Description

Technical Field

[0001] The present invention relates to the technical field of voltage detection, and in particular to a device for detecting voltage on pins of a microelectronic integrated circuit board. Background Art

[0002] Microelectronic integrated circuit boards (ICs) are widely used in a variety of fields, including computers, communications, consumer electronics, and medical devices. They typically integrate numerous functional circuit modules and densely packed pin structures. To ensure proper connection and stable electrical performance of PCB pins, precise pin voltage testing is essential during production, maintenance, and quality inspection.

[0003] In the actual implementation process, there are still some problems:

[0004] 1. Traditional equipment often lacks an automated cleaning module and needs to rely on manual blowing or external cleaning equipment to deal with dust and cleaning residue on the surface of the circuit board. Not only is the cleaning effect unstable, it is easy to leave traces of dust or liquid, resulting in poor probe contact and large detection errors, and also seriously affecting detection efficiency and process consistency. At the same time, the structural design of this type of device fails to achieve effective linkage between the cleaning and detection processes. The process is fragmented and the operation is cumbersome, which is not suitable for the needs of efficient and mass production detection.

[0005] 2. Traditional testing equipment also has significant deficiencies in circuit board fixing and probe contact control. Common clamping methods are mechanically demanding, inflexible, and lack buffering protection structures, which can easily cause circuit board warping, stress concentration, or solder joint damage during the fixing process. This is particularly problematic with circuit boards of varying sizes and thicknesses, resulting in poor compatibility and a limited scope of application. Furthermore, probe contact pressure cannot be adjusted, and positioning is imprecise, which can easily lead to poor contact or probe position deviation, thus affecting the accuracy of pin voltage readings. Consequently, traditional devices are unable to meet the comprehensive requirements of stability, efficiency, and intelligence for current high-density, high-precision electronic testing.

The two limiting plates 403 are connected to a locking rod 404, and the outer side of the locking rod 404 is fixedly connected to a locking protrusion 406. In actual implementation, the limiting plates 403 are slidably connected to the locking rod 404, and the outer side of the locking rod 404 is fixedly connected to a locking protrusion 406. The limiting plates 403 clamp the circuit board body 6 together with the fixing plates 405, and a structural engagement is formed between the locking rod 404 and the limiting plates 403. The locking protrusion 406 is used to achieve rapid positioning and disassembly, facilitate the clamping of circuit board bodies 6 of different sizes, and enhance the stability.

[0043] Optionally, silicone pads 407 are fixedly connected to the inner sides of both limit plates 403. The two silicone pads 407 are respectively attached to the upper and lower surfaces of the circuit board body 6. A mounting plate 408 is fixedly connected to the inner side of one of the limit plates 403. The inner side of the mounting plate 408 is fixedly connected to the third spring rod 409. The inner side of the third spring rod 409 is fixedly connected to a silicone protective plate 410. The silicone protective plate 410 is attached to the outer wall of the circuit board body 6. In actual implementation, the silicone pads 407 and silicone protective plate 410 provide flexible cushioning and protective covering, effectively preventing mechanical damage to the circuit board body 6 during the clamping process. At the same time, the third spring rod 409 provides elastic support, enhancing stability, and ensuring that the circuit board is evenly stressed, safe and reliable during testing.

[0044] Working principle: When working, the detection device body 2 is energized, the motor 516 starts to run, and its output end drives the gear 517 to rotate. The gear 517 engages with the rack 508 on the inner wall of the installation box 501, thereby driving the sliding support 511 installed in the rack 508 guide system to move in the horizontal direction. The sliding support 511 is fixedly connected to the upper end of the connecting rod 503, and the connecting rod 503 moves synchronously with the support. During the movement of the connecting rod 503, the base 507 connected to its lower end drives the spring rod 1 512 to generate a vertical force. The lower end of the spring rod 1 512 is fixed with a ball 513, and the ball 513 squeezes downward the pressing plate 505 set in the sleeve 502 directly below. When the pressing plate 505 moves downward, the spring rod 2 in the sleeve 502 514 is compressed, and at the same time, it promotes the flow of air in the closed space below the pressing plate 505. Since a one-way valve 515 is provided in the middle of the sleeve 502, the gas can only enter the transmission pipe 504 in a single direction after being compressed, and then be transported to a folding hose 509 connected to one end through the branch pipe 506. The folding hose 509 has good air conductivity and flexibility. The bottom end of the folding hose is connected to the nozzle 510, and the nozzle 510 is aimed at the surface of the circuit board body 6. As the connecting rod 503 moves back and forth, intermittent squeezing of the pressing plate 505 is achieved, so that the nozzle 510 continuously and intermittently sprays compressed air. This intermittent jet can effectively remove dust and tiny particles on the surface of the circuit board body 6. At the same time, when there is cleaning liquid residue on the surface of the circuit board body 6, it can accelerate its removal. Volatilization improves cleaning efficiency and provides good surface conditions for subsequent accurate detection of pin voltage. In order to ensure the stable position of the circuit board body 6 during the detection process and avoid the influence of movement error on the detection accuracy, the device is equipped with a stabilizing mechanism 4. Before the detection, the operator starts the electric push rod 402. The two electric push rods 402 are fixed on the connecting plates 401 on both sides of the test bench 3. The free ends of the push rods drive the fixed plates 405 to retract along the horizontal axis. A limit plate 403 that can slide up and down is provided on the inner side of the fixed plate 405. A locking rod 404 is provided between the two limit plates 403. A locking protrusion 406 is provided on the outside of the locking rod 404, which can form a locking fit with the limit plate 403. A flexible silicone pad 407 is provided on the inner side of the limit plate 403, which is respectively fixed to the upper and lower ends of the circuit board body 6. The lower surface is fitted together to form a buffer fixation, wherein a mounting plate 408 is provided in one side limit plate 403, and a spring rod 3 409 is provided on the mounting plate 408, and a silicone guard plate 410 is installed inside the mounting plate 408 to further enhance the elastic fixation and surface protection function of the circuit board body 6. After the fixation is completed, the circuit board body 6 is stably placed in the center of the test bench 3, which is convenient for the test probe to perform pin voltage detection. During the detection process, the ball 513 is positioned above the specific pin of the circuit board body 6, and the spring buffering effect ensures that the detection point is in full contact with the pin but not damaged. Combined with the subsequent voltage detection circuit, high-precision measurement of the voltage of each pin is achieved. Under the premise of ensuring the cleanliness of the surface of the circuit board body 6, the entire system is supported by the locking of the stabilizing mechanism 4 and assisted by the jet.Effectively improve the stability and accuracy of detection.
