Automatic shearing machine for Li-Mn button battery diaphragm paper

Abstract

A disclosed automatic shearing machine for Li-Mn button battery diaphragm paper comprises rack assemblies, a paper cutting mechanism, a pneumatic control system and an electrical apparatus control system; the frame assemblies comprise a work bench, a supporting plate, a table top, a rack, a bottom plate and anchors; the pneumatic control system and the electrical apparatus control system are disposed on the bottom plate; and the paper cutting mechanism is disposed on the work bench which is fastened on the supporting plate. The height of the whole equipment can be adjusted by the anchors. The paper cutting mechanism comprises three parts which are connected via the work bench, wherein a first part is a paper supplying part, a second part is a negative-electrode-casing transmitting part, and a third part is a paper-cutting mould base.

Description

technical field [0001] The invention relates to automatic production technology in the field of machinery, in particular to an automatic cutting machine for separator paper of lithium-manganese button batteries. Background technique [0002] Lithium fluoride carbon, lithium manganese and lithium iron button batteries are high-performance batteries developed in recent years. They are low-carbon economy and new energy products that have been upgraded internationally. The development and characterization of the lithium manganese dioxide system was carried out almost simultaneously with the lithium fluoride system, and the lithium fluoride system was selected for high power, while the lithium manganese dioxide was selected for high capacity. Compared with carbon fluoride, manganese dioxide can provide a larger capacity power supply, so lithium manganese button batteries have broad market prospects in various fields. [0003] At present, the automatic cutting machine for separat...

Problems solved by technology

[0003] At present, the automatic cutting machine for separator paper in the production line of lithium-manganese button batteries produced in China can only cut out a bowl-shaped separator paper for one negative electrode case each time, which cannot give full play to the advantages of the automatic production line of lithium-manganese button batteries.

As described in the patent CN200810024738, the production and assembly line of a lithium-manganese button battery can only punch out a piece of circular diaphragm with a diameter corresponding to the bottom surface of the negative electrode shell cavity by cutting the diaphragm paper part at a time, although the diaphragm can be realized The automatic cutting of the sheet and placing it in the negative shell, but this circular diaphragm sheet may cause a short circuit

Another example is a battery separator paper automatic cutting machine described in the applicant’s prior patent CN200810052503.8, the diameter of the separator paper cut out is larger than the inner diameter of the negative electrode case, when the separator paper is pressed into the negative electrode by the paper cutting mechanism A bowl-shaped structure can be formed behind the shell, which effectively avoids the occurrence of possible short circuits, but the shearing machine can only cut out one diaphragm paper at a time

There is a great demand for lithium-manganese button batteries at home and abroad, but the existing lithium-manganese button battery separator paper automatic cutting machine equipment can no longer meet the needs of batch automated production of lithium-manganese button batteries
