Description

Double-glass assembly lamination anti-overvoltage frame

Technical Field

The utility model relates to a dual glass assembly lamination device, especially an anti-over-pressure frame.

Background

At present, in the photovoltaic industry, a single crystal PERC double-sided battery piece becomes the mainstream of the market, and a double-sided double-glass assembly can generate electricity on the front side and the back side, has the advantages of long life cycle, low attenuation rate, high weather resistance and fire resistance, good heat dissipation, good insulation and the like, and gradually becomes a necessary packaging process of a high-efficiency assembly.

Compared with the production process of the single-glass assembly, the key process of the production of the double-glass assembly is lamination. Because of the double glass assembly back replaces conventional backplate with glass, the pressure that flexible silica gel board applied at the glass edge is great in the lamination process, squeezes the glued membrane at edge to the subassembly in the middle of, drives the battery cluster and produces the aversion to make the phenomenon that thickness is less than the subassembly middle part appear because of "excessive pressure" in subassembly border position. After lamination is finished and pressure applied by the silica gel plate is removed, the edge of the glass has rebound bubbles and adhesive film loss under the action of tension. In the long-time outdoor operation process of the dual-glass assembly, the edge is subjected to overvoltage, the edge of the assembly is delaminated due to the continuous tension of glass, and the product yield and the service life are seriously affected.

In order to solve the problems, the main solution at present is as follows: before lamination, the assembly is fitted with an anti-overstress frame, so that the force exerted by the silicone sheet on the edge of the assembly is transferred to the anti-overstress frame. The method has good effect on reducing string displacement and bubbles caused by overpressure at the edge position of the component, but the pressure at the corner position of the component is still larger, hidden cracks and bubbles caused by overpressure still often appear, and on the other hand, the phenomenon of frame jumping is easy to appear when bumping and regulating actions are carried out through a production line due to lack of constraint between the frame and the component in the process of flowing the component along with the overpressure-preventing frame, so that the frame is pressed on glass, and the glass is crushed in the laminating process to cause component scrapping.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: to the above problem, the utility model aims at providing an excessive pressure frame is prevented in dual glass assembly lamination makes it not take place "jump the frame" phenomenon following the subassembly circulation in-process to can alleviate the local excessive pressure phenomenon in subassembly corner position.

The technical scheme is as follows: the utility model provides a frame that excessive pressure is prevented in dual glass assembly lamination, includes rectangular frame, corner cushion, high temperature cloth A, high temperature cloth B, the corner cushion is in install respectively on four right angles of rectangular frame upper surface the rectangular frame upper surface, high temperature cloth A draws the setting to one side in four right angle regions, connects every adjacent long limit of group and minor face the width direction of rectangular frame upper surface, high temperature cloth B draws the setting to one side in two right angle regions, connects every adjacent long limit of group and minor face, high temperature cloth A set up the position compare in high temperature cloth B to the rectangular frame center is gathered together, and dual glass assembly places in the rectangular frame and be in high temperature cloth A with between the high temperature cloth B.

Further, the double-glass assembly is placed in the rectangular frame, and a gap is formed between the inner side of each long side and each short side, and the gap provides a space for glue overflow generated in lamination.

Preferably, the width of the gap is 5-10 mm.

Furthermore, the thickness of the corner cushion block is 3-4 mm. Four right-angle corner parts of the rectangular frame are heightened through the corner cushion blocks, and the pressure of the corner parts is further reduced.

Further, the thickness of rectangular frame is dual glass assembly thickness +0 ~ 2 mm.

Further, the long edge of the high-temperature cloth B is arranged at the front end of the advancing direction of the double-glass assembly.

Furthermore, when the high-temperature cloth A and the high-temperature cloth B are respectively connected with each group of adjacent long sides and short sides, an isosceles triangle is formed.

Has the advantages that: compared with the prior art, the utility model has the advantages that: this prevent excessive pressure frame structure fixes dual glass assembly, and dual glass assembly receives the high temperature cloth A that is located the top and the high temperature cloth B dual restraint that is located the below in the direction of feed, consequently can not appear "jumping the frame" phenomenon, stops dual glass assembly circulation in-process because of "jumping the frame" the laminated glass who leads to broken, and the effect of cooperation corner cushion can reduce the hidden production probability that splits in dual glass assembly four corners position, improves dual glass assembly's qualification rate.
