Problems solved by technology

In the existing technology, when cutting the pole piece, the pole belt must stop the conveying movement, otherwise it will cause the subsequent pole belt to be convex and deformed and affect the quality of the next cut pole piece, so the relevant conveying mechanism must be stopped periodically ,start up
Stopping the conveying action of the pole belt will inevitably reduce the efficiency of cutting pole pieces and increase the complexity of the system device

Abstract

The invention discloses a high-speed pole piece cutting device. The device comprises a die cutting bottom frame, a cam mechanism, a rolling feeding mechanism and a die cutting mechanism; the die cutting bottom frame is fixedly arranged on a machine tool or any one stable horizontal plane, the cam mechanism is arranged on the upper surface of the front end of the die cutting bottom frame, the die cutting mechanism is arranged on the upper surface of the rear end of the die cutting bottom frame, the cam mechanism and the die cutting mechanism are connected through a driven connecting rod, and arolling belt feeding mechanism is arranged in the die cutting mechanism. According to the high-speed pole piece cutting device, and a cutting method thereof, in the process that a pole belt is kept feeding moving, the pole belt is cut into a pole piece in the stipulated shape, continuous cutting is achieved, the pole belt does not need to stop feeding, the pole piece cutting efficiency is improved, when the cutting mold cuts the pole piece, the pole belt is kept static, feeding action is stopped, after cutting action is finished, the pole belt recovers the conveying action, the above action iscirculated, and pole piece cutting is carried out.

Description

technical field [0001] The invention relates to lithium battery production equipment, in particular to a high-speed pole piece cutting device. Background technique [0002] At present, with the extensive application of lithium batteries, lithium batteries have a complete and mature process flow from design to production. Among them, pole piece cutting is a very important production process. In the existing technology, when cutting the pole piece, the pole belt must stop the conveying movement, otherwise it will cause the subsequent pole belt to be convex and deformed and affect the quality of the next cut pole piece, so the relevant conveying mechanism must be stopped periodically ,start up. Stopping the conveying action of the pole belt will inevitably reduce the efficiency of cutting the pole piece and increase the complexity of the system device. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art, and pr...
