Description

Technical Field

[0001] This utility model belongs to the technical field of electronic product film application equipment, and specifically relates to a positioning device for a film application machine. Background Technology

[0002] Currently, electronic devices are becoming increasingly common. These smart electronic devices typically have screens, which generally have touch functionality. Using the conductive properties of fingers, users touch buttons on the screen to make calls or access menus for information. To prevent scratches caused by frequent touching or external friction, screen protectors are often applied.

[0003] Traditional screen protector applicators primarily use mechanical clamping or vacuum adsorption to initially position the film material (such as protective film, optical film, etc.) and the product to be coated (such as screen, glass panel, etc.). However, existing technologies have the following significant drawbacks:

[0004] 1. Insufficient positioning accuracy: Conventional laminating machines rely on a single-direction positioning reference (such as edge alignment) and lack a multi-degree-of-freedom coordinated adjustment mechanism. During the film peeling process, the accumulation of minute displacements between the film and the product can easily lead to residual air bubbles or film wrinkles during subsequent pushing and venting, especially noticeable on curved or irregularly shaped products.

[0005] 2. Lack of dynamic stability: Existing devices struggle to maintain the pre-set spatial relationship between the film and the product during the transition between the film-tearing and pressing processes. For example, vacuum adsorption positioning is prone to localized detachment due to changes in film tension, while mechanical clamping may cause scratches on the product surface due to rigid contact.

[0006] 3. Limited adaptability: Existing technologies generally employ fixed positioning structures, which cannot be compatible with membrane materials and product combinations of different sizes or thicknesses. Although some equipment has added manual adjustment modules, the adjustment efficiency is low and it is difficult to achieve high-precision repeatable positioning. Utility Model Content

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] like Figures 5 to 7As shown, the film applicator positioning device is a device that adheres the protective film on the film applicator material 300 to the screen of an electronic product. The existing film applicator material 300 is typically composed of multiple layers, mainly including a first release film 301, a protective film 302, and a second release film 303. The protective film 302 is the protective structure that actually needs to be adhered to the screen of the electronic product. The first release film 301 covers the first side of the protective film 302, providing basic scratch, dust, and fingerprint protection. The second release film 303 covers the second side of the protective film 302 (i.e., the adhesive layer for bonding the protective film 302 to the screen), protecting the adhesive layer during the application process and preventing contamination. To adapt to the film applicator positioning device provided in this embodiment, the first release film 301 has four positioning holes 304 arranged in a front-back, left-right, and right-backwards configuration.

[0038] Please refer to the following: Figures 1 to 7 The positioning device for the film applicator provided in the embodiments of this utility model will now be described.

[0039] like Figures 1 to 7 As shown, the positioning device of the film applicator in this embodiment of the present invention includes a body 100 and a positioning mechanism 200. The top plate of the body 100 is provided with a placement area 101 for placing the product to be applicated and a positioning block 102 disposed outside the placement area 101 for positioning the film material 300. The positioning block 102 matches the positioning hole 304 preset on the first release film 301 of the film material 300. The positioning mechanism 200 is disposed on the body 100 and can position and fix the product to be applicated on the placement area 101 so that the center line of the product to be applicated coincides with the center line of the film material 300.

[0040] In this embodiment, the positioning mechanism 200 includes a centering component and a pushing component; the centering component includes a centering clamp 201 and a first driving component 202. Two centering clamps 201 are provided and symmetrically arranged on the left and right sides of the placement area 101. The first driving component 202 is disposed within the body 100, and its output end is connected to the two centering clamps 201 respectively, enabling the two centering clamps 201 to move towards each other or away from each other. The pushing component includes a pushing clamp 203 and a first driving component 202. The second drive assembly 204 is located inside the body 100. The output end of the second drive assembly 204 is connected to the push chuck 203 and can drive the push chuck 203 to move back and forth along the length of the body 100. A limiting stop 103 is provided at the front end of the placement area 101. The push chuck 203 can push the product to be applied close to the limiting stop 103, thereby realizing the front and rear positioning and clamping of the product to be applied.

[0041] In actual operation, when positioning and fixing the product to be coated and the coating material 300, firstly, press the control button 108 to enter the release program of the positioning mechanism 200. The first drive component 202 and the second drive component 204 work to release the centering clamp 201 and the pushing clamp 203 until the centering clamp 201 and the pushing clamp 203 return to their initial positions. Then, place the product to be coated in the placement area 101. Next, press the control button 108 again to enter the clamping program of the positioning device. First, the first drive component 202 drives the centering clamp 201 to center and position the product to be coated. The centerline of the product to be coated is aligned with the centerline of the machine body 100. Then, the second drive assembly 204 drives the pusher chuck 203 to push the product to be coated to the preset position (i.e., the limiting stop 103), and the centering chuck 201 and the pusher chuck 203 are kept in a clamped state. Finally, the product is matched and positioned by the positioning hole 304 preset on the first release film 301 of the coating material 300 and the positioning post set on the outside of the placement area 101. At this time, the centerline of the product to be coated is aligned with the centerline of the coating material 300, and the positioning and fixing operation of the product to be coated and the coating material 300 is completed.

[0042] Therefore, the film applicator positioning device according to the present utility model uses the positioning block 102 and the positioning mechanism 200 to accurately position the film applicator material 300 and the product to be applicated, respectively, so as to ensure that the film applicator material 300 and the product to be applicated maintain a preset spatial relationship during the subsequent film peeling and pushing air release process, thereby improving the film applicator accuracy.

[0043] It can also be understood that, through the synergistic action of the left and right centering clamps 201 and the pushing clamps 203, this embodiment of the invention can quickly and accurately position the product to be coated in the center of the placement area 101, ensuring accurate placement of the product during coating application. Secondly, the pushing clamps 203 push the product to the limiting stop 103, achieving stable clamping and preventing the product from moving during the coating process, thus ensuring coating quality. Furthermore, the user only needs to place the product to be coated in the placement area 101, and the device automatically completes the centering and clamping operations without manual adjustment, greatly improving coating efficiency. Finally, this positioning mechanism 200 is suitable for products of various sizes; by adjusting the positions of the centering clamps 201 and the pushing clamps 203, it can accommodate products of different sizes to be coated.

[0044] For example, the front side of the body 100 is provided with a boss 104, which protrudes upward from the top plate of the body 100 and forms the limiting stop 103 at the front end of the placement area 101.

[0045] For example, the protrusion 104 has a positioning concave surface 111 on the side near the placement area 101 for supporting the front end of the first release film 301; the rear side of the body 100 has two protruding pillars 105 arranged symmetrically from left to right, the protruding pillars 105 protruding upward from the top plate of the body 100 and for supporting the rear end of the first release film 301; the upper end surface of the protruding pillars 105 is higher than the positioning concave surface 111, so that the film material 300 gradually tilts upward from front to back. Thus, the positioning concave surface 111 and the protruding pillars 105 can support the film material 300 to be suspended directly above the product to be filmed, ensuring that a certain amount of tearing space is reserved between the film material 300 and the product to be filmed; at the same time, the film material tilting upward from front to back can better cooperate with the tearing and air venting operation from front to back. If the film material is parallel to the screen of the product to be filmed, the downward pushing and air venting force during film application will cause the film material to release air prematurely, affecting the film application quality. Furthermore, to ensure that the film material 300 can be accurately positioned in the center of the placement area 101, four positioning blocks 102 are provided, two of which are fixedly fixed to the positioning concave surface 111 in a symmetrical manner, and the other two are fixedly fixed to the upper end face of the protruding post 105.

[0046] For example, in order to enable the centering clamp 201 and the pushing clamp 203 to be positioned within the placement area 101, the left and right sides of the placement area 101 are respectively provided with first openings 106 that allow the centering clamp 201 to move within them, and the upper part of the centering clamp 201 protrudes upward from the first opening 106 to facilitate clamping the product to be applied; the rear side of the placement area 101 is provided with a second opening 107 that allows the pushing clamp 203 to move within it, and the upper part of the pushing clamp 203 protrudes upward from the second opening 107 to facilitate pushing the product to be applied.

[0047] For example, the first drive assembly 202 includes a first mounting plate 205, a first guide bar 206, a first rack 207, a first gear 208, and a first motor 209. The first mounting plate 205 is fixed to the bottom of the top plate of the body 100. A first interlayer is formed between the first mounting plate 205 and the top plate of the body 100 for arranging the first guide bar 206, the first rack 207, and the first gear 208. The first guide bar 206 and the first rack 207 are parallel to each other and extend along the width direction of the body 100. The first guide bar 206 and the first rack 207 are respectively fixedly connected to the bottom of the centering chuck 201. The first mounting plate 205 is provided with two parallel first guide ribs 210. The first guide bar 206 and the first rack 207 are respectively provided with first sliding grooves 211 that slide with the first guide ribs 210. The teeth of the first rack 207 connected to the left centering chuck 201 are opposite to the teeth of the first rack 207 connected to the right centering chuck 201. The first gear 208 is disposed between the two first racks 207 and its front and rear sides are respectively meshed with the two first racks 207. The first motor 209 is fixed inside the machine body 100, and the output shaft of the first motor 209 is fixedly connected to the first gear 208. Therefore, the first drive assembly 202, through the meshing transmission of the first gear 208 and the first rack 207, can precisely control the moving distance of the centering clamp 201, ensuring that the product to be applied is accurately centered in the left-right direction of the placement area 101. Furthermore, the sliding cooperation of the first guide strip 206 and the first guide rib 210 ensures that the centering clamp 201 moves smoothly and reliably during movement, avoiding wobbling and improving positioning accuracy. In addition, all components of the first drive assembly 202, except for the first motor 209, are installed within the first interlayer, resulting in high space utilization and a compact overall structure.

[0048] For example, the second drive assembly 204 includes a second mounting plate 212, a second guide bar 213, a second rack 214, a second gear 215, and a second motor 216. The second mounting plate 212 is fixed to the bottom of the top plate of the body 100 and is located below the first mounting plate 205. A second interlayer is formed between the second mounting plate 212 and the top plate of the body 100, and between the second mounting plate 212 and the first mounting plate 205, for arranging the second guide bar 213, the second rack 214, and the second gear 215. The second guide bar 213 and the second rack 214 are parallel to each other and extend along the length direction of the body 100. The second guide bar 213 and the second rack 214 are respectively fixedly connected to the bottom of the push chuck 203; the second mounting plate 212 is provided with two parallel second guide ribs 217, and the second guide bar 213 and the second rack 214 are respectively provided with second sliding grooves 218 that slide with the second guide ribs 217; the teeth of the second rack 214 are opposite to the second guide bar 213, and the second gear 215 is disposed between the second rack 214 and the second guide bar 213 and one side of the gear 215 meshes with the second rack 214; the second motor 216 is fixed inside the machine body 100, and the output shaft of the second motor 216 is fixedly connected to the second gear 215. Therefore, the second drive assembly 204, through the meshing transmission of the second gear 215 and the second rack 214, can precisely control the forward and backward movement distance of the push chuck 203, ensuring accurate positioning of the product to be applied in the forward and backward direction of the placement area 101. Furthermore, the sliding engagement of the second guide bar 213 and the second guide rib 217 ensures that the push chuck 203 moves smoothly and reliably during movement, avoiding wobbling and improving positioning accuracy. In addition, all components of the second drive assembly 204, except for the second motor 216, are installed within the second interlayer, resulting in high space utilization and a compact overall structure.

[0049] For example, both the first motor 209 and the second motor 216 are mounted on the bottom surface of the second mounting plate 212, which is compact and easy to assemble.

[0050] For example, the placement area 101 is provided with a recess 109 for the protruding part on the back of the product to be covered to enter, so as to better adapt to the shape of the product to be covered, so that the screen of the product to be covered remains horizontal when the film is applied, ensuring the stability and accuracy of the film application process.

[0051] For example, the limiting stop 103, the centering clamp 201 and the pushing clamp 203 are all provided with buffer pads 110 to avoid scratches on the product surface caused by rigid contact during mechanical clamping.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
