Description

Technical Field

[0001] The utility model relates to the technical field of hard disk testing, in particular to a one-stop hard disk testing device capable of controlling high and low temperatures. Background Art

[0002] Hard drive testing generally refers to a series of performance and health assessments of the hard drive to ensure it is functioning properly and to predict possible future problems. Hard drive testing can be divided into several types, including performance testing, health testing, error scanning, etc.

[0003] One-stop hard drive testing refers to the use of specialized hardware and software tools to conduct comprehensive testing of hard drives on an integrated platform. This testing method can reduce the complexity of manual operations, improve testing efficiency, and provide more accurate test results; according to the latest search results, there is a one-stop fully automated testing machine for solid-state drives, which includes a server terminal, a client test terminal, a network system, and a test chamber. This test machine can control multiple client test terminals through a network system to achieve one-stop fully automated testing of solid-state drives. Test items include but are not limited to appearance inspection, weight measurement, read and write performance testing, stability testing, seismic performance testing, and other indicators. The test results can be viewed through an industrial touch screen, and test reports can be automatically generated.

[0004] For mobile hard disks, there are professional third-party testing agencies that provide reliability testing services, which usually include comprehensive testing and analysis of product composition analysis, testing items and standards, etc. Testing items may include appearance inspection, weight measurement, read and write performance testing, stability testing, seismic performance testing, etc.

[0005] In summary, hard drive testing is an important step to ensure hard drive performance and health, and one-stop hard drive testing technology provides a more convenient and efficient testing solution.

[0033] On this basis, the equipment body 10 is also integrated with a temperature control chamber 50 and an air conditioning chamber 60. The temperature control chamber 50 is provided with an air inlet body 51 connected to one side of the test chamber 20 and an air outlet body 52 connected to the other side of the test chamber 20. A blowing device 53 and an evaporator 54 are also provided in the test chamber 20.

[0035] The evaporator 54, the air compressor 61, the four-way reversing valve 62, and the condenser 63 are connected to form a refrigeration cycle system or a heating cycle system. The flow direction of the refrigerant between the condenser 63 and the evaporator 54 is switched by the reversal of the four-way reversing valve 62, so that the functions of the condenser 63 and the evaporator 54 can be switched with each other, thereby achieving the purpose of controlling the temperature in the temperature control chamber 50; the temperature control chamber 50 is provided with a blowing device 53 and an air inlet body 51 and an air outlet body 52 structure, so that the temperature control chamber 50, the air inlet body 51, the test chamber 20 and the air outlet The main body 52 forms a directional circulating fluid that can flow through the evaporator 54 through the blowing device 53, which can control the heating or cooling of the test chamber 20, so as to achieve the performance test of the hard disk in a high temperature or low temperature environment; by coordinating multiple chambers on the equipment main body 10, the structural design is ingenious, which is equivalent to changing the heating system of the traditional aging test machine to a system similar to air conditioning, thereby adjusting the hard disk test environment in the test chamber 20, so that the hard disk can be subjected to aging tests in a high temperature environment, and performance tests in a low temperature environment.
