Description

Technical Field

[0001] This utility model belongs to the technical field of sheet material performance, and more specifically, it relates to a sheet flexibility measuring device. Background Technology

[0002] Products have many inherent characteristics, such as weight, density, and specifications, among which softness (flexibility) is one. Sometimes, softness is replaced by measurement parameters such as tensile strength. There are many devices on the market that can test softness and tensile strength, such as universal testing instruments, Shore hardness testers, and Leeb hardness testers. Shore hardness testers are more suitable for testing rubber, Leeb hardness testers are more suitable for testing steel, and universal testing instruments can test all material samples. However, in the incoming material inspection process of battery manufacturing plants, a problem arises: thin metal or plastic materials such as nickel strips on batteries have a certain degree of softness, and while their appearance and material are the same as previous materials, their feel is different, being softer than previous incoming materials. However, the feel cannot be used as a basis for indicating an anomaly. The limitations of existing technologies are: universal testing instruments can test the tensile strength, peel strength, and tensile strength of materials, but they are large and cost over 10,000 yuan per unit; hardness testers are convenient to use and inexpensive, but they are not suitable for testing soft deformation and are more suitable for measuring a single location on the material.

[0003] Existing technology includes a device titled "Flexible Measuring Equipment" with publication number CN117168277A. This technology discloses a flexible measuring device belonging to the field of link measurement technology. It includes a base, a measuring bracket slidably connected to the base, and two movably connected pin gauges (I and II). A limit component is provided on the base for fixing the link to be measured. An adjustment component is also provided on the base, and a coating and cleaning component is provided on the adjustment component. During measurement, this invention can automatically insert and remove support plates, automatically adapting to the bending and twisting of the link to be measured and compensating for displacement, eliminating the need for manual operation. It can adapt to different hole diameters and thicknesses on the link to be measured, making it widely applicable. It can automatically and evenly apply lubricant to the hole walls of the link to be measured. It can clean dust and impurities from the inner wall before measurement to prevent interference with the measurement. After measurement, it cleans the lubricant from the hole walls to prevent dust from adhering to the lubricant, ensuring the cleanliness of the link to be measured.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
