Number of times, if it is incorrect to lock, by control main frame 20 show that information warning is in display device 22.It addition, control main frame 20
In addition to rotating forward number of times except being calculated by enumerator 23 judges whether to rotate forward the number of times that number of times reaches locking screw, control
Main frame 20 processed can also calculate the operating number of turns of motor 15, Yi Jigen by the tach signal received from Rotating speed measring module 122
The enabling signal received according to startup detection module 121 calculates the operating number of turns stopped from beginning to escape of electric screw driver 30,
Judge that locking is the most correct.The most main with control by startup detection module 121 of the present utility model, Rotating speed measring module 122
Machine 20 judges whether electric screw driver 30 locks screw, and its detailed description is as follows.
Microprocessor 16 of the present utility model can according to the torsion calculated judge electric screw driver 30 whether by screw locking,
This memorizer 17 stores torque data during electric screw driver 30 locking screw.Through the following steps, it is judged that whether electric screw driver 30
Correct locking screw.Referring to Fig. 4, in step S401, operating detector unit 12 judges whether electric screw driver 30 starts to start,
Wherein, operating detector unit 12 can be according to whether receive enabling signal to judge whether electric screw driver 30 starts.When operating inspection
After survey unit 12 judges that electric screw driver 30 starts running, in step S402, operating detector unit 12 judges electric screw driver 30
Motor 15 is to rotate forward or reversion, wherein, operating detector unit 12 can according to the kind of enabling signal (height of such as signal or
Low etc.) judge that the motor 15 of electric screw driver 30 is rotating forward or inverts.In step S403, when the motor 15 of electric screw driver 30 exists
During rotating forward, when this microprocessor 16 calculates torsion, the operating number of turns and operating when motor 15 rotating forward beginning to motor 15 stops
Between.
Otherwise, in step s 404, if motor 15 is when reversion, then without carrying out the calculating of torsion.In step S403
After middle calculating motor 15 rotates forward torsion when beginning to motor 15 stops, in step S405, being sentenced by this microprocessor 16
Disconnected screw the most correctly locks.In step S406, during this microprocessor judges screw the most correctly locks, pass through
Torsion, the operating number of turns and duration of runs when electric screw driver 30 is rotated forward by microprocessor 16 and the torsion being stored in memorizer 17
Power, the operating number of turns and comparing the duration of runs, torsion, the operating number of turns and the duration of runs when operating are less than being stored in
The torsion of memorizer 17, the operating number of turns and the duration of runs, microprocessor 16 exports one and does not locks signal.In step S 407,
Torsion, the operating number of turns and the duration of runs when operating are more than the torsion being stored in memorizer 17, the operating number of turns and fortune
Turning the time, microprocessor 16 exports a stopping signal and stops electronic to driving module 11, driving module 11 according to stopping signal
The operating of son 30.Electric screw driver 30 of the present utility model is made to have protection mechanism, to prevent electric screw driver by above-mentioned method
30 are rotated further after screw locking and cause motor 15 to burn out.
It addition, the electric screw driver work detection device that can also pass through of the present utility model is in the display device controlling main frame 20
Show the duty of electric screw driver 30 on 22, in step S405, torsion when electric screw driver 30 rotates forward, the operating number of turns with
And the duration of runs is less than the torsion being stored in memorizer 17, the operating number of turns and the duration of runs, the electricity of display device 22 display
The torsion of dynamic bottle opener 30, the operating data such as the number of turns and the duration of runs are normal (time such as by torsion, the operating number of turns and operating
Between etc. data be shown as blue etc.).And torsion, the operating number of turns and the fortune in step S406, when electric screw driver 30 rotates forward
When turning the time more than the torsion being stored in memorizer 17, the operating number of turns and the duration of runs, what microprocessor 16 was exported stops
Stop signal can be transferred to control main frame 20, when controlling torsion, the operating number of turns and the operating that main frame 20 shows in display device 22
Between etc. data be abnormal (such as by shown in red to torsion, the operating data such as the number of turns and the duration of runs etc.), by above-mentioned
Mode, electric screw driver work detection device of the present utility model except be possible to prevent electric screw driver 30 motor 15 over-running and
Burn out, more can understand the duty of each electric screw driver 30 in the display device 22 controlling main frame 20 and whether work
Abnormal, allowing staff it will be seen that the use situation of electric screw driver 30, if there being exception, electric screw driver 30 can be carried out as early as possible
Maintenance and replacing.It addition, at this it should be noted that torsion, the operating number of turns and the duration of runs stored by memorizer 17 can
Be electric screw driver 30 dispatch from the factory time the most set in advance, it is also possible to being staff additionally sets by controlling main frame 20
, do not limit at this, and be ability in how torsion, the operating numerical value such as the number of turns and the duration of runs being stored in memorizer 17
Known to the person skilled of territory, and non-emphasis of the present utility model, do not repeat them here.
Refer to Fig. 5, when controlling main frame 20 and opening, in step S501, display device 22 shows start-up picture.
After display device 22 has shown start-up picture, in step S502, it is electronic that display device 22 display counter 23 is calculated
The torsion of bottle opener 30, the counting number of turns or the duration of runs, control main frame 20 and can set electric screw driver 30 shown during start
Torsion, the counting number of turns or the zero duration of runs, or the torsion of the electric screw driver 30 that counted of enumerator 23 of display during start,
Torsion, the counting number of turns or the duration of runs when counting number of turns or the duration of runs are that last time, electric screw driver 30 operated, the not office at this
Limit.In step S503, control main frame 20 and detect whether to receive working signal, if controlling main frame 20 to receive working signal,
In step S504, controlling main frame 20 and transmit command signal to electric screw driver 30, in step S505, electric screw driver 30 receives life
Making signal start working, and return to step S502 after end-of-job, it is electronic that display device 22 display counter 23 is calculated
The torsion of bottle opener 30, the counting number of turns or the duration of runs.If controlling main frame 20 to be not received by working signal, enter step S506,
Control main frame 20, in setting pattern, can be controlled default or the environment set etc. of main frame 20, until receiving work
Signal enters step S503.
By electric screw driver work detection device of the present utility model, except having the motor mistake being possible to prevent electric screw driver
The setting that degree rotates and burns, more can work as electric screw driver by controlling to supervise on main frame the working condition of each electric screw driver
Can repair or replace in the very first time during operation irregularity.
Above-described detailed description of the invention, is entered the purpose of this utility model, technical scheme and beneficial effect
One step describes in detail, be it should be understood that and the foregoing is only detailed description of the invention of the present utility model, is not used to limit
