100, controlling at least one group of turnover structures, wherein each group of turnover structures comprises a plurality of turnover mechanisms which are in contact with the back contact surfaces of the battery pieces, and turnover the battery pieces from corresponding loading stations to a transfer station so that the back contact surfaces of the battery pieces positioned at the transfer station face the direction of the plane where the back plate is positioned;

step S200, controlling at least one typesetting mechanism to contact with the front sides of the plurality of battery pieces, and transferring the plurality of battery pieces from the corresponding transfer areas to the corresponding typesetting positions of the back plate;

and step S300, controlling a hot-pressing mechanism to hot-press a plurality of battery pieces at corresponding typesetting positions of the back plate.

As a possible implementation manner, when the solar cell typesetting apparatus includes a first image collector, a second image collector, and a controller, the step S200 includes:

and step S210, controlling at least one first image collector to collect the image of the back contact surface of the battery piece on the corresponding transfer station, and sending the image of the back contact surface of the battery piece to the controller.

And controlling at least one second image collector to collect the typesetting image of the typesetting position of the backboard and sending the typesetting image to the controller.

And S220, controlling a typesetting mechanism to transfer the plurality of battery pieces to corresponding typesetting positions of the back plate by the controller according to the images of the back contact surfaces of the battery pieces and the typesetting images.

It should be noted that, in step S210, "control at least one first image collector to collect the image of the back contact surface of the battery piece at the corresponding transfer station, and send the image of the back contact surface of the battery piece to the controller. And controlling at least one second image collector to collect the typesetting images of the typesetting positions of the back plates and sending the typesetting images to the controller. "not in sequence, but also simultaneously.

In an alternative manner, the step S220 may include:

step S221: and comparing the image of the back contact surface of the battery piece with the reference battery piece image to determine the offset parameter of the battery piece. And comparing the typesetting image with the reference typesetting image, and determining the offset parameter of the typesetting position.

Step S222: and the controller determines the offset parameters of the battery pieces at the corresponding typesetting positions of the backboard according to the offset parameters of the battery pieces and the offset parameters of the typesetting positions.

Step S223: the controller controls the typesetting mechanism to transfer the battery pieces to the corresponding typesetting positions of the back plate according to the offset parameters.

It should be noted that, in step S221, the "comparing the image of the back contact surface of the cell with the reference cell image to determine the offset parameter of the cell" and the "comparing the layout image with the reference layout image to determine the offset parameter of the layout position" may be performed simultaneously or not in sequence.

In practical application, the typesetting logic can be set up first, and each typesetting mechanism typesets each cell piece at the corresponding typesetting position in sequence. Thus, each cell has theoretical coordinates on the back plate.

After the battery pieces are transferred and turned over, the positions of the battery pieces may be shifted from the preset positions. After the backboard is conveyed, the typesetting position on the backboard can also deviate from the preset position.

Therefore, the reference cell image may be preset. For example, the shooting angle of the first image collector is fixed every time the first image collector collects an image, so that an image with a non-offset battery slice is used as a reference battery slice image. After the actual image of the back contact surface of the battery piece is collected, if the battery piece deviates in the transferring and overturning processes, the position of the battery piece at the transfer station is different from the preset position, the image of the back contact surface of the battery piece can be compared with the reference battery piece image, and the deviation parameter of the battery piece is determined. If the battery piece is not deviated, the deviation parameter is 0.

The reference layout image may also be preset. For example, the shooting angle at each time the second image collector collects the images is made fixed, so that the images whose layout positions of the back plates are not shifted are taken as reference layout images. After the typesetting image at the actual typesetting position is collected, if the backboard shifts in the transmission process, the typesetting position is different from the preset position, and the shift parameter of the typesetting position can be determined by comparing the typesetting image with the reference typesetting image. If the typesetting position is not shifted, the shift parameter is 0.

And finally, determining the offset parameters of the battery pieces at the corresponding typesetting positions of the back plate according to the offset parameters of the battery pieces and the offset parameters of the typesetting positions, so as to adjust the theoretical coordinates of the battery pieces on the back plate, obtain the actual coordinates of the battery pieces on the back plate, and accurately align the battery pieces with the typesetting positions.

In an optional manner, when the solar cell typesetting apparatus includes a first moving device and a first vacuum adsorption device, the step S200 includes:

and step Sa, controlling at least one typesetting mechanism to adsorb the front sides of the plurality of battery pieces through the plurality of first vacuum adsorption devices.

And Sb, transferring the plurality of battery pieces from the corresponding transfer areas to the corresponding typesetting positions of the back plate through the first mobile device.

In a possible implementation manner, when the solar cell typesetting apparatus includes a mobile platform and at least one string arranging mechanism, the step S200 includes:

and step one, controlling at least one string arranging mechanism to transfer a plurality of battery pieces from the corresponding transfer area to the corresponding string arranging station of the mobile platform.

And step two, controlling the mobile platform to move to the typesetting station from the transfer area, and moving the plurality of battery pieces to the typesetting station.

And step three, controlling the typesetting mechanism to transfer the plurality of battery pieces from the string arrangement area to the corresponding typesetting position of the back plate.

As a possible implementation manner, the back contact surface of the at least one battery piece is provided with a plurality of first mark points. Based on the method, the offset of the battery piece can be determined by determining the offset of the first mark points, so that the speed of determining the offset of the battery piece is increased, and the working efficiency is improved. When the image of the back contact surface of the battery piece needs to be compared with the reference battery piece image to determine the offset parameter of the battery piece, the offset parameters of the first mark points can be determined by comparing the positions of the first mark points in the image, so that the offset parameter of the battery piece can be rapidly determined.

The back contact surface of at least one battery piece is provided with a plurality of first conductive parts and a plurality of first insulating parts. The first conductive portion may be a conductive contact. The plurality of first insulating portions may be connected as a whole.

The at least one first marker may be located at the respective first conductive portion or the respective first insulating portion. When the first mark point is arranged on the first insulating part, the first mark point does not influence the electric connection of the battery piece and the back plate, and the influence caused by the arrangement of the first mark point is reduced.

When the first mark point is disposed on the first insulating portion, the first mark point may be a conductive material. Note that the conductive material on the first insulating portion is not conductive. Based on this, when a plurality of conducting materials are printed on the back contact surface of the battery piece to form the conducting contact, the conducting material can be arranged at the first mark point position of the first insulating part at the same time, so that the conducting material positioned at the first insulating part forms the first mark point, the first mark point is not required to be arranged in an extra process, the production efficiency is improved, and the cost is saved.

As a possible implementation manner, the mounting surface of the back plate has a plurality of second mark points. Based on the method, the offset of the typesetting position can be determined by determining the offsets of the plurality of second mark points, so that the speed of determining the offsets of the typesetting position is increased, and the working efficiency is improved.

When the typesetting image needs to be compared with the reference typesetting image to determine the offset parameter of the typesetting position, the offset parameters of the second mark points can be determined by comparing the positions of the second mark points in the image, so that the offset parameter of the typesetting position can be quickly determined.

Wherein the at least one back plate has a plurality of second conductive parts and a plurality of second insulating parts. An opening is formed in the insulating layer of the back plate corresponding to the conductive contact of the battery piece, and the conductive layer is exposed out of the opening, so that a second conductive part is formed. The other area of the back plate is a second insulating part.

At least one second marking point is located on the corresponding second conductive part or the corresponding second insulating part. When the second mark point is arranged on the second insulating part, the second mark point does not influence the electric connection between the battery piece and the back plate, and the influence caused by the arrangement of the second mark point is reduced.

In one embodiment, at least one second marker point is arranged on one side of the conductive layer close to the insulating layer. For example, a pattern may be drawn on the conductive layer as a second marker point using a laser. The shape of the second marker point may be a cross, a circle, a triangle, a rectangle, or any other shape. The opening of the insulating layer, which is provided with the second mark point, is more than 1.1 times of the opening which is not provided with the second mark point, so that the second mark point can be more conveniently identified. When the second mark point is positioned on the second insulating part, the second mark point is arranged in the area of the conducting layer which is not connected with the conducting contact, and the insulating layer is positioned on the position of the second mark point and provided with the opening for exposing the second mark point.
