[0002] In the processing and production of some furniture, the connection between the components of the furniture will adopt the mortise and tenon structure. The manual mortise and tenon processing has low precision and low efficiency. The use of mortise and tenon machines to assist can effectively improve the efficiency of wood processing in furniture.

[0003] The existing patent announcement number CN112776109B discloses an automatic wood tenoning machine, which includes: a frame and a tenoning device; the tenoning device is arranged on the frame; and also includes: a conveyor belt, a first pulley, a first pulley and a second motor for driving the conveyor belt to rotate; the frame is provided with a first motor; the first pulley and the second pulley are both rotatably arranged on the frame. The wood body is placed on the conveyor belt, the second motor is started, the conveyor belt starts to rotate, and the wood body on the conveyor belt is transmitted to the flat belt. When the first photoelectric sensor recognizes that the end of the wood body is against the support plate, the first photoelectric sensor starts the second motor, the first pulley rotates, and the flat belt starts to rotate. When the second photoelectric sensor recognizes that the wood body on the flat belt is located directly below the tenoning device, the second photoelectric sensor turns off the second motor, the first pulley stops rotating, and the flat belt stops rotating. When the first photoelectric sensor recognizes that the end of the next wood body is against the support plate again, the first photoelectric sensor starts the second motor, the first pulley rotates, and the flat belt is transmitted to the tenoning device. At the same time, the tenoning device tenons the wood body.
