Component Supply Device Stick Case Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component supply devices, such as stick feeders, lack effective traceability management for electronic components, making it difficult to accurately distinguish between different stick case units and manage the lot or type of supplied components during the component mounting process.
Innovation Solution
A component supply device with a loader capable of accommodating multiple stick cases in a stacked state, a component transporting path, a detector to count electronic components, and a determiner to change stick cases based on measured component numbers, ensuring accurate management and traceability of electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a stick feeder is used to supply electronic components, then the component supply capacity is improved, but the traceability and management of component lots and types deteriorates
Solution Approach 1:
The system implements feedback mechanisms through component detectors that continuously monitor the transporting path and count components. The determiner processes this feedback information to detect stick case changes, ensuring traceability is maintained through continuous information feedback about component supply status and lot identification
Solution Approach 2:
The patent replaces manual tracking and mechanical identification methods with automated detection systems. Optical or sensing detectors automatically identify and count components, substituting mechanical counting and manual lot tracking with automated electronic detection and information processing systems
2Productivity
If multiple stick cases are stacked to increase supply capacity, then the component supply capacity is improved, but the difficulty of detecting and measuring component changes deteriorates
Solution Approach 1:
The component transporting path serves as an intermediary zone where components from stacked stick cases are sequentially extracted and monitored. The detector positioned on this path acts as a mediator that indirectly detects stick case changes by counting components as they leave each stick case, converting the complex problem of monitoring multiple stacked cases into a simple sequential counting process
Solution Approach 2:
The system segments the component supply process by treating each stick case as an independent unit with a known component count. The determiner divides the total component flow into discrete segments corresponding to individual stick cases, allowing detection of changes by monitoring transitions between these segmented units through sequential counting

AI summary
A component supply device of the disclosure includes: a loader being capable of accommodating a plurality of stick cases in a stacked state; a component transporting path transporting one or more electronic components supplied from the plurality of stick cases to a predetermined component supply position; a component detector being disposed on the component transporting path, the component detector detecting one or more electronic components on the component transporting path; a component number measurer measuring a first number of electronic components based on the detection result of the component detector; and a determiner determining a change of stick case which supplies one or more electronic components to the component supply position based on the first number of electronic components measured by the component number measurer and a second number of electronic components unloaded from the component supply position.
