Mobile phone light guide panel is positioned in rotation sample platform and support plate, the machine is opened under the control of preset control system
Beginning work pushes third sliding block to be slided to the first localization machine of drive along the third sliding rail by the push rod of the first flat-removing air cyclinder
Structure is close to support plate；Four-slider is pushed to slide to drive described the along the 4th sliding rail by the push rod of second flat-removing air cyclinder
Two detent mechanisms are realized light guide plate and are positioned, and light guide plate is adsorbed in support plate by negative-pressure vacuum system, later close to support plate
First detent mechanism and the second detent mechanism return at third machined surface, be set to third machined surface at detent mechanism with
Third work stage translation, later under the driving of X axis driving mechanism, third workbench moves to polishing station, polishing motor
Driving polishing blade one machined surface of light guide plate is polished, later X axis driving mechanism, Y-axis driving mechanism driving and
Light guide plate is rotated by 90 ° under the action of rotating drive mechanism, is realized successively to the second machined surface of light guide plate and third processing
The polishing in face, this process burnishing device is fixed, need not translate or lift, and translational drive mechanism drives material fetching mechanism later
X axis translates, and take-off assembly upper and lower translation is driven by the lifting cylinder, and take-off assembly rotation is driven by rotary cylinder,
Full-automation, intelligent polishing to mobile phone light guide panel are realized in rewinding；
Wherein, the debugging process of positioning device is that mobile phone light guide panel is placed and the first flat-removing air cyclinder and second translates gas
After cylinder driving in place, this first detent mechanism is adjusted by first base later and is located at the general location of equipment, then pulls positioning
Then the position of bar is passed through the threaded hole of the first fixed block and is tightened and locating rod is fixed on the first fixed block, most by bolt
The first fixed block and the first sliding block is pushed to be translated along the first sliding rail to drive locating rod to lean on by the knob of turn micrometer afterwards
Nearly workpiece, and will be moved after the first fixed block and the first sliding block to drive locating rod far from workpiece by tension spring；Is adjusted later
Two detent mechanisms are located at the general location of equipment, push the second fixed block and the second sliding block to be slided along second by turn fine-tuning nut
Rail translation is to drive locating piece workpiece close with positioning Bearing support, at this point, the outer ring of positioning bearing is butted on side and the limit of workpiece
Position boss extends to the upper surface of workpiece, and the rotation by positioning bearing rubs the sliding between the first detent mechanism and workpiece
Wiping is converted into rolling friction, reduces frictional force, i.e. the opposite two sides of workpiece are mended by an origin reference location mechanism and a buffer-type
It repays detent mechanism and realizes precise positioning.
