Description

Technical Field

[0001] This invention relates to the field of computer testing technology, specifically to a microcomputer motherboard interface plug-in / plug-out testing device and method. The device uses a sensor plate to adjust the plug-in / plug-out travel of the connector, enabling it to adapt to the plug-in / plug-out testing requirements of different motherboard models. Background Technology

[0002] A microcomputer, or "microcomputer" for short, is a small, fully functional electronic computer. Common microcomputers in daily life include desktop computers, laptop computers, and all-in-one computers. Regardless of the type of microcomputer, its external interface is usually installed on the motherboard and connected to external devices through the casing or chassis. After the motherboard is manufactured, the motherboard interface must undergo plug-in / plug-out testing. This test can check whether the interface is making good contact and whether it can transmit data normally. In existing interface plug-in / plug-out tests, manual plugging and unplugging is not only time-consuming and labor-intensive, but can also damage the motherboard due to uneven force applied during repeated tests. Since the motherboard sizes of different microcomputer models vary, when using an interface plug-in / plug-out testing device to test different types of motherboards, after fixing the motherboard, the working stroke of the plug needs to be constantly adjusted according to the size of the motherboard to ensure that the plug is not inserted too deeply or too shallowly into the interface, which would lead to test errors. Due to the wide variety of microcomputer motherboards, frequent adjustments will result in low work efficiency.

[0003] In summary, the present invention provides a microcomputer motherboard interface plugging and unplugging test device and test method to solve the above problems. Summary of the Invention

Detailed Implementation

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] This invention provides a microcomputer motherboard interface plug-in / plug-out testing device, comprising: a workbench 1 and a control panel 2. The control panel 2 is fixedly connected to the top of the workbench 1. A pair of grooves 11 are symmetrically formed on both sides of the workbench 1, and a rack 12 is fixedly connected in the groove 11. A groove 13 is formed on the top of the workbench 1. A pair of slide rails 14 are symmetrically fixedly connected to the top of the workbench 1. A plug-in / plug-out assembly 3 is provided on the top of the workbench 1. The plug-in / plug-out assembly 3 is slidably connected to the slide rails 14. An electric telescopic rod is fixedly connected to the top of the plug-in / plug-out assembly 3. 31. The output end of the electric telescopic rod 31 vertically penetrates the outer shell of the plug-in assembly 3 and is fixedly connected to a motor 32. The output end of the motor 32 is fixedly connected to a rotating shaft 33. Two pairs of grooves 340 are symmetrically opened on the rotating shaft 33. An elastic element 342 is provided in the groove 340. One end of the elastic element 342 is fixedly connected to the inner wall of the groove 340, and the other end of the elastic element 342 is fixedly connected to a limit block 341. A bracket 34 and a bracket 35 are fixedly connected inside the plug-in assembly 3. A sleeve is rotatably connected to the bracket 34. A first sleeve 38 is fixedly connected to a gear 36, and a second sleeve 39 is rotatably connected to a bracket 35. A second gear 37 is fixedly connected to the second sleeve 39. Both the first sleeve 38 and the second sleeve 39 have a pair of slots 310. The second gear 37 meshes with the rack 12. The diameter of the first rotating shaft 33 is the same as the inner diameter of the first sleeve 38 and the second sleeve 39. The lower end face of the limiting block 341 on the first rotating shaft 33 is arc-shaped, and the top of the limiting block 341 on the first rotating shaft 33 is arc-shaped. The limiting block 341 enters the sleeve... When sleeve 38 or sleeve 39 is inserted, the arc-shaped part of the limiting block 341 will contact the inner wall of sleeve 38 or sleeve 39 and be squeezed back into groove 340. As the rotating shaft 33 rotates, the limiting block 341 will be pushed into the slot 310 by the elastic element 342 when passing through the slot 310. After the limiting block 341 enters the slot 310 on sleeve 38 or sleeve 39, the rotating shaft 33 will drive one of them to rotate, which will drive gear 36 or gear 37 to rotate, so that the insertion and removal assembly 3 moves to the interface position and performs the interface insertion and removal test.

[0021] The insertion / extraction assembly 3 has a central shaft 311 fixedly connected inside. One end of the central shaft 311 is rotatably connected to a gear 312, which meshes with a gear 36. A crank 313 is fixedly connected to the bottom of the gear 312. A rotating shaft 314 is rotatably connected to the bottom of the crank 313. A connecting rod 315 is rotatably connected to the bottom of the rotating shaft 314. A limiting groove 317 is formed on the side of the insertion / extraction assembly 3. There is a push rod 316, which is slidably connected to the limiting groove 317. One end of the push rod 316 is rotatably connected to the connecting rod 315, and the other end of the push rod 316 is fixedly connected to the telescopic platform 318. When the rotating shaft 33 drives the gear 36 to rotate, it will drive the gear 312 to rotate through meshing, thereby causing the crank 313 and the connecting rod 315 to move, so that the push rod 316 can reciprocate within the limiting groove 317, thereby realizing the insertion and removal test function of the insertion and removal assembly 3.

[0022] The telescopic platform 318 is slidably connected to the worktable 1. The top of the telescopic platform 318 has a first sliding groove 319, within which a slider 320 is installed. Stoppers 321 are fixedly connected to the openings at both ends of the first sliding groove 319. The bottom of the first sliding groove 319 has a fourth groove 322. A mounting base 323 is fixedly connected to the top of the slider 320. The top of the mounting base 323 has a mounting groove 324, and the bottom of the mounting groove 324 has a second sliding groove 325. A wire is installed within the second sliding groove 325. The rod 326 has one end extending from one side of the mounting base 323 and fixedly connected to a handle 327. The other end of the rod 326 is rotatably connected to the side wall of the slide groove 325. A pair of clamping plates 328 are provided on the rod 326. The bottom of the clamping plates 328 has a horizontally opened screw hole, which is threaded into the rod 326. Rotating the handle 327 drives the rod 326 to rotate, which can adjust the distance between the pair of clamping plates 328 to accommodate different plug models. The slider 320 has a range of motion between the two stops 321.

[0023] The mounting groove 324 has a pair of symmetrical sliding grooves 329. Each sliding groove 329 contains an elastic element 330. One end of the elastic element 330 is fixedly connected to the inner wall of the sliding groove 329, and the other end of the elastic element 330 is fixedly connected to a sliding plate 331. The sliding plate 331 is slidably connected to the sliding groove 329. A pair of pillars 332 are fixedly connected to one side of the sliding plate 331. A contact plate 333 is fixedly connected to one end of each pillar 332, and a lever 334 is fixedly connected to the other side of the sliding plate 331. When the contact plate 333 contacts the side of the main board during operation, the contact plate 333, pillars 332, and sliding plate 331 move along the sliding groove 329 as the mounting base 323 moves. The elastic element 330 is compressed, and the lever 334 also moves accordingly.

[0024] The mounting groove 324 has a vertically formed through groove 335 at its bottom. A support column 336 is fixedly connected within the through groove 335. A turntable 337 is rotatably connected to the support column 336. Connecting plates 338 are rotatably connected to both sides of the turntable 337. A pin 339 is rotatably connected between a pair of connecting plates 338. The bottom of the pin 339 is located within a groove 322. The turntable 337 has a 90-degree arc-shaped notch. A lever 33... The bottom of 4 is arc-shaped. When the bottom of the toggle block 334 contacts the arc-shaped notch of the turntable 337, the turntable 337 will rotate as the toggle block 334 continues to move, which in turn will drive the connecting plate 338 and the pin 339 to move. When the pin 339 disengages from the groove 4 322, the slider 320 and the mounting base 323 are slidably connected to the telescopic platform 318. When the pin 339 is located in the groove 4 322, the slider 320 and the mounting base 323 are fixedly connected to the telescopic platform 318.

[0025] The groove 13 is fixedly connected to an electric telescopic rod 41, the output end of which is fixedly connected to a lifting platform 4. The lifting platform 4 has a sliding groove 43, and the side of the lifting platform 4 is fixedly connected to an electric telescopic rod 44. The output end of the electric telescopic rod 44 passes through the sliding groove 43. The electric telescopic rod 41 is used to adjust the vertical height of the motherboard to adapt to different models of motherboards.

[0026] The lifting platform 4 has a fixed plate 45 fixedly connected to its top. The top of the lifting platform 4 has a sliding groove 47, which is connected to a sliding groove 43. The output end of the electric telescopic rod 44 is fixedly connected to a connecting block 46. The connecting block 46 extends through the sliding groove 47 to the top of the lifting platform 4. A fixed plate 42 is fixedly connected to the top of the connecting block 46. The fixed plate 42 is slidably connected to the lifting platform 4. When the electric telescopic rod 44 is activated, it drives the connecting block 46 and the fixed plate 42 to move, cooperating with the fixed plate 45 to clamp the main board, facilitating subsequent plugging and unplugging tests.

[0027] In this design, rectangular grooves 411 are formed on the opposite surfaces of the first fixing plate 45 and the second fixing plate 42. A connecting shaft 48 is fixedly connected within the rectangular groove 411, and a locking block 49 is rotatably connected to the connecting shaft 48. An elastic element 410 is provided within the rectangular groove 411. One end of the elastic element 410 is fixedly connected to the inner wall of the rectangular groove 411, and the other end is fixedly connected to the locking block 49. The locking block 49 has an arc-shaped portion and an inclined portion. When the motherboard is clamped between the first fixing plate 45 and the second fixing plate 42, the side of the motherboard... It will first contact the inclined part on the card block 49, and as the distance between the first fixing plate 45 and the second fixing plate 42 decreases, the side of the motherboard will slide along the inclined part on the card block 49 to the arc-shaped part. When the motherboard slides on the arc-shaped part of the card block 49, the card block 49 will rotate around the connecting shaft 48. At this time, the elastic element 3 410 is compressed until the inclined part of the card block 49 rotates to the horizontal plane. When the inclined part of the card block 49 rotates, it will lift the motherboard from the bottom of the motherboard, so that there is a gap between it and the lifting platform 4, so that the telescopic platform 318 can pass under the motherboard during subsequent insertion and removal tests.

[0028] A test method for plugging and unplugging a microcomputer motherboard interface includes the following steps: S1. Place the motherboard of the microcomputer on the lifting platform 4 and clamp it with fixing plate 1 45 and fixing plate 2 42. S2. Secure the plug between a pair of clamps 328 on the mounting base 323; S3. Start motor 32, which drives plug-in assembly 3 to move along slide rail 14 to motherboard interface position through gear 37 meshing with rack 12; S4. Start the electric telescopic rod 31 to raise the motor 32, so that it drives the telescopic platform 318 and the plug to reciprocate to perform interface plugging and unplugging detection. S5. Control the detection process and obtain detection data through control panel 2. Example 1:

[0029] like Figure 10-12As shown, in this embodiment, the microcomputer motherboard to be tested is placed between the first fixed plate 45 and the second fixed plate 42 on the lifting platform 4. The electric telescopic rod 44 is activated, and its output end drives the connecting block 46 and the second fixed plate 42 to move. After the two sides of the motherboard enter between the second fixed plate 42 and the first fixed plate 45 respectively, they will first contact the inclined part of the locking block 49. As the electric telescopic rod 41 acts, the distance between the first fixed plate 45 and the second fixed plate 42 decreases, and the side of the motherboard will slide from the inclined part of the locking block 49 to the arc-shaped part. The continued sliding of the motherboard will push the locking block 49 to rotate around the connecting shaft 48, so that the elastic element 410 is compressed until the locking block 49 cooperates with the second fixed plate 42 to clamp one side of the motherboard. At the same time, the first fixed plate 45 will also cooperate with the locking block 49 inside to clamp the other side of the motherboard, lifting and fixing the motherboard. While the motherboard is fixed to the lifting platform 4, there is a gap between its bottom and the top of the lifting platform 4.

[0030] like Figure 1-5 As shown, after the motherboard is fixed, place the plug corresponding to the interface to be tested on the mounting slot 324. The part to be inserted into the interface should extend fully out of the mounting base 323. Turn the handle 327 to drive the lead screw 326 to rotate, reducing the distance between the pair of clamping plates 328 and clamping the plug. Start the electric telescopic rod 31, whose output end drives the motor 32 to move, pushing the motor 32 vertically downward through the shaft 33 until the lower limit block 341 on the shaft 33 enters the sleeve 39. During the process of the shaft 33 driving the limit block 341 into the sleeve 39, the arc-shaped part at the bottom will first contact the inner wall of the sleeve 39. As the shaft 33 continues to move downward... As the device moves downwards, the arc-shaped portion of the limiting block 341 is squeezed by the inner wall of the sleeve 39 and gradually retracts into the groove 340. At this time, the elastic element 342 is compressed, and the motor 32 is started. Its output end drives the rotating shaft 33 to rotate. When the limiting block 341 rotates to the position of the slot 310, the elastic element 342 will push the limiting block 341 from the groove 340 into the slot 310. The side of the limiting block 341 will fit against the inner wall of the slot 310. At this time, the rotation of the rotating shaft 33 will drive the sleeve 39 and the gear 37 to rotate on the bracket 35, mesh with the rack 12, and drive the plug-in assembly 3 to move along the slide rail 14 on the worktable 1, moving the plug to the position of the interface.

[0031] like Figure 6-7As shown, when the electric telescopic rod 31 is activated, it drives the motor 32 and the rotating shaft 33 to move vertically upward. The rotating shaft 33 disengages from the sleeve 39, and the lower limit block 341 on the rotating shaft 33 also disengages from the slot 310 in the sleeve 39. At the same time, the upper limit block 341 on the rotating shaft 33 enters the sleeve 38. During this process, the arc-shaped part at the top of the limit block 341 contacts the inner wall of the sleeve 38. As the rotating shaft 33 continues to move upward, the limit block 341 is squeezed into the groove 340 by the inner wall of the sleeve 38, and the elastic element 342 is compressed. At this time, the motor 32 is activated. When the rotating shaft 33 drives the limit block 341 to rotate to the position of the slot 310, The limiting block 341 is pushed from the groove 340 into the slot 310 by the elastic element 342. At this time, the rotating shaft 33 drives the sleeve 38 and the gear 36 to rotate on the bracket 34, meshing with the gear 312, which drives the gear 312 to rotate around the central shaft 311, thereby driving the crank 313 to rotate. The rotation of the crank 313 will cooperate with the connecting rod 315, driving the push rod 316 to move back and forth in the limiting groove 317, so that the telescopic table 318 drives the plug to move back and forth to perform the insertion and removal test. Each insertion and removal test will transmit data to the motherboard through the interface and display it on the control panel 2. After the test is completed, the number of insertions and removals is compared with the number of data transmissions and the integrity to test whether the interface has good contact.

[0032] like Figure 7-9 As shown, due to the differences in motherboard size among different types of microcomputers, during the process of the telescopic platform 318 driving the mounting base 323 to insert the plug into the interface, the contact plate 333 will contact the side of the motherboard. As the plug is gradually inserted into the interface, the contact plate 333 is pushed, causing the sliding plate 331 to slide within the sliding groove 329. The elastic element 330 is continuously compressed. When the plug is completely inserted into the interface, the lever 334 on one side of the sliding plate 331 will contact the notch on the turntable 337, causing the turntable 337 to rotate around the support column 336. When the disk 337 rotates 90 degrees, it will pull the pin 339 to disengage it from the groove 322. After the pin 339 disengages from the groove 322, the slider 320 and the slide groove 319 slide relative to each other. The push rod 316 continues to push the telescopic platform 318 to move under the motherboard. The mounting base 323 and the slider 320 will stop at the position where the plug is just inserted into the interface. This prevents the push rod 316 from continuing to push the telescopic platform 318 to move after the plug has been fully inserted into the interface when the stroke of the push rod 316 is greater than the distance between the plug and the interface, which would cause an impact to the motherboard.

[0033] like Figure 8-9As shown, when the push rod 316 pulls the telescopic platform 318 back, it will pull the telescopic platform 318 out from under the main board. At this time, the plug is still connected to the interface until the slider 320 contacts the stop 321, which drives the mounting base 323 and the plug to be pulled out of the interface. When the gear 312 rotates one revolution, the entire insertion and removal process is completed. The telescopic platform 318 and the mounting base 323 return to the initial position. During the return process, the elastic element 2 330 will push the slide plate 331 out of the slide groove 329, causing the toggle block 334 to drive the turntable 337 to rotate. When the slider 320 contacts the stop 321, it pushes the pin 339 into the groove 4 322, changing the connection between the telescopic platform 318 and the mounting base 323 into a fixed connection.

[0034] It should be noted that the working stroke of the push rod 316 is designed according to the smallest model of motherboard that the device can detect. When detecting a larger motherboard, the relative sliding between the mounting base 323 and the telescopic stage 318 is used to offset the change in the size of the motherboard, so as to meet the needs of interface plugging and unplugging tests of different models of motherboards.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
