Robot visual guiding system

Abstract

The invention relates to a robot visual guiding system used in the car sheet pressing process. The robot visual guiding system comprises a sheet conveying belt, a six-axis robot, an industrial camera and a robot control system. The robot visual guiding system is characterized in that sheets are conveyed by the sheet conveying belt to the position under the industrial camera; the industrial camera shoots and transmits part positions; and the robot control system receives position information, compares the position information with preset position coordinates, and controls the six-axis robot to complete part position adjusting operation. According to the robot visual guiding system, automatic adjustment of the sheet positions can be achieved, the part correction speed is increased, the sheet position accuracy is improved, and the machining quality of the sheets is improved.

Description

technical field [0001] The invention belongs to the technical field of field bus and industrial Ethernet, in particular to a robot vision guidance system. Background technique [0002] In the stamping process of automobile sheet metal, in order to ensure the consistency and interchangeability of the size and precision of the parts, various positioning methods must be used to ensure the correct position of the sheet metal in the stamping process, so as to produce qualified products. Therefore, ensuring the position accuracy of the sheet is of great significance to the production of the product. Traditional stamping equipment uses encoders and stoppers as a guide system. When the sheet material is transported to a specific position, the corresponding stopper rises, and the parts stop positioning through impact. The speed of this device is slow, which will affect the production speed of the whole line, and the plate will be slightly shifted and deformed during the impact proce...

The speed of this device is slow, which will affect the production speed of the whole line, and the plate will be slightly shifted and deformed during the impact process, which will affect the normal operation of the equipment

[0003] Disclosed in CN105964453A is a spraying system and method based on visual positioning. The system generates a visual signal of the position of the part through the acquisition device, and calculates the position deviation value of the workpiece according to the ideal position information of the pre-stored working feature point, and according to the position deviation value to adjust the positional relationship between the spraying equipment and the workpiece; however, this positioning method is slow in efficiency and complicated in process, and cannot improve production efficiency
