Vacuum laminating machine heat equalizing thimble structure

Abstract

The invention relates to the technical field of photovoltaic cell packaging, and discloses a vacuum laminating machine heat equalizing thimble structure comprising a worktable, an upper case cover, asilica gel plate, a sealing ring, a battery assembly and a thimble hydraulic cylinder. A mounting groove is arranged in the top end of the worktable and at the position of the thimble hydraulic cylinder. A heat equalizing mechanism is arranged in the mounting groove. The heat equalizing mechanism comprises a circular plate formed by four identical heat equalizing plates through enclosing. A guiderail slip ring is fixedly mounted at the center of one end of the bottom of each heat equalizing plate. The heat equalizing mechanism is arranged so that the worktable transfers heat to the heat equalizing plates when the thimble hydraulic cylinder jacks up the battery assembly during the preheating stage of the electric heating plate on the worktable and the heat degree of the heat equalizing plates is basically synchronized with the surface of the worktable. Therefore, the bottom of the battery assembly can receive uniform heat transfer after the battery assembly is unloaded and the problemof uneven local heating of the battery assembly due to the existence of the thimble is fundamentally eliminated.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cell packaging, in particular to a vacuum laminator soaking thimble structure. Background technique [0002] The function of the vacuum laminator is to press multiple layers of materials together. It is often used in the packaging of solar battery packs. Its system consists of a conveying system, a heating and cooling system, and a vacuum system. Among them, the vacuum system is as follows: figure 1 The shown includes a silica gel plate 3 installed on the upper case cover 2, the silica gel plate 3 and the upper case cover 2 constitute the upper vacuum chamber, the silica gel plate 3 and the workbench 1 constitute the lower vacuum chamber, and the battery assembly 5 is placed on the workbench 1 The upper and lower vacuum chambers are vacuumed respectively through the upper vacuum chamber and the lower vacuum chamber is inflated; the upper and lower vacuum chambers are evacuated at the same tim...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use process of the existing vacuum laminator proposed in the background technology, the present invention provides a vacuum laminator uniform heating thimble structure, It has the advantage of more uniform heating of the components, and solves the problems raised in the above-mentioned background technology
