Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to a high-efficiency continuous door opener for refrigerator door switch durability tests. Background technique [0002] At present, automation equipment is used more and more frequently in industrial production. How to relieve workers from heavy work [0003] Unwind and make productivity a top priority. 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. [0004] 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

[0004] 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.

[0005] In addition, 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 cannot 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.
