Embodiment approach 1

[0040] Electroforming is a special processing method that uses the principle of electrochemical deposition of metals to accurately replicate some complex, fine or special-shaped workpieces. In the electroforming process, the uniformity of the thickness of the electroforming layer is related to factors such as current density, electroforming time, temperature, anode area, concentration of the electroforming solution, and stirring of the electroforming solution. In order to improve the quality of electroforming, it is necessary to strictly control the electroforming The temperature, ion concentration, and current density of the solution, and in order to avoid concentration polarization of the solution, rough surface of the workpiece or occurrence of pinholes, etc., the electroforming solution needs to be continuously filtered and stirred. In addition to accelerating the mixing of the solution and making the temperature and concentration uniform, stirring mainly promotes the mass ...

Embodiment approach 2

[0075] The second embodiment of the present application provides an electroforming liquid stirring device. The second embodiment is a further improvement of the first embodiment. The main improvement is that, in the second embodiment of the present application, see image 3 As shown, the liner 2 adopts a curved surface to further improve the convection effect of the electroforming liquid.

[0076] Wherein, the surface of the lining plate 2 perpendicular to the electroforming template is the first surface 21, and the surface opposite to the first surface 21 on the lining plate 2 is the second surface 22;

[0077] Several arc-shaped depressions 21a are formed on the first surface 21 .

[0078] Wherein, these depressions 21a can be randomly distributed on the first surface 21, and those skilled in the art can design the size of the depressions 21a according to factors such as the size of the electroforming tank and the density of the bath liquid.

[0079] The formed arc-shaped r...

Embodiment approach 3

[0081] The third embodiment of the present application provides an electroforming solution stirring device. The third embodiment is a further improvement of the second embodiment. The improvement is that in the third embodiment of the present application, see Figure 4 As shown, there are at least two depressions 21a, and the depressions 21a are arranged adjacent to each other so that the first surface 21 forms an approximately wavy curved surface.

[0082] When it is formed into a wavy curved surface, the tank liquids pushed by adjacent grooves can collide with each other to accelerate the mixing effect of the tank liquids.

Abstract

The invention provides metal mask electroforming equipment and an electroforming fluid stirring device. The electroforming fluid stirring device comprises a power source, an electroforming hanger anda lining plate; and the electroforming hanger is in transmission connection with the power source, can move in a reciprocating mode under driving of the power source and is used for hanging an electroforming formwork; and the lining plate is connected to the electroforming hanger and is generally perpendicular to the electroforming formwork. The area of pressure generated by the lining plate to electroforming fluid can be increased significantly in the moving process, and the stirring effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electroforming process equipment, in particular to an electroforming metal mask equipment and an electroforming liquid stirring device. Background technique [0002] The electroforming process is a process of accurately replicating a layer of metal film on the surface of a conductor by using the principle of electrochemical deposition. The film forming speed of the metal film is fast and its thickness can be controlled. It can be specifically described as: use the conductive template as the cathode, and the metal material as the anode, both of which are immersed in the electroforming solution. The anode metal material is the same as the metal ion in the electroforming solution. The metal ions in the cathode are reduced to metal and deposited on the surface of the template, while the anode metal is continuously transformed into ions and dissolved in the electroforming solution for replenishment, so that th...
