Abstract
The invention provides a laser micro-modeling method utilizing a mask. The laser micro-modeling method comprises the following steps: (1), covering a laser micro-modeling mask on the surface of a workpiece, wherein the laser micro-modeling mask is prepared by mixing a fusion-covering material and binder, the binder is an evaporable material, and does not react with the fusion-covering material; the laser micro-modeling mask comprises a mask substrate and mask micro pores, wherein the mask micro pores are formed on the mask substrate to form a dot matrix shape; (2), quickly scanning the area, which is covered with the laser micro-modeling mask, of the surface of the workpiece by continuous laser, wherein the fusion-covering and micro-modeling of the material surface are completed while the whole area covered by the laser micro-modeling mask is scanned by the laser. The laser surface fusion-covering processing and the laser surface micro-modeling processing are simultaneously realized by the laser micro-modeling method disclosed by the invention, so that the processing time is shortened, the energy is saved and the production efficiency is improved. The invention further provides a laser micro-modeling mask.
Description
Technical field
The present invention relates to the laser fine manufacture field, be specifically related to a kind of laser micro molding mask and utilize the laser micro molding process of mask.The present invention utilizes mask to cover surface of the work and with continuous laser rapid scanning mask overlay area, realizes the synchronous realization of laser melting coating and laser surface micro-moulding.
Background technology
Existing laser surface micro-moulding technology generally adopts pulse laser to cooperate workpiece movable to get pit array at surface of the work, not only speed is slow and the heat affected area is uneven for this processing mode, the degree of depth and the micromorphology of each pit have different simultaneously, simultaneously because many surface of the works need to prepare coating, tend to destroy coating behind the laser stereo lithography, need to again prepare coating, this duplication of labour is not only wasted resource and is also had a strong impact on working (machining) efficiency.
Summary of the invention
The object of the present invention is to provide a kind of laser micro molding process that utilizes mask, this laser micro molding process utilizes mask to cover then surface of the work reaches micro forming with continuous laser rapid scanning surface of the work purpose; It has solved that process velocity in the previous methods is slow, laser damage coating and the problem that repeats moulding.The present invention also provides a kind of laser micro molding mask simultaneously.
The present invention is achieved through the following technical solutions:
A kind of laser micro molding process that utilizes mask may further comprise the steps:
(1) covers the laser micro molding mask at surface of the work; Described laser micro molding mask is mixed by cladding material and binding agent, and described binding agent is easy evaporating materials, and does not react with cladding material; Described laser micro molding mask comprises mask substrate and mask micropore, and the mask micropore is arranged in the dot matrix shape in the mask substrate;
(2) with continuous laser rapid scanning is carried out in the zone that surface of the work covers the laser micro molding mask; Laser so that the cladding material cladding at surface of the work, and in ablate out nick hole of surface of the work; When the zone that the complete laser micro molding mask of laser scanning covers, cladding and micro forming work to material surface have then been finished simultaneously.
A kind of laser micro molding mask, described laser micro molding mask is mixed by cladding material and binding agent, and described binding agent is easy evaporating materials, and does not react with cladding material; Described laser micro molding mask comprises mask substrate and mask micropore, and the mask micropore is arranged in the dot matrix shape in the mask substrate.
The beneficial effect of the laser micro molding process of mask that utilizes of the present invention is:
1, laser micro molding process of the present invention has been realized cladding laser surfaces processing and laser surface micro-moulding processing simultaneously, has shortened process time, has saved energy, has improved production efficiency.
2, laser micro molding process of the present invention can adopt continuous laser that surface of the work is scanned by mask, has improved process velocity, and simultaneously also with the heat affected area homogenising, nick hole pattern also reaches unanimity.
3, laser micro molding process of the present invention, form different surface of the work nick hole arrays and only need change mask and not need to change the laser scanning routing sequence so that the laser scanning route becomes simply by the introducing of mask, has dwindled workload.

The specific embodiment
Following examples are used for illustrating the present invention, but are not restriction the present invention.Describe the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, laser micro molding mask of the present invention is comprised of mask substrate 1 and mask micropore 2, and mask micropore 2 is arranged in the dot matrix of definite shape in mask substrate 1.Described laser micro molding mask is mixed by cladding material and binding agent, and described binding agent is easy evaporating materials, and does not react with cladding material.
The laser micro molding process that utilizes mask of the present invention may further comprise the steps:
(1) as shown in Figure 3, laser micro molding mask 7 is covered workpiece 5 surfaces;
(2) carry out rapid scanning with continuous laser according to 6 pairs of laser micro molding mask 7 overlay areas of laser beam scan path, the result as shown in Figure 4 after the scanning;
The fuel factor of laser so that the Binder Composition in the laser micro molding mask 7 at first evaporate, then laser so that the cladding material cladding at surface of the work, workpiece 5 surfaces form one deck cladding layers 3;
Because the existence of mask micropore 2, when the mask micropore 2 of the inswept mask surface of laser, owing to do not have cladding material in the mask micropore 2, thereby so that laser directly acts on workpiece 5 surfaces, go out nick hole 4 at workpiece 5 ablated surfaces, so just finished simultaneously laser melting coating and laser micro molding work.
