Method for manufacturing three-dimensional member via local etching and positioning tool

Abstract

The invention discloses a method for manufacturing a three-dimensional member via local etching and a positioning tool. The method comprises: firstly, manufacturing the position tool according to the shape of a to-be-etched three-dimensional member; secondly, plating the surface, needing to be etched, of the to-be-etched three-dimensional member with a layer of photosensitive ink via electrophoresis technique; removing the photosensitive ink on a part, needing to be etched, of the surface of the to-be-etched three-dimensional member via laser etching technique to expose the part needing to be etched; thirdly, positioning the to-be-etched three-dimensional member on the positioning tool, putting the positioning tool in an etching machine, and performing corrosion of a set depth with a pre-set etchant solution; and finally, performing film removing, cleaning, and drying of the etched three-dimensional member to obtain a finished three-dimensional member. According to the invention, the positioning tool for manufacturing the three-dimensional member via local etching can enable positioning of the to-be-etched three-dimensional member to be realized via forming a containing groove according to the shape (size) of the to-be-etched three-dimensional member. The cost is saved; the precision of the three-dimensional member is relatively high; and the specification and dimension are comparatively accurate.

Description

technical field [0001] The invention relates to the technical field of metal etching, in particular to a method for making three-dimensional parts by partial etching and a positioning jig for making three-dimensional parts by partial etching. Background technique [0002] Three-dimensional parts, also known as metal three-dimensional structural parts, are widely used in electronic products such as mobile phones. In the existing technology, when three-dimensional parts are produced, they are usually etched on the plane and then stamped. However, with the rapid development of electronic products, local Many three-dimensional parts stamped after etching fail to meet the precision requirements, and the pass rate is relatively low, resulting in waste of cost. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention proposes a method and a positioning jig for making three-dimensional parts by partial etching, which can ef...
