An instrument for testing battery solder joints

Abstract

The invention relates to the field of battery detecting, in particular to a battery welding spot detecting instrument. The battery welding spot detecting instrument comprises a collecting mechanism, apushing mechanism, a base, a display screen, a tensile testing mechanism, a cutting mechanism, battery panels and a clamping mechanism. According to the instrument, the battery panels to be detectedare disposed inside a container, and a conveyor belt rotate to drive a pushing rod to push the battery panels to move to the position to be detected, so that automatic and circulating feeding is realized, the degree of automation is high, and the instrument is suitable for batch detection; when the detection is performed, data lines of the battery panels are fixed by the clamping mechanism, then the pulling force is applied by pushing, the abnormality is detected at welding spots under the condition of continuously increasing the pulling force, and recording is performed by camera shooting, sothat the operation is simple, and the instrument can accurately and intuitively detect whether the welding spots are firm; and after the detection is completed, the panels of different quality can bequickly separated without manual separation, so that the overall operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of battery testing, in particular to a battery solder joint testing instrument. Background technique [0002] A battery refers to a cup, tank, or other container or part of a composite container that contains an electrolytic solution and a metal electrode to generate an electric current. It is a device that can convert chemical energy into electrical energy; it has a positive pole and a negative pole. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy; such as solar cells; the performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using the battery as an energy source can provide stable voltage, stable current, and long-term stable power supply.

AI Technical Summary

Problems solved by technology

[0003] During the battery production process, it is necessary to weld the positive and negative materials of the battery on the battery cell. After the welding is completed, perform a tensile test on the welding point, and then observe whether there is a quality problem in the welding point; in the prior art, the detection of the welding quality of the welding point Usually carried out manually, manual detection is not only inefficient, but also prone to omissions and errors
