Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 2 and 3, the bus bar punching auxiliary device according to the embodiment of the invention includes a protecting member 10 and a straightening member 20, wherein a cavity 11 is formed inside the protecting member 10, the cavity 11 is configured to be sleeved on an end of a bus bar lead-out wire 40, and the straightening member 20 is configured to straighten the protecting member 10.

Specifically, the bus bar perforation assisting device is used for assisting the bus bar lead-out wires 40 of the dual glass assembly to pass through the backplane glass hole 51, wherein the maximum outer diameter of the protecting member 10 is smaller than the aperture of the backplane glass hole 51, so that the protecting member 10 can pass through the backplane glass hole 51, and the straightening member 20 can straighten the protecting member 10 by magnetic force, electrostatic force or other acting force so that the protecting member 10 is in a substantially vertical state.

According to the bus bar perforation auxiliary device provided by the embodiment of the invention, the protection piece 10 is sleeved at the end part of the bus bar leading-out wire 40 before the double-glass assembly is combined, the protection piece 10 is straightened by the straightening piece 20 to enable the protection piece 10 to be in a vertical state, the protection piece 10 penetrates through the backboard glass hole 51 in the double-glass assembly combining process, and the bus bar leading-out wire 40 penetrates through the backboard glass hole 51, so that the bus bar perforation auxiliary device realizes automation of the double-glass assembly combining process, improves the production efficiency, saves the labor force and further reduces the production cost.

According to some embodiments of the present invention, the protective member 10 is a magnetic material member, and accordingly, the alignment member 20 is a magnetic member, such as the generally described iron block (protective member 10) and magnet (alignment member 20).

Preferably, the protector 10 is made of a ferromagnetic material, and more preferably, the surface of the protector 10 is provided with a nickel-plated layer, so that the protector 10 can be prevented from being oxidized to increase the service life of the protector 10. Accordingly, alignment member 20 is a neodymium iron ferromagnetic member. Therefore, the magnetic force of the magnetic part has strong penetrability, and the magnetic part is further ensured to straighten the protection part 10 to enable the protection part 10 to be in a vertical state, and the cost is low.

Preferably, the bus bar punching auxiliary device further includes a lifting mechanism 30, the magnetic member (i.e., the straightening member 20) is disposed on the lifting mechanism 30, and the lifting mechanism 30 is capable of lifting or lowering the magnetic member to adjust a distance between the magnetic material member (the protecting member 10) and the magnetic member. Specifically, when a predetermined distance is reached between the protector 10 and the magnetic member, the magnetic member magnetically aligns the protector 10, so that the magnetic member is lifted or lowered by the lifting mechanism 30 to adjust the distance between the protector 10 and the magnetic member, thereby aligning the protector 10 when the two-glass assembly is assembled.

Further preferably, the lifting mechanism 30 includes a bracket 31 and a cylinder 32 connected to the bracket 31, and the magnetic member is disposed on the bracket 31. Specifically, the air cylinder 32 is disposed below the bracket 31, and the bracket 31 is lifted or lowered by the telescopic movement of the air cylinder 32.

Preferably, the protecting member 10 and the straightening member 20 each include a plurality of straightening members 20 for being disposed under the plurality of protecting members 10 in a one-to-one correspondence. By including a plurality of straightening members 20, each straightening member 20 straightens its associated protector 10, thereby facilitating cost savings.

According to some embodiments of the present invention, the protector 10 includes a tip portion 12 and a cylindrical portion 13 located below the tip portion 12, the tip portion 12 being formed in a tapered shape or a frustum shape. The protector 10 includes the tip portion 12 so that the precision requirement of the sheet combining machine in the double glass assembly sheet combining process can be greatly reduced.

Preferably, the outer diameter of the tip end of the frustum-shaped tip portion 12 is 1 to 2 mm. Not only is the precision requirement on the sheet combining machine reduced, but also the back plate glass 50 is prevented from being damaged in the sheet combining process.

The punching method of the bus bar punching auxiliary device of the embodiment of the invention comprises the following steps:

step S1, sleeving the cavity of the protection piece on the end part of the bus bar outgoing line of the double-glass assembly;

step S2, straightening the protection piece by utilizing a straightening piece;

and step S3, penetrating the protection piece through the backboard glass hole so that the bus bar lead-out wire penetrates through the backboard glass hole.

The use of the bus bar punching auxiliary device according to the embodiment of the present invention for double-glass assembly lamination will be further described below.

As shown in fig. 4, after an adhesive film is applied to the battery string of the dual glass assembly, the protector 10 (the protector 10 is made of a ferromagnetic material and has a nickel-plated layer formed on the surface thereof) is fitted over the end of the bus bar lead-out wire 40, then the panel glass 60 of the dual-glass assembly is conveyed to a laminating station through an assembly line, the glass sucker 70 moves the back panel glass 50 to the upper part of the panel glass 60 and adjusts the back panel glass to align the panel glass 60 and the back panel glass 50, the lifting mechanism 30 drives the straightening piece 20 to be lifted to a position which is about 5mm below the panel glass 60, wherein, the straightening member 20 is made of a ferromagnetic neodymium iron, and at this time, because a magnetic force is generated between the protecting member 10 and the straightening member 20, under the action of magnetic force, the protection member 10 is aligned to be in a vertical state, so that the tip end portion 12 is positioned below the backboard glass hole 51, and the glass suction cup 70 descends to enable the protection member 10 to penetrate through the backboard glass hole 51, thereby completing the sheet combination. After the sheet combination is completed, the lifting mechanism 30 drives the straightening member 20 to descend, and the dual glass assembly is conveyed to any process before lamination to take off the protection member 10, wherein the protection member 10 can be reused.

As shown in fig. 5, a destructive test was performed on the bus bar punching auxiliary device according to the embodiment of the present invention, such that the protection member 10 was placed between the panel glass 60 and the back plate glass 50 and deviated from the back plate glass hole 51, the glass chuck 70 pressed the back plate glass 50 to simulate the sheet combination failure situation, when the horizontal distance between the protection member 10 and the glass chuck 70 was 400mm, 10 dual glass assemblies were taken, each dual glass assembly was simulated for 20 times, no glass burst situation occurred, and the protection member 10 was always kept in a vertical state after the sheet combination failure. In the implementation process, when the sheet combination fails, only one end of the backboard glass 50 needs to be slightly lifted on line, and the protection piece 10 penetrates through the backboard glass hole 51, so that the average working time is about 5 s.

Use above-mentioned busbar auxiliary device that punches a hole to carry out dual glass assembly and close the piece, close the piece success rate and be 99.2%, almost no productivity loss satisfies mass production completely.
