Description

Technical Field

[0001] This utility model relates to the field of film application equipment technology, and in particular to a film application machine pressing component that prevents air bubbles. Background Technology

[0002] The demand for surface coatings in the electronics industry is growing. In the production of electronic devices, screens of mobile phones, tablets and other devices need to be coated with protective films to prevent scratches, wear and fingerprints. To meet the large-scale and high-quality coating needs of these industries, coating machines are constantly developing, and the pressing components, as core components, are also constantly being improved and innovated.

[0003] To improve the protection of mobile phones and tablets, protective films are usually applied to the screen. The basic process of applying a protective film involves wiping the screen with wet and dry paper towels for initial cleaning, then using an adhesive to remove any remaining dust, and finally covering the screen with the protective film and using a squeegee to adhere the film to the screen. Generally, the entire process is performed by personnel, which is time-consuming, inefficient, and the film is prone to tilting during application. While there are some complex film application machines available, their application range is limited and their versatility is poor.

[0004] Existing patent (publication number: CN211105594U) discloses a highly efficient protective film application device. By rotating the second threaded rod, a roller can be moved up and down; by rotating the first threaded rod, a limiting plate can be moved back and forth; and by rotating the third threaded rod, the height of the adhesive tube can be adjusted. This allows the device to be used for applying screen protectors to mobile phones and tablets of various sizes and rear ends, expanding its application range. The device allows the mobile phone or tablet screen to be placed upwards and moved from the right end of the cleaning component to the left. The adhesive tube inside the cleaning component can adhere to the dust on the screen surface, eliminating the need for manual removal of dust particles and improving cleaning efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions. However, the pressing components of existing laminating machines are not well-suited for adapting to different types of objects. Excessive pressing pressure can easily lead to air bubbles and loose adhesion, affecting the quality of the lamination. Furthermore, it is not convenient to fix different types of objects, which can cause the objects to move during subsequent processing, resulting in misalignment between the film and the object, air bubbles, and reduced lamination efficiency.

[0006] To address this, a bubble-proof laminating machine pressing assembly is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a bubble-proof laminating machine pressing component, which can solve the problems of existing laminating machine pressing components being inconvenient to adapt to different types of objects, easily causing excessive pressing pressure leading to bubbles and loose adhesion, affecting the quality of laminating, and being inconvenient to fix different types of objects, which can easily cause the objects to move during subsequent processing, resulting in misalignment between the film and the object, generating bubbles, and affecting the efficiency of laminating.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application can effectively buffer the pressure generated when the top plate and the main pressure plate come into contact with the object to be laminated through the pressing component, making the pressing process more stable, ensuring uniform adhesion between the film and the object surface, greatly reducing the probability of air bubbles.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A bubble-proof laminating machine pressing assembly includes a worktable 1, a pressing assembly 4 disposed on the top of the worktable 1, and an adsorption assembly 5 disposed on the left side of the worktable 1.

[0029] The pressing assembly 4 includes a support frame 401 fixedly connected to the outside of the workbench 1. A hydraulic cylinder 402 is fixedly connected to the top of the support frame 401. A top plate 403 is fixedly connected to the output end of the hydraulic cylinder 402. Support rods 404 are movably connected to both sides of the top plate 403. The top of the support rods 404 passes through the support frame 401. A limit spring 405 is provided on the outside of the support rods 404. A main pressure plate 406 is fixedly connected to the bottom of the support rods 404. A secondary pressure plate 407 is rotatably connected to both sides of the main pressure plate 406.

[0030] In this embodiment: by activating the hydraulic cylinder 402, the output end of the hydraulic cylinder 402 begins to extend, driving the top plate 403, which is fixedly connected to it, to move downward. Then, the support rods 404, movably connected to both sides of the top plate 403, move downward along with the top plate 403. The top of the support rods 404 penetrates the support frame 401. During the downward movement, the main pressure plate 406 first contacts the object to be coated. As the hydraulic cylinder 402 continues to push the top plate 403 downward, the main pressure plate 406 generates an upward supporting force on the support rods 404, causing the support rods 404 to slide relative to each other inside the top plate 403. Simultaneously... The top plate 403 exerts pressure on the limiting spring 405 on the outside of the support rod 404. During the compression process, the limiting spring 405 can effectively buffer the impact force generated when the top plate 403 and the main pressure plate 406 come into contact with the object, avoiding excessive pressure from damaging the object or the film. The auxiliary pressure plates 407 rotatably connected to both sides of the main pressure plate 406 will automatically rotate and adjust on both sides of the main pressure plate 406 according to the shape of the object surface and the pressure distribution when the main pressure plate 406 comes into contact with the object, so as to better fit the object surface, ensure that the entire pressing process is more uniform and tight, and further reduce the possibility of air bubbles.

[0031] Specifically, such as Figure 3 , Figure 4As shown, the adsorption assembly 5 includes a slide rail 501 fixedly connected to the top of the workbench 1. A support base 502 is slidably connected to the top of the slide rail 501. A groove 503 is provided inside the support base 502. A rotary motor 504 is fixedly connected inside the groove 503.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, a fixed base 505 is fixedly connected to the output end of the rotary motor 504, and a vacuum generator 506 is fixedly connected to the outside of the fixed base 505.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, a vacuum adsorption platform 507 is bolted inside the fixed base 505, and the output end of the vacuum generator 506 is connected to the vacuum adsorption platform 507.

[0034] In this embodiment: by activating the vacuum generator 506, the vacuum generator 506 generates negative pressure inside the vacuum adsorption platform 507 through a pipe connected to the vacuum adsorption platform 507. This negative pressure is transmitted to the object to be coated through small holes on the platform, thereby firmly fixing the object to the vacuum adsorption platform 507 and ensuring that the object will not move arbitrarily during subsequent operations. Then, the rotary motor 504 is activated, and the output end of the rotary motor 504 drives the fixed base 505 to rotate. Since the vacuum adsorption platform 507 is bolted inside the fixed base 505, the vacuum adsorption platform 507 will rotate together with the fixed base 505, thereby achieving precise adjustment of the object's angle to ensure that the object is at the optimal angle during subsequent pressing processing, effectively preventing the formation of air bubbles due to angle deviation.

[0035] Specifically, such as Figure 4 As shown, a drive motor 2 is fixedly connected to the left side of the workbench 1, and a lead screw 3 is fixedly connected to the output end of the drive motor 2. A moving block 6 is threadedly connected to the outer side of the lead screw 3, and the moving block 6 is fixedly connected to the support base 502.

[0036] Specifically, such as Figure 2 As shown, sliding grooves 7 are provided on both sides inside the support frame 401. Limiting seats 8 are slidably connected inside the sliding grooves 7, and the limiting seats 8 are fixedly connected to the main pressure plate 406.

[0037] In this embodiment: By setting up a drive motor 2, a lead screw 3, and a moving block 6, during the film application preparation stage, the drive motor 2 on the left side of the workbench 1 is started. When the drive motor 2 runs, its output end drives the lead screw 3 to rotate synchronously. The moving block 6, threaded to the outside of the lead screw 3, moves linearly along the lead screw 3 due to its rotation. Since the moving block 6 is fixedly connected to the support base 502 of the adsorption assembly 5, the movement of the moving block 6 causes the support base 502 to slide on the slide rail 501 at the top of the workbench 1. By controlling the drive motor 2, precise... The position of the support base 502 is accurately adjusted, thereby adjusting the position of the vacuum adsorption platform 507 mounted on the support base 502. This moves the object to be coated on the vacuum adsorption platform 507 to a suitable position below the pressing assembly 4, improving the accuracy and efficiency of the operation. It can quickly position the object below the pressing assembly 4, while reducing poor coating conditions caused by object position deviations, such as misaligned coating or increased air bubbles. By setting the sliding groove 7 and the limiting seat 8, when the hydraulic cylinder 402 is activated and the output end pushes the top plate 403 downward, it... The support rod 404, which is movably connected to the top plate 403, moves downwards accordingly. The main pressure plate 406, fixedly connected to the bottom of the support rod 404, gradually approaches the object to be coated during descent. Since the limiting seat 8 is fixedly connected to the main pressure plate 406, and the limiting seat 8 slides within the sliding grooves 7 opened on both sides inside the support frame 401, the main pressure plate 406 can only move vertically downwards along the direction of the sliding grooves 7 during descent. After pressing is completed, the hydraulic cylinder 402 retracts, causing the top plate 403 to rise. The main pressure plate 406, driven by the support rod 404, moves upwards along the sliding grooves 7. The sliding groove 7 and the limiting seat 8 provide a stable guide for the main pressure plate 406, ensuring that the main pressure plate 406 is always perpendicular to the surface of the object to be coated during the pressing process. This effectively prevents the main pressure plate 406 from tilting during pressing and ensures that the pressure is evenly distributed on the surface of the film and the object during the pressing process. If the main pressure plate 406 is tilted, it will cause the film to not adhere tightly to some areas of the object, which is prone to generating air bubbles. The cooperation of the limiting seat 8 and the sliding groove 7 can greatly reduce the probability of this happening and improve the quality and success rate of film coating.

[0038] Specifically, such as Figure 5 As shown, a pressure sensor 9 is installed on the top of the main pressure plate 406, and a laser rangefinder sensor 10 is installed on the top of the support frame 401.

[0039] Specifically, such as Figure 1 As shown, the bottom of the workbench 1 is fixedly connected to a support leg 11, and the bottom of the support leg 11 is fixedly connected to a rubber foot pad 12.

[0040] In this embodiment: By setting a pressure sensor 9 and a laser rangefinder 10, during the operation of the pressing assembly 4, the pressure sensor 9 monitors the pressure between the main pressure plate 406 and the object to be coated in real time. The pressure sensor 9 converts the pressure data into an electrical signal and transmits it to the external control system. At the same time, the laser rangefinder 10 on the top of the support frame 401 continuously measures the distance from the top of the support frame 401 to the surface of the object to be coated, and also transmits the data to the control system. Based on this data, the control system adjusts the output pressure and stroke of the hydraulic cylinder 402 in real time. When the pressure sensor 9 detects excessive pressure, the control system will... The hydraulic cylinder 402 is controlled to reduce the output pressure, so that abnormalities in the pressing process can be detected and adjusted in time, thereby improving the quality of film application. It can better avoid air bubbles caused by uneven pressure or improper pressing position. At the same time, it can adapt to objects to be filmed and film materials of different thicknesses and materials, enhancing the versatility and adaptability of the equipment and broadening its application range. By setting support legs 11 and rubber feet 12, the rubber feet 12 increase the friction with the ground and reduce the vibration of the equipment during operation, which helps to ensure the precise movement of the pressing component 4 and the accuracy of film application, and avoids air bubbles caused by poor adhesion between the film and the object due to vibration.

[0041] Working Principle: During the application of the anti-bubble laminating machine's pressing assembly, the object to be laminated is placed on top of the vacuum adsorption platform 507. After placement, the vacuum generator 506 is activated. The vacuum generator 506, through a pipe connected to the vacuum adsorption platform 507, creates a negative pressure inside the platform. This negative pressure is transmitted to the object to be laminated through small holes on the platform, thus firmly fixing the object to the vacuum adsorption platform 507, ensuring that the object will not move during subsequent operations. Next, the rotary motor 504 is activated. The output of the rotary motor 504 drives the fixed base 505 to rotate. Since the vacuum adsorption platform 507 is bolted to the fixed base 505... Inside the 05, the vacuum adsorption platform 507 rotates together with the fixed base 505, thereby achieving precise adjustment of the object's angle to ensure that the object is at the optimal angle during subsequent pressing processing, effectively preventing air bubbles caused by angle deviation. Then, the drive motor 2 is started, and when the output end of the drive motor 2 rotates, it drives the lead screw 3 to rotate together. The lead screw 3 is threadedly connected to the moving block 6. Then, the rotation of the lead screw 3 will cause the moving block 6 to move along the axial direction of the lead screw 3. Because the moving block 6 is fixedly connected to the support base 502, and the support base 502 slides on the slide rail 501 on the top of the worktable 1, the movement of the moving block 6 will drive the support base 502 to move on the slide rail 501. Smoothly sliding, when the support base 502 moves to the bottom of the support frame 401, the drive motor 2 stops rotating. At this time, the object has been accurately moved to the appropriate position under the pressing assembly 4. Then, the hydraulic cylinder 402 is activated, and the output end of the hydraulic cylinder 402 begins to extend, driving the top plate 403, which is fixedly connected to it, to move downward. Then, the support rods 404, which are movably connected to both sides of the top plate 403, will move downward along with the top plate 403. The top of the support rods 404 penetrates through the support frame 401. During the downward movement, the main pressure plate 406 will first contact the object to be filmed. As the hydraulic cylinder 402 continues to push the top plate 403 downward, the main pressure plate 406 will exert upward support on the support rods 404. The supporting force causes the support rod 404 to slide relative to the top plate 403. At the same time, the top plate 403 will exert pressure on the limiting spring 405 on the outside of the support rod 404. During the compression process, the limiting spring 405 can effectively buffer the impact force generated when the top plate 403 and the main pressure plate 406 come into contact with the object, avoiding excessive pressure from damaging the object or the film. The auxiliary pressure plates 407 rotatably connected to both sides of the main pressure plate 406 will automatically rotate and adjust on both sides of the main pressure plate 406 according to the shape of the object surface and the pressure distribution when the main pressure plate 406 comes into contact with the object, so as to better fit the object surface, ensure that the entire pressing process is more uniform and tight, and further reduce the possibility of air bubbles.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
