Technical Field

[0001] This utility model belongs to the technical field of film application devices, specifically a high-efficiency film application device. Background Technology

[0002] As the name suggests, a film applicator is a device that applies protective film to corresponding items. According to the degree of automation, it can be divided into: manual film applicator, semi-automatic film applicator, and fully automatic film applicator. According to the application scenario, it can be divided into: flat film applicator, round bottle film applicator, side labeling machine, etc., and is widely used in the fields of electronic product manufacturing, automobile manufacturing, construction industry, advertising production, etc.

It includes a frame, a first support platform for carrying the film, a second support platform for carrying the display screen, a film suction assembly, and a film pressing assembly. The frame is provided with a film placement position, a film suction position, a film application position, and a film pressing position. The first support platform is connected to a first moving member, which moves the first support platform to the film placement position and the film suction position. The film suction assembly is connected to a second moving member, which moves the film suction assembly above the film suction position and above the film application position. The second support platform is connected to a third moving member, which moves the second support platform to the film application position and the film pressing position. The film pressing assembly is located above the film pressing position, which can minimize the generation of air bubbles during film application on the display screen, thereby improving the film application effect.

[0043] Working principle and process: The film is placed in the placement frame 7, and the item to be filmed is placed in the placement slot 6 with the side to be filmed facing upwards. The first motor 204 of the rotating assembly 2 is started, which in turn drives the driven gear 202 to rotate. This causes the rotating column 201 to rotate the rotating bracket 3 until the rotating bracket 3 is above the placement frame 7. The first electric telescopic rod 401 of the film suction assembly 4 is started, which extends the horizontal plate 402, causing the vertical tube 403 and vacuum suction cup 404 to move downwards until the vacuum suction cup 404 contacts the film. The vacuum generator 407 is started, causing the film to adhere to the vacuum suction cup 404. The first electric telescopic rod 401 is started, causing the film to move upwards. The rotating assembly 2 is started, transferring the film to the top of the placement slot 6. The first electric telescopic rod 401 is started, causing the film to move downwards to near the placement slot 6. Position the item, activate the second electric telescopic rod 501, which extends, causing the mounting bracket 502 to move downwards until the pressure roller 505 presses the center of the film onto the item. Activate the second motor 5034 of the displacement assembly 503, causing the lead screw 5031 to rotate. Under the action of the threaded hole 5035 and the positioning rod 5032, the moving block 5033 drives the U-shaped frame 504 and the pressure roller 505 to move to the left. Simultaneously, the first electric telescopic rod 401 on the left side extends, allowing the pressure roller 505 to gradually attach the film to the left half. Then, the second motor 5034 reverses, causing the pressure roller 505 to roll to the right. At the same time, the first electric telescopic rod 401 on the right side extends, allowing the pressure roller 505 to gradually attach the film to the right half. Turn off the vacuum generator 407 to release the film, thus completing the film application process.
