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.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.
The utility model provides a ring formula scanner laser light curtain detection device, includes laser production and check out test set 1 and frame equipment 2, frame equipment 2 is the carrier that laser produced and check out test set 1, laser production and check out test set 1 are including analytic module 3, LD module 4, PD module 5, mechanical pendulous device 6 and LED pilot lamp 7, 6 fixed surface of mechanical pendulous device is connected with the reflector, LD module 4 produces pointolite laser and passes through the reflector and form line source signal, the received optical signal conversion of PD module 5 is the signal of telecommunication, the output and the analytic module 3 of PD module 5 are connected, analytic module 3 electric connection LED pilot lamp 7. The laser generating and detecting device 1 is installed at any one of the four corners of the frame device 2. The LED indicator light 7 is a three-color indicator light.
The working principle is as follows: an LD module 4 in the laser generating and detecting device 1 is responsible for emitting point light source laser and irradiates a reflector of a mechanical swing device 6 to form a line light source, so that a detected area is scanned by the line light source, a PD module 5 receives optical signals reflected by an object and converts the optical signals into electric signals to be transmitted to an analysis module 3, the analysis module 3 analyzes waveform data of the electric signals and judges whether the object blocks light, and an LED indicator light 7 is controlled to give a signal to a user or output a signal to inform other systems; and finishing the detection of the light curtain object.
