Tool Station Angle Recognition for Component Holding Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting machines, the inability to accurately determine the accommodation angle of holding members deviates from the predetermined angle can lead to improper removal and mounting of components, increasing the likelihood of errors.
Innovation Solution
The implementation of a tool station with multiple identification sections and a determination section that can recognize different accommodation angles by exposing specific identification codes or shapes, allowing the system to adjust its recognition state to determine the angle difference between the actual and predetermined angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shielding member covers identification sections in a close state, then the holding member is securely protected, but the determination section cannot recognize the identification sections for angle detection
Solution Approach 1:
The identification section is divided into multiple separate identification marks (first identification mark and second identification mark) positioned at different angular locations. This segmentation allows the determination section to detect angles even when part of the identification section is covered by the shielding member, as at least one mark remains visible for detection.
2Productivity
If the determination section attempts to recognize identification sections in the close state, then the process is efficient, but recognition fails when the first identification section is covered
Solution Approach 1:
The determination section dynamically switches between detecting the first identification mark and the second identification mark based on which mark is actually visible. This dynamic adaptation ensures reliable angle detection regardless of the shielding member's position, maintaining both efficiency and reliability.
3Measurement precision
If multiple identification sections are provided at different angular positions, then angle difference determination becomes possible, but the device complexity increases
Solution Approach 1:
The multiple identification marks serve multiple functions: they enable angle detection, provide redundancy when partially covered, and allow determination of angle differences. This multi-functionality justifies the addition of multiple simple marks without proportionally increasing overall system complexity.

AI summary
A component mounting machine includes a tool station and a determination section. The tool station detachably accommodates a holding member including a main body section which can hold a component to be mounted on a board and multiple identification sections which can identify multiple accommodation angles. The determination section determines an angle difference in which the accommodation angle of the holding member differs from a predetermined accommodation angle. At least one identification section of the multiple identification sections is defined as a first identification section, the at least one identification section being exposed when the accommodation angle of the holding member is the predetermined accommodation angle in a close state in which the multiple identification sections are partially covered by a shielding member. When the determination section cannot recognize the first identification section in the close state, the determination section attempts to recognize a second identification section.
