The screw machine includes an automatic screw alignment unit, an automatic screw conveying unit, an automatic screw tightening unit, and a detection unit during the locking process.

The screw automatic alignment unit mainly arranges loose screws neatly and outputs them individually. The whole unit can be achieved through a vibrating disc sorting mechanism or a rocker arm screw sorting mechanism.

The screw automatic conveying unit mainly transports the entire row of screws individually to the working head of the screw tightening unit.

The screw automatic tightening unit includes a rotating power part and a screw introduction part. The common ways to import screws are blowing and suction. Generally speaking, the blowing type is more efficient than the adsorption type due to its continuous operation without the need for back and forth movement of the head. However, the blowing type itself is limited by the shape and aspect ratio of the screw, and not every type of screw is suitable for the blowing type. The detection unit includes the detection of screw leakage, floating lock, jamming and other issues.

The commonly used automatic screw locking machine should also include functions such as workpiece alignment and screw hole alignment.

There are commonly single axis screw tightening systems and multi axis screw tightening systems.

The single axis screw tightening system, when combined with an X-Y robotic arm or transfer platform, can achieve fully automatic screw tightening. The XY table automatic screw locking machine is particularly suitable for screw locking with multiple holes on a single workpiece, and has high work efficiency.
