Please refer to Figure 3 The tire claw 41 is rotatably mounted with a rotating rubber ring 413 on the outer side, the fixed claw 411 is mounted with a rotating motor 42 on the upper end, the rotating motor 42 is used to drive the rotating rubber ring 413 of the fixed claw 411, the mounting chuck 33 is fixedly mounted with a clamping drive 43, the clamping drive 43 is used to drive the clamping claw 412, please refer to Figure 1 and Figure 2 , further comprising a first sensor 51, a second sensor 52, a third sensor 53 and a fourth sensor 54. The first sensor 51 is fixedly mounted on the upper end of the input belt 21 located in the detection chamber 1, and the second sensor 52 is fixedly mounted on the lower end of the output belt 22 located in the detection chamber 1. Please refer to Figure 4 The third sensor 53 is slidably mounted at the center of the mounting chuck 33 , the third sensor 53 is connected with an extension drive, and the fourth sensor 54 is fixedly mounted on the outer side of the mounting chuck 33 .

[0037] Specifically, the tire is transported in the detection chamber 1 through the input belt 21 and the output belt 22, the reversing column 31 is installed between the two conveyor belts 2, and a tire claw 41 is provided on the reversing rod 32 to grab the tire and move it from the input belt 21 to the output belt 22. At the same time, a rotating motor 42 is provided on the fixed claw 411 to drive the rotating rubber ring 413 to rotate the tire between the tire claws 41, so that the third sensor 53 and the fourth sensor 54 provided on the mounting chuck 33 scan the inside and outside of the tire, and at the same time, the first sensor 51 and the second sensor 52 are respectively provided at the ends of the input belt 21 and the output belt 22 to scan the two ends of the tire.

[0038] In this way, by setting up the tire claw 41 that can drive the tire to rotate during the clamping process, the tire can be scanned on the inside and outside during the transfer process, and at the same time, the scanning of both ends of the tire is completed at both ends of the input belt 21 and the output belt 22, thereby reducing the waiting time during the tire detection process and improving the efficiency of tire detection.

[0039] In some feasible ways, the detection room 1 is used to isolate external light, and by setting lights, the ambient light of the detection environment is kept as stable as possible to reduce the impact of ambient light on the detection results. The reversing column 31 is a cylinder fixed to the ground, and a reversing drive is installed in the top of the reversing column 31. A reversing rod 32 is installed at the output end of the reversing drive. A mounting chuck 33 is installed at both ends of the reversing rod 32. The two conveyor belts 2 are respectively the input belt 21 and the output belt 22, which are located on both sides of the reversing column 31. The reversing rod 32 is rotated by the reversing drive to transfer the tire on the input belt 21 to the output belt 22.

[0040] The mounting chuck 33 is a circular disc, the tire claw 41 is cylindrical, the outer layer of the wheel rubber ring 413 is a rubber material, so as to drive the tire to rotate, and a slidable clamping claw 412 is provided, and the clamping claw 412 is driven by the clamping drive 43 to clamp the tire. During installation, the clamping claw 412 is set in front of the rotation direction of the reversing rod 32, so that the clamping claw 412 expands outward and crosses the tire, and then the fixed claw 411 contacts the tire, and then the clamping claw 412 retracts to complete the clamping action. During installation, the output belt 22 is lower than the input belt 21, and after the tire is transferred to the top of the input belt 21, it is released to fall.

[0041] The first sensor 51, the second sensor 52, the third sensor 53 and the fourth sensor 54 are all commonly used image vision sensors in the field of tire detection. They are tested by taking photos and transmitting them back to the computer for comparison with the preset standard pictures. The first sensor 51 is installed on the top of the first sensor 51 to obtain the image of the upper end of the tire. The second sensor 52 is installed at the lower end of the output belt 22 on the side facing the rotation direction. When the tire is transferred to the side of the output belt 22, the image of the lower end of the tire is obtained. The third sensor 53 and the fourth sensor 54 are respectively installed at the center and the outside of the mounting chuck 33. The tire rotates and continuously takes pictures to obtain the unfolded image of the tire circumference. A light source can be set at the position of the third sensor 53 to obtain the inner image. At the same time, an electric push rod is set at the center of the mounting chuck 33 as an extension drive. The third sensor 53 is installed at the output end of the extension drive. After the tire is clamped, the extension drive extends the third sensor 53 to the center of the tire. Among them, the reversing rod 32 is a rotating part. The electrical appliances on the reversing rod 32 are powered by an electric slip ring, and a wireless module is set for signal transmission.

The receiving ring 23 is installed obliquely downward toward the end of the output belt 22, and the highest point of the receiving ring 23 is lower than the input belt 21 by at least a tire thickness.

[0043] In general, by providing the receiving ring 23, it is convenient to dispose the second sensor 52 at the tire stop position, so as to better obtain the image of the lower end of the tire.

The output end of the clamping drive 43 is provided with a clamping column 333, and both ends of the clamping column 333 are respectively slidably installed in the radial through holes of the rotating column 332.

[0046] In combination with specific usage scenarios, the two clamping claws 412 are linked by the clamping column 333 to facilitate synchronous driving of the clamping drive 43 and better complete the clamping work.

[0047] In some feasible ways, two circular retaining rings are fixedly provided at the ends of the clamping claw 412, and the circular retaining rings are respectively located at both ends of the mounting chuck 33 to reduce the shaking of the clamping claw 412. The clamping drive 43 can be selected as a motor and a screw structure, and the clamping column 333 is threadedly connected to the screw.

[0052] It should be understood that by providing the arc frame 24, the tire is lifted when the reversing rod 32 drives the tire to move, reducing the force required for the tire claw 41 to clamp, thereby reducing tire deformation and facilitating more accurate image acquisition. In order to reduce the friction of the arc frame 24, a plurality of rollers 241 are rotatably mounted on the upper end of the arc frame 24.
