[0002] Before leaving the factory, chips need to be subjected to aging tests. The chips need to be placed in different environments and made to run specific functions, and then the performance of the chips is detected. Before the aging test, the BIB unit board loaded with the chips to be tested is first inserted into the resource board, and then the test chamber is closed to create a sealed environment for the aging test. After the aging test is completed, the test chamber needs to be opened first, and then the BIB unit board is separated from the resource board and taken out. At present, due to the complex process of the aging test and the long time-consuming manual operation, the efficiency of the aging test is low. Content of the Utility Model

[0039] Please refer to Figures 1 to 9 , the aging test device 10 in the preferred embodiment of the present utility model includes an automatic plugging device 100, a pre-pushing device 200, a cavity door device 300 and a box body 400.

[0040] An equipment cavity and a test cavity are formed inside the box body 400. The equipment cavity is used to accommodate devices for testing such as resource boards, and the test cavity can maintain the temperature required for testing and is used to accommodate the device under test. For the aging test, the device under test is the BIB unit board 20 equipped with several chips. The equipment cavity and the test cavity can be isolated by a heat insulation structure (not shown in the figure) to reduce the heat exchange efficiency between the equipment cavity and the test cavity. A signal board 410 is provided inside the box body 400, and both ends of the signal board 410 extend to the equipment cavity and the test cavity respectively. The signal board 410 can be a transfer board that plays a transfer role, so as to facilitate the connection between the resource board in the equipment cavity and the BIB unit board 20 in the test cavity. The power supply and control signals provided by the resource board can be transmitted to the BIB unit board 220 through the signal board 410 to complete the aging test procedure. In addition, in other embodiments, the signal board 410 can also be a resource board that can directly provide control signals.

[0041] The test cavity has an inlet and outlet (not marked in the figure), and the cavity door device 300 can open the inlet and outlet according to the door opening instruction, and can also close the inlet and outlet according to the door closing instruction. Please refer to Figure 2 together. The cavity door device 300 includes a door panel 310 and a cavity door driving mechanism 320. The cavity door driving mechanism 320 can drive the door panel 310 to move relative to the box body 400, so as to open or close the above-mentioned inlet and outlet.

[0042] Specifically, in this embodiment, the cavity door driving mechanism 320 includes a longitudinal driving component 321 and a transverse driving component 322. The longitudinal driving component 321 can drive the door panel 310 to move in a direction perpendicular to the plane of the inlet and outlet opening, so that the door panel 310 moves away from or covers the inlet and outlet. The transverse driving component 320 can drive the door panel 310 to move in a direction parallel to the plane of the inlet and outlet opening, so that the door panel 310 moves into or out of the range of the inlet and outlet.

[0043] Both the longitudinal driving component 321 and the transverse driving component 322 can be driven by air cylinders. When executing the door opening instruction, the longitudinal driving component 321 first drives the door panel 310 to move away from the inlet and outlet, and then the transverse driving component 320 drives the door panel 310 to move out of the range of the inlet and outlet. When executing the door closing instruction, the transverse driving component 320 first moves the door panel 310 into the range of the inlet and outlet, and then the longitudinal driving component 321 drives the door panel 310 to approach the inlet and outlet until the door panel 310 covers the inlet and outlet. It can be seen that the door panel 310 does not need to be flipped during the process of opening and closing the inlet and outlet, occupying less space and having a larger opening range.

[0044] Furthermore, the cavity door device 300 is also provided with a transverse sensor and a longitudinal sensor, the transverse sensor can detect the transverse (direction parallel to the plane of the inlet and outlet opening) position of the door panel 310, and the longitudinal sensor can detect the longitudinal (direction perpendicular to the plane of the inlet and outlet opening) position of the door panel 310. The transverse sensor and the longitudinal sensor cooperate to detect whether the door panel 310 is opened and closed in place.

[0045] The BIB unit board 20 is placed on the carrier 30. When the door panel 310 covers the inlet and outlet of the box 400, a sealed environment can be formed in the test cavity; when the door panel 310 opens the inlet and outlet of the box 400, the carrier 30 equipped with the BIB unit board 20 can be placed into the test cavity through the inlet and outlet. After the BIB unit board 20 is placed on the carrier 30 and the carrier 30 is placed in the test cavity, the pre-pushing device 200 can pre-push each BIB unit board 20 on the carrier 30, so that each BIB unit board 20 on the carrier 30 moves to a preset position toward the signal board 410 respectively. The automatic plug-in and unplug device 100 is arranged between the pre-pushing device 200 and the signal board 410, and is used to plug the BIB unit board 20 at the preset position on the carrier 30 with the signal board 410. That is to say, before the automatic plug-in device 100 plugs the BIB unit board 20 into the signal board 410, the pre-pushing device 200 is used to pre-push the BIB unit board 20 on the carrier frame 30, thereby ensuring that the BIB unit board 20 is in a preset position before plugging in, ensuring that the automatic plug-in device 100 can accurately plug the BIB unit board 20 into the signal board 410, and avoiding the phenomenon that the automatic plug-in device 100 fails to hook and pull the BIB unit board 20 or the BIB unit board 20 slips off.

[0046] Please also read Figures 3 to 5 The pre-pushing device 200 includes a pre-pushing assembly 210 and a pre-pushing driving assembly 220. The pre-pushing driving assembly 220 can drive the pre-pushing assembly 210 to switch to a pre-pushing state that pushes the BIB unit board 20 on the carrier 30 to a preset position (see Figure 3 ), and can drive the pre-thrust component 210 to switch to the avoidance state (see Figure 4 ) to allow the carrier 30 to enter and exit the test chamber.

[0047] The pre-pushing component 210 is generally movably connected to the box body 400. The pre-pushing drive component 220 is drivingly connected to the pre-pushing component 210 and is used to drive the pre-pushing component 210 to move relative to the box body 400, thereby driving the pre-pushing component 210 to switch between the pre-pushing state and the avoidance state. During actual use, first place the carrier 30 in the test cavity of the box body 400; then, the pre-pushing drive component 220 drives the pre-pushing component 210 to move relative to the box body 400 according to the pushing instruction until the pre-pushing component 210 switches to the pre-pushing state and pushes the BIB unit board 20 on the carrier 30 to a preset position, so as to ensure that the automatic plugging device 100 can accurately plug the BIB unit board 20 into the signal board 410, thereby avoiding phenomena such as the automatic plugging device 100 failing to hook the BIB unit board 20 or the BIB unit board 20 slipping off.

[0048] The above-mentioned preset position refers to the in-place position of the BIB unit board 20. When the BIB unit board 20 is at the preset position on the carrier 30, the automatic plugging device 100 can hook it to be plugged into the signal board 410. When placing the BIB unit board 20 on the carrier 30, there may be a situation where it is not in place, that is, the BIB unit board 20 does not reach the preset position. Using the pre-pushing component 210 to pre-push the BIB unit board 20 on the carrier 30 can position the BIB unit board 20 once, so as to ensure that each BIB unit board 20 on the carrier 30 is in the preset position.

[0049] The pre-pushing drive component 220 drives the pre-pushing component 210 to move to the avoidance state according to the pushing-out instruction. At this time, the pre-pushing component 210 allows the carrier 30 to enter and exit the test cavity of the box body 400 through the inlet and outlet. That is, the pre-pushing component 210 does not block the inlet and outlet.

[0050] In this embodiment, the pre-pushing component 210 includes a rotating shaft 211, a connecting piece 212, and a push rod 213. The rotating shaft 211 is rotatably connected to the box body 400. The push rod 213 is fixedly connected to the rotating shaft 211 through the connecting piece 212. The push rod 213 is used to push the BIB unit board 20 on the carrier 30. The pre-pushing drive component 220 is drivingly connected to the rotating shaft 211 to drive the rotating shaft 211 to rotate.

[0051] The pre-pushing drive assembly 220 can be driven by a cylinder. The pre-pushing drive assembly 220 is drivingly connected to the rotating shaft 211 to drive the rotating shaft 211 to rotate around its own axis, so that the rotating shaft 211 drives the push rod 213 to rotate around the rotating shaft 211 through the connecting member 212, and further enables the push rod 213 to push each BIB unit board 20 on the carrier 30 to a preset position. Further, under the driving action of the pre-pushing drive assembly 220, the rotating shaft 211 can also drive the push rod 213 to rotate outside the range of the inlet and outlet of the box body 400, and the pre-pushing assembly 210 switches to the avoidance state, so that the carrier 30 can smoothly enter the test cavity from the inlet and outlet.

[0052] The connecting member 212 is provided with a stop portion. When the pre-pushing assembly 210 is in the pre-pushing state, under the driving action of the pre-pushing drive assembly 220, the rotating shaft 211 drives the push rod 213 to rotate to the inlet and outlet of the box body 400, so that the push rod 213 pushes each BIB unit board 20 on the carrier 30 to move relative to the carrier 30 to a preset position. At this time, the stop portion on the connecting member 212 is in stop cooperation with the carrier 30, thereby preventing the carrier 30 from retreating from the inlet and outlet of the box body 400.

[0053] Specifically in the embodiment, one end of the connecting member 212 is fixedly connected to the rotating shaft 211, and the other end of the connecting member 212 is fixedly connected to the push rod 213, so that when the rotating shaft 211 rotates, it can drive the push rod 213 to rotate through the connecting member 212. When the pre-pushing assembly 210 is in the pre-pushing state, the end of the connecting member 212 connected to the push rod 213 is closer to the carrier 30 in the test cavity than the end of the connecting member 212 connected to the rotating shaft 211. When the pre-pushing assembly 210 is in the avoidance state, the end of the connecting member 212 connected to the push rod 213 is farther from the carrier 30 in the test cavity than the end of the connecting member 212 connected to the rotating shaft 211.

[0054] Optionally, the pre-pushing assembly 210 further includes a plurality of fixed seats 214 and a plurality of bearings. Each fixed seat 214 is fixedly connected to the box body 400. The rotating shaft 211 is respectively installed on each fixed seat 214 through each bearing, so that the rotating shaft 211 can rotate around its own axis relative to the box body 400 and each fixed seat 214. It should be noted that in some other embodiments, the rotating shaft 211 is installed on each fixed seat 214 through an oil-free bushing, or the rotating shaft 211 is installed on each fixed seat 214 in a manner of inserting and fitting the shaft and the hole, as long as the rotating shaft 211 can be rotated relative to each fixed seat 214, which is not limited herein.

[0055] It should be noted that the pre-pushing component 210 may include a push rod 213. Of course, in other embodiments, the pre-pushing component 210 may also include at least two push rods 213. The at least two push rods 213 are arranged along the axial direction of the rotating shaft 211 and are respectively fixedly connected to the rotating shaft 211 through their respective corresponding connecting members 212. In this way, the rotating shaft 211 can drive multiple push rods 213 to rotate simultaneously, so that each push rod 213 can pre-push the corresponding part of the BIB unit board 20 on the carrier 30, thereby ensuring that all the BIB unit boards 20 on the carrier 30 can be pre-pushed. It should be noted that the number of push rods 213 can be set according to the height of the carrier 30. The higher the height of the carrier 30, the more push rods 213 can be set; the lower the height of the carrier 30, the fewer push rods 213 can be set, as long as it is ensured that all the BIB unit boards 20 on the carrier 30 can be pre-pushed, and it is not limited here.

[0056] Optionally, the longitudinal ends of each push rod 213 are respectively fixedly connected to the rotating shaft 211 through the corresponding connecting members 212, so as to make the push rod 213 more stable and avoid the push rod 213 from shaking or deforming when pushing the BIB unit board 20. Of course, in other embodiments, the middle part of each push rod 213 can also be fixed to the rotating shaft 211 through the corresponding connecting member 212, as long as the push rod 213 is installed relatively stably, and it is not limited here.

[0057] Specifically in the embodiment, two pre-pushing devices 200 are provided, and the two pre-pushing devices 200 are respectively arranged on the opposite sides of the inlet and outlet of the box body 400. During actual use, the two pre-pushing drive components 220 respectively drive the rotating shafts 211 of the two pre-pushing components 210 to rotate, so as to drive the push rods 213 of the two pre-pushing components 210 to rotate away from each other and open until the push rods 213 of the two pre-pushing components 210 are outside the range of the inlet and outlet of the box body 400. At this time, both pre-pushing components 210 are in the avoidance state, so that the carrier 30 can enter and exit the test chamber from the inlet and outlet of the box body 400. Then, the carrier 30 is placed into the test chamber from the inlet and outlet; then the two pre-pushing drive components 220 respectively drive the rotating shafts 211 of the two pre-pushing components 210 to rotate, so as to drive the push rods 213 of the two pre-pushing components 210 to rotate towards each other and into the range of the inlet and outlet of the box body 400, and further make the push rods 213 of the two pre-pushing components 210 gradually approach each BIB unit board 20 on the carrier 30 until all the BIB unit boards 20 on the carrier 30 are jointly pushed to the preset position.

[0058] The push rods 213 of the two pre-pushing components 210 jointly push against each BIB unit board 20 on the carrier 30 from the opposite sides of the inlet and outlet, making the pushing of each BIB unit board 20 more stable and reliable, and avoiding deflection of each BIB unit board 20 during the movement.

[0059] In addition, please refer to again Figure 5 , in this embodiment, the pre-pushing drive component 220 includes a mounting base 222, a telescopic member 221 and an adapter block 223. The telescopic member 221 has a mounting end a1 and a telescopic end a2 opposite to the mounting end a1. The telescopic end a2 can be controllably telescoped relative to the mounting end a1. The adapter block 223 is fixedly connected to the rotating shaft 211. The mounting end a1 of the telescopic member 221 is hinged to the mounting base 222, and the telescopic end a2 of the telescopic member 221 is hinged to the adapter block 223. When the telescopic end a2 of the telescopic member 221 telescopes relative to the mounting end a1, it can drive the rotating shaft 211 to rotate around its own axis through the adapter block 223. Optionally, the telescopic member 221 can be a cylinder.

[0060] In this way, when the telescopic end a2 of the telescopic member 221 extends relative to the mounting end a1, the telescopic end a2 drives the rotating shaft 211 to rotate through the adapter block 223, and the rotating shaft 211 drives the push rod 213 to rotate away from the inlet and outlet 11 of the box body 400 until the push rod 213 is outside the range of the inlet and outlet 11 of the carrier 30, so that the carrier 30 can enter and exit the test chamber from this inlet and outlet.

[0061] When the telescopic end a2 of the telescopic member 221 retracts relative to the mounting end a1, the telescopic end a2 drives the rotating shaft 211 to rotate through the adapter block 223, and the rotating shaft 211 drives the push rod 213 to rotate towards the carrier 30 located in the test chamber until the push rod 213 pushes each BIB unit board 20 on the carrier 30 to a preset position.

[0062] Furthermore, the pre-pushing device 200 further includes a detection member arranged corresponding to the telescopic end a2 of the telescopic member 221, and this detection member is used to detect the position of the telescopic end a2 of the telescopic member 221. In this way, when the detection member detects that the telescopic end a2 of the telescopic member 221 extends relative to the mounting end a1, it indicates that the push rod 213 is outside the range of the inlet and outlet of the box body 400, and at this time the carrier 30 can enter and exit the test chamber of the box body 400 from this inlet and outlet. When the detection member detects that the telescopic end a2 of the telescopic member 221 retracts relative to the mounting end a1, it indicates that the push rod 213 is within the range of the inlet and outlet of the box body 400, and at this time the carrier 30 cannot enter and exit the test chamber of the box body 400 from this inlet and outlet. Optionally, the detection member can be a photoelectric sensor.

[0063] It should be noted that the pre-pushing drive assembly 220 is not limited to the above structure. Of course, other drive structures can also be adopted, as long as it can drive the rotating shaft 211 to rotate around its own axis, which is not limited herein. For example, the pre-pushing drive assembly 220 can also adopt a gear-rack drive structure. Specifically, the pre-pushing drive assembly 220 includes a gear, a rack, and a linear drive member. The gear is coaxially installed on the rotating shaft 211, so that the gear and the rotating shaft 211 can rotate synchronously. The rack is installed at the driving end of the linear drive member and meshes with the gear, so that when the linear drive member drives the rack to move, the rack can drive the gear to rotate, and then the rotating shaft 211 follows the gear to rotate around its own axis. Optionally, the linear drive member can adopt a cylinder.

[0064] The automatic plugging device 100 can pull the BIB unit board 20 located at a preset position towards the signal board 410 according to the docking instruction until the BIB unit board 20 is plugged into the signal board 410, and can push the BIB unit board 20 away from the signal board 410 according to the separation instruction until the BIB unit board 20 is separated from the signal board 410.

[0065] Please refer to Figure 6 and Figure 7 In this embodiment, the automatic plugging device 100 includes a first driving member 110, a support plate 120, a lifting frame 130, and a second driving member 140.

[0066] The support plate 120 is in transmission connection with the first driving member 110, and the first driving member 110 can drive the support plate 120 to reciprocate in the first direction. Specifically, the first driving member 110 can adopt a cylinder, and its telescopic shaft can be fixedly connected to the support plate 120 through a threaded fastener, and can directly drive the support plate 120. Obviously, in other embodiments, the first driving member 110 can also adopt an electric cylinder, a motor screw pair structure, etc. Moreover, the first driving member 110 and the support plate 120 can also be connected through a transmission member (not shown in the figure), and the first driving member 110 can indirectly drive the support plate 120 to move in the first direction.

[0067] Specifically in this embodiment, the automatic plugging device 100 further includes a fixing plate 150. The first driving member 110 is fixedly installed on one side of the fixing plate 150, the support plate 120 is located on the side of the fixing plate 150 facing away from the first driving member 110, and the driving end of the first driving member 110 passes through the fixing plate 150 and is connected to the support plate 120.

[0068] The fixing plate 150 plays a good supporting role on the first driving member 110, so that the first driving member 110 can maintain a high stability during the driving process, which helps to improve the operation accuracy of the automatic plugging and unplugging device 100. In addition, since the fixing plate 150 needs to avoid the signal board 410 and the BIB unit board 20, a hollow groove (not marked in the figure) is generally formed in the middle of the fixing plate 150.

[0069] Also, please see Figure 8 In this embodiment, the support plate 120 is in a long strip shape, each support plate 120 is transmission-connected to a plurality of first driving members 110 , and the plurality of first driving members 110 are spaced apart and distributed along the extension direction of the support plate 120 .

[0070] A large contact surface can be formed between the long strip support plate 120 and the lifting frame 130, so the lifting frame 130 can be kept stable when the support plate 120 drives the lifting frame 130 to move. Moreover, when the support plate 120 is driven to move along the first direction by multiple, such as two, first driving members 110, the force on the support plate 120 is more balanced, so the stability during the movement is higher. This helps to further improve the operating accuracy of the automatic plugging and unplugging device 100.

[0071] The lifting frame 130 is installed on the support plate 120. When the first driving member 110 drives the support plate 120 to move along the first direction, the support plate 120 can drive the lifting frame 130 to move along the first direction. Specifically in this embodiment, the automatic plugging and unplugging device 100 is provided with a plurality of support plates 120, and the plurality of support plates 120 are arranged at intervals, and the lifting frame 130 is respectively connected to the plurality of support plates 120. In this way, in the process of the support plate 120 driving the lifting frame 130 to move along the first direction, a plurality of, for example, three, support plates 120 can apply force to the lifting frame 130 from different positions, so that the lifting frame 130 is subjected to a more balanced force, thereby being able to improve the stability of the lifting frame 130 during the movement process.

[0072] Furthermore, the lifting frame 130 can move along the second direction relative to the support plate 120. The second direction is different from the first direction. Specifically, the second direction in this embodiment is perpendicular to the first direction. Figure 6 Up and down directions shown.

[0073] Please also read Figure 9 In this embodiment, the lifting frame 130 includes two oppositely arranged cross beams 132 and two guide groove plates 133 connecting the two cross beams 132 , and both ends of the support plate 120 are respectively connected to the two guide groove plates 133 .

[0074] The lifting frame 130 is generally in the shape of a rectangular frame structure, having high stability. Moreover, since both ends of the support plate 120 are respectively connected to the two guide groove plates 133, two connection points are formed between each support plate 120 and the lifting frame 130. When the support plate 120 drives the lifting frame 130 to move in the first direction, the acting force exerted by the support plate 120 on the lifting frame 130 is relatively balanced, so the stability of the lifting frame 130 during movement is further improved.

[0075] Furthermore, in this embodiment, each guide groove plate 133 is provided with a guide groove 1331 extending in the second direction, and the support plate 120 is inserted into the guide groove 1331 and can slide along the guide groove 1331. Moreover, in the first direction, the support plate 120 and the guide groove 1331 are in clearance fit.

[0076] The support plate 120 can slide along the guide groove 1331, so the lifting frame 130 and the support plate 120 have degrees of freedom in the second direction, thereby allowing the lifting frame 130 to move relative to the support plate 120 in the second direction. Moreover, the sliding connection between the lifting frame 130 and the support plate 120 can be realized through the guide groove 1331 without setting other components, so the structure of the automatic plugging and unplugging device 100 can also be simplified.

[0077] It should be noted that, in other embodiments, the connection between the lifting frame 130 and the support plate 120 can also be realized by the cooperation of a guide rail and a slider, and the guide rail extends in the second direction.

[0078] Even further, in this embodiment, two guiding blocks 121 are fixedly arranged on the support plate 120, and the two guiding blocks 121 respectively abut against one side of the two guide groove plates 133 facing the middle of the lifting frame 130. The two guiding blocks 121 abutting against the guide groove plates 133 can limit the relative position between the support plate 120 and the lifting frame 130 in the axial direction of the support plate 120, preventing the support plate 120 from sliding axially and sliding out of the guide groove 1331.

[0079] The lifting frame 130 is provided with a claw 131 that can be engaged with the BIB unit board 20. The specific form of the claw 131 can be designed according to the specific structure of the BIB unit board 20. Specifically, the claw 131 in this embodiment is generally in an L shape and can be inserted into the hook groove of the BIB unit board 20.

[0080] The second driving member 140 can also adopt structures such as air cylinders, electric cylinders or motor screw pairs. The second driving member 140 is arranged between the support plate 120 and the lifting frame 130, and can drive the lifting frame 130 to move relative to the support plate 120 along the second direction, so as to drive the claw 131 to be clamped or disengaged from the BIB unit board 20. For the case where a plurality of support plates 120 are provided, the second driving member 140 can be arranged between the lifting frame 130 and any one of the support plates 120. A plurality of second driving members 140 can also be provided and arranged at intervals along the extending direction of the support plate 120.

[0081] Take Figure 6 As shown in the figure, when the second driving member 140 drives the lifting frame 130 to move upward relative to the support plate 120, the claw 131 can be driven to engage with the engaging groove of the BIB unit board 20; when the second driving member 140 drives the lifting frame 130 to move downward relative to the support plate 120, the claw 131 can be driven to disengage from the engaging groove of the BIB unit board 20.

[0082] When it is necessary to insert the BIB unit board 20 at the preset position into the signal board 410 in an inserting manner, the first driving member 110 first drives the support plate 120 and the lifting frame 130 to move along the first direction towards the BIB unit board 20, so that the claw 131 moves to the lower side of the engaging groove of the BIB unit board 20; then the second driving member 140 drives the lifting frame 130 to move upward along the second direction until the claw 131 is engaged with the engaging groove of the BIB unit board 20. Then, the first driving member 110 drives the support plate 120 and the lifting frame 130 to move along the first direction towards the signal board 410 until the BIB unit board 20 is inserted into the signal board 410.

[0083] When it is necessary to disconnect the BIB unit board 20 from the signal board 410, the first driving member 110 drives the support plate 120 and the lifting frame 130 to move reversely along the first direction, and can push the BIB unit board 20 out of the signal board 410. In this embodiment, the operation process of the automatic plugging and unplugging device 100 is that the first driving member 110 drives the lifting frame 130 to move away from the signal board 410 along the first direction, and then makes the side of the lifting frame 130 abut against the BIB unit 20 and drives the BIB unit 20 to be separated from the signal board 410. That is to say, the claw 131 does not need to participate when separating the BIB unit board 20 from the signal board 410.

[0084] It can be seen that the above automatic plugging and unplugging device 100 can automatically perform the plugging and unplugging of the BIB unit board 20, and can improve the operation efficiency and accuracy.

[0085] In some other embodiments, before the first driving member 110 drives the lifting frame 130 to push the BIB unit board 20 away from the transfer board 200, the second driving member 140 can first drive the lifting frame 130 to move in the second direction, so that the hook 131 extends into the hook groove of the BIB unit 300, so as to reduce the risk of the BIB unit 300 popping out during the separation process of the BIB unit 300 and the transfer board 200. After the separation is completed, the second driving member 140 drives the lifting frame 130 to move in the reverse direction of the second direction, so that the hook 131 is disengaged from the hook groove of the BIB unit board 20.

[0086] Specifically, in this embodiment, multiple groups of hooks 131 are arranged on the lifting frame 130. The multiple groups of hooks 131 are arranged at intervals in the second direction and can be respectively engaged with multiple BIB unit boards 20. The multiple groups of hooks 131 can be respectively engaged with multiple groups of BIB unit boards 20, such as the hook grooves of the BIB unit board 20. Therefore, the automatic plugging and unplugging device 100 can simultaneously realize the plugging and unplugging of multiple BIB unit boards 20, so the operation efficiency is further improved.

[0087] It should be noted that each group generally includes multiple, such as two hooks 131. Multiple hooks 131 are simultaneously engaged with a BIB unit board 20, which can improve the stability of the BIB unit board 20 during the plugging and unplugging process, thereby improving the operation accuracy.

[0088] Furthermore, in this embodiment, the multiple groups of hooks 131 are distributed in at least two installation areas of the lifting frame 130 arranged in the second direction, and a support plate 120 is arranged between adjacent two installation areas. During the process of the hook 131 pushing and pulling the BIB unit board 20, the installation area of the lifting frame 130 in the installation area will receive the reaction force of the BIB unit board 20. The support plate 120 arranged between adjacent two installation areas can apply a force in the direction opposite to the above reaction force to the lifting frame 130. In this way, the force on the lifting frame 130 can be made more uniform, and the lifting frame 130 can be prevented from deforming.

[0089] Please refer to again Figure 7 and Figure 8 , in this embodiment, the automatic plugging and unplugging device 100 further includes a first limiting member 161 and a second limiting member 162, and the support plate 120 can move within the range defined by the first limiting member 161 and the second limiting member 162 along the first direction.

[0090] The first limiting member 161 and the second limiting member 162 cooperate to control the stroke of the first driving member 110, so as to ensure that the support plate 120 can move accurately in place. Specifically, the first limiting member 161 and the second limiting member 162 can be in a block shape, a plate shape or a rod shape, and can be arranged on the support plate 120, or can be arranged on the fixing plate 150 or other support structures (not shown in the figure).

[0091] In this embodiment, the automatic plugging and unplugging device 100 further includes a third limiter 163 and a fourth limiter 164 , and the lifting frame 130 can move along the second direction within the range defined by the third limiter 163 and the fourth limiter 164 .

[0092] The third stopper 163 cooperates with the fourth stopper 164 to control the stroke of the second driving member 140, thereby ensuring that the lifting frame 130 can be accurately moved to the position. Similarly, the third stopper 163 and the fourth stopper 164 can also be block-shaped, plate-shaped or rod-shaped, and can be set on the support plate 120 or the lifting frame 130.

[0093] The steps of performing the aging test by the aging test equipment 10 include a pre-test preparation step, a temperature control test step, and a post-test separation step.

[0094] In the pre-test preparation steps, the pre-push drive component 220 drives the pre-push component 210 to push the BIB unit board 20 on the carrier 30 to a preset position according to the push-in instruction; the automatic plug-in device 100 pulls the BIB unit board 20 at the preset position toward the signal board 410 according to the docking instruction until the BIB unit board 20 is plugged into the signal board 410; the chamber door drive mechanism 320 drives the door panel 310 to close the entrance and exit according to the door closing instruction to form a sealed environment in the test chamber.

[0095] The temperature control test step controls the preset temperature in the test chamber according to the test instructions, and provides a test signal to the BIB unit board 20 through the signal board 410 to complete the aging test.

[0096] In the post-test separation step, the cavity door driving mechanism 320 drives the door plate 310 to open the inlet and outlet according to the door opening instruction; the automatic plug-in and unplug device 100 pushes the BIB unit board 20 away from the signal board 410 according to the separation instruction until the BIB unit board 20 is separated from the signal board 410.

[0097] Furthermore, in the pre-test preparation step, the pre-push component 210 pushes the BIB unit board 20 on the carrier 30 to a preset position and maintains the pre-push state. Moreover, in the test separation step, when the automatic plug-in device 100 pushes the BIB unit board 20 away from the signal board 410, the pre-push drive component 220 can also drive the pre-push component 210 to switch to the avoidance state according to the push-out instruction.

[0098] The above-mentioned aging test equipment 10 is generally controlled by a host computer to perform aging test operations, and the cavity door device 300, the pre-pushing device 200 and the automatic plug-in device 100 are all connected to the above-mentioned host computer in communication. The above-mentioned push-in instructions, docking instructions, door closing instructions, test instructions, door opening instructions, separation instructions and push-out instructions can all be generated and issued by the host computer, thereby controlling the cavity door device 300, the pre-pushing device 200 and the automatic plug-in device 100 to automatically perform corresponding operations. In addition, the operator can also interact with input devices such as buttons and touch screens to generate the above-mentioned instructions.

[0099] The pre-test preparation steps, temperature control test steps and post-test separation steps are performed in sequence, and after completing the previous round of testing, the pre-push drive assembly 220 is in an avoidance state, and the door panel 310 opens the inlet and outlet, so the carrier 30 equipped with the next round of BIB unit boards 20 to be tested can be placed in the test chamber, thereby quickly connecting to the next round of pre-test preparation steps.

[0100] The above-mentioned aging test equipment 10 can automatically execute the pre-test preparation steps, temperature control test steps and post-test separation steps according to the corresponding instructions. After completing the previous round of aging test, the chamber door drive mechanism 320 drives the door panel 310 to open the inlet and outlet, and the pre-push drive component 320 drives the pre-push component 310 to switch to the avoidance state. At this time, the carrier 30 and the BIB unit board 20 can be taken out through the inlet and outlet, so as to realize the unloading of the chips that have completed the test. Then, the BIB unit board 20 loaded with the chip to be tested is placed on the carrier 30, and the carrier 30 is placed into the test cavity through the inlet and outlet, and the pre-test preparation steps can be connected to carry out the next round of aging test. It can be seen that the above-mentioned aging test equipment 10 has a high degree of automation, and can realize multiple rounds of tests in sequence, thereby significantly improving the efficiency of the aging test.
