Description

Technical Field

[0001] This application relates to the field of testing technologies, and particularly to a plug and unplug testing device. Background Art

[0002] An expansion card is an electronic component inserted into an expansion slot on the motherboard of an electronic device, enabling the expansion of specific functions and the improvement of performance of the electronic device.

[0003] The expansion card needs to be inserted into the expansion slot or pulled out from the expansion slot multiple times for plug and unplug testing to detect whether the physical connection between the gold fingers of the expansion card and the contacts of the expansion slot is stable. However, the plug and unplug testing of the expansion card relies on manual labor, and there are cases where the expansion card is not inserted in place, resulting in low accuracy of the plug and unplug testing and low testing efficiency. Summary of the Invention

[0004] This application provides a plug and unplug testing device to at least solve the problems of low efficiency and low accuracy of the plug and unplug testing of the expansion card in the related art, and achieve the effect of improving the efficiency and accuracy of the plug and unplug testing of the expansion card.

[0005] This application provides a plug and unplug testing device, including: a mounting mechanism configured to position an electronic component, where an expansion slot for accommodating the expansion card is provided on the electronic component; a picking and placing mechanism that expands and contracts in a first direction, configured to insert the expansion card into the expansion slot and release the expansion card or clamp the expansion card and pull the expansion card out of the expansion slot; and a pressing mechanism configured to, when the expansion card is inserted into the expansion slot, press the expansion card in a direction close to the expansion slot, and when the expansion card is pulled out of the expansion slot, separate the pressing mechanism from the expansion card and allow the expansion card to be pulled out of the expansion slot.

[0006] Through this application, when performing plug and unplug testing on the expansion card, the electronic component is positioned on the mounting mechanism. Since the picking and placing mechanism expands and contracts in the first direction, the picking and placing mechanism can insert the expansion card into the expansion slot and release it. Then, the pressing mechanism presses the expansion card in a direction close to the expansion slot, making the expansion card inserted in place and improving the accuracy of the plug and unplug testing. Subsequently, when pulling the expansion card out of the expansion slot, the pressing mechanism separates from the expansion card, enabling the picking and placing mechanism to clamp the expansion card and pull the expansion card out of the expansion slot, thus automatically completing a single plug and unplug test of the expansion card. After multiple cycles, multiple plug and unplug tests of the expansion card are automatically completed, saving manpower. Therefore, the technical problems of low efficiency and low accuracy of the plug and unplug testing of the expansion card can be solved, and the technical effect of improving the efficiency and accuracy of the plug and unplug testing of the expansion card can be achieved.

[0017] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0018] Before the expansion card is put on the market, insertion and extraction tests and performance tests need to be carried out. During the insertion and extraction test, the expansion card is inserted into or pulled out of the expansion slot manually to complete the insertion and extraction test, and it is detected whether the physical connection between the gold fingers of the expansion card and the contacts of the expansion slot is stable. However, relying on manual operation for the insertion and extraction test, there is a situation where the expansion card is not inserted in place, resulting in low accuracy and low test efficiency of the insertion and extraction test.

[0019] The present application provides an insertion and extraction test device, and the insertion and extraction test device will be described in detail in combination with the structure and working principle of the insertion and extraction test device. The electronic device includes, but is not limited to, any computer, server, network device, storage device, etc. that uses an expansion card.

[0020] Refer toFigure 1 As shown in the figure, the plugging and unplugging test device includes an installation mechanism 1, a picking and placing mechanism 2, and a pressing mechanism 3. The installation mechanism 1 is configured to position the electronic component 7, and an expansion slot 71 for accommodating the expansion card 72 is provided on the electronic component 7. The picking and placing mechanism 2 telescopically moves in the first direction and is configured to insert the expansion card 72 into the expansion slot 71 and release the expansion card 72, or pick up the expansion card 72 and pull out the expansion card 72 from the expansion slot 71. The pressing mechanism 3 is configured to press the expansion card 72 in the direction close to the expansion slot 71 when the expansion card 72 is inserted into the expansion slot 71, and separate from the expansion card 72 and allow the expansion card 72 to be pulled out from the expansion slot 71 when the expansion card 72 is pulled out from the expansion slot 71.

[0021] Specifically, the electronic component 7 may be a main board, and an expansion slot 71 for accommodating the expansion card 72 is provided on the electronic component 7. Contacts for physically connecting with the gold fingers of the expansion card 72 are provided in the expansion slot 71. The expansion card 72 is generally inserted into the expansion slot 71 on the main board for use. The expansion card 72 needs to be tested for plugging and unplugging to detect whether the physical connection performance between the gold fingers of the expansion card 72 and the contacts in the expansion slot 71 is stable.

[0022] Specifically, the installation mechanism 1 includes, but is not limited to, a base frame 11 and a positioning component, to place the electronic component 7 on the base frame 11 and fix it to the base frame 11 through the positioning component, so as to position the electronic component 7 and prevent the electronic component 7 from moving relative to the base frame 11. The positioning component includes, but is not limited to, detachable connectors such as bolts and snap components, to facilitate the disassembly and replacement of the positioning component.

[0023] It should be noted that. The first direction ( Figure 1 the vertical direction in the figure) can represent the extending direction of the expansion slot 71. The picking and placing mechanism 2 is provided at the port of the expansion slot 71. The picking and placing mechanism 2 includes, but is not limited to, a cylinder and a clamping component 22, a hydraulic cylinder and a clamping component 22, a robotic arm, etc., which are specifically determined according to actual needs. The picking and placing mechanism 2 is configured to pick up or release the expansion card 72, and telescopically move in the first direction to drive the expansion card 72 to move in the first direction to insert into the expansion slot 71 or move out from the expansion slot 71.

[0024] Further, when performing the plugging and unplugging test on the expansion card 72, the picking and placing mechanism 2 clamps the expansion card 72 and moves it towards the expansion slot 71 to insert the expansion card 72 into the expansion slot 71 and release the expansion card 72. Then, the pressing mechanism 3 presses the expansion card 72 towards the expansion slot 71, pushing the expansion card 72 further into the expansion slot 71 to ensure that the expansion card 72 is inserted in place, avoiding the situation of abnormal testing caused by the incomplete insertion of the expansion card 72, thereby improving the accuracy of the plugging and unplugging test. After the expansion card 72 has been located in the expansion slot 71 for a preset time, the pressing mechanism 3 moves away from the expansion card 72 to separate from the expansion card 72, thereby allowing the picking and placing mechanism 2 to clamp the expansion card 72 and pull out the expansion card 72 from the expansion slot 71, thus automatically completing a single plugging and unplugging test. By repeating this process multiple times, multiple plugging and unplugging tests of the expansion card 72 can be automatically completed. Among them, the preset time can be 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, etc., which is specifically determined according to actual needs.

[0025] In such an embodiment, when performing the plugging and unplugging test on the expansion card 72, the picking and placing mechanism 2 can automatically insert the expansion card 72 into the expansion slot 71 or pull out the expansion card 72 from the expansion slot 71. At the same time, after the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71 and releases the expansion card 72, the pressing mechanism 3 further inserts the expansion card 72 into the expansion slot 71 to ensure that the expansion card 72 is inserted in place, avoiding the situation of abnormal testing caused by the incomplete insertion of the expansion card 72, thereby improving the accuracy of the plugging and unplugging test. By the cooperation of the picking and placing mechanism 2 and the pressing mechanism 3, multiple plugging and unplugging tests of the expansion card 72 can be automatically completed, which can save manpower and improve the degree of automation. In this way, the technical problems of low efficiency and low accuracy of the plugging and unplugging test of the expansion card 72 can be solved, and the technical effect of improving the efficiency and accuracy of the plugging and unplugging test of the expansion card 72 can be achieved.

[0026] In some exemplary embodiments, referring to Figure 1 and Figure 2 as shown, the mounting mechanism 1 includes a base frame 11, a mounting portion 12, and a positioning portion 13. The base frame 11 is configured to place the electronic component 7. The mounting portion 12 is provided on the base frame 11. The positioning portion 13 is rotatably provided on the mounting portion 12 and is configured to press the electronic component 7 against the base frame 11 to prevent the electronic component 7 from moving relative to the base frame 11.

[0027] Specifically, referring to Figure 1As shown, the base frame 11 includes a base platform and a support frame. The base platform is a plate-like structure and is placed horizontally to place the electronic component 7. The support frame is arranged on the base platform to install the pick-and-place mechanism 2 and the pressing mechanism 3. The mounting portion 12 is arranged vertically. The mounting portion 12 can be a mounting column or a bolt. The positioning portion 13 is provided with a mounting hole for the mounting portion 12 to pass through, and the upper and lower positions of the positioning portion 13 are limited by a nut so that the positioning portion 13 can rotate relative to the mounting portion 12. The positioning portion 13 can be a spring sheet with a certain elasticity. One end of the positioning portion 13 away from the mounting portion 12 abuts against the side of the electronic component 7 away from the base platform to apply an external force to the electronic component 7 in the direction close to the base platform to position the electronic component 7 and prevent the electronic component 7 from moving relative to the base frame 11. The operation is convenient and the electronic component 7 can be disassembled and replaced.

[0028] It is understandable that the number of the mounting parts 12 and the positioning parts 13 is the same and they are used in conjunction with each other. Four mounting parts 12 and positioning parts 13 are provided, and they are respectively provided at the corners of the electronic component 7. In this way, the external force of the mounting mechanism 1 on the electronic component 7 is more balanced, and the stability of the positioning of the electronic component 7 is further improved. It is understandable that the number of the mounting parts 12 and the positioning parts 13 can also be one, two, three, four, five or six, etc., which is specifically determined according to the volume of the electronic component 7.

[0029] In some exemplary embodiments, referring to Figure 1 As shown, the pick-and-place mechanism 2 includes a telescopic component 21 and a clamping component 22. The telescopic component 21 is telescopic in a first direction to move the expansion card 72 toward or away from the expansion slot 71. The clamping component 22 is disposed at one end of the telescopic component 21 close to the expansion slot 71 to take or release the expansion card 72.

[0030] Specifically, the telescopic assembly 21 can be a cylinder, a hydraulic cylinder, a lead screw and a slider assembly, a gear 3131 and a rack 3132 assembly, etc., which can be limited according to actual needs. Figure 1 In the vertical direction of the expansion slot 71, the telescopic assembly 21 rises and falls in the first direction to move downward to insert the expansion card 72 into the expansion slot 71, or to move upward to remove the expansion card 72 from the expansion slot 71. The gripping assembly 22 can be a mechanical gripper, an electric gripper, a pneumatic gripper, etc., which is specifically limited according to actual needs.

[0031] In such an embodiment, the telescopic component 21 can automatically insert the expansion card 72 into the expansion slot 71 and release the expansion card 72 or clamp the expansion card 72 and remove the expansion card 72 from the expansion slot 71, saving manpower and thus improving the efficiency of the expansion card 72 plug-in and pull-out testing.

[0032] In some exemplary embodiments, referring to Figure 1As shown, the plug and unplug test device further includes an electrostatic eliminator 8, which is located at one end of the expansion slot 71 of the expansion card 72 close to the picking and placing mechanism 2 to eliminate the static electricity of the expansion card 72.

[0033] It should be noted that electrostatic discharge can cause the circuit components on the expansion card 72 to burn out or fail, and even slight discharge can cause irreversible damage. Static electricity may also cause intermittent failures, such as unstable data transmission or abnormal system operation. Therefore, electrostatic interference will affect data transmission, and further affect the plug and unplug test of the expansion card 72, resulting in a decrease in the accuracy of the plug and unplug test.

[0034] Specifically, the electrostatic eliminator 8 can be an electrostatic elimination ion air bar, an ion blower, a point-type electrostatic eliminator, an electrostatic neutralizer, etc., which are specifically selected according to actual needs. When in use, the electrostatic eliminator 8 ionizes air molecules into positive and negative ions, and blows the ionized positive and negative ions onto the surface of the expansion card 72. The positive and negative ions combine with the static charges on the surface of the expansion card 72 to neutralize the charges, thereby eliminating static electricity.

[0035] Furthermore, the electrostatic eliminator 8 extends in the length direction of the expansion slot 71 ( Figure 1 the front-back direction in Figure 1 ). In this way, the effective area for the electrostatic eliminator 8 to remove static electricity from the expansion card 72 can be increased. Specifically, during the process of the expansion card 72 being driven downward by the picking and placing mechanism 2 and inserted into the expansion slot 71, the side of the expansion card 72 facing the electrostatic eliminator 8 moves from bottom to top and successively to the front of the electrostatic eliminator 8 ( Figure 1 the left side of the electrostatic eliminator 8 in ). In this way, the electrostatic eliminator 8 can remove the static electricity on the side of the expansion card 72 facing the electrostatic eliminator 8, effectively eliminating the static electricity on the expansion card 72.

[0036] It can be understood that two groups of electrostatic eliminators 8 can be provided, and the two groups of electrostatic eliminators 8 are respectively located on both sides of the expansion card 72 in the length direction ( Figure 1 the left and right sides of the expansion card 72 in ), so as to effectively eliminate the static electricity on the expansion, weaken the influence of static electricity on the plug and unplug test of the expansion card 72, and improve the accuracy of the plug and unplug test of the expansion card 72.

[0037] In some exemplary embodiments, referring to Figure 1 , Figure 2 and Figure 3As shown, the pressing mechanism 3 includes a pressing component 31 and a locking component 32. The pressing component 31 is configured to have a first state of pressing the expansion card 72 towards the expansion slot 71 and a second state of separating from the expansion card 72 and allowing the expansion card 72 to be pulled out from the expansion slot 71. The locking component 32 is configured to have a locking state of locking with the pressing component 31, so that the pressing component 31 maintains the second state, and an unlocking state of separating from the pressing component 31, so that the pressing component 31 is adjusted from the second state to the first state.

[0038] Specifically, the pressing component 31 can be rotatably arranged on the mounting mechanism 1 through a rotating component, and rotate towards the expansion slot 71 to press the expansion card 72 to be in the first state, or rotate away from the expansion slot 71 to separate from the expansion card 72 to be in the second state. The pressing component 31 can also be telescopically arranged on the mounting mechanism 1 through a telescopic component 21, and move towards the expansion slot 71 to press the expansion card 72 to be in the first state, or move away from the expansion slot 71 to separate from the expansion card 72 to be in the second state.

[0039] Further, when the pressing component 31 is in the second state, the locking component 32 locks with the pressing component 31 to be in the locking state, so that the pressing component 31 maintains the second state. When the locking component 32 separates from the pressing component 31 to be in the unlocking state, the pressing component 31 is adjusted from the second state to the first state to further press the expansion card 72 towards the expansion slot 71, so that the expansion card 72 is inserted and removed in place.

[0040] In such an embodiment, during the insertion and removal test of the expansion card 72, the locking component 32 locks with the pressing component 31, so that the pressing component 31 maintains the second state. After the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71 and releases the expansion card 72, the locking component 32 separates from the pressing component 31 to be in the unlocking state, so that the pressing component 31 presses the expansion card 72 towards the expansion slot 71 and is adjusted to the first state. In this way, the pressing component 31 exerts a thrust force on the expansion card 72 towards the expansion slot 71, so that the expansion card 72 is further inserted into the expansion slot 71 to ensure that the expansion card 72 is inserted in place, avoid the inaccuracy of the insertion and removal test caused by incomplete insertion, and improve the accuracy of the insertion and removal test of the expansion card 72. Through the mutual cooperation of the pressing component 31 and the locking component 32, the insertion and removal test is automatically completed, and the efficiency of the insertion and removal test of the expansion card 72 is improved.

[0041] In some exemplary embodiments, referring to Figure 1 、 Figure 2 and Figure 4 As shown, the pressing component 31 includes a rotating portion 311 and a pressing portion 312. The rotating portion 311 rotates around a second direction parallel to the expansion card 72 and perpendicular to the first direction ( Figure 1It rotates about the axis in the length direction of the middle expansion card 72. The pressing part 312 is connected to the rotating part 311 and rotates with the rotating part 311 to rotate to the first state or the second state. The driving assembly 313 is configured to drive the rotating part 311 to rotate so that the pressing part 312 is adjusted to the first state or the second state.

[0042] Specifically, the rotating part 311 is a cylindrical rod-shaped structure. The rotating part 311 is parallel to the expansion card 72 and perpendicular to the first direction. The driving assembly 313 can be a gear 3131 and rack 3132 assembly, a group of gears 3131, a driving motor, etc., which are specifically determined according to actual needs.

[0043] The pressing part 312 is connected to the rotating part 311 by connection means including but not limited to bolts, screws, snap components, etc., so as to rotate about the axis in the second direction with the rotating part 311.

[0044] Specifically, at least one pressing part 312 can be provided. For example, one, two, three, four, etc. pressing parts 312 can be provided, which are specifically determined according to the size of the pressing part 312 and the size of the expansion card 72. When multiple pressing parts 312 are provided, the pressing parts 312 are distributed at intervals in the length direction of the expansion card 72.

[0045] In some exemplary embodiments, with reference to Figure 1 、 Figure 2 and Figure 4 as shown, two groups of pressing mechanisms 3 are provided. The two groups of pressing mechanisms 3 are respectively located on both sides in the length direction of the expansion card 72 ( Figure 1 the left and right sides of the expansion card 72 in the middle), and the pressing parts 312 of the two groups of pressing mechanisms 3 are located at the ends in the length direction of the expansion card 72 and are arranged staggeredly. In this way, the external force on the expansion card 72 by the pressing part 312 is more balanced, so that the expansion card 72 can be inserted into the expansion slot 71 more smoothly and inserted in place.

[0046] In such an implementation manner, the driving assembly 313 drives the rotating part 311 to rotate about the axis in the second direction, and at the same time the pressing part 312 rotates with the rotating part 311. Specifically, in Figure 1In the pressing mechanism 3 on the right side, the driving component 313 in the pressing mechanism 3 drives the rotating part 311 to rotate counterclockwise around the axis in the second direction. At the same time, the pressing part 312 rotates counterclockwise around the axis in the second direction along with the rotating part 311, so that one end of the pressing part 312 away from the rotating part 311 rotates towards the direction close to the expansion slot 71 to the first state, so as to contact the top of the expansion card 72 and press the expansion card 72 towards the direction close to the expansion slot 71, so that the expansion card 72 is inserted and removed in place, improving the accuracy of the insertion and removal test. On the contrary, under the drive of the driving component 313, the rotating part 311 and the pressing part 312 rotate clockwise around the axis in the second direction, so that one end of the pressing part 312 away from the rotating part 311 rotates towards the direction away from the expansion card 72 to the second state, so as to allow the picking and placing mechanism 2 to clamp the expansion card 72, so that the expansion card 72 is pulled out from the expansion slot 71. In this way, the expansion card 72 is automatically inserted into the expansion slot 71 or pulled out from the expansion slot 71, saving manpower and improving the efficiency and accuracy of the insertion and removal test of the expansion card 72.

[0047] In some exemplary embodiments, referring to Figure 2 and Figure 3 As shown, the driving component 313 includes a gear 3131, a rack 3132 and a driving member 4. The gear 3131 is coaxially connected to the rotating part 311. The rack 3132 is slidably arranged on the mounting mechanism 1 in a third direction perpendicular to both the first direction and the second direction and meshes with the gear 3131. In the first state, the rack 3132 is located at a first position away from the expansion slot 71. In the second state, the rack 3132 is located at a second position close to the expansion slot 71. The driving member 4 is configured to drive the rack 3132 to reciprocate between the first position and the second position, so that the gear 3131 rotates.

[0048] Specifically, the gear 3131 is arranged at the middle position of the rotating part 311, so that the force on the rotating part 311 is balanced. The rack 3132 includes but is not limited to being slidably arranged on the base frame 11 of the mounting mechanism 1 through a slider, a chute fit, a guide rod or any other connecting component. In the first state, the rack 3132 is located at a first position away from the expansion slot 71 ( Figure 3 the position where the rack 3132 is located in the figure). During the process of adjusting from the first state to the second state, the rack 3132 moves leftward in the third direction, so that in the second state, the rack 3132 is located at a second position close to the expansion slot 71 (not shown in the figure). The driving member 4 includes but is not limited to a cylinder, a hydraulic cylinder, a spring and a reset device, etc., which are specifically determined according to actual needs.

[0049] In such an embodiment, during the process that the driving member 4 drives the rack 3132 to move from the second position to the first position, that is Figure 3 in the figure, the rack 3132 moves from left to right to Figure 3The position in. Since the gear 3131 meshes with the rack 3132, during the movement of the rack 3132, the gear 3131 rotates counterclockwise, driving the rotating part 311 and the pressing part 312 to rotate counterclockwise. As a result, the end of the pressing part 312 away from the rotating part 311 presses the top of the pre-expansion card 72, and presses the expansion card 72 into the expansion slot 71, making the expansion card 72 inserted and removed in place, and improving the accuracy of the insertion and removal test of the expansion card 72.

[0050] In some exemplary embodiments, referring to Figure 2 , Figure 3 and Figure 4 shown, the driving component 4 includes a guiding component 41, a first elastic component 42 and a reset component 43. The guiding component 41 is disposed on the rack 3132 and is slidably engaged with the mounting mechanism 1 in the third direction to guide the sliding of the rack 3132. The first elastic component 42 is elastically disposed between the rack 3132 and the mounting mechanism 1 in the third direction to drive the rack 3132 to slide from the second position to the first position. The reset component 43 expands and contracts in the third direction to drive the rack 3132 to slide from the first position to the second position.

[0051] Specifically, the guiding component 41 can be a guiding rod, a guiding groove 6, etc., which is specifically determined according to actual needs. The guiding component 41 guides the sliding of the rack 3132, reduces the degree of shaking during the sliding of the rack 3132, and improves the smoothness during the sliding of the rack 3132.

[0052] Furthermore, the first elastic component 42 can be a spring, an airbag, a shock absorber, etc. The first elastic component 42 can be elastically disposed between the rack 3132 and the mounting mechanism 1. The reset component 43 can be a cylinder, an electric push rod, etc., which is specifically determined according to actual needs.

[0053] In such an embodiment, during the process of the driving component 4 driving the rack 3132 to move, the reset component 43 drives the rack 3132 to slide from the first position to the second position, making the first elastic member in a stretched state. At the same time, the gear 3131 drives the rotating rod and the pressing part 312 to rotate clockwise, so that the pressing part 312 rotates to the second state. At this time, the locking assembly 32 locks with the pressing assembly 31, so that the pressing part 312 maintains the second state to allow the picking and placing mechanism 2 to pull out the expansion card 72 from the expansion slot 71.

[0054] After the pick-and-place mechanism 2 inserts the expansion card 72 into the expansion slot 71 and releases the expansion card 72, the locking component 32 is separated from the pressing component 31 and is in an unlocked state. The first elastic component 42 in a stretched state contracts, thereby driving the rack 3132 to move from the second position to the first position. At the same time, the gear 3131 drives the rotating rod and the pressing part 312 to rotate counterclockwise, so that the pressing part 312 rotates to the first state. At this time, the pressing part 312 presses the expansion card 72 in the direction close to the expansion slot 71, so that the expansion card 72 is inserted in place, thereby improving the accuracy of the plugging and unplugging test of the expansion card 72.

[0055] In some exemplary embodiments, referring to Figure 3 , Figure 4 and Figure 5 as shown, the mounting mechanism 1 is provided with a guiding groove 6 extending in the third direction ( Figure 4 the substantially lateral direction in

[0056] Specifically, the base frame 11 includes a mounting plate provided in the horizontal direction. The guiding groove 6 penetrates the mounting plate and extends in the third direction. The longitudinal section of the sliding part 411 is a T-shaped structure, and the sliding part 411 includes a first part and a second part. The first part is detachably connected to the rack 3132, and the first part is located in the guiding groove 6 and slides along the guiding groove 6. The second part is connected to one end of the first part away from the rack 3132. The cross section of the second part is larger than the caliber of the guiding groove 6, and the second part is in sliding contact with the side of the mounting plate facing away from the rack 3132 to prevent the sliding part 411 from detaching from the guiding groove 6.

[0057] In this way, during the movement of the rack 3132, the first part of the sliding part 411 slides in the guiding groove 6, thereby guiding the rack 3132 to slide in the third direction, reducing the degree of shaking during the movement of the rack 3132, and improving the smoothness of the sliding of the rack 3132.

[0058] In some exemplary embodiments, referring to Figure 3 , Figure 4 and Figure 5 as shown, a plurality of convex portions 61 are provided on the inner wall of the guiding groove 6 extending in the third direction. The convex portions 61 protrude from the inner wall of the guiding groove 6. The convex portions 61 increase the roughness and frictional resistance of the inner wall of the guiding groove 6, thereby increasing the frictional resistance between the sliding part 411 and the guiding groove 6 and reducing the sliding speed of the sliding part 411 in the guiding groove 6. In this way, when the pressing part 312 rotates and contacts in the direction close to the expansion card 72, due to the action of the frictional resistance generated by the convex portions 61 on the sliding part 411, the impact force of the pressing part 312 on the expansion card 72 is weakened, and the damage to the expansion card 72 is reduced.

[0059] In some illustrative embodiments, referring to Figure 4 as shown, a gasket 3121 is provided on one side of the end face of the pressing portion 312 away from the rotating portion 311 facing the expansion card 72. The gasket 3121 is made of a flexible material. For example, the gasket 3121 can be a rubber sheet, a silicone sheet, etc. When the pressing portion 312 presses the expansion card 72, the gasket 3121 contacts the expansion card 72 and undergoes a slight deformation to absorb part of the impact force of the pressing portion 312 on the expansion card 72, playing a role of shock absorption and buffering, and improving the protection of the expansion card 72.

[0060] In some illustrative embodiments, referring to Figure 2 and Figure 3 as shown, the guiding member 41 further includes a guiding portion 412 and a limiting portion 413. The guiding portion 412 is disposed on the rack 3132, partially passes through the mounting mechanism 1, and slides relative to the mounting mechanism 1 in the third direction to guide the sliding of the rack 3132. The limiting portion 413 is disposed at one end of the guiding portion 412 away from the rack 3132. When the rack 3132 slides to the second position, the limiting portion 413 abuts against the mounting mechanism 1 to prevent the rack 3132 from sliding relative to the mounting mechanism 1.

[0061] Specifically, the mounting mechanism 1 further includes a mounting seat which is disposed on the mounting plate and is vertically arranged. The guiding portion 412 extends in the third direction, passes through the mounting seat, and slides relative to the mounting seat in the third direction. The first elastic member 42 is sleeved on the guiding portion 412 and is disposed between the mounting seat and the rack 3132.

[0062] In such an embodiment, during the sliding process of the rack 3132, the guiding rod slides synchronously with the rack 3132. The guiding rod slides relative to the mounting seat in the third direction, thereby guiding the sliding of the rack 3132 and improving the smoothness of the sliding of the rack 3132. When the rack 3132 slides from the first position to the second position, the limiting portion 413 abuts against the mounting mechanism 1 to counteract the elastic force of the first elastic portion and prevent the rack 3132 from continuing to slide relative to the mounting mechanism 1, so that the rack 3132 is maintained in the second position to facilitate the locking of the rack 3132 by the locking assembly 32.

[0063] In some illustrative embodiments, referring to Figure 2 and Figure 3As shown, the locking assembly 32 includes a second elastic member 321, a locking portion 322, and an unlocking assembly 5. The second elastic member 321 is elastically disposed on the mounting mechanism 1. The locking portion 322 is disposed at one end of the second elastic member 321 close to the rack 3132 to be inserted into the locking hole of the rack 3132 to be in a locked state, so that the rack 3132 is in the second position, or to disengage from the locking hole to be in an unlocked state, so that the rack 3132 slides from the second position to the first position. The unlocking assembly 5 is configured to drive the locking portion 322 to disengage from the locking hole against the elastic force of the second elastic member 321 when the expansion card 72 is inserted into the expansion slot 71, and when the expansion card 72 is pulled out from the expansion slot 71, the second elastic member 321 drives the locking portion 322 to be inserted into the locking hole.

[0064] Specifically, the second elastic member 321 can be a spring. The second elastic member 321 expands and contracts in a direction close to or away from the rack 3132. Specifically, the second elastic member 321 extends in the vertical direction, and the second elastic member 321 can also extend in the horizontal direction, which is not limited herein. The locking portion 322 is disposed at one end of the second elastic member 321 close to the rack 3132 ( Figure 3 the bottom end of the second elastic member 321 in the figure). At the second position, a locking hole is provided at a position of the rack 3132 opposite to the locking portion 322.

[0065] It should be noted that the bottom end of the locking portion 322 is lower than the top surface of the rack 3132. When the expansion card 72 is pulled out from the expansion slot 71, during the process that the reset member 43 drives the rack 3132 to move from the first position to the second position, the bottom end of the locking portion 322 contacts and slides relative to the top surface of the rack 3132, and at the same time, under the extrusion force of the rack 3132, the second elastic member 321 is compressed. When the rack 3132 moves to the second position, the locking portion 322 is opposite to the locking hole, and the second elastic member 321 extends and drives the locking portion 322 to be inserted into the locking hole to be in a locked state, so that the rack 3132 maintains the second position, and at the same time, the pressing portion 312 is in a released state.

[0066] Furthermore, when the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71, the unlocking assembly 5 drives the locking portion 322 to disengage from the locking hole against the elastic force of the second elastic member 321, so that the first elastic member 42 in the extended state contracts and drives the rack 3132 to move from the second position to the first position, and further enables the gear 3131 to drive the rotating portion 311 and the pressing portion 312 to rotate towards the direction close to the expansion card 72, and further inserts the expansion card 72 into the expansion slot 71.

[0067] In such an embodiment, the locking portion 322 can be inserted into the locking hole of the rack 3132 in the second position to be in the locked state, so that the rack 3132 maintains the second position, while the pressing portion 312 is in the released state. At this time, the picking and placing mechanism 2 can insert the expansion card 72 into the expansion slot 71. After the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71, the unlocking assembly 5 moves synchronously, so that the locking portion 322 disengages from the locking hole, so that the rack 3132 moves from the second position to the first position under the action of the first elastic member 42, so that the pressing portion 312 further inserts the expansion card 72 into the expansion slot 71 and is in the first state. Through the coordinated action of the locking assembly 32 and the pressing assembly 31, the plug and unplug test of the expansion card 72 is automatically completed, improving the efficiency and accuracy of the plug and unplug test of the expansion card 72.

[0068] In some illustrative embodiments, referring to Figure 2 and Figure 3 as shown, the unlocking assembly 5 includes an unlocking member 51 and a cooperating portion 52. The unlocking member 51 is configured to drive the locking portion 322 to be adjusted to the unlocked state. The cooperating portion 52 is disposed at one end of the picking and placing mechanism 2 close to the expansion slot 71, so that when the expansion card 72 is inserted into the expansion slot 71, it contacts the unlocking member 51, so that the unlocking member 51 drives the locking portion 322 to be adjusted to the unlocked state. When the expansion card 72 is pulled out of the expansion slot 71, the cooperating portion 52 is separated from the unlocking member 51, allowing the second elastic member 321 to drive the locking portion 322 to be adjusted to the locked state.

[0069] Specifically, while the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71, the cooperating portion 52 moves with the picking and placing mechanism 2 and contacts the unlocking member 51, so that the unlocking member 51 drives the locking portion 322 to be adjusted to the unlocked state, and further causes the rack 3132 to move away from the expansion slot 71, so as to drive the pressing portion 312 to rotate towards the expansion card 72 to the first state and further insert the expansion card 72 into the expansion slot 71.

[0070] In this way, the unlocking assembly 5 can be linked with the picking and placing mechanism 2. When the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71, the unlocking assembly 5 timely drives the locking portion 322 to be adjusted to the unlocked state, so that the pressing portion 312 rotates to the first state.

[0071] Furthermore, when the expansion card 72 is pulled out of the expansion slot 71, the cooperating portion 52 is separated from the unlocking member 51. When the reset member 43 drives the rack 3132 to move from the first position to the second position, the second elastic member 321 is allowed to drive the locking portion 322 to be inserted into the locking hole and be in the locked state.

[0072] In some illustrative embodiments, referring to Figure 2 and Figure 3As shown, the unlocking component 51 includes a support portion 511 and a swinging portion 512. The middle part of the swinging portion 512 is rotatably arranged on the support portion 511, and the first end of the swinging portion 512 contacts the locking portion 322. Among them, when the engaging portion 52 contacts the second end of the swinging portion 512 and moves towards the direction close to the rack 3132, the first end of the swinging portion 512 moves away from the rack 3132 against the elastic force of the second elastic component 321 to move the locking portion 322 to the unlocking state. When the engaging portion 52 separates from the second end of the swinging portion 512, under the elastic force of the second elastic component 321, the first end of the swinging portion 512 and the locking portion 322 move towards the direction close to the rack 3132, so that the locking portion 322 is adjusted to the locking state.

[0073] Specifically, the swinging portion 512 includes, but is not limited to, being rotatably arranged on the support portion 511 through a pivot or a hinge assembly. The first end ( Figure 3 the left end of the swinging portion 512 in this case) of the swinging portion 512 contacts the locking portion 322. The second end ( Figure 3 the right end of the swinging portion 512 in this case) of the swinging portion 512 is in a suspended state.

[0074] In such an embodiment, when the picking and placing mechanism 2 inserts the expansion card 72 into the expansion slot 71, the engaging portion 52 moves downward with the picking and placing mechanism 2 and contacts the second end of the swinging portion 512. The second end of the swinging portion 512 swings downward under the downward acting force of the engaging portion 52, so that the first end of the swinging portion 512 moves upward. In this way, the swinging portion 512 moves the locking portion 322 away from the rack 3132 ( Figure 3 the upward direction in this case) against the elastic force of the second elastic component 321, so that the locking portion 322 disengages from the locking hole and is adjusted to the unlocking state.

[0075] When the picking and placing mechanism 2 pulls out the expansion card 72 from the expansion slot 71, the engaging portion 52 moves upward with the picking and placing mechanism 2 and separates from the second end of the swinging portion 512. At this time, the locking portion 322 moves downward under the elastic force of the second elastic component 321, allowing the locking portion 322 to be inserted into the locking hole and adjusted to the locking state.

[0076] In some exemplary embodiments, referring to Figure 2 and Figure 3 as shown, the locking portion 322 includes a contact portion 3221 and an insertion portion 3222. The contact portion 3221 is connected to the second elastic component 321. The insertion portion 3222 is arranged on the side of the contact portion 3221 close to the rack 3132. A through groove 5121 for accommodating the insertion portion 3222 is provided at the first end of the swinging portion 512, so that the swinging portion 512 contacts the side of the contact portion 3221 close to the rack 3132 and drives the locking portion 322 to be adjusted to the unlocking state.

[0077] In some illustrative embodiments, referring to Figure 3 as shown, one end of the insertion part 3222 close to the rack 3132 is hemispherical.

[0078] Specifically, referring to Figure 3 as shown, the top end of the contact part 3221 is connected to the second elastic member 321 by, but not limited to, bolts, welding or any other connection means. The insertion part 3222 is arranged on the side of the contact part 3221 close to the rack 3132 ( Figure 3 the bottom surface of the rack 3132 in ), and the bottom end of the insertion part 3222 is hemispherical.

[0079] In such an embodiment, during the process of the rack 3132 moving from the first position to the second position, the rack 3132 first contacts the bottom end of the insertion part 3222 and slides relative to it. The bottom end of the insertion part 3222 is arranged to be hemispherical to avoid the phenomenon that the rack 3132 is stuck due to interference between the insertion part 3222 and the edge position of the rack 3132. In addition, during the process of the rack 3132 moving towards the locking part 322, the hemispherical structure facilitates the relative sliding between the rack 3132 and the insertion part 3222, and counteracts the elastic force of the second elastic member 321 to cause the second elastic member 321 to contract, so that the rack 3132 moves to the second position under the drive of the reset member 43. Subsequently, when the locking hole is opposite to the insertion part 3222, the insertion part 3222 is inserted into the locking hole under the drive of the second elastic member 321. In this way, the hemispherical structure at the bottom end of the insertion part 3222 can reduce the probability of collision with the edge position of the locking hole and facilitate the insertion of the insertion part 3222 into the locking hole.

[0080] Further, a through groove 5121 for accommodating the insertion part 3222 is provided at the first end of the swinging part 512 ( Figure 3 the left end of the swinging part 512 in ), so that the first end of the swinging part 512 contacts the side of the contact part 3221 close to the rack 3132 and drives the locking part 322 to be adjusted to the unlocked state. Specifically, when the cooperating part 52 moves downward to press the second end of the swinging part 512, the first end of the swinging part 512 moves upward, thereby pushing the contact part 3221 upward against the elastic force of the second elastic member 321. The insertion part 3222 is located in the through groove 5121, so that the through groove 5121 limits the insertion part 3222 and guides the movement of the insertion part 3222, reducing the degree of shaking during the movement of the insertion part 3222.

[0081] According to the plug-and-play test device provided by the present application, when performing a plug-and-play test on an expansion card, the electronic component 7 is positioned on the installation mechanism 1. Since the picking and placing mechanism 2 expands and contracts in the first direction, the picking and placing mechanism 2 can insert the expansion card 72 into the expansion slot 71 and release it. Then, the pressing mechanism 3 presses the expansion card 72 in the direction close to the expansion slot 71, so that the expansion card 72 is inserted in place, improving the accuracy of the plug-and-play test. Subsequently, when the expansion card 72 is pulled out from the expansion slot 71, the pressing mechanism 3 is separated from the expansion card 72, so that the picking and placing mechanism 2 clamps the expansion card 72 and pulls out the expansion card 72 from the expansion slot 71, thereby automatically completing a single plug-and-play test of the expansion card 72. After multiple cycles, multiple plug-and-play tests of the expansion card 72 are automatically completed. Therefore, the technical problems of low efficiency and low accuracy of the plug-and-play test of the expansion card 72 can be solved, and the technical effects of improving the efficiency and accuracy of the plug-and-play test of the expansion card 72 can be achieved.

[0082] The above has introduced in detail a plug-and-play test device provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
