Embodiment 1

[0047] Example 1: Plating a 100mm*100mm zinc oxide film layer

[0048] Spread the zinc powder evenly on the stainless steel plate and compact it to a thickness of 1mm, and then place a glass plate with a thickness of 3mm on it, keeping the upper surface of the powder layer and the focus of the scanning galvanometer in the same plane. Edit the black fill bitmap with the actual size of 100*100mm in the computer software that controls the laser output, and set the processing parameters as power 10W, frequency 80KHZ, scanning interval 0.1mm, scanning speed 400mm / s. Turn on the laser to make the laser scan according to the set processing parameters. After scanning, use a blower to blow off the powder that has not been irradiated by the laser and adhere to the glass plate and clean it with alcohol. A low-thickness, opaque zinc oxide film can be obtained on the surface of the glass substrate.

Embodiment 2

[0049]Example 2: Making exquisite patterns

[0050] Spread the zinc powder evenly on the stainless steel plate and compact it to a thickness of 1mm, and then place a glass plate with a thickness of 3mm on it, keeping the upper surface of the powder layer and the focus of the scanning galvanometer in the same plane. Edit the bitmap of the snowflake shape in the computer software that controls the laser output, and set the processing parameters as power 10W, frequency 80KHZ, scanning interval 0.1mm, and scanning speed 400mm / s. Turn on the laser to scan the laser according to the set processing parameters. After scanning, use a hair dryer to blow off the powder that has not been irradiated by the laser and adhere to the glass plate and rinse with water to obtain a clear and beautiful snowflake pattern on the surface of the glass substrate.

Embodiment 3

[0051] Example 3: Laser wiring

[0052] Spread the zinc powder evenly on the stainless steel plate and compact it to a thickness of 1mm, and then place a glass plate with a thickness of 3mm on it, keeping the upper surface of the powder layer and the focus of the scanning galvanometer in the same plane. Edit the vector diagram of the thin line shape in the computer software that controls the laser output, and set the processing parameters as power 10W, frequency 80KHZ, and scanning speed 500mm / s. Turn on the laser to scan the laser according to the set processing parameters. After scanning, use a blower to blow off the powder that has not been irradiated by the laser and adhere to the glass plate and rinse with water. Then, fine lines with a line width of micrometers can be obtained on the surface of the glass substrate.

Abstract

The invention discloses a laser coating device and a method based on a transparent material, belonging to the field of micro-machining. The device comprises a computer, a laser which is connected with the computer, a laser control system which is installed on the laser, a workstation, a transparent material plate, a target and a flat plate, wherein the laser is connected with the computer, the workstation is arranged below the laser control system, and the transparent material, the target and the flat plate are arranged on the workstation from top to bottom in sequence. When in coating, the target is arranged at the lower surface of the transparent material plate, the laser penetrates the transparent material from the upper surface and then illuminates on the target, and then the target is heated, melted and sputtered onto a close transparent substrate, later high calorie leads the transparent substrate to generate micro-melting, and thus causing a coating layer to be formed on the transparent material. The device has the advantages of simpleness, low cost, high precision and good controllability, and can coat a film with micron-level or nano-level thickness on the surface of the transparent material, wherein the film has good edge sharpness and the shape of the film can be controlled by the computer output.

Description

Technical field [0001] The invention relates to a laser coating device and method based on a transparent material. The method can coat a film with a controllable thickness on the surface of the transparent material, and belongs to the field of microprocessing. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. During electroplating, the plated metal is used as an anode, which is oxidized into cations and enters the electroplating solution; the metal product to be plated is used as a cathode, and the cations of the plated metal are reduced on the metal surface to form a plating layer. The purpose of electroplating is to plate a metal coating on the substrate to change the surface properties or size of the substrate. Electroplating can enhance the corrosion resistance of metals (corrosion-resistant metals are mostly used for coating metals), increase hard...
