Robot Processing Path Correction for Variable Resin Molded Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for processing resin molded articles require teaching and correction due to variations in dimensions, leading to longer processing times.
Innovation Solution
A processing apparatus equipped with an articulated robot, a shape measurement unit, and a workpiece-set-position recognition unit that generates processing-point information based on the recognized set position and processing-target-portion information, allowing the robot to perform specified processing without manual teaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If path information is set by direct teaching or automatic path generation system, then the articulated robot can process resin molded articles, but the processing time increases due to required teaching work and correction of teaching positions
Solution Approach 1:
The system performs self-positioning by automatically detecting the workpiece position and shape using a sensor, then autonomously generating corrected path information without requiring manual teaching operations. The articulated robot serves itself by adapting to workpiece variations through automated feedback.
Solution Approach 2:
The sensor detects the actual position and shape of the workpiece, feeds this information back to the control system, which then generates corrected path information based on the detected deviations from the original path data.
2Manufacturing precision
If path information is set by direct teaching or automatic path generation system, then the articulated robot can process resin molded articles, but manufacturing precision deteriorates due to large variations in workpiece dimensions
Solution Approach 1:
The system dynamically adjusts the processing path based on real-time detection of workpiece position and shape variations. Rather than using fixed predetermined paths, the path information is corrected and updated according to the actual workpiece characteristics detected by the sensor.
Solution Approach 2:
The system changes the path parameters (position coordinates, movement trajectory) based on detected workpiece variations. The control system modifies the original path information by applying correction amounts derived from sensor measurements to accommodate dimensional variations in resin molded articles.

AI summary
A processing apparatus 1 includes: a workpiece-set-position recognition unit 114 that moves an arm distal-end portion to a specified position measurement point to measure a shape of a workpiece in a workpiece set state in which the workpiece is positioned by a workpiece positioning unit, and thereby recognizes a set position of the workpiece; a processing-point-information generation unit 115 that, based on the set position of the workpiece and processing-target-portion information 124 indicating a position of a target portion of the workpiece for specified processing, generates processing-point information 125 indicating a processing point which is a movement point of the arm distal-end portion to perform the specified processing on the workpiece using a processing tool in the workpiece set state; and a workpiece-processing control unit 116 that moves the arm distal-end portion to the processing point based on the processing-point information 125 to perform the specified processing on the workpiece using the processing tool.
