Description

Technical Field

[0001] The utility model relates to the technical field of soldering mechanical equipment, in particular to a photovoltaic equipment junction box repair welding machine. Background Art

[0002] A repair welding machine is a machine that can release welding energy in an extremely small area (<1mm2) in an instant (ms level) to completely fuse the repair material to the workpiece. The workpiece as a whole generates very little heat, so it can avoid the shortcomings of traditional welding such as deformation, cracks, and discoloration. It is particularly suitable for repairing delicate workpieces and workpieces that cannot be welded at high temperatures. In the field of repairing small defects, cold welding machines and mold repair machines are also called repair welding machines.

[0003] The photovoltaic equipment junction box repair welding machine is a device that uses a welding machine and a tin bar to cut and feed materials to weld the busbars of the junction box. There are some limitations and problems in the traditional junction box manufacturing method, which are mainly manifested in the low quality of the welding of the busbars of the junction box. The main reason for the low welding quality is that the welding position is not accurately judged, and the solder joints of the circuit board of the junction box are small. The existing junction box positioning adopts mechanical positioning, the junction box is clamped in a fixed position as a whole, and then welded through the welding head. First, the mechanical correction and centering are prone to errors, and this error is a welding error for small solder joints. Second, the solder joint positions of the junction box are not completely consistent when the circuit board is made, and small deviations will occur. This small deviation will also cause welding errors. Since there is no buffer structure on the welding head and a hard connection is adopted, the above-mentioned inaccurate welding positioning will also cause the welding head to be too close to the circuit board, causing the welding head to hard contact with the circuit board and damage the whole. Therefore, it is necessary to design a photovoltaic equipment junction box repair welding machine to solve the problem of poor welding quality and even welding errors caused by inaccurate positioning of the existing junction box repair welding machine.

The welding head 1.1 is installed on the buffer structure to avoid the welding head 1.1 from hard contact with the junction box circuit board, causing damage to the circuit board, and improve the success rate of repair welding.
