machine stand.
（2） Tensioning device
Tensioning device is installed in wire-feeding component to provide proper tension for coil winding.
Tension can be modified by the knobs on the device. Tension will be automatically adjusted after the
modification is completed.
（3） Winding device
Winding device mainly consists of Delta ASDA-B type servo motor (200W), timing belt and winding
flyer and is the winding shaft (Master) of E-CAM operation. Copper wires are winded on the coil die
through the winding flyer. Winding device is the major part of windig operation.
（4） Coil device
Coil device mainly consists of Delta ASDA-B type servo motor (100W), precise ball screw, guide rail
and pneumatic sliding forks and is the coil shaft (Slave) of E-CAM operation. Coil device follows the
winding device and reciprocates to perform the coil spacing action. Coil device is also the major part
of winding operation.
（5） Work stage
Work stage mainly consists of index stepping motor, rotation stage, wire fork and coil die. The work
stage supports multi-task processing, executing die preheating, wire cutting heating, mold releasing
while coil winding is in process.
（6） Cutting device
Cutting device is pneumatic device used in cutting off the wires on the two ends of the completed
coil.
（7） Die releasing device
Die releasing device consists of index stepping motor and pneumatic die releasing device, taking the
completed coil off the coil die.
（8） Hot air system
Hot air system has 2 temperature adjustable 220V heat guns. Users can preheat the coil die before
winding and heat up the completed coil to release the coil from the coil die.
（9） Electric control system
Electric control system has an electric control box and usually a touch panel. In electric control box
we apply DVP-20PM00D as the core of motion control, the touch panel as the human-machine
interface and the servo motor as working device. By this combination, we can perform precise motion
control between winding shaft and the coil shaft, so that the accuracy of coil winding can be obtained.
High speed winding on master shaft and slave shaft can be performed by executing single speed positioning on
winding device(3), together with E-CAM operation on coil device(4). Other operations are similar to general
sequential ladder control and can be executed by general functions of PLC.
