Separating device and method of waste lithium ion battery case and roll core

Abstract

The invention discloses a separating device and separating method of a waste lithium ion battery case and a roll core. The separating method comprises the following steps: cutting a battery to remove a top cap at the top end face; a material-picking manipulator grabbing and clamping the battery through a material-picking telescoping assembly with adjustable length, wherein the top end face of the battery is towards the outside of the manipulator; the material-picking telescoping assembly shrinking a first predetermined distance; an accelerative rotation assembly driving the material-picking manipulator to rotate with a first predetermined angle so as to partially separate the roll core from the shell; a blanking manipulator grabbing partially separated roll core through a blanking telescoping assembly with the adjustable length; the blanking telescoping assembly shrinking a second predetermine distance until the roll core is completely separated from the shell. The separation of the battery shell and the roll core is finished by use of the separating device with simple structure, a feasible scheme is provided for recycling the lithium ion battery, and the recycling of the batteries in different models can be realized through the change of the manipulator.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a device and method for separating waste lithium-ion battery shells and winding cores. Background technique [0002] Lithium-ion batteries have the advantages of high working voltage, long cycle life, high energy density and small self-discharge, and are widely used in mobile communications, computers, instrumentation and electric transportation, including electric bicycles and electric vehicles. As personal consumer goods and power batteries, the annual production and use are huge, and maintain a high growth rate. The next few years will usher in a peak period for the recycling of used lithium-ion batteries. Scrap batteries contain metal substances such as copper and aluminum, as well as rare metals such as lithium and even cobalt and manganese. If they are not recycled, it will not only cause a waste of resources, but also cause great pressure on the environment....

Problems solved by technology

[0004] The method of shell separation has also been reported. In the patent CN204885356U, the core is pulled out by clamping the tabs with a clamp. However, when the battery top cover is cut, the tabs and the shell are on the same surface. The interference of the body is not conducive to the separation of the core and the shell
