Description

Electronic automatic stapler

The utility model relates to a kind of office appliance, relates in particular to the automatic stapler of electronics that a kind of file binding is used.

Now not only speed is slower when the bookbinding amount is big for Chang Yong hand-pushing stapler, and people's hand is also tired, and with the file of binding out because of insertion depth mechanism without limits, and irregular; And the lever transmission of selling on market is by by dress thing pull switch and the electronics stapler of working, high impracticable because of its complex structure, repair rate again.

The purpose of this utility model be to design a kind of simple in structure, compact, be convenient to operate, the automatic stapler of electronics that speed is high, with the labour intensity that alleviates the people with improve work efficiency.

The purpose of this utility model is to realize like this, the electronics stapler includes shell, substrate, pressure is ordered frame, iron core, coil, supply socket, order latch plate between frame and the substrate in pressure, and be located at and press the pin of following closely on the frame of ordering, the pressing piece, the axis of guide of pressing piece, the big spring that is connected with the pressing piece, latch plate, the pointer assembling machine structure, it is characterized in that on the substrate of stapler, being provided with a photoelectric sensor, it and electric control system link, when bound document is put into, photoelectric sensor just sends signal, control circuit just triggers the controllable silicon conducting, be arranged at the just energising of coil under the substrate, and the pressure that will link to each other with iron core is ordered frame and is inhaled downwards, bookbinding is finished at this point, control circuit outage then, and stitching plate resets under the elastic force effect of latch plate.

This stapler is because of adopting photo-electric control and mechanical structure combining, and is reasonable in design, compact conformation, thereby volume ratio has the electronics stapler and dwindles, and the reliable in action quality is good; Compare with manual stapler commonly used, the automaticity height, operator's labour intensity is low, the efficient height.

With drawings and Examples structure of the present utility model is further narrated below.

Description of drawings:

Fig. 1 is this electronics stapler overall structure schematic diagram.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is the electrical control block diagram.

Fig. 5 implements example for electrical control.

By Fig. 1～4 as seen, this electronics stapler comprises shell 1, substrate 11, pressure is ordered frame 2, iron core 6, coil 7, supply socket 12, order latch plate 10 between frame 2 and the substrate 11 in pressure, it is a groove-shaped frame that described pressure is ordered frame 2, it is connected by bearing pin 20 with substrate 11, pressure is ordered frame and is provided with and orders pin 18, pressing piece 16, the axis of guide 19 of pressing piece and the big spring 15 that is connected with the pressing piece, nail pin location latch plate 17 and pointer assembling machine structure 14, it is characterized in that file is sent into the position on substrate 11 is provided with a photoelectric sensor 3, be connected with connecting rod 5 and iron core 6 at position, stapler 2 termination, and iron core partly is exposed to above the substrate 11, part is inserted below the substrate 11, below the substrate at this iron core position, be provided with coil 7, be provided with control section 8 near coil 7 places, described control section 8 comprises rectification circuit, clamp-pulse generator, with controllable silicon drive circuit three parts and wiring board 9 that this three part is installed, rectification circuit input end and power supply join, output and clamp-pulse generator join, photoelectric sensor 3 links with the clamp-pulse generator input, the output of clamp-pulse generator and the SCR control utmost point link, and the silicon controlled major loop joins with power supply by the back of connecting with coil 7.

The power rectifier in the control section 8 is made up of transformer B, bridge rectifier QL and regulator block 7806 among the embodiment of this electronics stapler as seen from Figure 5, the impulse generator that has the control action of delaying time that clamp-pulse generator is made up of switching tube BG1, BG2 and time base circuit NE555 and resistance capacitance, controllable silicon drive circuit then is controllable silicon SKG.

The electronics stapler of said structure, when bound document is delivered to gutter pos, photoelectric sensor sends signal, clamp-pulse generator just sends pulse after connecing this signal, and the time-delay a period of time, at this moment between the inner control pulse exist always, just conducting always of controllable silicon, meanwhile coil 7 is charged and to pull at iron core 6 downward, and is being with the stapling frame downward, orders pin and just hammers in the file; When delay time arrives, pulse disappears, and the frame of stapling together resets under the elastic force effect of spring leaf 10; And spring 15 will order pin immediately after sending and send forward under staple, and stapled file can take out.After ordering pin and using up, adorn pin by 14 pairs of stapling framves of pointer assembling machine structure, continue then to use; In addition, the dress pin partly resets well in the pressure nail frame in order to make, and can press nail frame tail end that one back-moving spring 13 is set.

In addition, adjustable for the binding position that makes the binding file, in the present embodiment photoelectric sensor is designed to be threaded position control 4, make the stapler scope of application of present embodiment big like this, and the file binding position consistency after the bookbinding, to bind attractive in appearancely, quality is good.

In sum, this electronics stapler is owing to adopt the miniaturization photo-electricity control section to combine with the mechanically binding parts, make that it is simple in structure, novel, volume is little, performance good, use is firm, low price, and bookbinding speed is fast, can reduce labor intensity, thereby have good economic, practical value.
