The time for loading and unloading the substrate on the single-mesa device is T1, the time for alignment is T2, the exposure time is T3, and the time required for producing 2 substrates is 2 x (T1 + T2+ T3). The table top of the equipment bears the substrate, the process can be sequentially executed, and when one of the three processes of loading and unloading, alignment and exposure is executed, the components of the other two processes of the equipment are in a standby state. According to the automatic feeding and discharging single-table-board double-station equipment, two substrates are exposed at the same time, the exposure efficiency is doubled, and meanwhile, the feeding and carrying assemblies arranged in the two spaces up and down and the discharging and carrying assemblies arranged in the two spaces up and down can independently feed and discharge the two substrates, so that the carrying efficiency of the substrates is doubled, and thus the feeding, discharging, aligning and exposing of the two substrates can be carried out at the same time, the time required for producing 2 substrates is T1+ T2+ T3, half of the time is saved compared with that of common single-table-board equipment, and the equipment efficiency is improved by 100%.
