KK Single-Axis Robot Technical Whitepaper: Definition, Features, Selection, and Applications

I. Core Definition & Technical Architecture

• Drive System: C3-grade high-precision ball screw (lead 5–50mm optional), transmission efficiency ≥90%
• Guiding System: U-shaped guide rail (straightness ≤0.02mm/m) paired with high-rigidity carriages, delivering ±0.01mm repeatability
• Modular Structure: Standardized aluminum alloy base for rapid assembly and plug-and-play integration

II. Key Components & Coordination Mechanism

1. Precision Transmission Module
   • Ball Screw: Full-circulation raceway design, L10 life ≥10,000 hours (30kg load)
   • Linear Guide: Four-direction equal-load carriage, rigidity 25% higher than traditional guides
2. Power System
   • Compatible with servo/stepper motors, supporting flange-mounted, side-mounted, and folded installation
   • Standard optical limit switches (response time ≤1ms) and home sensors (repeatability deviation ≤5μm)
3. Protection Components
   • Optional dust cover (IP40) or fully enclosed bellows (IP54) for dusty environments

III. Typical Application Scenarios

1. Core Axis for Intelligent Equipment
   • Auto-loading/unloading systems: Collaborates with robotic arms for high-speed material handling (cycle time ≤3s/pick)
   • Laser processing equipment: Provides ±0.02mm positioning for marking/welding heads, enabling 0.1mm linewidth precision
2. Precision Inspection & Measurement
   • Vision alignment systems: Drives camera brackets for micron-level focusing (positioning speed ≤500mm/s)
   • Coordinate measuring machines: Integrates probe for full-stroke linearity error compensation (≤10μm)
3. High-Precision Electronics Manufacturing
   • SMT pick-and-place feed axes: Supports 0201 component picking (vibration amplitude ≤15μm)
   • Lithium battery electrode coating: Ensures ±0.5μm thickness uniformity with coating heads

IV. Core Technical Advantages

V. Systematic Selection Guide

1. Stroke Planning
   • Standard strokes: 100–2000mm (50mm increments), custom up to 5000mm
   • Safety margin: Reserve 10% stroke to avoid limit collisions
2. Condition Matching
   • Dust environments: Choose carriages with dust brushes (foreign object interception ≥95%)
   • High-speed scenarios: Prioritize large-lead screws (≥20mm lead, speed ≤2m/s)
3. Load Verification
   • Dynamic load: Calculate inertia force (F=ma + friction), safety factor ≥1.5
   • Torque matching: Motor torque = (load weight × lead)/(2π×efficiency) + friction torque
4. Control Scheme
   • Open-loop: Suitable for general positioning (≤0.1mm accuracy, with stepper motors)
   • Closed-loop: Servo motor + encoder feedback for precision requirements

VI. Installation & Maintenance Specifications

1. Multi-Dimensional Installation
   • Horizontal: Flatness ≤0.05mm/m, tighten base bolts to 12N·m with torque wrench
   • Vertical: Mandatory motor brake (brake torque ≥1.2×load torque), anti-fall safety device recommended
   • Cantilever: Add auxiliary support for lengths >300mm (rigidity +30%)
2. Full-Lifecycle Maintenance
   • Lubrication interval: Every 100km or 3 months, apply NLGI 2 lithium grease (2–5g/axis)
   • Accuracy calibration: Annual laser interferometer check (allowable error ±5% of initial value)
   • Fault prediction: Monitor carriage noise via vibration sensor (alert at >65dB)

VII. Typical Fault Diagnosis

VIII. Engineering Case: Dual-Axis Rotary Picking Mechanism

• X-axis: KK single-axis robot (500mm stroke, 30kg load) for horizontal material transfer
• Y-axis: Same-spec robot (vertical installation) with vacuum gripper for Z-direction picking
• Rotary module: 90° indexing cylinder, positioning accuracy ±0.1°
  Technical Advantages:
• Picking cycle: ≤4s/cycle (including rotation)
• Position repeatability: ±0.02mm (XY plane)
• Collision protection: Contact force sensor triggering emergency stop (response ≤20ms)
  Benefits: 300% efficiency improvement over manual operation; defect rate reduced from 1.2% to 0.15
