Component Mounter Nozzle Exchange Angle Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of nozzle tool exchange processing in component mounters is hindered by the need for angle alignment, which depends on the rotation angle, limiting the speed of exchange operations.
Innovation Solution
A component mounter with a tool station capable of storing nozzle tools at multiple different storage angles, combined with a control device that acquires and aligns these angles for efficient exchange, allowing the nozzle tool to be aligned with the head main body at zero or a small rotation angle, thereby reducing the time required for exchange processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If angle alignment is performed during nozzle tool exchange processing, then the nozzle tool can be properly positioned for mounting operations, but the exchange processing time increases due to rotation angle requirements
Solution Approach 1:
The tool station pre-aligns nozzle tools at storage angles that match the head main body's orientation requirements. By performing the alignment action in advance during storage rather than during exchange, the system eliminates rotation time during actual tool exchange while maintaining precise angle alignment when needed
Solution Approach 2:
The system changes the storage angle parameter of nozzle tools in the tool station to match the required mounting orientation. By adjusting the storage angle parameter to coincide with the head main body's operational angle, the system eliminates the need for additional rotation during exchange, thereby reducing exchange time while maintaining alignment precision
2Device complexity
If the tool station stores nozzle tools at a fixed single angle, then the storage structure is simple, but the exchange efficiency is reduced due to required rotation operations
Solution Approach 1:
The tool station is designed with dynamic angle adjustment capability, allowing storage angles to be changed based on the specific nozzle tool and mounting requirements. This dynamic adaptability enables the system to optimize exchange efficiency by matching storage angles to operational needs without significantly increasing structural complexity
Solution Approach 2:
The tool station is designed to accommodate nozzle tools at multiple different storage angles, making it universally applicable to various tool types and mounting orientations. This multi-functional capability allows a single tool station to handle diverse tool exchange scenarios without requiring separate dedicated stations for each angle

AI summary
A component mounter includes a component transfer device, a tool station, and a control device. The component transfer device is provided with a head main body, and a tool holding device configured to hold a nozzle tool and provided to be raisable and lowerable with respect to the head main body and rotatable around a rotation axis line. The tool station is configured to be able to store an exchange-use nozzle tool at multiple different storage angles. The control device of the component mounter includes an angle acquiring section that acquires the storage angle of the exchange-use nozzle tool in the tool station, and an exchange control section that, during the nozzle tool exchange processing, rotates the tool holding device based on the storage angle of the nozzle tool, and performs angle alignment of the nozzle tool with respect to the head main body.
