Cell feeding device of solar cell welding machine

Abstract

The invention relates to solar cell production equipment. A cell feeding device of a solar cell welding machine comprises a bottom frame, a material frame, a material pushing cylinder, a material pushing plate, a positioning cylinder, a positioning plate, a lifting frame, a direct current motor and a lead screw assembly; the material frame is fixedly arranged on the bottom frame; the bottom frameis fixedly arranged on a frame; the lifting frame is movably matched with the bottom frame; the direct current motor and the lead screw assembly are arranged on the bottom frame; the direct current motor is connected with an input end of the lead screw assembly; an output end of the lead screw assembly is connected with the lifting frame; the material pushing plate is movably connected in the material frame; the positioning cylinder is arranged on the side of the material frame; and a telescopic end of the positioning cylinder is connected with the material pushing plate. According to the solar cell production equipment, cell pieces are stacked in solar boxes, and multiple solar boxes are stacked, so that the capacity of the solar cells is greatly improved, and the empty solar boxes can return materials automatically.

Description

technical field [0001] The invention relates to a solar battery production equipment, in particular to a battery feeding device of a solar battery welding machine. Background technique [0002] The welding of solar cells is generally divided into two steps. The first step is to weld the ribbon to the main grid of the front electrode. When welding, first coat the solder with flux and dry it, and then place the solar cell on the preheating plate Preheat to 40-50 degrees Celsius, and then place the solder ribbon on the appropriate position of the main grid line of the cell, so that the center line of the solder ribbon coincides with the center line of the main grid line, and then slide and solder along the direction of the main grid line with an electric soldering iron The whole welding process requires very precise operation and control, otherwise it is easy to cause product quality problems. The second step is to weld the battery piece with the ribbon welded in the first ste...
