Component Grasping Control Using Failed-Pick Position Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting systems face challenges in properly supplying components on a stage, particularly when holding tools fail to grasp components, leading to inefficiencies and waste.
Innovation Solution
A component mounting system that stores positional information of components that fail to be held by the holding tool, excluding these components from becoming holding targets, ensuring an adequate supply by identifying and avoiding components that are difficult to hold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If components are scattered on a stage and held by a holding tool, then component supply efficiency is improved, but holding failures occur leading to time wastage
Solution Approach 1:
The system performs preliminary imaging and position detection of scattered components before the holding operation. By detecting component positions and identifying difficult-to-hold components in advance, the system can exclude these components from holding targets, preventing holding failures and time wastage while maintaining supply efficiency
Solution Approach 2:
The system uses imaging devices to detect component positions and provides feedback to the control device. Based on this feedback, the control device identifies difficult-to-hold components and adjusts the holding strategy by excluding problematic components, creating a closed-loop system that improves holding success rate and reduces time loss
2Reliability
If holding operations are repeated for failed components, then component supply completeness is improved, but processing time increases
Solution Approach 1:
The system extracts and excludes difficult-to-hold components from the holding target set based on imaging detection and position analysis. By removing problematic components from consideration, the system avoids repeated failed holding operations while ensuring that only holdable components are targeted, maintaining supply completeness without time penalty
Solution Approach 2:
The system changes the parameter of holding target selection by using imaging data to identify and exclude components with positions or orientations that would lead to holding failures. This parameter change in target selection criteria prevents unnecessary retry operations and optimizes the balance between completeness and processing time

AI summary
A component mounting system comprising: a stage configured to scatter components; a holding tool configured to move over the stage and hold components from the stage; a storage device configured to store positional information of components on the stage that the holding tool failed to hold; and a control device configured to control the operation of the holding tool so that components are held while excluding components in the positional information stored in the storage device from becoming holding targets.
