Abstract: A multifunctional apparatus of automatic punching, laminating, tape-preparing and cutting for a tailing end of a coiled material and a method associated therewith are provided. The apparatus is provided with a winding device and the coiled material. The coiled material is wound on a rotating shaft of the winding device. A robotic arm is disposed above the winding device. One end of the robotic arm is mounted with a punching, tape-preparing and cutting mechanism, and the other end thereof is rotatably connected to a centering and deviating-correcting mechanism fixed on a winding diameter tracking mechanism. The robotic arm is driven by a motor or a pneumatic cylinder or a hydraulic cylinder. The winding diameter tracking mechanism is slidably disposed on a rail of a rack. The apparatus and method can improve efficiencies of winding and jointing of coiled materials, and reduce production cost.

Abstract: An on-line automatic cleaning apparatus of slit extrusion type coating die for lithium battery and a method associated therewith are provided. The cleaning apparatus includes: a die lip, a coating steel roller, and a cleaning mechanism disposed therebetween. The cleaning mechanism includes a cleaning chamber which includes elongated sealing strips and a flow-guiding arc groove. Front and rear ends of the cleaning chamber are connected to an inlet sealing plate and an outlet sealing plate respectively. The flow-guiding arc groove is in contact with and presses upper and lower sloped surfaces of the die lip through the elongated sealing strips to seal and thereby define a closed cleaning tunnel. The inlet and outlet sealing plates are in contact with and press two ends of the closed cleaning tunnel respectively for circumferential sealing. An inlet and an outlet are connected to pipes having solenoid valves installed thereon.
