Lamination device for solar modules and lamination encapsulation method thereof

Abstract

The present invention discloses a laminating apparatus for a solar assembly. The laminating apparatus comprises a substrate and a pressing plate; a hydraulic cylinder drives the pressing plate to move up and down, so that the substrate and the pressing plate can be pressed together; the bottom surface of the pressing plate is provided with a silica gel film; the surface of the substrate is provided with a plurality of pushing pins; a cushion is laid on the pushing pins; mounting holes are arranged formed in the substrate; the pushing pins are installed in the mounting holes through lifting rods; the bottoms of the lifting rods are provided with heat insulating sleeves; electric heating wires are arranged in the substrate; the bottoms of the mounting holes are provided with spiral oil guiding tubes; annular grooves are formed at the tops of the mounting holes; the edges of the pushing pins are provided with metal elastic sheets through first springs; the external sides of the metal elastic sheets are provided with silica gel dumping cushions; the edge of the pressing plate is provided with slide rails; a clamping block is slidingly arranged in each slide rail; each clamping block is connected with a corresponding first air cylinder; and the clamping blocks are fixedly held at the edge of the silica gel film. With the laminating apparatus of the invention adopted, defects in the prior art can be eliminated, and the heating and pressure uniformity of components in a laminating process can be improved, and the yield of products can be improved.

Description

technical field [0001] The invention relates to the technical field of production of solar cell components, in particular to a lamination device for solar components and a lamination packaging method thereof. Background technique [0002] As a new energy technology, solar cells are widely used in various fields. Among them, installing solar panels and batteries on street lamps for nighttime lighting, using the electric energy converted from solar energy during the day to provide nighttime lighting energy for street lamps, has become an environmentally friendly and energy-saving common practice. In order to improve the sealing and durability of the solar cell, it is necessary to use PVB or EVA material to package the solar cell. [0003] In prior art laminator, when laminating and encapsulating the components, in order to avoid heating up the components prematurely during the transfer process of the components, a jack is used to pre-support the components. However, this str...

Problems solved by technology

However, this structure will bring the problem of uneven heating to the component itself during the lamination and packaging process. In addition, since the silicone membrane that provides the downforce can only be installed by edge fixing, this leads to Inevitable pressure differentials between the center and edges of the

These problems will lead to problems such as air bubbles and breakage during the lamination process of the components, which will affect the product yield.
