By means of the step-by-step pressure applying mode, gas can be exhausted more effectively, and steam pockets are reduced to the maximum extent; the connecting rods are arranged on the two sides of the bearing seat, and when the base material is subjected to film pasting, the two sides of one end of the film are fixed through the clamping plates, so that a certain angle is always kept between the non-pasted part of the film and the base material in the pasting process, and it is guaranteed that the film is separated from the base material before being pressed. In this way, the situation that the film and the base material are completely attached too early, and gas is sealed inside can be avoided, so that the possibility of steam pocket generation is further reduced, the attached film is smoother and tighter, and the film attaching quality is improved.

Description

Technical Field

[0001] This utility model relates to the field of film application equipment technology, specifically a film application machine. Background Technology

[0002] Currently, the application of film to substrates similar to those shown in the image largely relies on manual operation. For example, the film must be manually placed at a certain angle along the edge of the substrate, then a moving platform is pushed to press the film onto the substrate surface via rollers, followed by manual trimming of excess film. This manual method is not only inefficient but also requires highly skilled operators, making it difficult to guarantee consistent film application quality. Furthermore, air pockets are prone to form during the application process, affecting the final result. Therefore, a film application machine that can automate the application process and improve film application quality is needed. Utility Model Content

[0003] The purpose of this invention is to provide a film applicator to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a film applicator, comprising a mounting base, a connecting base, and a mounting plate support. The connecting base is installed at the bottom of the inner cavity of the mounting base. Two linear slide rails are installed parallel to each other on the top surface of the connecting base. A mounting plate is installed on the top surface of the linear slide rails. An electric rotating shaft is installed on one side of the top surface of the mounting plate. A support is connected to the top output end of the electric rotating shaft. A groove for mounting substrate is formed on the top surface of the support. Mounting brackets are installed on both sides of the mounting base via bolts. A vertically adjusting slide rod is installed inside the mounting bracket. An adjusting slider is installed on the surface of the adjusting slide rod. A rotating shaft is mounted on the surface of the adjusting slider via bearings. Rollers are provided on the surface of the rotating shaft.

[0005] Preferably, a linear motor is provided at the bottom of the mounting plate, and the linear motor is connected to the linear slide rail.

[0006] Preferably, the inner wall of the slotted cavity inside the bearing is uniformly provided with a plurality of clamping holes, wherein the diameter of the slot is smaller than the diameter of the substrate, and the bearing is made of silicone.

[0007] Preferably, a spring is sleeved on the outside of the connecting rod between the fixed seat and the platform plate.

[0008] Preferably, the rotating lead screw is provided with limiting slide bars on both sides of the platform plate surface, and the clamping plate is slidably connected to the limiting slide bars.

[0009] Preferably, mounting holes are provided on both sides of the bearing on the top surface of the mounting plate, and a fixing seat is installed on the top surface of the mounting hole by bolts. A connecting rod is connected to the top of the mounting seat, and a platform plate is sleeved on the surface of the connecting rod.

[0010] Preferably, a rotating screw is mounted on one side of the top of the platform plate via a bearing, a rotating handle is connected to the top of the rotating screw, and a clamping plate is threaded onto the surface of the rotating screw.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: During the film application process, the center of the roller first contacts the film and applies pressure. Then, the linear motor is activated, causing the mounting plate to move along the linear slide rail, driving the gas between the film and the substrate to both sides. Pressure is then applied to the outer side. This step-by-step pressure application method can more effectively expel gas and minimize the formation of air pockets. By setting connecting rods on both sides of the support, when applying the film to the substrate, both sides of one end of the film are fixed by clamps, ensuring that the unattached portion of the film maintains a certain angle with the substrate during the application process, guaranteeing separation from the substrate before pressing. This avoids premature and complete adhesion between the film and the substrate, preventing the gas from being trapped inside, thereby further reducing the possibility of air pockets, resulting in a smoother and tighter film application and improved film application quality.

[0018] Please see Figure 1-2 This utility model provides a technical solution: a film applicator, including a mounting base 1, a connecting base 2, a mounting plate 3, and a support 7. The connecting base 2 is installed at the bottom of the inner cavity of the mounting base 1. Two linear slide rails 4 are installed parallel to each other on the top surface of the connecting base 2. The mounting plate 3 is installed on the top surface of the linear slide rails 4. An electric rotating shaft 6 is installed on one side of the top surface of the mounting plate 3. The top output end of the electric rotating shaft 6 is connected to the support 7. The electric rotating shaft 6 is used to drive the substrate 9 to rotate after the film applicator is completed and the mounting plate 3 returns to its initial position. During the rotation, the electric rotating shaft 6 is started to cut off the excess film that exceeds the edge of the substrate 9 with a cutter. Mounting frames 10 are installed on both sides of the mounting base 1 by bolts. A vertical adjusting slide rod 11 is installed inside the mounting frame 10. An adjusting slider 12 is installed on the surface of the adjusting slide rod 11. A rotating shaft 13 is installed on the surface of the adjusting slider 12 through a bearing. A roller 14 is provided on the surface of the rotating shaft 13. The slider 12 is fixedly connected to the surface of the mounting frame by screws.

[0019] Furthermore, a linear motor 5 is provided at the bottom of the mounting plate 3, and the linear motor 5 is connected to the linear slide rail 4.

[0020] Furthermore, the inner wall of the slotted cavity inside the bearing 7 is evenly provided with several clamping holes 8, wherein the diameter of the slot is smaller than the diameter of the substrate 9. The bearing 7 is made of silicone. The substrate 9 is slightly larger in size. After being placed in the bearing 7, it is squeezed. These clamping holes 8 are deformed and reduced after being squeezed, which plays the role of fixing the substrate 9 of the film.

[0021] Furthermore, a spring 20 is sleeved on the outside of the connecting rod 19 between the fixed seat 18 and the platform plate 21.

[0022] Furthermore, limiting slide bars 23 are provided on both sides of the rotating lead screw 22 on the surface of the platform plate 21, and the clamping plate 24 is slidably connected to the limiting slide bars 23.

[0023] Furthermore, mounting holes 17 are provided on both sides of the bearing 7 on the top surface of the mounting plate 3. A fixing seat 18 is installed on the top surface of the mounting hole 17 by bolts. A connecting rod 19 is connected to the top of the mounting seat 1, and a platform plate 21 is sleeved on the surface of the connecting rod 19.

[0024] Furthermore, a rotating screw 22 is mounted on one side of the top of the platform plate 21 via a bearing. A rotating handle 16 is connected to the top of the rotating screw 22, and a clamping plate 24 is threaded onto the surface of the rotating screw 22.

[0025] In this invention, during the film application process, the center of the roller 14 first contacts the film and applies pressure. Then, the linear motor 5 is activated, causing the mounting plate 3 to move along the linear slide rail 14, driving the gas between the film and the substrate 9 to both sides. Pressure is then applied to the outer side of the roller 14. This step-by-step pressure application method more effectively expels the gas, minimizing the formation of air pockets. By setting connecting rods 19 on both sides of the support 7, when applying the film to the substrate 9, both sides of one end of the film are fixed by clamps 24, ensuring that the unattached portion of the film maintains a certain angle with the substrate 9 during the application process, guaranteeing separation from the substrate 9 before pressing. This prevents the film from prematurely and completely adhering to the substrate 9, thus trapping the gas inside and further reducing the possibility of air pockets, resulting in a smoother and tighter film application and improved film application quality.

[0026] 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.
