Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to an integrated machine for stacked grating laser welding and cutting. Background Technology

[0002] Traditional stringing machines, used for conventional photovoltaic cells, employ grippers to place the welding ribbon onto the cell's main grid, then use infrared lamps for heating and welding. However, tandem grid modules have a large number of densely arranged conductive wires, making it impossible to use conventional stringing machines to connect the positive and negative terminals of the tandem grid cells together via conductive strips. Therefore, a novel non-contact laser welding process can be used for tandem grid modules, suitable for welding irregularly shaped conductive wires in the tandem grid cell structure.

[0056] The working principle of this utility model:

[0057] like Figure 1 As shown, the arrow indicates the conveying direction of the feeding belt unit 1, i.e., the conveying direction of the product A to be processed. In this embodiment, the feeding assembly consists 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 units 1. After passing through the lifting frame 3, the lifting frame 3 can be raised and lowered by controlling the lifting unit 2 to buffer the product A to be processed corresponding to the buffer bar 4. Products A to be processed that do not need to be buffered are adjusted in height, width, and length by the longitudinal adjustment unit and the transverse adjustment unit of the adjustment mechanism.

[0058] After adjustment by the adjustment mechanism, the product A to be processed is first positioned by the coarse positioning mechanism 9, and then positioned a second time by the fine positioning mechanism 10. A switching mechanism is needed to switch the workstation of product A from the position of the first coarse positioning to the position of the second fine positioning. Specifically, the switching suction plate 18 of the switching mechanism transfers product A from the coarse positioning mechanism 9 to the feeding plate 20 corresponding to the fine positioning mechanism 10. The turntable has four feeding plates 20: a fine positioning station, a welding station, a coarse cutting station, and a fine cutting station. The fine positioning station corresponds to the fine positioning mechanism 10, the welding station corresponds to the welding mechanism 11, and the coarse cutting station corresponds to the coarse cutting machine. Structure 12 and the fine cutting station are equipped with a fine cutting mechanism 13. The welding structure is a laser welding mechanism 11. 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 welded product A. After the corresponding process of each station is completed, the turntable will rotate to realize the switching to the next station. After the four processes are completed, the finished product (the finished product A after processing) 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 the first post-weld inspection unit 14 detects the finished product, the finished product will be further inspected a second time, that is, the second post-weld inspection unit 15 will inspect the finished product. After the product A is placed on the corresponding feeding tray 20, the rough positioning mechanism 9 in this embodiment includes one or two rough positioning cameras, and the fine positioning mechanism 10 is equipped with four fine positioning cameras to perform fine positioning of the product A. After fine positioning, the turntable rotates so that the product A after fine positioning can realize the welding process. The welding, rough cutting and fine cutting processes are performed in sequence along the rotation direction.

[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 inspection by the first post-weld inspection unit 14 and the second post-weld inspection unit 15, the unloading Y-axis moving unit 24 can be controlled to move the unloading suction cup 23 in the Y-axis direction, and the unloading Z-axis moving unit 25 can be controlled to move the unloading suction cup 23 in the Z-axis direction, so that the finished products that fail the inspection are moved to the NG material box 26. In this embodiment, the conversion mechanism is provided with two conversion suction plates 18. When the conversion X-axis moving mechanism 16 is started, the two conversion suction plates 18 can be controlled to work simultaneously, that is, to load material (place product A to be processed) onto one unloading plate 20, and simultaneously unload the product (finished product) onto the adjacent unloading plate 20, thereby improving the overall processing efficiency and enhancing the continuity of the overall equipment connection. In this embodiment, the dust removal air knife 21 can remove and suck away pollutants such as smoke, dust particles, and impurities produced by the welding mechanism 11, the rough cutting mechanism 12, and the fine cutting mechanism 13, while the dust removal enclosure 22 can prevent the pollutants produced from flying away.

[0060] The feeding belt unit 1 can be equipped with a clamping unit 19 to fix and transport the product A to be processed or the finished product, thereby improving the stability of conveying, processing, positioning and detection, and improving the processing accuracy.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
