Description

Technical Field

[0002] High-precision laminating equipment is an industrial automation product controlled by PLC or single-chip microcomputer, and is one of the equipment used for laminating mobile phone screens. The laminating principle is to place the mobile phone LCD screen and glass cover in a vacuum box in a vacuum environment, use the cylinder pressure of the machine to lower the inner mold of the vacuum cylinder, and completely press the glass cover placed on the lower mold of the vacuum cylinder and the LCD screen, thereby completing the key process in mobile phone screen repair.

[0003] In view of this, Chinese patent number CN213303005U proposes a precision OCA laminating device. Through the buffer structure, a buffer can be formed in the process of laminating the laminating block to the placement seat, avoiding the sudden impact of the laminating block, and ensuring the integrity of the relevant structure. The buffer structure uses a spring for buffering, and can be reset after use. At the same time, the guide frame can be disassembled, which is convenient for disassembly and replacement, and is flexible to use. In the above patents, when the high-precision laminating equipment performs elastic buffering, the buffer end has no stabilizing mechanism, which makes it easy to cause the hidden danger of vacuum instability due to the unstable elasticity of the bottom when performing vacuum extrusion;
