In the field of current manufacturing, a locking device is a very important tool, such as an electric screw driver, which can be used to tighten or loosen screws, bolts, etc., and especially in the field of assembling mobile phones, computers, etc., the requirements for torque control accuracy and intelligence of the electric screw driver are also increasing.
The torque of the existing electric screw driver is usually adjusted manually by a mechanical device arranged on the screw driver head, on one hand, the mechanical torque adjusting mechanism makes the whole mechanical structure of the electric screw driver relatively complex; on the other hand, when the torque is adjusted by using the mechanical torque adjusting mechanism, the control precision is difficult to guarantee, particularly when the torque is controlled below 1kg × cm, the precision is difficult to guarantee, the rotating speed of the screwdriver cannot be continuously adjusted, the servo positioning function is not provided, faults such as lock missing, tooth sliding, floating and the like cannot be monitored, and the requirements of higher-end manufacturing industry are difficult to meet.

referring to fig. 1, fig. 1 is a schematic structural diagram of a servo locking device according to an embodiment of the present invention, where the servo locking device includes a batch nozzle 1, a batch head 2, a reduction box 3, a motor 4, an encoder 5, a housing 6, and a control module, and the control module includes a touch screen module 7 and a servo driver 8 in signal connection with the touch screen module 7. The screwdriver head 2, the reduction box 3 and the motor 4 are positioned in the shell 6 and are sequentially and axially connected; the encoder 5 is located within a housing 6 which is mounted to the end of the motor 4 and is connected to a servo drive 8 by a control cable. The batch nozzle 1 is arranged on the batch head 2, a user can replace the proper batch nozzle 1 according to actual requirements, and the touch screen module 7 and the servo driver 8 are positioned outside the shell 6, namely the control module is positioned outside the shell 6.

The touch screen module 7 can also display locking data in real time, such as locked torque, locking position data, locking time and/or locking number of the screw. The servo driver 8 is respectively connected with the motor 4 and the encoder 5 through a control cable, and is used for monitoring and controlling the running state of the motor 4 according to the working parameters transmitted by the touch screen module 7 and the information fed back by the encoder 5. The encoder 5 can monitor information such as the rotation speed and the position information of the motor 4, and feed the monitored information back to the servo driver 8, and the servo driver 8 can process the information fed back by the encoder 5, so that the running state (such as the rotation speed and the output torque) of the motor 4 can be further accurately controlled. In one embodiment, the servo locking device further comprises a power supply 11 connected to the control module for supplying power to the touch screen module 7 and the servo driver 8. In another embodiment, the servo locking device can also utilize an external power module to provide power.
The motor 4 may be a coreless motor (a high-speed, fast-response permanent magnet motor), and the servo driver 8 is a high-precision motor controller with position, speed, and current control.
When the servo locking device is used for locking a workpiece, for example, locking (screwing) one screw of the workpiece, a user can set working parameters (control parameters) such as locking torque, locking rotational speed and locking turns of the servo locking device through the touch screen module 7 according to actual requirements, the working parameters are transmitted to the servo driver 8 in real time, for example, the touch screen module 7 can transmit the set working parameters to the servo driver 8 in real time in a can communication mode, the servo driver 8 controls the motor 4 to operate according to the working parameters, the motor 4 drives the reduction gearbox 3 in the operation process to further drive the batch head 2 and the batch nozzle 1 to rotate, the reduction gearbox 3 can reduce the operation speed of the motor 4, and transmit the operation speed and the output torque of the motor 4 to the batch head 2 and the batch nozzle 1; meanwhile, the rotation speed and position information of the motor 4 can be monitored by the encoder 5, and the monitored data is fed back to the servo driver 8. Like this, user's accessible touch-sensitive screen module 7 sets up the working parameter of servo lock payment device at the lock payment in-process, touch-sensitive screen module 7 gives servo driver 8 with this working parameter real-time transmission, servo driver 8 is then according to the running state of the information monitoring and the control motor of this working parameter and encoder 5 feedback, can screw up simultaneously, logical judgement such as shut down, thereby the electronic mode has replaced the moment detection mechanism of traditional mechanical type, the mechanical structure of servo lock payment device has been simplified, the precision of detection has been improved, make servo lock payment device more intelligent, the function is more diversified. Meanwhile, the servo locking device can realize the continuous adjustment of working parameters such as locking torque, locking rotating speed, locking turns and the like.
In practical application, the touch screen module 7 includes a memory card, and the memory card may be configured to store locking data of the screws in real time, where the locking data may include a locked rotation (fastening) torque of each screw, locking position data of each screw, locking time and/or locking number of each screw, and the locking position data is a rotation number or a rotation number from the start of rotation to the end of rotation of the motor 4 when one screw is locked, and the locking number is the number of locked screws. The memory card may also store information such as the temperature of the servo drive 8 and the model number of the batch nozzle 1. Therefore, the data in the memory card can be read and stored through the upper computer, and data support is further provided for analyzing and tracing the locking quality of the workpiece.
The servo locking device provided by the embodiment can detect the locked-rotor state of the motor 4 through the servo driver 8 to judge whether the screw reaches the tightening state. Specifically, the servo driver 8 detects the current of the motor 4 and obtains the rotating speed and the position information of the motor 4 through the encoder 5, monitors and controls the running state of the motor 4 according to the working parameters set by the touch screen module 7, the current, the rotating speed and the position information of the motor 4, and determines that the screw reaches the screwing state when the rotating speed of the motor 4 rapidly decreases and the current of the motor 4 rapidly increases to the maximum value. In practical application, a user can set the locking time in the screw locking process through the touch screen module 7 according to actual requirements, for example, the locking time is set to 50ms, and the screw can be locked more tightly by setting the locking time. At this time, the servo driver 8 can determine that the screw is tightened when the rotation speed of the motor 4 is rapidly decreased and the current reaches the maximum value and maintains a lock time.
Referring to fig. 2, the change curve of the current and the rotation speed of the motor during the locking process of the screw is shown in fig. 2, wherein a curve a is a rotation speed curve, a curve B is a current curve, which is a starting stage of the motor 4, a constant-speed operation stage, a locked-rotor maintaining stage, and a stopping stage. In the locked-rotor stage (locking stage), the servo driver 8 detects that the rotating speed output by the motor 4 is rapidly reduced and the current value output by the motor 4 in real time is rapidly increased, and the screw can be judged to be in the sitting process (screwing process) through the phenomenon. Meanwhile, the servo driver 8 can adjust the locking time of the screw by controlling the locked-rotor maintaining time of the stage (r), which can also be set by the touch screen module 7. In this locked-rotor maintaining period, the current output from the motor 4 reaches the maximum, and the screw reaches the tightened state after the end of this time. In addition, a user can set a locking torque through the touch screen module 7, the touch screen module 7 transmits the set locking torque to the servo driver 8, the servo driver 8 determines the maximum amplitude of the output current of the motor 4 according to the locking torque, and controls the output torque of the motor 4 according to the maximum amplitude, that is, the servo driver 8 can control the output torque of the servo locking device by controlling the maximum amplitude of the output current of the motor 4.
In order to ensure the accuracy of the output torque, the servo driver 8 is further configured to calibrate the output torque of the motor 4 according to a torque calibration coefficient, which is stored in the servo driver 8 or is a received calibration coefficient transmitted by the touch screen module 7. In a specific embodiment, the corresponding relationship between the current and the output torque may be calibrated under the rotation speed conditions of 0RPM (Revolutions Per Minute), 100RPM, 200RPM, 300RPM, 400RPM and 500RPM, respectively, to obtain a torque calibration coefficient, and the torque calibration coefficient is stored in the servo driver 8, and the user may also calibrate the output torque of the servo locking device by selecting the calibration coefficient through the touch screen module 7.
In a specific embodiment, the user may set the lock-up rotation speed of the servo lock-up device through the touch screen module 7, and the lock-up rotation speed may be set in a segmented manner, for example, the lock-up rotation speed may include a first rotation speed and a second rotation speed, wherein the first rotation speed is greater than the second rotation speed. The touch screen module 7 transmits the first rotating speed and the second rotating speed to the servo driver 8 in a can communication mode, at this time, the servo driver 8 controls the motor 4 to start to operate at the first rotating speed in a first time period, and controls the motor 4 to operate at the second rotating speed in a second time period. The first time period and the second time period may also be set by the touch screen module 7. Referring to fig. 3, it shows the variation curve of the lock-up rotation speed, in which the motor 4 starts at a high rotation speed (rotation speed 1) when starting, and automatically reduces to a low rotation speed (rotation speed 2) when the screw is tightened, so as to simultaneously take account of the lock-up speed and the lock-up precision, and also relieve the impact of the servo lock-up device on the hands when the lock-up rotation is stopped.
The rotational speed and the operating time are set by the touch screen module 7 and in a further exemplary embodiment can also be learned by a self-learning function of the servo locking device.
Specifically, the touch screen module 7 is further configured to generate a learning instruction when detecting an operation for starting the learning mode, and send the learning instruction to the servo driver 8. When receiving a learning instruction sent by the touch screen module 7, the servo driver 8 controls the motor 4 to run at a constant speed, detects position travel data of the motor 4 through the encoder 5, records locking time of the screw, plans a locking track of the screw according to the detected position travel data and the recorded locking time, and obtains an optimal running track of the screw. At the same time, the position travel data and the lock payment time data can also be stored in a data storage chip in the servo driver 8. Fig. 4 shows a learning process of the servo lock apparatus, as shown in fig. 4, after a user starts a learning mode through the touch screen module 7, the servo driver 8 drives the motor 4 to operate at a constant speed Va; and when the servo driver 8 detects that the motor 4 is locked, recording position stroke data Pa and locking time Ta of the motor 4, and planning a normal locking track of the screw through Pa and Ta. In one embodiment, three rotational speeds can be planned: (1) the motor 4 is operated at a constant speed of 2 × Va, with an operating time of Ta/3; (2) the motor 4 is operated at a constant speed Va, and the operation time is 2 × Ta/9; (3) the motor 4 runs at a constant speed Va/2 and the running time is 2 × Ta/9; see in particular fig. 5.
On the other hand, the servo driver 8 may determine whether the screw is thread-slipping and/or thread-lifting based on the position stroke data of the motor 4 and the lock-up time. One method of determination may be: if the total locking time of the currently locked screw is greater than Ta, judging that the screw has a tooth slipping fault (the screw slips and cannot be screwed up all the time); and if the total locking time of the currently locked screw is less than Ta/2, judging that the screw has a floating fault (the screw is locked in advance, and the fault generally occurs in a short time). In practical application, the determination time of the floating height fault and the sliding tooth fault can be set through the touch screen module 7.
In the screw track self-learning process, the current output by the motor 4 in real time can be monitored by the servo driver 8, the tooth-entering time point of the screw is judged according to the change of the current, and then the action track and the locking time of the screw are calculated from the time point. Referring to fig. 6 specifically, the locking of the screw may be divided into five processes of tooth searching, tooth entering, screwing, seating and fastening, and the servo driver 8 may determine the process section where the screw is specifically located through the current output by the motor 4. The tooth searching process is a process from the beginning of rotating the screwdriver head 2 by the driving of the motor 4 to the placing of a screw into a screw hole, the process does not belong to a process of locking the screw, the tooth searching time is random, the time can be ignored in the self-learning process of the screw track, the tooth entering time is determined through the change of the current output by the motor 4, as shown in fig. 6, the time t1 when the current is suddenly increased is determined as the tooth entering time, so that the accuracy of the learned data can be ensured, and the stroke error before the tooth entering is eliminated. In practical applications, the torque (current) amplitude of the dental implant can also be set by the touch screen module 7.
In summary, all the control parameters and control modes of the servo lock device can be continuously set by the touch screen module 7.
According to the servo locking device provided by the embodiment, on one hand, a user can set working parameters such as locking torque, locking rotating speed and locking turns of the servo locking device through the touch screen module according to actual requirements, the working parameters are transmitted to the servo driver connected with the touch screen module in real time, the servo driver controls the motor to operate according to the working parameters, and meanwhile, the rotating speed and position information of the motor are monitored through the encoder, so that a traditional mechanical torque setting mechanism is replaced by an electronic mode formed by the touch screen module and the servo driver, the mechanical structure of the servo locking device is simplified, and the detection precision is improved. On the other hand, the servo locking device provides a self-learning function of the locking track of the screws, and can perform self-learning of the locking data of each type of screw, so that the locking track of the screws is planned, and the locking quality and the locking precision are guaranteed. Meanwhile, the touch screen module is used for replacing the traditional key setting, so that the set content is richer, and the intelligent degree is higher. Moreover, the servo locking device can automatically detect the sliding tooth and floating height faults of the screw, and improves the locking quality of the screw. In addition, the servo locking device can monitor and store the locking data of each screw in real time, and provides data support for analyzing and tracing the locking quality of the workpiece.

The touch screen module 7 can detect whether the processed workpiece is replaced or removed through the infrared detection unit 9, and when the workpiece is replaced or removed, a signal of the infrared detection unit 9 is changed, so as to detect whether the processed workpiece is replaced or removed.
The locking of each workpiece is finished by the number of the screws required by the fixing, and the alarm unit 10 can give an alarm when the locking is abnormal. The servo driver 8 counts the locked screws, adds one to the count value to obtain the number of the lock payments when one screw is successfully locked, and sends the number of the lock payments to the touch screen module 7 for real-time display. If the touch screen module 7 judges that the number of the locking sets does not reach the set total number of the screw locking sets and the infrared detection unit 9 detects that the workpiece is replaced or removed, the locking sets to be abnormal, an alarm instruction is generated at the moment, the alarm instruction is sent to the alarm unit 10, and the alarm unit 10 gives an alarm according to the alarm instruction to prompt a user that the locking sets are not completed currently by screws, so that the condition of missing locking is prevented. If the number of the locking sets reaches the set total number of the screw locking sets, after the workpiece is updated, the servo driver 8 resets the current number of the screw locking sets.
The servo driver 8 can also give an alarm through the alarm unit 10 when judging that the screw has the tooth slipping fault and/or the floating fault, and prompt a user that the screw has the tooth slipping fault and/or the floating fault.
The servo locking device provided by this embodiment can determine whether the number of the screws in the locking device reaches the set total number of the screws in the locking device through the screw locking counting function of the infrared detection unit and the servo driver, and when the number of the screws in the locking device does not reach the set total number of the screws in the locking device and the infrared detection unit detects that the workpiece is replaced or removed, the servo locking device gives an alarm through the alarm unit to prompt a user that the screws in the locking device are not completed currently, so that the condition of missing locking is prevented.
