Problems solved by technology

[0002] The traditional hand-held screw locking method has the disadvantages of low efficiency and slow speed. The locking device is aligned with the threaded hole or whether the screw is locked is manually judged, and human factors account for a large proportion.
Using the traditional teaching method of the robot to enter the coordinate information of the threaded hole, the accuracy of the hole position is low, and the shape of the threaded hole is irregular, there are many types, and the operation is relatively cumbersome.

Abstract

The invention discloses a machine vision based robot automatic locking control system and method, and aims at realizing automatic, efficient and accurate locking of a threaded hole to be locked by a robot. The robot is a demonstration robot which is provided with a demonstration box; a locking device is mounted at the tail end of the robot and is used for adsorbing a bolt to be used; the bolt to be used is screwed into the threaded hole to be locked under the control of a controller; a conveying unit for conveying the bolt is capable of conveying the bolt to a fixed adsorption position; a ceramic is used for acquiring an image of the threaded hole to be locked and sending the image of the threaded hole to be locked to the controller; and the controller is capable of comprehensively controlling the robot and the locking device.

Description

technical field [0001] The invention relates to the field of automatic control of industrial robots, in particular to a robot automatic locking control system and method based on machine vision. Background technique [0002] The traditional manual hand-held screw locking method has the disadvantages of low efficiency and slow speed. The locking device is aligned with the threaded hole or whether the screw is locked or not is judged manually, and human factors account for a large proportion. Using the traditional teaching method of the robot to input the coordinate information of the threaded hole has low hole position accuracy, and the threaded hole has irregular shapes and types, and the operation is cumbersome. Contents of the invention [0003] In view of this, the present invention provides a robot automatic locking control system and method based on machine vision, which can realize automatic, efficient and accurate locking of threaded holes to be locked by using robo...
