Nozzle Station Layout for Faster Suction Nozzle Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work machines that use multiple holding tools face inefficiencies in exchanging these tools, leading to prolonged cycle times, which hinders the reduction of overall processing time.
Innovation Solution
A work machine with a control device that allows for the pre-attachment of holding tools to the work head and subsequent return to predetermined placement sections at the holding tool station, optimizing the arrangement of tools to minimize exchange time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holding tools are exchanged between work head and holding tool station, then multiple holding tools can be used for work, but the time spent exchanging holding tools increases
Solution Approach 1:
The control device pre-arranges holding tools in specific placement positions on the holding tool station before work begins. This preliminary arrangement ensures that when tool exchange is needed, the work head can quickly acquire the required tool from its predetermined position without searching or repositioning, thereby reducing exchange time while maintaining the ability to use multiple different holding tools
2Ease of operation
If holding tools are randomly placed on holding tool station, then exchange operation is simple, but time required for exchange increases due to misalignment
Solution Approach 1:
Different placement positions on the holding tool station are assigned different functions based on the work requirements. The control device designates specific positions as set placement positions for tools that will be frequently used or need quick access. This local differentiation of placement positions optimizes the exchange process by ensuring tools are always returned to and retrieved from their most efficient positions, reducing overall exchange time while maintaining operational simplicity

AI summary
In mounter, work using multiple suction nozzles is executed by executing an exchange of suction nozzles between nozzle station and mounting head. In addition, placement positions of suction nozzles at nozzle station are set so that the distance between accommodation section at the nozzle station and part camera is shorter for the suction nozzle to be exchanged more times at the nozzle station. Then, for exchange of suction nozzles during mounting work, the suction nozzle attached to the mounting head is returned to a placement section corresponding to a set placement position. As a result, placement positions at the nozzle station are rearranged into the set placement positions, so that the distance that the mounting head moves for nozzle exchange can be made shorter, which makes it possible to reduce the time required for nozzle exchange.
