Field of the Invention The present invention relates to a power tool control device, and more particularly to a control device that can reduce the labor of an operator and improve the work efficiency of the hand tool. [Prior Art] The hand tool referred to herein refers to a hand-held power generated by an electric motor: two, for example, an electric screwdriver, a dental high-speed drilling machine, an electric engraving knife, etc. (4) The hand tool has a handle on its grip. The pressure plate switch controls whether the electric motor inside the hand tool is operated or not, that is, if the operator expects the hand tool to be held only, it must be - directly press and hold the buckle plate switch, and we take the operator on the production line as an example. Assume that a &, - working day, must be locked 25,000 tired: 糸 ': a screw lock to pay the time 〇 5 seconds, that is, to spend WO. The above (4) method, for (4) must continue to hold down ^ when the coffee is minutes 'This is a negative 栌 for the operator's material fingers, will be "occupied professional injury. Another due to the operator's responsibility ❹, also directly affects its efficiency. 【Abstract】 Turning blood ^ The above can be seen, the traditional hand tools through the buckle plate switch to determine the impact of continuous operation; cause physical and physical burden, while further review, and: The main object of the present invention is to provide a power tool control device 4 200819251 which includes a technical means for achieving the foregoing purpose, and the control device envelops the flow; the microprocessor is used as an arithmetic control center, and has a built-in base drive Connecting, the motor motor driving circuit is connected to the electric motor of the hand tool and the electric motor of the hand tool through a conversion interface, and is connected with the input end of the microprocessor 11 to provide The time-base driving process built into the microprocessor by the touch-sensitive device is based on "two: meaning that after receiving a drive command" will be executed - when specified, 'wide range' With one touch, the one-touch hardness of the drive command can be sent. If the author does not need to keep pressing any switch, the work can be easily performed: not only is it more convenient to operate, but also reduces the operator's burden, thereby improving the work. effectiveness. The aforementioned control device can be built in the hand tool (4), or it can be used alone. [Embodiment] Please refer to the first, with 5 200819251 卜 and connect with the hand tool (鸠) through the wire (10). The hand tool (100) is exemplified by an electric screwdriver. The a m cookware application is not limited to an electric screwdriver, and is an object that is provided with an electric motor internally to generate power and is applicable to the present invention. 8 to a circuit block diagram of a possible embodiment of the present invention, please refer to the third figure h 'mainly by - microprocessor (1)), a motor drive circuit, - conversion interface (13), 1 circuit (14), etc. The microprocessor (11) is inserted as an arithmetic control, and the input terminal is provided with a one-touch key (15) for receiving a drive command or a stop command sent by the operator. The conversion interface (13) is connected to the motor drive circuit, and the microprocessor (1)) has a built-in time base driving process for sending the drive signal to the motor drive circuit after receiving the drive command generated after the early touch key (10) is pressed. ). The output of the motor drive circuit (12) is connected to the electric motor (4) of the hand tool so that the *microprocessor (1)) sends the drive signal to drive the electric motor (20) and control its rotational speed. The feedback circuit (14) is connected between the electric (4) up (2 ()) and the microprocessor (1)) feedback terminals to feedback the condition of the electric motor (2 〇) to the microprocessor (11). Referring to the fourth embodiment, a detailed circuit diagram of a preferred embodiment of the present invention is shown. The electric motor (20) is driven by a three-phase power supply uvw, and the conversion interface (13) and the motor drive circuit (12) are respectively There are three sets of lines to control the three-phase power supply separately. The feedback circuit (14) connected between the electric motor (20) and the microprocessor (11) also has three sets of lines for respectively returning the load current condition of the electric horse 6 200819251 (〇) as an adjustment. The basis for driving the signal. In addition, the time base driving process built in the microprocessor (11) performs the driving action in the private room on a time basis. For the detailed flow, please refer to the fifth figure. After the system starts, it is judged. Whether the operator presses a one-touch, (15) to drive out the drive command (5〇1), if not, repeats the above steps, if 疋 then sends the drive signal (502), the process of sending the drive signal (5〇2) In the middle, it will be judged whether the driving time of a Dunting is over (5〇3), whether the motor torque exceeds the preset value (5〇4), and whether the one-touch key (15) is pressed again (5〇6), When the foregoing step (5〇3)(5〇4)(5〇5) is not established, the process returns to step (502) to continuously perform the driving work, if the step (5〇3) (5〇4) (5〇5) is used When it is established, it stops outputting the driving signal (5〇6), and finally returns to the step (5〇1). As can be understood from the above description, the present invention provides a time-based driving process, It can send 30-instruction one-touch keys to control the operation of the internal (4) motor of the hand tool and “the one-touch key can generate the drive command once it is touched, such as the i-shaped Then, the operator does not have to work hard to continuously press on the one-touch button; and since it is based on time, it is only necessary to press the one-touch button of the hand tool once to allow the hand tool to run for a period of time. For example, when it is used to lock the screw, if it is set to rotate for 5 seconds, touch the one-touch button once, and the electric screwdriver will run for 5 seconds. If the lock is only required for one second, then when the screw is locked, The torque of the electric screwdriver will exceed the set value, and then the operation will stop. If the operator touches the one-touch button again when the screw is locked, the electric screwdriver will also stop running. This not only reduces the operator's operation. Burden, can also meet different usage occasions and 7 200819251 习惯 习惯 ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha The second one-touch key only takes 25 time to pay, and the operation is n, that is, according to the first minute, the cumulative time of touching the one-touch key is only payable. 25, _ = traditional ^ hold the shackle switch operation mode, lock comparison, operation _ ^ (four) The board switch reaches the negative protection of the phase of 2. 8 minutes. 丄 丄 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 166 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The burden is also increased because the lock can be locked at one time.
