Technical Field

[0001] The invention relates to the technical field of laser processing, and in particular to a control method and a laser processing system for a purifier. Background Art

[0002] During laser processing such as laser engraving and laser cutting, dust and smoke are inevitably generated. If the dust is deposited on the surface of the workpiece, it will easily affect the processing effect. Especially when engraving materials such as acrylic, it will also produce gases with strong odors, which will be harmful to the human body if inhaled for a long time.

[0003] In the related art, a purifier is used to filter heavy dust, smoke and gas during laser processing to achieve purification. However, during laser processing, due to changes in processing parameters such as laser processing power and processing speed, the amount of smoke and gas generated during processing also changes accordingly. The current purifier can only adjust the purification power of the purifier by manually selecting the working gear so that the purifier can fully and effectively purify the generated smoke and gas, which is inconvenient to operate. Summary of the invention

[0016] Or, according to the mapping relationship between the processing speed and the purification power, the expected purification power corresponding to the target processing speed is obtained;

[0017] Or, according to the mapping relationship among processing power, processing speed and purification power, the expected purification power corresponding to the target processing power and the target processing speed is obtained;

[0018] The steps of synchronously working according to the expected purification power include:

[0019] Adjust to the expected purification power and perform purification; or adjust the working gear to the gear where the expected purification power is located.

[0053] The present invention proposes a control method for a purifier 1, which is applied in a laser processing system 100. The laser processing system 100 includes a laser processing device 2 and a purifier 1. The purifier 1 is used to purify the smoke and gas generated during the laser processing. By executing the control method of the present application, the purifier 1 can be automatically controlled during the laser processing, and the control and use convenience of the purifier 1 can be improved while achieving better purification of the generated smoke and gas. Among them, the control method can be executed by the purifier 1.

[0054] Reference Figure 1 In the laser processing system 100, the laser processing device 2 is connected to the purifier 1 in communication. The laser processing device 2 may 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 2 performs processing tasks according to the set processing parameters. The processing parameters include processing paths, processing power, and processing speed, etc., and may be set accordingly according to the type of laser processing (such as engraving, cutting, marking, or welding), processing pattern, and processing material. The processing parameters may be generated directly in the laser processing device 2, or may be sent to the laser processing device 2 by the host computer 3, or downloaded from the server 4 by the laser processing device 2.

[0055] The purifier 1 is used to purify the smoke, dust, gas, etc. generated during the laser processing. It can be to only extract the smoke and gas, or to extract the smoke and gas and then filter, deodorize and purify them before discharging them. The purifier 1 can be used to perform the purification operation when the laser processing equipment 2 starts the laser processing, or the purifier 1 can be started before the laser processing, or the purifier 1 can be used to perform the purification operation after the laser processing equipment 2 starts the laser processing for a period of time. The purifier 1 is connected to the laser processing equipment 2 for communication, which can be a wired connection, such as a network cable, a USB data cable, or a wireless connection, such as a Bluetooth connection or connecting the purifier 1 and the laser processing equipment 2 to the same local area network, so that the purifier 1 and the laser processing equipment 2 can transmit signals, and the control signal can be sent to the purifier 1 by the laser processing equipment 2, and it can also be used to enable the purifier 1 to directly obtain the processing parameters or other information of the laser processing equipment 2.

[0056] Optionally, the laser processing system 100 also includes a host computer 3, which can be a terminal device such as a mobile phone, a computer or a tablet computer. The host computer 3 is provided with a host computer software, which can be used to receive and send control instructions. The host computer 3 can be connected to the laser processing system 100 for communication, and the host computer 3 can be used to generate a processing task for the laser processing equipment 2, which includes corresponding processing parameters, and can send the processing task to the laser processing equipment 2; in some embodiments, the host computer 3 can also be used to communicate with the purifier 1, and can send work information to the purifier 1, such as sending gear configuration information, delayed closing time information, etc. to the purifier 1 in the following embodiment, and can also send the processing parameters of the processing task performed by the laser processing equipment 2 to the purifier 1. The communication connection mode between the host computer 3 and the laser processing equipment 2 and the purifier 1 can be a wired connection or a wireless connection, such as using a Bluetooth connection or connecting the host computer 3 and the object of its communication connection to the same local area network, which is not specifically limited here.

[0057] Among them, the processing parameters and working information in the host computer 3 can be directly set by the user in the host computer 3 or automatically generated by software; in some embodiments, the laser processing system 100 also includes a server 4, which can be used to store data, such as equipment parameters of the laser processing equipment 2, processing tasks, and equipment parameters of the purifier 1, etc. The host computer 3 can obtain the required data information from the server 4, and can also upload the data information to the server 4 for storage.

[0058] Please refer to Figure 2 In some embodiments of the present application, the control method of the purifier includes the following steps:

[0059] Step S10, obtaining processing parameters in the processing task of the laser processing equipment.

[0060] Specifically, when it is necessary to start the purifier to start the purification operation, the user can turn on the purifier by himself, or the purifier can be linked with the laser processing equipment, and the purifier will automatically work when the laser processing equipment starts working. Optionally, the purifier can only have a power-on and power-off state, and the purification function is started when it is turned on; it can also be that the purifier has a standby state, so that the purifier can be in the power-on state but the purification function is not started; for example, in the following embodiments, the purifier can be turned on so that the purifier communicates with the laser processing equipment or the host computer to receive configuration information, and then performs the purification operation after receiving the purification function start instruction. The purifier can obtain the processing parameters of the laser processing equipment when performing the processing task. It can be that the laser processing equipment sends the running processing parameters to the purifier during the processing process, or the laser processing equipment or the host computer sends the corresponding processing parameters to the purifier when generating the processing task.

[0061] Step S20, determining the expected purification power of the laser processing equipment during the processing task according to the processing parameters.

[0062] Step S30, in response to the laser processing equipment executing the processing task, working synchronously according to the purification power.

[0063] During laser processing, such as laser engraving and laser cutting, the processing parameters of the laser processing equipment will be adjusted according to the size differences of the engraving depth, cutting thickness or incision width of the desired product pattern or shape in different materials and different positions, such as adjusting the processing power or processing speed during laser processing. The greater the processing power during laser processing, the more light is emitted during processing, the stronger the laser energy is, and the more smoke is generated; while the slower the processing speed 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 smoke is generated. If the purification power of the purifier is low when more smoke is generated during the laser processing, it is easy to have the problem of incomplete purification; if the purifier is always kept at a high purification power, there will be a problem of energy waste when less smoke is generated, resulting in higher energy consumption. In the embodiment of the present application, a mapping relationship between the processing parameters of the laser processing equipment and the purification power of the purifier can be established. For example, a mapping relationship between the processing power of the laser processing equipment and the purification power of the purifier is established, so that the processing power or the processing power interval corresponds to the purification power one by one; it is also possible to establish a mapping relationship between the processing speed of the laser processing equipment and the purification power of the purifier, so that the processing speed or the processing speed interval corresponds to the purification power one by one; it is also possible to comprehensively consider the processing power and the processing speed to correspond to different purification powers. Among them, according to the processing parameters of the laser processing equipment at various stages in the process of executing the processing task, the purifier can correspondingly match the expected purification power required to run at each stage. That is, the purifier can adjust the purification power in real time according to the real-time processing parameters of the laser processing equipment.

[0064] When the laser processing equipment performs a processing task, the purifier responds to the working state of the laser processing equipment to work synchronously with the laser processing equipment, and operates at the corresponding expected purification power at each stage of the laser processing equipment performing the processing task. For example, when the processing power is greater during laser processing, more smoke is generated. At this time, the purification power of the purifier needs to be increased; conversely, when the processing power of the laser processing becomes smaller, less smoke is generated at this time, and the purification power of the purifier can be reduced. Alternatively, when the processing speed is slower during laser processing, more smoke is generated, and the purification power of the purifier needs to be increased; conversely, when the processing speed of the laser processing increases, less smoke is generated at this time, and the purification power of the purifier can be reduced. Such a setting is to make the purification power of the purifier adapt to the amount of smoke generated by the laser processing equipment when it is processed with different processing parameters, which can effectively purify the generated smoke, and there is no need for the user to manually adjust the purification power of the purifier, making the control and use of the purifier more convenient, and there is no need to maintain a high purification power for a long time to operate, reducing energy consumption.

[0065] Therefore, it can be understood that according to the technical solution of the present invention, the purifier can automatically adjust the purification power according to the processing task to ensure that when the laser processing equipment adopts different processing parameters for processing, the smoke and gas generated can be filtered and purified by the purifier, and there is no need for manual control and adjustment of the purifier, thereby improving the control convenience of the purifier and realizing automation; and avoiding the purifier always maintaining a high purification power during the laser processing process, resulting in excessive energy consumption.

[0066] In one embodiment of the present application, a mapping relationship between parameters and purification power under different working modes can be preset, and the purification power can be adjusted according to the working mode, that is, the mapping relationship between processing parameters and required purification power under different modes is different. In step S20, step S20 may include: obtaining the current working mode, obtaining the mapping relationship between processing parameters and required purification power according to the current working mode, and then determining the required purification power based on the mapping relationship, generating corresponding adjustment instructions based on the purification power, and then adjusting the purification power of the purifier during laser processing. For example, the working mode includes a cutting mode and an engraving mode. The purification power requirements in the cutting mode and the engraving mode are different. There is a first mapping relationship between the processing parameters and the purification power in the cutting mode, and there is a second mapping relationship between the processing parameters and the purification power in the engraving mode. In step S20, the current working mode is obtained. If the current working mode is the cutting mode, the first expected purification power corresponding to the processing parameter is obtained according to the first mapping relationship, and the adjustment instruction of the purifier is generated based on the first expected purification power. The adjustment instruction is sent to the purifier to control the purifier to output the first expected purification power or a purification power greater than the expected purification power; if the current working mode is the engraving mode, the second expected purification power corresponding to the processing parameter is obtained according to the second mapping relationship, and the adjustment instruction of the purifier is generated based on the second expected purification power. The adjustment instruction is sent to the purifier to control the purifier to output the second expected purification power or a purification power greater than the expected purification power. Among them, in different working modes, the content of the purifier adjustment instruction output based on the processing parameters and the purifier configuration information is roughly the same.

[0067] Please refer to Figure 3 In some embodiments of the present application, the step S10 of obtaining the processing parameters in the processing task of the laser processing equipment includes:

[0068] Step S11, receiving processing parameters sent by laser processing equipment.

[0069] That is, in this embodiment, the processing parameters of the laser processing equipment obtained by the purifier when performing the processing task are sent directly to the purifier by the laser processing equipment; the laser processing equipment may continuously or periodically send the current processing parameters to the purifier during the execution of the task, or the adjusted processing parameters may be sent to the purifier when the processing parameters change; this setting method allows the purifier to more accurately respond to different processing parameters and adjust the purification power to the expected purification power; in addition, the laser processing equipment may send all the processing parameters of the processing task to the purifier in advance before starting the processing, so that the purifier can pre-set the purification power at different stages, and in the process of the laser processing equipment performing the processing task, the purification power of the purifier can be better adapted to the processing parameters of the laser processing equipment in real time.

[0070] Please refer to Figure 4 In one embodiment of the present application, the step S10 of obtaining the processing parameters in the processing task of the laser processing equipment includes:

[0071] Step S12, receiving processing parameters for the laser processing equipment to perform the processing task sent by the host computer.

[0072] In this embodiment, the processing tasks and corresponding processing parameters required to be performed by the laser processing equipment are set in the host computer. Before the laser processing equipment starts processing, the host computer sends the processing tasks and processing parameters to the laser processing equipment and the purifier. The laser processing equipment operates according to the processing parameters to perform the processing tasks, and the purifier adapts the purification power of different processing stages according to the processing tasks and processing parameters. Therefore, the laser processing equipment can operate at the pre-adapted purification power at different stages of the processing task, so that the purifier can better purify the smoke generated in different processing stages and improve the purification effect.

[0073] It should be noted that in the embodiments of the present application, the size relationship of the step numbers does not completely represent the order of execution of the steps. For example, step S11 and step S12 represent two different implementations of step S10; and as in the embodiments below, step S21, step S22 and step S23 represent different implementations of step S20.

[0074] In one embodiment of the present application, the processing parameters include processing speed and processing power.

[0075] Specifically, during laser processing, such as laser engraving and laser cutting, according to the size differences of the engraving depth, cutting thickness or incision width at different positions of the desired product pattern or shape, the processing parameters of the laser processing need to be adjusted during the laser processing, wherein the processing parameters include at least one of the processing power and the processing speed. Among them, when the processing power is greater during laser processing, more light is emitted during processing, the stronger the laser energy is, the more smoke is generated, and at this time, the purification power of the purifier needs to be increased; conversely, when the processing power of the laser processing becomes smaller, less smoke is generated at this time, and the purification power of the purifier can be reduced to save energy and reduce the energy consumption of the purifier.

[0076] When the laser processing speed is slower, that is, the longer the stay time at the processing position, the more lasers are emitted from the processing position, and the more smoke is generated. At this time, the purification power of the purifier needs to be increased; conversely, when the laser processing speed increases, the smoke generated is less, and the purification power of the purifier can be reduced to save energy and reduce the energy consumption of the purifier.

[0077] Based on this, the step S20 of determining the purification power of the laser processing equipment during the processing task according to the processing parameters in the above embodiment includes: determining the purification power of the laser processing equipment during the processing task according to the processing speed and / or the processing power. Different implementation methods of this step will be described below.

[0078] Please refer to Figure 5 In one embodiment of the present application, the step S20 of determining the expected purification power of the laser processing equipment during the processing task according to the processing parameters in the above embodiment includes:

[0079] Step S21, obtaining the expected purification power corresponding to the target processing power according to the mapping relationship between the processing power and the purification power.

[0080] In this embodiment, the purification power can be obtained according to the mapping relationship between the processing power and the purification power; or the purification power can be obtained according to the power range in which the processing power is located and the mapping relationship between the power range and the purification power. For example, at least two power ranges can be set in advance, and the power range in which the processing power is located can be determined. The expected purification power required to be set for the purifier is obtained according to the obtained power range, and then the purification power of the purifier is adjusted to the expected purification power to match the processing power, so as to ensure that the purifier can play an effective purification role and absorb and purify smoke and gas to a greater extent.

[0081] Please refer to Figure 6 In one embodiment of the present application, the step S20 of determining the expected purification power of the laser processing equipment during the processing task according to the processing parameters in the above embodiment includes:

[0082] Step S22, obtaining the expected purification power corresponding to the target processing speed according to the mapping relationship between the processing speed and the purification power.

[0083] In this embodiment, the purification power can be obtained according to the mapping relationship between the processing speed and the purification power; or the purification power can be obtained according to the speed range in which the processing speed is located and the mapping relationship between the speed range and the purification power. For example, at least two speed ranges can be set in advance, and at least two purification powers corresponding to the at least two speed ranges are set one by one. The expected purification power required to be set for the purifier is obtained according to the acquired speed range, and then the purification power of the purifier is adjusted to the expected purification power to match the processing speed, so as to ensure that the purifier can play an effective purification role and absorb and purify smoke and gas to a greater extent.

[0084] Please refer to Figure 7 In one embodiment of the present application, the step S20 of determining the expected purification power of the laser processing equipment during the processing task according to the processing parameters in the above embodiment includes:

[0085] Step S23, according to the mapping relationship among the processing power, the processing speed and the purification power, the expected purification power corresponding to the target processing power and the target processing speed is obtained.

[0086] In this embodiment, the purification power of the purifier is matched according to the comprehensive consideration of the processing power and the processing speed of the same processing stage. For example, the first purification power can be obtained according to the mapping relationship between the power interval where the processing power is located and the purification power, and the second purification power can be obtained according to the mapping relationship between the speed interval where the processing speed is located and the purification power of the same processing stage. The larger purification power of the first purification power and the second purification power is used as the expected purification power, and the purification power of the purifier is adjusted to the expected purification power. Alternatively, the average value of the first purification power and the second purification power is taken or the expected purification power is obtained through other operation relationships. In some embodiments, an operation logic for obtaining the purification power through the processing power and the processing speed can also be established, and the purification power that matches the processing power and the processing speed is matched through the operation logic, which is not limited here. For example, a functional relationship between the processing power, the processing speed and the purification power can be established in advance, in which the processing power and the processing speed are independent variables, and the purification power is the dependent variable. After the processing power and the processing speed are determined, the corresponding purification power can be calculated.

[0087] In some embodiments of the present application, different processing materials generate different amounts of smoke during the processing process. For example, the amount of smoke generated during wood processing is greater than the amount of smoke generated during plastic and metal processing. In step S20 of determining the purification power of the laser processing equipment during the processing task according to the processing parameters, the expected purification power corresponding to the target processing power and the target processing speed can also be obtained according to the mapping relationship between the processing material, processing power, processing speed and purification power. For example, the mapping relationship between the processing speed, processing power and purification power is different for different processing materials. The processing material can be obtained first, and then the mapping relationship between the processing speed, processing power and purification power under the processing material can be obtained. After the processing power and processing speed are determined, the corresponding purification power can be calculated.

[0088] Please refer to Figures 5 to 7 After the expected purification power is determined through processing parameters, during the process of the laser processing equipment performing the processing task, the purifier works synchronously according to the purification power to ensure that the purifier can play an effective purification role and absorb and purify smoke and gas to a greater extent.

[0089] Among them, in step S30, the step of synchronously working according to the expected purification power includes:

[0090] Step S31, adjusting to the expected purification power and performing purification.

[0091] In this embodiment, the purifier can directly adjust the purification power to the expected purification power. With this adjustment method, the purifier can achieve stepless adjustment of the purification power, thereby making the matching accuracy between the purification power and the processing parameters of the laser processing equipment higher, which is beneficial to improving the purification effect.

[0092] Please refer to Figures 5 to 7 In some embodiments, in step S30, the step of synchronously operating according to the expected purification power may also include:

[0093] Step S32, adjusting the working gear to the gear of the expected purification power.

[0094] In this setting method, the purifier pre-sets the gear configuration information, that is, the purifier is pre-set to operate in at least two different working gears, each working gear corresponds to a purification power of the purifier, and after determining the expected purification power required to operate the purifier, the working gear corresponding to the expected purification power is determined, and then the purifier is adjusted to the working gear for operation, which can make the power adjustment of the purifier relatively convenient.

[0095] Please refer to Figure 8 In some embodiments of the present application, the control method further includes:

[0096] Step S60, after the laser processing equipment completes processing and the delayed shutdown time has elapsed, the laser processing equipment stops working.

[0097] When the laser processing equipment completes processing of the workpiece, the purifier can be turned off. Usually, there will be smoke and dust when the laser processing is completed. If the purifier is turned off immediately after the laser processing equipment completes processing, some smoke and dust will remain in the processing environment. In this embodiment, the purifier is turned off after the laser processing equipment completes processing to absorb and purify the remaining smoke and dust.

[0098] Please refer to Fig. 9 In some embodiments of the present application, after the laser processing equipment completes processing and the delayed shutdown time has passed, before the step of stopping the work, the step also includes:

[0099] Step S40, obtaining the delayed closing time, the delayed closing time is sent by the host computer to the laser processing equipment, and then sent by the laser processing equipment to the purifier, or sent by the host computer to the purifier.

[0100] In this embodiment, the host computer is provided with a delayed closing time of the purifier, and the laser processing equipment is respectively connected to the host computer and the purifier for communication. At this time, the host computer can send the delayed closing time to the laser processing equipment, and then the laser processing equipment sends the delayed closing time to the purifier; optionally, the host computer can be connected to the purifier for communication, and the host computer directly sends the extended closing time to the purifier, or the purifier can obtain the delayed closing time, so that the laser processing equipment will delay closing according to the obtained extended closing time after completing the processing task.

[0101] Among them, the delayed shutdown time of the purifier can be directly set in the upper computer, or the delayed shutdown time of the purifier on the server can be synchronized by the upper computer and written into the upper computer software. For example, before the upper computer sends the processing parameters and the delayed shutdown time of the purifier to the laser processing equipment, it first synchronizes the configuration information of the purifier from the server. The configuration information includes at least the delayed shutdown time of the purifier, and can also include the gear information of the purifier, the purification power corresponding to each gear, and the purification power within the delayed shutdown time.

[0102] Please refer to Fig. 9 In some embodiments, after starting the host computer software in the host computer and before sending the processing task and processing parameters to the laser processing equipment, it is first determined whether the host computer is set with a delayed shutdown time of the purifier. If the delayed shutdown time of the purifier has been set, the above step S40 is executed. If the delayed shutdown time of the purifier has not been set in the host computer, the following step S50 is executed.

[0103] Step S50, generating a delayed closing time according to the processing parameters and / or the purification power.

[0104] Among them, if the purifier does not obtain the delayed closing time, the purifier can automatically generate the delayed closing time according to the processing parameters of the laser processing equipment; it can also automatically generate the delayed closing time of the purifier according to the purification power when the processing is completed; it can also be the processing parameters of the laser processing equipment and the purification power of the purifier when the processing is completed. The delayed closing time of the purifier is set in this way, so that the purifier can better perform purification operations according to the amount of smoke generated during the processing and its own purification power, avoiding the preset delayed closing time before the laser processing being too short to completely purify the remaining smoke after the laser processing is completed, and avoiding the preset delayed closing time being too long, resulting in the purifier continuing to turn on after the residual smoke is purified. In some embodiments, it is also possible to directly generate the delayed closing time through step S50 without determining whether a delayed closing time is set.

[0105] Different implementations of step S50 will be described below.

[0106] In some embodiments, the step of generating a delayed closing time for the purifier according to the processing parameters of the laser processing equipment can be to obtain a target delayed closing time according to the processing power in a preset time period at the end of the processing or before the end of the processing, and after the laser processing equipment completes the processing task, the purifier is delayed to close with the target delayed closing time. For example, at least two power intervals can be pre-set, and the delayed closing time corresponding to each power interval can be set accordingly. The target delayed closing time required to be set for the purifier is obtained according to the power interval in which the processing power before the laser processing equipment completes the processing task. After the laser processing equipment completes the processing task, the purifier is delayed to close with the target delayed closing time to ensure that the purifier can effectively absorb and purify the residual smoke and gas after the laser processing is completed. Among them, the preset time period can be the entire processing time, or the second half of the time, or the processing time period in which the processing will generate smoke.

[0107] In some embodiments, the step of generating a delayed closing time according to the processing parameters of the laser processing equipment by the purifier can be to obtain the target delayed closing time by judging the processing speed at the end of the processing or within a preset time period before the end of the processing, or to synchronously judge whether there is a delayed closing time when the processing parameters of the laser processing equipment are received, and if not, the delayed closing time is generated based on the processing parameters, and after the laser processing equipment completes the processing task, the purifier is delayed to close with the target delayed closing time. For example, at least two speed intervals can be pre-set, and the delayed closing time corresponding to each speed interval can be set accordingly, and the target delayed closing time required to be set by the purifier is obtained according to the speed interval where the processing speed before the laser processing equipment completes the processing task. After the laser processing equipment completes the processing task, the purifier is delayed to close with the target delayed closing time to ensure that the purifier can effectively absorb and purify the residual smoke and gas after the laser processing is completed.

[0108] In some embodiments, the purifier can set a mapping relationship between the laser processing power and processing speed and the purification power according to the processing power and processing speed in a preset time period at the end of processing or before the end of processing, and obtain a delayed closing time corresponding to the laser processing state according to the laser processing power and processing speed. For example, the first delayed closing time is obtained according to the mapping relationship between the processing power and the delayed closing time, and the second delayed closing time is obtained according to the mapping relationship between the processing speed and the delayed closing time, and the larger delayed closing time between the first delayed closing time and the second delayed closing time is used as the target delayed closing time. Alternatively, the target delayed closing time is obtained by taking the average of the first delayed closing time and the second delayed closing time or by other operational relationships. Alternatively, the delayed closing time and the processing power and processing speed have a mapping relationship, in which the processing power and processing speed are independent variables, and the delayed closing time is the dependent variable. Among them, the mapping relationship can be a table format or a function.

[0109] In addition, it should be noted that in some embodiments, the processing parameters of the laser processing process may also include processing patterns, processing materials and other parameters, and a mapping relationship between these processing parameters and the delayed closing time may be established in advance, and then the corresponding delayed closing time may be determined based on these processing parameters. For example, different processing materials may have different delayed closing times.

[0110] In some embodiments, the purifier determines the delayed purification time according to the purification power during the delayed shutdown period. The purification power of the purifier during the delayed shutdown period can be preset; or the purifier can continue to operate according to the purification power when the laser processing equipment completes the processing task, and the delayed shutdown time of the purifier is determined according to the purification power.

[0111] In some embodiments, the purifier can comprehensively determine the delayed closing time of the purifier based on the processing parameters of the laser processing equipment at the end of processing or in a preset time period before the end of processing and the purification power of the purifier during the delayed closing period. Among them, the third delayed closing time can be determined according to the processing parameters. The method for determining the third delayed closing time refers to the aforementioned embodiment of determining the extended closing time according to at least one of the processing power and the processing speed, which is not repeated here; the fourth delayed closing time is determined according to the purification power, and the larger delayed closing time between the third delayed closing time and the fourth delayed closing time is used as the target delayed closing time. Alternatively, the target delayed closing time is obtained by taking the average of the third delayed closing time and the fourth delayed closing time or by other calculation relationships.

[0112] Please refer to Fig.10 In some embodiments, the aforementioned step S50 of generating a delayed closing time according to the processing parameters and / or the purification power includes:

[0113] Step S51, obtaining a preset first delayed closing time, where the first delayed closing time is the longest delayed closing time allowed by the purifier;

[0114] Step S52, generating a second delayed closing time according to the processing parameters and / or purification power;

[0115] Step S53, if the second delayed closing time does not exceed the first delayed closing time, the second delayed closing time is used as the delayed closing time;

[0116] Step S54: if the second delayed closing time exceeds the first delayed closing time, the first delayed closing time is used as the delayed closing time.

[0117] In this embodiment, the first delayed closing time of the purifier can be set in the host computer, and the first delayed closing time can be sent to the purifier or sent to the purifier via the laser processing equipment. When the host computer does not obtain the delayed closing time of the current processing task, the purifier can automatically generate the second delayed closing time of the purifier according to the processing parameters of the laser processing equipment; it can also automatically generate the second delayed closing time of the purifier according to the purification power of the purifier during the delayed closing process; it can also be the processing parameters of the laser processing equipment and the purification power of the purifier during the delayed closing process. The second delayed closing time is confirmed in a similar way to the above-mentioned embodiment, which will not be repeated here.

[0118] After confirming the second delayed closing time and the first delayed closing time, the size relationship between the second delayed closing time and the first delayed closing time can be determined, and the minimum value between the second delayed closing time and the first delayed closing time is used as the delayed closing time of the purifier. After the laser processing equipment completes the processing task, the purifier is delayed according to the delayed closing time and then closed, so that the purifier can only delay the first delayed closing time at most when the laser processing is completed. Avoid the purifier opening time for a long time. In addition, considering that the smoke generated during laser processing is in an active state, part of the smoke will escape to the laser processing equipment and the external environment of the purifier, and the amount of smoke absorbed and purified by the purifier will be less than the actual amount of smoke generated during laser processing. At this time, if the delayed closing time of the purifier is set according to the amount of smoke generated by the laser processing parameters, it is possible that the purification time that actually produces an effective purification effect is shorter than the delayed closing time generated by the purifier, resulting in energy waste; at this time, by setting the first delayed closing time of the purifier, it is ensured that the purifier produces an effective purification effect during the delayed closing time period, improve energy utilization efficiency, and reduce energy consumption.

[0119] In some embodiments, after determining the delayed shutdown time of the purifier based on the processing parameters and purification power, the purifier can send the delayed shutdown time to the host computer, and the host computer saves the delayed shutdown time or uploads it to the server for storage, so that the parameter can be directly sent to the purifier when the same processing task is performed next time.

The purifier 1 can be used to perform the purification operation when the laser processing equipment 2 starts the laser processing, or the purifier 1 can be started before the laser processing, or the purifier 1 can be used to perform the purification operation after the laser processing equipment 2 starts the laser processing for a period of time. The purifier 1 is connected to the laser processing equipment 2 for communication, which can be a wired connection or a wireless connection, such as using Bluetooth connection or connecting the purifier 1 and the laser processing equipment 2 to the same local area network; so that the purifier 1 and the laser processing equipment 2 can transmit signals, and the control signal can be sent to the purifier 1 by the laser processing equipment 2, and it can also be used to enable the purifier 1 to directly obtain the processing parameters or other information of the laser processing equipment 2. Among them, the purifier 1 can automatically adjust the purification power according to the processing task to ensure that when the laser processing equipment 2 adopts different processing parameters for processing, the smoke and gas generated can be filtered and purified by the purifier 1, and there is no need to manually control and adjust the purifier 1, which improves the control convenience of the purifier 1 and realizes automation; and avoids the purifier 1 always maintaining a high purification power during the laser processing process, resulting in excessive energy consumption.
