High-speed SCARA mechatronics, sub-milligram carat balances, and real-time sorting loops engineered for continuous diamond factory lines.
The robot automatically detects diamond coordinates on the tray via high-speed optical feeds. Utilizing custom vacuum end-effectors, the SCARA arm instantly picks up the stone, stabilizing it and initiating the weight measurement sequence without human delay.
Features a high-resolution load-cell balance module that isolates external vibrations. Weight sensors communicate via dedicated serial ADCs at high frequency to record the exact carat mass up to three decimal places with absolute consistency.
An integrated logic analyzer instantly evaluates the recorded weight against configurable sorting brackets. In less than 50 milliseconds, the software assigns the destination bin and plans the mechanical movement route.
After measurement, the robot places the diamond into the appropriate collection box according to its exact carat category. Advanced path-planning kinematics ensure smooth, accurate movement, eliminating physical impact or chipping risks.
The complete process—from picking the diamond to placing it into the correct box—is completed in less than 6 seconds. This rapid sorting cycle enables high-throughput production lines to achieve up to 600 sorting operations per hour.
Advanced motion control and precision calibration ensure consistent positioning and repeatable sorting. The system maintains calibration tolerances of ±0.01mm over long production runs with minimal measurement drift.

SCARA Mindron RH-3CRH - Port 10003
Engineered for harsh industrial floor environments. High-reliability components, low thermal footprints, and autonomous watchdog recovery systems enable continuous operation across multiple daily shifts.
Operators can define custom carat ranges and assign each range to a specific output box based on production requirements. Presets are saved locally as JSON configurations and can be switched dynamically from the console.
Equipped with comprehensive hardware protection layers. Built-in physical safety enclosures, software collision detection, emergency stop triggers, and axis load limits keep operators and the equipment safe.
Industrial-grade mechanical assemblies require minimal physical upkeep. Self-lubricating joints, enclosed electrical channels, and modular quick-release vacuum nozzles minimize operational downtime and reduce maintenance costs.
Fully modular integration capabilities. The system supports expansions with additional sorting arms, automated tray feed conveyors, multi-spectral inspection vision systems, and direct ERP enterprise databases.
