[0002] Semiconductor memories have a failure probability, and the probability conforms to the characteristics of a bathtub curve with the number of uses, that is, after a certain number of uses of the semiconductor memory, its failure probability decreases, and the failure probability will only increase when the life is approaching. The prior art provides a power signal and a test signal to an IC (integrated circuit) that has completed packaging and testing at high or low temperature or normal temperature conditions, and makes the IC continuously work within a short time, so that the IC quickly enters a performance stable period.
[0003] A BIB (Burn-in Board) is a carrier for aging tests of semiconductor ICs, and multiple aging test boards are loaded on a carrier frame. Each aging test board on the carrier frame is automatically inserted into a plug connector on a test mechanism through an insertion mechanism, so that the test mechanism performs aging tests on the ICs on the aging test boards. However, since there is a situation where the position of the aging test board on the carrier frame is not in place, it is easy to have phenomena such as the insertion mechanism not being able to hook the aging test board or the aging test board slipping during automatic insertion. Summary of the Utility Model
[0004] Based on this, in view of the problem in the prior art that due to the situation where the position of the aging test board on the carrier frame is not in place, it is easy to have phenomena such as the insertion mechanism not being able to hook the aging test board or the aging test board slipping during automatic insertion, it is necessary to provide a pre-pushing mechanism and an aging test device that improve the above defects.
[0005] A pre-pushing mechanism includes:

[0008] Wherein, during the process that the driving assembly drives the mounting frame to move towards the carrier frame relative to the frame, the driving part drives the pre-pushing frame to unfold relative to the mounting frame in a direction close to the carrier frame, so that the pre-pushing frame pushes each aging test board on the carrier frame to a preset position.
[0009] In one embodiment, during the process that the driving assembly drives the mounting rack to move away from the bearing rack relative to the machine frame, the driving part drives the pre-pushing rack to close in a direction away from the bearing rack relative to the mounting rack, so as to allow the bearing rack to enter and exit the accommodation space of the machine frame.

[0013] In one embodiment, the pre-pushing rack includes a second rotating shaft, a second connecting piece and a pre-pushing rod. The second rotating shaft is rotatably connected to the first connecting piece around its own axis and is linked with the first rotating shaft through the driving part, and the pre-pushing rod is fixedly connected to the second rotating shaft through the second connecting piece.
[0014] In one embodiment, the mounting rack can rotate relative to the machine frame to an avoidance position; when the mounting rack is in the avoidance position, the first rotating shaft drives the second rotating shaft to rotate to the side of the first rotating shaft away from the machine frame through the first connecting piece, and the second rotating shaft drives the pre-pushing rod to rotate between the first rotating shaft and the second rotating shaft through the second connecting piece.
[0015] In one embodiment, the machine frame further has an entrance and exit for the bearing rack to enter and exit the accommodation space;
[0016] The mounting rack can rotate relative to the machine frame to a pre-pushing position; when the mounting rack is in the pre-pushing position, the first rotating shaft drives the second rotating shaft to rotate to the entrance and exit through the first connecting piece, and the second rotating shaft drives the pre-pushing rod to rotate to the side of the second rotating shaft facing the bearing rack through the second connecting piece.
[0017] In one embodiment, the driving unit includes a first gear, a second gear and a third gear;

[0035] Please refer to Figure 1 , an embodiment of the present utility model provides an aging test device, including a test mechanism, a mating mechanism and a pre-pushing mechanism. The pre-pushing mechanism is used to accommodate a carrier 200, and the carrier 200 is used to load a plurality of aging test boards 300. The test mechanism is arranged on one side of the pre-pushing mechanism, and the side of the test mechanism facing the pre-pushing mechanism has a plurality of sockets. The pre-pushing mechanism is also used to pre-push each aging test board 300 on the carrier 200, so that each aging test board 300 on the carrier 200 moves towards the test mechanism to a preset position respectively. The mating mechanism is arranged between the pre-pushing mechanism and the test mechanism, and is used to respectively mate each aging test board 300 in the preset position on the carrier 200 with each socket on the test mechanism. That is to say, before the mating mechanism mates each aging test board 300 with each socket on the test mechanism, the pre-pushing mechanism is used to pre-push each aging test board 300 on the carrier 200, so as to ensure that each aging test board 300 on the carrier 200 reaches the preset position before mating, and ensure that the mating mechanism can accurately mate each aging test board 300 with each socket on the test mechanism, avoiding phenomena such as the mating mechanism not being able to hook the aging test board 300 or the aging test board 300 slipping off.
[0036] Please see Figures 1 to 3 , in the embodiment of the present application, the pre-pushing mechanism includes a frame 10 and a pre-pushing unit 20. The frame 10 has a receiving space for accommodating the carrier 200, and the carrier 200 is used to load a plurality of aging test boards 300. The pre-pushing unit 20 (see Figure 3)It includes a folding component 21 and a driving component 22. The folding component 21 includes a mounting bracket 211 (see Figure 3 ), a driving part 212 and a pre-pushing bracket 213 (see Figure 3 ). The mounting bracket 211 is movably connected to the frame 10, and the driving component 22 is drivingly connected to the mounting bracket 211 so that the driving component 22 can drive the mounting bracket 211 to move relative to the frame 10. The pre-pushing bracket 213 is movably mounted on the mounting bracket 211, and the driving part 212 is connected between the mounting bracket 211 and the pre-pushing bracket 213 so that the driving part 212 can drive the pre-pushing bracket 213 to move relative to the mounting bracket 211. Wherein, when the driving component 22 drives the mounting bracket 211 to move relative to the frame 10 towards the carrier 200 in the receiving space, the driving part 212 drives the pre-pushing bracket 213 to move and unfold relative to the mounting bracket 211 in the direction close to the carrier 200 in the receiving space, so that the pre-pushing bracket 213 pushes each aging test board 300 on the carrier 200 to a preset position.
[0037] Thus, in actual use, first, place the carrier 200 in the receiving space of the frame 10; then, the driving component 22 drives the mounting bracket 211 to move relative to the frame 10, so that the mounting bracket 211 drives the pre-pushing bracket 213 to gradually approach the carrier 200 in the receiving space; at the same time, the driving part 212 drives the pre-pushing bracket 213 to unfold relative to the mounting bracket 211 towards the carrier 200 in the receiving space, so that the pre-pushing bracket 213 approaches the carrier 200 in the receiving space more quickly until the pre-pushing bracket 213 pushes each aging test board 300 on the carrier 200 to a preset position, avoiding the existence of aging test boards 300 that are not in place on the carrier 200, ensuring that the plugging mechanism can accurately plug each aging test board 300 onto each plug on the test mechanism, and avoiding phenomena such as the plugging mechanism not being able to hook the aging test board 300 or the aging test board 300 slipping.
[0038] It should be noted that the preset position refers to the in-place position where each aging test board 300 is inserted onto the carrier 200. When the aging test board 300 is at the preset position on the carrier 200, the plugging mechanism can hook it to be plugged with each plug on the test mechanism. When inserting each aging test board 300 onto the carrier 200, there is a situation where the insertion is not in place, that is, there is a situation where the aging test board 300 does not reach the preset position. In this application, the pre-pushing bracket 213 is used to pre-push each aging test board 300 on the carrier 200 to ensure that each aging test board 300 on the carrier 200 is in the preset position (that is, all are inserted in place).
[0039] In some embodiments, the rack 10 further has an entrance / exit 11 for the carrier 200 to enter and exit the accommodation space. When the driving assembly 22 drives the mounting frame 211 to move relative to the rack 10 in a direction away from the carrier 200 in the accommodation space, the driving part 212 drives the pre-pushing frame 213 to fold relative to the mounting frame 211 in a direction away from the carrier 200 in the accommodation space until both the mounting frame 211 and the pre-pushing frame 213 do not block the entrance / exit 11 of the rack 10, so as to allow the carrier 200 to enter and exit the accommodation space of the rack 10 through the entrance / exit 11. Thus, during actual use, first, the driving assembly 22 drives the mounting frame 211 to move relative to the rack 10 in a direction away from the entrance / exit 11. At the same time, the driving part 212 drives the pre-pushing frame 213 to move and fold relative to the mounting frame 211 in a direction away from the entrance / exit 11 until both the mounting frame 211 and the pre-pushing frame 213 do not block the entrance / exit 11 of the rack 10. Then, the carrier 200 loaded with the aging test board 300 is sent into the accommodation space of the rack 10 through the entrance / exit 11. Then, the driving assembly 22 drives the mounting frame 211 to move relative to the rack 10 towards the entrance / exit 11 of the rack 10, so that the mounting frame 211 and the pre-pushing frame 213 on the mounting frame 211 gradually approach the carrier 200 in the accommodation space. At the same time, the driving part 212 drives the pre-pushing frame 213 to move and unfold relative to the mounting frame 211 in a direction towards the carrier 200, so that the pre-pushing frame 213 gradually approaches the carrier 200 until each aging test board 300 on the carrier 200 is pushed to a preset position.
[0040] It should also be noted that when the driving assembly 22 drives the mounting frame 211 to move closer to the carrier 200 in the accommodation space, so that the mounting frame 211 drives the pre-pushing frame 213 to move closer to the carrier 200 in the accommodation space, the pre-pushing frame 213 moves and unfolds relative to the mounting frame 211 towards the carrier 200. This enables the mounting frame 211 to drive the pre-pushing frame 213 to push each aging test board 300 on the carrier 200 to a preset position with a relatively small stroke. On the one hand, it is beneficial to save the space occupied by the folding assembly 21 and improve space utilization; on the other hand, it is beneficial to improve the response speed of the folding assembly 21, shorten the time required for the pre-pushing action, and improve production efficiency. Similarly, when the driving assembly 22 drives the mounting frame 211 to move away from the carrier 200 in the accommodation space, so that the mounting frame 211 drives the pre-pushing frame 213 to move away from the carrier 200 in the accommodation space, the pre-pushing frame 213 folds relative to the mounting frame 211 in a direction away from the carrier 200. This enables the mounting frame 211 to drive the pre-pushing frame 213 and the pre-pushing frame 213 to move away from the entrance / exit 11 of the rack 10 with a relatively small stroke to avoid blocking the entrance / exit 11. On the one hand, it is beneficial to save the space occupied by the folding assembly 21 and improve space utilization; on the other hand, it is beneficial to improve the response speed of the folding assembly 21 and shorten the time required for the return journey after the pre-pushing action is completed, and improve production efficiency.
[0041] Furthermore, the mounting frame 211 is rotatably connected to the frame 10, and the driving assembly 22 is used to drive the mounting frame 211 to rotate relative to the frame 10, so that the mounting frame 211 drives the pre-pushing frame 213 to approach or move away from the carrier frame 200 in the receiving space. The pre-pushing frame 213 is rotatably connected to the mounting frame 211, and is linked with the mounting frame 211 through the driving unit 212, so that when the mounting frame 211 rotates relative to the frame 10, the pre-pushing frame 213 rotates relative to the mounting frame 211 to expand or retract. In this way, only one power source of the driving assembly 22 is used to realize the rotation of the mounting frame 211 relative to the frame 10 and the rotation of the pre-pushing frame 213 relative to the mounting frame 211, which reduces the number of power sources, reduces the cost of the device, and saves the required space.
[0042] Specifically in the embodiment, the mounting frame 211 includes a first rotating shaft 2113 and a first connecting member 2115. The first rotating shaft 2113 is rotatably connected to the frame 10 around its own axis, and is drivingly connected to the driving assembly 22, so that the driving assembly 22 can drive the first rotating shaft 2113 to rotate around its own axis relative to the frame 10. The first connecting member 2115 is fixedly connected to the first rotating shaft 2113, and the pre-pushing frame 213 is rotatably connected to the first connecting member 2115, and is linked with the first rotating shaft 2113 through the driving part 212, so that when the driving assembly 22 drives the first rotating shaft 2113 to rotate, the driving part 212 can drive the pre-pushing frame 213 to rotate relative to the first connecting member 2115. Thus, in actual use, first, the driving assembly 22 drives the first rotating shaft 2113 to rotate, so that the first rotating shaft 2113 drives the pre-pushing frame 213 to enter the entrance 11 of the frame 10 through the first connecting member 2115, so as to drive the pre-pushing frame 213 close to the carrier 200 in the receiving space. At the same time, the driving unit 212 drives the pre-pushing frame 213 to rotate relative to the first connecting member 2115, so that the pre-pushing frame 213 rotates and unfolds relative to the mounting frame 211 in the direction close to the carrier 200 in the receiving space, until the pre-pushing frame 213 pushes each aging test board 300 on the carrier 200 to a preset position. After the pre-pushing is completed, the driving assembly 22 drives the first rotating shaft 2113 to rotate in the opposite direction, so that the first rotating shaft 2113 drives the pre-pushing frame 213 to exit the entrance 11 of the frame 10 through the first connecting member 2115, so as to drive the pre-pushing frame 213 away from the carrier 200 in the receiving space. At the same time, the driving unit 212 drives the pre-pushing frame 213 to rotate in the opposite direction relative to the first connecting member 2115, so that the pre-pushing frame 213 rotates away from the supporting frame 200 in the receiving space, so that the pre-pushing frame 213 is folded and retracted relative to the mounting frame 211 until the supporting frame 200 can enter and exit the receiving space of the frame 10 through the entrance 11.
[0043] Further, the pre-pushing frame 213 includes a second rotating shaft 2131, a second connecting member 2133 and a pre-pushing rod 2135. The second rotating shaft 2131 is rotatably connected to the first connecting member 2115 around its own axis, and is linked with the first rotating shaft 2113 through the driving unit 212, so that when the first rotating shaft 2113 rotates, it can drive the second rotating shaft 2131 to rotate. The pre-pushing rod 2135 is fixedly connected to the second rotating shaft 2131 through the second connecting member 2133, so that when the second rotating shaft 2131 rotates, it can drive the pre-pushing rod 2135 to rotate, thereby realizing the folding, folding or unfolding of the pre-pushing frame 213 relative to the mounting frame 211. In this way, first, the driving component 22 drives the first rotating shaft 2113 to rotate, so that the first rotating shaft 2113 drives the pre-pushing rod 2135 to enter the entrance 11 of the frame 10, so as to drive the pre-pushing rod 2135 to approach the carrier 200 in the receiving space. At the same time, the driving unit 212 drives the second rotating shaft 2131 to rotate relative to the first connecting member 2115, so that the second rotating shaft 2131 drives the pre-pushing rod 2135 to expand relative to the first connecting member 2115 in the direction close to the carrier 200 in the receiving space, until the pre-pushing rod 2135 pushes each aging test board 300 on the carrier 200 to a preset position. After the pre-pushing is completed, the driving assembly 22 drives the first rotating shaft 2113 to rotate in the opposite direction, so that the first rotating shaft 2113 drives the pre-pushing rod 2135 to exit the entrance 11 of the frame 10 through the first connecting member 2115, that is, the pre-pushing rod 2135 gradually moves away from the carrier 200 in the receiving space. At the same time, the driving unit 212 drives the second rotating shaft 2131 to rotate in the opposite direction relative to the first connecting member 2115, so that the second rotating shaft 2131 drives the pre-push rod 2135 to rotate away from the supporting frame 200 in the accommodating space through the second connecting member 2133, so that the pre-push rod 2135 is folded and retracted relative to the mounting frame 211.
[0044] Specifically in the embodiment, the mounting frame 211 can be rotated to the avoidance position and the pre-pushing position relative to the frame 10. Figure 1 ), the first rotating shaft 2113 drives the second rotating shaft 2131 to rotate away from the entrance 11 of the frame 10 through the first connecting member 2115, until the second rotating shaft 2131 reaches the side of the first rotating shaft 2113 away from the frame 10; at the same time, the second rotating shaft 2131 drives the pre-pushing rod 2135 to rotate to between the first rotating shaft 2113 and the second rotating shaft 2131 through the second connecting member 2133 (that is, the pre-pushing frame 213 is retracted relative to the mounting frame 211), so that the mounting frame 211 and the pre-pushing frame 213 both withdraw from the entrance 11 of the frame 10, that is, the mounting frame 211 and the pre-pushing frame 213 do not block the entrance 11 of the frame 10, so that the carrier frame 200 can enter and exit the accommodating space of the frame 10 through the entrance 11.
[0045] When the mounting bracket 211 rotates to the pre-pushing position (see Figure 2 ), the first rotating shaft 2113 drives the second rotating shaft 2131 to rotate to the entrance and exit 11 through the first connecting member 2115, and the second rotating shaft 2131 drives the pre-pushing rod 2135 to rotate to the side of the second rotating shaft 2131 facing the carrier 200 (i.e., the pre-pushing frame 213 expands relative to the mounting bracket 211) through the second connecting member 2133, so that the pre-pushing rod 2135 pushes each aging test board 300 on the carrier 200 to the preset position.
[0046] Optionally, a plurality of fixing brackets 214 are fixedly installed on the frame 10, and the first rotating shaft 2113 is installed on each fixing bracket 214 through bearings, so that the first rotating shaft 2113 is rotatable relative to the frame 10. It should be noted that in some other embodiments, the first rotating shaft 2113 is installed on each fixing bracket 214 through an oil-free bushing, or the first rotating shaft 2113 is installed on each fixing bracket 214 in a way of inserting and matching the shaft and the hole, as long as the first rotating shaft 2113 can be rotatable relative to each fixing bracket 214, which is not limited herein.
[0047] It should be noted that the number of the pre-pushing frames 213 can be one. Of course, in other embodiments, the number of the pre-pushing frames 213 can also be at least two. The second rotating shaft 2131 of each pre-pushing frame 213 is installed on the corresponding first connecting member 2115 through bearings, and the second rotating shafts 2131 of the respective pre-pushing frames 213 are arranged at intervals along the axial direction of the first rotating shaft 2113. The pre-pushing rod 2135 of each pre-pushing frame 213 is fixedly connected to the second rotating shaft 2131 through the second connecting member 2133. In this way, the pre-pushing rod 2135 of each pre-pushing frame 213 can pre-push the corresponding part of the aging test board 300 on the carrier 200, so as to ensure that all the aging test boards 300 on the carrier 200 can be pre-pushed.
[0048] Further, two first connectors 2115 are correspondingly arranged for the second rotation shaft 2131 of each pre-pushing frame 213. One end of the second rotation shaft 2131 is mounted on one of the first connectors 2115 through a bearing, and the other end of the second rotation shaft 2131 is mounted on the other first connector 2115 through a bearing. Each pre-pushing frame 213 includes two second connectors 2133. One end of the pre-pushing rod 2135 is fixedly connected to one of the second connectors 2133, and the other end of the pre-pushing rod 2135 is fixedly connected to the other second connector 2133. It should be noted that in some other embodiments, the second rotation shaft 2131 is mounted on the corresponding first connector 2115 through an oil-free bushing, or the second rotation shaft 2131 is mounted on the corresponding first connector 2115 by means of insertion fit of a shaft and a hole, as long as the second rotation shaft 2131 can rotate relative to the first connector 2115, which is not limited herein.
[0049] It should be noted that the number of pre-pushing frames 213 can be set according to the height of the carrier 200. The higher the height of the carrier 200, the more pre-pushing frames 213 can be set. The lower the height of the carrier 200, the fewer pre-pushing frames 213 can be set, as long as it is ensured that all the aging test boards 300 on the carrier 200 can be pre-pushed, which is not limited herein.
[0050] Optionally, two pre-pushing units 20 are provided, and the two pre-pushing units 20 are respectively arranged on opposite sides of the entrance 11 of the frame 10. Thus, in actual use, first, the two driving components 22 respectively drive the first rotating shafts 2113 of the two folding components 21 to rotate, thereby driving the second rotating shafts 2131 of the two folding components 21 to rotate in a direction away from each other to open the entrance 11, until the second rotating shafts 2131 of the two folding components 21 are located outside the range of the entrance and exit of the frame 10, that is, the entrance and exit 11 of the frame 10 is not blocked (at this time, the mounting frame 211 is in an avoidance position). At the same time, the second rotating shafts 2131 of the two folding components 21 drive the pre-pushing rod 2135 to rotate and retract to the position between the first rotating shaft 2113 and the second rotating shaft 2131, that is, the space between the first rotating shaft 2113 and the second rotating shaft 2131 is used to accommodate the pre-pushing rod 2135, so as to prevent the pre-pushing rod 2135 from blocking the entrance 11, so that the carrier 200 can enter and exit the receiving space through the entrance 11 of the frame 10. Then, the carrier 200 is placed into the receiving space of the frame 10 through the entrance 11. Then, the two driving components 2223 respectively drive the second rotating shafts 2131 of the two folding components 21 to rotate, thereby driving the second rotating shafts 2131 of the two folding components 21 to rotate in a direction close to each other (that is, entering the range of the entrance 1111 of the frame 10). At the same time, the second rotating shafts 2131 of the two folding components 21 drive the pre-pushing rods 2135 to rotate and unfold towards the direction close to the supporting frame 200 until the pre-pushing rods 2135 of the two folding components 21 jointly push each aging test board 300 on the supporting frame 200 to a preset position.
[0051] It should be noted that the pre-push rods 2135 of the two folding components 21 are used to jointly push the various aging test boards 300 on the carrier 200 from the opposite sides of the entrance and exit 11, so that the pushing of each aging test board 300 is more stable and reliable, and the deflection of each aging test board 300 during the pushing process is avoided.
[0052] See also Figure 4As shown, specifically in the embodiment, the driving part 212 includes a first gear 2123, a second gear 2125 and a third gear 2127. The first gear 2123 is fixedly connected to the frame 10 and is coaxial with the first rotating shaft 2113. The second gear 2125 is fixedly connected to the second rotating shaft 2131 and is coaxial with the second rotating shaft 2131. The third gear 2127 is rotatably connected to the first connecting member 2115 and meshes between the first gear 2123 and the second gear 2125. In this way, when the driving assembly 22 drives the first rotating shaft 2113 to rotate, the first rotating shaft 2113 drives the second rotating shaft 2131 to revolve around the first rotating shaft 2113 through the first connecting member 2115, and the first connecting member 2115 drives the third gear 2127 to revolve around the first gear 2123. Since the first gear 2123 meshes with the third gear 2127, the first gear 2123 drives the third gear 2127 to rotate on its own axis; since the third gear 2127 meshes with the second gear 2125, the third gear 2127 drives the second gear 2125 to rotate on its own axis, and the second gear 2125 then drives the second rotating shaft 2131 to rotate, and the second rotating shaft 2131 then drives the pre-pushing rod 2135 to rotate around the second rotating shaft 2131 through the second connecting member 2133, so as to realize the rotational unfolding or closing of the pre-pushing frame 213 relative to the mounting frame 211.
[0053] That is to say, when the first rotating shaft 2113 rotates around its own axis, on the one hand, the first rotating shaft 2113 drives the pre-pushing rod 2135 to rotate around the first rotating shaft 2113 through the first connecting member 2115, the second rotating shaft 2131 and the second connecting member 2133; on the other hand, the linkage between the second rotating shaft 2131 and the first rotating shaft 2113 is realized by using the first gear 2123, the second gear 2125 and the third gear 2127, that is, the rotational movement of the first rotating shaft 2113 around its own axis is converted into the rotational movement of the second rotating shaft 2131 around its own axis, and the second rotating shaft 2131 then drives the pre-pushing rod 2135 to rotate around the second rotating shaft 2131 through the second connecting member 2133.
[0054] It should be noted that the driving part 212 is not limited to adopting the above gear transmission structure. In some other embodiments, the driving part 212 can also be a rotary driving part (the rotary driving part can adopt a motor) arranged on the first connecting member 2115, and the rotary driving part is drivingly connected to the second rotating shaft 2131 to drive the second rotating shaft 2131 to rotate around its own axis relative to the first connecting member 2115, so as to realize that the pre-pushing rod 2135 rotates around the first rotating shaft 2113 and also rotates around the second rotating shaft 2131 at the same time, which is not limited here.
[0055] Please refer to Figure 3 and Figure 5, in the embodiments of the present application, the driving assembly 22 includes a fixed seat 221, a telescopic member 223, a connecting seat 225 and an adapter 227. The telescopic member 223 has a body 2235 and a telescopic end 2237 that is telescopic relative to the body 2235. The body 2235 of the telescopic member 223 is hinged to the fixed seat 221, the adapter 227 is fixedly connected to the first rotating shaft 2113, the telescopic end 2237 of the telescopic member 223 is hinged to the connecting seat 225, and the connecting seat 225 is hinged to the adapter 227. When the telescopic end 2237 of the telescopic member 223 telescopes relative to the body 2235, it can drive the first rotating shaft 2113 to rotate about its own axis through the connecting seat 225 and the adapter 227. Optionally, the telescopic member 223 can be a cylinder.
[0056] Thus, when the telescopic end 2237 of the telescopic member 223 retracts relative to the body 2235, the telescopic end 2237 drives the first rotating shaft 2113 to rotate through the connecting seat 225 and the adapter 227, and the first rotating shaft 2113 then drives the second rotating shaft 2131 to rotate away from the entrance / exit 11 of the frame 10. At the same time, the second rotating shaft 2131 drives the pre-pushing rod 2135 to rotate towards the space between the first rotating shaft 2113 and the second rotating shaft 2131 until both the second rotating shaft 2131 and the pre-pushing rod 2135 are outside the range of the entrance / exit 11 of the carrier 200, so that the carrier 200 can enter and exit the receiving space of the frame 10 through the entrance / exit 11.
[0057] When the telescopic end 2237 of the telescopic member 223 extends relative to the body 2235, the telescopic end 2237 drives the first rotating shaft 2113 to rotate through the connecting seat 225 and the adapter 227, and the first rotating shaft 2113 then drives the second rotating shaft 2131 to rotate towards the entrance / exit 11 of the frame 10. At the same time, the second rotating shaft 2131 drives the pre-pushing rod 2135 to rotate towards the carrier 200 in the receiving space until the pre-pushing rod 2135 pushes each aging test board 300 on the carrier 200 to a preset position.
[0058] Further, the pre-pushing unit 20 further includes a sensing member 229 and a detecting member. The sensing member 229 is disposed on the connecting seat 225 such that the sensing member 229 moves together with the connecting seat 225. The detecting member is configured to detect the position of the sensing member 229 and determine whether the telescopic end 2237 of the telescopic member 223 extends or retracts relative to the main body 2235. Thus, when the detecting member detects the sensing member 229, it indicates that the telescopic end 2237 of the telescopic member 223 retracts relative to the main body 2235. At this time, the second rotating shaft 2131 and the pre-pushing rod 2135 are outside the range of the entrance / exit 11 of the frame 10, and the pre-pushing rod 2135 rotates and folds relative to the mounting bracket 211 to between the first rotating shaft 2113 and the second rotating shaft 2131, so that the carrier 200 can enter and exit the accommodation space of the frame 10 through the entrance / exit 11. When the detecting member does not detect the sensing member 229, it indicates that the telescopic end 2237 of the telescopic member 223 extends relative to the main body 2235. At this time, the second rotating shaft 2131 and the pre-pushing rod 2135 are within the range of the entrance / exit 11 of the frame 10, and the pre-pushing rod 2135 rotates and unfolds relative to the mounting bracket 211 to the side where the second rotating shaft 2131 faces the carrier 200, and pushes each aging test board 300 on the carrier 200 to a preset position. Optionally, the detecting member may be an optoelectronic sensor.
