[0023] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] The present application provides an axial diode detection device, comprising a workbench 1; a support frame 2 is fixedly mounted on the surface of the workbench 1, a lifting mechanism 3 is provided at the bottom of the support frame 2, a sliding mechanism 4 is fixedly mounted at the bottom of the lifting mechanism 3, an industrial camera 5 and a camera light source 6 are installed inside the bottom of the sliding mechanism 4, and a sorting mechanism 7 is provided on the surface of the workbench 1;

[0026] The sorting mechanism 7 includes a motor 701, a threaded rod 702, an inclined plate 703 and a limit block 704. The motor 701 is installed at an equal distance at the bottom of the workbench 1. The output end of the motor 701 is fixedly installed with a threaded rod 702. The surface of the threaded rod 702 is fixedly installed with an inclined plate 703. The limit blocks 704 are symmetrically fixedly installed on both sides of the inclined plate 703. A mounting cavity 9 is provided on the inner side of the limit block 704. A driving mechanism 10 is rotatably installed inside the mounting cavity 9. Fixed rods 8 are symmetrically provided on the surface of the workbench 1 on both sides of the sorting mechanism 7. A limiting groove 801 is provided on the inner side of the fixed rod 8. The limiting block 704 is installed inside the limiting groove 801.

[0027] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, when the device is testing the axial diodes, the personnel place multiple axial diodes on the surface of the driving mechanism 10, and then use the industrial camera 5 and the camera light source 6 to detect whether the axial diodes are damaged. If the axial diodes are good, the industrial camera 5 sends the detection data to the inside of the PLC controller 13, and the PLC controller 13 is used to turn on the motor 701 corresponding to the end where the good diodes are placed, and the output end of the motor 701 drives the threaded rod 702 to rotate, and the inclined plate 703 on the surface of the threaded rod 702 is moved up and down on the surface of the threaded rod 702, and the limit groove 801 is used to prevent the axial diodes from being damaged. The limit block 704 is fixed and limited so that the inclined plate 703 can be in an inclined state, so that the axial diodes on the surface of the driving mechanism 10 can be quickly placed into the interior of the storage box 1202, and the axial diodes are stored and placed by the storage box 1202. At the same time, through the coordinated use of the sorting mechanism 7 and the PLC controller 13, the different tilt directions of the inclined plate 703 can be adjusted, and the axial diodes can be quickly sorted to see whether they are of good quality, replacing the previous manual inspection, thereby not only saving human resources to a certain extent, but also further improving the work efficiency and convenience of the device in detecting and sorting axial diodes.

[0028] Furthermore, the lifting mechanism 3 includes a hydraulic cylinder 301 and a mounting frame 302. The hydraulic cylinder 301 is fixedly mounted on the bottom of the support frame 2. The mounting frame 302 is fixedly mounted below the hydraulic cylinder 301. The sliding mechanism 4 includes a slide 401, an electric slide rail 402, a mounting block 403 and a mounting groove 404. The slide 401 is opened at the bottom of the mounting frame 302. The electric slide rail 402 is fixedly mounted inside the slide 401. The mounting block 403 is slidably mounted on the surface of the electric slide rail 402. The surface of the mounting block 403 is provided with a mounting groove 404. The industrial camera 5 is installed inside the mounting groove 404. The camera light source 6 is fixedly mounted below the mounting block 403.

[0029] Specifically, such as Figure 1 、 Figure 2 As shown, when the device is in use, personnel can turn on the electric slide rail 402 through the PLC controller 13, and drive the industrial camera 5 and the camera light source 6 to slide on the surface of the mounting frame 302 through the mounting block 403, so that the position of the industrial camera 5 and the camera light source 6 on the surface of the workbench 1 can be quickly adjusted, and the axial diodes at different positions on the surface of the driving mechanism 10 can be detected. At the same time, personnel can turn on the PLC controller 13, turn on the hydraulic cylinder 301 through the PLC controller 13, and use the hydraulic cylinder 301 to drive the mounting frame 302 to move downward, which can facilitate the industrial camera 5 and the camera light source 6 to detect axial diodes of different sizes, thereby further improving the convenience and work efficiency of the device for axial diodes.

[0030] Furthermore, storage boxes 11 are symmetrically installed on both sides of the workbench 1, a PLC controller 13 is provided on one side of the surface of the workbench 1, a buffer mechanism 12 is provided in the inner cavity of the storage box 11, and the buffer mechanism 12 includes an electric push rod 1201, a storage box 1202, a spring 1203 and a buffer plate 1204. The electric push rod 1201 is symmetrically installed in the inner cavity of the storage box 11, and the storage box 1202 is installed on the top of the electric push rod 1201. Springs 1203 are installed at equal intervals on the surface of the storage box 1202, and a buffer plate 1204 is fixedly installed on the top of the spring 1203;

[0031] Specifically, such as Figure 1 、 Figure 2As shown, after the axial diode is inspected by the industrial camera 5, if the axial diode is of good quality, the inspection data can be sent to the inside of the PLC controller 13 through the industrial camera 5, and the PLC controller 13 is used to turn on the motor 701 corresponding to the end of the good product. The output end of the motor 701 drives the threaded rod 702 to rotate, and the inclined plate 703 on the surface of the threaded rod 702 is moved up and down on the surface of the threaded rod 702. The limiting block 704 is limited and fixed by the limiting groove 801, so that the inclined plate 703 can be in an inclined state, so that the axial diode on the surface of the driving mechanism 10 can be quickly moved. Place it into the storage box 1202. At the same time, the spring 1203 at the bottom of the buffer plate 1204 can buffer the impact force of the axial diode on the storage box 1202, thereby protecting the axial diode to a certain extent. When the storage box 1202 is full of axial diodes, the personnel can open the electric push rod 1201 through the PLC controller 13, and drive the storage box 1202 upward through the electric push rod 1201, and push the storage box 1202 out from the inside of the storage box 11, so that the personnel can remove the axial diodes after sorting by the buffer mechanism 12 inside the storage box 11 and place them.

[0032] Working principle: When inspecting axial diodes, personnel place multiple axial diodes on the surface of the driving mechanism 10, and then use the industrial camera 5 and the camera light source 6 to detect whether the axial diodes are damaged. If the axial diodes are of high quality, the industrial camera 5 will send the detection data to the inside of the PLC controller 13, and the PLC controller 13 will turn on the motor 701 corresponding to the end where the high quality diodes are placed. The output end of the motor 701 drives the threaded rod 702 to rotate, and the inclined plate 703 on the surface of the threaded rod 702 is moved up and down on the surface of the threaded rod 702. The limiting block 704 is limited and fixed by the limiting groove 801, so that the inclined plate 703 can be in an inclined state, so that the axial diodes on the surface of the driving mechanism 10 can be quickly placed into the interior of the storage box 1202, and the axial diodes are stored and placed by the storage box 1202. At the same time, through the coordinated use of the sorting mechanism 7 and the PLC controller 13, the different tilt directions of the inclined plate 703 are adjusted, so that the axial diodes can be quickly sorted to see whether they are of high quality.

[0033] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
