Developed by Hengjiang Intelligent Technology Co., Ltd. (Hexeon), the SCARA Robot series represents a new standard in automated pick-and-place, sorting, and packaging operations. Built with food-grade materials, proprietary motion control algorithms, and an integrated drive-control-electrical architecture, these robots are engineered to perform reliably across demanding production environments — from bakery lines to pharmaceutical facilities.
SCARA stands for Selective Compliance Assembly Robot Arm. This robot architecture features horizontal multi-joint movement with a vertically rigid Z-axis, which makes it exceptionally fast and precise for planar operations. Unlike 6-axis articulated robots, the SCARA configuration excels at repetitive two-dimensional tasks — sorting, stacking, placing, and transferring items across a flat work surface — while delivering superior speed-to-accuracy ratios. Hexeon's SCARA robots expand on this foundation with an overhead ceiling-mount installation, freeing up valuable floor space and enabling deployment directly above conveyor lines.
Hexeon's food grade SCARA robot series is built around four key technical pillars: an integrated drive-control-electrical system, a patented intelligent vision control platform, high-precision servo motors, and a modular hardware-software framework.
The integrated design consolidates the drive module, motion controller, and power electronics into a single compact unit. This eliminates the need for external control cabinets, reduces cabling complexity, and improves overall system reliability. All control logic runs on Hexeon's proprietary operating system, which supports multi-device input including touchscreen panels, tablets, smartphones, and standard computer interfaces.
The intelligent vision system is a defining feature of the Hexeon SCARA platform. High-resolution cameras combined with AI-based recognition algorithms allow the robot to detect item position, orientation, and shape in real time. This enables dynamic adjustment during pick operations, ensuring consistent placement accuracy even when product orientation varies. The system supports operation under variable lighting conditions and can be recalibrated quickly when switching between product types.
Servo motors with high-resolution encoders provide the mechanical precision behind the robot's ±0.025 mm repeat positioning accuracy. The horizontal multi-joint design distributes load efficiently across the arm, supporting payloads of 15 to 30 kg while maintaining trajectory stability at operating speeds of up to 80 picks per minute.
The Hexeon SCARA robot lineup includes four models — HJ-SC1250-R, HJ-SC1050-R, HJ-SCD0625A, and HJ-SCD7840 — covering a range of arm lengths, payload capacities, and operational radii.
The flagship Scara HJ-SC1250-R features a 600 mm main arm and 450 mm sub-arm, giving it a total travel radius of 1,250 mm. The Z-axis travel is 370 mm. It operates across four axes with the following angular ranges: Axis 1 at ±170°, Axis 2 from -100° to +155°, and Axis 4 at ±200°. Maximum speed per axis reaches 300°/s on Axis 1, 360°/s on Axis 2, 500 mm/s on the Z-axis, and 900°/s on Axis 4. Maximum payload is 30 kg and the body weight is approximately 80 kg. Noise level is below 68 dB(A). The robot mounts either grounded or on a gantry frame and requires a floor load capacity of at least 500 kg/m².
The Scara HJ-SC1050-R offers a more compact reach of 1,050 mm, suited for medium-scale workstations where floor space and cycle time are both critical. The Scara HJ-SCD0625A targets lighter-duty tasks with a 625 mm operational radius, ideal for sorting smaller baked goods or packaged items in confined spaces. The Scara HJ-SCD7840 is designed for medium-arm applications requiring a balance between reach and payload in compact line configurations.
All models share the same ceiling-mount installation profile, integrated electronics design, and food-grade surface treatment standards.
All structural components in contact with the production environment use food-grade 304 stainless steel. Surface finishes are smooth, non-porous, and resistant to cleaning agents used in industrial washdown procedures. The sealed joint design prevents lubricant or particle contamination from reaching food products. This construction approach meets international food safety guidelines and supports compliance with HACCP and GMP requirements.
The ceiling-mount installation further enhances hygiene by keeping the robot body above the product flow. There are no floor-level supports or horizontal frames running through the work area, which reduces contamination points and simplifies sanitation routines. The compact body (40 kg for the HJ-SC1250-R base unit) also reduces the surface area requiring regular cleaning.
Hexeon's SCARA robots support interchangeable end-effectors, allowing rapid adaptation between product types without reconfiguring the robot program. Gripper designs include mechanical clamps for rigid products, vacuum suction cup arrays for flat or smooth surfaces, and combination grippers for irregular items. All gripper materials are food-grade and rated for direct product contact.
The gripper exchange mechanism is designed for tool-free swapping during product changeovers, minimizing downtime on mixed-product lines. The vision system recalibrates automatically after gripper changes to maintain placement accuracy. This flexibility makes the robot suitable for handling frozen donuts, egg tarts, packaged buns, fresh pastries, and similarly varied baked goods without mechanical re-engineering.
Hexeon's SCARA Robot Workstation configuration integrates the standalone SCARA unit with conveyor interfaces, vision hardware, control terminal, and safety enclosure as a complete modular unit. This accelerates deployment and standardizes performance across multiple installations. The workstation variant is particularly suited to clients who require a validated, turnkey automation cell rather than a custom-engineered solution.
For operations requiring broader line coverage, the SCARA Robot Sorting & Packaging Line extends this concept into a full-line configuration. Multiple SCARA units operate in coordinated sequence along a single conveyor, handling sorting, tray-loading, and pre-packaging stages in one continuous flow. Throughput scales linearly with the number of robot units deployed.
Where operational diversity is required — for example, sorting multiple product types simultaneously or combining high-speed and precise placement tasks — Hexeon offers the combined use of SCARA and Delta robots in integrated workstation configurations. The SCARA unit handles heavier or orientation-sensitive placements while the Delta robot addresses high-speed, low-payload tasks. This hybrid approach maximizes line productivity without oversizing any single robot type.
Hexeon also manufactures a Delta Robot series, and the two architectures serve complementary roles. Delta robots excel at extremely high-speed, low-payload pick-and-place (typically under 5 kg), operating at rates exceeding 100 picks per minute. SCARA robots offer greater payload capacity (up to 30 kg), longer arm reach (up to 1,250 mm), and better performance in tasks requiring vertical insertion or lateral transfer across a wide working radius.
In food production contexts, Delta robots are commonly deployed for lightweight item sorting at high volume, while SCARA robots handle heavier trays, stacked products, or downstream packaging tasks. Hexeon's dual-unit and multi-unit Delta robot applications demonstrate how these two technologies scale together within a single line architecture.
Hexeon's proprietary operating system provides the software foundation for all robot motion management. Motion control algorithms handle path planning, velocity profiling, and joint interpolation, ensuring smooth trajectories even during rapid direction changes. Sensor fusion integrates encoder feedback, force sensing, and vision data into a unified position control loop, enabling adaptive grasping that responds to variations in product position or compliance.
The programming interface supports recipe-based task management, where operators define pick patterns, placement coordinates, and gripper parameters through a graphical interface. Switching between product recipes requires only a few input steps, which reduces changeover time significantly on multi-product lines. Remote monitoring via the integrated network interface allows supervisors to review production status, receive fault alerts, and perform software updates without physical access to the control unit.
Within Hexeon's broader production line portfolio, the SCARA robot integrates directly with multiple line types. In bakery contexts, it is used downstream of forming equipment to sort, stack, and load products into trays or packaging containers. This applies across pastry lines, croissant lines, donut lines, and egg tart lines, among others.
Hexeon's production line range includes forming, laminating, and shaping equipment for a wide variety of baked goods. The SCARA robot functions as the downstream automation layer that bridges the gap between shaping and packaging — handling the product after forming but before it reaches the final packaged state. This integration eliminates manual tray-loading and reduces per-unit labor cost significantly on high-volume lines.
While the SCARA robot series is optimized for food environments, the same precision, payload, and flexibility specifications make it suitable for pharmaceutical handling, cosmetics packaging, electronics assembly, and light logistics. In pharmaceutical contexts, the food-grade construction directly satisfies clean-room-adjacent handling requirements. In electronics manufacturing, the ±0.025 mm repeatability supports fine component placement without dedicated precision assembly robots.
