Plate conveying device for refrigerator bottom plate machining and working method thereof

The invention discloses a plate conveying device for refrigerator bottom plate machining and a working method thereof. The conveying device comprises a stacking device and a material transferring suction cup installed on the stacking device, wherein a positioning device is arranged on one side of the stacking device, the stacking device is used for temporarily storing batched raw material plates for refrigerator bottom plate machining, and the positioning device adjusts the positions of the raw material plates and then transfers the raw material plates to a positioning feeding device. The conveying device is advantaged in that a material transfer sucker transfers the raw material plates to the position below the positioning device, the position and an angle of the raw material plates are adjusted through the positioning device, the raw material plates are placed on the conveying plate at a required angle, so the positioned raw material plates are directly conveyed to the specific position of a bottom plate ma
