Abstract

The invention relates to a photovoltaic module lamination room, lamination equipment and lamination method. A photovoltaic module lamination chamber, comprising: an upper chamber casing; a lower chamber casing, which can be airtightly connected with the upper chamber casing, and has an air extraction hole at the bottom; a heating plate, arranged in the lower chamber casing, And do not cover the air extraction holes; laminate the lower cloth, made of airtight material, fixed on the lower chamber casing and cover the heating plate, for placing photovoltaic modules, and do not cover the air extraction holes; and lamination The upper cloth is made of an air-tight material, fixed in the casing of the upper chamber, and can cover the suction hole to generate pressure on the photovoltaic module when the lamination chamber is under negative pressure. By adjusting the structure of the equipment, the lamination chamber can avoid the use of silica gel plates.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a photovoltaic module lamination chamber, lamination equipment and a lamination method. Background technique [0002] The lamination process of photovoltaic modules is a key link in the production of modules. The laminator is composed of several parts such as pneumatic system, vacuum system, heating system, transportation system, and control system. The main laminated parts include the silicone plate, the upper chamber shell and the lower heating plate. [0003] At present, the heating temperature of the laminator is basically set at 140-150°C, the evacuation time is 5-8 minutes, the pressurization is 1-2 minutes, and the curing time is 9-15 minutes. The traditional lamination process is divided into vacuuming, heating components, and curing. three parts. The lamination process is to first pass the stacked components through the Teflon varnished cloth on the heating plate of the lowe...
