Description

Technical Field

[0001] This utility model relates to the field of belt layer bonding technology, and in particular to an automatic belt layer bonding device. Background Technology

[0002] Currently, there are two main types of bonding equipment used in the automatic cutting and bonding feeder of belt layers for three-drum forming machines. One type has a two-layer structure. The upper surface of the long conveyor belt in the lower layer receives the cut belt layer, then transfers it to the lower surface of the short conveyor belt in the upper layer. Finally, the short conveyor belt extends from the upper layer to bond the belt layer onto the belt drum. The other type has a three-layer structure. The lower layer is a swing frame. The upper surface of the long conveyor belt in the middle layer receives the cut belt layer, then transfers it to the lower surface of the short conveyor belt in the upper layer. Finally, the long and short conveyor belts simultaneously extend the belt layer onto the belt drum to complete the bonding. Both types of bonding equipment suffer from the problem of uncontrollable transfer process of the belt layer between the two conveyor belts, which ultimately affects the quality of automatic bonding of the belt layer onto the belt drum.

[0029] Example 1

[0030] Combination Figures 1-4 An automated bonding device for belt layers, comprising:

[0031] Two automatic belt layer bonding devices 1 and a frame 2 are provided. The frame 2 is divided into upper and lower layers. The two automatic belt layer bonding devices 1 are installed on the upper and lower layers of the frame 2, respectively. The automatic belt layer bonding device 1 includes a swing frame 7 and a bonding frame 8. The swing frame 7 is installed on the upper part of the bonding frame 8 through a linear guide pair 9.

[0032] The swing frame 7 includes a telescopic cylinder 10 and a bearing 6. The telescopic cylinder 10 is installed on the upper part of the swing frame 7. The swing frame 7 is connected to the fitting frame 8 through the cylinder rod of the telescopic cylinder 10. The telescopic cylinder 10 can drive the fitting frame 8 to extend and retract relative to the swing frame 7 along the linear guide pair 9. The bearing 6 is installed at the rear end of the swing frame 7. The swing shaft of the swing frame 7 is fixed to the frame 2 through the bearing 6. When the swing frame 7 is driven, the swing frame 7 can swing up and down on the frame 2 around the swing shaft.

[0033] In this embodiment, the automatic belt layer bonding device 1 is fixed to the frame 2 by bearing 6. The front side of the swing frame 7 can be connected to the drive mechanism. The drive mechanism drives the swing frame 7 to swing up and down around the swing axis on the frame 2, thereby driving the automatic belt layer bonding device 1 to swing up and down on the frame 2. The drive mechanism includes a cylinder and an electric cylinder.

[0034] The bonding frame 8 includes a conveyor motor 11, a conveyor roller 12, a conveyor belt 13, and a magnetic suction plate 14. The conveyor motor 11 is installed at the front end of the bonding frame 8, and the conveyor roller 12 is installed at the front end of the conveyor motor 11. The conveyor belt 13 is installed at the lower part of the bonding frame 8, and the magnetic suction plate 14 is installed below the conveyor belt 13. The magnetic suction plate 14 is in close contact with the lower inner side of the conveyor belt 13 and can attract the belt layer 15. The conveyor motor 11 can drive the conveyor roller 12 to drive the conveyor belt 13, and at the same time, the magnetic suction plate 14 can attract the belt layer 15, so that the belt layer 15 can be conveyed by adhering to the lower surface of the conveyor belt 13.

[0035] In this embodiment, the conveyor motor 11 is a servo motor, which has an internal encoder that can record the number of motor revolutions, i.e., the number of rotations of the motor; the length of the conveyor belt 13 is sufficient to convey the entire belt layer 15 with the longest rubber material length, and the belt layer 15 is a belt layer containing steel wire.

[0036] The bonding frame 8 also includes a pneumatic pressure roller 16 and a 3D camera 17. The pneumatic pressure roller 16 is installed at the rear end of the bonding frame 8. The pneumatic pressure roller 16 can press the belt layer 15 onto the lower surface of the conveyor belt 13. The 3D camera 17 is installed at the rear of the bonding frame 8 and is located below the bonding frame 8. The 3D camera 17 is used to detect and record the head position of the belt layer 15 when the conveyor belt 13 conveys the belt layer 15, and to scan the overall outline of the belt layer 15 to obtain the outline data of the belt layer 15.

[0037] like Figure 5 As shown, the automatic belt layer bonding equipment preferably further includes: a belt drum 5, which is located on the front side of the frame 2 and below the tread bonding device 4.

[0038] In this embodiment, combined with Figure 5 The conveyor belt 13 can transport the belt layer 15 and attach it to the belt drum 5.

[0039] Preferably, the automatic belt layer bonding equipment further includes a tread bonding device 4, which is installed at the front end of the frame 2 and located above the two automatic belt layer bonding devices 1. The tread bonding device 4 can swing up and down on the frame 2.

[0040] In this embodiment, the tread bonding device 4 is used to bond the tread onto the belt drum 5.

[0041] In this embodiment, one of the belt layer conveying devices 3 is installed on the upper layer of the frame 2 and is located behind the belt layer automatic bonding device 1 installed on the upper layer of the frame 2. The other belt layer conveying device 3 is installed on the lower layer of the frame 2 and is located behind the two belt layer automatic bonding devices 1 installed on the lower layer of the frame 2.

[0042] Preferably, the automatic bonding equipment for the belt layer further includes: two belt layer conveying devices 3, two CCD cameras 18, and two light sources 19. The two belt layer conveying devices 3 are all installed at the rear end of the frame 2 and are located behind the two automatic bonding devices 1. The two CCD cameras 18 and the two light sources 19 are also installed on the frame 2. The two CCD cameras 18 are located above the front end of the two belt layer conveying devices 3, and the two light sources 19 are located below the front end of the two belt layer conveying devices 3. The CCD cameras 18 and the light sources 19 are used to detect the lateral offset position of the belt layer 15.

[0043] In this embodiment, one CCD camera 18 is located above the belt layer conveying device 3 installed on the upper layer of the frame 2, and the other CCD camera 18 is located above the belt layer conveying device 3 installed on the lower layer of the frame 2, that is, located between the two belt layer conveying devices 3; and one light source 19 is located in the gap between the belt layer automatic bonding device 1 and the belt layer conveying device 3 installed on the upper layer of the frame 2, and the other light source 19 is located in the gap between the belt layer automatic bonding device 1 and the belt layer conveying device 3 installed on the lower layer of the frame 2.

[0044] like Figure 6 As shown, the belt layer conveying device 3 further includes a conveying roller bed 20, on which an electric cylinder is installed. The electric cylinder can drive the entire belt layer conveying device 3 to move in a lateral position.

[0045] The working principle of the automatic belt layer bonding device provided in this embodiment is as follows:

[0046] When the automatic belt layer bonding device 1 is working normally, the conveying roller beds 20 of the two belt layer conveying devices 3 can respectively convey the belt layers 15 located on the upper and lower layers of the frame 2 forward, and the two automatic belt layer bonding devices 1 respectively bond the belt layers 15 distributed on the upper and lower layers of the frame 2 onto the belt drum 5. Their working principles are the same.

[0047] Taking one of the belt layer conveying devices 3 as an example, when the head of the belt layer 15 enters the rear side of the bonding frame 8 through the gap between the belt layer automatic bonding device 1 and the belt layer conveying device 3, the belt layer 15 is pressed onto the lower surface of the conveyor belt 13 by the pneumatic pressure roller 16, and is conveyed forward tightly against the lower surface of the conveyor belt 13 under the adsorption of the magnetic suction plate 14 below the conveyor belt 13. When the belt layer 15 starts to be conveyed forward from the gap between the belt layer automatic bonding device 1 and the belt layer conveying device 3, during this conveying process, the CCD camera 18 determines the deviation of the belt layer 15 by detecting the image of the light emitted by the light source 19 blocked by the belt layer 15. Then, the electric cylinder installed on the belt layer conveying device 3 drives the belt layer conveying device 3 to make real-time fine adjustments in the lateral position, thereby ensuring that the belt layer 15 can be completely aligned with the conveyor belt 13 after being conveyed to the conveyor belt 13.

[0048] Next, as the belt layer 15 is conveyed forward by the conveyor belt 13 and passes through the detection area of ​​the 3D camera 17, when the 3D camera 17 can detect the head position of the belt layer 15, the conveyor motor 11 starts recording the motor revolutions through its internal encoder. When the 3D camera detects the tail position of the belt layer 15, the internal encoder stops recording the motor revolutions. During this process, the 3D camera 17 scans the overall contour of the belt layer 15 to obtain scan data, and obtains the conveying distance of the conveyor belt in the above process by recording the motor revolutions of the conveyor motor 11, thereby determining the length of the belt layer 15. Combining the scan data and the length of the belt layer 15, the contour data of the entire belt layer 15 is calculated.

[0049] When the belt layer 15 is conveyed and approaches the front end of the conveyor belt 13, the automatic belt layer bonding device 1 swings downward. At this time, the conveyor belt 13 stops conveying the belt layer 15, and then the automatic belt layer bonding device 1 continues to swing downward to the bonding position, even if the distance between the conveyor belt 13 and the belt drum 5 is just enough to ensure that the belt layer 15 can pass through. At this time, the conveyor belt 13 continues to convey the belt layer 15, and the belt drum 5 rotates synchronously. During the process of the conveyor belt 13 continuing to convey the belt layer 15, the belt drum 5 is finely adjusted in the lateral position according to the contour data through the 3D camera 17, thereby ensuring the bonding accuracy of the belt layer 15 on the belt drum 5.

[0050] It should be noted that, as Figure 1 As shown, in the initial state, both the belt layer automatic bonding device 1 and the tread bonding device 4 are in the upper waiting position.

[0051] like Figure 7As shown, when the belt layer 15 located on the lower layer of the frame 2 is conveyed and bonded to the belt drum 5, the tread bonding device 4 and the automatic belt layer bonding device 1 installed on the upper layer of the frame 2 are in the upper waiting position. The bonding frame 8 installed on the automatic belt layer bonding device 1 on the lower layer of the frame 2 extends out and swings downward to the bonding position to bond the belt layer 15 located on the lower layer of the frame 2.

[0052] like Figure 8 As shown, when the belt layer 15 located on the upper layer of the frame 2 is conveyed and bonded to the belt drum 5, the tread bonding device 4 and the automatic belt layer bonding device 1 installed on the lower layer of the frame 2 are in the upper waiting position. The bonding frame 8 installed on the automatic belt layer bonding device 1 on the upper layer of the frame 2 extends out and swings down to the bonding position to bond the belt layer 15 located on the upper layer of the frame 2.

[0053] like Figure 9 As shown, when the tire tread is being bonded, the automatic belt layer bonding device 1 located on the upper and lower layers of the frame 2 is in the lower waiting position, and the tire tread bonding device 4 swings down to the bonding position to bond the tire tread.

[0054] The beneficial effects of the automatic belt layer bonding device provided in this embodiment are as follows:

[0055] The bonding equipment provided in this embodiment has a two-layer structure. The upper layer mainly consists of a swing frame, and the lower layer mainly consists of a long conveyor belt capable of supporting the longest possible length of the adhesive material. The lower surface of this long conveyor belt is used to pick up the cut belt layer. Then, the lower long conveyor belt extends forward relative to the upper swing frame under the drive of a cylinder, directly extending the belt layer onto the belt drum for bonding. The bonding equipment provided in this embodiment eliminates the problem of transferring the belt layer between the two conveyor belts, avoiding the impact of the transfer process and ensuring a better bonding effect.
