Abstract

The present invention relates to a lithium battery tab length verifying device. The lithium battery tab length verifying device comprises a pedestal on which a first limiting boss used for limiting the displacement of one end of a lithium battery possessing a tab is arranged, an avoiding port used for avoiding a lithium battery tab is arranged on the first limiting boss, and a second limiting boss used for limiting the displacement of one end of the lithium battery not having the tab and a measuring tool used for measuring the length of the tab are also arranged on the pedestal. According to the lithium battery tab length verifying device of the present invention, the lithium battery is placed between the first limiting boss and the second limiting boss, thereby guaranteeing the fixed position of the lithium battery. The tab of the lithium battery is placed in the avoiding port, the length of the tab can be measured accurately by the measuring tool, and the data is provided for the subsequent analysis.

Description

technical field [0001] The invention relates to a device for checking the length of tabs of lithium batteries. Background technique [0002] Tabs are a raw material for the production of lithium-ion polymer batteries, such as mobile phone batteries, Bluetooth batteries, and notebook batteries used in daily life. The battery is divided into positive and negative poles, and the tab is the metal electric body that leads the positive and negative poles out of the battery cell. In the battery production process, measuring the size of the positive and negative tabs of the battery is a very important process before battery packaging. Batteries of different specifications have different process requirements for the size of the tabs. At present, in the battery production process, most companies usually rely on traditional measurement methods for the size detection of tabs, such as using tools such as micrometers and vernier calipers. The result has a large error. [0003] The Chin...
