[0004] The above-mentioned device uses a fixed groove to limit the tempered film, but the size of the tempered film is determined by the mobile phone. The sizes of mobile phones are diverse and change rapidly, which makes the sizes of tempered films large and needs to be updated frequently. The fixed groove in the above-mentioned device cannot limit tempered films of different sizes, and its practicality is low. The existing fully automatic laminating machine uses a deformable strip conveyor belt to block the tempered film on three sides to achieve positioning, but the three-side blocking is achieved by three independent electric push rods. After the size of the tempered film changes, it is not conducive to the laminating equipment to grasp the center point of the tempered film, and the three independent motors increase the equipment cost.

[0005] A film laminating device for toughened film packaging of mobile phones is proposed to solve the above-mentioned problems. Utility Model Content
