Component Gripper Reference Portion Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting apparatuses struggle to reliably detect the position of leads with varying heights or shapes, leading to inconsistent detection of the distal end of the lead.
Innovation Solution
An information processing apparatus and component gripper system that uses a positioning grip portion with a reference portion to acquire the position of the component relative to the gripped component, allowing for reliable detection of the component's position without relying on the component's image state, utilizing a groove portion for lead accommodation and a distinct color for the reference portion for easy recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the position of the lead is detected by applying horizontal light to the distal end of the lead, then the position can be quickly detected, but the detection becomes unreliable when the height of the lead or the shape of the distal end changes
Solution Approach 1:
The invention introduces a reference portion as an intermediary object that mediates between the imaging device and the component being detected. Instead of directly imaging the lead distal end whose shape and height may vary, the system images the reference portion whose position and shape are controlled to be substantially constant, thereby achieving reliable detection regardless of component variations
Solution Approach 2:
The reference portion serves as a standardized copy or substitute for the variable component features. Rather than attempting to image the actual lead distal end with varying characteristics, the system uses a controlled reference portion that replicates the necessary positioning information in a consistent, detectable form
2Measurement precision
If the position detection relies on the image-capturing state of the component itself, then the component features must be clearly visible, but this becomes problematic when component height or shape varies
Solution Approach 1:
The reference portion acts as an intermediary that provides a stable imaging target independent of the actual component variations. The imaging system captures the reference portion instead of relying on consistent component features, enabling precise measurement that adapts to different component heights and shapes
Solution Approach 2:
The detection system is segmented into two independent parts: the reference portion that provides stable positioning information and the actual component that may vary. This segmentation allows the measurement system to focus on the stable reference portion while remaining adaptable to component variations

AI summary
A control device 50 is configured as an information processing apparatus which is used for a mounting apparatus 11 for mounting a component 60 on a board S. The control device 50 acquires an image, including at least a reference portion in a state where a component 60 is gripped by a component gripper having a positioning grip portion that grips the component 60 in a positioned state, and having the reference portion that represents a reference position serving as a predetermined relative position to the position of the component 60 gripped by the positioning grip portion, acquires a position of the reference portion based on the acquired image, and acquires a position of the component 60 based on the relative position to the acquired position of the reference portion.
