Embodiments of the invention

In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

Figures 1 and 2 show the structure of the film cutting positioning plate provided in Embodiment 1 of the present invention. For convenience of explanation, only the parts related to the embodiment of the present invention are shown.

A film cutting positioning plate, the film cutting positioning plate includes a film cutting positioning plate body, the film cutting positioning plate body includes:

Position layer 1; and

Cover the release film positioning layer 2 attached to the positioning plate layer 1;

The positioning plate layer 1 includes a positioning plate hard layer 11 and a film fixing layer 12 covering the upper surface of the positioning plate hard layer 11. The release film positioning layer 2 is adhered through the adhesion or adsorption of the film fixing layer 12. Closed on the upper surface of the hard layer 11 of the positioning plate;

The release film positioning layer 2 includes a positioning edge 21 that functions as an edge positioning. The area formed by the film fixing layer 12 not covered by the positioning edge 21 is a positioning and fitting area for fitting and fixing the cutting film.

This film cutting positioning plate is not only suitable for cutting mobile phone films, but also suitable for other products that require screen protection, such as tablet computers, etc.

As an embodiment of the present invention, the release film positioning layer 2 also includes a release film 22 that can be peeled off and removed. Before the cutting operation, the release film 22 covers the positioning sticker formed on the film fixing layer 12 Combined area for dust protection.

As an embodiment of the present invention, the positioning edge 21 has various shapes, including single-sided positioning, 2-sided positioning, 3-sided positioning or 4-sided positioning. This can be adapted to fit and secure mobile phone films of various sizes.

Figure 3 shows the structure of the film cutting positioning plate provided in Embodiment 2 of the present invention, in which the shape of the positioning edge 21 is four-sided positioning, and one of the corners is designed as a bevel to facilitate the removal of the cutting film after the cutting is completed.

As an embodiment of the present invention, the thickness of the positioning plate hard layer 11 is between 10 μm and 5000 μm. The hard layer 11 of the positioning plate is selected to have a suitable thickness, so that it can smoothly enter and exit all current smartphone film cutting machines after being attached to the cutting film. The material of the hard layer 11 of the positioning plate is all hard materials, including but not limited to cardboard, PC, PET, ABS, etc., and the production process can be die cutting, injection molding, CNC, laser cutting, 3D printing, etc.

The hard layer 11 of the positioning plate is selected to have an appropriate thickness, which can be adapted to all types of current smart film cutting machines, ensuring smooth paper feeding without lag, and solving the problem of slippage and uneven cuts in some old film cutting machines.

As an embodiment of the present invention, the film fixing layer 12 is made of an adhesive or adsorbable material, with appropriate viscosity selected, so that the cutting film can be firmly adhered without loosening, and can be easily removed after cutting and used repeatedly. Materials that can be pasted or adsorbed include but are not limited to silicone, acrylic glue, printing water glue, oil glue, electrostatic adsorption film, etc., with a thickness of 1μm-2000μm.
