Ejector pin structure of laminating machine

Abstract

The invention relates to the technical field of solar battery cell encapsulation, particularly to an ejector pin structure of a laminating machine. The laminating machine comprises a heating plate, wherein a guide hole is formed in the heating plate; the upper surface of the heating plate is a plane. The ejector pin structure comprises an ejector pin body matched with the guide hole and a platform covering the top of the ejector pin body, wherein the upper surface the platform is a plane; the ejector pin body is inserted in the guide hole; a sunken part matched with the platform is arranged at the part, right below the platform, of the heating plate; when the lower surface of the platform is in contact with the bottom surface of the sunken part, the upper surface of the platform and the upper surface of the heating plate are level. According to the ejector pin structure of the laminating machine provided by the invention, the materials of the ejector pin body, the platform and the heating plate are the same, so that consistency of heat transfer among the ejector pin part and other parts of the heating plate is guaranteed when the heating plate is heated; the platform is added at the top of the ejector pin body, so that pieces to be subjected to lamination are uniformly heated when the laminating machine is heated, consistency of EVA crosslinking degree in the pieces to be subjected to lamination is guaranteed, and the properties of a solar component are guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar cell chip packaging, in particular to a thimble structure of a laminating machine. Background technique [0002] Because the output power of a single cell is too small to meet the conventional electricity demand, it needs to be packaged into components to increase its output power. Encapsulation is a key step in the production of solar cells. Without a good encapsulation process, even the best cells cannot produce good modules. The packaging of the battery can not only ensure the life of the battery, but also enhance the resistance of the battery. At present, lamination machines are widely used in solar cell module packaging equipment, which is an important equipment for manufacturing solar cell modules. The EVA, solar cells, tempered glass, and back film (TPT, PET, etc.) are pressed into a rigid whole by a laminator under high temperature and vacuum conditions. The lamination process is a key st...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the thimble of the traditional laminator is a circular arc top, there will be a certain gap between the thimble and the laminate, and the cross-linking degree of the thimble after the EVA process is easily caused during the heating process. For the problem of inconsistency with other parts, we now provide a thimble structure of the laminator that can make the parts to be laminated evenly heated
