A robot integrator located in Jiangsu province provides engineering, manufacturing and integration solutions for 3C manufacturers. They recently equipped a Taiwan electronics factory with composite robots for handling and inspections. With the help of collaborative robots, factories have improved production quality, reduced human error, increased operational efficiency by 20 percent, and saved about 15 percent of their workspace. By incorporating collaborative robots into the production process, workers can perform jobs that require higher skills and generate higher additional values.
The material transfer between process stations for subsequent production line currently still relies on manual labor, and originally the material transfer between the stations is completed manually. The factory hopes to accomplish automatic connection between single stations, but due to limited workspace, it is not suitable to make large scale changes and layout adjustment. So they urgently need to find lightweight and less risky solutions to try.
The factory approached the integrator in the hope that they could provide a solution. After an evaluation at the workplace, the integrator recommended that the factory try a hybrid robot. The AGV takes the workpiece that is taken by a robotic arm and sends it to the testing platform. Then the equipment carries out size and appearance inspections. After the inspections, the robot takes the workpiece and sends it to the next testing station for inspections. The composite robot is composed of an AGV laser navigation vehicle, an ELITE EC66 (6KG load) collaborative robot and a Dashuan gripper. Compared with traditional industrial robots, ELITE collaborative robot has lower power consumption; the average power of a 6kg loaded robot is 250W. The optional 48V DC powered version can draw power directly from AGV. Due to the low power consumption and small structure of the collaborative robot, the loss of AGV’s carrying capacity is relatively small. In the actual operation, there is no need to frequently charge the vehicle, thus shortening the downtime and improving the production efficiency.
“It has been two months since the robot was installed, and we are quite satisfied with the mobile platform.” The factory showed their satisfaction: “The combination of cooperative robot and AGV provides us with the ideal solution. The whole system is very smart, besides being able to complete the planned movement, it also occupies small space. To be honest, this is how I imagined modern materials handling and testing tools would look on a production line.” Small in size but great in applications, I believe the future collaboration robot and AGV combination will bring more surprises to users
The joints of ELITE collaborative robot adopt a light and integrated design, which is different from traditional industrial robots. The systems, including motor, drive control circuit, feedback circuit, speed reduction box, bus, encoder and so on, are all integrated in the integrated joints. The lightweight design ensures that the robot has a high load-selfweight ratio, which can not only reduce the risk and protect the safety of human in the event of collision. Moreover, the weight of the robot is greatly reduced. For example, the weight of the robotic arm with a 3kg load is only 13kg, while the weight of the robotic arm with a 6kg load is 17.5kg. So this type of arm is flexible when integrating with AGVs.
