Description

Technical Field

[0001] This utility model relates to the field of battery cell stacking technology, and more specifically, to a multi-compatible stacking welding machine welding fixture. Background Technology

[0002] As the photovoltaic industry evolves towards larger sizes (such as 210mm*105 / 230*115mm) and multiple technology routes (TOPCon / HJT / XBC), the need for shingled welding fixtures (such as...) is growing. Figure 1 The existing welding fixture (shown as an example) needs to support different cell sizes with multiple busbars, ranging from 125-260mm. For different sizes of multi-busbar cells, such as HJT 210*10524BB and TOPCon 210*18216BB, the corresponding shingling fixture must be switched promptly. Switching between models requires removing the shingling module fixture and replacing it with one adapted to the current multi-busbar cell. For example, switching from PERC182*182 (10BB) cells to TOPCon182*182 (16BB) cells. The tooling for disassembling PERC182*182 (10BB) solar cells is distributed in three groups on the left, middle and right sides of the machine, with six in each group. Each welding tool is fixed by three 2.5mm*3mm flat-head Phillips head screws. After disassembly, the tooling is replaced with a special welding tooling for TOPCon 182*182 (16BB) solar cells. The switching is difficult, time-consuming and has low efficiency. Utility Model Content

Detailed Implementation

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 2 to 6 As shown, this embodiment provides a multi-compatible lap welding machine welding fixture, including:

[0033] Strip support plate 10;

[0034] Module placement slot 11 is formed on strip support plate 10;

[0035] Welding module 12, several welding modules 12 are slidably installed in module placement slot 11, each welding module 12 corresponds to two welding strips;

[0036] Top block fixing assembly 13, two sets of top block fixing assemblies 13 are located in the module placement slot 11, and several welding modules 12 are fixed between the two sets of top block fixing assemblies 13.

[0037] The working principle and beneficial effects of the above technical solution are as follows:

[0038] This utility model discloses a multi-compatible welding fixture for a stacking welding machine. Several welding modules 12 can be flexibly installed in the module placement slot 11 and fixed by the top block fixing component 13. The number of welding modules 12 can be specially adapted according to different types of cell sizes. When it is necessary to handle different types of cells with multiple busbars (125-260mm), only the top block fixing component 13 needs to be removed, and welding modules 12 can be added or removed. This utility model provides an improved multi-compatible welding fixture for a stacking welding machine. It is made of a material with uniform heating and has an extended design. When performing welding for different types of cells with multiple busbars (TOPCon / HJT / XBC), there is no need to disassemble the entire machine; only welding modules 12 need to be added or removed. This solves the problem of incompatibility of the fixture when switching between different types of cells with multiple busbars, which previously required the entire stacking welding fixture to be replaced.

[0039] In one embodiment, a scale line 14 is provided on the strip support plate 10. The scale line 14 is set against the groove end of the module placement groove 11 and is used to measure the position information of the welding module 12.

[0040] The beneficial effects of the above technical solution are as follows:

[0041] The setting of scale line 14 facilitates precise positioning when changing the welding module 12.

[0042] In one embodiment, the welding module 12 includes wings 15 facing each other on its side ends, the wings 15 being snapped into the module placement slot 11.

[0043] The beneficial effects of the above technical solution are as follows:

[0044] With the wing 15 in place, the welding module 12 slides only within the module placement slot 11.

[0045] In one embodiment, the two ends of the module placement slot 11 are open to facilitate the assembly and disassembly of the welding module 12.

[0046] The beneficial effects of the above technical solution are as follows:

[0047] The open design facilitates the assembly and disassembly of the welding module 12 within the module placement slot 11.

[0048] In one embodiment, the top block fixing assembly 13 includes:

[0049] The fixed top block 16 is slidably installed in the module placement slot 11, and the two wings 25 are distributed opposite to each other on the side ends of the fixed top block 16.

[0050] Mounting screw hole 17 is provided on the fixed top block 16, and fixing screw 18 is screwed into the mounting screw hole 17;

[0051] Bottom sliding groove 19 is formed at the bottom end of the module placement groove 11. The bottom end of the fixed top block 16 is slidably connected to the bottom sliding groove 19. The bottom sliding groove 19 has fixing holes 20 evenly distributed to facilitate fixing the strip support plate 10 to the machine base.

[0052] The working principle and beneficial effects of the above technical solution are as follows:

[0053] When changing to a different type of multi-busbar solar cell, simply add or remove the welding module 12. The welding module 12 is then installed in the module placement slot 11. Next, the fixing top block 16 is installed in the module placement slot 11. After the two fixing top blocks 16 limit the welding module 12, the fixing screw 18 is screwed into the mounting screw hole 17. The fixing screw 18 rests against the bottom sliding groove 19, thereby completing the fixing of the fixing top block 16.

[0054] like Figure 7 , Figure 8 As shown, as an optional embodiment, a one-way clamping assembly 21 is also installed at the bottom end of the bottom sliding groove 19. The one-way clamping assembly 21 is located between adjacent fixing holes 20. The one-way clamping assembly 21 includes a spring plate 22. The middle of the spring plate 22 is provided with a semi-elliptical protrusion and protrudes from the groove opening end of the bottom sliding groove 19. Inclined holes 23 are provided at both ends of the spring plate 22. The far end of the inclined hole 23 is located away from the middle of the spring plate 22, and the near end of the inclined hole 23 is located away from the middle of the spring plate 22. The fixing block 24 is slidably connected in the inclined hole 23. The fixing block 24 is installed at the bottom end of the bottom sliding groove 19. In the initial state of the spring plate 22, the fixing block 24 is located at the far end of the inclined hole 23.

[0055] The working principle and beneficial effects of the above technical solution are as follows:

[0056] The welding module 12 slides into the module placement groove 11 from one end. Each time the welding module 12 passes a spring plate 22, because the middle of the spring plate 22 protrudes from the opening of the bottom sliding groove 19, the bottom end of the welding module 12 moves along with the spring plate 22. With the cooperation of the inclined hole 23 and the fixing block 24, the fixing block 24, located at the far end of the inclined hole 23, slides towards the near end of the inclined hole 23, stretching the spring plate 22. The middle protrusion of the spring plate 22 then concaves, allowing the welding module 12 to pass smoothly through the spring plate 22. The middle protrusion of the spring plate 22 applies force to the bottom end of the welding module 12. After the bottom end of the welding module 12 leaves the middle protrusion of the spring plate 22, the middle of the spring plate 22 returns to its semi-elliptical protrusion position. The spring plate 22 serves two purposes: firstly, it helps to limit the welding module 12, preventing it from sliding out completely during disassembly and replacement; secondly, it enables unidirectional limiting, ensuring that the welding module 12 can only slide into the module placement slot 11 from one end and slide out from the other end, thus limiting the sliding direction of the module placement slot 11 and facilitating disassembly and replacement by operators.

[0057] In one embodiment, the two ends of the spring sheet 22 are attached to the bottom end of the bottom sliding groove 19.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
