Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face challenges in accurately aligning the positions of 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 alignment of small components.
Innovation Solution
An adjustment jig with positioning pins and a board member is used to align the nozzle holders of the supply head and mounting head, allowing for adjustable fixation and alignment of the nozzle holders on both devices, ensuring accurate positional matching.
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 manufacturing precision deteriorates due to the complexity of aligning multiple nozzle holders
Solution Approach 1:
The patent introduces a bridge structure as an intermediary component between the first and second nozzle holders. This bridge provides reference surfaces that mediate the alignment process, allowing both nozzle holders to be positioned accurately relative to each other through the bridge's reference surfaces, thereby maintaining high alignment precision while enabling multi-component transfer
Solution Approach 2:
The patent implements preliminary alignment actions by providing reference surfaces on the bridge structure before the actual nozzle holder positioning. The reference surfaces pre-establish the spatial relationship and orientation, so that when nozzle holders are attached, their positions are automatically determined with high precision, eliminating complex real-time alignment operations
2Manufacturing precision
If manual alignment operations are performed to match nozzle holder positions, then manufacturing precision can be maintained, but loss of time increases due to the complexity of the alignment work
Solution Approach 1:
The patent enables self-aligning functionality through the bridge structure's reference surfaces. When nozzle holders are attached to the bridge, their positions are automatically determined by the reference surfaces without requiring complex manual alignment operations. The system essentially aligns itself through the geometric constraints provided by the reference surfaces, dramatically reducing alignment time while maintaining precision
Solution Approach 2:
The reference surfaces are pre-configured on the bridge structure with precise geometries that define the correct positions and orientations. This preliminary preparation of alignment references eliminates the need for time-consuming manual measurement and adjustment during assembly, allowing rapid and accurate positioning of nozzle holders
3Productivity
If multiple nozzle holders are used for transferring multiple components, then productivity is improved, but device complexity increases due to the need for multiple positioning reference surfaces
Solution Approach 1:
The patent combines multiple positioning reference surfaces into a single integrated bridge structure. Instead of providing separate reference surfaces for each nozzle holder that would increase complexity, the bridge merges all reference functions into one component, reducing the total number of parts while still enabling precise positioning of multiple nozzle holders
Solution Approach 2:
The bridge structure serves multiple functions simultaneously: it acts as a structural support, provides reference surfaces for both first and second nozzle holders, and establishes the spatial relationship between them. This multi-functionality reduces the need for separate components for each function, thereby reducing overall device complexity while maintaining the capability to handle multiple components
