[0044] It should be noted that the controller control circuit can be realized by simple programming of those skilled in the art, which is common knowledge in the art, and only its use is not transformed, so the control mode and circuit connection are not described in detail.

[0045] The use process of the hard disk test machine provided by the utility model is as follows:

[0046] When using the device, during the installation operation of the switching power supply 3, on the outside of the machine body 1, first rotate the rotating plate 8 on the annular groove 7, and the rotating plate 8 generates a pulling force on the pull rope 11 during rotation, and the pull rope 11 in turn drives all the positioning pins 4 to move synchronously into the through groove 34. When the positioning pin 4 moves, the sliding block 10 connected thereto slides on the sliding groove 13, and in this process, the spring 14 is subjected to extrusion force. When the positioning pin 4 completely enters the through groove 34, the switching power supply 3 is directly inserted into the power supply insertion port 2. After the switching power supply 3 is stably inserted into the predetermined position, the positioning groove 5 on the switching power supply 3 corresponds to the position of the positioning pin 4. The operator releases the limiting of the rotating plate 8, and the spring 14 restores its elastic force under the cooperation of the sliding block 10, drives the positioning pin 4 to reset and clamps into the positioning groove 5 on the switching power supply 3. Through the multi-point clamping mode of the positioning pin 4 and the positioning groove 5 on the switching power supply 3, the multi-point fixing of the switching power supply 3 is realized. Even if a single point is loose, the remaining points can still ensure the installation stability of the switching power supply 3. When disassembling the switching power supply 3, the position adjustment of the plurality of positioning pins 4 can be realized by rotating the rotating plate 8, so that the disassembly of the switching power supply 3 can be quickly completed without tool assistance. During installation, the positioning pin 4 is designed with an inclined end, and the operator does not need to operate the rotating plate 8 in advance, but can directly insert the switching power supply 3 into the power supply insertion port 2. The switching power supply 3 is in contact with the inclined end of the positioning pin 4, which promotes the positioning pin 4 to automatically clamp into the positioning groove 5. In this way, while improving the installation stability of the switching power supply 3, the disassembly process is still very convenient, which provides convenience for the subsequent maintenance of the switching power supply 3.

[0047] In the process of carrying out the hard disk test operation, first, a plurality of hard disks to be tested are sequentially placed in and fixed in the plurality of hard disk test fixing cavities 17. The operator issues a test instruction through the operation panel 16, the central processing unit 26 of the control module 24 receives the instruction, and then sends a signal to the synchronous controller 23 of the synchronous test module 33, the synchronous controller 23 then simultaneously sends a test instruction to each test interface 18, each test interface 18 is correspondingly connected with the hard disk to be tested on the hard disk test fixing cavity 17, so as to achieve synchronous testing of multiple hard disks. In the testing process, the data collector 19 collects the test data of each hard disk and transmits it to the central processing unit 26 for analysis and processing. At the same time, the sensor 20 of the patrol detection module 32 monitors the temperature, vibration and other parameters of the hard disk near each hard disk mounting position in real time, and transmits the monitoring data to the central processing unit 26. The central processing unit 26 controls the servo motor 22 to start working, the driving end of the servo motor 22 drives the adjusting screw rod 29 to rotate, and through the screw transmission of the adjusting screw rod 29 and the adjusting block 27 and the sliding cooperation of the adjusting block 27 and the guide rail 21, the adjusting block 27 stably drives the electric mechanical arm 28 to move between each hard disk test fixing cavity 17, the movement of the electric mechanical arm 28 drives the camera 30 and the data reader 31 to move synchronously, wherein the camera 30 shoots the appearance and running state of the hard disk, and the data reader 31 reads the real-time data of the hard disk, which are also transmitted to the central processing unit 26. The central processing unit 26 comprehensively analyzes and judges the data from the synchronous test module 33 and the patrol detection module 32, and if an abnormal condition of the hard disk is detected, an alarm will be issued on the display screen 15 to prompt the operator. The data in the testing process and the final test result are stored in the storage unit 25 for subsequent query and analysis.
