Technical Field

[0001] This utility model relates to the field of computer testing, specifically a device for detecting defects in computer motherboards. Background Technology

[0002] Computer motherboard defect detection devices are indispensable tools in the electronics manufacturing industry. They help manufacturers ensure motherboard quality and reduce the production of defective products. Traditional computer motherboard defect detection methods mostly rely on manual visual inspection or simple mechanical testing. However, these methods have significant limitations. Manual visual inspection cannot cover all areas of the motherboard, especially for some hidden or subtle defects, which are easily missed. Furthermore, the efficiency and accuracy of manual inspection are greatly affected by individual experience and skill levels, making it difficult to achieve standardized and consistent testing. Simple mechanical testing methods often can only detect specific types of defects and are difficult to effectively identify complex and varied defect types. Therefore, we propose a computer motherboard defect detection device. Utility Model Content

The device also includes:

[0022] The adjustment component, which is set on the motherboard detection base plate 1, is used to perform defect inspection on different locations of the computer motherboard 5.

[0023] The raised blocks 4 are arranged in several groups, and the groups of raised blocks 4 are distributed at equal intervals.

[0024] Two sets of clamping plates 6 are slidably installed on the top of several sets of raised blocks 4.

The two ends of the computer motherboard 5 are slidably connected in the two sets of inner grooves 15 respectively.

[0025] Two sets of inner grooves 15 are each fixed with hemispherical steel balls 16 near their respective ends. When it is necessary to perform defect detection on the computer motherboard 5, the two ends of the computer motherboard 5 are first placed in the two sets of inner grooves 15 on the two sets of clamping plates 6, and the two ends of the computer motherboard 5 are positioned between the two sets of steel balls 16 to prevent the computer motherboard 5 from shifting.

[0026] The adjustment assembly includes a limiting rod 7, an outer groove 8, a mounting plate 9, an adjusting rod 10, a limiting block 11, and a component plate 12. Both sets of clamping plates 6 have outer grooves 8 at their opposite ends, with the limiting rod 7 slidably connected within the outer grooves 8. One set of clamping plates 6 has a mounting plate 9 fixedly connected to its top near both ends, while the other set of clamping plates 6 has a component plate 12 fixedly connected to its top near both ends. Horizontal adjusting rods 10 are rotatably mounted on one side of each component plate 12. Two sets of... The spaced limiting blocks 11 allow the end of the adjusting rod 10 to slide into the slot 14 on the circular groove 13.

The component plate 12 has a slot 14 above the circular groove 13. The adjustment rod 10 is movably connected in the circular groove 13, and the limiting block 11 is slidably connected in the slot 14. The component plate 12 is locked by the two sets of limiting blocks 11 to ensure the consistency of the sliding of the two sets of clamping plates 6. When it is necessary to push the computer motherboard 5 back and forth, or when it is necessary to adjust and test the computer motherboard 5 back and forth, the adjustment rod 10 is pushed or pulled, so that the two sets of adjustment rods 10 drive the two sets of clamping plates 6 to slide on the top of the shim block 4 through the mounting plate 9 and the slot 14.

[0028] One end of the limiting rod 7 is slidably connected to the outer groove 8, and the other end of the limiting rod 7 extends out of the main board detection base plate 1. The two sets of limiting rods 7 slide simultaneously in the outer groove 8 on the clamping plate 6.

[0045] Working principle: When defect detection of the computer motherboard 5 is required, firstly, place both ends of the computer motherboard 5 into the two sets of inner grooves 15 on the two sets of clamping plates 6, and position both ends of the computer motherboard 5 between the two sets of steel balls 16 to prevent displacement of the computer motherboard 5. Then, slide the end of the adjusting rod 10 into the slot 14 on the circular groove 13. The limiting block 11 passes through the slot 14 through the sliding of the adjusting rod 10. Next, rotate the adjusting rod 10 180 degrees, causing the two sets of limiting blocks 11 to rotate on both sides of the component board 12. The two sets of limiting blocks 11 then lock the component board 12 in place, thus securing the two sets of adjusting rods 10. Pull the clamping rod 10 left and right to make the two clamping plates 6 slide left and right on the top of the shim block 4. The two limiting rods 7 slide on the motherboard detection base plate 1 as the clamping plates 6 slide. The component board 12 is locked by the two limiting blocks 11 to ensure the consistency of the sliding of the two clamping plates 6. When it is necessary to push the computer motherboard 5 back and forth, or when it is necessary to adjust and detect the computer motherboard 5 back and forth, push or pull the adjusting rod 10 to make the two adjusting rods 10 drive the two clamping plates 6 to slide on the top of the shim block 4 through the mounting plate 9 and the slot 14. The two limiting rods 7 slide simultaneously in the outer groove 8 on the clamping plate 6.
