Machine Overview: Immobilizer Coil Automatic Winding
The 12 spindle immobilizer coil winding machine is a fully servo-controlled system designed for fine copper wire winding on immobilizer and ignition coil bobbins.
Core Capabilities:
- Simultaneous winding on 12 spindles
- Ultra-fine wire handling with closed-loop tension control
- Programmable winding turns, layers, and pitch
- Automatic wire cutting and clamping
- Recipe-based program storage
Detailed Working Principle
Step 1: Bobbin Loading
Bobbins are manually or automatically loaded onto the 12 spindles depending on the production line configuration.
Step 2: Wire Feeding & Tension Control
Each spindle is equipped with independent tensioners to maintain uniform copper wire tension throughout the winding cycle.
Step 3: Precision Winding
Servo motors ensure accurate turns, pitch, and layering as per the programmed recipe. All 12 coils are wound simultaneously.
Step 4: Wire Termination
After completion of winding, the machine performs automatic wire clamping and cutting to ensure consistent lead length.
Step 5: Unloading
Finished coils are removed manually or transferred automatically to the next process such as soldering, taping, or testing.
Machine Construction & Mechanical Design
Heavy-Duty Machine Frame
The machine is built on a vibration-free, rigid industrial frame to ensure stability during high-speed winding. Structural rigidity is critical to maintain winding accuracy over long production shifts.
Individual Spindle Drive System
Each of the 12 spindles is driven through precision servo motors or synchronized drive mechanisms. This ensures:
- Identical RPM across spindles
- Controlled acceleration and deceleration
- No wire stretching or slack formation
Advanced Wire Handling System
Immobilizer and ignition coils typically use fine enamel copper wire, where even micro-level tension variation can affect inductance values.
Closed-Loop Wire Tension Control
The machine uses advanced tensioners to maintain consistent wire tension throughout the winding process. This results in:
- Perfect layer formation
- No enamel damage
- Stable electrical characteristics
Automatic Wire Break Detection
Sensors continuously monitor wire continuity. In case of wire breakage, the machine stops automatically, preventing defective coils.
