Method for cutting sealing head for automatic trepanning

Abstract

The invention discloses a method for cutting a sealing head for automatic trepanning. The method includes the following steps: S1, providing a point laser sensor, and mounting the same at the tail end of a robot; S2, providing an upper computer in communication connection with the robot, inputting cutting parameters for trepanning into the upper computer, generating a cutting task, and transmitting the cutting task to the robot; S3, automatically correcting a workpiece coordinate system, relative to the robot, of a to-be-cut workpiece to determine a pose relation between the robot and the workpiece during cutting; S4, acquiring deviation between an actual locating point of a trepanning position on the workpiece and a theoretical locating point; S5, acquiring an original track point of the trepanning position on the workpiece; S6, compensating trepanning track deviation and correcting the original track point to generate an actual track point; S7, performing trepanning cutting on the workpiece according to the actual track point acquired in S6 by the robot.

Description

technical field [0001] The invention relates to the technical field of container manufacturing, in particular to a cutting method for automatic hole opening of a sealing head. Background technique [0002] Head opening is an important link in the container manufacturing process and an important pre-order work for welding operations. At present, it is mainly completed by manual lofting→manual scribing→manual cutting, which has the following shortcomings: When the head specification changes , When the hole diameter, hole position, insertion angle, etc. change, it is necessary to re-stake and mark the line, which is time-consuming and laborious; and the manual setting-out and marking cannot guarantee the accurate trajectory and position of the intersecting line; at the same time, the manual cutting method cannot guarantee the intersecting line The exact trajectory and position of the line. These problems have a very adverse effect on subsequent welding, and affect the appearan...
