Automated secondary guidance uploading method and system

Abstract

The invention discloses an automatic secondary guide loading method and system. The method comprises the following steps: 1) transporting a common material box containing a workpiece to a preset position, fixing it, taking pictures with a visual sensor 1, and collecting preset feature points image information, calculate the deviation between the preset feature point and the stored standard position under the visual sensor 1 coordinate system, and transmit this data to the industrial computer; the field of view of the visual sensor 1 can cover the preset position; 2) the industrial computer utilizes the deviation The data corrects the trajectory of the robot, and the position of the corrected robot is used as the initial position of the second guidance; 3) The robot starts the second guidance from the initial position, first descends to the image acquisition position, shoots, calculates the coordinates of the workpiece position and stores it The deviation of the coordinates of the standard position of the workpiece, correct the position of the robot's grasping, grasping the workpiece, and releasing the workpiece. This method utilizes common material box, does not need to turn over box operation, and material box is positioned at the field of view of visual sensor 1 and can finish automatic guidance loading.

Description

technical field [0001] The invention relates to a guiding method for industrial site measurement, in particular to an automatic secondary guiding loading method and system. Background technique [0002] With the development of industrial technology, in the automobile manufacturing industry, automatic guide loading has become an important means to improve production efficiency and liberate productivity. At present, the process of automatically guiding the loading is as follows: firstly, through the box turning, the workpiece placed in the ordinary material box is imported into the high-precision material box, and then the visual sensor is used to determine the position of the workpiece in the high-precision material box and transmit the result to the robot. The robot corrects the trajectory according to the position of the workpiece to complete automatic loading. Existing automatic guide loading mainly relies on high-precision bins and high-precision positioning of warehouse...

AI Technical Summary

Problems solved by technology

Existing automatic guide loading mainly relies on high-precision bins and high-precision positioning of warehouse locations to ensure that the workpiece is within the detection range of the visual sensor and ensure detection accuracy; this is because the maximum tolerance range of the visual detection sensor is only ±70mm , the use of ordinary bins and simple positioning will inevitably fail to meet the detection requirements of visual sensors

However, the processing of high-precision bins and high-precision positioning is difficult, and the processing and maintenance costs are relatively high.
