[0004] As an optimization, the transmission assembly includes a slide rail fixedly installed in the middle of the top side of the frame. A slider is slidably connected inside the slide rail, and a screw is rotatably connected inside the slide rail. A hollow block is provided on the bottom side of the slider, and the screw is screwed into the inside of the hollow block. A servo motor is fixedly installed on the left side of the slide rail, and one end of the output shaft of the servo motor and one end of the screw are connected by a coupling. A storage tray is rotatably connected to the top of the hollow block, and the positioning assembly is located at the center of the storage tray.

[0005] As an optimization, the slider is in the shape of a cross.

[0006] As an optimization, the slider is equipped with a rotating motor, and the tray is fixedly installed at one end of the output shaft of the rotating motor. By starting the rotating motor, the tray can be rotated, and thus can be rotated under the industrial camera for comprehensive inspection.

[0007] As an optimization, the positioning component includes a fixed cylinder fixedly installed in the center of the storage tray. The storage tray has an array of grooves at the center that lead into the interior of the fixed cylinder. An extrusion block is slidably connected in the groove. An arc plate is fixedly installed on the top side of the extrusion block. A stud is screwed into the interior of the fixed cylinder. An extrusion head is fixedly installed at the bottom end of the stud.

[0008] As an optimization, the extrusion head is frustum-shaped, the side of the extrusion block inside the fixed cylinder is inclined, and the bottom inclined side of the extrusion head abuts against one side of the inclined side of the extrusion block.

[0009] As an optimization, a guide rod is inserted into the inside of the extrusion block, and a spring is fixedly installed between the extrusion block and one side of the inner wall of the chute, with the spring sleeved on the outside of the guide rod.

[0010] The beneficial effects of this utility model are:

[0011] This electric vehicle wheel hub end cover appearance inspection device uses a servo motor to drive a screw to rotate inside a hollow block, which in turn causes a tray to slide back and forth. This facilitates moving the wheel hub placed on top of the tray to the area under the industrial camera for inspection. Simultaneously, the motor drives the tray to rotate, enabling comprehensive inspection of the wheel hub, thus eliminating the need for manual visual inspection and improving inspection efficiency and accuracy.

[0012] This electric vehicle wheel hub end cover appearance inspection device rotates inside the fixed cylinder by turning the stud, which drives the extrusion head to press the extrusion block to one side inside the fixed cylinder. This causes the extrusion block to be squeezed out, which in turn causes the surrounding arc plates to move outward and spread outward. This causes the plates to press against the inner wall of the wheel hub and position it, thus positioning the wheel hub in the center of the tray, which facilitates the centering of the wheel hub.

Detailed Implementation

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 An electric vehicle wheel hub end cover appearance inspection device includes a frame 1, a support rod 2 fixedly installed on the top side of the frame 1, a top cover fixedly installed on the top of the support rod 2, a controller 3 set on the top of the top cover, a transparent window 4 installed between the bottom frames of the support rod 2, a transmission component 5 for reciprocating transmission of the wheel hub set in the middle of the top side of the frame 1, a positioning component 6 for positioning the wheel hub set on the top of the transmission component 5, an industrial camera 7 cooperating with an image processing system set in the center of the bottom side of the top cover, and a lighting lamp 8 set on the bottom side of the top cover and around the industrial camera 7.

[0021] Please see Figure 3 The transmission component 5 includes a slide rail 9 fixedly installed in the middle of the top side of the frame 1. A slider 10 is slidably connected inside the slide rail 9, and a screw 11 is rotatably connected inside the slide rail 9. A hollow block 12 is provided on the bottom side of the slider 10, and the screw 11 is screwed into the hollow block 12. A servo motor 13 is fixedly installed on the left side of the slide rail 9, and one end of the output shaft of the servo motor 13 is connected to one end of the screw 11 through a coupling. A storage tray 14 is rotatably connected to the top of the hollow block 12, and the positioning component 6 is located at the center of the storage tray 14. By starting the servo motor 13, the screw 11 can be driven to rotate inside the hollow block 12, which will drive the slider 10 to slide inside the slide rail 9, thereby driving the hub placed on the top of the storage tray 14 to be located below the industrial camera 7 for detection.

[0022] Please see Figure 3 The slider 10 is in the shape of a cross. A rotating motor is installed inside the slider 10, and the tray 14 is fixedly installed at one end of the output shaft of the rotating motor. By starting the rotating motor, the tray 14 can be rotated, and thus can be rotated under the industrial camera 7 for comprehensive inspection.

[0023] Please see Figure 4 The positioning component 6 includes a fixed cylinder 15 fixedly installed in the center of the storage tray 14. The storage tray 14 has a groove array at the center that leads into the interior of the fixed cylinder 15. An extrusion block 16 is slidably connected in the groove. An arc plate 17 is fixedly installed on the top side of the extrusion block 16. A stud 18 is screwed into the interior of the fixed cylinder 15. An extrusion head 19 is fixedly installed at the bottom end of the stud 18. The extrusion head 19 is frustum-shaped. One side of the extrusion block 16 inside the fixed cylinder 15 is inclined. The bottom inclined side of the extrusion head 19 abuts against one side of the inclined side of the extrusion block 16. By turning the stud 18 inside the fixed cylinder 15, the extrusion head 19 can be driven to press down on one side of the extrusion block 16 inside the fixed cylinder 15, thereby squeezing out the extrusion block 16. This will cause the arc plates 17 around the perimeter to move outward in a diffused manner, thereby pressing against the inner wall of the hub to position it and keeping the hub at the center of the storage tray 14.

[0024] Please see Figure 3 A guide rod 20 is inserted inside the extrusion block 16. A spring 21 is fixedly installed between the extrusion block 16 and one side of the inner wall of the slide groove. The spring 21 is sleeved on the outside of the guide rod 20. When the extrusion block 16 slides, it will compress the spring 21. After the wheel hub is removed after the inspection is completed, the spring 21 can drive the extrusion block 16 to reset, which is convenient for the next set of wheel hubs to be inspected.

[0025] In use, the servo motor 13 is first started to drive the screw 11 to rotate inside the hollow block 12, which in turn drives the slider 10 to slide along the inner wall of the slide rail 9, thereby moving the tray 14 out. At this time, the hub can be placed on the tray 14, and the center of the hub is fitted onto the outside of the fixed cylinder 15. Then, by turning the stud 18 inside the fixed cylinder 15, the extrusion head 19 is driven to press the extrusion block 16 on one side inside the fixed cylinder 15, thus extruding the extrusion block 16. This causes the surrounding arc plates 17 to move outward in a diffused manner, thus pressing against the inner wall of the hub to position it, and making the hub located at the center of the tray 14. Similarly, by driving the screw 11 to rotate in the opposite direction through the servo motor 13, the slider 10 can move the tray 14 to below the industrial camera 7. At the same time, the illumination is provided by the lighting lamp 8, making the shooting and detection clearer. At this time, the industrial camera 7 can take pictures, and the captured content will be uploaded to the image processing system for analysis. Finally, the detection result can be obtained and the detection is completed.

[0026] In summary, the electric vehicle wheel hub end cover appearance inspection device, by starting the servo motor 13, drives the screw 11 to rotate inside the hollow block 12, which in turn drives the storage tray 14 to slide back and forth. This facilitates moving the wheel hub placed on top of the storage tray 14 to below the industrial camera 7 for inspection. At the same time, the motor drives the storage tray 14 to rotate, thereby enabling a comprehensive inspection of the wheel hub, which can be replaced by manual visual inspection, improving inspection efficiency and accuracy.

[0027] By turning the stud 18 inside the fixed cylinder 15, the extrusion head 19 can be driven to press the extrusion block 16 downward to one side inside the fixed cylinder 15, thus extruding the extrusion block 16. This causes the surrounding arc plates 17 to move outward simultaneously, thus pressing against the inner wall of the hub to position it, and making the hub located at the center of the tray 14, which facilitates the centering of the hub.
