Device for separating battery diaphragm from positive and negative electrode plates

Abstract

The invention relates to the technical field of recycling of lithium-ion batteries, in particular to a device for separating a battery diaphragm from positive and negative electrode plates. The device comprises a fixed plate, wherein a motor is arranged at one side of the fixed plate; a pair of L-shaped swing arms and a pair of J-shaped swing arms are arranged at the left side and the right side of the other side of the fixed plate at an interval respectively; the pair of L-shaped swing arms is connected with each other through an L shaft; the pair of J-shaped swing arms are connected with each other through a J shaft; an L hairbrush is arranged between the lower parts of the two L-shaped swing arms; a J hairbrush is arranged between the lower parts of the two J-shaped swing arms; the fixed plate is respectively provided with three guide shafts and a winding shaft from top to bottom; the first guide shaft is located in a space which is surrounded by the L-shaped swing arms and the J-shaped swing arms; the second guide shaft is located at the end parts of the lower parts of the L-shaped swing arms; the third guide shaft is located below the end parts of the lower parts of the L-shaped swing arms; and the winding shaft is connected with the motor. The device is simple in structure and relatively low in cost; the battery diaphragm can be quickly separated from the positive and negative electrode plates; and great convenience is provided for subsequent recovery work.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery recycling, in particular to a device for separating battery diaphragms from positive and negative electrodes. Background technique [0002] Flexible packaging lithium-ion batteries use liquid electrolyte as the medium for the transmission of lithium ions between the positive and negative electrodes, and the outer packaging uses multi-layer plastic composite films. Since the soft-pack lithium-ion battery does not use a metal case, it has the advantages of good safety and high energy density, and the manufacturing process is simple, so the cost is low. Flexible packaging lithium-ion batteries are not only used in high-power demand fields such as electric vehicles, but also in high-energy demand fields such as electricity. With the rapid development of flexible packaging lithium-ion batteries, new problems have been brought about, that is, how to solve the scrapping and recycling of flex...
