Description

Technical Field

[0001] The present application relates to the technical field of electronic technology socket testing, and in particular to a socket testing device for electronic technology research in a physics department. Background Art

[0002] The socket test device of the Department of Physics Electronic Technology is usually used to ensure the interface quality and performance in electronic equipment, thereby improving the efficiency and accuracy of electronic equipment interface testing, and reducing manual operations through automation and integration methods to ensure the quality of the interface.

[0003] For example, a socket testing device for Beidou navigation chip with publication number CN118376902A relates to the field of socket testing technology, including a supporting mechanism, a conveying mechanism, a limiting mechanism and a testing mechanism, wherein the supporting mechanism includes a bearing platform and a supporting platform located at the bottom of the bearing platform; the conveying mechanism is arranged on the bearing platform and has a first state of driving multiple socket bodies to move and a second state of stopping driving the socket bodies to move; when the conveying mechanism is in the first state, the limiting mechanism releases the clamping limit of the socket body, and when the conveying mechanism is in the second state, the limiting mechanism starts to work to limit and clamp the socket body; when the limiting mechanism starts to work to limit and clamp the socket body, the testing mechanism starts to work and automatically performs a socket test on the clamped socket body, and when the limiting mechanism releases the limit clamping of the socket body, the testing mechanism stops working, thereby solving the problem of low testing efficiency during the test process, thereby affecting the test progress.

[0004] However, the above-mentioned prior art still has some defects when it comes to socket testing: 1. In the process of the conveying mechanism conveying the socket body to the limiting mechanism, the above-mentioned patent application needs to ensure that the spacing between the socket bodies and the position of the socket bodies on the conveying mechanism remain fixed. However, the intermittent movement of the conveying mechanism may cause the socket body to slide under inertia, and the limiting mechanism only clamps and limits the two sides of the socket body. Therefore, in the second state, the socket body may not be directly under the detection head of the test mechanism, and further, the limiting mechanism on both sides cannot ensure that the detection head of the test mechanism can be accurately inserted into the socket body for detection, which will lead to an increase in the error rate of the socket test.

[0005] 2. In the second state of the above patent application, under the action of the torsion spring, the second pulley rotates and drives the belt to rotate. Since the first pulley remains stationary under the action of the ratchet, the belt will rub against the first pulley, which may cause damage to the belt and loss of the first pulley, thereby increasing the cost of the device.

[0006] Based on this, under the above-mentioned viewpoints, the existing technology for electronic technology socket testing still has room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0047] The following is combined with Figures 1 to 16 This application is described in further detail.

[0048] The embodiment of the present application discloses a socket testing device for electronic technology research in the Department of Physics, which can ensure that the sample 100 to be tested is completely limited, thereby avoiding a reduction in the accuracy of the socket test due to incomplete limitation of the sample 100 to be tested.

[0049] Embodiment 1:

[0050] Reference Figure 1 , Figure 2 and Figure 4 A socket testing device for electronic technology research in the Department of Physics includes a transmission mechanism 1, which includes a transmission belt 11 and a transmission roller 12. Testing mechanisms 2 are arranged on both sides of the transmission belt 11, and a second limit frame 4 and a first limit frame 3 are arranged along the moving direction of the transmission belt 11.

[0051] The testing mechanism 2 includes a side plate 21, and a plurality of first guide rails 22 extending along the width direction of the conveyor belt 11 are installed on the side of the side plate 21 close to the conveyor belt 11, and second guide rails 23 extending along the length direction of the conveyor belt 11 are installed between the first guide rails 22, and a plurality of third guide rails 24 are installed on the second guide rails 23, and a test block 25 is installed on the third guide rail 24, and a socket test head 26 is clamped on the test block 25.

[0052] The first limiting frame 3 includes a lifting plate 31, which is used to limit and release the sample 100 to be tested. Limiting rods 32 are arranged at both ends of the lifting plate 31 along its height direction, which can be used for lifting and lowering the lifting plate 31. Limiting plates 33 are installed on the top of the limiting rods 32. Rack holes 34 are arranged at both ends of the lifting plate 31, and straight plate racks 35 are also arranged at both ends of the lifting plate 31.

[0053] In specific operation, the device has three states when performing the socket test. The first state is the conveying state. At this time, the conveyor belt 11 runs and conveys the sample 100 to be tested, and drives the lifting plate 31 to descend. Because the lifting plate 31 of the first limiting rack 3 is lower than the height of the second limiting rack 4 from the conveyor belt 11, when the lifting plate 31 of the first limiting rack 3 can limit the sample 100 to be tested, the second limiting rack 4 can also allow the sample 100 to be tested to pass. Until the sample 100 to be tested contacts the lifting plate 31 of the first limiting rack 3, the lifting plate 31 of the second limiting rack 4 also completes the limiting of the sample 100 to be tested, thereby ensuring that the sample 100 to be tested can be The conveyor belt 11 stops running, and the testing mechanism 2 tests the sample 100 socket. After the test is completed, as the testing mechanism 2 moves away from the sample 100 socket, the height between the lifting plate 31 and the conveyor belt 11 rises to a state where the sample 100 can pass. The third state is the output state. At this time, the conveyor belt 11 starts to run, but the lifting plate 31 does not start to descend with the operation of the conveyor belt 11. The tested sample 100 enters the collecting device (not shown in the figure) under the drive of the conveyor belt 11 for collection. After the sample 100 enters the collecting device, the device re-enters the first state.

[0054] Among them, the first limit frame 3 and the second limit frame 4 are basically the same in structure, but the first limit frame 3 remains fixed, while the second limit frame 4 can move along the moving direction of the conveyor belt 11, so as to better limit the sample 100 to be tested. In the specific implementation process, before the device is operated, the third guide rail 24 and the test block 25 with the corresponding number of sockets are added or reduced on the second guide rail 23 according to the number of sockets on the sample 100 to be tested, and then the matching socket test head 26 is installed on the test block 25 according to the shape of the socket of the sample 100 to be tested, and the position of the third guide rail 24 and the test block 25 is adjusted according to the position of the socket, and finally according to The length of the sample 100 to be tested adjusts the position of the second limit rack 4. After the socket test of the sample 100 is completed, the first limit rack 3 and the lifting plate 31 of the second limit rack 4 are raised, and the conveyor belt 11 is started. The tested sample 100 enters the collection device along the conveyor belt 11, and the next sample 100 to be tested enters the socket test area. Then, when testing the socket of a certain type of sample 100, the device can ensure accurate limiting of the sample 100 to be tested and can realize automatic socket testing of this type of sample 100. When it is necessary to change to another type of sample 100 for socket testing, just repeat the above steps.

[0055] Reference Figure 6 Before the test starts, the lifting plates 31 of the first limit rack 3 and the second limit rack 4 are both in a raised state, and it is ensured that the distance between the bottom of the lifting plate 31 and the conveyor belt 11 is greater than the height of the sample 100 to be tested, so that the sample 100 can smoothly enter the socket test area. In addition, a buffer spring 251 is provided on the test block 25 to ensure that when the socket test head 26 is inserted into the socket, the impact force generated by the collision will not cause damage to the socket and the socket test head 26, and the socket test head 26 has a built-in signal sensor (not shown in the figure), which can send the test results to The terminal tester (not shown in the figure) can then know the quality of the socket. During the specific implementation process, when the device tests the sample 100 to be tested, the first limit rack 3 and the second limit rack 4 limit the sample 100 front and rear, and then the second guide rail 23 slides toward the direction of the sample 100 to be tested, and at the same time drives the socket test head 26 to slide. After the socket test head 26 is inserted into the socket of the sample 100, the signal sensor of the test block 25 conveys the quality information of the socket to the terminal tester, and then the inferior socket can be processed to avoid the inferior socket from affecting the use of the sample 100.

[0056] Reference Figure 2 and Figure 3 A linkage rod 36 is passed through the middle of the limit plate 33 and is rotatably installed through a bearing. A linkage bevel gear 37 is provided at one end of the linkage rod 36 away from the lifting plate 31, and a one-way gear 38 is provided at one end of the linkage rod 36 close to the lifting plate 31, that is, a gear that can only rotate in one direction.

[0057] Support frames 39 are provided at both ends of the top of the limiting plate 33 , and a rotating rod 310 is rotatably mounted between the support frames 39 via a bearing. A driving bevel gear 311 meshing with the linkage bevel gear 37 is mounted on the rotating rod 310 .

[0058] During the specific implementation process, the rotating rod 310 drives the driving bevel gear 311 to rotate when it rotates, and the driving bevel gear 311 engages in transmission to drive the linkage bevel gear 37 to rotate, and then the linkage bevel gear 37 drives the linkage rod 36 to rotate, and the linkage rod 36 simultaneously drives the one-way gear 38 to rotate, thereby realizing the lowering of the lifting plate 31. In addition, the one-way gear 38 can also ensure that the one-way gear 38 will not rotate during the rising process of the lifting plate 31, thereby ensuring that the rotating rod 310 will not rotate with the rising of the lifting plate 31, thereby avoiding damage to the device due to rotation.

[0059] Reference Figure 7 and Figure 8 In order to allow the rotating rod 310 to rotate intermittently and thus allow the lifting plate 31 to intermittently repeat the descending process, a half gear 13 is installed on the driving roller 12 close to the first limiting frame 3.

[0060] The first limiting frame 3 also includes a linkage shaft 312, on which a first linkage gear 313 meshing with the half gear 13 is installed. A linkage shaft 312 is provided at one end of the first linkage gear 313 away from the transmission belt 11, and the linkage shaft 312 is connected to the rotating rod 310 through a belt transmission.

[0061] During the specific implementation process, when the device is in the conveying state, under external drive (not shown in the figure), the transmission roller 12 rotates and drives the half gear 13 to rotate. The gear part of the half gear 13 drives the first linkage gear 313 to rotate through meshing transmission, and then the first linkage gear 313 drives the linkage shaft 312 to rotate, and the linkage shaft 312 drives the rotating rod 310 to rotate through belt transmission, so that the lifting plate 31 starts to descend on the limiting rod 32 and limits the sample 100 to be tested; when the device is in the limiting state, the external drive stops running. At this time, the transmission roller 12 is in a stationary state. The lifting plate 31 also remains stationary to perform the limiting function. After the test is completed, the lifting plate 31 begins to rise as the test device is pulled out; when the device is in the output state, the gearless part of the half gear 13 just rotates to the meshing position with the first linkage gear 313. At this time, the transmission belt 11 runs to drive the sample 100 that has completed the socket test into the collection device, while the first limiting rack 3 and the second limiting rack 4 remain stationary. After the sample 100 enters the collection device, the meshing position of the half gear 13 and the first linkage gear 313 runs to the geared part again, thereby re-entering the conveying state.

[0062] Reference Fig.10 The one-way gear 38 includes a gear tooth 314 and a wheel body 315 . The gear tooth 314 includes a telescopic plate 3141 and a sliding plate 3142 . One end of the telescopic plate 3141 is hinged to the wheel body 315 , and one end of the sliding plate 3142 is also hinged to the wheel body 315 .

[0063] A first sliding groove 3143 is provided on one side of the sliding plate 3142 close to the telescopic plate 3141, and one end of the telescopic plate 3141 away from the wheel body 315 is slidably connected to the first sliding groove 3143, and a first reset spring 3144 is installed between the end of the telescopic plate 3141 away from the wheel body 315 and the side of the first sliding groove 3143 close to the wheel body 315, which can reset the telescopic plate 3141 and enable the one-way gear 38 to better complete the meshing transmission task of the next cycle.

[0064] The first resetting spring 3144 resets the telescopic plate 3141 and the second resetting spring 3142, so that the second resetting spring 3142 can be rotated to rotate the second gear 3140, and the second resetting spring 3144 can be rotated to rotate the second gear 3140.

[0065] Reference Fig. 9 In order to enable the one-way gear 38 to play a role of meshing transmission when actively rotating, the gear teeth 314 are provided with holes in the corresponding part of the wheel body 315.

[0066] A magnet ring 3151 is provided inside the wheel body 315, and the magnet ring 3151 is fixedly connected to the linkage rod 36. A second sliding groove 3152 corresponding to the holes is opened between the magnet ring 3151 and the gear teeth 314, and a permanent magnet sliding block 3153 is slidably installed in the second sliding groove 3152. A second reset spring 3154 is installed between the permanent magnet sliding block 3153 and the magnet ring 3151, which can reset the permanent magnet sliding block 3153 so that the one-way gear 38 will not rotate when it is in the driven position. One end of the second reset spring 3154 is connected to the permanent magnet sliding block 3153, and the other end is connected to the magnet ring 3151.

[0067] Among them, the magnet ring 3151 is magnetic when it is powered on, and loses its magnetism when it is powered off, and the magnet ring 3151 repels the permanent magnet sliding block 3153. In the specific implementation process, when the linkage rod 36 drives the one-way gear 38 to actively rotate, the magnet ring 3151 is powered on, and the magnet ring 3151 with magnetism pushes the permanent magnet sliding block 3153 away through the principle of like repels like, so that it slides out of the hole of the wheel body 315 through the second sliding groove 3152, and clamps the telescopic plate 3141 and the sliding plate 3142. At this time, the telescopic plate The gear tooth 314 composed of 3141 and the sliding plate 3142 has a meshing transmission function, and can transmit other gears meshing therewith. When the one-way gear 38 stops transmitting, the magnet ring 3151 is powered off, and the permanent magnet sliding block 3153 is reset under the action of the second reset spring 3154. At this time, the gear tooth 314 composed of the telescopic plate 3141 and the sliding plate 3142 does not have a meshing transmission function, so when the one-way gear 38 is in the driven position, it can remain stationary under the rotation of other gears meshing therewith.

[0068] Reference Figure 2 , Figure 5 and Fig.11 In order to allow the lifting plate 31 to descend when the one-way gear 38 actively rotates, a moving block 316 is provided in the middle of the lifting plate 31 near the linkage rod 36. A threaded rod 317 runs through the middle of the moving block 316 and is rotatably connected to it by a thread. The top of the threaded rod 317 is rotatably mounted on the limit plate 33 through a bearing, and a second linkage gear 318 meshing with the one-way gear 38 is installed on the threaded rod 317.

[0069] A ratchet 319 is rotatably mounted on the threaded rod 317 via a bearing, and an electromagnetic ring 320 is mounted on the threaded rod 317 at a position corresponding to the ratchet 319 , a permanent magnetic pawl 321 is hinged on the electromagnetic ring 320 , and a third reset spring 322 is installed between the end of the permanent magnetic pawl 321 away from the hinge point and the electromagnetic ring 320 .

[0070] Among them, the electromagnetic ring 320 is energized when the threaded rod 317 rotates, and the electromagnetic ring 320 is de-energized when the threaded rod 317 stops rotating. The electromagnetic ring 320 is magnetic when it is energized, and it is not magnetic when it is de-energized. Before the operation of the device, the permanent magnetic pawl 321 is not in contact with the ratchet 319. In the specific implementation process, when the one-way gear 38 actively rotates, it drives the second linkage gear 318 to rotate through meshing transmission, and then the second linkage gear 318 drives the threaded rod 317 to rotate. At this time, since the electromagnetic ring 320 is magnetic and the principle of like charges repel each other, the permanent magnetic pawl 321 is pushed toward the ratchet 319 and engaged with the ratchet 319, When the threaded rod 317 rotates, it can drive the ratchet 319 to rotate. In addition, since the moving block 316 is connected to the threaded rod 317 through a threaded rotation, the moving block 316 starts to descend with the lifting plate 31. After the sample 100 to be tested completely enters the test area and is completely limited by the lifting plate 31, the external drive stops running, and the threaded rod 317 and the moving block 316 also stop rotating, and then the lifting plate 31 no longer descends. At the same time, the electromagnetic ring 320 is powered off and loses its magnetism. The permanent magnetic pawl 321 can therefore be reset under the action of the third reset spring 322 and no longer engages with the ratchet 319. Subsequently, the socket of the sample 100 to be tested can be tested.

[0071] Reference Figure 4 and Figure 5 In order to prevent the straight plate racks 35 at both ends of the lifting plate 31 from meshing with other gears during the descent of the lifting plate 31, rope threading plates 323 are symmetrically installed on both sides of the lifting plate 31 along its length direction, and a rope threading hole 324 is provided in the center of the rope threading plate 323. A plurality of fourth return springs 325 are installed between the rope threading plate 323 and the straight plate racks 35.

[0072] A steel wire rope 326 is installed between the ratchet wheel 319 and the straight plate racks 35 at both ends of the lifting plate 31.

[0073] Among them, the straight plate rack 35 is engaged with the rack hole 34, and when the straight plate rack 35 is completely leaked out of the rack hole 34, the wire rope 326 is just in a straightened state. During the specific implementation process, when the threaded rod 317 rotates, the ratchet 319 rotates along with the threaded rod 317, and at the same time, the wire rope 326 is rolled on the ratchet 319. At this time, the straight plate rack 35 begins to slide toward the threaded rod 317, so that the straight plate rack 35 will not engage with any gear during the descent process. When the threaded rod 317 stops rotating, under the action of the fourth reset spring 325, the straight plate rack 35 begins to reset and synchronously drives the wire rope 326 to move. Since the electromagnetic ring 320 is powered off at this time, the permanent magnetic pawl 321 is not engaged with the ratchet 319. The ratchet 319 rotates under the action of the wire rope 326 and will not drive the threaded rod 317 to rotate, thereby avoiding damage to the device caused by the rotation of the threaded rod 317.

[0074] Reference Fig.12 In order to allow the lifting plate 31 to rise after the socket test is completed so that the sample 100 can pass, the first limiting frame 3 includes a support plate 327, on which a third linkage gear 328 and a fourth linkage gear 329 meshingly connected to the third linkage gear 328 are installed, and the third linkage gear 328 is meshingly connected to the straight plate rack 35.

[0075] During the specific implementation process, the fourth linkage gear 329 drives the third linkage gear 328 to rotate through the gear meshing transmission when it rotates, and the third linkage gear 328 drives the straight plate rack 35 upward through the meshing transmission, so that the lifting plate 31 can rise. When the lifting plate 31 rises to a height between it and the conveyor belt 11 for the sample 100 that has completed the test to pass, the fourth linkage gear 329 stops rotating, and then the lifting plate 31 stops moving.

[0076] Reference Fig.12 and Fig.13 In order to rotate the fourth linkage gear 329 and thereby allow the lifting plate 31 to rise, support blocks 231 are installed at both ends of the second guide rail 23, and a one-way rack plate 232 is installed on the support block 231, that is, it can only mesh with the gear in one direction.

[0077] The one-way rack plate 232 includes a trapezoidal block 2321 , a straight plate 2322 and a tension spring 2323 . The short side of the trapezoidal block 2321 is hinged to the straight plate 2322 , and a tension spring 2323 is installed between the short side of the trapezoidal block 2321 and the straight plate 2322 .

[0078] Among them, the support block 231 and the second guide rail 23 close to the second limit frame 4 are fixed together by using bolts and nuts as fasteners, so the support block 231 can be disassembled, and then the third guide rail 24 can be added or subtracted on the second guide rail 23 according to the number of sockets of the sample 100 to be tested. After the addition or subtraction of the third guide rail 24 is completed, the support block 231 is reinstalled. In addition, a telescopic structure is provided between the support block 231 and its corresponding support plate 327 to facilitate the adjustment of the distance of the second limit frame 4. During the specific implementation process, in the test state, the second guide rail 23 drives the one-way rack plate 232 slides toward the direction of the sample 100 to be tested. When the fourth linkage gear 329 contacts the rack of the one-way rack plate 232, the trapezoidal block 2321 starts to rotate. At this time, the fourth linkage gear 329 cannot mesh with the one-way rack plate 232. After contacting the fourth linkage gear 329, the trapezoidal block 2321 is reset under the action of the tension spring 2323. When the test of the sample 100 is completed, the second guide rail 23 drives the one-way rack plate 232 away from the sample 100. At this time, the one-way rack plate 232 can mesh with the fourth linkage gear 329 for transmission, thereby causing the lifting plate 31 to rise.

[0079] Embodiment 2:

[0080] Reference Fig.16 A limiting plate 33 and a rotating rod 310 are also provided on the second limiting frame 4. The two limiting plates 33 are hinged with a hinge rod 330, and the two hinge rods 330 are hinged with a hinge shaft at one end away from the limiting plate 33. A central axis rod 331 is rotatably installed in the middle of the hinge shaft through a bearing, and the two rotating rods 310 and the central axis rod 331 are connected by a belt drive.

[0081] Reference Fig.14, wherein a pulley 332 is installed at the bottom of the support plate 327 of the second limit frame 4, and the limit rod 32 of the second limit frame 4 is slidably installed in the limit groove 333 extending along the moving direction of the conveyor belt 11. In the specific implementation process, when it is necessary to adjust the distance between the second limit frame 4 and the first limit frame 3 according to the length of the sample 100 to be tested, the pulley 332 and the limit rod 32 of the support plate 327 are moved, and the movement of the second limit frame 4 can be realized. As the distance between the second limit frame 4 and the first limit frame 3 increases or decreases, the hinge The connecting rod 330 also rotates together, and at the same time, the hinge shaft and the central axis rod 331 also rise or fall with the rotation of the hinge rod 330, so that when the distance between the second limit frame 4 and the first limit frame 3 changes, the belt connecting the rotating rod 310 of the two can always remain straightened under the action of the rising or falling of the central axis rod 331, and will not be tightened or relaxed, so as to avoid the failure of the belt transmission between the rotating rods 310 to complete, resulting in the failure of the limit of the sample 100 to be tested, and then the failure of the socket test to complete.

[0082] Reference Fig.15 A plurality of telescopic spring rods 233 are installed on the side of the second guide rail 23 close to the conveyor belt 11, and a clamping plate 234 is installed on the end of the telescopic spring rods 233 away from the second guide rail 23, and the telescopic spring rods 233 do not affect the sliding of the third guide rail 24 on the second guide rail 23. In the test state, the telescopic spring rods 233 move together with the second guide rail 23 in the direction of the sample 100 to be tested. At this time, the clamping plate 234 can limit the two sides of the sample 100 to be tested, and then the device can achieve comprehensive limiting of the sample 100 to be tested, ensuring that the sample 100 can maintain a stable state during the socket test. After the test is completed, the clamping plate 234 moves away from the sample 100 together with the second guide rail 23, and the lifting plate 31 also rises together, and the limit of the sample 100 that has been tested is released, and then it can be output and collected.

[0083] Embodiment three:

[0084] The quality of the socket can be judged based on the strength of the electronic signal generated when the socket test head 26 is inserted into the socket. After the socket test head 26 is inserted into the socket of sample 100, different signal sensors will feed back the electronic signal of the corresponding socket to the terminal tester. On the terminal tester, the quality of the corresponding socket is judged based on the strength of the electronic signal transmitted by each socket test head 26, and then the socket with weak electronic signal is repaired or adjusted, and no adjustment is made to the socket with strong electronic signal, thereby avoiding the influence of inferior socket on the use or research of sample 100 and ensuring the effectiveness of the use of sample 100 socket.

[0085] The implementation principle of the present invention is:

[0086] 1: The first state is the conveying state, at which the conveyor belt 11 runs and conveys the sample 100 to be tested, and at the same time drives the lifting plate 31 to descend, because the lifting plate 31 of the first limiting rack 3 is lower than the height of the second limiting rack 4 from the conveyor belt 11, so when the lifting plate 31 of the first limiting rack 3 can limit the sample 100 to be tested, the second limiting rack 4 can still allow the sample 100 to be tested to pass, until the sample 100 to be tested contacts the lifting plate 31 of the first limiting rack 3, the lifting plate 31 of the second limiting rack 4 also completes the limiting of the sample 100 to be tested, thereby ensuring that the sample 100 to be tested can be accurately limited.

[0087] 2: The second state is the test state. In the test state, the conveyor belt 11 stops running, and the testing mechanism 2 tests the socket of the sample 100. After the test is completed, as the testing mechanism 2 moves away from the socket of the sample 100, the lifting plate 31 rises to a height above the conveyor belt 11 to allow the sample 100 to pass.

[0088] 3: The third state is the output state. At this time, the conveyor belt 11 starts to run, but the lifting plate 31 does not start to descend along with the running of the conveyor belt 11. The tested sample 100 enters the collecting device (not shown in the figure) under the drive of the conveyor belt 11 for collection. After the sample 100 enters the collecting device, the device re-enters the first state.
