Description

Technical Field

[0001] The utility model relates to the technical field of testing and measurement, and more specifically to a wear-resistant tester for battery shrapnel. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] In recent years, the application of electronic tags in supermarkets has increased significantly, and with it comes a sharp increase in the demand for battery shrapnel, a key component used to connect the electronic tag circuit to the battery. One application mode of electronic tags is rail installation, that is, the electronic tag is powered by sliding into a rail with a power supply. In this usage scenario, the battery shrapnel needs to slide along the rail frequently to adapt to different needs, which puts higher requirements on the wear resistance of the shrapnel coating. In order to ensure the continuous conductivity of the battery shrapnel during the sliding process, a conductive and wear-resistant coating is usually applied to the surface of the shrapnel. In view of the additional wear challenges caused by sliding, it is particularly necessary to develop a tester specifically for the wear resistance of the battery shrapnel of the rail-type electronic tag, in order to evaluate and ensure the long-term performance of the coating in practical applications.

At the same time, the displacement control during the test is not precise enough to ensure the accuracy and consistency of the friction displacement. In view of these shortcomings, we set out to develop a new wear tester to overcome the above difficulties and achieve dynamic monitoring of force values ​​and high-precision control of friction displacement during wear tests.
