Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bending devices for leaded components on boards lack convenience in mounting leads at various positions, as they are limited to bending in a specific N-bent state without flexibility in positioning.
Innovation Solution
A bending device with a movable bending unit that includes a pair of bending bodies with insertion holes and a holding section, allowing the leads to be bent in a different direction by sliding, and a moving device that enables the bending unit to be positioned perpendicular to the leads' insertion direction, facilitating mounting at any board location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bending unit is fixed in position, then the structure is simple and stable, but the leads can only be bent at a specific position on the board, reducing versatility
Solution Approach 1:
The bending unit is transformed from a fixed structure to a movable one by introducing a moving device that enables it to translate in the X-direction (perpendicular to lead insertion direction). This allows the bending unit to be dynamically repositioned to accommodate leads at various locations on the board, directly resolving the contradiction between positioning flexibility and structural simplicity.
Solution Approach 2:
The bending unit is designed with universal functionality to operate at multiple positions on the board. By combining the movable bending unit with the sliding mechanism, the same bending unit can service different lead positions without requiring multiple dedicated bending units, thereby improving versatility while controlling device complexity.
2Adaptability or versatility
If the bending unit is made movable in the X-direction, then leads can be mounted at any position on the board, but the device complexity increases
Solution Approach 1:
The bending unit incorporates a moving device that enables translation in the X-direction, transforming it from a static to a dynamic component. This allows the bending unit to reach various positions on the board for lead bending operations, directly addressing the positioning capability requirement while accepting the necessary increase in device complexity.
3Adaptability or versatility
If the slide section is designed to slide perpendicular to the insertion holes, then the leads can be bent in different directions for N-shape configuration, but the device structure becomes more complex
Solution Approach 1:
The slide section is designed to slide in the X-direction (perpendicular to the insertion holes' arrangement direction), enabling the bending bodies to move relative to each other. This dynamic sliding action allows the leads to be bent in different directions to form N-shape configurations, providing bending direction flexibility while managing the structural complexity through a straightforward sliding mechanism.
Solution Approach 2:
The bending unit is segmented into two independent bending bodies, each with its own insertion hole. The slide section enables these segmented bending bodies to move relative to each other, allowing independent positioning and bending direction control for each lead, thereby achieving bending flexibility through segmentation.

AI summary
A cut and clinch unit is provided with pair of slide bodies, and each slide body is configured from movable section and fixed section that slidably holds the movable section. An insertion hole is formed in the movable section. A pair of leads of a leaded component are inserted into the insertion holes of a pair of slide bodies, and the pair of leads are bent into an N shape by each movable section being slid. The cut and clinch unit is movable in the XY directions by operation of a moving device. Also, the distance between the pair of slide bodies can be changed freely. Accordingly, it is possible to mount leads at any position on a board in a state bent into an N shape, and to mount leaded components with various different lead separation distances on a board in a state bent into an N shape.
