Description

Technical Field

[0001] The present invention belongs to the technical field of electronic product film laminating equipment, and in particular relates to an automatic film laminating machine and a film laminating method thereof. Background Art

[0002] Electronic devices are becoming increasingly popular. These smart devices often have touchscreens. Using the conductive properties of your fingers, you can make calls or access menus by touching buttons on the screen. To prevent scratches from frequent contact or external friction, a screen protector is often applied.

[0003] Existing film-applying methods all rely on manual positioning and pasting, which places high operational requirements on the film-applying personnel, has low work efficiency, and is difficult to guarantee the film-applying effect. The film is often scrapped due to improper film application, bubbles, or impurities. Manual film application requires first cleaning the screen, then tearing off the release layer and aligning the film with the screen, and finally covering the screen for adhesion. During this series of operation processes, dust in the air can easily adhere to the screen or the film, resulting in poor film application effect. Manual film application requires gradually covering the film on the screen along the axial direction, which is complicated and requires high technical requirements.

[0004] In response to the defects of manual film application, various "film application artifacts" have appeared on the market. Users can use the "film application artifacts" to apply the film by themselves. The "film application artifact" is actually a protective film with an attached film application tool. Users can use the film application tool to complete the film application themselves, but the film application effect of the existing "film application artifacts" is still poor. The release film needs to be completely torn off before the protective film can be attached to the screen. The sticky layer of the protective film is exposed for a long time and is easy to adhere to dust. In addition, the pressing and exhaust operations still need to be performed manually, with a low degree of automation. Manual operation is difficult to ensure the uniformity and consistency of pressing, which easily leads to the generation of bubbles, and the quality and efficiency of film application are low.

[0027] The automatic film laminating machine provided by the present invention has the following beneficial effects compared with the prior art:

[0028] The automatic film laminating machine of the embodiment of the present invention uses the positioning block and the positioning device to accurately position the film laminating material and the product to be laminating respectively, so as to ensure that the film laminating material and the product to be laminating always maintain a preset spatial relationship during the subsequent film tearing and pushing and exhausting process, thereby improving the film laminating accuracy; at the same time, through the coordinated work of the film tearing device and the pushing and exhausting device, the operation of pushing while separating the release film (i.e., the second release film) can be realized, so that the contact surface between the protective film and the screen is gradually expanded, and the air is naturally discharged from front to back, avoiding being "trapped" under the film to form bubbles; and the adhesive surface of the protective film is only exposed at the moment of peeling off the release film, reducing the chance of dust adhesion, and the continuous action of synchronous pushing further compresses the time window for dust to enter; it can be seen that the automatic film laminating machine of the embodiment of the present invention realizes the automation of film laminating operation, has high film laminating accuracy, can prevent the generation of bubbles and the entry of dust to a great extent, reduces the need for rework of film tearing and re-pasting, saves time and reduces the scrap rate of the protective film.

[0029] In addition, the present invention also provides a film laminating method using the automatic film laminating machine described above, which includes the following steps:

[0030] Step 1: Position and fix the product to be filmed:

[0031] First, press the first control button to enter the loosening procedure of the positioning device, and loosen the centering chuck and the ejecting chuck until they return to their initial positions;

[0032] Then place the product to be filmed in the placement area;

[0033] Then press the first control button to enter the clamping program of the positioning device, first drive the centering chuck to center the product to be laminated, then drive the ejecting chuck to push the product to be laminated to the preset position, and keep the centering chuck and the ejecting chuck in a clamped state;

[0034] Step 2: Position and fix the film material:

[0035] First, the positioning holes preset on the first release film of the film material are matched with the positioning blocks provided outside the placement area to make the center line of the film material coincide with the center line of the product to be filmed;

[0036] Then the second release film of the film material is connected to the film tearing device;

[0037] Step 3: Tear off, push and exhaust the film material:

[0038] Press the second control button to enter the film tearing and laminating program, start the film tearing device, and gradually separate the second release film of the laminating material from the protective film of the laminating material from the front to the back. The separated second release film is rolled up and temporarily stored or directly sent out of the equipment. After the film tearing device rotates a set number of times, the pushing and exhausting device is started. The pushing rubber roller on the pushing and exhausting device synchronously pushes the separated protective film from the front to the back to adhere it to the product to be laminating, and expel the air under the protective film surface.

[0039] The stroke control of the push exhaust device is achieved by any of the following modes:

[0040] In the first mode, the travel of the push-exhaust device is controlled by the front travel switch and the rear travel switch; when the push-exhaust device touches the rear travel switch, the push-exhaust device performs a return stroke; when the push-exhaust device touches the front travel switch, the push-exhaust device stops;

[0041] In the second mode, the travel of the push-exhaust device is controlled by the rear travel switch and the system return program. After the push-exhaust device starts from the initial position, when the push-exhaust device touches the rear travel switch, the push-exhaust device performs a return stroke and returns to the initial position according to the travel set by the system return program.

[0042] In the third mode, the travel of the push-exhaust device is controlled by the system return program. When the push-exhaust device is started at the initial position, it can reach the final position from the initial position and return to the initial position from the final position according to the travel set by the system return program.

[0043] Step 4: Tear off the first release film and remove the second release film to complete the film application process.

[0044] The present invention provides an automatic film laminating machine with a film laminating method. Compared with the prior art, the present invention has the following beneficial effects:

[0045] The film pasting method of the automatic film pasting machine in the embodiment of the present invention has the advantages of simple operation, high film pasting precision, high efficiency and good quality. The user only needs to place the product to be pasted in the placement area and press the first control button. The product to be pasted can be centered and clamped through the clamping program of the positioning device, ensuring that the film can accurately fit the screen of the product to be pasted without edge deviation; then, press the second control button to automatically run the film tearing and film pasting program, realizing the operation of separating the release film while pushing, automatically exhausting air during the film pasting process, ensuring that the film surface is flat and no bubbles are generated, and at the same time, the film pasting can be completed in a short time, which compresses the time window for dust entry, greatly reduces the chance of dust adhesion, and improves the quality and efficiency of film pasting.

Therefore, they cannot be understood as limitations on the present invention.

[0071] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0072] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0073] like Figures 11 to 14As shown, the automatic film laminating machine is a device that adheres the protective film on the film material 700 to the screen of the electronic product; the existing film material 700 is usually composed of multiple layers of materials, mainly including a first release film 701, a protective film 702 and a second release film 703, wherein the protective film 702 is a protective structure that actually needs to be adhered to the screen of the electronic product, the first release film 701 is covered on the first side of the protective film 702, and provides the protective film 702 with basic anti-scratch, dust-proof and anti-fingerprint protection; the second release film 703 is covered on the second side of the protective film 702 (that is, the sticky layer that the protective film 702 is bonded to the screen), which protects the sticky layer of the film during the film laminating process and prevents the sticky layer from being contaminated. In order to adapt to the use of the automatic film laminating machine provided in an embodiment of the present invention, positioning holes 704 are preset on the first release film 701, and there are 4 positioning holes 704 in total and arranged in the front, back, left and right directions. Pulling holes 705 are preset on the second release film 703, and there are 2 traction holes 705 in total, and they are arranged at the tearing force position of the second release film 703.

[0074] Please also refer to Figures 1 to 10 Now, the automatic film laminating machine provided by the embodiment of the present invention is described.

[0075] like Figures 1 to 10 As shown, the automatic film laminating machine of the embodiment of the present invention includes a machine body 100, a positioning device 200, a film tearing device 300 and a pushing and exhausting device 400. The top plate of the machine body 100 is provided with a placement area 101 for placing the product to be film-laminated and a positioning block 102 arranged on the outside of the placement area 101 and used for positioning the film laminating material 700. The positioning block 102 matches the positioning hole 704 preset on the first release film 701 of the film laminating material 700; the positioning device 200 is arranged on the machine body 100, and can position and fix the product to be film-laminated on the placement area 101, so that the product to be film-laminated can be fixed. The center line of the film product coincides with the center line of the film material 700; the film tearing device 300 is arranged at the rear end of the body 100, and can pull the second release film 703 of the film material 700 and the protective film 702 of the film material 700 to gradually separate from the front to the back; the pushing and exhausting device 400 can be arranged on the body 100 so as to be movable forward and backward, and can synchronously push the separated protective film 702 from the front to the back during the separation process of the second release film 703 of the film material 700 and the protective film 702 of the film material 700 to adhere to the product to be filmed, and expel the air under the surface of the protective film 702.

[0076] According to the embodiment of the present invention, the automatic film laminating machine accurately positions the film material 700 and the product to be laminating through the positioning block 102 and the positioning device 200 respectively, so as to ensure that the film material 700 and the product to be laminating always maintain a preset spatial relationship during the subsequent film tearing and pushing and exhausting process, thereby improving the film laminating accuracy; at the same time, through the coordinated work of the film tearing device 300 and the pushing and exhausting device 400, the operation of pushing while separating the release film (i.e., the second release film 703) can be realized, so that the contact area between the protective film 702 and the screen is gradually expanded, and the air is naturally discharged from the front to the back, avoiding being "trapped" under the film to form bubbles; and the adhesive surface of the protective film 702 is only exposed at the moment of peeling off the release film, reducing the chance of dust adhesion, and the continuous action of synchronous pushing further compresses the time window for dust to enter; it can be seen that the automatic film laminating machine of the embodiment of the present invention realizes the automation of film laminating operation, has high film laminating accuracy, can prevent the generation of bubbles and the entry of dust to a great extent, reduces the need for rework of film tearing and re-laminating, saves time and reduces the scrap rate of the protective film 702.

[0077] For example, Figures 2 to 5 As shown, the positioning device 200 includes a centering component and a pushing component; the centering component includes a centering chuck 201 and a first driving component 202, the centering chuck 201 is provided with two and is symmetrically arranged on the left and right sides of the placement area 101, for clamping the two sides of the product to be film-coated; the first driving component 202 is arranged in the body 100, and the output end of the first driving component 202 is respectively connected to the two centering chucks 201 and can drive the two centering chucks 201 to move toward or away from each other to realize the film-coated product. The film product is aligned left and right to ensure that the center line of the product to be filmed is aligned with the center line of the film material 700; the pushing assembly is provided with a pushing chuck 203 and a second drive assembly 204. The pushing chuck 203 is arranged at the rear side of the placement area 101 and is used to push the product to be filmed from the rear; the second drive assembly 204 is arranged in the body 100, and the output end of the second drive assembly 204 is connected to the pushing chuck 203 and can drive the pushing chuck 203 to move forward and backward along the length direction of the body 100. In this embodiment, the front side of the body 100 is provided with a boss 103, which protrudes upward from the placement area 101 and forms a limiting rib 104 at the front end of the placement area 101. The pushing chuck 203 can push the product to be filmed against the limiting rib 104, thereby achieving front and rear positioning and clamping of the product to be filmed.

[0078] Furthermore, the boss 103 is provided with a positioning concave surface 112 on one side near the placement area 101 for supporting the front end of the first release film 701. The rear side of the housing 100 is provided with two symmetrically arranged protrusions 113, which protrude upward from the top plate of the housing 100 and support the rear end of the first release film 701. The upper end surfaces of the protrusions 113 are higher than the positioning concave surface 112, causing the film material 700 to gradually tilt upward from the front to the back. Thus, the positioning concave surface 112 and the protrusions 113 support the film material to be suspended directly above the product to be applied, ensuring a certain amount of film tearing space between the film material and the product to be applied. Furthermore, the film material tilting upward from the front to the back better cooperates with the film tearing and exhaust operation from the front to the back. If the film material is parallel to the screen of the product to be applied, the downward pressure and exhaust force provided by the exhaust device 400 during film application will cause the film material to be exhausted prematurely, affecting the quality of the application.

[0079] To ensure that the film material 700 can be accurately positioned at the center of the placement area 101, four positioning blocks 102 are provided, two of which are fixed on the positioning concave surface 112 in a left-right symmetrical manner, and the other two positioning blocks 102 are respectively fixed on the upper end surfaces of the convex columns 113.

[0080] Furthermore, if Figure 1 As shown, in order to enable the centering chuck 201 and the ejecting chuck 203 to be able to adjust their positions within the placement area 101, the left and right sides of the placement area 101 are respectively provided with first openings 105 allowing the centering chuck 201 to move therein, and the upper part of the centering chuck 201 protrudes upward from the first opening 105 to facilitate clamping the product to be film-applied; the rear side of the placement area 101 is provided with a second opening 106 allowing the ejecting chuck 203 to move therein, and the upper part of the ejecting chuck 203 protrudes upward from the second opening 106 to facilitate pushing the product to be film-applied.

[0081] It can be understood that the embodiment of the present invention, through the coordinated action of the left and right centering chucks 201 and the ejecting chuck 203, can quickly and precisely position the product to be filmed in the center of the placement area 101, ensuring that the product is accurately placed during film application. Secondly, the ejecting chuck 203 pushes the product to the limiting rib 104, achieving stable clamping, preventing the product to be filmed from moving during the film application process and ensuring the quality of the film application. Furthermore, the user only needs to place the product to be filmed in the placement area 101, and the equipment automatically completes the centering and clamping operations, eliminating the need for manual adjustment, greatly improving film application efficiency. Finally, this positioning device 200 is suitable for products of various sizes. By adjusting the positions of the centering chuck 201 and the ejecting chuck 203, it can accommodate products of different sizes to be filmed.

[0082] In this embodiment, Figures 3 to 5 As shown, the first driving 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.

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 fixedly connected to the bottom of the centering chuck 201 respectively. The first mounting plate 205 is provided with two first guide ribs 210 parallel to each other, and the first guide bar 206 and the first rack 207 are respectively provided with first sliding grooves 211 that slide with the first guide rib 210; the tooth portion of the first rack 207 connected to the left centering chuck 201 is opposite to the tooth portion of the first rack 207 connected to the right centering chuck 201, and the first gear 208 is arranged between the two first racks 207 and its front and rear sides are respectively engaged with the two first racks 207; the first motor 209 is fixed in the body 100, and the output shaft of the first motor 209 is fixedly connected to the first gear 208. Thus, the first drive assembly 202, through the meshing transmission of the first gear 208 and the first rack 207, can precisely control the movement distance of the centering chuck 201, ensuring that the product to be film-applied is accurately centered in the left-right direction of the placement area 101. Furthermore, the sliding cooperation between the first guide bar 206 and the first guide rib 210 ensures that the centering chuck 201 moves smoothly and reliably, preventing shaking and improving positioning accuracy. Furthermore, all components of the first drive assembly 202, except for the first motor 209, are mounted within the first interlayer, achieving high space utilization and a compact overall structure.

[0083] In this embodiment, Figures 3 to 5As shown, the second driving 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 the second mounting plate 212 is located below the first mounting plate 205. A second interlayer for arranging the second guide bar 213, the second rack 214 and the second gear 215 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. 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 ejection chuck 203; two second guide ribs 217 parallel to each other are provided on the second mounting plate 212, 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 arranged between the second rack 214 and the second guide bar 213 and one side of it is engaged with the second rack 214; the second motor 216 is fixed in the body 100, and the output shaft of the second motor 216 is fixedly connected to the second gear 215. Thus, 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 of the ejection chuck 203, ensuring precise positioning of the product to be film-applied in the front-to-back direction within the placement area 101. Furthermore, the sliding cooperation between the second guide bar 213 and the second guide rib 217 ensures smooth and reliable movement of the ejection chuck 203, preventing shaking and improving positioning accuracy. Furthermore, all components of the second drive assembly 204, except for the second motor 216, are mounted within the second interlayer, resulting in high space utilization and a compact overall structure.

[0084] For example, Figure 2 and Figure 6As shown, the film tearing device 300 includes a traction roller 301 and a third drive assembly 302, the traction roller 301 is arranged along the width direction of the body 100, and the two ends of the traction roller 301 are rotatably connected to the side walls of the body 100 respectively; a winding wheel 303 is fixed on the traction roller 301, and the winding wheel 303 is provided with a one-way hanging tooth 304 that can connect with the traction hole 705 preset on the second release film 703 of the film material 700, and the one-way hanging tooth 304 is provided with two and is arranged 180 degrees apart along the circumferential direction of the winding wheel 303, so that one of the one-way hanging teeth 304 can smoothly hook the second release film 703 under forward rotation, and can detach from the second release film 703 under reverse rotation; the third drive assembly 302 is arranged in the body 100, and the output end of the third drive assembly 302 is connected to the traction roller 301 and can drive the traction roller 301 to rotate forward or reverse. When the third drive assembly 302 drives the traction roller 301 to rotate forward, the reel 303 can wind up the second release film 703, thereby tearing the second release film 703 off the film material 700. If the rolled-up second release film 703 needs to be released, the third drive assembly 302 can drive the traction roller 301 to rotate in the reverse direction. Thus, under the control of the third drive assembly 302, the traction roller 301 of the film tearing device 300 can automatically rotate forward or reverse, achieving automatic tearing and releasing of the release film without manual operation, greatly improving film application efficiency. The one-way hanging teeth 304 cooperate with the traction holes 705 on the second release film 703 to ensure that the release film can be accurately hooked and smoothly torn off. In addition, the automated film tearing process reduces human error and avoids damage or unevenness of the film material 700 caused by manual film tearing, thereby improving the overall quality of the film application.

[0085] Furthermore, if Figure 6 As shown, the third driving assembly 302 includes a driving gear 305, a driven gear 306, and a third motor 307. The third motor 307 is fixed to the machine body 100. The output shaft of the third motor 307 is fixedly connected to the driving gear 305. The driven gear 306 is fixedly connected to the traction roller 301 and meshes with the driving gear 305. Therefore, when the second release film 703 needs to be wound up, the third motor 307 rotates forward, driving the traction roller 301 to rotate forward, winding the second release film 703 around the traction roller 301. When the second release film 703 needs to be released, the third motor 307 rotates reversely, driving the traction roller 301 to rotate in the opposite direction, releasing the second release film 703 from the traction roller 301.

[0086] Furthermore, if Figure 1 and Figure 2As shown, the rear end of the machine body 100 is provided with a receiving chamber 107 capable of accommodating the traction roller 301 and the wound second release film 703, thereby providing a dedicated space for storing and protecting the wound second release film, making the overall layout of the film laminating machine more neat and tidy, and preventing the release film from being scattered and piled outside the machine body 100. In addition, the outer side of the receiving chamber 107 is provided with an inlet and outlet for the second release film to enter and exit the receiving chamber.

[0087] Furthermore, if Figure 6 As shown, the film tearing device 300 also includes a clamping assembly 308, which is arranged below the traction roller 301 and can compress the second release film 703 being rolled up to ensure the stability and reliability of the release film during the rolling process. In specific implementation, the clamping assembly 308 includes a clamping wheel 309, a fixed seat 310, a lifting seat 311 and a compression spring 312. The fixed seat 310 is provided with a mounting cavity 313. The fixed seat 310 is fixed to the bottom of the receiving chamber 107 and the upper end of the mounting cavity 313 is connected to the receiving chamber 107; the lifting seat 311 is arranged in the mounting cavity 313 and can be moved up and down; the compression spring 312 is fixed in the mounting cavity 313 and its upper end is against the bottom of the lifting seat 311; the clamping wheel 309 is rotatably connected to the lifting seat 311 and can be pushed into the receiving chamber 107 under the elastic force of the compression spring 312. Therefore, when the traction roller 301 starts to reel in the second release film 703, the pressure wheel 309 can be pushed into the receiving chamber 107 under the elastic force of the compression spring 312, and tightly press the reeled release film to prevent loosening or slipping during the reeling process, thereby ensuring the neatness and stability of the reeling; secondly, the rotation design of the pressure wheel 309 reduces the friction between the release film and the release film, ensuring that the release film can be reeled in smoothly; furthermore, through the elastic adjustment of the compression spring 312, the clamping assembly 308 can adapt to release films of different thicknesses and has strong versatility.

[0088] Furthermore, if Figure 6 As shown, the pressing assembly 308 is located below the middle of the pulling roller 301, and two winding wheels 303 are provided and symmetrically arranged on the left and right sides of the pressing assembly 308. This symmetrical layout ensures that the second release film 703 is evenly stressed during pulling and winding, avoiding deflection caused by unilateral pulling and improving the stability of film tearing and winding.

[0089] In other optional embodiments, such as Figure 7As shown, the film tearing device can also use a mechanical biting method to achieve the dual functions of stable traction and separation and synchronous delivery of the second release film, specifically: the film tearing device includes a traction roller 301, a biting roller 314 and a third driving component 302, and the traction roller 301 and the biting roller 314 are both arranged along the width direction of the machine body; the two ends of the traction roller 301 are respectively rotatably connected to the two side walls of the machine body, and the traction roller 301 is fixed with a plurality of first biting wheels 315 arranged at equal intervals; the two ends of the biting roller 314 are respectively rotatably connected to the two side walls of the machine body 100, and the biting roller 314 is fixed with a plurality of second biting wheels 316 arranged at equal intervals; the first biting wheel 315 and the second biting wheel 316 are staggered with each other, and the first biting wheel 315 A plurality of radially raised engaging portions 317 are provided on the outer periphery, and the engaging portions 317 are designed like gear teeth to provide gripping force for the film; the engaging portions 317 extend into the interval space formed by two adjacent second engaging wheels 316 to ensure that the film is alternately clamped and released when passing through to prevent slipping; the third driving component 302 is arranged in the body 100, and the output end of the third driving component 302 is connected to the traction roller 301 and can drive the traction roller 301 to rotate in the forward direction; the rear end of the body 100 is provided with a receiving chamber 107 that can accommodate the traction roller 301 and the engaging roller 314, and the outer side of the receiving chamber 107 is provided with a feed port for the second release film 703 to enter the interior of the receiving chamber 107 and a discharge port for the second release film 703 to be sent from the inside of the receiving chamber to the outside of the equipment. The third drive assembly 302 includes a driving gear 305, a driven gear 306, and a third motor 307. The third motor 307 is fixed to the machine body 100. The output shaft of the third motor 307 is fixedly connected to the driving gear 305. The driven gear 306 is fixedly connected to the traction roller 301 and meshes with the driving gear 305. Therefore, when the third motor 307 rotates forward, it drives the traction roller 301 to rotate forward. The engaging portion 317 periodically inserts into the gap of the engaging roller 314, forming a "gear-tooth-slot" fit. This design continuously clamps the second release film 703 during rotation, and pulls the separated second release film 703 from the feed port into the receiving chamber. At the same time, through intermittent release, the separated second release film 703 is continuously delivered to the outside of the device from the discharge port.

[0090] For example, Figure 2 、 Figure 8 and Figure 9As shown, the pushing exhaust device 400 includes a gantry bracket 401, a pushing rubber roller 402 and a fourth drive assembly 403. The gantry bracket 401 is provided with a crossbeam 404 and two columns 405 respectively connected to the two ends of the crossbeam 404. The crossbeam 404 is suspended above the body 100 to play a supporting role. The two columns 405 are respectively slidably connected to the side walls of the body 100 on both sides, allowing the crossbeam 404 and the pushing rubber roller 402 to move forward and backward along the length direction of the body 100; the pushing rubber roller 402 is arranged along the width direction of the body 100, and the pushing rubber roller 402 is arranged along the width direction of the body 100. The hinge support 406 is rotatably connected to the bottom of the beam 404 to ensure that the pushing rubber roller 402 can evenly press the protective film 702 onto the surface of the product with the film; the fourth driving component 403 is arranged in the body 100, and the output end of the fourth driving component 403 is connected to the column 405 and can drive the column 405 to move back and forth along the length direction of the body 100, thereby driving the pushing rubber roller 402 to push on the surface of the product, evenly pressing the protective film 702 onto the surface of the product, and at the same time expelling the air between the protective film 702 and the product to avoid the generation of bubbles.

[0091] Furthermore, if Figure 9 As shown, a UV lamp 407 is provided at the bottom of the crossbeam 404, and the UV lamp 407 is distributed on both sides of the pushing rubber roller 402. Thus, the irradiation of the UV lamp 407 can effectively kill microorganisms on the film surface and the screen surface, ensuring the cleanliness and hygiene of the film application process.

[0092] In this embodiment, Figure 9As shown, the fourth drive assembly 403 includes a connecting plate 408, a slider 409, a guide rail 410, a screw nut pair 411 and a fourth motor 412. The guide rail 410 is fixed in the body 100 and is arranged along the length direction of the body 100; the slider 409 is slidingly connected to the guide rail 410; the fourth motor 412 is fixed in the body 100, and the output shaft of the fourth motor 412 is fixedly connected through the screw of the screw nut pair 411, and the nut of the screw nut pair 411 is fixedly connected to the slider 409; the connecting plate 408 is fixedly connected to the nut of the screw nut pair 411, and the two ends of the connecting plate 408 extend from the two side walls of the body 100 respectively and are fixedly connected to the columns 405 on both sides. After the fourth motor 412 is started, the rotation of its output shaft is converted into linear motion of the slider 409 and the connecting plate 408 through the screw nut pair 411. Under the guidance of the slider 409 and the guide rail 410, the linear driving force of the screw nut pair 411 is transmitted to the gantry bracket 401 through the connecting plate 408. The movement of the gantry bracket 401 drives the push rubber roller 402 to move back and forth along the length of the body 100, completing the pushing operation. Thus, the fourth drive assembly 403 can achieve precise movement of the push rubber roller 402 through the precise transmission of the fourth motor 412 and the screw nut pair 411, ensuring the uniformity and consistency of the film application process. The sliding cooperation between the guide rail 410 and the slider 409 ensures the smoothness and linearity of the movement process, avoids shaking or deviation, and improves the quality of the film application. In addition, all components of the fourth drive assembly 403 are installed in the body 100, which has high space utilization and a compact overall structure that does not take up too much space.

[0093] Furthermore, if Figure 8 As shown, the front and rear ends of the guide rail 410 are respectively provided with a front travel switch 413 and a rear travel switch 414 for controlling the front and rear limit positions of the gantry bracket 401. The front and rear travel switches 413 and 414 are respectively electrically connected to the fourth motor 412. The connecting plate 408 is fixed with switch contacts 415 that can contact or sense the front and rear travel switches 413 and 414. In this embodiment, the front and rear travel switches 413 and 414 can be contact travel switches or non-contact travel switches. Thus, the provision of the front and rear travel switches 413 and 414 enables automated control of the fourth motor 412, eliminating the need for manual intervention in the movement of the push rubber roller 402, thereby improving film application efficiency and consistency.

[0094] Furthermore, if Figure 1As shown, the side walls of the body 100 are provided with guide grooves 108 extending along the length of the body 100, and the pillars 405 are provided with guide protrusions 416 that slidably engage with the guide grooves 108. Thus, the design of the guide grooves 108 and the guide protrusions 416 enables the pillars 405 to maintain precise guidance and stability during movement, further improving the reliability of the device and the quality of film application.

[0095] For example, Figure 1 As shown, the front end of the body 100 is provided with a first control button 109 for controlling the operation of the positioning device 200 and a second control button 110 for controlling the operation of the film tearing device 300 and the pushing and exhausting device 400, so as to facilitate the user to control the working status of the device. The number of buttons is small and the appearance of the device is simple.

[0096] For example, Figure 1 As shown, the placement area 101 is provided with a recessed position 111 for the raised portion on the back of the product to be filmed to be placed, so that it can better adapt to the shape of the product to be filmed, so that the screen of the product to be filmed can always remain horizontal during filming, ensuring the stability and accuracy of the filming process.

[0097] For example, Figure 10 As shown, the automatic film laminating machine also includes a protective shell 500 and a protective cover 600. The protective shell 500 is arranged around the body 100 and is fixedly connected to the body 100 to provide physical protection for the body 100 and its internal components of the film laminating machine to prevent external dust, debris or accidental collisions from causing damage to the equipment; the protective cover 600 is covered on the protective shell 500, so that the film laminating operation on the body 100 is in the space enclosed by the protective cover 600 and the protective shell 500, thereby ensuring that the film laminating process is carried out in a relatively closed and clean environment, reducing the impact of the external environment on the film laminating operation, such as airflow, humidity, dust, etc.; at the same time, it prevents the operator from accidentally contacting the moving parts of the equipment, reducing operational risks.

[0098] In addition, the present invention also provides a film laminating method using the automatic film laminating machine described above, which includes the following steps:

[0099] Step 1: Position and fix the product to be filmed:

[0100] First, the first control button 109 is pressed to enter the release procedure of the positioning device 200. The first motor 209 and the second motor 216 work to release the centering chuck 201 and the ejecting chuck 203 until the centering chuck 201 and the ejecting chuck 203 return to their initial positions.

[0101] Then place the product to be film-coated in the placement area 101;

[0102] Then, the first control button 109 is pressed to enter the clamping process of the positioning device 200. First, the first motor 209 drives the centering chuck 201 to center and position the product to be laminated. Then, the second motor 216 drives the ejecting chuck 203 to push the product to be laminated to a preset position (i.e., the limiting rib 104). The centering chuck 201 and the ejecting chuck 203 are kept in a clamped state.

[0103] Step 2: Position and fix the film material 700:

[0104] First, the positioning holes 704 preset on the first release film 701 of the film material 700 are matched with the positioning blocks 102 provided outside the placement area 101 for positioning;

[0105] Then, the second release film 703 of the film material 700 is connected to the film tearing device. In this embodiment, the second release film 703 of the film material 700 is connected to the winding wheel 303 of the film tearing device 300 through the traction hole 705 preset on the second release film 703 of the film material 700. In other optional embodiments, the second release film 703 of the film material 700 is clamped by the traction roller 301 and the nip roller 314 on the film tearing device 300.

[0106] Step 3: Tear off, push and exhaust the film material 700:

[0107] Pressing the second control button 110 enters the film tearing and laminating program, starts the film tearing device 300, and the third motor 307 operates. The second release film 703 of the laminating material 700 and the protective film 702 of the laminating material 700 are pulled by the traction roller 301 to gradually separate from the front to the back, and the separated second release film 703 is rolled up and temporarily stored. After the film tearing device 300 (i.e., the third motor 307) rotates a set number of times, the pushing and exhausting device 400 is started, and the fourth motor 412 operates, driving the pushing rubber roller 402 on the gantry bracket 401 to move synchronously from the front to the back, pushing the separated protective film 702 to adhere to the product to be laminating, and at the same time, removing the air under the laminating surface of the protective film 702.

[0108] The stroke control of the push exhaust device 400 is achieved by any one of the following modes:

[0109] In the first mode, the travel of the push-exhaust device is controlled by the front travel switch and the rear travel switch. When the push-exhaust device 400 (specifically, the switch contact 415 fixed on the connecting plate 408) touches the rear travel switch 414, the push-exhaust device 400 performs a return stroke (i.e., the fourth motor 412 starts the reverse mode). When the push-exhaust device 400 (specifically, the switch contact 415 fixed on the connecting plate 408) touches the front travel switch 413, the push-exhaust device 400 (i.e., the fourth motor 412) stops.

[0110] In the second mode, the travel of the push-exhaust device 400 is controlled by the rear travel switch and the system return program. After the push-exhaust device 400 is started from the initial position, when the push-exhaust device 400 touches the rear travel switch 414, the push-exhaust device performs a return stroke and returns to the initial position according to the travel set by the system return program.

[0111] In the third mode, the travel of the push-exhaust device 400 is controlled by the system return program. When the push-exhaust device 400 is started at the initial position, it can continuously move from the initial position to the final position and then return from the final position to the initial position according to the travel set by the system return program.

[0112] Step 4: tear off the first release film 701 and remove the second release film 703 to complete the film lamination operation.

[0113] It is understandable that after the film application operation is completed, the first control button 109 is pressed to re-enter the release process of the positioning device 200. After the user takes out the film-applied product, a new product to be applied can be placed to enter the next working cycle.

[0114] In summary, the film pasting method of the automatic film pasting machine in the embodiment of the present invention has the advantages of simple operation, high film pasting precision, high efficiency and good quality. The user only needs to place the product to be pasted in the placement area 101 and press the first control button 109. The product to be pasted can be centered and clamped through the clamping program of the positioning device 200, ensuring that the film can accurately fit the screen of the product to be pasted without edge deviation; then, press the second control button 110 to automatically run the film tearing and film pasting program, and realize the operation of pushing while separating the release film. Air is automatically discharged during the film pasting process to ensure that the film surface is flat and no bubbles are generated. At the same time, the film pasting can be completed in a short time, which compresses the time window for dust entry, greatly reduces the chance of dust adhesion, and improves the quality and efficiency of film pasting.

[0115] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
