Description
Technical Field
The utility model belongs to the technical field of photoelectric switch, concretely relates to novel photoelectric switch.
Background
The photoelectric switch is a short-term photoelectric proximity switch, and detects the existence of an object by utilizing the shielding or reflection of the detected object to a light beam and switching on a circuit through a synchronous circuit. The object is not limited to metal, and all objects that reflect light (or block light) can be detected. The photoelectric switch converts the input current into an optical signal on the transmitter to be emitted, and the receiver detects the target object according to the intensity or the existence of the received light. A common photoelectric switch smoke alarm in a security system is frequently used in the industry for counting the movement times of a mechanical arm.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel photoelectric switch to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel photoelectric switch, includes the casing, light source transmitter is installed to the casing upper left side, and the reflector panel is installed to the casing under the light source transmitter, installs the reflector on the reflector panel, the casing mid-mounting has the light ring that corresponds with the reverberation of reflector, and the light ring is concentrated the light beam on light source receiver, and light source receiver has the detection circuitry ware through fiber connection.
Preferably, the light source emitter is internally provided with a light emitting diode.
Preferably, the reflector is inclined at an angle of 45 degrees.
Preferably, a circular opening matched with the reflector is formed in the shell right below the light source emitter.
The utility model discloses a technological effect and advantage: this novel photoelectric switch, structural assembly is reasonable, and the principle is simple, and equipment is small, can concentrate the light beam well for switching sensitivity is higher, and the response is faster.
Drawings
Fig. 1 is a schematic view of the main structure of the present invention.
In the figure: 1. a housing; 2. a light source emitter; 3. a light emitting diode; 4. a reflector; 5. a reflective mirror; 6. an aperture; 7. a light source receiver; 8. an optical fiber; 9. and a detection circuit device.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a as shown in fig. 1 a novel photoelectric switch, including casing 1, light source transmitter 2 is installed in 1 upper left side of casing, installs reflector panel 4 in casing 1 under light source transmitter 2, installs reflector 5 on the reflector panel 4, 1 mid-mounting of casing has the light ring 6 that corresponds with reflector 5's reverberation, bunches and concentrates the light source, reduces the emergence of light leak condition, and light ring 6 concentrates on light source receiver 7 with the light beam, and light source receiver 7 is connected with detection circuitry ware 9 through optic fibre 8.
Specifically, the light source emitter 2 is internally provided with a light emitting diode 3 for providing a light source for the photoelectric switch.
Specifically, the reflector 4 is inclined at an angle of 45 degrees, and reflects the light emitted from the diode.
Specifically, a circular opening matched with the reflector 5 is formed in the shell 1 right below the light source emitter 2, so that a light source can conveniently penetrate through the shell 1 to irradiate the reflector 5.
The working principle is as follows: this novel photoelectric switch, when using, 3 circular telegrams of emitting diode send the light source, then send light source receiver 7 with light transfer, and the light source is restrainted and is concentrated through the receipts of light ring 6 in this process for the luminous intensity is stronger more concentrated, then light source receiver 7 passes through optical fiber transmission with light signal and gives detection circuit ware 8, and detection circuit ware 8 carries out the opening and shutting of signal judgment control switch at last.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
