Problems solved by technology

[0003] In order to solve the above-mentioned technical slitting machine when cutting and segmenting the metal lithium plate, the metal lithium plate is driven forward by the winding device. Because the metal lithium is soft, the winding device pulls the lithium strip, and the pulling force is large, which is easy to cause the metal behind The lithium plate is deformed, and the surface of the lithium plate is uneven. When cutting, it cannot advance along the original path, so that burrs are generated on both sides of the lithium strip during cutting. The lithium strip is directly processed into a pole piece, and the pole piece is installed on the negative electrode of the battery, which is easy Cause battery leakage, make the voltage of the battery low, and affect the use of the battery. The invention provides a lithium battery slitting machine

Abstract

The invention discloses a slitting machine for a lithium battery. The slitting machine structurally comprises a rack, a winding shaft, supporting rods and a slitting roller. The winding shaft is fixedto the middle lower portion of the front face of the rack, the supporting rods are fixedly embedded in the rack, the slitting roller is installed in the middles of the inner sides of the rack. When ametal lithium plate is slit, the winding shaft pulls a lithium strip, so that the metal lithium plate behind is prone to deformation. The surface of the lithium plate is uneven, clamping blocks on the two sides of a blade make contact with the uneven bottom face of the lithium plate, so that when the lithium plate is slit, the top of the lithium plate is flattened firstly through a flattening block, the lithium plate moves forwards flatly, the unevenness of the surface of the lithium plate is reduced, the lithium plate advances along an original path during cutting, burrs generated on the twosides of the lithium strip are reduced during cutting, and the battery can be used normally. As a small number of burrs exist after the lithium plate is slit, by brushing away the burrs on the two sides of the lithium strip through brushing plates on the two sides of a top plate, the burrs on the two sides of the lithium strip are reduced, the processing process of the lithium strip is reduced, and the lithium battery is safer in the using process.

Description

technical field [0001] The invention belongs to the field of slitting machines, and more specifically relates to a slitting machine for lithium batteries. Background technique [0002] Due to the high power storage capacity of lithium batteries, they are widely used in daily life. Lithium batteries are processed and combined with metal lithium and manganese dioxide. Metal lithium is used as the pole piece of the negative electrode. In order to make the pole pieces the same size, by using The cutting knife of the slitting machine segments the lithium metal plate; when the slitting machine cuts the metal lithium plate into segments in the prior art, the metal lithium plate is driven forward by the winding device. Pulling the strip, the pulling force is strong, it is easy to cause the deformation of the metal lithium plate behind, the surface of the lithium plate is uneven, and it cannot move forward along the original path when cutting, so that burrs are generated on both side...
