[0034] Please refer to Figure 1 and Figure 2 , 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 plug connectors. 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 to each plug connector on the test mechanism. That is to say, before the mating mechanism mates each aging test board 300 to each plug connector 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 is in the preset position before mating, and ensure that the mating mechanism can accurately mate each aging test board 300 to each plug connector 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.
[0035] In an 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 receiving the carrier 200. The pre-pushing unit 20 includes a pre-pushing assembly 21 and a driving assembly 23. The pre-pushing assembly 21 is movably connected to the frame 10 and has a push rod 213. The driving assembly 23 is drivingly connected to the pre-pushing assembly 21 and is used to drive the pre-pushing assembly 21 to move relative to the frame 10, so as to drive the push rod 213 to push each aging test board 300 on the carrier 200 to a preset position. Thus, in actual use, first, the carrier 200 is placed in the receiving space of the frame 10; then, the driving assembly 23 drives the pre-pushing assembly 21 to move relative to the frame 10 until the push rod 213 of the pre-pushing assembly 21 pushes each aging test board 300 on the carrier 200 to the preset position, avoiding the situation that there are aging test boards 300 that are not inserted 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 off.
[0036] 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 in 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 may be a situation where the insertion is not in place, that is, the aging test board 300 does not reach the preset position. In the present application, the pre-pushing assembly 21 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.
[0037] In some embodiments, the driving assembly 23 is used to drive the pre-pushing assembly 21 to move relative to the frame 10 to the avoidance state (see Figure 1 ) and the pre-pushing state (see Figure 2The rack 10 also has an entrance 11 for the carrier 200 to enter and exit the accommodation space. When the pre-pushing assembly 21 is in the avoidance state, the pre-pushing assembly 21 allows the carrier 200 to enter and exit the accommodation space of the rack 10 through the entrance 11. When the pre-pushing assembly 21 is in the pre-pushing state, the push rod 213 of the pre-pushing assembly 21 pushes each aging test board 300 on the carrier 200 to a preset position at the entrance 11. In this way, in actual use, first, the driving component 23 drives the pre-pushing component 21 to move to an avoidance state relative to the frame 10, so that the pre-pushing component 21 does not block the entrance and exit 11 of the frame 10; then, the driving component 23 drives the pre-pushing component 21 to move relative to the frame 10, thereby gradually approaching the side of the carrier 200 located at the entrance and exit 11 of the frame 10, until the push rod 213 of the pre-pushing component 21 moves each aging test board 300 on the carrier 200 to a preset position at the entrance and exit 11 of the frame 10, at which time the pre-pushing component 21 is in a pre-pushing state.
[0038] See also Figures 1 to 3 In some embodiments, the pre-pushing assembly 21 includes a rotating shaft 211 and a connecting member 212. The rotating shaft 211 is rotatably connected to the frame 10, and the push rod 213 is fixedly connected to the rotating shaft 211 through the connecting member 212. The driving assembly 23 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 then the push rod 213 pushes each aging test board 300 on the carrier 200 to a preset position.
[0039] Furthermore, when the pre-push component 21 is in the avoidance state, under the driving action of the driving component 23, the rotating shaft 211 drives the push rod 213 to rotate outside the range of the entrance and exit 11 of the frame 10, so that the carrier 200 can smoothly enter the accommodating space from the entrance and exit 11 of the frame 10.
[0040] The connecting member 212 has a stopper. When the pre-pushing assembly 21 is in the pre-pushing state, under the driving action of the driving assembly 23, the rotating shaft 211 drives the push rod 213 to rotate to the entrance 11 of the rack 10, so that the push rod 213 pushes each aging test board 300 on the carrier 200 to move to a preset position relative to the carrier 200. At this time, the stopper on the connecting member 212 cooperates with the stopper of the carrier 200, thereby preventing the carrier 200 from retreating from the entrance 11 of the rack 10.
[0041] 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, the push rod 213 can be driven to rotate through the connecting member 212. When the pre-pushing assembly 21 is in the pre-pushing state, the end of the connecting member 212 connected to the push rod 213 is closer to the carrier 200 in the receiving space than the end of the connecting member 212 connected to the rotating shaft 211. When the pre-pushing assembly 21 is in the avoidance state, the end of the connecting member 212 connected to the push rod 213 is farther away from the carrier 200 in the receiving space than the end of the connecting member 212 connected to the rotating shaft 211.
[0042] Optionally, the pre-pushing assembly 21 further includes a plurality of fixed seats 210 and a plurality of bearings, and each fixed seat 210 is fixedly connected to the frame 10. The rotating shaft 211 is respectively mounted on each fixed seat 210 through each bearing, so that the rotating shaft 211 can rotate around its own axis relative to the frame 10 and each fixed seat 210. It should be noted that in other embodiments, the rotating shaft 211 is mounted on each fixed seat 210 through an oil-free bushing, or the rotating shaft 211 is mounted on each fixed seat 210 through a shaft-hole plug-in fit, as long as the rotating shaft 211 can be rotatable relative to each fixed seat 210, it is not limited here.
[0043] It should be noted that the pre-pushing assembly 21 may include a push rod 213. Of course, in other embodiments, the pre-pushing assembly 21 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 fixedly connected to the rotating shaft 211 through their respective corresponding connecting members 212. In this way, the rotating shaft 211 can simultaneously drive each push rod 213 to rotate, so that each push rod 213 can pre-push the corresponding part of the aging test board 300 on the carrier 200, thereby ensuring that all the aging test boards 300 on the carrier 200 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 200. The higher the height of the carrier 200, the more push rods 213 can be set, and the lower the height of the carrier 200, the fewer push rods 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, and no limitation is made here.
[0044] Optionally, the longitudinal ends of each push rod 213 are respectively fixedly connected to the rotating shaft 211 through corresponding connecting pieces 212, so that the push rod 213 is more stable and prevents the push rod 213 from shaking or deforming when pushing the aging test board 300. Of course, in other embodiments, the middle part of each push rod 213 can also be fixed to the rotating shaft 211 through corresponding connecting pieces 212, as long as the push rod 213 is installed more stably, which is not limited here.
[0045] Specifically in the embodiment, two pre-pushing units 20 are provided, and the two pre-pushing units 20 are respectively arranged on opposite sides of the entrance and exit 11 of the frame 10. Thus, in actual use, first, the two driving components 23 respectively drive the rotating shafts 211 of the two pre-pushing components 21 to rotate, thereby driving the push rods 213 of the two pre-pushing components 21 to rotate and open in a direction away from each other, until the push rods 213 of the two pre-coating components are located outside the range of the entrance and exit 11 of the frame 10, that is, the entrance and exit 11 of the frame 10 are not blocked (at this time, the two pre-pushing components 21 are in a evasive state), so that the carrier 200 can enter and exit the receiving space through the entrance and exit 11 of the frame 10. Then, the carrier 200 is placed in the receiving space through the entrance and exit 11. Then, the two driving components 23 respectively drive the rotating shafts 211 of the two pre-pushing components 21 to rotate, thereby driving the push rods 213 of the two pre-pushing components 21 to rotate in a direction approaching each other (i.e. entering into the range of the entrance and exit 11 of the frame 10), and then the push rods 213 of the two pre-pushing components 21 gradually approach the respective aging test boards 300 on the carrier 200, until they jointly push the respective aging test boards 300 on the carrier 200 to a preset position.
[0046] It should be noted that the push rods 213 of the two pre-push assemblies 21 are used to jointly push the aging test boards 300 on the carrier 200 from the opposite sides of the entrance and exit 11, so that the pushing of the aging test boards 300 is more stable and reliable, and the deflection of the aging test boards 300 during the movement is avoided.
[0047] In an embodiment of the present application, the driving assembly 23 includes a mounting seat 232, a telescopic member 231 and an adapter block 233. The telescopic member 231 has a mounting end a1 and a telescopic end a2 opposite to the mounting end a1. The telescopic end a2 can be controlled to telescope relative to the mounting end a1. The adapter block 233 is fixedly connected to the rotating shaft 211, the mounting end a1 of the telescopic member 231 is hinged to the mounting seat 232, and the telescopic end a2 of the telescopic member 231 is hinged to the adapter block 233. When the telescopic end a2 of the telescopic member 231 telescopes relative to the mounting end a1, the rotating shaft 211 can be driven to rotate around its own axis through the adapter block 233. Optionally, the telescopic member 231 can adopt a cylinder.
[0048] In this way, when the telescopic end a2 of the telescopic member 231 extends relative to the mounting end a1, the telescopic end a2 drives the rotating shaft 211 to rotate through the adapter block 233, and the rotating shaft 211 drives the push rod 213 to rotate away from the entrance 11 of the frame 10 until the push rod 213 is located outside the range of the entrance 11 of the carrier 200, thereby allowing the carrier 200 to enter and exit the accommodating space through the entrance 11.
[0049] When the telescopic end a2 of the telescopic member 231 retracts relative to the mounting end a1, the telescopic end a2 drives the rotating shaft 211 to rotate through the adapter block 233. The rotating shaft 211 drives the push rod 213 to rotate towards the carrier 200 located in the receiving space until the push rod 213 pushes each aging test board 300 on the carrier 200 to a preset position.
[0050] Further, the pre-pushing unit 20 further includes a detecting member disposed corresponding to the telescopic end a2 of the telescopic member 231. The detecting member is used to detect the position of the telescopic end a2 of the telescopic member 231. Thus, when the detecting member detects that the telescopic end a2 of the telescopic member 231 extends relative to the mounting end a1, it indicates that the push rod 213 is outside the range of the entrance 11 of the frame 10. At this time, the carrier 200 can enter and exit the receiving space of the frame 10 through the entrance 11. When the detecting member detects that the telescopic end a2 of the telescopic member 231 retracts relative to the mounting end a1, it indicates that the push rod 213 is within the range of the entrance 11 of the frame 10. At this time, the carrier 200 cannot enter and exit the receiving space of the frame 10 through the entrance 11. Optionally, the detecting member can be an optoelectronic sensor.
[0051] It should be noted that the driving assembly 23 is not limited to the above structure. Of course, other driving structures can also be used, as long as the rotating shaft 211 can be driven to rotate about its own axis, which is not limited herein. For example, the driving assembly 23 can also adopt a gear-rack driving structure. Specifically, the driving assembly 23 includes a gear, a rack and a linear driving member. The gear is coaxially mounted on the rotating shaft 211, so that the gear and the rotating shaft 211 can rotate synchronously. The rack is mounted on the driving end of the linear driving member and meshes with the gear, so that when the linear driving 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 about its own axis. Optionally, the linear driving member can be a cylinder.
[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0053] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
