Embodiment Construction

[0019] The specific implementation manner of the present invention will be described in detail below.

[0020] One embodiment of the preparation method of the elevator button is: first electroplate a layer of electroplating layer 3 on the stainless steel button 1, and the electroplating layer is copper layer, nickel layer, and chromium layer successively from the base material layer, wherein: the thickness of the copper layer is about 20 μm , the thickness of the nickel layer is about 10 μm, and the thickness of the chromium layer is 0.2 μm-1 μm; after the laser beam emitted by the YAG laser is focused, the copper layer, nickel layer and chromium layer of the high-temperature high-temperature electroplating layer generated in the spot area are vaporized, and the stainless steel The surface is partially oxidized, resulting in a dark colored oxide layer. The laser beam emitted by the YAG laser is focused to produce a spot of about 0.05mm, and the main output laser mode is TEM 0...

Abstract

This invention is an elevator button and its production method. The button is a stainless steel part with at least one layer of electroplated coating and letter and / or figure on it. During production, first make a stainless steel part, then electroplated coating at least one time, then cutting the letter and / or figure on the button through a laser. The electroplated coating is chromic and / or copper and / or nickel multi layers or single layer.

Description

technical field [0001] The invention relates to an elevator button and a preparation method thereof, belonging to elevator parts and laser processing. Background technique [0002] At present, there are many methods for processing indicating characters and patterns on the surface of elevator buttons, such as screen printing, transfer printing, etching, etc., but these processing methods generally have limitations, for example: because elevator panels and buttons mostly use Metal materials, through silk screen printing and transfer printing on metal materials, the bonding force is not enough. If silk-screened floors or door opening and closing characters are used on the metal button surface, the characters will fade or be wiped off after a short period of time. If the method of etching characters is adopted, compared with the above method, although the use time is long, the preparation time is also long due to the need to chemically etch the characters, and the edges of the ...
