Product Specifications

Technical details and manufacturing context for Wire Dispensing Unit

Definition
The Wire Dispensing Unit is a critical subsystem within an Automatic Wiring System responsible for controlled wire feeding. It manages wire payout from storage reels, maintains proper tension, prevents tangling, and ensures smooth, continuous wire supply to the wiring head or termination point during automated wiring operations.
Working Principle
The unit typically uses a motorized or servo-controlled mechanism to rotate the wire spool. It incorporates tension control devices (spring-loaded brakes, dancer arms, or electronic tensioners) to maintain consistent wire feed. Sensors monitor wire presence and breakage, while guides ensure proper alignment as wire is dispensed toward the next stage of the wiring process.
Common Materials
Aluminum alloy, Steel, Plastic (guide components)
Technical Parameters
  • Maximum wire diameter capacity (mm) Standard Spec
Components / BOM
  • Spool Holder
    Supports and allows rotation of the wire spool
    Material: Steel
  • Tension Control Mechanism
    Maintains consistent wire tension during dispensing
    Material: Spring steel, aluminum
  • Wire Guide
    Directs wire path and prevents tangling
    Material: Plastic or ceramic
  • Drive Motor
    Provides controlled rotation for wire payout
    Material: Various (motor components)
Engineering Reasoning
0.1-5.0 N wire tension, 0.05-2.0 m/s feed rate, 0.01-0.50 mm wire diameter tolerance
Wire tension exceeds 8.0 N causing permanent deformation, feed rate drops below 0.02 m/s causing wire stalling, wire diameter variation exceeds 0.75 mm causing jamming
Design Rationale: Yield strength of copper wire (210 MPa) exceeded at 8.0 N tension, static friction coefficient (μ=0.15) insufficient below 0.02 m/s feed rate, geometric interference occurs when wire diameter exceeds guide clearance by 0.25 mm
Risk Mitigation (FMEA)
Trigger Spool brake torque exceeds 2.5 N·m due to mechanical binding
Mode: Wire tensile stress exceeds 210 MPa yield strength causing permanent elongation
Strategy: Install torque limiter with 2.0 N·m mechanical slip clutch and Hall-effect torque sensor
Trigger Guide roller bearing contamination with 15 μm particulate matter
Mode: Roller rotational resistance increases by 300% causing wire feed velocity drop to 0.01 m/s
Strategy: Implement IP67 sealed bearings with magnetic particle traps and ultrasonic cleaning ports
