Design and Features

Vacuum-oriented mechanical design

The SRBZ970C is presented as a vacuum manipulator that uses magnetic-fluid sealing as its sealing method, a technique widely used in vacuum motion systems to reduce leakage while enabling smooth rotary motion.

Key design elements highlighted in published descriptions include:

• Magnetic-fluid sealing for vacuum suitability and stability

• Steel-belt transmission (often selected in clean/vacuum mechanisms to reduce particulate generation compared with some geared drivetrains)

• Low noise and low vibration operating characteristics, with a stated focus on stable running and precision

Motion structure and degrees of freedom

The SRBZ970C is specified as having 2 degrees of freedom (2-DOF)—a configuration frequently used for planar wafer or tray transfer where a compact kinematic chain can deliver repeatable radial and rotational placement.

Control, safety, and usability features

Published product descriptions highlight several operational and safety functions:

• Networked control system

• Anti-collision protection and collision-sensitive protection features intended to reduce damage risk

• Dynamic deviation correction and updated trajectory planning to improve motion rhythm (cycle time) and productivity

• A large-screen teach pendant described as improving ease of commissioning and debugging

• Customization options (e.g., arm size) to fit specific application constraints

Applications and Use Cases

The SRBZ970C’s combination of vacuum sealing, low-vibration operation, collision protection, and high repeatability positions it for precision handling workflows in clean or vacuum-compatible production environments.

Semiconductor and vacuum-process handling

Vacuum manipulators are frequently deployed for:

• Wafer transfer between process modules, load ports, and inspection stations

• Tool-side handling inside vacuum-adjacent or controlled mini-environments

• Contamination-sensitive pick-and-place where stable motion and sealed mechanisms reduce process risk

The SRBZ970C’s published vacuum tolerance and helium leak-rate specifications align with this category of applications.

Display, electronics, and high-cleanliness automation

Clean transfer robots are also used in advanced electronics production where:

• Particles can affect yield (e.g., precision components, optical elements)

• Cycle time and repeatability influence overall line throughput
  SIASUN broadly markets industrial robot systems across multiple industries, reflecting this wider deployment context.

High-throughput, safety-focused automation cells

Listings emphasize trajectory planning improvements and dynamic deviation correction, which are typically valuable in:

• Repetitive transfer cycles where small timing improvements scale into meaningful throughput gains

• Lines where misalignment or minor deviations can cause scrap, downtime, or tool alarms
