一种正极粉体锂化接触界面自动更新机构

Automatic updating mechanism for contact interface of lithiation of positive electrode powder

Abstract

The invention provides an automatic updating mechanism for a contact interface of lithiation of positive electrode powder. The automatic updating mechanism is placed in a constant-gaseous-environment catalyst case and comprises a lithiation disc, supports, a transmission base plate, a crossbeam, springs, mechanical lithiation teeth, fixing pins, stop nuts and a lithiation crossbeam, wherein the tail ends of the mechanical lithiation teeth are sleeved by the springs, then the mechanical lithiation teeth are inserted into corresponding holes in the crossbeam and then the stop nuts are screwed on the tail ends of the mechanical lithiation teeth; positioning pins protruding from the bottom of the lithiation disc are inserted into corresponding holes in the transmission base plate; and the lithiation crossbeam is placed on the support and the fixing pins are inserted. Preferably, after the tail ends of the mechanical lithiation teeth pass through the crossbeam, the stop nuts are connected with the tail ends of the mechanical lithiation teeth through threads. The mechanical lithiation teeth and the crossbeam are positioned via the stop nuts, and the stop nuts are pressed to the crossbeam via the pressure of the springs. The lithiation disc and the transmission base plate are positioned via cylindrical pins. Preferably, the lithiation disc and the supports are positioned via pins.
本发明的一种正极粉体锂化接触界面自动更新机构,置于封闭的“恒定气体环境触媒发生箱”中,包括锂化盘、支架、传动底盘、横梁、弹簧、机械锂化齿、固定销钉、限位螺母和锂化横梁;所述机械锂化齿尾部套入弹簧,再插入横梁对应孔中,然后在机械锂化齿尾端拧上限位螺母;所述锂化盘底部凸出的定位销插入传动底盘对应的孔中;锂化横梁置于支架上并插上固定销钉。优选的,机械锂化齿尾部穿过横梁后,限位螺母与机械锂化齿尾部采用螺纹连接。机械锂化齿与横梁采用限位螺母定位,限位螺母通过弹簧压力与横梁压合。锂化盘与传动底盘采用圆柱销定位。优选的,锂化横梁与支架采用销钉定位。
