Dual-Load Mounting Head for Shield Cover Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting devices face issues with bending deformation of thin components like shield covers during attachment, leading to interference and damage due to inconsistent loading during moving and pushing operations.
Innovation Solution
A component mounting device with a dual-load system, where a first load is used for moving and mounting, and a second, higher load for pressing, with the mounting head controlled to suck and hold the central portion of the component for stable operation, and a separate pressing unit applies the second load to attach the component securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same holding unit is used for both moving and pushing operations, then the device complexity is reduced, but the component reliability deteriorates due to bending deformation and damage
Solution Approach 1:
The patent divides the mounting head into two separate units: a holding unit with suction nozzles for moving and mounting operations, and a pressing unit with a press part for pushing operations. This segmentation allows each unit to be optimized for its specific function, preventing bending deformation during movement and ensuring reliable attachment during pushing, thereby resolving the contradiction between device complexity and component reliability.
2Force
If a large load is applied during moving and mounting operation, then the component can be securely held, but the component shape deteriorates due to bending deformation of thin components
Solution Approach 1:
The patent separates the holding function (using suction force on the upper surface) from the pressing function (using mechanical force on the lower surface). During moving and mounting, only the holding force is applied through the holding unit, which securely holds thin components without causing bending. The pressing unit is activated only after positioning, applying force only when needed for attachment, thus preventing shape deterioration while maintaining secure holding.
3Strength
If the pressing operation is performed with insufficient load, then the component damage is reduced, but the attachment reliability deteriorates due to improper fitting
Solution Approach 1:
The patent implements dynamic load control where the pressing load is adjusted based on the operational phase. During moving and mounting, the holding unit applies a first load sufficient for secure transport. During the pushing operation, the pressing unit applies a second load that is optimized for proper fitting and attachment. This dynamic adjustment ensures attachment reliability without excessive force that could damage the component.
4Stability of the object's composition
If the holding position is at the central portion, then the component stability is improved during movement, but the pressing effectiveness deteriorates due to load distribution issues
Solution Approach 1:
The patent segments the holding and pressing functions into separate units with different positioning strategies. The holding unit positions its suction nozzles at the central portion of the upper surface, providing stable holding during movement. The pressing unit positions its press part at the lower surface corresponding to the to-be-attached part, ensuring effective pressing for attachment. This spatial segmentation allows both central holding for stability and targeted pressing for precision without interference.

AI summary
A component mounting device that mounts on a board a fitting component to be attached by a mechanical fitting or engagement to a to-be-attached part formed in the board. The component mounting device includes a mounting head which carries out a moving and mounting operation in which the fitting component is taken out from a component supply part by sucking and holding the fitting component, moved and mounted on the to-be-attached part, and pressed by a first load, and a pressing operation in which the fitting component is pressed by a second load larger than the first load, and a head control part which controls the mounting head to suck and hold a neighborhood of a central portion of an upper surface of the fitting component in the moving and mounting operation, and to press a press part corresponding to the to-be-attached part in the pressing operation.
