- BEST MODE FOR CARRYING OUT THE INVENTION hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.
- the micropart is manufactured through the steps shown in FIGS. 1A to 1E.
- a laser direct drawing apparatus (not shown) is used to have a thickness of several tens of m, for example, 20 Atm to 5 Atm. Drill a hole corresponding to the cross section of the micro component in a 0-meter metal plate, and create a light-shielding mask 11 to block ultraviolet rays in areas other than those required. Since the light shielding mask 11 does not come into contact with the photocurable resin, any kind of metal can be used. However, the material of the light-shielding mask 11 is not limited to metal, and any material may be used as long as it does not transmit light and allows high-precision drilling.
- a light-shielding mask 11 is placed on the ultraviolet irradiation section 20.
- a cover glass 12 as a light transmitting plate is placed on the surface.
- the material of the power member on the light-shielding mask 11 is not limited to glass, but may be plastic as long as it transmits light.
- the photocurable resin 13 is placed on the cover glass 12, and the surface opposite to the surface in contact with the cover glass 12 is irradiated by the ultraviolet irradiation unit 20.
- UV light is irradiated from below the light-shielding mask 11 located at the bottom.
- the light to be applied is not limited to ultraviolet light, and light other than ultraviolet light can be used when the photocurable resin 13 is cured by light other than ultraviolet light.
- the target micropart 10 is obtained by irradiating ultraviolet rays again to completely cure.
- Figure 2 shows a cylindrical micropart that was actually manufactured using a light-shielding mask formed by processing a circle with a diameter of 500 m on a stainless steel plate with a thickness of 20 m.
- the UV irradiation time was 25 seconds.
- FIG. 2 by irradiating ultraviolet rays from below the two-dimensional light-shielding mask, three-dimensional micro parts can be manufactured.
- the vicinity of the front end located farthest from the light-shielding mask is thinner than the bottom surface. This is thought to be due to the properties of the photocurable resin when it is cured by ultraviolet rays. However, it is desirable to further improve the shape accuracy of the microparts actually used.
- the use of the top and side support structures can improve the shape accuracy, particularly in the height direction (ultraviolet ray transmission direction). That is, as shown in FIG. 3A, a side support member 14 is placed on the cover glass 12 to form a concave portion, and the concave portion is filled with the photocurable resin 13, and the concave portion is filled from above. The top support member 15 is placed so as to press the photocurable resin 13. Then, as shown in FIG. 3B, ultraviolet rays are irradiated from below the light-shielding mask 11 by the ultraviolet light irradiation unit 20.
- the height of the micro component necessarily coincides with the height of the side support member 14.
- the height of the side support member 14 is set lower than the highest point of the part to be cured by irradiating ultraviolet rays. There is a need.
- FIG. 4 shows the results when the light-shielding mask 11 was drilled so that a circular hole having a diameter of 100 m, 200 im, and 500 ⁇ was opened.
- the highest point of the cured portion also increases.
- the change in height was large when the ultraviolet irradiation time was 0 to 15 seconds, and almost no change was observed after 20 seconds or more. From this result, it is sufficient that the UV irradiation time is 20 seconds, and the height of the side support member 14 needs to be set lower than the height of the highest point when the UV light is irradiated for 20 seconds. I understand.
- the UV irradiation time was set to 20 seconds, and the height H of the hardened portion and the height of the point A when a cylindrical small part 10 was manufactured using a light-shielding mask 11 in which circles with different diameters were punched were manufactured.
- Table 1 below shows the relationship with h.
- FIGS. 6A and 6B show the microparts actually manufactured using the support structure.
- FIG. 6A shows the appearance of a cylindrical micropart having a diameter of 200 m
- FIG. 6B shows the appearance of a square prism-shaped micropart having a side of 100 zm. It is.
- the ultraviolet irradiation time was set to 20 seconds
- the height of the side surface member 14 was set to 600 ⁇ m.
- the use of the side support member 14 and the top support member 15 can improve the precision in the height and width directions of the micro component. .
- a metal plate is perforated into a shape corresponding to the cross section of the micro component to form a light-shielding mask 11, and the light-shielding mask 11 is formed.
- the cover glass 12 is placed on one surface, the photocurable resin 13 is placed on the cover glass 12, and then the cover glass 12 is placed on the other surface of the light-shielding mask 11.
- a micro component 10 can be manufactured with high precision by a simple method of irradiating the photocurable resin 13 with ultraviolet rays through the intermediary of the photocurable resin 13.
- a concave portion is formed on the cover glass 12 by the side support member 14, and the concave portion is filled with the photo-curable resin 13, and the photo-curable resin 13 is filled with the upper surface sabot member 15.
- the concave portion so as to press and irradiating ultraviolet rays from below the light-shielding mask 11, it is possible to manufacture a micropart 10 having higher shape accuracy.
- a lamination surface is not formed on the micro component and no step is caused by the lamination surface, so that the accuracy is improved. Small parts with high performance can be obtained.
