Description

Waste battery feeding system for the whole industry chain Technical Field

The present application relates to the field of battery recycling technology, for example, to a waste battery feeding system for the entire industry chain.

Background Art

In the field of waste battery disassembly and recycling, after the scrapped lithium batteries are disassembled into battery cells, the battery cells need to be discharged. Considering the safety of the back-end process and transportation, the single poles of the battery cells are manually insulated and affixed with insulating tape after discharge. Since there are many types and specifications of discharged battery cells with different sizes, they are manually packaged on plastic pallets. Generally, six layers of batteries are placed, and the specifications and models of single-layer batteries are different. The packaged single pallets are then transferred to the aluminum shell battery crushing line for crushing and sorting, and the battery materials inside are recycled.

At present, the battery feeding process at the front end of the aluminum shell battery production line is basically manual. An operator uses a multimeter to measure the voltage of battery cells of different specifications and sizes on the battery tray. The battery cells with voltage exceeding the upper limit are selected and discharged again. Another operator manually carries the battery cells that meet the feeding requirements and puts them into the conveyor belt at the front end of the aluminum shell battery crushing line, and then transports them to the crusher for crushing and sorting. This feeding method requires at least two people to operate, and only for battery cells that have been insulated after discharge. The weight of large-capacity battery cells reaches 5kg. Manual feeding leads to high labor intensity; and only one cell can be carried at a time, so the feeding efficiency is low.

The waste battery feeding system is configured as follows: the battery cells are sequentially passed through the glue grinding device 2 to remove the glue on the poles of the battery cells, the voltage measuring device 3 measures the voltage of the poles, and then the poles are insulated by the insulation treatment device 5, the qualified cell grabbing device 6 transfers the battery cells with qualified voltage to the first conveyor line 200, and the unqualified cell grabbing device 7 transfers the battery cells with unqualified voltage to the second conveyor line 300. Through the above-mentioned method, the automated operation of battery cell feeding is realized, the labor intensity of personnel is reduced, and the feeding efficiency is improved. In this embodiment, the voltage of a qualified battery cell is lower than 2.5 volts, otherwise the voltage of the battery cell is deemed unqualified.

The battery clamp is provided with a rubber grinding device, a voltage measuring device, an insulation treatment device, a qualified monomer grabbing device and an unqualified monomer grabbing device in sequence on the support frame along the circumference of the workbench. A first conveyor line is provided on one side of the qualified monomer grabbing device, and a second conveyor line is provided on one side of the unqualified monomer grabbing device. When feeding, the battery monomer is first transferred to the battery monomer clamp manually, and then the workbench is started to rotate. The workbench will drive the battery monomer clamp with the battery monomer to grind the rubber, detect the voltage and perform pole insulation treatment at the rubber grinding device, voltage measuring device and insulation treatment device in sequence. Finally, if the voltage test of the battery monomer is qualified, the battery monomer is transferred to the first conveyor line for crushing through the qualified monomer grabbing device. If the voltage test of the battery monomer is unqualified, the workbench continues to rotate one station to the unqualified monomer grabbing device, and the unqualified monomer grabbing device transfers the unqualified monomer to the second conveyor line for re-discharging. In this process, as the workbench rotates, detection and sorting can be carried out continuously, and the staff can continuously load the materials. Through the above method, the automated operation of battery cell feeding is realized, the labor intensity of personnel is reduced and the feeding efficiency is improved.

The above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods exhaustively here.
