Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a film belt cutting device, belonging to the field of film pasting machines. Background Art

[0002] A film pasting machine is a highly precise and intelligent device. It adopts an advanced mechanical structure and a precise control system, and can realize fast and accurate film pasting actions. Through technical means such as vacuum adsorption and roller lamination, it ensures that the film is closely attached to the product surface during the film pasting process, without bubbles and wrinkles. Whether it is a flat product or a curved product, the film pasting machine can handle it with ease.

[0003] A film belt is pasted at the solder belt between battery cells. The film belt has a transparent adhesive layer and an aluminized layer. The purpose of pasting the film belt is to facilitate the reflection of light and improve the power of the battery panel. However, since the adjacent solder belts are not flush and there are protrusions, if the protrusions of two battery panels are in contact, a short circuit will occur when the aluminized layers on the film belt are connected, which will damage the performance of the battery panel, reduce the power generation efficiency, and even may cause potential safety hazards, thus affecting the normal use of the battery panel.

[0004] Therefore, it is urgent to improve the film belt cutting device to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a film belt cutting device, which can cut off the metal layer of the metal film through the film belt cutting device while keeping the transparent adhesive layer intact, so as to ensure that the film belt does not shrink and deform during lamination. After removing the metal layer, the possibility of short circuit between battery strings can be eliminated, thereby improving the production quality of the battery panel and extending its service life.
