The invention provides a sawing method for unedged sawn timber based on a photoelectric curtain wall. The narrowest position of the side edge of the sawn timber from an overlooking direction is determined by using a calculating device and a sawn timber scanning device, and the sawing position of a saw blade is adjusted through the calculating device, wherein the sawn timber scanning device includes a conveyor belt and an photoelectric curtain wall device, the photoelectric curtain wall device includes a sensor fixing frame and light curtain sensors fixed to the sensor fixing frame, The light curtain sensors are linearly arranged and the arrangement direction is perpendicular to the conveying direction of the conveyor belt, and each light curtain sensor includes an infrared emitting end andan infrared receiving end respectively arranged on and below the transmission surface of the conveyor belt; the emitting ends emit infrared rays to form a sawn timber scanning light curtain when thesawn timber is scanned; an
