[0050] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal, a device terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 1 FIG. 1 is a schematic diagram of the hardware environment of a method for controlling a composite light spot according to an embodiment of the present application. Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown) a processor 102 (the processor 102 may include but is not limited to a microprocessor MCU or a programmable logic device FPGA and other processing devices) and a memory 104 for storing data. In an exemplary embodiment, the computer terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It will be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. For example, the computer terminal may also include Figure 1 More or fewer components than shown, or with Figure 1 Equivalent functions or comparisons shown Figure 1 Shown are different configurations with more functionality.

[0051] The memory 104 can be used to store computer programs, such as software programs and modules of application software, such as the computer program corresponding to the control method of the composite light spot in the embodiment of the present invention. The processor 102 executes the computer program stored in the memory 104 to perform various functional applications and data processing, thereby implementing the above-mentioned method.

[0052] The transmission device 106 is used to receive or transmit data via a network.

In another embodiment, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0053] In this embodiment, a control method for a composite light spot is provided, which is applied to the above-mentioned device terminal. Figure 2 is a flow chart of a method for controlling a composite light spot according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0054] Step S202, extracting a target cleaning feature corresponding to a cleaning layer on the surface of the material to be cleaned, wherein the target cleaning feature is used to indicate a material property of the cleaning layer, and the cleaning layer is a surface material to be removed on the surface of the material to be cleaned;

[0055] Step S204, generating preheating parameters and cleaning parameters according to the target cleaning characteristics, wherein the preheating parameters are used to indicate the properties of the light beam that can preheat the cleaning layer, and the cleaning parameters are used to indicate the properties of the light beam that can clean the cleaning layer;

[0056] Step S206, generating a composite light spot that meets both the preheating parameters and the cleaning parameters, wherein the composite light spot is divided into a first area and a second area, the first area outputs a continuous laser that meets the preheating parameters, and the second area outputs a pulsed laser that meets the cleaning parameters, and the composite light spot is used to remove the cleaning layer.

[0057] Through the above steps, the target cleaning features corresponding to the cleaning layer on the surface of the material to be cleaned are first extracted, and preheating parameters and cleaning parameters are generated according to the material properties indicated by the target cleaning features. Finally, a composite light spot that meets both the preheating parameters and the cleaning parameters is generated. The first area of ​​the composite light spot outputs a continuous laser that meets the preheating parameters to preheat the cleaning layer, and the second area of ​​the composite light spot outputs a pulsed laser that meets the cleaning parameters to clean the preheated cleaning layer. Since the cleaning layer has undergone preheating treatment, the laser power corresponding to the pulsed laser can be reduced when the pulsed laser is subsequently used for cleaning. In other words, the power consumption of the pulsed laser during the cleaning process is reduced. The above technical solution solves the problem of high power consumption of laser cleaning in related technologies and achieves the technical effect of reducing the power consumption of laser cleaning.

[0058] It should be noted that continuous laser allows long-term laser output and has good thermal effect, which is suitable for occasions such as cutting and welding. Pulsed laser outputs laser in a pulsed working mode and has the characteristic of large output power. The large output power can instantly vaporize the processed surface and is suitable for laser deep engraving, marking and other occasions. Using continuous laser alone may result in low cleaning efficiency. Using pulsed laser alone, although the cleaning effect is good, due to the large output power of pulsed laser, the cleaning power consumption may be too high when facing thicker cleaning layers, resulting in increased cleaning costs. At present, the best solution for laser cleaning applications is to use continuous laser and pulsed laser to work together to clean cleaning layers such as rust, paint, and dirt. First, the good thermal effect of continuous laser is used to preheat the cleaning layer, and then the pulsed laser is used to clean the preheated cleaning layer. Compared with the cleaning layer that has not been preheated, to achieve the same cleaning effect, the power required by the pulsed laser will be greatly reduced. The collaborative working method can achieve the effect of reducing the power consumption of laser cleaning.

[0059] In the technical solution provided in the above step S202, the material to be cleaned may include, but is not limited to, any material that requires cleaning, and the cleaning layer may include, but is not limited to, any surface layer of rust, paint, dirt, etc. attached to the surface of the material to be cleaned that is to be removed by laser cleaning. For example, a ship is a material to be cleaned, and the rust attached to the surface of the ship is the cleaning layer.

[0060] Optionally, in this embodiment, the target cleaning feature can be, but is not limited to, any material property of the cleaning layer. For example, it can be, but is not limited to, a thickness feature and a material feature. For the same thickness feature, but with different material features, for example, paint and rust of the same thickness, the corresponding cleaning conditions are different due to the different materials; for the same material, but with different thicknesses, the corresponding cleaning conditions may also be different.

[0061] In an exemplary embodiment, after generating a composite light spot that meets both the preheating parameters and the cleaning parameters, the following methods may also be used, but are not limited to: obtaining temperature data collected by temperature sensors deployed at one or more temperature detection points, and obtaining light output data collected by photoelectric sensors deployed at one or more light output detection points; when the temperature data does not fall within a safe temperature range, and / or the light output data does not fall within a safe light output range, a light output abnormality is prompted.

[0062] Optionally, in this embodiment, the temperature sensor is used to collect temperature data at the deployment location, and the photoelectric sensor is used to collect light output data at the deployment location. The sensor may indicate light output abnormality in, but is not limited to, the following three situations:

[0063] In case 1, the temperature data collected by the temperature sensors deployed at one or more temperature detection points (the connection between the beam combiner and the film stripper) show that the temperature at the temperature detection point does not fall within the safe temperature range, indicating abnormal light output;

[0064] Case 2: When the light detection point (the fusion point of the beam combiner) is prohibited from emitting light, when the laser is turned on, if the light output data of the photoelectric sensor indicates that there is light leakage at the light detection point, it will prompt a light output abnormality;

[0065] Case three: when the light emission detection point (the fusion point of the beam combiner) is of the type that allows light emission, when the laser is turned on, and the light emission data of the photoelectric sensor indicates that there is no light emission at the light emission detection point, a light emission abnormality is prompted.

[0066] In the technical solution provided in the above step S204, the best solution for laser cleaning applications at present is to use continuous laser and pulsed laser to work together to clean the cleaning layers such as rust, paint, dirt, etc. First, the cleaning layer is preheated using the good thermal effect of the continuous laser, and then the preheated cleaning layer is cleaned using the pulsed laser. Compared with the cleaning layer that has not been preheated, the power required by the pulsed laser will be greatly reduced to achieve the same cleaning effect. The collaborative working method can achieve the effect of reducing the power consumption of laser cleaning.

[0067] Optionally, in this embodiment, the preheating parameters are used to indicate the beam properties of the continuous laser, thereby generating a continuous laser that can preheat the cleaning layer. The preheating parameters can be used to indicate the power of the continuous laser, the preheating time of the continuous laser, the wavelength of the continuous laser and other beam properties.

[0068] Optionally, in this embodiment, the cleaning parameters are used to indicate the beam properties of the pulsed laser, thereby generating a pulsed laser that can clean the cleaning layer. The cleaning parameters can be used to indicate the power of the pulsed laser, the light output frequency of the pulsed laser, the cleaning time of the pulsed laser and other beam properties.

[0069] In an exemplary embodiment, preheating parameters and cleaning parameters can be generated based on the target cleaning characteristics in the following manner, but are not limited to: generating a preheating temperature that meets the material type and material thickness included in the target cleaning characteristics as the preheating parameter; predicting the material hardness of the cleaning layer when the preheating temperature is reached; and generating a unit energy density that meets the material type, material thickness, and material hardness as the cleaning parameter.

[0070] Optionally, in this embodiment, a cleaning layer having a material type T and a material thickness H is preheated by continuous laser so that the cleaning layer reaches the preheating temperature. At this time, the internal structural organization of the cleaning layer changes, and the material hardness exhibited by the cleaning layer will also change to hardness A. Based on the above parameters, the unit energy density of material type T with a hardness parameter of hardness A and a thickness parameter of material thickness H is determined.

[0071] In the technical solution provided in the above step S206, the composite light spot is divided into a first area and a second area, wherein the first area and the second area can be, but are not limited to, annularly distributed, or point-distributed, and can be uniformly distributed or non-uniformly distributed. There is no limitation on the distribution mode of the first area and the second area, and the specific mode can be designed according to actual needs. The distribution mode can be achieved through array arrangement. Based on the above principle, the composite light spot can be divided not only into the first area and the second area, but also into more than three areas, with the purpose of independent light output control of each area.

[0072] In an exemplary embodiment, a composite light spot that meets both the preheating parameters and the cleaning parameters can be generated in the following manner, but is not limited to: generating a first control instruction carrying the preheating parameters, and generating a second control instruction carrying the cleaning parameters, wherein the first control instruction is used to instruct the emission of a laser beam that meets the preheating parameters, and the second control instruction is used to instruct the emission of a laser beam that meets the cleaning parameters; sending the first control instruction to a continuous laser emission module, and sending the second control instruction to a pulsed laser emission module; outputting a combined laser beam of the continuous laser and the pulsed laser as the composite light spot, wherein the continuous laser is output by the continuous laser emission module, and the pulsed laser is output by the pulsed laser emission module.

[0073] Optionally, in this embodiment, the composite light spot is divided into a first area and a second area, wherein the first area and the second area are controlled by independent light output modules respectively. Figure 3 is a schematic diagram of a control device for a composite light spot according to an embodiment of the present application. Figure 3As shown, the control device for the composite light spot includes: a control module and two sub-modules (sub-module 1 and sub-module 2), wherein the control module is composed of a CPLD (Complex Programmable Logic Device, digital integrated circuit) and a single-chip microcomputer, and the CPLD and the single-chip microcomputer are connected via an SPI (Serial Peripheral Interface, serial peripheral interface), and the control module controls the connected sub-module 1 and sub-module 2 separately, wherein a continuous control system is deployed in sub-module 1; and a pulse control system is deployed in sub-module 2. When the control module sends the first control instruction to the continuous laser emission module (sub-module 1), the continuous control system controls the lower-layer connected electrical modules (electrical modules 1 to electrical modules n) to drive the corresponding optical modules (optical modules 1 to optical modules n) to emit laser beams that meet the preheating parameters according to the preheating parameters indicated by the first control instruction, and the pulse control system controls the lower-layer connected electrical modules (electrical modules 1 to electrical modules n) to drive the corresponding optical modules (optical modules 1 to optical modules n) to emit laser beams that meet the cleaning parameters according to the cleaning parameters indicated by the second control instruction. Then, a beam combiner outputs the combined laser light of the continuous laser and the pulse laser as the composite light spot.

[0074] Optionally, in this embodiment, in order to ensure the flexibility of device control, such as Figure 3 As shown, the control module has a channel switching function. All control signals can be selected through a two-choice analog selector to achieve signal source selection. The signal can be given by the added HMI (Human Machine Interface) or automatically given directly by the upstream device through signal acquisition. Figure 4 is a schematic diagram of channel switching according to an embodiment of the present application, such as Figure 4 As shown, when the HMI receives an external control signal, the external control signal is first digitally isolated. When the analog selector indicates that the signal source can be given by the HMI, the external control signal is used as the laser control signal. When the analog selector indicates that the signal source can be automatically and directly given by the upstream device, the internal control signal is used as the laser control signal.

[0075] Optionally, in this embodiment, the control device of the composite light spot is a control board (i.e., the control module mentioned above). This control board has hard lines and communication interfaces for two sets of lasers, and uses an RS232 communication interface and an Internet port to receive control instructions. The light output of the two lasers (i.e., the above-mentioned sub-module 1 and sub-module 2) is controlled by the control signal of the hard line to ensure the response speed of the whole machine. At the same time, the communication interface of the two lasers is added, and the host computer functions of the two lasers can be integrated, which is beneficial to the production and debugging of the whole machine, without having to debug and set parameters for the two laser modules separately. In addition, the control board can also receive analog light power to further control the analog light output.

[0076] In an exemplary embodiment, the combined laser beam of the continuous laser and the pulsed laser can be output as the composite light spot in the following manner, but is not limited to: outputting the continuous laser from the central core cluster of an output optical fiber, wherein the output optical fiber includes the central core cluster and a cladding core cluster; and outputting the pulsed laser from the cladding core cluster.

[0077] Optionally, in this embodiment, Figure 5 is a schematic diagram of a composite light spot according to an embodiment of the present application, such as Figure 5 As shown, the output optical fiber is formed by arranging and bundling a central core cluster and a cladding core cluster. The cladding core cluster outputs continuous laser to preheat the cleaning layer, and the central core cluster outputs pulsed laser to clean the preheated cleaning layer.

[0078] In an exemplary embodiment, after the first control instruction is sent to the continuous laser emission module and the second control instruction is sent to the pulse laser emission module, the target light emitting area and the target light emitting power can also be determined according to the target parameters carried by the target control instruction received by the target laser emission module in the following manner, but is not limited to, wherein the laser emission module includes the continuous laser emission module and the pulse laser emission module, the target control instruction includes the first control instruction and the second control instruction, and the target parameters include the preheating parameters and the cleaning parameters; one or more electrical modules matching the target light emitting area are determined from the electrical module array deployed in the target laser emission module; and the one or more electrical modules are controlled to drive the corresponding optical modules to output laser light that meets the target light emitting power to the connected fiber core.

[0079] Optionally, in this embodiment, if Figure 3As shown, first, submodule 1 and submodule 2 include a control system, an electrical module, and an optical module. The pulse control system and the continuous control system are connected to the control module through corresponding hardware and software control interfaces. The control module can control or read the status of the continuous laser and the pulsed laser. Submodule 1 and submodule 2 control their respective electrical modules to drive the corresponding optical modules according to the received control instructions. It should be noted that the number of optical modules may not be consistent with the number of electrical modules. Depending on the optical modules, one electrical module can drive multiple optical modules. This design method allows for the timely addition and replacement of modules in subsequent power upgrades and after-sales maintenance, achieving the purpose of rapid upgrades and maintenance.

[0080] In an exemplary embodiment, the one or more electrical modules can be controlled to drive the corresponding optical modules to output a laser that meets the target optical output power to the connected fiber core in the following manner, but is not limited to: detecting the scattering power of the scattered laser generated by the initial laser output from the output optical fiber that outputs the composite light spot, wherein the power ratio between the scattered laser and the initial laser is a target ratio; determining the initial optical output power corresponding to the initial laser based on the scattering power and the target ratio; and adjusting the target parameters until the initial optical output power is corrected to the target optical output power.

[0081] Optionally, in this embodiment, for this type of composite laser, the accuracy of power control is particularly important. Under the premise of being able to accurately obtain the actual optical power, by introducing closed-loop control, Figure 6 is a schematic diagram of a power closed-loop control according to an embodiment of the present application, such as Figure 6 As shown, the actual output optical power is used as negative feedback to compare with the set output optical power. The difference between the two is input to the corrector. After correction by the corrector, a current value is generated and sent to sub-module 1 and sub-module 2. Sub-module 1 and sub-module 2 respectively drive the corresponding electrical modules to adjust the pump current, thereby achieving the purpose of changing the output optical power. After closed-loop control, the deviation between the set output optical power value and the actual output optical power value approaches zero. However, since the power of the laser light emitted by the laser is generally high, direct measurement may damage the measuring instrument. Instead, the power corresponding to the scattered light of the laser can be detected. Based on the scattered light power, the actual output optical power is calculated by the power ratio of the actual output light to the scattered light, as well as the nonlinear correction and the difference.

[0082] Through the above implementation method, the whole machine includes a main control board and a laser module. The two laser modules (sub-module 1 and sub-module 2) are controlled by a main control board (control module). The main control board and the laser module are in a master-slave topology. At the same time, the main control board controls the two laser modules through hard-wired signals. By utilizing the protection function of the laser module itself, the fault status of the laser module can be read through the communication interface to achieve the fusion of the status information of the whole machine. Finally, a beam combiner and a special optical fiber are used to combine the optical fibers of the two laser modules, and a temperature sensor and a photoelectric sensor are added to monitor the abnormal light output status.
