Cutting device with rapid clamping function for energy storage material processing

Abstract

The invention discloses an energy storage material processing cutting device with a rapid clamping function, and particularly relates to the technical field of energy storage material processing.The energy storage material processing cutting device comprises a basic processing table, a sealing device is fixedly connected to the lower surface of the basic processing table, and two positioning retainers are fixedly connected into the sealing device; and the two ends of the fan are respectively clamped on the opposite surfaces of the two positioning retainers. By arranging the guide plate, the heating piece, the cutting device and the basic machining table, it is guaranteed that in the subsequent process of pushing the energy storage material to move, burrs of the heated energy storage material can be removed under the action of extrusion force; according to the cutting device, saw-toothed burr surfaces generated after cutting can be synchronously treated in the energy storage material machining process, the machining effect of the cutting device on the energy storage material is guaranteed, the situation of reworking during subsequent machining is avoided, meanwhile, the machining quality of the energy storage material is guaranteed, and the machining efficiency of the energy storage material is improved. And therefore, the precision of the cutting device for processing the energy storage material is improved.

Description

technical field [0001] The invention relates to the technical field of energy storage material processing, and more specifically, the invention relates to a cutting device for energy storage material processing with a fast clamping function. Background technique [0002] It can not only store energy, but also convert energy for demand. The most common energy storage materials are hydrogen storage alloys and materials for primary batteries (that is, primary batteries, which cannot be restored after being discharged), secondary batteries (that is, batteries, which can be recharged and restored for repeated use after discharge), and lithium-ion batteries are Secondary battery, the principle is that when the battery is charged, lithium ions are deintercalated from the positive electrode, and inserted into the negative electrode through the electrolyte and diaphragm. On the contrary, when the battery is discharged, lithium ions are deintercalated from the negative electrode, and ...

Problems solved by technology

However, there are a series of technical problems in the preparation of metal lithium negatives, such as sticking knife, bending, lithium strip extension and slippage, edge burrs, etc., and in the process of making laminated batteries, the die-cutting of the pole piece takes much longer than Lamination is time-consuming, leading to a sharp increase in the cost of labor, equipment, and environmental dehumidification required for experiments or production

At present, metal metal molds are mainly used for die-cutting of lithium battery pole pieces. The main materials of the knife molds are steel, iron, etc., and the metal lithium sticking is avoided by controlling the roughness of the knife mold edge. For example, the patent CN203091830U requires the stainless steel edge roughness to be lower than Ra0 .025, which leads to an increase in die processing costs; in addition, since steel, iron and metal lithium are all oxygen-friendly, iron-friendly, stone-friendly, and gas-friendly materials, they have a certain affinity at the atomic level, and there is atomic diffusion during contact , cannot fundamentally solve the problem of sticking knives

Patent CN201102099Y recognizes the problems caused by photo paper cutting lithium tape, and proposes to use polypropylene cutting knife, but this patent only considers from the perspective of replacing photo paper knife to improve die-cutting efficiency and yield, and fails to further analyze polypropylene knife cutting lithium tape The effect and reason of non-stick knife

Moreover, in the existing metal lithium strip cutting process, since there is no buffer, the upper knife die directly presses down without buffering and contacts with the lower knife die during die-cutting, resulting in damage to the blade, shortening the ser
