Positive pressure encapsulation device of building integrated photovoltaics (BIPV) solar energy component

Abstract

The invention discloses a positive pressure encapsulation device of a building integrated photovoltaics (BIPV) solar energy component. The positive pressure encapsulation device comprises a portal frame and a delivery mechanism penetrating through the portal frame, wherein an upper heating plate and a lower heating plate are arranged on the portal frame and connected with corresponding oil heaters, the lower heating plate is provided with a plurality of cambered surface type ejector pins, each cambered surface ejector pin is connected with an air cylinder, the upper surface of the upper heating plate is connected with an upper box, the upper surface of the upper box is connected with a plurality of hydraulic cylinders and connected with a hydraulic pressure station fixed on the top of the portal main frame, and the periphery of a matching end of the upper surface of the upper box and the lower heating plate is provided with an upper lining plate, a lower lining plate, a silica gel plate located between the upper lining plate and the lower lining plate, and an upper and a lower chambers which are formed by combining a silica gel strip inlaid on the upper surface of the upper lining plate with the silica gel plate. A double-glass battery component is simultaneously heated up and down, and is pressed positively, so that encapsulation requirements of a BIPV battery component with a large area and made of thick toughened glass are satisfied.

Description

technical field [0001] The invention relates to a solar module positive pressure packaging device, in particular to a BIPV photovoltaic integrated BIPV solar module positive pressure packaging device used in buildings. Background technique [0002] At present, photovoltaic curtain walls are increasingly becoming the development trend of today's building curtain walls. However, the double-glass cell modules used to make photovoltaic curtain walls need to withstand large static loads such as wind and snow, so they are required to be made of large-area and thicker tempered glass. The structure of the solar cell module packaging equipment currently used in the market generally includes the main frame welded by various rectangular tubes, the lower heating plate arranged on the main frame, the upper box arranged above the lower heating plate, the lower heating plate and the upper Rubber boards, lining boards, and sealing strips are arranged between the boxes to form upper and low...

AI Technical Summary

Problems solved by technology

The solar module packaging equipment with this structure has the following disadvantages for packaging BIPV components: 1. The components enter the heating plate and are heated without being evacuated, and the EVA will melt in advance to produce different degrees of air bubbles.

2. Only the lower chamber heats the components, the heating efficiency is low, and the heating degree of the upper and lower two pieces of glass is inconsistent, resulting in inconsistent stress release and affecting the strength of the components

3. The lamination pressure is atmospheric pressure, and there will be a phenomenon of inaccurate pressure for double-glass components
