[0023] The working principle and beneficial effects of the above technical solution are: Working principle: The tire tread defect detection system provided by the present invention coordinates the operation of various mechanisms through the controller 9. The base plate 1 serves as the supporting base of the entire system, and the tread detection mechanism 2 is responsible for placing and preliminarily detecting the tire tread. The position adjustment mechanism 5 can accurately adjust the position of the lifting and placing mechanism 6 in the horizontal direction according to the instructions of the controller 9, so that tires of different sizes or detection requirements can be placed in the tread detection mechanism 2. The lifting and placing mechanism 6 is responsible for moving in the vertical direction to grab, carry or place the tire. All mechanisms are electrically connected to the controller 9 to realize automatic control and data transmission.

[0024] Beneficial effects: The present invention realizes the automation and intelligence of tire tread defect detection through integrated design, and improves the detection efficiency and accuracy. The tread detection mechanism 2 can detect tread defects from multiple angles. At the same time, since each mechanism can be uniformly dispatched by the controller 9, the system has strong flexibility and scalability, and can adapt to the detection requirements of tires of different models and specifications.

[0025] Example 2 On the basis of Example 1, Figure 1-Figure 3 , Figure 5As shown, the tread detection mechanism 2 includes: a detection box 21, the detection box 21 is fixedly installed on the top of the base plate 1, an opening 22 is opened in the center of the top of the detection box 21, an electric lifting column 23 is fixedly installed in the center of the bottom wall of the detection box 21, a horizontal support plate 24 is fixedly installed on the top movable end of the electric lifting column 23, a bracket 25 is fixedly installed on the top of the support plate 24, the top of the bracket 25 is rotatably connected to the vertical rotating shaft 26, the top of the rotating shaft 26 is fixedly connected to the rotating disk 27, and a plurality of lighting lamps 28 are fixedly installed on the top wall and left and right side walls inside the detection box 21.

[0026] The visual inspection mechanism 3 includes: an electric telescopic rod 31, a pair of electric telescopic rods 31 are symmetrically fixedly installed on the left and right inner walls of the inspection box 21, the movable end of the electric telescopic rod 31 near the opening 22 is fixedly connected to a rotating support 32, the top of the rotating support 32 is rotatably connected to a rotating shaft 33, the rotating shaft 33 is arranged along the front and rear direction, the top of the rotating shaft 33 is fixedly connected to a high-speed camera 34, the high-speed camera 34 is used to detect and record the tire tread image, the high-speed camera 34 is electrically connected to the controller 9, the front end of the rotating shaft 33 is fixedly connected to a worm gear 35, the bottom end of the worm gear 35 is meshed and connected to a worm 36 along the left and right directions, the worm 36 is fixedly connected to the output shaft end of a rotating motor 37 near the center end, the rotating motor 37 is fixedly connected to the rotating support 32, and a dimension measurement sensor 38 is fixedly installed near the center end of the rotating support 32.

[0027] Working principle of the above technical solution: Based on Example 1, Example 2 further refines the structure of the tread detection mechanism 2 and the visual detection mechanism 3. When the lifting and placing mechanism 6 grabs the tire to be tested and slides to the top of the opening 22 under the operation of the position adjustment mechanism 5, the lifting and placing mechanism 6 closes downward with the tread detection mechanism 2 and releases the tire to be tested onto the support plate 24; the tread detection mechanism 2 adjusts the height of the support plate 24 through the electric lifting column 23, thereby adjusting the position of the tire. The design of the rotating disk 27 and the rotating shaft 26 allows the tire to rotate during the detection process so as to fully detect the tread. The lighting lamp 28 provides sufficient light to ensure that the high-speed camera 34 can clearly capture the tread image. The visual detection mechanism 3 adjusts the position of the high-speed camera 34 through the electric telescopic rod 31, and the rotating motor 37 drives the worm 36 and the worm wheel 35 to rotate, thereby driving the rotating shaft 33 and the high-speed camera 34 to rotate around the rotating shaft to achieve multi-angle shooting. The size measurement sensor 38 is used to measure the size parameters of the tire.

[0028] Beneficial effects: This technical solution realizes all-round and multi-angle detection of tire tread by adding components such as electric lifting column 23, rotating disk 27 and visual detection mechanism 3, thereby improving the comprehensiveness and accuracy of detection. At the same time, the addition of size measurement sensor 38 enables the system to automatically record the size information of the tire, providing data support for subsequent defect analysis and processing.

[0031] Working principle of the above technical solution: Based on Example 2, Example 3 adds detailed designs of the clamp mechanism 4 and the position adjustment mechanism 5. The clamp mechanism 4 fixes the tire to be tested through components such as the annular wall 41, the vertical plate 42 and the wedge block 43 to prevent it from moving or rotating during the detection process. The position adjustment mechanism 5 realizes precise positioning of the tire in the horizontal direction through components such as the linear slide rail and the electric sliding seat 52. The displacement sensor 55 is used to monitor the position information of the electric sliding seat 52 in real time.

[0032] When the electric belt mechanism 29 is working: the controller 9 drives the belt motor 211 to operate, the belt motor 211 drives the second pulley 212 to rotate, and the second pulley 212 drives the first pulley 210, the rotating shaft 26, and the rotating disk 27 to rotate synchronously through the belt transmission; Specific work: 1. Tire placement and clamping mechanism 4 work: The position adjustment mechanism 5 is adjusted downward to place the tire to be inspected on the rotating disk 27 of the tread inspection mechanism 2 to ensure that the center of the tire is aligned with the center of the rotating disk 27 .

[0033] The clamp mechanism 4 fixes the tire through components such as annular wall 41, vertical plate 42 and wedge block 43.

[0035] Beneficial effects: This technical solution ensures the stability and accuracy of the tire during the detection process by adding components such as the clamp mechanism 4 and the position adjustment mechanism 5. The design of the clamp mechanism 4 enables the tire to be firmly fixed, avoiding detection errors caused by tire movement or rotation. The addition of the position adjustment mechanism 5 and the displacement sensor 55 improves the automation and accuracy of the system.

The algorithm analyzes the image data, automatically identifies defects on the tire tread, such as scratches, bubbles, cracks, etc., and outputs information such as the defect location, type and size to the display screen.

[0042] 4. Result output and processing: After the test is completed, the controller 9 outputs the test results to the display screen, and the operator can classify the tires according to the test results. For qualified products, they can be sent to the next process; for unqualified products, the cause of the defects needs to be further analyzed and corresponding improvement measures need to be taken.

[0043] Working principle: Based on Example 2, Example 4 describes in detail the structure and working principle of the lifting and placing mechanism 6 and the grasping mechanism 7. The lifting and placing mechanism 6 drives the lifting and placing screw 65 to rotate through the lifting motor 63, thereby driving the internal threaded tube 68 and the T-shaped bracket 69 and other components to move up and down along the vertical guide rail 66. The grasping mechanism 7 drives the vertical shaft and the bevel gear 1 75 to rotate through the servo motor 73. The bevel gear 1 75 drives the four bevel gears 2 82 and the screw 2 81 to rotate synchronously. The screw 2 81 drives the sliding sleeve 84 and the support rod 1 85 to slide outward along the guide rod 88 to open the four arc clamping plates 86. The arc clamping plates 86 firmly hold the tire open. When the light shield 71 moves down to the closed opening 1 22, it does not move, but the T-shaped bracket 69 continues to slide down until the tire is placed in the clamping mechanism 4, and then runs in the reverse direction. The height sensor 76 and the distance sensor 87 are used to monitor the position of the grasping mechanism 7 and the size information of the tire in real time.

[0044] Beneficial effects: This technical solution realizes the automated grabbing, handling and placement of tires by adding components such as the lifting and placing mechanism 6 and the gripping mechanism 7. The design of the lifting and placing mechanism 6 enables the system to adjust the height and position of the tire according to different detection requirements. The gripping mechanism 7 achieves stable gripping and precise positioning of the tire through the precise control of the servo motor 73. The addition of the height sensor 76 and the distance sensor 87 further improves the automation and accuracy of the system. At the same time, the design of the grinding wheel 810 can also be used to slightly grind the tire surface, detect the wear resistance of the tire, and find areas where the tread is poorly worn.

An opening 97 is provided at the top center of the box body 911. A vertical lead screw slide 98 is fixedly installed on the rear wall of the box body 911. An electric telescopic rod 99 along the front-to-back direction is fixedly installed at the front end of the lead screw slide 98. A smear pen 910 is fixedly provided at the front end of the electric telescopic rod 99. An identification sensor 913 is fixedly installed on the side of the smear pen 910. The bidirectional lead screw 93 is symmetrically threaded to connect two groups of cleaning mechanisms 10.

[0046] The left cleaning mechanism 10 includes: a sliding block 101, the left threaded section on the bidirectional lead screw 93 is threadedly connected to the sliding block 101, the top of the sliding block 101 is fixedly connected to a vertical rod 102, the vertical rod 102 slides upward and passes through the sliding hole 92, a horizontal motor 3 103 is fixedly installed at the front end of the middle of the vertical rod 102, the left output shaft end of the motor 3 103 is fixedly connected to a cam 104, and the left end of the vertical rod 102 located above the motor 3 103 is fixedly connected to a vertical sleeve 1 105, the sleeve 105 is slidably connected to the push rod 106 up and down, the top of the cam 104 slides and presses against the bottom of the push rod 106, the top of the push rod 106 is slidably hinged to the left end of the strip orifice plate 107, the center of the strip orifice plate 107 is rotatably connected to the vertical rod 102, the right end of the strip orifice plate 107 is hinged to the connecting rod 108, the right end of the connecting rod 108 is hinged to the cleaning brush 109, and a pair of springs 110 are symmetrically fixed between the cleaning brush 109 and the vertical rod 102.

[0047] The working principle of the above technical solution is: The design of the marking and cleaning mechanism 91 is to mark the object and clean the surface stains in combination with the detection process to improve the efficiency and accuracy of the automated processing. The specific working principle is as follows: 1. Motor 1 94 drives the bidirectional lead screw 93: After the motor 1 94 is started, its output shaft drives the bidirectional lead screw 93 to rotate. Due to the characteristics of the bidirectional lead screw 93, the threaded sections on the left and right sides thereof rotate in opposite directions, thereby driving the two cleaning mechanisms 10 (the left and right sides, but the left side is mainly described here) to move to the left and right sides respectively.

[0048] 2. Movement of the cleaning mechanism 10: The sliding block 101 in the left cleaning mechanism 10 is connected to the left thread section of the bidirectional lead screw 93 through a thread, and moves rightward (by Figure 6 The sliding block 101 drives the vertical rod 102 and all the components thereon (including the motor 3 103, the cam 104, the sleeve 105, the push rod 106, etc.) to move together.

[0049] 3. Cam mechanism drives the cleaning brush 109: When the sliding block 101 (and the vertical rod 102) moves, the motor 3 103 starts, and its left output shaft drives the cam 104 to rotate. The profile design of the cam 104 allows its top to periodically press against the bottom of the push rod 106 during the rotation process, pushing the push rod 106 to slide up and down in the sleeve 105. The up and down movement of the push rod 106 is converted into the swing of the cleaning brush 109 through the hinge connection of the strip orifice plate 107 and the connecting rod 108, thereby achieving the cleaning action on the surface of the object. At the same time, the spring 2 110 provides the necessary reset force and maintains the contact pressure between the cleaning brush 109 and the surface of the object.

[0050] Marking action: The lead screw slide 98 and the electric telescopic rod 2 99 work together to control the position of the smear pen 910. After the recognition sensor 913 detects the object to be marked, the electric telescopic rod 2 99 extends forward, so that the smear pen 910 contacts the surface of the object for marking. The lead screw slide 98 is responsible for adjusting the height of the smear pen 910 in the vertical direction to adapt to objects of different heights and mark defect positions of different heights.

[0051] Comprehensive operation: During the whole process, the rotating receiving plate 96 driven by the motor 2 95 may be used to support or rotate the object to be processed to facilitate all-round cleaning and marking. The left and right movement of the bidirectional screw 93, the swing cleaning of the cam mechanism, and the precise control of the screw slide 98 and the electric telescopic rod together complete the cleaning and marking tasks of the object.

[0052] Beneficial effects: High degree of automation: Through the integrated application of motors, lead screw slides 98, electric telescopic rods and other automation components, the automatic operation of object cleaning and marking is realized, which reduces manual intervention and improves work efficiency.

[0053] Good flexibility: The design of the bidirectional lead screw 93 enables the cleaning mechanism 10 to move left and right to adapt to the processing requirements of different positions; the combination of the lead screw slide 98 and the electric telescopic rod provides flexible adjustment in the vertical and horizontal directions, enhancing the applicability of the system.

[0054] Good cleaning effect: the cleaning brush 109 driven by the cam mechanism can effectively clean the surface of the object, and the setting of the spring 110 ensures the stable contact between the cleaning brush 109 and the surface of the object, thereby improving the cleaning quality.

[0055] Precise marking: The identification sensor 913 is used in conjunction with the electric telescopic rod and the lead screw slide 98 to accurately identify and mark the target object, thereby improving the accuracy of marking.
