Seiko Epson Corporation

The space-saving robots in the G series are designed with Epson's unique Smart Motion Control technology and provide among the industry's best speeds and accuracy, with low residual vibration.

Epson enhanced the specifications and functions important for users to design and develop the system and enabled system optimized for multi-product production and/or supporting environment with water and oily mist.

Features

• Quick, accurate movements shorten work time
• Precise and smooth straight and arch motions improve the quality of sophisticated work
• A high moment of inertia enables a large multi-hand that handles multiple products and items
• A compact manipulator with a wide motion range (a ductless design with inner wiring increases the motion range by 20%)
• The standard lineup is extensive and includes a IP54/IP65-compliant model for wet and oily environments and an electrostatic discharge protected cleanroom model.
• Mounting options enable robots to be installed on a tabletop, wall, or ceilings, for the best layout and most space-efficient system.

* The length of the arm and Joint #3 depend on the specifications. Please refer to the leaflet for details.
* G3 robots are equipped with a curving arm.

Table 1

Cleanroom robots have a shorter joint #3 stroke (G1 = -20 mm, others = - 30 mm)

Several arm configurations are available for G3 series robots

• Staright
• Left-Curved hand
• Right-Curved hand

G1 Series

The robots in the G1 series are the latest and smallest models in Epson's high speed, high-precision "G-series" of SCARA robots, and they provide optimal functionality for the precision assembly and insertion of small parts. Ideally suited for applications in the electronics, semiconductor, printed circuit board, and precision industries, the G1 models have been designed for a variety of uses, including uses as micro-handlers, angle converters, and feeding unit dispensers. The extra-small footprint means they can be easily added to existing cells. They are the perfect choice as a cost-efficient, high-performance feeder for larger robots. A heavier hand attachment is available for the 3-axis model, making it particularly suited for operations such as screw driving and dispensing.

Product features

1. Similar speeds as larger models(Fig. 1)
   
   • Cycle time: 0.29 seconds (175-mm arm) or 0.30 seconds (225-mm arm) with a 0.5 kg payload and a 100-mm horizontal movement and 25-mm vertical movement)
   • Repeatability: ±0.005mm
2. Similar motion range as larger models (Fig. 2)
3. High rigidity and ultra-high precision allow for smaller, simplified mechanism
   
   • The 225-mm arm type has a similar working range as the 250-mm model, resulting in high space efficiency
4. A 3-axis model is also available for heavy hand attachments (max. payload: 1.5 kg)

G3 Series

G3 series robots, simultaneously fast and accurate, excel at small parts transfers and assembly.
The body is ultra compact yet has a large motion range.
The most outstanding feature of the G3 series is its use of a "Curving Arm".
The curving arm expands the motion range to the back of one side and to the inner area of the body.
A left-curved arm and a right-curved arm are available.
The straight arm has the same motion range on both the right and left side.
