[0025] Please refer to Figure 1 , Figure 1It is a schematic structural diagram of an embodiment of the pasting device provided by the present application. In one aspect of the present application, a pasting device for a sound-absorbing cotton on a rim is provided. The pasting device includes a support table 1, a conveying assembly 2, a pasting assembly 3, a cotton discharging assembly 4, and a controller (not shown in the figure); the support table 1 includes a first accommodating area 11, a second accommodating area 12, and a third accommodating area 13. The first accommodating area 11 communicates with the second accommodating area 12, and the second accommodating area 12 communicates with the third accommodating area 13; the conveying assembly 2 is arranged in the first accommodating area 11; the pasting assembly 3 is arranged in the second accommodating area 12; the cotton discharging assembly 4 is arranged in the third accommodating area 13; the controller is electrically connected to the conveying assembly 2, the pasting assembly 3, and the cotton discharging assembly 4. The controller can control the conveying assembly 2 to convey the rim 5 to the second accommodating area 12, control the cotton discharging assembly 4 to release the sound-absorbing cotton 6 to the second accommodating area 12, and the pasting assembly 3 pastes the sound-absorbing cotton 6 on the rim 5, thereby realizing the automatic conveying of the rim 5, automatic cotton discharging, and automatic pasting, reducing labor costs, and improving production efficiency.

[0026] Specifically, please continue to refer to Figure 2 shown in Figure 2 It is a top view structural diagram of another embodiment of the pasting device for a sound-absorbing cotton on a rim of the present application. The first accommodating area 11 and the second accommodating area 12 are arranged side by side in the first direction D1, the second accommodating area 12 and the third accommodating area 13 are arranged side by side in the second direction D2, and the first direction D1 and the second direction D2 are perpendicular to each other. Through the above arrangement, the interference between the first accommodating area 11 and the third accommodating area 13 can be improved or avoided, so that the functions of the first accommodating area 11, the second accommodating area 12, and the third accommodating area 13 are clear. The first accommodating area 11 is used to realize the automatic conveying of the rim 5, the second accommodating area 12 is used to realize the automatic pasting of the sound-absorbing cotton 6, and the third accommodating area 13 is used to realize the automatic cotton discharging, thereby improving the ability of the conveying assembly 2, the pasting assembly 3, and the cotton discharging assembly 4 to cooperate with each other and improving production efficiency. As Figure 2 shown in, in another specific embodiment, the support table 1 may also include a first platform 14 and a second platform 15. The first platform 14 is arranged along the first direction D1. The first accommodating area 11 and the second accommodating area 12 are provided on the first platform 14. The second platform 15 is connected to the first platform 14 in the second direction D2. The third accommodating area 13 is provided on the second platform 15. The support table 1 is formed by the assembly combination of the first platform 14 and the second platform 15, which can simplify the design and reduce the production cost. In another specific embodiment, the support table 1 may also be formed into an integral structure by injection molding or the like, which can improve the stability.

[0027] In use, the rim 5 is first located in the first accommodating area 11. The conveying component 2 is controlled by the controller to convey the rim 5 to the second accommodating area 12. Then, the cotton output component 4 outputs the sound-absorbing cotton 6 to the second accommodating area 12. Finally, the sound-absorbing cotton 6 is pasted on the rim 5 by the pasting component 3. Further, the controller may include a control system, such as a PLC control system (Programmable Logic Controller), which can synchronously control the conveying speed of the conveying component 2, the pasting action of the pasting component 3, the cotton output speed of the cotton output component 4, etc., to realize the automated production of the rim 5 pasted with the sound-absorbing cotton 6.

[0028] Please continue to combine Figure 1 and Figure 2 In an embodiment of the present application, the pasting device further includes a detection component 7. The detection component 7 includes a first sensor 71 and a second sensor 72. The first sensor 71 is arranged in the first accommodating area 11, and the second sensor 72 is arranged in the second accommodating area 12; the controller is electrically connected to both the first sensor 71 and the second sensor 72; specifically, in response to both the first sensor 71 and the second sensor 72 detecting the presence of the rim 5, the controller controls the conveying component 2 to stop running; in response to the first sensor 71 detecting the presence of the rim 5 and the second sensor 72 not detecting the presence of the rim 5, the controller controls the conveying component 2 to convey the rim 5 to the second accommodating area 12. Through the above structure, the rim 5 can paste the sound-absorbing cotton 6 one by one in sequence on the production line, improving the production efficiency and production quality.

[0029] In a specific embodiment, the first sensor 71 and the second sensor 72 may include light sensors to facilitate detecting the position of the rim 5 and transmitting information to the controller. In use, the rim 5 is placed in the first accommodating area 11. During the process of conveying the rim 5 by the conveying component 2, when passing by the first sensor 71, the first sensor 71 can transmit the information of the presence of the rim 5 to the controller. At this time, the controller needs to receive the information of the second sensor 72. When the second sensor 72 detects the presence of the rim 5, that is, the pasting component 3 and the cotton output component 4 in the second accommodating area 12 are performing the workflow of pasting the sound-absorbing cotton 6 onto the rim 5, the controller receives the information of the presence of the rim 5 and then controls the conveying component 2 to pause the conveying; when the second sensor 72 does not detect the presence of the rim 5, that is, the pasting component 3 and the cotton output component 4 are not working, the controller receives the information of the absence of the rim 5 and then controls the conveying component 2 to convey the rim 5 in the first accommodating area 11 to the second accommodating area 12.

[0030] In an embodiment of the present application, the conveying component 2 includes a plurality of rollers 21 arranged at intervals along the first direction D1, and the first sensor 71 is arranged on the side of the roller 21 in the second direction D2.

[0031] Specifically, the rotation of the rotating roller 21 drives the movement of the rim 5, thereby realizing automatic conveying. The first sensor 71 is arranged on one or both sides of the rotating roller 21 to facilitate detecting the rim 5 located on the rotating roller 21. When it is detected that there is a rim 5 in the second accommodating area 12, the controller can control the rotating roller 21 to stop rotating to pause the conveying of the rim 5. Of course, in another specific embodiment, the conveying assembly 2 can also be composed of a conveyor belt, which is not limited herein.

[0032] In an embodiment of the present application, the detection assembly 7 further includes a camera 73. The camera 73 is located in the second accommodating area 12 and faces the pasting assembly 3. The pasting device further includes an interception assembly 8. The interception assembly 8 includes a first railing 81 and a second railing 82. The first railing 81 is located between the first accommodating area 11 and the second accommodating area 12, and the second railing 82 is located in the second accommodating area 12. The controller is electrically connected to the interception assembly 8. Specifically, in response to the second sensor 72 detecting the presence of the rim 5, the controller controls the first railing 81 to close to intercept the rim 5 in the first accommodating area 11. In response to the camera 73 detecting that the rim 5 has completed pasting the sound insulation cotton 6, the controller controls the second railing 82 to open to facilitate the continued assembly of the tire for the pasted rim 5.

[0033] That is to say, in addition to controlling the rotating roller 21 to stop rotating, the controller can also control the first railing 81 to close to pause the conveying of the rim 5, improve or avoid affecting the rim 5 on which the sound insulation cotton 6 is being pasted, and improve stability and production quality.

[0034] Furthermore, as Figure 1 and Figure 2 shown, the second accommodating area 12 can be provided with a propulsion assembly 9 so that after the rim 5 has completed pasting the sound insulation cotton 6, the second railing 82 is opened and moved to the next production link. In a specific implementation, the propulsion assembly 9 can be composed of several balls. The balls are embedded in the support table 1 and can rotate relative to the support table 1. After the balls come into contact with the rim 5, the rim 5 can be moved by the rotation of the balls. Of course, in another specific implementation, the propulsion assembly 9 can also include other structures, which will not be elaborated herein.

[0035] Please continue to refer to Figure 2 and Figure 3 , Figure 3 is Figure 2An upward view structural schematic diagram of the pasting device for sound-absorbing cotton on the middle rim. In an embodiment of the present application, the pasting assembly 3 includes a positioning fixture 31, the cotton output assembly 4 includes a reel 41, and the controller is electrically connected to both the positioning fixture 31 and the reel 41; the second accommodation area 12 is provided with a predetermined position for pasting the sound-absorbing cotton 6 onto the rim 5. Specifically, in response to the camera 73 detecting that the rim 5 has reached the predetermined position, the controller controls the positioning fixture 31 to fix the rim 5 and controls the reel 41 to release the sound-absorbing cotton 6.

[0036] During use, the camera 73 can also detect whether the rim 5 has reached the predetermined position. If not, it can be corrected by the propulsion assembly 9. After the rim 5 reaches the predetermined position, the positioning fixture 31 can clamp and fix the rim 5 to facilitate the pasting of the sound-absorbing cotton 6. At this time, the controller controls the reel 41 to rotate to release the sound-absorbing cotton 6 and output it onto the rim 5, thereby performing the pasting work of the sound-absorbing cotton 6.

[0037] In a specific embodiment, a through hole 121 penetrating the support platform 1 can be provided at the predetermined position. Before the rim 5 reaches the predetermined position, the positioning fixture 31 passes through the through hole 121 and is located below the second accommodation area 12, in a contracted state, so as to save space and facilitate detection by the camera 73; after the rim 5 reaches the predetermined position, the controller controls the positioning fixture 31 to extend from the through hole 121 and clamp and fix the rim 5 to perform the pasting work of the sound-absorbing cotton 6. During pasting, the positioning fixture 31 can clamp the rim 5 and rotate counterclockwise for one week, so that the sound-absorbing cotton 6 is pasted on the outer peripheral surface of the rim 5, that is, the pasting work of the sound-absorbing cotton 6 is completed. In addition, the positioning fixture 31 is also provided with claws, which can align with the pores of the rim 5 to improve the stability of clamping and fixing, and can also play a role in calibrating the center of the rim 5.

[0038] In an embodiment of the present application, the cotton output assembly 4 further includes a guiding assembly 42, and the guiding assembly 42 is arranged between the positioning fixture 31 and the reel 41 for guiding the sound-absorbing cotton 6 onto the rim 5.

[0039] Specifically, the guiding assembly 42 includes a plurality of guiding rotating shafts 421 arranged at intervals, and a guiding channel 422 is formed between two opposite guiding rotating shafts 421. The sound-absorbing cotton 6 can be guided along the guiding channel 422 to the pasting position on the rim 5, improving accuracy and stability. In a specific embodiment, the guiding assembly 42 can be composed of four nylon rotating shafts, and the four nylon rotating shafts are opposite to each other in pairs. The sound-absorbing cotton 6 passes through the guiding channel 422 between two opposite nylon rotating shafts, which can improve or avoid the situation that the direction of the sound-absorbing cotton 6 deviates and cannot reach the pasting position on the rim 5.

[0040] Furthermore, the guiding assembly 42 is provided with a limiting member to improve or avoid deviation in the transmission direction.

[0041] In one embodiment of the present application, the sound-absorbing cotton 6 includes an adhesive layer 61 and a protective layer 62. The protective layer 62 covers the outer surface of the adhesive layer 61 to protect the adhesiveness of the adhesive layer 61. The cotton output assembly 4 further includes a recovery rotating shaft 43. The recovery rotating shaft 43 is disposed opposite to and spaced apart from the guiding assembly 42 to facilitate the recovery of the protective layer 62. The guiding assembly 42 includes two parts. One part guides the adhesive layer 61 to the rim 5, and the other part guides the protective layer 62 to the recovery rotating shaft 43.

[0042] Specifically, each time a new roll of sound-absorbing cotton 6 is replaced, the protective layer 62 needs to be manually torn off and wound around the recovery rotating shaft 43 through the other part of the guiding assembly 42 to recover the protective layer 62.

[0043] During use, one part of the guiding assembly 42 pulls out the sound-absorbing cotton 6 from the reel 41, then the protective layer 62 is manually torn off and wound around the recovery rotating shaft 43. When the sound-absorbing cotton 6 reaches the pasting position on the rim 5, the positioning fixture 31 can be used to clamp the rim 5 and rotate it for one week, so that the sound-absorbing cotton 6 is completely pasted on the outer peripheral surface of the rim 5, and the pasting work of the sound-absorbing cotton 6 is completed.

[0044] In one embodiment of the present application, the cotton output assembly 4 further includes a push rod 44. The push rod 44 is located between the rim 5 and the guiding assembly 42. The push rod 44 can be pushed towards the rim 5 to press the sound-absorbing cotton 6 onto the rim 5, so that the sound-absorbing cotton 6 is completely pasted on the rim 5, improving the stability of the pasting connection between the sound-absorbing cotton 6 and the rim 5.

[0045] Specifically, when the sound-absorbing cotton 6 reaches the pasting position on the rim 5, the push rod 44 can be pushed forward by the power provided by the air cylinder to press the sound-absorbing cotton 6 onto the rim 5, so that the adhesive layer 61 at one end of the sound-absorbing cotton 6 is pasted on the rim 5, and then the air cylinder retracts to restore the push rod 44.

[0046] In one embodiment of the present application, the cotton output assembly 4 further includes a cutting assembly 45. The cutting assembly 45 is located between the push rod 44 and the guiding assembly 42 and is used to cut the sound-absorbing cotton 6.

[0047] Specifically, when the pasting of the sound-absorbing cotton 6 is completed, the cutting assembly 45 cuts the sound-absorbing cotton 6. On the one hand, it facilitates the separation of the pasted rim 5 for the next step; on the other hand, it also facilitates the arrival of the next rim 5 at the predetermined position for pasting.

[0048] In one embodiment of the present application, the pasting assembly 3 further includes a rolling press assembly 32. The rolling press assembly 32 is rotatably in contact with the outer peripheral surface of the rim 5 to make the sound-absorbing cotton 6 and the rim 5 paste more tightly.

[0049] Specifically, when the sound-absorbing cotton 6 is pasted, the rim 5 and the rolling press assembly 32 are mutually extruded during rotation, which can make the sound-absorbing cotton 6 paste more tightly.

[0050] It should be noted that terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or vertical, but can be slightly inclined; terms such as "parallel" and "perpendicular" do not mean that the fittings are absolutely parallel or perpendicular to each other, but can have a certain angular deviation. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined. In addition, the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the products of this application are usually placed during use. It is only for the convenience of describing the embodiments of this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0051] It can be understood that the meaning of "a plurality of" in this article is at least two, such as two, three, etc., unless there are specific restrictive descriptions. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.
