Abstract
The invention discloses the position calibration method of robot arm of the present invention, including the following steps carried out successively：Using marking pen is in the centrally disposed origin of blank sheet of paper and set up coordinate system, test point is randomly provided around origin, the coordinate of each test point is measured；The coordinate system set up in step A is matched with the Control coordinate system of robotic arm；A marking pen is installed into robotic arm end, the coordinate of the test point set in step A is inputted in the control system of robotic arm simultaneously, control machine arm is moved to each test point and the mark point to be formed and be matched one by one with each test point of being marked with the marking pen of robotic arm end successively；Each test point and its mark of matching point are identified using image identification system, the operating error of computing machine arm is modified.It is an advantage of the invention that：It is simple to operate, test can be completed in factory, it is not necessary to return factory；Need not be by other equipment, testing cost is low.
Description
Technical field
The present invention relates to a kind of robot arm control method, and in particular to the position calibration method of robot arm.
Background technology
Mechanical arm is the automated machine device that most broad practice is obtained in robot technical field, in industry system
Make, therapeutic treatment, entertainment service, military affairs, the field such as semiconductor manufacturing and space probation can see its figure.Although it
Form have nothing in common with each other, but they have one it is common the characteristics of, can exactly receive instruction, be precisely positioned to three-dimensional space
Between on certain point carry out operation.
Existing robot arm calibration needs to be equipped with the more calibrator (-ter) unit of specialty or return factory to be calibrated mostly, into
This is higher, and calibration is inconvenient.
The content of the invention
The technical problems to be solved by the invention are that existing robot arm calibration needs to be equipped with more specialty mostly
Calibrator (-ter) unit returns factory and calibrated, and cost is higher, and calibration is inconvenient, it is therefore intended that provide the position correction of robot arm
Method, the existing robot arm calibration of solution needs to be equipped with the more calibrator (-ter) unit of specialty or return factory to be calibrated mostly,
Cost is higher, the problem of calibration is inconvenient.
The present invention is achieved through the following technical solutions：
The position calibration method of robot arm, including blank sheet of paper and robotic arm, including the following steps carried out successively：
A, using marking pen is in the centrally disposed origin of blank sheet of paper and set up coordinate system, test point is randomly provided around origin,
Measure the coordinate of each test point；
B, the coordinate system set up in step A matched with the Control coordinate system of robotic arm；
C, robotic arm end installed into a marking pen, while the coordinate of the test point set in step A is inputted into machine
In the control system of device arm, control machine arm is moved to each test point and made of the marking pen of robotic arm end successively
The mark point that mark formation is matched one by one with each test point；
D, using image identification system each test point and its mark of matching point are identified, the work of computing machine arm
It is modified as error.
The quantity of test point is at least 3 and no more than 10 in the step A, and the test point is respectively positioned on different straight lines
On.Using the mobile precision of the effective test machine arm all directions of test point energy of above-mentioned distribution.
Marking pen in the step A uses different colors from the marking pen in step C installed in robotic arm end.
Be conducive to the identification of image identification system in step D using different colors.
The present invention compared with prior art, has the following advantages and advantages：
1st, the position calibration method of robot arm of the present invention, simple to operate, and test can be completed in factory, it is not necessary to
Return factory；
2nd, the position calibration method of robot arm of the present invention, it is not necessary to which, by other equipment, testing cost is low.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment, to present invention work
Further to describe in detail, exemplary embodiment and its explanation of the invention is only used for explaining the present invention, is not intended as to this
The restriction of invention.
Embodiment
The position calibration method of robot arm of the present invention, including blank sheet of paper and robotic arm, including carry out successively it is following
Step：
A, using black marking pen is in the centrally disposed origin of blank sheet of paper and set up coordinate system, test is randomly provided around origin
Point, measures the coordinate of each test point；The quantity of the test point is 6, and the test point is respectively positioned on different straight lines.Using
The mobile precision of the effective test machine arm all directions of test point energy of above-mentioned distribution.
B, the coordinate system set up in step A matched with the Control coordinate system of robotic arm；
C, robotic arm end is installed to red symbol pen, while the coordinate of the test point set in step A is defeated
In the control system for entering robotic arm, control machine arm is moved to each test point and with the mark of robotic arm end successively
Pen is marked the mark point to be formed and be matched one by one with each test point；
D, using image identification system each test point and its mark of matching point are identified, the work of computing machine arm
It is modified as error.
Above-described embodiment, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail, should be understood that the embodiment that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc. all should be included
Within protection scope of the present invention.
