When the second lifting platform 31 is aligned with the main discharge port 12, the first lifting platform 21 Aligned with the main material inlet 11, the third lifting platform 41 is located below the main material outlet 12, and now the fourth lifting platform 51 is aligned with the first lifting platform 21, so that the first rotating shaft 22 and the fourth rotating shaft 52 form a plane. The uniform conveying platform transports the glass substrate 100 conveyed by the upper equipment into the first layer of the second cassette 53 through the main feeding port 11, the first rotating shaft 22, the secondary feeding port 131 and the fourth rotating shaft 52 in sequence, Then the second cassette lead screw 542 drives the second cassette 53 to rise until the second cassette 53 is filled, and then the fourth lifting platform 51 descends. When the fourth lifting platform 51 is aligned with the secondary discharge port 132 , the first lifting platform 21 , the second lifting platform 31 and the third lifting platform 41 are driven by the first platform lead screw 6 to return to the initial position. At this time, the fourth lifting platform 51 is aligned with the third lifting platform 41, and at this time, the glass substrate 100 in the second cassette 53 passes through the fourth rotating shaft 52, the secondary discharge port 132, the third rotating shaft 42 and the main discharge port 12 in sequence. Finally, it is transported to the lower equipment. When the second cassette 53 is transporting the glass substrate 100 to the lower equipment, the upper equipment is transporting the glass substrate 100 to the first cassette 33 because the second lifting platform 31 has returned to its position. This cycle is repeated, thereby reducing the number of empty trips, and ensuring the normal inflow of the glass substrate 100 through the mutual cooperation of the first, third and fourth lifting platforms 51 when the second lifting platform 31 is not in its original position, and improving the equipment. To meet the needs of the beat, thereby improving the transmission efficiency.
