Visual guide loading system suitable for vehicle top cover automatic carrying process

Abstract

The invention discloses a visual guide loading system suitable for a vehicle top cover automatic carrying process. The system comprises a robot, a gripper heightening disc, a robot gripper, a visual three-dimensional scanner, a scanner connecting mechanism, an industrial control cabinet, a robot control cabinet, a valve island, a vacuum generator, a clamping cylinder and a vacuum sucker. Comparedwith the prior art, through scanning of angle areas of large-size metal plates by the visual scanner, the identifying precision and the positioning precision are improved, the carrying guide precisionof the large-size metal plates can be improved to +-0.5 mm, and the design cost of a tool for repositioning in middle is saved; and as the selected visual scanner acquires six-degree-of-freedom coordinate information of workpieces, is wider in detecting range, and allows the position placing deviation of the workpieces in a range of +-70 mm, the positioning requirements of the workpieces are greatly reduced, and the loading guide carrying of the visual system can be met without needing finish positioning of material frames.

Description

technical field [0001] The invention relates to the technical field of automatic handling of automobile body-in-white parts, in particular to a vision-guided feeding system suitable for the automatic handling process of an automobile roof. Background technique [0002] In the current automobile manufacturing industry, robots have been widely used to complete various handling, assembly, testing, spraying and other tasks. With the advancement of Industry 4.0, the use of robots is more intelligent and information-based. The application of 2D vision and 3D vision enables the robot to complete the handling and assembly of various complex working conditions. Based on the vision-guided feeding system, the robot can be realized without the need for high-precision positioning of parts, not only the efficiency It also eliminates various abnormal problems in the handling process, such as not being able to grasp the workpiece, damaging the workpiece, and not grasping tightly, etc. It is...

AI Technical Summary

Problems solved by technology

[0003] In the current auto parts handling station, high-precision material boxes and fine positioning tooling are commonly used to ensure that the positioning accuracy of parts in the material box remains consistent, and then the robot completes the grasping and handling operations according to the grasping program. Both the production of the hand and the production of the material box require high precision to ensure the success of each grasp, high cost, poor stability, many faults, and low work efficiency
