Currently, the mechanical structure of the positioning device of a fully automatic film applicator is relatively fixed in design, with integrated molds and guide rails and sliders of specific specifications. Changing the size or spacing of these components without large-scale modifications limits the adaptability of the positioning device to products of different sizes. Existing solutions design the positioning device to consist of multiple replaceable modules. For products of different sizes, only the corresponding modules need to be replaced without large-scale modifications to the entire positioning device. However, in order to adapt to various product sizes, multiple modules of different specifications need to be prepared, resulting in frequent module replacements during positioning, thus reducing versatility.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a positioning device for a fully automatic film applicator, comprising a fixed base 1 and two rotary valves 4. A bidirectional threaded rod 3 is rotatably connected to the front and rear sides of the inner wall of the fixed base 1. The rotatable connection of the bidirectional threaded rod 3 allows free rotation within the fixed base 1. The right end of the outer wall of the front bidirectional threaded rod 3 is fixedly connected to the rotary valve 4, and the left end of the outer wall of the rear bidirectional threaded rod 3 is fixedly connected to the rotary valve 4. When the operator rotates the rear rotary valve 4, the left end of the outer wall of the rear bidirectional threaded rod 3 is fixedly connected to the rotary valve 4. Multiple clamping blocks 5 are provided on the front side of the top center of the fixed base 1. The clamping blocks 5 are used to clamp and fix the film applicator. The bottom of the inner walls of the multiple clamping blocks 5 are threaded to the left and right sides of the outer walls of the two clamping blocks 5 respectively. Multiple slots 6 are provided on the top of the fixed base 1. The slots 6 limit the movement range of the mating parts, ensuring the stability and accuracy of the device during operation. A locking post 7 is rotatably connected to the opposite side of the multiple clamping blocks 5. The device plays an auxiliary positioning and fixing role. The bottom of the outer wall of multiple clamping posts 7 respectively engages with the inner wall of multiple clamping slots 6. The adjacent sides of multiple clamping blocks 5 are respectively fixedly connected to fixing plates 8. Fixing plates 8 increase the contact area with the device to be filmed, improve the stability of clamping, and prevent the device from shaking during film application. Fixing posts 9 are fixedly connected to the top four corners of the fixing base 1. The presence of fixing posts 9 ensures the structural integrity and stability of the entire device. Springs 10 are provided on the outer wall of multiple fixing posts 9. Springs 10 can also restore the relevant parts to the initial position after the film application operation is completed. The bottom of multiple springs 10 are respectively fixedly connected to the top four corners of the fixing base 1. Fixing plates 2 11 are provided on the top of multiple springs 10. Fixing plates 2 11 move up and down under the action of springs 10. Suction cups 12 are fixedly connected to the left and right sides of the inner wall of fixing plates 2 11. A cleaning mechanism 2 is provided on the rear side of the fixing base 1. The cleaning mechanism 2 is used to clean the device to be filmed to remove static electricity and dust.

[0032] Specifically, the operator manually rotates two rotary valves 4, which are connected to the bidirectional threaded rod 3. This causes the bidirectional threaded rod 3 to rotate. Since the clamping block 5 is threaded onto the bidirectional threaded rod 3, the clamping block 5 moves axially as the bidirectional threaded rod 3 rotates, thereby adjusting the spacing of the clamping blocks 5 to match the size of the film application device. As multiple clamping blocks 5 move in adjacent directions, the rear locking post 7 moves within the locking groove 6. After the clamping block 5 is positioned, the locking post 7 engages with the locking groove 6, preventing the bidirectional threaded rod 3 from rotating due to its own malfunction and avoiding errors in the adjusted dimensions. At this point, the film application device is placed on the fixing plate 8. Then, the film is placed on the suction cup 12. After installing the fixing plate 11 and the fixing post 9, the fixing plate 11 is manually pressed down to adhere the film to the device, completing the film application operation. Subsequently, the spring 10 returns, and the device returns to its initial state, ready for the next film application operation.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 2 includes a fixed frame 201. The front side of the fixed frame 201 is fixedly connected to the rear side of the outer wall of the fixed base 1. A rotary valve 202 is provided on the right side of the outer wall of the fixed frame 201. When the operator rotates the rotary valve 202, it can directly drive the right connecting column 203 to rotate, thereby transmitting power to other components of the cleaning mechanism 2 through the connecting column 203, ensuring that the relative position of the cleaning mechanism 2 and the positioning device is fixed in space. The left and right sides of the inner wall of the fixed frame 201 are rotatably connected to the connecting columns 203. The rotatable connection of the connecting columns 203 allows them to rotate freely within the fixed frame 201. When the connecting column 203 rotates, the gear 204 will rotate accordingly. Through the meshing of the gears, the rotational power of the connecting column 203 is transmitted to other gears that mesh with it, realizing the transmission and conversion of power within the cleaning mechanism 2, thereby driving more components to work together. The right end of the outer wall of the right connecting column 203 is fixedly connected to the left side of the outer wall of the rotary valve 202. Gears 204 are fixedly connected to the middle of both connecting columns 203. 204, through meshing with gear 205, drives gear 205 to rotate, further transmitting and distributing power to other parts of the cleaning mechanism 2, promoting the overall movement and operation of the cleaning mechanism 2. Gears 205 are rotatably connected to the left and right sides of the bottom inner wall of the fixed frame 201. The outer walls of the two gears 205 mesh with the outer walls of the two gears 204 respectively. An electrostatic ion fan 206 is provided at the bottom inner wall of the fixed frame 201. The electrostatic ion fan 206 changes the angle and direction of the airflow to expand the cleaning range. To improve the cleaning effect and more comprehensively clean the surface of the film application device, the electrostatic ion fan 206 is fixedly connected to the adjacent ends of two connecting columns 203 on the left and right sides of its outer wall. The front side of the outer wall of the fixing frame 201 is provided with a 207. A scraper 208 is slidably connected to the inner wall of the 207. The scraper 208 is slidably connected to the inner wall of the groove 207. The operator manually pushes the scraper 208 to slide in the groove 207. During the sliding process, the scraper 208 can physically scrape the surface of the film application device.

[0034] Specifically, the front side of the fixing frame 201 of the cleaning mechanism 2 is fixed to the rear side of the outer wall of the fixing base 1, so that the cleaning mechanism 2 and the main body of the positioning device form an integral whole, ensuring that they can work together when the film-applying device is operated. The rotating valve 202 is located on the right side of the outer wall of the fixing frame 201. The right end of the outer wall of the right connecting column 203 is fixedly connected to the left side of the outer wall of the rotating valve 202. When the operator rotates the rotating valve 202, it will drive the connecting column 203 to rotate. Gear 1 204 is fixedly connected to the middle of both connecting columns 203. Gear 2 205 on the left and right sides of the bottom of the inner wall of the fixing frame 201 meshes with the outer walls of the two gear 1 204 respectively. When the connecting column 203 rotates, the first gear 204 rotates accordingly, driving the second gear 205 to rotate through gear meshing, thus realizing the transmission and conversion of power. The outer walls of the electrostatic ion fan 206 are fixedly connected to the adjacent ends of the two connecting columns 203 on the left and right sides respectively. The rotation of the connecting column 203 will drive the electrostatic ion fan 206 to rotate, so that the surface of the film application device is electrostatically eliminated and dust is cleaned from different angles, improving the cleaning effect. A scraper 208 is slidably connected in the groove 207 opened on the front side of the outer wall of the fixing frame 201. The surface of the film application device can be further physically cleaned by sliding the scraper 208 to remove larger dust and impurities.

[0035] Reference Figure 2 , Figure 4 and Figure 5 A fixing block 13 is fixedly connected to the top right side of the outer wall of the fixing frame 201. A button 14 is rotatably connected to the outer wall of the fixing block 13, allowing the operator to easily trigger the associated circuit or mechanical structure by rotating the button 14. A mounting groove 15 is provided on the top front side of the outer wall of the fixing frame 201. A supplementary light 16 is fixedly connected to the inner wall of the mounting groove 15. With the help of the sufficient light provided by the supplementary light 16, the operator can more clearly observe whether there is residual dust and impurities on the surface of the device to be applied. A fixing block 27 is fixedly connected to the rear side of the outer wall of the fixing frame 201. A groove 18 is provided on the top of the fixing block 27. The groove 18 has a storage function. During daily use of the film applicator and maintenance and repair of the cleaning mechanism 2, the maintenance personnel can place commonly used small tools and parts in the groove 18.

[0036] Specifically, the operator triggers the circuit to open and close by turning the button 14, thereby controlling the opening and closing of the electrostatic ion fan 206. The supplementary light 16 provides sufficient light so that the operator can more clearly observe the surface of the device to be covered. During routine maintenance and cleaning of the mechanism 2 or simple repairs to the covering machine, the maintenance personnel place commonly used tools and parts in the groove 18.

[0037] Reference Figure 1 , Figure 2 and Figure 4Support columns 19 are fixedly connected to the four corners of the bottom of the fixed base 1, and foot pads 20 are fixedly connected to the bottom of the support columns 19. By setting support columns 19 at the four corners, the fixed base 1 can be evenly stressed, avoiding tilting or shaking due to uneven stress, and ensuring the stability of the entire positioning device during operation. The top of the fixed base 1 is provided with multiple sliding grooves 21, and sliders 22 are fixedly connected to the front and rear sides of the bottom of multiple clamping blocks 5. The outer walls of multiple sliders 22 are slidably connected to the inner walls of multiple sliding grooves 21. The sliders 22 and sliding grooves 21 are tightly fitted, and the outer walls of sliders 22 can slide smoothly on the inner walls of sliding grooves 21. The top center of the fixed plate 21 is provided with a pressing groove 23. The inner walls of the pressing groove 23 are all rounded. The pressing groove 23 provides a point of force for the operator's hand, allowing the operator to apply force more conveniently and effectively.

[0038] Specifically, the fixed base 1 is stably raised off the ground to avoid direct contact with the ground and wear. When the operator rotates the rotary valve 4 to drive the bidirectional threaded rod 3 to rotate, the clamping block 5 will move under the action of the bidirectional threaded rod 3. At this time, the slider 22 slides in the slide groove 21. The slide groove 21 provides a guiding function for the slider 22, ensuring that the clamping block 5 can move accurately along a specific trajectory, ensuring the accuracy of the clamping block 5's adjustment position, so as to better match the size of the device to be applied. When the operator performs the film application operation, the operator needs to manually press down the fixed plate 11 to make the film adhere to the device. The pressing groove 23 provides the operator with a convenient position to apply force.

[0039] Working principle: The operator manually rotates two rotary valves 4, which drives the bidirectional threaded rod 3 to rotate, causing the clamping block 5 to move along the bidirectional threaded rod 3. The spacing of the clamping block 5 is adjusted to match the size of the device to be applied. When the clamping block 5 moves, the locking post 7 on the rear side moves in the locking groove 6. When the adjustment is completed and the clamping block 5 stops moving, the locking post 7 engages with the locking groove 6 to prevent the bidirectional threaded rod 3 from rotating and causing errors in the adjustment size. The device to be applied is placed on the fixing plate 8, and the film is placed on the suction cups 12 on the left and right sides of the bottom wall of the fixing plate 11. Then the fixing plate 11 and the fixing post 9 are installed. The fixing plate 11 is manually pressed down to make the film adhere to the device to be applied. After the film is applied, the spring 10 returns.

[0040] Furthermore, when using the cleaning mechanism 2, rotating the rotary valve 202 causes the right connecting column 203 to rotate, which in turn drives the right connecting column 203 to rotate. The rotation of the right gear 1 204 then drives the right gear 2 205 to rotate, which in turn causes the left gear 1 204 and the connecting column 203 to rotate via gear transmission. The outer walls of the electrostatic ion fan 206 are fixedly connected to the adjacent ends of the two connecting columns 203 on the left and right sides, respectively. Therefore, the rotation of the connecting column 203 drives the electrostatic ion fan 206 to rotate, adjusting its angle. At the same time, the scraper 208 can slide in the 207 opened on the front side of the outer wall of the fixed frame 201 to scrape and clean the area to be cleaned. After adjusting the angle by rotating the electrostatic ion fan 206, the area to be cleaned can be cleaned by electrostatic ion blowing, achieving overall cleaning.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
