Technical Field

[0001] The present invention belongs to the technical field of tightening devices, and specifically relates to an automatic screw-locking tightening device with an anti-tail-breaking adhesion function. Background Technique

[0002] With the continuous development of industrial automation technology, tightening devices are widely used in automated production lines, mainly achieving the tightening operation through robotic arms, pneumatic devices or simple electric drive systems.

[0003] In the prior art, tightening is directly carried out through mechanical devices. However, due to the lack of tail-breaking treatment, the strength of the raw material may be insufficient, resulting in cracking of the raw material.

[0004] Most of the existing tightening devices lack a flexible material adjustment system. During the material transmission process, problems such as size deviation or non-compliance with specifications are likely to occur. The lack of tail-breaking treatment leads to a decrease in the finished product rate, and the lack of components for detecting adhesion causes the broken tail part of the screw to adhere and flow into the finished product area, thus increasing the generation of unqualified products. Therefore, those skilled in the art have provided an automatic screw-locking tightening device with an anti-tail-breaking adhesion function to solve the problems raised in the above background.
