AI Technical Summary
In existing quilting machines, manual adjustment of the needle and shuttle is inefficient and inaccurate, while the lag of B-axis commands in the automatic adjustment mode leads to large needle and shuttle synchronization errors, which may cause machine vibration and safety hazards.
A dual-axis servo drive is used, combined with a three-closed-loop algorithm, to calculate the position loop, speed loop and torque command of the A-axis and B-axis respectively. The actual position and speed are obtained through the encoder, the deviation is calculated and calibrated, and the synchronous control of the needle shuttle is realized.
It improves the synchronization accuracy of the needle shuttle, simplifies the system structure, reduces costs, and avoids machine vibration and safety hazards.
