Epson robot: a reliable guarantee for easy automation

when it comes to Epson, people's first reaction is often printers and projectors. In recent years, the rapid development of Epson robot in the field of industrial robots is widely attracting attention from the manufacturing industry. In order to be closer to the Chinese market, Epson robotics officially established a service center and marketing headquarters in China in October, 2009, which is fully responsible for the marketing, sales, technical support and after-sales service of Epson robotics products in the material biological structure and biological function industries in Chinese Mainland. At present, the products promoted in China are mainly 4-axis industrial robots and 6-axis industrial robots. With rich experience and diversified technologies accumulated over the years, Epson robot provides users with efficient and easy-to-use solutions and defines a new connotation of easy automation

Epson launched the first SCARA robot for precision assembly in 1983. Since 2010, Epson has ranked first in the global SCARA market for three consecutive years. At present, SCARA h is the most representative horizontal multi joint robot of Epson. This product provides high-precision and high-speed dual-mode. Using Epson's unique intelligent control technology, in the high-precision mode (the comprehensive positioning accuracy is +/-0.02mm), it can effectively suppress the vibration in the stopped state. When handling 2 kg heavy objects, the standard cycle time of the product (horizontal 300mm, vertical 3 25mm, door shaped reciprocating motion, speed and acceleration at the stop position are 0) can reach 0.29 s. Behind the excellent action characteristics is the efficient combination of Epson robot through servo control, precise deceleration, coding positioning and software programming. In addition, Epson fully entered the 6-axis robot market in 2009, and established the industrial solution operation Department in 2013. Relying on the global sales and service network, through close cooperation with system integrators, Epson helps manufacturing users improve productivity and achieve stable operation

diversified technologies build core advantages

as early as the 1980s, Epson industrial robots have been applied to the assembly line of Seiko watches in Japan. With the characteristics of high speed, high precision, low vibration and miniaturization, Epson industrial robots have greatly improved labor productivity on the premise of ensuring reliability. After years of development, Epson has successively developed its own diversified technologies such as unique servo control technology, pressure sensing technology, software platform technology and visual tracking and identification. At the same time, Epson has actively explored the self-discipline control of robot arms and built a complete product system with robot products as the core, covering servo controllers, software development platforms, intelligent visual processors for processing with supplied materials and end clamping devices

one of the core technologies of industrial robots is to realize the high-speed movement and precise positioning of robots under load. At present, the control of robot is mostly through the combination of encoder, servo control and high-precision reducer to complete the operation action, which will have the problems of delay and effectiveness. Epson small robot is equipped with a control chip at the head, which can understand the motion posture of the robot at any time, realize accurate positioning under intelligent control, reduce the requirements for the reducer, and provide users with a more economical solution. Another advantage of this control mode is that it provides high-speed mode and high-precision mode for users to choose. According to the application requirements of the robot, appropriate positioning mode can be adopted

controller is the brain of robot. Unlike other robot suppliers, Epson has two-layer controller products. Equipped with a high-performance PC open architecture controller and a powerful compact low-end controller. It can handle real-time control operations independently of Microsoft Windows applications. Epson provides low-cost, high-performance compact controllers with complete functions and many integration options for customers with small budgets to help users shorten the project development cycle and save money

with the help of the software platform, the person who wants to consider the largest force bearing device of the tested material has the thinking. At present, most integrated equipment manufacturers develop a set of software to complete the communication between robots and peripheral devices. In order to enable industrial users to focus on and facilitate the realization of robot automation, Epson has provided a perfect and unified RC (robot control) software application platform, which can control the surrounding PLC and tooling fixtures, so that integrators only need to consider the needs of customers when completing system integration without worrying about the matching and compatibility of relevant equipment. Because of the user interface which is easy to understand and vivid, users can achieve the ideal productivity with the lowest programming cost

the vision system is the robot's eyes. With the identification and tracking of Epson CV1 vision controller, the robot can realize the sorting action at high speed and accurately. At present, in view of the high production capacity requirements of 3C industry, the high beat action of the robot is required to ensure the smooth operation of the transmission belt. Epson's belt tracking technology can ensure higher picking accuracy (0.1mm) without stopping production line. The picture is generated by the camera, and the subsequent operations are completed by the robot and related auxiliary devices. The color recognition can be completed with the color camera. The Epson projector is used as the light source to project hundreds of times in the horizontal and vertical directions in a short time, and then the software analysis is used to complete the picture analysis in the three-dimensional space, so as to complete the 3D imaging through one camera. In addition, each Epson CV1 visual controller can be connected to 4 cameras, and each robot can be connected to 2 CV1 visual controllers, providing sufficient expansion space for user visual control

Figure 1: equipped with the optional robot camera and Epson projector, the robot can have the function of three-dimensional object recognition, and the price is cheaper than before. The picture on the left shows that the robot accurately detects and picks up screws of a specific length from a tray with randomly placed screws of different lengths. With the three-dimensional object recognition function, parts do not need to be arranged orderly, which can improve productivity and reduce costs at the same time

Figure 2: the end effector can safely and continuously pick up soft and fragile objects. In the experimental environment, the robot even successfully picked up objects such as tofu

the end effector is the two hands of the robot, which can not only accurately pick up, but also effectively control the clamping pressure to ensure that the workpiece is not damaged. In the past, the pressure sensors of large robots were mostly unidirectional, which were used for precision control during grinding operation. The pressure sensor independently developed by Epson can provide six degrees of freedom, small size and outstanding cost performance. Epson has broadened the application level through this technology. For example, in the application of electronic manufacturing industry, when the plug-in acts, it can sense the pressure to ensure efficiency and effect. When accurately clamping various tiny devices, it can reduce the drop rate caused by insufficient stability, improve work efficiency, and meet the requirements of high-speed operation in the electronic industry. The gripper with pressure sensor can reliably complete the insertion and removal operation under the condition of 10 um clearance to achieve precision assembly, for example, in the assembly process of stator and rotor of small motors in 3C industry. In addition, the robot can also complete the bottle cap screwing operation under specific damping requirements to meet the operation during the trial production of vaccines with certain risks in the pharmaceutical industry. According to the application requirements of pressure sensing, Epson is ready to help users establish functional options and integrate them into the RC software platform

Figure 3: the end effector is installed at the lower part of the mechanical arm, which can accurately grasp, clamp and insert objects of different shapes and sizes, including cylinders, and can automatically adjust the applied grip force while operating, so as to prevent the robot from crushing or damaging the bottle body when opening and closing the caps of medicine bottles and cosmetics bottles

dual arm autonomous robot shows the future trend

as the next generation robot, dual arm autonomous robot is an important direction of Epson's product research and development. The two arm autonomous robot has vision, touch and thinking, and can autonomously select the best travel route. The built-in pressure sensor can coordinate the movement of the two arms, transport and assemble the workpiece without damage. The robot can independently identify the position and direction of the object, adjust the force of the object to avoid injury, evaluate the safety conditions, make decisions and perform tasks, and complete complex operations

the most outstanding feature of Epson autonomous dual arm robot is its humanoid functions such as vision, sensing, decision-making and task execution. Epson's two arm robot is equipped with four cameras. Like the human eye, it can accurately identify the position and direction of objects in three-dimensional space. Through the newly developed visual sensor, the robot can grasp objects of different shapes and sizes, and can directly use tools used by human beings without special tools. In addition, the robot is small in size and light in weight. It can easily change the application position and flexibly respond to emergency production adjustments. Epson dual arm autonomous robot is expected to be commercially available by the end of march2016. At present, many specific plug-in operations in the electronics industry have not reached the expected yield and stability. In the production process of automobile parts, although the output of many high value-added connectors is small, the manufacturing requirements are high. Autonomous robots will have certain use space in the above fields
