Semi-lens type self-luminous reflecting mirror

Abstract

The invention discloses a semi-lens type self-luminous reflecting mirror, which comprises a metal back plate, a plurality of circuit boards, a diffusion plate and a semi-lens, wherein the metal back plate is a plate sheet provided with metal luster; a plurality of containing grooves are formed on one surface of the metal back plate; the bottom of each containing groove is provided with a base; the two sides of the base are respectively provided with a reflecting surface; the circuit boards are laid in the bases of the containing grooves; a plurality of light emitting components are arranged on the surfaces of the circuit boards; the diffusion plate is a plate sheet which is pervious to light but cannot be fully perspective; the back surface of the diffusion plate is stuck to the metal back plate; the back surface of the semi-lens is provided with a semi-light-reflecting coating which is stuck to the front surface of a diffusion layer. By adopting the semi-lens type self-luminous reflecting mirror disclosed by the invention, an even lighting source can be provided and images also can be reflected.

Description

【Technical field】 [0001] The present invention relates to a self-illuminating reflector, in particular to a semi-lens type self-illuminating reflector which utilizes a metal back plate to reflect a light source so that the front of the reflector can reflect images and simultaneously provide light from the back. 【Background technique】 [0002] With the miniaturization of products, the size of various parts is gradually reduced, and the inspection procedures and inspection equipment in the production process are also adjusted to the miniature size. Nowadays, the analytical ability of digital images has been greatly improved, and digital images taken with optical lenses combined with computer automatic inspection equipment are gradually becoming popular. Many inspection tasks that were performed manually in the past have also been replaced by automatic optical inspection equipment. [0003] Please refer to figure 1 As shown, it is a schematic configuration diagram of automatic...

Problems solved by technology

[0004] Although the existing technology can obtain multiple angle images of the object 1 to be measured at the same time, since the light source 3 and the reflector 31 are not at the same angle, shadows will be formed on the object 1 to be measured, resulting in misjudgment of the image comparison ; and because the light source 3 directly shoots into the lens of the camera 2, it is easy to form a halo and affect the image quality
