[0056] The working principle of the present invention:

[0057] As Figure 1 shown, the arrow direction is the conveying direction of the feeding belt unit 1, that is, the conveying direction of the product A to be processed. In this embodiment, the feeding assembly is composed of multiple feeding belt units 1. The product A to be processed includes the conductive wires and busbars of the stacked grid assembly. Multiple products A to be processed can be conveyed by the feeding belt unit 1. After passing through the lifting frame 3, the lifting unit 2 can be controlled to drive the lifting frame 3 to lift and lower to cache the product A corresponding to the buffer bar 4; the product A that does not need to be cached passes through the longitudinal adjustment unit and the transverse adjustment unit of the adjustment mechanism to adjust the height, width, and length positions.

[0058] The to-be-processed product A after being adjusted by the adjustment mechanism is first positioned by the rough positioning mechanism 9 for the first time. After the first positioning, it is then positioned by the fine positioning mechanism 10 for the second time. Among them, from the position of the first rough positioning to the position of the second fine positioning, a conversion mechanism is required to realize the conversion of the working station of the to-be-processed product A. That is, the conversion suction cup 18 of the conversion mechanism transfers the to-be-processed product A corresponding to the rough positioning mechanism 9 to the feeding tray 20 corresponding to the fine positioning mechanism 10. Feeding trays 20 are provided at the fine positioning station, welding station, rough cutting station, and fine cutting station on the turntable, that is, four feeding trays 20. The fine positioning station corresponds to the fine positioning mechanism 10, the welding station corresponds to the welding mechanism 11, the rough cutting station corresponds to the rough cutting mechanism 12, and the fine cutting station corresponds to the fine cutting mechanism 13. The welding structure is a laser welding mechanism 11, and both the rough cutting mechanism 12 and the fine cutting mechanism 13 are laser cutting mechanisms. The laser beam is used to perform rough cutting and fine cutting on the to-be-processed product A after welding. After the process corresponding to each station is completed, the turntable is rotated to realize the switching of the next station for processing. The finished product after the four processes is transferred to the feeding belt unit 1 corresponding to the first post-weld inspection unit 14 through the switching mechanism to realize the first post-weld inspection process of the finished product. After being inspected by the first post-weld inspection unit 14, the finished product will be further inspected for the second time, that is, inspected by the second post-weld inspection unit 15. After the to-be-processed product A is placed on the corresponding feeding tray 20, in this embodiment, the rough positioning mechanism 9 includes one or two rough positioning cameras, and the fine positioning mechanism 10 is provided with four fine positioning cameras to perform fine positioning on the to-be-processed product A. After fine positioning, the turntable rotates, so that the to-be-processed product A after fine positioning realizes the welding process, and in the rotation direction, the welding, rough cutting, and fine cutting processes are carried out in sequence;

[0059] In this embodiment, the first post-weld inspection unit 14 includes two post-weld inspection cameras, and the second post-weld inspection unit 15 includes four post-weld inspection cameras; after being inspected by the first post-weld inspection unit 14 and the second post-weld inspection unit 15, the feeding Y-axis moving unit 24 can be controlled to cause the feeding suction cup 23 to move in the Y-axis direction, and the feeding Z-axis moving unit 25 can be controlled to cause the feeding suction cup 23 to move in the Z-axis direction to move the unqualified finished products to the NG material box 26. In this embodiment, the conversion mechanism is provided with two conversion suction cups 18. When the conversion X-axis moving mechanism 16 is started, the two conversion suction cups 18 can be controlled to work simultaneously, that is, to load the material (place the to-be-processed product A) on one feeding tray 20 and unload the products (finished products) on the adjacent other feeding tray 20 at the same time, improving the overall processing efficiency and enhancing the coherence of the overall equipment connection. In this embodiment, the dust removal air knife 21 can remove and suck pollutants such as smoke, dust particles, and impurities generated by the welding mechanism 11, rough cutting mechanism 12, and fine cutting mechanism 13, and the dust removal enclosure 22 can prevent the generated pollutants from flying.

[0060] The feeding belt unit 1 can be provided with a fixture unit 19 to fixedly convey the product A to be processed or the finished product, improving the stability of conveying, processing, positioning and detection and enhancing the processing accuracy.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
