Abstract

The invention relates to the technical field of waste battery recycling treatment, and discloses an automatic device for separating attachments on the surfaces of positive and negative pole pieces of a waste power lithium battery, the automatic device comprises a rack, the top of the rack is provided with a feeding conveying belt device, and the feeding conveying belt device is provided with a plurality of battery pole piece placing groove assemblies which are arranged at equal intervals; a feeding conveying belt device is arranged on the support, a grinding device is arranged above the feeding conveying belt device, a grinding tool feeding device is fixedly arranged on the support, a dust suction device is arranged on the rear side of the grinding device, a discharging conveying belt device is fixedly arranged on the support, a guide groove is formed in the discharging end of the feeding conveying belt device, and a material removing device is arranged on one side of the discharging end of the discharging conveying belt device. A mechanical arm device is arranged on the other side of the discharging end of the discharging conveying belt device. According to the invention, continuous feeding of the to-be-separated electrode plates, continuous grinding and separation of attachments on the surfaces of the battery pole plates, negative-pressure adsorption and collection of separated substances, and continuous discharging, automatic turning and feeding of the separated and processed battery pole plates are realized.

Description

technical field [0001] The invention relates to the technical field of recycling and processing of waste batteries, in particular to an automatic device for separating surface attachments of positive and negative electrodes of waste power lithium batteries. Background technique [0002] Since the 21st century, new energy vehicles have become one of the key development directions for countries all over the world to achieve energy conservation and emission reduction. By 2020, my country's annual output of new energy vehicles has reached 2 million, and the cumulative output has exceeded 5 million. The service life of power lithium batteries on electric vehicles is generally 5-8 years. After 2018, power lithium batteries on new energy vehicles will begin to enter the stage of large-scale retirement. [0003] If the decommissioned power lithium battery is not handled properly, it will cause great harm to the ecology. The power lithium battery is mainly composed of positive elect...

Problems solved by technology

[0004] In the prior art, the separation between the surface layer of the waste battery pole piece and the battery pole piece is usually achieved by mechanical shock or impact after heating. Not only is the separation not sufficient and thorough, but it will also cause deformation or damage to the battery pole piece itself. The recycling of battery pole pieces is inconvenient; and the particle size of the separated surface matter is uneven, with large individual differences. Further grinding and crushing is required to achieve sub
