Abstract

The invention discloses a battery core tab calibration device, which comprises a support, two CCD detectors mounted on the support, a base plate, a width adjusting cylinder, two stepping motors and two clip assemblies. The width adjusting cylinder is disposed on the base plate and is used for adjusting the distance between the two clip assemblies. The CCD detector is configured to detect deformation data of a battery core tab. Each clip assembly comprises a pair of mechanical clips. Each stepping motor is used for adjusting the angle of the mechanical clips for tab correction according to thedetected deformation data of the battery core tab. According to the battery core tab calibration device, after detecting tab deformation curvature and parallelism and the like through CCD, the tab iscorrected accurately, thereby effectively ensuring size range of the tab passing through a bus-bar hole, and improving the cases of defects and rework of the tab passing through bus-bar hole in the prior art. The device has the advantages of full-automatic operation, automatic detection, automatic calibration, no need of human intervention and no safety hazard.

Description

technical field [0001] The invention relates to the technical field of cell preparation, in particular to a cell tab calibration device. Background technique [0002] In the process of assembling a single cell into a battery pack, the positive and negative of the cell must pass through the 44mm*2mm (length*width) busbar hole, and the general size of the cell tab is: 40mm*0.2mm (Length*Thickness), the maximum variation of the tab is allowed to be length <4mm, width <: 1.8mm, so as to ensure that the tab passes through the busbar hole; currently the tab is flattened to shape the tab, but due to the tab It is a metal structure with relatively strong resilience. After the tabs are reshaped, the deformation of some battery tabs cannot achieve the effect of <4mm in the length direction and <1.8mm in the width direction, so frequent rework is required. [0003] The currently used flattening technology has a relatively poor effect on the shaping of the tabs, resulting i...
