Anode structure and method for electroforming ultra-thin metal mesh

Abstract

The invention discloses an anode structure and a method for electroforming a ultra-thin metal mesh, and belongs to the field of electro-deposition processing. The anode structure comprises a stirringpaddle, a linear ultramicro anode and a flexible electrical insulation layer, wherein the linear ultramicro anode is embedded in the center of the bottom plane of the stirring paddle, and the flexibleelectrical insulation layer is closely attached to the outer sides of the stirring paddle and the linear ultramicro anode. The anode structure is characterized in that equidistantly-distributed transparent narrow slits are formed in the part, attached to the bottom plane of the stirring paddle, and the linear ultramicro anode is divided into a plurality of ultramicro anode arrays by the transparent narrow slits, so that the current output under a single ultramicro anode is highly centralized and localized. The scanning deposition in two processing directions is carried out circularly and alternately in turn, and further multiple parallel strip metal layers in different directions are cross-stacked to form a braided metal mesh structure. The anode structure realizes the control of the sizeof the metal mesh by adjusting the width and spacing of the narrow slits, and realizes the high-quality and high-efficiency manufacturing of the metal mesh by the cooperative control of anode runningspeed and current density.

Description

technical field [0001] The invention relates to the technical field of electrodeposition processing, in particular to an anode structure and method for electroforming and manufacturing ultra-thin metal grids. Background technique [0002] Metal grid products with mesh characteristics, such as screening nets, filter nets, shielding nets, loading nets, spray sheets, etc., are widely used in screening, screening, filtration, separation, electromagnetic shielding and other fields. Regular hole shape, smooth hole wall, and high geometric shape consistency are important signs of high-quality metal mesh products. [0003] There are two main types of metal grids: wire woven and non-woven. The former has a wide range of applications in industrial production due to its simple preparation process, low cost, and convenient and diverse materials. However, its hole shape is poorly controllable, low geometric shape accuracy, irregular hole walls, many weaving knots, and uneven mesh surfac...

Problems solved by technology

However, when traditional electroforming manufactures metal grids, it is necessary to first use a high-cost photolithography process to prepare a patterned film structure, and then perform electrodeposition replication. That is to say, traditional metal grid electroforming is a kind of precision replication. process, therefore, this method relies heavily on the photolithographic film-making process with complex operation steps
