[0048] Through the above - mentioned technical solution, stable support is provided by the support legs 101, and the conveyor belt 102 realizes the continuous conveying of the workpiece bearing 6, providing a stable workpiece source for the subsequent detection process;

[0049] The first driving motor 204 drives the first connecting shaft rod 205 to rotate, enabling the first industrial camera 206 to perform all-round coverage detection on the inner ring wall of the workpiece bearing 6. The second industrial camera 209 cooperates with the first industrial camera 206 to simultaneously detect the outer ring wall of the workpiece bearing 6, achieving synchronous detection of the inner and outer ring walls and improving the detection efficiency.

[0050] The second hydraulic cylinder 302 and the third hydraulic cylinder 304 cooperate to achieve precise movement and positioning of the workpiece bearing 6 in space, facilitating accurate clamping and turning operations of the workpiece bearing 6. Through the cooperation of the second driving motor 306 and the clamping member, the turning action of the workpiece bearing 6 can be achieved, ensuring that both ends of the workpiece bearing 6 can be detected and eliminating detection blind spots.

[0051] The laser sensor 401 can accurately detect the position of the workpiece bearing 6, providing precise positioning for visual inspection.

[0053] The PLC controller is used to uniformly control each mechanism, which can accurately coordinate the operation of each mechanism and ensure the efficient and stable progress of the entire detection process.

[0054] See Figures 4 to 5 As shown, the clamping member includes a mounting plate 307 fixedly installed on the output shaft of the second driving motor 306. An installation cavity 3071 is provided on one side of the mounting plate 307. Support bearings 3072 are respectively fixedly installed at both ends inside the installation cavity 3071. A left-right hand screw rod 3073 is fixedly installed between the inner rings of the two support bearings 3072. Threaded sleeves 3074 are respectively threadedly connected to the left and right hand screw ends of the left-right hand screw rod 3073. A clamping jaw 308 is fixedly connected to the threaded sleeve 3074. The workpiece bearing 6 is clamped between the two clamping jaws 308. One end of the mounting plate 307 is fixedly installed with a third driving motor 3075, and the output shaft of the third driving motor 3075 is fixedly connected to one end of the left-right hand screw rod 3073; the third driving motor 3075 is electrically connected to the PLC controller.

[0055] The third driving motor 3075 drives the left-right hand screw rod 3073 to rotate, causing the two threaded sleeves 3074 to drive the clamping jaws 308 to move towards or away from each other, thereby realizing the adaptive clamping of the workpiece bearing 6. The support bearings 3072 ensure the smooth rotation of the left-right hand screw rod 3073, making the clamping jaws 308 more stable and reliable during the clamping process, and avoiding affecting the turning operation and detection accuracy of the bearing due to unstable clamping.

[0056] SeeFigure 1 , 2 As shown in FIG. 6, the pusher includes a second support plate 402 fixedly installed on the support leg 101. A fourth hydraulic cylinder 403 is fixedly installed on the top of the second support plate 402. A push plate 404 is fixedly connected to the telescopic end of the fourth hydraulic cylinder 403. The push plate 404 contacts the defective product of the workpiece bearing 6. The fourth hydraulic cylinder 403 is electrically connected to the PLC controller.

[0057] The fourth hydraulic cylinder 403 can precisely control the extension and retraction actions of the push plate 404, and can accurately push the defective workpiece bearing 6 off the conveyor belt, realizing the effective separation of defective products and good products, and improving the accuracy of sorting.

[0058] See Figure 1 , 2 As shown in FIG., two positioning lines 103 are provided on the surface of the conveyor belt 102. The workpiece bearing 6 is placed between the two positioning lines 103.

[0059] The positioning line 103 can quickly limit the position of the workpiece bearing 6 on the conveyor belt, facilitating the visual inspection mechanism to accurately detect it, and improving the detection accuracy and consistency.

[0060] See Figures 1 - 3 As shown in FIG., the first industrial camera 206 extends into the inner ring of the workpiece bearing 6 and covers the entire inner ring wall of the workpiece bearing 6 through cooperation with the first drive motor 204; the second industrial camera 209 is located at the upper outer side of the workpiece bearing 6, and the detection end of the second industrial camera 209 looks down at the outer top wall and outer side wall of the workpiece bearing 6 at an angle of 30 - 60°.

[0061] The first industrial camera 206 extends into the inner ring of the workpiece bearing 6 and rotates in cooperation with the first drive motor 204, capable of covering the entire inner ring wall for detection, and can comprehensively and carefully discover defects on the inner ring wall, improving the accuracy and integrity of inner ring detection; the second industrial camera 209 looks down at the outer top wall and outer side wall of the bearing at an angle of 30 - 60°, preferably 45°, and can obtain image information of the outer ring wall from a specific angle. Compared with simple vertical or horizontal detection, it can detect defects at more angles and improve the comprehensiveness of outer ring detection.

[0062] See Figures 4 to 5 As shown in FIG., a first rubber pad 3081 is fixedly installed on the clamping surface of the jaw 308, and anti-slip ridges are provided on the surface of the first rubber pad 3081.

[0063] The first rubber pad 3081 can prevent the clamping jaws 308 from damaging the surface of the workpiece bearing 6 during the process of clamping the workpiece bearing 6, protecting the surface quality of the workpiece bearing 6. In addition, the anti-slip ridges increase the friction force between the clamping jaws 308 and the workpiece bearing 6, enabling the clamping jaws 308 to clamp the workpiece bearing 6 more firmly, preventing the workpiece bearing 6 from sliding or falling off during operations such as turning over, and ensuring the stability and accuracy of the operation.

[0064] See Figure 4 As shown, a chute 3011 is formed at the top of the first support plate 301. A slider 3012 is slidably installed inside the chute 3011. An expansion rod 309 is connected to the slider 3012. The expansion rod 309 includes an outer rod and an inner rod that is movably inserted into one end of the outer rod. The outer rod is fixedly connected to the slider 3012, and the inner rod is fixedly connected to the second connecting block 305. The cooperation of the chute 3011 and the slider 3012 provides a guiding function for the second connecting block 305 and the components connected thereto, making the components move more smoothly during the movement process.

[0065] See Figure 6 As shown, a second rubber pad 405 is fixedly installed on the pushing surface of the pushing plate 404. During the material pushing process, the second rubber pad 405 can play a certain buffering role, making the contact between the pushing plate 404 and the workpiece bearing 6 softer, avoiding damage or displacement deviation of the workpiece bearing 6 caused by too rigid pushing actions, and ensuring the smooth progress of the sorting operation.

[0066] See Figures 4 to 5 As shown, a buffer mesh 502 is fixedly installed on the inner wall of the aggregate bin 501. The buffer mesh 502 extends at an inclined angle to the discharge port of the workpiece bearing 6. The inclined buffer mesh 502 can play a buffering role for the falling workpiece bearing 6, reducing the impact force of the collision between the workpiece bearing 6 and the inner wall of the aggregate bin 501, preventing the workpiece bearing 6 from being damaged due to collision, and protecting the quality of the workpiece bearing 6.

[0067] When the present invention is in use, the workpiece bearing 6 is placed on the conveyor belt 102 of the feeding mechanism 1. The positioning line 103 on the surface of the conveyor belt 102 plays a role in quickly positioning the bearing. The conveyor belt 102 operates under the control of the control mechanism 7 to convey the workpiece bearing 6 towards the visual inspection part.

[0068] When the workpiece bearing 6 reaches the visual inspection position, the laser sensor 401 in the positioning and conveying mechanism 4 detects that the workpiece bearing 6 is in place and feeds back a signal to the control mechanism 7. The control mechanism 7 controls the conveyor belt 102 to stop conveying, and starts the first hydraulic cylinder 202 to adjust the heights of the first industrial camera 206 and the second industrial camera 209 according to the bearing specifications. The first drive motor 204 drives the first connecting shaft rod 205 and the first industrial camera 206 to rotate. The first industrial camera 206 extends into the inner ring of the workpiece bearing 6 and covers the entire inner ring wall for inspection. The second industrial camera 209 looks down at the outer top wall and the outer side wall of the workpiece bearing 6 at an angle of 30 - 60°. The two cameras simultaneously inspect the inner and outer ring walls of the workpiece bearing 6, and transmit the collected image information to the control mechanism 7 for analysis and processing to determine whether there are defects in the bearing.

[0069] If it is necessary to inspect the other end of the workpiece bearing 6, the control mechanism 7 controls the flipping mechanism 3 to start. The second hydraulic cylinder 302 and the third hydraulic cylinder 304 act in coordination to move the second drive motor 306 and the clamping member to a suitable position. The third drive motor 3075 drives the left - right screw rod 3073 to rotate, causing the jaws 308 to open, clamping the workpiece bearing 6. Then the second drive motor 306 drives the workpiece bearing 6 to flip 180°, completing the flipping operation for inspecting the other end of the bearing. During the flipping process, the chute 3011, the slider 3012, and the telescopic rod 309 play a guiding and buffering role to ensure smooth movement.

[0070] After the visual inspection is completed, the conveyor belt 102 conveys the workpiece bearing 6 to be inspected behind forward, and the inspected workpiece bearing 6 is moved in front of the pusher. The control mechanism 7 controls the pusher in the positioning and conveying mechanism 4 to act according to the inspection result. If it is a defective product, the control mechanism 7 controls the fourth hydraulic cylinder 403 to extend, and the push plate 404 pushes the defective workpiece bearing 6 off the conveyor belt 102, causing it to fall into the collection box 501 located opposite the pusher. If it is a non - defective product, the workpiece bearing 6 continues to move on the conveyor belt and falls into the collection box 501 at the discharge port at the end of the conveyor belt 102. The second rubber pad 405 on the push plate 404 can prevent damage to the workpiece bearing 6 during the pushing process.

[0071] The two collection boxes 501 respectively collect defective and non - defective workpiece bearings 6. The buffer net 502 on the inner wall of the collection box 501 plays a buffering role for the falling workpiece bearings 6, preventing the workpiece bearings 6 from being damaged by collision, and at the same time guiding the workpiece bearings 6 to slide smoothly to the bottom of the collection box 501 to complete the material collection process.

[0072] Under the unified coordination of the control mechanism 7, each mechanism closely cooperates in the entire work process, realizing the full - automatic inspection operation of new - energy vehicle bearings from conveying, inspection, flipping to sorting and material collection.

[0073] The basic principle of the present invention has been shown and described above. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The descriptions in the above embodiments and the specification only illustrate the principle of the present invention.
