Description
Technical field: the invention belongs to optoelectronic switch, particularly have the optoelectronic switch of self-cleaning function in a kind of electrical automation system that is used in factory.
Background technology: in the electrical automation system of factory, in order to satisfy the technological requirement of production line, realize repetition, purpose continuous, that automatically produce, usually adopt various forms of transducers, temperature, pressure, position signals are converted to the signal of electricity, realize the automatic operation of production line by Programmable Logic Controller; Optoelectronic switch is exactly a kind of photoelectric sensor of generally using on production line, optoelectronic switch is by irradiation, reflection and the reception of infrared light beam, the position signalling that receives is converted to the signal of telecommunication, then after processing through Programmable Logic Controller, production equipment is moved automatically according to the requirement of technique; The application of optoelectronic switch is controlled the automation of production process and is become simple, accurate, reliable.But transmit and receive the surface of illumination beam on long playing optoelectronic switch, particularly be used in the surface that transmits and receives illumination beam on the optoelectronic switch on the more production line of dust and fiber and will inevitably accumulate one deck dust, the dust of accumulation can stop and affect transmitting and receiving of light beam and make optoelectronic switch generation misoperation, directly affect the result of use of optoelectronic switch, even caused the stop work and production of production line.
Prior art document 1CN201608696U discloses a kind of waterproof photoelectric switch, " be achieved by the following technical solution: waterproof photoelectric switch; described luminous tube, light-receiving tube be the connection line plate respectively; connecting plug, lid, printing opacity box, fluid sealant, resistance are linked and packed by scolding tin; metal cap is controlled light path; fluid sealant is sealed in electronic devices and components in the printing opacity plastic box, thereby reaches the control purpose of water-tight.”
The disclosed waterproof photoelectric switch of prior art document 1 exists following defective and deficiency in actual use:
1, easily accumulating dust because of the surface of optoelectronic switch reception illumination beam makes optoelectronic switch produce misoperation.Although adopt fluid sealant electronic devices and components to be sealed in the purpose that has reached water-tight in the printing opacity plastic box, but do not play dustproof effect on the surface of optoelectronic switch reception illumination beam, on the contrary because illumination beam must first pass through plastic cement printing opacity box, control light path through metal cap again, reduced on the one hand acting on the luminous flux that optoelectronic switch receives the surface of illumination beam, thereby must improve the intensity of illumination beam; Be more prone on the other hand make optoelectronic switch produce misoperation because of the surface accumulation dust of optoelectronic switch reception illumination beam, directly affected the result of use of optoelectronic switch.
2, long-play can cause the optoelectronic switch that is sealed in the printing opacity plastic box because dispelling the heat reduction of service life.Fluid sealant is sealed in electronic devices and components when reaching the water-tight purpose in the printing opacity plastic box, and circuit board, components and parts that the inevitable outcome of generation is sealed in the printing opacity plastic box are subjected to heat ageing, have shortened the useful life of optoelectronic switch.
This shows, study and design and a kind ofly can reach self-cleaning effect in the uninterrupted dedusting of when operation, thereby and can also to play the optoelectronic switch with self-cleaning function that radiating effect increases the service life to optoelectronic switch be necessary.
Summary of the invention: the objective of the invention is to overcome the deficiencies in the prior art, study and design and a kind ofly can reach self-cleaning effect in the uninterrupted dedusting of when operation, thereby and can also play the optoelectronic switch with self-cleaning function that radiating effect increases the service life to optoelectronic switch.
Goal of the invention of the present invention is achieved by the following technical solution:
A kind of optoelectronic switch with self-cleaning function, comprise photo-electric conversion element, the mounting bracket that is used for the fixed light electric transition element, be fixed in the mounting bracket other end and be electrically connected in the circuit board of photo-electric conversion element, be used for mounting bracket and cover and close in the switch housing of photo-electric conversion element, circuit board periphery, it is characterized in that also being designed with the mini-fan that is fixed on the interior mounting bracket of switch housing and is positioned at the photo-electric conversion element rear.
One end of described switch housing offers the window for the surface that transmits and receives illumination beam of photo-electric conversion element; The other end of described switch housing is designed with the binding post that is electrically connected in circuit board; The bottom design of described switch housing is useful on and coordinates the movable bearing support that transmits and receives the surface that transmits and receives illumination beam illumination beam, the accurate adjustment photo-electric conversion element and window direction.
Described mini-fan is electrically connected in circuit board, and preferably adopts minitype axial flow fan.Described movable bearing support is selected and can rotate 360 °, while 180 ° of universal rotating stands of rotation in vertical plane in horizontal plane.
The optoelectronic switch with self-cleaning function that the invention process obtains has compared with prior art shown following beneficial effect:
When 1, having operation, uninterrupted dedusting reaches self-cleaning effect, thereby the surface accumulation dust of having avoided transmitting and receiving illumination beam because of optoelectronic switch makes optoelectronic switch produce misoperation.The optoelectronic switch with self-cleaning function that the invention process obtains, be arranged on the relevant position of production line during use, when switching on power optoelectronic switch work operation, because mini-fan is electrically connected in circuit board, and the supply voltage of mini-fan is identical with the supply voltage of optoelectronic switch, so the mini-fan operation of also working simultaneously; And be arranged on the rear of optoelectronic switch photo-electric conversion element due to mini-fan, the blast that minitype axial flow fan produces, with dust or the fiber in surperficial the place ahead that transmits and receives illumination beam of photo-electric conversion element, the window that offers from an end of shell blows open; Owing to being to work simultaneously with optoelectronic switch, continuous blast makes dust can not rest on the surface that transmits and receives illumination beam of optoelectronic switch again, thereby reaches the effect of automated cleaning.And the disclosed waterproof photoelectric switch of prior art document 1 does not possess this kind function, and the surface accumulation dust that also just can't avoid receiving illumination beam because of optoelectronic switch makes optoelectronic switch produce the defective of misoperation.
3, can coordinate the irradiating angle of the infrared beam that optoelectronic switch transmits and receives to be adjusted to the optimum reception angle, thereby obtain desirable optoelectronic induction sensitivity.The outer casing bottom of the optoelectronic switch with self-cleaning function that obtains due to the invention process is designed with movable bearing support, and in implementing, movable bearing support has been selected the universal rotational bearing that can rotate 180 ° of rotations in 360 °, vertical plane in horizontal plane, therefore compare with the optoelectronic switch of prior art, the irradiating angle that can coordinate easily the infrared beam that optoelectronic switch transmits and receives, the scope of 180 ° in can tune to optimum reception angle in 360 °, vertical plane by movable bearing support in horizontal plane, thereby obtain desirable optoelectronic induction sensitivity.
