Intelligent finger joint lumber preparation production line

The intelligent finger joint lumber preparation production line comprises a contour detecting and sorting unit, cache feeding units, a machining unit and a visual detecting unit, the discharging end of the contour detecting and sorting unit is connected with the multiple cache feeding units, each cache feeding unit is connected with the machining unit, and the machining unit is connected with the visual detecting unit. The discharging end of each machining unit is connected with a visual detection unit, and the visual detection units are connected with stacking and sorting equipment. The sizes of the timbers are detected and classified at the front ends of the machining line bodies, the timbers of different specifications are fed into the different line bodies to be machined, continuous feeding is achieved through the cache feeding unit in front of machining equipment, and the flatness of the machined face is automatically detected after machining is finished. According to the invention, human resources are s
