[0040] In this embodiment, the flip driving device 4 and the conveying motor device 302 both include a motor and a reducer drivingly connected to the motor shaft.

[0041] When the glass turning table is working, the first conveying wheel device 31 conveys the glass workpiece 100 processed in the previous process to the top of the first turning support structure. When the glass workpiece 100 is in place, the turning drive device 4 drives the workpiece turning frame 5 to rotate 90° counterclockwise, so that the first turning support structure holds up the glass workpiece 100 and rotates 90° counterclockwise. During the process of the glass workpiece 100 rotating 90° counterclockwise, the glass workpiece 100 is slowly transferred from the first turning support structure to the second turning support structure and supported by the second turning support structure until the top of the turning support member 55 of the second turning support structure is lower than the top of the conveying roller 305 of the second conveying wheel device 32. Then, the second turning support structure holds the glass workpiece 100 is placed on the second conveying wheel device 32 to complete the 90° flipping action of the glass workpiece 100; then the front-back moving mechanism 8 drives the flipping driving device 4 and the workpiece flipping frame 5 to move forward, so that the flipping supporting member 55 of the workpiece flipping frame 5 withdraws from between the conveying rollers 305 of the second conveying wheel device 32; then the flipping driving device 4 is used to drive the workpiece flipping frame 5 to rotate 90° clockwise to reset, and then the front-back moving mechanism 8 drives the flipping driving device 4 and the workpiece flipping frame 5 to move backward, so that the flipping supporting member 55 of the workpiece flipping frame 5 extends between the conveying rollers 305 of the first conveying wheel device 31, so that the workpiece flipping frame 5 continues to flip the glass workpiece on the first conveying wheel device 31.
