Embodiment
Referring to figs. 1 through Fig. 6, the utility model NEEDLE DETETOR embodiment is described further.
But the utility model can realize in various different formats, and the utility model should not be construed as and is limited to exemplary embodiment set forth herein.There is provided exemplary embodiment to contribute to more fully understanding the utility model.
As shown in Fig. 1 to 2, a kind of NEEDLE DETETOR, comprises worktable 1, and worktable 1 is provided with frame 2, frame 2 being provided with the testing circuit for detecting broken needle, frame 2 being provided with protective cover 5, and protective cover 5 outside surface adopts electrostatic painting.Worktable 1 is provided with the travelling belt for article transmission, the dual-side of travelling belt is provided with the baffle plate avoiding article to skid off travelling belt, protective cover 5 is provided with the opening assigning baffle plate.Frame 2 arranges protective cover 5, and adopts electrostatic painting at protective cover 5 outside surface, can avoid in testing process by extraneous intense light source and electromagnetic interference.Frame 2 is provided with controller 3 and warning circuit 9, and controller 3 and warning circuit 9 are arranged on the outside of protective cover 5 and are electrically connected testing circuit.Frame 2 is provided with warning circuit 9, and controller 3 and alarm are arranged on the outside of protective cover 5 and are electrically connected testing circuit.Testing circuit, comprises sensor circuit 6, monostable circuit 7, counting circuit 8 and warning circuit 9; Sensor circuit 6, comprises infrared transmitter and infrared detector, and infrared transmitter and infrared detector are distributed in the both sides of travelling belt and are arranged in frame, for detecting broken needle signal; Monostable circuit 7, response broken needle signal, and this signal is carried out processing and identifying, and output action signal; Counting circuit 8, response actuating signal, carries out count decoding display to actuating signal; Warning circuit 9, response actuating signal, sends alerting signal, prompting staff, and find broken needle article, warning circuit 9 is hummer 4.Testing circuit can detect that broken needle signal effectively counts, and facilitates data statistics, to analyze broken needle phenomenon in the future, thus to the equipment of broken needle may be caused to keep in repair, reduces broken needle rate.
The circuit diagram of testing circuit as seen in figures 3-6, is made up of T1 slot optical coupling, IC1 monostalbe trigger, IC2 ~ IC4 count decoding display circuit.Counting region is 0 ~ 999.Display adopts common cathode LED charactron.This circuit has the automatic clear function that powers on.Also realize manually resetting by the Reset button.Slot optical coupling lTR9608, R1, R2 form photoelectric detective circuit, are responsible for the number of times of detected article to convert voltage pulse signal to.Slot optical coupling is made up of infrared transmitter and phototriode, and during work, infrared transmitter sends Infrared and projects on phototriode through the groove of optocoupler, phototriode conducting, collector output low level; When Infrared detected material interdicts, phototriode ends, and collector exports high level.Block a slot optical coupling and export a pulse, the number of therefore pulse is exactly the number of times that detected material blocks.
R3, C2, C3 and IC1 form monostable circuit.Its effect carries out shaping to the pulse signal that slot optical coupling transmits, and removes noise signal, improves antijamming capability.The model of IC1 is NE555, is connected in timing capacitor by input end TH and discharge end DIS in circuit simultaneously, is high level when trigger end TR is flat.After power supply is connected.Because TR pin is high level, the output of IC1 is low level, inner discharge tube conducting, DIS holds conducting over the ground, and the voltage on timing capacitor C3 is 0V, TH input end is also 0V, the output of IC1 is always low level state, and this state is exactly the stable state of monostalbe trigger.Low level is become from high level when slot optical coupling exports, and time this low level <1/3VCC (Vcc=5V is the supply voltage of IC1).The output terminal of IC1 reverses, and 3 pin export and become high level by low level, meanwhile, and the discharge tube cut-off of IC1 inside.Power supply is charged to C3 by R3, and temporary stable state starts.Through to after a while, as voltage >2/3Vcc on C3, monostalbe trigger reverses, 3 pin export and become low level from high level, discharge tube conducting, C3 holds rapid discharge by the DIS of IC1, and original stable state got back to again by monostalbe trigger.Measured object often blocks a slot optical coupling, and it is the pulse of td that monostalbe trigger exports a width, and this pulse is delivered to counter and gone counting and display.C4 is filter capacitor, can improve monostalbe trigger job stability.
The decimal add counter that counting circuit is made up of IC2 ~ IC4.The circuit model of IC2 ~ IC4 is CD40110.It is decimal system reversible counter/latch/decoder/drivers.Have plus-minus counting, counter status latches, the functions such as Seven pieces digital displaying decoding output.CD40110 has 2 counting clock input end CP and CPDN to be used separately as to add counting clock input and subtracts counting clock input.In order to simply clear, do not provide CPDN pin in the drawings.Be high level when the carry output CY of 40110 is flat, when counter has carry, CY exports negative pulse.When multi-disc cascade, only need CPUP end CY being connected to subordinate CD40110, just can form multi-bit counter.R is clear terminal, and TE is that counting allows end, and LE is the preset end of latch.After power supply is connected, count decoding display circuit, by C1, R4 automatic clear, can be pressed " reset button " as required at any time and be reset by count decoding display circuit during work.Charactron is common cathode charactron, and its display brightness regulates by coupled resistance.
Warning circuit is made up of triode, amplifier and hummer, and triode is NMOS tube, and NMOS tube just can conducting when high level.Only just understand trigger alarm circuit working when receiving and exporting high level, start hummer.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
