Solution Overview

Problem

Existing silicon bar machining devices are bulky, complex, and inefficient due to separate chamfer and plane grinding components, requiring a large layout and tri-axis manipulator movements, which increase device size and reduce machining precision.

Innovation Solution

A cutting-off and grinding integrated machine with juxtaposed cutting-off, feeding, and grinding components, and a manipulator moving in a single width direction, integrating chamfer and plane grinding components, and optimizing component layout to reduce device volume and simplify manipulator movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate chamfer grinding components and plane grinding components are used with independent layouts, then each grinding function can be performed independently, but the overall device size increases and structural compactness deteriorates

Engineering Contradiction:

Improvegrinding function independenceVSAvoiddevice size

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent combines separate chamfer grinding components and plane grinding components into an integrated grinding assembly. The chamfer grinding wheel and plane grinding wheel are mounted on the same manipulator arm, allowing both grinding functions to be performed by a single integrated structure rather than separate independent layouts, thereby reducing device size while maintaining functional independence.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The manipulator arm is designed with multi-functionality to perform multiple operations including crystal bar transfer, positioning, chamfer grinding, and plane grinding. This universal manipulator replaces what would traditionally require multiple specialized devices, achieving both functional versatility and compact structure through a single multi-functional robotic arm.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a tri-axis manipulator with complex movement structure is used, then the crystal bar can be transferred between multiple machining positions, but the device volume increases and structural compactness decreases

Engineering Contradiction:

Improvemanipulator movement capabilityVSAvoiddevice volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent merges multiple manipulator functions into a single robotic arm with integrated movement capabilities. Instead of using separate manipulators for transfer, positioning, and machining operations, a single robotic arm performs all these functions through coordinated movement, reducing the overall device volume while maintaining full operational capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The robotic arm is designed as a universal manipulator that can perform multiple machining operations including transferring the crystal bar, positioning it for cutting, performing chamfer grinding, and executing plane grinding. This multi-functional design eliminates the need for multiple specialized manipulators, achieving compact structure without sacrificing movement capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If the feeding component and blanking component are fixed in position, then the structure is simpler, but the machining precision and adaptability are reduced

Engineering Contradiction:

Improvecomponent layout simplicityVSAvoidmachining precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic positioning capabilities for both the feeding component and blanking component through movable platforms. The feeding platform can move along the X-axis to accommodate different crystal bar entry positions, and the blanking platform can move along the Y-axis to adjust discharge positions. This dynamic adjustability ensures high machining precision while maintaining relatively simple structural design.
