Description

Technical Field

[0001] The utility model relates to the technical field of film sticking devices, in particular to a double-sided film sticking device with automatic turning over. Background Art

[0002] Some parts need to be pasted with films on both sides. The existing film pasting operation method is inefficient. In the existing multi-station film pasting, the film on the first side is pasted at the first station, and then the film on the second side is pasted at the second station.

The film pasting mechanism includes a product carrier and a first film pasting component arranged on the side of the product carrier, the product carrier is rotatably mounted on the frame and is used for placing the film-to-be-filmed part, and the first film pasting component is used to adhere the film material layer of the film roll material to the surface of the film-to-be-filmed part. The material collection mechanism is used to recycle the film roll material after the film pasting process is completed. The technical solution of the present invention can solve the problems of low efficiency, poor consistency and high cost of manual film pasting.
