Understandable, this controller 371 can also comprise displacement presetting module, for setting preset displacement amount according to different grinding work pieces; Preset displacement amount comprises preset level displacement, preset vertical displacement and default swing offset amount etc.Corresponding, the movement instruction that this controller 371 generates according to preset displacement amount can comprise rotary motion instruction, to control the action of emery wheel feeding whirligig 32, make emery wheel feeding whirligig 32 move to suitable position, workpiece is processed at any angle.
Operation principle below in conjunction with the control method of this control system is described further the horizontal four limit edge polisher control systems of the present invention:
First, setting preset displacement amount, such as, according to the demand of different workpiece, the displacements such as setting level, vertical, selection.
Then, utilize the algorithm preset according to preset displacement amount, calculate and generate movement instruction, and be sent to servo-driver.Drive servomotor to rotate by servo-driver according to movement instruction and drive emery wheel feeding, and detect the current kinetic displacement amount of servomotor by encoder; Meanwhile, the real-time grinding and feeding amount of emery wheel is detected by emery wheel feeding checkout gear.Compare with preset displacement amount according to current kinetic displacement amount and real-time grinding and feeding amount, to adjust the Bit andits control amount of servomotor, realize adjusting in real time, thus realize precisely controlling to the feeding of emery wheel.
Concrete: (1) horizontal transfer portion: controller 371 is according to the horizontal feed amount preset, the algorithm preset is adopted to calculate horizontal movement instruction, horizontal servo motor 339 rotates according to horizontal movement instruction, thus drives emery wheel feed arrangement 33 to do horizontal motion.
Now, real-time for the present level moving displacement amount of present level servomotor 339 is fed back to horizontal movement means 373 and controller 371 by level code device 375.Jointly judged by controller 371 and horizontal movement means 373, arrive the horizontal feed amount position of presetting with level of control servomotor 339.
What detect due to level code device 375 is the displacement of horizontal servo motor 339, is not the exact shift of emery wheel, therefore, needs the Real-time Water plain grinding in conjunction with horizontal detecting sensor sensing to cut amount of feeding correction.That is, in glass 40 grinding process, the horizontal detection sensor of emery wheel feeding checkout gear 35 detects the real-time grinding and feeding amount of emery wheel 36 horizontal direction in real time, and by real-time grinding and feeding amount Real-time Feedback to controller 371, cut the amount of feeding by controller 371 according to the Real-time Water plain grinding fed back, present level moving displacement amount compares adjust in real time with the horizontal feed amount preset, thus reach high accuracy and control.
(2) vertical transfer portion: controller 371 is according to the vertical feed amount preset, the algorithm preset is adopted to calculate the instruction that moves both vertically, vertical servo motor 316 rotates according to the instruction that moves both vertically, thus drives emery wheel vertical-adjustment device 31 to do movement in vertical direction.
Now, real-time the feeding back to of current vertical moving displacement amount of current vertical servomotor 316 moves both vertically driver 372 and controller 371 by vertical code device 374.Jointly judged by controller 371 and the driver 372 that moves both vertically, arrive the vertical feed amount position of presetting to control vertical servo motor 316.
What detect due to vertical code device 374 is the displacement of vertical servo motor 316, is not the exact shift of emery wheel, therefore, needs the real-time perpendicular grinding amount of feeding in conjunction with vertical detection sensor sensing to revise.That is, in glass 40 grinding process, the vertical detection sensor of emery wheel feeding checkout gear 35 detects the real-time grinding and feeding amount of emery wheel 36 vertical direction in real time, and by real-time grinding and feeding amount Real-time Feedback to controller 371, compared and adjust in real time according to the real-time perpendicular grinding amount of feeding fed back, current vertical moving displacement amount with the vertical feed amount preset by controller 371, thus reach high accuracy and control.
(3) part in rotary moving: controller 371 is by presetting swing offset amount, generate rotary motion instruction, then export emery wheel feeding whirligig 32 to, by the action of emery wheel feeding whirligig 32, drive emery wheel adjustment set angle, thus the grinding of different angles can be realized.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.
