Working principle: The tape reel is installed in the unwinding mechanism. After the adhesive tape without bottom film is drawn out from the unwinding mechanism, it enters the die-cutting and laminating mechanism; the adhesive tape passes between the die-cutting roller and the bottom roller, and the die-cutting roller , When the bottom roller rotates, the die-cutting process of the adhesive tape is completed, and the film strip with the same shape as the surface of the supporting object is cut out; During the process, the positioning mold holding the sticker moves synchronously on the track to complete the filming process. The sticker strip is pasted on the sticker, and the remaining part of the adhesive tape passes between the laminating roller and the pressing roller. Stored in the rewinding mechanism.

The carrier is placed on the positioning mold by the injection molding machine picking manipulator, and fixed by the left and right clamps; after the positioning mold is moved to the filming position, the motor B works, the carrier is lifted, and the positioning mold is smoothed ( The path of the center curve of the lamination direction of the substrate moves forward, and the lamination roller rotates at a synchronous equal linear speed; the positioning mold moves to the unloading position (the end of the track), and the grabbing mechanism grabs the substrate , transported to the next equipment; positioning the mold back.

The film sticking device is divided into two stations, left and right. The left and right stations independently complete the filming process of the left and right mirrored substrates. The two stations share a control system to complete the filming process synchronously.

Compared with the prior art, the beneficial effects that the utility model has are:

1. The utility model realizes the curved surface filming without the bottom film adhesive tape, which replaces the manual filming and improves the work efficiency;

2. The utility model realizes the use of the adhesive tape without a bottom film, replaces the adhesive tape with a bottom film, and reduces the cost;

3. The adhesive tape without bottom film is directly laminated after die-cutting, and the interval between die-cutting and lamination is short, which ensures the quality of the film;

4. The utility model has two workstations, which can be processed synchronously, and is especially suitable for paired mirrored substrates.
