The crossbeam 302 limits the rear of the parts, and the L-shaped straight plate 303 limits the sides of the parts. The inspection table 2 supports the support frame 4, and the support frame 4 supports the concave plate 5. The operator starts the servo motor 9 through the control console of cabinet 1. The output shaft of the servo motor 9 starts to rotate in both directions. The output shaft of the servo motor 9 drives the gear 10 to rotate in both directions. Under the constraint of the rack 6, the gear 10 rolls back and forth on the rack 6. The gear 10 drives the servo motor 9 to move back and forth. The output shaft of the servo motor 9 moves back and forth in the slide groove of the slot plate 7. The servo motor 9 drives the slide table 8 to move back and forth. The slide table 8 slides back and forth on the surface of the slot plate 7. The slide table 8 drives the infrared light scanner 13 to move back and forth. The slide table 8 drives the camera 14 to move back and forth. The operator starts the infrared light scanner through the control console. The system includes an infrared scanner 13 and a camera 14. The infrared scanner 13 emits infrared light to scan the surface of the component, quickly acquiring its three-dimensional coordinates. The camera 14 takes numerous photos from different angles. A three-dimensional model is reconstructed using the common feature points of the digital model acquired by the infrared scanner 13 and the photos taken by the camera 14 to detect defects on the component surface. The slide table 8 drives the slide tube 12 to move back and forth. The slide tube 12 moves back and forth on the guide rod 11.

[0025] The heat dissipation device 15 includes: a frame plate 151, which is embedded above the front of the slide table 8; a ring plate 152, which passes through and is fixed to the front of the frame plate 151; an electric fan 153, which is fixed to the inner wall of the ring plate 152; and heat dissipation fins 154, which are fixed to the back of the inside of the frame plate 151. The heat dissipation fins 154 reduce the external temperature of the infrared scanner 13 and the camera 14 through the airflow driven by the electric fan 153. While the slide table 8 moves the slide tube 12 back and forth, the slide table 8 also moves the frame plate 151 left and right.

The ring plate 152 drives the electric fan 153 to move back and forth left and right, and the ring plate 152 drives the heat sink 154 to move back and forth left and right. The operator starts the electric fan 153 with the control panel. The electric fan 153 blows airflow to the surface of the heat sink 154.

[0026] A U-shaped frame 155 is fixed to the lower front of the frame plate 151. An L-shaped plate 156 is fixed to each of the left and right sides of the U-shaped frame 155. A chamfer block 157 is fixed to the bottom surface of each of the two L-shaped plates 156. The bottom surfaces of the two chamfer blocks 157 slide in contact with the top surface of the slot plate 7. While the frame plate 151 drives the ring plate 152 to move back and forth, the frame plate 151 drives the U-shaped frame 155 to move back and forth, the U-shaped frame 155 drives the L-shaped plates 156 to move back and forth, and the L-shaped plates 156 drive the chamfer blocks 157 to move back and forth. During the back and forth movement, the chamfer blocks 157 scrape off the oil stains on the surface of the slot plate 7, thereby avoiding the problem of the equipment not moving smoothly when the defect detection table is inspecting the surface of the accessories due to the large amount of lubricating oil stains on the surface of the slot plate 7.

[0027] The air blowing device 16 includes: a vertical plate 161, fixed to the middle of the back side of the circular frame 155; a curved strip 162, fixed to the middle of the back side of the vertical plate 161; a bracket 163, fixed to the outer wall of the curved strip 162, with one end of the bracket 163 away from the curved strip 162 fixedly connected to the lower back side of the vertical plate 161; and a slot 164, fixed to the bottom surface of the curved strip 162, with a connection port in the middle of the back side of the slot 164. The slot 164 is used to guide airflow onto the surface of the accessory. The operator connects an air pump pipe to the connection port of the slot 164 and blows air onto the circular frame. While L-shaped plate 156 moves back and forth, the U-shaped frame 155 moves vertical plate 161 back and forth, vertical plate 161 moves curved plate 162 back and forth, vertical plate 161 moves bracket 163 back and forth, bracket 163 supports curved plate 162 in its back and forth movement, and curved plate 162 moves slot box 164 back and forth. During the back and forth movement of slot box 164, it blows away dust and foreign objects from the surface of the parts, thus avoiding the problem of inaccurate equipment test data caused by dust and foreign objects covering the surface of the parts when the defect detection table is inspecting the parts.

[0028] An angle bracket 165 is fixed to the back of the vertical plate 161. A connecting plate 166 is fixed to the bottom of the angle bracket 165. An arc plate 167 is fixed to the bottom of the connecting plate 166. The bottom of the arc plate 167 is fixedly connected to the top of the slide tube 12. While the vertical plate 161 drives the curved strip plate 162 to move back and forth, the vertical plate 161 drives the angle bracket 165 to move back and forth, the angle bracket 165 drives the connecting plate 166 to move back and forth, the connecting plate 166 drives the arc plate 167 to move back and forth, and the slide tube 12 supports the arc plate 167 to move back and forth, so that the vertical plate 161 supports the top of the U-shaped frame 155. This avoids the problem that the U-shaped frame 155 is not well supported when the defect detection table is inspecting the surface of the accessories due to deformation during movement.
