Description

Technical Field

[0001] The utility model relates to the technical field of peeling force testing, in particular to a clamp of a peeling force testing fixture. Background Art

[0002] The relationship between peel strength and peel force. Peel strength refers to the maximum force generated by the combination of the sample surface and the adhesive in the mechanical peeling test. Peel strength tests the peel strength index of adhesive products, which can reflect the bonding strength of the material through scientific data. It is an important reference for controlling the bonding firmness of adhesive products during use. The basic concept of peel force test is the size of the peeling force between two interfaces. Peel force test can be used to evaluate the bonding strength of various materials and adhesives.

[0003] At present, in order to test the peeling force of adhesive products with different adhesive strengths, the adhesive products are usually bonded on the surface of the test board, and then the test board is clamped and fixed by a fixture. However, when the current fixture is used to position and clamp the test board, it is not convenient to adjust the positioning size. There are limitations when positioning and clamping test boards of different specifications. Different fixtures need to be replaced, thereby reducing the flexibility of positioning and clamping the test board. For this reason, we provide a fixture for peeling force test fixture to solve the above problems. Utility Model Content
