Lamination structure of a vacuum laminator

Abstract

The invention relates to the technical field of photovoltaic manufacturing equipment, and discloses a laminated structure of a vacuum laminating machine. The laminated structure comprises an upper cover and a silica gel plate, and an upper cavity surrounded by the upper cover and the silica gel plate, wherein a top pressing cylinder is arranged at each of the four corners of the top end of the silica gel plate; the top pressure cylinders and the silica gel plate are integrally formed; a gas guide pipe is arranged at the bottom of one side of each top pressure cylinder, and the gas guide pipe is used for communicating the interior of the top pressure cylinder with the upper cavity; one side of the top pressing cylinder is also provided with an inflating pipe; and the inflating pipe is usedfor communicating the interior of the top pressing cylinder with a vacuum system pipeline of a laminating machine. According to the laminated structure, the top pressing cylinders are additionally arranged on the inner layer of the silica gel plate, and the gas inlet diameter of the inflating pipe is set to be larger than the gas outlet caliber of the gas guide pipe, so that in the vacuumizing heating stage, the top pressing cylinders can be preferentially supported by the air inflation, and the inner top part of the upper cover is supported by the top pressing cylinders, so that the part, located below the top pressing cylinders, of the gas guide pipe preferentially presses the four corners of a solar assembly, and therefore the four corners of the toughened glass of the solar assembly are effectively prevented from tilting up.

Description

technical field [0001] The invention relates to the technical field of photovoltaic manufacturing equipment, in particular to a lamination structure of a vacuum laminator. Background technique [0002] Vacuum laminator is a mechanical device that laminates multi-layer materials under vacuum conditions. At present, in the field of solar panel manufacturing, solar cell components are divided into glass, EVA, solar cell array, EVA, TPT from bottom to top. The five-layer components are stacked together and put into the laminator. [0003] The main structure of the laminator is composed of upper and lower vacuum chambers, silica gel plates, heating systems, vacuum systems, heating control systems, control systems, etc. Lamination is generally divided into the following stages: when the component enters the laminator, the lower chamber is inflated, and the upper chamber is vacuumed; after the upper cover is closed, the lower chamber is evacuated, and the component is heated at th...
