Example Embodiment

[0026] Example one

[0027] See Figure 3~5 As shown, a laminating method for solar cell modules includes the following steps:

[0028] (1) Lay non-stick cloth on the heating table 3 of the laminator;

[0029] (2) Put the laminated semi-finished solar cell module 2 on the non-stick cloth of the heating table;

[0030] (3) Four mat strips 4 are arranged around the semi-finished solar cell module; the distance between each mat strip and the edge of the semi-finished solar cell module is 10-20 mm, and the thickness of the mat strip is larger than that of the semi-finished solar cell module. 1~2 mm smaller in thickness;

[0031] (4) Then lay the non-stick cloth 1 on the semi-finished solar cell module and the mat strip;

[0032] (5) Finally, vacuum, heat and pressurize the chamber of the laminator to obtain a solar cell module.

[0033] The semi-finished solar cell module refers to the module to be laminated after sorting, single welding, string welding, and lamination preparation.

Abstract

The invention discloses a method for laminating a solar battery module, which comprises the following steps of: (1) firstly, laying non-adhesive cloth on a heating table of a laminator; (2) secondly, placing the laminated semi-product of the solar battery module on the non-adhesive cloth on the heating table; (3) thirdly, providing four cushioning bars on the four sides of the semi-product of the solar battery module, wherein the distance from each cushioning bar to the edge of the semi-product of the solar battery module is 10 to 20mm; (4) fourthly, laying non-adhesive cloth on the semi-product of the solar battery module and the cushioning bars; and (5) fifthly, vacuuming, warming and pressurizing the materials into a whole in the cavity chamber of the laminator to obtain the solar battery module. In the laminating process, the concentrated stress points are transplanted to the cushioning bars, so that the phenomena of adhesive failure, bubbling, battery sheet displacement, module damage and the like are avoided; the yield is improved; and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a preparation method applied to solar cell components, in particular to a lamination method for solar cell components. Background technique [0002] At present, the continuous use of conventional energy has brought about a series of economic and social problems such as energy shortage and environmental degradation, and the development of solar cell modules is one of the ways to solve the above problems. Therefore, countries all over the world are actively developing solar cell modules. [0003] The existing technological process for preparing solar cell modules is: sorting, single welding, series welding, lamination preparation, lamination, and final assembly. Among them, what determines the final effect of the product is the lamination process. The existing lamination method is: first lay non-stick cloth on the heating table 3 of the laminator, then directly put the semi-finished solar cell module 2 on the non-stick cloth on...
