Description
Technical Field
[0001] The present application relates to the field of testing technology, and in particular to a plug-in test device. Background Art
[0002] An expansion card is an electronic component that is inserted into the expansion slot of an electronic device's motherboard, allowing the electronic device to expand specific functions and improve performance.
[0003] Expansion cards need to be inserted and removed from the expansion slot multiple times to perform a plug-in test to verify the physical connection between the expansion card's gold fingers and the expansion slot's contacts. However, this expansion card plug-in test relies on manual labor, which can lead to improper insertion of the expansion card, resulting in low accuracy and test efficiency. Summary of the Invention
[0004] The present application provides a plug-in test device to at least solve the problems of low efficiency and low accuracy of expansion card plug-in test in the related art, thereby achieving the effect of improving the efficiency and accuracy of expansion card plug-in test.
[0005] The present application provides a plug-in and pull-out testing device, comprising: a mounting mechanism, configured to position an electronic component, wherein the electronic component is provided with an expansion slot for accommodating an expansion card; a pick-and-place mechanism, extending and retracting in a first direction, configured to insert the expansion card into the expansion slot and release the expansion card or to clamp the expansion card and pull the expansion card out of the expansion slot; and a pressing mechanism, configured to press the expansion card toward the expansion slot when the expansion card is inserted into the expansion slot, and to separate from the expansion card and allow the expansion card to be pulled out of the expansion slot when the expansion card is pulled out of the expansion slot.
[0006] Through the present application, when performing a plug-in and pull-out test on an expansion card, the electronic component is positioned on the installation mechanism. Since the pick-up and placement mechanism is extended and retracted in the first direction, the pick-up and placement mechanism can insert the expansion card into the expansion slot and release it. Then, the pressing mechanism presses the expansion card in the direction close to the expansion slot, so that the expansion card is inserted into place, thereby improving the accuracy of the plug-in and pull-out test. Subsequently, when the expansion card is pulled out of the expansion slot, the pressing mechanism separates from the expansion card, allowing the pick-up and placement mechanism to clamp the expansion card and pull the expansion card out of the expansion slot, thereby automatically completing a single expansion card plug-in and pull-out test. Multiple cycles can be repeated to automatically complete multiple expansion card plug-in and pull-out tests, saving manpower. Therefore, the technical problems of low efficiency and low accuracy of the expansion card plug-in and pull-out test can be solved, and the technical effect of improving the efficiency and accuracy of the expansion card plug-in and pull-out test can be achieved.

[0017] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0018] Before expansion cards are released to the market, they must undergo plug-in and pull-out testing and performance testing. During this testing process, the expansion card is manually inserted into or removed from the expansion slot to verify the stability of the physical connection between the expansion card's gold fingers and the slot's contacts. However, manual plug-in and pull-out testing can result in improper insertion of the expansion card, resulting in low accuracy and efficiency.
[0019] This application provides a plug-in test device, and describes the plug-in test device in detail in combination with its structure and working principle. Electronic equipment includes but is not limited to any computer, server, network device, storage device, etc. that uses an expansion card.
[0020] Reference Figure 1 As shown, the plug-in test device includes a mounting mechanism 1, a pick-and-place mechanism 2, and a pressing mechanism 3. The mounting mechanism 1 is configured to position an electronic component 7, which is provided with an expansion slot 71 for accommodating an expansion card 72. The pick-and-place mechanism 2 is retractable in a first direction and configured to insert the expansion card 72 into the expansion slot 71 and release the expansion card 72, or to clamp the expansion card 72 and pull the expansion card 72 out of the expansion slot 71. The pressing mechanism 3 is configured to press the expansion card 72 toward the expansion slot 71 when the expansion card 72 is inserted into the expansion slot 71, and to separate from the expansion card 72 when the expansion card 72 is pulled out of the expansion slot 71, allowing the expansion card 72 to be pulled out of the expansion slot 71.
[0021] Specifically, electronic component 7 can be a motherboard. It includes an expansion slot 71 for accommodating an expansion card 72. Expansion slot 71 includes contacts for physically connecting to the gold fingers of expansion card 72. Expansion card 72 is typically inserted into expansion slot 71 on the motherboard for use. Expansion card 72 requires insertion and removal testing to verify the stability of the physical connection between the gold fingers of expansion card 72 and the contacts of expansion slot 71.
[0022] Specifically, the mounting mechanism 1 includes, but is not limited to, a base frame 11 and a positioning assembly, for placing the electronic component 7 on the base frame 11 and securing it to the base frame 11 via the positioning assembly to position the electronic component 7 and prevent it from moving relative to the base frame 11. The positioning assembly includes, but is not limited to, detachable connectors such as bolts and snap assemblies to facilitate disassembly and replacement of the positioning assembly.
[0023] It should be noted that the first direction ( Figure 1 The vertical direction in the figure can represent the extension direction of expansion slot 71. A pick-and-place mechanism 2 is disposed at the end of expansion slot 71. This mechanism includes, but is not limited to, a pneumatic cylinder and gripping assembly 22, a hydraulic cylinder and gripping assembly 22, a robotic arm, and the like, and is determined based on actual needs. The pick-and-place mechanism 2 is configured to grip or release expansion card 72, and to extend and retract in a first direction to move expansion card 72 in the first direction into or out of expansion slot 71.
[0024] Furthermore, when performing an insertion / extraction test on expansion card 72, pick-and-place mechanism 2 grips expansion card 72 and moves toward expansion slot 71 to insert and release expansion card 72. Next, pressing mechanism 3 presses expansion card 72 toward expansion slot 71, pushing expansion card 72 further into expansion slot 71 so that expansion card 72 is fully inserted. This prevents test anomalies caused by expansion card 72 not being fully inserted, thereby improving the accuracy of the insertion / extraction test. After expansion card 72 has been within expansion slot 71 for a preset time, pressing mechanism 3 moves away from expansion card 72 to separate from expansion card 72, allowing pick-and-place mechanism 2 to grip expansion card 72 and remove it from expansion slot 71, thereby automatically completing a single insertion / extraction test. This cycle repeats multiple times to automatically complete multiple insertion / extraction tests on expansion card 72. The preset time can be 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, etc., and is determined based on actual needs.
[0025] In such an embodiment, when performing a plug-in test on the expansion card 72, the pick-and-place mechanism 2 can automatically insert the expansion card 72 into the expansion slot 71 or remove the expansion card 72 from the expansion slot 71. At the same time, after the pick-and-place 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, so that the expansion card 72 is inserted into the expansion slot 71, avoiding the situation where the expansion card 72 is not inserted into the proper position and causes test abnormalities, thereby improving the accuracy of the plug-in test. Through the cooperation of the pick-and-place mechanism 2 and the pressing mechanism 3, multiple plug-in tests of the expansion card 72 are 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 plug-in test of the expansion card 72 can be solved, and the technical effect of improving the efficiency and accuracy of the plug-in 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 11, a mounting portion 12, and a positioning portion 13. The base 11 is configured to accommodate the electronic component 7. The mounting portion 12 is disposed on the base 11. The positioning portion 13 is rotatably disposed on the mounting portion 12 and is configured to press the electronic component 7 against the base 11 to prevent the electronic component 7 from moving relative to the base 11.
[0027] For details, refer 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-up and placement 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 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 understood that the number of mounting portions 12 and positioning portions 13 is the same and they are used in conjunction with each other. Four mounting portions 12 and positioning portions 13 are provided, and are respectively positioned at the corners of the electronic component 7. This ensures that the external forces acting on the electronic component 7 by the mounting mechanism 1 are more balanced, further improving the stability of the positioning of the electronic component 7. It is understood that one, two, three, four, five, or six mounting portions 12 and positioning portions 13 may be provided, depending on 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 assembly 21 and a gripping assembly 22. The telescopic assembly 21 is telescopic in a first direction to move the expansion card 72 toward or away from the expansion slot 71. The gripping assembly 22 is disposed at one end of the telescopic assembly 21 near the expansion slot 71 to pick up or release the expansion card 72.
[0030] Specifically, the telescopic assembly 21 can be a cylinder, a hydraulic cylinder, a screw and 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 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 pull the expansion card 72 out of the expansion slot 71, saving manpower and thus improving the efficiency of the expansion card 72 insertion and removal test.
[0032] In some exemplary embodiments, referring to Figure 1As shown, the plug-in test device further includes a static eliminator 8 , which is located at one end of the expansion slot 71 of the expansion card 72 close to the pick-and-place mechanism 2 to eliminate static electricity on the expansion card 72 .
[0033] It should be noted that electrostatic discharge can burn or fail circuit components on expansion card 72, and even a slight discharge can cause irreversible damage. Static electricity can also cause intermittent failures, such as unstable data transmission or abnormal system operation. Therefore, electrostatic interference can affect data transmission and, in turn, reduce the accuracy of plug-in and unplug tests of expansion card 72.
[0034] Specifically, static eliminator 8 can be an ionizing wind bar, an ionizing blower, a point-type static eliminator, a static neutralizer, or the like, depending on actual needs. During use, static eliminator 8 ionizes air molecules into positive and negative ions, and then blows these ionized positive and negative ions toward the surface of expansion card 72. The positive and negative ions combine with the static charge on the surface of expansion card 72, neutralizing the charge and thus eliminating static electricity.
[0035] Furthermore, the static eliminator 8 is provided in the longitudinal direction of the expansion slot 71 ( Figure 1 In this way, the effective area of the static eliminator 8 for removing static electricity from the expansion card 72 can be increased. Specifically, when the expansion card 72 is driven downward by the pick-and-place mechanism 2 and inserted into the expansion slot 71, the side of the expansion card 72 facing the static eliminator 8 moves from bottom to top in sequence to the front of the static eliminator 8 ( Figure 1 In this way, the static eliminator 8 can remove static electricity on the side of the expansion card 72 facing the static eliminator 8, effectively eliminating static electricity on the expansion card 72.
[0036] It is understandable that two groups of static eliminators 8 can be provided, and the two groups of static 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 are provided), thereby effectively eliminating static electricity on the expansion card 72, reducing the impact of static electricity on the plug-in and pull-out test of the expansion card 72, and improving the accuracy of the plug-in and pull-out 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 in which it presses the expansion card 72 toward the expansion slot 71, and a second state in which it is separated from the expansion card 72 and allows the expansion card 72 to be removed from the expansion slot 71. The locking component 32 is configured to have a locked state in which it is locked with the pressing component 31, so that the pressing component 31 maintains the second state, and an unlocked state in which it is separated 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 assembly 31 can be rotatably mounted on the mounting mechanism 1 via a rotating assembly, so as to be rotated toward the expansion slot 71 to press the expansion card 72 and enter the first state, or rotated away from the expansion slot 71 to separate from the expansion card 72 and enter the second state. The pressing assembly 31 can also be telescopically mounted on the mounting mechanism 1 via a telescopic assembly 21, so as to be moved toward the expansion slot 71 to press the expansion card 72 and enter the first state, or moved away from the expansion slot 71 to separate from the expansion card 72 and enter the second state.
[0039] Furthermore, when the pressing assembly 31 is in the second state, the locking assembly 32 is locked with the pressing assembly 31 and is in the locked state, so that the pressing assembly 31 maintains the second state. When the locking assembly 32 is separated from the pressing assembly 31 and is in the unlocked state, the pressing assembly 31 adjusts from the second state to the first state, further pressing the expansion card 72 toward the expansion slot 71, so that the expansion card 72 is inserted and removed in place.
[0040] In such an embodiment, during the plug-in and pull-out test of the expansion card 72, the locking assembly 32 and the pressing assembly 31 are locked, so that the pressing assembly 31 maintains the second state. 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 assembly 32 separates from the pressing assembly 31 and is in the unlocked state, so that the pressing assembly 31 presses the expansion card 72 toward the expansion slot 71 and adjusts to the first state. In this way, the pressing assembly 31 applies a thrust toward the expansion slot 71 to the expansion card 72, causing the expansion card 72 to be further inserted into the expansion slot 71, thereby ensuring that the expansion card 72 is fully inserted, avoiding the impact of improper insertion on the accuracy of the plug-in and pull-out test, and improving the accuracy of the plug-in and pull-out test of the expansion card 72. The pressing assembly 31 and the locking assembly 32 cooperate with each other to automatically complete the plug-in and pull-out test, thereby improving the efficiency of the plug-in and pull-out test of the expansion card 72.
[0041] In some exemplary embodiments, referring to Figure 1 、 Figure 2 and Figure 4 As shown, the pressing assembly 31 includes a rotating portion 311 and a pressing portion 312. The rotating portion 311 rotates in a second direction ( Figure 1The pressing portion 312 is connected to the rotating portion 311 and rotates with the rotating portion 311 to rotate to the first state or the second state. The driving assembly 313 is configured to drive the rotating portion 311 to rotate, so that the pressing portion 312 is adjusted to the first state or the second state.
[0042] Specifically, the rotating portion 311 is a cylindrical rod structure, parallel to the expansion card 72 and perpendicular to the first direction. The driving component 313 can be a gear 3131 and rack 3132 assembly, a gear 3131 group, a driving motor, etc., which is determined according to actual needs.
[0043] The pressing portion 312 is connected to the rotating portion 311 by connection means including but not limited to bolts, screws, snap-fit assemblies, etc., so as to rotate along with the rotating portion 311 around the axis of the second direction.
[0044] Specifically, at least one pressing portion 312 may be provided. For example, one, two, three, or four pressing portions 312 may be provided, depending on the size of the pressing portion 312 and the size of the expansion card 72. If multiple pressing portions 312 are provided, the pressing portions 312 are spaced apart along the length of the expansion card 72.
[0045] In some exemplary embodiments, referring to Figure 1 、 Figure 2 and Figure 4 As shown, two groups of pressing mechanisms 3 are provided, and the two groups of pressing mechanisms 3 are respectively located on both sides of the length direction of the expansion card 72 ( Figure 1 The pressing portions 312 of the two sets of pressing mechanisms 3 are located at the ends of the expansion card 72 in the longitudinal direction and are staggered. This ensures that the external force exerted by the pressing portions 312 on the expansion card 72 is more balanced, allowing the expansion card 72 to be inserted more smoothly into the expansion slot 71 and into position.
[0046] In such an embodiment, the driving assembly 313 drives the rotating portion 311 to rotate around the axis of the second direction, and the pressing portion 312 rotates along with the rotating portion 311. Figure 1The driving assembly 313 in the pressing mechanism 3 located on the right side drives the rotating portion 311 to rotate counterclockwise around the axis in the second direction. Simultaneously, the pressing portion 312 rotates counterclockwise along with the rotating portion 311 around the axis in the second direction, causing the end of the pressing portion 312 away from the rotating portion 311 to rotate toward the expansion slot 71 to a first state, thereby contacting the top of the expansion card 72 and pressing the expansion card 72 toward the expansion slot 71, allowing the expansion card 72 to be inserted and removed in place, thereby improving the accuracy of the insertion and removal test. Conversely, driven by the driving assembly 313, the rotating portion 311 and the pressing portion 312 rotate clockwise around the axis in the second direction, causing the end of the pressing portion 312 away from the rotating portion 311 to rotate toward the second state, allowing the pick-and-place mechanism 2 to clamp the expansion card 72 and remove the expansion card 72 from the expansion slot 71. In this way, the expansion card 72 is automatically inserted into the expansion slot 71 or the expansion card 72 is automatically removed from the expansion slot 71, which saves manpower and improves the efficiency and accuracy of the expansion card 72 insertion and removal test.
[0047] In some exemplary embodiments, referring to Figure 2 and Figure 3 As shown, the drive assembly 313 includes a gear 3131, a rack 3132, and a drive component 4. The gear 3131 is coaxially connected to the rotating portion 311. The rack 3132 is slidably disposed on the mounting mechanism 1 in a third direction perpendicular to both the first and second directions, and meshes with the gear 3131. In a first state, the rack 3132 is located in a first position away from the expansion slot 71. In a second state, the rack 3132 is located in a second position closer to the expansion slot 71. The drive component 4 is configured to drive the rack 3132 to slide back and forth between the first and second positions, thereby rotating the gear 3131.
[0048] Specifically, the gear 3131 is disposed in the middle of the rotating portion 311 so that the force on the rotating portion 311 is balanced. The rack 3132 includes, but is not limited to, a slider, a slide groove, a guide rod, or any other connecting component that can be slidably disposed on the base 11 of the mounting mechanism 1. In the first state, the rack 3132 is located at a first position away from the expansion slot 71 ( Figure 3 During the adjustment 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 (not shown) adjacent to the expansion slot 71. The driving component 4 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a spring, and a reset device, and is determined based on actual needs.
[0049] In such an embodiment, the driving component 4 drives the rack 3132 to move from the second position to the first position, that is, Figure 3 The middle rack 3132 moves from left to right to Figure 3Because the gear 3131 is engaged with the rack 3132, the gear 3131 rotates counterclockwise during the movement of the rack 3132, driving the rotating portion 311 and the pressing portion 312 to rotate counterclockwise. As a result, the end of the pressing portion 312 away from the rotating portion 311 presses the top of the pre-expansion card 72 and presses the expansion card 72 into the expansion slot 71, so that the expansion card 72 is inserted and removed in place, thereby 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 As shown, the driving component 4 includes a guide component 41, a first elastic component 42, and a reset component 43. The guide component 41 is disposed on the rack 3132 and slidably engages with the mounting mechanism 1 in the third direction to guide 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 is retractable in the third direction to drive the rack 3132 to slide from the first position to the second position.
[0051] Specifically, the guide member 41 can be a guide rod, a guide slot 6, etc., which is determined according to actual needs. The guide member 41 guides the rack 3132 to slide, reduces the degree of shaking during the sliding process of the rack 3132, and improves the stability of the rack 3132 during the sliding process.
[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 arranged between the rack 3132 and the mounting mechanism 1. The reset component 43 can be a cylinder, an electric push rod, etc., which can be determined according to actual needs.
[0053] In this embodiment, as the drive component 4 drives the rack 3132 to move, the reset component 43 drives the rack 3132 to slide from the first position to the second position, causing the first elastic member to be in a stretched state. Simultaneously, the gear 3131 drives the rotating rod and the pressing portion 312 to rotate clockwise, causing the pressing portion 312 to rotate to the second position. At this point, the locking assembly 32 and the pressing assembly 31 are locked, maintaining the pressing portion 312 in the second position, allowing the access mechanism 2 to remove the expansion card 72 from the expansion slot 71.
[0054] After the access mechanism 2 inserts the expansion card 72 into the expansion slot 71 and releases the card, the locking assembly 32 separates from the pressing assembly 31 and enters the unlocked state. The first elastic member 42, which was in a stretched state, contracts, thereby driving the rack 3132 from the second position to the first position. Simultaneously, the gear 3131 drives the rotating rod and the pressing portion 312 to rotate counterclockwise, causing the pressing portion 312 to rotate to the first position. At this point, the pressing portion 312 presses the expansion card 72 toward the expansion slot 71, forcing it into place and improving the accuracy of the expansion card 72 insertion and removal test.
[0055] In some exemplary embodiments, referring to Figure 3 、 Figure 4 and Figure 5 As shown, the mounting mechanism 1 is provided with a Figure 4 The guide groove 6 extends in a substantially transverse direction thereof, and the guide component 41 includes a sliding portion 411, which slides in the guide groove 6 to guide the rack 3132 to slide.
[0056] In detail, the base frame 11 includes a mounting plate arranged in the horizontal direction. The guide groove 6 passes through the mounting plate and extends in the third direction. The longitudinal cross-section of the sliding portion 411 is a T-shaped structure, and the sliding portion 411 includes a first portion and a second portion. The first portion is detachably connected to the rack 3132, and the first portion is located in the guide groove 6 and slides along the guide groove 6. The second portion is connected to the end of the first portion away from the rack 3132. The cross-section of the second portion is larger than the diameter of the guide groove 6, and the second portion is in sliding contact with the side of the mounting plate away from the rack 3132 to prevent the sliding portion 411 from disengaging from the guide groove 6.
[0057] In this way, during the movement of the rack 3132, the first part of the sliding portion 411 slides in the guide 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, the inner wall of the guide groove 6 extending in the third direction is provided with a plurality of protrusions 61. The protrusions 61 are formed by outward projections from the inner wall of the guide groove 6. These protrusions 61 increase the roughness and frictional resistance of the inner wall of the guide groove 6, thereby increasing the frictional resistance between the sliding portion 411 and the guide groove 6 and reducing the sliding speed of the sliding portion 411 within the guide groove 6. Thus, when the pressing portion 312 rotates toward and contacts the expansion card 72, the protrusions 61 generate frictional resistance on the sliding portion 411, thereby reducing the impact force of the pressing portion 312 on the expansion card 72 and minimizing damage to the expansion card 72.
[0059] In some exemplary embodiments, referring to Figure 4 As shown, a gasket 3121 is provided on the side of the pressing portion 312 facing the expansion card 72, away from the rotating portion 311. The gasket 3121 is made of a flexible material. For example, the gasket 3121 can be a rubber sheet, a silicone sheet, or the like. When the pressing portion 312 presses the expansion card 72, the gasket 3121 contacts the expansion card 72 and slightly deforms to absorb some of the impact of the pressing portion 312 on the expansion card 72, providing a shock-absorbing and cushioning effect, and improving the protection of the expansion card 72.
[0060] In some exemplary embodiments, referring to Figure 2 and Figure 3 As shown, the guide member 41 further includes a guide portion 412 and a stopper 413. The guide 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 stopper 413 is disposed at an end of the guide portion 412 away from the rack 3132. When the rack 3132 slides to the second position, the stopper 413 abuts 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 vertically on the mounting plate. A guide portion 412 extends in the third direction, passes through the mounting seat, and slides relative to the mounting seat in the third direction. A first elastic member 42 is sleeved on the guide portion 412 and disposed between the mounting seat and the rack 3132.
[0062] In this embodiment, during the sliding process of the rack 3132, the guide rod slides synchronously with the rack 3132. The guide rod slides in the third direction relative to the mounting base, thereby guiding the sliding of the rack 3132 and improving the sliding smoothness of the rack 3132. When the rack 3132 slides from the first position to the second position, the stopper 413 abuts against the mounting mechanism 1 to counteract the elastic force of the first elastic portion, preventing the rack 3132 from sliding further relative to the mounting mechanism 1, thereby maintaining the rack 3132 in the second position, thereby facilitating the locking assembly 32 to lock the rack 3132.
[0063] In some exemplary embodiments, referring to Figure 2 and Figure 3As shown, the locking assembly 32 includes a second elastic component 321, a locking portion 322, and an unlocking assembly 5. The second elastic component 321 is elastically disposed on the mounting mechanism 1. The locking portion 322 is disposed at one end of the second elastic component 321 near the rack 3132, and can be inserted into the locking hole of the rack 3132 to lock the rack 3132, placing the rack 3132 in the second position, or released from the locking hole to unlock the rack 3132, causing the rack 3132 to slide from the second position to the first position. The unlocking assembly 5 is configured such that when the expansion card 72 is inserted into the expansion slot 71, the unlocking assembly 5 drives the locking portion 322 out of the locking hole against the elastic force of the second elastic component 321. When the expansion card 72 is removed from the expansion slot 71, the second elastic component 321 drives the locking portion 322 into the locking hole.
[0064] Specifically, the second elastic member 321 may 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 a vertical direction. The second elastic member 321 may also extend in a horizontal direction, which is not limited here. The locking portion 322 is provided at one end of the second elastic member 321 close to the rack 3132 ( Figure 3 In 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 height of the top surface of the rack 3132. When the expansion card 72 is removed from the expansion slot 71, the reset component 43 drives the rack 3132 from the first position to the second position. At the same time, the bottom end of the locking portion 322 contacts and slides relative to the top surface of the rack 3132. Simultaneously, the squeezing force of the rack 3132 compresses the second elastic component 321. When the rack 3132 moves to the second position, the locking portion 322 faces the locking hole. The second elastic component 321 stretches and drives the locking portion 322 into the locking hole, locking the rack 3132. This maintains the rack 3132 in the second position, while the pressing portion 312 is released.
[0066] Furthermore, when the pick-and-place mechanism 2 inserts the expansion card 72 into the expansion slot 71, the unlocking component 5 drives the locking portion 322 out of the locking hole against the elastic force of the second elastic component 321, so that the first elastic component 42 in the extended state contracts and drives the rack 3132 to move from the second position to the first position, thereby causing the gear 3131 to drive the rotating portion 311 and the pressing portion 312 to rotate toward the direction close to the expansion card 72, and further insert 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 and enter a locked state, so that the rack 3132 maintains the second position, and the pressing portion 312 is in a released state. At this time, the pick-and-place mechanism 2 can insert the expansion card 72 into the expansion slot 71. After the pick-and-place mechanism 2 inserts the expansion card 72 into the expansion slot 71, the unlocking assembly 5 moves synchronously, causing the locking portion 322 to disengage from the locking hole, thereby causing the rack 3132 to move from the second position to the first position under the action of the first elastic component 42, allowing the pressing portion 312 to further insert the expansion card 72 into the expansion slot 71 and enter the first state. Through the coordinated action of the locking assembly 32 and the pressing assembly 31, the expansion card 72 insertion and removal test is automatically completed, thereby improving the efficiency and accuracy of the expansion card 72 insertion and removal test.
[0068] In some exemplary embodiments, referring to Figure 2 and Figure 3 As shown, the unlocking assembly 5 includes an unlocking component 51 and a mating portion 52. The unlocking component 51 is configured to drive the locking portion 322 to an unlocked state. The mating portion 52 is disposed at one end of the access mechanism 2 near the expansion slot 71. When the expansion card 72 is inserted into the expansion slot 71, the mating portion 52 contacts the unlocking component 51, causing the unlocking component 51 to drive the locking portion 322 to an unlocked state. When the expansion card 72 is removed from the expansion slot 71, the mating portion 52 separates from the unlocking component 51, allowing the second elastic component 321 to drive the locking portion 322 to a locked state.
[0069] In detail, when the pick-and-place mechanism 2 inserts the expansion card 72 into the expansion slot 71, the mating portion 52 moves with the pick-and-place mechanism 2 and contacts the unlocking component 51, so that the unlocking component 51 drives the locking portion 322 to adjust to the unlocked state, thereby causing the rack 3132 to move away from the expansion slot 71, thereby driving the pressing portion 312 to rotate toward 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 component 5 can be linked with the pick-and-place mechanism 2. When the pick-and-place mechanism 2 inserts the expansion card 72 into the expansion slot 71, the unlocking component 5 promptly drives the locking portion 322 to adjust 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 engaging portion 52 separates from the unlocking portion 51. When the reset portion 43 drives the rack 3132 to move from the first position to the second position, the second elastic portion 321 is allowed to drive the locking portion 322 to be inserted into the locking hole and locked.
[0072] In some exemplary embodiments, referring to Figure 2 and Figure 3As shown, the unlocking component 51 includes a supporting portion 511 and a swinging portion 512. The middle portion of the swinging portion 512 is rotatably mounted on the supporting portion 511, and the first end of the swinging portion 512 contacts the locking portion 322. When the engaging portion 52 contacts the second end of the swinging portion 512 and moves toward the rack 3132, the first end of the swinging portion 512 resists the elastic force of the second elastic member 321, moving the locking portion 322 away from the rack 3132 and adjusting it to the unlocked state. When the engaging portion 52 separates from the second end of the swinging portion 512, the elastic force of the second elastic member 321 causes the first end of the swinging portion 512 and the locking portion 322 to move toward the rack 3132, causing the locking portion 322 to adjust to the locked state.
[0073] Specifically, the swing portion 512 includes but is not limited to being rotatably disposed on the support portion 511 via a pivot or hinge assembly. Figure 3 The left end of the middle swing portion 512) contacts the locking portion 322. The second end of the swing portion 512 ( Figure 3 The right end of the middle swing portion 512 is in a suspended state.
[0074] In this embodiment, when the pick-and-place mechanism 2 inserts the expansion card 72 into the expansion slot 71, the engaging portion 52 moves downward with the pick-and-place mechanism 2 and contacts the second end of the swing portion 512. The second end of the swing portion 512 swings downward under the downward force of the engaging portion 52, causing the first end of the swing portion 512 to move upward. In this way, the swing portion 512 resists the elastic force of the second elastic member 321 and moves in a direction away from the rack 3132 ( Figure 3 The locking portion 322 is moved in an upward direction (in the middle) so that the locking portion 322 is disengaged from the locking hole and adjusted to an unlocked state.
[0075] When the access mechanism 2 removes the expansion card 72 from the expansion slot 71, the engaging portion 52 moves upward along with the access mechanism 2 and separates from the second end of the swinging portion 512. At this point, the locking portion 322 moves downward under the elastic force of the second elastic member 321, allowing the locking portion 322 to be inserted into the locking hole and adjusted to a locked 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 member 321. The insertion portion 3222 is disposed on a side of the contact portion 3221 near the rack 3132. The first end of the swinging portion 512 is provided with a through slot 5121 for accommodating the insertion portion 3222, so that the swinging portion 512 contacts the side of the contact portion 3221 near the rack 3132 and drives the locking portion 322 to adjust to the unlocked state.
[0077] In some exemplary embodiments, referring to Figure 3 As shown, one end of the inserting portion 3222 close to the rack 3132 is hemispherical.
[0078] For details, refer to Figure 3 As shown, the top of the contact portion 3221 is connected to the second elastic component 321 by bolts, welding or any other connection method. The insertion portion 3222 is provided on one side of the contact portion 3221 close to the rack 3132 ( Figure 3 The bottom surface of the middle rack 3132), the bottom end of the insertion portion 3222 is hemispherical.
[0079] In this embodiment, as the rack 3132 moves from the first position to the second position, the rack 3132 first contacts and slides relative to the bottom end of the insertion portion 3222. The bottom end of the insertion portion 3222 is configured as a hemispherical shape to prevent interference between the insertion portion 3222 and the edge of the rack 3132, which could cause the rack 3132 to become stuck. Furthermore, as the rack 3132 moves toward the locking portion 322, the hemispherical structure facilitates relative sliding between the rack 3132 and the insertion portion 3222, counteracting the elastic force of the second elastic member 321, causing the second elastic member 321 to contract, allowing the rack 3132 to move to the second position under the drive of the reset member 43. Subsequently, when the locking hole and the insertion portion 3222 are opposite each other, the insertion portion 3222 is inserted into the locking hole under the drive of the second elastic member 321. Thus, the hemispherical structure of the bottom end of the insertion portion 3222 reduces the probability of collision with the edge of the locking hole, facilitating insertion of the insertion portion 3222 into the locking hole.
[0080] Furthermore, the first end of the swing portion 512 ( Figure 3 A through-slot 5121 is provided at the left end of the middle swing portion 512 to accommodate the insertion portion 3222. This allows the first end of the swing portion 512 to contact the side of the contact portion 3221 closest to the rack 3132, thereby driving the locking portion 322 to the unlocked position. Specifically, when the mating portion 52 moves downward to press the second end of the swing portion 512, the first end of the swing portion 512 moves upward, thereby pushing the contact portion 3221 upward against the elastic force of the second elastic member 321. The insertion portion 3222 is positioned within the through-slot 5121, which limits and guides the insertion portion 3222, reducing any shaking during movement.
[0081] According to the plug-in test device provided by the present application, when performing a plug-in test on an expansion card, the electronic component 7 is positioned on the mounting mechanism 1. Since the pick-up and placement mechanism 2 is extended and retracted in the first direction, the pick-up and placement 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 into place, thereby improving the accuracy of the plug-in test. Subsequently, when the expansion card 72 is pulled out of the expansion slot 71, the pressing mechanism 3 separates from the expansion card 72, so that the pick-up and placement mechanism 2 clamps the expansion card 72 and pulls the expansion card 72 out of the expansion slot 71, thereby automatically completing a single plug-in test of the expansion card 72. Multiple cycles can be repeated to automatically complete multiple plug-in tests of the expansion card 72. Therefore, the technical problems of low efficiency and low accuracy of the plug-in test of the expansion card 72 and low accuracy of the test results can be solved, thereby achieving the technical effect of improving the efficiency and accuracy of the plug-in test of the expansion card 72.

This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
