The invention discloses an automatic tilting conveying system. The automatic tilting conveying system comprises at least one tilting conveying module. Each tilting conveying module comprises a conveying rack, a conveying platform rotationally arranged on the conveying rack, and a tilting driving mechanism capable of driving the conveying platform to rotate. The conveying platforms can be tilted inthe conveying process, openings of washing machines are inclined upwards by a certain angle, and thus put-in of vibration blocks and water injection operation are facilitated; and after put-in of thevibration blocks and water injection operation are finished, the conveying platforms can return to the horizontal state so as to normally convey the washing machines, and testing requirements are met.
