Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a foldable anode shielding device for electroplating. Background Art

[0002] Electroplating is a process that uses the principle of electrolysis to cover a thin layer of metal on the surface of metal or other conductive materials. It is widely used in industrial production and daily life. During the electroplating process, when electroplating is performed on the surface of foils and plates, due to the uneven distribution of electric lines and edge effects, the electric lines at the edge of the anode are denser, and the current density in this area is relatively larger, which makes the surface plating amount of the foil and plate used as the cathode uneven during the electroplating process. Therefore, an anode shielding device is usually required to prevent oxides or other impurities on the surface of the anode from entering the plating solution and affecting the quality of electroplating. The anode shielding device is generally made of insulating material, metal material wrapped with insulating material, or replaceable metal material. Its shape and size match the anode, covering the surface of the anode or placed between the cathode and cathode at a certain distance from the anode surface to form a certain shielding width, thereby controlling the discharge area on the anode surface.

[0003] Existing anode shielding devices are usually fixed, that is, the shielding width is fixed and cannot be adjusted according to different electroplating conditions and requirements. This will lead to uneven edge electric line density during the electroplating process, thereby affecting the amount of electrodeposition in the cathode area and causing unevenness on the electroplated surface. At the same time, fixed anode shielding devices are not suitable for electroplating foils and plates with different widths, because the shielding width cannot be adjusted according to the width of the foil or plate, resulting in unsatisfactory shielding effect.

[0029] The shielding unit 3 includes a first shielding plate 31 and at least one second shielding plate 32. The width of the first shielding plate 31 can be 0.5CM, so that the adjustable shielding width of the first shielding plate 31 is 0-0.5CM. The width of the second shielding plate 32 can be 1CM, so that the adjustable shielding width of the second shielding plate 32 is 0-1CM. The first shielding plate 31 is arranged on one side of the fixed recovery plate 1; the second shielding plate 32 is arranged between the fixed recovery plate 1 and the first shielding plate 31; a positioning sliding device 2 is arranged between the fixed recovery plate 1 and the second shielding plate 32, between two adjacent second shielding plates 32, and between the second shielding plate 32 and the first shielding plate 31; two slide rails 21 are symmetrically arranged on the surface of the fixed recovery plate 1 and the surface of the second shielding plate 32; the slide rails 21 can be embedded, so that there is only a small gap between the two shielding plates to avoid the shaking of the shielding plates caused by the flow of the plating liquid in the gap; the bottom surface of the second shielding plate 32 and the bottom surface of the first shielding plate 31 are provided with pulleys 22, and the second shielding plate 32 and the first shielding plate 31 can be driven by the pulleys 22 to realize the movement of the second shielding plate 32 and the first shielding plate 31, thereby realizing the adjustment of the shielding width of the shielding unit 3. The first shielding plate 31, the plurality of second shielding plates 32 and the positioning sliding device 2 together form a foldable structure of the shielding unit 3, thereby realizing the foldability of the shielding device and reducing the space occupied.

[0030] The position and number of the shielding units 3 can be adjusted as needed to change the shielding width, so that the adjustment range of the shielding width is between 0CM and N (the number of second shielding plates 32) + 0.5CM; and the edge electric line density can be adjusted to change the corresponding cathode area electrodeposition amount, thereby improving the uniformity of the electrodeposition amount on the electroplated surface of the foil and plate, and foils and plates with different widths can be electroplated.

[0031] In some embodiments, at least four pulleys 22 are provided on the first shielding plate 31 and the second shielding plate 32.
