Vacuum automatic film pasting system

Abstract

The invention relates to a vacuum automatic film pasting system, which comprises a film pasting mechanism and an air suction mechanism, wherein the film pasting mechanism comprises an upper cover plate and a lower cover plate, one edge of the upper cover plate is movably connected with one side of the lower movable plate, the upper cover plate is provided with an upper cover air cavity, a dismountable workpiece carrying plate is arranged on the lower cover plate and is provided with one or a plurality of workpiece placing grooves, the bottom surface of the upper cover plate is provided with upper cover film pasting absorption blocks in one-to-one correspondence to the workpiece placing grooves, the upper cover film pasting absorption blocks are provided with a plurality of air holes communicated with the upper cover air cavity, the air suction mechanism comprises a vacuum air storage tank and an air suction pipe, the air suction pipe is connected between the vacuum air storage tank and the upper cover air cavity, and an air suction control valve for controlling the air suction mechanism to suck the air is arranged on the air suction pipe. The lower cover plate is provided with a lower cover air cavity communicated with the air suction pipe, a lower cover film pasting absorption block is arranged on the lower cover plate, and the lower cover film pasting absorption block is provided with a plurality of air holes communicated with the lower cover air cavity. When the vacuum automatic film pasting system is adopted for pasting protection films on cases or screens, the film pasting accuracy and the film pasting smoothness can be effectively improved, the film pasting speed can be effectively accelerated, and the film pasting effect is improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone screen film sticking, in particular to a vacuum automatic film sticking system. Background technique [0002] The electronics industry mostly uses manual or labeling machines to stick films on screens and casings. The disadvantages of manual film sticking are low work efficiency, high labor costs, and prone to inaccurate sticking positions, uneven film sticking, or bubbles in the sticking film; Although the labeling machine can improve the working efficiency, each labeling machine can only apply film to a single type of product, and its application compatibility is poor. Limit the degree of automation of the film sticking process to a large extent. In addition, there is a problem of poor cleanliness of the operating environment for manual film application or labeling machine film application, which can easily lead to contamination of the lens or shell film, failing to meet product quali...

[0002] The electronics industry mostly uses manual or labeling machines to stick films on screens and casings. The disadvantages of manual film sticking are low work efficiency, high labor costs, and prone to inaccurate sticking positions, uneven sticking films, or bubbles in the sticking film; Although the labeling machine can improve the working efficiency, each labeling machine can only apply film to a single type of product, and its application compatibility is poor. Limit the degree of automation of the film sticking process to a large extent

In addition, there is a problem of poor cleanliness of the operating environment for manual film application or labeling machine film application, which may easily lead to contamination of the lens or shell film and fail to meet product quality requirements.
