Welding device and welding method for single-side welded dense-grid solar cell string

Abstract

The invention provides a welding device for a single-side welded dense-grid solar cell string. The welding device is used for welding the cell string consisting of N dense-grid single-side cells, and comprises a welding table for placing welding strips and the cells at the same time, a bearing table for fixing the welding table, a base for mounting the bearing table and welding head assembly which is located above the welding table and moves up and down, wherein the cells are arranged on the upper surface of the welding table, and the welding strips are arranged below the cells; in addition, the invention further provides a welding method for welding the single-side welded dense-grid solar cell string through the welding device; and welding of the whole single-side welded dense-grid solar cell string can be achieved.

Description

technical field [0001] The present invention relates to the field of one-sided welding dense grid solar cell string welding, in particular to a single-sided welding dense grid solar cell string welding device, and also relates to a single-sided welding dense grid solar cell string welding method . Background technique [0002] In the prior art, the Chinese patent with application number CN201511007317.9 discloses an infrared heating welding device, which is mainly used for welding double-sided solar cells, and its main feature is that it is used to heat cells and ribbons The infrared heating tube is set in the platform where the battery is placed, and the back ribbon, the battery and the front ribbon are arranged on the platform at one time. There is a pressure pin on the upper part of the platform, which acts on the front ribbon, and the back ribbon is controlled by the platform. The reaction force ensures that the battery sheet is bonded to the front and back ribbons at t...

[0002] In the prior art, the Chinese patent with application number CN201511007317.9 discloses an infrared heating welding device, which is mainly used for welding double-sided solar cells, and its main feature is that it is used to heat cells and ribbons The infrared heating tube is set in the platform where the battery is placed, and the back ribbon, the battery and the front ribbon are arranged on the platform at one time. There is a pressure pin on the upper part of the platform, which acts on the front ribbon, and the back ribbon is controlled by the platform. The reaction force ensures that the battery sheet is attached to the front and back ribbons at the same time, but for the single-sided dense grid battery string, there is no corresponding welding method and welding device developed yet.
