[0002] Electronic information engineering refers to the development and research of various electronic devices and information systems. With the rapid development of modern technology, the electronic information field in our country has become more and more perfect and is widely used in various industries. Since most electronic information engineering requires the use of chips as core components, before actual use, quality inspection and processing of the chips are required.

[0003] However, when the existing equipment detects chips of a certain specification, its detection process is cumbersome and the efficiency is low. For example, most equipment needs to manually switch the opening and closing state of the fixture, increasing the waiting time by 3 - 5 seconds for a single detection cycle. Moreover, after the traditional detection equipment completes the detection, it is difficult to automatically collect the chips, which is prone to the risk of material flow interruption, and the detection of the chips is also difficult to achieve automation, making it inconvenient to use.

Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figures 1-3 , an electronic information engineering chip detection device based on machine vision, including a bottom plate 1. Four slide bars 2 are fixedly installed on the top of the bottom plate 1. The same top plate 13 is fixedly installed on the tops of the four slide bars 2. The same lifting plate 12 is slidably sleeved on the four slide bars 2. A hydraulic cylinder 14 is fixedly installed on the bottom of the top plate 13. The telescopic end of the hydraulic cylinder 14 is fixedly connected to the top of the lifting plate 12. A camera 23 is arranged at the bottom of the lifting plate 12 for capturing chip images for analysis. Lighting lamps 22 are arranged on both sides of the camera 23 at the bottom of the lifting plate 12 to ensure good lighting conditions during chip detection and improve image clarity. A collection box 3 is fixedly installed on the top of the bottom plate 1 and is located directly below the lifting plate 12. A collection hole 21 is opened on the top of the collection box 3 for receiving the detected chips for centralized processing.

[0029] Refer to Figures 4-7, limiting components are arranged on both sides of the collection hole 21, a collection component is arranged on the collection box 3, and a driving component connected to the collection component is arranged on the bottom plate 1. The limiting component includes a mounting block 8 fixedly installed on the top of the collection box 3. Two guide rods 7 penetrating through the mounting block 8 and slidably connected to it are arranged. A same limiting block 6 is fixedly installed at one end of the two guide rods 7 close to the collection hole 21, which is used to fix the position of the chip to prevent it from moving before detection. A same first auxiliary block 10 is fixedly installed at one end of the two guide rods 7 away from the collection hole 21. Two first springs 9 are fixedly connected between the first auxiliary block 10 and the mounting block 8, providing a restoring force to ensure that the limiting block 6 can automatically rebound. A second auxiliary block 11 is fixedly installed at the bottom of the lifting plate 12. The vertical section of the first auxiliary block 10 is in the shape of a right triangle, and the vertical section of the second auxiliary block 11 is in the shape of a right trapezoid. Through the limiting component, the chip with a certain specification to be detected can be automatically limited and the limit of the chip can be automatically released after detection.

[0030] The collection component includes a square block 28 fixedly installed on the outer wall of one side of the collection box 3. A hollow worm 16 penetrating through the square block 28 and rotatably connected to it is arranged. Two second rotating shafts 29 are rotatably connected between the inner walls on both sides of the collection hole 21. Rotating plates 5 are fixedly installed on the outer side walls of the two second rotating shafts 29. One end of each of the two second rotating shafts 29 penetrates through the inner wall on one side of the collection hole 21 and a worm wheel 15 located outside the collection hole 21 is fixedly installed. The hollow worm 16 is located between the two worm wheels 15 and is meshed with both worm wheels 15. Through the transmission of the hollow worm 16 and the two worm wheels 15, the stability of the collection process can be ensured. Through the collection component, the collection of the chip after detection can be realized by the opening and closing of the rotating plate 5.

[0031] The driving assembly includes a fixed plate 4 fixedly installed on the bottom plate 1. A first rotating shaft 20 is rotatably connected to a side wall of the fixed plate 4 close to the lifting plate 12. A gear 19 is fixedly installed at one end of the first rotating shaft 20. A rack 18 is fixedly installed on a side wall of the lifting plate 12 close to the fixed plate 4. A cam 35 is arranged outside the first rotating shaft 20. A first box body 17 located below the cam 35 is fixedly installed on a side wall of the fixed plate 4. A resisting rod 31 slidably connected to the first box body 17 penetrates through the top outer wall of the first box body 17. A resisting block 33 abutted against the cam 35 is fixedly installed at one end of the resisting rod 31 outside the first box body 17. A second spring 32 is fixedly connected between the resisting block 33 and the first box body 17 to provide a restoring force to ensure that the resisting block 33 can move along with the shape change of the cam 35. A first piston 30 slidably connected to its inner wall is fixedly installed at one end of the resisting rod 31 inside the first box body 17, which is used to change the air pressure in the first box body 17 to push the fluid to flow. A second box body 24 located below the hollow worm 16 is fixedly installed on the top of the bottom plate 1. A driving rod 27 slidably connected to the second box body 24 penetrates through the top outer wall of the second box body 24. A second piston 25 slidably connected to the inner wall of the second box body 24 is fixedly installed at one end of the driving rod 27 inside the second box body 24, which is used to receive the fluid pressure and push the hollow worm 16 to rotate to achieve power transmission. A conduit 26 communicating with the first box body 17 is arranged below the first piston 30. One end of the conduit 26 away from the first box body 17 communicates with the second box body 24. The end of the conduit 26 communicating with the second box body 24 is located below the second piston 25. A driving groove 36 is formed on the outer side wall of the driving rod 27. A driving block 37 is fixedly installed on the inner wall of the hollow worm 16. The outer ring of a one-way bearing 34 is fixedly installed on the outer side wall of the first rotating shaft 20, and the inner ring of the one-way bearing 34 is on the cam 35. The driving groove 36 is spiral. The driving block 37 is located in the driving groove 36 and slidably connected to the inner wall of the driving groove 36. Through the design of the spiral driving groove 36, the linear motion can be converted into a rotational motion to realize the clockwise and counterclockwise rotation of the hollow worm 16. The second piston 25 is square, and the square second piston 25 will not rotate when sliding in the second box body 24. Through the driving assembly, the power for opening and closing the rotating plate 5 of the collection assembly can be provided.

[0032] When the present invention is in use, in the initial state, the two rotating plates 5 are in a horizontal state. A chip with a certain size to be detected is placed on the two rotating plates 5. Subsequently, the hydraulic cylinder 14 is activated to make the lifting plate 12 move downward to a suitable position. During the process of the lifting plate 12 moving downward to a suitable position, the second auxiliary block 11, the camera 23, the lighting lamp 22 and the rack 18 move downward accordingly. When the rack 18 moves downward to mesh with the gear 19, the rack 18 causes the gear 19, the first rotating shaft 20 and the inner ring of the one-way bearing 34 to rotate 180 degrees in one direction. However, at this time, the inner ring and the outer ring of the one-way bearing 34 rotate idly, and the cam 35 does not rotate (the second auxiliary block 11 has not come into contact with the first auxiliary block 10 during this process). As the lifting plate 12 continues to move downward and because the second auxiliary block 11 and the first auxiliary block 10 are both provided with inclined side walls, through the mutual contact and cooperation of the two inclined side walls, the two first auxiliary blocks 10 can be made to move towards the direction close to the collection hole 21, and the first spring 9 is compressed. By providing two guide rods 7, the two limit blocks 6 can be made to approach each other, so that the chip can be tightly clamped and limited;

[0033] When the camera 23 moves downward to a proper position, after illuminating the chip through the illuminating lamp 22 and completing the detection, the lifting plate 12 can be moved upward by the hydraulic cylinder 14. As the lifting plate 12 moves upward, during the upward movement of the lifting plate 12, the second auxiliary block 11, the camera 23, the illuminating lamp 22 and the rack 18 move upward accordingly. The upward movement of the second auxiliary block 11 causes the second auxiliary block 11 to no longer be in contact with the first auxiliary block 10. Due to the elastic force generated by the compression of the first spring 9, the two limit blocks 6 move away from each other, so that the detected chip is no longer limited. Subsequently, the rack 18 meshes with the gear 19 again, and the gear 19, the first rotating shaft 20 and the inner ring of the one-way bearing 34 rotate one circle in the other direction. At this time, the inner ring and the outer ring of the one-way bearing 34 are locked, so that the cam 35 rotates one circle accordingly. During the process of the cam 35 rotating one circle, by arranging the abutting block 33, the abutting rod 31, the first piston 30 and the second spring 32, the first piston 30 can slide downward first and then upward to return to the initial position in the first box body 17. By arranging the conduit 26, part of the hydraulic oil in the first box body 17 can be first squeezed into the second box body 24 through the conduit 26, and then part of the hydraulic oil in the second box body 24 can be sucked into the first box body 17 through the conduit 26. In this way, the square second piston 25 can move up and down once, and then the driving rod 27 moves up and down once. During the up and down movement of the driving rod 27, since the second piston 25 is square, the driving rod 27 will not rotate. And because the driving block 37 is located in the spiral driving groove 36 and is slidably connected with the inner wall of the driving groove 36, the hollow worm 16 can rotate clockwise and counterclockwise for multiple circles. Since the hollow worm 16 is located between the two worm wheels 15 and is meshed with both of the two worm wheels 15, the two second rotating shafts 29 and the two rotating plates 5 can rotate in different directions. Then, the rotation of the two rotating plates 5 toward the collection box 3 causes the chip to fall into the collection box 3, and then rotate in the reverse direction again so that the two rotating plates 5 are in the horizontal state again. Repeating like this, the detected chips can be automatically collected.

[0034] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
