On the other hand, for screw rods with small diameters, the frequency of the alternating forward and reverse rotation of the screw rod is reduced, so as to avoid excessive wear of the end of the screw rod and ensure the quality of the screw rod. When the angle of the pneumatic clamp's alternating clockwise and counterclockwise rotation is greater than the system set value, it means that its rotation amplitude is large, making it easier for the screw rod to enter the insertion hole, thereby relatively reducing the clockwise and counterclockwise alternating rotation frequency of the screw rod, which can further reduce the end wear of the screw rod, as well as reduce the wear between the screw rod and the insertion hole, which can improve the screw rod production quality and protect the structure. The screw rod can enter the insertion hole more easily through the vibration generated when the screw rod rotates greatly. At this time, the clockwise and counterclockwise alternating rotation frequency of the screw rod can be relatively further reduced, which can further reduce the screw rod wear and improve the screw rod production quality to the greatest extent. At the same time, the operating energy consumption of the cylinder can be relatively reduced, which plays a role in energy saving and environmental protection, and reduces production costs.

The insertion hole of the insertion block is used to fix the screw rod to facilitate cutting of the screw rod. At the same time, the circular diameter recognition module of the camera is used to identify the circular diameter of the screw rod. The intelligent operation of the cylinder 11 is controlled according to the circular diameter, which can make the screw rod quickly enter the insertion hole faster and more efficiently, thereby improving work efficiency.

For small-diameter screw rods, the forward and reverse alternating rotation angle of the pneumatic clamp 15 is reduced, which ensures that the screw rod enters the insertion hole smoothly and can relatively reduce the energy consumption of the cylinder 11 and reduce costs.

[0019] In step S3, , is the frequency of the alternating forward and reverse rotation of the pneumatic gripper 15, is the maximum forward and reverse alternating rotation frequency of the pneumatic gripper 15; That is, the larger the diameter of the screw rod is, the faster the frequency of the alternating forward and reverse rotation of the pneumatic clamp 15 is; On the one hand, by increasing the frequency of the screw's alternating forward and reverse rotation, the screw is made to vibrate, so that the screw can enter the insertion hole faster, thereby increasing the screw's conveying efficiency. On the other hand, due to the small diameter of the screw, the frequency of the screw's alternating forward and reverse rotation is reduced, thereby avoiding excessive wear on the end of the screw and ensuring the quality of the screw.

[0020] In step S3 and step S4: when hour, The system sets the forward and reverse rotation angle of the pneumatic clamp 15: At this time, the forward and reverse rotation angle of the pneumatic clamp 15 is large, so that the screw rod rotates greatly, that is, , The frequency of alternating forward and reverse rotation of the pneumatic clamp 15 is reduced after the screw rod rotates significantly; when hour: ; When the angle of the pneumatic clamp 15's alternating clockwise and counterclockwise rotation is greater than the system setting value, it means that its rotation amplitude is large, making it easier for the screw rod to enter the insertion hole, thereby relatively reducing the frequency of the screw rod's alternating clockwise and counterclockwise rotation, which can further reduce the end wear of the screw rod, as well as reduce the wear between the screw rod and the insertion hole, which can improve the screw rod production quality and protect the structure.

At this time, the frequency of the screw rod's alternating rotation in the forward and reverse directions is further reduced, which can further reduce the screw rod's wear and improve the screw rod's production quality to the greatest extent. At the same time, the operating energy consumption of the cylinder 11 is relatively reduced, which plays a role in energy saving and environmental protection and reduces production costs.

[0022] In step S3, step S4 and step S5: when hour: , , The pneumatic clamp 15 is rotated alternately clockwise and counterclockwise by the system. The maximum forward and reverse alternating rotation angle of the pneumatic clamping jaw 15 is limited by the system, that is, the forward and reverse alternating rotation angle of the pneumatic clamping jaw 15 is limited, and the limited value is the ratio of the forward and reverse alternating rotation frequency to the forward and reverse alternating rotation angle; The rotation angle of the screw rod is limited, and the limited angle is inversely proportional to the frequency of the screw rod's alternating forward and reverse rotation. That is, the greater the frequency of the screw rod's alternating forward and reverse rotation, the smaller the limited screw rod rotation angle is. This can avoid excessive rotation of the screw rod, and reduce the rotation frequency, preventing the screw rod from deviating from the insertion hole due to excessive rotation intensity and affecting the insertion speed, thereby improving the production efficiency of the screw rod.
