Inverting Head Horizontal Swaying for Compact Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting apparatuses require a large distance between the substrate and the mount head to position a component inverted upside down, leading to increased apparatus size and potential accuracy issues during mounting.
Innovation Solution
A component mounting apparatus with an inverting head featuring a flat-plate-like base, swayable nozzle holder support member, and a turnable nozzle holder that allows the nozzle to switch orientation, enabling a shorter down-stroke and compact design by eliminating vertical movement and swaying mechanisms above and below the nozzle holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional inverting head with vertical movement and swaying mechanisms is used, then the component can be inverted and transferred, but the distance between substrate and mount head must be large, increasing apparatus size and reducing mounting accuracy
Solution Approach 1:
The patent repositions the swaying mechanism from vertical to horizontal plane. The nozzle holder support member sways horizontally rather than vertically, allowing the inverting head to maneuver around the substrate-mound head space without requiring large vertical clearance. This dimensional change enables the system to achieve the same component inversion and transfer function while minimizing the distance between substrate and mount head.
Solution Approach 2:
The patent inverts the conventional approach by having the nozzle holder itself sway horizontally rather than having the entire inverting head move vertically. This reversal of the movement mechanism allows for a more compact configuration where the component inversion is achieved through horizontal swaying and rotation of the nozzle holder, eliminating the need for large vertical spaces.
2Adaptability or versatility
If vertical movement mechanism is included in the inverting head, then component inversion is achieved, but the apparatus size increases due to longer down-stroke requirement
Solution Approach 1:
The patent replaces vertical movement with horizontal swaying. The nozzle holder support member sways horizontally within the plane, and the nozzle holder rotates horizontally, enabling component inversion through horizontal dimensional changes rather than vertical movement. This eliminates the need for long down-stroke while maintaining component inversion capability.
Solution Approach 2:
The patent substitutes the vertical mechanical movement system with a horizontal swaying and rotation system. Instead of using vertical actuators to move the inverting head up and down, the system uses horizontal swaying of the nozzle holder support member and horizontal rotation of the nozzle holder, achieving the same functional result with a different mechanical approach that requires less travel distance.
