Tape cloth film welding device, method and stitch welding machine

Abstract

A tape-laying film-distributing welding device is installed on a machine frame, and adopts a welding technology of welding a battery string which is laid on a bearing plate of the machine frame in a flat manner into a battery assembly. Both ends of the battery string are provided with welding strip length reservation parts for series welding. The tape-laying film-distributing welding device is characterized by comprising a tape laying device, a film distributing device, a welding device and a control device, wherein the tape laying device, the film distributing device and the welding device are electrically connected with the control device. The embodiment of the invention further provides another kind of tape-laying film-distributing welding device, a stitch welding machine and a tape-laying film-distributing welding method.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a tape-laying cloth film welding device, a method thereof and a stitch welding machine. Background technique [0002] A solar cell module is a power generation device that is used to generate photoelectric effect and convert light energy into electrical energy when placed in sunlight. The manufacturing process of the solar cell module is that a plurality of cells used for photoelectric effect need to be welded in series to form a battery string, and then the plurality of cell strings are reconnected to form a complete circuit through a busbar, and finally a solar cell module is made. The operation of reconnecting multiple battery strings through the bus belt is as follows: arrange and place several battery strings in a certain order, weld the long welding ribbons at the first and last ends of the battery strings in series through the bus belt one by one, and finally connect the welded E...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitation of the volume of the junction box and the layout of the busbars, it is impossible to avoid contact between multiple busbars after the busbars are connected to the junction box. Insulating materials such as insulating film isolate the busbars that may be in contact with each other

In the prior art, the operation of placing insulating films layer by layer and one by one in the confluence strip access of the junction box is manual work, which has large errors in manual work, resulting in very low production efficiency and poor quality stability. In addition, manual work It is also easy to make mistakes. When the layout position deviates greatly from the specified position, it may cause a short circuit due to the contact of the bus belt, which is poor in safety.
