Description

Technical Field

[0001] This invention relates to the field of static storage technology, and more particularly to a testing device for solid-state drive (SSD) production. Background Technology

[0002] Solid-state drives (SSDs) are storage devices based on semiconductor memory chips, widely used in computers, servers, data centers, and consumer electronics. During the manufacturing process, to ensure that the performance, reliability, and stability of SSDs meet design requirements, they must undergo a series of rigorous tests. Testing equipment, as a key component of the production process, is primarily used to evaluate the read / write speeds, durability, power consumption, interface protocol compatibility, and other functional characteristics of SSDs.

[0003] One type of test is the data retention aging test, which is used to evaluate the charge retention capability of NAND flash memory. During the test, the hard drive is first filled with a specific data pattern at room temperature, then placed in an oven without power and left at a specific temperature for a set time. Finally, the hard drive is removed, and all written data is read sector by sector and compared before and after to complete the test.

[0004] Currently, most ovens used for data retention aging tests have a pull-out structure, where a tray similar to a drawer is pulled out, a hard drive is placed inside, and then it is inserted back into the oven. In this type of oven, the hot air flow path is basically fixed, which can easily lead to short-circuiting and uneven temperature inside the oven. Especially when not fully loaded, the hot air flow path tends to be more fixed, thus affecting the test results of hard drives in some locations. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art where a fixed hot air flow path may lead to uneven temperature inside the oven, and to propose a testing device for solid-state drive production.

[0006] The technical solution of the present invention: A testing device for solid-state drive (SSD) production includes an oven housing, a door rotatably disposed on the front side of the oven housing, and a heating mechanism disposed inside the oven housing that blows hot air from bottom to top; a rotating shaft is rotatably disposed inside the oven housing, and multiple testing mechanisms are arranged side by side on the rotating shaft. Each testing mechanism includes a support plate disposed on the rotating shaft, multiple ventilation holes disposed circumferentially on the support plate, and a truncated cone slidably disposed vertically on the support plate. The bottom of the truncated cone passes through the ventilation holes, and the SSD is placed on the top of the truncated cone. The truncated cone is a heat conductor, and a power component that drives the truncated cone to rise and fall is disposed inside the oven housing.

[0007] Preferably, the heating mechanism includes a heating device disposed on the inner wall of the bottom of the oven shell, a return air cavity disposed on the top of the oven shell, multiple return air pipes connecting the heating device and the return air cavity, and a fan disposed on the bottom of the oven shell. Multiple air outlet slots are provided on the top of the heating device shell, and the fan blows air upwards and blows out the heat generated by the heating device.

[0008] Preferably, an arc-shaped sealing plate a is provided on the inner wall of the oven door, and an arc-shaped sealing plate b is provided on the inner wall of the rear side of the oven shell. After the oven door is closed, the arc-shaped sealing plate a and the arc-shaped sealing plate b are spliced ​​together to form a cylindrical shape, and the inner wall of the cylinder contacts the support plate.

[0009] Preferably, the top of the frustum is provided with a hard disk placement slot and a material retrieval slot, with the material retrieval slot penetrating the hard disk placement slot and forming openings on both sides of the top of the frustum.

[0010] Preferably, a fixing plate is provided on the outer side of the frustum, and a guide hole is provided on the fixing plate. A guide rod is provided on the support plate, and the guide rod passes through the guide hole. The ventilation holes and frustum on the support plate are arranged in multiple rings, and the number of ventilation holes and frustums in each ring increases from the inside to the outside as the diameter increases.

[0011] Preferably, the power assembly includes a connecting frame mounted on a fixed plate, an arc-shaped guide rail mounted on top of the connecting frame, and a ring pressed against the top of the connecting frame. The bottom of the ring has an annular groove, and the arc-shaped guide rail is inserted into the annular groove. Multiple rings are provided, each with a different diameter. One ring corresponds to a truncated cone. A power unit is provided on the rear side of the oven shell to drive the multiple rings to rise and fall asynchronously.

[0012] Preferably, the power unit includes a telescopic device installed on the rear side wall of the oven shell, a crossbar installed at the telescopic end of the telescopic device, and multiple arc-shaped protrusions installed on the crossbar. Each of the multiple rings is provided with a U-shaped frame, the crossbar passes through the U-shaped frame, and the crossbar has multiple different positions, each of which pushes up the rings at different positions.

[0013] Preferably, a motor that drives the rotating shaft is installed on the bottom outer wall of the oven shell, and a control system and a control panel are installed on the front side of the oven shell, and the control panel and the control system are electrically connected.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: 1. By setting up a height-adjustable truncated cone, the distance between its conical surface and the ventilation hole changes as the cone rises and falls, thereby dynamically changing the resistance of hot air passing through and causing the hot air flow path to change continuously. This avoids the hot air forming a fixed flow path based on the minimum resistance and the phenomenon of short flow, effectively ensuring that the temperature is uniform in all positions in the oven, ensuring that each solid-state drive is subjected to aging test at a consistent test temperature, and improving the accuracy and reliability of the test results. 2. The support plate is driven by a motor to rotate slowly, so that the solid-state drives in different positions pass through different airflow areas in turn, eliminating local high temperature areas and low temperature dead zones in the enclosure, further improving the uniformity of temperature distribution, ensuring consistent test results for each hard drive, and is especially suitable for testing under non-full load conditions.

[0016] Example 1; as Figures 1-4As shown, the present invention proposes a testing device for solid-state drive (SSD) production, comprising an oven housing 1, a door 7 rotatably disposed on the front side of the oven housing 1, and a heating mechanism disposed inside the oven housing 1 that blows hot air from bottom to top; a rotating shaft 11 is rotatably disposed inside the oven housing 1, and a motor 10 is disposed on the bottom outer wall of the oven housing 1 to drive the rotating shaft 11 to rotate; multiple testing mechanisms are arranged side by side on the rotating shaft 11, and the testing mechanisms are located in the hot air flow path; each testing mechanism includes a support plate 12 disposed on the rotating shaft 11, multiple ventilation holes 13 disposed circumferentially on the support plate 12, and a truncated cone 14 slidably disposed vertically on the support plate 12; the bottom of the truncated cone 14 passes through the ventilation holes 13; and the SSD is placed on the top of the truncated cone 14. Specifically, the top of the truncated cone 14 is provided with a hard drive placement slot 15 and a material picking slot 16; the material picking slot 16 passes through the hard drive placement slot 15 and forms openings on both sides of the top of the truncated cone 14. Slot 15 is used to place solid-state drives (SSDs) to prevent them from slipping during the rotation of the support plate 12. The material handling slot 16 allows the operator to pass two fingers through and pinch the SSDs for easy loading and unloading. A fixing plate 17 is installed on the outer side of the frustum 14, with guide holes on the fixing plate 17. A guide rod 18 is installed on the support plate 12, passing through the guide holes. The ventilation holes 13 on the support plate 12 and the frustum 14 are arranged in multiple rings, with the number of ventilation holes 13 and frustums 14 increasing from the inside out as the diameter expands. The frustum 14 is a heat conductor. A power assembly is installed inside the oven shell 1 to drive the frustum 14 to rise and fall. The rising and falling of the frustum 14 changes the distance between its conical surface and the ventilation holes 13, altering the resistance to hot air flow and thus changing the hot air flow path. This prevents the hot air from forming a fixed flow path based on minimum resistance, ensuring uniform temperature inside the oven shell 1 and guaranteeing the testing effect of each SSD.

[0017] Furthermore, an arc-shaped sealing plate a8 is provided on the inner wall of the door 7, and an arc-shaped sealing plate b9 is provided on the inner wall of the rear side of the oven shell 1. After the door 7 is closed, the arc-shaped sealing plate a8 and the arc-shaped sealing plate b9 are spliced ​​together to form a cylindrical shape, and the inner wall of the cylinder is in contact with the support plate 12. Hot air flows from bottom to top in the cylinder and must pass through the ventilation hole 13.

[0018] Example 2; as Figures 1-2As shown, this invention proposes a testing device for solid-state drive production. Compared to Embodiment 1, this embodiment details the structure of the heating mechanism. Specifically, the heating mechanism includes a heating device 2 disposed on the inner wall of the bottom of the oven housing 1, a return air cavity 4 disposed on the top of the oven housing 1, multiple return air pipes 5 connecting the heating device 2 and the return air cavity 4, and a fan 3 disposed on the bottom of the oven housing 1. Multiple air outlet slots 6 are provided on the top of the heating device 2 housing. The fan 3 blows air upwards and blows out the heat generated by the heating device 2. The hot air then enters the heating device 2 through the return air cavity 4 and the return air pipes 5 to achieve internal circulation and reduce heat loss. In an optional embodiment, the heating device 2 includes a box disposed on the inner wall of the bottom of the oven housing 1 and an electric heating wire disposed inside the box. The electric heating wire generates high temperature when it operates, and the fan 3 blows the high temperature into the oven housing 1, with the hot air flowing from bottom to top.

[0019] Example 3; as Figures 3-5 As shown, the present invention proposes a testing device for solid-state drive production. Compared with Embodiment 1 or Embodiment 2, this embodiment details the structure of the power assembly. The power assembly includes a connecting frame 19 mounted on a fixed plate 17, an arc-shaped guide rail 20 mounted on the top of the connecting frame 19, and a ring 21 pressed against the top of the connecting frame 19. The bottom of the ring 21 is provided with an annular groove, and the arc-shaped guide rail 20 is inserted into the annular groove. Multiple rings 21 are provided, and each has a different diameter. One ring 21 corresponds to a truncated cone 14. A power unit is provided on the rear side of the oven housing 1 to drive multiple rings 21 to rise and fall asynchronously.

[0020] The power unit includes a telescopic device 25 mounted on the rear side wall of the oven shell 1, a crossbar 24 mounted on the telescopic end of the telescopic device 25, and multiple arc-shaped protrusions 23 mounted on the crossbar 24. U-shaped frames 22 are mounted on multiple rings 21, through which the crossbar 24 passes. The crossbar 24 has multiple different positions, each lifting the rings 21 at a different position. The rings 21 drive multiple truncated cones 14 at corresponding positions to move upwards, increasing the distance between the ventilation holes 13 and the truncated cones 14, thereby expanding the air outlet size and reducing the air pressure at that location. The flow resistance of the airflow is continuously adjusted at different positions to change the flow direction of the airflow. Combined with the slow rotation of the support plate 12, the temperature inside the oven shell 1 is evenly distributed, thereby ensuring the testing effect of each solid-state drive. In an optional embodiment, the telescopic device 25 is an electric push rod, and a round rod is provided between the telescopic end of the telescopic device 25 and the crossbar 24. The round rod passes through the rear wall of the oven shell 1 and the two are sealed. A mounting bracket is provided on the outer side of the rear wall of the oven shell 1 to fix the telescopic device 25.

[0021] Example 4; as Figures 1-4As shown, this invention proposes a testing device for solid-state drive production. Compared to Embodiment 3, this embodiment details the electrical control system. Specifically, a control system and a control panel 26 are installed on the front side of the oven housing 1. The control system is connected to the heating device 2, the motor 10, the fan 3, and the telescopic device 25. The control panel 26 is electrically connected to the control system and is used to perform various operations, such as temperature control, time control, airflow control, motor 10 speed control, and telescopic device 25 extension control. The control connection between the control system and the various electrical components is prior art and will not be described further here.

[0022] In summary, when using this invention, before the test begins, the solid-state drive (SSD) that has completed the full data writing is placed in the hard drive placement slot 15 corresponding to the frustum 14 on the support disk 12. The operator can take and place the SSD through the material retrieval slot 16. The hard drive placement slot 15 can prevent the SSD from slipping off during the rotation of the support disk 12. After placement, the door 7 is closed. The arc-shaped sealing plate a8 on the inner wall of the door 7 and the arc-shaped sealing plate b9 on the rear inner wall of the oven shell 1 are spliced ​​into a cylindrical shape, and the inner wall of the cylinder is in contact with the support disk 12, so that the hot air can only flow from bottom to top inside the cylinder and must pass through the ventilation hole 13. During testing, the control system activates the heating device 2 and the fan 3. The electric heating wire in the heating device 2 generates high temperatures, and the fan 3 blows air upwards, directing the heat through the air outlet 6 into the oven shell 1. The hot air flows from bottom to top, passing through the ventilation holes 13 on the support plate 12 in sequence, heating the solid-state drives on the frustum 14. After reaching the top, the hot air enters the return air chamber 4 and then returns to the heating device 2 through the return air pipe 5, achieving internal circulation and reducing heat loss. At the same time, the control system activates the motor 10, which drives the rotating shaft 11 to rotate. The rotating shaft 11 drives multiple support plates 12 to rotate slowly, causing each solid-state drive to pass through different airflow areas in turn. During the heating process, the control system controls the telescopic device 25 to move according to the temperature inside the oven. The telescopic end of the telescopic device 25 drives the crossbar 24 to move back and forth. The arc-shaped protrusions 23 at different positions on the crossbar 24 push up the U-shaped frame 22 at different positions, thereby driving the corresponding diameter ring 21 to slide upward along the arc-shaped guide rail 20 at the top of the connecting frame 19. The pushed-up ring 21 drives the corresponding truncated cone 14 to move upward along the guide rod 18, while the non-corresponding truncated cone 14 remains stationary. As a result, the distance between the conical surface of the truncated cone 14 and the ventilation hole 13 is dynamically adjusted, and the air outlet size and airflow resistance at each point change continuously. The hot air no longer flows short along the fixed path formed by the least resistance, but constantly changes its flow direction. Combined with the slow rotation of the support plate 12, the temperature inside the oven shell 1 is evenly distributed, ensuring that the test results of each solid-state drive are consistent. Once the set aging time and temperature are reached, the control system controls the heating device 2 to stop heating. After the temperature inside the oven shell 1 drops to a suitable range, the oven door 7 is opened, and each solid-state drive is taken out through the material chute 16. All written data is read sector by sector and compared before and after to complete the data retention aging test.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
