The invention relates to the field of production equipment for locks, in particular to automatic blade assembly equipment for blade locks. The automatic blade assembly equipment comprises a first feedmechanism, a second feed mechanism, a scanning mechanism and an assembly mechanism. The first feed mechanism comprises a first conveying device, a transfer device and a turning device, the second feed mechanism comprises a second conveying device, a first vibration feed disc and a mechanical arm, the scanning mechanism comprises a second vibration feed disc and a key frame, and the assembly mechanism comprises a first rotary device, a second rotary device, an assembly device and a discharge device. The automatic blade assembly equipment has the advantages that bits of keys are scanned by thescanning mechanism, the first conveying device, the transfer device and the turning device are matched with one another, and accordingly lock cylinders can be fed; the first vibration feed disc, the second conveying device and the mechanical arm are matched with one another, and accordingly blades can be fed; the assembly device, the first rotary device and the second rotary device are matched with one another, and accordingly the blades and the lock cylinders can be assembled; the lock cylinders can be discharged by the discharge device, and the automatic blade assembly equipment is simple instructure and high in practicality.
