(2) Fan 42
As shown in fig. 1, the blower 42 is a conventional device for drawing air from the device and accelerating the flow of air in the device, so that the pressure in the device is reduced and suction is generated.
3. Mechanism of operation of the device
1) The device is placed above tea tender shoots 00, the No. 1 photoelectric sensor array 11 works, the fan 42 is started, and the end effector 10 generates suction.
2) The end effector 10 adaptively adjusts the size of an inlet of the end effector 10 by controlling an opening in the shutter type cutter 12 according to the result of the photoelectric sensor array 11 in the No. 1, so that the tea shoots 00 are prevented from being sucked into the end effector 10 and the tea shoots 00 are prevented from being sucked into the end effector 10, and the tea shoots 00 automatically enter the end effector 10 in an air suction mode, thereby reducing the precision of algorithm positioning and improving the precision of tea shoot 00 collection.
3) If the tea tender shoot 00 is in the end effector 10 and the suction position is not aligned, only a part of the tender shoot enters the end effector 10 or is in a skew state, the No. 1 photoelectric sensor array 11 senses the position and the size of the initial shoot, and the position of the end effector 10 is adjusted to enable the tea tender shoot 00 to completely enter the end effector 10.
4) The first and second sections of the photoelectric sensor array 11 of the 1 st section sense the position and size of the tea tender bud 00, when sensing that the cross section of the tender bud reaches the minimum, the rotating motor 13 is started, the driving gear drives the spiral chassis 123 to rotate, the cutting blade 122 contracts and pinches off the tender bud.
5) The tender shoots are sucked into the end effector 10 along the hose 15, and are sensed by the 1 st section of the photoelectric sensor array 11 and the 1 st section of the photoelectric sensor array 11, the rotating motor 13 rotates in the opposite direction, and the driving gear drives the shutter type cutter 12 to return to the original position, so that the air flow and the air pressure difference in the conveying pipeline 20 are recovered.
6) Picked tea tender shoots 00 are conveyed to a tea storage device 30 through a conveying pipeline 20, the tea tender shoots 00 fall into a tea storage pipeline 31 due to gravity and suction force of an exhaust pipeline 41, a movable gate at the bottom of the tea storage pipeline 31 is in a normally closed state, the tea storage pipeline 31 is in a closed state, no gas flows, and the suction force of the device is enhanced; the tea shoots 00 are temporarily stored in the tea storage pipeline 31, when the bottom pressure sensing module 312 senses a certain pressure, the motor 314 at the bottom of the tea storage pipeline 31 is started to drive the pressure sensor module 312 to be opened, the pressure sensor module 312 is attached to the slide way 313, the tea shoots 00 fall into the tea storage box 32, and then the pressure sensor module 312 is closed.
7) Under normal conditions, pressure sensor module 312 can experience the internal situation through pressure sensor, open pressure sensor module 312 when reaching certain pressure, however because the pressure is less than external pressure in storing up tea pipeline 31, in addition tealeaves burgeon 00 is fluffy, the space between tealeaves burgeon 00 and tealeaves burgeon 00 is big, cause tealeaves burgeon 00 to pile up too high problem in storing up tea pipeline 31, store up suitable high 2 nd photoelectric sensor array 311 of adding in tea pipeline 31, when 2 nd photoelectric sensor array 311 is sheltered from for more than 3 seconds, pressure sensor module 312 opens automatically.
Second, the application method
The operation steps are as follows:
firstly, working a photoelectric sensor array 11 in a 1 st stage, and placing a tea picking device above tea tender shoots 00;
secondly, the fan 42 is started, the end effector generates 10 suction force, and tea tender shoots 00 are sucked into the end effector 10;
and thirdly, the position of the end effector 10 is adjusted through the identification of the 1 st photoelectric sensor array 11.
Fourthly, the first section and the second section of the 1 st photoelectric sensor array 11 recognize that the cross section of the tea tender shoot 00 is minimum, the rotating motor 13 is started to drive the shutter type cutter 12 to contract and clamp off the tea tender shoot 00, the tea tender shoot 00 passes through the third section of the 1 st photoelectric sensor array 11 through suction, and the tea tender shoot 00 is determined to pass through the end effector 10 and the shutter type cutter 12 is reset.
Fifthly, the tea tender shoots 00 enter the tea storage device 30 through the conveying device 20, and the picking work is finished.
