Component Mounting Pickup Logic for Drop Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting machines face increased costs and reduced production efficiency due to the need for additional detection systems to prevent component dropages, and existing solutions require stopping the mounting operation when a drop is detected.
Innovation Solution
A component mounting machine that uses a combination of a component detecting section, a holding detecting section, and a remaining detecting section to determine if a component has dropped without directly detecting the dropped component, utilizing existing machine configurations to curtail cost increases and allow continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple pairs of light emitters and light receivers are added to detect dropped components, then component drop detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The invention makes existing detection devices perform multiple functions: they detect both component presence at the supply position and component holding status by the mounting tool. This eliminates the need for separate dedicated detection systems, thereby reducing device complexity while maintaining reliable component drop detection capability.
Solution Approach 2:
The existing detection devices are utilized to serve the dual purpose of component presence detection and holding status detection. The system makes the existing infrastructure self-sufficient by programming the control device to interpret detection results in multiple contexts, eliminating the need for additional specialized sensors.
2Reliability
If mounting operation is stopped when a dropped component is detected, then component damage is prevented, but production efficiency decreases
Solution Approach 1:
The control device continuously receives feedback from detection devices about component presence and holding status, and dynamically adjusts the mounting operation accordingly. When a dropped component is detected, the system provides feedback to stop the mounting operation only for the affected area, allowing continuous production overall.
Solution Approach 2:
The mounting operation is made dynamic rather than static - the control device adjusts operation status in real-time based on detection results. The system can stop mounting only when necessary (when dropped components are detected) and resume normal operation when components are successfully mounted, thereby maintaining high production efficiency while preventing damage.
3Measurement precision
If additional detection sections are added to determine component dropage, then detection accuracy is improved, but cost increases
Solution Approach 1:
The invention makes existing detection devices perform multiple functions: they detect both component presence at the supply position and component holding status by the mounting tool. This eliminates the need for separate dedicated detection systems, thereby reducing device complexity while maintaining reliable component drop detection capability.
Solution Approach 2:
The invention merges the functions of component presence detection and holding status detection into a single integrated system using existing detection devices. The control device combines multiple detection results (component presence, holding status, and remaining component detection) to accurately determine component dropage, achieving high measurement precision without adding physical detection hardware.

AI summary
A component mounting machine including a component supply device to supply a component to a supply position; a component transfer device to use a component mounting tool to pick up the component from the supply position and mount the component on a board; a component detecting section to detect whether the component is present at the supply position before or while the component is being picked up by the component mounting tool; a holding detecting section to detect whether the component mounting tool is holding the component following pickup; and a remaining detecting section to detect whether the component remains at the supply position in a case in which it is detected by the holding detecting section that the component is not being held by the component mounting tool; and a dropped determining section to determine whether the component has dropped.
