The device also includes:
[0022] The motherboard edge defect inspection component is mounted on the gantry 7 and is used to inspect defects on both sides of the motherboard edge.
[0023] A movable groove 4 is provided at the top center of the motherboard placement platform 2. A vertical push plate 5 is slidably installed in the movable groove 4. A horizontal straight rod 6 is fixed to the side of the push plate 5 away from the mobile phone motherboard 3. The mobile phone motherboard 3 is pushed between the two sets of defect inspection plates 10, so that one end of the mobile phone motherboard 3 is completely in contact with the side of the push plate 5. The push plate 5 is pushed by the straight rod 6, so that the push plate 5 slides on the movable groove 4 while the mobile phone motherboard 3 slides between the two sets of defect inspection plates 10.
[0024] Both sides of the inner wall of the gantry 7 are fixed with return springs 8. The ends of the two sets of return springs 8 that are close to each other are fixed with moving blocks 9. When in use, first place the mobile phone motherboard 3 on the top of the motherboard placement platform 2, and then pull the two sets of moving blocks 9 in opposite directions so that the slide bar 12 slides in the slide groove 17. The stabilizing rod 11 slides synchronously with the moving blocks 9. The return spring 8 is compressed and shortened by the sliding of the moving blocks 9.
[0025] One end of each of the two sets of stabilizing rods 11 is fixed to the bottom of the two sets of moving blocks 9 respectively. The other ends of the two sets of stabilizing rods 11 extend out of the gantry 7. When in use, first place the mobile phone motherboard 3 on the top of the motherboard placement platform 2, and then pull the two sets of moving blocks 9 in opposite directions so that the slide bar 12 slides in the slide groove 17. The stabilizing rod 11 slides synchronously with the moving block 9 to ensure the stability of the moving block 9 when it slides.
[0026] The defect inspection assembly at the edge of the motherboard includes a defect inspection plate 10, a slide bar 12, a slide groove 17, and an inspection rod 13. The top of the gantry 7 is provided with slide grooves 17 above the two sets of moving blocks 9 respectively. Vertical slide bars 12 are slidably connected in the slide grooves 17. The bottom end of the slide bar 12 is fixedly connected to the top of the moving block 9. The defect inspection plate 10 for inspecting motherboard defects is fixedly connected to one side of each set of moving blocks 9. The inspection rod 13 is fixedly connected to one side of each set of slide bars 12 that are close to each other. When the defect of the mobile phone motherboard 3 comes into contact with the defect inspection plate 10, the defect inspection plate 10 is pressed into the defect by the squeezing force of the return spring 8. The slide bar 12 slides in the slide groove 17 by the movement of the moving block 9. The slide bar 12 pushes the inspection rod 13 when it slides.
[0027] The defect inspection assembly at the edge of the motherboard also includes a comparison plate 14, a pin 15, and a defect observation rod 16. A pair of vertical comparison plates 14 are fixedly installed on the top of the gantry 7 between two sets of slide grooves 17. A horizontal pin 15 is fixedly connected between the middle of the pair of comparison plates 14. The outer wall of the pin 15 is rotatably sleeved with a defect observation rod 16 for observing defects on the motherboard. Since the end of the inspection rod 13 away from the slide rod 12 is in contact with the defect observation rod 16, the inspection rod 13 pushes the defect observation rod 16 when it moves, causing the defect observation rod 16 to rotate and tilt on the pin 15.
[0028] One end of one set of inspection rods 13 is fixed to one side of the slide rod 12 near the middle position, and the other end of the inspection rod 13 is attached to one side of the defect observation rod 16 near the bottom position. The other end of the inspection rod 13 is fixed to one side of the slide rod 12 near the top position, and the other end of the inspection rod 13 is attached to the other side of the defect observation rod 16 near the top position. By comparing the tilt of the two sets of comparison plates 14 with the defect observation rod 16, defects can be viewed on the mobile phone motherboard 3.

[0045] Working principle: In use, first place the mobile phone motherboard 3 on top of the motherboard placement platform 2, then pull the two sets of moving blocks 9 in opposite directions, causing the slide bar 12 to slide within the slide groove 17. The stabilizing rod 11 slides synchronously with the moving block 9 to ensure the stability of the moving block 9 during sliding. The return spring 8 is compressed and shortened by the sliding of the moving block 9. Then, push the mobile phone motherboard 3 between the two sets of defect inspection plates 10, so that one end of the mobile phone motherboard 3 is completely in contact with the side of the push plate 5. Use the straight rod 6 to push the push plate 5, so that the push plate 5 slides on the moving groove 4 while the mobile phone motherboard 3 slides on the two sets of defect inspection plates 10. The inspection plates 10 slide between each other. When the defect of the mobile phone motherboard 3 comes into contact with the defect inspection plate 10, the defect inspection plate 10 is pressed into the defect by the extrusion force of the return spring 8. The movement of the moving block 9 causes the slide rod 12 to slide in the slide groove 17. When the slide rod 12 slides, it pushes the inspection rod 13. Since the end of the inspection rod 13 away from the slide rod 12 is in contact with the defect observation rod 16, the inspection rod 13 pushes the defect observation rod 16 when it moves, causing the defect observation rod 16 to rotate and tilt on the pin 15. By comparing the tilt with the defect observation rod 16 using two sets of comparison plates 14, the defect of the mobile phone motherboard 3 can be viewed.
