[0021] Step 1: The transmission mechanism transmits the engine sound insulation and heat insulation cover on the placement seat forward, and the servo motor drives the gear to rotate, thereby causing the gear ring, the ring cylinder, the annular support plate and each flip mechanism to rotate clockwise. When the flip mechanism rotates to the leftmost side, the flip mechanism is pushed by the functional column mechanism to extend to the top of the transmission mechanism and clamp the transmitted engine sound insulation and heat insulation cover. After that, the flip mechanism clamping the engine sound insulation and heat insulation cover continues to revolve clockwise;

[0022] Step 2, after the flipping mechanism rotates away from the top of the transmission mechanism, under the action of the functional column mechanism, the flipping mechanism drives the engine sound insulation and heat insulation cover to rotate, and at the same time, the flipping mechanism generates airflow to blow to the upper and lower surfaces of the engine sound insulation and heat insulation cover to blow away the impurities on the upper and lower surfaces of the engine sound insulation and heat insulation cover. When the flipping mechanism rotates to the bottom of the visual detection component, the flipping mechanism drives the engine sound insulation and heat insulation cover to continue to rotate, and at the same time, the visual detection component collects images of the upper and lower surfaces of the engine sound insulation and heat insulation cover directly below, and transmits the collected images to the processor, which processes the images to detect whether there are scratches or cracks on the upper and lower surfaces of the engine sound insulation and heat insulation cover;

[0023] Step 3: When the flip mechanism rotates to the front end, it is not pushed by the functional column mechanism, and the flip mechanism returns to its original state, releasing the clamping of the engine sound insulation and heat insulation cover. The engine sound insulation and heat insulation cover falls to the upper surface of the guide block under the action of its own gravity, and slides along the upper surface of the guide block to the designated location. At this point, the surface defect detection process of an engine sound insulation and heat insulation cover is completed;

[0024] Step 4: The flipping mechanism continues to revolve clockwise, and the above steps 1, 2 and 3 are repeated to inspect the surface defects of the engine sound insulation and heat insulation cover that is subsequently transmitted forward.

[0025] Beneficial Effects

[0027] 1. A device and method for detecting surface defects of an engine sound insulation and heat insulation cover. Through the cooperation between an annular support plate, a gear ring, a flipping mechanism, a functional column mechanism, gears, a visual inspection component and a transmission mechanism, under the action of the functional column mechanism, the flipping mechanism can automatically clamp the engine sound insulation and heat insulation cover transmitted from the transmission mechanism during the revolution, and then drive the engine sound insulation and heat insulation cover to rotate while revolving. During the rotation, airflow is generated in the flipping mechanism to clean the upper and lower surfaces of the engine sound insulation and heat insulation cover in advance to prevent impurities from adhering to its surface. Then the visual inspection component collects images of the upper and lower surfaces of the engine sound insulation and heat insulation cover with a clean surface to ensure the accuracy of defect detection. The flipping mechanism continues to revolve, and when it is not affected by the functional column mechanism, it can automatically loosen the clamping of the engine sound insulation and heat insulation cover, thereby realizing continuous and automated surface defect detection operations on multiple engine sound insulation and heat insulation covers.

[0028] 2. A device and method for detecting surface defects of an engine sound insulation and heat insulation cover. Through the mutual cooperation among the annular support plate, the vertical plate, the limit ring, the drive rod assembly, the clamping assembly and the arc-shaped protrusion, as the annular support plate, the drive rod assembly and the clamping assembly rotate clockwise, when the flip mechanism rotates to the leftmost end, the inner rod moves to the left under the push of the arc-shaped protrusion, and the clamping assembly is pushed to the left. At the same time, under the action of the limit ring, the two conical handles move toward each other, and the two clamps approach each other, so that the engine sound insulation and heat insulation cover transmitted forward can be gradually clamped, ensuring the continuity and efficiency of the operation.

[0029] 3. A device and method for detecting surface defects of an engine sound insulation and heat insulation cover. Through the cooperation between the inner rod, the large bevel gear and the arc-shaped bevel gear ring, as the drive rod assembly rotates clockwise, when the large bevel gear engages with the arc-shaped bevel gear ring, the arc-shaped bevel gear ring can cause the large bevel gear, the inner rod and the clamping assembly to rotate, thereby causing the engine sound insulation and heat insulation cover clamped by the clamping assembly to rotate. During the rotation of the engine sound insulation and heat insulation cover, its upper and lower surfaces can be fully displayed, and the visual inspection component can perform real-time image acquisition of its upper and lower surfaces to improve the efficiency of inspection.

[0030] 4. A device and method for detecting defects on the surface of an engine sound insulation and heat insulation cover. Through the cooperation between blades, small bevel gears, air inlets, exhaust holes, hollow discs and air cavities, as the large bevel gear rotates under the action of the arc-shaped bevel gear ring, the small bevel gear also rotates. With the cooperation of an accelerator, the blades rotate rapidly, and the external gas is quickly sucked in through the air inlet. The gas passes through the exhaust hole, the telescopic hose, the air inlet, the air cavity and the air guide cavity, and is finally blown out evenly through each blowing port. Since each blowing port is inclined toward the surface of the engine sound insulation and heat insulation cover, the blown airflow can directly act on the surface of the engine sound insulation and heat insulation cover, automatically blow away impurities on the upper and lower surfaces, and improve the accuracy and reliability of image acquisition.

[0031] 5. A device and method for detecting surface defects of an engine sound insulation and heat insulation cover. Through the cooperation between a support plate, a limit rod, a clamping plate and a threaded rod, the threaded rod is screwed, and the marking line on the surface of the threaded rod is observed at the same time. The initial spacing between the two clamping plates is adjusted so that the clamping assembly can clamp the engine sound insulation and heat insulation cover of the corresponding size. By changing the initial spacing between the two clamping plates, the clamping assembly can clamp the engine sound insulation and heat insulation covers of different sizes, and has a wide range of applications.

[0057] Step 1, the transmission mechanism 12 transmits the engine sound insulation and heat insulation cover located on the placement seat 13 forward, wherein the transmission mechanism 12 belongs to the prior art known to those skilled in the art, the servo motor 7 works to drive the gear 8 to rotate, and then the gear ring 4, the ring tube 2, the annular support plate 3 and each flip mechanism 5 rotate clockwise, when the flip mechanism 5 rotates to the leftmost side, under the push of the functional column mechanism 6, the flip mechanism 5 extends to the top of the transmission mechanism 12, and clamps the transmitted engine sound insulation and heat insulation cover, during the process, with the clockwise rotation of the annular support plate 3, the driving rod assembly 53 and the clamping assembly 55, when the flip mechanism 5 rotates to the leftmost end, under the push of the arc-shaped protrusion 62, the inner rod 532 and the piston plate 533 move to the left, the first spring 534 is compressed, and the clamping assembly 5 5 is gradually pushed to the left, extending to the top of the conveying mechanism 12 and higher than the top of the placement seat 13. At the same time, the engine sound insulation and heat insulation cover is located on the corresponding placement seat 13 and is transported forward by the conveying mechanism 12. When the two clamping plates 556 are pushed to the top of the conveying mechanism 12 and are respectively located on the left and right sides of the conveying mechanism 12, the engine sound insulation and heat insulation cover is transported between the two clamping plates 556. The conveying mechanism 12 continues to operate, and the engine sound insulation and heat insulation cover is intercepted in the clamping assembly 55. At the same time, under the action of the limit ring 52, the two conical handles 559 move to the side close to each other, and the two clamping plates 556 approach each other accordingly. When the clamping assembly 55 rotates to the leftmost end, the engine sound insulation and heat insulation cover is completely clamped by the two clamping plates 556, and then the flipping mechanism 5 clamping the engine sound insulation and heat insulation cover continues to revolve clockwise;

[0058] Step 2, after the flipping mechanism 5 turns away from the top of the transmission mechanism 12, under the action of the arc-shaped bevel gear ring 63, the flipping mechanism 5 drives the engine sound insulation and heat insulation cover to rotate, and at the same time, the flipping mechanism 5 generates airflow, which blows to the upper and lower surfaces of the engine sound insulation and heat insulation cover to blow away the impurities on the upper and lower surfaces of the engine sound insulation and heat insulation cover. In the process, as the large bevel gear 5310 rotates under the action of the arc-shaped bevel gear ring 63, the small bevel gear 544 also rotates accordingly, and with the cooperation of the accelerator, the blade 543 rotates rapidly, and the external gas is quickly sucked in through the air inlet 545, wherein the accelerator belongs to the prior art well known to those skilled in the art, and the gas passes through the exhaust hole 546, the telescopic hose 539, the air inlet 536, the air cavity 535 and the air guide cavity 5510, and is finally evenly blown out through each blowing port 5511. Since each blowing port 5511 is inclined toward the surface of the engine sound insulation and heat insulation cover, the blown airflow can directly act on the engine sound insulation and heat insulation cover. The surface of the heat shield is automatically swept away with impurities on its upper and lower surfaces. When the flip mechanism 5 rotates to the bottom of the visual detection component 10, the flip mechanism 5 drives the engine sound insulation and heat insulation shield with clean upper and lower surfaces to continue to rotate. At the same time, the visual detection component 10 collects images of the upper and lower surfaces of the engine sound insulation and heat insulation shield directly below. During the process, as the driving rod assembly 53 rotates clockwise, when the large 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 large bevel gear 5310, the inner rod 532 and the clamping assembly 55 are rotated, and then the engine sound insulation and heat insulation shield clamped by the clamping assembly 55 is rotated. During the rotation of the engine sound insulation and heat insulation shield, the visual detection component 10 can collect real-time images of its upper and lower surfaces, and transmit the collected images to the processor 9. The processor 9 processes the images to detect whether there are scratches or cracks on the upper and lower surfaces of the engine sound insulation and heat insulation shield.

[0059] Step 3, when the flip mechanism 5 rotates to the front end, it is not pushed by the arc-shaped protrusion 62, wherein the left end and the front end of the arc-shaped protrusion 62 are both inclined, and under the elastic action of the first spring 534, the inner rod 532 and the clamping assembly 55 move backwards, and in the process of the clamping assembly 55 moving backwards, under the elastic action of the second spring 5512 and the cooperation of the limit ring 52, the two clamping plates 556 move to the side away from each other, and the clamping of the engine sound insulation and heat insulation cover is released. The engine sound insulation and heat insulation cover falls to the upper surface of the guide block 11 under the action of its own gravity, and slides to the designated location along the upper surface of the guide block 11, and the surface defect detection process of an engine sound insulation and heat insulation cover is completed;

[0060] Step 4: The flipping mechanism 5 continues to revolve clockwise, and the above steps 1, 2 and 3 are repeated to detect surface defects of the engine sound insulation and heat insulation cover that is subsequently transmitted forward.
