Description

Technical Field

[0001] The utility model relates to the technical field of anti-peep films for touch screens, in particular to a production and film-sticking device for anti-peep films for touch screens. Background Art

[0002] Privacy film is a semi-rigid film made of plastic that covers the screen. It uses the world's unique ultra-fine blinds optical technology, which is a combination of the original anti-reflective film, anti-ultraviolet film, mirror film, and anti-radiation film with the new function of privacy film added. The information displayed on the screen is only for the user to read from the front, and anyone watching from the sides can only see a dark screen. It is mostly used in laptops and can effectively protect business secrets and personal privacy.

[0003] Existing touch screen privacy films are all applied manually, and the accuracy of manual application is low, resulting in unstable product quality and a high return rate. In addition, the speed of manual application is extremely slow, which reduces production efficiency.

[0004] For example, a glass panel film pasting device disclosed in Chinese patent CN211662783U has a simple structure and is easy to use. The protective film is adhered to the glass surface by rolling with a silicone wheel. After pasting, it is beautiful, firm, will not fall off by itself, and has no bubbles. The equipment is easy to operate and has high efficiency. Protective films of different materials can be used. By accurately aligning the product and the protective film, the efficiency of one-time film pasting is greatly improved.

[0005] However, when the film sticking device sticks the film on the panel, the touch screen is directly placed on the product fixing plate without clamping the touch screen, so that it is impossible to ensure that the touch screen does not shake during the film sticking.

[0006] For this reason, we urgently need to provide a production and film-sticking device for a touch screen privacy film that can clamp and fix the touch screen. Utility Model Content

[0007] The purpose of the utility model is to provide a production and laminating device for a touch screen anti-peep film, so as to solve the problem that when the laminating device laminating the film on the panel is proposed in the above background technology, the panel is directly placed on a product fixing plate without clamping the touch screen, thereby failing to ensure that the touch screen does not shake during laminating.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a production and film-sticking device for a touch screen anti-peep film, comprising a base plate, a rear fixing plate fixedly connected to the upper rear end of the base plate, a front fixing plate fixedly connected to the upper front end of the base plate, and a clamping mechanism connected between the rear fixing plate and the front fixing plate.

[0009] The clamping mechanism includes a limit rod, a bearing, a threaded rod, a handle and a movable plate. The limit rod is fixedly connected to the left and right ends of the side adjacent to the rear fixed plate and the front fixed plate, the bearing is fixedly connected to the left and right ends inside the rear fixed plate, the threaded rod is fixedly connected to the inner side of the bearing, the handle is fixedly connected to the front end of the threaded rod, and the movable plate is connected to the outer sides of the limit rod and the threaded rod.

[0010] A further improvement is that circular holes are opened at the left and right ends of the interior of the front fixing plate, and the outer side of the front end of the threaded rod is slidably connected to the inner side of the circular hole, so that the front fixing plate supports the front end of the threaded rod, so that when the handle is held and rotated, the threaded rod can be located in the bearing and the front fixing plate and rotate.

[0011] A further improvement is that sliding holes are opened at the left and right ends of the interior of the movable plate, and threaded holes are opened at the left and right ends of the interior of the movable plate. The outer side of the limit rod is slidably connected with the inner side of the sliding hole, so that the movable plate can only slide on the outer side of the limit rod, thereby limiting the movement of the movable plate. The outer side of the threaded rod is threadedly connected with the inner side of the threaded hole, so that when the handle is turned to rotate the threaded rod, the movable plate on the outer side of the threaded rod can be driven to move.

[0012] A further improvement is that the upper ends of the rear fixing plate and the front fixing plate are connected to a support frame, the upper end of the support frame is connected to a film sticking mechanism, the film sticking mechanism includes a sliding block, a round rod, a cylinder, a spring, a connecting rod, a ring, a fixed rod and an extrusion cylinder, the sliding block is connected to the upper end of the support frame, the round rod is connected to one side adjacent to two sliding blocks, the cylinder is fixedly connected to the lower side of the front and rear ends of the round rod, the spring is fixedly connected to the inner top end of the cylinder, the connecting rod is fixedly connected to the lower end of the spring, the ring is fixedly connected to the lower end of the connecting rod, the fixed rod is rotatably connected to the inner side of the ring, and the extrusion cylinder is fixedly connected to the outer side of the part of the fixing rod located between the rings.

[0013] A further improvement is that a sliding groove is provided at the inner upper end of the support frame, and grooves are provided around the outer side of the sliding block. The inner side of the sliding groove at the upper end of the support frame is slidably connected with the inner side of the groove at the outer end of the sliding block, so that the sliding block can slide inside the sliding groove at the upper end of the support frame.

[0014] A further improvement is that the outer side of the upper end of the connecting rod is slidably connected to the outer side of the lower end of the cylinder, thereby limiting the movement of the connecting rod.

[0015] A further improvement is that the front and rear sides of the extrusion cylinder are slidably connected to one side adjacent to the two circular rings, so that the position of the extrusion cylinder can be restricted between the two circular rings.

[0016] In summary, the present application discloses a production and laminating device for a touch screen privacy film.

[0017] The technical solution rotates the handle to rotate the threaded rod, thereby driving the movable plate outside the threaded rod to move along the limit rod, so that the touch screen to be film-coated placed on the bottom plate can be clamped between the rear fixed plate and the movable plate.

[0018] Further pushing the round rod makes the sliding block slide along the upper end of the support frame, which can drive the extrusion cylinder whose lower end is pushed by the spring to squeeze the protective film on the surface of the touch screen to slide along the surface of the protective film, thereby sticking the protective film to the surface of the film panel.
