Introduce operation principle of the present invention and preferred embodiment below
The present invention is a kind of light-focusing type photoelectric switch trigger mechanism that is applicable to intelligent automatic screw detection machine, spiral shellSilk travels forward along line slideway, when screw process optoelectronic switch is (by transmitter, receiver and detection electricityRoad composition) time, screw will block light path, and receiver cannot receive optical signal, and (this process is and triggeredJourney), PLC controller after receiving triggering signal is taken pictures drives camera. Thereby realize screw and advance to certain, will trigger optoelectronic switch, meanwhile, PLC controller will drive after receiving triggering signal when one the positionCamera is taken pictures.
Beneficial effect:
Adopt light-focusing type optoelectronic switch, optically focused precision can reach 0.1mm, can be applied in line slideway machineOn the detection machine of structure or index dial mechanism, and can realize precisely triggering one to one of multiple primary screws.
Be applied to light-focusing type optoelectronic switch as trigger mechanism on intelligent automatic screw detection machine, realize multiplePrecisely triggering one to one of primary screw, both can be used on the detection machine of guiding rail mechanism, also can be used on calibrationOn the detection machine of disc mechanism.
Intelligence automatic screw detects machine, and by camera 5, light source 10, (light source 10 that has both direction in Fig. 2, isIn order to take pictures light source to be provided to the camera that is positioned at both direction and position, respectively from different directions (preferablyFrom top and front both direction) carry out to light), display 6, charger 7, feeder 8, photoelectricity openPass 1, line slideway 2, receiving mechanism 9, controller 4 etc. form (as Fig. 2), and this equipment is mainly used inDetect screw outward appearance and size, sort out certified products and defective work.
Optoelectronic switch 1 is parts of detection machine, by transmitter 11, receiver 12 and testing circuit groupBecome, Main Function is: screw 3 travels forward along line slideway, when coming the light beam position of transmitter transmittingWhile putting, screw will block light beam, and now light beam is interrupted (as Fig. 1), the light letter that receiver receivesNumber greatly weaken, then by testing circuit, optical signal is converted into the signal of telecommunication, in the time that the light velocity is interrupted, can produceThe variation of a raw switching signal, exports to controller 4 thereby produce a triggering signal, and controller 4 connectsAfter receiving triggering signal, drives camera is taken.
Because screw is very little, all optoelectronic switches that must adopt light-focusing type, could precisely touch one to oneSend out, realize each screw and after same position, trigger camera and take coming, if light is beaten at several primary screws simultaneouslyUpper, triggering signal is by disorder.
1, be useful in optoelectronic switch on intelligent automatic screw detection machine except using correlation, all rightUse reflective. Reflective photoelectric switch forms single standarized component by transmitter and receiver, when there being footWhen enough combined light are returned to receiver, on off state will change, thereby produce a triggering signal outputGive controller.
2, optoelectronic switch, except being applied on the detection machine of guiding rail mechanism, also can be used on index dialOn the detection machine of mechanism.
Those skilled in the art will readily understand, under the prerequisite of not conflicting, above-mentioned each advantageous manner canFreely to combine, to superpose.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, not all at thisAny amendment of doing within bright spirit and principle, be equal to and replace and improvement etc., all should be included in the present inventionProtection domain within. The above is only the preferred embodiment of the present invention, it should be pointed out that for this skillThe those of ordinary skill in art field, not departing under the prerequisite of the technology of the present invention principle, can also makeSome improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
