Description

Technical Field

[0001] The present invention belongs to the field of high-end 3C manufacturing, and particularly relates to a vacuum suction film laminating mechanism and a film laminating system. Background Art

[0002] With the development of technology, the manufacturing precision and requirements for 3C products (computer, communication, and consumer electronic products) are getting higher and higher. For a screen or a cover plate, the protective film covering its surface needs to be removed during the production and detection processes, and this process is collectively referred to as film tearing. After film tearing, a new cover plate or screen often needs to be covered with a protective film. One side of the protective film has adhesiveness. Conventionally, it is necessary for workers to peel or tear the protective film from the base film and then manually attach it to the cover plate through tools, and this process is collectively referred to as film laminating.

[0003] As described above, traditional film laminating is carried out manually, which not only easily causes secondary pollution to the cover plate or the screen, but also has low efficiency. Therefore, it is necessary to design an automatic and intelligent film laminating device. Summary of the Invention
