Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone film pasting, and in particular discloses a universal film pasting device. Background Art

[0002] With the rapid development of electronic technology, electronic devices are becoming increasingly popular, especially the use of smart phones is increasing year by year. In order to protect the screen of the mobile phone, people usually need to attach a protective film on the screen of the mobile phone, and because the screen sizes of smart phones are different.

[0003] As a result, mobile phone screen protectors come in a variety of sizes and types, and materials include tempered films, high-definition films, frosted films, anti-blue light films, etc., and each material has different characteristics and advantages. Existing mobile phone screen protectors are usually designed for a specific model or size of mobile phone, and are difficult to adapt to mobile phones of different sizes, shapes or brands. This requires users to purchase a dedicated screen protector for each device, increasing the cost of use. Protective films of different materials, such as tempered films and flexible films, have different requirements for pressure and speed during the lamination process, and most current screen protectors cannot be adjusted according to the material properties of the protective film, resulting in problems such as poor lamination, residual bubbles or damage to the film material during the lamination process. Although many automatic screen protectors can improve the accuracy of screen protectors, their structural design is relatively complex and inconvenient to debug. Users need to be familiar with the operation of the equipment, which makes the user experience less user-friendly for ordinary consumers. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0035] See also Figures 1 to 10 As shown, please refer to the utility model Figure 1As shown in the figure, a universal film-sticking device of the present invention includes a workbench 1, a film-sticking actuator 2 arranged on the workbench 1; it also includes a carrier frame 10 and a first lifting mechanism 4 used in conjunction with the film-sticking actuator 2, the first lifting mechanism 4 is used to drive the carrier frame 10 to move up and down relative to the workbench 1 to cooperate with smart terminals with different thicknesses; the workbench 1 is provided with a first sensor 5 and a central controller, the central controller is connected to the first lifting mechanism 4 and the film-sticking actuator 2, the first sensor 5 is used to detect the position signal of the screen of the smart terminal carried by the carrier frame 10 and transmit it to the central controller, the central controller controls the first lifting mechanism 4 to stop the action according to the position signal detected by the first sensor 5, and controls the film-sticking actuator 2 to stick the external protective film on the screen of the smart terminal carried by the carrier frame 10 after processing by the first lifting mechanism 4.

[0036] Specifically, the universal film-sticking device also includes a positioning mechanism 3 arranged in cooperation with the carrying frame 10. The positioning mechanism includes a first limit member 32 and a second limit member 34 arranged to move back and forth relative to the carrying frame 10, and a first driving member 31 and a second driving member 33 respectively used to drive the first limit member 32 and the second limit member 34. The moving directions of the first limit member 32 and the second limit member 34 are arranged to cross each other and are used to respectively contact the adjacent two sides of the smart terminal to limit it in the carrying frame 10.

[0037] During use, first, the smart terminal is placed on the carrier frame 10 so that the two sides of the smart terminal respectively contact the two sides of the carrier frame 10. Then, the positioning mechanism 3 is activated, and the first driving member 31 and the second driving member 33 respectively drive the first limiting member 32 and the second limiting member 34 to move to the other two sides of the smart terminal. Since the movement directions of the two are intersecting, they firmly clamp the smart terminal in the carrier frame 10, ensuring that the position of the smart terminal remains stable during the film application process. After the smart terminal is locked, the first lifting mechanism 4 raises or lowers the carrier frame 10 according to the thickness of the smart terminal to facilitate the film application action of the film application actuator 2. When the screen of the smart terminal is in a suitable fitting position, the operator places the external protective film on the screen of the smart terminal with the help of the carrier frame 10 or other positioning structures (the protective film here can completely remove the release film or partially remove the release film). The film application actuator 2 starts working, and the fourth driving member 21 drives the film application member 22 to move back and forth to contact the protective film to expel the air between the protective film and the screen and evenly apply the protective film to the screen.

[0038] In this embodiment, the first and second drive members 31 and 33 are rotary motors that respectively drive the reciprocating movement of the first and second stoppers 32 and 34 via a rack-and-pinion transmission mechanism 30. In practice, this can be achieved using a servo motor in conjunction with a screw module 42. The first lifting mechanism uses a rotary motor in conjunction with a screw module 42 to drive the lifting and lowering of the carrier frame 10, while the fourth drive member 21 drives the film applicator 22 via a gear and belt transmission mechanism. These three approaches offer simple and reliable structures, stable operation, and flexible adjustment for smart terminals of varying sizes, enhancing the versatility and flexibility of the device.

[0039] Specifically, the first lifting mechanism 4 includes a third driving member 41 provided on the workbench 1, a screw module 42 connected to the third driving member 41, a second sliding plate 43 provided at the output end of the screw module 42, and a movable frame 44 provided on the workbench 1 for reciprocating movement;

[0040] The carrying frame 10 is reciprocally movable on the workbench 1 via the movable frame 44 . The second sliding plate 43 is provided with a first inclined guide surface 431 , and the movable frame 44 is provided with a second inclined guide surface 441 that matches the first inclined guide surface 431 .

[0041] The third driving member 41 drives the second sliding plate 43 to move back and forth via the screw module 42. The first inclined guide surface 431 of the reciprocating second sliding plate 43 contacts the second inclined guide surface 441 to drive the movable frame 44 to move up and down. The movable frame 44 is used to link the carrying frame 10 and the smart terminal it carries to move up and down to cooperate with the film-sticking action of the film-sticking actuator 2.

[0042] Specifically, the first lifting mechanism 4 adopts a third driving member 41 (such as a servo motor or a stepper motor) as a power source, and is directly connected to the screw module 42 through a high-precision coupling. The screw module 42 is composed of a screw, a nut seat and a guide assembly to ensure stable linear motion output. A second sliding plate 43 is fixedly installed at the output end of the screw module 42, and a first inclined guide surface 431 is designed on the plate, which is inclined to the horizontal plane at a specific angle (such as 45°). A movable frame 44 is installed on the workbench 1, and reciprocating movement in the horizontal direction is achieved through guide rails or linear bearings, and a second inclined guide surface 441 that cooperates with the first inclined guide surface 431 is provided at its corresponding position. The sum of the angles between the two is 180°, forming a complementary inclined surface structure.

[0043] When the third drive member 41 is activated, rotating the screw module 42, the nut seat drives the second sliding plate 43 to move axially along the screw. Due to the close contact and interaction between the first inclined guide surface 431 and the second inclined guide surface 441, the horizontal movement of the second sliding plate 43 is converted into vertical movement of the movable frame 44. The carrier frame 10, fixed above the movable frame 44, thus moves the smart terminal up and down as the movable frame 44 rises and falls, coordinating the film application action of the film application component 22 in the film application actuator 2.

[0044] The ingenious design of the inclined guide surface enables the transition from horizontal movement to vertical lift, eliminating the need for an additional lifting mechanism. This effectively saves equipment space and makes the overall structure more compact and rational. Because the lifting range can be adjusted as needed, the mechanism can adapt to smart terminals of different sizes and shapes, improving the versatility and flexibility of the equipment and meeting diverse production needs.

[0045] The central controller is connected to the third driver 41. When the first sensor 5 detects that the smart terminal on the carrier frame 10 has moved to a preset position, the central controller controls the third driver 41 to stop. This design avoids positioning errors caused by overshoot or undershoot of the carrier frame 10, effectively improving the positioning accuracy of the film application process. In actual production, the first sensor 5 can also be replaced with a pressure sensor or distance sensor.

[0046] Specifically, the film-sticking actuator 2 includes a film-sticking part 22 that is arranged to move back and forth relative to the supporting frame 10 and a fourth driving part 21 connected to the film-sticking part 22. The fourth driving part 21 is used to drive the film-sticking part 22 to move back and forth to contact the external protective film and stick it on the screen of the external smart terminal in the supporting frame 10.

[0047] Specifically, the film sticking member 22 includes a film sticking bracket 221 and a film sticking roller 222 rotatably arranged on the film sticking bracket 221. The fourth driving member 21 is connected to the film sticking bracket 221 and is used to drive the film sticking bracket 221 to move from one end of the carrying frame 10 to the other end of the carrying frame 10 so as to cross the screen of the smart terminal carried by the carrying frame, so that the film sticking roller 222 rolls against the external protective film on the smart terminal to stick it on the screen of the smart terminal.

[0048] The film-applying roller 222 is mounted on the film-applying bracket 221 via a rotating device such as a bearing or a sleeve, ensuring that it can roll freely when subjected to external forces. The film-applying roller 222 is a flexible silicone roller or a metal rod and a cylindrical silicone member wrapped around the metal rod to avoid damage to the protective film and the screen of the smart terminal. An automated film-applying method is adopted, with the fourth drive member 21 driving the film-applying bracket 221 to move back and forth and the film-applying roller 222 to roll against the protective film, achieving a fast and accurate film-applying process. Compared with manual film-applying, this greatly improves production efficiency and film-applying accuracy.

[0049] Specifically, the fourth drive member 21 uses a gear belt transmission structure to drive the film holder 221. The fourth motor 211 is firmly mounted on the workbench 1. The motor serves as a power source and is connected to one of the first gear set 212 or the second gear set 213 via a coupling or direct connection. The first gear set 212 and the second gear set 213 are respectively located at both ends of the length direction of the carrier frame 10, and each includes one or more groups of mutually meshing gears to achieve power transmission and speed / torque adjustment. A high-strength and wear-resistant transmission belt 214 is selected. The inner side of the belt is provided with a tooth shape that matches the first gear set 212 and the second gear set 213 to ensure that the belt can run stably and accurately during the transmission process. The belt is sleeved on the first gear set 212 and the second gear set 213 to form a closed-loop transmission system. The film holder 221 is firmly connected to the transmission belt 214 by a clamp, a buckle or other fixing device. In this way, when the transmission belt 214 moves under the drive of the gear set, the film holder 221 will move back and forth accordingly.

[0050] By adjusting the gear ratio and motor speed, the system can flexibly adapt to the film application needs of smart terminals of different sizes and models. Furthermore, the transmission structure provides a certain degree of cushioning and shock absorption, helping to protect the smart terminal and film application equipment from impact and vibration.

[0051] Specifically, the film-laminating actuator 2 also includes a plurality of diaphragm positioning columns 23 arranged on the workbench 1. The positioning film of the external protective film has a positioning hole for accommodating the diaphragm positioning columns 23. The external protective film is positioned on the screen of the smart terminal via the positioning film and the diaphragm positioning columns 23; the plurality of diaphragm positioning columns 23 are respectively arranged at the starting end and the ending end of the movement of the film-laminating roller 222, and the height of the diaphragm positioning column 23 at the starting end is lower than the height of the diaphragm positioning column 23 at the ending end.

[0052] A plurality of film positioning posts 23 are respectively mounted on the workbench 1 at the starting and ending ends of the film laminating roller 222. The height of the film positioning posts 23 at the starting end is set to be relatively low so as to provide slight support and positioning when the external protective film initially contacts the screen of the smart terminal; the height of the film positioning posts 23 at the ending end is set to be relatively high to ensure that during the rolling process of the film laminating roller 222, the protective film is gradually and slowly attached to the screen by means of the height difference between the starting and ending ends. This process can significantly eliminate possible bubbles or wrinkles. The film positioning posts 23 in this embodiment are of a movable design and are detachably connected to the workbench 1. For protective films of different sizes for smart terminals of different sizes, the spacing between two adjacent film positioning posts 23 can be adjusted to meet the film laminating requirements.

[0053] Specifically, the film-laminating actuator 2 also includes a winding assembly 24 used in conjunction with the film-laminating member 22. A winding cover 240 is provided on the workbench 1, and the winding assembly 24 is installed in the winding cover 240. The winding assembly 24 includes a winding roller 242 rotatably arranged on the winding cover 240 and a fifth driving member 241 connected to the winding roller 242. The fifth driving member 241 is used to drive the winding roller 242 to rotate to rewind the release film that has been peeled off from the external protective film affixed to the screen of the smart terminal. The starting positions of the winding roller 242 and the film-laminating roller 222 are respectively located at the two ends of the length direction of the workbench 1, and the winding roller 242 is provided with an adhesive member (which can be a single-sided tape detachably wound on the winding roller 242).

[0054] During use, the protective film can be attached to the smart terminal after removing part of the release film, and the removed part of the release film is connected to the take-up roller 242 through the adhesive member, and the take-up direction of the release film is parallel to the moving direction of the film holder 221. When the film holder 221 drives the film roller 222 to perform the film application action, the release film is reeled under the action of the take-up roller 242. The coordination of the film application part 22 and the take-up component 24 in time and space ensures the smooth progress of the entire film application process, while avoiding the generation of bubbles between the protective film and the screen as much as possible (if the protective film is directly removed and attached to the screen of the smart terminal, a large amount of air will enter between the protective film and the screen, generating too many bubbles and affecting the film application effect).

[0055] Specifically, the workbench 1 includes a lower shell 11 and an upper shell 12 rotatably arranged on the lower shell 11, the lower shell 11 has a accommodating cavity 111 for accommodating the carrying frame 10, the film actuator 2, the positioning mechanism 3 and the first lifting mechanism 4; a sealing member 121 is reciprocatingly arranged on the upper shell 12, and the upper shell 12 rotates relative to the workbench 1 so that the sealing member 121 extends into the accommodating cavity 111 and interference fits with the lower shell 11 to form a sealed environment for use with the film actuator 2.

[0056] Specifically, the workbench 1 adopts a split structure, consisting of a lower shell 11 and an upper shell 12. As the main part, the lower shell 11 has sufficient strength and rigidity to support the entire film actuator 2, the positioning mechanism 3, the first lifting mechanism 4 and other key components. A accommodating chamber 111 is provided in the lower shell 11 to accommodate and protect these mechanisms and prevent adverse factors such as external dust and moisture from affecting the equipment. The upper shell 12 is mounted on the lower shell 11 through rotating connectors such as bearings and rotating shafts to achieve the function of relative rotation. This design allows the upper shell 12 to rotate relative to the lower shell 11 when needed, thereby changing the working state of the workbench 1 or accessing the components in the accommodating chamber 111.

[0057] When the upper shell 12 is rotated to a specific position relative to the lower shell 11 (such as completely covering the opening of the accommodating chamber 111), the seal 121 extends into the accommodating chamber 111 and contacts the inner wall of the lower shell 11, thereby closing the opening part of the accommodating chamber 111. At this time, the interior of the accommodating chamber 111 is isolated from the external environment, forming a relatively closed and clean working environment, which is conducive to the stable operation and extended service life of the film actuator 2. The design of the sealed environment also plays a role in protecting the internal mechanism of the equipment. In particular, for some precision components (such as sensors, motors, etc.), they are protected from external impacts and pollution, thereby extending the service life of the equipment. The design of the sealed environment also plays a role in protecting the internal mechanism of the equipment. In particular, for some precision components (such as sensors, motors, etc.), they are protected from external impacts and pollution, thereby extending the service life of the equipment.

[0058] Specifically, a UV light source 122 (such as a UV lamp tube or UV lamp panel) and a second lifting mechanism 6 are disposed within the upper housing 12 to provide the necessary ultraviolet radiation during the film application process to achieve a specific curing or cross-linking effect in conjunction with the external UV film. The UV light source 122 is fixedly connected to the sealing member 121. The second lifting mechanism 6 includes a first sliding plate 63 that is reciprocally mounted on the upper housing 12, a sixth driving member 61 for driving the first sliding plate 63, and a transmission assembly 62 connected between the first sliding plate 63 and the sealing member 121.

[0059] The first sliding plate 63 is mounted on the upper housing 12 via a slide rail or guide mechanism, enabling linear reciprocating motion in a specific direction (e.g., horizontally). A sixth driving member 61 (e.g., a servo motor, stepper motor, etc.) is connected to the first sliding plate 63 via a speed reducer or direct connection, providing the power for linear motion.

[0060] The transmission assembly 62 consists of a first transmission rod 621 and a second transmission rod 622, which are connected by a rotational connection to achieve force transmission and direction conversion. One end of the first transmission rod 621 is rotationally connected to the first sliding plate 63, and the other end is rotationally connected to the seal 121. The second transmission rod 622 has one end rotationally connected to the top of the upper housing 12 and the other end is slidably mounted on the bottom of the seal 121 (this can be achieved through a sliding groove, slider, or other structure), allowing it to rotate and move within a certain range.

[0061] When the sixth drive member 61 drives the first sliding plate 63 to move linearly back and forth, the transmission assembly 62 converts the linear motion into rotational motion, and further converts the rotational motion into the lifting and lowering motion of the sealing member 121. This conversion mechanism ensures that the UV light source 122 can move up and down according to the predetermined trajectory and speed to match the film application process;

[0062] A transparent silicone membrane is installed on the end of the seal 121 away from the UV light source 122. This membrane not only maintains the sealed environment of the accommodating chamber 111, but also allows the light from the UV light source 122 to penetrate and illuminate the external UV film, achieving a curing or cross-linking effect. Furthermore, the transparency and flexibility of the silicone membrane ensures a good sealing effect and light transmission performance.

[0063] Specifically, the universal film laminating device further includes a PCB control board 7 disposed on a workbench 1, a central controller connected to the PCB control board 7, and a touch screen connected to the central controller; the film laminating actuator 2, the positioning mechanism 3, the first lifting mechanism 4, the second lifting mechanism 6, and the air pump 112 are all connected to the central controller via respective interfaces. In this embodiment, second sensing elements 13 are provided at both ends of the film laminating bracket 221, the first sliding plate 63, and the second sliding plate 43 in the direction of movement. Similarly, a second sensing element 13 is also provided at the end of the sealing element 121 close to the silicone diaphragm. These second sensing elements 13 can be proximity switches, pressure sensors, or position sensors, and are all connected to the central controller via wireless connections (Wi-Fi, Bluetooth, Zigbee, etc.). The central controller controls the movement positions of the components detected by the second sensing elements 13 and coordinates them to perform the film laminating operation.

[0064] The touchscreen, the primary interface for human-machine interaction, is directly connected to the central controller. Users input commands or select operating modes via the touchscreen. The central controller interprets these inputs to generate corresponding control signals and sends them to the various actuators. Based on pre-set programs or user-input control commands, the central controller coordinates the timing and positional relationships of the various actuators, ensuring they work together to complete the film application task.

[0065] For example, in the film pasting process, the positioning mechanism 3 first fixes the screen of the smart terminal, and then the first lifting mechanism 4 controls the carrier frame 10 to rise or fall to a suitable position according to the position signal transmitted by the first sensing member 5. Then the operator positions the external protective film on the screen of the smart terminal through the positioning film and the film positioning column 23, and then removes the positioning film. Then, the upper shell 12 is rotated so that it covers the lower shell 11. At this time, the second lifting mechanism 6 drives the sealing member 121 to seal the accommodating cavity 111 of the lower shell 11, and links the UV light source 122 to move downward (if the external protective film is a UV film, the central control system controls the UV light source 122 to irradiate the UV film to cure it according to the instructions input by the user through the touch screen) to a predetermined height for ultraviolet irradiation to cure the UV film; then, the film pasting actuator 2 starts to work, and the film pasting roller 222, driven by the fourth driving member 21, rolls the protective film placed on the screen of the smart terminal to expel the bubbles between the two and attach the protective film to the screen; finally, the upper shell 12 is opened, the positioning mechanism 3 releases the smart terminal, and the operator takes out the mobile phone, completing a film pasting action.

[0066] In this embodiment, a power module is provided in the accommodating cavity 111 of the lower shell 11, and the power module is electrically connected to the power units of the PCB control board 7, the first lifting mechanism, the second lifting mechanism 6, the positioning mechanism 3, the film-sticking actuator 2, the UV lamp light source 122, and the air pump 112 to supply power to each mechanism. In order to enhance the flexibility and portability of the device, a Type-C interface 8 is provided on the outside of the lower shell 11, which is directly connected to the internal power module. Users can achieve plug-and-play through this interface and quickly power the device; at the same time, a rechargeable battery pack is integrated inside the device, allowing users to charge the battery through an external power adapter (via the Type-C interface 8), realizing a post-storage use mode, getting rid of the constraints of the power cord, and improving the convenience of operation.
