Solution Overview
Problem
Existing laser beam machine conveyors experience excessive thermal deformation due to the irradiation of laser beams, hindering smooth movement of transportation plates and affecting the efficiency of dross removal.
Innovation Solution
Incorporation of a concave portion in the transportation plates, specifically designed to minimize thermal deformation by counteracting the deflection caused by laser beam irradiation, allowing for smoother movement and efficient dross transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transportation plates are used to transport dross under laser beam irradiation, then dross removal efficiency is improved, but thermal deformation occurs causing movement obstruction
Solution Approach 1:
The transportation plate incorporates a concave portion at its rear end with a specific depth (0.5-2.0mm) to create localized thermal management. This concave structure allows differential thermal expansion where the rear end can deform independently from the front end, maintaining overall plate functionality while accommodating thermal effects in the specific region most affected by laser irradiation.
Solution Approach 2:
The concave portion introduces a curved geometric feature at the rear end of the transportation plate. This curvature creates a flexible zone that can thermally deform without obstructing movement, as the curved geometry naturally accommodates expansion and contraction better than a flat rigid surface would.
2Ease of manufacture
If the transportation plate structure is simplified for easy manufacture, then manufacturing cost is reduced, but thermal deformation control becomes difficult
Solution Approach 1:
Rather than redesigning the entire plate structure, the invention applies a localized concave feature only at the rear end where thermal effects are most problematic. This maintains the simplicity of the overall plate design for easy manufacture while adding precision control exactly where needed to manage thermal deformation during laser processing.
