Component Mounting Machine Nozzle Exchange Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Component mounting machines face inefficiencies and interference issues when exchanging suction nozzles due to the fixed positioning of the nozzle station, which requires unnecessary head main body movements, especially when handling components of varying heights.
Innovation Solution
A component mounting machine with a station moving mechanism that adjusts its height position based on the head main body's position, using a control device to minimize interference and optimize nozzle exchange efficiency by positioning the station at either the lower or upper end depending on the head's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nozzle station is positioned at the upper end position to store exchange-use suction nozzles, then the suction nozzle exchange can be performed, but interference occurs between the tip of the suction nozzle and the nozzle station when the head main body is at the lower end position
Solution Approach 1:
The nozzle station is made movable in the vertical direction through a station raising and lowering mechanism, allowing it to dynamically change position between upper and lower end positions. This enables the system to adapt to different operational requirements: positioning at the upper end for storage and at the lower end for exchange operations, thereby eliminating interference while maintaining ease of operation.
2Object-affected harmful factors
If the nozzle station is positioned at the lower end position to avoid interference, then no interference occurs, but the head main body must be raised unnecessarily to the upper end for suction nozzle exchange
Solution Approach 1:
The station raising and lowering mechanism enables the nozzle station to be positioned at the lower end during normal operations and automatically raised to the upper end only when suction nozzle exchange is required. This dynamic positioning eliminates unnecessary head main body movements, reducing time loss while maintaining interference avoidance.
3Object-affected harmful factors
If the head main body is raised to the upper end for suction nozzle exchange, then interference is avoided, but the component mounting machine cannot efficiently handle low-height components
Solution Approach 1:
By making the nozzle station vertically movable, the system can maintain the head main body at the lower end position for efficient mounting of low-height components while the nozzle station is positioned at the upper end for storage. When exchange is needed, the nozzle station moves to the lower end temporarily, allowing exchange without raising the head main body, thus preserving productivity.
4Volume of moving object
If the nozzle station is positioned at the upper end position, then storage capacity is maximized, but the head main body must undergo longer travel distance for exchange operations
Solution Approach 1:
The station raising and lowering mechanism allows the nozzle station to be positioned at the upper end for maximum storage capacity during normal operations. When exchange is required, the nozzle station dynamically moves to the lower end, enabling the head main body to perform exchange operations with minimal travel distance, thus resolving the contradiction between storage capacity and operational efficiency.
