Abstract

The invention discloses a high-precision assembly system and an assembling method. The assembling system comprises a feeding module, an assembling module, an assembling operation module, a measurementand control module and an assembling information module, wherein the assembling operation module comprises a robot and a six-degree-of-freedom displacement table, the six-degree-of-freedom displacement table is arranged on a product assembling table, the six-degree-of-freedom displacement table is used for assembling products, the robot is used for grabbing the products to be assembled on the feeding module and moving the products to be assembled to the position right above the six-degree-of-freedom displacement table, the measurement and control module comprises a measurement module, two groups of same measurement devices of the measurement module are oppositely arranged, each measuring device comprises a linear laser sensor and a visual camera, and the linear laser sensor and the visualcamera are in communication connection with the six-degree-of-freedom displacement table. According to the system and the method, the products can be carried through the planar robot, and precise posture adjustment of the products in the assembling process is achieved through the six-degree-of-freedom displacement table; and the robot and the six-degree-of-freedom displacement table are matched with each other to realize a product assembling process with high-precision assembling requirements.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a high-precision assembly system and an assembly method. Background technique [0002] For large-sized products that have matching spigots, high-precision assembly requirements, and good rigidity, technologies such as multi-degree-of-freedom robot motion mechanisms, force-machine vision-laser displacement sensing, multi-information coupling, and pose adjustment can be used to overcome product Flexible docking, flexible grasping and flexible assembly. However, for large-sized products with special materials, weak rigidity and no matching seam, the products cannot collide during the assembly process, so it is not suitable to use flexible butt joints, and it is difficult to achieve high-precision small-gap assembly. There is a loss of precision between the fixture of the robot and the end of the robot, there is a loss of precision between the fixture and the parts to be...
