Preferably, the screw driver further comprises a teaching box, wherein the teaching box is used for setting the number of product screws of the screw driving controller, the minimum rotating time of the electric screwdriver, the overtime time, the reset delay of the locking cylinder, the material sensing enabling, the number of the residual screws, the production times, the starting signal and the unlocking signal.
Preferably, the screw beating tool transmits the photoelectric sensing signal to the screw beating controller, and the screw beating controller can control and transmit the locking cylinder to the screw beating tool.
The invention also provides a method for preventing the screw from being missed, which comprises the following steps:
s1, starting an electric screwdriver and starting to drive screws;
s2, screwing, wherein a screwing controller collects starting time and torque in-place signals of the electric screwdriver;
s3, judging whether the screws are repeatedly driven or not and whether the screw counting is needed or not according to the starting time and the torque in-place signal of the electric screwdriver; wherein, the collection of the screw torque in-place signal is as follows: the output voltage of the electric screwdriver is increased to 30V when the electric screwdriver rotates, the output voltage of the electric screwdriver is reduced to 0V after the torque reaches the upper limit set by the electric screwdriver, and a screwing controller collects and detects the falling edge of 30V to 0V to judge the torque in-place condition; if the screwing torque is not in place, the electric screwdriver does not output any information, and the screwing controller judges that the screw is unqualified if the screw cannot acquire any information within a certain time range; and the collection of the starting time of the electric screwdriver is as follows: inputting the set minimum rotation time T1 for the electric screwdriver by the teaching box; a person operates the electric screwdriver to rotate the electric screwdriver, the electric screwdriver stops rotating from starting to rotating until the torque is in place, the time for acquiring the actual rotation of the electric screwdriver by the screwing controller is T2, and if the T2 is less than the T1, the torque in place signal is invalid and is not counted; if T2 is larger than T1, the torque-in-place signal is valid and counted.
The invention has the beneficial effects that:
according to the invention, the starting time and the torque in-place signal of the electric screwdriver are judged through the screwing controller, so that the effective times of screwing are counted, and the counter is judged to be not counted by the repeated screwing procedure, thereby preventing the screw from being missed to be screwed.
