A ribbon fixed-length feeding device for a solar cell welding machine

Abstract

The invention relates to a solar cell production equipment. A welding ribbon fixed-length feeding device for a solar battery welding machine, which includes a material feeding mechanism, a cutting mechanism, and a belt pulling mechanism; along the direction of feeding the welding ribbon, the material feeding mechanism, the cutting mechanism, and the belt pulling mechanism Arranged successively, the material-clamping and sending-out mechanism corresponds to the pull belt mechanism, and the height of the clamping end is the same. The material-clamping and sending-out mechanism is used to clamp the delivered welding ribbon and keep it stretched straight. The mechanism is used to clamp one end of the welding ribbon and pull it out; the cutting mechanism is used to cut off the welding ribbon. The invention can simultaneously clamp a plurality of welding strips, with high synchronization and high efficiency; the welding strips are placed obliquely through the swing rod, which improves the precision and accuracy and avoids the rebound impact of the welding strips being directly put down.

Description

technical field [0001] The invention relates to a solar battery production equipment, in particular to a welding ribbon fixed-length 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 wel...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is: to solve the problems in the prior art that the welding ribbon is placed directly and is easy to bounce, the welding accuracy of the welding ribbon is not high, and the length control is not uniform, a welding ribbon with high cutting precision is proposed, and the welding ribbon is placed obliquely. The ends are clamped in turn, and the welding ribbon fixed-length feeding device of the solar cell welding machine is accurate.
