Description

Technical Field

[0001] This utility model relates to the field of film application technology, and in particular to a protective film application device for small lens parts. Background Technology

[0002] Cameras are found in many everyday electronic products such as mobile phones, smartwatches, and laptops to capture images. These camera modules have complex structures, typically assembled from many high-precision small parts. During the manufacturing process of these small lens components, a protective film is often applied to their surfaces to prevent scratches and protect them. Currently, the application of protective films to small lens components in the industry mostly involves manual alignment of the parts and the protective film. The pre-cut film is aligned and directly applied to the surface of the small lens component, then pressed or smoothed by hand to ensure adhesion. However, due to the skill level of the operators, misalignment of the protective film during application is common, resulting in poor adhesion. Secondly, manually smoothing the film can easily create air bubbles at the adhesion point, further affecting the quality of the application. Furthermore, this method, which involves manually applying film to each component individually, is inefficient and increases production costs. Utility Model Content

[0014] In one embodiment, a first rolling bearing is provided at the part where the rubber roller is rotatably connected to the fixed block, and a second rolling bearing is provided at the part where the connecting plate is rotatably connected to the mounting base.

[0015] In one embodiment, the upper surface of the product base is provided with a plurality of cylindrical support platforms, and the sides of the cylindrical support platforms are provided with locking blocks. The cylindrical support platforms and the locking blocks together form the product placement position. The product to be coated is placed on the cylindrical support platforms, and the product to be coated has a locking slot that engages with the locking blocks.

[0016] In one embodiment, both the product base and the cover plate are rectangular plate structures, and at least two opposite sides of the product base are provided with pick-up and put-down notches, which penetrate the upper surface of the product base.

[0026] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] Please combine Figure 1-2 as well as Figure 5-6 This utility model discloses a protective film applying device 10 for small lens parts with high applying quality and efficiency. This device is used to attach protective films 20 to the surface of small lens parts. The protective film 20 includes a guide film material 201 and several product films 202 disposed on the surface of the guide film material 201. The guide film material 201 loads and moves several product films 202 onto the product 30 to be coated, so that the product films 202 are adhered to the product surface under the rolling action of a rubber roller, thereby achieving batch coating of products. The product 30 to be coated includes a circular sheet-like part 301 to be coated and a mounting ring 302 fixed below the part 301. The mounting ring 302 provides a connection point for assembling the small lens parts with the other components of the lens module.

[0028] Specifically, in this embodiment, the protective film applicator includes a base plate 100, a product base 200, a cover plate 300, and a rolling assembly 400. The base plate 100 has a clamp mounting area in the center of its upper surface. The product base 200 is located within the clamp mounting area and is fixedly connected to the base plate 100. The upper surface of the product base 200 has several product placement positions for receiving the product 30 to be applicated. The cover plate 300 covers and is fixed to the product base 200. The upper surface of the cover plate 300 is flat and has an applicator area for receiving the protective film 20. The cover plate 300 has several through holes 310 corresponding to each product placement position. The product 30 to be applicated is located within the through holes 310 and placed on the product placement position, with the upper surface of the product 30 flush with or higher than the upper surface of the cover plate 300. In this embodiment, the thickness of the cover plate 300 needs to satisfy the following condition: after the product 30 to be coated is placed in the product placement position, the upper surface of the product 30 to be coated is flush with or protrudes from the upper surface of the cover plate 300, so that the protective film 20 can adhere to the upper surface of the product under the rolling pressure of the adhesive roller, ensuring the normal progress of the product coating operation. Furthermore, by opening a through hole 310 in the cover plate 300, when the product is placed in the product placement position, the product is simultaneously located within the through hole 310. Thus, through the combined constraint of the product placement position and the inner wall of the through hole 310, the product can be limited, ensuring that the relative position of the protective film 20 and the product in the horizontal direction remains unchanged during the coating operation, thereby improving the coating quality. The rolling assembly 400 includes a guide bracket 410, a mounting frame 420 slidably mounted on the guide bracket 410 and suspended above the cover plate 300 and movable along the length or width of the base plate 100 under external force, a roller bracket 430 rotatably connected to the mounting frame 420 and rotatable in a vertical plane to approach or move away from the product base 200, and a roller 440 rotatably mounted on the roller bracket 430 and rolling the protective film 20 to make the protective film 20 adhere to the product. Preferably, the roller 440 is made of silicone material. By rotatably connecting the roller bracket 430 to the mounting frame 420, the roller 440 can rotate and abut against the protective film 20, pressing the protective film 20 against the product surface, or rotate and lift away from the protective film 20 to remove the product. By rotating the rubber roller 440 on the rubber roller bracket 430, the protective film 20 is smoothed out by the rotation of the rubber roller 440 when applying the protective film 20, and then smoothly applied to the small lens parts, avoiding the generation of air bubbles.

[0029] Please combine further Figure 1-2 as well as Figure 5-11In the film application process, firstly, the rubber roller 440 and the rubber roller bracket 430 are moved so that they rotate relative to the mounting frame 420 and move away from above the product base 200 to clamp the product. Then, several products 30 to be filmed are placed on the product placement positions of the product base 200, and the cover plate 300 is placed on and fixed to the product base 200. The cover plate 300 and the product base 200 together position the product. After the product is positioned, the protective film 20 to be applied is placed over the film application area of ​​the cover plate 300 and fixed. Then, the rubber roller bracket 430 is rotated in the opposite direction, causing the rubber roller 440 to rotate above the product base 200 until the rubber roller 440 and the protective film 20 are in contact. Pulling the roller 440 and roller bracket 430 causes the mounting bracket 420 to move the roller bracket 430 and roller 440 on the guide bracket 410, so that the roller 440, while rolling and pressing the protective film 20, contacts each part of the protective film 20 in turn, so as to press all the product film 202 on the guide film 201 onto the corresponding product surface. After the film is applied, pull the mounting bracket 420, roller bracket 430 and roller 440 back to the initial position, and lift the roller bracket 430 and roller 440 to remove the protective film 20, which is now only the guide film 201. Then, remove the cover plate 300 from the product base 200 to remove the film-applied product.

[0030] The product base 200 is used to support the film-applied product 30 and, together with the cover plate 300, positions the product. In one embodiment, the upper surface of the product base 200 is provided with a plurality of cylindrical support platforms 210, which are arranged in an array on the upper surface of the product base 200. The sides of the cylindrical support platforms 210 are provided with locking blocks 220. The cylindrical support platforms 210 and the locking blocks 220 together form a product placement position. The film-applied product 30 is placed on the cylindrical support platform 210, and the film-applied product 30 has a locking slot that engages with the locking block 220. Preferably, the mounting ring 302 of the product has a locking slot. Thus, through the mutual constraint between the locking slot on the product and the locking block 220 on the cylindrical support platform 210, the product can be limited to prevent rotation on the cylindrical support platform 210. In actual operation, when different sizes and models of products need to be produced, only the product base 200 needs to be replaced, making the operation convenient and quick.

[0031] Furthermore, in this embodiment, both the product base 200 and the cover plate 300 are rectangular plate structures. At least two opposite sides of the product base 200 have retrieval notches 230 that penetrate the upper surface of the product base 200. Preferably, the length of the cover plate 300 is the same as the length of the product base 200, and the width of the cover plate 300 is the same as the width of the product base 200, so that by aligning the edges of the cover plate 300 with the product base 200, the through holes 310 on the cover plate 300 are aligned with the cylindrical support platforms 210 on the product base 200. In this embodiment, by providing retrieval notches 230 on the sides of the product base 200, it is easier for operators to grasp the edges of the cover plate 300 and remove it from the product base 200, thus reducing the difficulty of removing the cover plate 300. Preferably, each of the four sides of the product base 200 has a retrieval notch 230.

[0032] In one embodiment, the product base 200 is connected to the base plate 100 by screws or magnetic attraction. For example, the product base 200 is screwed to the base plate 100 by inserting a screw through the lower surface of the base plate 100; or at least one first magnet is fixed to the lower surface of the product base 200 and at least one second magnet is fixed to the upper surface of the base plate 100, and the magnetic attraction between the first and second magnets is achieved. To achieve a fixed connection between the product base 200 and the cover plate 300, in one embodiment, the product base 200 and the cover plate 300 are magnetically connected, i.e., magnets are respectively provided on the edges of the product base 200 and the cover plate 300, and the cover plate 300 is fixed to the product base 200 by the magnetic attraction between the magnets. In another embodiment, the upper surface of the product base 200 is provided with a plurality of pins 240, and the cover plate 300 is provided with a plurality of through holes 320 for correspondingly inserting each pin 240. In this way, by passing the pins 240 on the product base 200 through the corresponding through holes 320 on the cover plate 300, the relative displacement of the cover plate 300 and the product base 200 in the horizontal direction can be restricted by the mutual constraint between the pins 240 and the inner wall of the through holes 320, thereby fixing the cover plate 300. Furthermore, the guide film material 201 of the protective film 20 is also provided with connection holes 203 corresponding to each pin 240. When the protective film applicator is assembled, the pins 240 are passed through the through holes 320 and the connection holes 203 in sequence, so as to fix the cover plate 300 on the surface of the product base 200 and position the protective film 20 on the surface of the cover plate 300, so as to prevent the protective film 20 from moving relative to the product under the drive of the rubber roller 440 during the applicator process, thereby improving the applicator quality.

[0033] The guide bracket 410 supports the mounting frame 420 and defines its sliding path. In one embodiment, the guide bracket 410 includes a column fixed to the upper surface of the base plate 100 and located beside the product base 200, and a cantilever fixed to the top of the column and located above the product base 200. The cantilever extends along the length or width of the base plate 100. The mounting frame 420 is slidably mounted on the cantilever and, under the action of an external force, drives the roller bracket 430 and the roller 440 to move along the length of the cantilever. In another embodiment, the guide bracket 410 includes two guide rods 411 oppositely disposed on both sides of the fixture mounting area and fixedly connected to the base plate 100, two guide blocks 412 slidably mounted on the two guide rods 411, and two connecting blocks 413 fixedly on the upper surfaces of the two guide blocks 412. The mounting frame 420 includes two mounting bases 421 fixedly on the two connecting blocks 413, and the roller bracket 430 is rotatably connected to the mounting bases 421. In this embodiment, the two connecting blocks 413 are integrally formed, and / or the two mounting bases 421 are integrally formed. The mounting bases 421 are fixed to the connecting blocks 413 by screws, and the connecting blocks 413 are fixed to the guide blocks 412 by screws. Preferably, the two connecting blocks 413 are integrally formed, which improves the overall structural stability of the guide bracket 410. In addition, a linear bearing 414 is provided at the sliding engagement part between the guide block 412 and the guide rod 411, making the back-and-forth movement of the guide block 412 on the guide rod 411 smoother and more fluid, improving the stability of the rubber roller 440 when moving in the horizontal direction, and also reducing the wear of the guide block 412 when sliding on the guide rod 411, thus extending the service life of the protective film applicator. Preferably, a first hole is provided on the guide block 412, and a linear bearing 414 is provided in the first hole. The guide rod 411 passes through the first hole and slides in engagement with the linear bearing 414.

[0034] In one embodiment, the upper surface of the base plate 100 has a pair of lugs on each of the two opposite sides of the fixture mounting area. A guide rod 411 is fixedly connected between each pair of lugs, and the lugs are screwed to the base plate 100. In another embodiment, the upper surface of the base plate 100 has a mounting notch 110 on each of the two opposite sides of the fixture mounting area. Two positioning blocks 415 fixedly connected to the base plate 100 are arranged opposite each other in each mounting notch 110. Each guide rod 411 is located in a mounting notch 110 and is fixedly connected to the two positioning blocks 415 in the mounting notch 110. Preferably, the positioning blocks 415 are screwed to the base plate 100.

[0035] Please combine Figure 1-5In one embodiment, the roller support 430 includes two fixing blocks 431 disposed opposite to both ends of the roller 440 and pivotally connected to the roller 440. The rolling assembly 400 also includes a connecting plate 450, one side of which is rotatably connected to two mounting bases 421, and the other side of which is fixedly connected to the two fixing blocks 431. A gripper 460 is provided on the upper surface of the connecting plate 450. The gripper 460 is used to provide a gripping part for the operator to pull the roller support 430 and the mounting frame 420 horizontally, thereby reducing the difficulty of operation. In this embodiment, a first rotating hole is provided on the inner side of the fixing block 431 (the side of one fixing block 431 adjacent to another fixing block 431). A first cylindrical protrusion is provided at each end of the rubber roller 440. The two first cylindrical protrusions are rotatably inserted into the first rotating holes of the two fixing blocks 431. Thus, during the horizontal movement of the rubber roller 440 and its contact with the protective film 20, the rubber roller 440 will rotate relative to the fixing block 431 under the frictional force of the protective film 20. A second rotating hole is provided on the inner side of the mounting base 421 (the side of one mounting base 421 adjacent to another mounting base 421). Two second cylindrical protrusions are provided on the connecting plate 450 and are rotatably inserted into the second rotating holes of the two mounting bases 421. Thus, when the connecting plate 450 is subjected to a tangential traction force or tangential component force perpendicular to the upper surface of the connecting plate 450, the connecting plate 450 will drive the fixing block 431 and the rubber roller 440 to rotate relative to the mounting base 421. Furthermore, in this embodiment, a first rolling bearing 432 is provided at the rotatable connection between the rubber roller 440 and the fixing block 431, and a second rolling bearing 422 is provided at the rotatable connection between the connecting plate 450 and the mounting base 421. Preferably, a first rolling bearing 432 is provided in each first rotating hole, and a first cylindrical protrusion is inserted into the first rotating hole and cooperates with the first rolling bearing 432; a second rolling bearing 422 is provided in each second rotating hole, and a second cylindrical protrusion is inserted into the second rotating hole and cooperates with the second rolling bearing 422. By providing the first rolling bearing 432, the rotation of the rubber roller 440 can be made smoother and more stable, and the wear of the first cylindrical protrusion at the end of the rubber roller 440 and the fixing block 431 can be reduced. Similarly, by providing the second rolling bearing 422, the frictional force of the connecting plate 450 rotating relative to the mounting base 421 can be reduced, and the difficulty of the rubber roller bracket 430 driving the rubber roller 440 to rotate in the vertical plane can be reduced.

[0036] The protective film applicator 10 for small lens parts of this invention, through the cooperation of the product base 200 and the cover plate 300, can clamp multiple products at once. By pulling the mounting bracket 420 and the rubber roller bracket 430 to slide on the guide bracket 410, the rubber roller 440 is pressed onto the protective film 20 on the cover plate 300. While the rubber roller 440 moves horizontally relative to the protective film 20 on the cover plate 300, it also rolls relative to the protective film 20, thereby pressing the protective film 20 onto the product. This achieves the application of film to multiple products at once, improving the film application efficiency and reducing the product production cost. The product base 200 and the cover plate 300 jointly position the product, which can prevent the product from shifting during the film application process, ensuring that the product and the protective film 20 are aligned and bonded, thus improving the film application yield. The rolling application method of the rubber roller 440 replaces the smoothing by pressing with fingers, reducing the air bubbles generated during the film application process and improving the film application quality.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
