Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laser processing heads lack a positioning mechanism, leading to deviations in the positional relationship between the tip end portion and the main body portion when they are separated and recoupled, affecting the processing accuracy.
Innovation Solution
A laser processing head with a first processing head unit and a second processing head unit, where the end portions facing each other are formed with inclined surfaces, and at least one of these surfaces is equipped with an attraction member and positioning pins and recesses to ensure accurate coupling and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the laser processing head is divided into separable first and second processing head units, then the impact force resistance is improved, but the positioning accuracy deteriorates
Solution Approach 1:
The laser processing head is divided into a first processing head unit and a second processing head unit that can be separably coupled. This segmentation allows the tip end portion to be separated from the main body portion when impact force exceeds the attraction force of the magnets, preventing damage to the laser processing head while maintaining positioning accuracy through positioning pins and recesses.
Solution Approach 2:
Positioning pins and recesses are introduced as intermediary elements between the first and second processing head units. These positioning mechanisms ensure accurate alignment and positioning when the units are coupled, preventing deviation in the positional relationship while allowing separable coupling for impact force protection.
2Productivity
If the processing head moves at high speed, then the productivity is improved, but the damage risk worsens
Solution Approach 1:
The laser processing head employs a dynamic coupling mechanism where the first and second processing head units are separably coupled through magnets. During high-speed movement, if collision occurs and impact force exceeds the attraction force, the units automatically separate, preventing damage while allowing continuous high-speed operation and maintaining reliability.

AI summary
A laser processing head includes first and second processing head units. An end portion of the first processing head unit facing the second processing head unit is formed with a first inclined surface. An end portion of the second processing head unit facing the first processing head unit is formed with a second inclined surface parallel to the first inclined surface. At least one of the first inclined surface or the second inclined surface is provided with an attraction member. At least one of the first inclined surface or the second inclined surface is provided with a positioning pin protruding toward the other thereof. At least the other of the first inclined surface or the second inclined surface is provided with a positioning recess into which the positioning pin is inserted. Each of the positioning pin and the positioning recess is plural in number.
