Rotating disk center line 13 overlaps afterwards, and computer 7 will not then send control signal to control cabinet 6, and rotating disk 9 is also without quilt
The driving of servomotor 8 rotates and carries out angle adjustment.
Fig. 3 is referred to, if after the preceding rotating disk horizontal center line 12 in initial position image and rotation in location drawing picture
Rotating disk center line 13 is misaligned afterwards, and in the rear rotating disk center line 13 and initial position image after rotation in location drawing picture
Preceding rotating disk horizontal center line 12 between angle theta be more than 0 ° when, computer 7 by controller 6 control servomotor 8 revolved
Turn, to cause rotating disk 9 to carry out counterclockwise rotates and finally cause the preceding rotating disk horizontal center line of initial position image
12 overlap again with the rear rotating disk center line 13 in location drawing picture after rotation.
Fig. 4 is referred to, if after the preceding rotating disk horizontal center line 12 in initial position image and rotation in location drawing picture
Rotating disk center line 13 is misaligned afterwards, and in the rear rotating disk center line 13 and initial position image after rotation in location drawing picture
Preceding rotating disk horizontal center line 12 between angle theta be less than 0 ° when, computer 7 by controller 6 control servomotor 8 revolved
Turn, to cause rotating disk 9 be rotated clockwise and finally cause the preceding rotating disk horizontal center line of initial position image
12 overlap again with the rear rotating disk center line 13 in location drawing picture after rotation.
Rotating disk 9 is after 180 ° of rotation, the preceding rotating disk horizontal center line 12 in initial position image and position after rotation
Rear rotating disk center line 13 in image overlaps, or is driven such that by servomotor 8 in initial position image
After preceding rotating disk horizontal center line 12 is overlapped again with the rear rotating disk center line 13 in location drawing picture after rotation, laser head 10 is again
The secondary laser that sends carries out follow-up cracking groove processing to another splitter of the big end hole of connecting rod 11.
And after two splitter completion of processing of connecting rod 11, computer 7 controls industrial camera 2 by camera lens 3 again to preceding
Rotating disk horizontal center line 12 is shot, and as second of initial position image, then by servomotor 8 to rotating disk
9 are driven and carry out 180 ° of rotations, so that rotating disk 9 resets, computer 7 controls industrial camera 2 by camera lens 3 to rotating disk
9 top surfaces are shot, and are used as location drawing picture after second of rotation.Computer 7 passes through second of initial position image of contrast
Angle theta between rear rotating disk center line 13 after preceding rotating disk horizontal center line 12 and second of rotation in location drawing picture, and phase
Ground is answered to be driven by controller 6 to servomotor 8 so that rotating disk horizontal center line 12 before second of initial position image
Rear rotating disk center line 13 after being rotated with second in location drawing picture overlaps, to ensure before next connecting rod 11 is processed
