US 6,617,543 B1 · Method of making pattern for decorative piece

Abstract

A method of making patterns for decorative piece, comprising the steps of using a metal plate as the molding substrate for laser etching; placing the mold substrate under a laser etching device, and cutting the substrate into a recession of appropriate depth. Further, the height of the laser head of the laser etching device is lifted, and then the dispersion of laser beam can be accomplished by means of a reflective lens. In the meantime, the depth of etching is reduced progressively, and the etching area is expanded along the path of previously cut recession. The manufacturing is made by progressively lifting the laser emitting head according to the theory described above.

A method of making pattern for decorative piece, comprising the steps of:

using a metallic plate as the substrate for a mold;
etching the metallic plate with laser beam by incrementally moving the emitting position of the laser beam;
cutting the metallic plate to form an even recession with a specific depth, and the laser head being progressively lifted to a specific distance to expand the emitting area by the increased diameter of laser beam, and in the meantime, the cut depth being decreased progressively;
constantly lifting the position of the etching head and etching the same position on the metallic plate with a relatively shallower depth;
and the etching with expanded area etching a conical recession on the substrate of the mold;
and forming a plurality of small pins on a plastic material by plastic injection.

#The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

#Please refer to FIGS. 1a˜1d for a preferred embodiment of the present invention, which carves a substrate 10 of a mold by a laser beam 20, and such laser beam 20 is shifted with an increment of x to cut an evenly distributed recession 11 with a specific depth on the a surface first, and then progressively lifts the laser head 2 to a specific height in order to enlarge the diameter of the emitting area of the laser beam 20 by means of the reflection from a convex lens. At that time, the depth cut by the laser beam 20a is shallower than that produced by the laser beam 20. Same procedure is repeated to etch at the same position with progressively shallower layer 23. The laser head 20 is constantly lifted progressively and the depth of the emitting depth becomes shallower and the emitting area gets larger progressively to carve a small conical recession 12. After the small conical recession 12 with the precision of only 0.03˜0.07 mm is manufactured and formed by plastic injection of plastic material, small pins 24 (as shown in FIGS. 2˜4) are formed by formation of plastic material, and thus gives a soft touch feeling and friction when it is squeezed or touched.

#Therefore, method of making patterns for a decorative piece according to the present invention uses metallic plate for the substrate, and the following manufacture procedure is applied:
