1Productivity
If transportation plates are used to convey dross under laser beam irradiation, then dross transportation is enabled, but thermal deformation and deflection of the plates occur due to excessive heat
Solution Approach 1:
A cooling plate is introduced as an intermediary component between the laser beam irradiation source and the transportation plate. The cooling plate absorbs excess heat from the laser irradiation, preventing it from transferring to the transportation plate, thereby eliminating thermal deformation while maintaining dross transportation functionality
Solution Approach 2:
The patent replaces the conventional direct mechanical contact system with a cooling intermediary system that uses thermal management principles. Instead of relying solely on the transportation plate's structural integrity to withstand heat, a cooling mechanism is introduced to actively manage thermal energy, substituting passive mechanical resistance with active thermal control
2Temperature
If cooling measures are implemented to prevent thermal deformation, then temperature rise is restrained, but device complexity increases
Solution Approach 1:
The cooling function is merged with the existing conveyor structure by integrating the cooling plate into the transportation mechanism. The cooling plate serves dual purposes: it acts as both a cooling element to prevent thermal deformation and as part of the transportation system, thereby achieving temperature control without proportionally increasing device complexity
Solution Approach 2:
The cooling plate is designed to perform multiple functions simultaneously: it cools the transportation plate to prevent thermal deformation, supports the transportation of dross, and maintains structural integrity of the conveyor system. This multi-functionality reduces the need for separate cooling devices, thereby limiting the increase in device complexity

AI summary
A dross transportation conveyor includes a group of transportation plates, a first temperature rise restraining surface, and a second temperature rise restraining surface. The transportation plates include a first transportation plate and a second transportation plate. The first transportation plate extends in a first direction. The second transportation plate is disposed to be adjacent to the first transportation plate and extends in the first direction. The transportation plates transport dross generated by irradiation of a laser beam on a workpiece. The first temperature rise restraining surface covers at least a part of the first transportation plate to restrain a temperature rise of the first transportation plate due to energy of the laser beam. The second temperature rise restraining surface covers at least a part of the second transportation plate to restrain a temperature rise of the second transportation plate due to the energy of the laser beam.
