Double-station exposure method

The invention discloses a double-station exposure method, which comprises the steps of: providing a double-station exposure production line; detecting stations; conveying plates; carrying out exposure; and transferring the plates, wherein the double-station exposure production line comprises a first station, a second station, a first suction cup and a second suction cup; the first suction cup sequentially absorbs the plates to transfer to the first station and the second station respectively; after the plates at the first station are exposed, the second suction cup absorbs the exposed plates at the first station to transfer to the next station and the first suction cup supplements to-be-exposed plates to the first station; and after the second station is exposed, the second suction cup absorbs the exposed plates at the second station to transfer to the next station and the first suction cup supplements the to-be-exposed plates to the second station. Compared with a related technology, the double-station exposure method disclosed by the invention is simple to operate and the production efficiency is high.
