Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module production equipment technology, specifically to a photovoltaic module edge trimming device. Background Technology
[0002] Laminated solar cells are a crucial step in photovoltaic (PV) module manufacturing. The lamination process tightly bonds solar cells with other materials to form a complete solar panel. During lamination, due to factors such as poor precision in the encapsulating film application and misalignment within the laminator cavity, residual encapsulant can form on the sides and edges of the backsheet of the PV laminate. Therefore, edge trimming is necessary after lamination to improve the module's appearance and performance, laying a solid foundation for subsequent adhesive application, frame assembly, and testing.
[0003] Metal beveling tools with rounded blades are commonly used to bevele laminates. However, these rounded blades are prone to wear after prolonged use, leading to blade deformation or abnormal leveling. When the rounded blades become deformed or abnormal, it can easily cause batch explosions of laminates. Utility Model Content

The trimming module 3 is detachably mounted on the upper surface of the movable block 41, and the trimming module 3 is moved along the sliding track 2 by driving the roller to roll through the second drive motor 42.
[0042] In a preferred embodiment, the sliding track 2 has two spaced-apart first limiting protrusions 21 and a roller channel 22 disposed between the two first limiting protrusions 21. The moving block 41 is provided with two first sliding slots 410, in which the first limiting protrusions 21 are slidably disposed one-to-one, and the roller is disposed between the two first limiting protrusions 21 and driven by the second drive motor 42 to roll along the roller channel 22.

The moving block 41 has two second limiting protrusions that are slidably configured one-to-one in the second sliding slots, and the roller is disposed between the two second limiting protrusions and driven by the second drive motor 42 to roll along the roller channel 22.
