Description

Technical Field

[0001] This invention relates to the field of electronic equipment manufacturing and testing technology, and in particular to testing methods and apparatus for server power supply boards. Background Technology

[0002] During the production and assembly of server power supply boards, rigorous quality inspections are mandatory before shipment. These inspections typically include surface defect detection using visual equipment and electrical performance testing using test probes inserted into internal nodes. While existing server power supply board testing equipment offers some assistance with automated production, the following significant core issues remain in practical applications:

[0003] Existing testing equipment lacks a synchronized surface cleaning mechanism during transport and inspection. Dust and minute impurities are unavoidable in production environments, and these particles easily adhere to the surface of the power supply board. During visual inspection, surface dust can obscure the original features of the circuit board, causing the visual inspection camera to misinterpret dust as surface defects or component flaws. During probe-based contact testing, dust accumulation can hinder effective electrical contact between the test pins and the test points on the power supply board, leading to poor contact or abnormal test data. This environmental interference significantly reduces the accuracy of test results. Adding a separate dust removal process or manual cleaning before testing would disrupt the continuity of the testing process and severely slow down testing efficiency. Existing equipment struggles to achieve automated, wide-area dust removal using a single power source during the power supply board's movement to the inspection station.

[0004] To ensure the stability of the power supply board during testing, it is typically clamped and secured. However, traditional clamps often employ rigid clamping structures (e.g., directly locking a rigid clamping block by pushing a screw). This rigid clamping method results in direct, hard contact between the clamping block and the edge of the power supply board when clamping force is applied, lacking any buffering margin. If the clamping force is not properly controlled or if the power supply board has even slight dimensional tolerances, stress concentration can easily occur at the contact point, leading to edge wear, deformation, or even structural damage, increasing the product defect rate during production.

[0005] Furthermore, traditional testing devices typically leave the power supply board stationary after clamping. Visual inspection equipment and probe inspection mechanisms have limited single-pass coverage, making it difficult to achieve full-coverage dynamic range testing of large server power supply boards in a single clamping and fixing operation. This results in a limited detection range and a high likelihood of missed detection areas.

[0006] In summary, designing a server power supply board testing device that can simultaneously achieve automatic dust removal from a single power source during mobile testing to improve testing accuracy, while also possessing a flexible buffer clamping function to prevent board damage and enabling dynamic displacement to expand the testing range, is a technical challenge that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To achieve the above objectives, the present invention employs the following technical solution: a test device for a server power supply board, comprising: a base plate, a motor fixedly mounted on the top of the base plate, a rotating rod fixedly mounted on the output end of the motor, a belt movably sleeved on the outer surface of the rotating rod via a pulley, a short rod movably sleeved on one end of the belt via a pulley, a fan fixedly mounted on one end of the short rod, an outer cover fixedly mounted on the top of the base plate, the fan rotating inside the outer cover, a flared long tube fixedly mounted on the outer surface of the outer cover, multiple air outlet pipes fixedly mounted on the opposing surfaces of the two flared long tubes, two long rods fixedly mounted on the top of the base plate, sliders movably sleeved on the outer surfaces of the two long rods, a reciprocating lead screw fixedly mounted on one end of the rotating rod, the slider movably sleeved on the outer surface of the reciprocating lead screw, and a movable frame fixedly mounted on one side of the slider.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: The motor is started by an external power source, and the motor drives the rotating rod to rotate. At this time, the rotating rod drives the reciprocating lead screw to rotate. Under the limiting action of the two long rods, the slider slides laterally on the outer surface of the reciprocating lead screw, causing the server power supply board on the moving frame to slide above the detector and directly below the detection camera for detection. When the moving frame slides, the rotation of the rotating rod drives the belt to move through the pulley. At this time, the other end of the belt drives the short rod to rotate through the pulley. The short rod drives the fan to rotate and generate wind power. The wind power is delivered to the interior of each air outlet pipe through two trumpet-shaped long pipes and sprayed onto the server power supply board on the upper surface of the moving frame through multiple air outlet pipes. When the server power supply board passes the opposite surface of the two trumpet-shaped long pipes, the air blown out by the air outlet pipes can blow away the dust on the surface of the server power supply board, improving the accuracy of detection.

[0009] In a preferred embodiment, a threaded rod is movably embedded at the top of the movable frame, a limiting rod is movably embedded inside the movable frame, and a moving strip is fixedly installed at one end of the limiting rod.

[0010] The technical effect of adopting the above-mentioned further solution is that by rotating the threaded rod, the U-shaped clamping bar moves to one side under the limit of the limiting rod. At this time, the U-shaped clamping bar moves to another U-shaped clamping bar, and the two U-shaped clamping bars clamp and fix the server power supply board.

[0011] In a preferred embodiment, one end of the threaded rod is rotatably mounted on one side of the moving bar via a bearing. Two buffer springs are fixedly installed on the opposite side of the moving bar and the moving frame. Limiting telescopic rods are fixedly installed on the opposite side of the moving bar and the moving frame. U-shaped clamping strips are fixedly installed on the opposite ends of the two limiting telescopic rods.

[0012] The technical effect of adopting the above-mentioned further solution is that two buffer springs are provided on the opposite sides of the two U-shaped clamps. After the U-shaped clamps are clamped, they can move under the limit of the limiting telescopic rod, so that the U-shaped clamps will not make hard contact with the server power supply board and will not cause damage to both sides of the server power supply board when clamping and fixing.

[0013] In a preferred embodiment, a support bar is fixedly installed on the top of the base plate, a detection camera is fixedly installed on the bottom of the support bar, and a detector is fixedly installed on the top of the base plate.

[0014] The technical effect of adopting the above-mentioned further solution is that the detection camera takes pictures of the surface of the server power supply board, and when defects or flaws are found, the image data is transmitted to the inside of the monitor through wires.

[0015] In a preferred embodiment, an electric push rod is fixedly mounted on the top of the detector, and a detection pin is fixedly mounted on the output end of the electric push rod.

[0016] The technical effect of adopting the above-mentioned further solution is as follows: the electric push rod is activated by an external power supply, the electric push rod pushes the detection pin to move, the detection pin is inserted into the inside of the server power supply board to perform detection, and the detection data is transmitted to the inside of the display through the transmission cable for display.

[0017] In a preferred embodiment, the detector has multiple heat dissipation vents on one side, and a display is fixedly installed on the top of the base plate. The display is electrically connected to the detector via wires, and the display is also electrically connected to the detection camera via wires.

[0018] The technical effect of adopting the above-mentioned further solution is that multiple heat dissipation vents are used for heat dissipation, thereby reducing the temperature of the detector.

[0019] On the other hand, the testing method for the server power supply board includes the following steps:

[0020] Step S1: Place the server power supply board on the opposite surfaces of the two U-shaped clamps, and then rotate the threaded rod to move the U-shaped clamps to one side under the limit of the limiting rod. At this time, the U-shaped clamps move to the other U-shaped clamp. The two U-shaped clamps clamp and fix the server power supply board. Two buffer springs are provided on the opposite side of the two U-shaped clamps. After the U-shaped clamps are clamped, they can move under the limit of the limiting telescopic rod.

[0021] Step S2: Start the motor with an external power source. The motor drives the rotating rod to rotate, which in turn drives the reciprocating screw to rotate. Under the limiting action of the two long rods, the slider slides laterally on the outer surface of the reciprocating screw, causing the server power supply board on the moving frame to slide above the detector and directly below the detection camera for detection. When the moving frame slides, the rotating rod rotates and drives the belt to move through the pulley. At this time, the other end of the belt drives the short rod to rotate through the pulley. The short rod drives the fan to rotate and generate wind. The wind is delivered to the inside of each air outlet through two trumpet-shaped long tubes and sprayed onto the server power supply board on the upper surface of the moving frame through multiple air outlets. When the server power supply board passes the opposite surface of the two trumpet-shaped long tubes, the wind blown out by the air outlets can blow away the dust on the surface of the server power supply board.

[0022] Step S3: The circuit board is moved directly above the detector. The electric push rod is activated by an external power supply. The electric push rod moves the detection pin, which is then inserted into the server power supply board for detection. The detection data is transmitted to the display via a transmission cable. The detection camera takes pictures of the surface of the server power supply board. When defects or flaws are found, the image data is transmitted to the display via the cable. Simultaneously, the moving frame can move laterally during detection, moving the server power supply board to increase the detection range.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0024] 1. In this embodiment of the invention, the motor is started by an external power source, and the motor drives the rotating rod to rotate. At this time, the rotating rod drives the reciprocating lead screw to rotate. Under the limiting action of the two long rods, the slider slides laterally on the outer surface of the reciprocating lead screw, causing the server power supply board on the moving frame to slide above the detector and directly below the detection camera for detection. When the moving frame slides, the rotating rod rotates and drives the belt to move through the pulley. At this time, the other end of the belt drives the short rod to rotate through the pulley. The short rod drives the fan to rotate and generate wind power. The wind power is delivered to the interior of each air outlet pipe through two trumpet-shaped long pipes and sprayed onto the server power supply board on the upper surface of the moving frame through multiple air outlet pipes. When the server power supply board passes the opposite surface of the two trumpet-shaped long pipes, the air blown out by the air outlet pipes can blow away the dust on the surface of the server power supply board, improving the accuracy of detection.

[0025] 2. In this embodiment of the invention, the server power supply board is placed on the opposite surfaces of two U-shaped clamps. Then, by rotating the threaded rod, the U-shaped clamps move to one side under the limitation of the limiting rod. At this time, the U-shaped clamps move to the other U-shaped clamp. The two U-shaped clamps clamp and fix the server power supply board. Two buffer springs are provided on the opposite sides of the two U-shaped clamps. After the U-shaped clamps are clamped, they can move under the limitation of the limiting telescopic rod, so that the U-shaped clamps will not make hard contact with the server power supply board and will not cause damage to both sides of the server power supply board when clamping and fixing.

[0026] 3. In this embodiment of the invention, the circuit board is moved to directly above the detector, and the electric push rod is activated by an external power supply. The electric push rod pushes the detection pin to move, and the detection pin is inserted into the inside of the server power supply board for detection. The detection data is transmitted to the inside of the display through the transmission cable for display. At the same time, the detection camera takes pictures of the surface of the server power supply board. When defects or flaws are found, the image data is transmitted to the inside of the display through the cable. During the detection, the moving frame can move laterally, which moves the server power supply board to increase the detection range. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 6 This embodiment provides a technical solution: a testing device for a server power supply board, comprising: a base plate 101, a motor 102 fixedly mounted on the top of the base plate 101, a rotating rod 103 fixedly mounted on the output end of the motor 102, a belt 107 movably sleeved on the outer surface of the rotating rod 103 via a pulley, a short rod 108 movably sleeved on one end of the belt 107 via a pulley, a fan 110 fixedly mounted on one end of the short rod 108, and an outer cover 109 fixedly mounted on the top of the base plate 101, wherein the fan 110 rotates. Inside the outer cover 109, two horn-shaped long tubes 111 are fixedly installed on the outer surface of the outer cover 109. Multiple air outlet tubes 112 are fixedly installed on the opposite surfaces of the two horn-shaped long tubes 111. Two long rods 105 are fixedly installed on the top of the base plate 101. A slider 106 is movably sleeved on the outer surface of the two long rods 105. A reciprocating screw 104 is fixedly installed at one end of the rotating rod 103. The slider 106 is movably sleeved on the outer surface of the reciprocating screw 104. A movable frame 113 is fixedly installed on one side of the slider 106.

[0037] In use, the motor 102 is started by an external power source. The motor 102 drives the rotating rod 103 to rotate, which in turn drives the reciprocating lead screw 104 to rotate. Under the limiting action of the two long rods 105, the slider 106 slides laterally on the outer surface of the reciprocating lead screw 104, causing the server power supply board on the moving frame 113 to slide above the detector 119 and directly below the detection camera 125 for detection. When the moving frame 113 slides, the rotating rod 103 rotates, driving the belt 107 through the pulley. During the activity, the other end of the belt 107 drives the short rod 108 to rotate via the pulley. The short rod 108 drives the fan 110 to rotate, generating airflow. The airflow is delivered through two horn-shaped long tubes 111 to the interior of each air outlet 112, and then sprayed out through multiple air outlets 112 onto the upper surface of the moving frame 113, which is the server power supply board. When the server power supply board passes the opposite surfaces of the two horn-shaped long tubes 111, the air blown out by the air outlets 112 can blow away the dust on the surface of the server power supply board, improving the accuracy of the test.

A movable strip 117 is fixedly installed at one end of the limiting rod 1181. By rotating the threaded rod 118, the U-shaped clamping strip 115 moves to one side under the limitation of the limiting rod 1181. At this time, the U-shaped clamping strip 115 moves to another U-shaped clamping strip 115, and the two U-shaped clamping strips 115 clamp and fix the server power supply board.

[0039] like Figures 1 to 6 As shown, in one embodiment, one end of the threaded rod 118 is rotatably mounted on one side of the moving bar 117 via a bearing. Two buffer springs 114 are fixedly installed on the opposite side of the moving bar 117 and the moving frame 113. Limiting telescopic rods 116 are fixedly installed on the opposite side of the moving bar 117 and the moving frame 113. U-shaped clamping strips 115 are fixedly installed on the opposite ends of the two limiting telescopic rods 116. Two buffer springs 114 are provided on the opposite side of the two U-shaped clamping strips 115. After the U-shaped clamping strips 115 are clamped, they can move under the limitation of the limiting telescopic rods 116, so that the U-shaped clamping strips 115 will not make hard contact with the server power supply board, and will not cause damage to both sides of the server power supply board when clamping and fixing.

[0040] like Figures 1 to 6As shown, in one embodiment, a support strip 124 is fixedly installed on the top of the base plate 101, a detection camera 125 is fixedly installed on the bottom of the support strip 124, and a detector 119 is fixedly installed on the top of the base plate 101. The detection camera 125 takes pictures of the surface of the server power supply board. When defects or flaws occur, the image data is transmitted to the inside of the display 123 through wires.

The electric push rod 121 is activated by an external power supply, and the electric push rod 121 pushes the detection pin 122 to move. The detection pin 122 is inserted into the inside of the server power supply board to perform detection, and the detected data is transmitted to the inside of the display 123 for display through a transmission cable.

[0042] like Figures 1 to 6 As shown, in one embodiment, a plurality of heat dissipation vents 120 are provided on one side of the detector 119, and a display 123 is fixedly installed on the top of the base plate 101. The display 123 is electrically connected to the detector 119 via wires, and the display 123 is also electrically connected to the detection camera 125 via wires. The plurality of heat dissipation vents 120 are used for heat dissipation to reduce the temperature of the detector 119.

[0043] Working principle: In use, the server power supply board is placed on the opposite surfaces of the two U-shaped clamps 115. Then, by rotating the threaded rod 118, the U-shaped clamps 115 move to one side under the limit of the limiting rod 1181. At this time, the U-shaped clamps 115 move towards the other U-shaped clamp 115, thus clamping and fixing the server power supply board. Two buffer springs 114 are provided on the opposite sides of each U-shaped clamp 115. After clamping, the U-shaped clamps 115 can move under the limit of the limiting telescopic rod 116, allowing the U-shaped clamps 115 to... It will not make direct contact with the server power supply board, thus preventing damage to both sides of the server power supply board during clamping and fixing. After clamping and fixing, the motor 102 is started by an external power source. The motor 102 drives the rotating rod 103 to rotate, which in turn drives the reciprocating screw 104 to rotate. Under the limiting action of the two long rods 105, the slider 106 slides laterally on the outer surface of the reciprocating screw 104, causing the server power supply board on the moving frame 113 to slide above the detector 119 and directly below the detection camera 125 for detection. When the moving frame 113 slides, the rotating rod 106... 03. Rotation drives belt 107 via pulley. At the same time, the other end of belt 107 drives short rod 108 to rotate via pulley. Short rod 108 drives fan 110 to rotate, generating airflow. The airflow is delivered through two horn-shaped long tubes 111 to the interior of each air outlet 112, and then sprayed out through multiple air outlets 112 onto the upper surface of the moving frame 113, onto the server power supply board. When the server power supply board passes the opposing surfaces of the two horn-shaped long tubes 111, the air blown out by the air outlets 112 can remove dust from the surface of the server power supply board, improving the accuracy of detection. The circuit board then moves to detector 119. Directly above, an electric push rod 121 is activated by an external power source. The electric push rod 121 pushes the detection pin 122 to move, and the detection pin 122 is inserted into the inside of the server power supply board to perform detection. The detection data is transmitted to the inside of the display 123 through the transmission cable for display. At the same time, the detection camera 125 takes pictures of the surface of the server power supply board. When defects or flaws are found, the image data is transmitted to the inside of the display 123 through the cable. During the detection, the moving frame 113 can move laterally, moving the server power supply board to increase the detection range.
