Heat shrinking technology and device for improving membrane wavy edge

Abstract

The invention provides a heat shrinking technology for improving a membrane wavy edge. The heat shrinking technology includes the following steps that rewinding rollers are prepared, a plurality of shrinkable buffer strips are arranged on the outer surfaces of the rewinding rollers at equal intervals, and all the buffer strips and the rewinding rollers are parallel in the axial direction; 2, membranes are wound around to the rewinding rollers provided with the buffer strips; 3, the rewinding rollers wound with the membranes are baked at the certain temperature, and baking is kept for certain time; 4, the baked membranes are taken out and cooled at the normal temperature; 5,the surfaces of the cooled membranes are coated with slurry with the certain thickness. The heat shrinking technology and device have the advantages that the membranes are even accordingly, the poor waves are reduced after the membranes are coated, the over-specification radian and the over-specification size after the membranes are cut to small strips are decreased, the superior product rate of the membranes is increased, production resources are reasonably used, and waste is reduced.

Description

technical field [0001] The invention relates to lithium battery manufacturing technology, in particular to a heat shrinking process and a heat shrinking device for improving the isolation of corrugated edges. Background technique [0002] At present, in the production and manufacturing process of domestic diaphragms, due to the uneven tension of the diaphragm and the failure of tension control, the diaphragm has serious wave defects after the finished diaphragm is shipped, and the wave defects appear after the diaphragm is coated, which affects the curvature of the diaphragm after it is cut into small strips. , The size exceeds the specification, and eventually the diaphragm cannot be used, resulting in waste of resources and increasing the production cost of the enterprise. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a heat shrinking process and a heat shrinking device for improving the isolation of the wa...
