Description

Technical Field

[0001] This application relates to the field of aging testing technology, and in particular to aging testing apparatus and aging testing methods. Background Technology

[0002] Electronic devices require aging tests to simulate real-world usage and expose potential faults. Aging test devices in related technologies use heating elements to generate hot air, which is then circulated into the device by a fan to homogenize the internal temperature and heat the electronic equipment.

[0003] However, poor gas flow can easily occur in certain areas of the aging test device, leading to uneven air temperature inside the device. This, in turn, causes uneven heating of electronic equipment and reduces the accuracy of the aging test. Summary of the Invention

[0004] This application provides an aging test apparatus and an aging test method to at least solve the problem of uneven heating in electronic devices in related technologies.

[0005] This application provides an aging test device, comprising: a housing, a tray, a heating element, a mixing element, and a first driving element. The housing contains a test chamber, the tray is located within the test chamber and is used to carry electronic equipment, the heating element is disposed on the housing and spaced apart from the tray, the mixing element is located within the test chamber and between the heating element and the tray, and the first driving element is throttle-connected to the mixing element and is used to drive the mixing element to reciprocate.

[0006] This application also provides an aging test method, comprising: placing an electronic device in a test chamber; heating the electronic device; disturbing the air in the test chamber; and performing an electrical test on the electronic device.

[0007] This application demonstrates that the heating element heats the electronic device via thermal convection. Due to the reciprocating motion of the mixing element, turbulence is generated in the air between the heating element and the electronic device. This enhances the air convection effect and accelerates the transfer of heat to the electronic device. On the other hand, it avoids localized airflow obstruction, allowing the air to mix and exchange heat fully. This improves the temperature uniformity of the air inside the test chamber. Therefore, it can solve the technical problem of uneven heating of electronic devices, achieving a more uniform temperature for electronic devices and improving the accuracy of aging tests.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0022] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] In related technologies, aging test devices generate hot air through heating elements and deliver circulating hot air into the aging test device through a fan, thereby homogenizing the internal temperature and heating the electronic equipment inside.

[0024] The circulating hot air will form a stable flow field in the aging test device, which can easily cause local areas to have poor air flow for a long time. This will cause the air temperature in that area to deviate from the average temperature. If this area happens to be located on the surface of the electronic device, it will cause uneven heating of the electronic device and reduce the test accuracy of the aging test.

[0025] The embodiments of this application provide an aging test device, and the aging test device is described in detail in conjunction with its structure and working principle.

[0026] Reference Figure 1 and Figure 2 The aging test apparatus provided in this application includes a housing 1, a tray 201, a heating element, a mixing element 401, and a first driving element 501. The housing 1 is provided with a test chamber 101. The tray 201 is located in the test chamber 101 and is used to carry electronic equipment 9. The heating element (not shown in the figure) is arranged on the housing 1 and spaced apart from the tray 201. The mixing element 401 is located in the test chamber 101 and is located between the heating element and the tray 201. The first driving element 501 is connected to the mixing element 401 and is used to drive the mixing element 401 to reciprocate.

[0027] It is understood that the electronic device 9 can be a product with a circuit structure, such as a mobile terminal, hard drive, or circuit board, and this application does not limit this. During the aging test, the electronic device 9 to be tested is placed on the tray 201, and the electronic device 9 is powered on to put it into working condition. The heating element heats the electronic device 9 through heat convection, thereby simulating a harsh usage environment in order to expose potential defects of the electronic device 9.

[0028] The reciprocating motion of the mixing element 401 generates turbulence in the air between the heating element and the electronic device 9. On the one hand, this enhances the air convection effect, accelerates the heat transfer to the electronic device 9, and promotes the temperature rise of the electronic device 9. On the other hand, the turbulence creates an unstable flow field in the test chamber 101, avoiding local airflow obstruction and allowing the air to mix and exchange heat fully, thereby improving the temperature uniformity of the air inside the test chamber 101.

[0029] Therefore, the aging test device can solve the technical problem of uneven heating of electronic device 9, and achieve the technical effect of more uniform temperature of electronic device 9 and improved test accuracy of aging test.

[0030] It is understood that in this application, the movement of the mixing element 401 can be moving, oscillating, or a combination of moving and oscillating. The transmission connection refers to various connection methods that can transmit energy and motion between the first driving element 501 and the mixing element 401. The first driving element 501 can transmit and connect the mixing element 401 in different ways to realize the reciprocating motion of the mixing element 401.

[0031] Optionally, in some embodiments, the aging test apparatus further includes an energy storage element 502 connected between the mixing element 401 and the first driving element 501. The energy storage element 502 is capable of alternately recovering and releasing energy to drive the mixing element 401 to reciprocate.

[0032] For ease of description, the reciprocating motion of the mixing element 401 is defined as including forward motion and reverse motion. The first driving element 501 provides energy to the energy storage element 502 through a transmission connection. The energy storage element 502 releases energy, driving the mixing element 401 to move forward. During the forward motion, the energy storage element 502 continuously recovers and stores the energy of the mixing element 401, causing the speed of the mixing element 401 to gradually decrease. When the mixing element 401 stops, the energy storage element 502 releases the stored energy, driving the mixing element 401 to move in reverse. During the reverse motion, the energy storage element 502 recovers and releases energy in the same way, causing the mixing element 401 to change from reverse motion to forward motion.

[0033] By adding an energy storage component 502, the first driving component 501 only needs to provide initial energy at the beginning of the movement of the mixing component 401, so that the mixing component 401 can maintain reciprocating motion for a certain period of time, thereby improving the energy utilization efficiency and helping to simplify the driving method of the first driving component 501.

[0034] For example, refer to Figure 1 , Figure 2 , Figure 3 In some embodiments, the energy storage component 502 includes a pendulum rod rotatably mounted on the housing 1. A first driving component 501 can push the pendulum rod to swing along its axis of rotation, which is horizontal. At this time, the pendulum rod performs a reciprocating pendulum motion, alternately converting the kinetic energy of the mixing component 401 into gravitational potential energy, and vice versa, thereby achieving the function of energy recovery and release.

[0035] Of course, in addition to storing energy through gravitational potential energy, the energy storage device 502 can also store energy through elastic potential energy, magnetic potential energy or other internal energy methods.

[0036] For example, in some embodiments not shown, a compression spring can be used as an energy storage element 502. Pairs of compression springs are located on both sides of the mixing element. When the mixing element 401 moves in the forward direction, it compresses one of the compression springs, converting the kinetic energy of the mixing element 401 into the elastic potential energy of the compression spring. After the mixing element 401 moves to the end position, the compression spring rebounds and pushes the mixing element 401 to move in the reverse direction. When the mixing element 401 moves in the reverse direction, it compresses the other compression spring, repeating the conversion process between kinetic energy and potential energy, thereby realizing reciprocating motion.

[0037] For example, in some other embodiments not shown, a piston can be used as an energy storage device 502. The piston has a piston rod and a piston cylinder. The piston cylinder has a gas chamber. The piston rod is inserted into the gas chamber. When the mixing member 401 moves in the forward direction, it actuates the piston rod on one side, compressing the gas in the gas chamber. The kinetic energy of the mixing member 401 is converted into the internal energy of the gas. After the mixing member 401 moves to the end position, the gas expands, pushing the piston rod to rebound, causing the mixing member 401 to move in the reverse direction. When the mixing member 401 moves in the reverse direction, it actuates the piston rod on the other side, repeating the conversion process between kinetic energy and internal energy, thereby realizing reciprocating motion.

[0038] Other feasible implementation methods for the energy storage device 502 can refer to existing related technologies. The energy storage device 502 can also be combined and utilized in a variety of ways to achieve energy storage and release, which will not be elaborated here.

[0039] Continue to refer to Figure 1 , Figure 2 , Figure 3 In some embodiments, the housing 1 is provided with a loading port that connects to the test chamber 101. The loading port is opposite to the tray 201 in a horizontal first direction. The tray 201 can extend or retract in the first direction through the loading port. The first driving member 501 is disposed on the tray 201 and protrudes from the tray 201 in a horizontal second direction. The energy storage member 502 is located on the movement path of the first driving member 501.

[0040] During aging tests, tray 201 extends from the loading port, and the electronic device 9 to be tested is placed on tray 201. It then follows tray 201 into test chamber 101. As tray 201 retracts, the first drive component 501 contacts the pendulum, causing it to swing and gain potential energy. As tray 201 continues to move, the pendulum disengages from the first drive component 501, converting the potential energy into kinetic energy, and begins to drive the mixing component 401 in reciprocating motion.

[0041] By utilizing the motion of the tray 201 to actuate the swing arm, the number of active components (or power sources) in the aging test device can be reduced, thereby lowering the implementation cost and the complexity of the control system. Furthermore, during the extension of the tray 201, the first driving component 501 can also act on the swing arm, causing the mixing component 401 to reciprocate, accelerating the dissipation of heat from the test chamber 101.

[0042] Furthermore, referring to Figure 4 The distance between the swing arms formed by the swing arm (which can be defined here as the distance from the pivot of the swing arm to the farthest end of the swing arm) is L1. In the vertical direction, the distance from the pivot to the first drive member 501 is H. In the first direction, when the tray 201 is retracted, the distance from the pivot to the first drive member 501 is L2. This ensures that the lever can smoothly disengage from the first drive unit 501 before the tray 201 moves to the end point.

[0043] In addition, in order for the first drive component 501 to collide with the swing arm during movement, the following settings are made: .

[0044] Optionally, the housing 1 is further provided with a first clearance groove 105 and a second clearance groove 106. The second clearance groove 106 is located in the second direction on the side of the first clearance groove 105 near the test chamber 101 and is connected to the test chamber 101. The second clearance groove 106 extends in the first direction and penetrates the housing 1 on the side where the loading port is located. The first driving member 501 extends into the second clearance groove 106. The first clearance groove 105 is connected to the outside in the second direction. The lower side of the first clearance groove 105 is connected to the second clearance groove 106. The swing arm is disposed in the first clearance groove 105, and the lower end of the swing arm extends into the second clearance groove 106, so that it can collide with the first driving member 501.

[0045] It should be noted that the movement of both the energy storage component 502 and the mixing component 401 will generate energy loss. Therefore, the movement amplitude of the mixing component 401 will gradually decrease until it stops completely. Since the mixing component 401 only moves for a short period of time after the first driving component 501 actuates and releases the pendulum, the aging test device with this design is preferably used for aging tests on electronic devices 9 that generate a large amount of heat or electronic devices 9 that need to move back and forth during the test. For the former, the mixing component 401 and the heating component only need to rapidly heat up the electronic device 9 in the early stage of the test, after which the electronic device 9 can maintain its temperature by its own heat generation. For the latter, the tray 201 needs to carry the electronic device 9 back and forth during the aging test, which can repeatedly actuate the pendulum to keep the mixing component 401 in reciprocating motion.

[0046] For example, the electronic device 9 under test is a hard disk drive (HDD). HDDs are data storage devices, including various types such as solid-state drives (SSDs), hard disk drives (HDDs), and hybrid hard disk drives (HHDs). HDDs generate a lot of heat when performing high-speed data reading and writing. In the initial stage of the aging test (that is, for a period of time after the tray 201 retracts), the heating element heats the hard disk, causing the hard disk temperature to quickly reach the target test temperature. The mixing element 401 reciprocates during this process, making the temperature rise of the hard disk more uniform. In the middle and late stages of the aging test, the hard disk maintains its test temperature by relying on the heat generated during operation, the heating element stops working, and the mixing element 401 is in a static state, without the need for turbulence.

[0047] Preferably, in some embodiments, the total time from movement to rest after the pendulum disengages from the first drive member 501 is defined as T1, and the estimated time from the start of the heating member to heating the electronic device 9 to a suitable temperature and then stopping is defined as T2. This ensures that the mixing element 401 can always play a mixing effect during the operation of the heating element. T1 and T2 can be obtained through experiments or simulation calculations, and can be adjusted by adjusting the weight of the swing arm and the parameters of the heating element (such as operating power).

[0048] In some embodiments, the aging test apparatus further includes a temperature sensor 301 located inside the test chamber 101 for detecting temperature in order to control the start / stop of the heating element and the power.

[0049] Optionally, in some embodiments, the aging test apparatus further includes a counterweight 503 disposed at the end of the pendulum rod. (Refer to...) Figure 3 The counterweight 503 can be a pendulum ball, the diameter of which is larger than the diameter of the pendulum rod, thereby effectively improving the energy storage capacity of the energy storage component 502. Obviously, referring to... Figure 4 When the pendulum is installed at the end, since the pendulum and the pendulum rod swing as a whole, the distance L1 of the pendulum arm is adjusted adaptively, taking into account the diameter of the pendulum.

[0050] By selecting a counterweight 503 of appropriate weight, the duration of the pendulum's reciprocating swing can be adjusted, thereby controlling the reciprocating motion time of the mixing component 401, thus achieving... The counterweight 503 can be made of metal and can be installed at the end of the pendulum rod by means of threaded connection, welding, etc. The pendulum ball can also be made of other materials and other connection methods, as long as it can effectively increase the weight, which will not be elaborated here.

[0051] Apart from Figure 1 , Figure 2 , Figure 3 In addition to the reciprocating motion of the mixing component 401 driven by the motion of the energy storage component 502 combined with the movement of the tray 201, the first driving component 501 can also use an active driving structure such as a drive motor, hydraulic cylinder, or pneumatic cylinder, provided that the requirements are met. The first driving component 501 can output linear motion or rotational motion, which is then converted into linear motion or rotational motion of the mixing component 401 through a transmission connection. This application does not impose any restrictions on this.

[0052] Optionally, in some embodiments, the heating element is located on the top and / or bottom wall of the test chamber 101, and the mixing element 401 is capable of reciprocating in a horizontal first direction and extending in a horizontal second direction. The mixing element 401 performs linear reciprocating motion, thereby ensuring that the speed of different parts of the mixing element 401 is consistent and improving the consistency of the turbulence effect in different areas; generally, the first direction is perpendicular to the second direction, and the direction of movement of the mixing element 401 is perpendicular to the extension direction, thereby maximizing the area traversed by the mixing element 401 and more fully turbulenting the air between the heating element and the electronic device 9.

[0053] For example, in some embodiments, the housing 1 is also provided with a plurality of receiving slots 102 that communicate with the test chamber 101. The receiving slots 102 extend in a first direction and are located on both sides of the test chamber 101 in a second direction. The two ends of the mixing component 401 are respectively inserted into the receiving slots 102.

[0054] On the one hand, the receiving groove 102 can play a guiding and positioning role, making the reciprocating motion of the mixing component 401 more accurate. On the other hand, the end of the mixing component 401 is inserted into the receiving groove 102, that is, the mixing component 401 penetrates the test chamber 101 in the second direction, thereby maximizing the range of motion of the mixing component 401 and improving the turbulence effect on the air in the test chamber 101.

[0055] Correspondingly, in some embodiments, the tray 201 is arranged vertically offset from the mixing element 401 located below the electronic device 9, so that the end of the mixing element 401 is inserted into the receiving groove 102.

[0056] Furthermore, in some embodiments, the aging test apparatus further includes a rolling element 402, which is disposed on the mixing member 401 and abuts against the wall of the receiving groove 102. The rolling element 402 can reduce the frictional resistance encountered by the mixing member 401 during reciprocating motion, making the motion smoother, and can also effectively reduce unnecessary energy loss, converting as much energy as possible into the kinetic energy of the air, and prolonging the duration of the reciprocating motion of the mixing member 401.

[0057] Specifically, refer to Figure 5 In some embodiments, the rolling element 402 includes a first roller, a second roller, and a third roller. The first roller and the second roller are located on opposite sides of the mixing element 401 in the vertical direction, and the third roller is located on the side of the mixing element 401 in the second direction. The first roller, the second roller, and the third roller are in contact with different surfaces of the receiving groove 102, thereby reducing frictional resistance in multiple directions.

[0058] In addition to rollers, the rolling element 402 can also use rolling structures commonly used in related technologies such as ball bearings and needle rollers, which will not be elaborated here.

[0059] It should be noted that by making the reciprocating motion direction of the mixing element 401 and the swing direction of the pendulum rod in the same direction (both along the first direction), it also helps to simplify the transmission connection between the mixing element 401 and the pendulum rod.

[0060] For example, refer to Figure 5 In some embodiments, the aging test apparatus further includes a meshing drive gear 504 and a drive rack 505. The drive gear 504 is mounted on the rocker arm, and the drive rack 505 is mounted on the mixing element 401 and extends in the first direction. The transmission method based on the drive gear 504 and drive rack 505 can easily convert the rotation of the rocker arm into linear motion of the mixing element 401. Furthermore, by adjusting parameters such as the diameter of the drive gear 504, the stroke range of the reciprocating motion of the mixing element 401 can be easily adjusted.

[0061] Specifically Figure 5 In the illustrated embodiment, the heating element is embedded in the top and bottom walls of the test chamber 101, and there are four mixing elements 401. The four mixing elements 401 are divided into two groups, one group is located on the upper side of the electronic device 9 in the vertical direction, and the other group is located on the lower side of the electronic device 9 in the vertical direction, thereby turbulenting the air on both sides.

[0062] In this configuration, two mixing elements 401 in the same group are located at the same height in the vertical direction and are spaced apart in the first direction. There are two drive racks 505, arranged opposite each other, meshing with the top and bottom of the drive gear 504 respectively. The two mixing elements 401 are connected to the two drive racks 505. When the drive gear 504 rotates, the drive racks 505 cause the two mixing elements 401 to move closer or further apart in the first direction. In addition to the turbulence generated by the reciprocating motion of the mixing elements 401, the opposing / backward motion of the two mixing elements 401 can also generate turbulence in opposite directions, thereby guiding the generated airflows to collide with each other and further enhancing the air turbulence effect.

[0063] Furthermore, in this case, to simplify the transmission connection structure, the drive rack 505 can be provided only on the mixing member 401 on one side (in... Figure 3 In the illustrated embodiment, the aging test device is only provided on the upper mixing element 401. The aging test device also includes a connecting rod 506, which connects the upper and lower mixing elements 401 to each other, so that the upper and lower mixing elements 401 reciprocate synchronously.

[0064] In other embodiments not shown, the number of mixing elements 401 can be further increased, and multiple mixing elements 401 at the same height can share a single drive rack 505, thereby simplifying the transmission connection structure. In this case, the movement of the multiple mixing elements 401 is in the same direction.

[0065] Besides the transmission method based on the drive gear 504 and drive rack 505, the conversion between rotation and movement can also be achieved through a linkage slider mechanism, a timing belt mechanism, etc. For example, in some embodiments, a slider is sleeved on the rocker arm, and the slider and the mixing member 401 are hinged together. The slider can move along the rocker arm, thereby converting the swing of the rocker arm into the movement of the mixing member 401 in the first direction.

[0066] Other feasible transmission methods can be found in relevant technologies, and will not be elaborated here.

[0067] Optionally, in some embodiments, the heating element is embedded in the top and bottom walls of the test chamber 101. Heat is first conducted between the heating element and the housing 1, and then the electronic device 9 is heated by convection heat transfer between the housing 1 and the electronic device 9. By utilizing the housing 1 for heat conduction, the phenomenon of excessively high local temperatures caused by the heating element being directly exposed inside the test chamber 101 can be avoided, thus improving the temperature uniformity of the air inside the test chamber 101.

[0068] The heating element can be a PTC heating element. The PTC heating element generates heat through resistance heating. When current flows through the PTC heating element, heat is generated rapidly to quickly create a stable high-temperature operating environment. After the PTC heating element reaches its set temperature, the resistance of the PTC heating element will increase significantly, thereby reducing the risk of overheating and ensuring the reliability of aging tests.

[0069] In some embodiments, the top and bottom walls are provided with heat dissipation holes 104 that communicate with the test chamber 101. The test chamber 101 can exchange with the outside air through the heat dissipation holes 104, which helps the test chamber 101 to dissipate heat when it is overheated, thereby maintaining the temperature stability of the test chamber 101 and the electronic device 9.

[0070] Optionally, in some embodiments, the aging test device further includes an impeller 403, which is rotatably mounted on the mixing member 401. The axis of rotation of the impeller 403 forms an angle with the direction of movement of the mixing member 401. During the reciprocating motion of the mixing member 401, the air can exert a force on the impeller 403, causing the impeller 403 to rotate. The rotating impeller 403 then reacts with the air, improving the air mixing effect.

[0071] Specifically, the impeller 403 can have multiple blades, which are arranged at equal intervals along the circumference of the impeller 403. Each blade has a first surface and a second surface, and the first and second surfaces have different surface shapes, resulting in different aerodynamic characteristics. When air acts on the impeller 403, the different blades experience different pressures. The pressure from the multiple blades forms a torque that drives the impeller 403 to rotate around its own axis. The specific design of the impeller 403 can be referenced in the design of cup anemometers in related technologies, and will not be elaborated upon here.

[0072] For example, refer to Figure 6 The aging test device also includes a connecting shaft 404, which is vertically mounted on the mixing element 401 and can rotate around its own axis. Multiple impellers 403 are respectively fixed at both ends of the connecting shaft 404, thereby enhancing the turbulence effect of the air between the mixing element 401 and the heating element, as well as the air between the mixing element 401 and the electronic device 9.

[0073] In some embodiments not shown, the connecting shaft 404 may also be fixedly mounted on the mixing member 401, and the impeller 403 may be rotatably mounted on the connecting shaft 404 and limited by a snap ring. This application does not impose any restrictions on this.

[0074] Optionally, in some embodiments, reference is made to Figure 1 The aging test device also includes a limiting member 202. The tray 201 has a mounting slot for accommodating and supporting the electronic device 9. The limiting member 202 is set on the tray 201 and can close or open the entrance of the mounting slot, thereby limiting the electronic device 9.

[0075] Exemplarily, in some embodiments, the inlet of the mounting slot faces upward, and the electronic device 9 is placed in the mounting slot with its thickness direction perpendicular to the vertical direction. The depth of the mounting slot matches the thickness of the electronic device 9. When the electronic device 9 is placed in the mounting slot, the top surface of the electronic device 9 is flush with the top surface of the tray 201 and exposed at the inlet of the mounting slot. A limiting member 202 is rotatably disposed on the top surface of the tray 201. The limiting member 202 rotates to the inlet and abuts against the top surface of the electronic device 9 to press the edge of the electronic device 9, so that the electronic device 9 is stably positioned within the tray 201.

[0076] The limiting member 202 only presses down on the edge of the electronic device 9, thereby obstructing the top surface of the electronic device 9 as little as possible, reducing the obstruction to the heat exchange of the electronic device 9, which helps the convection heat exchange between the air and the top surface in the test chamber 101 and reduces the temperature unevenness of the electronic device 9.

[0077] Optionally, the bottom of the tray 201 may also have perforations to expose the bottom surface of the electronic device 9, which helps the air in the test chamber 101 and the bottom surface to convect and exchange heat, and reduces the temperature unevenness of the electronic device 9.

[0078] Optionally, in some embodiments, the aging test apparatus further includes a second drive member 601, which is connected to the tray 201 and is used to drive the tray 201 to move in a first direction.

[0079] Exemplarily, in some embodiments, reference is made to Figure 2 and Figure 7 The second driving component 601 is a rotary motor. The aging test device also includes a support base 602 and a lead screw 603. The support base 602 is located at the bottom of the drive chamber 103. The lead screw 603 is mounted on the support base 602 and extends in the first direction. The bottom of the tray 201 is threadedly connected to the lead screw 603. The second driving component 601 can drive the lead screw 603 to rotate, thereby moving the tray 201 in the first direction.

[0080] Furthermore, the aging test device also includes a guide rod 605, the end of which is disposed on the housing 1. The guide rod 605 extends in a first direction, and the tray 201 is disposed on the guide rod 605, thereby moving accurately in the first direction under the guidance of the guide rod 605.

[0081] In addition to the rotary motor, the second drive unit 601 can also automatically drive the pallet 201 through linear motors, cylinders, hydraulic cylinders, etc., which will not be elaborated here.

[0082] Optionally, refer to Figure 8 In some embodiments, a drive chamber 103 is further provided inside the housing 1, and the second drive component 601 is located inside the drive chamber 103. The aging test device also includes a heat insulation plate 701, which separates the drive chamber 103 and the test chamber 101. The heat insulation plate 701 can reduce the temperature rise of the drive chamber 103 during the aging test and improve the service life of the second drive component 601. The material of the heat insulation plate 701 can be commonly used heat insulation materials in related technologies, such as fiberglass, ceramics, etc., which will not be described in detail here.

[0083] Optionally, refer to Figure 8 In some embodiments, the drive chamber 103 is located on the side of the test chamber 101 away from the feed port in the first direction. One end of the lead screw 603 extends into the drive chamber 103 through the heat insulation plate 701 and is connected to the output shaft of the second drive member 601 via a coupling, thereby realizing the power output of the second drive member 601. In addition to the coupling, the lead screw 603 can also be connected to the output shaft by other means, such as using a synchronous belt and pulley, or gears, etc., which will not be elaborated here.

[0084] Furthermore, in some embodiments, the aging test apparatus further includes a test connector 801, which is located inside the test chamber 101 and is located at the end of the test chamber 101 away from the feed port in a first direction.

[0085] The test connector 801 is used to perform power-on testing on the electronic device 9. By setting the test connector 801 in a position opposite to the loading port, the electronic device 9 can contact the test connector 801 when the tray 201 retracts to the end of its stroke in the first direction, and the electronic device 9 separates from the test connector 801 when the tray 201 extends in the first direction. This integrates the loading and unloading action of the tray 201 and the insertion and removal action of the electronic device 9, making the structure of the aging test device simpler and more convenient to use.

[0086] In addition, in some embodiments, the tray 201 is provided with a wiring hole that connects to the mounting slot at one end near the test connector 801. After the electronic device 9 is placed in the mounting slot, the interface of the electronic device 9 is exposed to the wiring hole so that the test connector 801 and the interface can be connected.

[0087] In some embodiments, the test connector 801 is communicatively connected to an external testing machine via a cable 802. The testing machine is equipped with a control system for controlling the aging test process. The testing machine can connect to multiple aging test devices simultaneously, thereby achieving batch and unified control of aging tests. For example, multiple aging test devices can be arrayed in a test cabinet, and the testing machine is also housed in the test cabinet, forming an integrated aging test system.

[0088] It is understood that the test machine can be any computer device with data processing capabilities, such as a computer, server, mobile terminal, data center, etc. The test connector 801 can be directly connected to the test machine via cable 802, or it can be connected to an intermediate device via cable 802, and then the intermediate device and the test machine in the cloud can interact with each other. This application does not limit this.

[0089] Alternatively, in some embodiments not shown, the aging test apparatus integrates a control board, which is communicatively connected to the test connector 801 via cable 802 to control the input and output of the test connector 801. In this case, the control board is located inside the drive chamber 103, and the cable 802 passes through the heat insulation plate 701 to connect to the control board, thereby preventing thermal failure of the control board and improving the operational reliability of the aging test apparatus.

[0090] This application also provides an aging test method, for reference. Figure 9 The aging test method provided in the embodiments of this application includes the following steps:

[0091] Step S110: Electronic device 9 is placed in test chamber 101.

[0092] It is understood that the test chamber 101 is used to carry out aging tests, and the electronic device 9 can be a product with a circuit structure such as a mobile terminal, hard disk, or circuit board. This application does not limit this.

[0093] Step S120: Heat the electronic device 9.

[0094] It is understandable that air can be heated by heating elements (such as resistance wires or resistance sheets), thereby heating the electronic device 9 through convection heat transfer, raising the temperature of the electronic device 9 to the temperature required for aging tests.

[0095] Alternatively, the air temperature inside the test chamber 101 can be increased by continuously supplying hot air into the test chamber 101 through an air inlet and an air outlet connected to the test chamber 101, thereby heating the electronic device 9 through convection heat transfer.

[0096] In some embodiments, the electronic device 9 is capable of self-heating, so step S120 ends after the electronic device 9 is heated to the temperature required for the aging test.

[0097] Step S130: Disturb the air inside test chamber 101.

[0098] It is understood that the reciprocating motion of the mixing element 401 can achieve a disturbance effect, making the flow field in the test chamber 101 unstable and avoiding prolonged periods of poor gas flow in local areas. Optionally, in some embodiments, step S130 begins before step S120 and ends after step S120, thereby ensuring that turbulence is always present during the air heating process.

[0099] Step S140: Perform a power-on test on electronic device 9.

[0100] It is understandable that by powering on the electronic device 9, it is made to run continuously in a simulated working state in order to expose the potential defects of the electronic device 9 in conjunction with the external high temperature environment.

[0101] According to the aging test method provided in this application, the air in the test chamber 101 is disturbed, thereby generating turbulence, avoiding poor gas flow in local areas of the test chamber 101, ensuring that the gas in the test chamber 101 is fully mixed, making the gas temperature more uniform, which helps to heat the electronic device 9 more evenly and improve the test effect of the aging test.

[0102] The aging test method can be implemented using the aging test apparatus provided in this application, or it can be implemented using other aging test apparatus with turbulence capability, and this application does not limit it.

[0103] An aging test method according to another embodiment of this application includes the following steps:

[0104] Step S210: Electronic device 9 is placed in test chamber 101.

[0105] Specifically, step S210 further includes:

[0106] Step S211: Tray 201 extends out of test chamber 101.

[0107] The tray 201 is used to carry the electronic device 9 to be tested. The tray 201 extends out of the test chamber 101 for loading.

[0108] Step S212: Electronic device 9 is placed on tray 201.

[0109] Step S213: The tray 201 retracts into the test chamber 101, and the tray 201 actuates the energy storage component 502, so that the energy storage component 502 obtains energy.

[0110] The kinetic energy of the tray 201 can be converted into the elastic potential energy (e.g., the energy storage component 502 is a spring), gravitational potential energy (e.g., the energy storage component 502 is a rocker arm), or internal energy (e.g., the energy storage component 502 is a piston) of the energy storage component 502.

[0111] Step S220: Heat the electronic device 9.

[0112] Specifically, step S220 further includes:

[0113] Step S221: Activate the heating element to heat the upper and lower surfaces of the electronic device 9 simultaneously.

[0114] Step S222: When the temperature sensor 301 detects that the temperature has risen to the specified temperature, it controls the heating element to cut off the power and the heating element stops heating.

[0115] Step S230: Disturb the air inside test chamber 101.

[0116] Specifically, step S230 further includes:

[0117] Step S231: The energy storage unit 502 alternately recovers and releases energy to drive the mixing unit 401 located inside the test chamber 101 to reciprocate, disturbing the air.

[0118] By utilizing the kinetic energy of the tray 201 to drive the reciprocating motion of the mixing component 401, the reciprocating motion of the mixing component 401 and the retraction of the tray 201 can be coupled together, which helps to reduce the number of active components required for the aging test method and reduce implementation costs.

[0119] It is understandable that the movement of both the energy storage component 502 and the mixing component 401 will generate energy loss. Therefore, the movement amplitude of the mixing component 401 will gradually decrease until it stops completely. Optionally, the total time for the mixing component 401 to move from motion to rest is defined as T1, and the duration of step S220 (that is, the duration from step S221 to step S222) is defined as T2. This ensures that the mixing element 401 can always play a mixing effect during the air heating process.

[0120] Step S240: Perform a power-on test on electronic device 9.

[0121] The details of step S240 can be found in step S140, and will not be repeated here.

[0122] The following describes the working process of some embodiments of the aging test apparatus. Based on the following content, it will help to better understand the aging test apparatus and aging test method provided in this application.

[0123] Material feeding: When aging tests are required on electronic device 9, the aging test device receives instructions from the test machine to rotate the second drive component 601, drive the tray 201 out of the test chamber 101, place the electronic device 9 into the tray 201, and rotate the limiting component 202 to limit the electronic device 9.

[0124] Next, the second drive unit 601 rotates in the opposite direction, moving the tray 201 into the test chamber 101 and allowing the interface of the electronic device 9 to be inserted into the test connector 801. During the process of the tray 201 entering the test chamber 101, the first drive unit 501 passes through the energy storage unit 502 (pendulum) and the counterweight 503 (pendulum ball). After the tray 201 is in place, the first drive unit 501 disengages from the pendulum ball. The pendulum ball drives the pendulum to swing back and forth, which in turn drives the drive gear 504 to rotate back and forth. The reciprocating rotation of the drive gear 504 drives the two drive racks 505 to slide back and forth in opposite directions, thereby causing the mixing unit 401 to alternately move closer and further away from each other.

[0125] Aging Test: The aging test device receives instructions from the testing machine and activates the heating element to simultaneously heat the upper and lower surfaces of the electronic device 9. During the heating process, the mixing element 401 causes the surrounding heated air to flow alternately to both sides and towards the center. The reciprocating motion of the mixing element 401 generates an unstable flow field between the heating element and the electronic device 9, promoting air mixing. During the reciprocating motion of the mixing element 401, the airflow also drives the impeller 403 to rotate. The impeller 403 contacts and turbulents the nearby air, further accelerating the mixing of the airflow. This results in a uniform temperature inside the test chamber 101, improving the accuracy of the aging test.

[0126] When the temperature sensor 301 detects that the temperature has risen to the specified temperature, the aging test device receives an instruction from the test machine to control the heating element to cut off the power and stop heating. At this time, the mixing element 401 continues to reciprocate and stops completely after a period of time when the heating element stops heating.

[0127] Material feeding: After the test is completed, the second drive component 601 rotates, driving the tray 201 to move outside the test chamber 101. The first drive component 501 passes through the swing rod and the swing ball again. At this time, the mixing component 401 reciprocates again. The mixing component 401, together with the impeller 403, makes the hot air in the test chamber 101 quickly dissipate through the heat dissipation hole 104.

[0128] In summary, the aging test device embodiment of this application uses the second driving component 601 to drive the tray 201 to move the electronic device 9, so that the test connector 801 is automatically inserted into the interface of the electronic device 9, thereby improving the automation level of the electronic device 9 connecting to the test machine; the reciprocating sliding of the mixing component 401 mixes the air in the test chamber 101, and in conjunction with the impeller 403, makes the temperature inside the test chamber 101 uniform, thereby improving the accuracy of the aging test; the movement of the tray 201 causes the pendulum ball and pendulum rod to drive the drive gear 504 to swing back and forth, thereby causing the mixing component 401 to move back and forth, without the need for an additional drive source, thus saving energy.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application.
