Automatic OCV test equipment for flexibly packaged power lithium ion battery

Abstract

The invention relates to automatic OCV test equipment for a flexibly packaged power lithium ion battery. The automatic OCV test equipment comprises a rack, a movement mechanism unit, a tray conveyingunit, a battery tray, an OCV test unit and a controller, wherein the rack is used for mounting a working part; the movement mechanism unit is arranged in a mounting cavity of the rack and comprises aprobe plate component and a movement mechanism; the tray conveying unit is used for placing a tray and conveying the tray to a tray conveying line outside the rack; the OCV test unit is used for acquiring an OCV parameter of a to-be-tested flexibly packaged power lithium ion battery; the controller is arranged in the mounting cavity of the rack; the control terminals of the movement mechanism unitand the tray conveying unit are respectively electrically connected with a corresponding pin of the controller; and the signal output terminal of the movement mechanism unit is electrically connectedwith the OCV test unit, and the signal output terminal of the controller is connected with the signal input terminal of an external server by virtue of a signal. The automatic OCV test equipment provided by the invention has the beneficial effects that the automatic OCV test equipment can be compatible with multiple battery sizes, automation production efficiency is improved, automatic detectionon the OCV parameter of the battery is realized and operation is easy.

Description

technical field [0001] The invention relates to an automatic OCV testing device for a soft pack power lithium ion battery. Background technique [0002] After the soft-pack power lithium-ion battery is decomposed into capacity (the surface of the soft-pack power lithium-ion battery has a barcode), it needs to be tested for OCV (Open Circuit Voltage, open circuit voltage) to obtain the K value of the soft-pack power lithium-ion battery , Current, voltage, capacitance and other parameters, in order to sort out the batteries with unqualified parameters, so as to ensure the quality of the finished battery. In traditional technology, the OCV testing process is all done manually, which will lead to the following disadvantages: First, a single device cannot automatically be compatible with batteries of various sizes, and the production of batteries of new sizes requires customizing new equipment, which not only costs It is high and occupies a large area; second, because each opera...
