Separate Mounting and Pressing Heads for Fitting Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting devices face instability in both moving and mounting operations due to the need for varying rigidity and strength in holding units, leading to potential deformation and positional interference when transitioning between these operations for fitting components.
Innovation Solution
A component mounting device with separate moving and mounting heads, utilizing a holding unit for precise component placement and a pressing unit for applying a consistent pushing force, allowing for stable execution of both operations without compromising positional accuracy or stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single holding unit is used for both moving and mounting operation and pushing operation, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to deformation and positional interference
Solution Approach 1:
The invention divides the mounting head into two separate functional units: a holding unit for moving and mounting operations, and a pressing unit for pushing operations. This segmentation allows each unit to be optimized independently - the holding unit for precision positioning and the pressing unit for applying force, thereby resolving the contradiction between device simplicity and manufacturing precision.
Solution Approach 2:
The invention applies different structural properties to different parts of the mounting head. The holding unit is designed with high rigidity and precision for accurate component placement, while the pressing unit is designed to apply sufficient pushing force. This local differentiation of functional qualities resolves the contradiction by giving each unit the specific properties it needs for its designated task.
2Reliability
If pressing force is increased to ensure fitting accuracy, then reliability of pushing operation is improved, but manufacturing precision deteriorates due to deformation of the holding unit
Solution Approach 1:
By separating the pressing function into an independent pressing unit, the invention allows the holding unit to maintain its precision positioning capability while the pressing unit applies the necessary force. The pressing unit can be designed with sufficient strength to apply high pressing force without affecting the holding unit's positioning accuracy, thus resolving the contradiction between reliability and manufacturing precision.
3Strength
If the size of the holding unit is increased to increase rigidity, then strength is improved, but positional interference with other components occurs
Solution Approach 1:
The invention separates the pressing function into a dedicated pressing unit that can be positioned independently from the holding unit. This allows the holding unit to be compact in size for precise positioning, while the pressing unit can be deployed only when needed for pushing operations, thereby reducing spatial interference with other components while maintaining sufficient strength for the pushing task.
4Ease of operation
If a common holding unit is used for moving and mounting and pushing operations, then ease of operation is improved, but reliability deteriorates due to insufficient strength and deformation
Solution Approach 1:
The invention divides the mounting head into specialized holding and pressing units, with each unit optimized for its specific function. This segmentation improves reliability by giving each unit the structural properties it needs - the holding unit for precision and the pressing unit for force application. The integrated design maintains ease of operation through automated coordination between the two units.
Solution Approach 2:
The mounting head is designed as a universal platform that integrates multiple functions: the holding unit performs moving and mounting operations, while the pressing unit performs pushing operations. This multi-functional integration maintains operational simplicity while improving reliability through specialized sub-units.

AI summary
A component mounting device which mounts on a board electronic components including 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 moving and mounting head which holds and takes out the fitting component by a holding unit from a component supply part to move and mount the fitting component on the to-be-attached part of the board, and a pressing head which presses the fitting component that is moved and mounted on the to-be-attached part by a pressing unit to attach the fitting component to the to-be-attached part.
