Full-automatic voltage internal resistance testing system

Abstract

The invention discloses a full-automatic voltage internal resistance testing system. The full-automatic voltage internal resistance testing system comprises a material frame cart, a transfer platformwith a plurality of material storage positions, a turntable mechanism with a plurality of working positions and a discharging platform. The full-automatic voltage internal resistance testing system further comprises: a multi-connected clamping jaw manipulator used for transferring battery cells in a cart material frame to the transfer platform; a feeding, sorting, visual positioning and monitoringrobot used for grabbing the battery cells on the transfer platform, carrying out visual positioning and detection on the battery cells and placing the qualified battery cells on the working station of the turntable mechanism; a tab shaping mechanism, a battery cell body temperature testing mechanism, a code scanning mechanism and a battery cell voltage internal resistance testing mechanism whichare arranged at each working position of the turntable mechanism and are respectively used for carrying out tab shaping, battery cell body temperature testing, code scanning and battery cell voltage internal resistance testing; and a discharging and sorting robot used for discharging the battery cells which are tested to be qualified from the turntable mechanism to the discharging platform. According to the test system, the voltage and internal resistance test efficiency of a large square cell is improved, and test data is stable.

Description

technical field [0001] The invention relates to the technical field of cell testing, in particular to a fully automatic voltage internal resistance testing system. Background technique [0002] In the prior art, the test of large-scale square batteries (mobile phone batteries) is manually detected, and human factors lead to unstable test data, and the efficiency of manual testing of voltage internal resistance is low; each part of the test is carried out on different devices Clamping the batteries is cumbersome; batteries of different specifications need to be tested on different types of components, and it is difficult to replace equipment components, and one-key changeover cannot be achieved, and the changeover speed is slow; the equipment has no insulation protection, no physical protection against electricity, and no software alarm And other multiple security protection mechanisms, not safe enough. [0003] To sum up, how to effectively solve the problem of low efficien...
