[0003] At present, including the patents previously applied for by the applicant, the working process of the glass hot bending machine is basically that the mold carrying the glass comes out of the automatic loading and unloading equipment located on one side of the hot bending machine, enters the hot bending machine, and after processing, is output from the other end of the hot bending machine. The mold rotates and returns to the automatic loading and unloading equipment from one side of the hot bending machine. Since the automatic loading and unloading equipment is equipped with loading and unloading mechanisms, its volume is relatively large. In this way, the hot bending machine and the automatic loading and unloading equipment form an L-shaped arrangement.

[0037] The automatic loading and unloading equipment of this scheme is different from the automatic loading and unloading equipment applied for previously in the following aspects:

[0038] The first automatic loading and unloading device 4 further includes a first feeding assembly 47 and a first discharging assembly 48; the first feeding assembly 47 and the first discharging assembly 48 are arranged on both sides below the XZ axis transport module.
