Problems solved by technology

In this way, since the lead wire and the battery sheet are soldered, the welding point becomes a direct stress point, and the lead wire and the battery sheet will be bent and twisted, desoldered, cracked and hidden defects will be deteriorated under the action of stress, especially for ultra-thin batteries. film, this will happen even more

Abstract

The invention relates to a safety sucker of a solar cell string, which comprises a sucker frame main body and a vacuum controller, wherein the top of the sucker frame main body is connected with a vacuum generator in the vacuum controller by a pipeline. Compared with the prior art, leads and cell pieces of the invention are not stressed; the phenomena of bending and torsion deformation, sealing off, split fragments and hidden defect deterioration, caused by manual lifting movement, are avoided; the safety sucker has better safety performance; in the movement of the sucker, the cell string is safely absorbed and cannot drop off; and the operation efficiency of the safety sucker is also improved.

Description

technical field [0001] The invention relates to a sucker, in particular to a solar battery string safety sucker. Background technique [0002] In the packaging process of crystalline silicon solar cells, after the cells are welded in series to form a string (12 pieces are a string), the mobile station performs multi-string typesetting. At present, the manual movement method is basically adopted in China: the movement method of manually pulling the lead wire directly. In this way, since the lead wire and the battery sheet are soldered, the welding point becomes a direct stress point, and the lead wire and the battery sheet will be bent and twisted, desoldered, cracked and hidden defects will be deteriorated under the action of stress, especially for ultra-thin batteries. film, this will happen even more. Contents of the invention [0003] The object of the present invention is to provide a safe, reliable, and highly efficient solar cell string safety sucker in order to ov...
