3. change image and cross sheet mechanism: cross sheet mechanism and be by finishing, thereby reach the purpose of deceleration as the set of gears transmission combination 19 in the box.Finish framing as the ratchet in the box, lever body.What overcome drivewheel and follower speed difference is a cover clutch.
Please refer to Fig. 7, vision care circuit theory of the present utility model is summarized as follows:
Need make back and forth movement as box in this instrument, photo in the box also needs to move forward and backward, adopt the power source of dc motor according to the actual needs as the machinery of above-mentioned motion, here mainly use direct current generator to change the voltage direction of its two input, be after the rotor current direction changes, the characteristic that the rotating just of its direction of rotation changes, M among Fig. 7 1, M 2Be dc motor.
IC 1, IC 2Be the audio-frequency power amplifier integrated circuit, model is: TDA2822, be used as motor-drive circuit here, and TDA2822 includes two power amplifiers, and pin 1,3 is an outfan, and pin 6,7 is a positive input, and pin 8,5 is an inverting input.Be bridge connection among the figure, working condition is when 7 foot high level, 6 foot low levels, and pin 1 output positive voltage, pin 3 output negative voltages, the dc motor that is connected on pin 1,3 ends just changes, on the contrary the motor counter-rotating.
IC 3, IC 4Be the decade computer circuit, Q0-Q9 is the decimal scale outfan, and representing 0-9, C0 during high level respectively is the carry outfan, and R is the complex signal input, and CP is positive clock signal controlling end, IC 3, IC 4The effect here produces IC 1, IC 2Required control level.Action principle is as follows:
After the energized, capacitor C 4With resistance R 3Produce reset pulse, because capacitor C 4The voltage at two ends can not suddenly change, and R end i.e. 15 feet, instantaneously obtains a high level, and circuit is put 0, Q 0Outfan i.e. 3 feet is a high level, and all the other outfans are low level, so Q 1For low, as previously mentioned, this moment motor M 1Ying Zhengzhuan, when first carry pulse CP came, this circuit produced carry, Q 0Become low, Q 1Become height, motor M 1Become counter-rotating, Q when second carry pulse comes 2Become height, because Q 2Be connected with the R end, institute is so that circuit puts 0 again, so Q 0Be high level, Q 1Be again low level, motor M 1Just getting back to changes, CP pulse each like this, and the rotation direction of motor is changed once.
IC 6Model is CC40106, and it forms resistance R by six schmitt inverters 19, capacitor C 7, IC 6(1/6); Resistance R 7, capacitor C 8, IC 6(1/6) form single stabilization delay circuit respectively, the purposes here is the shake that disappears of contact switch, all the other 4 IC 6(1/6) in circuit, only plays inverting function.
IC 5Model is: CC4029, can preset forward-backward counter, and its pin is illustrated as: Q 1-Q 4Be data output end, this circuit need not, DP1-DP4 is a data input pin, PE is for putting numerical control system, the CI counter controls, B/D is two, decimal scale control, U/D is forward-backward counter control, operation principle: after the energized in capacitor C 6Under the effect, PE puts number for the high level circuit, because DP 1-DP 4Pass through resistance R 12, R 14, R 16, R 18Just connect power supply,, be equivalent to decimal number 15, because U/D passes through resistance R so circuit is changed to 8+4+2+1 10Just connect power supply, but this moment BG 3Conducting, so the U/D end is low level, circuit working is in the subtraction state, promptly the CP end detects K 3Open and close, after 15 pulses, just turn over 15 pictures and make IC as box 5Carry output, C0 exports a low level, by the phase inverter that C0 connect, IC 3CP end obtain required motor reverse signal.Motor M 1During counter-rotating, Q is mentioned in the front 1Be high, Q 0Be low, BG 3Base stage be low level, this moment BG 3End, U/D is a high level, IC 5Transfer to and add counting, at this moment audion BG 7-BG 4Base stage is high level entirely, BG 4-BG 7Conducting, inserting number is 0, when detecting K 3After 15 pulses of sending, C 0Import a low level again, make motor M 1Conversion direction just enters once more changes.
Audion BG 1, relay J 1, audion BG 2, relay J 2Form motor M respectively 1, M 2ON-OFF control circuit; Q 1During for high level, pass through resistance R 1, R 2, BG 1Conducting, relay J 1Adhesive, IC 1Power end often open contact K 4Direct power just, this moment, motor was in counter-rotating reviewing state, worked as Q 1During for low level, BG 1End relay J 1Not adhesive, IC 1Power supply is by normally closed contact K 5Just connect power supply again, at this moment motor M 1Just being in changes, crosses sheet state, motor M 1Change and do not change and be subjected to K 3Control.
Audion BG 2, relay J 2Conducting, by then depending on resistance R 4, diode D 3, D 4If the AND circuit D that forms 3, D 4Negative terminal be high level entirely, D 3, D 4End BG 2Base stage is by R 4Obtain bias current, conducting, J 2Adhesive, its normal opened contact K 6Closure, IC 2Work is so work as motor M 1During work, M 2Can not work.
K 1, K 2Be limit switch, be positioned at the two ends that look like the box running orbit,, when a certain direction is moved to the end, touch K switch when looking like box under motor-driven 1Produce a pulse, the motor wraparound makes box move to other direction, during to the other end, and another K switch 2Be closed, produce a pulse again, promptly make back and forth movement as box.
