Introduce again the workflow of whole system below.Be divided into and unload battery and two parts of packed battery.
(1) unload battery part:
A, by the little CCD camera 4 on handgrip, the battery hole seeing through in the middle of undercarriage fixed head carries out image processing, whether scanning has small-sized many rotor wing unmanned aerial vehicles to change on platform at battery ground.
If B has small-sized many rotor wing unmanned aerial vehicles on platform, the task of changing battery is described, send instruction to the motor 3.4 under mark plate by control, carry out the fixing shrinkage operation of fixing handgrip 3.3 to small-sized many rotor wing unmanned aerial vehicles undercarriage.
C, execute after pinned task, handgrip is carried out rising along slide rail 7 of task by motor 10, and when handgrip arrives the Battery Card groove location of small-sized many rotor wing unmanned aerial vehicles, handgrip is carried out self-contained battery operation.
D, handgrip fix after battery, by the control of the servomotor 3 to handgrip bottom, realize the rotation operation of handgrip to battery.
E, after executing 90 degree battery rotaries operations, battery and change hands just in time can be in the hollow out of draw-in groove bottom out.
F, finally control and realize elevating lever landing operation by motor 10, when battery down just in time makes battery drop on the battery case of rotating disk through control hole.Finally realize the unloading operation of battery.
(2) packed battery part:
A, after having battery on rotating disk, by controlling the motor 4.3 below rotating disk, realize the rotation of rotating disk, namely make the battery rotary of deposit to the corresponding manipulable position of elevating lever, what here we arranged is 30 degree rotations, then scan by the CCD camera 4 in the middle of elevating lever, whether have the battery rotary of deposit to come, if do not proceed 30 degree rotations.
B, when detecting after battery, by the control to motor 10, elevating lever is raise along slide rail 7, change hands the reserve cell of fixing on rotating disk.
C, elevating lever rise, until the battery case position under small-sized many rotor wing unmanned aerial vehicles.
The D part that D, the face of catching up with unload is the same, by controlling the servomotor 3 under handgrip, realizes the rotation to battery.
E, after having carried out the rotations of 90 degree, battery fixed head above battery case 1.4 can be by spring 1.5, makes the plug on jack and small-sized many rotor wing unmanned aerial vehicles of battery realize blindmate, carries out the power supply to unmanned plane.
F, elevating lever are controlled by motor 10 after executing these operations, are retracted into origin-location, send unlock command then to the motor below mark, realize the release to undercarriage.
The final automatically replacing battery operation that has just realized small-sized many rotor wing unmanned aerial vehicles.
The present invention adopts rotating disc type battery reserve storehouse, once can carry out at most the replacing of 5 primary cells, and the present invention adopts blindmate formula battery efficiency quick and easy for installation high; Device of the present invention has been realized automatic loading and the unloading of small-sized many rotor wing unmanned aerial vehicles battery, thereby realizes the automatic replacing of small-sized many rotor wing unmanned aerial vehicles battery.
