Description

Technical Field

[0001] The present invention relates to the technical field of anti-peeping films. More specifically, the present invention relates to a high light transmittance anti-peeping film for electronic products and its processing and laminating device. Background Art

[0002] In modern life, as the functionality of electronic communication devices becomes more and more powerful, there is also more and more information storage in electronic communication devices, and the protection of information has attracted more and more attention. The emergence of anti-peeping films can effectively protect business secrets and personal privacy, and can help users avoid commercial losses caused by the leakage of screen information when using a computer, and privacy is importantly protected.

[0003] When producing an anti-peeping film, a processed glass sheet is laminated with an anti-peeping AB adhesive layer through a composite processing method. The anti-peeping AB adhesive layer is formed by an anti-peeping layer plus two-sided adhesive layers. One side is used to bond the glass, and the other side is used to bond the screen. When laminating the glass sheet with the anti-peeping AB adhesive film, a laminating machine is generally used. During production, first, the staff places the glass sheet on a moving platform and tears off the film on its surface; then, the laminating device sucks the anti-peeping AB adhesive film transmitted and pastes it on the glass sheet, that is, the processing is completed.

[0004] The anti-peeping AB adhesive film is conveyed piece by piece on a protective film. The laminating device needs to use a vacuum adsorption mechanism to suck the anti-peeping AB adhesive film and then laminate it. In order to ensure that the anti-peeping AB adhesive film and the glass sheet can be correctly aligned, positioning is required before the vacuum adsorption mechanism sucks. The current method is to set two positioning blocks. The two positioning blocks first hold the two ends of the anti-peeping AB adhesive film to prevent the anti-peeping AB adhesive film from falling, and then move closer to and contact the anti-peeping AB adhesive film at the same time to achieve the positioning purpose.

[0005] When the positioning blocks hold and position the anti-peeping AB adhesive film, the positioning blocks contact the bottom of the anti-peeping AB adhesive film. And the anti-peeping AB adhesive film has an adhesive layer. During positioning, relative movement occurs between the adhesive layer and the positioning blocks, causing friction, which easily causes wrinkles in the adhesive layer, resulting in texture defects after the anti-peeping AB adhesive film is laminated with the glass sheet. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to the attached drawings of the specification Figures 1 - 13 A processing and laminating device for a high light transmittance privacy film for electronic products includes a workbench 1. A bracket 3 is installed on the workbench 1, and a bearing platform 2 is installed on the bracket 3. The bearing platform 2 is used to bear the glass sheet 101.

[0038] In the above technical solution, as Figure 11 shown, the bearing platform 2 includes a first linear drive component 21 installed on the bracket 3. The output end of the first linear drive component 21 is fixedly connected with a bearing plate 22. The bearing plate 22 is used to bear the glass sheet 101. A first limiting strip 221 and a second limiting strip 222 are respectively arranged on one side and the rear end of the upper surface of the bearing plate 22. The thicknesses of the first limiting strip 221 and the second limiting strip 222 are smaller than the thickness of the glass sheet 101. A suction hole 223 is opened on the upper surface of the bearing plate 22. The suction hole 223 is connected to a vacuum generator, so that the suction hole 223 can adsorb the glass sheet 101.

[0039] It should be noted that the linear drive component 21 adopts a lead screw slide device to drive the carrier plate 22 to move. During use, the glass sheet 101 is placed on the carrier plate 22, with one side of the glass sheet 101 aligned with the first limiting strip 221 and one end aligned with the second limiting strip 222 to achieve the purpose of positioning. The glass sheet 101 is adsorbed and fixed through the suction holes 223 to prevent the position of the glass sheet 101 from shifting when the carrier plate 22 moves.

[0040] In this embodiment, a fitting component 5 is provided above the carrier table 2, and a conveying component 4 is provided on one side of the fitting component 5. The conveying component 4 is used to convey the anti-peeping AB glue film 110 to the fitting component 5, and the fitting component 5 is used to clamp the anti-peeping AB glue film 110 and paste the anti-peeping AB glue film 110 on the glass sheet 101.

[0041] In the above technical solution, the conveying component 4 includes a mounting plate 41 fixedly installed on the workbench 1. A plurality of horizontally arranged conveying rollers 42 are rotatably connected to the mounting plate 41. A flat plate 43 is provided on one side of the conveying roller 42 closest to the fitting component 5. A winding roller 44 is rotatably connected to the lower side position of the mounting plate 41. A first rotary drive component 45 is installed on the rear side of the mounting plate 41. The first rotary drive component 45 is used to drive the winding roller 44 to rotate. The protective film 200 carrying the anti-peeping AB glue film 110 sequentially passes through the upper surfaces of a plurality of conveying rollers 42, the flat plate 43, the lower side of the flat plate 43 and is wound around the winding roller 44.

[0042] It should be noted that the protective film 200 is conveyed from the previous station to the conveying component 4. As Figure 10 shown, three conveying rollers 42 are provided. The protective film 200 first passes through the three conveying rollers 42, then passes through the surface of the flat plate 43, and finally passes through the lower side of the flat plate 43 and is wound around the winding roller 44. The first rotary drive component 45 is a reduction motor, which is used to drive the winding roller 44 to rotate to wind the protective film 200. When the protective film 200 is transmitted downward from the front end of the flat plate 43, the protective film 200 bends. Since the anti-peeping AB glue film 110 pasted on the protective film 200 has relatively poor softness compared to the protective film 200, it will not bend downward but will be peeled off from the protective film 200. The above state is the state of the leftmost anti-peeping AB glue film 110 as Figure 9 shown. In this state, since a part of the anti-peeping AB glue film 110 is peeled off, the fitting component 5 can be used to clamp the anti-peeping AB glue film 110.

[0043] Furthermore, as Figures 1 - 3 and Figures 9 - 10As shown, a positioning roller 46 is disposed above one of the conveying rollers 42, and the anti-peeping AB adhesive film 110 is carried and passes between the conveying roller 42 and the positioning roller 46.

[0044] It should be noted that during the conveyance of the protective film 200, the positioning roller 46 presses on the surface of the protective film 200, which can improve the conveyance stability of the protective film 200.

[0045] In the above technical solution, the laminating assembly 5 includes a second linear driving member 50. The output end of the second linear driving member 50 is fixedly installed with a mounting frame 51. A third linear driving member 52 is installed on the mounting frame 51. The output end below the third linear driving member 52 is fixedly connected with a movable plate 53. The bottom of the movable plate 53 has a downward convex portion 531. An adsorption hole is formed at the bottom of the downward convex portion 531. The adsorption hole is connected to a vacuum generator, so that the adsorption hole can adsorb the anti-peeping AB adhesive film 110.

[0046] It should be noted that the second linear driving member 50 adopts a screw nut device, which is used to drive the mounting frame 51 to move horizontally. The third linear driving member 52 uses a cylinder to drive the movable plate 53 to move vertically. The adsorption hole is used to adsorb the anti-peeping AB adhesive film 110. Of course, adsorption should be carried out after the anti-peeping AB adhesive film 110 is positioned.

[0047] Furthermore, as Figure 7 shown, linear driving members four 54 are fixedly installed on both sides of the mounting frame 51. The output ends of the two linear driving members four 54 are fixedly installed with clamping plates 55. One side of the bottom of the clamping plate 55 close to the middle of the mounting frame 51 has a vertical surface 551. The lower side of the vertical surface 551 has an inclined surface 552. When the two clamping plates 55 clamp the anti-peeping AB adhesive film 110 to make the anti-peeping AB adhesive film 110 bend upward, the end of the anti-peeping AB adhesive film 110 is located at the position where the vertical surface 551 and the inclined surface 552 meet.

[0048] It should be noted that the linear driving member four 54 adopts a cylinder. The two clamping plates 55 are respectively driven by the two linear driving members four 54 to clamp the anti-peeping AB adhesive film 110, so as to complete the positioning of the two ends of the anti-peeping AB adhesive film 110.

[0049] Furthermore, as Figure 5 and Figure 7 shown, a back plate 56 is fixedly connected to the side of the mounting frame 51 away from the conveying assembly 4. A second rotary driving member 59 is installed on the side of the mounting frame 51 close to the conveying assembly 4. The output end of the second rotary driving member 59 is fixedly connected with a pushing plate 591. The second rotary driving member 59 is used to drive the pushing plate 591 to swing, so as to make the pushing plate 591 push the side of the anti-peeping AB adhesive film 110.

[0050] It should be noted that the second rotation driving component 59 uses a reduction motor. The second rotation driving component 59 drives the push plate 591 to swing, pushing the side of the anti-peeping AB adhesive film 110, so that the other side of the anti-peeping AB adhesive film 110 contacts the back plate 56, completing the positioning of the two sides of the anti-peeping AB adhesive film 110.

[0051] In this embodiment, the implementation method is specifically as follows: when the glass sheet 101 and the anti-peeping AB adhesive film 110 are compounded and laminated:

[0052] First, place the glass sheet 101 on the carrier plate 22, align one side edge of the glass sheet 101 with the first limiting strip 221, and one end with the second limiting strip 222 to achieve the purpose of positioning. Then tear off the film on the glass sheet 101, and then adsorb and fix the glass sheet 101 through the suction holes 223. Drive the carrier plate 22 to move through the first linear driving component 21, so that the glass sheet 101 is located directly below the laminating assembly 5.

[0053] Second, the protective film 200 is conveyed from the previous station to the conveying assembly 4, and successively passes from above the three conveying rollers 42, the upper surface of the flat plate 43, and below the flat plate 43 and is wound around the winding roller 44. As Figure 9 shown, when the anti-peeping AB adhesive film 110 is conveyed to the front end of the flat plate 43, the anti-peeping AB adhesive film 110 is peeled off from the protective film 200. After a part is peeled off, the laminating assembly 5 is used for clamping.

[0054] Third, when the laminating assembly 5 clamps the protective film 200, first the second linear driving component 50 drives the mounting frame 51 to move towards the conveying assembly 4, so that the two clamping plates 55 are respectively located at both ends of the anti-peeping AB adhesive film 110. Then the two fourth linear driving components 54 respectively drive the two clamping plates 55 to approach each other, clamp at both ends of the anti-peeping AB adhesive film 110, and make the middle part of the anti-peeping AB adhesive film 110 bend upward. The end of the anti-peeping AB adhesive film 110 is located at the position where the vertical surface 551 and the inclined surface 552 meet, completing the positioning of both ends of the anti-peeping AB adhesive film 110. As Figure 8 shown, since the inclined surface 552 slopes downward and the anti-peeping AB adhesive film 110 bends upward, the adhesive layer at the bottom of the anti-peeping AB adhesive film 110 does not contact the inclined surface 552.

[0055] Fourthly, the rotary driving component II 59 drives the push plate 591 to swing downward, pushing the side surface of the anti-peeping AB glue film 110 to move the anti-peeping AB glue film 110, so that the other side surface of the anti-peeping AB glue film 110 contacts the back plate 56, thus completing the positioning of the two side surfaces of the anti-peeping AB glue film 110. In this process, in order to ensure the stability of the anti-peeping AB glue film 110, before pushing the anti-peeping AB glue film 110, the movable plate 53 can also be moved downward so that the lower convex part 531 contacts the middle part of the anti-peeping AB glue film 110, but the adsorption holes do not adsorb.

[0056] Fifthly, the linear driving component III 52 drives the movable plate 53 to make the lower convex part 531 contact the middle part of the anti-peeping AB glue film 110, and the adsorption holes adsorb the middle part of the anti-peeping AB glue film 110. Then the two linear driving components IV 54 drive the two clamping plates 55 to move away from each other respectively, releasing the clamping of the anti-peeping AB glue film 110. During this process, the two ends of the anti-peeping AB glue film 110 recover upward elastically. During this process, the glue layer at the bottom of the anti-peeping AB glue film 110 does not contact the inclined surface 552 either.

[0057] Sixthly, the linear driving component III 52 drives the movable plate 53 to move downward to make the anti-peeping AB glue film 110 adhere to the glass sheet 101 to form the anti-peeping film 100. After the fitting is completed, the linear driving component I 21 drives the carrier plate 22 to move back, and the staff can take out the fitted anti-peeping film 100.

[0058] Through the above technical solution, by setting two clamping plates 55 and arranging a vertical surface 551 and an inclined surface 552 at the bottom of the two clamping plates 55, when clamping the anti-peeping AB glue film 110, the anti-peeping AB glue film 110 is bent upward. In this way, during the clamping and positioning, the glue layer at the bottom of the anti-peeping AB glue film 110 does not contact the clamping plate 55, and thus there will be no relative movement and friction, ensuring that after the anti-peeping AB glue film 110 is fitted to the glass sheet 101, there will be no defects such as wrinkle patterns in the glue layer.

[0059] Refer to the attached Figure 5 and Figure 7 , on both sides of the lower surface of the movable plate 53, connection blocks 57 are fixedly connected. Adsorption tubes 58 are fixedly installed on the two connection blocks 57. The bottom of the adsorption tube 58 is flush with the bottom of the lower convex part 531. The side wall at the bottom of the adsorption tube 58 has a side opening 581, and the side opening 581 is of an inverted U-shaped structure. The adsorption tube 58 is communicated with a suction fan.

[0060] It should be noted that when the two clamping plates 55 cancel the clamping of the anti-peeping AB glue film 110, and when the lower convex part 531 drives the anti-peeping AB glue film 110 to move downward so that the side of the anti-peeping AB glue film 110 disengages from the back plate 56, the two ends of the anti-peeping AB glue film 110 will vibrate. To reduce the vibration and enable the anti-peeping AB glue film 110 to be quickly and accurately attached to the glass sheet 101. When the two clamping plates 55 cancel the clamping of the anti-peeping AB glue film 110, the exhaust fan sucks air, creating negative pressure at the bottom of the adsorption tube 58. When the anti-peeping AB glue film 110 contacts the bottom of the adsorption tube 58, the amplitude of the end of the anti-peeping AB glue film 110 can be reduced, thereby greatly reducing the vibration. When the anti-peeping AB glue film 110 contacts the bottom of the adsorption tube 58, air can enter the adsorption tube 58 from the side opening 581.

[0061] Refer to the attached drawings of the specification Figures 1 - 3 、 Figures 9 - 10 On one side of the upper surface of the flat plate 43 close to the fitting assembly 5, there is a protruding part 431. Above the flat plate 43, there is a pressing component 47. The pressing component 47 includes a connecting plate 471 fixed to the mounting plate 41. On both sides of the bottom of the connecting plate 471, there are pressing rods 472 fixedly installed. At the bottom of the pressing rods 472, there are rolling balls 473. The protruding part 431 is used to upwardly support the middle part of the anti-peeping AB glue film 110, and the rolling balls 473 are used to downwardly press the two ends of the anti-peeping AB glue film 110, so as to make the anti-peeping AB glue film 110 bend upward.

[0062] It should be noted that since some force is required when the two clamping plates 55 clamp the anti-peeping AB glue film 110, in order to prevent the anti-peeping AB glue film 110 from bending downward and causing the anti-peeping AB glue film 110 to contact the bottom of the inclined surface 552 during clamping, before clamping, it is necessary to make the anti-peeping AB glue film 110 bend upward in advance. Specifically, as Figure 9 and Figure 10 shown, during the process of conveying the protective film 200 to the left, when the protective film 200 passes through the pressing component 47, the two ends of the anti-peeping AB glue film 110 are subjected to the downward pressure of the rolling balls 473, and the protruding part 431 upwardly supports the middle part of the anti-peeping AB glue film 110. Therefore, the anti-peeping AB glue film 110 to be clamped can be made to bend upward. Then, the two clamping plates 55 can directly clamp the two ends of the anti-peeping AB glue film 110 without the problem of the anti-peeping AB glue film 110 contacting the bottom of the inclined surface 552.

[0063] Refer to the attached drawings of the specification Figures 1 - 3 、 Figure 11 On both sides of the bracket 3, there are support plates 6 installed. Between the two support plates 6, there is a pressure roller 61 rotatably connected. The pressure roller 61 is located above the bearing plate 22.

[0064] It should be noted that after the glass sheet 101 and the anti-peeping AB adhesive film 110 are bonded together, when the carrying plate 22 moves back, the pressing roller 61 can press the anti-peeping AB adhesive film 110 downwards, so that the glass sheet 101 and the anti-peeping AB adhesive film 110 are bonded together tightly.

[0065] Refer to the instruction manual Figure 1 , Figure 12 and Figure 13 A material unloading component 300 is provided on one side of the bracket 3, and the material unloading component 300 includes a material box 301.
