Product Introduction:

1. Overview

This equipment is used to automatically series-weld solar cells with 5, 6, 9, 10, 11, 12, and 20 busbars into cell strings according to set parameters. It adopts infrared welding technology, a Teflon conveyor belt transmission mechanism, a solder bath immersion supply system, and automatic cell feeding, positioning, and belt pulling. After welding, the cell strings are automatically collected.

2 Features

- Highly compatible with solar cells of various specifications and wide band sizes, including 5, 6, 9, 10, 11, 12, and 20 busbars.

- High degree of automation, safe and reliable operation, easy to use, stable operation, and low noise.

- The system can automatically adjust the welding actions based on the set number of cells in the string to ensure the output cell strings meet the required number of cells.

- Good electrical conductivity of the solar cells after welding.

- Short welding time, energy-efficient, and high fusion strength.
