[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0028] like Figures 1 to 8 As shown, the present invention discloses an online detection device 1 for backing paper with adhesive-backed noise reduction components in silent tires (hereinafter referred to as the online detection device for backing paper), comprising a base 10, a backing paper unrolling device 20 with a feed port 21 and a discharge port 22 arranged on the base 10, the backing paper unrolling device 20 being used to unroll the wound backing paper; a backing paper accommodating mechanism 30 arranged near the feed port 21 of the backing paper unrolling device, the backing paper accommodating mechanism 30 being used to receive the backing paper 100 peeled off from the adhesive-backed noise reduction component and wound into a roll; further comprising a movably arranged material head fixing mechanism 40, the material head fixing mechanism 40 being used to grab the backing paper material head from the backing paper accommodating mechanism 30 and move the backing paper material head to the backing paper unrolling device 20; further comprising a backing paper detection component 50 arranged corresponding to the backing paper unrolling device 20, the backing paper detection component 50 being used to detect the backing paper unrolled at the backing paper unrolling device 20. When in use, after the adhesive-backed noise reduction component is attached to the tire, the backing paper 100 peeled off from the adhesive-backed noise reduction component is received by the backing paper accommodating mechanism 30, the backing paper head is grabbed from the backing paper accommodating mechanism 30 by the head fixing mechanism 40, and the backing paper head is moved to the backing paper unfolding device 20 for fixation, and the backing paper 100 is conveyed forward by the backing paper unfolding device 20 to unfold the wound backing paper, and the unfolded backing paper 100 is detected in real time by the backing paper detection component 50 until the backing paper in the backing paper accommodating mechanism 30 is completely unfolded by the backing paper unfolding device 20 and detected by the backing paper detection component 50, thereby realizing automatic online backing paper detection.

[0029] Through the above arrangement, the backing paper 100 peeled off from the adhesive-backed noise reduction component can be automatically detected, and by detecting whether the backing paper 100 is damaged, it can be confirmed whether the adhesive-backed noise reduction component is defective before being attached to the tire and during the process of being attached to the tire. The above device has a simple structure and is easy to use. It can be combined with the existing silent tire production equipment. When the detected backing paper 100 is defective, it can be fed back to the control system (not shown) in a timely manner, so that the silent tire with the adhesive-backed noise reduction component attached with the corresponding backing paper is transferred to the defective product area or the temporary storage area, so as to better realize the automated production of silent tires.

[0030] like Figure 8 As shown, the backing paper accommodating mechanism 30 of the present invention has a support member 31 and an accommodating element 32, wherein the support member 31 is disposed at one end of the accommodating element 32 for supporting the backing paper 100; the accommodating element 32 has an accommodating element side wall 321, and a backing paper outlet 322 is disposed on the accommodating element side wall 321, and the height of the backing paper outlet 322 is greater than the height of the backing paper. By providing the backing paper outlet 322, when the wound backing paper 100 is placed in the accommodating element 32, the slug of the backing paper is fixed and pulled out from the backing paper outlet 322 by the slug fixing mechanism 40. It should be noted that the accommodating element 32 is only shown as an approximately circular shape in the accompanying drawings, and the accommodating element 32 can also be designed to be other shapes according to actual needs.

[0031] Preferably, a backing paper inlet 323 is provided at one end of the accommodating element 32 away from the supporting member 31. When the noise reduction element fitting head device (the noise reduction element fitting head device is used to fit the noise reduction element to the inner wall of the tire) and the backing paper online detection device are in appropriate positions, the wound backing paper 100 can enter the accommodating element 32 from the noise reduction element fitting head device through the backing paper inlet 323 by gravity, and then be pulled out little by little from the backing paper outlet 322, so as to better realize the combination of the backing paper online detection device and the existing silent tire production equipment, and realize the automated production of silent tires. Of course, the wound backing paper can also be directly passed through the backing paper outlet 322 into the containing element 32, and then pulled out little by little from the backing paper outlet 322. At this time, the size of the backing paper outlet 322 can be adjusted. When the wound backing paper 100 needs to enter the containing element 32, the backing paper outlet 322 becomes larger. When the wound backing paper 100 needs to be pulled out little by little after entering the containing element 32, the backing paper outlet 322 becomes smaller.

[0032] Due to the effect of internal stress, the head and tail of the adhesive-backed noise reduction component attached to the silent tire will easily separate from the inner wall of the tire. Therefore, the quality control of the adhesive at the head and tail of the adhesive-backed noise reduction component is very important, and the detection of the head and tail of the backing paper is also essential. When the head fixing mechanism 40 grabs the backing paper head 101 from the backing paper accommodating mechanism 30, if the grabbing position is inconsistent each time, the amount of backing paper head moved to the backing paper unfolding device 20 will be uncontrollable. When a large amount of head is moved to the backing paper unfolding device 20, the head of the backing paper may exceed the detection area of ​​the backing paper detection component 50, so that part of the backing paper head 101 may be transported to the subsequent process without being detected.

[0033] Therefore, in order to ensure that the position of the material head fixing mechanism 40 is consistent when grabbing the backing paper material head 101, the backing paper online detection device described in the present invention also includes a backing paper material head detection component 60, and the backing paper material head detection component 60 is used to detect the wound backing paper material head 101 in the backing paper accommodating mechanism 30, so as to better control the material head fixing mechanism 40 to grab the backing paper material head from the backing paper accommodating mechanism 30.

[0034] The accommodating element 32 and the supporting member 31 described in the present invention can rotate relative to each other, and also include a rotating driving source 33, the driving end of the rotating driving source 33 is fixed to the accommodating element 32 or the supporting member 31, and is used to drive the accommodating element 32 or the supporting member 31 to rotate, so that the backing paper head 101 placed on the supporting member 31 and the backing paper outlet 322 on the accommodating element 32 are relatively rotated, so that the backing paper head 101 and the backing paper outlet 322 are at a suitable distance, which is convenient for the backing paper head 101 to be pulled out from the backing paper outlet 322, and the length of the backing paper head 101 grabbed by the head fixing mechanism 40 each time can be controlled. Preferably, the accommodating element 32 is fixedly arranged on the base, and the driving end of the rotating driving source 33 can drive the supporting member 31 to rotate relative to the accommodating element 32, thereby driving the wound backing paper 100 to rotate in the accommodating element 32. The fixed accommodating element 32 facilitates the fixed position of the backing paper outlet 322, so that the material head fixing mechanism 40 can fix the backing paper material head from the fixed position through the same movement each time. The following is only described by this method as an example.

[0035] like Figure 2 and 8As shown, preferably, a backing paper head detection port 324 is also provided on the side wall 321 of the accommodation element of the present invention, and the backing paper head detection component 60 is provided corresponding to the backing paper head detection port 324. When the wound backing paper rotates in the accommodation element 32, until the backing paper head 101 is located at the backing paper head detection port 324 and is detected by the backing paper head detection component 60, the support member 31 drives the wound backing paper to stop rotating in the accommodation element 32, and the head fixing mechanism 40 moves to the backing paper outlet 322 to fix and pull out the backing paper head 101. Preferably, the height of the backing paper head detection port 324 is less than the height of the backing paper, so that the backing paper head 101 is restricted when rotating to the backing paper head detection port 324 and will not be bounced open.

[0036] Since the height of the backing paper outlet 322 is greater than the height of the backing paper, in order to prevent the backing paper from being pulled out as a whole from the backing paper outlet 322, the backing paper accommodating mechanism 30 further includes a fixed shaft 34, and the fixed shaft 34 is fixedly disposed on the support member 31. When the rolled backing paper is placed in the accommodating element 32, the fixed shaft 34 fixes the backing paper so that the whole backing paper will not be directly pulled out, but can be pulled out after being unfolded little by little through the backing paper head.

[0037] like Figure 3 and 7 As shown, the backing paper unfolding device 20 of the present invention includes a rotatable first roller group 23, the first roller group 23 is used to convey the backing paper in a first direction (such as the X-axis direction), and also includes an unfolding movement driving mechanism 24, the unfolding movement driving mechanism 24 is connected to the first roller group 23, and is used to drive the first roller group 23 to rotate, the first roller group 23 includes a first active roller 231 and a first pressure roller 232, the first pressure roller 232 can reciprocate along a second direction (such as the Y-axis direction, the second direction is perpendicular to the first direction) to approach the first active roller 231 or move away from the first active roller 231, when the material head fixing mechanism 40 moves the backing paper material head 101 to the position of the first roller group 23, the first pressure roller 232 moves along the second direction to approach the first active roller 231, so that the backing paper is located between the first active roller 231 and the first pressure roller 232, the backing paper is fixed by the first active roller 231 and the first pressure roller 232, and then the first active roller 231 is driven to rotate by the unfolding movement driving mechanism 24 to convey the backing paper forward and unfold the backing paper.

[0038] It should be noted that, since the backing paper is unrolled after being wound, the backing paper 100 cannot be well unrolled in the detection area formed by the backing paper detection component 50 by a group of rollers in the above embodiment. Therefore, as a second embodiment of the backing paper unrolling device 20, the backing paper unrolling device 20 of the present invention includes, in addition to the above-mentioned first roller group 23, a second roller group 25 arranged at a certain distance from the first roller group 23 in the first direction, the first roller group 23 and the second roller group 25 respectively fix the backing paper, the second roller group 25 includes a second active roller 251 and a second pressing roller 252, and the unrolling movement driving mechanism 24 is connected to the first roller group 23 and the second roller group 25 respectively, and is used to drive the first roller group 23 and the second roller group 25 to rotate, so as to transport the backing paper 100 located between the first roller group 23 and the second roller group 25 forward for unrolling. By fixing the backing paper 100 respectively by the first roller group 23 and the second roller group 25, the wound backing paper 100 can be better unfolded, so that the backing paper between the first roller group 23 and the second roller group 25 can be better detected by the backing paper detection component 50. The unfolding movement driving mechanism 24 includes an unfolding movement driving source 241 and a transmission device 242 driven by the unfolding movement driving source 241, and the end of the transmission device 242 away from the unfolding movement driving source 241 is connected to the first active roller 231 and the second active roller 251 respectively, and the transmission device 242 can be a combination of a synchronous belt and a synchronous pulley.

[0039] In order to better detect the backing paper after unfolding, there should usually be no obstruction in the detection area formed by the backing paper detection component 50. In order not to cause obstruction to the backing paper detection component 50, when the material head fixing mechanism 40 moves the backing paper material head 101 from the backing paper accommodating mechanism 30 to the backing paper unfolding device 20, it may avoid the detection area and move the end of the backing paper material head to exceed the range of the backing paper unfolding device 20, thereby making it impossible to fully detect the backing paper material head 101. Therefore, in order to ensure that the backing paper head is also completely detected, the unfolding movement drive mechanism 24 is not only used to drive the first roller group 23 and the second roller group 25 to rotate forward, but also used to drive the first roller group 23 and the second roller group 25 to rotate reversely. When the first roller group 23 and the second roller group 25 rotate forward, the backing paper can be moved along the conveying direction (i.e., the X-axis direction) to unfold the backing paper. When the first roller group 23 and the second roller group 25 rotate reversely, the backing paper moves in the direction opposite to the conveying direction (i.e., the direction opposite to the X-axis) so that the backing paper head 101 can return to the detection area where the backing paper unfolding device 20 is located and be detected by the backing paper detection component 50.

[0040] like Figure 3 and 7As shown, the backing paper unfolding device 20 described in the present invention also includes a first pressure roller moving mechanism 27, which includes a first bracket 271 movably arranged on the base 10, and the first pressure roller 232 is rotatably arranged on the first bracket 271, and also includes a first pressure roller driving source 272 fixedly arranged on the base 10, and the driving end of the first pressure roller driving source 272 is connected to the first bracket 271, and the first pressure roller driving source 272 is used to drive the first bracket 271 to move, thereby driving the first pressure roller 232 on the first bracket 271 to approach the first active roller 231 or move away from the first active roller 231.

[0041] To ensure that the backing paper can be fixed by the second roller group 25, the second pressing roller 252 described in the present invention can move along the second direction close to the second active roller 251 or away from the second active roller 251. Therefore, the backing paper unfolding device 20 described in the present invention also includes a second pressing roller moving mechanism 28, and the second pressing roller moving mechanism 28 includes a second bracket 281 movably arranged on the base 10, and the second pressing roller 252 is rotatably arranged on the second bracket 281, and also includes a second pressing roller driving source 282 fixedly arranged on the base 10, and the driving end of the second pressing roller driving source 282 is connected to the second bracket 281, and the second pressing roller driving source 282 is used to drive the second bracket 281 to move, thereby driving the second pressing roller 252 on the second bracket 281 to approach the second active roller 251 or away from the second active roller 251. When the backing paper is transported by the first roller group 23 and moves to the second active roller 251 , the second pressing roller driving source 282 drives the second pressing roller 252 to approach the second active roller 251 to fix the backing paper between the second pressing roller 252 and the second active roller 251 .

[0042] like Figure 7As shown, in order to better combine the backing paper online detection device of the present invention with the existing silent tire production equipment, the backing paper online detection device of the present invention also includes a backing paper curling mechanism 70 arranged at the discharge port 22 of the backing paper unfolding device, which is used to curl and collect the backing paper unfolded and detected by the backing paper unfolding device 20. Specifically, the backing paper curling mechanism 70 includes a reel 71 with an opening 711, and a curling drive source 72 for driving the reel 71 to rotate, the opening is open at one end of the reel 71 close to the base 10, so that the backing paper head after being unfolded by the backing paper unfolding device 20 can enter the reel opening 711, and also includes a blocking member 73 sleeved on the outside of the reel 71 and movable radially along the reel 71, and a stripping drive source 74 that can drive the blocking member 73 to move radially along the reel, the stripping drive source 74 is fixedly arranged on the base 10, and the driving end of the stripping drive source 74 is connected to the blocking member. When in use, the blocking member 73 is at one end of the reel 71 away from the base 10. After the backing paper is rolled up on the reel 71, the blocking member 73 moves on the reel 71 toward the base 10, so that the rolled backing paper falls off the reel 71. A corresponding collecting device (not shown) can be provided below the reel 71 to collect the rolled backing paper.

[0043] like Figure 4 and 5 As shown, the material head fixing mechanism 40 of the present invention includes a movable material head fixing part 41, which is movably arranged on the backing paper unfolding device 20 through a moving component (not shown), or is movably arranged on an independent bracket through a moving component, and also includes a material head moving driving source 42 that can drive the material head fixing part 41 to move, and the driving end of the material head moving driving source 42 is connected to the material head fixing part 41. Preferably, the material head fixing part 41 is a vacuum suction head, a needle suction head or other clamping mechanism.

[0044] Preferably, the backing paper detection component 50 of the present invention includes a detection light source 51 and a detection camera 52, and the backing paper material head detection component 60 includes a material head detection light source 61 and a material head detection camera 62. Of course, the backing paper detection component 50 and the backing paper material head detection component 60 can also be other visual detection devices. Preferably, the detection light source 51 is arranged between the first roller group 23 and the second roller group 25, and the detection camera 52 is arranged corresponding to the detection light source 51. Specifically, when the detection camera 52 is arranged at a certain distance in front of the detection light source 51, the overall structure of the backing paper online detection device is the most compact.

[0045] Since the curled backing paper will also be easily uneven during the process of being unfolded by the backing paper unfolding device 20, thus affecting the detection of the backing paper detection component 50. Therefore, in order to solve the above technical problems, the backing paper online detection device described in the present invention also includes a backing paper smoothing element (not shown), so that the backing paper passing through the backing paper unfolding device 20 is smoother and easier to be detected by the backing paper detection component. Preferably, the backing paper smoothing element is a blowing nozzle element, and the blowing nozzle element is used to blow air to the backing paper 100 passing through the backing paper unfolding device 20, so that the backing paper is closely attached to the detection light source, making the backing paper smoother and easier to be detected.

[0046] The working principle of the backing paper online detection device described in the present invention is that when the backing paper on the adhesive-backed noise reduction component is completely separated from the adhesive-backed noise reduction component, the wound backing paper 100 is placed in the accommodating element 32 by natural falling or mechanical structure placement, and the rotating drive source 33 drives the accommodating element 32 and the supporting member 31 to rotate relative to each other, so that the backing paper head 101 in the accommodating element 32 moves relative to the backing paper head detection port 324 until the backing paper head detection component 60 detects the end of the backing paper head, and the accommodating element 32 and the supporting member 31 stop rotating relative to each other, as shown in FIG. Figure 4 As shown, the material head fixing mechanism 40 moves to the accommodation element 32, and fixes the backing paper material head 101 from the backing paper outlet 322 of the accommodation element, as shown in FIG. Figure 5 As shown, the backing paper head 101 is moved to the backing paper unfolding device 20, and the backing paper head 101 is placed between the first pressing roller 232 and the first active roller 231 by moving the first pressing roller 232 toward the first active roller 231 for fixing, and then the backing paper 100 is transported forward by the unfolding movement driving mechanism 24, and the backing paper 100 is transported from the accommodating element 32 to the backing paper unfolding device 20 little by little for unfolding, and the backing paper 100 unfolded at the backing paper unfolding device 20 is detected by the backing paper detection component 50. or, after the backing paper is fixed by the first pressing roller 232 and the first active roller 231, the unfolding moving driving mechanism 24 drives the first active roller 231 to rotate in the opposite direction to convey the backing paper head 101 in the direction opposite to the conveying direction of the backing paper, so that the backing paper head 101 moves toward the direction close to the first pressing roller 232 and the first active roller 231, and the backing paper head 101 is placed in the detection area formed by the backing paper detection component 50, and the backing paper head 101 is detected by the backing paper detection component 50, such as Figure 6As shown, the unfolding movement driving mechanism 24 then drives the first active roller 231 to rotate forward to convey the backing paper 100 along the conveying direction, and the backing paper is fixed after passing through the second roller group 25. The backing paper 100 is unfolded and conveyed between the first roller group 23 and the second roller group 25, and the unfolded backing paper is detected by the backing paper detection component 50; optionally, after the backing paper head 101 passes through the backing paper detection component 50 and enters the opening 711 of the reel and is fixed, the curling driving source 72 then drives the reel 71 to rotate to curl the backing paper 100 on the reel 71, and after the curled backing paper in the accommodating element 32 passes through the detection of the backing paper detection component 50 and is curled again on the reel 71, the blocking member 73 moves on the reel 71 toward the backing paper that is curled into a roll, so that the backing paper falls from the reel 71, thereby completing the automatic detection of the backing paper.

[0047] The present invention also provides a device 1000 for laminating noise reduction components with adhesive backing, comprising a frame 2, a laminating head device 3 with adhesive backing noise reduction components movably arranged on the frame 2, and a tire support 4, wherein the tire support 4 is used to fix the tire, and the laminating head device 3 with adhesive backing noise reduction components is used to roll up the noise reduction components with adhesive backing, separate the backing paper from the noise reduction components with adhesive backing, and laminar the noise reduction components with adhesive backing into the tire; and also comprises the above-mentioned backing paper online detection device 1, wherein the backing paper online detection device 1 is used to receive the backing paper separated from the noise reduction element and detect whether the backing paper is damaged, so as to confirm whether the noise reduction components with adhesive backing laminated into the tire are defective, and then judge whether the corresponding tire is qualified.

[0048] Preferably, the noise reduction element laminating head device 3 can move between the noise reduction element laminating position (at this position, the noise reduction element laminating head device laminates the noise reduction element with the separated backing paper into the tire) and the backing paper unloading position (at this position, the noise reduction element laminating head device unloads the backing paper peeled off after the noise reduction element is laminated to the tire), and the backing paper online detection device 1 can move between the backing paper detection working position (at this position, the backing paper online detection device detects the backing paper) and the above-mentioned backing paper unloading position. When the noise reduction element laminating head device 3 and the backing paper online detection device 1 are both at the backing paper unloading position (it should be noted that the "both at the backing paper unloading position" mentioned in the present invention does not mean complete overlap in spatial position, and there may be a certain distance in a certain direction to avoid collision), the backing paper online detection device 1 receives the backing paper from the noise reduction element laminating head device 3, and the backing paper falls into the backing paper online detection device by gravity, thereby realizing a simple and reasonable layout of the entire laminating equipment.

[0049] The present invention also provides a backing paper detection method, comprising the following steps: S1: placing the backing paper 100 separated from the adhesive-backed noise reduction component and rolled up in the backing paper accommodating mechanism 30, specifically in the accommodating element 32; S2: The material head fixing mechanism 40 fixes the backing paper material head 101 in the backing paper accommodating mechanism 30 and moves the backing paper material head 101 to the backing paper unfolding device 20; S3: The backing paper head 101 is fixed by the backing paper unfolding device 20. Specifically, the first pressing roller 232 in the backing paper unfolding device 20 approaches the first active roller 231 along the second direction, so that the backing paper head 101 is placed between the first pressing roller 232 and the first active roller 231 and is fixed; S4: The backing paper is unfolded by the backing paper unfolding device 20, and the unfolding movement driving mechanism 24 drives the first active roller 231 to rotate in the forward direction, so that the backing paper moves along the first direction through the first roller group 23 and is unfolded continuously; S5: The backing paper detection component 50 performs real-time detection on the backing paper unfolded by the backing paper unfolding device 20 and feeds back to the control system, so that the backing paper is unfolded and detected at the same time; when the backing paper detection component detects that the backing paper is damaged, the tire with the noise reduction element affixed is judged as a defective product, and the control system operates the relevant structure to transfer the tire to the defective product area or the temporary storage area for defective tire processing; when the backing paper detection component detects that the backing paper is not damaged, the tire with the noise reduction element affixed is judged as a qualified product, and the control system operates the relevant structure to continue the normal circulation of the tire.

[0050] Optionally, in order to enable the backing paper head 101 placed in the accommodating element 32 to be detected, so that the amount of the backing paper head 101 fixed by the head fixing mechanism 40 can be controlled, the following step S12 is also included between S1 and S2: the support member 31 and the accommodating element 32 rotate relative to each other, so that the back paper placed on the support member 31 and the back paper head detection port 324 on the accommodating element 32 rotate relative to each other, and the back paper head detection component 60 detects the back paper head 101 in the accommodating element 32 through the back paper head detection port 324; when the back paper head detection component detects the back paper head, the support member 31 and the accommodating element 32 stop rotating relative to each other.

[0051] In order to ensure that the backing paper head 101 can be detected by the backing paper detection component 50 at the backing paper unfolding device 20, thereby realizing a full inspection of the backing paper, the following step S34 is also included between S3 and S4: the unfolding movement drive mechanism 24 drives the first active roller 231 to rotate in the opposite direction, so that the backing paper moves in a direction opposite to the backing paper conveying direction, so that the backing paper head 101 first returns to the starting position of the feed port of the backing paper unfolding device 20, and then is detected by the backing paper detection component 50.

[0052] The present invention mainly provides an online detection device for backing paper, which realizes automatic online detection of backing paper by unfolding and detecting the backing paper 100 separated from the noise reduction member with adhesive backing; by arranging a backing paper accommodating mechanism 30 at the feed inlet 21 of the backing paper unfolding device, the backing paper accommodating mechanism 30 includes an accommodating element 32 with a backing paper outlet 322 on the side wall, so that the backing paper released from the accommodating element 32 can directly enter the backing paper unfolding device 20 for unfolding, thereby realizing that the backing paper is unfolded and detected at the same time; the accommodating element 32 and the supporting member 31 can rotate relative to each other to drive the supporting member The backing paper on the backing paper 31 rotates relative to the backing paper head detection port 324 on the accommodating element, and cooperates with the backing paper head detection component 60 to detect the backing paper head 101 in the accommodating element, so that the position of the backing paper head grabbed by the head fixing mechanism 40 each time is fixed; the first roller group 23 and the second roller group 25 are driven to rotate forward and reversely by the unfolding movement driving mechanism 24, so that the backing paper head 101 can return to the backing paper unfolding device 20 for head detection; the backing paper curling mechanism 70 is set so that the backing paper 100 after being detected can be rolled up again for collection, so as to better realize the online automatic detection of the backing paper. The backing paper online detection device provided by the present invention has a simple structure and is easy to use. It can be easily combined with the existing noise reduction component bonding equipment to realize the on-line detection of the backing paper separated from the noise reduction component with adhesive backing. When the backing paper is defective, it can be fed back to the noise reduction component bonding equipment in time, and the tire to which the defective backing paper belongs can be immediately identified and processed, so as to realize the full process automatic production of the noise reduction component with adhesive backing to be bonded in the tire.
