Industrial Applications

1. High-Speed Electronic Component Pick-and-Place

Utilized in Surface Mount Technology (SMT) and PCB assembly lines to rapidly pick, transfer, and accurately position small, lightweight microchips and delicate electronic components using custom 3D-printed or machined micro-fingers.

Problem Solved

Solves the challenge of maintaining high-speed automated throughput without overloading fast-moving delta robots, while delivering the sub-millimeter placement accuracy required for modern microelectronics assembly.

2. Automated Micro-Vial Handling in Laboratory Diagnostics

Deployed in automated liquid handling systems or diagnostic sorting machines to grip and transfer small-diameter micro-vials, pipettes, or test tubes between testing and incubation stations.

Problem Solved

Eliminates the risk of crushing fragile glass or plastic labware during automated transfers by providing a highly controlled, low-force grip with minimal jaw backlash, ensuring sample integrity and cleanroom compatibility.

3. Micro-Mechanical Watch Gear and Shaft Assembly

Integrated into precision micro-assembly robotic cells to handle, align, and insert tiny mechanical gears, springs, and shafts for watchmaking, optical devices, or micro-motor manufacturing.

Problem Solved

Overcomes the difficulty of reliably grasping sub-centimeter metallic parts with extremely tight engineering tolerances, preventing angular deviation or jamming during the precision insertion processes.
