Technical Field

[0001] The invention relates to the technical field of testing, in particular to testing equipment for a server mainboard. Background Art

[0002] A server motherboard test device usually consists of multiple functional modules, which are designed to detect the performance and stability of the motherboard. Through stress testing, load testing and other means, the test equipment can simulate the actual working environment, comprehensively evaluate the reliability, performance and compatibility of the motherboard, and help discover potential problems in the development and production stages.

[0003] A Chinese patent with patent announcement number CN217443493U discloses a motherboard testing device for computer production, including a fixing mechanism, a testing mechanism, and a positioning mechanism that facilitates clamping and illuminating the computer motherboard from different tilt angles. The testing mechanism is arranged above the fixing mechanism. The patent adopts a positioning mechanism, and uses an electric push rod to push the positioning plate to move left and right to clamp and position computer motherboards of different specifications to avoid deviations during the test. Then, the rotating clamp, the carrier platform and the transparent tray are driven to rotate by starting a rotating motor, and the induction lamp inside the carrier platform is used to illuminate the internal detection position of the motherboard in a graded manner, which is convenient for testing and observation from different angles, reduces manual operation, improves test results, is easy to use, and improves work efficiency.

[0004] However, the current test equipment has the following problems: the test head of the test equipment can only contact the high-side circuit when it contacts the surface of the server motherboard to connect the high and low-side circuits. Therefore, the test head cannot complete the detection of the low-side circuit, which will cause incomplete circuit test results and cannot fully evaluate the working status of the server motherboard circuit. Therefore, we propose a test device for the server motherboard. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a server motherboard testing device, which solves the problems raised in the above background technology.

The two output shafts of the dual-axis motor two will cause the two rotating rods to rotate. The rotation of the two rotating rods will drive the circular ring, short rod, card block, spring one, and arc block one connected to each other to rotate.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] See also Figure 1-Figure 7 One embodiment of the present invention is: a server motherboard testing device, comprising a base 1, a control panel 101 is fixedly connected to the side of the base 1, a motor 2 is fixedly connected to the upper side of the base 1, a bidirectional threaded rod 3 is fixedly connected to the output shaft of the motor 2, two threaded sleeves 4 are respectively threadedly connected to the circumferential surfaces of the bidirectional threaded rod 3 with opposite thread directions, the inner walls of the two threaded sleeves 4 are slidably connected with a fixer 5, a spring 2 501 is arranged between the fixer 5 and the threaded sleeve 4, a plurality of vertical rods 6 are fixedly connected to the top of the base 1, an H-shaped plate 7 is fixedly connected to the top of the H-shaped plate 7, an electric push rod 10 is fixedly connected to the top, and a U-shaped block 11 is fixedly connected to the telescopic end of the electric push rod 10, A cross bar 12 penetrates and rotates on the side of the U-shaped block 11, and a fixing ring 13 is fixedly connected to the outer wall of the cross bar 12, and a sponge detection ring 14 is fixedly connected to the outer wall of the fixing ring 13, and a gap is set between the sponge detection ring 14 and the U-shaped block 11. Through the setting of the above structure, the sponge detection ring 14 is in contact with the server mainboard. When the sponge detection ring 14 detects and contacts between the high and low surfaces of the server mainboard, the sponge detection ring 14 will deform according to the high and low surfaces of the server mainboard, so that the sponge detection ring 14 can cover the high and low surfaces of the server mainboard at the same time, thereby ensuring the accuracy of the detection of the high and low surface circuits, thereby avoiding the problem that the traditional detection head can only contact the high surface circuit when contacting the high and low surfaces of the server mainboard.

[0017] The outer walls of the cross bar 12 near both ends are fixedly connected with one-way bearings 15. At the same time, under the influence of the one-way bearings 15, the rotating wheel 16 cannot rotate when moving upward along the surface of the long block 17, ensuring that the sponge detection ring 14 will not rotate in the opposite direction, avoiding the situation where the sponge detection ring 14 is always in contact with the server motherboard on the same surface. The outer walls of the two one-way bearings 15 are fixedly connected with rotating wheels 16, and the bottom of the H-shaped plate 7 is fixedly connected with two long blocks 17. The outer walls of the two rotating wheels 16 are in contact with the two long blocks 17. Through the arrangement of the above structure, the rotation of the cross bar 12 will drive the sponge detection ring 14 to rotate through the fixed ring 13, so that the contact surface of the sponge detection ring 14 with the server motherboard is different each time, avoiding the problem of inaccurate detection caused by long-term use of the same surface of the sponge detection ring 14.

[0018] A shaking device 8 is provided on the side of the U-shaped block 11, and the shaking device 8 includes two supporting blocks 81, and the sides of the two supporting blocks 81 are penetrated and rotated with a rotating rod 82, one end of the two rotating rods 82 are fixedly connected to the two output shafts of the dual-axis motor 83, and the outer walls of the two rotating rods 82 are provided with a plurality of slots 84. The outer walls of the two rotating rods 82 are slidably connected with a circular ring 85, and the inner wall of the circular ring 85 is penetrated and slidably with a short rod 86, one end of the short rod 86 is fixedly connected with a clamping block 87, and the other end of the short rod 86 is fixedly connected with an arc block 89, and a spring 88 is provided between the clamping block 87 and the circular ring 85. The top of the threaded sleeve 4 is fixedly connected with a fixing plate 810, and the top of the fixing plate 810 is fixedly connected with an arc block 89. 11. Arc block 2 811 is located on the displacement track of arc block 1 89, and the clamping block 87 is clamped with the clamping slot 84. Through the above-mentioned structural setting, the two arc blocks 2 811 synchronously pass through the two fixing plates 810 to make the two fixers 5 squeeze the spring 2 501, so that the two fixers 5 drive the server mainboard to shake synchronously, thereby testing various jitter conditions that the server mainboard may encounter during transportation and operation, and ensuring the long-term durability of the product. Due to the nature of the sponge detection ring 14, the sponge detection ring 14 of the server mainboard will deform according to the jitter conditions during the jitter test, thereby ensuring that the sponge detection ring 14 can also fully contact with the surface of the server mainboard during the server mainboard jitter test.

[0019] When in use, the motor 2 is started through the control panel 101, and the output shaft of the motor 2 causes the bidirectional threaded rod 3 to rotate. The rotation of the bidirectional threaded rod 3 causes the two threaded sleeves 4 to move toward each other, and the two threaded sleeves 4 drive their respective fixers 5 to move toward each other. The movement of the two fixers 5 toward each other will fix and limit the server motherboard to be detected, and then the electric push rod 10 is started through the control panel 101, and the telescopic end of the electric push rod 10 will push the U-shaped block 11 to move downward, and the downward movement of the U-shaped block 11 will drive the cross bar 12 to move downward, and the downward movement of the cross bar 12 will drive the fixing ring 13 to move downward, and the downward movement of the fixing ring 13 will drive the sponge detection ring 14 to move downward, so that the sponge detection ring 14 contacts with the server motherboard. When the sponge detection ring 14 detects that it is in contact between the high and low surfaces of the server motherboard, the sponge detection ring 14 will deform according to the high and low surfaces of the server motherboard, so that the sponge detection ring 14 can At the same time, it covers the high and low surfaces of the server motherboard, thereby ensuring the accuracy of the detection of the high and low surface circuits, thereby avoiding the problem that the traditional detection head can only contact the high surface circuit when contacting the high and low surfaces of the server motherboard; when the cross bar 12 moves downward, it drives the one-way bearing 15 to move downward, and the one-way bearing 15 moves downward to drive the rotating wheel 16 to move downward. When the rotating wheel 16 moves downward, its circumferential surface is in contact with the side of the long block 17. Therefore, under the friction between the long block 17 and the rotating wheel 16, the rotating wheel 16 will rotate, and the rotation of the rotating wheel 16 will also drive the one-way bearing 15 to rotate, and the rotation of the one-way bearing 15 will drive the cross bar 12 to rotate, and the rotation of the cross bar 12 will drive the sponge detection ring 14 to rotate through the fixing ring 13, so that the contact surface of the sponge detection ring 14 with the server motherboard is different each time, avoiding the problem of inaccurate detection caused by long-term use of the same surface of the sponge detection ring 14.

[0020] The two fixers 5 move toward each other and drive the arc block 811 to move through the fixing plate 810, and then pull the two arc blocks 89 to make the two arc blocks 89 away from their respective rings 85. The movement of the two arc blocks 89 drives the short rods 86 connected to them to move respectively. The movement of the short rods 86 makes the clamping block 87 leave the clamping slot 84, and at the same time makes the clamping block 87 squeeze the spring 88, and then move the two rings 85 respectively to make the two rings 85 parallel to the two arc blocks 811, and then release the arc block 89, and the spring 88 is released. The first 88 will drive the card block 87 to move in the direction of the card slot 84 through its own elastic force, and make the card block 87 re-engage with the card slot 84. At the same time, the card block 87 moves in the direction of the card slot 84, driving the short rod 86 and the arc block 89 to move, so that the inner arc surface of the arc block 89 contacts the outer wall of the ring 85 again. Then the U-shaped block 11 moves downward and drives the support block 81 to move downward. The support block 81 moves downward and drives the rotating rod 82, the dual-axis motor 83, the card slot 84, the ring 85, the short rod 86, the card block 89, and the card slot 84. The block 87, the spring 1 88, and the arc block 1 89 move downward, so that the surface of the ring 85 contacts the surface of the arc block 2 811, and then the double-axis motor 2 83 is started through the control panel 101. The two output shafts of the double-axis motor 2 83 will cause the two rotating rods 82 to rotate. The rotation of the two rotating rods 82 will drive the respectively connected ring 85, the short rod 86, the clamping block 87, the spring 1 88, and the arc block 1 89 to rotate. The rotation of the two arc blocks 1 89 will simultaneously contact the two arc blocks 2 811, so that the two arc blocks 2 811 are synchronously connected. The two fixing plates 810 are used to squeeze the two fixing devices 5 against the spring 2 501, so that the two fixing devices 5 drive the server mainboard to shake synchronously, thereby testing various shaking conditions that the server mainboard may encounter during transportation and operation, and ensuring the long-term durability of the product; due to the properties of the sponge detection ring 14, the sponge detection ring 14 will deform according to the shaking conditions during the shaking test of the server mainboard, thereby ensuring that the sponge detection ring 14 can also fully contact the surface of the server mainboard during the server mainboard shaking test.

[0021] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, an overpressure prevention device 9 is provided on the side of the long block 17, and the overpressure prevention device 9 includes a fixed rod 91, one end of the fixed rod 91 is slidably connected to the side of the long block 17, and the outer wall of the fixed rod 91 is slidably connected to a moving block 92, and the side of the moving block 92 is fixedly connected to a circular ring block 93, and the outer wall of the circular ring block 93 is fixedly connected to an L-shaped block plate 94, and the bottom of the L-shaped block plate 94 is fixedly connected to a supporting long block 95, and the side of the threaded sleeve 4 away from the fixer 5 is fixedly connected to a connecting block 96, and the side of the connecting block 96 is fixedly connected to a placing block 97, and the top two sides of the placing block 97 are set to be oblique, and the top of the placing block 97 It is hollow, and the hollow part of the placement block 97 is located on the displacement track of the support long block 95. The side of the circular ring block 93 is rotatably connected to the side of the circular ring 85. The inner wall of the circular ring block 93 contacts the outer wall of the rotating rod 82. Through the setting of the above structure, it is difficult for the electric push rod 10 to continue to push the U-shaped block 11 to move downward, thereby avoiding the problem that the electric push rod 10 pushes the U-shaped block 11 with excessive pressure, resulting in deformation of the middle part of the server motherboard, and making the two support long blocks 95 parallel to the hollow parts of the two placement blocks 97, thereby realizing the positioning of the two support long blocks 95 and the two placement blocks 97, ensuring that the two support long blocks 95 can accurately enter the interior of the placement block 97.

[0022] When in use, the movement of the two threaded sleeves 4 will drive the connecting blocks 96 connected to them to move, and the movement of the connecting blocks 96 will drive the placement blocks 97 to move to the positions where the two fixers 5 fix the server motherboards to be tested. At the same time, the movement of the two circular rings 85 will drive the circular ring block 93 to move, and the movement of the circular ring block 93 will drive the moving block 92 to move on the outer wall of the fixing rod 91. At the same time, the movement of the circular ring block 93 will drive the L-shaped block plate 94 to move, and the movement of the L-shaped block plate 94 will drive the supporting long block 95 to move. When the two circular rings 85 are parallel to the two arc blocks 811, the two supporting long blocks 95 will be parallel to the hollow parts of the two placement blocks 97. The downward movement of the rotating rod 82 and the circular ring 85 will drive the circular ring block 93, the L-shaped block plate 94, the supporting long block 95, and the moving block 92 to move downward. The movement will cause the fixing rod 91 to move downward on the side of the long block 17. When the sponge detection ring 14 contacts the server motherboard, the supporting long block 95 will move to the inside of the placement block 97 and encounter the resistance of the placement block 97, so that the supporting long block 95 passes through the L-shaped block plate 94, the circular ring block 93, the rotating rod 82, the circular ring 85, the supporting block 81, and the U-shaped block 11, making it difficult for the electric push rod 10 to continue to push the U-shaped block 11 to move downward, thereby avoiding the problem that the electric push rod 10 pushes the U-shaped block 11 with excessive pressure, causing the middle part of the server motherboard to deform; at the same time, when the two circular rings 85 are parallel to the two arc blocks 811, the two supporting long blocks 95 will be parallel to the hollow parts of the two placement blocks 97, thereby realizing the positioning of the two supporting long blocks 95 and the two placement blocks 97, ensuring that the two supporting long blocks 95 can accurately enter the interior of the placement block 97.
