The KOGANEI COMPLIANCE LIGHT catalog introduces a series of precision compliance devices engineered to absorb positional errors during workpiece insertion, pressing, and handling operations. These units feature a lightweight design, making them ideal for integration with robot hands, and offer high rigidity and load capacity. The product line is categorized into two main types: the Parallel Type, which accommodates X, Y, and θ-axis errors, and the Oscillating Type, designed for X, Y, Z, θ, and α-axis error absorption. Various specifications are available to suit diverse applications. The Standard Type provides fundamental error absorption. The High Holding Force Type significantly boosts holding force, offering over double that of standard models, making it suitable for high-speed transfers with holding forces up to 145N (CPLH90F at 0.5MPa) and maximum payloads of 6kg. For cleanroom environments, the Clean System Type meets Class 5 equivalent (FED-STD Class 100) standards, achieved through a dedicated dust collection port and specialized clean grease. The Direct Piping Type allows for space-saving installation by integrating piping directly. Additionally, the Arbitrary Position Lock Type can retain absorbed positional errors during transfer, while the Horizontal Type effectively suppresses gravitational displacement when handling workpieces horizontally with articulated robots. Operationally, these devices function by using air pressure to engage a steel ball, locking the plate when pressurized, and a restraint ring to maintain centering when depressurized, providing a centering force of 3-5N at 0.5mm displacement. Technical specifications highlight a repeatability of ±0.05mm for X-Y movement and ±0.1° for θ rotation, ensuring precise and reliable performance in demanding manufacturing processes such as precision assembly and component placement. The catalog further details internal structures, operational principles, and performance graphs, including data on centering force, holding force, and impact-resistant payload, to guide optimal model selection for specific industrial automation needs.
