1) receiving a tapping instruction sent by a central control unit, judging whether the self-checking of the tapping robot is normal or not, if so, actuating a circumferential direction movement motor, an up-and-down direction movement motor and a cutter feeding and retracting motor of the tapping robot, and stopping after each motor finds a positioning origin point in the movement direction through an up-and-down limiting sensor, an ultrasonic sensor and a circumferential limiting sensor to finish tapping preparation work;
2) judging whether each motor in the step 1) returns to a positioning original point or not, if the positioning original point is returned, keeping the cutter feeding and retracting motor and the motor in the circumferential direction still, enabling the motor to move in the vertical direction to work, stopping the motor from rotating after the motor reaches a tapping setting position, and scanning the tree diameter contour by an ultrasonic sensor arranged below the cutter holder; each motor is used as a motion cutting track according to the scanning information;
3) the feeding and retracting motor starts to rotate forwards, the feeding and retracting motor drives the rubber cutter to act, the ultrasonic sensor below the rubber cutter starts to work while feeding, the feeding depth information of the rubber cutter is sent out in real time, when the rubber cutter reaches the preset bark depth, the feeding action is finished, and the step 4 is carried out;
4) the feeding and retracting motor stops working, the circumferential direction movement motor and the up-down direction movement motor rotate forwards and work simultaneously at a preset speed matching relation, and the circumferential direction movement motor and the up-down direction movement motor drive the rubber cutter to perform spiral movement from bottom to top;
5) and judging whether the rubber cutter reaches a cutting end point, stopping rotating the circumferential direction motion motor and the up-down direction motion motor when the rubber cutter reaches the cutting end point, reversely rotating the cutter advancing and retracting motor, and quickly reversely rotating the circumferential direction motion motor, the up-down direction motion motor and the cutter advancing and retracting motor after the cutter point of the rubber cutter withdraws from the bark to reach a calibrated original point to finish a cutting process.
9. The control method according to claim 8, characterized in that: the lift angle of the spiral motion path of the rubber cutter is 20-30 degrees.
10. The control method according to claim 8, characterized in that: and the upper and lower limit sensors and the circumference limit sensor detect the end point information, and the rubber cutter reaches the cutting end point.
