AI Technical Summary

Technical Problem

In existing technologies, the adjustment efficiency and accuracy of the partition spacing of the insert frame are low. The manual adjustment method is not suitable for automated production lines, and the high-cost servo system is difficult to popularize.

Method used

The movement of the partition is driven by a linear module, with cylinder-assisted limit and automatic locking of the electric screwdriver bit. The combination of guide optical axis and linear bearing ensures smooth sliding, and displacement sensor detects the position. The combination of cylinder and linear module reduces the dependence on high-cost servo system.

Benefits of technology

It achieves fully automated adjustment of partition spacing, improving work efficiency and accuracy, reducing costs, and is suitable for small and medium-sized production lines, ensuring PCB board clamping stability and quick changeover.
