Description

Ring formula scanner laser light curtain detection device

Technical Field

The utility model relates to a laser light curtain detection device, concretely relates to through LD emission point light source laser, convert into line source and PD by pendulous device and receive object reflected light signal, accomplish the laser light curtain detection device that the object is in detection area.

Background

There are two main ways that objects commonly used in the market pass through the detection area: one is that a light-emitting device is arranged at one side of a detected area, a light source receiving device is arranged at the other side of the detected area, when an object is positioned in the detected area, light is blocked, and a detector sends out a corresponding signal; when the mode is used for detecting one area, a plurality of pairs of light source transmitters and receivers need to be installed, the size of a detected object is determined by the installation density of the light source transmitters and the receivers, the higher the detection density is, the higher the cost is, and the greater the installation difficulty is. The second is by using a single-point return light detection sensor, which has both light source emitting and receiving means, and therefore only needs to be installed on one side of the inspected area; the disadvantage is that the size of the detected object is determined by the installation density, and the higher the detection density is, the higher the cost is.
