DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0018] Example 1: Please refer to Figure 1 , a protective film for an automatic film laminating machine, comprising a mobile phone film body 1, characterized in that: a first separation line 2-1 and a second separation line 4-1 are respectively arranged at both ends of the mobile phone film body 1, and the ends of both ends of the mobile phone film body 1 are respectively divided into a first positioning function area 2 and a second positioning function area 4 by the first separation line 2-1 and the second separation line 4-1, and the middle part of the mobile phone film body 1 is divided into an operation function area 3 by the first separation line 2-1 and the second separation line 4-1, and the first positioning function area 2 and the second positioning function area 4 are used for engraving positioning holes by a cutting machine, and an operation function area half-broken line 3-1 is arranged on one side of the mobile phone film body 1, so that the operation function area 3 forms a functional pull ring, and the operation function area half-broken line 3-1 is used to exclude non-use areas around the screen film.

[0019] See also Figure 1 , Figure 2 The mobile phone film body 1 is a four-layer structure, which includes a positioning film 101 located at the first layer, a protective film 102 located at the second layer, an application protective film 103 located at the third layer, and a release protective film 104 located at the fourth layer. The four layers are adhesively connected.

[0020] See also Figure 1 , Figure 3The four ends of the positioning film 101 are respectively provided with a first intermittent exhaust line 101-1, a second intermittent exhaust line 101-2, a third intermittent exhaust line 101-3, and a fourth intermittent exhaust line 101-4. Each intermittent exhaust line is used to allow the protective film 102 to form a natural curvature when bonding a curved screen mobile phone to avoid bubbles during the bonding process. At the same time, the semi-broken structure can play a supporting role before the protective film 102 is bonded to the screen to achieve a one-time bonding, thereby avoiding the protective film 102 from contacting the screen part before formal bonding and generating bubbles and dust spots. The first separation line 2-1 and the second separation line 4-1 can be used to divide the cutting area to reduce the difficulty of separating each layer. In addition, by moving the position of the separation line outside the functional area, the problem of creases in the middle of traditional materials due to bending during the film bonding process can be avoided.

[0021] Embodiment 2: Based on embodiment 1, the positioning film 101 is made of transparent polyester resin PET with a thickness of 100um and coated with 15um Silicone (glass peeling force 3g), and the protective film 102 is made of transparent polyester resin PET with a thickness of 75um and coated with 12um Acrylics OCA glue (glass peeling force 2g).

[0022] Furthermore, the application protective film 103 is made of Japan Toray optical-grade transparent TPE with a thickness of 125um and coated with Acrylics acrylic OCA glue 35um and self-repairing coating 30um (glass peeling force 600-800g), which can effectively prevent scratches and recover in a short time, keeping the protective film durable and new. The release protective film 104 is made of transparent polyester resin PET with a thickness of 38um and coated with ultra-light Acrylics acrylic OCA release agent (peeling force 1-2g), ensuring easy separation without generating bubbles.

[0023] Working principle: The mobile phone film body 1 is separated from each positioning functional area by various fault lines and attached to the mobile phone screen film. The first positioning functional area 2 and the second positioning functional area 4 are used to position the mobile phone film body 1 and the mobile phone screen film for accurate matching. The positioning functional area cooperates with the film laminating machine positioning component to make the mobile phone film body 1 accurately correspond to the mobile phone. The positioning component is pushed downward and translated by the machine's pneumatic principle to make the mobile phone film body 1 attached to the mobile phone screen film, which can ensure the accuracy of the film laminating position and avoid the generation of bubbles, freeing your hands to automatically complete the film laminating.
