[0002] As the core component of a computer system, the strength and stability of the motherboard directly affect the performance and lifespan of the entire system. A motherboard strength testing device is a professional device used to evaluate the strength and reliability of the motherboard under various working conditions. By simulating various stress conditions in actual use, it detects whether the motherboard has structural defects or insufficient strength.

[0003] In existing technologies, when conducting strength tests on computer motherboards, limitations in manual testing techniques make it difficult to detect whether plugging and unplugging connectors on the motherboard will cause damage. Secondly, when testing the strength of the motherboard, it is impossible for humans to detect the data of motherboard connectors undergoing multiple plugging and unplugging cycles. Moreover, in simulating multiple plugging and unplugging cycles of the motherboard in reality, it is impossible for humans to detect at which stage the motherboard is damaged. Finally, during the testing process, workers need to frequently change the testing head, which affects the testing efficiency.

[0017] Compared with the prior art, the present invention provides a computer hardware motherboard strength testing device, which has the following beneficial effects:

[0018] 1. A computer hardware motherboard strength testing device, comprising a panel, testing components, etc., wherein in use, the computer motherboard is placed on a second rectangular fixing block, and then a second telescopic rod is activated, which lowers the component tray. When it reaches a suitable height, a built-in micro motor is activated, causing the component tray to rotate the corresponding testing plug to the testing outlet. Then, a third telescopic rod is activated to attract the top of the testing plug with a magnetic ring, thereby aligning the testing plug with the testing socket. During alignment, when the pressure sensor just contacts the bottom of the tested socket, it indicates that the testing plug and the tested socket are properly matched.

[0019] 2. A computer hardware motherboard strength testing device, comprising a panel, data reading components, etc., in use, when the testing plug is being tested, the force of repeated insertion and removal is different, causing the tested connector on the surface of the computer motherboard to move slightly downward. When it is pulled out, a corresponding displacement also occurs. This displacement data is read through a scale bar so that workers can make judgments based on the corresponding data. Through the above design, the pressure data of the computer motherboard can be quickly read.

[0020] 3. A computer hardware motherboard strength testing device, comprising a panel, displacement components, etc., allows for the following operation: when the computer motherboard needs to be tested at the side testing port, the motherboard is removed, and then the first motor is started. This causes the bidirectional lead screw to move towards the H-shaped support rod via four sets of first threaded blocks, thereby causing two sets of U-shaped clamping plates to move towards each other and engage the edge of the computer motherboard with the two sets of clamping plates on the inner wall of the U-shaped clamping plates. Then, the first rectangular fixing block is restored, and the second motor is started, causing the computer motherboard to rotate so that the side testing port and testing plug are aligned horizontally. Through the above design, the computer motherboard can be flipped over, facilitating a comprehensive test of the computer motherboard's strength. Attached Figure Description

[0032] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a computer hardware motherboard strength testing device.

[0034] In one typical implementation of this application, such as Figure 1-10 As shown, a computer hardware motherboard strength testing device includes a panel 1, four sets of support columns 6 are fixed at the four bottom corners of the panel 1, an L-shaped support plate 5 is fixed in the center of the top rear side of the panel 1, and a computer motherboard 13 is installed on the top of the panel 1.

[0035] As a preferred embodiment of this invention, it should be noted before use that the computer motherboard 13 is placed into the second rectangular fixing block 20 manually or by a robotic arm. It should be noted that the computer motherboard 13 does not shift when placed into the second rectangular fixing block 20.

[0036] Furthermore, in the above scheme, the detection component 3 is installed at the bottom of the L-shaped support plate 5. The detection component 3 is used to detect the strength of the computer motherboard 13. The detection component 3 includes a second telescopic rod 32 fixed to the bottom of the L-shaped support plate 5. The output end of the second telescopic rod 32 is fixedly connected to the mounting base plate 35. The bottom end of the mounting base plate 35 is fixedly connected to the accessory library 33. A connecting rod is fixedly connected to the center of the inner wall of the accessory library 33. An accessory plate 34 is fixedly fixed to the top of the connecting rod. Several sets of mounting slots are opened on the inner wall of the accessory plate 34. A detection plug 36 is adsorbed on the inner wall of each mounting slot. Support rods are set at both ends of the detection plug 36. Several sets of pressure sensors 37 are fixedly fixed at equal intervals at the bottom of the support rods. A detection outlet 38 is opened at the bottom of the accessory library 33. The detection outlet 38 is adapted to the detection plug 36. A third telescopic rod 39 is fixedly connected to the top of the inner wall of the accessory library 33 near the detection plug 36. A magnetic ring 40 is sleeved on the output end of the third telescopic rod 39. The bottom of the magnetic ring 40 attracts the detection plug 36. The data reading component 4 includes a component fixed to the surface The first telescopic rod 26 is located at the top of the plate 1. A first rectangular fixing block 19 is fixedly connected to the output end of the first telescopic rod 26. A base plate 30 is slidably connected to the inner wall of the first rectangular fixing block 19. The base plate 30 has equidistant grooves around its perimeter. Gears 28 are rotatably connected to the inner walls of each groove. Sliding grooves 31 are formed on the inner walls of the first rectangular fixing block 19 near the gears 28. Racks 27 are slidably connected to the inner walls of several sets of sliding grooves 31 at their centers. The racks 27 mesh with the gears 28. The tops and bottoms of the racks 27 are symmetrically fixed. There are two sets of second springs 29. The ends of several sets of second springs 29 away from the rack 27 are fixedly connected to the slide groove 31. The top of the base plate 30 is fixedly connected to a second rectangular fixing block 20. The inner wall of the second rectangular fixing block 20 is connected to the computer motherboard 13. A through groove 22 is opened on the front side of the first rectangular fixing block 19. A pointer 23 is fixedly connected to the rack 27 on the front side. The pointer 23 is slidably set on the inner wall of the through groove 22. A scale strip 21 is fixed on the front side of the first rectangular fixing block 19 near the through groove 22.

[0037] Specifically, after the computer motherboard 13 is placed inside the second rectangular fixing block 20, the first rectangular fixing block 19 is moved upward to the detection height by activating the first telescopic rod 26. The first telescopic rod 26 then stops. At this point, the second telescopic rod 32 is activated, causing the parts storage compartment 33 to move downward. During this movement, the micro motor inside the parts storage compartment 33 starts, causing the parts board 34 to rotate. Then, the corresponding detection plug 36 is rotated to the detection outlet 38 as needed, after which the micro motor stops. Simultaneously, the third telescopic rod 39 inside the parts storage compartment 33 starts. It should be noted that the output end of the third telescopic rod 39 is fitted with a magnetic ring 40, which can interact with the detection... The tops of the test plugs 36 attract each other. After the test plug 36 is extended from the test outlet 38 by the third telescopic rod 39, the third telescopic rod 39 will stop. As the second telescopic rod 32 continues to move downward, when the test plug 36 is in contact with the socket to be tested on the surface of the computer motherboard 13, the pressure sensors 37 on both sides of the test plug 36 will slowly approach the bottom of the socket being tested. When they are in contact with the bottom of the socket being tested, the surface of the pressure sensor 37 will be in contact with it. At this time, the pressure sensor 37 will transmit the signal to the second telescopic rod 32, causing the second telescopic rod 32 to stop. It should be noted that there are several situations in this testing process, which will be described below.

[0038] First: When the test plug 36 just makes contact with the interface being tested, power on the computer motherboard 13 and then determine whether it is intact.

[0039] Second: After the test plug 36 matches the interface being tested, continue to apply pressure through the second telescopic rod 32. At this time, the test port needs to be observed.

[0040] Third: When the second telescopic rod 32 pulls out the test plug 36, there is a certain resistance between the test plug 36 and the interface being tested. Therefore, after pulling it out, the computer motherboard 13 is powered on again to check whether the computer motherboard 13 is intact.

[0041] Under the three conditions described above, the state of the computer motherboard 13 will be reflected on the scale bar 21. Specifically, when the test plug 36 contacts the tested port on the computer motherboard 13, the pointer 23 will point to the corresponding value on the scale bar 21. Simultaneously, after the second telescopic rod 32 continues to apply pressure, the pointer 23 will also point to the corresponding value on the scale bar 21. These values ​​will be fed back to the operator to determine the strength of the computer motherboard 13. It should be noted that when the computer motherboard 13 is placed on the second rectangular fixing block 20, the computer motherboard 13 itself has gravity, causing a slight deviation in the pointer 23. Therefore, the operator should remove this deviation when calculating the strength change to obtain more accurate data. Finally, when the test plug 36 is pulled out of the tested port on the computer motherboard 13, if the pointer 23 shows abnormal data on the scale bar 21, it is determined that a break or crack has occurred at that point. This abnormal data will be fed back to the operator to facilitate appropriate decision-making.

[0042] In this embodiment, the displacement component 2 includes four sets of fixing blocks 15 symmetrically fixed to the top of the panel 1. Two sets of fixing blocks 15 on the front side are rotatably connected to bidirectional lead screws 14 on their facing sides, and two sets of fixing blocks 15 on the rear side are also rotatably connected to bidirectional lead screws 14 on their facing sides. The two sets of bidirectional lead screws 14 are symmetrically arranged, and two sets of first threaded blocks 8 are symmetrically threaded onto the outer walls of the two sets of bidirectional lead screws 14. H-shaped support rods 9 are fixedly connected to the tops of the two sets of first threaded blocks 8 on the left side, and H-shaped support rods 9 are fixedly connected to the tops of the two sets of first threaded blocks 8 on the right side. The two sets of H-shaped support rods 9 are symmetrically arranged, and two sets of first rotating shafts 11 are symmetrically rotatably connected to their facing sides. U-shaped clamps 12 are fixedly connected to the facing sides of both sets of first rotating shafts 11. Two sets of second motors 10 are symmetrically fixed on opposite sides. The output ends of the two sets of second motors 10 correspond one-to-one with the first rotating shaft 11 and are fixedly connected. A second synchronous wheel 18 is rotatably connected to the outer wall of the left fixed block 15. A first synchronous wheel 16 is rotatably connected to the outer wall of the left fixed block 15. The first synchronous wheel 16 and the second synchronous wheel 18 are connected by a synchronous belt 17. The second synchronous wheel 18 is coaxially fixedly connected to the front double-acting screw 14. The first synchronous wheel 16 is coaxially fixedly connected to the rear double-acting screw 14. A first motor 7 is fixedly connected to the outer wall of the left fixed block 15. The output end of the first motor 7 is fixedly connected to the second synchronous wheel 18. Several sets of first springs 24 are symmetrically fixed at the upper and lower ends of the inner wall of the U-shaped clamp 12. The clamp 25 is fixedly connected to the opposite end of each set of first springs 24.

[0043] When the computer motherboard 13 needs to be inspected at the side detection port, the computer motherboard 13 is taken out by a robotic arm or manually. Then, the first motor 7 is started, and the two sets of bidirectional lead screws 14 bring the two H-shaped support rods 9 closer together. When the two H-shaped support rods 9 are close together, the two first rotating shafts 11 set on the opposite side of the H-shaped support rods 9 will bring the U-shaped clamping plate 12 closer to the computer motherboard 13. When the U-shaped clamping plate 12 is gradually engaged at the edge of the computer motherboard 13, the clamping plate 25 will firmly clamp the computer motherboard 13 under the elastic force of the first spring 24. At the same time, the two sets of second motors 10 are started to flip the computer motherboard 13 and repeat the above steps to complete the inspection of the detection port on the side of the computer motherboard 13.

[0044] Working principle of this invention: After the computer motherboard 13 is placed inside the second rectangular fixing block 20, the first telescopic rod 26 is activated to move the first rectangular fixing block 19 to the detection height. The first telescopic rod 26 then stops. At this point, the second telescopic rod 32 is activated, causing the parts storage compartment 33 to move downwards. During this movement, a micro motor inside the parts storage compartment 33 starts, causing the parts board 34 to rotate. Then, the corresponding detection plug 36 is rotated to the detection outlet 38 as needed, after which the micro motor stops. Simultaneously, the third telescopic rod 39 inside the parts storage compartment 33 is activated. It should be noted that a magnetic ring 40 is fitted onto the output end of the third telescopic rod 39. The magnetic ring 40 is capable of... Attracted to the top of the detection plug 36, the third telescopic rod 39 extends the detection plug 36 from the detection outlet 38. After the third telescopic rod 39 stops, the second telescopic rod 32 continues to move downwards. When the detection plug 36 comes into contact with the required connector on the surface of the computer motherboard 13, the pressure sensors 37 on both sides of the detection plug 36 slowly approach the bottom of the connector. When they come into contact with the bottom of the connector, the surface of the pressure sensors 37 will be in contact with it. At this point, the pressure sensors 37 transmit a signal to the second telescopic rod 32, causing the second telescopic rod 32 to stop. It should be noted that there are several scenarios in this detection process, which are described below.

[0045] First: When the test plug 36 just makes contact with the interface being tested, power on the computer motherboard 13 and then determine whether it is intact.

[0046] Second: After the test plug 36 matches the interface being tested, continue to apply pressure through the second telescopic rod 32. At this time, the test port needs to be observed.

[0047] Third: When the second telescopic rod 32 pulls out the test plug 36, there is a certain resistance between the test plug 36 and the interface being tested. Therefore, after pulling it out, the computer motherboard 13 is powered on again to check whether the computer motherboard 13 is intact.

[0048] Under the three conditions described above, the state of the computer motherboard 13 will be reflected on the scale bar 21. Specifically, when the test plug 36 contacts the tested port on the computer motherboard 13, the pointer 23 will point to the corresponding value on the scale bar 21. Simultaneously, after the second telescopic rod 32 continues to apply pressure, the pointer 23 will also point to the corresponding value on the scale bar 21. These values ​​will be fed back to the operator to determine the strength of the computer motherboard 13. It should be noted that when the computer motherboard 13 is placed on the second rectangular fixing block 20, the computer motherboard 13 itself has gravity, causing a slight deviation in the pointer 23. Therefore, the operator should remove this deviation when calculating the strength change to obtain more accurate data. Finally, when the test plug 36 is pulled out of the tested port on the computer motherboard 13, if the pointer 23 shows abnormal data on the scale bar 21, it is determined that a break or crack has occurred at that point. This abnormal data will be fed back to the operator to facilitate appropriate decision-making.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
