Description
Technical field
The present invention relates to a kind of instruments used for education, be specially a kind of location of workpiece pick-up unit.
Background technology
Along with the widespread use of instructional device equipment, efficiency and the quality of rote teaching device product are greatly improved.But in teaching experimental equipment, how to ensure that part to be processed time can locate reliably in work, and preventing that work in-process from installing error or the reason such as location is inaccurate because of workpiece, the positioning error of generation, causes experimental result undesirable.
Summary of the invention
The technical problem to be solved in the present invention is: the location of workpiece pick-up unit that a kind of accurate positioning simple in structure is provided.
For addressing the above problem, the present invention adopts technical scheme to comprise: switching signal produces mechanism, signal conversion processing circuit, codified radio transmitter and wireless receiving circuit, and wherein signal generation mechanism comprises fixed bar, motion bar, elastic mechanism; Conversion processing circuit comprises switch contact, switch process circuit, carries out change-over circuit and power-supply circuit.
Between transmitting and reception, form a wireless network by fixed carrier radio communication.Be that testing agency has when action of detection, produce one by the switch triggering of contact and open signal to signaling conversion circuit, change-over circuit obtains out signal driver wireless launcher and transmits, and after receiving circuit gets signal simultaneously, carries out corresponding computing feedback to experimental provision.
Location of workpiece pick-up unit of the present invention has simple in structure, light small and exquisite, solid durable, and maintenance cost is extremely cheap, applicable to workpiece sensing and the location of various experimental facilities production lines.Meanwhile, adopt radio communication cooperative mechanical location, simplify wiring, meet the experimental teaching demand of modern measure.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is switch transition plate structure schematic diagram of the present invention.
Fig. 3 is switch transition plate circuit theory diagrams of the present invention.
Embodiment
As shown in Figure 1, location of workpiece pick-up unit of the present invention, comprise support 8, described support 8 is installed on the workpiece support platform of Practical training equipment, on described support 8, be provided with fixing lever 1 and movable lever 2, on described movable lever 2, wear elastic mechanism 3, described movable lever 2 upper ends arrange, lower end arranges testing agency 4, on described support 8, be also provided with can detected activity lever 2 positions detecting unit 5, detection signal is sent to wireless signal transmitting module 6 by described detecting unit 5, described wireless transmitter module 6 is sent to reception of wireless signals module 7 by signal and carries out signal processing judgement.
Described wireless signal transmitting module 6, for coding radio transmitter, because first fixing transmission frequency, is wireless signal emission as long as switch on power.Described reception of wireless signals module 7, for coding wireless receiving circuit, according to wireless signal, drives corresponding relay work, produces a road normally closed of the He Yi road signal of often making war simultaneously.Described elastic mechanism 3 is spring.Described testing agency 4 is vacuum cup, and vacuum cup is pneumatic element, and sucker the inside is provided with pore, in the time inhaling workpiece, bleeds, and while knocking off part, inflates.In the course of the work, sucker plays and picks up workpiece and discharge the effect of workpiece, adopts sucker to have and have as testing agency 4, simple in structure, reliable, cheap, durable, pollution-free, do not hinder the advantages such as workpiece.
As shown in Figure 2, detecting unit 5 described above is switch transition plate, and described switch transition plate is provided with testing circuit 9, and the contact D of the switch SW of described testing circuit 9 connects motion bar B, the copper sheet contact 10 of another contact C connecting valve change-over panel.As shown in Figure 3, its principle is described testing circuit 9: when switch SW signal closes, triode Q1 ground level is high level, the E utmost point of triode Q1 and the cut-off of the C utmost point, and output terminal OUT output low level, closes the power supply that transmits; When SW switch is when opening signal, triode Q1 ground level is low level, triode Q1 saturation conduction, and output terminal OUT out-put supply, starts wireless signal transmitting module 6 wireless signals.Described testing circuit 9, has disconnection of wireless transmitter module 6 battery supplies when cost is low, easy to maintenance, mechanism does not work, plays energy-conserving action.
Principle of work: the movable lever 2 of testing agency 4 and the fixing lever 1 closed state with flicking mutually, produce switching value; Because the contact D of the switch SW of testing circuit connects motion bar B, another contact connects the copper sheet contact 10 of conversion circuit, in the time that moving upward, testing agency 4 encounters when detecting workpiece, movable lever 2 runs to position A from position B, the contact D of testing circuit and contact D open circuit, status signal is opened in generation, testing circuit triode Q1 saturation conduction, and OUT output voltage is to radio transmitter wireless signal emission; In the time that testing agency 4 moves downward, when movable lever 2 runs to position B from position A, produce closure state signal, the closed conducting of the contact D of testing circuit and contact D, produce off status signal, change-over circuit triode Q1 cut-off, OUT is output as 0V, and powered-down stops wireless signal transmitting module 6 wireless signal emissions to reception of wireless signals module 7; By movable lever 2 and the fixing lever 1 closed state with flicking mutually, produce switching value issuing Practical training equipment as carrier and carry out signal and process judgement by wireless signal.
In experimental facilities process, experimental facilities picks up location of workpiece detection erecting device by mechanical arm, on experimental facilities work top, pass through vacuum cup, draw the workpiece needing, carrying by mechanical arm is put into workpiece the assigned address top that need to put, the process mechanical arm of putting at workpiece drives the location of workpiece to detect erecting device and moves downward, when workpiece is being transferred in the height stroke of regulation, just in time aim at the part of assigned address workpiece position depression, do not encounter testing agency, illustrate that contraposition successfully controls sucker and take, workpiece accurately enters position; Instantly in motion process, encounter peripheral projection position and wait, the state that movable lever 2 and the fixing lever 1 of testing agency 4 flick produces switching value, and experimental facilities relocates after notifying mechanical arm by corresponding program correction position, specifies station until accurately put into.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, allly make an amendment, reduce, be equal within the spirit and principles in the present invention replacement etc., within all should being included in protection scope of the present invention.
