Problem

Existing workpiece insertion methods using vacuum suction and/or magnetic force can cause workpieces to assume unintended postures, leading to improper placement in carrier tape cavities and potential ejection during transport.

Innovation Solution

A workpiece insertion apparatus with an inclined surface, guide unit, and posture correction magnet that uses a combination of propulsive and magnetic forces to stabilize the workpiece posture, ensuring proper insertion into carrier tape cavities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If vacuum suction and/or magnetic force is used to insert a workpiece into a cavity of a carrier tape, then the workpiece can be inserted into the cavity, but the workpiece may assume an unintended posture (inclined posture) within the cavity

Engineering Contradiction:
Improveworkpiece insertionVSAvoidworkpiece posture
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The guide surface is provided in advance to cover the accommodation section and cavity, creating a predefined path and orientation guide for the workpiece before insertion occurs. This preliminary structural arrangement ensures the workpiece follows the correct trajectory and assumes the proper horizontal posture within the cavity, preventing unintended inclined postures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guide surface acts as an intermediary element between the workpiece and the cavity. It provides a physical guide that mediates the insertion process, directing the workpiece along a controlled path and ensuring proper orientation before the workpiece enters the cavity, thereby preventing unintended postures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a workpiece is not accommodated in a cavity in a proper orientation, then the insertion process is simple, but the top tape may not be properly applied to the carrier tape or the workpiece may jump out of the cavity when the carrier tape is moved

Engineering Contradiction:
Improveinsertion speedVSAvoidworkpiece stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The guide surface is pre-configured to define the correct insertion path and orientation before the workpiece is inserted. This preliminary arrangement ensures that even at high insertion speeds, the workpiece automatically assumes the proper horizontal posture, preventing subsequent issues like improper top tape application or workpiece ejection during carrier tape movement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guide surface serves as an intermediary that ensures reliable workpiece positioning without requiring complex slow-down mechanisms. It mediates between the speed of insertion and the need for proper orientation, allowing high productivity while maintaining reliability through the physical guidance provided by the guide surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the workpiece path is defined by the inclined surface and guide surface, then the workpiece can be guided to the cavity, but a propulsive force must be applied to move the workpiece along the inclined surface

Engineering Contradiction:
Improveworkpiece guidanceVSAvoidpropulsive force
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The inclined surface is designed to work in conjunction with the guide surface to create a self-aligning path for the workpiece. The inclination angle and guide surface geometry are coordinated to allow the workpiece to move along the path with minimal additional propulsive force, utilizing gravitational components and geometric guidance to reduce the required driving power.

Inventive Principle:
Principle #12Equipotentiality
