Designed for High Precision Tasks: Several Compact SCARAs, with their 250 or 350 mm working radius and intelligent handling properties, can be used together in the space that would be occupied by a single robot with standard dimensions. With excellent repeatability down to 8 µm (= 8 thousandths of a millimetre) in the horizontal plane, these small models are particularly suited for micro-assembly and high-precision applications.

The smallest members of the Epson SCARA family have working radii between 250 and 350 mm. They are particularly suited to use with smaller products and provide exceptionally fast and precise movement.

The universal option amongst the Epson SCARAs (S = standard) covers, with working radii of 450, 550 and 650 mm, nearly all requirements for assembly in the 5 kg class. Also available as standard in this series are two different Z-axis carriage lengths of 170 mm and 320 mm. Optimum installation is provided by the wide variety of mountings: Whether table-, wall-, bracket or ceiling mounted, there is always space available for one of these machines.

Typical application areas are in the automobile and automobile component industries, manufacture of computer and consumer components, food, pharmaceutical and medical technology industries, semiconductor and telecommunications industries, to mention just a few.

Working space up to 1.70 m and cycle times from 0.38 seconds.

The E2L class (L = large) come into their own, where quick operation over large areas is a necessity. Both the 650 mm version and the 850 mm working radius machine are available as clean room versions up to class 10. Both manipulators are delivered with a Z-axis stroke of 320 mm.
 

The E2H-series is exactly right for you if you have to move heavy loads quickly and precisely. "H" stands for "Heavy" and that refers to the maximum possible payload of 20 kg. The arm lengths used by the robots in this series is 850 mm.

Up to 80 Kg payload; up to 1,500 mm/s

Up to 40 Kg payload; up to 1,500 mm/s

Up to 15 Kg payload; up to 750 mm/s

The RC520 is a real multi-talented device as closed, ready-to-install 19" insert. Up to three robots can be controlled simultaneously with this device. This is always of advantage, if several robots are more or less working closely together at the same location or if your plant is to be later extended at this point. For this purpose, each robot is driven by a separate power element with modern, digital drive engineering.

This system can control up to 3 robots simultaneously. Each robot receives its energy from a separate power element. The illustration shows such a robot under intrinsic control.

Due to its open structure, the PC-based Epson RC420 robot control makes all options available, that a PC has to offer in automation. Just as with the large RC520, the software platform RC+ is used. The versatility and speed are based upon an industrial PC running Windows 2000, equipped with a 850 MHz processor and enable the integration of a wide range of options. In addition, image processing and Ethernet I/O, field bus systems such as Interbus or Profibus can also be integrated and a software interface to Visual Basic/C++ can be created.

The control conforms to the relevant CE guidelines and reduce the torque forces in the "teach-in" phase so that the system is safe and easy to set up. In normal operation, special software continuously monitors all safety-related functions of the robot system. Furthermore, in addition to the emergency stop circuit, there is also the option for installing safety barriers and door contacts in the system.

The RC420 universal control has slots for the usual PC insert cards. Thus, as well as the actual robot control, further control and other tasks can also be handled.

The RC170/RC180 Controller is the starter model in a range of new, compact robot controllers designed to round off the product range for stand-alone controllers.

This new controller is especially compact and even the 6-axis version has only a volume of just under 12 l and weighs 9 kg. This makes it the smallest 6-axis controller available in the market.
Another advantage is the many different ways it can be mounted. Whether wall, ceiling, rack, horizontal or vertical floor mountings, there are the perfect fixing bars available for all configurations.
 

With the Epson VISION GUIDE 3 image processing system, all Epson robots can “learn to see” in the most straight-forward way. For this purpose, VISION GUIDE 3 is integrated into the proven robot software for Windows®. Due to the completely physical and software-related integration directly into the robot control, extremely fast communication (within a few milliseconds) is possible between robot and image processing. For programming purposes, the robots as well as the vision system are programmed on the same Windows engineering interface. Robots and image processing use the same programming language with the same symbols, on a common control. Programming is performed using drag and drop tools and makes the creation of vision applications extremely simple and convenient. It is not necessary to learn a new programming language, as the command range of the SPEL+ standard language is appropriately supplemented by a small number of efficient commands. The associated camera images are also displayed on the same monitor. VISION GUIDE 3 supports up to twelve cameras with all possible camera perspectives: "mobile" on the robot; "above / below" or "outside" the robot’s working area.

The new "Geometric Object" software tool offers a significant time and investment saving. With this, objects can be detected several times faster and more reliably than with the conventional process. The user selects this command from a clearly arranged library and is guided to the target quickly and thus inexpensively. The often complicated, protracted and fault-susceptible linking of several command sequences can be dispensed with. Further processing of the position is then easily performed by the robot in the same programming interface. Position determination is faster and many times more reliable than was possible with, for example, pattern or edge detection. Reductions in the accuracy of position detection are not necessary.

Touching components are found more quickly and reliably by Geometric Object. Even components which are not entirely detected by the camera image, can still be evaluated. Everything has two sides and normally approximately 50% of two-dimensional components lie on the correct side and also partially touch each other along their entire length. Conventional systems usually only find free-lying objects and reject the rest. However, Epson Geometric Object finds these too and identifies all that are only partially within in the camera’s field of vision.

Furthermore, the tool delivers the results of the x-y position as well as the rotary position of the object within milliseconds and with high accuracy. For this purpose, geometrical structures are detected as edge characteristics. It is thus possible to detect one and the same object in varying sizes, i.e. object detection is scalable, without the necessity for repeated learning-in of the component for each change of focal length setting or camera position. The advantage of model-based edge detection is also reflected in the robustness with regard to changes in lighting conditions or slight variations of the object, e.g. due to burrs or dirt. Even touching of components or overlapping is detected. The process is particularly suitable for technically-demanding industrial locations, even under changeable environmental conditions.

Grabbing from the running belt is also designated conveyor tracking and is almost indispensable in many sectors of robot-supported automation.

Sensor tracking is a further, inexpensive technique for conveyor tracking. In this case, the trigger signal is detected by a sensor instead of a camera.

As with robots, conveyor tracking and image processing applications can be found in almost all industrial fields of application:

• Foodstuffs
• Electronics manufacturing
• Automotive suppliers
• Motor vehicle manufacturers
• Foodstuffs and pharmacy
• Household appliances
• Optics
• Solar technology
• Semiconductor technology
• Quality inspection
