Solution Overview

Problem

The existing substrate bottom reception systems that use magnetic force to fix bottom reception pins are inefficient in automating the rearrangement of pins due to the need for a mechanical chuck mechanism with high holding force, leading to a complex device structure and labor-intensive manual operations.

Innovation Solution

A bottom reception pin module with a magnet member that can be freely lifted and lowered, allowing the pins to be fixed and unfixed from the base by a magnetization force, enabling efficient automation of pin arrangement changes with a simple structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a mechanical chuck mechanism with large holding force is used to automate pin rearrangement, then the pin arrangement changing operation can be automated, but the device structure becomes complicated

Engineering Contradiction:

Improvepin arrangement changing operationVSAvoiddevice structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical chuck mechanism with a magnetic field-based fixing system. Magnets are embedded in the bottom reception base part to fix the bottom reception pins through magnetic attraction, eliminating the need for complex mechanical chuck mechanisms while enabling automated pin arrangement changes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the magnetic fixing function from the mechanical chuck mechanism, separating the pin fixing function from the mechanical holding structure. This allows the pin arrangement changing operation to be automated through magnetic field control without requiring the complex mechanical chuck system

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If the nozzle clamp force is increased to move bottom reception pins, then the pins can be moved by the mounting head, but the fixing force required to hold pins stably increases beyond the nozzle clamp force

Engineering Contradiction:

Improvepin moving operationVSAvoidfixing force

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The patent replaces the mechanical force-based fixing system with a magnetic field-based system. Magnets embedded in the bottom reception base part provide stable fixing force through magnetic attraction, which is independent of the nozzle clamp force, allowing easy pin moving operation without requiring excessive fixing force

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If manual operation is used for pin rearrangement, then the device structure remains simple, but labor requirements increase and efficiency decreases

Engineering Contradiction:

Improvedevice structureVSAvoidefficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical operations with an automated magnetic field-based system. The magnetic fixing mechanism allows the mounting head to automatically move and rearrange pins without manual intervention, significantly improving efficiency while keeping the overall device structure relatively simple

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A bottom reception pin module 22 which is allowed to stand upright on a bottom reception base part 21 having a magnetic member 21a provided on an upper surface to support the substrate includes a base part 23 having a magnet member 26 built therein so as to be freely lifted and lowered and fixed to the bottom reception base part 21 by a magnetization force under a state that the magnet member 26 is lowered and a hollow shaft member 24 extended upward from the base part 23 and having an upper end of a top member 25 abutting on the lower surface of the substrate to support the substrate. By a vacuum suction from a suction hole 25c, the magnet member 26 is lowered and lifted to fix and unfix the base part 23 relative to the bottom reception base part 21.
