Electronic Component Conveyance Device Sidewall Interval Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component conveyance devices often cause jamming due to the tilting of electronic components during conveyance, particularly when the stack direction of internal electrodes is not aligned with the substrate, leading to mechanical strength and acoustic noise issues.
Innovation Solution
The electronic component conveyance device features a conveyance path with a first magnetic force generation unit in the midstream part, where the interval between sidewalls is larger than in upstream and downstream parts, ensuring the component rotates without tilting, and a second magnetic force generation unit with a weaker magnetic force to facilitate rotation and prevent jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the interval between sidewalls gradually decreases toward the end of the rotation path, then the electronic component is guided into alignment, but the component orientation becomes tilted causing jamming
Solution Approach 1:
The conveyance path is divided into three sections with different sidewall interval characteristics: the upstream section has a larger interval to allow component entry, the rotation section has a maximized interval to prevent tilting during rotation, and the downstream section has a smaller interval to guide final alignment. This local differentiation of geometric properties resolves the contradiction between alignment precision and conveyance reliability.
Solution Approach 2:
The rotation path is segmented into distinct functional sections (upstream, rotation, downstream) with different sidewall interval configurations. Each section performs a specific function: entry, rotation without tilting, and final alignment. This segmentation allows the system to achieve both precise alignment and reliable conveyance by optimizing each section independently.
2Ease of operation
If magnetic force is applied to rotate the electronic component, then the stack direction aligns with the substrate, but the component may tilt and jam in the conveyance path
Solution Approach 1:
The conveyance path is designed with a maximized sidewall interval in the rotation section before the component completes its rotation and enters the narrower downstream section. This provides a cushioning space that prevents the component from tilting and jamming during the magnetic rotation process, allowing smooth alignment without harmful jamming effects.
3Manufacturing precision
If the conveyance path has a narrow interval to guide alignment, then precision improves, but the component cannot rotate freely causing operation difficulty
Solution Approach 1:
The conveyance path is segmented into sections with different interval widths: a wider rotation section that allows free component rotation under magnetic influence, and a narrower downstream section that guides precise final alignment. This segmentation resolves the contradiction by providing both rotation freedom and alignment precision at different stages of the conveyance process.

AI summary
An electronic component conveyance device in which an electronic component is unlikely to jam in a conveyance path. A first magnetic force generation unit is provided lateral to a first sidewall in a midstream part. An interval between the first sidewall and a second sidewall in the midstream part is larger than an interval between the first sidewall and the second sidewall in an upstream part and an interval between the first sidewall and the second sidewall in a downstream part. The first sidewall is flat across the upstream part, the midstream part, and the downstream part.
