The buffer 820 can prevent the collision caused by too fast flow of the supporting plate. The buffer 820 may be a blocking cylinder, and when the blocking cylinder rises, the blocking cylinder contacts with the supporting plate, after the blocking cylinder is aligned, the sensor 830 generates a sensing signal, the conveying belt 810 stops rotating, so that the supporting plate stays on the backflow mechanism 8, and the conveying is performed when the downstream backflow mechanism 8 is idle.

Therefore, the automatic detection equipment for one-time burning can efficiently carry out Gamma burning detection on the display panel, reduce the middle circulation process of the display panel and shorten the detection period.
