[0032] The present embodiment provides an air flotation detection platform for an OLED detection machine, wherein the main channel 3 and the secondary channel 4 on the gas flow channel adopt a straight structure, and the fine channel 5 adopts a curved structure; the main channel 3 and the secondary channel 4 adopt a straight structure to facilitate the flow of the input gas in the gas flow channel, and can more quickly transport the input gas to each fine channel 5; the fine channel 5 adopts a curved structure to quickly reduce the gas flow rate of the gas transported from the secondary channel 4, and the curved structure will construct a curved path, thereby preventing the high-pressure gas ejected from the secondary channel 4 from directly spraying to the air inlet 7 to generate turbulence, affecting the uniformity of the air flow at the outlet of the air flotation platform.

[0033] The present embodiment provides an air flotation detection platform for an OLED detection machine. An exhaust port 10 is provided on the exhaust plate 2. The exhaust port 10 is correspondingly provided to the air inlet 7 opened at the air outlet end of the fine flow channel 5. The gas output by the air inlet 7 will be ejected upward through the exhaust port 10 on the exhaust plate 2. The ejected gas will form a stable air flow layer above the air flotation plate assembly. When the OLED product is tested, the OLED product is placed above the OLED product and will be separated by the air flow layer and will not contact the air flotation plate assembly.
