[0045] A photovoltaic panel junction box welding control method in the present application includes:

[0046] When starting, the first motor 106 of the support assembly 1 is driven to make the first screw rod 202 drive the first slider 203 to move, and the third motor 507 is started to drive the second screw rod 302 of the first horizontal moving assembly 3 through the driving mechanism 5 to move the support column 304, completing the positioning preparation of the welding area;

[0047] During loading and unloading, the third motor 507 of the synchronous assembly 4 drives the synchronous belt 402 to drive the movable frame 606 of the alternate feeding mechanism 6, and the internal guide rod 607 and other structures thereof cooperate with the roller 6012 and the strip plate 6011 to realize the alternate feeding of the junction box body 1001, and the supporting assembly 7 and the alternate feeding mechanism 6 move synchronously to support the junction box body 1001;

[0048] When the welding position is adjusted, the third screw rod 802 of the second horizontal moving assembly 8 is controlled to rotate to drive the spot welding assembly 9 to move and align with the pin 1004;

[0049] When welding is performed, after the spot welding assembly 9 is in place, the electric telescopic rod 903 is started to make the spot welding needle 907 drop to contact the pin 1004, and at the same time, the viewfinder camera 906 and the light ring 905 are turned on to monitor and ensure the welding quality. After completing one welding, the loading and unloading and welding steps are repeated until the processing is completed.

[0050] Specifically: as the basic framework of the equipment, the support assembly 1 provides a stable installation platform for other components through structures such as a base 101, a first support plate 102, a second support plate 103, a third support plate 104 and a fourth support plate 107. The first motor 106 is located on the first fixed plate 105 and is connected to the first screw rod 202 through the third support plate 104. When the first motor 106 is started, it drives the first screw rod 202 to rotate, and then drives the first slider 203 to move horizontally in the first guide frame 201 through a threaded connection. The first horizontal movement assembly 3 is composed of two second guide frames 301, two second screw rods 302 and two second sliders 303. The two second screw rods 302 are respectively rotatably sleeved on the two second guide frames through bearings. The second guide frame 301 has two second sliders 303, and the second sliders 303 are respectively threadedly sleeved on the two second screw rods 302. When the second screw rod 302 rotates, the second slider 303 will move horizontally along the second guide frame 301. The support column 304 is fixedly connected to the second slider 303. Therefore, with the movement of the second slider 303, the support column 304 and the second horizontal movement component 8 and the spot welding component 9 thereon will also achieve horizontal movement. This design ensures that the welding head can be flexibly and accurately moved to the desired position in the horizontal direction. The synchronous component 4 realizes the synchronous rotation of the two second screw rods 302 through multiple tensioning wheels 401 and synchronous belts 402. The driving mechanism 5 includes a second fixed plate 501, a first driving wheel 502, a second driving wheel 503, Two transmission wheels 504, a first transmission belt 505 and a second transmission belt 506, and a third motor 507 drive the second driving wheel 503 to rotate, and then drive one transmission wheel 504 to rotate through the second transmission belt 506. At the same time, the first driving wheel 502 drives another transmission wheel 504 to rotate through the first transmission belt 505. The two transmission wheels 504 are respectively fixedly connected to one end of the two second screw rods 302. Therefore, the two second screw rods 302 will achieve synchronous rotation, thereby ensuring that the two second sliders 303 and the supporting columns 304 thereon can move horizontally synchronously. The mechanism drives the first connecting block 609 and the movable frame 606 to move through the circular motion of the synchronous belt 402. The movable frame 606 is internally provided with a guide rod 607 and a limit bar 608. Sliding in the limiting groove 604 realizes alternate loading. The arrangement of the roller 6012 and the strip plate 6011 ensures the stability and accuracy of the junction box body 1001 during the alternate loading process. The supporting assembly 7 supports the junction box body 1001 through the second guide rail 701, the second guide sleeve 703, the movable plate 704 and other structures. The movable plate 704 realizes synchronous movement with the alternate loading mechanism 6 through the sliding of the second guide sleeve 703 on the second guide rail 701. The storage holes 707 on the alternate plate 702 and the movable plate 704 are used to support multiple junction box bodies 1001 to ensure stability and position accuracy during welding. The second horizontal moving assembly 8 is composed of a third guide frame 801, a third screw rod 802 and a third slider 803.The third screw rod 802 is rotatably sleeved in the third guide frame 801 through a bearing, and the third slider 803 is threadedly sleeved on the third screw rod 802. When the third screw rod 802 rotates, the third slider 803 will move horizontally along the third guide frame 801. This design ensures that the spot welding assembly 9 can be flexibly moved to the desired position in the horizontal direction. The spot welding assembly 9 includes a docking piece 901, a lower support piece 902, an electric telescopic rod 903, a connecting piece 904, a light ring 905, a viewfinder camera 906 and a spot welding needle 907. When the third slider 803 moves to the desired position, the electric telescopic rod 903 drives the connecting piece 904 and the spot welding needle 907 to descend, and contact with the pin 1004 in the junction box body 1001 to complete the welding. The viewfinder camera 906 is used to monitor the welding position in real time to ensure the accuracy and quality of welding. The light ring 905 provides sufficient light to ensure that the viewfinder camera 906 can clearly capture the welding area.
