Embodiment 1
[0052] See figure 2 , is a process flow of a method of controlling the opening and closing state of the tool Figure 1 , wherein, the method is applicable to a tool that includes an inner knife driven by a motor that rotates relatively in the outer knife, as shown in the figure, the method specifically includes:
[0053] Step S101, when receiving the tool opening / closing command, start the motor to drive the inner knife to rotate normally;
[0054] Step S102, according to the initial position of the inner knife relative to the outer knife at the preset time, determine the corresponding initial Hall position of the motor at the preset time;
[0055] Step S103, stop the motor when it is detected that the motor rotates a preset distance from the initial Hall position, so that the inner knife rotates to a position relative to the motor by the inertia of the motor after stopping the motor The outer knife is in the corresponding open / closed state.
[0056]The above method sends ...
Embodiment 2
[0074] This embodiment provides a device for realizing the method in the above-mentioned embodiment 1, see Figure 5 , is a structural frame of a device that controls the opening and closing state of the tool Figure 1 , wherein the device is suitable for being installed in a tool that includes an inner knife driven by a motor and relatively rotating in an outer knife. As shown in the figure, the device 200 includes a command receiving module 210, a position confirmation module 220, and a motor control module 230 , wherein, the command receiving module 210 is adapted to start the motor to drive the inner knife to rotate normally when receiving the knife opening / closing command; the position confirmation module 220 is adapted to The initial position of the time, determine the initial Hall position corresponding to the motor at the preset time; the motor control module 230 is suitable for stopping the motor when detecting that the motor rotates a preset distance from the initial...
Embodiment 3
[0080] See Figure 7 , the present embodiment also provides a cutter 300, including an outer cutter 110, an inner cutter 120, and a motor 310 suitable for driving the inner cutter 120 to rotate relatively in the outer cutter 110, and the cutter 300 also includes a memory 320 and a processor 330, wherein the memory 320 stores a set of programs, and the processor 330 is configured to invoke the programs stored in the memory 320 to execute the method described in any implementation item in Embodiment 1 of the present invention.
[0081] The above tool, when sending the tool open / close command to the tool, detects the initial Hall position of the inner knife relative to the outer knife at the preset time according to the Hall sensor induction magnet, and controls the motor to drive the inner knife from the Stop the motor when the initial Hall position rotates a preset distance, so that the inner knife rotates to the corresponding open / closed state relative to the outer knife by re...
