[0064] In specific implementation, before unloading, the two lifting mechanisms are located at the top and bottom of the bidirectional screw 18. When in use, the unprocessed stacked glass can be placed on the lifting mechanism on the left, and the processed glass during the processing is placed on the lifting mechanism on the right. At the same time, when the robot 7 takes the glass from the lifting mechanism on the left and takes the glass from the positioning platform 11 and places it on the lifting mechanism on the right, the servo motor 17 is reversed under the control of the external controller, so that the bidirectional screw 18 rotates and drives the two lifting mechanisms to approach each other, so that the unprocessed glass moves upward one station on the first unloading table 9, and the processed glass moves downward one station on the second unloading table 10.

[0065] Example 4

[0069] When the CNC platform 12 is processing glass, the manipulator 7 sucks a piece of unprocessed glass from the first unloading table 9 and places it on the positioning table 11, and then the telescopic suction handle 8 on the left side sucks and retracts the glass on the positioning table 11, and then the telescopic suction handle 8 moves along the suction handle running track 3 to the CNC processing body 2 area. After the glass on the CNC platform 12 is processed, the telescopic suction handle 8 on the right side that has not sucked the glass is extended to suck and retract the processed glass, and then the telescopic suction handle 8 on the left side places the unprocessed glass on the CNC processing platform 12 and retracts, and then the telescopic suction handle 8 moves along the suction handle running track 3 back to the top of the loading and unloading table 4, and the processed glass is placed on the positioning table 11, and then the manipulator 7 takes the processed glass from the positioning table 11 and places it on the second unloading table 10;
