Description

Technical Field

[0001] The present invention belongs to the technical field of computer motherboard voltage detection, and particularly relates to a computer motherboard voltage multi-point detection device and a detection method thereof. Background Art

[0002] With the rapid development of computer technology, the complexity and functional requirements of computer motherboards are constantly increasing. As the core component of a computer system, a computer motherboard carries numerous electronic components and circuits, and its stability and reliability are directly related to the normal operation of the entire computer system. However, during operation, the motherboard may be affected by various factors, such as power fluctuations, component aging, environmental humidity, etc., resulting in abnormal voltages, which in turn affect the performance of the computer and may even cause hardware failures.

[0003] Traditional computer motherboard voltage detection methods usually adopt a single-point detection method, that is, one or several key positions on the motherboard are selected for voltage detection. However, this single-point detection method has obvious limitations. First, the voltage distribution on the computer motherboard is not completely uniform, and single-point detection cannot comprehensively reflect the voltage state of the entire motherboard. Second, single-point detection cannot effectively detect voltage changes under multiple load conditions and is difficult to meet the high requirements for voltage detection in modern complex computer systems. In addition, the manual detection method is not only inefficient but also prone to inaccurate detection results due to fatigue or improper operation.

[0004] To overcome these deficiencies and improve the accuracy and reliability of computer motherboard voltage detection, it is particularly important to develop a voltage detection device that can achieve multi-point detection. Such a device should be able to simultaneously detect multiple key points on the motherboard, obtain voltage data in real time, and promptly discover potential voltage abnormalities through data analysis. At the same time, the device should also have an automatic detection function to reduce dependence on manual operations and improve detection efficiency. Summary of the Invention

[0016] Further, a detection method for a computer motherboard voltage multi-point detection device includes the following steps:

[0017] S1: When performing voltage detection on the computer motherboard, place the computer motherboard on the upper end of the base, turn on the motor one on the side of the installation seat, the motor one drives the drive shaft to rotate through the output end, the drive shaft rotates to drive the bevel gear one to rotate, the bevel gear one rotates to drive the bevel gear two to rotate, the bevel gear two rotates to drive the threaded rod to rotate, and the threaded rod rotates to drive the two T-shaped sliders to approach each other. The two T-shaped sliders approaching each other drive the positioning plate one and the positioning plate two to approach each other, thereby positioning and fixing the computer motherboard.

[0018] S2: When one of the threaded rods rotates, the threaded rod rotates to drive the gear one to rotate, the gear one rotates to drive the synchronous belt to rotate, the synchronous belt rotates to drive the gear two to rotate, the gear two rotates to drive the bidirectional lead screw to rotate, and the bidirectional lead screw rotates to drive the other two T-shaped sliders to approach each other, thereby improving the stability of the sliding process of the positioning plate one and the positioning plate two.

[0019] S3: When detecting the computer motherboard, first input the size data of the computer motherboard into the controller. When the positioning plate 1 and the positioning plate 2 approach each other, they will drive the connecting plate 1 and the connecting plate 2 to approach each other. At this time, the distance between the infrared emitter and the infrared receiver will change. When the distance between the infrared emitter and the infrared receiver reaches the distance set by the controller, the controller will control the start and stop of the motor 1, thus avoiding pinching the computer motherboard.

[0020] S4: When detecting the computer motherboard, adjust the position of the mounting ring on the surface of the voltage detection head until the red dot emitted by the laser pen aligns with the detection point of the computer motherboard. At this time, the voltage detection head will descend to exactly align with the detection point for voltage detection. At the same time, fix the mounting ring with the fastening bolt. The laser positioning components on the side of each group of voltage detection heads will emit red dots to the upper end of the computer motherboard. According to the detection points of the computer motherboard, control the electric push rod and the motor 2. The electric push rod drives the slider to slide inside the chute, thereby adjusting the longitudinal position of the voltage detection head.

[0021] S5: Turn on the motor 2. The motor 2 drives the bevel gear 3 to rotate through the output end. The rotation of the bevel gear 3 drives the bevel gear 4 to rotate. The rotation of the bevel gear 4 drives the screw rod to rotate. The rotation of the screw rod can drive the nut block to move. The movement of the nut block can drive the position of the voltage detection head to be adjusted until the red dot emitted by the laser positioning component aligns with the detection point of the computer motherboard. Then, by turning on the cylinder, the cylinder drives the voltage detection head to descend, thereby performing voltage detection on the computer motherboard.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The present invention is provided with a positioning and fixing mechanism for the computer motherboard. The positioning and fixing mechanism can ensure the stability of the motherboard during the detection process, avoid inaccurate detection data caused by the movement or vibration of the motherboard. Through the automatic limiting and positioning functions, the detection device can quickly place the motherboard in the detection area, reducing the time and effort of manual adjustment.

[0024] 2. By providing a multi-point voltage detection device, the multi-point voltage detection device can simultaneously detect multiple key points on the motherboard, covering a wider area, thus more comprehensively reflecting the voltage state of the motherboard. This multi-point detection method can accurately locate the position of voltage anomalies, avoid missing potential problems due to single-point detection. Multi-point detection can reduce misjudgment caused by single-point failures or measurement errors, improving the accuracy and reliability of the detection results. At the same time, through the comprehensive analysis of multi-point data, the overall health status of the motherboard can be better evaluated. Description of the Drawings

[0063] Working principle and usage process of the present invention: When the present invention is in use, when detecting the voltage of a computer motherboard, place the computer motherboard on the upper end of the base 1, and turn on the first motor 81 on the side of the mounting seat 82. The first motor 81 drives the drive shaft 812 to rotate through the output end. The rotation of the drive shaft 812 drives the first bevel gear 89 to rotate. The rotation of the first bevel gear 89 drives the second bevel gear 810 to rotate. The rotation of the second bevel gear 810 drives the threaded rod 811 to rotate. The rotation of the threaded rod 811 can drive the two T-shaped sliders 84 to approach each other. The two T-shaped sliders 84 approaching each other can drive the first positioning plate 86 and the second positioning plate 87 to approach each other, thereby positioning and fixing the computer motherboard. When one of the threaded rods 811 rotates, the threaded rod 811 rotates to drive the first gear 882 to rotate. The rotation of the first gear 882 drives the synchronous belt 881 to rotate. The rotation of the synchronous belt 881 drives the second gear 883 to rotate. The rotation of the second gear 883 drives the bidirectional lead screw 884 to rotate. The rotation of the bidirectional lead screw 884 can drive the other two T-shaped sliders 84 to approach each other, thereby improving the stability of the sliding process of the first positioning plate 86 and the second positioning plate 87. When detecting the computer motherboard, first input the size data of the computer motherboard into the controller 2. When the first positioning plate 86 and the second positioning plate 87 approach each other, they will drive the first connecting plate 851 and the second connecting plate 853 to approach each other. At this time, the distance between the infrared emitter 852 and the infrared receiver 854 will change. When the distance between the infrared emitter 852 and the infrared receiver 854 reaches the distance set by the controller 2, the controller 2 will control the start and stop of the first motor 81 at this time, thereby avoiding clamping the computer motherboard. When detecting the computer motherboard, by adjusting the position of the mounting ring 762 on the surface of the voltage detection head 71 until the red dot emitted by the laser pen 763 is aligned with the detection point of the computer motherboard. At this time, the voltage detection head 71 descends to exactly align with the detection point for voltage detection. At the same time, fix the mounting ring 762 through the fastening bolt 761. The laser positioning assembly 76 on the side of each voltage detection head 71 will emit a red dot to the upper end of the computer motherboard. According to the detection points of the computer motherboard, control the electric push rod 75 and the second motor 733. The electric push rod 75 drives the slider 74 to slide inside the chute 72, thereby adjusting the longitudinal position of the voltage detection head 71. Turn on the second motor 733. The second motor 733 drives the third bevel gear 732 to rotate through the output end. The rotation of the third bevel gear 732 drives the fourth bevel gear 736 to rotate. The rotation of the fourth bevel gear 736 drives the screw 734 to rotate. The rotation of the screw 734 can drive the nut block 735 to move. The movement of the nut block 735 can drive the position of the voltage detection head 71 to be adjusted until the red dot emitted by the laser positioning assembly 76 is aligned with the detection point of the computer motherboard. Then, by turning on the cylinder 5, the cylinder 5 drives the voltage detection head 71 to descend, thereby detecting the voltage of the computer motherboard.
