Hot plate uniform heating laminator suitable for solar cell assembly process

Abstract

The invention discloses a hot plate uniform heating laminator suitable for a solar cell assembly process. The laminator comprises a heating workbench and an upper cover, wherein the upper cover is formed by combining an upper box chamber, a silica gel plate and an upper chamber sealing ring in turn; the outer ring of the edge of the heating workbench is provided with a lower chamber sealing ring; a laid cell component is arranged on the working surface of the laminator; the upper cover is pressed downwards so as to firmly joint the upper chamber sealing ring on the upper cover and a lower chamber sealing ring surrounding the edge of the heating workbench and form a vacuum chamber between the upper cover and the heating workbench; the upper box chamber is arranged on the upper part of the heating workbench and forms a vacuum chamber with the heating workbench; the upper chamber sealing ring is arranged at the periphery of the silica gel plate; the lower chamber sealing ring is arranged at the periphery of the heating workbench and matched with the upper chamber sealing ring so as to seal the vacuum chamber; an electric heating device and a temperature control device are arranged in the heating workbench; the heating workbench is rectangular and is partitioned into a main heating region and an auxiliary heating region according to the horizontal rectangular surface of the heating workbench; and the auxiliary heating region encircles the main heating region.

Description

Technical field [0001] The invention relates to an equipment in the production process of solar cell components, in particular to a hot plate uniform heating laminator suitable for the solar cell assembly process. Background technique [0002] With the rapid economic development and continuous advancement of technology, the consumption and demand for energy in social life have also increased sharply. At present, most of the energy widely used by mankind is still fossil energy represented by coal and petroleum. Fossil energy has been developed so far, although its mining and use technology has been very mature, but the accompanying problems also cannot be ignored. First of all, fossil energy is a non-renewable resource, and its total storage volume must be an irreversible process of declining; secondly, fossil energy will produce a lot of pollution during the use of coal, carbon dioxide, sulfur dioxide and nitrogen-based Compounds can cause greenhouse effect and serious pollutio...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a laminator suitable for solar cell press-fitting that realizes uniform heating of the hot plate by means of electric heating. The laminator with this heating structure not only solves the problem of the existing oil heating The laminator is prone to safety hazards, and at the same time solves the problem of poor temperature uniformity caused by traditional electric heating methods, and it is difficult to achieve temperature convergence in a large area. High quality, low equipment failure rate, convenient maintenance, suitable for widespread use in my country, a large solar cell production country
