It is to be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but on the contrary, is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

1 and 2, an apparatus 100 for anodizing a metal according to the present invention includes at least one member selected from the group consisting of magnesium (Mg), zinc (Zn), titanium (Ti), tantalum (Ta), hafnium Hf), niobium (Nb), and the like.

The metal anodizing apparatus 100 can be used to form an oxide film on the surface of most of the substrate 1, but is particularly useful for forming an oxide film by massively anodizing a substrate which is impossible to mount or is small in size A positive electrode power supply member 120 provided in an electrolytic space 112 of the electrolytic bath 110 to supply a positive power to the electrolytic bath 110, an electrolytic bath 112 filled with an electrolytic solution, A plurality of through holes 131a (131a) are formed on the surface of a body (131), which is detachably installed in the electrolytic space (112) of the electrolyzer (110) and on which a housing space (132) And an inner tube 130 receiving the positive (+) power from the positive power supply member 120.

Hereinafter, the constitution of each part of the present invention will be described in detail.

The electrolytic bath 110 is formed with an electrolytic space 112 filled with an electrolytic solution, and is provided with a negative electrode terminal 114 to which a negative (-) power source is supplied.

At this time, the electrolytic bath 110 has an opening at its upper part to move the inner cylinder 130 filled with the object 1 required to form an oxide film into the electrolytic space 112, So that the filled inner cylinder 130 is taken out of the electrolytic space 112 to the outside.

In addition, the electrolytic bath 110 may have various shapes such as a rectangular parallelepiped having an open top as a whole, a cube, and the like.

A discharge hole 113 is formed in the bottom of the electrolytic space 112 of the electrolytic cell 110 so that the electrolytic solution can move. A cathode power supply member 130 for supplying the anode power is provided in the discharge hole 113 do.

The anode power supply member 120 is made of a metal material to finish the exhaust hole 113 and supports the inner cylinder 130 at the upper center of the body 121 connected to the anode terminal 129, A connection protrusion 122 for supplying a positive (+) power source is formed, and an inlet hole 121a through which the electrolytic solution in the electrolytic space 112 flows is formed on the surface of the body 121, A discharge port 124 for discharging the electrolyte solution flowing through the inflow hole 121a is formed.

In this case, when the body 121 of the anode power supply member 120 is directly installed in the discharge hole 113 of the electrolyzer 110, there is a possibility of electrical short-circuiting. Therefore, A block 115 is mounted and supports the body 121 to the insulating block 115 to prevent direct electrical connection between the anode power supply member 120 and the electrolytic bath 110.

The inner tube 130 is provided in the electrolytic space 112 of the electrolyzer 110 and is filled with the body 1 and includes a body 131 on which an accommodation space 132 for accommodating the object 1 is formed A plurality of through holes 131a through which an electrolytic solution can move is formed on the surface of the electrode assembly 130, and openings are formed in the open top.

The body 131 of the inner tube 130 may be formed in a variety of baskets such as a cylinder, a cube, a rectangular parallelepiped, an ellipse and the like with an open top. The body 131 is made of a conductive metal material So that the electrolytic solution can be freely moved.

The inner tube 130 is provided at the upper portion of the body 131 with a lid 136 which can be opened and closed to prevent the inner body 130 from being separated from the inner tube 130 when the inner tube 130 is moved. The lid 136 is made of the same metal as the inner cylinder 130 and has a through hole 136a to allow the electrolyte to move smoothly.

The upper end of the inner tube 130 can be lifted up with a crane or the like so that the inner tube 130 can be inserted into or withdrawn from the electrolytic bath 110. A protrusion groove 139 is formed in a lower portion of the inner tube 130 to allow connection protrusions 122 formed at the center of the body 121 of the anode power supply member 120 to be connected.

When the inner tube 130 is installed in the electrolytic space 112 of the electrolyzer 110, the protrusion groove 139 of the inner tube 130 is connected to the connection protrusion of the anode power supply member 120, An anode power source is connected to the inner tube 130 as a whole to perform an anodizing process to form an oxide film on the surface of the substrate 1.

In this case, the inner tube 130 can be manufactured in a different size. In this case, when the inner tube 130 is manufactured to have a large size, the oxide film formation efficiency may be lowered in the case of the intermediate body 1 far from the inner tube 130 . In order to solve this problem, an electrode rod 137 protrudes upwardly in the receiving space 132 of the inner tube 130.

The electrode rod 137 may be provided with a plurality of spaced apart vertically upward spaces in the receiving space 132 of the inner tube 130. As shown in FIG. 3, if the distance between the electrode rods is narrow when the plurality of electrode rods 137 are arranged, a sufficient positive (+) power source can be smoothly supplied to the object to enhance anodizing efficiency. However, It is preferable to maintain the spacing of the electrode rod 137 appropriately according to the size of the object.

A cooling line 140 is connected to an outlet 124 formed in the lower portion of the body 121 of the anode power supply member 120 to cool the discharged electrolyte and re-supply the electrolytic solution to the electrolyzer 110. Generally, the electrolytic solution is heated to a high temperature during the anodizing process. If the electrolytic solution is not cooled, it is difficult to form an oxide film of desired quality by discoloring or decolorizing the oxide film, so that the electrolytic solution is cooled and circulated to solve it.

The cooling line 140 includes a recovery pipe 141 for guiding the electrolytic solution discharged through the discharge port 124 to the electrolytic bath 110 and an electrolytic solution circulating the electrolytic solution through the recovery pipe 141, And a cooler 143 for cooling the electrolytic solution forcedly circulated through the pump 142. The coolant circulates through the pump 142, In this case, the cooler 144 may use a known cooling device that circulates refrigerant to heat-exchange with the electrolyte to cool the electrolyte.

As shown in FIG. 4, a filter 144 may be further provided to remove impurities of the electrolyte discharged through the discharge port 124 and recovered in the recovery pipe 141. That is, the electrolytic solution circulating through the recovery pipe 141 is recirculated to the inside of the electrolytic cell through the filter 144, the pump 142, and the cooler 143. The return pipe 141 is provided with an on-off valve 145 so that the on-off valve 145 can be circulated according to the operation of the on-off valve 145. In this case, the filter 144 may use a known filter having a nonwoven fabric therein.

A drain pipe 147 having a drain valve 146 is connected to one side of the recovery pipe 141 to discharge the electrolytic solution through the operation of the drain valve 146 to control the level of the electrolytic solution filled in the electrolytic bath 110 Can be adjusted.

Further, a cooling coil 150 through which the cooling water circulates along the inner circumferential surface of the electrolytic bath 110 is further disposed to circulate the cooling water, thereby further improving the cooling efficiency. In this case, it is natural that the cooling water has piping and a pump for cooling water circulation separately.

Of course, it is natural that a separate control panel (not shown) is provided for a series of controls such as the input of the positive and negative electrode power supplies and the driving of the pump 142.

Hereinafter, an operation example of an apparatus for anodizing metals according to the present invention will be described with reference to FIGS. 1 to 4. FIG.

First of all, the object 1 of various forms, especially impossible to be fixed or small in size, is filled in the receiving space 132 of the inner tube 130 separated from the electrolytic bath 110, and then the object 1 is covered with the lid 136, Thereby preventing the object of the image pickup device from being detached.

The hook portion 138 provided at the upper portion of the inner tube 130 is lifted up and attached to the electrolytic space 112 of the electrolytic bath 110 after washing to remove grease, foreign substances and the like on the surface of the substrate 1. In this case, since the weight of the inner cylinder filled with the object 1 is heavy, the hook is hooked on the hook of the crane so as to move while being lifted up and attached to the electrolytic space 112 of the electrolyzer 110.

The connection protrusion 122 of the anode power supply member 120 is connected to the protrusion groove 139 of the inner tube 130 when the inner tube 130 is attached to the electrolytic bath 110.

When the positive electrode power source and the negative electrode power source are supplied to the positive electrode power supply member 120 and the electrolytic cell 110 or the negative electrode terminal under the control of the control panel in this state, the positive electrode power source is charged into the inner cylinder 130, An oxide film is formed on the surface of the substrate 1.

The electrolytic solution is circulated through the discharge port 124 through the inner cylinder 130 while being circulated by the pump 142 while being cooled by the cooler 143 while performing the anodizing treatment of the substrate 1, Lt; / RTI >

Through the above process, the coated object 1 having an oxide coating is washed and washed repeatedly several times, and if necessary, additional steps such as sealing and washing are performed, followed by drying and the like. Of course, such a series of subsequent processes can use automated facilities.
