Turret Winding Mechanism With Magnetic Clutch Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing winding and unwinding devices in battery production systems face challenges in accurately locating the turret at a predetermined position without causing damage to the driver, as they require power cutoff and subsequent sliding, leading to imprecise positioning and potential damage.
Innovation Solution
A winding and unwinding device incorporating a magnetic powder clutch and a controller to control excitation current, allowing the turret to stop at a predetermined position without power cutoff, using a driver connected via a chain, belt, or gear, and a stop member with stop cylinders to ensure precise location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If power supply is cut off to stop the turret, then the turret can be stopped, but the turret slides after losing motor torque and cannot be accurately located
Solution Approach 1:
The magnetic powder clutch acts as an intermediary device between the driver and the turret. It transmits torque from the driver to the turret during rotation, and can be controlled to release torque precisely when the turret reaches the predetermined position, enabling accurate stopping without power cutoff and preventing sliding.
2Speed
If electromagnetic brake is used to lock the turret spindle, then the turret can be stopped, but the driver cannot operate normally when the turret is fixed
Solution Approach 1:
The transmission system is segmented into two independent components: the magnetic powder clutch that controls torque transmission to the turret, and the driver that provides rotational power. This segmentation allows the driver to remain operational and ready while the clutch controls turret stopping, enabling the driver to quickly restart the turret when needed.
3Speed
If the turret slides after power cutoff, then the turret stops, but the positioning accuracy deteriorates
Solution Approach 1:
The magnetic powder clutch is controlled to release torque precisely at the predetermined position before the turret would naturally slide. This preliminary action of controlled torque release ensures the turret stops exactly at the desired location, preventing subsequent sliding and maintaining high positioning accuracy.

AI summary
This application provides a winding and unwinding device and a battery production system. The winding and unwinding device includes a turret, a driver, and a magnetic powder clutch. The turret includes a rotation shaft and at least one winding shaft, the rotation shaft being parallel to the winding shaft. A drive shaft of the magnetic powder clutch is connected to the driver and a driven shaft of the magnetic powder clutch is connected to the rotation shaft of the turret, such that the driver drives the rotation shaft of the turret to rotate. In this application, with the magnetic powder clutch disposed between the turret and the driver, after the turret rotates to a predetermined position, the rotation of the turret can be stopped without the need to cut off the power supply, ensuring the normal operation of the driver when the turret stops rotation, thus avoiding damage to the driver.
