Lezi Xinchuang Automation Equipment (Shanghai) Co., Ltd.

The RR493/scara arm vacuum robot (single arm) realizes the high positioning repeatability and highly reliable vacuum partition performance by adopting DDM (vacuum direct drive motor) for the drive section. The link-arm mechanism driven by steel belt realizes the adoption of long end-effector even with small rotation area.

Small rotation area (small footprint).

Long end-effector available for long reach.

Available for narrow gate opening size (15 mm).

High accuracy.

Available for ultrahigh vacuum.

High throughput.

Available for the AWC option (wafer position compensation).
