Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounter systems face inefficiencies due to the need for multiple head modules for high-speed and multifunctional applications, leading to reduced production efficiency and potential damage during nozzle replacement, as they lack adaptive air flow rate control for varying part sizes and types without stopping operations.
Innovation Solution
A mounter air controller with a flow rate adjustment mechanism and control means that adjusts air flow based on applied voltage or current, allowing continuous adjustment of air flow rates between positive and negative pressure regions, enabling a single head module to handle multiple types of parts and nozzles without stopping the mounter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple head modules are used for high-speed and multifunctional applications, then the mounter can handle different part types effectively, but the device complexity increases and production efficiency decreases
Solution Approach 1:
The patent implements a universal head module design that can handle both high-speed small chip mounting and multifunctional large component mounting through a single device. This is achieved by integrating adjustable air flow rate control mechanisms that adapt to different nozzle configurations and part types, eliminating the need for multiple specialized head modules while maintaining versatility across different mounting applications
2Reliability
If multiple head modules are used for different applications, then each application can be optimized, but the facility operation rate decreases due to replacement downtime
Solution Approach 1:
The patent employs dynamic air flow rate adjustment capabilities that allow the single head module to adapt its performance characteristics in real-time based on the specific application requirements. The control system modifies air flow rates dynamically to optimize for either high-speed small chip mounting or precise large component handling, enabling one head module to replace multiple specialized modules without requiring physical replacement or downtime
3Ease of operation
If fixed air flow rate control is used, then the system is simple to operate, but it causes damage during nozzle replacement and cannot adapt to different part sizes
Solution Approach 1:
The patent implements variable air flow rate control that adjusts the air flow parameters based on the specific nozzle and part configuration being used. The system provides different air flow rates for different applications: lower air flow rates for high-speed small chip mounting and higher air flow rates for large component handling. This parameter adjustment capability prevents damage during nozzle replacement while maintaining ease of operation through automated control

AI summary
The present invention provides a mounter air controller capable of executing appropriate air control associated with replacement of a nozzle without stopping operation of a mounter. This mounter air controller includes: a flow rate adjustment mechanism 4 mounted on a head module HM of the mounter; and control means 5 that controls this flow rate adjustment mechanism 4. The flow rate adjustment mechanism 4 is interposed between a positive-pressure region and a nozzle n and has a function capable of continuously changing a flow rate of passing air. The control means 5 is configured to bring the nozzle n to have a negative pressure and then control the flow rate in the flow rate adjustment mechanism 4 on the basis of an applied voltage or an applied current, which is determined in advance, so as to supply the air to the nozzle n.
