An Intelligent Test System for Refrigerator Durability Test

Abstract

The invention, which relates to the technical field of test equipment, discloses an intelligent test system for durability test of a refrigerator. The intelligent test system is composed of a controlmodule, a test module and an uninterruptible power supply module. The control module is used for carrying out real-time control of the working condition of the test module and setting, adjusting, andfeeding back working parameters of the test module based on needs. The test module is used for carrying out testing on the durability of the refrigerator baesd on parameters set by the control module.The uninterruptible power supply module consists of a circuit control module, a commercial power module, and a storage battery module and is used for providing uninterrupted power supply for the control module and the test module. According to the invention, the test process of the refrigerator is controlled in real time and the performance of the refrigerator is tested continuously; matching ofrefrigerators with different types is realized quickly; a matching problem of the opening / closing track of the refrigerator door is solved; the intelligent test system is installed conveniently and quickly; the upper door and the lower door of the refrigerator can be opened or closed automatically and repeatedly; the equipment safety stability coefficient is high and the fault rate is low; and thestructure is simple and the cost is low.

Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to an intelligent test system for refrigerator durability tests. Background technique [0002] At present, automation and intelligent systems are used more and more frequently in industrial production. How to relieve workers from heavy work has become the primary task of improving productivity. In the test of the refrigerator door hinge, faced with the tedious work of repeatedly opening and closing the door. At present, the action of repeatedly opening and closing the door is mainly done manually, which is cumbersome and boring work, and the test efficiency is low. [0003] The test module structure of the existing refrigerators cannot be well matched with various types of refrigerators, and its structural stability is not good at the same time. There are many kinds of failures, such as the suction cup falling, the mechanical arm is worn, the opening and closing force is to...

Problems solved by technology

At present, the action of repeatedly opening and closing the door is mainly done manually, the work is tedious and boring, and the test efficiency is low

[0003] The test module structure of the existing refrigerators cannot be well matched with various types of refrigerators, and its structural stability is not good at the same time. Various failures, such as the suction cup falling, the wear of the mechanical arm, the opening and closing force is too large, the force point is uneven, the adjustability is not good, and the refrigerator door cannot be well matched, etc., and the safety and stability factor of the equipment is low.

[0004] At the same time, in the process of communicating with the refrigerator testers, it was found that the trajectory of the rotating arm of the test module of the existing refrigerator cannot match the trajectory of the refrigerator door switch. The phenomenon of falling off or even hitting, so that the test is forced to stop, and it needs to be reinstalled, and even the refrigerator hinge is damaged abnormally due to the track error. The uneven force on the force arm caused by the uneven force on the refrigerator door leads to power damage, and it is impossible to realize the simultaneous door opening and closing test of the upper and lower doors at the same time, which cannot match more and more models of refrigerator doors with different structures and appearances.

[0005] In addition, the existing refrigerator test system has low safety and stability performance, insufficient ability to deal with power outage risks, remote control and real-time control performance, and incomplete automation and intelligence, so it is urgently needed to improve
