Problems solved by technology

[0002] At present, when silicon solar cell modules are laminated, the process of placing the laminated parts directly on the PTFE cloth of the laminator is used for lamination. After lamination by this process, the excess EVA material is laminated. It will remain on the PTFE cloth of the equipment when the PTFE cloth is recycled, and the residual EVA on the PTFE cloth will be transferred to the glass of the laminate during the lamination process of the laminate, but EVA is a glue , sticking to the glass is very difficult to remove, resulting in increased cleaning workload, low production efficiency, and unqualified cleaning

Embodiment

[0019] A lamination method for easy cleaning of photovoltaic modules, the method includes the following process steps:

[0020] (1) First, spread high-temperature PTFE cloth on the feeding and conveying table of the laminator;

[0021] (2) Lay the cellophane discarded in other processes in order according to the position where the laminate is placed.

[0022] (3) Place the laminate to be processed in the position where the cellophane is pre-laid, and place them in order to completely isolate the laminate from the high-temperature PTFE cloth;

[0023] (4) Laminating the laminate.

[0024] This method does not leave the excess EVA glue on the PTFE cloth, and can prevent the EVA glue from the tetrafluoro cloth from being transferred to the glass surface, effectively ensuring the glass surface is clean, thereby reducing the workload of the cleaning process and saving Production time improves production efficiency, and cellophane can use waste materials from other processes without addition...

Abstract

The invention relates to a laminating method convenient for cleaning a photovoltaic assembly. The method comprises the following steps of: (1) laying high-temperature polytetrafluoroethylene (PTFE) cloth on a feeding transmission table of a laminating machine; (2) laying glass paper on the high-temperature PTFE cloth; (3) placing a to-be-machined laminating component on the glass paper; and (4) laminating the laminating component. Compared with the prior art, the laminating method provided by the invention is low in cost and high in production efficiency.

Description

Technical field [0001] The invention relates to the field of photovoltaic module production, in particular to a lamination method that facilitates the cleaning of photovoltaic modules. Background technique [0002] At present, when silicon solar cell modules are laminated, the laminate is directly placed on the PTFE cloth of the laminator to feed and laminate. After using this process, the excess EVA material is laminated When the PTFE cloth is recycled, the residual EVA on the PTFE cloth will be transferred to the glass of the laminate during the lamination process of the laminate, but EVA is a glue , It is very difficult to remove it sticking to the glass, resulting in increased cleaning workload, low production efficiency, and unqualified cleaning. Summary of the invention [0003] The purpose of the present invention is to provide a laminating method with low cost and high production efficiency in order to overcome the above-mentioned defects in the prior art. [0004] The pur...
