Problem
Existing devices for connecting flexible boards to wiring boards with high-density mounted components face challenges in low-load bonding due to increased size and weight, making them unsuitable for limited connection regions.
Innovation Solution
An electric components connection device comprising two units with adjustable suction and support mechanisms, allowing for height and position changes to reduce the size and weight of the connecting unit, enabling low-load bonding of flexible boards to wiring boards with high-density components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a drive system is provided for the second holding portion to change the height of the other connection region, then the shape of the flexible board can be changed, but the size and weight of the conveying head are increased
Solution Approach 1:
The device is divided into two separate holding portions (first holding portion and second holding portion) that can be independently controlled. The drive system is specifically assigned to the second holding portion, allowing height adjustment of only the other connection region while keeping the first holding portion relatively simple. This segmentation enables shape change capability without requiring the entire conveying head to be heavily equipped with drive systems.
Solution Approach 2:
The second holding portion is equipped with a drive system that can dynamically change the height position of the other connection region. This dynamic adjustment capability allows the flexible board to be deformed into various shapes during the connection process, enabling adaptation to different connection scenarios while maintaining a relatively compact overall structure.
2Adaptability or versatility
If a drive system is provided for the second holding portion to change the height of the other connection region, then the shape of the flexible board can be changed, but the size of the conveying head is increased
Solution Approach 1:
The conveying head is segmented into two independent holding portions, with the drive system concentrated in the second holding portion. This segmentation allows the first holding portion to maintain a compact size while the second holding portion provides the necessary height adjustment capability, reducing the overall volume compared to a fully equipped single holding portion.
Solution Approach 2:
By providing dynamic height adjustment only where needed (in the second holding portion), the device achieves shape change capability without requiring excessive volume throughout the entire conveying head. The dynamic drive system enables precise local adjustment rather than requiring global structural changes.
3Measurement precision
If the first holding portion and the second holding portion serve as a conveying head for transporting the flexible board, then alignment can be performed, but the device is not suitable for connection operations in the vicinity of limited connection regions with high packaging density
Solution Approach 1:
The conveying head is divided into two independent holding portions that can be controlled separately. This segmentation allows precise alignment to be achieved through coordinated movement of both portions, while the overall structure remains compact enough to access limited connection regions with high packaging density. The independent control of each portion enables fine-tuned positioning without requiring a large overall structure.

AI summary
A connection device for an electric component 4 is constituted by two units 2 and 3, height position change means that changes the height position of one end 4a of the electric component 4 relative to the other end 4b is provided for a second unit 3, and the size and weight of a first unit 2 that connects the electric component 4 to a wiring board can be reduced. Therefore, the electric component 4 can be connected, under a low load, to a limited connection region of a wiring board.
