Referring to fig. 2, the invention also provides a working method of the laser cleaning quenching device, which comprises the following steps:

104. in the second walking process of the wall-climbing robot 20, the control system 10 controls the optical lens of the cleaning and quenching functional head 40 to swing and controls the laser to emit light to quench the cleaned structural member.
When the structural member needs to be cleaned, the control system 10 controls the wall-climbing robot 20 to walk according to a first preset path, and in the first walking process of the wall-climbing robot 20, the control system 10 simultaneously controls the optical lens of the cleaning and quenching functional head 40 to swing so as to adjust the focal position of the cleaning and quenching functional head 40 and control the laser to emit light to perform laser cleaning on the structure. After the cleaning is finished, if the structural part needs to be quenched continuously, the control system 10 controls the wall-climbing robot 20 to walk according to a preset second path, and in the second walking process of the wall-climbing robot 20, the control system 10 simultaneously controls the optical lens of the cleaning and quenching functional head 40 to swing so as to adjust the focal position of the cleaning and quenching functional head 40 and control the laser to emit light to perform laser quenching on the structure.
If the structure is not required to be cleaned during quenching, the control system 10 can directly control the laser to emit light to perform laser quenching on the structure in the first walking process of the wall-climbing robot 20.
Further, in step 102, the control system 10 controls the optical lens of the cleaning and quenching functional head 40 to swing and controls the laser to emit light to clean the structural member specifically may be:
the control system 10 controls the optical lens oscillation of the cleaning and quenching functional head 40 and controls the second laser 32 to emit low power laser light to clean the structure.
When the surface of the structure has no pollutants difficult to clean, only the hardness and the strength of the material need to be increased. The second laser 32 is a pulse laser, the pulse laser is a low-power laser, and the power P2 is less than or equal to 200W. Therefore, the surface of the structural member can be laser cleaned only by controlling the second laser 32 (pulse laser) to emit laser. By carrying out laser cleaning on pollutants on the surface of the structural member before quenching, the absorption of laser during quenching can be improved, and the surface quenching quality and efficiency of the structural member are improved.
Or, in step 102, the step of controlling the optical lens of the cleaning and quenching functional head 40 to swing and controlling the laser to emit light to clean the structural member by the control system 10 may specifically be:
the control system 10 controls the optical lens of the cleaning and quenching functional head 40 to swing and controls the first laser 31 to emit high-power laser to perform rough cleaning on the structural part;
the control system 10 controls the optical lens of the cleaning and quenching functional head 40 to swing and controls the second laser 32 to emit low power laser light to finish clean the structural part.
When paint or other pollutants difficult to clean exist on the surface of the structural part, the low-power laser cleaning efficiency is too low, and high-power laser cleaning equipment must be adopted for cleaning, but the high-power pulse laser is limited by technical reasons, the power cannot be greatly improved, the equipment price is too high, and the application of the high-power pulse laser is greatly restricted; meanwhile, the high-power cleaning process is easy to oxidize to cause the substrate to turn blue and yellow, so that the effect of the substrate after cleaning is poor.
Therefore, in the technical scheme, the first laser 31 (high-power semiconductor laser) and the second laser 32 (low-power pulse laser) are used for cleaning paint and other objects difficult to clean, so that the cleaning efficiency and effect can be improved, and the cost of equipment is reduced. Firstly, roughly cleaning the surface of a structural part by a first laser 31 (a high-power semiconductor laser), wherein the laser energy of the first laser 31 is high, and although pollutants such as paint are cleaned, the surface of the structural part after cleaning is subjected to secondary oxidation; therefore, the structure is subjected to a fine cleaning by the low-power laser of the second laser 32, and the secondary oxidation is removed to complete the cleaning work.
Further, in step 104, the control system 10 controls the optical lens of the cleaning and quenching functional head 40 to swing and controls the laser to emit light to quench the cleaned structural component specifically:
the control system 10 controls the optical lens of the cleaning and quenching functional head 40 to swing and controls the first laser 31 to emit high-power laser to quench the cleaned structural component.
The first laser 31 is a high-power semiconductor laser, the power P1 is larger than or equal to 3000W, and the control system 10 controls the first laser 31 to emit high-power laser to quench the cleaned structural member, so as to increase the strength and hardness of the structural member.
The above description is provided by way of example for the operation method of the laser cleaning and quenching apparatus, and it should be noted that the operation method of the laser cleaning and quenching apparatus is not limited thereto, and the operation method is not limited thereto. For example, when the cleaning and quenching functional head 40 is split into a first functional head and a second functional head, the control system 10 can also emit light from the first laser 31 and the second laser 32 respectively, so as to clean and quench the structure at the same time, thereby greatly improving the working efficiency of the laser cleaning and quenching device.
In view of the above, it is intended that the present invention not be limited to the laser cleaning and quenching apparatus and the cutting method, but that the present invention is capable of being practiced and carried out in various forms and embodiments.
