Robot assembly system workpiece assembly method

Traditional robot assembly systems have been widely used in many large-scale manufacturing industries. These robot assembly systems are designed based on a high-precision operating environment. When assembling large components, multiple robots need to work together. Only in this way can many different parts be handled efficiently. The ability of these systems to adapt to bias is generally limited by the time it takes to search for edges and feature locations.

Typically, these features are limited to a single robot and can only be partially corrected. If a complex fixture is used, it can alleviate the problem to a certain extent, but it increases the cost accordingly, and reduces the flexibility of assembling a unit workpiece into a large specific part.

The system is currently mainly used in the manufacture of aircraft fuselages, but this technology is also fully applicable to all structures that are easily deformed during assembly. The research team has built a fully functional demonstration unit system with excellent performance that meets assembly tolerance requirements. This technology is entirely possible to revolutionize the quality of manufacturing processes such as automotive bodies.

Each robot is equipped with a small software module installed in the controller , which is the connection interface between the robot and the network and the Interbus bus. This software is used for program call and signal exchange between the robot and other robots and unit coordination devices before the execution of the program, so as to realize the advanced handling and assembly work of the robot end effector. The end-effector with excellent performance in this unit has been developed for the handling and fastening of materials, and the handling of the end of the load is highly reconfigurable, ensuring that it can handle the handling of a large number of different parts without frequent Replace the end effector. In order to achieve the fuselage assembly, the project team also developed a pair of end-effectors for drilling, drilling countersunk holes and installing solid rivets. This type of actuator is mounted on two high-load industrial robots in opposite directions, and the components are riveted between the two robots.

The latest scientific research results will greatly improve these uncertainties for large-sized parts that may be distorted during processing. It is hoped that this will bring about the quality of manufacturing and processing such as automobile bodies.
