Description

Technical Field

[0001] The utility model relates to the technical field of storage test equipment, in particular to an RDT test cart. Background Art

[0002] In the R&D and production of solid-state drives (SSDs), reliability and durability testing are key steps in ensuring product quality. Among them, RDT (Reliability Demonstration Testing) is an important testing method designed to comprehensively evaluate the performance stability and lifespan of SSDs under various conditions. The basic principle of RDT testing involves pre-burning a self-running program into the SSD. This program automatically starts after the SSD is placed in a temperature-controlled environment and powered on. It performs a series of operations on each storage block in the flash memory chip, including erasing, writing, saving, and reading, to simulate the working state of the SSD in actual use and generate detailed test data for analysis. After this series of operations is completed, the secondary card opening technology can be used to identify and isolate defective storage blocks (i.e., bad blocks), thereby ensuring the reliability of the final product.

[0003] It's worth noting that RDT testing is not only a mandatory test item in the SSD R&D process, but also uniquely convenient—it only requires powering on to start, with no additional data interface connections required. This simplifies the testing process and improves efficiency. However, conducting RDT testing in high-temperature environments places extremely high demands on the durability of the power supply and test boards, as high temperatures can accelerate the aging of electronic components, affecting the accuracy of test results and the lifespan of the test equipment.

[0004] Traditionally, cart systems used for RDT testing have relied primarily on gold finger and slot connector technology. This connection method performs well in standard SSD testing scenarios, but it is inadequate for the compression storage hard drive modules that have emerged in recent years. Compression storage hard drive modules utilize a board-to-board pin connection method, which is more compact and requires higher connection accuracy and stability. Because traditional RDT test cart systems do not fully consider the special characteristics of compression storage hard drive modules in their design, they encounter numerous challenges in actual applications, such as unstable connections and abnormal test data. As a result, RDT testing technology for compression storage hard drive modules is still in the exploratory stage and has yet to form a mature and reliable technical solution. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the present application provides an RDT test cart based on a magazine-type material box, which aims to improve test efficiency and accuracy and provide strong support for the quality control of SSD products.

[0007] In the above technical solution, slide rails are provided on both sides of the magazine-type material box, which match the slide grooves on the test slot.

[0008] In the above technical solution, the front end of the L-shaped electrode is equipped with a self-limiting rotating pressure rod for fixing the magazine-type material box.

[0009] The bottom of the cart body in the above technical solution is provided with four industrial high-temperature resistant nylon universal wheels.

[0011] The cart body described in the above technical solution is made of welded stainless steel pipes, the lower layer is not less than 80CM from the ground, and the uppermost layer is not more than 160CM.

[0013] In the above technical solution, a protective cover is provided between the cable and the aviation connector, and the protective cover is made of a transparent wear-resistant material.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0021] Given the above background, if Figure 1-4 As shown, the present invention provides an RDT test cart, including a cart body 1, a magazine-type material box 2, a test electrode 3, a cable 4 and an aviation connector 5, wherein:

[0022] The cart body 1 is divided into several layers by partitions 11, and a plurality of test slots 12 are arranged in each layer for installing the magazine-type material box 2; the cable 4 and the aviation connector 5 are gathered on the top layer of the cart body 1, and one end of the cable 4 is used to connect to the industrial power supply and switch of the step-type test box A.

[0023] The test electrode 3 includes an I-type electrode 31 and an L-type electrode 32. The other end of the cable 4 is connected to the I-type electrode 31 and the L-type electrode 32 through a terminal block; the L-type electrode 32 is arranged at both ends of the test slot 12, and the I-type electrode 31 is arranged in the middle position of the test slot 12; the L-type electrode 32 and the I-type electrode 31 are isolated by an insulating plate and installed in the test slot 12. Optionally, the electrodes all have a 180° reverse anti-foolproof design.

[0024] The 12V DC voltage is distributed to each test position on each layer through a high-temperature-resistant silicone flexible cable 4. It is then connected to electrodes 3 via terminal blocks. The L-shaped electrodes 32 on either side connect to the DC- (GND) terminal, while the I-shaped electrode 31 in the center connects to the DC+ (12V). Ample space is reserved between each test position and between each layer to facilitate air circulation within the test chamber and ensure precise temperature control.

[0025] In one possible implementation, the magazine-type material box 2 is provided with slide rails on both sides, which match the slide grooves on the test slot, so that the material box can be easily pulled out and inserted without disassembling other components, which is convenient for replacement and maintenance of test electrodes.

[0026] In one possible implementation, Figure 3 As shown, the front end of the L-shaped electrode 32 is equipped with a self-limiting rotating pressure rod 321 for fixing the magazine-type material box 2.

[0027] In one possible implementation, the cart body is welded with stainless steel pipes, the lower layer is not less than 80CM from the ground, and the uppermost layer is not more than 160CM, so that the operator can operate normally in a standing position, thereby improving the humanization of the operation.

[0028] Since the cart's load height is ≥80 cm and its center of gravity is high, in order to prevent it from tilting, a possible implementation method is as follows: Figure 4 As shown, counterweights 13 are provided at the four corners of the bottom layer of the cart body 1 for balancing the center of gravity.

[0029] In a possible implementation, four industrial high-temperature resistant nylon universal wheels 14 are provided at the bottom of the cart body 1 , which can withstand high temperatures and heavy loads and are used for mobile transportation.

[0030] In one possible implementation, the interior of the cart body is also equipped with a lighting system, including LED light strips or energy-saving bulbs, and corresponding switch controls, so that the status of the test electrodes and the magazine-type material box can be clearly observed even in a low-light environment to ensure the accuracy of the test operation.

[0031] In one possible implementation, a protective cover is provided between the cable and the aviation connector. The protective cover is made of a transparent wear-resistant material, which can not only protect the cable and the connector from external physical damage, but also facilitate the operator to observe the cable connection status, thereby ensuring the safety and reliability of the test process.

[0032] The beneficial effects of this application include:

[0033] ① The use of L-shaped and I-shaped electrodes not only integrates the dual functions of limiting and conducting, but also innovatively introduces a 180° reverse anti-foolproofing design, ensuring the accuracy of the electrodes during the connection process, effectively preventing equipment damage or test failure due to misoperation, and significantly improving the convenience and safety of operation.

[0034] ② To meet the needs of operators in different work scenarios, the operating interface and height are optimized, allowing operators to easily complete operations whether standing or sitting high. In addition, the application of anti-tilt design effectively solves the center of gravity shift problem that may occur during use of traditional equipment, further improving operational stability and comfort.

[0035] ③ On the premise of ensuring sufficient air circulation space, a three-dimensional loading design is adopted for everything from magazine-type material boxes to carts. This not only achieves high-density testing, but also greatly breaks through the bottleneck of traditional loading methods in physical space, bringing higher flexibility and efficiency to the testing process.

[0036] ④ By dividing the equipment into multiple independent modules, the impact of traditional large-volume handling and handling of materials on efficiency is effectively avoided. Modular applications not only simplify the equipment assembly and maintenance process, but also enable operators to respond to testing needs more quickly, further improving overall work efficiency and test accuracy.

[0037] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
