Acryl backplate type illuminating reflector

Abstract

The invention discloses an acryl backplate type illuminating reflector, which comprises a metal backplate, a plurality of circuit boards, a diffusion plate and a semi-transparent lens, wherein the acryl backplate is a plate capable of diffusing light, a plurality of holding grooves are formed on one surface of the acryl plate, a base is arranged at the bottom of each holding groove, and a reflection surface is formed on the back face of the acryl backplate; the circuit boards are arranged in the bases in the holding grooves, and a plurality of light emitting modules are arranged on the surfaces of the circuit boards; the diffusion plate is a plate which is transparent, but cannot be perspective completely, and the back face of the diffusion plate is attached to the acryl backplate; and the back face of the semi-transparent mirror is provided with a semi-reflection coating, and the semi-reflective coating is attached to the front surface of the diffusion layer. The semi-transparent mirror type self-lighting reflector disclosed by the invention is capable of providing a uniform lighting source and reflecting an image at the same time.

Description

【Technical field】 [0001] The present invention relates to a self-illuminating reflector, in particular to an acrylic backplate illuminating reflector which utilizes an acrylic backplate 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 Many inspection tasks that were performed manually in the past have also been replaced by automatic optical inspection equipment.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 automati...

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
