Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, a manufacturing method of a double-glass module, which includes double-glass module laying, visual inspection, EL test, hot-melt lamination, installation of junction box, secondary EL test, power test and finished product inspection;

[0024] The laying steps of the double-glass module specifically include: first laying the cut EVA adhesive film on the bottom tempered glass; then laying the required number of solar cell strings on the EVA adhesive film; secondly, connecting the solar cell strings The strips are connected in series as a whole; EVA adhesive film and surface layer tempered glass are laid sequentially on the solar cell string again to form a solar double-glass module; finally, a high-temperature adhesive tape 1 is used for edge sealing and drilling; the width of the high-temperature adhesive tape 1 of the p...

Abstract

The invention discloses a double-glass assembly manufacturing method, and the method comprises the steps: double-glass assembly laying, appearance inspection, EL testing, hot melting laminating, junction box installation, secondary EL testing, power testing, and finished product examination. The double-glass assembly laying specifically comprises the steps: firstly enabling a cut EVA glue film to be laid on bottom toughened glass; secondly enabling a required number of solar cells to be laid on the EVA glue film; thirdly enabling the plurality of cells to be connected in series through a bus bar to form a body; fourthly sequentially laying the EVA glue film and surface roughened glass on the solar cell string, and forming a solar double-glass assembly; and finally carrying out edge sealing through a high-temperature adhesive tape, and drilling. According to the invention, the high-temperature adhesive tape is used for fully pasting and sealing the periphery of the laid double-glass assembly, thereby effectively controlling the overflow quantity. The method greatly shortens the laminating time, and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of preparation of photovoltaic double-glass components, in particular to a double-glass component using EVA as a packaging material, in particular to a method for manufacturing a double-glass component. Background technique [0002] At present, there are many types of photovoltaic double-glass modules, and the laying processes used are also different. At present, most of the double-glass modules are packaged with materials with relatively poor fluidity such as PVB and POE. The prices of PVB and POE are between Now the price in the market is relatively high, about 1.5 to 2 times the price of ordinary EVA, which is quite expensive; but the use of ordinary EVA has better fluidity, and after lamination, the components will appear uneven and the edges will be thinner , the middle area is thicker, the edge glass is more curved, and there is a certain stress between the glass and EVA, which is prone to delamination during in...
