The invention discloses an automatic roller shearing, cutting, edging and filleting integrated device comprising an oil pressure lifting platform, a substrate sucking and transferring machine, a side-step conveyor, a right benchmark roller shearing and cutting machine, a first temporary storage conveyor, a side-step corner conveyor, a left benchmark roller shearing and cutting machine, a second temporary storage conveyor, a sub-board conveyor and an edge grinding machine; the oil pressure lifting platform is installed below an feeding end of the substrate sucking and transferring machine, anda manipulator matched with the oil pressure lifting platform is arranged at the corresponding position of the oil pressure lifting platform. According to the automatic roller shearing, cutting, edgingand filleting integrated device, the manipulator is used for putting plates, roller shearing and cutting, the plates are automatically entered the edge grinding machine, and the plates are automatically collected if the edging is not necessary; and therefore, the manpower problem of two-process-based machining on the current market is fundamentally solved, the labor is saved, the labor intensityof workers is reduced, and the corporate profitability is facilitated to be improved.
