Abstract
The invention relates to a photoinduction device of a nonplanar object, comprising a carrier, a sensor, a sphere light absorption shell, a light reflecting layer, a light receiver and a light emitter, wherein the sensor is arranged in a center hole of the carrier; the sphere light absorption shell is arranged at the upper end of the carrier; the light reflecting layer is coated on the inner surface of the sphere light absorption shell, and a transparent plate is arranged at the outer side of the sphere light absorption shell; the light receiver is fixedly arranged on the transparent plate and is superposed with the focal point of the inside curved face of the sphere light absorption shell; the light emitter is arranged at the outer side of the light receiver; and the light receiver and the light emitter are both connected with the sensor electrically. When the light emitted from the light emitter irradiates the nonplanar object, the light receiver certainly receives the light if only the light is reflected to the inside curved face of the sphere light absorption shell after reflection, thereby ensuring that the light receiver can sense the existence of the nonplanar object. The invention can effectively overcome the defects of the traditional object photoinduction device.
Description
Technical field:
The present invention relates to the photoinduction sensing device of object, relate in particular to the photoinduction sensing device of nonplanar object.
Background technology:
Reflective object light induction installation is commonly called as optoelectronic switch, it all has application in many automation equipments, the illumination that optical transmitting set from optoelectronic switch sends is mapped to after body surface, after object reflection, be irradiated to again the optical receiver of optoelectronic switch, make the existence of optoelectronic switch perception testee, then by optical sensor, to control system, send corresponding control signal.Existing optoelectronic switch is fine to having the perceptibility of planar object, and sensitivity is very high, and just not high for nonplanar object sensitivity, and existence that sometimes also can imperceptible object, sends wrong signal to automation equipment.According to the transport property of light, in conjunction with existing optoelectronic switch structural analysis, just can know the reason that produces above-mentioned defect, the optical receiving set of existing optoelectronic switch is one and accepts plane, optical transmitting set is positioned at the center that light is accepted plane, when illumination that optical transmitting set sends be mapped to have plane be detected on object time, light can be irradiated to after reflection light and accept in plane, by optical receiver perception, if when being detected object and being nonplanar object, light will change transmission path after reflection, reverberation just not necessarily can be irradiated to the light of optoelectronic switch and accept on face, reverberation can reflex to different directions with the size cases that is detected body surface radius of curvature, probably can not be by the perception of optical receiver institute, thereby the control system that makes automation equipment obtains wrong control signal, cause transfer matic to produce serious serious accident.
Summary of the invention:
In order to overcome existing reflective object light induction installation, can only respond to the shortcoming with planar object, the invention provides a kind of Photoinduction device of nonplanar object.
The technical solution adopted in the present invention is:
The Photoinduction device of nonplanar object of the present invention, it comprises carrier, transducer, sphere extinction shell, reflection layer, optical receiver and optical transmitting set, center at carrier is provided with centre bore, installation of sensors is in centre bore, and fixed by the stop screw of side, it is characterized in that: in the upper end of carrier, be provided with sphere shrinkage pool, sphere extinction shell is housed in sphere shrinkage pool, reflection layer is coated on the inner surface of sphere extinction shell, outside at sphere extinction shell is provided with transparent panel, transparent panel is fixed on sphere shrinkage pool suitable for reading of carrier upper end, and push down sphere extinction shell, optical receiver is fixedly mounted on transparent panel, this place overlaps with the focus of sphere extinction shell negative camber, optical transmitting set is arranged on the outside of optical receiver, optical transmitting set is all connected with sensor electrical with optical receiver.
Because the upper end at carrier is provided with sphere extinction shell, inner surface at sphere extinction shell scribbles reflection layer, optical receiver is arranged in the focus of negative camber of sphere extinction shell, when illumination that optical transmitting set sends is mapped on nonplanar object, light reflexes on the negative camber of sphere extinction shell after reflection, as long as reverberation shines on sphere extinction shell, reverberation must be irradiated to through the negative camber reflection layer reflection of sphere extinction shell the optical receiver being positioned in focus again, thereby guarantee that optical receiver can perceive the existence of nonplanar object, it can effectively overcome the deficiency that existing object light inductive sensory appts exists.
