The invention discloses a method for selectively removing a transparent coating on the surface of a workpiece through laser scanning, which comprises the following steps of: firstly, covering the transparent coating on the surface of the workpiece with a transparent flexible film, filling photosensitive glue between the transparent flexible film and the workpiece, and then curing the photosensitive glue on a custom pattern part by using ultraviolet laser to penetrate through the transparent flexible film to obtain the transparent coating on the surface of the workpiece. Then infrared laser is used for heating the cured photosensitive adhesive layer, so that heat is conducted to the transparent coating, the transparent coating is softened, the photosensitive adhesive layer and the transparent coating are further glued, finally, the transparent flexible film is stripped, and the transparent coating of the user-defined pattern part is removed. According to the method, the transparent coating on the surface of the workpiece is rapidly, accurately and selectively removed, the surface of the workpiece is not damaged, and the method is convenient, rapid, high in safety, environmentally friendly and free of pollution.

This invention discloses an adjustable matte film partial lamination packaging processing device, belonging to the field of packaging processing technology. The device includes a fixed support frame mounted above a packaging conveyor. Two adjustable adjustable frames are movably mounted on the left and right sides of the top of the fixed support frame. Inside the adjustable frames are liftable suction frames and material support frames, enabling adaptive picking and positioning of packaging pieces of different widths. A cleaning component, a lamination component, and a cutting component are also movably mounted on the fixed support frame, which can sequentially perform cleaning, hot-press lamination, and laser cutting on the surface of the packaging pieces. This invention, through its adjustable positioning structure and multi-process structure, achieves high-precision partial lamination and cutting of matte film on packaging pieces, effectively improving processing quality and production efficiency, and is suitable for automated processing of packaging pieces of various specifications.
