SiTUO Hardware: Focus on Custom Machining
I. Application and Characteristics of Fixtures in Coffee Machines
1. Core Application Scenarios
(1) Machining of Precision Hardware Parts
- Boiler & heating chambers: Made of 304/316 stainless steel and brass. Hydraulic/pneumatic fixtures achieve positioning accuracy ≤0.002 mm, ensuring flatness and concentricity of sealing surfaces for high-pressure (15–20 bar) extraction.
- Brew heads, portafilters & valve bodies: Custom pneumatic jaws + locating pin fixtures are adopted for special-shaped curved and multi-step structures to avoid clamping deformation and guarantee precision of water hole positions and sealing grooves.
- Pump bodies, solenoid valves & fasteners: Multi-station rotary fixtures complete multi-surface machining in one clamping, improving batch consistency for tiny precision components.
- Shell & sheet metal parts: Pneumatic flexible fixtures with food-grade rubber protection are used for grinding and welding of special-shaped shells, preventing surface scratches on automated production lines.
(2) Automated Assembly Lines
- Quick-change positioning fixtures cooperate with manipulators for precise assembly of heating components, waterway modules and electronic parts, with repeated assembly accuracy of ±0.05 mm.
- Special suction/clamping fixtures match delta robots for high-speed sorting and packaging of coffee capsules and cups, realizing fully automated production.
2. Key Characteristics
- High-precision positioning: Positioning accuracy of 0.002–0.01 mm, geometric tolerance ≤0.005 mm, meeting food-grade sealing and high-pressure working requirements.
- High rigidity & anti-deformation: Multi-point support and floating clamping reduce vibration and deformation for thin-walled (≤1 mm) and deep-cavity parts.
- Food-grade compatibility: Contact parts adopt 304/316 stainless steel and food-grade rubber, complying with FDA/CE food contact standards.
- Automation compatibility: Standard interfaces and quick-change structure adapt to CNC machines, robots and automated lines, cutting clamping & debugging time by over 30%.
- Flexible multi-variety production: Modular design enables fast model change for household/commercial coffee machine parts in different materials (stainless steel/brass/aluminum alloy).
II. Application and Characteristics of Manipulators in Coffee Machines
1. Core Application Scenarios
(1) Manufacturing & Production
- Loading, unloading & handling: 4-axis/6-axis manipulators complete picking and transferring of blanks and finished products in die-casting, CNC and stamping processes, boosting efficiency by 2–3 times with 24-hour continuous operation.
- Precision assembly: Collaborative robots (repeated positioning accuracy ±0.02 mm) assemble brew heads, boilers and pump components precisely to ensure consistent sealing and performance.
- Surface treatment: Robots matched with grinding/polishing fixtures process coffee machine shells and portafilters automatically, achieving surface roughness Ra≤0.8 μm with better consistency than manual work.
- Inspection & packaging: Vision-guided manipulators conduct dimensional and air tightness testing, and high-speed sorting & packaging for coffee capsules.
(2) End-use Intelligent Coffee Robots
- Single/double-arm collaborative robots simulate hand-brewing and latte art movements (repeated positioning accuracy ±0.1 mm), realizing 24-hour unmanned operation and cutting operating costs by 60%.
- Equipped with 6-dimensional force sensors, they achieve 0.1N-level force control, adapting to different cup types and accurate control of extraction pressure and water flow.
2. Key Characteristics
- Ultra-high precision: Repeated positioning accuracy of ±0.02–0.1 mm, trajectory error <0.1 mm, ensuring stable coffee quality.
- High flexibility: Quick jaw change and drag teaching support small-batch & multi-variety production, with model change time <10 minutes.
- High efficiency & stability: Production tact 0.5–2 seconds per piece, zero fatigue and error, increasing yield rate by 5–10%.
- Safety & reliability: Collision detection, electronic safety boundaries and emergency stop ensure safety in human-machine collaboration scenarios.
- Intelligent interaction: Optimized extraction parameters via AI algorithms, supporting multi-language and mobile payment for commercial scenarios like malls and offices.
