Battery piece welding machine capable of reducing insufficient welding and using method

Abstract

The invention provides a battery piece welding machine capable of reducing insufficient welding and a using method. The welding machine comprises a machine body, a connecting block is arranged in themachine body, a base plate is arranged at the top of a connecting frame, a movable block is movably connected to the middle side of the bottom of the base plate, and a connecting plate is connected tothe bottom of the movable block. A second gear is connected to one side of a toothed plate, a rotating rod penetrates through the middle of the second gear, a bearing seat is connected to one end ofa rotating rod, a rotating wheel is connected to the other end of the rotating rod, and a collecting box is installed on the side, close to the connecting block, of the machine body. According to themachine, two groups of pressing needles are arranged, and the pressing needles are in an inclined plane octagonal shape, so that compared with a traditional taper, the pressing needles in the inclinedplane octagonal shape increase the contact area between the pressing needles and a battery piece, the welding coverage area of the battery piece is more comprehensive, and the phenomenon that due tothe fact that the battery piece is too large during welding, traditional equipment can not weld the edge of the battery piece, so that the insufficient welding is generated is effectively reduced.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a cell welding machine capable of reducing false welding and a use method thereof. Background technique [0002] Cells are generally divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells are currently the fastest-developing solar cells. Its structure and production process have been finalized, and its products have been widely used in space and on the ground. This kind of solar cell uses high-purity monocrystalline silicon rods as raw materials. In order to reduce production costs, solar cells used on the ground now use solar-grade monocrystalline silicon rods. The material performance indicators have been relaxed, and some semiconductor devices can also be used. The processed head and tail materials and waste monocrystalline silicon materials are redrawn into monocrystalline silicon rods for solar cells, which ...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a cell welding machine capable of reducing false welding and its use method, which solves the problem that the waste produced by the cell welding machine in the prior art is difficult to clean up, and the welding machine is heavy and troublesome to move. Moreover, due to the limitations of itself and the equipment, the traditional tapered indenter has a limited maximum welding distance, which may easily cause the problem of false welding of the battery sheet.
