[0001] The invention relates to the technical field of film pasting, and in particular discloses a universal automatic film pasting machine. Background Art

[0002] With the popularity of mobile terminal devices such as smartphones and tablets, the demand for screen protection films continues to increase. Screen protection films can effectively prevent mobile terminals from being damaged by external factors such as falls and scratches during daily use, thus extending the service life of the device. Therefore, many users choose to apply protective films to their mobile terminals to protect the integrity and aesthetics of the screen.

[0003] There are various models and types of mobile terminals, and especially with the development of technology, the thickness of different devices is becoming increasingly different. For example, smartphones are usually thinner, while some tablets or devices with protective cases are thicker. When applying the film manually, the operator needs to make height adjustments according to the thickness of different devices to ensure that the protective film can fit flatly with the screen surface. This adjustment mainly relies on manual experience, and the accuracy is difficult to guarantee, which can easily lead to the protective film not being able to completely cover the screen or the film material being offset, affecting the film application effect.

[0004] Existing automatic film laminating equipment still has shortcomings in adapting to mobile terminals of different thicknesses. For example, many devices lack a structure that can automatically adjust the height. When the thickness of the device varies greatly, the positioning and film laminating accuracy during the film laminating process are difficult to guarantee, resulting in unsatisfactory film laminating effects. Therefore, developing a universal automatic film laminating machine that can automatically adapt to mobile terminals of different thicknesses has become an urgent problem to be solved in the current technical field.

Through the adjustment of the first lifting mechanism 6, the film laminating machine of the present invention can be adjusted in height according to the thickness change of the mobile terminal to adapt to mobile terminals of different thicknesses without the need for complex manual adjustments, thereby improving the versatility and adaptability of the equipment; and the distance between the protective film 51 and the screen is always maintained at an optimal state, avoiding film offset or poor lamination problems caused by thickness differences.

[0035] The first lifting mechanism 6 includes a first motor 8 mounted on the housing 1, a push block 9 drivingly connected to the first motor 8, and a support frame 10 used in conjunction with the push block 9. The support frame 10 is slidably connected to the housing 1, and the support frame 10 is connected to the bearing mechanism 3. The first motor 8 drives the push block 9 to contact the support frame 10, and drives the support frame 10 to drive the bearing mechanism 3 to slide relative to the housing 1. The lifting and lowering movement of the mobile terminal is precisely controlled to ensure an appropriate distance between the mobile terminal and the film sticking mechanism 4 during the film sticking process.

[0036] The push block 9 is provided with an inclined guide surface 11 on one side close to the support frame 10, and the support frame 10 is provided with an inclined matching surface 12 that contacts the inclined guide surface 11. The push block 9 is slidably connected to the housing 1, and a screw is provided between the push block 9 and the first motor 8, which drives and connects the first motor 8. The first motor 8 drives the push block 9 to slide via the screw, and the sliding push block 9 drives the support frame 10 to move via the inclined guide surface 11 and the inclined matching surface 12. The design of the inclined surface makes the lifting movement smoother, reduces jitter or jamming, improves the smoothness and reliability of the system, simplifies the complex motion transmission mechanism through the mechanical structure, and improves the efficiency of the overall system.

[0037] Specifically, the sum of the angle between the inclined guide surface 11 and the horizontal plane and the angle between the inclined matching surface 12 and the horizontal plane is 180°.

[0038] The sensing element 7 is an infrared sensor or a pressure sensor. The infrared sensor or the pressure sensor is used to detect whether the protective film 51 reaches the specified position. When the sensing element 7 detects the existence of the protective film 51, it sends a signal to the control unit 5, and the control unit 5 starts the film sticking operation, effectively avoiding manual intervention and improving operation efficiency.

[0039] Specifically, in this embodiment, the sensing element 7 is an infrared sensor. When the lifting mechanism drives the supporting mechanism 3 to drive the external intelligent terminal and the external protective film 51 to reciprocate, the infrared sensor detects that the external protective film 51 reaches the infrared sensor or leaves the infrared sensor, and the infrared sensor transmits the signal to the control unit 5.

[0040] In another embodiment, the sensing element 7 is a pressure sensor, which is telescopically arranged in the casing 1. The pressure sensor extends out of the casing 1, and the lifting mechanism drives the supporting mechanism 3 to drive the external intelligent terminal and the external protective film 51 to reciprocate. When the external protective film 51 contacts the pressure sensor, the pressure sensor transmits a signal to the control unit 5 and retracts into the casing 1.

[0041] The automatic film laminating machine also includes an upper cover 2 installed on the top of the housing 1, and a UV curing device 13 and a second lifting mechanism 14 are arranged in the upper cover 2. An avoidance opening 15 is arranged on the upper cover 2, and the second lifting mechanism 14 drives the UV curing device 13 to extend out of the upper cover 2 through the avoidance opening 15. The UV curing device 13 is used to cure the glue on the protective film 51, so that the protective film 51 can be more firmly attached to the screen. UV curing ensures that the protective film 51 can be more firmly attached to the screen, improving the durability and stability of the film. The design of the second lifting mechanism 14 enables the UV curing device 13 to be raised and lowered as needed to avoid unnecessary UV irradiation damaging the equipment or film material.

[0042] Specifically, the second lifting mechanism 14 includes a first plate body 16, a second motor 17 installed on the first plate body 16, a second plate body 18 slidably connected to the first plate body 16, and a connecting rod assembly 19. A first gear 20 is installed on the output shaft of the second motor 17, and a first rack 21 meshing with the first gear 20 is provided on the second plate body 18; the second motor 17 drives the second plate body 18 to slide relative to the first plate body 16 via the first gear 20 and the first rack 21, and the sliding second plate body 18 drives the UV curing device 13 to extend out of the upper cover 2 through the avoidance opening 15 via the connecting rod assembly 19.

[0043] Specifically, the connecting rod assembly 19 includes a first rod body 22 and a second rod body 23 rotatably connected to the first rod body 22, one end of the first rod body 22 is rotatably connected to the second plate body 18, the other end of the first rod body 22 is rotatably connected to the upper cover 2, one end of the second rod body 23 is rotatably connected to the UV curing device 13, and the other end of the second rod body 23 is free.

[0044] The carrying mechanism 3 is provided with a mounting groove 24 for accommodating an external mobile terminal. The UV curing device 13 includes a sealing member 25 and a UV light plate 26 installed on the sealing member 25. The sealing member 25 cooperates with the mounting groove 24 to form an accommodating space.

[0045] The housing 1 is provided with a vacuum pump 27, which is connected to the accommodating space. The sealing member 25 and the mounting groove 24 form a closed accommodating space, and the vacuum pump 27 extracts the air in the accommodating space to form a negative pressure environment to eliminate bubbles that may appear during the film laminating process, ensure the laminating flatness of the film, improve the visual quality of the film laminating effect, and reduce defects.

[0046] Specifically, the sealing member 25 is a lampshade that is sealed with the mounting groove 24, and a transparent silicone sealing soft film is provided on the side of the lampshade close to the mounting groove 24. The lampshade is sealed with the mounting groove 24 to ensure that the external environment is isolated from the internal film-applying space. The transparent silicone sealing soft film further enhances the sealing effect, making the operating environment during the laminating process of the protective film 51 cleaner and dust-free, preventing dust or impurities from entering, ensuring the cleanliness and effect of the film, and UV light can pass through the silicone soft film directly to the mobile terminal screen to complete the curing process of the protective film 51, ensuring the quality and firmness of the film.

[0047] Specifically, a contact switch 46 is provided on one side of the seal 25 close to the mounting groove 24, and the contact switch 46 is electrically connected to the control unit 5. The second lifting mechanism 14 drives the UV curing device 13 to extend out of the upper cover 2 through the avoidance opening 15, and the seal 25 extends into the mounting groove 24 to form a closed accommodation space with the mounting groove 24. The contact switch 46 on the seal 25 contacts the external protective film 51 in the accommodation space and transmits the signal to the control unit 5, and the control unit 5 controls the second lifting mechanism 14 to stop working. Through the cooperation of the contact switch 46 and the control unit 5, the contact state between the protective film 51 and the mobile terminal can be accurately monitored, and the action of the second lifting mechanism 14 can be controlled in combination with the control unit 5 to avoid the UV curing device 13 from causing damage to the mobile terminal such as crushing. This design improves the intelligence and automation of the film pasting process, ensures the quality of the film pasting, and also improves the safety of operation and the durability of the equipment.

[0048] Specifically, the contact switch 46 is provided with multiple groups, and the multiple groups of contact switches 46 are arranged on the sealing member 25 at equal intervals. Through the synchronous monitoring of the multiple groups of contact switches 46, the control unit 5 can more accurately control the lifting process of the UV curing device 13. Once all switches detect contact, the lifting mechanism will stop immediately to avoid excessive pressure on the mobile terminal, prevent the equipment from being crushed due to local uneven force, and improve the safety of operation; at the same time, the multiple groups of contact switches 46 can provide contact signals at multiple points in real time, and the system can automatically analyze whether the protective film 51 is completely attached to the screen, without manual intervention for film monitoring, which greatly improves the degree of automation and simplifies the operation process; and the design of the multiple groups of contact switches 46 can adapt to mobile terminal screens of different sizes and shapes, especially for some devices with larger screens or irregular shapes, the distributed monitoring of the multiple groups of switches can ensure that the protective film 51 can be evenly attached to various screens.

[0049] The film sticking mechanism 4 includes a film sticking assembly 28, which includes a movable frame, a resistance member 30 rotatably connected to the movable frame, a film sticking motor 31 installed on the housing 1, and a transmission assembly 32. The film sticking motor 31 is connected to the movable frame via the transmission assembly 32, and the film sticking motor 31 drives the movable frame to move via the transmission assembly 32. The resistance member 30 resists the external protective film 51 and sticks the protective film 51 on the screen of the external mobile terminal. The mechanical transmission system can perform the film sticking operation evenly and smoothly, reduce errors caused by human operation, improve operation efficiency, and reduce human intervention.

[0050] Specifically, the transmission assembly 32 includes a first rotating shaft 33 rotatably connected to the housing 1, a second rotating shaft 34 rotatably connected to the housing 1, and a transmission belt 35. The first rotating shaft 33 drives the film-sticking motor 31. The first rotating shaft 33 is connected to the second rotating shaft 34 via the transmission belt 35. The movable frame is connected to the transmission belt 35. The film-sticking motor 31 drives the first rotating shaft 33 to rotate and drive the transmission belt 35. The transmission belt 35 drives the movable frame to move. The abutment 30 abuts against the external protective film 51 and sticks the protective film 51 on the screen of the external mobile terminal.

[0051] Specifically, the abutment 30 includes a shaft 47, a roller 48 disposed on the shaft 47, and a buffer 49. The outer diameter of the roller 48 is greater than the outer diameter of the shaft 47. The buffer 49 is wrapped around the outer side of the abutment 30. The buffer 49 abuts against the external protective film 51 and attaches the protective film 51 to the screen of the external mobile terminal. By disposing the roller 48 between the buffer 49 and the shaft 47, the thickness of the buffer 49 is reduced, and the problem that when the buffer 49 is thick, the buffer 49 is greatly deformed, the protective film is unevenly pressed, and bubbles are easily generated is solved.

[0052] Specifically, the roller body 48 and the shaft body 47 are of an integrated structure, and the buffer part 49 is made of plastic, and the buffer part 49 is injection molded to cover the outer side of the abutment 30. The integrated structure is convenient for production and processing. When applying the film, the roller body 48 and the shaft body 47 are firmly connected, and it is not easy to shake and cause uneven pressure on the protective film 51; plastic is easy to process and shape, which reduces production costs.

[0053] Specifically, the buffer portion 49 is made of soft rubber. The soft rubber prevents the abutment member 30 from scratching the protective film 51, and the highly elastic soft rubber is deformed under pressure, and the deformed buffer portion 49 releases elastic potential energy to squeeze out bubbles, thereby improving the film sticking effect.

[0054] In a further technical solution, the roller body 48 is provided with gradually thickened curved sections at both ends in the direction away from the middle, the shape and structure of the buffer portion 49 is consistent with the shape and structure of the roller body 48, and the curved section is used to resist the arc portion of the edge of the external mobile terminal screen. The external protective film 51 is more closely fitted to the edge of the external mobile terminal screen, so that the film laminating machine is suitable for laminating on curved screens, increasing the scope of use of the equipment and solving the problem of the screen edge not being closely fitted and bubbles being easily generated during film laminating.

[0055] The film-applying mechanism 4 further includes a winding assembly 36, which is used to roll up the dust removal film 53 of the external protective film 51. The winding assembly 36 includes a winding motor 37 mounted on the housing 1, and a winding roller 38 drivingly connected to the winding motor 37. The winding roller 38 is rotatably connected to the housing 1. The winding motor 37 drives the winding roller 38 to rotate, and the rotating winding roller 38 separates the dust removal film 53 from the protective film 51 via the pull strip of the rolled dust removal film 53. Automatic winding avoids the step of manually removing the dust removal film 53, improves the film-applying efficiency, prevents the dust removal film 53 from remaining, and ensures the transparency and cleanliness of the protective film 51.

[0056] In the process of applying film to the screen of a mobile terminal, some users need to tear off the plastic strip of the dust removal film 53 on the back of the protective film 51, and then apply the protective film 51 to the screen surface. After the dust removal film 53 on the back is torn off, the protective film 51 is easily printed with fingerprints or stained with other dust during the pasting process, which can easily make the film dirty, affecting the appearance, and easily generating bubbles, affecting the film application effect; at the same time, the operation is complicated, and the operating proficiency of the film application personnel is required to be high. By setting the winding component 36, the protective film 51 is simultaneously attached to the screen of the mobile terminal and the dust removal film 53 is separated from the protective film 51, the generation of bubbles is avoided, the film application operation is simpler, and the film application efficiency and quality are improved.

[0057] The bearing mechanism 3 includes a fixture body 39, a clamping and positioning assembly 40 movably mounted on the fixture body 39, a mounting groove 24 is provided on the fixture body 39, an external mobile terminal is placed in the mounting groove 24, and the clamping and positioning assembly 40 cooperates with the mounting groove 24 to clamp the external mobile terminal. The clamping and positioning assembly 40 cooperates with the mounting groove 24 to accurately position and fix the mobile terminal, ensuring stability and accuracy during the film laminating process; at the same time, the film laminating machine can adapt to mobile terminals of different sizes, and has a wide range of applicability.

[0058] Specifically, the clamping and positioning assembly 40 includes a third motor 41 installed at the bottom end of the inside of the jig body 39, a first driven plate 42 slidably connected to the jig body 39, a first clamping plate 43 connected to the first driven plate 42, and a second gear 44 installed on the axis of the third motor 41. The first driven plate 42 is provided with a second rack 45 meshing with the second gear 44. The third motor 41 drives the first driven plate 42 to slide relative to the jig body 39 via the second gear 44 and the second rack 45. The first driven plate 42 drives the first clamping plate 43 to contact the external mobile terminal. The first clamping plate 43 cooperates with the mounting groove 24 to clamp the external mobile terminal.

[0059] Specifically, the fixture body 39 is provided with a positioning column 50 which is protruded from the fixture body 39, and a dust removal film 53 with a pull strip on the outside is attached to one side of the external protective film 51, and a positioning film 52 is attached to the other side of the protective film 51. The positioning film 52 is provided with a positioning hole which is adapted to the positioning column 50, and the positioning film 52 is mounted on the positioning column 50 through the positioning hole to limit the movement of the protective film 51.

[0060] Specifically, the clamping and positioning components 40 are provided with two groups, and the two groups of clamping and positioning components 40 respectively clamp the two adjacent sides of the external mobile terminal. The double groups of clamping components enable the mobile terminal to be more firmly maintained in the correct position, reduce the swing or displacement of the device, improve the film sticking accuracy, and further reduce the error during the operation.

[0061] Specifically, the upper cover 2 is provided with a touch screen, which is electrically connected to the control unit 5. The setting is performed through the touch screen according to the type of the external protective film 51 inserted. When a dust removal film 53 is provided on the external protective film 51, the winding component 36 is started, and when there is no dust removal film 53 on the external protective film 51, the winding component 36 is closed.

[0062] In this embodiment, a mobile terminal (such as a mobile phone or a tablet) that needs to be film-coated is placed in the mounting groove 24 on the bearing mechanism 3, and an external protective film 51 is placed in a corresponding position of the film-coating mechanism 4. Usually, a dust removal film 53 with a pull strip on the outside is attached to one side of the external protective film 51, and a positioning film 52 is attached to the other side of the protective film 51. The positioning film 52 is provided with a positioning hole adapted to the positioning column 50.

The clamping positioning assembly 40 cooperates with the mounting groove 24 to clamp the external mobile terminal. The first lifting mechanism 6 drives the bearing mechanism 3 to move up and down, and adjusts the height of the mobile terminal so that it is in an appropriate fitting position with the film-coating mechanism 4. The sensor 7 detects the position of the protective film 51 and sends a signal to ensure that the protective film 51 is aligned with the screen of the mobile terminal. The control unit 5 controls the first upgrading mechanism to stop moving, and the control unit 5 The second lifting mechanism 14 is controlled to drive the UV curing device 13 to extend from the avoidance opening 15 of the upper cover 2 to ensure that the UV light can irradiate the protective film 51. The UV curing device 13 forms a closed space through the sealing member 25. The contact switch 46 detects the external protective film 51 and sends a signal. The second upgrading mechanism is controlled to stop moving through the control unit 5. The vacuum pump 27 starts to work, so that the UV curing device 13 forms a closed space through the sealing member 25 in a vacuum state. The film pasting mechanism 4 drives the resistance member 30 through the transmission component 32 to flatly paste the protective film 51 on the screen of the mobile terminal. While the film pasting mechanism 4 is pasting the film, the winding motor 37 drives the winding roller 38 to rotate. The rotating winding roller 38 separates the dust removal film 53 from the protective film 51 through the pull strip of the dust removal film 53. After the film pasting is completed, the UV light plate 26 emits ultraviolet light to the surface of the protective film 51 to cure it and enhance the adhesion of the film material. The upper cover 2 is opened, the positioning film 52 is torn off, and the mobile terminal is taken out.
