The instruction that industrial robot performing a programme compiling system is transmitted and come, realizes the execution of working procedure.
Further, described attitude information comprise joint arm perform process actions time moving coordinate information, rotational angle information, velocity information.
Further, described data collecting system comprises the sensor arranged on joint arm.
A kind of off-line programing teaching robot teaching method, is characterized in that, comprise teaching robot's (including but not limited to above-mentioned teaching robot), perform following steps:
Step S10, teaching robot are carried out operation task by manual drive and then drive joint arm to move, and meanwhile, the institute's position sensor being arranged on joint arm records attitude information corresponding separately on each joint arm respectively;
The attitude information recorded in step S10 is sent to host computer by communication bus by step S20, institute's position sensor;
Step S30, described host computer carry out processing to the attitude information received and compile, and in software after spotting robot, generate robot execution of programs of instructions;
The robot execution of programs of instructions generated in step S30 is sent in the robot of production line by step S40, described host computer.
Further, in step S20, the movable information of the joint arm recorded in step S10 is sent to host computer data processing software by communication bus by institute's position sensor, and movable information is carried out control program by generating heterogeneous robot after algorithm process for download by data processing software.
Further, in step S20, the angle information of each for joint arm revolute pair is sent to host computer by RS232, RS485 or CAN by institute's position sensor.
Further, in above-mentioned teaching robot and teaching method, described joint arm adopts the unpowered joint arm of aluminum alloy materials manufacture.
Further, host computer its be connected with the position sensor in the revolute pair of each joint arm by communication bus, and send broadcast and request signal to position sensor, and the attitude information of institute's position sensor transmission can be received, and then use special-purpose software to process to the attitude information received, generate target robot execution of programs of instructions; Robot its be connected with host computer by communication bus, the robot execution of programs of instructions that host computer transmits can be received, and the process actions of teaching robot can be reappeared according to robot execution of programs of instructions at production line.
Robot teaching system: operating personnel or workman are based on joint arm, realize original operative's instrument to finish the work task, workman completes operation tool in whole task process, and instrument is arranged on joint arm, complete in certain operation work in teaching, thus drive joint arm motion; The structure of this joint arm teaching system is light material, and with gravity-compensated device and damping system, forms unpowered joint arm system together, greatly reduces the teaching difficulty of operating personnel, and keeps the flexibility of operation.
Data collecting system: realize the movement to the kinematic pair of each correspondence of joint arm unpowered in teaching system and rotation information collection (comprising position, speed and acceleration information in the information moving and rotate), also comprise the movable information (start and stop of such as executing means, motion of turntable etc.) of servicing unit simultaneously.
Special purpose robot's program compilation system: this system is made up of host computer and relevant special-purpose software, host computer receives the movement of the kinematic pair of each correspondence of unpowered joint arm that data collecting system transmits, the movable information of rotation information and servicing unit, and input in special purpose robot's program compilation software, software is according to the structural parameters of the robot of different structure, in conjunction with the demarcation information between joint arm and target robot, the information gathered is recompilated and generates corresponding robot application program, thus realize the utility model can for various heterogeneous robot working procedure Automatic Optimal and programmed function.
The principle of its data processing is as follows:
(1) the joint rotation angle information obtained during teaching operation just can obtain the track of joint arm end executing means after forward kinematics solution.
(2) track obtains the kinematic parameter of the end executing means of target robot through Inverse Kinematics Solution.These parameters can be compiled into tool hand fortune target robot Motor execution code.
Specifically, true or Virtual Demonstration is carried out by teaching mechanism, simultaneously, data collecting system collects associated joint arm movable information, input host computer, by host computer special-purpose software in conjunction with the demarcation information between joint arm and target robot, calculate each movable joint arm motion control information of used robot, generate control program.
Concrete actualizing technology flow process:
(1) first operator carries out certain planning to machining path, because the track of teaching will determine the operating path of target robot;
(2) operating personnel drive the instrument on teaching joint arm to process workpiece.Joint angles on each joint of data collecting system real time record teaching joint arm, and change into the position of joint motions, speed and angular speed, also can record the movable information (start and stop of such as instrument, the motion of turntable etc.) of other servicing unit simultaneously;
(3) the joint rotation angle information obtained during teaching operation just can obtain the track of joint arm end executing means after forward kinematics solution, and track obtains the kinematic parameter of each kinematic pair of target robot or the kinematic parameter of end executing means through Inverse Kinematics Solution.These parameters can be compiled into tool hand fortune target robot Motor execution code.
When target robot and joint arm isomorphism same parameter, do not need, through positive inverse kinematics mapping relations, to obtain the kinematic parameter of the joint motions pair of target robot;
When the coordinate system of the coordinate system of joint arm base and target robot base is operationally inconsistent, the coordinate conversion relation between joint arm and target robot should be considered, by the coordinate system of joint arm base and the coordinate system of target robot base operationally consistent, then the generation of robot program between joint arm and target robot is simplified through suitable demarcation, the data of the tool tip of namely joint collection, compound is simply demarcated just can directly as the track of target robot motion, simplify the generation of target robot motor program, avoid complicated data processing.
(4) in conjunction with the structural parameters of industry mechanical arm, teaching movement locus is converted automatically to the motor program of manipulator, and send to industry mechanical arm by Ethernet.
(5) industry mechanical arm reproduces teaching track, realizes manipulator glaze spraying.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
