Light supplementing assembly, shooting assembly and laser engraving equipment

Abstract

The invention discloses a light supplementing assembly, a shooting assembly and laser engraving equipment, and belongs to the technical field of automation. The light supplementing assembly comprisesa first light source and a second light source, a first light beam emitted by the first light source is perpendicular to an imaging plane of a camera and can irradiate the bottom wall of a cambered surface groove of a product, and a second light beam emitted by the second light source and the first light beam emitted by the first light source intersect above the product and can irradiate the sidewall of the cambered surface groove of the product. The shooting assembly and the laser engraving equipment comprise the light supplementing assembly. According to the invention, effective light supplement can be carried out on products made of various high-reflectivity materials, and the shooting effect of the products is improved.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a supplementary light component, a photographing component and laser engraving equipment. Background technique [0002] Laser engraving refers to the use of laser (laser) beams to engrave permanent marks on the surface of a material or inside a transparent material. Due to the use of high-reflective materials (aluminum alloy, stainless steel, ceramics, etc.), the different surface colors of the products, and the curved surface of the laser engraved logo, it is more difficult to check the appearance quality of the logo, and the false detection rate increases. When the laser marking surface is made of highly reflective materials, the detection effect of the existing visual inspection system is poor. If the radian of the laser marking surface is increased, the detection effect of the existing visual detection system is even worse. The main reason is that the supplementary light c...

AI Technical Summary

Problems solved by technology

Due to the use of high-reflective materials (aluminum alloy, stainless steel, ceramics, etc.), the surface color of the product is different, and the laser engraved logo surface is a curved surface, etc., it is more difficult to check the appearance quality of the logo, and the false detection rate increases.

When the laser marking surface is made of highly reflective materials, the detection effect of the existing visual inspection system is poor. If the radian of the laser marking surface is increased, the detection effect of the existing visual detection system is even worse. The main reason is that the supplementary light component ( Ordinary light sources) have poor lighting effects and are prone to high reflection or dark spots, which makes it impossible for the camera components to obtain stable and non-reflective images

[0003] If the supplementary light components and shooting components are only suitable for the lighting and shooting requirements of products of one specification, it is necessary to purchase multiple specifications of supplementary light components and shooting components for lighting and shooting of products of corresponding specifications, resulting in High equipment purchase cost and high after-sales maintenance cost
