[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] Note: The adhesive-backed strip noise reduction component (also known as a sound-absorbing sponge) described in this invention can be any one of polyurethane sponge, foam cotton, or pearl cotton, and the sound-absorbing sponge can be pre-formed into a strip-shaped cuboid with a certain thickness according to actual needs (as shown in the attached figure). Figure 11A (As shown) or prefabricated into a structure with a certain thickness, the main body being a strip-shaped cuboid but with beveled ends (as shown in the attached figure). Figure 11B As shown in the attached document. Figure 11A and 11BAs shown, the adhesive-backed strip noise reduction component 50 may include a sponge body 51, an adhesive layer 52 disposed on one side of the sponge body 51, and a release paper 53 covering the adhesive layer 52. The release paper is also called silicone paper or anti-stick paper. The release paper may also be other sheet-like materials that also isolate and protect the adhesive layer 52 (this application only uses release paper as an example). The ends of the adhesive-backed strip noise reduction component 50 of the present invention are a head end 50A and a tail end 50B.

[0047] As attached Figures 1 to 12 As shown, this invention discloses a release paper separation device 1 for an adhesive-backed strip noise reduction component 50, which includes a mounting plate 10, and a fixing element 20, a separation assembly 30, a cutting assembly 40, and an air blowing assembly 60 disposed on the mounting plate 10; wherein, the fixing element 20 is used to fix the end of the strip noise reduction component 50 (as shown in the attached diagram). Figure 11A End 50B as shown or as attached Figure 11B (As shown at the first end 50A), the cutting component 40 is used to cut one or more slits 54 in the release paper 53, and the air blowing component 60 is used to blow air onto the slits 54 to separate the release paper 53 from the adhesive layer 52 between the slits 54 and the end 50B or the first end 50A. Then, the separation component 30 is used to peel the release paper 53 from the adhesive layer 52 starting from the release paper 53 that has been separated at the end 50B or the first end 50A.

[0048] The release paper separation device 1 for the adhesive-backed strip noise reduction component described in this invention can automatically and conveniently separate the release paper 53 from the adhesive layer 52. Especially when the strip noise reduction component and / or the release paper are relatively soft, or when the ends of the strip noise reduction component are designed with a beveled structure, it is difficult to easily peel the release paper off even by hand. This invention is particularly suitable for quickly peeling the release paper off the strip noise reduction component body in the above situations.

[0049] Optionally, the fixing element 20 of the present invention can be any combination of a power source such as an air source (with a certain pressure), a cylinder, or a motor, and a mechanical claw, mechanical clamp, vacuum suction cup, or needle suction cup as the fixing execution element; similarly, the separating component 30 of the present invention can also be any combination of a power source such as an air source (with a certain pressure), a cylinder, or a motor, and a mechanical claw, mechanical clamp, vacuum suction cup, or needle suction cup as the separating execution element. For example, the fixing element is a combination of a motor and a mechanical clamp, with the motor driving the mechanical clamp to clamp and fix both sides of the sound-absorbing sponge; the separating component is a combination of a cylinder and a vacuum suction cup, with the vacuum suction cup holding the release paper of the peeling part, and then the cylinder driving the vacuum suction cup to move outward to peel off the release paper; or the fixing element is a combination of an air source and a needle suction cup, and the separating component is a cylinder and a mechanical claw, etc. These are not exhaustive examples; specific combinations can be made according to actual needs.

[0050] In addition, the release paper separation device 1 for the adhesive-backed strip noise reduction component of the present invention may also include a positioning element for determining the position of the strip noise reduction component 50. Optionally, the positioning element may be a baffle or a photoelectric switch disposed on the mounting plate 10; and a material collection component 70 disposed on the mounting plate 10 for recycling the peeled release paper 53, so as to realize the automatic recycling of the release paper while peeling off the release paper.

[0051] As one embodiment, the fixing element 20 of the present invention adopts a combination of an air source and a needle suction cup, and the separation component 30 adopts a combination of a cylinder and a vacuum suction cup to illustrate the working principle of the present invention.

[0052] As attached Figures 1 to 10 As shown, the mounting plate 10 of the present invention is fixedly provided with a connecting plate 21 and a needle suction cup 22 (the needle suction cup 22 is connected to an air source not shown) on the connecting plate 21. A photoelectric switch 80 is provided on the mounting plate 10 above the needle suction cup 22. The separation component 30 on the mounting plate 10 includes a swing arm 31, a swing arm cylinder 32 and a plurality of vacuum suction heads 33. One end 311 of the swing arm 31 is rotatably provided on the mounting plate 10 via a rotating shaft or bearing 34. The driving end 321 of the swing arm cylinder 32 is connected to the swing arm 31. The other end 312 of the swing arm 31 is provided with a branch bracket 35. The vacuum suction heads 33 are provided on the branch bracket 35.

[0053] Therefore, when the adhesive-backed strip noise reduction component 50 is vertically conveyed to the release paper separation device 1, the position of the adhesive-backed strip noise reduction component 50 is first detected and determined by the photoelectric switch 80. Then, the cutting component 40 cuts one or more slits in the release paper. Next, the air blowing component 60 blows air into the slits to separate the release paper from the adhesive layer between the slit and the first end 50A or the last end 50B. Then, the needle suction cup 22 is driven by an external driving air source (not shown) to fix the first end 50A or the last end 50B of the adhesive-backed strip noise reduction component 50. At the same time, several vacuum suction heads 33 on the branch bracket 35 adsorb the release paper at the first end 50A or the last end 50B (the state of the branch bracket 35 is shown in the attached figure). Figure 1 As shown in the figure), the swing arm 31 is then moved by the swing arm cylinder 32 to move the branch bracket 35 (the state of the branch bracket 35 is shown in the attached figure). Figure 3 As shown), this allows several vacuum suction heads 33 on the branch support 35 to peel the release paper from the sound-absorbing sponge at the first end 50A or the last end 50B by a certain length. Of course, the above actions and functions can also be achieved through other combinations of fixing elements 20 and separating components 30.

[0054] Furthermore, to prevent incomplete separation of the release paper and adhesive layer between the cut and the first end 50A or the last end 50B due to insufficient air blowing at the cut, the present invention may optionally further include a second swing arm 36 and a second swing arm cylinder 37 in the separation assembly 30. One end 361 of the second swing arm 36 is connected to the drive end 371 of the second swing arm cylinder 37, and the other end 362 of the second swing arm 36 is connected to the branch bracket 35. The second swing arm cylinder 37 is mounted on the swing arm 31. With the above arrangement, the second swing arm 36 can be moved first by the second swing arm cylinder 37, thereby causing the branch bracket 35 to rotate at a small angle (the state of the branch bracket 35 is shown in the attached figure). Figure 2 As shown), a small section of the release paper at the first end 50A or the last end 50B of the branch bracket 35 is peeled off from the sound-absorbing sponge, and then the swing arm 31 is moved by the aforementioned swing arm cylinder 32 to move the branch bracket 35 (the state of the branch bracket 35 is shown in the attached figure). Figure 3 As shown), this allows several vacuum suction heads 33 on the branch support 35 to peel the release paper from the silent sponge at the first end 50A or the last end 50B with a certain length.

[0055] The cutting component 40 and the air blowing component 60 of the present invention can be independently mounted on the mounting plate 10; to save space, the cutting component 40 and the air blowing component 60 can also be integrated and mounted on the mounting plate 10. (See attached diagram) Figure 4 To be continued Figure 6As shown, this embodiment only uses the cutting assembly 40 and the air blowing assembly 60 integrated on the mounting plate 10 as an example for explanation. A cylinder bracket 41 is used to connect the mounting plate 10, and a mounting bracket driver 43 is disposed on the cylinder bracket 41, and a mounting bracket 42 is disposed on the drive end 431 of the mounting bracket driver 43. The mounting bracket driver 43 can drive the mounting bracket 42 to extend and retract. The air blowing assembly includes a nozzle 45, a nozzle driver 44, and an air pipe 49 communicating with the nozzle 45. The nozzle driver 44 is disposed on the mounting bracket 42, and the nozzle 45 is disposed on the drive end 441 of the nozzle driver 44. The nozzle 45 or the air pipe 49 can be clamped by a clamping block 46 disposed on the drive end 46 of the nozzle driver 44. A cutting driver 47 is disposed on the mounting bracket 42, and a metal blade or high-frequency vibrating knife 48 is connected to the drive end 471 of the cutting driver 47. After the adhesive-backed strip noise reduction component 50 is conveyed to the predetermined position, the mounting bracket driver 43 drives the mounting bracket 42 to move toward the strip noise reduction component 50. That is, the mounting bracket driver 43 drives the cutting assembly 40 and the air blowing assembly 60 to move toward the strip noise reduction component 50 until the metal blade or high-frequency vibrating knife 48 pierces the release paper 53. Then, the cutting driver 47 drives the metal blade or high-frequency vibrating knife 48 to move to cut a slit 54 in the release paper 53 (or to cut multiple slits 54 through multiple cuts or multiple blade structures). Then, the air nozzle driver 44 drives the air nozzle 45 to move toward the strip noise reduction component 50 to the slit and blow air, so that the air blowing at the slit 54 makes the slit 54 reach the beginning 50A (as shown in the attached figure). Figure 11B (as shown) or end 50B (as attached) Figure 11A The release paper 53 and adhesive layer 52 are separated (as shown). The nozzle 45 can be arc-shaped, or it can include two or more sub-nozzles arranged in a fan shape to achieve wide-range airflow from the cut 54, facilitating rapid separation of the release paper 53 and adhesive layer 52; additionally, as shown in the attached... Figure 7 As shown, the air nozzle 45 may be provided with a pressing structure 451 so that when the air nozzle 45 is close to the release paper cut, the pressing structure 451 presses the release paper that is in contact with the air nozzle 45 into the body of the strip noise reduction member 50 to form a concave part, thereby expanding the cut space and facilitating the air nozzle 45 to blow air.

[0056] Optionally, a pressure element (not shown) and a pressure driver (not shown) can be provided separately. The pressure element is connected to the driving end of the pressure driver, and the pressure driver is connected to the mounting plate 10. After the release paper is cut, the pressure driver first drives the pressure element to press the release paper that is in contact with the air nozzle 45 into the body of the strip noise reduction member 50 to form a concave part, so as to expand the cut space and also to facilitate the air nozzle 45 to blow air.

[0057] To achieve automated recycling of the release liner after peeling, as shown in the attached... Figure 8 and 10 As shown, the mounting plate 10 of the present invention may also be provided with a take-up assembly 70. The take-up assembly 70 includes a take-up driver 701, a take-up reel 702, a fixing plate 703, and an unloading driver 704. The take-up driver 701 is connected to the take-up reel 702, which passes through the mounting plate 10. The take-up driver 701 is mounted on the fixing plate 703, and the driving end 7041 of the unloading driver 704 is connected to the fixing plate 703. The take-up reel 702 is a fork-shaped structure (such as a double-fork structure, a triangular fork structure, or a structure with more forks) with relatively long fork teeth 7021. When the release paper 53 of the noise reduction component 50 is adsorbed and peeled off by the vacuum suction head 33 and moved to the take-up position below the take-up reel 702 under the drive of the swing arm 31, the unloading driver 704 drives the take-up reel 702 to move downward along the slide rail 706 (the operation process is shown in the attached figure). Figure 9 To be continued Figure 10 (The position change of the take-up reel 702 shown) allows the release paper 53, which has been adsorbed and peeled off by the vacuum suction head 33, to be placed inside the fork-shaped structure. Under the action of the take-up drive 701 driving the take-up reel 702 to rotate, the release paper 53 is wound into a roll, and at the same time, the release paper 53 is completely peeled off from the strip noise reduction component 50. Then, the unloading drive 704 drives the fixing plate 703 to move upward along the slide rail 706, thereby driving the take-up drive 701 and the take-up reel 702 to move upward. Then, the unloading plate 705 provided on the mounting plate 10 separates the release paper roll on the take-up reel 702 from the take-up reel 702 (the operation process is shown in the attached figure). Figure 10 To be continued Figure 9 (The position of the take-up reel 702 is shown to change), and a take-up hopper (not shown) can be set below the take-up reel 702 to receive the release paper roll.

[0058] As attached Figure 11A To be continued Figure 12 As shown, when the strip noise reduction component 50 is vertically conveyed along the conveying trough 90 (that is, the release paper side of the strip noise reduction component 50 is set close to the separation component 30 and the cutting component 40) to the release paper separation device 1, the strip noise reduction component 50 is first placed in a predetermined position by the positioning element, and then one or more cuts are made on the release paper by the cutting component 40. Then, the air blowing component 60 blows air to the cut to separate the release paper from the adhesive layer between the cut and the first end 50A or the last end 50B. Then, the separation component 30 peels the release paper 53 from the adhesive layer 52 starting from the release paper 53 that has been separated at the last end 50B.

[0059] As attached Figure 13As shown, in another embodiment, the positioning element may include a baffle 82 driven by a baffle driver 81 and disposed on the mounting plate 10, thereby achieving the positioning of the strip noise reduction component 50 through the physical obstruction of such a mechanical structure.

[0060] This invention also discloses a method for separating the release paper of an adhesive-backed strip noise reduction component, comprising: a positioning step, wherein the adhesive-backed strip noise reduction component is placed in a predetermined position by using a positioning element such as a photoelectric switch or a mechanical baffle to facilitate subsequent cutting on the release paper; a cutting step, wherein one or more cuts are made in the release paper of the strip noise reduction component by using a blade in a cutting assembly; an air blowing step, wherein air is blown into the cuts of the release paper through an air nozzle in an air blowing assembly (the so-called "air blowing" refers to supplying air to the air nozzle using an air pump or the like) to separate the release paper from the adhesive layer; and a separation step, wherein the release paper that has been separated from the adhesive layer is fixed and moved by a separation assembly to achieve separation of the release paper from the strip noise reduction component.

[0061] In the cutting process, the cutting depth of the release paper is greater than or equal to the thickness of the release paper, and the cutting width of the release paper is less than the width of the release paper; preferably, the cutting depth of the release paper is 0.05 mm to 5 mm, and the cutting width of the release paper is 5 mm to 50 mm.

[0062] Furthermore, in the cutting process, the cut of the release paper is close to any end in the length direction of the strip noise reduction component, so as to facilitate the separation of the release paper from the adhesive layer by blowing air; preferably, the distance between the cut of the release paper and the end is 1 cm to 20 cm.

[0063] To facilitate air blowing, a top-pressing process can be set between the cutting process and the air blowing process. This can be achieved by setting an independent pressure element or by setting a pressure structure on the air nozzle to press the cut of the release paper, thereby expanding the air blowing space at the cut.

[0064] Furthermore, between the release paper and the adhesive at the cut, the nozzle is arc-shaped, or the nozzle includes two or more sub-nozzles and each sub-nozzle is arranged in a fan shape. Therefore, the nozzle can blow air in a straight line, an oscillating manner, or a dispersed manner through multiple sub-nozzles towards the end.

[0065] As attached Figures 14 to 15As shown, the present invention also discloses a bonding device 100 for applying an adhesive-backed strip noise reduction component 50 to the inner wall of a tire, including a tire fixing device 200 for fixing and conveying a received tire 300 to the bonding position; a bonding assembly 400 for applying the adhesive-backed strip noise reduction component 50 to the inner wall of the tire 300; and a release paper separating device 1 as described above. The bonding assembly 400 can be configured to operate in two alternating sets. The release paper separating device 1 transmits the strip noise reduction component 50 after the release paper has been peeled off to the bonding assembly 400, and the bonding assembly 400 winds, rolls, and unwinds the received strip noise reduction component 50 after the release paper has been peeled off, thereby applying the strip noise reduction component 50 to the inner wall of the tire 300.

[0066] This invention also discloses a bonding system (not shown) for applying an adhesive-backed strip-shaped noise-reducing component to the inner wall of a tire. The system includes a cleaning device (such as a laser cleaning device) for cleaning dust, release agents, and other debris from the tire inner wall; a bonding device 100 as described above; and a pressing device (not shown) for ensuring closer contact between the noise-reducing component and the tire inner wall after initial bonding. The bonding system may also include a feeding device for the adhesive-backed noise-reducing component, or it may be manually fed. This bonding system automates functions such as cleaning the tire inner wall, peeling and rolling the release paper from the adhesive-backed noise-reducing component, bonding the noise-reducing component to the tire inner wall, and recycling the release paper.

[0067] As can be seen from the above-disclosed technical content, the release paper separation device for the adhesive-backed strip noise reduction component of the present invention, as well as the bonding equipment and bonding system using it, mainly involves designing and setting a fixing element, a separation component, a cutting component, and an air blowing component on a mounting plate. The fixing element fixes the end of the strip noise reduction component, the cutting component cuts one or more slits in the release paper, the air blowing component blows air onto the slits, and finally the separation component peels off the release paper from the strip noise reduction component. This original technical solution is particularly suitable for release paper peeling when the strip noise reduction component and / or the release paper are relatively soft or when the end of the strip noise reduction component is set with a beveled structure. It has the technical advantages of simple structure and fully automated peeling.

[0068] The above description is only a partial embodiment of this application, and its purpose is to illustrate the technical concept and features of this application. Any equivalent changes or alternative technical solutions that can be easily conceived by those skilled in the art under the guidance of the technical content of this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
