[0026] The part to be tested enters the third conveyor belt 14 in the housing 7 from the conveying component through the inlet 11. During the conveying process, the cleaning component removes attachments from the surface of the part to be tested to improve the detection accuracy. The correction component corrects the part to be tested so that the part to be tested can smoothly enter the third conveyor belt 14 from the inlet 11. The detector 13 detects the surface of the part to be tested. If the detected part has defects, the third conveyor belt 14 rotates to slide the part to be tested from the first outlet 8 to the bad part collection box (not shown in the figure). If there are no defects, the driving component drives the fourth conveyor belt 15 to rotate 180° to the third conveyor belt 14. At the top, another driving assembly drives the third conveyor belt 14 to rotate while the driving assembly drives the fourth conveyor belt 15 to reverse 180° in the same direction. Another driving assembly drives the third conveyor belt 14 to reverse 180°. At this time, the part to be tested is located on the fourth conveyor belt 15. The detector 13 detects the bottom surface of the part to be tested. If the detected part has defects, the fourth conveyor belt 15 rotates to slide the part to be tested from the second outlet 9 to the bad part collection box. If the part to be tested is detected correctly, the fourth conveyor belt 15 rotates in the opposite direction to slide the part to be tested from the third outlet 12 to the standard part collection box (not shown in the figure). The utility model can complete the detection of parts more accurately and comprehensively, greatly improving work efficiency.

[0027] Furthermore, the driving component includes a motor 18 fixed to the inner wall of the outer shell 7, a first gear 19 fixed to the output end of the motor 18, the first gear 19 is meshingly connected to the second gear 20, a transmission shaft 21 passes through the center of the second gear 20, the transmission shaft 21 is rotatably connected to the inner wall of the outer shell 7 through a bracket, third gears 22 are fixed to both ends of the transmission shaft 21, the two third gears 22 are meshingly connected to two arc-shaped tooth plates 23, one end of the arc-shaped tooth plate 23 is fixed to the side wall of the third conveyor belt 14, and the other end of the arc-shaped tooth plate 23 is in contact with the fourth conveyor belt 15.

[0028] The motor 18 drives the first gear 19 to rotate, the first gear 19 drives the second gear 20 to rotate, the second gear 20 drives the transmission shaft 21 to rotate, the transmission shaft 21 drives the two third gears 22 to rotate, the third gear 22 drives the arc-shaped tooth plate 23 to rotate, thereby realizing the flipping action of the third conveyor belt 14 and the fourth conveyor belt 15, the arc-shaped tooth plate 23 on the third conveyor belt 14 and the arc-shaped tooth plate 23 on the fourth conveyor belt 15 are staggered, and no motion interference will occur.

[0029] Furthermore, two ends of the arc-shaped tooth plate 23 are respectively fixedly connected to the limiting blocks 24 .

[0030] A limiter (not shown in the figure) is installed on the limit block 24, which can detect the position of the third gear 22 on the arc-shaped toothed plate 23. When the third gear 22 contacts the limiter, the motor 18 stops working. At the same time, the limit block 24 can prevent the arc-shaped toothed plate 23 from slipping on the third gear 22.

[0031] Furthermore, a positioner 28 is embedded on the side of the third conveyor belt 14 away from the main shaft 17 .

[0032] When the positioner 28 detects that the part to be tested moves to the middle position of the third conveyor belt 14, the third conveyor belt 14 stops rotating, so that the detector 13 can detect the part to be tested.

[0033] Furthermore, a plurality of ring sleeves 16 are rotatably sleeved on the main shaft 17 , and the third conveyor belt 14 and the fourth conveyor belt 15 are rotatably connected to the main shaft 17 via the ring sleeves 16 .

[0034] Four ring sleeves 16 are rotatably sleeved on the main shaft 17 , two of the ring sleeves 16 that are spaced apart are fixedly connected to the third conveyor belt 14 , and the other two ring sleeves 16 are fixedly connected to the fourth conveyor belt 15 .

[0035] Furthermore, the conveying component includes a second conveyor belt 4 fixedly connected to the outer shell 7, a cleaning conveyor belt 2 is installed at one end of the second conveyor belt 4 away from the outer shell 7, a first conveyor belt 1 is installed on the top of the cleaning conveyor belt 2, a cleaning component is installed on the cleaning conveyor belt 2, and a correction component is installed on the second conveyor belt 4.

[0036] The parts to be tested enter the cleaning conveyor belt 2 through the first conveyor belt 1, and arrive at the second conveyor belt 4 after being cleaned by the cleaning component. The parts to be tested are corrected by the correction component, so that the parts to be tested can enter the third conveyor belt 14 through the entrance 11 for testing.

[0038] There are flexible short hairs on the surface of the cleaning conveyor belt 2. The rotation direction of the cleaning conveyor belt 2 is opposite to that of the first conveyor belt 1. The parts to be tested can slide onto the second conveyor belt 4 by gravity. When the parts to be tested enter the cleaning conveyor belt 2, the flexible short hairs and soft hairs 27 clean the attachments on the surface of the parts to be tested. A vacuum cleaner is installed at the bottom of the cleaning conveyor belt 2. The vacuum cleaner can suck away the cleaned attachments to prevent the attachments from falling onto the second conveyor belt 4 and causing secondary contamination to the parts to be tested.

[0039] Furthermore, the correction assembly includes a pin shaft 25 fixed symmetrically to the top surface of the second conveyor belt 4, a sleeve 5 is sleeved on the outside of the pin shaft 25, a retaining spring 26 is provided between the pin shaft 25 and the sleeve 5, one end of the retaining spring 26 is fixed to the pin shaft 25, and the other end of the retaining spring 26 is fixed to the inner wall of the sleeve 5, a correction plate 6 is fixed to the outside of the sleeve 5, and the correction plate 6 is in contact with the part to be measured.

[0040] When the part to be measured moves on the second conveyor belt 4, the position of the part to be measured is corrected by the correction plate 6. When the part to be measured is large in size, the part to be measured pushes the correction plate 6 to enlarge its opening. At this time, the correction plate 6 drives the sleeve 5 to rotate around the pin shaft 25. When the part to be measured passes, the retaining spring 26 resets the correction plate 6 to facilitate the normal progress of subsequent correction work.
