Description

Technical Field

[0001] The present invention relates to an electro-deposition device, and more particularly to a linear jet electro-deposition device. Background Art

[0002] Electrodeposition technology is the foundation of metal electrolytic smelting, electroplating, and electroforming processes, and has broad application prospects in surface modification, the development of new materials for electrical and optical coatings, and other areas. Electroplating technologies include immersion plating and jet plating. Immersion plating is prone to concentration polarization, which affects the grain size and coating quality of the electroplated material. It is suitable for overall electroplating but has difficulty in achieving localized electroplating. Jet electroplating, on the other hand, can achieve localized electroplating with high quality. However, existing jet electroplating technology is often combined with CNC lathes to achieve flat metal plating. Only one surface coating can be plated on the carrier surface in one pass, which cannot meet the requirements of multi-layer plating of metal materials. Furthermore, the single electroplated shape limits its scope of application. Summary of the Invention

[0010] Among them, it also includes a carrier positioning device, which includes positioning blocks connected to the shell. The positioning blocks are arranged on both sides of the carrier, which can clamp the carrier to fix the position of the carrier and ensure that the carrier will not deviate in the upper and lower positions during the horizontal rolling out process.
