Abstract
The utility model relates to lithium battery manufacturing equipment, in particular to a pole piece brush device of a lithium battery automatic sheet-processing machine. The brush device is characterized by consisting of a bracket and brush sponge, wherein the bracket comprises a left bracket and a right bracket, which are connected with each other by a steel shaft; and the opposite surfaces of the left bracket and the right bracket are correspondingly provided with brush sponge respectively. The brush device is applied to the sheet-processing procedure in the production of lithium batteries; the brush device is fixed on the sheet-processing machine, the pole pieces pass between the left bracket and the right bracket when in tape transport, and the sides of the pole pieces are immersed into the brush sponge, so that the sides of the pole pieces are completely brushed, and simultaneously, the surfaces of the pole pieces are also brushed, namely the brushing of the pole pieces is completed in the advancing process of the pole pieces. The brush device adopts the mode of combining the side brushing and the surface brushing of the pole pieces, so that the pole powder on the sides of the pole pieces is thoroughly eliminated, the short circuit rate is lowered, the self-discharge rate of batteries is lowered, the manual brushing procedure of the pole pieces is saved, the production efficiency is improved, and the cost is lowered.
Description
Technical field
The utility model relates to a kind of lithium battery production equipment, is specially the pole piece brush dust device of the automatic pelleter of a kind of lithium battery.
Background technology
Advantages such as lithium ion battery has high working voltage, high-energy-density, has extended cycle life, non-environmental-pollution; Not only on portable communication apparatus and portable electric appts, be used widely; And be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, be the main direction of present each macrocell producer development.Positive/negative plate is the important component part in the lithium battery, and half-finished pole piece need be handled the utmost point powder on the pole piece after through automatic pelleter, and existing brush utmost point powder mode majority is artificial, has so just reduced operating efficiency, has increased production cost.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is to provide the technical scheme of the pole piece brush dust device of the automatic pelleter of a kind of lithium battery.
The pole piece brush dust device of the automatic pelleter of described a kind of lithium battery; This pole piece brush dust device matches with automatic pelleter; It is characterized in that described brush dust device is made up of support and brush dust sponge, support comprises left socle and right support, connects through the steel axle between left socle and the right support.
The pole piece brush dust device of the automatic pelleter of described a kind of lithium battery is characterized in that being equipped with the brush dust sponge respectively on the opposite face of described left socle and right support.
The pole piece brush dust device of the automatic pelleter of described a kind of lithium battery is characterized in that described left socle and right support are slidingly arranged on the steel axle.
The utility model is applicable to the film-making operation that lithium battery is produced, and this brush dust device is fixed in pelleter, passes during the pole piece tape transport in the middle of two brushes, and the pole piece side puts in brush, in pole piece advances process, accomplishes the work of brush sheet.The pole piece brush dust reduces short circuit ratio to reduce the utmost point powder on battery pole piece surface, reduces the self-discharge of battery rate, cuts the artificial brush dust operation of pole piece, enhances productivity, and reduces cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-left socle; 2-brush dust sponge; The 3-right support; 4-steel axle.
Embodiment
Below in conjunction with Figure of description the utility model is further specified:
The pole piece brush dust device of the automatic pelleter of a kind of lithium battery; This pole piece brush dust device matches with automatic pelleter; The brush dust device is that support and brush dust sponge 2 constitute, and this brush dust device is the brush of brush dust, and support comprises left socle 1 and right support 3; Be equipped with brush dust sponge 2 respectively on the opposite face of left socle 1 and right support 3, connect through steel axle 4 between left socle 1 and the right support 3 and be slidingly arranged on the steel axle.
The utility model is applicable to the film-making operation that lithium battery is produced; This brush dust device is fixed on the pelleter; (left socle and right support pole piece are equipped with on the steel axle to pass the centre of left socle and right support during the pole piece tape transport; Distance between left socle and the right support can be adjusted), (this moment, pole piece can be cut the brush dust sponge and make integral body imbed the brush dust sponge) sunk in the brush dust sponge in the pole piece side, guarantees that the pole piece lateral parts is brushed fully; The pole piece surface is also brushed simultaneously, promptly in pole piece advances process, accomplishes the work of pole piece brush dust.
The mode that the utility model adopts pole piece sidepiece brush dust to combine with surperficial brush dust is thoroughly removed the utmost point powder of pole piece side, has reduced short circuit ratio, has reduced the self-discharge of battery rate, has saved the artificial brush dust operation of pole piece, has improved production efficiency, has reduced cost.
