the closed type workbench 2 is used for closing the whole working area to avoid the escape of crystal dust everywhere, the sucker fixing frame 3 is used for fixedly installing the vacuum sucker 4, the vacuum sucker 4 generates vacuum suction through the vacuum generator 5, thereby firmly sucking the special-shaped glass 1 placed on the vacuum chuck 4, the electric turntable 6 is used for driving the chuck fixing frame 3, the vacuum chuck 4 drives the special-shaped glass 1 to rotate on the horizontal plane, the measuring mechanism 7 measures the distance between the edge of the special-shaped glass 1 and the axis of the electric turntable 6 while the special-shaped glass 1 rotates, and sends the data to the controller, the controller sends the data to the self-adaptive polishing mechanism 8, the self-adaptive polishing mechanism 8 automatically adjusts the distance between the working end of the self-adaptive polishing mechanism and the axis of the electric turntable 6, the working surface of the self-adaptive polishing mechanism 8 is always attached to the edge of the special-shaped glass 1, so that the device can fully automatically polish the special-shaped glass in any shape.
Firstly, the worker unscrews the vacuum suction cups 4, then adjusts the positions of the vacuum suction cups 4 in the oval holes 3c2, and screws the vacuum suction cups 4 when the space between the vacuum suction cups 4 is suitable for the size of the special-shaped glass 1, so that the vacuum suction cups 4 are fixed on the suction cup fixing frame 3 and cannot move;
then, the worker opens the opening at the top of the frame 2a through the top cover 2c, after the worker opens the top cover 2c, the worker takes up the stay bar 2e to rotate around the universal joint 2d, and the free end of the stay bar 2e supports the top cover 2c, so that the top cover 2c is kept in an open state, and then the worker places the shaped glass 1 on the vacuum chuck 4;
then, the worker closes the opening at the top of the frame 2a through the top cover 2c, so that crystal dust generated during edge polishing of the special-shaped glass 1 is prevented from escaping everywhere;
then, the vacuum pump 5a works to pump air, the air inside the vacuum chuck 4 starts from the first connecting pipe 4b2, sequentially passes through the air collecting and exhausting pipe 5b and the rotary airtight pipe 5d through the gas pipeline 5c to reach the working end of the vacuum pump 5a, and is pumped out by the vacuum pump 5a and exhausted to the atmosphere, so that the vacuum chuck 4 firmly adsorbs the shaped glass 1 on the top surface thereof;
then the electric turntable 6 is started to drive the sucker fixing frame 3 to rotate, the sucker fixing frame 3 drives the shaped glass 1 to rotate, at the moment, the sucker fixing frame 3 drives the gas gathering exhaust 5b to rotate together, the gas gathering exhaust 5b and the rotary airtight pipe 5d rotate relatively, namely, the third annular flange 5d1 rotates inside the second connecting pipe 5b2, and the third annular flange 5d1 rotates relative to the second connecting pipe 5b2, and meanwhile, the air tightness is ensured through the sealing ring 5e, so that the leakage is avoided;
when the special-shaped glass 1 rotates, the rotating wheel 7a always abuts against the edge of the special-shaped glass 1 through the resilience force of the gas spring 7c, the rotating wheel 7a moves along with the change of the distance between the edge of the special-shaped glass 1 and the axis of the electric turntable 6, the displacement sensor 7d obtains the moving distance of the rotating wheel 7a through the movement of the measuring wheel carrier 7b, the displacement sensor 7d sends an electric signal to the controller, the controller calculates the distance between the edge of the special-shaped glass 1 and the axis of the electric turntable 6 and then sends the distance to the linear driver 8d to adjust the distance between the servo motor 8a and the axis of the electric turntable 6 according to the signal sent by the controller, so that the servo motor 8a drives the grinding wheel 8c to move, and the working face of the grinding wheel 8c is always attached.
