[0028] Please refer to Figure 1-6, A precision bearing detection device further includes a flipping component. The flipping component includes two sets of side support plates 5, which are respectively fixedly connected to the front and rear ends of the top of the bottom bracket 1. The top ends of the side support plates 5 are fixedly connected with top support plates 6.

At this time, the electric cylinder 7 retracts, raises the position of the precision bearing carrier plate 4, and then the servo motor 15 starts, driving the clamping plate 16 to flip, and the precision bearing carrier plate 4 flips synchronously, turning the other side of the workpiece upward, so that both sides can be detected in a line.

[0031] Embodiment 2: A reserved groove 23 is provided at the top end of the precision bearing carrier plate 4. An assembly and disassembly plate 19 is horizontally placed inside the reserved groove 23. A bearing snap ring 20 is fixedly connected inside the assembly and disassembly plate 19. A plurality of rubber ribbed rings 21 are adhesively bonded to the inner wall of the bearing snap ring 20. Fixing screws 22 are respectively inserted at the four corners of the top end of the assembly and disassembly plate 19. The precision bearing carrier plates 4 are arranged at equal intervals. The top end of the assembly and disassembly plate 19 is flush with the top end of the precision bearing carrier plate 4. The bottom end of the bearing snap ring 20 is flush with the bottom end of the precision bearing carrier plate 4. The outer groove 2 of the conveyor belt is not connected to the precision bearing carrier plate 4. The modular carrier plate is convenient for assembly, disassembly and replacement;

[0032] Specifically, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, the bearings are mainly placed inside the bearing snap ring 20. The rubber ribbed rings 21 inside the bearing snap ring 20 can clamp the bearings to prevent them from loosening and falling. According to the size of the bearings, the assembly and disassembly plate 19 with a bearing snap ring 20 of the corresponding specification can be selected. The assembly and disassembly plate 19 is snapped into the reserved groove 23 at the top of the precision bearing carrier plate 4, and the fixing screws 22 are driven into the corners to complete the fixation.

[0033] Embodiment 3: An air pump 26 is installed at the middle position of the top end of the top support plate 6. A air knife 28 is fixedly connected to the bottom end of the top support plate 6. An air duct 27 is installed between the rear end of the air knife 28 and the rear end of the air pump 26. The air pump 26, the air duct 27 and the air knife 28 are internally connected and communicated. The vertical center lines of the top support plate 6 and the air pump 26 coincide, which can clean the surface of the workpiece;

[0034] Specifically, as Figure 1 and Figure 6 shown, as the position of the precision bearing carrier plate 4 is raised, the air pump 26 is started synchronously. Air is continuously pumped into the air knife 28 through the air duct 27. Strong airflows are blown out from the gaps at the bottom of the air knife 28 to clean the surface of the workpiece and prevent attachments from interfering with visual inspection.

[0035] Working principle: When the utility model is in use, first, the bearing part is clamped into the precision bearing carrier plate 4. Then, the robotic arm horizontally places the precision bearing carrier plate 4 on the conveyor belt main body 3. The conveyor belt driving motor 30 drives the conveyor belt main body 3 to continuously operate, sending the precision bearing carrier plate 4 below the CCD camera module 25. The CCD camera module 25 collects the image information of the bearing and transmits it back to the background, where it is calculated and detected by the background terminal. When the precision bearing carrier plate 4 runs directly below the top support plate 6, the electric cylinder 7 pushes the sliding plate 9 downward. The limit clamp 10 and the sliding groove 8 cooperate to make the up and down displacement of the sliding plate 9 smoother. When the height of the limit pin 17 and the limit hole 18 is level, the air cylinder 11 extends, pushing the push plate 14 inward. The limit pin 17 at one end of the clamping plate 16 is inserted into the limit hole 18 at one end of the precision bearing carrier plate 4. The front and rear groups of clamping plates 16 clamp the precision bearing carrier plate 4. At this time, the electric cylinder 7 retracts, raising the position of the precision bearing carrier plate 4. As the position of the precision bearing carrier plate 4 is raised, the air pump 26 is started synchronously at this time, continuously pumping air into the air knife 28 through the air duct 27. The strong air flow is blown out from the gap at the bottom of the air knife 28, cleaning the surface of the workpiece to prevent attachments from interfering with visual inspection. Then the servo motor 15 is started, driving the clamping plate 16 to flip, and the precision bearing carrier plate 4 flips synchronously, turning the other side of the workpiece upward, so that both sides can be detected in a line. The precision bearing carrier plate 4 is used as the carrier of the bearing. The bearing is mainly placed in the bearing snap ring 20. The rubber ribbed ring 21 in the bearing snap ring 20 can clamp the bearing to prevent it from loosening and falling. According to the size of the bearing, the disassembly and assembly plate 19 with the corresponding specification bearing snap ring 20 can be selected. The disassembly and assembly plate 19 is snapped into the reserved groove 23 at the top of the precision bearing carrier plate 4, and fixing screws 22 are driven into the corners to complete the fixation, which is convenient for disassembly and replacement.
