Abstract

The invention discloses an integrated device for testing voltage and internal resistance of batteries and shaping and cutting battery lugs. Two groups of positive and negative probes are added on a strip-shaped press block which shapes the battery lugs, and the two groups of positive and negative probes are respectively connected to slots for an external test pen at the periphery of the device through leads; two positive slots and two negative slots are connected to positive test pens and negative test pens of an internal resistance tester; the shaping press block can be a Teflon component; the interval of the probes embedded in the shaping press block can be correspondingly adjusted according to different intervals of battery core lugs; before the battery lugs are cut, the shaping press blocks flatten the lugs, the positive and negative test probes are also pressed on the positive and negative lugs, and the voltage and internal resistance of the battery can be tested simultaneously; and scanning gun holding racks are respectively disposed at right side and left side of the device. According to the device, by designed modification, the divided operations of testing the voltage and internal resistance of the battery and shaping and cutting battery lugs can be combined; the production efficiency is improved; and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of lithium-ion battery processing, in particular to an integrated device for voltage internal resistance testing, shaping and cutting lithium-ion battery tabs. Background technique [0002] At present, when lithium-ion battery processing enterprises process and test batteries, in addition to shaping and cutting the tabs of lithium-ion batteries according to the required size, they also need to perform functional tests on the internal resistance of the battery voltage and scan barcodes to Ensure that the battery meets the requirements of the subsequent processing technology. At present, the shaping and cutting tabs and the voltage internal resistance testing process in the factory production line are separate operations, that is, they are completed by different operators, which increases the labor cost of the enterprise; and there is no need to test the battery with test leads Fix the fool-proof tooling, there is a pot...
