The content of the invention
The technical problem to be solved in the present invention is：A kind of location of workpiece detection means of accurate positioning simple in construction is provided.
To solve the above problems, the present invention is included using technical scheme：Switching signal generation mechanism, signal conversion processes electricity
Road, codified radio transmitter and wireless receiving circuit, wherein signal generation mechanism include fix bar, motion bar, elastic machine
Structure；Conversion processing circuit includes switch contact, switch process circuit, performs change-over circuit and power-supply circuit.
A wireless network is constituted by fixed carrier radio communication between transmitting and reception.I.e. testing agency has detection dynamic
When making, an ON signal is produced to signaling conversion circuit by the switch triggering of contact, it is wireless that change-over circuit obtains ON signal driving
Emitter transmission signal, while receiving circuit, which gets to experimental provision accordingly calculate after signal, handles feedback.
The location of workpiece detection means of the present invention has simple in construction, and light compact, solid durable, maintenance cost is extremely low
It is honest and clean, it is applicable to workpiece sensing and the positioning of various experimental facilities production lines.Meanwhile, positioned using radio communication cooperative mechanical,
Simplify wiring, meet the experimental teaching demand of modern measure.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the invention.
Fig. 2 changes plate structure schematic diagram for the switch of the present invention.
Fig. 3 is switch change-over panel circuit theory diagrams of the invention.
Embodiment
As shown in figure 1, the location of workpiece detection means of the present invention, including support 8, the support 8 is installed on Practical training equipment
Workpiece support platform on, be provided with the support 8 on fixed lever 1 and movable lever 2, the movable lever 2 and wear elasticity
Mechanism 3, the movable upper end of lever 2 is set, and lower end, which is set, is additionally provided with detectable movable shelves on testing agency 4, the support 8
The detection unit 5 of the position of bar 2, the detection unit 5 will detect that signal is sent to wireless signal transmitting module 6, the wireless hair
Penetrate module 6 and send the signal to the progress signal transacting judgement of reception of wireless signals module 7.
The wireless signal transmitting module 6, to encode radio transmitter, because first fixing tranmitting frequency, as long as connecting
Power supply is transmitting wireless signal.Described reception of wireless signals module 7, for coding wireless receiving circuit, according to wireless signal, drives
Dynamic corresponding relay work, while producing opened point all the way and all the way normally closed signal.Described elastic mechanism 3 is spring.Institute
The testing agency 4 stated is vacuum cup, and vacuum cup is to be provided with stomata inside pneumatic element, sucker, is taken out when workpiece is inhaled
Gas, is inflated when putting workpiece.In the course of the work, sucker plays a part of picking up workpiece and release workpiece, and inspection is used as using sucker
Surveying mechanism 4 has and has, simple in construction, reliably, cheap, durable, pollution-free, the advantages of do not hinder workpiece.
As shown in Fig. 2 detection unit 5 described above is switch change-over panel, the switch change-over panel is provided with detection circuit
9, the switch SW of the detection circuit 9 contact D connection motion bars B, the copper sheet contact of another contact C connecting valve change-over panels
10.The detection circuit 9 is as shown in figure 3, its principle is：When switching SW signals closure, triode Q1 ground levels are high level, three
Pole pipe Q1 E poles and the cut-off of C poles, output end OUT output low levels, close transmission signal power supply；When SW switches are ON signal,
Triode Q1 ground levels are low level, and triode Q1 saturation conductions, output end OUT out-put supplies start wireless signal transmission mould
The wireless signal of block 6.The detection circuit 9, with cost is low, easy to maintenance, mechanism not operation disconnection of wireless transmitter module 6
Battery supply, plays energy-conserving action.
Operation principle：The state that the movable lever 2 of testing agency 4 is mutually closed and flicked with fixed lever 1, produces switch
Amount；Due to detect circuit switch SW contact D connection motion bars B, the copper sheet contact 10 of another contact portion conversion circuit, when
Detection workpiece is encountered by testing agency 4 when moving upwards when, movable lever 2 runs to position A from position B, detection circuit
Contact D and contact D open circuits, produce open state signal, detect circuit triode Q1 saturation conductions, OUT output voltages are to wireless hair
Transmit-receive radio road launches wireless signal；When testing agency 4 moves downward, movable lever 2 from position A run to position B when, produce
Closure state signal, contact D and contact D the closure conducting of detection circuit, produces off status signal, change-over circuit triode Q1 is cut
Only, OUT is output as 0V, closes power supply and stops the transmitting wireless signal of wireless signal transmitting module 6 to reception of wireless signals module 7；
The state for being mutually closed and flicking with fixed lever 1 by movable lever 2, produces switching value and is used as carrier by wireless signal
Issue Practical training equipment and carry out signal transacting judgement.
The location of workpiece is detected that erecting device is picked up by experimental facilities by manipulator during experimental facilities, is set in experiment
By vacuum cup on standby work top, the workpiece needed is drawn, workpiece, which is put into, by the carrying of manipulator needs what is put
Above specified location, mechanical hand-motion location of workpiece detection erecting device is moved downward during workpiece is put into, and works as work
Part is directed at the part of specified location workpiece position depression in height stroke as defined in decentralization, just, will not hit on testing agency, says
The bright successfully control sucker that aligns takes, and workpiece accurately enters position；Instantly peripheral projection position time, testing agency are encountered in motion process
The state that 4 movable lever 2 is flicked with fixed lever 1 produces switching value, and experimental facilities notifies manipulator to press corresponding program amendment
Repositioned behind position, until being accurately put into specified station.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Make an amendment, reduce within god and principle, equivalent substitution etc., should be included in the scope of the protection.
