Laser Optical Path Sealing for Dust-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser working machines fail to effectively prevent dust from entering the transmission optical paths between the machining head and both the laser oscillator and the torch, which can lead to contamination and maintenance issues.
Innovation Solution
The laser working machine incorporates a design with interchangeable shielding plates and light transmissive plates in the machining head's slots, maintaining a pressurized gas environment to prevent dust ingress, and includes a method for cleaning the shielded space during maintenance by using ventilating and discharge ducts to manage gas and impurities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single shielding plate is used to protect the optical path between the machining head and the laser oscillator, then dust entry into that specific path is prevented, but dust can still enter the optical path between the machining head and the torch
Solution Approach 1:
The optical path protection is segmented into multiple independent shielding plates: a first shielding plate for the optical path between the machining head and the laser oscillator, and a second shielding plate for the optical path between the machining head and the torch. Each shielding plate independently protects its respective optical path, ensuring comprehensive dust prevention across all optical paths.
2Reliability
If shielding plates are installed in all slots to prevent dust entry, then dust protection is improved, but maintenance and cleaning operations become more difficult
Solution Approach 1:
The shielding plates are designed to be selectively installable and removable from the slots. During normal operation, shielding plates are installed to prevent dust entry. During maintenance, the shielding plates can be removed to provide access for cleaning and servicing. This dynamic configuration allows the system to switch between protection mode and maintenance mode.
Solution Approach 2:
The shielding plates are pre-positioned in the slots during assembly, providing immediate dust protection. The design anticipates future maintenance needs by making the shielding plates removable, so that when maintenance is required, the plates can be taken off without modifying the overall structure.

AI summary
A laser working machine includes a first slot provided at another end portion of a first body. In the first slot, a first shielding plate and a first light transmissive plate are selectively insertable in a sealed manner. The first shielding plate is for shielding a first optical path. The first light transmissive plate has a first optical path hole through which the first optical path and a second optical path are connectable to each other. The laser working machine includes a second slot provided at a second body end portion of a second body. In the second slot, a second shielding plate and a second light transmissive plate are selectively insertable in a sealed manner. The second shielding plate is for shielding the second optical path. The second light transmissive plate has a second optical path hole through which the first optical path and the second optical path are connectable to each other.
