Technical Field

[0001] This invention relates to the field of computer motherboard performance testing technology, and in particular to a device for testing the hardware resistance to breakage and pressure of computer motherboards. Background Technology

[0002] The computer motherboard, installed inside the computer case, is one of the most basic and important components of a computer. It connects hardware such as the graphics card, CPU, memory, and hard drive. During the manufacturing process, testing the motherboard's resistance to breakage and pressure is a crucial test. This involves applying pressure to the motherboard using a testing device to ensure it can withstand mechanical stress during actual use, improving product reliability and durability, guaranteeing product quality, and reducing the probability of malfunctions.

[0003] During the production process of computer hardware motherboards, testing equipment is needed to test their resistance to breakage and pressure. Existing testing equipment cannot be used for computer motherboards of various sizes, making the installation work before testing the computer motherboards cumbersome and reducing the testing efficiency of computer motherboards. Summary of the Invention

A placement plate is fixedly connected to the bottom of the slider, and the top of the placement plate is slidably connected to the bottom of the clamping plate. The outer wall of the connecting rod is slidably connected to the side wall of the outer shell.

[0011] Furthermore, the rotating mechanism includes a push rod, and a third sliding groove is provided inside the push rod. A pressing plate is slidably connected to the inner wall of the third sliding groove, and a second spring is fixedly connected to the side wall of the pressing plate. The end of the second spring that is away from the pressing plate is fixedly connected to the inner wall of the third sliding groove.

[0012] Furthermore, a sliding plate is slidably connected to the inner wall of the first chute, a limit frame is fixedly connected to the inner wall of the outer shell, and a third spring is fixedly connected to the inner wall of the limit frame. The end of the third spring that is away from the limit frame is fixedly connected to the outer wall of the sliding plate.

[0013] Furthermore, the outer wall of the housing is fixedly connected to a mounting bracket, and a second hydraulic cylinder is fixedly installed inside the mounting bracket. The output shaft of the second hydraulic cylinder is fixedly connected to a ring. A circular groove is provided at the end of the connecting rod that is away from the clamping plate, and the outer wall of the ring is rotatably connected to the inner wall of the circular groove.

[0014] Furthermore, the collecting mechanism includes a sealing plate, and the bottom of the sealing plate has a toothed groove.

[0017] Compared with existing technologies, the above solution has the following advantages:

[0018] 1. By pressing the side of the computer motherboard with a backing plate, the side of the computer motherboard is clamped. During the movement of the backing plate, the first rotating plate drives the clamping block to rotate with the end of the second rotating plate. After the slide bar has slid, the placement plate will detach from the bottom of the clamping plate, thus avoiding any impact on the subsequent testing process. Through the cooperation of the clamping block and the clamping plate, the bottom and top of the computer motherboard can be clamped. The output distance of the second hydraulic cylinder can be adjusted according to the size of the computer motherboard, and then the computer motherboard can be automatically clamped in multiple directions.

[0019] 2. When the horizontal plate is slid back to its original position, it will simultaneously move the second spring, causing the top of the pressing plate to contact the end of the sliding plate and then press it. This pressing will cause the sliding plate to rotate, and the connecting rod will also drive the clamping plate to rotate synchronously. Since the two clamping plates rotate in different directions, the two clamping plates will drive the two sides of the computer motherboard to rotate, thus realizing the automatic torsion test after the computer motherboard has completed the withstand voltage test, improving the comprehensiveness of the test.

[0020] 3. As the push rod slides down along the inner wall of the connecting groove, the pull rope will not pull the rack. Then, the two sealing plates will slide away from each other, while the toothed groove will cause the two push plates to slide closer together. After sliding, the two push plates will stick together. Then, the computer motherboard that fails the test will break or shatter during the test. The broken computer motherboard fragments will fall down into the collection chamber, which facilitates the collection of the computer motherboard that fails the test and makes it easier to process it later.

[0031] Example 1, please refer to Figure 1-4A device for testing the resistance to breakage and pressure of computer motherboard hardware includes a housing 1, a clamping mechanism 2 inside the housing 1, an mounting arm 3 fixedly connected to the outer wall of the housing 1, a first hydraulic cylinder 4 fixedly mounted on the top of the mounting arm 3, a pressure component 14 fixedly mounted on the output shaft of the first hydraulic cylinder 4, a horizontal plate 5 fixedly connected to the outer wall of the output shaft of the first hydraulic cylinder 4, a collection cavity 11 inside the housing 1, a mounting frame 7 fixedly connected to the outer wall of the housing 1, a second hydraulic cylinder 8 fixedly mounted inside the mounting frame 7, a ring 9 fixedly connected to the output shaft of the second hydraulic cylinder 8, a circular groove 10 at the end of a connecting rod 210 that is away from the clamping plate 201, and the outer wall of the ring 9 rotatably connected to the inner wall of the circular groove 10.

[0032] Specifically, the clamping mechanism 2 includes a clamping plate 201, which can clamp computer motherboards of different sizes from multiple angles before performance testing. A slide rod 202 is slidably connected through the side wall of the clamping plate 201, and a stop plate 203 is fixedly connected to the end of the slide rod 202. A first spring 204 is fixedly connected to the end of the stop plate 203 that is close to the slide rod 202, and the end of the first spring 204 that is away from the stop plate 203 is fixedly connected to the side wall of the clamping plate 201. A connecting post 205 is fixedly connected to the side wall of the stop plate 203, and a first rotating plate 206 is rotatably connected to the end of the connecting post 205 that is away from the stop plate 203. A second rotating plate 207 is rotatably connected to the end of the first rotating plate 206 that is away from the connecting post 205, and the second rotating plate 207 is rotatably connected to the end of the first rotating plate 206 that is away from the first rotating plate 206. A clamping block 208 is fixedly connected to the end of the clamping plate 201. A limit rod 209 is rotatably connected inside the clamping plate 201. The outer wall of the second rotating plate 207 is fixedly connected to the inside of the limit rod 209. A connecting rod 210 is fixedly connected to the side wall of the clamping plate 201. A first sliding groove 211 is opened through the outer wall of the connecting rod 210. A second sliding groove 212 is opened on the side wall of the clamping plate 201. A slider 214 is slidably connected to the inner wall of the second sliding groove 212. A tension spring 213 is fixedly connected to the side wall of the slider 214. The end of the tension spring 213 that is far away from the slider 214 is fixedly connected to the inner wall of the second sliding groove 212. A placement plate 215 is fixedly connected to the bottom of the slider 214. The top of the placement plate 215 is slidably connected to the bottom of the clamping plate 201. The outer wall of the connecting rod 210 is slidably connected to the side wall of the outer shell 1.

[0033] During the production of computer motherboards, they need to undergo fracture resistance and pressure resistance tests. These tests assess the quality and reliability of the motherboards, thereby reducing the probability of production accidents. First, the motherboards to be tested are placed on the similar end surfaces of multiple placement plates 215. Then, based on the motherboard dimensions, a command is issued to the second hydraulic cylinder 8, causing it to output to a specified stroke. The second hydraulic cylinder 8 then drives the output shaft ring 9 to output power. The ring 9 then moves synchronously through the circular groove 10, causing the connecting rod 210 to move. During this process, the outer wall of the connecting rod 210 penetrates the side wall of the outer casing 1 and slides inward. Simultaneously, the connecting rod 210 drives the clamping plate 201 to move on the inner wall of the outer casing 1. Through the relative movement of the two clamping plates 201, the distance between them gradually decreases. When they reach a certain position, the side wall of the abutment plate 203 contacts the side of the computer motherboard. The subsequent movement of the clamping plate 201 then presses against the side of the computer motherboard through the abutment plate 203. The abutment plate 203 then drives the sliding rod 202 to slide along the interior of the clamping plate 201. During this process, the first spring 204 is compressed. Through the elastic force of the corresponding first spring 204 on the multiple abutments 203, the clamping action on the side of the computer motherboard is completed. During the movement of the abutment plate 203… This will cause the connecting column 205 to move synchronously, and the connecting column 205 will cause one end of the first rotating plate 206 to move, enabling the other end of the first rotating plate 206 to drive the second rotating plate 207 to rotate around the limit rod 209. At the same time, the clamping block 208 will rotate with the end of the second rotating plate 207. Then, when the second hydraulic cylinder 8 outputs to the specified stroke, it will stop outputting. At this time, the abutment plate 203 will be pressed against the side wall of the clamping plate 201. At the same time, the first rotating plate 206 will drive the clamping block 208 to rotate to the maximum angle through the second rotating plate 207. At this time, the bottom of the multiple clamping blocks 208 will be attached to the top of the computer motherboard. When the slide bar 202 slides outward along the inside of the clamping plate 201, its end will press against the end slope of the connecting post 205. Then, after the placement plate 215 is pressed, it will drive the slider 214 to slide along the inner wall of the tension spring 213. During the process, the second slide groove 212 will be stretched. After the slide bar 202 has finished sliding, the placement plate 215 will detach from the bottom of the clamping plate 201, thereby avoiding affecting the subsequent detection process. Through the cooperation of the clamping block 208 and the clamping plate 201, the bottom and top of the computer motherboard can be clamped, and the output distance of the second hydraulic cylinder 8 can be adjusted according to the size of the computer motherboard. Then, the computer motherboard can be automatically clamped in multiple directions.

[0034] Example 2, please refer to Figure 2 , Figure 5 and Figure 6Based on Embodiment 1, in this embodiment, a rotating mechanism 6 is provided at the end of the horizontal plate 5.

[0035] Specifically, the rotating mechanism 6 includes a stop rod 601, and a third sliding groove 602 is provided inside the stop rod 601. A pressing plate 603 is slidably connected to the inner wall of the third sliding groove 602, and a second spring 604 is fixedly connected to the side wall of the pressing plate 603. The end of the second spring 604 that is away from the pressing plate 603 is fixedly connected to the inner wall of the third sliding groove 602. A sliding plate 605 is slidably connected to the inner wall of the first sliding groove 211. A limit frame 606 is fixedly connected to the inner wall of the outer shell 1, and a third spring 607 is fixedly connected to the inner wall of the limit frame 606. The end of the third spring 607 that is away from the limit frame 606 is fixedly connected to the outer wall of the sliding plate 605.

[0036] After the clamping mechanism 2 completes the clamping of the computer motherboard, the first hydraulic cylinder 4 drives the pressure component 14 of its output shaft to press down, applying the pressure specified for the pressure resistance test to the computer motherboard, thereby evaluating the motherboard's resistance to breakage. When the pressure resistance test is completed, the first hydraulic cylinder 4 drives the output shaft to retract and reset, simultaneously moving the abutment rod 601 upwards via the horizontal plate 5, and also moving the second spring 604. Since the end of the sliding plate 605 slides against the side wall of the abutment rod 601, when the abutment rod 601 moves to a certain position, the top of the pressing plate 603 contacts the end of the sliding plate 605, pressing it and causing the sliding plate 605 to rotate. Because the outer wall of the ring 9 is rotatably connected to the inner wall of the groove 10, the rotation of the connecting rod 210 does not affect the second hydraulic cylinder 8. The output shaft controls the distance the connecting rod 210 moves. Then, the sliding plate 605 slides along the inner wall of the limiting frame 606. Through the cooperation of the limiting frame 606 and the first slide groove 211, the position of the sliding plate 605 can be limited to ensure that the sliding plate 605 will not deviate during the movement. At the same time, the third spring 607 will be compressed, and the connecting rod 210 will also drive the clamping plate 201 to rotate synchronously. Since the rotation directions of the two clamping plates 201 are not the same, the two clamping plates 201 drive the two sides of the computer motherboard to rotate, realizing the automatic torsion test after the computer motherboard completes the withstand pressure test. Then, the abutment rod 601 will drive the pressing plate 603 to disengage from the sliding plate 605. At this time, the third spring 607 will perform elastic reset, so that the sliding plate 605 drives the clamping plate 201 to rotate and reset in the opposite direction through the connecting rod 210, completing the torsion test of the computer motherboard and improving the comprehensiveness of the test.

[0037] When the computer motherboard is tested by the pressure assembly 14, the push rod 601 will drive the pressing plate 603 to move downward, and the sliding plate 605 will be limited by the limit bracket 606. Then the inclined surface of the pressing plate 603 will contact the sliding plate 605. Then the pressing plate 603 will slide along the inner wall of the third slide groove 602. During the process, the second spring 604 will be compressed. When the pressing plate 603 is separated from the end of the sliding plate 605, the second spring 604 will drive the pressing plate 603 to slide outward and reset along the inner wall of the third slide groove 602.

[0038] Example 3, please refer to Figure 7-8 Based on Embodiment 2, in this embodiment, the inner wall of the collection cavity 11 is provided with a collection mechanism 12.

[0039] Specifically, the collecting mechanism 12 includes a sealing plate 1201, and a toothed groove 1202 is formed at the bottom of the sealing plate 1201. A gear 1203 is meshed with the inner wall of the toothed groove 1202, and a first fixed rod 1204 is rotatably connected to the center of the gear 1203. A rack 1205 is meshed with the inner wall of the gear teeth of the gear 1203, and a push plate 1206 is fixedly connected to one end of the rack 1205. A pull rope 1207 is fixed to the end of the rack 1205 away from the push plate 1206. A limiting groove 1210 is formed on the side wall of the sealing plate 1201, and a second fixed rod 1209 is slidably connected to the inner wall of the limiting groove 1210. A fourth spring 1211 is fixedly connected to the side wall of the sealing plate 1201. The sidewall is slidably connected to the inner wall of the collecting chamber 11. The end of the first fixing rod 1204 that is away from the gear 1203 is fixedly connected to the inner wall of the collecting chamber 11. The end of the pull rope 1207 that is away from the rack 1205 is fixedly connected to the bottom of the push rod 601. The sidewall of the push plate 1206 is slidably connected to the inner wall of the collecting chamber 11. The end of the second fixing rod 1209 that is away from the limiting groove 1210 is fixedly connected to the inner wall of the collecting chamber 11. The end of the fourth spring 1211 that is away from the limiting groove 1210 is fixedly connected to the inner wall of the collecting chamber 11. A roller 1208 is fixedly installed on the inner wall of the collecting chamber 11. A connecting groove 13 is opened inside the outer shell 1. The outer wall of the push rod 601 is slidably connected to the inner wall of the connecting groove 13.

[0040] When the computer motherboard is tested by the pressure assembly 14, the push rod 601 slides down along the inner wall of the connecting groove 13, which drives one end of the pull rope 1207 to move downward. At this time, the pull rope 1207 will not pull the rack 1205. Then the fourth spring 1211 will return to its original position, causing the two sealing plates 1201 to slide away from each other, thereby opening the inlet of the collection chamber 11. During the process, the tooth groove 1202 will drive the rack 1205 to move through the gear 1203, causing the two push plates 1206 to slide towards each other. After sliding, the two push plates 1206 will stick together. Later, during the performance test of the computer motherboard, some computer motherboards may fail the test, causing the computer motherboard to break or shatter during the test. The broken computer motherboard fragments will fall into the collection chamber 11, which facilitates the removal of the failed motherboards. The tested computer motherboards are collected for subsequent processing. After the test, when the push rod 601 slides upward along the inner wall of the connecting groove 13, it will drive the pull rope 1207 to slide upward from the outer wall of the roller 1208. At the same time, the pull rope 1207 will pull the rack 1205, causing the push plate 1206 to slide the computer motherboard fragments on the side, pushing the computer motherboard fragments to the corner of the collection chamber 11, so that the collection chamber 11 can store more computer motherboard fragments. Meanwhile, the gear 1203 will drive the rack 1205 to slide in the opposite direction, so that the two racks 1205 slide together, thereby closing the inlet of the collection chamber 11, avoiding oxidation or contamination and corrosion of the motherboard fragments inside the collection chamber 11, improving the residual value and recycling rate of the motherboard fragments. The sliding of the second fixing rod 1209 inside the limiting groove 1210 can ensure that the sliding process of the sealing plate 1201 is more stable.

[0041] The working principle of this invention is:

[0042] The computer motherboard to be tested is placed on the end surfaces of multiple placement plates 215 that are close to each other. Then, according to the size of the computer motherboard, a command is issued to the second hydraulic cylinder 8, causing the second hydraulic cylinder 8 to output to a specified stroke. Then, the second hydraulic cylinder 8 drives the output shaft ring 9 to output. Then, the ring 9 drives the connecting rod 210 to move synchronously through the circular groove 10. During this process, the outer wall of the connecting rod 210 will slide through the side wall of the outer casing 1 and into it, moving relative to each other through the two clamping plates 201. Then, the clamping plates 201 move in the following process. The abutment 203 presses against the side of the computer motherboard, causing the slide bar 202 to slide along the inside of the clamping plate 201. During this process, the first spring 204 is compressed. The multiple abutments 203 are subjected to the corresponding elastic force of the first spring 204, thus clamping the side of the computer motherboard. As the abutment 203 moves, it drives the connecting post 205 to move synchronously. Simultaneously, the connecting post 205 drives one end of the first rotating plate 206 to move, enabling the other end of the first rotating plate 206 to drive the second rotating plate 201. 7. The limit rod 209 rotates at an angle, and the clamping block 208 rotates with the end of the second rotating plate 207. Then, the output of the second hydraulic cylinder 8 stops when it reaches the specified stroke. At this time, the abutment plate 203 will be pressed against the side wall of the clamping plate 201. At the same time, the first rotating plate 206 will drive the clamping block 208 to rotate to the maximum angle through the second rotating plate 207. At this time, the bottom of the multiple clamping blocks 208 will be pressed against the top of the computer motherboard. When the slide rod 202 slides outward along the inside of the clamping plate 201, its end will press against the connecting post 205. The end bevel is pressed, and then the placement plate 215 is pressed and will drive the slider 214 to slide along the inner wall of the tension spring 213. During the process, the second slide groove 212 will be stretched. After the slide bar 202 has slid, the placement plate 215 will be disengaged from the bottom of the clamping plate 201, thereby avoiding affecting the subsequent detection process. Through the cooperation of the clamping block 208 and the clamping plate 201, the bottom and top of the computer motherboard can be clamped. The output distance of the second hydraulic cylinder 8 can be adjusted according to the size of the computer motherboard, and then the computer motherboard can be automatically clamped in multiple directions.

[0043] The horizontal plate 5 drives the abutment rod 601 to move upward synchronously, which in turn drives the second spring 604 to move. Since the end of the sliding plate 605 slides against the side wall of the abutment rod 601, when the abutment rod 601 moves to a certain position, the top of the pressing plate 603 will contact the end of the sliding plate 605, and then press it, causing the sliding plate 605 to be compressed, thereby driving the connecting rod 210 to rotate. Since the outer wall of the ring 9 is rotatably connected to the inner wall of the circular groove 10, the rotation of the connecting rod 210 will not affect the output shaft of the second hydraulic cylinder 8 to control the distance of movement of the connecting rod 210. Then, the sliding plate 605 will slide along the inner wall of the limiting frame 606. Through the cooperation of the limiting frame 606 and the first sliding groove 211, the position of the sliding plate 605 can be limited to ensure that the sliding plate 605 will not deviate during the movement. At the same time, the third spring 607 will be compressed, and the connecting rod 210 will also drive the clamping plate 201 to rotate synchronously. Since the rotation directions of the two clamping plates 201 are not the same, the two clamping plates 201 drive the two sides of the computer motherboard to rotate, realizing the automatic torsion test after the computer motherboard completes the withstand pressure test.

[0044] During the performance testing of computer motherboards, some motherboards may fail the test, causing them to break or shatter during the test. The broken motherboard fragments will then fall into the collection chamber 11, facilitating the collection of the failed motherboards for subsequent processing. After the test is completed, when the push rod 601 slides upward along the inner wall of the connecting groove 13, it will cause the pull rope 1207 to slide upward from the outer wall of the roller 1208. At the same time, the pull rope 1207 will pull the rack 1205, causing the push plate 1206 to slide the motherboard fragments on the side, pushing the motherboard fragments to the corner of the collection chamber 11, allowing the collection chamber 11 to store more motherboard fragments.

[0045] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part.
