Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component conveyance devices struggle to reliably align the stack direction of internal electrodes in multilayer ceramic capacitors, especially at high speeds, leading to inconsistent mechanical strength and acoustic noise issues.
Innovation Solution
The electronic component conveyance device features a conveyance path with varying sidewall intervals and strategically placed magnetic force generation units to facilitate rotation and alignment of internal electrodes, including a first magnetic force generation unit positioned higher than half the interval between sidewalls to separate the component from the bottom surface, ensuring reliable alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic component is conveyed at high speed, then productivity is improved, but the alignment reliability of internal electrode stack direction deteriorates
Solution Approach 1:
The conveyance path is divided into three distinct sections: upstream part with narrow interval, midstream part with wide interval for rotation, and downstream part with narrow interval for alignment. This segmentation allows the component to undergo controlled rotation in the midstream while maintaining stability in upstream and downstream sections, enabling reliable alignment even at high conveyance speeds
Solution Approach 2:
The sidewall intervals are dynamically varied along the conveyance path rather than maintaining a constant width. The interval expands in the midstream part to enable rotation and contracts in upstream and downstream parts for stable conveyance and alignment. This dynamic geometric configuration allows the system to adapt to different operational phases (conveyance, rotation, alignment) within a single continuous path
2Force
If the magnetic force generation unit is positioned close to the bottom surface, then the magnetic force effect is enhanced, but the component rotation capability is reduced
Solution Approach 1:
The magnetic force generation unit is positioned not only in the lateral direction but also at a specific height above the bottom surface (between 0.05 to 0.2 times the interval P). This three-dimensional positioning creates a magnetic field that acts on the component from above, generating both lateral magnetic force for rotation and vertical magnetic pressure for separation, thereby achieving both rotation capability and magnetic force effectiveness simultaneously
3Stability of the object's composition
If the sidewall interval is narrow, then the component is constrained and stable, but rotation is hindered
Solution Approach 1:
The conveyance path is divided into three distinct sections: upstream part with narrow interval, midstream part with wide interval for rotation, and downstream part with narrow interval for alignment. This segmentation allows the component to undergo controlled rotation in the midstream while maintaining stability in upstream and downstream sections, enabling reliable alignment even at high conveyance speeds
Solution Approach 2:
The sidewall intervals are dynamically varied along the conveyance path rather than maintaining a constant width. The interval expands in the midstream part to enable rotation and contracts in upstream and downstream parts for stable conveyance and alignment. This dynamic geometric configuration allows the system to adapt to different operational phases (conveyance, rotation, alignment) within a single continuous path
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration ensures highly reliable alignment of internal electrode stack directions, reducing jamming and acoustic noise by allowing controlled rotation and separation of components during conveyance, thereby enhancing mechanical strength and noise reduction.
Implementation Method 1
a first magnet to apply magnetic force to an electronic component so that internal electrodes of the electronic component are aligned in a predetermined direction
Implementation Method 2
An interval P2 between the first sidewall and the second sidewall in the midstream part is larger than an interval P3 between the first sidewall and the second sidewall in the downstream part. This facilitates rotation of an electronic component in the midstream part
Implementation Method 3
A height of a center of the first magnetic force generation unit with respect to the bottom surface is higher than P3/2
