Abstract

The invention relates to the technical field of test equipment, and discloses a self-alignment uninterrupted door opening machine for refrigerator door tests. The self-alignment uninterrupted door opening machine comprises a fixed connection device, a door opening connection device, a power device, an uninterruptible power supply and a self-alignment device, wherein the fixed connection device isused for fixing a test refrigerator; the door opening connection device is used for connecting a refrigerator door; the power device is fixed on the fixed connection device and used for driving the door opening connection device; the uninterruptible power supply is used for supplying power to the power device; and the self-alignment is used for determining an installation position of the test refrigerator. The self-alignment uninterrupted door opening machine can avoid abnormal power supply conditions, provides stable and uninterrupted power supply, can effectively guarantee the precision of the installation position of the test refrigerator, solves the matching problem of the door opening and closing trajectories of the refrigerator, realizes the effect of rapidly matching refrigerators of various models, is convenient and rapid in installation, can open and close upper and lower doors of the refrigerator at the same time automatically and repeatedly, has high equipment safety and stability coefficient and low failure rate, is not likely to damage the refrigerator, is high in degree of automation, has simple structure, and is low in cost.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a self-aligning continuous door opening machine for refrigerator door testing. Background technique [0002] At present, automation equipment is 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 existing refrigerator door opening mechanism cannot be well matched with various types of refrigerators. At the same time, its structural stability is not good.

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.
