Adjustment Jig Aligning Nozzle Holders for Precision Die Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face challenges in accurately aligning multiple suction nozzles between a die supply device and a component mounter, which is crucial for transferring multiple dies simultaneously, due to the need for precise positional matching of these nozzles, especially when dealing with small components.
Innovation Solution
An adjustment jig with pin members and a board configuration that allows for the alignment of nozzle holders on both the supply head and mounting head, enabling precise matching of nozzle positions using a primary and secondary side process, ensuring accurate transfer of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple suction nozzles are used to transfer multiple dies at a time, then productivity is improved, but alignment precision between nozzle holders deteriorates due to the complexity of matching positions
Solution Approach 1:
The patent introduces a jig as an intermediary tool that mediates the alignment between the first and second nozzle holders. The jig contains multiple positioning holes that correspond to the nozzle positions, enabling precise alignment through mechanical insertion rather than direct matching between the two nozzle holders. This intermediary device simplifies the alignment process while maintaining high precision.
Solution Approach 2:
The nozzle holders are designed with self-aligning features where insertion sections fit into the positioning holes of the jig. The structural design allows the components to self-align through their geometric constraints, reducing the need for complex external alignment mechanisms and enabling operators to achieve precise alignment through simple insertion operations.
2Device complexity
If traditional alignment methods are used for nozzle holders, then device complexity is reduced, but alignment time increases due to the manual and repetitive nature of the process
Solution Approach 1:
The jig is pre-configured with positioning holes at the exact locations corresponding to the nozzle positions. This preliminary preparation of the alignment tool allows for rapid alignment during operation, as the positions are already determined and encoded in the jig's structure, eliminating the need for time-consuming measurement and calculation during the alignment process.
Solution Approach 2:
The jig serves as a reusable intermediary tool that encapsulates the alignment knowledge and geometry. Once the jig is manufactured with the correct positioning holes, it can be used repeatedly for aligning multiple nozzle holders, significantly reducing the time required for each alignment operation while maintaining consistency across all alignments.

AI summary
An adjustment jig for performing position alignment of nozzle holders, including: multiple positioning pins including a primary insertion section configured such that multiple nozzle holders of a primary side device are insertable into the primary insertion section and a secondary insertion section configured such that multiple nozzle holders of a secondary side device are insertable into the secondary insertion section; and a board member configured such that the multiple positioning pins protruding to an opposite side to the primary insertion section and the secondary insertion section can be attached at a specified fixing position via a fixing section, a position of which is adjustable.
