Device for measuring thickness of battery

Abstract

The invention discloses a device for measuring the thickness of a battery. The device comprises a base (1), wherein a to-be-measured battery is arranged at the top part of the base (1); the left end wall of the base (1) is connected with a side bracket (3); a dial gauge bracket (6) is transversally arranged on the left side at the top part of the side bracket (3); a dial gauge (13) is arranged at the top part on the right end of the dial gauge bracket (6); the bottom surface of the dial gauge (13) is connected with a dial gauge stick (14); and the dial gauge stick (14) is located right above the base (1). The invention discloses the device for measuring the thickness of the battery; and the device rapidly efficiently measures the thickness of the battery, can efficiently avoid measurement errors caused by the deformation of the battery, greatly improves the thickness measurement efficiency for the battery, further reduces the manufacture cost of the battery, improves the whole production quality of the battery, and broadens the market prospect of the battery manufacturer.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery thickness measuring device. Background technique [0002] At present, lithium-ion batteries have the advantages of high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras, and laptop computers, but also widely used in electric vehicles and electric bicycles. And large and medium-sized electric equipment such as electric tools. [0003] For lithium-ion batteries, manufacturers need to measure their thickness with a caliper before leaving the factory, so as to judge whether the battery is deformed through the measured value, so as to judge whether the battery has an opposite sex, prevent bad batteries from entering the market, and improve the quality of the battery when it leaves the factory. In view of the fact that the thickness of different positions is differ...

AI Technical Summary

Problems solved by technology

In view of the fact that the thickness of different positions is different when the battery is deformed to different degrees, it is difficult to capture the highest point of the thickness of the battery with the existing method of measuring the thickness of the battery with a caliper, and it is difficult to control the strength of the measurement, so that the actual thickness of the battery cannot be accurately obtained , it is easy to cause measurement errors, it is impossible to effectively detect the abnormality of the battery, to control the quality of the battery, and at the same time, the measurement efficiency is low, which seriously affects the production speed of the battery
