[0002] Photovoltaic diode soldering technology refers to the key technology of attaching solder sheets to the electrode or pin surfaces of photovoltaic diodes (such as bypass diodes and anti-reverse diodes in photovoltaic modules) and achieving electrical connection through a soldering process. Its main purpose is to enhance conductivity, improve soldering reliability, and meet the long-term stable operation requirements of photovoltaic modules under harsh environments such as high temperature and high current.
[0003] Current solder sheet mounting processes typically employ a dispensing method, resulting in low production efficiency. Solder sheet feeding relies on manual tray changing, which is inefficient and labor-intensive. Since multiple photovoltaic diodes need to be soldered, missed spots occur and cannot be detected promptly, leading to a low yield rate. Furthermore, different solder sheet specifications require different feeding mechanisms due to varying mounting spacing, further increasing production costs.

[0027] According to the specifications of the solder sheet, the switching motor 662 drives the opening and closing turntable 663 to rotate. The notch 669 rotates to the position of the photoelectric switch 664, which is then activated. The electric roller 668 starts, driving the bracket 661 to move along the Y-axis guide rail 667. After the distance between the suction cup units along the Y-axis increases to a suitable distance, the opening and closing turntable 663 rotates, the notch 669 moves out of the position of the photoelectric switch 664, and the electric roller 668 closes. This system can accommodate the placement of solder sheets of different specifications, reducing production costs and improving the versatility and flexibility of the equipment.
[0028] A circular vibrating feeding tray 51 conveys the solder sheet 9 to the feeding plate 52. The solder sheet 9 advances along the feeding channel 54. The Y-axis linear module 61 drives the pneumatic suction cup module 66 to move above the end of the feeding channel 54. The third Z-axis linear module 63 drives the pneumatic suction cup module 66 to descend to the solder sheet 9. The suction nozzle 670 picks up the corresponding number of solder sheets 9. The pneumatic suction cup module 66 rises and resets, then moves to the support plate 31. The pneumatic suction cup module 66 descends again, attaching the solder sheet 9 to the corresponding glue application area of the photovoltaic diode 8. After the solder sheet 9 is attached, the pneumatic suction cup module 66 rises and resets, and the photovoltaic diode 8 moves forward to below the second industrial camera 602. The second industrial camera 602 captures an image of the attached photovoltaic diode 8 and displays the image on the attachment image display screen 603. The operator checks the attached photovoltaic diode 8 to see if any solder sheets are missing based on the image. After checking and confirming that there are no missing solder sheets, the photovoltaic diode 8 is conveyed to below the discharge gripper 79. Visual inspection after the adhesive application and patch installation processes can promptly identify areas that have been missed in the application or installation process, thereby reducing the defect rate.
[0029] The fourth Z-axis linear module 75 drives the discharge gripper 79 to descend onto the support plate 31. The discharge gripper 79 grabs the photovoltaic diode 8. The discharge gripper 79 rises and resets, and moves out of the product conveyor mechanism 3 under the drive of the third belt pulley transmission mechanism 73. The rotary cylinder 77 drives the photovoltaic diode 8 to rotate 90° and then discharges the material.
[0030] The entire solder sheet placement process is fully automated, reducing manual intervention and improving production efficiency and stability.
