Reversed-type semi-transparent mirror reflector

Abstract

The invention discloses a reversed-type semi-transparent mirror reflector, which comprises an acryl plate, a plurality of circuit boards, a reflector plate and a semi-transparent mirror, wherein the acryl plate is a plate capable of dispersing light, a plurality of holding grooves are formed on one face of the acryl plate, a base is arranged at the bottom of each holding groove, the circuit boards are arranged in the bases in the holding grooves, and a plurality of light emitting modules are arranged on the surface of the circuit boards; and the reflector plate covers one opening face of the acryl plate, which is provided with the holding grooves, is used for reflecting light of the light emitting module, the semi-transparent mirror is combined on the other surface of the acryl plate, and the semi-transparent mirror has a semi-reflecting coating. The reversed-type semi-transparent mirror reflector disclosed by the invention can provide a uniform light sources and reflect images at the same time.

Description

【Technical field】 [0001] The present invention relates to a self-luminous reflector, in particular to a reverse semi-transparent reflector which utilizes an acrylic plate and a reflective sheet to reflect a light source so that the reflector can reflect an image and simultaneously provide a light source. 【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 Many inspection tasks that were performed manually in the past have also been replaced by automatic optical inspection equipment.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 optica...

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
