Laser Reflection Mirror Mounting for Continuous Cutting Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The laser reflection mirror in laser cutting apparatuses is prone to damage due to continuous exposure to the laser beam, leading to reduced positioning accuracy, light efficiency, and cutting quality.
Innovation Solution
A laser cutting apparatus with reinforced rigidity of the reflection mirror is designed, featuring a first fixing member with a first-1 filling member between it and the reflection mirror, and optionally a second fixing member with a second-1 filling member, to enhance the mirror's stability and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the laser reflection mirror is continuously exposed to the laser beam for positioning and reflection, then the laser cutting apparatus can perform continuous cutting operations, but the reflection mirror is at risk of damage or cracking due to the continuous moment and laser exposure
Solution Approach 1:
The patent applies beforehand cushioning by filling the space between the reflection mirror and the fixing member with a filling material (such as resin or adhesive) before operation. This filling material acts as a cushioning element that absorbs and distributes the continuous moment and thermal stress generated during laser exposure, preventing the mirror from cracking or detaching while maintaining continuous cutting capability
2Stability of the object's composition
If the reflection mirror is clamped by the fixing member to prevent damage, then the mirror's stability is improved, but the positioning accuracy and light efficiency decrease due to surface damage and misalignment
Solution Approach 1:
The patent applies local quality by designing the fixing member to clamp only a specific portion (edge or non-optical surface) of the reflection mirror rather than the entire surface. The filling material is applied locally in the clamping region to provide stability without affecting the optical surface quality or positioning accuracy of the mirror's reflective area
3Reliability
If the reflection mirror is securely fixed to prevent rotation and damage, then the mirror's reliability is improved, but the rigidity of the fixing structure decreases due to the rotating mechanism
Solution Approach 1:
The patent merges the fixing member and the support structure into an integrated assembly where the filling material bonds the mirror to the fixing member, which is itself structurally integrated with the support. This combined structure distributes mechanical loads more effectively, maintaining rigidity while allowing the necessary rotational movement for positioning, thereby preserving both reliability and strength
