[0091] like Figures 1 to 5 As shown, the adaptive robotic arm 1 for collecting plant phenotypic information of the present invention includes a robotic arm body 100, a detection mechanism 200 and a lifting mechanism 300. The lifting mechanism 300 drives the detection mechanism 200 to move up and down on the robotic arm body 100. The detection mechanism 200 is provided with a detection device for collecting plant phenotypic information.
[0092] In specific implementation, Figure 1 As shown, there are two adaptive robotic arms for collecting plant phenotypic information of the present invention that are symmetrically distributed on the left and right, and a conveyor belt 2 is provided between the two adaptive robotic arms 1. The plants to be collected are placed on the conveyor belt 2 for transportation. When the plants are transported between the two adaptive robotic arms 1 of the present invention, the conveyor belt 2 stops running, and the adaptive robotic arms 1 of the present invention collect phenotypic information of the plants.
[0093] The detection mechanism 200 includes a main plate 210, a rotating mechanism 220, a collector 230 and a balance sensing component 240. The main plate 210 is connected to the lifting mechanism 300, and the rotating mechanism 220, the collector 230 and the balance sensing component 240 are respectively connected to the main plate 210. The rotating mechanism 220 includes a first rotating shaft 221, a second rotating shaft 222, a clutch component 223, a detection driver 224 and an adaptive driver 225, wherein the clutch component 223 is used to drive the first rotating shaft 221 and the second rotating shaft 222 to separate from each other along the axis direction, or drive the first rotating shaft 221 and the second rotating shaft 222 to approach each other along the axis direction and connect into one. The detection driver 224 is connected to the first rotating shaft 221, and the adaptive driver 225 is connected to the second rotating shaft 222. The collector 230 is connected to the second rotating shaft 222, and the balance sensing component 240 senses the offset angle of the second rotating shaft 222 and is connected to the adaptive driver 225.
[0094] During the information collection operation, when the first rotating shaft 221 and the second rotating shaft 222 are connected as a whole, the detection driving member 224 drives the first rotating shaft 221 and drives the second rotating shaft 222 to rotate, so as to adjust the collection angle of the collector 230 located on the second rotating shaft 222. When the balance sensing component 240 senses that the angle of the collector 230 is deviated, adaptive adjustment is performed, at which time, the clutch component 223 drives the first rotating shaft 221 and the second rotating shaft 222 to separate from each other along the axial direction, and the adaptive driving member 225 drives the second rotating shaft 222 to rotate for angle calibration.
[0095] Combination Figures 2 to 7 In the present invention, the detection mechanism 200 further includes a housing 250, a first rotating shaft 221 is fixedly connected to the housing 250, and a second rotating shaft 222 is movably connected in the housing 250. When the detection driving member 224 drives the first rotating shaft 221 to rotate, the housing 250 and the first driving shaft 221 rotate simultaneously. When performing adaptive adjustment, the second driving shaft 222 and the housing 250 are movable in both the circumferential and axial directions, the first driving shaft 221 and the second driving shaft 222 are separated, and the adaptive driving member 225 drives the second rotating shaft 222 to rotate and adjust, which will not deflect the position of the first driving shaft 221 and the housing 250.
[0096] The present invention controls the clutch between the first rotating shaft 221 and the second rotating shaft 222, so that the collection angle of the collection device can be flexibly adjusted. By setting the second rotating shaft 222 to be movably connected to the shell 250, the angle of the shell 250 can be kept unchanged during the adjustment process. The unchanged angle of the shell 250 provides a corresponding reference for the adjustment of the collector 230, which facilitates the calibration of the collectors 230 on the two adaptive mechanical arms 1, so that the collectors 230 maintain the best acquisition posture, which is conducive to comparing the collected content, avoiding the large difference in the collection angles on the two mechanical arms due to wear between the parts of the collection device during long-term use, making the collected content more accurate, which is conducive to improving the accuracy of collecting plant information.

The pneumatic cylinder controller 330 is connected to the lifting pneumatic cylinder 320. The slide rail 310 is connected to the robot arm body 100. The lifting pneumatic cylinder 320 drives the main plate 210 and the collector 230 thereon to move up and down along the slide rail 310. The pneumatic cylinder controller 330 includes a pressure gauge connected to the lifting pneumatic cylinder 320. The pressure gauge detects the air pressure in the lifting pneumatic cylinder 320 to determine the height position of the main plate 210.
[0103] Among them, there are two grooves 213 opened on the main plate 210 and they are symmetrically distributed about the slide rail 310, there are also two first cavities 211 and two second cavities 212 respectively and they are symmetrically distributed about the slide rail 310, and the first cavity 211 is located on the side where the two grooves 213 face each other, and the second cavity 212 is located on the opposite side of the groove 213, that is, starting from the slide rail 310 to the left and right, the first cavity 211, the groove 213, and the second cavity 212 are distributed in sequence.

[0105] An electromagnetic ring 2233 is fixedly installed in the inner cavity of the first toothed disk 2211, and the upper and lower parts of the first toothed disk 2211 are respectively fixedly sleeved with a current valve 2235 connected to the connecting line 2232, and the current valve 2235 is fixedly connected to the electromagnetic ring 2233. The side of the first toothed disk 2211 away from the shell 250 is engaged with the second toothed disk 2221, and the middle part of the inner cavity of the second toothed disk 2221 is fixedly connected to the main body end of the second rotating shaft 222, and a magnet ring 2234 is fixedly installed in the inner cavity of the second toothed disk 2221.
[0106] The resetting elastic member is arranged between the second toothed disc 2221 and the housing 250, the electromagnetic clutch structure pushes the second toothed disc 2221 to separate from the first toothed disc 2211, and the resetting elastic member pushes the second toothed disc 2221 to combine with the first toothed disc 2211. In detail, a telescopic rod 2236 is fixedly installed on one side of the magnet ring 2234 away from the first toothed disc 2211, a support block 2237 is fixedly installed on the other end of the telescopic rod 2236, a spring 2238 is arranged outside the telescopic rod 2236, and both ends of the spring 2238 are fixedly installed on the second toothed disc 2221 and the support block 2237 respectively.
[0107] The second toothed plate 2221 is connected to the housing 250 via a movable bearing 260. Specifically, a connecting block 2239 is fixedly mounted on the side of the supporting block 2237 away from the telescopic rod 2236, and a movable bearing 260 is fixedly sleeved on the side of the connecting block 2239 away from the supporting block 2237. The movable bearing 260 is fixedly mounted in the inner cavity of the housing 250, and is combined with the movable bearing 260 to form a movable bearing.

A balance sensor 241 is fixedly installed in the inner cavity of the shell 250 and directly below the movable bearing 260. The shell 250 and the first toothed disk 2211 are driven to rotate by the first rotating shaft 221. At this time, the first toothed disk 2211 and the second toothed disk 2221 are meshed with each other. The shell 250 can drive the second rotating shaft 222 to rotate during rotation. Driven by the second rotating shaft 222, the collection angle of the collector 230 is changed. During the adaptive adjustment, the balance sensor 241 detects that the angles of the collectors 230 on the two robot arm bodies 100 are deviated, and the balance sensor 241 sends a signal to the power supply 2231, so that the power supply 2231 supplies current to the current valve 2235 through the connecting line 2232. After the electromagnetic ring 2233 is energized, a magnetic force that repels the magnet ring 2234 is generated. Under the action of the repulsive magnetic force, the meshing between the second toothed disk 2221 and the first toothed disk 2211 is disconnected. At this time, the second toothed disk 2221 drives the telescopic rod 2236 to contract, and the spring 22 38 is compressed to generate elastic potential energy. When the second toothed disc 2221 is rotated and adjusted, the second toothed disc 2221 drives the connecting block 2239 to rotate. The movable bearing 260 is provided to make the first toothed disc 2211 relatively stationary when the second toothed disc 2221 rotates. When the angle adjustment is completed, the electromagnetic ring 2233 is powered off. Under the elastic potential energy of the spring 2238, the second toothed disc 2221 is re-engaged with the first rotating shaft 221, so that the first rotating shaft 221 can drive the collection device to rotate, thereby completing the adaptive adjustment of the collector 230 on the robot arm. The present invention adjusts the meshing between the first toothed disc 2211 and the second toothed disc 2221 so that the collection angle of the collection device can be flexibly adjusted, so that the collection devices on the two robot arms can be calibrated, so that the collection devices are maintained in the best acquisition posture, which is conducive to comparing the collection content, avoiding the large difference in the collection angles on the two robot arms due to wear between the components of the collection device during long-term use, making the collection content more accurate, and helping to improve the accuracy of the collected plant information.

Then, the limit plate 2252 is movably connected in the inner cavity of the sleeve 280, and a slide groove 281 is opened in the inner cavity of the sleeve 280. There are two slide grooves 281 and they are respectively matched with the ribs 2253. The side of the sleeve 280 away from the driving end 2251 of the adaptive driving member 225 is fixedly installed on the rotating block 270. A connecting rod 290 is fixedly installed on the upper part of the rotating block 270, and the upper ends of the two connecting rods 290 are respectively fixedly installed with the first collector 231 and the second collector 232.
[0111] During the movement, the second toothed disk 2221 drives the rotating block 270 and the sleeve 280 to move through the second rotating shaft 222, and the limit plate 2252 is used to prevent the connection between the driving end 2251 of the adaptive driving member 225 and the sleeve 280 from being disconnected.

[0112] like Figures 1 to 3 As shown, a fixed block 350 is fixedly installed on the robot arm body 100 and located on the upper part of the slide rail 310, a lifting pneumatic cylinder 320 is fixedly installed on the side of the fixed block 350 away from the slide rail 310, the telescopic end of the lifting pneumatic cylinder 320 is fixedly installed on the main plate 210, a pneumatic cylinder controller 330 is fixedly installed on the upper part of the fixed block 350, and the pressure gauge is located on the upper part of the pneumatic cylinder controller 330, a connecting plate 360 is fixedly installed on the upper end of the robot arm body 100, a fixing frame 3 is fixedly installed on the upper part of the two connecting plates 360, a conveyor belt 2 is arranged at the bottom of the inner cavity of the fixing frame 3, and a base frame 4 is fixedly installed at the bottom of the conveyor belt 2.

The pneumatic cylinder controller 330 detects the air pressure in the lifting pneumatic cylinder 320 through a barometer. When the air pressures in the left and right lifting pneumatic cylinders 320 are different, the air pressure is adjusted by the pneumatic cylinder controller 330 so that the lifting pneumatic cylinder 320 drives the main plate 210 to adjust the position so that the left and right main plates 210 have the same horizontal position, thereby preventing the air pressure in the lifting pneumatic cylinders 320 on the two adaptive mechanical arms 1 from deviating after long-term use, resulting in the position of the telescopic end of the lifting pneumatic cylinder 320 driving the main plate 210 to rise and fall and shifting, which is beneficial to maintaining the symmetry of the positions of the two main plates 210, making the information of the left and right parts of the collected plants more contrasting, and facilitating the staff to conduct better research on the growth conditions and habits of the plants.
[0114] In summary, the method for adjusting the adaptive mechanical arm for collecting plant phenotypic information of the present invention comprises the following steps:
[0115] Set up two adaptive robotic arms 1;
[0116] The balance sensing component 240 senses the offset angle between the second rotation axes 222 of the two adaptive robot arms 1 ; the first rotation axis 221 and the second rotation axis 222 are separated, and the adaptive driving member 225 drives the second rotation axis 222 to rotate the offset angle.
[0117] The air pressure of the lifting air cylinder 320 is adjusted by the air cylinder controller 330 so that the lifting air cylinders 320 of the two adaptive robot arms 1 drive the main plate 210 to the same height.
[0118] After the angle and height are adjusted, the first rotating shaft 221 and the second rotating shaft 222 are connected, the detection driving member 224 drives the first rotating shaft 221, and the collectors 230 of the two adaptive mechanical arms 1 collect plant information.
[0119] The working principle of the present invention is as follows: the plants to be collected are placed on the conveyor belt 2 for transportation. When the plants are transported between the two mechanical arm bodies 100, the conveyor belt 2 stops running, and the pneumatic cylinder controller 330 controls the lifting pneumatic cylinder 320 to start. The telescopic end of the lifting pneumatic cylinder 320 drives the main plate 210 to slide to a suitable position on the slide rail 310. The pneumatic cylinder controller 330 detects the air pressure in the lifting pneumatic cylinder 320 through a pressure gauge. When the air pressures in the left and right lifting pneumatic cylinders 320 are different, the air pressure is adjusted through the pneumatic cylinder controller 330, so that the lifting pneumatic cylinder 320 drives the main plate 210 to adjust the position, so that the left and right main plates 210 have the same horizontal position. The shell 250 is driven to rotate by the first rotating shaft 221. At this time, the first toothed plate 2211 and the second toothed plate 2221 are meshed with each other. The second rotating shaft 222 can be driven to rotate during the rotation of the shell 250. The second rotating shaft 222 drives the rotating block 270 to rotate. The collection angles of the first collector 231 and the second collector 232 are changed through the connection of the connecting rod 290.During the adaptive adjustment, the balance sensor 241 detects the rotation position of the second toothed disk 2221 through the gyroscope set inside it. When it is detected that the angles between the rotation directions of the second toothed disks 2221 on the two robot arm bodies 100 and the gravity direction are different, it indicates that the angles of the collectors 230 on the two robot arm bodies 100 are deviated, and the offset angle is calculated. The balance sensor 241 sends a signal to the power supply 2231, so that the power supply 2231 supplies the current valve 2235 through the connecting line 2232. The current causes the electromagnetic ring 2233 to generate a magnetic force that repels the magnet ring 2234 after being energized. Under the action of the repulsive magnetic force, the meshing between the second toothed disk 2221 and the first toothed disk 2211 is disconnected. At this time, the second toothed disk 2221 drives the telescopic rod 2236 to contract, and the spring 2238 is compressed to generate elastic potential energy. During the movement, the second toothed disk 2221 drives the rotating block 270 and the sleeve 280 to move through the second rotating shaft 222. The stop plate 2252 is used to prevent the output shaft of the adaptive driving member 225 from being in contact with the sleeve. 280 is disconnected, the adaptive driving member 225 is started, and the output end 2251 of the adaptive driving member 225 drives the sleeve 280 to rotate through the engagement of the rib 2253 with the slide slot 281, and the sleeve 280 drives the rotating block 270 to rotate, thereby adjusting the angle of the collector 230, and the rotating block 270 drives the second rotating shaft 222 to rotate, and under the transmission action of the second rotating shaft 222, the second toothed disc 2221 follows the rotation, and the second toothed disc 2221 drives the connecting block 2239 to rotate By setting the movable bearing 260, the first toothed disk 2211 is relatively stationary when the second toothed disk 2221 rotates. The rotation angle of the second toothed disk 2221 is the same as the offset angle detected by the balance sensor 241. When the angle adjustment is completed, the electromagnetic ring 2233 is powered off. Under the action of the elastic potential energy of the spring 2238, the second toothed disk 2221 is re-engaged, so that the first rotating shaft 221 can drive the collection device to rotate, thereby completing the adaptive adjustment of the collection device on the robot arm body 100.
