Rotary Mounting Head Nozzle Control for Shorter Pickup Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounters face inefficiencies in component pickup due to the need for significant rotation of pickup nozzles, which can lead to reduced mounting efficiency and productivity.
Innovation Solution
A component mounter with a rotary head and lifting/lowering device that allows pickup members to revolve and rotate, controlled to minimize the axis rotation of pickup members, enabling efficient component pickup at multiple angles with reduced moving distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pickup nozzle is rotated to coincide with a reference angle for component pickup, then the component can be picked up reliably, but the moving amount becomes great and mounting efficiency deteriorates
Solution Approach 1:
The pickup member is designed with dynamic rotation capability, allowing it to rotate about its own axis in addition to being revolved by the rotary head. This dynamic adjustment enables the pickup member to optimize its rotation angle for each component pickup, reducing unnecessary rotation movement while ensuring reliable component pickup.
Solution Approach 2:
The system changes the rotation angle parameter of the pickup member based on the specific component being picked up. By adjusting the rotation angle to match the component's orientation requirements, the system minimizes the rotation movement needed while ensuring reliable pickup, thereby improving both reliability and productivity.
2Adaptability or versatility
If multiple pickup nozzles are prepared for various component shapes, then different components can be picked up effectively, but the device complexity increases
Solution Approach 1:
The pickup member is designed with universal functionality to handle various component shapes. Instead of preparing multiple specialized pickup nozzles for different component types, a single pickup member can adapt to different components through rotation and positioning adjustments, reducing device complexity while maintaining versatility.
Solution Approach 2:
The pickup member incorporates dynamic rotation capability about its own axis, allowing it to adapt its orientation to match different component shapes and pickup requirements. This dynamic adjustment replaces the need for multiple fixed-purpose pickup nozzles, simplifying the device while maintaining adaptability to various component types.

AI summary
A component mounter includes a mounting head configured to revolve multiple nozzle holders to which multiple pickup nozzles can detachably be attached individually in a circumferential direction and to allow the multiple pickup nozzles to rotate on their own axes while being interlocked with each other and two Z-axis drive devices provided at two locations on a revolving orbit of the multiple pickup nozzles to raise and lower the pickup nozzles situated at the two locations. Then, when a component supplied from a component supply device can be picked up at any of multiple different nozzle angles of the pickup nozzle, the component mounter moves the pickup nozzle to a revolving angle at which the pickup nozzle can be raised and lowered and then lowers the pickup nozzle to pick up the component at a nozzle angle of the multiple nozzle angles which involves a smaller moving amount.
