Application research of internal spray door opening robot

Painting is an important part of the four major processes of automobile manufacturing. With the development of China's automobile industry in recent years, the inner surface of robots has been widely used in automobile painting lines. As the world's leading robot manufacturer, FANUC has mature robot products and rich solutions for internal surface coating technology.

The P-20iB is a FANUC-developed door-opening robot specifically designed for interior surface coating.

The robot body has a 3-axis configuration, which can be installed in both ground and rail to cope with the different requirements of the coating line stop-go and converyor tracking.

In order to meet the needs of different customers, the P-20iB robot can be equipped with different types of door opening devices.

The pin type door opener is a traditional door opening device. The workpiece is grasped by contacting the window of the door panel, and the mechanical displacement trigger sensor of the pin during the pressing process determines whether the grab is successful.

The magnetic hammer type door opener is a new generation of door opening device developed by FANUC. The workpiece is grasped by the magnetic hammer sucking the inside of the door panel. When the magnetic hammer sucks the workpiece, the position of the magnetic hammer is sensed by the optical fiber, so as to judge Whether to crawl successfully. Compressed air is used to release the magnet from the workpiece surface when the workpiece is released.

Compared with the pin type door opener, the magnetic hammer type door opener does not actively contact the workpiece during the process of grasping the workpiece, and the workpiece is not affected by the force, so the paint film of the surface is not damaged or the position of the workpiece is deviated. Contact damage to the workpiece.

At the same time, as car design solutions are changing with each passing day, more and more car manufacturers will apply the design of the door opening to new models.

The unique 2, 3-axis bi-directional bending design of the P-20iB robot also provides a perfect solution for the flexible collinearity of the internal spray station. It not only reduces the investment cost of customers, but also provides a broad production platform for the development of new models for customers.

In terms of software, the P-20iB robot also installed FANUC's special painting robot software PaintTool, which greatly simplifies the process of process programming. It not only reduces the time for installation and debugging, but also reduces the difficulty of customer maintenance and secondary development.

In the process of running the robot, as long as the StartPartCheck subroutine is inserted in the command, the robot can start to identify the workpiece and monitor it in real time.

Similarly, inserting the StopPartCheck robot into the command releases the workpiece and closes the workpiece monitoring function.

Through the P-20iB robot application, FANUC's internal spray system can flexibly respond to various challenges and help the rapid development of the Chinese automotive industry.
