System and method for grinding part weld joint based on vision guide robot

Abstract

The invention relates to a system and method for grinding a part weld joint based on a vision guide robot. The system comprises a laser sensor, an image collection module, an upper computer, the robot and a floating grinding head. The laser sensor, the image collection module and the floating grinding head are mounted on the sixth-axis tail end of the robot, the laser sensor is used for collecting the relative position of the robot and a part, the image collection module is used for collecting image information of the part at the specific position, and the upper computer is used for processing the image information so as to determine the weld joint position, and controlling the robot to drive the floating grinding head to grind the weld joint. According to the system, the laser sensor carries out automatic positioning of the collected image, accuracy and uniqueness of the image collecting position each time can be ensured, the system can achieve full-automatic grinding, the work efficiency is high, operation is concise, worker operation is facilitated, the ground product quality is ensured, and efficient and high-quality production of the enterprise is facilitated.

Description

technical field [0001] The invention relates to the technical field of robot grinding, in particular to a system and method for grinding component welds by a robot based on vision guidance. Background technique [0002] With the rapid development of the manufacturing industry, the large-scale shipping ships have made the large-scale port machinery equipment an inevitable trend. Typical large-scale components such as box girders and trusses are the links with the largest workload in port machinery manufacturing. At this stage, my country's port machinery enterprises mainly rely on manual grinding for the welding seam of large components. The degree of automation is low, the grinding efficiency is low, and the grinding operation environment in which the workers are located is harsh, which is not conducive to the health of the workers. In addition, the quality of manual grinding largely depends on the worker's operational skill level. Different workers have different grinding ...

Problems solved by technology

At this stage, my country's port machinery enterprises mainly rely on manual grinding for the grinding of large-scale component welds. The degree of automation is low, the grinding efficiency is low, and the grinding operation environment of the workers is harsh, which is not conducive to the health of the workers.

In addition, the quality of manual grinding depends largely on the worker's operating skill level. Different workers have different grinding levels, so the quality of the polished products cannot be guaranteed, which is not conducive to the efficient and high-quality production of enterprises.
