Technical Field

[0001] This utility model relates to the technical field of hot pressing devices, specifically a hot pressing dustproof sealing device for mobile phone lens protective films. Background Technology

[0002] A mobile phone lens protector is a special film designed to protect the rear camera of a mobile phone. It can effectively prevent the lens from being scratched, bumped, or contaminated with dust during daily use, thus extending the lens's lifespan.

[0003] Currently, when installing protective films on mobile phone lenses, hot pressing is usually required to tightly bond the lens protective film to the mobile phone lens or lens mount. However, existing hot pressing devices do not have an effective dustproof structure. During operation, the airflow can easily carry dust onto the mobile phone lens, and when dust settles on the lens, it cannot be cleaned in time, affecting product quality. Therefore, a hot pressing dustproof sealing device for mobile phone lens protective films is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hot-press dustproof sealing device for mobile phone lens protection sheets, which solves the problems mentioned in the background.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 A hot-press dustproof sealing device for mobile phone lens protection film includes a base 1, a substrate 2 is provided on the upper surface of the base 1, a dustproof box 3 is provided on the upper surface of the base 1 and outside the substrate 2, a cylinder 5 is provided on the upper surface of the dustproof box 3, a piston rod 501 is provided inside the cylinder 5, the lower end of the piston rod 501 passes through the upper wall of the dustproof box 3 and is provided with a hot-press plate 6, and a dust removal component 7 is provided on one side of the hot-press plate 6.

[0025] The dust removal assembly 7 includes an air cylinder 701, a push-pull rod 702, and a piston head 703. The air cylinder 701 is located on one side of the hot press plate 6. The upper end of the air cylinder 701 is connected to the upper wall of the dustproof box 3. A round hole corresponding to the opening at the upper end of the air cylinder 701 is opened on the upper wall of the dustproof box 3. The push-pull rod 702 and the piston head 703 are both located inside the air cylinder 701.

[0026] The dustproof box 3 has threaded holes 302 on both sides of its side walls, and filter screens 4 are threadedly connected to both sides of its side walls through the threaded holes 302. The dustproof box 3 has an opening on its front side, and a movable door 301 is provided at the opening on its front side. The threaded holes 302 on both sides of the dustproof box 3 facilitate the installation of filter screens 4. When external airflow enters the dustproof box 3, the filter screens 4 can effectively filter the dust in the airflow.

[0027] The dust removal assembly 7 also includes a lifting rod 704, an air blowing pipe 705, and a top connecting rod 706. The lower end of the lifting rod 704 is connected to the hot press plate 6, and the upper end of the lifting rod 704 passes through the upper wall of the dustproof box 3 and is connected to the top connecting rod 706. The push-pull rod 702 is set on the upper surface of the piston head 703. The upper end of the push-pull rod 702 passes through the round hole on the upper wall of the dustproof box 3 and is connected to the top connecting rod 706. When the cylinder 5 works, the piston rod 501 pushes the hot press plate 6 down. When the hot press plate 6 moves down, it will drive the lifting rod 704 down synchronously. Then, under the action of the top connecting rod 706, it will drive the push-pull rod 702 down synchronously. During the downward movement of the push-pull rod 702, the gas inside the air cylinder 701 can be pushed out through the piston head 703 and blown towards the mobile phone lens through the air blowing pipe 705. The exhaust gas generates an impact force to blow away the dust.

[0028] The hot press plate 6 has an avoidance groove 602 on the side near the air cylinder 701, and a positioning groove 201 is provided on the upper surface of the substrate 2. A gas pipe 601 is provided on the upper surface of the hot press plate 6 and on the side of the piston rod 501. The positioning groove 201 on the substrate 2 facilitates the placement of the mobile phone lens and limits its position. When an external vacuum pump is used, air is drawn in through the gas pipe 601 to form a negative pressure on the surface of the hot press plate 6. The protective sheet is tightly attached to the hot press plate 6 through the adsorption hole. When the hot press plate 6 moves down, the avoidance groove 602 can effectively prevent it from contacting the air blowing pipe 705.

[0029] Guide posts are provided on both sides of the upper surface of the substrate 2. The upper end of the guide post passes through the hot press plate 6 and is connected to the upper wall of the dustproof box 3. The hot press plate 6 is slidably connected to the guide post. By providing the guide post, the hot press plate 6 can effectively guide the movement of the hot press plate 6 up and down, and prevent the hot press plate 6 from shifting position.

[0030] The working principle is as follows: a positioning groove 201 is provided on the substrate 2 to facilitate the placement of the mobile phone lens and to limit the position of the mobile phone lens. An external vacuum pump is used to draw air through the gas pipe 601 to form a negative pressure on the surface of the hot press plate 6. The protective sheet is tightly attached to the hot press plate 6 through the adsorption hole. When the cylinder 5 is working, the piston rod 501 pushes the hot press plate 6 to move down. When the hot press plate 6 moves down, it will drive the lifting rod 704 to move down synchronously. Then, under the action of the top connecting rod 706, it will drive the push-pull rod 702 to move down synchronously. During the downward movement of the push-pull rod 702, the gas inside the air cylinder 701 can be pushed out through the piston head 703 and blown towards the mobile phone lens through the air blowing pipe 705. The impact force generated by the discharged gas blows away the dust.

[0031] Furthermore, when the hot press plate 6 moves down, it can effectively avoid contact with the air blowing pipe 705 through the provided avoidance slot 602. By providing threaded holes 302 on both sides of the dustproof box 3, it is convenient to install the filter screen plate 4. When the external airflow enters the dustproof box 3, the filter screen plate 4 can effectively filter the dust in the airflow.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
