Component Transfer Device Cam Mechanism Substrate Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component transfer devices are bulky and complex, requiring multiple actuators and long arm portions to handle substrates, which increases size and reduces efficiency and productivity.
Innovation Solution
A component transfer device with a holding mechanism and a pull-out unit that uses a cam mechanism with two arm members to grasp and release components at predetermined timings, simplifying the configuration and reducing the need for multiple actuators, while a restraint mechanism softens the grasping shock and prevents component drop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an arm portion is used to rake out the printed substrate by catching the innermost edge portion, then the substrate can be fetched from the substrate tote box, but the arm portion must be set longer than the substrate length dimension in the fetch direction, resulting in increased device size and complexity
Solution Approach 1:
Instead of having the arm portion rake out the substrate from the front by catching the innermost edge, the invention pushes the substrate from the rear side through a push-out portion. This reverses the fetching direction and method, allowing the arm to be shorter than the substrate length while still achieving effective substrate removal from the tote box.
Solution Approach 2:
The invention extracts only the necessary functional element (push-out portion) from the complex arm mechanism. By separating the pushing function from the fetching function and using a simple push-out structure rather than a long raking arm, the device achieves substrate fetching capability with reduced arm length and simplified driving mechanism.
2Productivity
If an arm portion is used to push out the printed substrate from the substrate tote box, then the substrate can be removed, but the arm portion must be set longer than the substrate length dimension in the thrusting direction, thereby increasing device size
Solution Approach 1:
The invention reverses the pushing approach by having the push-out portion act from the rear side of the substrate rather than from the front. This allows the push-out arm to be shorter than the substrate length while still effectively removing substrates from the tote box, as the pushing force is applied at the opposite end from conventional designs.
3Ease of operation
If an arm portion is used to sandwich the front side of the printed substrate from the vertical direction and pull it out, then the substrate can be fetched, but the configuration and driving mechanism required for this operation are not clear and cannot be specifically implemented
Solution Approach 1:
The invention extracts and simplifies the substrate fetching mechanism by using a push-out portion that acts from the rear side rather than implementing the complex vertical sandwiching and pulling mechanism. This provides a clear, implementable configuration that avoids the undefined complexity of the conventional vertical gripping approach.

AI summary
A component transfer device according to the present invention includes a holding mechanism that positions and holds a component on a carrying surface located at a predetermined height and a pull-out unit that pulls out the component held on the carrying surface by the holding mechanism in a horizontal direction. The pull-out unit includes a grasping member that can separably grasp the component from a vertical direction, a cam member that causes the grasping member to perform a component grasping operation and a component releasing operation at predetermined timings by exercising a cam function to the grasping member, a driving mechanism that drives the cam member and the grasping member, and a restraint mechanism that restrains a relative movement of the cam member with respect to the movable holder upon grasping operation.
