The scheme builds a network system based on server terminal and customer test terminal, so that one server can control multiple customer test terminals at the same time. The software of different test projects is implanted in each customer test terminal, and the PWM temperature control system is set uniformly combined with RDT and BIT test environment, and all test operations are controlled by the server. In this way, only one workstation and one post are needed, and one -key test is realized by means of an industrial touch screen, so that the test task originally undertaken by five traditional manual workstations can be completed in one station, and the test efficiency is improved significantly.

Detailed Implementation

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-6 In this embodiment of the present invention, a one-stop hard drive testing device for easy replacement and repair of test boards includes a testing machine body 10. A testing chamber 11 is located at the front of the testing machine body 10, and a control chamber 12 is located at the rear of the testing machine body 10. A central control module 13, a switch 14, a power module 15, and multiple servers 16 are located within the control chamber 12. A high-temperature circulation system 17 is located within the testing chamber 11. The switch 14, servers 16, and the high-temperature circulation system are all electrically connected to the central control module 13. The power module 15 provides power to the testing machine body 10. A partition 20 is provided between the testing chamber 11 and the control chamber 12. Multiple hard drive test boards 30 are detachably mounted on the partition 20, and the multiple hard drive test boards 30 are sequentially connected to the multiple servers 16. A connection is provided on the partition 20. Multiple fixing slots 21 are provided for multiple hard disk test boards 30. A connection window 22 communicating with the control compartment 12 is provided in the fixing slot 21. Multiple equally spaced abutment blocks 23 are formed on the left and right sides of the opening edge of the fixing slot 21. Multiple equally spaced positioning pieces 24 are formed on both sides of the hard disk test board 30. The hard disk test board 30 extends into the fixing slot 21 by the positioning pieces 24 and the abutment blocks 23 being misaligned. The hard disk test board 30 moves downward so that the positioning pieces 24 and the abutment blocks 23 abut against each other, thus restricting the hard disk test board 30 in the fixing slot 21. An abutment strip 25 for abutting the hard disk test board 30 is also formed at the lower edge of the opening edge of the fixing slot 21. A fixing plug strip 26 can be embedded in the upper end of the fixing slot 21 to restrict the hard disk test board 30 from moving upward.

[0027] In the above technical solution, when installing the hard disk test board 30, the positioning pieces 24 on both sides of the hard disk test board 30 are first misaligned with the abutment blocks 23 on the left and right edges of the opening of the fixing groove 21 of the partition 20. At this time, the hard disk test board 30 can be smoothly inserted into the fixing groove 21. After the hard disk test board 30 is moved to the appropriate position, it is moved downward so that the positioning pieces 24 and the abutment blocks 23 abut against each other. Since the abutment blocks 23 are evenly distributed, the positioning pieces 24 can accurately fit into the gaps between the abutment blocks 23, thereby restricting the position of the hard disk test board 30 in the horizontal direction. At the same time, the abutment strip 25 on the lower edge of the opening of the fixing groove 21 can prevent the hard disk test board 30 from continuing to move downward in the vertical direction, thus achieving the initial fixation of the hard disk test board 30.

[0028] Next, the fixing strip 26 is installed. The fixing strip 26 can be embedded into the upper end of the fixing groove 21 through interference fit or snap-fit ​​connection. If interference fit is used, the size of the fixing strip 26 will be slightly larger than the opening size of the upper end of the fixing groove 21. During installation, a certain amount of external force needs to be applied to press the fixing strip 26 into the fixing groove 21. The tight friction between the strip and the fixing groove 21 can effectively prevent it from loosening, thereby preventing the hard disk test board 30 from moving upward. If snap-fit ​​connection is used, the fixing strip 26 will have a specific snap-fit ​​structure, and a corresponding slot is set at the upper end of the fixing groove 21. During installation, align the fixing strip 26 with the slot and press gently. The snap-fit ​​will then lock into the slot, preventing the hard disk test board 30 from moving upward, thus completing the installation and fixation of the hard disk test board 30 from all directions. At this time, the hard disk test board 30 is connected to the server 16 in the control compartment 12 through the connection window 22. Under the unified control of the central control module 13, and in conjunction with components such as the high temperature circulation system 17 in the test compartment 11, it can perform various test tasks such as RDT test and BIT test on the hard disk.

[0029] When the hard drive test board 30 needs repair or replacement, first operate on the retaining strip 26. If it is an interference fit, carefully apply force to pull the retaining strip 26 out of the retaining groove 21; if it is a snap-fit ​​connection, press the unlocking mechanism at the snap to separate the snap from the groove and remove the retaining strip 26. Next, lift the hard drive test board 30 upwards to disengage the positioning piece 24 from the stop block 23, and then pull the hard drive test board 30 out of the retaining groove 21 to complete the disassembly. Afterwards, the new hard drive test board 30 can be reinstalled into the retaining groove 21 according to the above installation steps to restore the normal operation of the test equipment.

[0030] This design, compared to traditional screw connections, utilizes a structure with a positioning plate 24 and a stop block 23, a stop bar 25, and a fixing plug 26, greatly simplifying the disassembly and installation process of the hard disk test board 30. In case of test board malfunction, replacement or repair can be completed quickly, significantly saving maintenance time, improving equipment availability, reducing production downtime due to equipment maintenance, and ensuring smooth production flow.

[0031] The convenient test board replacement method significantly reduces the manpower required for maintenance. Workers no longer need to spend considerable time and effort on tedious screw removal and installation; a single person can efficiently complete the test board maintenance, reducing labor costs and improving manpower utilization. Furthermore, the ability to quickly replace test boards with compatible ones for different interface hard drive models significantly enhances the equipment's versatility.

[0032] Please see Figures 3-5 Based on the above technical solution, it is further proposed that the longitudinal dimensions of the stop block 23, the longitudinal dimensions of the positioning piece 24, the spacing between adjacent stop blocks 23, and the spacing between adjacent positioning pieces 24 are all equal. This ensures that during the installation of the hard disk test board 30, the positioning piece 24 can accurately and conveniently match the stop block 23, greatly improving the efficiency and accuracy of installation. During maintenance, when the test board needs to be disassembled or replaced, the consistency of the dimensions of each component allows staff to quickly separate the positioning piece 24 from the stop block 23, further optimizing the maintenance process.

[0033] Please see Figures 4-5 Based on the above technical solution, a further proposal is made to form a contour edge 27 on the inner side of the fixing slot 21 through the opening of the connecting window 22. The contour edge 27 forms a gap with the abutment block 23 and the abutment strip 25 respectively to just accommodate the hard disk test board 30. The precise matching gap design ensures that the hard disk test board 30 is stable after installation, and the accuracy of the test results will not be affected by shaking or displacement during the test, thus improving the stability of the equipment operation. The upper edge of the contour edge 27 is set to abut against the fixing plug strip 26 and the hard disk test board 30 at the same time. This not only strengthens the fixing effect of the hard disk test board 30 and prevents it from loosening in the vertical direction, but also makes the connection between the fixing plug strip 26, the hard disk test board 30 and the fixing slot 21 tighter and more stable. This further optimizes the equipment structure and reduces the potential for failure caused by improper fit between components. Whether in daily use or equipment maintenance, it can effectively ensure the efficient operation of the equipment and lay a solid foundation for the smooth development of large-scale hard disk testing.

[0034] Please see Figures 3-5Based on the above technical solution, it is further proposed that multiple connection windows 22 are arranged in an array on the partition 20 to facilitate the large-scale integration of the hard disk test board 30. In addition, an indicator light 28 is set at the lower part of each connection window 22 on the partition 20, which can intuitively reflect the working status of the corresponding hard disk test board 30. The staff can quickly judge whether the test board is running normally by the on / off state or color change of the indicator light 28, which greatly improves the efficiency of troubleshooting.

[0035] Please see Figure 5 Based on the above technical solution, it is further proposed that the front side of the hard disk test board 30 is provided with multiple hard disk connection ports 31, and the rear side of the hard disk test board 30 is provided with an adapter port 32 for connecting to the server 16.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
