[0044] During laser processing such as laser engraving and laser cutting, dust is inevitably generated. If the dust is adsorbed on the laser mirror, it will interfere with the laser light and affect the processing effect.

[0045] In the related art, an air pump is set to blow away dust during laser processing to slow down or prevent dust from adsorbing on the laser mirror. However, during laser processing, the amount of dust generated during processing varies due to the different materials being processed and the changes in processing parameters such as laser processing power and processing speed. Currently, the air pump can only be adjusted by manually and mechanically selecting the working gear of the air pump to adjust the air output of the air pump so that the air pump can more effectively purify the generated smoke and gas, which is inconvenient to operate.

[0046] In order to solve the above problems, the present invention proposes a control method of a laser processing device 1, which is applied in a laser processing system 100. Figure 1The laser processing system 100 includes a laser processing device 1 and an air pump 2. The laser processing device 1 can be, but is not limited to, a laser engraving machine, a laser cutting machine, a laser marking machine, and a laser welding machine. The laser processing device 1 is provided with an air outlet passage connected to the air pump 2. The air pump 2 is in communication connection with the laser processing system 100. The air pump 2 can blow air during the laser processing process to slow down or avoid the adsorption of dust on the laser mirror, avoid affecting the laser emission and the laser processing effect, and can also reduce or eliminate the effect of smoke during the processing. The laser processing device 1 can execute the control method proposed in the present invention, and output the air pump adjustment instruction to the air pump 2, so that the air pump 2 adjusts the air outlet according to the air pump adjustment instruction during the laser processing device 1 performs the processing task.

[0047] Specifically, the laser processing equipment 1 can be, but is not limited to, a laser engraving machine, a laser cutting machine, a laser marking machine, and a laser welding machine; the laser processing equipment 1 performs processing tasks according to processing task information, and the processing task information may include processing materials, processing patterns, processing start time, processing end time, processing power, and processing speed, etc.; wherein, the processing pattern may only include processing contours, or may include information such as engraving depth and cutting material thickness, and in the same laser processing task, processing requirements for laser cutting and laser engraving may be included at the same time. The processing power and processing speed may be specific values ​​or value ranges, and may be generated according to processing materials and processing patterns, or may be set and adjusted according to user needs.

[0048] The air pump configuration information may include the corresponding relationship between at least one parameter such as the working power of the air pump 2, the stroke of the piston of the air pump 2 or the speed and flow rate of the crankshaft and the air output of the air pump, and may also include the mapping relationship between the working gear of the air pump 2 and the air output, that is, the air output of the air pump corresponding to each working gear is pre-set. The air pump configuration information can be directly established in the laser processing device 1, or sent to the laser processing device 1 by the host computer 3 or downloaded from the server 4 by the laser processing device 1.

[0049] The air pump 2 has the functions of suction and exhaust, and the exhaust port of the air pump 2 is connected to the air outlet passage provided in the laser processing equipment 1; the air outlet end of the air outlet passage is provided near the light outlet head so as to blow toward the area toward which the light outlet head is directed; in some embodiments, the air outlet passage can also be connected to the light outlet passage so that the air flow is blown out directly from the light outlet. The air pump 2 is connected to the laser processing equipment 1 by communication, which can be a wired connection or a wireless connection, such as using a Bluetooth connection or connecting the air pump 2 and the laser processing equipment 1 to the same local area network; thereby, signal transmission can be performed between the air pump 2 and the laser processing equipment 1, so that the laser processing equipment 1 can send control instructions to the air pump 2.

[0050] Optionally, the laser processing system 100 includes a host computer 3, which can send processing task information and air pump configuration information to the laser processing equipment 1. The host computer 3 can be a terminal device such as a mobile phone, a computer or a tablet. The host computer 3 is provided with a host computer software, which can be used to receive or establish laser processing tasks and air pump configuration information. In some embodiments, the host computer 3 can also be used to monitor the laser processing process and the operating status of the air pump 2, etc., which is not limited here. Optionally, the host computer 3 and the laser processing equipment 1 can be connected by wired communication through a signal line, or wireless communication can be achieved by using Bluetooth or connecting to the same local area network; it is only necessary to enable the host computer 3 to send the laser processing tasks and air pump configuration information to the laser processing equipment 1; in some embodiments, the laser processing equipment 1 can also send the actual processing information to the host computer 3 for feedback and storage.

[0051] The processing task information and the air pump configuration information in the host computer 3 can be directly set by the user in the host computer 3 or automatically generated by software; the processing task information and the air pump configuration information can also be modified in the host computer 3. In some embodiments, the laser processing system 100 also includes a server 4, which can be used to store data, such as equipment parameters, processing parameters of the laser processing equipment 1, and configuration parameters of the air pump 2. The host computer 3 can obtain the required data information from the server 4, or upload the data information to the server 4 for storage.

[0052] Please refer to Figure 2 In some embodiments of the present application, a control method of a laser processing device includes:

[0053] Step S10, obtaining processing task information and air pump configuration information of the air pump.

[0054] In an embodiment, the laser processing task information and the air pump configuration information can be directly established in the laser processing equipment, or the processing task information and the air pump configuration information can be sent to the laser processing equipment by the host computer, or the laser processing equipment can download the processing task information and the air pump configuration information from the server.

[0055] Step S20, starting the laser processing program according to the processing task information and simultaneously starting the air pump.

[0056] The laser processing equipment can start the laser processing program for processing according to the laser processing task information; it can start immediately when receiving the laser processing task, or start the processing at a preset time according to the set processing start time. When the laser processing equipment starts to execute the processing task, it synchronously controls the air pump to start to perform the blowing operation, without the need to manually control the air pump to start separately, reducing manual participation and improving the degree of automation; and ensure that the laser processing system will blow air synchronously when the laser processing task starts, avoiding the delayed start of the air pump and causing the dust generated during the initial processing to adhere to the laser mirror and affect the processing effect. In step S20, the laser processing equipment can detect whether the air pump is online. If the air pump is not online, it can issue a prompt to remind the user to connect the air pump to the Internet to avoid the laser processing equipment being unable to control the air pump to start synchronously.

[0057] Step S30, outputting an air pump adjustment instruction to the air pump according to the processing task information and the air pump configuration information, so as to adjust the air output of the air pump during the laser processing.

[0058] It is understandable that for different processing powers, processing speeds, processing materials, different processing operations (such as engraving and cutting at different positions respectively), and the differences in engraving depth, cutting thickness or incision width at different positions of the desired product pattern or shape, the amount of dust generated during the processing will be different; therefore, it is necessary to adjust the air pump output. If the air pump output is small when more dust is generated during the laser processing, it is easy to have the problem of not being able to blow away the dust well; if the air pump always maintains a high air output, there will be a problem of energy waste when less dust is generated, resulting in higher energy consumption. For example, when the processing power is greater during laser processing, the more light is emitted during processing, the stronger the laser energy, and the more dust is generated; and when the processing speed is slower during laser processing, that is, the longer the stay time at the processing position, the more laser is emitted at the processing position, and the more dust is generated at this time.

[0059] In the embodiment of the present application, the laser processing equipment can adjust the air pump output according to the processing task information and the air pump configuration information, so that when different dust amounts are generated, the air pump can blow out appropriate airflow to blow away the dust. For example, when the processing power is greater during laser processing, the more smoke and dust are generated. At this time, the air pump output needs to be increased to achieve a better dust removal effect; on the contrary, when the processing power of the laser processing becomes smaller, the smoke and dust generated at this time are less, and the air pump output can be reduced to reduce the energy consumption of the air pump. Alternatively, when the processing speed is slower during laser processing, the more smoke and dust are generated, and the air pump output needs to be increased to achieve a better dust removal effect; on the contrary, when the processing speed of the laser processing increases, the smoke and dust generated at this time are less, and the air pump output can be reduced to reduce the energy consumption of the air pump. The laser processing system can automatically adjust the air pump output according to the laser processing task to maintain a good dust removal effect and avoid excessive energy consumption during the processing; and there is no need to manually control and adjust the air pump, which improves the control convenience and realizes automation.

[0060] Optionally, the air output of the air pump can be controlled by adjusting the working power of the air pump, the stroke of the air pump piston, the speed of the crankshaft and other parameters according to the type of the air pump. In some embodiments, the air pump is preset with working gears and the air output of each working gear is set. According to the mapping relationship between the working gear and the air output of the air pump, the air output of the air pump can be adjusted by selecting and switching the working gear of the air pump, and the operation control is more convenient.

[0061] Therefore, it can be understood that in the technical solution of the present application, the air pump can automatically adjust the air output of the air pump according to the laser processing task to ensure that when processing different processing materials, processing patterns or when using different laser processing parameters, the air pump can blow out sufficient airflow to blow away dust, slow down or avoid the adsorption of dust on the laser mirror, and there is no need for manual control and adjustment of the air pump, thereby improving the control convenience of the air pump and realizing automation; and avoiding the air pump always maintaining a high air output during the laser processing process, resulting in excessive energy consumption and waste of resources.

[0062] In one embodiment of the present invention, the control method of the laser processing equipment further includes: turning off the air pump after the laser processing task is completed.

[0063] When the laser processing equipment completes processing of the workpiece, the air pump can be turned off. The system can automatically shut down the air pump when it detects that the laser processing equipment has completed processing. It can be shut down immediately or with a delay, which is conducive to improving the convenience of using the air pump, reducing manual participation, and improving the degree of automation.

[0064] In one embodiment of the present application, the processing task information includes processing pattern, processing material, processing speed and processing power.

[0065] The processing task information is used as reference information for guiding the laser processing equipment. The processing task information may include processing materials, processing patterns for engraving and cutting, processing start time, processing end time, processing power and processing speed, as well as the processing power and processing speed corresponding to each processing time, etc. Among them, the processing power and processing speed can be specific values ​​or value ranges, which can be generated based on the processing materials and processing patterns, or can be set and adjusted according to user needs.

[0066] In one embodiment of the present application, a mapping relationship between processing task information and gas output under different working modes can be preset, and the gas output can be adjusted according to the working mode, that is, the mapping relationship between processing task information and required gas output under different modes is different. In step S30, step S30 may include: obtaining the current working mode, obtaining the mapping relationship between processing task information and required gas output according to the current working mode, and then determining the required gas output based on the mapping relationship, generating a corresponding adjustment instruction based on the gas output, and then adjusting the gas output of the air pump during laser processing. For example, the working mode includes a cutting mode and an engraving mode, and the gas output requirements of the cutting mode and the engraving mode are different. In the cutting mode, there is a first mapping relationship between the processing task information and the gas output, and in the engraving mode, there is a second mapping relationship between the processing task information and the gas output. In step S30, the current working mode is obtained. If the current working mode is the cutting mode, the first required gas output corresponding to the processing task information is obtained according to the first mapping relationship, and an adjustment instruction of the air pump is generated based on the first required gas output. The adjustment instruction is sent to the air pump to control the air pump to output the first required gas output or a gas output greater than the required gas output; if the current working mode is the engraving mode, the second required gas output corresponding to the processing task information is obtained according to the second mapping relationship, and an adjustment instruction of the air pump is generated based on the second required gas output. The adjustment instruction is sent to the air pump to control the air pump to output the second required gas output or a gas output greater than the required gas output. Among them, in different working modes, the content of the air pump adjustment instruction output based on the processing task information and the air pump configuration information is roughly the same.

[0067] Please refer to Figure 3 In one embodiment of the present invention, the step S30 of outputting an air pump adjustment instruction to the air pump according to the processing task information and the air pump configuration information to adjust the air output of the air pump during the laser processing includes:

[0068] Step S31, calculating the required air output of the air pump according to at least one of the processing material, processing speed and processing power;

[0069] Step S32: outputting an air pump adjustment instruction to the air pump according to the required air output and the air pump configuration information to adjust the air output of the air pump.

[0070] In this embodiment, when the laser processing equipment adjusts the air pump output according to the processing task information, it can comprehensively calculate based on all the parameters in the processing task information to confirm the required air pump output; it can also confirm the required air output according to some of the processing parameters in the processing task information, for example, it can confirm the required air output according to one, two or more processing parameters. After determining the required air output, the laser processing equipment generates an air pump adjustment instruction according to the air pump configuration information and the required air output and outputs it to the air pump, adjusting the air pump output of the air pump to the required air output. For example, in the following embodiment, the air pump output can be adjusted according to only one of the processing parameters such as processing power, processing speed and processing material, or at least two parameters can be obtained and the air pump output can be adjusted according to the mapping relationship between the obtained parameters and the air pump output. The specific implementation method refers to the following embodiment and will not be repeated here.

[0071] Optionally, the air pump output can be adjusted in such a way that the air pump has at least two working gears, and the air pump output is different when the air pump runs in different working gears. The target working gear of the air pump is determined according to the determined required air output, and the air pump is operated in the target working gear. Then the air pump adjustment instruction may include the working gear of the air pump. In addition, the air pump may also be adjusted steplessly, for example, by using a pulse width modulation method (PWM method), changing the power supply frequency and voltage of the air pump motor to adjust the air pump output; so that the air pump can output any required air output within a certain air output range, so that the air pump output is more accurately adapted to the amount of dust generated, and the air pump adjustment instruction may include the working voltage, current, frequency, duty cycle, etc. of the air pump.

[0072] Please refer to Figure 4 In one embodiment of the present application, the step S31 of calculating the required air output of the air pump according to at least one of the processing material, the processing speed and the processing power includes:

[0073] Step S311, obtaining the current processing power, and determining the required gas output according to the mapping relationship between the current processing power and the gas output of the air pump.

[0074] In this embodiment, the air pump gas output is adjusted according to the processing power of the laser processing equipment. Optionally, the required gas output can be obtained according to the specific numerical value of the processing power; or the required gas output can be obtained according to the power interval in which the current processing power is located and the mapping relationship between the power interval and the air pump gas output. For example, at least two power intervals can be pre-set, and the air pump gas output corresponding to each power interval can be set accordingly. The air pump has at least two working gears. It can be determined in real time or at a preset time interval to confirm which power interval the processing power of the laser processing equipment is located in. It can also be confirmed under the condition that the processing power changes, which power interval the changed processing power is located in, and then the required gas output is obtained according to the mapping relationship between the power interval and the air pump gas output. After determining the required gas output, the laser processing equipment generates an air pump adjustment instruction according to the air pump configuration information and the required gas output and outputs it to the air pump, and adjusts the air pump gas output of the air pump to the required gas output, so that the air pump gas output matches the current processing power, so as to ensure that the air pump generates an appropriate amount of airflow to play an effective air assisting role.

[0075] Please refer to Figure 4 In one embodiment of the present application, the step S31 of calculating the required air output of the air pump according to at least one of the processing material, the processing speed and the processing power includes:

[0076] Step S312, obtaining the current processing speed, and determining the required air output according to the mapping relationship between the current processing speed and the air output of the air pump.

[0077] In this embodiment, the air pump gas output is adjusted according to the processing speed of the laser processing equipment. Optionally, the required gas output can be converted according to the specific numerical value of the processing speed; or the required gas output can be obtained according to the speed interval in which the current processing speed is located, and according to the mapping relationship between the speed interval and the air pump gas output. For example, at least two speed intervals can be pre-set, and the air pump gas output corresponding to each speed interval can be set accordingly, so that the air pump has at least two working gears, and the speed interval in which the processing speed of the laser processing equipment is located can be determined in real time or confirmed at a preset time interval. It can also be confirmed in which speed interval the changed processing speed is located under the condition that the processing speed changes, and then the required gas output is obtained according to the mapping relationship between the speed interval and the air pump gas output. After determining the required gas output, the laser processing equipment generates an air pump adjustment instruction according to the air pump configuration information and the required gas output and outputs it to the air pump, and adjusts the air pump gas output of the air pump to the required gas output, so that the air pump gas output matches the current processing speed, so as to ensure that the air pump blows out an appropriate amount of airflow to play an effective dust removal role.

[0078] Please refer to Figure 4 In one embodiment of the present application, the step S31 of calculating the required air output of the air pump according to at least one of the processing material, the processing speed and the processing power includes:

[0079] Step S313, obtaining the current processing power and processing speed, and determining the required gas output according to the mapping relationship between the current processing power and processing speed and the gas output of the air pump.

[0080] In this embodiment, the processing power and processing speed of the laser processing equipment are comprehensively judged. In this embodiment, the required gas output of the air pump is comprehensively converted and matched according to the processing power and processing speed of the same processing stage. For example, the first gas output can be obtained according to the mapping relationship between the power interval where the processing power is located and the gas output of the air pump, and the second gas output can be obtained according to the mapping relationship between the speed interval where the processing speed is located in the same processing stage and the gas output of the air pump. The larger value of the first gas output and the second gas output is the required gas output, and the gas output of the air pump is adjusted to the required gas output. Alternatively, the average value of the first gas output and the second gas output is taken or the required gas output is obtained through other operation relationships. In some embodiments, an operation logic (such as a functional relationship) for obtaining the required gas output through the processing power and the processing speed can also be established, and the required gas output that matches the processing power and the processing speed is matched through the operation logic, which is not limited here. In the functional relationship, the processing power and the processing speed are independent variables, and the required gas output is the dependent variable. After the processing power and the processing speed are determined, the required gas output can be determined.

[0081] Please refer to Figure 4 In one embodiment of the present application, the step S31 of calculating the required air output of the air pump according to at least one of the processing material, the processing speed and the processing power includes:

[0082] Step S314, determining the required air output according to the mapping relationship between the processing material and the air output of the air pump.

[0083] It is understandable that different materials generate different amounts of dust during laser processing, and the adhesion strength of the generated dust is also different. In this embodiment, the laser processing equipment can determine the required air output according to the type of processing material to be processed, and then generate an air pump adjustment instruction according to the air pump configuration information and the required air output and output it to the air pump, adjust the air pump air output of the air pump to the required air output, and make the air pump blow out an appropriate amount of air flow for dust removal according to different processing materials.

[0084] Optionally, a mapping relationship between processing materials and air pump working gears can be established so that each working gear corresponds to at least one processing material; in addition, in some embodiments, the air pump gas output can be matched according to the properties of the material. For example, the hardness, melting point or other material property parameters of the material to be processed can be included in the processing task parameters sent by the host computer to the laser processing equipment, and the corresponding required gas output can be matched by one or at least two of the material property parameters.

[0085] Please refer to Figure 4 In one embodiment of the present application, the step S31 of calculating the required air output of the air pump according to at least one of the processing material, the processing speed and the processing power includes:

[0086] Step S315, obtaining at least one of the working parameters of the current processing power and the current processing speed, and determining the required gas output according to the mapping relationship between the gas output of the air pump, the processing material and the obtained working parameters.

[0087] In this embodiment, the judgment basis for adjusting the air pump gas output of the laser processing equipment includes at least the processing material and at least one of the working parameters of the processing power and the processing speed; that is, the required processing volume information is determined according to the processing material and at least one processing parameter. Optionally, the gas volume interval of the air pump gas output can be set according to the type of processing material or the nature of the processing material, so that when the laser processing equipment determines the processing material, the corresponding gas volume interval can be selected according to the type of processing material or the nature of the material, and then according to at least one working parameter of the processing power and the processing speed during the processing, the required gas output is determined in the selected gas volume interval, and the air pump is adjusted according to the air pump configuration information so that the air pump gas output is to the required gas output; the method of determining the required gas output according to at least one of the processing power and the processing speed during the processing can refer to the mapping method in the above embodiment, which will not be repeated here. By comprehensively considering the processing material and at least one working parameter of the processing power and the processing speed during the processing, the air pump gas output can be more matched with the actual working conditions, effectively improving the air pump air assist effect.

[0088] In one embodiment of the present application, for different processing materials, the mapping relationship between the processing parameters (at least one of the processing power and the processing speed) and the required air output is different. The processing material can be obtained first, and then the mapping relationship between the processing parameters and the required air output under the processing material can be obtained. Based on the mapping relationship and the processing parameters, the required air output corresponding to the air pump can be calculated.

[0089] Please refer to Figure 5 In one embodiment of the present application, the air pump configuration information at least includes the working gear of the air pump and the air output of each working gear. According to the required air output and the air pump configuration information, the step S32 of outputting the air pump adjustment instruction to the air pump to adjust the air output of the air pump includes:

[0090] Step S321, determining a target working gear of the air pump according to the required air output and the air pump configuration information;

[0091] Step S322, outputting the target working gear to the air pump to control the air pump to operate at the target working gear, and the air pump adjustment instruction includes the target working gear.

[0092] In this embodiment, the working gear of the air pump is preset and the air pump gas output of each working gear is set, that is, a mapping relationship between the working gear of the air pump and the air pump gas output is established. During the laser processing process, the air pump is operated according to the determined target working gear, so that the air pump gas output can be adjusted to the required gas output, without continuously adjusting the piston movement stroke, crankshaft speed, power supply frequency and power supply voltage of the air pump motor, etc., and the operation and control are relatively convenient.

[0093] In this embodiment, after the laser processing equipment confirms the required air output of the air pump based on at least one of the processing materials, working parameters, etc. in the processing task information, the target working gear corresponding to the required air output is determined according to the mapping relationship between the working gear of the air pump and the air output of the air pump, and an air pump adjustment instruction containing the target working gear information is sent to the air pump to make the air pump operate according to the target working gear, thereby adjusting the air output of the air pump to the required air output.

[0094] Optionally, the corresponding air pump configuration information can be set according to the air pump type without modification or replacement; the air pump configuration information can also be set according to the processing task information and the selected air pump type to meet the actual processing conditions.

[0095] Please refer to Figure 5 In one embodiment of the present application, the step S32 of adjusting the air output of the air pump according to the required air output and the air pump configuration information includes:

[0096] Step S323, calculating the control parameters of the air pump outputting the required air output according to the required air output and the air pump configuration information;

[0097] Step S324, outputting control parameters to the air pump so that the air pump operates according to the control parameters to provide the required air output, and the air pump adjustment instruction includes the control parameters.

[0098] In this embodiment, after confirming the required air output of the air pump according to at least one of the processing materials, working parameters, etc. in the processing task information, the laser processing equipment calculates the control parameters of the air pump when adjusting the air output of the air pump to the required air output according to the required air output and the air pump configuration information of the air pump. The control parameters may include parameter information such as the power supply voltage, power supply frequency, and duty cycle of the air pump motor; the laser processing equipment sends the air pump adjustment instruction containing the control parameters to the air pump, so that the air pump operates according to the control parameters, so that the air output of the air pump is adjusted to the required air output. With this setting, the air pump can output any required air output within a certain air output range, so that the air output of the air pump is more accurately adapted to the amount of dust generated.

[0099] Please refer to Figure 1The present application also proposes a laser processing system 100, which includes a laser processing device 1 and an air pump 2. The laser processing device 1 is provided with an air outlet passage connected to the air pump 2. The air pump 2 is communicatively connected to the laser processing system 100. The laser processing device 1 executes the control method of the laser processing device 1 in any of the aforementioned embodiments to output an air pump 2 adjustment instruction to the air pump 2, and the air pump 2 adjusts the air outlet volume according to the air pump 2 adjustment instruction.

[0100] The laser processing equipment 1 can be, but is not limited to, a laser engraving machine, a laser cutting machine, a laser marking machine, and a laser welding machine; the laser processing equipment 1 performs the processing task according to the processing task information, and the processing task information may include processing materials, processing patterns, processing start time, processing end time, processing power, and processing speed, etc.; wherein, the processing pattern may only include the processing outline, or may include information such as the engraving depth and the thickness of the cut material, and in the same laser processing task, the processing requirements of laser cutting and laser engraving may be included at the same time. The processing power and processing speed may be specific values ​​or value ranges, and may be generated according to the processing materials and processing patterns, or may be set and adjusted according to user needs. The processing task information may be set directly in the laser processing equipment 1, or may be sent to the laser processing equipment 1 by the host computer 3, or downloaded from the server 4 by the laser processing equipment 1.

[0101] The air pump configuration information may include the corresponding relationship between at least one parameter such as the working power of the air pump 2, the stroke of the piston of the air pump 2, or the speed of the crankshaft and the air output of the air pump, and may also include the mapping relationship between the working gear of the air pump 2 and the air output, that is, the air output of the air pump corresponding to each working gear is pre-set. The air pump configuration information can be directly established in the laser processing device 1, or sent to the laser processing device 1 by the host computer 3, or downloaded from the server 4 by the laser processing device 1.

[0102] The air pump 2 has the functions of suction and exhaust, and the exhaust port of the air pump 2 is connected to the air outlet passage provided in the laser processing equipment 1; the air outlet end of the air outlet passage is provided near the light outlet head so as to blow toward the area toward which the light outlet head is directed; in some embodiments, the air outlet passage can also be connected to the light outlet passage so that the air flow is blown out directly from the light outlet. The air pump 2 is connected to the laser processing equipment 1 by communication, which can be a wired connection or a wireless connection, such as using a Bluetooth connection or connecting the air pump 2 and the laser processing equipment 1 to the same local area network; thereby, signal transmission can be performed between the air pump 2 and the laser processing equipment 1, so that the laser processing equipment 1 can send control instructions to the air pump 2.

[0103] Since the laser processing system 100 of the present application can adopt the control methods of all the aforementioned embodiments, it at least has all the beneficial effects brought by all the aforementioned technical solutions, which are not described one by one here.

[0104] Please refer to Figure 1 In one embodiment, the laser processing system 100 also includes a host computer 3, which is communicatively connected to the laser processing equipment 1. The host computer 3 obtains the air pump configuration information and sends it to the laser processing equipment 1. The host computer 3 sends the laser processing task information to the laser processing equipment 1.

[0105] In this embodiment, the laser processing system 100 includes a host computer 3, which is used to send processing task information and air pump configuration information to the laser processing equipment 1. The host computer 3 can be a terminal device such as a mobile phone, a computer or a tablet. The host computer 3 is provided with a host computer software, which can be used to receive or establish laser processing tasks and air pump configuration information. In some embodiments, the host computer 3 can also be used to monitor the laser processing process and the operating status of the air pump 2, etc., which is not limited here. Optionally, the host computer 3 and the laser processing equipment 1 can be connected by wired communication through a signal line, or wireless communication can be achieved by using Bluetooth or connecting to the same local area network; it is only necessary to enable the host computer 3 to send the laser processing tasks and air pump configuration information to the laser processing equipment 1; in some embodiments, the laser processing equipment 1 can also send the actual processing information to the host computer 3 for feedback and storage.

[0106] The processing task information and air pump configuration information in the host computer 3 can be directly set by the user in the host computer 3 or automatically generated by software; the processing task information and air pump configuration information can also be modified in the host computer 3. Optionally, the host computer 3 can also obtain the air pump configuration information from the server 4, which is not limited here.

[0107] Please refer to Figure 1 In some embodiments, the laser processing system 100 further includes a server 4 , which is communicatively connected to the host computer 3 , and the host computer 3 sends identification information of the air pump 2 to the server 4 , and the server 4 sends air pump configuration information to the host computer 3 .

[0108] In this embodiment, the laser processing system 100 further includes a server 4, which can be used to store data, such as equipment parameters, processing parameters, and configuration parameters of the air pump 2 of the laser processing equipment 1. The host computer 3 can obtain the required data information from the server 4, or upload the data information to the server 4 for storage. When the host computer 3 needs to obtain the air pump configuration information, the identification information of the air pump 2 is uploaded to the server 4, and the server 4 can match the air pump configuration information corresponding to the identification information, and send the matched air pump configuration information to the host computer 3, so that the host computer 3 can send it to the laser processing equipment 1.

[0109] In some embodiments, after receiving the air pump configuration information, if the host computer 3 receives an instruction to modify the air pump configuration information, it obtains the modified air pump configuration information, sends the modified air pump configuration information to the laser processing equipment 1, and simultaneously uploads the configuration information to the server 4.

[0110] In this embodiment, if there is a difference between the preset configuration information in the server 4 and the air pump configuration information actually required, the preset air pump configuration information downloaded in the lower computer can be modified. For example, according to the different actual processing environments in which the laser processing system 100 is located, such as at least one of the factors such as the temperature, humidity, air pressure and ventilation degree of the processing environment, there may be differences in the degree of dust raising and the adhesion of dust to the laser mirror, and the processing environment may also affect the blowing effect of the air pump 2. Alternatively, if the current actual processing material or processing pattern does not have completely identical matching air pump configuration information in the server 4, the upper computer 3 can only synchronize relatively similar air pump configuration information or air pump configuration information templates. In this case, it is necessary to modify the preset air pump 2 parameters downloaded from the lower computer according to the actual processing environment and / or actual processing materials or patterns and other parameters to meet the current actual needs. For example, the number of gears and the air pump air output of each gear are set according to actual needs, and then the modified air pump configuration information is sent to the laser processing equipment 1 for synchronization, so that the laser processing equipment 1 can adjust the working gear of the air pump 2 according to the required air pump configuration information and processing task information.

[0111] Optionally, after the air pump configuration information is modified according to actual processing requirements to obtain air pump configuration information that meets the current processing conditions and processing requirements, the upper computer 3 uploads the air pump configuration information to the server 4 for storage to record the air pump configuration information of such processing conditions and processing requirements, so that the air pump configuration information can be called when the same processing conditions and processing requirements are encountered in the future, without the need for repeated modifications, thereby improving control convenience.
