A pin surface defect video detection and sorting device

Abstract

This utility model discloses a video detection and sorting device for ejector pin surface defects. The device includes a shelf with multiple linearly arranged grooves on its upper surface. Two handles are fixedly connected to the upper surface of the shelf, and sliding grooves are formed on opposite sides of each handle. A second threaded rod is rotatably connected inside each handle. This utility model utilizes two rotating blocks to drive the two second threaded rods to rotate. The two threaded rods are threadedly driven to both ends of a limiting plate, causing the limiting plate to move within the sliding grooves and grooves. By observing the scales on two graduated bars, the device moves both ends of the limiting plate to the required limiting position for the ejector pin to be detected. Then, the end of the ejector pin to be detected (the end that does not need to be detected) is tightly fitted against the surface of the limiting plate, ensuring that the protruding length of the ejector pin meets the detection requirements, thus achieving rapid ejector pin placement and improving detection efficiency.

Description

Technical Field

[0001] This utility model relates to a video detection and sorting device, specifically a video detection and sorting device for surface defects of ejector pins. Background Technology

[0002] As a core component in the fields of machining and mold manufacturing, the technological development of ejector pins has always revolved around improving precision, wear resistance and automation adaptability. During the production of ejector pins, it is necessary to detect defects on the surface of the ejector pins to ensure that the ejector pins can be used normally.

[0003] Publication No. CN220304671U discloses a video detection and sorting device and method for pin surface defects. However, in the implementation of this scheme, the cleaned pins are placed manually in the V-groove on the support platform and the support platform is fixed on the conveyor block. During the placement of the pins, the workers cannot quickly place each pin according to a specific exposed length, which affects the detection efficiency. Therefore, a video detection and sorting device for pin surface defects is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies where workers cannot quickly place each pin according to a specific exposed length during the pin placement process, thus affecting detection efficiency, this utility model provides a pin surface defect video detection and sorting device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a video detection and sorting device for pin surface defects, comprising a shelf with multiple linearly arranged grooves on its upper surface. Two handles are fixedly connected to the upper surface of the shelf, and sliding grooves are formed on opposite sides of the two handles. A second threaded rod is rotatably connected inside each of the two handles, and a rotating block is fixedly connected to one end of each of the two second threaded rods. A limiting plate is provided between the two handles, with its lower surface slidably connected to the upper surface of the multiple grooves. Both ends of the limiting plate are slidably connected to the interior of the two sliding grooves, and both ends of the limiting plate are threadedly connected to the outer surfaces of the two second threaded rods. The threads inside the limiting plate at both ends are adapted to the threads on the outer surfaces of the two second threaded rods. Scale strips are fixedly connected to opposite sides of the two handles.

[0007] As a preferred embodiment of this utility model, the bottom of the shelf is provided with a base plate, and the upper surface of the base plate is provided with two support plates, and two sliding rods are fixedly connected between the two support plates.

[0008] As a preferred embodiment of this utility model, the two support plates are internally rotatably connected to a first threaded rod, and a motor is fixedly connected to one side of one of the support plates. The output end of the motor is fixedly connected to a section of the first threaded rod through a coupling.

[0009] As a preferred embodiment of this utility model, the outer surface of the first threaded rod is threadedly connected to a support platform, and the internal thread of the support platform is adapted to the thread on the outer surface of the first threaded rod. The interior of the support platform is slidably connected to the outer surfaces of the two sliding rods.

[0010] As a preferred embodiment of this utility model, the support platform has two first limiting grooves inside, a transmission rod is rotatably connected inside the support platform, and two first magnetic blocks are fixedly connected to the outer surface of the transmission rod. The two first magnetic blocks are respectively located inside the two first limiting grooves, and a rotating disk is fixedly connected to one end of the transmission rod.

[0011] As a preferred technical solution of this utility model, the lower surface of the shelf is provided with a second limiting groove, the inner top wall of the second limiting groove is closely fitted with the upper surface of the support platform, and two second magnetic blocks are fixedly connected to the inner top wall of the second limiting groove, and the lower surfaces of the two second magnetic blocks are respectively adapted to the outer surfaces of the two first magnetic blocks.

[0012] The beneficial effects of this utility model are as follows: When using this kind of ejector pin surface defect video detection and sorting device, two rotating blocks are rotated simultaneously, which drives two second threaded rods to rotate. The two second threaded rods are threadedly driven to both ends of the limiting plate, causing the limiting plate to move inside the slide groove and recess. By observing the scale on the two scale bars, the two ends of the limiting plate are moved to the required limiting position of the ejector pin to be detected. Then, the end of the ejector pin to be detected that does not need to be detected is tightly attached to the surface of the limiting plate, ensuring that the placement protrusion length of the ejector pin meets the detection requirements, thereby playing a role in quickly placing the ejector pin and improving detection efficiency.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model discloses a video detection and sorting device for pin surface defects, including a shelf 6. The upper surface of the shelf 6 has multiple linearly arranged grooves 13. Two handles 10 are fixedly connected to the upper surface of the shelf 6. Each handle 10 has a sliding groove 8 on its opposite side. A second threaded rod 9 is rotatably connected inside each handle 10. A rotating block 7 is fixedly connected to one end of each second threaded rod 9. A limiting plate 12 is provided between the two handles 10. The lower surface of the limiting plate 12 is slidably connected to the upper surface of the multiple grooves 13. Both ends of the limiting plate 12 are slidably connected to the interior of the two sliding grooves 8, and both ends of the limiting plate 12 are threadedly connected to the outer surfaces of the two second threaded rods 9. 2. The internal threads at both ends are adapted to the threads on the outer surfaces of the two second threaded rods 9. Scale strips 11 are fixedly connected to opposite sides of the two handles 10. During use, by simultaneously rotating the two rotating blocks 7, the second threaded rods 9 are driven to rotate. The two second threaded rods 9 are threadedly driven to both ends of the limiting plate 12, causing the limiting plate 12 to move within the slide groove 8 and the recess 13. Observe the scales on the two scale strips 11 to move both ends of the limiting plate 12 to the required limiting position of the ejector pin to be tested. Then, the end of the ejector pin to be tested that does not need to be tested is tightly fitted to the surface of the limiting plate 12 to ensure the placement position of the ejector pin, thereby quickly placing the ejector pin and improving testing efficiency.

[0024] The bottom of the shelf 6 is provided with a base plate 1, and the upper surface of the base plate 1 is provided with two support plates 2. Two sliding rods 3 are fixedly connected between the two support plates 2, and the support plates 2 are used to limit the position of the sliding rods 3.

[0025] The two support plates 2 are rotatably connected to a first threaded rod 5, and a motor 4 is fixedly connected to one side of one support plate 2. The output end of the motor 4 is fixedly connected to a section of the first threaded rod 5 through a coupling. The motor 4 drives the first threaded rod 5 to rotate.

[0026] The outer surface of the first threaded rod 5 is threadedly connected to a support platform 14, and the internal thread of the support platform 14 is adapted to the thread on the outer surface of the first threaded rod 5. The interior of the support platform 14 is slidably connected to the outer surfaces of the two slide rods 3. The support platform 14 serves to support the position of the limiting shelf 6.

[0027] The support platform 14 has two first limiting grooves 16 inside. A transmission rod 15 is rotatably connected inside the support platform 14. Two first magnetic blocks 18 are fixedly connected to the outer surface of the transmission rod 15. The two first magnetic blocks 18 are located inside the two first limiting grooves 16 respectively. A rotating disk 17 is fixedly connected to one end of the transmission rod 15. The rotating disk 17 drives the transmission rod 15 and the first magnetic blocks 18 to rotate.

[0028] The lower surface of the shelf 6 is provided with a second limiting groove 19. The inner top wall of the second limiting groove 19 is closely fitted with the upper surface of the support platform 14. Two second magnetic blocks 20 are fixedly connected to the inner top wall of the second limiting groove 19. The lower surfaces of the two second magnetic blocks 20 are respectively adapted to the outer surfaces of the two first magnetic blocks 18. The second magnetic blocks 20 cooperate with the first magnetic blocks 18 to attract and fix the position of the shelf 6.

[0029] During operation, first align the second limiting groove 19 with the support platform 14, insert the second magnetic block 20 into the first limiting groove 16, and place the shelf 6 above the support platform 14. Then, rotate the rotating disk 17, causing the rotating disk 17 to drive the transmission rod 15 to rotate, which in turn drives the first magnetic block 18 to rotate, causing the first magnetic block 18 and the second magnetic block 20 to stick together. Utilizing the magnetic attraction between the first magnetic block 18 and the second magnetic block 20, the shelf 6 is securely limited to the upper surface of the support platform 14, ensuring that the shelf 6 will not shake during device operation and guaranteeing the accuracy of the detection data. Then, simultaneously rotate the two rotating blocks 7, using the two rotating blocks 7 to drive the second threaded rod 9 to rotate. The two second threaded rods 9 are threadedly driven to both ends of the limiting plate 12, causing the limiting plate 12 to rotate... The slide 8 and groove 13 are moved inside, and the scales on the two scale bars 11 are observed. The two ends of the limiting plate 12 are moved to the limiting position required by the ejector pin to be tested. Then, the end of the ejector pin to be tested that does not need to be tested is tightly attached to the surface of the limiting plate 12 to ensure the placement position of the ejector pin. This achieves the function of quickly placing the ejector pin and improving the testing efficiency. The starting motor 4 drives the first threaded rod 5 to rotate. Using the threaded transmission between the first threaded rod 5 and the support table 14, the support table 14 is moved to the right to test the ejector pins in turn. After the test is completed, the rotating disk 17 is rotated to make the first magnetic block 18 disengage from the second magnetic block 20, so that the first magnetic block 18 no longer has a magnetic attraction to the second magnetic block 20. Then, the shelf 6 is moved upward to quickly remove the shelf 6 and improve the testing efficiency.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
