Visual Laser Engraving Layout for Uniform Multi-Surface Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser engraving machines face challenges in maintaining consistent surface heights during multi-surface engraving, leading to inconsistent effect presentation, and they lack effective smoke management to prevent airborne particles from being absorbed by humans.
Innovation Solution
A visual laser engraving machine is designed with a portal frame, horizontal and longitudinal slide rails, electrically controlled pulleys, servo motors, and miniature push rods to adjust the product's height and rotate it for consistent engraving, along with fans and an activated carbon plate to manage smoke and dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the product is rotated to engrave multiple surfaces, then all surfaces can be engraved, but the engraved surfaces become inconsistent in height
Solution Approach 1:
The patent implements a dynamic height adjustment mechanism where each product surface can be independently positioned at the correct height using electric push rods and servo motors. This allows the system to adapt to different surface orientations while maintaining consistent engraving height, resolving the contradiction between multi-surface capability and height consistency.
Solution Approach 2:
The system changes the height parameter of each product surface dynamically during the engraving process. By using infrared distance meters to detect surface positions and adjusting heights through electric push rods, the system maintains optimal engraving parameters for each surface regardless of its orientation.
2Productivity
If laser engraving is performed on multiple surfaces, then complete product marking is achieved, but smoke accumulates and can be inhaled
Solution Approach 1:
The patent converts the harmful smoke by designating a specific surface as a smoke discharge surface and using fans to direct smoke away from the operator. The harmful smoke is transformed into a controlled exhaust flow that is safely vented, turning a health hazard into a manageable byproduct of the multi-surface engraving process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine ensures all surfaces are engraved at the same height, improving presentation consistency and effectively filters smoke and dust particles, preventing them from floating and being inhaled.
Implementation Method 1
an infrared distance meter is arranged on an outer side surface of the laser device
Implementation Method 2
the product body is driven by the electric push rods to ascend or descend
Implementation Method 3
The laser beams may produce chemical effects and physical effects on materials. Physical or chemical reaction occurs after the materials absorb laser light instantly
Implementation Method 4
the materials absorb laser light instantly, thereby engraving marks
Implementation Method 5
smoke generated during engraving is blown downwards by the first fan and the second fan
Implementation Method 6
the smoke sinks and penetrates through the activated carbon plate to be adsorbed and filtered
