[0027] The working principle of this utility model is as follows: When the first station 2 is lowered to its lowest position, the external forklift places the stacked material frame 5 containing the blank material into the first station 2. The motor drives the material frame 5 to rise to the material picking position of the external robot arm. The external robot arm puts the blank into the machine tool and then puts the processed product into the empty material frame 5 in the second station 3. After the blank is picked up, the conveying unit picks up the material frame 5 and stacks it into the second station 3. Then, the drive motor drives the first station 2 to rise by the height of one material frame, so that the next material frame 5 full of blank material below rises to the picking area. At this time, the second station 3 lowers by the height of one material frame, thereby ensuring the height of picking up and putting down the material.
