Stripper

Abstract

The invention discloses a glue stripping machine, which includes a conveying device, a first glue stripping device, a second glue stripping device and a dust removal device; The stripping devices are all set on the transmission path of the conveying device. The first stripping device and the second stripping device simultaneously peel and rewind the adhesive paper pasted on the front and back sides of the pole piece; the dust removal device removes the dust generated during the stripping process. to remove. The adhesive stripping machine of the present invention cooperates with the first adhesive stripping device and the second adhesive stripping device, and can simultaneously realize the tearing and peeling of the adhesive paper pasted on both sides of the polar piece, effectively improving the stripping efficiency. The dust generated during the gluing process is removed to avoid the situation that the dust will pollute the pole piece, thereby ensuring the quality of the battery after being processed into a battery.

Description

technical field [0001] The invention relates to the technical field of battery production and processing, in particular to a glue stripping machine. Background technique [0002] Lithium-ion battery is a high-performance secondary battery. Lithium-ion battery has high working voltage, high specific energy, small size, light weight, low self-discharge rate, no memory effect, long cycle life and is not easy to pollute the environment. Advantages, therefore, are widely used in digital products such as mobile communication equipment, notebook computers, camcorders, PDAs (personal digital assistants) and digital cameras. At the same time, they are also used in power tools, electric bicycles, electric vehicles, storage energy, torpedoes and missiles. The quality of lithium-ion batteries has a crucial impact on the operation and service life of electronic products, electric bicycles and electric vehicles. Therefore, the requirements for battery quality are increasing day by day. ...

Problems solved by technology

In recent years, the manufacturing technology of lithium-ion batteries has made great progress. Lithium-ion batteries mainly include battery cores and electrolytes. Battery cores are generally composed of positive pole pieces, negative pole pieces and diaphragms. The pole piece and the separator are stacked together, and the separator is arranged between the positive pole piece and the negative pole piece. The three can be wound to form a wound battery pole core or stacked to form a laminated winding core. The existing pole piece (Including positive pole piece and negative pole piece) In the production process, it is necessary to carry out coating treatment on some areas of the surface of the pole piece, and the parts that do not need to be coated are pasted with various adhesive papers to achieve protection and insulation. Purpose, after the coating is finished, it is necessary to peel off the glued paper from the pole piece. At present, most of the methods of peeling off the glued paper pasted on the coated pole piece material tape are manually peeled off the coated pole piece. The adhesive tape on the sheet material tape is torn and peeled off, and the adhesive tape pasted on the sheet material tape is manually torn off, and the peeling speed is slow, especially for the sheet material tape with adhesive tape on both sides, manual peeling requires The adhesive tape pasted on the front and back sides of the first pole piece material tape can be peeled off twice, that is, the adhesive tape pasted on one side of the lower pole piece material tape is torn off first, and then the adhesive tape pasted on the other side of the lower pole piece material tape is torn off. The production efficiency is greatly reduced. Moreover, in the process of tearing and peeling off the adhesive tape pasted on the pole piece material tape, a large amount of dust will be generated. If it is not removed in time, the dust will be adsorbed on the pole piece material tape, causing damage to the pole piece. Pollution, so that the quality of the battery after being processed into a battery cannot be guaranteed
