Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounting devices face challenges in accurately positioning and mounting electronic components with functional units, particularly light emitting elements, due to issues with suction nozzle alignment and material compatibility, leading to potential damage or adherence problems.
Innovation Solution
A component mounting device equipped with a recognition unit and holding position determination system that uses cameras to identify the functional unit's position and adjust the holding position of the suction nozzle to ensure precise alignment and minimize material stress, incorporating a component supply mechanism and mounting mechanism to accurately place the electronic component on a substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction nozzle holds the electronic component at a fixed position, then the mounting process is simple and fast, but the functional unit may be damaged or the component may adhere to the nozzle due to material incompatibility
Solution Approach 1:
The suction nozzle's holding position is made dynamically adjustable rather than fixed. The holding position determination unit calculates and sets the optimal holding position based on the functional unit's position and material properties, allowing the system to adapt to different component types and prevent damage while maintaining efficient mounting operations.
2Reliability
If the suction nozzle is positioned to avoid the functional unit, then component damage is prevented, but the mounting precision and alignment become more difficult to achieve
Solution Approach 1:
The system uses recognition units to detect the functional unit's position and feeds this information back to the holding position determination unit. This closed-loop feedback mechanism allows the suction nozzle to be precisely positioned to avoid the functional unit while maintaining accurate mounting alignment through continuous position adjustment based on real-time component information.
3Reliability
If the holding position is adjusted based on functional unit position, then component damage is prevented, but the system complexity and control requirements increase
Solution Approach 1:
The holding position determination unit serves multiple functions: it calculates the optimal holding position, determines the mounting position, and coordinates the suction nozzle's movement. This multi-functional control unit integrates recognition, calculation, and actuation control into a single system component, reducing overall system complexity while maintaining component integrity protection.
