Embodiment Construction

[0010] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0011] The lamination process of solar photovoltaic modules includes the following steps, a. Put the undamaged tempered glass flat on the workbench, put the glass wool side up, and spread it evenly on the glass with the EVA wool side up; wherein, EVA is placed In the center of the toughened glass plate, its edge is spaced from the edge of the glass. b. Arrange the checked battery strings on the EVA according to the requirements, with the positive pole of the battery sheet facing upward; c. Solder the positioned battery strings with reflow tape in turn, and use a vernier caliper to position the battery strings during the welding process; d. Place the filler correctly according to the calibrated position; e. Lay anot...

Abstract

The invention discloses a laminating process of a solar photovoltaic module. The laminating process includes the steps of a, placing lossless tempered glass flatly on a bench, with a textured face facing up, and evenly spreading EVA (ethylene-vinyl acetate copolymer) on the glass with the textured faces facing up; b, arranging cell strings checked out on the EVA as required, with anodes of the cells facing up; c, welding the positioned cell strings in order with a backflow tape, and positioning the cell strings with a vernier caliper during welding; d, according to a calibration position, placing filler correctly; 3, spreading a layer of EVA and TPT again, leading an anode of and a cathode of a cell module from pores, and fixing a header tape led out, to a back board through a transparent adhesive tape. The laminating process has the advantages that bubbles are avoided and the cell module is good in quality.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a stacking process of solar photovoltaic components. Background technique [0002] Module packaging is an important process link in the production process of solar cells. The quality of packaging determines the reliability of solar cell modules. The module line is also called the packaging line. Packaging is a key step in the production of solar cells. Without a good packaging process, no matter how good the battery is, no good module board can be produced. The packaging of the battery can not only ensure the life of the battery, but also enhance the resistance of the battery. The high quality and long life of the product are the key to win customer satisfaction, so the packaging quality of the component board is very important. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a stacking process...
