Function: Adopt the method of separating the cell string from the glass, and grab the cell string in the air, then to interconnected solder the head, middle and tail bus bar of the middle wire edition module at a certain height. It has the function of rolling bus belt supply, upward bending U, L-shaped lead wire and U, L-shaped bus end punching function.
The raw material specification
Cell specification:
Standard optional from 166/182/210 mm cell), the main busbar distance is provided by the customer.
(It can be upgraded to other different cell types with compensation. The change of the main busbar of the same size cell needs to be replaced, and the soldering head and base plate need to be replaced for other 156mm-170mm, 180mm, 185mm, 210mm batteries, and other hardware needs to be adjusted.)
