Description

Convenient stringer is dismantled to backing plate

Technical Field

The application relates to the technical field of series welding machines, in particular to a series welding machine with a backing plate convenient to disassemble.

Background

The series welding machine is important equipment for producing solar cells in the photovoltaic industry, and can precisely weld monocrystalline silicon and polycrystalline silicon cells with a welding strip with a conductive function. Generally, be provided with many main grid lines on monocrystalline silicon, the polycrystalline silicon solar cell piece, main grid line is also called silver thick liquid lead wire, mainly makes by silver thick liquid, has good electrically conductive effect, welds the area and passes through the stringer welding on main grid line, and specific welding mode is: and after the welding strip is aligned with the main grid line, the welding strip is welded on the main grid line in an infrared high-temperature hot-pressing mode.

In a heating welding workstation of a series welding machine, a heating backing plate is generally needed when a main grid line on a solar cell is welded with a welding strip. During welding, the solar cell is conveyed to the heating base plate by the conveying steel belt, and the heating base plate adsorbs the cell on the table top of the heating station through the vacuumizing device. The existence of heating backing plate provides the protection for the warm table on the one hand, and on the other hand makes the heat when welding disperse evenly on solar cell panel, is favorable to promoting the welding effect between solder strip and the main grid line for solder strip and main grid line zonulae occludens ensure electrically conductive effect.

In view of the above-mentioned related art, the inventor believes that smoothness is reduced due to friction loss generated on the surface of the heating pad plate caused by long-term friction of the solar cell plate during use, thereby causing the stability of the solar cell plate placed on the heating pad plate to be poor; on the other hand, the heating backing plate is affected by high heat of the heating table for a long time, the uniformity of heat dispersion of the heating backing plate is weakened, the uniformity of heat dispersion is reduced during welding, and the welding tightness of the welding strip and the main grid line is reduced due to the problems. Currently, there is a need for a heating backing plate that is easy to remove and replace to ensure that the solder strip and the bus bar are always well connected.
