Description

Electronically controlled stapling machine

The utility model relates to a kind of office appliance, relates in particular to the electronically controlled stapler that a kind of file binding is used, and is used for the bookbinding to file.

Existing Chang Yong hand stapler, people's fatiguability very during use, bookbinding speed is also very slow, makes the staple on the file uneven without limits because of insertion depth during bound document, thisly both required great effort time-consumingly, the poor again stapler of bookbinding quality day by day can not satisfy the needs of modern office chamber.Though existing also have electronically controlled stapler, structure and control circuit are not perfect.Though electronically controlled stapler is arranged now, microswitch is housed on casing, microswitch drives motor, motor is connected with gear train and drives eccentric wheel apparatus, eccentric wheel drives rocking arm interlock lever, installs on lever and presses the nail blade, and blade pumps along nail groove cover front end, blade is with staple push nail groove, and the place is shaped staple at nail-plate.But when binding, must press microswitch, the work of ability starter, it is inconvenient to go up band for operation.

The purpose of the utility model machine is that design is a kind of without manpower drives, bookbinding speed is fast, bookbinding quality is secure electronically controlled stapling machine.

The utility model realizes that the method for above-mentioned purpose is: switch is housed on casing, switch drives motor, motor is connected with gear train and drives eccentric wheel apparatus, eccentric wheel interlock blade slides up and down in nail groove cover, by resistance R 25, resistance R 26, resistance R 27, adjustable resistance VR1, the DU transmitting tube, receiving tube DU ', triode Q10 etc. form infrared transceiver circuit and substitute microswitch, described DU, DU ' is installed in bookbinding position side, emission, receiving head aims at, distance is inserted the paper that sets thickness between the two, the infrared light that DU launches, by DU ' absorption, DU ' is low-resistance, and the Q10 base stage is that electronegative potential is in and ends; Have paper to put into the bookbinding position, the impedance of DU ' changes, and the Q10 base stage is a high potential, the Q10 conducting, and be input to IC3, IC3 output control motor.Motor drives eccentric wheel, drives rocking arm interlock lever, installs on lever and presses the nail blade, and blade pumps along nail groove cover front end, and blade is with staple push nail groove, and the place is shaped staple at nail-plate.

IC1 is two RD flip-flop integrated circuits in the utility model, and first RD trigger is made up of the 1--7 pin of IC1, and second RD trigger is made up of the 9--15 pin of IC1, and two RD triggers are that series connection is used; Second RD trigger being made up of the 9--15 pin of resistance R 2, R3, R4, R6, R5, R9, capacitor C 1, C2, C6, C3, C5 and IC1 connects into monostable circuit, and the high potential of the 10 pin output of its IC1 is delivered to Q3 by R9 and outputed to the next stage circuit.The two RD triggers of IC1 adopt the MC14538BCP integrated circuit.

14 pin of IC1 connect stature level brake circuit in the utility model, and described head level is braked circuit by resistance R 2, R14, R16, R15, capacitor C 1, C9, C10, triode Q7, Q8, ic chip 1, quick-action switch L1 forms, and the common point of L1 and normally closed point are connected, the pulse signal of moment is through R14, the R15 dividing potential drop, the C10 time-delay of charging, the voltage after R15 obtains the dividing potential drop time-delay connects Q7, Q8 again, make the Q8 conducting, 14 pin of the colelctor electrode of Q8 and IC1 are connected.

The utility model compared with prior art has advantages such as simple in structure, easy to operate.

Description of drawings of the present utility model is as follows:

Fig. 1 is an electrical schematic diagram of the present utility model.

Fig. 2 is the electrical schematic diagram of another embodiment of the utility model.

Below in conjunction with description of drawings the utility model is described in further detail: as shown in Figure 1, this machine infrared ray control circuit includes mu balanced circuit, infrared transceiver circuit monostable circuit, signal output and circuit, head level brake circuit etc., wherein mu balanced circuit: be made up of resistance R 7 (1K Ω), capacitor C 4 (100 μ F), Zener diode ZD1 (5.1V), triode Q2 (S8050D).Voltage surely in 4.3V, is used for infrared transceiver circuit and monostable circuit.The quiet consumption of complete machine 5mA, when complete machine voltage was lower than 4.5VDC, circuit was not worked.Infrared transceiver circuit: by resistance R 1=R20 (1K Ω), adjustable resistance VR1 (10K Ω), transmitting tube DU1 (IR204), receiving tube DU1 ' (PT-928-5C), triode Q1 (LM9014C) etc. forms.DU1, DU1 ' are installed in a bookbinding position side, and emitting and receiving head is aimed at, between distance be to insert the paper that sets thickness.The infrared light that DU1 launches, under the situation of paper in quire, by DU1 ' absorption, DU1 ' is the low-resistance conducting state; The Q1 base stage is an electronegative potential, and Q1 is in cut-off state.Put into the bookbinding position as paper, paper (minimum 16# paper is more than 1) can stop or weaken infrared light, and the impedance of DU1 ' changes, because the variation of impedance changes the current potential of DU1 ' (R20, VR1 are offset control resistance).Electronegative potential on the former Q1 base stage has become high potential, makes the Q1 conducting, and paraphase gets electronegative potential, makes IC ₁5. pin is imported the triggering signal of electronegative potential.

Monostable circuit: form by resistance R 2 (4.7K Ω), resistance R 3=R4=R6 (10K Ω), resistance R 5 (24K Ω), resistance R 9 (100 Ω), capacitor C 1 (4.7 μ F), capacitor C 2=C6 (0.01 μ F), capacitor C 3=C5 (10 μ F), ic chip 1 (MC14538BCP).Because IC1 is monostable (two RD trigger) high efficiency integrated circuit, first RD trigger is by IC ₁1.～7. pin form, second RD trigger by IC1 9.～the pin forms, two RD triggers are series connection uses.IC1 is the variation of pin current potential 5., make IC1 10. pin the output of high potential is arranged.10. 2. determine by the RC product (delay circuit) of pin and the RC product (delay circuit) of 14 pin by IC1 for the time length of pin high potential output.

Signal output and connecting circuit: form by resistance R 9 (100 Ω) etc.IC1 is the high potential of pin output 10., gives Q3 circuit to next stage by R9

Head level brake circuit: form by resistance R 2 (4.7K Ω), resistance R 14=R16 (10K Ω), resistance R 15 (1K Ω), capacitor C 1=C9=C10 (4.7 μ F), triode Q7 (LM9014C), triode Q8 (LM9015C), ic chip 1 (MC14538BCP), quick-action switch L1 (LM1-01N-50H).Stapler is finished the once moment of action, former and the normal connection of making war of the common point of L1, become with normally closed point and connect, the pulse enable signal C9 of moment is by the voltage of moment, through R14, and the R15 dividing potential drop, after the C10 charging time-delay, R15 obtains the voltage after the dividing potential drop time-delay, makes the Q7 conducting, gets electronegative potential after the paraphase and supplies with Q8, make the Q8 conducting, the pin of the colelctor electrode of Q8 and IC1 is connected, and the pin of IC1 has become high potential by electronegative potential, second flip-flop operation of IC1, promptly adopt heavy triggering mode to remove in advance and dwindle pulse width, make the 10. pin of IC1 become electronegative potential by high potential, promptly do not have high potential output, played the effect of first step brake with buffer-type.

Above-mentioned variation, after the work once of drive late-class circuit, stapled paper can be pulled out from bookbinding (between infrared ray emission reception); If do not pull out paper, because second RD trigger of IC1 is also in running order, the 10. pin of IC1 still can not get output, the action that stapler also can not carry out next time or even beat.
