Moving Frame: Load Capacity 0.5-5 kg, Travel Range 0.5-10 mm

Component Specifications

Definition

The moving frame is a critical structural component within autofocus actuators, designed to provide stable, low-friction linear motion along a defined axis. It typically interfaces with voice coil motors or piezoelectric actuators to achieve micron-level positioning accuracy for optical elements like lenses or mirrors in imaging systems.

Working Principle

Operates on electromagnetic or piezoelectric actuation principles where controlled force moves the frame along guide rails or flexures, maintaining alignment while minimizing parasitic motion. Position feedback from sensors (encoders, capacitive sensors) enables closed-loop control for precise focus adjustment.

Materials

Aluminum alloy (e.g., 6061-T6) for lightweight rigidity, stainless steel (304/316) for corrosion resistance, or engineered polymers (PEEK, UHMW-PE) for low friction. Surface treatments include anodizing, nickel plating, or PTFE coatings.

Frequently Asked Questions

What is the primary function of a moving frame in autofocus actuators?

It provides controlled linear motion to position optical elements (like lenses) with high accuracy for focus adjustment in imaging systems.

How does material selection impact moving frame performance?

Materials affect weight, stiffness, thermal stability, and friction. Aluminum offers light rigidity, stainless steel provides durability, and polymers reduce friction without lubrication.
