Automatic slitting device for lithium battery core pole piece

Abstract

The invention discloses an automatic slitting device for a lithium battery core pole piece, and relates to the technical field of slitting devices. The automatic slitting device comprises a fixed box,a first motor is installed inside the fixed box, the output end of the first motor is connected with a driving roller, the outer wall of the driving roller is fixedly connected with a hobbing cutter,a silica gel heating piece is installed inside the hobbing cutter, a driving wheel is connected to the position, located on the outer wall of the driving roller, inside the fixed box in a sleeving mode, a driven wheel is connected to the position, located at the bottom end of the driving wheel, inside the fixed box, the inner wall of the driven wheel is connected with a driven roller, and a groove is formed in the outer wall of the driven roller. According to the automatic slitting device, electric push rods, a supporting plate and a sliding groove are arranged, and when a cut pole piece bodymoves to the top end of the supporting plate at the top end of a collecting box, a PLC controller controls a switch to start the three sets of electric push rods, so that the three sets of electric push rods are contracted, the supporting plate is controlled to descend by a certain distance, the cut pole piece body is stored in the sliding groove, and the cut pole piece body is stored and arranged.

Description

technical field [0001] The invention relates to the technical field of cutting devices, in particular to an automatic cutting device for pole pieces of lithium batteries. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. When the lithium battery is working, it needs a pole piece to conduct electricity. slices are processed. [0003] The existing pole piece automatic cutting device cannot fix the pole piece to prevent the pole piece from shaking when cutting, so that the cut part of the pole piece is uniform and reduces the success rate of pole piece production. The cutting device is inconvenient for cutting, which affects the production efficiency of the pole piece, and cannot arrange and store the pole piece after production, which is convenient for the staff to collect. Contents of the invention [0004] The purpose of the p...
