The specific embodiment can further be understood architectural feature of the present invention and beneficial effect thereof for making your auditor and the public, and the spy reaches embodiment in conjunction with the accompanying drawings the specific embodiment of the present invention is described in detail as follows:
See also Fig. 1, shown in be the combination stereogram that electric screw driver of the present invention is provided with multi-functional operation keyboard and multi-functional state display screen.Among the figure,, be provided with 12 and dual-colored LED pipes 11 of digital LED pipe of interactive multi-functional operation keyboard 13 and one two at the upper position of electric screw driver 1.By in Multi-Function Keyboard shown in Figure 2 13 and the state display screen structure schematic diagram as can be seen, this Multi-Function Keyboard 13 is provided with Starting mode switch key 131, counter is provided with key 132, rotating speed switch key 133 and turns to switch key 134.
Be provided with electric screw driver schematic block circuit diagram such as Fig. 3 of multi-functional operation keyboard and multi-functional state display screen.Be not difficult to expect that for only for the electric screw driver of implementing first purpose of the present invention, then display circuit partly is unwanted in Fig. 3 theory diagram.
According to Fig. 3 theory diagram, further electrical schematic diagram such as Fig. 4 in the present embodiment, in the present embodiment, operation keyboard 13 is the forms that adopt membrane keyboard, certainly, the function of this operation keyboard also can adopt in the prior art keyboard type of other form of generally using to realize, as dial switch etc.Below, in conjunction with Fig. 4 electrical schematic diagram, describe the course of work of electric screw driver in detail.Each terminal on each button terminal of operation keyboard 13 and pushing or the activation lever mode gauge tap circuit 16 is connected to each corresponding interface of microprocessor control circuit 14 respectively, the model of microprocessor 14 is PIC16F877, and each corresponding terminal of the status display circuit 15 that each output signal terminal of microprocessor control circuit 14 then constitutes with one two LED charactron 12 and dual-colored LED pipe 11 is connected.Electric screw driver is by external power supply module power supply, and the power switch of opening power assembly, electric screw driver promptly show residing state, as long as electric screw driver is not to be in the rundown process of screw, promptly can carry out various settings easily.
-Starting mode is set: flicking " starts P/L " key 131, can freely select " activation lever mode (LS) " or " pushing Starting mode (PS) ", at this moment, display window LED charactron 12 shows that " PS " then is the pushing Starting mode, show that " LS " then is the lever display mode, repeat this operation, can in two kinds of Starting mode, select to switch.
-rotating speed is set: flicking rotating speed switch key 133, can select the height of screwdriver working speed, state display window to change LED charactron 12 shows that " H " then be at a high speed, while dual-colored LED pipe 11 Chang Liang; Show that " L " is low speed, dual-colored LED pipe 11 flickers simultaneously.
-being provided with and turning to: flicking turns to switch key 134, can change the direction of rotation of screwdriver, and state display window to change LED charactron 12 shows " F " then for just changeing (turning clockwise), i.e. the tightening direction of screw, while dual-colored LED pipe 11 is shown in green; State display window to change LED charactron 12 shows that " R " then is counter-rotating (being rotated counterclockwise), is the exit axis of screw, and dual-colored LED pipe 11 is shown in red simultaneously.
The setting of-counter: the flicking counter is provided with key 134, display window 12+the numerical digit partly flickering, repeat again by this key, then display window 12+numerical digit part from 0 to 9 switches.Setting+numerical digit part after, automatically switch to a position state be set, this moment display window 12 individual bit position flicker, carry out and+after number is the same operation of part, withdraws from counter automatically state be set, and in display window 12, demonstrate the numeral of setting.In the present embodiment, used counter is a down counter, supposes that certain station need twist 10 screws, and then counter is set to 10.Behind the tightening operation of finishing a screw effectively, display is shown as remainingly uncompletedly tightens several 9, behind the tightening operation of finishing 10 screws, buzzer will send prompt tone, display window twice of the demonstration " 00 " of then glimmering, represent that this circulation finishes, and enters the tightening operation of next 10 screws automatically.
As a same reason, for only for the electric screw driver of implementing first purpose of the present invention, then the display circuit part also is unwanted in Fig. 4 electrical schematic diagram, and its specific embodiment is more simple than the foregoing description, does not repeat them here.
The electrical schematic diagram of Fig. 5 when then to be electric screw driver of the present invention with LCD constitute display circuit.Display window with liquid crystal display with the difference of LED pipe, display mode difference just, under the prior art condition, the liquid crystal display display mode can show more information.
