At the same time, the spring 44 allows the pressure block 43 to adapt to battery cells of different thicknesses, making it convenient for workers to use.

[0024] The second positioning mechanism 5 includes a second bracket 51. Two sets of symmetrically distributed support blocks 52 are fixedly installed on the lower inner surface of the second bracket 51. The two sets of support blocks 52 are fixedly connected by two support rods 53. A symmetrically distributed positioning plate 54 is movably sleeved on the outer side of the two support rods 53. A positioning block 55 is fixedly connected to the bottom of the positioning plate 54. An extension plate 56 is fixedly installed on the top of one of the positioning plates 54. A second electric push rod 57 is fixedly installed on the top of the second bracket 51. The second electric push rod 57 and the extension plate 56 are fixedly connected. The tops of both positioning plates 54 are fixed. The second bracket 51 is equipped with two toothed plates 58 arranged diagonally. A third rotating shaft 59 is rotatably mounted on the lower inner wall of the second bracket 51. A third pinion 591 is fixedly mounted at the bottom of the third rotating shaft 59. Both toothed plates 58 are meshed with the third pinion 591. A horizontal plate 592 is fixedly mounted on the outer side of the second bracket 51. An industrial camera 593 is fixedly connected to the bottom of the horizontal plate 592. The second positioning mechanism 5 is used to prevent the battery cells from shifting before welding, thereby improving welding accuracy. The industrial camera 593 can quickly detect shifted battery cells, preventing errors and omissions.

[0025] The drive mechanism 6 includes a first motor 61, a second motor 62, a third motor 63, and a fourth motor 64. The first motor 61, the second motor 62, and the third motor 63 are coaxially and fixedly connected to the first threaded rod 22, the second threaded rod 27, the first rotating shaft 31, and the second rotating shaft 32, respectively. Through the drive mechanism 6, power can be provided to the first threaded rod 22, the second threaded rod 27, the first rotating shaft 31, and the second rotating shaft 32.

[0026] Working principle: In actual use, the conveyor belt 12 is activated to move the solar cells. When the solar cells are near the second positioning mechanism 5, the industrial camera 593 takes a picture of them and analyzes their position accuracy in the background. When the photovoltaic module deviates, the second electric push rod 57 is activated, causing its output end to move the extension plate 56 towards the second electric push rod 57. At this time, the extension plate 56 moves the positioning plate 54 and the positioning block 55. The positioning plate 54 drives the third pinion 591 to rotate through the toothed plate 58. The third pinion 591 drives the other positioning plate 54 and the positioning block 55 to move through another toothed plate 58, so that the two positioning blocks 55 move towards each other, thereby positioning the solar cells. It should be noted that the conveyor belt 12 is driven by a traditional servo motor, which will not be elaborated on here. The positioned battery cell then moves to the bottom of the welding mechanism 2. The first threaded rod 22 is driven to rotate, causing the two first sliders 24 to move. The first sliders 24 move the moving plate 25. The second threaded rod 27 is driven to move the second slider 28, which in turn moves the sliding plate 29, the first electric push rod 291, the fixed plate 294, and the welding gun 295. This allows the welding gun 295 to be moved to any part of the battery cell, facilitating welding of battery cells of different sizes. The infrared emitter 293 then guides the welding gun 295 to the appropriate position. The first electric push rod 291 is activated, causing its output end to lower the fixed plate 294. At this point, the pressure block 43 contacts and positions the battery cell, preventing displacement during welding. When the pressure block 43 is under pressure, it moves the movable rod 42 inwards towards the fixed rod 41, while the spring 44 is compressed, facilitating subsequent reset of the pressure block 43. This allows for the adaptation of battery cells of different thicknesses. When the angle of the welding gun 295 needs to be adjusted, the second rotating shaft 32 is driven to rotate. The second rotating shaft 32 drives the second large gear 37 to rotate via the second small gear 34. The second large gear 37 drives the first bevel gear 38 and the second bevel gear 39 to rotate. The second bevel gear 39 drives the first bracket 392 and the welding gun 295 to rotate via the adjusting rod 391. Then, the first rotating shaft 31 is driven to rotate, which drives the rotating column 35 to rotate via the first large gear 36. The rotating column 35 drives the first bracket 392 and the welding gun 295 to rotate as a whole via the adjusting rod 391, thereby enabling the welding gun 295 to be adjusted to different angles.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
