[0036] The end of two telescopic rods 11 protruding outside carrier 8 is fixedly connected with gear 10 that can drive telescopic rod 11 to rotate, the surface of installation disc 3 is provided with four blanking grooves 14 arranged in circle equidistant, blanking groove 14 is located directly below carrier 8, to provide space for blanking of workpiece.

[0037] The inside of the detection machine body 1 is fixedly connected with support columns 17 arranged at equal intervals in a circle to support the fixed plate 7. The upper end of the support column 17 is fixedly connected with the fixed plate 7 to provide installation space for the subsequent structure. The output end of the servo motor 4 is rotatably connected with the inside of the fixed plate 7 through the surface of the fixed plate 7. The surface of the fixed plate 7 is also provided with a blanking groove 14 to provide blanking space for the workpiece. The blanking groove 14 on the fixed plate 7 corresponds to one blanking groove 14 on the mounting disc 3.

[0038] The inside of the detection machine body 1 is fixedly connected with a support 5 for supporting the visual detection camera 6. The support 5 is provided with a visual detection camera 6 for visually detecting the workpiece. The visual detection camera 6 is located directly above a carrier 8, so that the visual detection camera 6 can smoothly detect the workpiece in the carrier 8. The inside of the detection machine body 1 is fixedly installed with a first electric push rod 15 for providing power for the operation of the device. The output end of the first electric push rod 15 is fixedly connected with a moving frame 16 for providing installation space for two racks 20. The surface of the moving frame 16 is fixedly connected with two racks 20 for driving the telescopic rods 11 to rotate. The surface of the rack 20 is meshingly connected with the surface of the gear 10.

[0039] The first electric push rod 15 is electrically connected with the visual detection camera 6, so that the first electric push rod 15 can be automatically started when the visual detection camera 6 detects the workpiece, thereby driving the rack 20 to drive the gear 10, so that the workpiece rotates, and the visual detection camera 6 can detect the workpiece in a wide range, improving the detection quality of the device for the workpiece.

[0040] The inside of the detection machine body 1 is fixedly installed with a discharge rail 2 for guiding the discharge of the workpiece. The discharge rail 2 is inclined, and the upper end of the discharge rail 2 is located in the blanking groove 14 on the fixed plate 7, so that the discharge rail 2 can receive the falling workpiece.

[0041] The inside of the detection machine body 1 is fixedly installed with a second electric push rod 18 for providing power for the discharge of the workpiece. The output end of the second electric push rod 18 is fixedly connected with a lifting frame 19 for providing installation space for two second magnets 21. The two sides of the lifting frame 19 are fixedly connected with U-shaped second magnets 21, so that the U-shaped second magnets 21 do not block the telescopic rods 11 when rising, avoiding movement interference and ensuring smooth operation of the device.

[0042] The second magnet 21 is attracted to the first magnet 12, and the side of the second magnet 21 close to the first magnet 12 is fixedly connected with a buffer pad 22 for buffering the impact force between the second magnet 21 and the first magnet 12, so that when the second magnet 21 is adsorbed to the first magnet 12, the collision between the first magnet 12 and the second magnet 21 can be effectively reduced, and the first magnet 12 and the second magnet 21 are prevented from being damaged, thereby prolonging the service life of the device.

[0043] The second electric push rod 18 is electrically connected with the visual detection camera 6, so as to receive the signal transmitted by the moving frame 16 to determine whether the second electric push rod 18 is started or not.

[0044] The power supply, wire, controller and microcomputer matched with the servo motor 4, the first electric push rod 15 and the second electric push rod 18 are not described in detail because they are not main structures.

[0045] The working principle of the machine vision automatic detection product device using the carrier of the embodiment is as follows: when the workpiece is detected, the worker pushes the two clamping plates 13 to move away from each other, so that the two telescopic rods 11 are retracted and the non-magnetic spring 9 is compressed, and then the workpiece is placed between the two clamping plates 13, and then the clamping plates 13 are not pushed again, so that the two clamping plates 13 are reset under the elastic force of the non-magnetic spring 9. Since the workpiece blocks the movement of the two clamping plates 13, the clamping plates 13 can clamp and fix the workpiece under the elastic force of the non-magnetic spring 9.

[0046] Then, the worker can start the servo motor 4 through the controller, so that the servo motor 4 drives the mounting disc 3 to rotate by 90 degrees, and then places the workpiece in another carrier 8. Then, the servo motor 4 is started again, so that the carrier 8 on which the workpiece is installed moves to the lower side of the visual detection camera 6. At this time, the visual detection camera 6 detects the presence of the workpiece, and then transmits a signal to the first electric push rod 15, so that the first electric push rod 15 is started to drive the moving frame 16 to move, thereby driving the rack 20 to move, so that the rack 20 is engaged with the gear 10, thereby driving the telescopic rod 11 to rotate, thereby driving the clamping plate 13 to rotate, thereby rotating the workpiece in the carrier 8, thereby expanding the detection area of the visual detection camera 6 on the workpiece, and improving the detection quality of the equipment on the workpiece.

[0047] Subsequently, the visual inspection camera 6 transmits the detection result to the microcomputer, and the microcomputer transmits a signal to the controller of the second electric push rod 18. Subsequently, under the re-activation of the servo motor 4, the workpiece is moved to the directly above the second electric push rod 18. If the workpiece is a good product, the second electric push rod 18 is normally activated, thereby driving the lifting frame 19 and the second magnet 21 to rise, and further enabling the second magnet 21 to correspond to the first magnet 12. At this time, under the magnetic force of the second magnet 21 and the first magnet 12, the first magnet 12 approaches the second magnet 21, thereby enabling the two clamping plates 13 to move in opposite directions, and further enabling the clamping plates 13 to no longer clamp the workpiece. At this time, the workpiece falls on the discharge track 2 and slides out of the device along the discharge track 2. If the workpiece is a defective product, the second electric push rod 18 is not activated, thereby enabling the workpiece to be moved in front of the operator again under the re-activation of the servo motor 4. The operator can take out the defective product and replace it with a workpiece to be detected.

[0048] The above is only an optional embodiment of the present disclosure and is not used to limit the present disclosure. The present disclosure can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
