[0002] A screw machine is a small machine that automatically locks screws. Its action structure can generally be divided into two parts: a feeding part and an electric screwdriver part. The feeding part is responsible for screening and providing screws, while the electric screwdriver part is responsible for taking out and locking the screws. The emergence of screw machines has not only improved work efficiency but also reduced the intensity of manual work.

[0003] Chinese patent application number CN 208409107 U discloses an air suction automatic screw locking machine, comprising a screw machine base and a screw machine gun main body fixing plate, a programming control box is arranged on the front middle outer surface of the screw machine base, a switch is arranged on the front side outer surface of the screw machine base, a fixing plate is arranged on the upper middle outer surface of the screw machine base, a screw feeder is arranged on the front end of the fixing plate, and a screw standard detection box is arranged on the rear end of the fixing plate;

[0004] The above-mentioned screw locking machine absorbs the screw through the gun head, and then moves it under the control of the linear module. After the screw is moved to the position of the threaded hole of the workpiece, the screw is driven into the threaded hole to complete the screw locking work; when the above-mentioned screw locking machine drives the screw into the threaded hole of the workpiece, although it can accurately locate the position of the threaded hole of the workpiece, when driving the screw, the above-mentioned screw locking machine cannot control the force of driving the screw, which easily causes the screw to be driven deeper into the workpiece, causing damage to the workpiece, and also making the connection of the screw unstable, thereby affecting the quality of the workpiece;

[0005] To this end, we provide a double-station screw locking device. A protective cover is attached to the top of the placement box where the workpiece is placed, and the protective cover is provided with auxiliary holes corresponding to the positions of the threaded holes of the workpiece. The automatic screw locking machine drives the screws into the threaded holes of the workpiece through the auxiliary holes of the protective cover. With the buffering of the auxiliary holes, the automatic screw locking machine can be effectively prevented from damaging the workpiece due to excessive force in driving the screws.
