[0002] The main purpose of detecting surface defects of treads during the production process is to ensure product quality. Surface defect detection plays an important role in tread production: ensuring product quality and surface defects of treads will directly affect their beauty and durability. For example, surface defects such as cracks, deformation, dirt, and scratches will reduce the aesthetics and user experience of the product. Through surface defect detection, these defects can be discovered and handled in a timely manner to ensure that product quality meets standards and prevent safety accidents. Surface defects may cause problems during product use and even cause safety accidents. Currently, in order to improve production efficiency: CCD detection cameras combined with LED light sources and the principles of machine vision can be used to detect various types of metal surface defects online. By analyzing the surface defect image of the material to accurately identify the size, location, grayscale value, category, level and other information of the defect, the detection efficiency and accuracy can be greatly improved, the time and cost of manual inspection can be reduced, and the overall production efficiency can be improved.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the surface defect detection device for the production of the tread plate, the detection camera can be used to detect surface defects of the workpieces transported by the conveyor belt on the detection table. The detection position and height of the detection camera can be adjusted through the cooperation of the electric sliding table and the first electric push rod. The provided cleaning box facilitates the insertion of the detection camera into the cleaning box for dust cleaning. The hollow column can be rotated by the servo motor to drive the cleaning seat and the air blowing nozzles on the strip-shaped frame, so that the gas blown out by the air blowing nozzles can clean the dust and particles on the entire detection camera lens. The wiping piece provided on the cleaning seat can wipe the remaining dust on the lens. The provided flushing nozzle can spray cleaning agent to flush the wiping piece, and flush the dust falling on the surface clean, which is beneficial to improving the wiping effect and quality of the wiping piece on the lens;

[0018] 2. In the surface defect detection device for the production of the tread plate, the second electric push rod can be used to drive the first contact frame and the trapezoidal contact block to move. When the air blowing nozzles blow air, the trapezoidal contact block contacts the first contact rod fixed on the wave contact ring, prompting the wave contact ring to move upward and approach the cleaning seat, so as to achieve the purpose of intermittent contact between the wave contact ring and the second contact frame on the strip-shaped frame. When the air blowing nozzles are in a rotating state, they can reciprocally deflect on the strip-shaped frame, which can increase the air blowing range of the air blowing nozzles and reduce the cleaning dead angle;

[0019] The wiper blade is rotated to move upwards to clean the lens, thereby preventing water from seeping into the lens and causing the wiper blade to move downwards and contact the lens, thereby preventing water from seeping into the lens and causing the wiper blade to move downwards and contact the lens.

[0020] 3. In the surface defect inspection equipment for tread production, the dustproof plate provided at the air inlet of the inspection camera is conducive to reducing the entry of dust in the air into the inspection camera during heat dissipation. When the dust cover is connected to the dust collection device, the adsorption force generated absorbs the dust on the dustproof plate, thereby improving the heat dissipation effect of the inspection camera. The brush plate provided in the air inlet can clean the dust inside the dustproof plate during movement, thereby improving the cleaning effect.

[0021] The second interference bar on the first interference frame can interfere with the T-shaped bracket, and the dust hood can be close to the dust plate. At the same time, the third interference bar fixed on the cleaning seat can interfere with the L-shaped plate during the rotation process, prompting the dust hood to reciprocate on one side of the dust plate when working, which can reduce the adsorption dead angle. At the same time, the first interference bar moves back and forth during the movement of the dust hood, prompting the adjustment component to continuously adjust the angle of the flapping plate to flap the dust plate to shake off the dust. At the same time, the brush plate moves back and forth in the air inlet, reducing the cleaning dead angle. When the L-shaped plate moves back and forth, the third interference rod can be realized. The conflict between the first arc-shaped interference block prompts the third interference rod to move and push the working wiping piece to move horizontally, thereby improving the wiping effect.

[0040] refer to Figure 1 When the tread is inspected, it is placed on the conveyor belt 20 for transportation. The horizontal inspection position of the inspection camera 2 is adjusted by the electric slide 37 on the inspection platform 1. The first electric push rod 42 adjusts the inspection height of the inspection camera 2, so that the inspection camera 2 can detect surface defects of the product.

[0041] When the lens of detection camera 2 is covered with dust and needs to be cleaned, refer to Figures 1-6 , through the cooperation of the electric slide 37 and the first electric push rod 42, the lens of the detection camera 2 is inserted into the cleaning box 3, and a rotary joint for ventilation is installed under the hollow column 32. When the hollow column 32 rotates, the gas can flow into the air blowing nozzle 5 through the hollow column 32 and the pipeline to clean the dust and particles on the lens of the detection camera 2.

The second spring 26 continuously stores force and releases elastic force, prompting the first rotating shaft 17 to drive the blowing nozzle 5 to deflect on the bar frame 16, which can increase the blowing range of the blowing nozzle 5 and reduce the cleaning dead angle.

[0042] Meanwhile, the first C-shaped rack 30 intermittently contacts the wave contact ring 6, causing the first C-shaped rack 30 to move vertically within the cleaning seat 4. The fourth spring 31 continuously stores and releases elastic force. The first C-shaped rack 30 meshes with the arc-shaped tooth block 29 fixed on the second rotating shaft 19, thereby driving the squeezing plates 8 on both sides to deflect, continuously squeezing the wiped sheet 7 after flushing to remove excess moisture. The wiped sheet 7 reduces the amount of water stains adhering to the surface of the lens during the wiping process, preventing water from penetrating into the lens interior;

[0043] When the first contact frame 14 continues to move horizontally, refer to Figures 1-6 , the purpose of releasing the contact between the trapezoidal contact block 15 and the first contact rod 12 can be achieved. The first contact rod 12 resets. At the same time, the end of the first contact frame 14 contacts the second contact rod 33, and the twelfth spring 35 stores energy, causing the second contact rod 33 to drive the wiped sheet 7 on the sliding bracket 36 to move upward and abut against the surface of the lens.
