Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting machines require frequent replacement of chuck devices due to the limited size and shape capabilities, leading to increased costs and reduced productivity, as they need multiple types of chuck devices to accommodate different components.
Innovation Solution
A component mounting machine with a chuck device equipped with multiple types of chuck claws and a chuck claw switching mechanism using a cylindrical cam, allowing for independent upward and downward movement of chuck claws, which can be switched based on the component type, reducing the need for frequent device replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of chuck devices are prepared to accommodate different component sizes and shapes, then the adaptability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent implements a universal chuck device that can handle multiple component types by integrating multiple chuck claw types (first, second, and third chuck claws with different configurations) into a single device. The mounting head can switch between different chuck claw types based on component requirements, eliminating the need for multiple separate chuck devices and reducing device complexity while maintaining adaptability.
2Adaptability or versatility
If multiple types of chuck devices are prepared for different components, then the adaptability is improved, but the productivity is reduced due to frequent replacements
Solution Approach 1:
The patent prepares multiple types of chuck claws (first, second, and third chuck claws) in advance within the same chuck device, arranged at predetermined intervals around the cylindrical cam. The system can quickly switch between these pre-positioned chuck claw types without requiring physical replacement of the entire chuck device, thereby maintaining adaptability while preventing productivity loss from frequent replacements.
3Device complexity
If a single chuck device is used for all component types, then the device complexity is reduced, but the adaptability to different component sizes and shapes deteriorates
Solution Approach 1:
The patent segments the chuck device into multiple functional modules - specifically, multiple types of chuck claws (first, second, and third chuck claws) with different clamping characteristics are arranged at predetermined intervals around a cylindrical cam. This segmentation allows the single chuck device to provide diverse clamping capabilities for different component types while maintaining a unified device structure, thus reducing overall device complexity.
4Manufacturing precision
If chuck claws are moved independently upward and downward, then the clamping precision is improved, but the mechanism complexity increases
Solution Approach 1:
The patent introduces a cylindrical cam as an intermediary mechanism to control the independent upward and downward movement of different chuck claw types. The cam follower mechanism translates the rotation of the cylindrical cam into precise vertical movements of individual chuck claws, enabling independent positioning of each chuck claw type while maintaining a relatively simple overall structure, thus achieving high clamping precision without excessive mechanism complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the clamping of components of various sizes and shapes with a single chuck device, reducing replacement frequency, improving productivity, and minimizing the number of chuck devices required, thereby lowering costs and maintaining operational efficiency.
Implementation Method 1
the chuck claw switching mechanism is configured to use a cylindrical cam, the multiple types of chuck claws are arranged at predetermined intervals around the cylindrical cam, and a cam follower provided on each of the chuck claws is configured to fit into a cam groove in an outer peripheral surface of the cylindrical cam

AI summary
A chuck device is provided with multiple types of chuck claws clamping a component, a chuck claw switching mechanism switching the chuck claw in use among the multiple chuck claws based on the type of component to be clamped, and a driving mechanism causing the chuck claw subjected to the switching by a chuck claw switching mechanism perform a clamping operation. The chuck claw switching mechanism causes the respective chuck claws to move vertically independently of each other and performs switching of the chuck claw in use by a rotating cylindrical cam in a state where rotation of a tubular guide member placed on an outer peripheral side of a cylindrical cam is locked. A rotation locking member locking the rotation of the tubular guide member during switching of the chuck claw in use and a cam follower moving the rotation locking member are disposed in a mounting head.
