Although there is prior art first to carry out anode processing on metal chassis surface, then upper required color or pattern are adhered to print, but such a mode forms large-scale coating for metal is easy, therefore it is not easy to maintain metal surface gloss, and color or pattern appended by the printing easily comes off because abrasion resistance is relatively low.And the process adhered to printing for color and pattern is relatively complicated and be difficult accurate construction, and the printing colouring or pattern must largely be constructed, and be applied for the dress of small range, or a small amount of construction, it is not easy to carried out the conversion of flexibility and lacked change.The content of the invention

The problem of in view of the prior art, inventor appreciates that should have a kind of improved system and method, a kind of workpiece surface color processing method is designed for this, its step at least includes：Porous diaphragm is formed with anode processing in a workpiece surface；With the anode tracheid of the depth formation opening upwards in the hole；Then colorant is filled in the anode tracheid by the opening；It is forced into drying；Then the workpiece surface is immersed in a hole sealing agent, to complete to seal to the anode tracheid；Take out curable type after the workpiece drying for the diaphragm sealing of hole program for having completed surface.So as to although the present invention is same to carry out workpiece surface anode processing, more derivative following advantage：

1. it is rapidly completed figure, word, numeral or symbol. 2. figure, word, numeral or symbol is sealed in completely in anodic oxide coating.

3. without the unnecessary colorant of remaining, after the completion of coating, it is not required to remove unnecessary colorant again.

4. colorant usage amount is few, so can significantly shorten the dry time.

5. colorant is all filled to the tracheid of anodic oxide coating, it is to avoid the risk being stripped off when using.

6. make figure, word, numeral or symbol lines and color it is more careful with it is clear.

The present invention can fill colorant in the front or rear step of the anode tracheid in the opening, dyed for the workpiece, it must be influenceed with the part for making the anode tracheid not include in itself or by the dyeing, and make it that workpiece surface colour is presented more saturation and reaches more multicoloured change, and through filling colorant and the mutually auxiliary coloring of dyeing, anode tracheid is greatly decreased and omits coloring.Brief description of the drawings

Below by the auxiliary of schema, illustrate present disclosure, characteristic and embodiment, so that expensive examine is further understood by the present invention.

Refer to shown in Fig. 1, the present invention is on a kind of workpiece surface color processing method, and its step at least includes：1. porous diaphragm is formed with anode processing in a workpiece (preferably metal) surface；With the anode tracheid (1) (coordinating shown in Fig. 2) of the depth formation opening upwards in the hole；The previous operations of this program can be by workpiece surface cleaning and chemical polishing etc., to make workpiece more suitable for processing.Anode processing can produce tunic thickness about in 6 μ π ι to 15 m or so (being regardless of) porous oxide layer in workpiece surface, and this oxide layer is referred to as anode epithelium, because the surface formed is porous property, with outstanding permeability.

2. from opening filling colorant (2) in the anode tracheid (1) (with Fig. 2 shown in)； It is worth mentioning that the filling of the colorant (2) of the present invention is scattered in the profile selected from one of pattern, word, symbol, digital group.And the colorant (2) can be selected from organic toner or non-organic colorant according to environmental protection, characteristic.And the colorant (2) can also be selected from one below by the present invention according to needed for processing：Photosensitive colorant, UV colorants, environment-friendly ink, fluorescence colorant, discoloration colorant, false proof colorant, metal toner, electronics colorant and conductive colorant.

And be more precisely to fill, filling mode of the invention more can be with needle injection for it.

3. it is forced into drying；The dry time can be 0.1 second to a few hours.Or give baking box or UV (ultraviolets）Irradiation.

4. the workpiece surface is immersed in a hole sealing agent, to complete to seal to the anode tracheid (1) (coordinating shown in Fig. 2)；Curable type after 5. the workpiece component for taking out the diaphragm sealing of hole program for having completed surface is dried.

Refer to shown in Fig. 3, the present invention is when progress to opening fill color material (2) in the anode tracheid (1) its " preceding ", first the workpiece can be dyed, form dye layer (A), due to dyeing course so that the other part of the anode tracheid (1), because the colorant of dyeing, i.e. (color is preferably homochromy with the filling colorant (2) for dye layer (A) and the color that is contaminted, can also be not homochromy), it is diacritical use to be showed in embodiment with different lines, it is only and non-display homochromy or not homochromy, and the part that the anode tracheid (1) is not included must be dyed by this, and to opening fill color material (2) after the anode tracheid (1), the color formation colorant of one-piece machine member is uniform, fully.Although also, the dyeing, i.e. dye layer (A) a part of may first penetrate into the anode tracheid (1), not influenceing the filling of colorant (2) afterwards of the anode tracheid (1) so.
