Solution Overview
Problem
The existing tape feeder systems face challenges in ensuring the correct combination of support plates and component types, leading to potential human errors during production, which can result in component suction errors or damage due to inappropriate magnetic interactions.
Innovation Solution
A verification system that acquires information on the type of support plate and component supply tape, determines the appropriateness of their combination, and outputs a message to prevent incorrect setups, using sensors and bar code readers to ensure accurate matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support plates with different magnitudes of magnetism are exchanged according to component types, then component stability is improved, but device complexity increases
Solution Approach 1:
The support plate is divided into a magnetic attraction force generation section (magnet) and a non-magnetic support section, allowing independent optimization of magnetic properties and support function. This segmentation enables the magnetic strength to be varied by changing only the magnet section while keeping the support structure standardized.
Solution Approach 2:
The support plate is designed with a standardized interface and structure that can accommodate different magnet strengths while maintaining the same mounting position and basic support function. This universality allows a single support plate design to serve multiple component types by simply exchanging the magnet section or adjusting magnetic properties.
2Reliability
If multiple tape feeders with different support plates are prepared, then component stability is improved, but loss of time increases
Solution Approach 1:
The system transitions from a static configuration where entire feeders must be exchanged to a dynamic configuration where only the support plate can be quickly exchanged. This reduces the time penalty associated with changing component types while maintaining the reliability benefits of matched support plates.
3Manufacturing precision
If visual verification of support plate type is required, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The support plate incorporates color-coded identification markings that correspond to different magnetic attraction force levels. This allows operators to quickly identify the appropriate support plate type without needing to visually inspect technical specifications or understand magnetic properties, making verification intuitive and error-proof.
4Reliability
If support plates with strong magnetism are used for all component types, then component stability is improved, but object-affected harmful factors increase
Solution Approach 1:
The magnetic attraction force is localized to only where needed (in the magnetic attraction force generation section) and is adjusted to the minimum necessary strength for each component type. This ensures strong holding force for magnetic components while applying minimal or no magnetic force to non-magnetic or magnet-sensitive components, preventing harmful effects.

Function Achieved in This Case
Prevents human errors by ensuring the correct combination of support plates and component types, reducing the risk of component suction errors and magnetic damage.
Implementation Method 1
a support plate having a magnet attached thereto is attached to a bottom face section of a tape passage of a tape feeder so as to prevent components in component accommodation recessed sections from being caused to deviate, inclined, or caused to move out from their proper positions by attracting the components to bottom face sides of the component accommodation recessed sections of a component supply tape by virtue of a magnetic attraction force of the magnet
Data Source
AI summary
A support plate, which is configured to support a component supply tape, is provided on a bottom face section of a tape passage, through which the component supply tape passes, of a tape feeder. A computer acquires information on a type of the support plate provided in the tape feeder and also acquires information on a type of components of the component supply tape. Further, the computer determines the appropriateness of a combination of the type of the support plate and the type of the components of the component supply tape so acquired by referring to a database accumulating therein data on appropriate combinations of types of support plates and types of components of component supply tapes and outputs a message corresponding to a determination result of the appropriateness of the combination to at least one of a display device, an audio device, and a mobile terminal.
