[0002] The development of photovoltaic technology has driven the continuous growth of industries related to solar cells, and the demand for solar energy equipment is also increasing.

[0003] In the production process of solar modules, solar cells need to be welded into strings. Solar cell string welding machines are used to weld the tested and intact cells into strings using welding strips, and to classify and collect the welded strings. They are widely used in cell manufacturing.

[0004] Because some of the welding strips are filamentous, they are prone to deviating when welding multiple strips, making it impossible to guarantee the welding quality. Utility Model Content

[0029] This application relates to a welding strip clamping mesh assembly for a string welding machine, which will be explained in detail below through specific embodiments.

[0030] A wire mesh pressing assembly for a wire mesh welding machine includes:

[0031] A pressing part 1, and a connecting part 2 adapted to the pressing part 1;

[0032] The pressing section 1 includes a first pressing mesh 11 and a second pressing mesh 12 arranged side by side.

[0033] Both the first pressing mesh 11 and the second pressing mesh 12 include a pressing mesh frame 121 and multiple pressing heads 122 disposed on the pressing mesh frame 121;

[0034] The pressure frame 121 has multiple connecting column slots 124;

[0035] The connecting part 2 includes a connecting frame 23 and a plurality of connecting columns 25 disposed on the connecting frame 23, wherein the connecting columns 25 are adapted to the connecting column groove 124;

[0036] A partition column 26 is provided between the multiple sets of connecting columns;

[0037] This utility model designs a pressing mesh part 1, which uses a pressing head 122 to fix the welding strip and the battery cell relative to each other, thus preventing the welding strip from shifting during the welding of the battery cell. At the same time, the pressing mesh part 1 is designed to be detachable, and the first pressing mesh 11 and the second pressing mesh 12 are connected by the connecting part 2, thereby making it suitable for welding battery cells and welding strips of more sizes.

[0038] When the first pressure mesh 11 and the second pressure mesh 12 are used alone and their size is insufficient, the first pressure mesh 11 and the second pressure mesh 12 are combined to increase the size and complete the pressing of the welding strip.

[0039] When the combined size of the first pressure mesh 11 and the second pressure mesh 12 is too large, the first pressure mesh 11 and the second pressure mesh 12 are separated, and the first pressure mesh 11 or the second pressure mesh 12 is used alone to complete the pressing of the welding strip.

[0040] The dimensions of the first pressure mesh 11 and the second pressure mesh 12 in the parallel direction with the connecting frame 23 may be different or the same, while the dimensions in the perpendicular direction with the connecting frame 23 may be the same. The reason for this is that the length of the battery cells when placing the solder strip varies (i.e., the dimension in the parallel direction with the connecting frame 23), but the width is the same (i.e., the dimension in the perpendicular direction with the connecting frame 23).

[0041] The attached diagram illustrates an example where the dimensions of the first pressure mesh 11 and the second pressure mesh 12 are inconsistent in the direction parallel to the connecting frame 23.

[0042] The connecting frame 23 is provided with stop blocks 24 at both ends.

[0043] Through holes are provided on the stop block 24, the multiple sets of connecting columns 25 and the partition column 26.

[0044] The pressing frame 121 has a through hole 125, which penetrates the pressing frame 121 and multiple connecting column grooves 124.

[0045] A rod 21 is adapted to be installed in the through hole and through hole 125. Both ends of the rod 21 are threaded, and a knob 22 is provided at either end of the rod 21.

[0046] The through hole of the stop block 24 has a threaded groove that matches the thread.

[0047] The end of the pressure frame 121 is provided with an adsorption magnetic block 123.

[0048] A spring is provided between the pressure frame 121 and the pressure head 122. The spring design provides a buffering force between the pressure head 122 and the welding strip, preventing the pressure head 122 from damaging the welding strip and the battery cells.

[0049] Working principle description: During operation, the connecting column 25 is inserted into the connecting column groove 124, and the rod 21 is inserted into the through hole 125 and the through hole. The threaded part on the rod 21 is screwed into the threaded groove by the knob 22, thus completing the combination of the first pressure mesh 11 and the second pressure mesh 12.

[0050] After assembly, the magnetic block 123 can be attracted by the magnetic suction robot arm, and the assembled first pressure mesh 11 and second pressure mesh 12 can be placed on the battery cell containing the solder ribbon to complete the fixation of the solder ribbon.

[0051] When the pressure section 1 presses down on the welding strip, the welding strip is fixed by the pressure head 122.

[0052] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
