Step one, the conveying mechanism 12 conveys the engine soundproof and heat insulation cover located on the placement seat 13 forwards, wherein the conveying mechanism 12 belongs to the prior art known to the person skilled in the art, the servo motor 7 works to drive the gear 8 to rotate, so that the toothed ring 4, the ring cylinder 2, the annular supporting disc 3 and each turnover mechanism 5 rotate clockwise, when the turnover mechanism 5 rotates to the leftmost side, the turnover mechanism 5 extends to the upper side of the conveying mechanism 12 under the pushing action of the functional column mechanism 6 and clamps the conveyed engine soundproof and heat insulation cover, in the process, along with the clockwise rotation of the annular supporting disc 3, the driving rod assembly 53 and the clamping assembly 55, when the turnover mechanism 5 rotates to the leftmost side, the inner rod 532 and the piston disc 533 move leftwards under the pushing of the arc-shaped protruding block 62, the first spring 534 is compressed, the clamping assembly 55 is gradually pushed leftwards and extends to the upper part of the conveying mechanism 12 and is higher than the top of the placement seat 13, meanwhile, the engine soundproof and heat insulation cover is positioned on the corresponding placement seat 13 and conveyed forwards by the conveying mechanism 12, when the two clamping plates 556 are pushed to the upper part of the conveying mechanism 12 and are respectively positioned on the left side and the right side of the conveying mechanism 12, the engine soundproof and heat insulation cover is conveyed between the two clamping plates 556, the conveying mechanism 12 continues to operate, the engine soundproof and heat insulation cover is intercepted in the clamping assembly 55, meanwhile, under the action of the limiting ring 52, the two conical handles 559 are moved to the side close to each other, the two clamping plates 556 are mutually close, when the clamping assembly 55 rotates to the leftmost end, the engine soundproof and heat insulation cover is completely clamped by the two clamping plates 556, and then the turnover mechanism 5 for clamping the engine soundproof and heat insulation cover continues to revolve clockwise;
Step two, when the turnover mechanism 5 rotates away from the upper part of the conveying mechanism 12, under the action of the arc-shaped conical toothed ring 63, the turnover mechanism 5 drives the engine soundproof heat shield to rotate, meanwhile, the turnover mechanism 5 generates air flow, the air flow blows to the upper surface and the lower surface of the engine soundproof heat shield, impurities on the upper surface and the lower surface of the engine soundproof heat shield are blown away, in the process, along with the rotation of the large bevel gear 5310 under the action of the arc-shaped conical toothed ring 63, the small bevel gear 544 rotates along with the rotation of the large bevel gear 5310, the blades 543 rotate rapidly under the cooperation of an accelerator, external air is pumped in rapidly through the air inlet holes 545, wherein the accelerator belongs to the prior art known by the person skilled in the art, and finally the air is blown out evenly through the air blowing ports 5511, because each air blowing port 5511 is inclined towards the surface of the engine soundproof and heat-insulating cover, the blown air flow can directly act on the surface of the engine soundproof and heat-insulating cover to automatically purge impurities on the upper surface and the lower surface of the engine soundproof and heat-insulating cover, when the turnover mechanism 5 rotates below the visual detection assembly 10, the turnover mechanism 5 drives the engine soundproof and heat-insulating cover with clean upper surface and lower surface to continue to rotate, the visual detection assembly 10 simultaneously performs image acquisition on the upper surface and the lower surface of the engine soundproof and heat-insulating cover right below, in the process, along with the clockwise rotation of the driving rod assembly 53, when the big bevel gear 5310 is meshed with the arc-shaped bevel gear ring 63, under the action of the arc-shaped bevel gear ring 63, the big bevel gear 5310, the inner rod 532 and the clamping assembly 55 rotate, and the engine soundproof and heat-insulating cover clamped by the clamping assembly 55 rotate, the visual detection assembly 10 can collect images of the upper surface and the lower surface in real time, and transmit the collected images to the processor 9, and the processor 9 processes the images to detect whether scratches or cracks exist on the upper surface and the lower surface of the engine soundproof heat shield;
Step three, when the turnover mechanism 5 rotates to the forefront end, the turnover mechanism is not pushed by the arc-shaped protruding blocks 62, wherein the left end and the front end of the arc-shaped protruding blocks 62 are inclined, the inner rod 532 and the clamping assembly 55 are enabled to move backwards under the elastic action of the first springs 534, the clamping assembly 55 moves to the side far away from each other under the elastic action of the second springs 5512 and the cooperation of the limiting rings 52 in the backward moving process, the clamping of the engine soundproof and heat-insulating cover is released, the engine soundproof and heat-insulating cover falls onto the upper surface of the guide block 11 under the action of self gravity and slides to a designated place along the upper surface of the guide block 11, and the surface defect detection process of the engine soundproof and heat-insulating cover is finished;
And fourthly, continuing to revolve clockwise by the turnover mechanism 5, repeating the first step, the second step and the third step, and sequentially detecting surface defects of the engine soundproof and heat insulation cover conveyed forward.
