Embodiment
Please refer to shown in Fig. 1, which show the multiple conductive base of the present invention, such as, the workpiece surface flow processs such as stainless steel, carbon steel, iron, aluminium, aluminum magnesium alloy; Wherein, remember that this step is not carried out in X surface; Till note ◎ represents this step, can be that finished product or selection continue next step again; Note V represents that this step is not also terminal, is not also finished product, also needs to carry out next step.
First, at conductive base, the workpiece surface such as such as stainless steel, carbon steel, iron, aluminium, aluminum magnesium alloy carry out first time surface pretreatment, and surface pretreatment refers to and first conductive substrate surface carried out to the process such as wire drawing, sandblasting or polished finish for the first time, determines according to customized requirement.Carry out wire drawing at surfaces of conductive substrates, can produce silking effect after electro coat, wire drawing is also not limited to straight line, and curve is also passable, and these can be determined according to customized requirement; Sandblasting, then can make follow-up surface-treated layer by during laser engraving process or more firm after processing procedure.
Subsequently, carry out second time surface pretreatment, second time surface pretreatment refers to and removes the processing procedures such as surperficial grease, washing, oven dry to the surface of above-mentioned workpiece, to remove the contamination particle on workpiece surface, as known techniques, its object is to avoid grease or impurity particle to affect the sticking power of electrophoretic paint layer.
Referring to the cross sectional representation of Fig. 2 A, and then, first time electro coat process is carried out, to plate one deck band color and to be different from the electrocoating paint 30 that conductive base 10 color thickness is about 15-30 μm.Aluminium or aluminum magnesium alloy can be selected before first time electro coat process, carry out anode oxidation coloration process (referring to Fig. 2 H), after above-mentioned aluminium, aluminum magnesium alloy carry out anode oxidation coloration process, can form aluminium oxide layers or the magnalium zone of oxidation 20 of a conduction rate variance, its thickness is about 2-10 μm; Now, during first time electro coat process, operating voltage when strengthen electrophoresis is about 20-50%, or reduces the distance of anode and negative electrode, to increase strength of electric field; Except accelerating electrocoating paint ionic transfer speed, reduce except the electro coat time when strength of electric field increases, strength of electric field increase also can penetrate aluminium oxide layers or the magnalium zone of oxidation of the surperficial weakly conducting rate of conductive base 10, and makes that follow-up to carry out electro coat process smooth.
Electrophoresis post-drying, just like known techniques.Subsequently, carry out primary laser engraving (being called for short radium carving) or brill carving, below according to one embodiment of the invention, radium carving process comprises the second pattern 42 forming the first pattern 41 and reduced thickness made a reservation for, as a result, as Fig. 2 B or Fig. 2 I(comprises anode oxidation coloration layer 20) shown in; First pattern 41 is worn by electrophoresis carved lacquerware corresponding in pattern, to expose conductive base 10 primary colors, or exposes anode oxidation coloration layer 20 as shown in figure 2i; Second 42, pattern is that electrocoating paint corresponding in pattern is not carved and worn, but it is thinning, such as, thickness be the electrocoating paint of 20 μm thinning be 5 μm-16 μm, in its thinning area, the same area thickness thinning is equal, different zones then thinning degree also can be different, such as, in the second pattern 42 ' subtract less.
In another embodiment (namely in the second embodiment), its thinning area is change, it is thinning that pattern thinning is not limited to " uniform thickness ", it also can be the forms such as " wedge shape " thinning, during radium carving, the mode of the oblique angle of radium-shine tilt is come thinning, the pattern carved out can be made so more to seem there is stereoscopic sensation, as shown in Figure 2 C.
When being plane for workpiece surface, such as, TV frame or hand set machine shell etc., the thickness of first electrocoating paint in each region of workpiece surface is roughly the same, therefore, controls electrocoating paint thickness local reduction relatively easy; When electrocoating paint local reduction instead of carving are worn, to therefore produce the visual effect of gradation, or three-dimensional pattern effect, its be due to electrocoating paint by local reduction time, the penetration coefficient of light is different from original thickness (non-carved region), or caused by zero thickness (electrocoating paint by all carving wears), particularly when the second pattern and the first pattern line have relation, the mesophyll position of such as blade is thinning area, and branch, stalk are then that carving is worn, shown in photo as shown in Figure 3A; Fig. 3 B is the schematic diagram in order to explanatory view 3A radium engraving patterns, and Fig. 3 C is then the photo being observed radium engraving patterns by side, obviously shows solid pattern.
Electrophoresis carved lacquerware is worn or thickness local reduction reaches with radium-shine power adjustment energy.In another embodiment, the change that also can control radium-shine pulse width is reached or is reached with the radium-shine cutter at pitch angle simultaneously; That is in the present invention, the radium-shine power of radium carving process is not fixing, or pulse width is not fixing, and it changes according to the position of radium engraving patterns, and this change is by formula planning control.
According to one more embodiment of the present invention, when first pattern is the frame of cataphoretic coating for the first time, please refer to Fig. 4, this can make only cataphoretic coating once, the color of more than two kinds can be produced, particularly, when above-mentioned it " wedge shape " is thinning after carrying out radium carving, it can show more color and stereoscopic sensation, and namely radium carving is different from least secondary electro coat layer of known techniques and secondary radium carving could produce two kinds of colors.
According to embodiments of the invention, electro coat adds the radium carving processing procedure of last time (also can repeatedly) reduced thickness, just can produce multicolour level effect, such as, radium is carved the second pattern 42 and is separately carried out the 3rd pattern 43 simultaneously, and namely the thinning degree of the 3rd pattern is different from the second pattern 42(and refers to shown in Fig. 2 A to Fig. 2 C).
Above-mentioned conductive base workpiece, namely can become finished product at first time radium after carving, except carbon steel, iron exception; Carbon steel or ferroelectric swimming coating formation first pattern (carving is worn) just do not have protective layer afterwards; therefore the worry of getting rusty is had; therefore for the conductive base of carbon steel or iron, must do second time electro coat or spray treatment again, other conductive base then alternative carries out second time electro coat.
According to one embodiment of the invention, second time electro coat or spray treatment before preferred embodiment be first carry out third time pre-treatment, the pre-treatment of third time be by aforementioned completed first time radium carving after workpiece carry out chemical roughen, epithelium process or physics alligatoring as sandblasting or the process of electricity slurry, the pre-treatment of third time can increase second time electro coat layer or the tack of sprayed coating.The pre-treatment of above-mentioned third time is not to destroy previous radium engraving patterns for principle, and therefore, during sandblasting, particle is fine, and the particle of such as sandblasting is the glass sand of No. 200, and pressure is between 2-4 kilogram; Chemical roughen refers to weak acid wiping or is stained with workpiece surface (iron or steel) or weak base wiping or is stained with workpiece (aluminium or aluminum magnesium alloy), or produces an epithelium on workpiece surface, to produce a very thin epithelium at workpiece surface; And electricity slurry directly bombards workpiece surface with the electricity produced under rare gas element high pressure slurry.
