Description

Technical Field

[0001] The present invention relates to the technical field of solar cells, and in particular to a busbar punching auxiliary device and a punching method using the same. Background Art

[0002] During the production process, double-glass components need to be assembled. Figure 1 The figure shows a schematic diagram of conventional double-glass module assembly. Before assembly, the panel glass needs to be placed in the specified position, and then the automatic glass loading machine will assemble the panels. Because there is a layer of film between the battery string and the panel glass, the uneven film causes the bus bar lead wire to be skewed in an unfixed direction, resulting in the bus bar lead wire being unable to pass through the back glass hole during the assembly process. If the assembly continues, the bus bar lead wire will be flattened by the back glass, and rework is required, which seriously affects production efficiency. At present, the industry uses manual assistance to adjust the bus bar lead wire to align it with the back glass hole to complete the assembly, which increases production costs. Summary of the invention

[0030] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figure 2 and Figure 3 As shown, the busbar perforation auxiliary device according to an embodiment of the present invention includes a protective member 10 and a straightening member 20. A cavity 11 is formed inside the protective member 10. The cavity 11 is used to be sleeved on the end of the busbar lead-out line 40. The straightening member 20 is used to straighten the protective member 10.

[0032] Specifically, the busbar perforation auxiliary device is used to assist the busbar lead-out line 40 of the double-glass component to pass through the back glass hole 51, wherein the maximum outer diameter of the protective member 10 is smaller than the aperture of the back glass hole 51, so that the protective member 10 can pass through the back glass hole 51, and the straightening member 20 can straighten the protective member 10 through magnetic force, electrostatic force or other forces so that the protective member 10 is in a roughly vertical state.

[0033] According to the busbar perforation auxiliary device of the embodiment of the present invention, since it includes a protective member 10 and a straightening member 20, before the double-glass assembly is assembled, the protective member 10 is sleeved on the end of the busbar lead-out line 40, and the protective member 10 is straightened by the straightening member 20 so that the protective member 10 is in a vertical state. In the double-glass assembly process, the protective member 10 passes through the back plate glass hole 51, and then the busbar lead-out line 40 passes through the back plate glass hole 51, so that the busbar perforation auxiliary device realizes the automation of the double-glass assembly process, improves production efficiency, saves labor, and thus reduces production costs.

[0034] According to some embodiments of the present invention, the protection member 10 is a magnetic material member, and correspondingly, the straightening member 20 is a magnetic member, for example, the commonly described iron block (protection member 10) and magnet (straightening member 20).

[0035] Preferably, the protective member 10 is made of ferromagnetic material, and more preferably, a nickel-plated layer is provided on the surface of the protective member 10, so as to prevent the protective member 10 from being oxidized and increase the service life of the protective member 10. Accordingly, the straightening member 20 is made of a strong magnetic member made of neodymium iron. Thus, it can be ensured that the magnetic force of the magnetic member has strong penetration, thereby ensuring that the magnetic member straightens the protective member 10 so that the protective member 10 is in a vertical state, and the cost is low.

[0036] Preferably, the busbar perforation auxiliary device further comprises a lifting mechanism 30, on which the magnetic member (i.e., the straightening member 20) is disposed, and the lifting mechanism 30 can lift or lower the magnetic member to adjust the distance between the magnetic material member (protective member 10) and the magnetic member. Specifically, when the distance between the protective member 10 and the magnetic member reaches a predetermined distance, the magnetic member can straighten the protective member 10 through the action of magnetic force, thereby lifting or lowering the magnetic member through the lifting mechanism 30 to adjust the distance between the protective member 10 and the magnetic member, so that when the double-glass assembly is assembled, the distance between the protective member 10 and the magnetic member reaches a predetermined distance to straighten the protective member 10.

[0037] Further preferably, the lifting mechanism 30 includes a bracket 31 and a cylinder 32 connected to the bracket 31, and the magnetic member is arranged on the bracket 31. Specifically, the cylinder 32 is arranged below the bracket 31, and the bracket 31 is lifted or lowered by the telescopic movement of the cylinder 32.

[0038] Preferably, the protective member 10 and the straightening member 20 are both included in plurality, and the plurality of straightening members 20 are used to be arranged one by one under the plurality of protective members 10. By including a plurality of straightening members 20, each straightening member 20 straightens the corresponding protective member 10, thereby facilitating cost saving.

[0039] According to some embodiments of the present invention, the protective member 10 includes a tip portion 12 and a cylindrical portion 13 located below the tip portion 12, and the tip portion 12 is formed in a cone or a frustum. The protective member 10 includes the tip portion 12, thereby greatly reducing the precision requirements of the laminating machine in the double-glass assembly laminating process.

[0040] Preferably, the outer diameter of the top of the frustum-shaped tip portion 12 is 1-2 mm, which not only ensures that the precision requirement for the lamination machine is reduced, but also prevents damage to the back plate glass 50 during the lamination process.

[0041] The punching method using the busbar punching auxiliary device of the embodiment of the present invention comprises the following steps:

[0042] Step S1, sleeve the cavity of the protective member on the end of the busbar lead-out line of the double-glass assembly;

[0043] Step S2, aligning the protective member using an alignment member;

[0044] Step S3, passing the protective member through the back plate glass hole so that the bus bar lead wire passes through the back plate glass hole.

[0045] Next, in combination with the busbar punching auxiliary device according to the embodiment of the present invention, the use of the busbar punching auxiliary device according to the embodiment of the present invention is further described to perform double-glass assembly.

[0046] like Figure 4 As shown, after laying the adhesive film on the battery string of the double-glass component, the protective member 10 (the protective member 10 is made of ferromagnetic material and a nickel-plated layer is formed on its surface) is put on the end of the busbar lead-out line 40, and then the panel glass 60 of the double-glass component is transferred to the assembly station via the assembly line, the glass suction cup 70 moves the back glass 50 to the top of the panel glass 60 and adjusts it to align the panel glass 60 and the back glass 50, and the lifting mechanism 30 drives the straightening member 20 to rise to about 5 mm below the panel glass 60, wherein the straightening member 20 is a neodymium iron strong magnetic member. At this time, due to the magnetic force generated between the protective member 10 and the straightening member 20, under the action of the magnetic force, the protective member 10 is corrected to a vertical state, so that its tip 12 is located below the back glass hole 51, and the glass suction cup 70 descends to allow the protective member 10 to pass through the back glass hole 51 to complete the assembly. After the assembling is completed, the lifting mechanism 30 drives the straightening member 20 to descend, and the protective member 10 is removed when the double-glass assembly is transferred to any process before lamination, wherein the protective member 10 is reusable.

[0047] like Figure 5 As shown, a destructive experiment was conducted on the busbar perforation auxiliary device of the embodiment of the present invention, where the protective member 10 was placed between the panel glass 60 and the back glass 50 and deviated from the back glass hole 51, and the glass suction cup 70 pressed down on the back glass 50 to simulate the failure of the assembly. When the horizontal distance between the protective member 10 and the glass suction cup 70 was 400 mm, 10 double-glass assemblies were taken, and each double-glass assembly was simulated 20 times, and no glass explosion occurred. After the assembly failed, the protective member 10 always remained in a vertical state. In the specific implementation process, when the assembly failed, only one end of the back glass 50 needs to be slightly lifted online, and the protective member 10 needs to be passed through the back glass hole 51, and the average working time is about 5 seconds.

[0048] The above-mentioned busbar perforation auxiliary device is used to perform double-glass module assembly, with a assembly success rate of 99.2%, almost no production capacity loss, and fully meets the requirements of mass production.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
