Protecting die for double-glass assembly

Abstract

The invention provides a protecting die for a double-glass assembly. The protecting die comprises four thickness-adjustable protecting corners, and elastic strips which are connected between every twoadjacent protecting corners, wherein each protecting corner comprises a hollow cavity and an adjusting protecting wing; an elastic strip coiling part comprising a coiling shaft is arranged in each cavity; the coiling shafts are connected to two ends of the elastic strips which pass through first sidewalls of every two adjacent cavities; each adjusting protecting wing comprises a fixed protectingwing, and a movable protecting ring capable of adjusting the spacing relative to the fixed protecting wing; the movable protecting wings are movably connected to second sidewalls of the cavities. Theprotecting die is capable of protecting and stabilizing the double-layer glass assembly during laminating.

Description

technical field [0001] The invention belongs to the field of battery plate production, and in particular relates to four-corner protection equipment for battery plate processing. Background technique [0002] In the production process of photovoltaic double-glass modules, the lamination process is the most critical one. However, during the lamination process, the laminated silicone plate is a flexible material with a large amount of deformation, which produces a large pressure on the edge of the photovoltaic double-glass module. At the same time, the lamination temperature is high, and the glass is easily deformed when heated, resulting in blisters at the four corners of the photovoltaic double-glass module. , cannot be eliminated, seriously affecting the qualification rate of photovoltaic double-glass modules. [0003] Moreover, during the lamination process, the four corners are more stressed than other parts, which can easily lead to serious lack of glue at the four corn...
