[0036] In an optional embodiment of the present invention, the fixing member 8 is provided with an inclined surface, and a pressure rod 28 is rotatably connected to the component plate 15 via a rotating shaft 29.

The inclined surface on the fixing member 8 is used to trigger an automatic water squeezing action, causing the upper elastic cleaning layer 24 and the lower elastic cleaning layer 22 to be squeezed, thereby enhancing the water discharge efficiency.

[0037] In an optional embodiment of the present invention, the thickness detection component includes two laser rangefinders 27, both of which are fixedly mounted on the component plate 15. The two laser rangefinders 27 are used for non-contact measurement of the thickness at the welded ends of the flexible copper busbar, improving the consistency of the finished product and the ability to monitor welding quality.

[0038] According to an optional embodiment of the present invention, a first extension plate 26 and a second extension plate 32 are fixedly connected to the component plate 15, the upper cleaning member 23 is connected to the first elastic member 25 and the first extension plate 26, and the wedge-shaped transmission block 30 is connected to the second elastic member 31 and the second extension plate 32.

[0039] In an optional embodiment of the present invention, a liquid collection tank 33 is detachably connected to the top wall of the L-shaped base 41, and the liquid collection tank 33 is located below the nozzle 19. The liquid collection tank 33 can recycle clean water, which is energy-saving and environmentally friendly.

[0040] In an optional embodiment of the present invention, the lower elastic cleaning layer 22 is detachably connected to the lower cleaning member 21, and the upper elastic cleaning layer 24 is detachably connected to the upper cleaning member 23, wherein both the lower elastic cleaning layer 22 and the upper elastic cleaning layer 24 are sponge layers.

[0041] Working principle:

[0042] Place two or more copper sheets 14 into the storage cavity 12, and the electric slider 3 moves to the left, thereby driving the conveyor rod 4 to push the two or more copper sheets 14 to the top wall of the worktable 34.

[0043] The height of the connecting channel 13 is the same as the height of the conveyor rod 4. Together, they determine the number of copper sheets 14 that are pushed out. The copper sheets 14 in the storage cavity 12 are supported by the top wall of the conveyor rod 4 and will not move temporarily.

[0044] The lower end of the second clamping plate 10 is lower than the lower end of the first clamping plate 9. When the copper sheet 14 abuts against the right wall of the second clamping plate 10, the cylinder 7 controls the fixing part 8 to move down and press the copper sheet 14, activating the electromagnet 42. The electromagnet 42 generates a magnetic repulsion force on the permanent magnet 47, thereby causing the permanent magnet 47 and the motor base 44 to overcome the elastic force of the third elastic part 43 and move upward. The third gear 46 switches from meshing with the second gear 40 to meshing with the first gear 37, activating the motor body 45. The motor body 45 drives the third gear 46, the first gear 37, and the screw 36 to rotate, thereby causing the first clamping plate 9 to move to the left to clamp the copper sheet 14. The electromagnet 42 and the motor body 45 are de-energized, and the motor base 44 is under gravity. The action moves the third gear 46 downward, causing it to re-engage with the second gear 40. The transmission rod 4 and the fixing part 8 continue to move to the left, thereby moving the copper sheet 14 between the lower welding part 16 and the upper welding part 17. The welding device 18 drives the upper welding part 17 to press down on the copper sheet 14. The upper welding part 17 and the lower welding part 16 weld one end of the copper sheet 14. The upper welding part 17 moves upward, and the motor body 45 is turned on, driving the third gear 46, the second gear 40, the worm gear 39, the worm 38, and the fixing part 8 to rotate, thereby causing the copper sheet 14 to rotate 180 degrees. The upper welding part 17 moves downward, and the upper welding part 17 and the lower welding part 16 weld the other end of the copper sheet 14 to form a soft copper busbar.

[0045] The surface of the high-temperature soft copper busbar may emit radiation light similar to the laser wavelength, which may interfere with the detection of reflected light by the laser rangefinder 27. Furthermore, the high temperature may cause accidental injury to personnel when the soft copper busbar is removed. Therefore, it is necessary to cool the soft copper busbar.

[0046] The fixing component 8 drives the soft copper busbar to move to the left, and the nozzle 19 sprays clean water to cool one end of the soft copper busbar. The clean water falls into the liquid collection tank 33 for recycling to prevent resource waste. The fixing component 8 drives the soft copper busbar to rotate 180 degrees.

[0047] Water will form a film or droplets on the surface of the soft copper busbar, causing the laser beam of the subsequent laser rangefinder 27 to be refracted or scattered, changing the propagation direction and intensity of the laser, thereby affecting the laser rangefinder 27's reception of reflected light and affecting the detection results.

[0048] During the rotation of the soft copper busbar, one end passes between the lower elastic cleaning layer 22 and the upper elastic cleaning layer 24. The lower elastic cleaning layer 22 and the upper elastic cleaning layer 24 wipe and clean one end of the soft copper busbar to prevent water from affecting subsequent thickness testing. The nozzle 19 sprays water to cool the other end of the soft copper busbar. The fixing part 8 drives the soft copper busbar to rotate 180 degrees, and the lower elastic cleaning layer 22 and the upper elastic cleaning layer 24 wipe and clean the other end of the soft copper busbar.

[0049] It is necessary to check whether the thickness of the weld joints at both ends of the soft copper busbar meets the standard. The fixing part 8 moves the soft copper busbar to the left, and one end of the soft copper busbar moves between the two laser rangefinders 27. The thickness of the weld joint at one end of the soft copper busbar can be determined by the measurement of the two laser rangefinders 27. The fixing part 8 rotates the soft copper busbar 180 degrees, and the other end of the soft copper busbar moves between the two laser rangefinders 27. The thickness of the weld joint at the other end of the soft copper busbar can be determined by the measurement of the two laser rangefinders 27, and whether it meets the standard.

[0050] The fixing member 8 drives the soft copper busbar to move to the left. The inclined surface of the fixing member 8 pushes the wedge-shaped transmission block 30 to move upward against the elastic force of the second elastic member 31. The wedge-shaped transmission block 30 pushes the pressure rod 28 to rotate clockwise around the rotating shaft 29, so that the rotating shaft 29 presses the upper cleaning member 23. The upper elastic cleaning layer 24 and the lower elastic cleaning layer 22 abut against each other and squeeze each other, squeezing the water in the upper elastic cleaning layer 24 and the lower elastic cleaning layer 22 into the liquid collection tank 33, so as to facilitate wiping and cleaning the next soft copper busbar.

[0051] Reactivating electromagnet 42 and motor body 45 allows the first clamping plate 9 to move to the right, releasing the clamp on the soft copper busbar, thus removing the soft copper busbar and completing the welding operation.

[0052] Subsequently, the conveyor rod 4 moves to the right and resets, releasing its support for the copper sheet 14 in the storage cavity 12. The copper sheet 14 in the storage cavity 12 falls down to abut against the bottom wall of the storage cavity 12, so that it can be pushed out by the conveyor rod 4 for welding.

[0053] This invention can automatically perform quantitative feeding, positioning, clamping, welding, flipping, cleaning, wiping, and inspection of copper sheets 14 throughout the entire process, effectively reducing manual intervention and improving production efficiency and yield.

[0054] The gripping component achieves automatic clamping, positioning, and release through electromagnetic control, gear transmission, and elastic structure. The structure is stable and the action is precise, avoiding welding offset due to inaccurate positioning. There is no need for manual stacking and clamping of copper sheet 14.

[0055] The innovative rotating structure allows the copper sheet 14 to rotate automatically, and the welding components can quickly complete the double-end welding without the need for manual reversal, thus preventing burns to personnel.

[0056] The cooling component, in conjunction with the wiping component, can automatically cool and clean the soft copper busbar, preventing high temperatures from affecting the subsequent thickness detection component and preventing water refraction from affecting the subsequent thickness detection component.

[0057] The laser rangefinder 27 of the thickness detection component enables real-time detection of the thickness at the weld joint, which can detect welding deviations in real time and adjust process parameters to improve quality traceability and reliability.

[0058] By setting an inclined structure on the fixing member 8, and cooperating with the wedge-shaped transmission block 30, pressure rod 28, rotating shaft 29 and first elastic member 25, the automatic pressing function of the upper cleaning member 23 is realized, and the moisture of the upper elastic cleaning layer 24 and the lower elastic cleaning layer 22 is automatically removed, which facilitates subsequent cleaning operations.

[0059] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
