When sourcing SCARA robots and gantry robots, the rule of thumb is: prioritize the brand for SCARA robots and system integration capabilities for gantry robots (Source: Industry Landscape). Global SCARA brands: Epson (#1 manufacturer), Yamaha, Denso, Fanuc (Source: Industry rankings); Domestic (Chinese) brands: Inovance, Estun, EVS; Gantry robots: Mostly customized by system integrators—How to find them: Check brand official websites, authorized integrators, and industry platforms (e.g., Yikong and Yisheng are Tier-1 agents; Source: Industry data)—Choose SCARA robots based on the brand and gantry robots based on integration capabilities (solutions are determined by the specific application).
I.
Global SCARA Brands
Epson: World’s #1 SCARA manufacturer / Leader in small-part assembly (Source: Epson); Yamaha: 30+ years of experience / YK-X series (beltless, high-speed design; Source: Yamaha); Denso/Fanuc: High speed and high precision (Source: PW Consulting); Mitsubishi: RH-F series (±0.010mm repeatability); Omron Adept: Integrated following acquisition—Global leaders: Epson, Yamaha, Denso (choose Epson for small-part assembly).
II. Domestic SCARA Robots
Inovance: SCARA selection guide/servo ecosystem (Source: Inovance); ESTUN: Top 10 domestic brand (Source: Industry rankings); EVS: 3–20 kg payload / 400–1000 mm reach / ±0.020–0.050 mm repeatability (Source: EVS); JAKA: Collaborative robots + SCARA; Zowee (ZWX): Common in 3C electronics—Domestic: Cost-effective (sufficient for 3C/light assembly scenarios).
III.
Gantry Robots
Definition: Gantry-style Cartesian coordinate robot (heavy-duty handling/loading & unloading); Suppliers: Customized by system integrators (non-standard products); Integrators: Yikong Automation (Tier 1 agent for YAMAHA/DENSO; Source: Yikong); Core Components: Linear modules + motors + gripper solutions; Advantages: Heavy load capacity/long travel range/low cost—Gantry: Custom-ordered from integrators (designed based on workpiece and cycle time requirements).
IV.
Channels for Finding Suppliers
Brand Official Websites: Epson/Yamaha China divisions (Source: Epson/Yamaha); Authorized Integrators: Yikong/Yisheng (solutions + after-sales service; Source: Yisheng); Platforms: 1688/Alibaba (used/new machines); Trade Shows: CIIF (China International Industry Fair)/Robotics exhibitions; Industry Recommendations: Case studies from peers—Channels: Find authorized partners via official websites, inspect physical products at trade shows (compare quotes from three integrators).
V. Selection Parameters
Payload: SCARA 3–20 kg / Gantry systems up to 100 kg+; Arm Span: 350–1000 mm (Source: EVS); Repeatability: ±0.01–0.05 mm (Source: EVS); Speed: Cycle time (seconds/piece); Degrees of Freedom: 4-axis SCARA vs. 3-axis gantry—Selection criteria: Payload + Precision + Cycle time (calculate process time first).
VI.
Integration Capability Assessment
1. Case Studies (solutions in the same industry); 2. Authorization (brand distributorship/agency qualifications); 3. End-Effector Design (grippers/vision systems); 4. Commissioning (offline programming/trial production);
5. After-sales Service (response time/spare parts)—Assessment: Case studies + Authorization + Integration capabilities (a robot alone is only half a solution).
VII. Procurement Recommendations
1. High-speed assembly of small parts: Choose Epson SCARA; 2. Heavy-payload handling: Choose gantry system integrators; 3. Cost-sensitive applications: Choose domestic SCARA brands (Inovance/Estun); 4. Complete systems: Find authorized integrators (turnkey solutions);
5. Trial production first (fixture prototyping to verify cycle times)—Gantry vs. SCARA: Epson/Yamaha for high-end needs, domestic brands for cost-performance, and integrators for gantry systems (prioritize solution design and verify via trial production).
