Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component tooling, in particular to an edge trimming knife for a photovoltaic double-glass component. Background Art

[0002] After the photovoltaic modules are laminated, the encapsulation EVA usually overflows, causing inconvenience to the subsequent framing process, so the overflowed EVA needs to be removed.

[0003] Since manual edge trimming tends to be uneven, resulting in an unsightly appearance of the module and is somewhat dangerous, most photovoltaic module production lines use machines for edge trimming.

[0004] At present, the trimming knife of the trimming machine can only trim the overflow glue around the side edges of the component, but cannot trim the glue film that overflows to the back glass. This part of the overflow glue will cause poor glue lines after framing, thereby affecting the sealing of the component. Utility Model Content
