Carrier Tape Support Spring Structure for Stable Component Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component supply apparatuses face difficulties in providing a sufficient urging force to the tape, leading to issues such as depression or inclination of the tape during component adsorption, which adversely affects the component adsorption process.
Innovation Solution
The component supply apparatus incorporates a wire spring member that extends between the leaf spring member and the main body, providing an additional urging force to the tape. This configuration ensures that the tape is stably supported and urged upward at the component supply position, enhancing the component supply process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If only a leaf spring member is used to support the tape, then the structure remains simple, but the urging force applied to the tape is insufficient causing depression and inclination
Solution Approach 1:
The patent combines the leaf spring member and wire spring member into a composite urging mechanism. The leaf spring member provides baseline support while the wire spring member adds supplementary urging force, merging two spring mechanisms to achieve sufficient total urging force without excessive complexity
Solution Approach 2:
The urging mechanism is segmented into two functional parts: the leaf spring member that provides continuous support along the tape width, and the wire spring member that provides focused urging force at specific positions. This segmentation allows each component to be optimized for its specific function while working together
2Force
If the leaf spring member is made stronger to increase urging force, then the urging force improves, but the risk of damaging the tape or component increases
Solution Approach 1:
The wire spring member is positioned to apply urging force locally at specific critical positions where the tape needs support, rather than applying force uniformly across the entire tape. This localized application provides necessary urging force while minimizing the risk of widespread tape damage
Solution Approach 2:
The wire spring member is designed with dynamic characteristics that allow it to flex and adjust its force application. The spring can compress and expand dynamically, providing varying levels of force depending on the tape's position and condition, thereby preventing both insufficient urging and excessive force that could damage the tape
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
The enhanced urging force provided by the wire spring member ensures stable and efficient component supply, reducing the likelihood of tape depression or inclination and improving the overall operation rate of the component mounting apparatus.
Implementation Method 1
an urging member disposed between the leaf spring member and the opposed surface so as to urge the leaf spring member upward
Implementation Method 2
a center portion curved upward so as to support the lower surface of the tape while urging the lower surface of the tape upward

AI summary
A component supply apparatus includes a sending part configured to send tape housing a component therein in a sending direction so as to supply the component to a component supply position; a main body having an opposed surface extending in the sending direction, which faces a lower surface of the tape being sent by the sending part; a leaf spring member extending in the sending direction and having both end portions in contact with the opposed surface and a center portion curved upward so as to support the lower surface of the tape while urging the lower surface of the tape upward at the component supply position; and an urging member disposed between the leaf spring member and the opposed surface so as to urge the leaf spring member upward.
