Technical Field

The invention relates to the technical field of display, in particular to a stripping mechanism and a Mylar tape attaching device.

Background

Mylar (Mylar) tape is a tape made of tough polyester polymer material, and is widely applied to the fields of electromechanics, electronics, information communication and the like because the Mylar tape has good heat resistance, excellent insulating property, good surface smoothness and high flexibility. In the conventional flat panel display device, a mylar tape is generally used to fix the display panel in the backlight module, and the mylar tape plays roles of fixing the display panel and shielding light.

Because one side of the mylar tape has viscosity, in order to ensure that the mylar tape has better viscosity when being used for sticking the display panel and the backlight module, the mylar tape is stuck on the release paper before being stuck on other parts, and the mylar tape and the release paper form the mylar sheet together. When the Mylar tape needs to be attached to other parts, the release paper only needs to be torn off from the Mylar tape.

In order to realize better separation of the Mylar tape and the release paper, the existing release paper is in a strip shape, a plurality of Mylar tapes are distributed at intervals along the length direction of the release paper, the Mylar sheets are arranged on the discharging device in a roll shape, the free ends of the Mylar sheet material rolls positioned on the outer side are arranged on the receiving device, and the Mylar sheets can be rolled from the discharging device to the receiving device through the matching of the receiving device and the discharging device. In the process that the Mylar film is rolled into the material receiving device, the transmission direction of the Mylar film can be changed from the horizontal direction to other directions, a manipulator capable of moving along the horizontal direction is arranged at the position where the transmission direction of the Mylar film changes, the manipulator can adsorb the Mylar tape, and through the matching of the manipulator, the material receiving device and the material rolling device, the release paper and the Mylar tape can be well separated.

The structure can realize better separation of the release paper from the common Mylar tape, but an IC chip for communication is arranged in the Mylar tape, and if the Mylar tape is matched with the long-strip release paper to form the roll-shaped Mylar tape, the IC chip is rolled and folded, so that the IC chip is damaged, and the communication function of the Mylar tape fails. Therefore, the mylar tape with the IC chip cannot form a roll with the long release paper, the mylar tape with the IC chip is usually combined with the sheet release paper to form the sheet mylar sheet, and the mylar tape and the release paper in the sheet mylar sheet are usually separated by manual operation, so that the efficiency of separating the mylar tape from the release paper is low.

Accordingly, a release mechanism and a mylar tape attaching device are needed to solve the problem of low separation efficiency between mylar tape and release paper in a sheet-shaped mylar sheet.

As shown in fig. 1, a mylar tape 301 with an IC chip is generally combined with a release paper 302 in a sheet form to form a mylar sheet 300 in a sheet form, and in order to fix a display panel to a backlight unit with the mylar tape 301 with an IC chip, the mylar tape 301 needs to be first peeled off from the release paper 302, and therefore, a peeling mechanism for separating the mylar tape 301 from the release paper 302 is provided in the mylar tape attaching apparatus.

As shown in fig. 2, the present embodiment provides a peeling mechanism 100 for separating a mylar tape 301 with an IC chip from a sheet-like release paper 302, the peeling mechanism 100 including a storage member 5, a transfer member 6, and a peeling station.

As shown in fig. 2, the transfer unit 6 is configured to take out the mylar sheet 300 located at the uppermost layer in the accommodating groove, transfer the taken-out mylar sheet 300 to a peeling station of the peeling mechanism 100, and peel the mylar tape 301 and the release paper 302 at the peeling station. To facilitate understanding of the specific structure of the transfer assembly 6, as shown in fig. 3, the transfer assembly 6 includes a guide rail 61, a first motor 62, a lifting cylinder 63, a support frame 64, and a suction head 65. The guide rail 61 is hollow, the guide rail 61 is internally provided with a lead screw nut mechanism, a lead screw of the lead screw nut mechanism is parallel to the extending direction of the guide rail 61, two ends of the lead screw are rotatably connected with the guide rail 61, one end of the lead screw extends out of the guide rail 61 and is connected with an output end of the first motor 62, a nut of the lead screw nut mechanism is connected with the lifting cylinder 63, and the lifting cylinder 63 can slide relative to the guide rail 61 along the extending direction of the guide rail 61.

The lifting cylinder 62 moving above the accommodating groove can drive the supporting frame 64 to move in the vertical direction, so that adsorption of the Mylar films 300 at different heights can be realized. When the support frame 64 moves to a position right above the mylar sheet 300 to be sucked, the vacuum suction device starts to operate, so that the suction of the mylar sheet 300 by the suction head can be realized. When the conveying component 6 drives the adsorbed mylar sheet 300 to move to the stripping station, the vacuum adsorption device stops working, and therefore the mylar sheet 300 to be stripped can be placed to the stripping station to be stripped.

In order to realize the peeling of the mylar tape 301 and the release paper 302 of the sheet mylar sheet 300, as shown in fig. 4, the peeling station of this embodiment includes an adsorption belt 1, a first driving component 2 and an adsorption component 3, wherein the adsorption belt 1 can adsorb the release paper 302, the first driving component 2 can drive the adsorption belt 1 to transmit, and the first driving component 2 can switch the transmission direction of the adsorption belt 1 from a first direction to a second direction at a first position, the first direction and the second direction are arranged at an included angle, the adsorption component 3 is arranged near the first position, and the adsorption component 3 can adsorb the mylar tape 301, and the adsorption component 3 can also drive the mylar tape 301 to move synchronously with the adsorption belt 1 along the first direction. Through the movement mode of the adsorption belt 1 and the adsorption component 3, the Mylar tape 301 and the release paper 302 of the sheet-shaped Mylar film 300 are separated at the first position, the separation mode replaces the manual separation mode in the prior art, and the separation efficiency of the Mylar tape 301 and the release paper 302 in the sheet-shaped Mylar film 300 is improved. The peel mechanism 100 of the mylar tape attaching apparatus according to the present embodiment can improve the attaching efficiency of the mylar tape 301.

Specifically, in order to achieve a good adsorption effect of the adsorption tape 1 on the release paper 302, the adsorption tape 1 may be an adhesive tape having one side with adhesiveness, so that the situation that the release paper 302 and the mylar tape 301 cannot be separated due to the fact that the release paper 302 and the mylar tape 301 have too large adhesiveness can be avoided, and separation of the release paper 302 and the mylar tape 301 is facilitated.

Specifically, the suction assembly 3 in this embodiment includes a mechanical arm capable of performing multi-axis movement and multi-axis rotation, a suction cup is provided at a free end of the mechanical arm, a plurality of through holes are provided in the suction cup, one end of each through hole is opposite to the mylar tape 301, and the other end of each through hole is communicated with a vacuum suction device.

Specifically, for convenience of understanding the specific structure and the operation principle of the first driving assembly 2, as shown in fig. 4, the first driving assembly 2 includes a material receiving wheel 21, a material discharging wheel 22, and a driving device, one end of the adsorption belt 1 is connected to the material receiving wheel 21, the other end of the adsorption belt 1 is connected to the material discharging wheel 22, and the driving device can drive the material receiving wheel 21 to rotate, so that the transportation of the adsorption belt 1 can be realized. Specifically, the driving device in this embodiment may be the second motor 24, and the second motor 24 and the receiving wheel 21 are arranged in the horizontal direction, so that the size of the peeling mechanism 100 in the direction perpendicular to the paper surface can be effectively reduced, and the overall layout of the peeling mechanism 100 in the direction perpendicular to the paper surface is more compact.

In addition, in order to transmit the power of the second motor 24 to the take-up pulley 21, a pulley is respectively arranged on the output end of the second motor 24 and the rotating shaft of the take-up pulley 21, an endless belt is jointly tensioned on the peripheries of the two pulleys, and the second motor 24 can transmit the power of the output shaft to the take-up pulley 21 through the connection of the pulley and the endless belt. In addition, in order to realize the better tensioning effect with adsorption band 1, transmission assembly 6 still includes a plurality of take-up pulleys, and material receiving wheel 21, blowing wheel 22 and a plurality of take-up pulleys are together with adsorption band 1 tensioning, avoid adsorption band 1 the phenomenon of relaxing to appear, guarantee adsorption band 1's normal transmission. In addition, the tensioning wheel is arranged on the frame of the peeling mechanism 100, and the relative position of the tensioning wheel relative to the frame of the peeling mechanism 100 is adjustable, so that the material receiving wheel 21, the material discharging wheel 22 and the tensioning wheels can be ensured to always tension the adsorption belt 1 together.

The release paper 302 is adsorbed on the adsorption band 1, similar to the manual separation of the mylar tape 301 and the release paper 302 by a person, when the angle of the adsorption band 1 at the first position is larger, the separation effect of the mylar tape 301 and the release paper 302 is better. In order to make the angle of the suction belt 1 changed in the first position larger, as shown in fig. 5, the first driving assembly 2 further includes a reversing knife edge 23 disposed in the first position, the reversing knife edge 23 includes a first guide surface 231 and a second guide surface 232 disposed at an included angle, the first guide surface 231 makes the suction belt 1 conveyed in the first direction, and the second guide surface 232 makes the suction belt 1 conveyed in the second direction, so that the angle of the suction belt changed in the first position can be larger. In addition, to further enhance the peeling effect, the included angle is an acute angle.

In addition, if the below of adsorption band 1 is in unsettled state, then the sucking disc of inconvenient adsorption component 3 adsorbs striding across the drawing sticky tape 301, in order to make adsorption component 3's sucking disc have better adsorption effect to striding across the drawing sticky tape 301, peeling means 100 still includes the backup pad 4 with the relative setting of adsorption component 3, the adsorption band 1 of transmission along first direction can be supported to backup pad 4, can avoid striding across the drawing sticky tape 301 and be in unsettled state, guarantee that adsorption component 3 is to inhaling the better adsorption effect of taking 1.

In addition, some mylar tapes 301 are generally provided with small protruding lug structures along both sides in the length direction, and in the prior art, the tearing action of the release paper 302 from the mylar tape 301 is generally performed from one side in the width direction of the mylar tape 301, and if the mylar tape 301 has a certain hardness, the tearing action does not affect the structural integrity of the mylar tape 301. However, if the mylar tape 301 is inherently soft, the tearing may deform the tab structure on the mylar tape 301, thereby interfering with subsequent use of the mylar tape 301.

In order to solve the above problem, in the present embodiment, the longitudinal direction of the mylar tape 301 is set to extend in the first direction, so that when the mylar tape 301 is separated from the release paper 302, the peeling mechanism 100 tears the release paper 302 from one side of the mylar tape 301 in the longitudinal direction, and even if the mylar tape 301 is soft, the tearing manner does not damage the lug structure, thereby ensuring the integrity of the mylar tape 301 after being peeled.

In order to fix the mylar tape 301 to the display device 400 well and to make the mylar tape 301 cover the display panel and the backlight module, the mylar tape attaching device in this embodiment further includes the reverse folding mechanism 200.

For the sake of easy understanding of the specific structure and operation principle of the reverse folding mechanism 200, the structure and operation principle of the reverse folding mechanism 200 will now be described with reference to fig. 6 to 8.

As shown in fig. 6, the display device 400 includes a back plate 401, a CF substrate 402, and a polarizer 403 arranged from bottom to top, and the reverse folding mechanism 200 can cover one end of the mylar tape 301 on the front surface of the CF substrate 402 and cover the other end of the mylar tape 301 on the back surface of the back plate 401, so that the mylar tape 301 can fix the display device 400 as a whole.

Specifically, as shown in fig. 6 to 8, the invagination mechanism 200 includes a support 201, an upper pressing assembly 202, a lower pressing assembly 203, a second driving assembly and an elastic assembly 206, wherein the upper pressing assembly 202 and the lower pressing assembly 203 are respectively rotatably connected to the support 201, the upper pressing assembly 202 and the lower pressing assembly 203 are arranged along a vertical direction, the second driving assembly can drive the support 201 to move along a thickness direction of the display device 400, the second driving assembly can also drive the support 201 to move in a direction approaching or departing from the display device 400 in a horizontal plane, and the elastic assembly 206 can enable the upper pressing assembly 202 and the lower pressing assembly 203 to approach each other. Specifically, the second driving assembly in this embodiment may be a robot capable of moving in multiple directions, and the elastic assembly 206 may be a spring.

The specific working principle of the invagination mechanism 200 is as follows: the mylar tape 301 is located above the CF substrate 402, the sticky side of the mylar tape 301 faces the CF substrate 402, the second driving assembly first drives the upper pressing assembly 202 and the lower pressing assembly 203 to be located right above the mylar tape 301, the second driving assembly then drives the upper pressing assembly 202 and the lower pressing assembly 203 to move along the vertical direction (Y direction), and the mylar tape 301 extending out of one side of the display device 400 is forced downwards by the upper pressing assembly 202 and the lower pressing assembly 203, so that the mylar tape 301 extending out of one side of the display device 400 is folded downwards. The second driving assembly drives the support 201 to move downwards, so that the free end of the pressing assembly 203 is opposite to the mylar tape 301 below the display device 400, and the second driving assembly drives the support 201 to move towards the horizontal direction (X direction) close to the display device 400, so that the mylar tape 301 below the display device 400 is folded, and the portion of the mylar tape 301 is adhered to the back surface of the back plate 401.

And because the upper pressing component 202 and the lower pressing component 203 are connected through the elastic component 206, the upper pressing component 202 can be ensured to be always abutted against the mylar tape 301 on the front surface of the CF substrate 402, the lower pressing component 203 can be ensured to be always abutted against the mylar tape 301 on the back surface of the back plate 401, and in the process that the second driving component drives the upper pressing component 202 and the lower pressing component 203 to move along the horizontal direction, the leveling effect on the mylar tape 301 can be realized, the adhering effect of the mylar tape 301 and the display device 400 is better, and the mylar tape 301 is prevented from falling off from the display device 400 in the using process of the display device 400.

Specifically, the pressing assembly 202 includes a first link 2021 and a first roller 2022, the first link 2021 is rotatably connected to the bracket 201, and the first roller 2022 is rotatably disposed at a free end of the first link 2021. The pressing assembly 203 includes a second link 2031 and a second roller 2032, the second link 2031 is rotatably connected to the bracket 201, and the second roller 2032 is rotatably disposed at a free end of the second link 2031, and is disposed by the first roller 2022 and the second roller 2032. When the upward pressing assembly 202 and the downward pressing assembly 203 perform a smoothing action on the mylar tape 301, the first roller 2022 and the second roller 2032 are arranged to ensure that the upward pressing assembly 202 and the downward pressing assembly 203 are in rolling contact with the mylar tape 301 respectively, so that the damage of the upward pressing assembly 202 and the downward pressing assembly 203 on the mylar tape 301 can be avoided, and the long service life of the mylar tape 301 is ensured. Furthermore, the first roller 2022 and the second roller 2032 in this embodiment may be made of an elastically deformable material such as rubber, which can prevent the first roller 2022 and the second roller 2032 from being in hard contact with the mylar tape 301, further prevent the mylar tape 301 from being damaged, and further improve the service life of the mylar tape 301.

In order to further improve the adhesion effect of the mylar tape 301 on the side of the display device 400 to the display device 400, the invagination mechanism 200 further includes a leveling member 205, the leveling member 205 extends from one side of the bracket 201, a free end of the leveling member 205 protrudes from a gap between the upper pressing member 202 and the lower pressing member 203, and the free end of the leveling member 205 is configured to level the side of the display device 400. In particular, as shown in Figs. 7 and 8, the smoothing assembly 205 comprises a flexible bristle 2051 and a telescoping section 2052, wherein one end of the telescoping section 2052 is connected to the carrier 201 and the other end of the telescoping section 2052 is connected to the flexible bristle 2051. By providing the extension part 2052 between the flexible brush head 2051 and the holder 201, the flexible brush head 2051 can be ensured to be always in contact with the mylar tape 301 located on the side surface of the display device 400, and specifically, the extension part 2052 in this embodiment may be a spring or an extension rod. When the push-up unit 202 and the push-down unit 203 are horizontally moved toward the display device 400, the flexible brush head 2051 is abutted on the mylar tape 301 located on the side surface of the display device 400 by the expansion and contraction part 2052, so that the effect of the flexible brush head 2051 on the mylar tape 301 located on the side surface of the display panel 400 can be realized.

In addition, since the first link 2021 and the second link 2031 are hard, if the top pressing member 202 and the bottom pressing member 203 apply downward force to the mylar tape 301 extending out of the display device 400, the mylar tape 301 extending out of the display device 400 is folded downward, which may cause damage to the mylar tape 301 extending out of the display device 400. In order to solve the above problem, in this embodiment, the leveling component 205 can be used to apply a downward force to the mylar tape 301 extending out of the display device 400, and since the flexible bristles 2051 are soft, damage to the mylar tape 301 can be effectively avoided, and the life of the mylar tape 301 can be prolonged.

For ease of understanding, the respective operating principles of the peeling mechanism 100 and the reverse folding mechanism 200 will now be described.

With reference to fig. 2, 3 and 5, the peeling mechanism 100 operates on the following principle:

as shown in fig. 2 and 3, first, the first motor 62 is operated to transfer the lifting cylinder 63 to the position right above the corresponding storage module 5 along the extending direction of the guide rail 61, the output end of the lifting cylinder 63 moves downward to bring the suction head 65 into contact with the topmost mylar sheet 300 in the storage module 5, the suction head 65 sucks the topmost mylar sheet 300, the output end of the lifting cylinder 63 moves upward to lift the topmost mylar sheet 300 to the position above the storage module 5, the lifting cylinder 63 is transferred to the position above the suction belt 1 along the extending direction of the guide rail 61 after the first motor 62 is reversed, the output end of the lifting cylinder 63 moves downward, the suction head 65 releases the mylar sheet 300, therefore, the Mylar film 300 is placed on the adsorption belt 1, the release paper 302 of the Mylar film 300 is positioned below the Mylar tape 301 is positioned above the Mylar tape, the adsorption belt 1 is used for adhering and fixing the release paper 302, and the Mylar film 300 is conveyed along with the adsorption belt 1.

As shown in fig. 5, when the mylar sheet 300 is transferred to the first position of the reversing blade 23, the adsorption component 3 adsorbs the mylar tape 301 from above the mylar tape 301, the adsorption component 3 drives the mylar tape 301 to move continuously along the first direction, the moving speed of the adsorption component 3 is the same as the transfer speed of the adsorption tape 1, and the adsorption tape 1 drives the release paper 302 to move along the second direction, so that the release paper 302 can be peeled off from the mylar tape 301. The suction unit 3 then transports the peeled mylar tape 301 to a subsequent station, and covers the mylar tape 301 outside the display device 400.

With reference to fig. 6 to 8, the operation principle of the reverse folding mechanism 200 is as follows:

as shown in fig. 6, the mylar tape 301 is located above the CF substrate 402, and the sticky side of the mylar tape 301 faces the CF substrate 402, the second driving component first drives the flexible bristles 2051 to be located above the mylar tape 301, and the second driving component then moves the flexible bristles 2051 in the vertical direction (Y direction) to stick the portion of the mylar tape 301 above the CF substrate 402 to the CF substrate 402. The second driving component drives the flexible brush head 2051 to move leftwards, so that the flexible brush head 2051 is aligned with the side face of the back plate 401 along the vertical direction, the second driving component drives the flexible brush head 2051 to move along the vertical direction, the flexible brush head 2051 applies force downwards to the Mylar tape 301 extending out of one side of the display device 400, and the Mylar tape 301 extending out of one side of the display device 400 is turned downwards.

As shown in fig. 7 and 8, the second driving assembly further aligns the flexible bristles 2051 with the side surface of the back plate 401, and the second driving assembly further drives the bracket 201 to move toward the horizontal direction (X direction) close to the back plate 401, so that the flexible bristles 2051 can be closely abutted against the side surface of the display device 400, and the mylar tape 301 located on the side surface of the display device 400 can be closely attached to the display device 400. On the other hand, since the upper pressing component 202 and the lower pressing component 203 are connected through the elastic component 206, the upper pressing component 202 can be ensured to be always abutted against the mylar tape 301 on the front surface of the CF substrate 402, and the lower pressing component 203 can be ensured to be always abutted against the mylar tape 301 on the back surface of the back plate 401, and in the process that the second driving component drives the upper pressing component 202 and the lower pressing component 203 to move along the horizontal direction, the upper pressing component 202 and the lower pressing component 203 can achieve the leveling effect on the mylar tape 301 on the front surface of the CF substrate 402 and the mylar tape 301 on the back surface of the back plate 401, so that the attaching effect of the mylar tape 301 and the display device 400 is better, the dropping of the mylar tape 301 in the using process of the display device 400 is avoided, and the service life of the display device 400 is prolonged.
