One-stop test aging production line

The invention provides a one-stop test aging production line which comprises a manipulator assembly. The mechanical arm assembly comprises a sliding seat, a shifting column, a rack, two linear guide rails, two fixing discs, a portal frame, a supporting frame, a first motor, a lifting frame, a second motor, a jacking air cylinder, a rotating disc, a tray, two supporting rails, four limiting rails, a third motor, a lead screw, two sliding rails and a fixing frame. The two ends of the shifting column are symmetrically and fixedly connected to the adjacent faces of the two fixing discs. When the first motor works, the fixed disc drives the shifting column to be meshed with the rack, the position of the rack is fixed, so that the sliding seat slides along the linear guide rail, the position of the manipulator is adjusted, the traditional belt transmission and transmission chain transmission modes are replaced by the mode, the aging problem is avoided, the stability is good during working, and the service life of t
