Abstract

The invention provides a tension test structure, and relates to the technical field of battery detection. The tension test structure comprises a driving element, a moving assembly, a tension detectorand a fixing clamp, wherein the driving element is connected with the moving assembly; an element to be detected is arranged on the fixed clamp and is connected with the moving assembly; the moving assembly moves under the effect of the driving element and exerts tension on the element to be detected; the tension detector is arranged on the moving assembly and is used for detecting the tension born by the element to be detected so as to judge whether the connection of the element to be detected is reliable or not. The tension test structure has the advantages that the operation is convenient;the test precision is high; the product qualification rate is favorably improved; the product quality and competitive power are improved.

Description

Technical field [0001] The invention relates to the technical field of battery detection, and in particular to a tensile test structure. Background technique [0002] At present, the key parameters of the electrical performance of lithium batteries, such as large internal resistance, excessive charging and discharging and other abnormal phenomena, are all related to the welding effect. In the production process of the battery, after the battery cell and the electrode plate are welded, if the correct test and inspection are not carried out, whether the welded battery cell is qualified or not will affect the electrical performance of the later battery. Moreover, without welding quality inspection, it is difficult to meet the requirements of product qualification rate. Summary of the invention [0003] In view of this, the object of the present invention includes providing a tensile test structure, in which the test piece is installed on a fixed fixture and connected with a mobile c...
