The working process of the laser sensing intelligent welding robot 100 is briefly described as follows:
when the 3D laser scanner 41 needs to be calibrated, the first driving unit 44 and the second driving unit 45 cooperate to move the 3D laser scanner 41 to the calibration block 42, and control the 3D laser scanner 41 to scan the calibration block 42 to obtain the position information and each standard size parameter information of the calibration block 42; then, the control center judges whether the position and the scanning precision of the 3D laser scanner 41 are accurate or not according to the set calibration program, the stored standard size parameters of the calibration block 42, and the absolute position information of the calibration block 42 in the world coordinates, and when the position and/or the scanning precision of the 3D laser scanner 41 are not accurate and can be calibrated, calibrates the position and/or the scanning precision of the 3D laser scanner 41, and generates a new configuration table and stores the new configuration table in the control center; further, when the configuration table is updated, the control center calculates the work coordinates of the welding gun 51 on the welding robot 5 with the new configuration table, thereby making the consistency of the associated data between the 3D laser scanner 41 and the welding robot 5.
When the position of the welding torch 51 needs to be calibrated, the third driving unit 53 and the fourth driving unit 54 cooperate to move the welding torch 51 to the welding torch calibration unit 8, and detect the position of the welding torch 51 in the first direction X, the second direction Y, and the height direction Z, respectively, in combination with the third correlation type photoelectric sensor 81 and the fourth photoelectric sensor, so as to determine whether the position of the welding torch 51 is accurate. When the position of the welding gun 51 in the first direction X is inaccurate and can be calibrated, the control center calibrates the position of the welding gun 51, and simultaneously generates a new configuration table to be stored in the control center; when the position of the welding gun 51 in the second direction Y is inaccurate and can be calibrated, the control center calibrates the position of the welding gun 51, and generates a new configuration table and stores the new configuration table in the control center; when the position of the welding gun 51 in the height direction Z is inaccurate and can be calibrated, the control center calibrates the position of the welding gun 51, and simultaneously generates a new configuration table to be stored in the control center; in addition, the control center calibrates the welding angle of the welding gun 51 according to a set calibration program, and when the welding angle is inaccurate and can be calibrated, the control center calibrates the welding angle of the welding gun 51 and generates a new configuration table to be stored in the control center. When any of the above detections by the welding gun 51 is abnormal, the control center performs error reporting processing.
When the aluminum template 10 needs to be welded, a first aluminum template 10 is placed on the first aluminum template fixture 2, at this time, the control center detects whether the aluminum template 10 is placed on the aluminum template fixture 2 through the first paired photoelectric sensors 25 on the aluminum template fixture 2, detects whether the placement position of the aluminum template 10 is accurate through the second paired photoelectric sensors 26, and detects the length of the aluminum template 10 through the distance measuring sensor 27. When the aluminum template 10 is placed on the aluminum template fixture 2 and the placing position of the aluminum template 10 is accurate, the pressing unit 22 of the aluminum template fixture 2 presses the aluminum template 10, so that the copper bar 23 is in contact with the aluminum template 10. Meanwhile, the control center controls the first driving device 3 to move the aluminum mold plate holder 2 to the first vision system 4 according to the detected length of the aluminum mold plate 10, and positions the aluminum mold plate holder 2.
Then, the control center controls and coordinates the operations of the first driving device 3 and the first vision system 4, so that the 3D laser scanner 41 of the vision system 4 scans the first aluminum mold plate 10 to acquire welding data required by the first welding robot 5.
Then, the control center controls and coordinates the first driving device 3 and the operation of at least one first welding robot 5 so that the welding torch 51 of the first welding robot 5 performs welding processing on the aluminum mold 10 on the first aluminum mold clamp 2. Meanwhile, the control center obtains whether the aluminum template 10 on the second aluminum template clamp 2 is welded, if so, a new aluminum template 10 is placed on the second aluminum template clamp 2, and if not, the control center waits for the aluminum template 10 on the second aluminum template clamp 2 to be welded. The step of placing a new aluminum mold plate 10 on the second aluminum mold plate holder 2 is the same as the step of placing a new aluminum mold plate 10 on the first aluminum mold plate holder 2, and therefore, the description thereof will not be repeated.
During the welding process of the aluminum template 10, the control center adjusts the number of the welding robots 5 required to participate simultaneously according to the scanning result of the vision system 4. After the welding of the aluminum template 10 is completed, the control center controls the driving device 3 to transfer the aluminum template clamp 2 loaded with the aluminum template 10 to the loading position, and controls the pressing unit 22 of the aluminum template clamp 2 to release the pressing of the aluminum template 10, so as to replace the aluminum template clamp 2 with a new aluminum template 10 to be processed.
In conclusion, through the structural design of the intelligent laser sensing welding robot, when the vision system scans the aluminum template on one aluminum template clamp, the welding robot can weld the aluminum template on the other aluminum template clamp, so that the no-load waiting time of the welding robot is eliminated or reduced, the welding efficiency of the intelligent laser sensing welding robot is effectively improved, and the intelligent laser sensing welding robot can meet the requirement of mass processing.
