[0031] Referring to Figure 1 as shown, the present utility model provides a technical solution: A PCB circuit board AOI detection device with a positioning function, including a detection device body 1, a positioning device 2 is provided on the surface of the detection device body 1. By setting the positioning device 2, the effect of positioning and clamping the circuit board to the exact center of the detection device body 1 can be achieved, avoiding the situation where when the staff places the circuit board, they cannot accurately place the circuit board to the exact center of the detection device body 1, resulting in errors in the detection results and inaccurate detection results, improving the practicability of the device. A moving device 3 is provided on the surface of the detection device body 1. By setting the moving device 3, the effect of facilitating the staff to place the circuit board can be achieved, avoiding the situation where when the staff places the circuit board on the surface of the sliding plate 21, due to the close distance between the sliding plate 21 and the detection device body 1, it is inconvenient for the staff to place the circuit board on the surface of the sliding plate 21, improving the practicability of the device.

[0032] Next, specifically describe the specific settings and functions of its positioning device 2 and moving device 3.

[0033] Refer to Figure 2 、 Figure 3 and Figure 4As shown in the figure, in this embodiment: The positioning device 2 includes a sliding plate 21, which is slidably connected to the surface of the detection device body 1. A fixed frame 22 is fixedly connected to the surface of the sliding plate 21. Four first springs 23 are fixedly connected to the inner surface of the fixed frame 22. The four first springs 23 are divided into two groups. One end of two first springs 23 is fixedly connected to a positioning plate 24. Four sliding grooves 25 are formed on the surface of the sliding plate 21. The inner surfaces of the four sliding grooves 25 are all slidably connected with sliding blocks 26. The four sliding blocks 26 are divided into two groups. The surfaces of two sliding blocks 26 are fixedly connected to the positioning plate 24. A protective pad 27 is slidably connected to the side of the positioning plate 24 away from the first spring 23. The size of the protective pad 27 is adapted to the size of the positioning plate 24. When the staff needs to detect the circuit board, move the positioning plate 24. The positioning plate 24 drives the protective pad 27 to move. The positioning plate 24 drives the sliding block 26 to slide on the inner surface of the sliding groove 25, and the first spring 23 is compressed. When the positioning plate 24 moves to a suitable position, place the circuit board on the surface of the sliding plate 21, release the positioning plate 24, and the resilience of the first spring 23 drives the positioning plate 24 to slide. The positioning plate 24 drives the protective pad 27 to move until the surface of the protective pad 27 contacts the circuit board. At this time, the staff can detect the circuit board. The protective pad 27 achieves the effect of protecting the circuit board, avoiding the situation that when the resilience of the first spring 23 drives the positioning plate 24 to move to the surface of the circuit board, the impact force is too large and the circuit board is damaged. Two screw rods 28 are inserted into the positioning plate 24 with internal threads. One end of the two screw rods 28 is rotatably connected to the protective pad 27. When the protective pad 27 is damaged after long-term use and cannot effectively protect the circuit board, the protective pad 27 needs to be replaced at this time. Rotate the screw rod 28, and the screw rod 28 rotates inside the positioning plate 24. When the screw rod 28 completely disengages from the protective pad 27, the screw rod 28 releases the fixation of the protective pad 27. Move the protective pad 27, and the protective pad 27 slides on the surface of the positioning plate 24. When the protective pad 27 completely disengages from the surface of the positioning plate 24, the staff can replace the protective pad 27. After sliding the new protective pad 27 to the surface of the positioning plate 24, rotate the screw rod 28, and the screw rod 28 rotates inside the positioning plate 24. When the screw rod 28 rotates into the protective pad 27, the screw rod 28 fixes the protective pad 27. The screw rod 28 achieves the effect of fixing the protective pad 27, and at the same time, it is convenient for the staff to quickly disassemble and replace the damaged protective pad 27 to avoid the situation that the protective effect of the protective pad 27 is reduced after the protective pad 27 is damaged. A connection groove is formed at one end of the screw rod 28, and an operation block 29 is fixedly connected to the inner surface of the connection groove of the screw rod 28. When the staff needs to replace the protective pad 27, rotate the operation block 29, and the operation block 29 drives the screw rod 28 to rotate inside the positioning plate 24. When the screw rod 28 completely disengages from the protective pad 27, the screw rod 28 releases the fixation of the protective pad 27. At this time, the staff can replace the protective pad 27. The operation block 29 achieves the effect of facilitating the staff to rotate the screw rod 28.The situation where the surface of the screw rod 28 is relatively smooth, making it inconvenient for the staff to rotate the screw rod 28, is avoided.

[0034] Refer to Figure 5 、 Figure 6 and Figure 7As shown in the figure, specifically, the mobile device 3 includes a U-shaped frame 31. The U-shaped frame 31 is fixedly connected to the surface of the detection device body 1. Two sliding holes 32 are formed on the surface of the U-shaped frame 31. The inner surfaces of the two sliding holes 32 are both slidably connected with sliders 33. One side of the two sliders 33 close to each other is fixedly connected to a sliding plate 21. Two fixing rods 34 are fixedly connected to the surface of the U-shaped frame 31. The arc surface of the fixing rod 34 is slidably connected with an operating plate 35. One side of the operating plate 35 close to the U-shaped frame 31 is fixedly connected to an inserting rod 36. A slot is formed on the surface of the slider 33. The size of the slot of the slider 33 is adapted to the size of the inserting rod 36. When the staff needs to place the circuit board on the surface of the sliding plate 21, move the operating plate 35. The operating plate 35 slides on the arc surface of the fixing rod 34. The operating plate 35 drives the inserting rod 36 to move. When the operating plate 35 moves to a suitable position, move the sliding plate 21. The sliding plate 21 slides on the surface of the detection device body 1. The sliding plate 21 drives the slider 33 to slide on the inner surface of the sliding hole 32. When the sliding plate 21 moves to a suitable position, at this time, the inserting rod 36 is located directly in front of the slot of the slider 33. Push the operating plate 35. The operating plate 35 drives the inserting rod 36 to move. When the inserting rod 36 is inserted into the inner surface of the slot of the slider 33, the inserting rod 36 fixes the slider 33, and the slider 33 fixes the sliding plate 21. At this time, the staff can place the circuit board on the surface of the sliding plate 21. The inserting rod 36 achieves the effect of fixing the sliding plate 21, avoiding the situation that when the staff places the circuit board on the surface of the sliding plate 21, the sliding plate 21 slides, making it difficult for the staff to place the circuit board on the surface of the sliding plate 21. A second spring 37 is fixedly connected to the surface of the slider 33. The two ends of the second spring 37 are respectively fixedly connected to the slider 33 and the sliding hole 32. When the staff needs to place the circuit board on the surface of the sliding plate 21, move the operating plate 35. The operating plate 35 drives the inserting rod 36 to move. When the operating plate 35 moves to a suitable position, pull the sliding plate 21, and the second spring 37 is stretched. When the staff moves the sliding plate 21 to a suitable position, push the operating plate 35. The operating plate 35 drives the inserting rod 36 to move. When the inserting rod 36 is inserted into the inner surface of the slot of the slider 33, the inserting rod 36 fixes the slider 33, and the slider 33 fixes the sliding plate 21. After the staff places the circuit board on the surface of the sliding plate 21, pull the operating plate 35. The operating plate 35 drives the inserting rod 36 to move. When the inserting rod 36 completely disengages from the inner surface of the slot of the slider 33, the inserting rod 36 releases the fixation of the slider 33. The resilience of the second spring 37 drives the slider 33 to slide on the inner surface of the sliding hole 32. The slider 33 drives the sliding plate 21 to slide until the sliding plate 21 moves back to its original position. The resilience of the second spring 37 achieves the effect of automatically bringing back the sliding plate 21. At the same time, the resilience of the second spring 37 can limit the sliding of the sliding plate 21.

[0035] Working principle: When the staff needs to detect the circuit board, move the positioning plate 24. The positioning plate 24 drives the protective pad 27 to move. The positioning plate 24 drives the sliding block 26 to slide on the inner surface of the chute 25, and the first spring 23 is compressed. After the positioning plate 24 moves to a suitable position, place the circuit board on the surface of the sliding plate 21. Release the positioning plate 24, and the resilience of the first spring 23 drives the positioning plate 24 to slide. The positioning plate 24 drives the protective pad 27 to move until the surface of the protective pad 27 contacts the circuit board. At this time, the staff can detect the circuit board. When the protective pad 27 is damaged after long-term use and cannot effectively protect the circuit board, the protective pad 27 needs to be replaced. Rotate the operating block 29, and the operating block 29 drives the screw rod 28 to rotate in the positioning plate 24. When the screw rod 28 completely disengages from the protective pad 27, the screw rod 28 releases the fixation of the protective pad 27. Move the protective pad 27, and the protective pad 27 slides on the surface of the positioning plate 24. When the protective pad 27 completely disengages from the surface of the positioning plate 24, the staff can replace the protective pad 27. After sliding the new protective pad 27 onto the surface of the positioning plate 24, rotate the operating block 29, and the operating block 29 drives the screw rod 28 to rotate in the positioning plate 24. When the screw rod 28 rotates into the protective pad 27, the screw rod 28 fixes the protective pad 27.

[0036] When the staff needs to place the circuit board on the surface of the sliding plate 21, move the operating plate 35. The operating plate 35 drives the insertion rod 36 to move. After the operating plate 35 moves to a suitable position, pull the sliding plate 21, and the second spring 37 is stretched. The sliding plate 21 slides on the surface of the detection device body 1. The sliding plate 21 drives the slider 33 to slide on the inner surface of the sliding hole 32. After the staff moves the sliding plate 21 to a suitable position, push the operating plate 35. The operating plate 35 drives the insertion rod 36 to move. When the insertion rod 36 is inserted into the inner surface of the slot of the slider 33, the insertion rod 36 fixes the slider 33. The slider 33 fixes the sliding plate 21. At this time, the staff can place the circuit board on the surface of the sliding plate 21. After placing it, pull the operating plate 35. The operating plate 35 drives the insertion rod 36 to move. When the insertion rod 36 completely disengages from the inner surface of the slot of the slider 33, the insertion rod 36 releases the fixation of the slider 33. The resilience of the second spring 37 drives the slider 33 to slide on the inner surface of the sliding hole 32. The slider 33 drives the sliding plate 21 to slide until the sliding plate 21 returns to its original position.
