Light supplementing device with reflector

Abstract

The invention relates to a light supplementing device with a reflector. The light supplementing device comprises a carrier, a shell, a connector, the reflector, an annular light source and a CCD (charge coupled device). The shell is placed in the carrier; a shell hole is arranged on the shell, the connector is mounted on the shell, and a certain side surface of the connector can be seen via the shell hole; the annular light source is mounted on an annular light fixing plate, the CCD is mounted on a CCD fixing plate by a CCD adjusting plate, and the central axis of the annular light source is concentric with that of the CCD; and an adjusting screw seat is fixedly connected onto the CCD fixing plate, a fine adjustment knob penetrates through through holes on side surfaces of the adjusting screw seats to be screwed with the CCD adjusting plate. The reflector is mounted on the carrier and is positioned on the lower portion of the shell hole, and light of the annular light source is irradiated to the reflector and can transmit out from the shell hole after being reflected, so that relative positions of the contour of the shell hole and the connector can be shot by the CCD. The light is supplemented via the reflector, so that the CCD can shoot pictures clearly, and the light supplementing device brings convenience for detection and is simple in structure and principle.

Description

Technical field: [0001] The invention relates to a light supplementing device for a reflective sheet, which is used in the field of electronic products in a CCD vision system. Background technique: [0002] The CCD vision system is used to detect whether the relative position of two relative parts of a certain part of the product appearance is qualified. If it is not qualified, the CCD will calculate the relative movement distance required to reach the qualified position. The CCD is the same as the video camera, it needs to be illuminated by a light source when shooting. When shooting the outer surface of the product, it can be realized with a common light source, but to take an image of the inside of the shell hole of an electronic product, only a common light source is not enough , when using a common light source, the photographed effect is that the area along the outline of the shell hole is black, and the parts in the hole cannot be seen. Because the shell hole is small...

AI Technical Summary

Problems solved by technology

The CCD is the same as the video camera, it needs a light source to illuminate when shooting. When shooting the outer surface of the product, it can be realized with an ordinary light source, but to take an image in the hole of the electronic product shell, only the ordinary light source is not enough. , when using a common light source, the photographed effect is that the area along the outline of the shell hole is black, and the parts in the hole cannot be seen. Because the shell hole is small, the connector is also small, and inside the shell hole, the CCD only Relying on the direct ring light source, the outline of the connector cannot be photographed, so the relative position of the two components cannot be photographed, and the purpose of detection cannot be achieved.
