Cathode drum for electrolytic deposition

Abstract

Disclosed is a cathode roller for electrolytic deposition, in which a circumferential peripheral surface and side panels of the cathode roller are formed of a zirconium material having strong hardness, strength, and corrosion resistance to an electrolytic cell electrolyte, thereby preventing the circumferential peripheral surface from being formed into a composite oxide film by the electrolyte to adversely affect the quality of an electrolytic foil deposited from the cathode roller. According to the product, an outer side cylinder formed on the circumferential surface of the cathode roller protrudes towards the two sides of a side panel of the cathode roller; the present invention increases the width of a metal foil by increasing the contact area with an electrolyte in such a manner that both ends of the metal foil are fixed and supported, and accelerates the solidification speed from the outside to the inside with respect to external air to precipitate in a short time. In addition, the present invention is a cathode roller for electrolytic deposition in which holding rings having a plurality of holding pieces are formed on both sides of the inside of the cathode roller to maintain the firmness of the cathode roller.

Description

technical field [0001] The invention relates to a cathode roller, in particular to a cathode roller for electrolytic deposition which can obtain electrolytic foil from an electrolytic bath. Background technique [0002] With the gradual acceleration of the miniaturization of electrical appliances, electronics, and machinery, the lines assembled inside the machinery are also miniaturized. Furthermore, the lines formed on the PCB are gradually becoming ultra-thin. As electrolytic copper foil tends to be ultra-thin, high-quality electrolytic copper foil becomes more and more important. [0003] In order to obtain electrolytic foils such as copper, iron, chromium, nickel, etc., it is generally manufactured by many devices including cathode rolls and anode electrodes assembled in the electrolytic cell at a certain interval together with the cathode rolls. Insoluble roll-type cathode materials and insoluble anodes The electrolytic reaction is carried out while an electrolyte sol...

Expensive and difficult welds such as non-MIG tungsten shielded welding (TIG) are required

[0013] In particular, the formation of titanium on the circumference of the cathode roller is through the electrolyte of the electrolytic cell, which can maintain a certain degree of hardness, strength and corrosion resistance. rutile type), anatase type (anatase type) composite oxide film exists, which will affect the quality of the metal foil deposited by the rotating cathode roller
