Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fatigue testing, and in particular to a fatigue testing system. BACKGROUND

[0002] At present, some products and devices with lids and buttons on the market need to be tested by fatigue testing to ensure their quality. Among them, the structure and types of cup lids are diversified, and the testing difficulty is greater. Therefore, taking a cup with a lid as an example. At present, the cup lids on the market that need to be tested by fatigue testing mainly include three common opening modes: threaded opening, elastic flip opening and top sliding opening.

[0003] The threaded opening cup has a threaded connection structure, and the cup is opened and closed by rotating the lid, which has good sealing performance, but the opening process is relatively cumbersome. The elastic flip opening cup uses the action of the elastic part, and only needs to be pressed or pushed slightly, and the lid can be flipped open, which is convenient to operate, but the elastic part may have problems such as elastic attenuation during long-term use. The top sliding opening cup opens the lid by sliding operation at the top. This design is usually more concise and smooth in appearance, but the sliding structure has high manufacturing precision requirements, and has the defect of relatively poor sealing effect.

[0004] No matter which type of cup described above, in order to ensure product quality, meet the use needs of consumers and safety standards, it must be subjected to strict fatigue testing. Fatigue testing aims to simulate the frequent opening and closing of the cup during actual use, and test the durability and reliability of the parts under repeated stress.

[0005] However, the current fatigue testing of the cup mostly relies on manual methods. When fatigue testing is performed manually, the tester needs to manually open and close the cup frequently, which not only has low efficiency, but also due to the differences in the force, frequency and method of operation of different testers, it is difficult to ensure the consistency and stability of each operation, resulting in a large error rate of the test results. This inefficient and error-prone manual fatigue testing method not only cannot accurately evaluate the actual quality and performance of the cup, but also consumes a lot of manpower, material resources and time cost, seriously restricting the product research and development and quality control efficiency of the cup production enterprise, and cannot meet the needs of modern manufacturing for efficient and accurate quality detection.

[0006] Therefore, it is urgent to develop an automatic fatigue testing technology or device that can overcome the defects of the current manual fatigue testing, to improve the efficiency and accuracy of the cup fatigue testing, ensure the reliability of the cup product quality, meet the market demand for high-quality cup products, and promote the healthy development of the entire cup industry.
