Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings, but the explanation is not to the mechanical arm and localization method of the present invention
Constitute any restrictions.
Video system and visible light laser emitter device are installed on the robotic arm according to the following steps first:
The end set of mechanical arm 1 has clamping jaw 4, optionally may also include mechanical arm telescopic rod 10.Video system 2 includes taking the photograph
As head 5, transmission of video mechanism 6 and display 7.Transmission of video mechanism 6 in figure is line transmission system, to simplify structure, depending on
Keeping pouring in transfer mechanism, it is preferable to use wireless transmitting systems.Camera 5 is mounted on mechanical arm 1, the optical path Center axis and machine of camera 5
The Clamping Center line along mechanical arm direction of the clamping jaw of tool arm is coaxial.Camera 5 can both be installed on mechanical arm as shown in Figure 1
Rear portion can also be installed on the front of mechanical arm, and the advantage for being installed on front is, with closer, the shelter of target object distance
It is less, be more convenient for capture and imaging.Visible light laser emitter device 3 is also mounted on mechanical arm 1, but its installation site is located at camera shooting
Other than head optical path Center axis, so that emitted laser can be after camera imaging in display after suitable position generates hot spot
Middle display.Visible light laser emitter device 3 is installed on mechanical arm by the shaft 8 perpendicular to mechanical arm, which can be as needed
It is rotated and is positioned.Visible light laser emitter device 3 is rotated along shaft 8, until the laser that is emitted of visible light laser emitter device 3 with
The crosspoint of the optical path Center axis of the camera is located in the clamping opening of clamping jaw, and the crosspoint is located at object to be held and is clamped
When on the end face of front end afterwards, shaft is positioned.Angle between visible light laser emitter device 3 and camera optical path Center axis
The size of α is related away from the vertical range of camera optical path Center axis to visible light laser emitter device 3, when the distance is certain
When, the size of the angle α determines substantially, it is only necessary to which its front end face determined by the length according to target object is located in clamping opening not
With position be finely adjusted.
In the present invention, it can will be seen that the installation settings of ray laser transmitter is that installation site is adjustable, it as a result, can be as needed
The vertical range being adjusted between visible light laser emitter device and camera optical path Center axis.It, can also will be mechanical in the present invention
Arm is set as telescopic mechanical arm, to carry out the operation that straight line approaches target.Telescopic mechanical arm may be used existing
The various structures that may be implemented in technology, a kind of achievable embodiment are as shown in Fig. 2, telescopic mechanical arm uses liquid
Compression bar telescoping mechanism.As shown in Fig. 2, telescopic mechanical arm is to install telescopic rod 10 additional on the robotic arm.Telescopic rod 10 is by hydraulic pressure
Cylinder 11, hydraulic stem 12, oil inlet and outlet 13 form.
Secondly it operates according to the following steps:
Image captured by camera judges that the approximate location of target object 9, operating robotic arm 1 make target object
On the 5 optical path Center axis of center, that is, camera of display 7.Operating robotic arm 1 is straight along camera optical path Center axis direction
Line moves, and target object 9 is gradually approached, until when target object enters in the clamping opening of clamping jaw, it is seen that ray laser transmitter 3 is emitted
Laser can in the surface of 9 front end of target object generate laser facula;Deviate target object center according to the laser facula
Direction and departure degree, continue adjust mechanical arm position, so that laser facula is located at the center of display 7.Drive clamping jaw
It carries out that the accurate clamping that can be realized to target object 9 is clamped.
