Z-Θ

A linear rotary picker that integrates the Z-axis (linear) and θ-axis (rotary) on a single shaft. The shaft has a built-in vacuum line, so micro components can be picked up, transported and positioned at the required rotation angle. In-house high-performance optical encoders deliver 0.1 μm linear and 0.002° rotary resolution. The patent-pending Polygon Ball Guide suppresses runout, making it ideal for high-speed pick and place of semiconductors, camera lenses and similar parts.

Features

  • Integrated Z-axis + θ-axis linear rotary picker
  • Built-in vacuum line for suction transfer
  • In-house optical encoders (linear 0.1 μm / rotary 0.002°)
  • Patent-pending Polygon Ball Guide

Linear Rotary Picker (Z-axis + θ-axis)

Pick and place units integrating the Z-axis (linear) and θ-axis (rotary) on a single shaft. The ZLR series uses a linear motor for the Z-axis, while the ZVR15-15 uses a voice coil motor. All models use the 3M 10136-3000VE (36-pin) connector.

Linear Picker (Z-axis only)

Linear pickers with a Z-axis (linear) only. The e-Pica series adopts the patent-pending Polygon Ball Guide (PBG): a polygonal post, ball cage and outer tube constrain rotation while delivering high rigidity and smooth high-speed motion with minimal preload.

Internal structure of the Polygon Ball Guide

Polygon Ball Guide (PBG) - balls on four faces suppress runout

Driver & Cable Solution

A host PC, motion controller and servo drivers form a scalable system from 1 to 16 axes. Slot-type drivers plug into an expansion board to add axes, and cable lengths can be specified to order.
