Laminating tool for preventing flexible photovoltaic module from wrinkling

Abstract

The invention discloses a lamination tool for preventing a flexible photovoltaic module from wrinkling, and relates to the technical field of photovoltaic modules. The tool comprises four L-shaped tool modules and a limiting piece which is at least arranged on one L-shaped tool module. One end of each L-shaped tool module is a first end, the other end of each L-shaped tool module is a second end, the first end of each L-shaped tool module can be assembled with the second end of another L-shaped tool module, and the four L-shaped tool modules enclose a rectangular space for placing a flexible photovoltaic module after being assembled; and the limiting piece partially extends into the rectangular space and is used for downwards pressing the flexible photovoltaic module in the rectangular space. By adopting the technical scheme, the defects that the surface or the back surface of the existing flexible photovoltaic module is easy to wrinkle and the overall thickness is inconsistent in the production process are overcome.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a lamination tooling for preventing the wrinkles of flexible photovoltaic modules. Background technique [0002] At present, solar energy as a clean energy is widely and maturely applied to all aspects of people's lives; with the development of the photovoltaic industry, flexible photovoltaic modules are widely used in RVs, yachts, and factory roofs due to their advantages of light weight, bendability, and high efficiency. , wall area. [0003] During the lamination process of flexible photovoltaic modules, due to the inconsistent temperature resistance and thermal shrinkage coefficient of different packaging materials, the surface or back sheet of the module will be wrinkled during the lamination process. The phenomenon of uneven surface and different thicknesses will occur; surface wrinkles, backplane wrinkles, and thickness inconsistencies of flexible photovoltai...

AI Technical Summary

Problems solved by technology

[0003] During the lamination process of flexible photovoltaic modules, due to the inconsistency of the temperature resistance and heat shrinkage coefficient of different packaging materials, the surface or backplane of the modules will be deformed during the lamination process. Wrinkles, and at the same time, due to the wrinkles after the material shrinks, the surface of the flexible module will be uneven and the thickness will be different; the surface wrinkles, backplane wrinkles, and thickness of the flexible photovoltaic module are all unfavorable phenomena caused by production; greatly increase Product production cost

[0004]Aiming at the occurrence of the above phenomena, the general solution in the industry is to adjust the lamination parameters of the laminator to prolong the lamination time of the flexible components; use low temperature feeding, Heat up during the lamination process, after lamination, lower the temperature of the laminator, and then discharge the material. Although this method can solve the phenomenon of flexible component wrinkles, the lamination time is long, the production cost is high, and the efficiency is low; Materials with similar temperature resistance are used to encapsulate flexible photovoltaic modules, or according to the calculation of the shrinkage coefficient of the surface material or back material, the material is cut and blanked according to the proportion, and the surrounding edges of the material are fixed with double-sided sealant when stacking. This method There are certain restrictions on the packaging materials of flexible photovoltaic modules, and the cost of packaging materials is high, and the production process is cumbersome
