Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bulk feeders with fixedly connected suction nozzles face challenges in aligning the supply position and holding position of electronic components due to movement, leading to misalignment issues during component pickup.
Innovation Solution
A bulk feeder with a flexible connecting section and an actuator that allows the supply passage to adjust its position, enabling correction of the supply position using a control device and piezoelectric elements to align the holding and supply positions, even when the feeder is moved with a mounting head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bulk feeder is fixedly connected to a mounting head with suction nozzles and moved together by a moving device, then the mounting head can be positioned at any location, but the supply position and holding position of electronic components cannot be aligned due to movement
Solution Approach 1:
The supply passage is divided into multiple block sections (first block section, second block section, etc.) connected by flexible connecting sections. This segmentation allows independent adjustment of each block section's position while maintaining overall supply passage functionality, enabling alignment correction without affecting the entire feeder system.
Solution Approach 2:
The bulk feeder transitions from a fixed rigid structure to a dynamic adjustable structure. The first block section is made movable relative to the second block section through flexible connecting sections, allowing real-time position adjustment to maintain alignment between supply and holding positions during mounting head movement.
2Stability of the object's composition
If the supply passage is made rigid and fixed, then the structure is simple and stable, but the supply position cannot be adjusted to align with the holding position when the feeder moves
Solution Approach 1:
The supply passage incorporates movable block sections connected by flexible joints, transforming the rigid structure into a dynamically adjustable one. This allows the supply position to be corrected while maintaining overall structural stability through the connected block sections.
Solution Approach 2:
The position parameters of block sections within the supply passage are made changeable. By adjusting the position of the first block section relative to the second block section, the supply position can be modified to align with the holding position while the overall supply passage maintains its structural integrity.
3Adaptability or versatility
If the bulk feeder is moved together with the mounting head, then the system integrates well, but various alignment methods must be investigated to maintain proper positioning
Solution Approach 1:
The supply passage is segmented into adjustable block sections that can independently correct position deviations. This localized adjustment mechanism is simpler than correcting the entire feeder system, reducing overall device complexity while maintaining system integration.
Solution Approach 2:
The bulk feeder incorporates self-correction capability through movable block sections that can automatically adjust the supply position to align with the holding position. This self-service alignment mechanism reduces the need for external complex alignment systems.

AI summary
For a bulk feeder for supplying electronic components to a supply position which is provided with a storage section for storing multiple electronic components in a loose state and a supply passage for guiding the electronic components stored in that storage section to an electronic component supply position while arranged in a single line, a section of the supply passage is a section which has flexibility and groove block member 172 which includes an electronic component supply position is moved using the flexibility of that section with flexibility. By this, it is possible to perform correction of the supply position and it is possible to suitably align the electronic component holding position and supply position.
