Problems solved by technology

[0003] Because the upper cover plate of the battery cell currently adopts the sealing welding process, irregular weld seams will be formed during the welding process. The height of the pole surface and the bottom of the battery cell is inconsistent, which will affect the welding quality of the subsequent module welding process, which will easily cause the unevenness of the battery core at the bottom of the module afte

Abstract

The invention discloses a battery cell height measuring device. The device comprises a battery cell fixing mechanism used for fixing a battery cell, a pole detection mechanism used for detecting the height from the pole face of the battery cell to the bottom of the battery cell and a cover plate detection mechanism used for detecting the height from the cover plate face of the battery cell to the bottom of the battery cell, one end of the battery cell is fixed to the battery cell fixing mechanism, and the other end of the battery cell is propped against the pole detection mechanism and the cover plate detection mechanism. The battery cell height measuring device can automatically measure the height from the pole face of the battery cell to the bottom of the battery cell, and the measured value can be displayed on a display screen in real time; meanwhile, the height from the cover plate surface of the battery cell to the bottom of the battery cell is automatically measured, the measured value is displayed in real time, and the problems that the welding quality of a PACK module is poor due to height inconsistency and the module is not firmly bonded with glue of a battery shell are solved.

Description

Technical field[0001]The present invention relates to the field of electrical core preparation, and more particularly to a battery height measuring device.Background technique[0002]With the continuous improvement of the dynamic lithium battery production technology, the appearance performance, quality, production process and production efficiency of lithium battery cells put forward higher requirements.[0003]Due to the current cover of the battery, the sealing welding process is used. Because of the non-rule of weld during the welding, it will cause the electrical core cover and the electrical core bottom height due to equipment, welding process, etc. due to the welding process. The pole curtain surface is inconsistent with the bottom of the electrical core, which will affect the welding quality of the subsequent module welding process, which is easy to cause the electrical core of the welding post-welded module, more welding slag, the existence of the blowpoint, and will also affec...
