Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.
As shown in fig. 1, a rotary folding type manipulator for picking tea single buds comprises a clamping jaw mechanism, a rotary folding mechanism and a conveying mechanism.
The clamping jaw mechanism comprises a first mounting plate 4-1, a clamping jaw cylinder 4-2 and a transmission assembly.
The clamping jaws are a pair of claw arms 4-5 which are rotatably positioned on the first mounting plate, and articulated shafts 4-51 are arranged between the claw arms and the first mounting plate. And clamping gaskets 4-7 are arranged on the clamping surfaces of the tail ends of the claw arms, the clamping gaskets are made of flexible materials with softness similar to that of fingers, and first sensors 4-8 are further arranged at the tail ends of the claw arms. The first sensors are a pair of correlation type photoelectric sensors (comprising a transmitting end and a receiving end) which are matched with each other, and the two first sensors are respectively fixed at the tail ends of the claw arms through sensor mounting plates 4-9 (the sensor mounting plates and the clamping gaskets are arranged on two sides of the claw arms).
The clamping jaw air cylinder is fixed on the first mounting plate, and the transmission assembly is used for transmitting power of the clamping jaw air cylinder to drive the clamping jaw to open and close. In the transmission assembly, a rack 4-4 is coaxially fixed with a piston rod of a clamping jaw air cylinder through a connecting rod 4-3, the rack is double-sided teeth, two jaw arms are symmetrically arranged on the rack, fan-shaped teeth 4-6 are arranged on the jaw arms, and the fan-shaped teeth are coaxially arranged with a hinged shaft of the jaw arms and meshed with the rack.
The rotary folding mechanism is used for driving the clamping jaw mechanism to rotate. In the rotary folding mechanism, a rotary folding motor 3-1 is fixed on a second mounting plate 2-3, the second mounting plate is U-shaped, and a rotating shaft of the rotary folding motor penetrates through the second mounting plate and then is fixed with the first mounting plate through a shaft end connector 3-2 of the rotary folding motor.
The conveying mechanism is used for driving the rotary folding mechanism to rotate. In the conveying mechanism, a conveying motor 2-1 is fixed on one side of a third mounting plate 1, a harvesting box 5 and a second sensor 2-5 are fixed on the other side of the third mounting plate, a rotating shaft of the conveying motor penetrates through the third mounting plate and then is fixed with the second mounting plate through a conveying motor shaft end joint 2-2, and a sensor retaining sheet 2-4 matched with the second sensor is fixed on the conveying motor shaft end joint. The second sensor is a photosensor.
The axis of the rotating shaft of the conveying motor is perpendicular to the axis of the rotating shaft of the rotary folding motor, and the axis of the rotating shaft of the rotary folding motor is coaxial with the axis of the clamping jaw cylinder piston rod in the stretching direction.
The working principle of the invention is as follows:
1) initial state: as shown in fig. 2, the piston rod of the clamping jaw cylinder extends out, the clamping jaw is opened, and the sensor blocking piece shields the second sensor;
2) when tea leaves are positioned in the clamping jaws, the optical signals emitted by the emitting ends of the first sensors are blocked by the tea leaves, and the receiving ends cannot generate corresponding electric signals, so that the piston rods are retracted by the clamping jaw cylinders to drive the racks to move, the clamping jaws close to clamp the tea stems, and the tea stems cannot be damaged due to the fact that the clamping gaskets made of flexible materials are mounted at the tail ends of the jaw arms;
3) the rotary folding motor is started to drive the clamping jaw mechanism to rotate for a certain angle, so that the clamped tea stalks are folded, and the rotary motor rotates reversely to rotate the clamping jaw mechanism back to the original position;
4) the conveying motor is started to drive the clamping jaw mechanism and the rotary folding mechanism to rotate clockwise (in the direction indicated by an arrow in fig. 2), and meanwhile, the sensor blocking piece is far away from the second sensor (the second sensor generates a signal); when the clamping jaw mechanism drives the tea leaves to rotate over the highest point and reach the upper part of the harvesting box, the piston rod of the clamping jaw air cylinder extends out to open the clamping jaw, the tea leaves fall into the harvesting box, and the single-bud harvesting action of the tea leaves is finished;
5) the conveying motor drives the clamping jaw mechanism and the rotary folding mechanism to rotate anticlockwise in the opposite direction, when the sensor blocking piece blocks the second sensor, signals are interrupted, the conveying motor stops acting, the mechanical arm is reset to prepare for picking next time, and therefore continuous picking of tea leaves is achieved.
The above description is only for the purpose of illustrating the present invention and is not intended to limit the scope of the present invention, and any person skilled in the art can appreciate that the technical solutions and their concepts disclosed in the present invention are equivalent or modified within the scope of the present invention.
