In modern industrial production, the application of automatic screwdrivers is becoming increasingly widespread, significantly enhancing production efficiency and assembly quality. However, during actual use, the frequent occurrence of skewed screws when using an automatic screwdriver not only affects production efficiency but can also lead to quality issues. Therefore, addressing the issue of skewed screws is of great importance.

Cause Analysis

The occurrence of skewed screws is typically caused by the following factors:

• Insufficient Verticality of Screwdriver Installation: If the screwdriver is not coaxial with the screw hole axis during installation, the screw is likely to deviate from the hole position during tightening, resulting in skewed screws.

• Deviation in Screw Hole Positioning: If the screw hole position is inaccurate or the screwdriver's positioning system is not precise enough, it can prevent the screw from entering the hole vertically.

• Excessive Thread Engagement Speed: During the initial stage of screw insertion, if the rotation speed is too high, it may prevent the screw from smoothly entering the threads, leading to skewed screws.

Solutions

To address the issue of skewed screws, consider the following approaches:

• Ensure Verticality of Screwdriver Installation: When installing the screwdriver, use specialized mounting fixtures and measuring tools to ensure that the screwdriver is coaxial with the screw hole axis. This can effectively reduce the occurrence of skewed screws due to installation deviations.

• Improve Screw Hole Positioning Accuracy: By incorporating industrial camera-based positioning, the accuracy of screw hole positioning can be enhanced. Industrial cameras can monitor the screw hole position in real-time and feedback data to the control system for precise positioning.

• Optimize Tightening Process: During the screw tightening process, a segmented tightening method can be adopted. During the thread engagement stage, reduce the rotation speed to ensure the screw smoothly enters the threads. Once the screw is successfully inserted, increase the speed for rapid rotation. This can effectively prevent skewed screws caused by excessive rotation speed.
