Detailed description of the invention
The term used in this specification and claims book or word, not limited interpretation is common or meaning in dictionary, and should from inventor in order to the invention of self is described with the method for the best, principle based on the concept suitably defining term is considered, is interpreted as meaning and the concept of technological thought according to the invention.
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is the sequence of steps figure of surface treatment method of the present invention.
First, surface treatment method of the present invention be can also be applied to complete plastic working and surface of base specification product on and formed technology, it is characterized in that, can also be applied to be suitable for used in the past all surface processing specification metal material on, other surface specifications can be manufactured.
Based on this, preferred embodiment is described.
First, perform shape procedure of processing to the metal material that can use with various object, it refers to such as use rolling to equip, and is cut by the metal material of multiple material and bends to the apperance having and expect as shown in Figure 2.Now, for shape procedure of processing as above, operation can be carried out in advance as mentioned above, also can carry out operation prior to mask portion described later strip step, as long as or the problem of solution blemish, also can carry out operation after end grinding steps.In addition, above-mentioned shape procedure of processing refers to comprise the plastic working of rolling and extrusion molding and die cast, is all contained in this by the article shaped of general multiple processing method manufacture.
Just, in the preferred embodiments of the present invention and accompanying drawing, for the ease of understanding, illustrate the metal material 10 under the state processing shape.
Therefore, for the exposing surface actuating surface procedure of processing of the metal material 10 under the state completing shape processing as mentioned above.For Surface Machining step now, brushing fine rule can be utilized to process, be with fine rule processing and the existing various method of surface finish such as attrition process or sand milling processing, except the processing of above-mentioned matt surface, the light processing that has based on polishing also can be contained in this.
Thus, as shown in Figure 3, for metal material 10, carrying out under the state of Surface Machining step for obtaining finished surface 11, masks is being performed to above-mentioned finished surface 11.Masks is now realized by the various methods as being coated with or electroplating usually, through the masks of various method as above, forms diaphragm to the finished surface of metal material.Herein, the mask portion generated by masks as above as shown in Figure 4, the thickness in its mask portion 12 is preferably in the scope of 3 μm ~ 45 μm, when the thickness in mask portion 12 is thin, in the grinding steps performed afterwards, mask portion 12 can occur peel off or the phenomenon of demoulding, this is because when thickness is blocked up, the laser lift-off step for the formation of pattern becomes difficulty or the phenomenon that periphery mask portion comes off etc. occurs.
Particularly, if form the mask portion 12 for the finished surface 11 of metal material 10 by method as above, then the mask portion 12 of the finished surface 11 surrounding metal material 10 is performed to the stripping of pattern form, as shown in Figure 5, aforementioned mask portion 12 should be removed with the shape identical with the decorative pattern that will be formed and pattern by laser lift-off step.
Namely, use the laser marking machine of general type, but when considering from a large amount of equipment benchmark, the primary condition of power 60 ~ 80, speed 300 ~ 500 is best, in condition setting as above, the important point is the damage preventing the finished surface 11 to metal material 10 caused by laser marking machine.This is because, such as in the stripping process in the mask portion based on laser marking machine, when producing damage to the finished surface 11 of the metal material 10 comprising mask portion 12, can produce for the finished surface 11 of the metal material 10 generated in above-mentioned Surface Machining step corrosion or generate the mark line etc. that caused by laser, desired result thing can not be obtained.
In addition, in masks as above, when forming mask portion 12 according to the method as being coated with or electroplating, although laser lift-off step as above is necessary, but when directly forming tool figuratum mask portion 12 by the etching based on dry film to the finished surface 11 of metal material 10, do not need laser lift-off step.
Because this is by printed patterns direct on dry film, the mode of the film of this part by etching except eliminating pattern is formed, therefore on the finished surface 11 of metal material 10, direct formation has the mask portion 12 of various pattern, thus does not need the extra strip step for mask portion 12.
By laser lift-off step as above or utilize the pattern of dry film to be formed, as shown in Figure 6, the finished surface 11 of metal material 10 can intactly expose.Now, for the floral designs between the stripping area applying laser marking machine, importantly between line, spacing (line shadow spacing) is no more than 0.35mm, this is because when spacing is more than 0.35mm, the removing in mask portion can be hindered, in grinding steps, produce the slag caused by the residue in mask portion, do not have the mask portion removed directly to cause the surface of metal material 10 bad.
Then, by process as above, when the finished surface 11 of metal material 10 is formed figuratum mask portion 12, grinding steps is performed for the finished surface 11 except aforementioned mask portion 12.Grinding steps now can be divided into the Ginding process of chemistry and the Ginding process of physics.
Namely, the Ginding process of chemistry refers to the processing being called electrolytic polishing, in general be the processing making the electric current of 12V ~ 15V flow through the phosphoric acid of 55 DEG C ~ 75 DEG C and sulfuric acid liquid to carry out, if carry out the grinding of chemistry as above, then as shown in Figure 7, only on the finished surface 11 of the metal material 10 exposed in the mask portion 12 except coating or plating etc., form the fine ground of chemistry, and respective face can be formed with the glassy surface 13 of light.
In addition, physical grinding is referred to as polishing usually, by encasing grinding material and High Rotation Speed with cloth, carries out fine ground to exposed finished surface, and corresponding exposed surface is had have light face.When carrying out chemical grinding as above or physical grinding, even if under the state that the finished surface 11 of metal material 10 is the glossy surface obtained in Surface Machining step, also mutually different glossy surfaces is formed due to the difference of the cutting degree on small surface, therefore visually there is distinctiveness, can think the glassy surface 13 that can be formed and have with the diverse aesthetic feeling of finished surface 11 before.
When terminating grinding steps as above, as shown in Figure 8, as long as perform the removing step for above-mentioned mask portion 12, use the general stripping remover used on metal at present also can guarantee not damage the clean face of metallic surface, therefore, in above-mentioned mask removing step, specific description is omitted due to not special place.Just in mask removing step, the main material used is equivalent to remover, nitromethane, carrene, toluene, acetone and their mixture.In addition, the mask portion 12 based on dry film is preferably NaOH.
Then, at the end of mask removing step as above, directly can use this, also can increase rear surface treatment step to apply to metal material 10 as required, when holding corrosion-prone material or color sensation or the outstanding not metal material of texture, when wanting color sensation or the texture forming expectation, in order to carry out the surface treatment of chromium plating or deposition or coating or anodic oxidation etc., and the product of various appropriate state can be manufactured.
Therefore, as shown in Figure 9, product as described below can be manufactured: be there is the finished surface 11 obtained by various surface treatment and the glassy surface 13 having light pattern carrying out Duplex treatment to its finished surface and obtain on a metal material 10.
Illustrated by material object as shown in Figures 10 and 11, can clearer and more definite as above metal material, in case of fig. 10, unglazed process has been carried out to finished surface 11, unglazed finished surface 11 is concatenated to form to the pattern of the glassy surface 13 of light, Figure 11 illustrates under having carried out to finished surface 11 state having light process, has been concatenated to form the state having the pattern of the glassy surface 13 of light with differential glossiness.
Therefore, the duplex surface processing method of metal material of the present invention, the surface state had with restriction and its material of material has nothing to do, reasonably can form the glossiness decorative pattern of tool colorful, attractive in appearance and touch sample, therefore, having noble and multifarious while, can produce in a large number and the economic profit that maximizes.
In this description as above, described embodiment and the structure shown in accompanying drawing are only a preferred embodiment of the present invention, do not limit all technological thoughts of the present invention, should be understood to various equipollent and variation that existence replaces these.
