On the premise of knowing the complete structure of the above continuous automatic lens polishing method, a person skilled in the art (industrial control) can design a control system (any one of an industrial personal computer, a single chip microcomputer or a PLC can be used as a controller) matched with the structure of the continuous automatic lens polishing method by relying on the existing knowledge, and details are not repeated herein.
Before the work:
the initial position of the mechanical arm device 7 is far away from the maximum stroke of the lens grinding mechanism, and the mechanical arm is over against the lens clamping mechanism; the opening degree of the manipulator is maximum; the cabin door is opened; the clamping center of the lens clamping mechanism 4 is the same as the center of the manipulator in height; the three sleeves of the rotary worktable 2 correspond to the feeding, discharging, receiving and discharging stations, and the sleeves for feeding and discharging are aligned to the push rod 42. The lens tray 40 of the push rod 42 is below the rotary platform.
Firstly, a cylinder of piled lens blanks is put in from the upper part of a sleeve of a material-putting and receiving station.
When in work:
firstly, a control system is started, the rotary workbench 2 starts to work, the hollow rotary transmission device 11 drives the tray 9 to rotate 120 degrees clockwise, the sleeve for placing the lens is converted to the feeding station from the receiving and discharging station, the sleeve for the feeding station is converted to the sleeve for the discharging station, and the sleeve for the discharging station is converted to the sleeve for receiving and discharging.
After the station conversion of the rotary workbench is completed, the other group of lenses can be placed into the sleeve for receiving and discharging materials. The electromagnetic clutch 50 connected with the left worm gear case 49 is disconnected when power is lost, the electromagnetic clutch 50 connected with the right worm gear case 43 is connected with the right worm gear case 43 and the right-angle left-right reverse output gear case 48 when power is turned on, and the motor drives the lens tray 40 of the blanking station to move upwards to a workpiece thickness below the upper surface of the sleeve 8. The electromagnetic clutch 50 connected with the right worm gear case 43 is disconnected when power is lost, the electromagnetic clutch 50 connected with the left worm gear case 49 is connected with the left worm gear case 49 and the right-angle left-right reverse output gear case 48 when power is on, and the motor drives the lens tray 40 of the feeding station to move the lens blanks upwards to a workpiece thickness above the upper surface of the sleeve.
The second cylinder 38 pushes the suction cup 35 to move down to suck the lens exposed from the feeding station, and the second cylinder 38 drives the lens blank to be processed to move up to the position to be clamped.
The robot arm arrangement 7 of the rotary platform 2 then starts working. After a steering cylinder 30 of the mechanical arm device 7 turns anticlockwise to a manipulator alignment feeding station, a rodless cylinder 27 pushes the manipulator to move forwards to the center of the V-shaped groove rubber plate 15 to align with the center of the lens blank; the cylinder 22 pushes the connecting rod structure type grabbing manipulator to close and grab the lens blanks; the rodless cylinder 27 pushes the manipulator to return to the maximum stroke position, namely the initial position, and the steering cylinder 30 at the bottom of the manipulator device 7 drives the manipulator to face the lens clamping mechanism; the rotary cylinder 24 drives the manipulator to rotate 90 degrees, and the horizontal state is changed into a vertical state; the rodless cylinder 27 pushes the robot to advance until the lens blank center coincides with the clamping center of the clamping mechanism. The third cylinder 75 pushes the chuck 70 and sucks the lens blank with air, and the chuck 70 and the left chuck 69 clamp the lens blank. The cylinder 22 drives the manipulator to open, and the rodless cylinder 27 drives the manipulator to return to the maximum stroke position, namely the initial position. Closing the cabin door; a second motor 104 in the lens grinding mechanism 6 drives a grinding wheel to rotate at a high speed through a belt 112, motors 95 in the X direction and the Y direction in a cross sliding table mechanism feeding mechanism 5 drive a screw rod 87 to rotate, the screw rod 87 drives a support frame 93 in the X direction and the Y direction to move linearly, the support frame 93 drives a lens clamping mechanism 4 to a processing position of the lens grinding mechanism 6 to select the grinding wheel for processing according to a lens blank material, the motor in the lens clamping mechanism 4 drives a lens blank to adjust the angle, and the cross sliding table mechanism feeding mechanism 5 drives the lens clamping mechanism 4 to move linearly in the Y direction, so that different shapes of lenses are processed; after the lens is machined, the cross sliding table mechanism feeding mechanism 5 drives the lens clamping mechanism 4 to return to the original position, namely the central height of the lens clamping mechanism 4 is consistent with the central height of the robot hand. The hatch door is opened. The rodless cylinder 27 of the mechanical arm device 7 pushes the manipulator to advance until the center of the V-shaped groove rubber plate 15 coincides with the center of the lens, and the cylinder 22 pushes the manipulator to close to grasp the finished lens. The chuck suction cup 70 in the lens clamping mechanism 4 is deflated to release the finished lens, the cylinder 75 pulls the chuck suction cup 70, the chuck suction cup 70 and the left chuck 69 release the finished lens, and the chuck suction cup 70 returns to the original position. The rodless cylinder 27 pushes the manipulator to return to the initial position, and at the moment, the rotary cylinder 24 drives the manipulator to rotate, so that the rotation is converted from vertical to horizontal; a steering cylinder 30 of the mechanical arm device 7 turns clockwise until the manipulator is opposite to the blanking station, and a rodless cylinder 27 pushes the manipulator to move forward until the center of the finished lens product is coincided with the center of the sleeve; the cylinder 22 drives the manipulator to open to the maximum, and the finished lens is placed on the lens tray. The rodless cylinder 27 brings the robot arm back to the maximum stroke position, i.e., the initial position. The steering cylinder 30 drives the mechanical arm to rotate clockwise to a position before machining. Meanwhile, the electromagnetic clutch 50 connected with the left worm gear case 49 is electrically closed to connect the left worm gear case 49 with the right-angle left-right reverse output gear case 48, the electromagnetic clutch 50 connected with the right worm gear case 43 is electrically closed to connect the right worm gear case 43 with the right-angle left-right reverse output gear case 48, the motor is started to move the lens blanks on the feeding station upwards by one workpiece position, and the lens finished products on the blanking station downwards by one workpiece position. And finishing the processing of the single lens.
And secondly, the automatic processing of a group of lenses can be completed by repeating the operations of feeding, clamping, processing and blanking.
Finally, when a group of lenses are machined, the feeding station sleeve is empty, the blanking station sleeve is filled with finished lenses, the electromagnetic clutch 50 connected with the right worm gear box 43 is disconnected in a power-off mode, the electromagnetic clutch 50 connected with the left worm gear box 49 is closed in a power-on mode, the right worm gear box 49 is connected with the right-angle left-right reverse output gear box 48, and the motor drives the lens tray 40 of the blanking station to move downwards to 10mm below the rotary platform tray. The electromagnetic clutch 50 connected with the left worm gear case 49 is disconnected when power is lost, the electromagnetic clutch 50 connected with the right worm gear case 43 is connected with the right worm gear case 43 and the right-angle left-right reverse output gear case 48 when power is turned on, and the motor drives the lens tray 40 of the blanking station to move downwards to 10cm below the rotary platform tray. The hollow rotary transmission device 11 of the rotary platform 2 drives the tray 9 to rotate 120 degrees clockwise, at this time, the original material receiving and discharging sleeve filled with the lens blanks becomes a material loading station, the empty sleeve of the original material loading station becomes a material discharging station, and the sleeve filled with finished products of the original material discharging station becomes a material receiving and discharging station. At this time, a group of lens finished products can be manually taken down and then a group of lens blanks to be processed are put in.
The above processes are repeated to realize the continuous automatic processing of the lens.
By adopting the continuous automatic lens polishing method, the working efficiency of feeding, clamping and discharging the lenses is greatly improved.
