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 existing refrigerator door opening mechanism cannot be well matched with various types of refrigerators. At the same time, its structural stability is not good. In a batch of tests lasting tens of thousands of times during the durability test, various failures of the equipment itself often occurred. For example, the suction cup is dropped, the mechanical arm is worn, 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 movement trajectory of the existing refrigerator door opener's rotating arm and the refrigerator door switch trajectory could not be well matched. The existence of trajectory errors caused the rotating arm, suction cup and refrigerator door to fall off or even The phenomenon of impact caused the test to be stopped and reinstallation was required, and even the refrigerator hinge was damaged abnormally due to the trajectory error. At the same time, the existing door opener still had a suction cup that could not freely adjust its position on the entire surface of the refrigerator door, resulting in force on the refrigerator door. The uneven force on the force arm caused by unevenness 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. It cannot match more and more models of refrigerator doors with different structures and appearances, and urgently needs improvement.
[0005] In addition, since the refrigerator door test is generally more than 10,000 times, the test period is long, and the risk of power failure is relatively high. The existing door opener is not capable of coping with the risk of power failure, and urgently needs to be improved.

Abstract

The invention relates to the technical field of test equipment and discloses an uninterruptible power supply door operator for refrigerator door test. The uninterruptible power supply door operator comprises a fixation connection device for fixing a test refrigerator, a door opening connection device for connecting a refrigerator door, a power device fixedly arranged on the fixation connection device and used for driving the door opening connection device, and an uninterruptible power supply module for providing power supply to the power device. The uninterruptible power supply door operator can prevent the case of power supply abnormity, provides steady and uninterrupted power supply, realizes fast matching of various types of refrigerators and well solves the problem of refrigerator dooropening and closing track matching, is convenient and fast to install, can realize automatic repeated opening and closing of upper and lower doors of the refrigerator, and is high in safety stabilitycoefficient, low in failure rate, not easy to damage the refrigerator, high in automation degree, simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an uninterruptible power supply door opener for refrigerator door testing. Background technique [0002] At present, automation equipment is used more and more frequently in industrial production. How to free workers from heavy work has become the primary task of improving productivity. In the test of the hinge of the refrigerator door, faced with the tedious and tedious work of repeatedly opening and closing the door. At present, this action of repeatedly opening and closing the door is mainly done manually, the work is cumbersome and boring, and the test efficiency is low. [0003] The existing refrigerator door opening mechanism cannot match various types of refrigerators well, and its structural stability is also not good. For example, the suction cup is dropped, the mechanical arm is worn, the door opening and closing force is too large, the force point is uneven...
