Component Confirmation Device Lighting Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Component supply devices face reduced production efficiency due to limited lighting areas and the need to move pallets and lighting devices relative to each other during component pickup, resulting in waiting times and reduced component mounting rates.
Innovation Solution
A component confirmation device with a moving section that synchronizes the movement of a lighting device and pallet relative to each other every pick-and-place cycle, ensuring all components are within the lighting area for imaging and pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pallet is moved to pick up subsequent components every time a component is picked up, then all components can be accessed, but waiting time increases and production efficiency decreases
Solution Approach 1:
The system dynamically switches between two operational modes: (1) moving the pallet for subsequent components, and (2) moving only the lighting device for the target component. This dynamic adaptation allows the system to optimize between complete component access and reduced waiting time, thereby maintaining production efficiency while ensuring all components can be accessed when needed.
2Area of stationary object
If the lighting device has a limited lighting area, then the device size is reduced, but not all components can be illuminated at one time
Solution Approach 1:
The lighting device is made movable and can be dynamically repositioned to illuminate different areas of the pallet. This allows the limited lighting area to cover different components at different times, achieving complete component coverage through sequential illumination without requiring an oversized lighting device.
Solution Approach 2:
The illumination process is segmented into multiple stages, where the lighting device illuminates different portions of the pallet in sequence. By dividing the lighting task into segments corresponding to different pallet positions or component groups, the system achieves complete coverage using a compact lighting device with limited area.
3Ease of operation
If the pallet is moved every pick-and-place cycle, then component access is enabled, but the number of components mounted per unit time is reduced
Solution Approach 1:
The system dynamically determines whether to move the pallet or the lighting device based on the specific pick-and-place cycle requirements. For the target component, only the lighting device is moved, eliminating unnecessary pallet movement and waiting time. This dynamic decision-making process maintains high mounting rates while ensuring proper component access and illumination.

AI summary
A component confirmation device images components arranged in a pallet before the components are picked up to confirm the components based on a captured image of the components. A pick-and-place cycle is defined as a cycle from when a mounting head configured to pick up and mount a component on a board starts picking up a target component that is at least one of the components that the mounting head picks up at one time until when the mounting head mounts the target component on the board. At this time, the component confirmation device includes a moving section configured to move target equipment that is a first one of a lighting device configured to illuminate the target component and the pallet, relative to a second one of the lighting device and the pallet as required every pick-and-place cycle, in imaging of the target component.
