Robot-based automatic assembly system and automatic assembly method

Abstract

A robot automatic assembling system, comprising: a robot having a manipulator for holding a component to be assembled; a positioning system configured to roughly position the component; a vision system configured to accurately identifying position and direction of the component held by the manipulator; and an assembling station where the robot performs the assembling operation of the component. The robot automatic assembling system is configured adaptively select different assembling paths for the component according to assembling accuracy required by the component to be assembled. The different assembling paths at least comprise a first assembling path from the positioning system directly to the assembling station and a second assembling path from the positioning system through the vision system to the assembling station. The automatic assembling system may assemble different components by following different customized assembling paths.

Description

technical field [0001] The invention relates to an automatic assembly system and an automatic assembly method, in particular to a robot-based automatic assembly system and an automatic assembly method for assembling sheet metal components. Background technique [0002] Sheet metal components are often very thin, deform easily, and have surfaces that are easily scratched or marred, making the assembly of sheet metal components a very challenging operation. [0003] At present, the assembly operation of the sheet metal elements is usually performed manually, so the assembly efficiency is low, and in order to ensure the productivity of the assembly work, it takes a great effort to train the operators, increasing the production cost. Moreover, the assembly accuracy is mainly guaranteed by manual experience, and the strict consistency of assembly accuracy cannot be guaranteed. [0004] As future products are entering an era of multiple configurations and rapid replacement, the t...

Problems solved by technology

[0002] Foil elements are usually very thin, deform easily, and their surfaces are easily scratched or marred, so the assembly of foil elements is a very challenging operation

[0003] At present, the assembly operation of sheet metal elements is usually performed manually, so the assembly efficiency is low, and in order to ensure the productivity of the assembly work, it takes a lot of effort to train the operators, which increases the production cost

Moreover, the assembly accuracy is mainly guaranteed by manual experience, and the strict consistency of assembly accuracy cannot be guaranteed.

[0004] As future products are entering an era of multiple configurations and fast replacement, the traditional manual assembly mode can no longer meet the requirements. It is necessary to develop a new assembly system and assembly method that is flexible, versatile, fast adaptable, and highly automated.
