[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more, and the term "multiple" refers to two or more; the terms "connected", "fixed", etc. should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0038] Existing laser processing equipment will generate dust during laser processing, so dust needs to be absorbed by a dust suction device. However, the existing dust suction device is generally provided with dust suction capacity by a vacuum cleaner or a central vacuum system. The dust suction capacity provided by the vacuum cleaner or the central vacuum system is constant. For the vacuum cleaner or the central vacuum system, the dust suction capacity, or the dust suction power, it provides to a single laser processing equipment is generally constant, either on or off; secondly, even if a variable frequency vacuum cleaner is used, its responsiveness cannot meet the corresponding requirements of laser processing. The fan needs to change the speed, which is on the order of several seconds to tens of seconds. Generally speaking, no one will change the frequency to change the dust suction capacity (air volume and negative pressure) during the processing process.

[0039] However, the demand for dust collection changes dynamically during the laser processing process. For example, general laser processing equipment includes a moving platform. During the period of platform movement, the laser does not emit light, and there is no need for dust collection at this time. Or, for laser processing equipment using a galvanometer, when the galvanometer finishes processing one area and jumps to the next processing area, this empty jump means no light or processing, and there is no need for dust collection at this time. When the laser starts to emit light, processing dust will be generated, and there is a need for dust collection at this time.

[0040] Based on this, the present application provides a dust suction device for laser processing equipment. When the dust suction capacity remains unchanged and the dust suction demand during the laser processing process changes dynamically, the dust suction device can store the dust suction capacity when the dust suction demand is low and burst it out when the dust suction demand is high, thereby improving the dust suction effect. That is, the dust suction device of the present application can output high dust suction capacity when the dust suction demand is high, and output low dust suction capacity when the dust suction demand is low, while the total dust suction capacity remains unchanged, but the suction effect will be better, and there is no need to change the structure of devices such as the vacuum cleaner or the central dust suction system.

[0041] Reference Figure 1 As shown, an embodiment of the present application discloses a laser processing device, which is configured as a laser cutting device or a laser drilling device. The laser processing device includes a workbench 300, a laser processing device 200 and a dust suction device 100. The workbench 300 is used to place a workpiece to be processed, the laser processing device 200 is used to emit a laser toward the workbench 300 to perform laser processing on the workpiece to be processed placed on the workbench 300 through the laser, and the dust suction device 100 is used to absorb dust generated during the laser processing.

[0042] Reference Figure 2 As shown, the dust collection device 100 includes a dust collection hood 1, a dust collector 3 and a dust collection assembly 2, and the dust collection assembly 2 includes a pressure container 21, a first valve 22 and a second valve 23. The dust collector 3 is connected to the dust collection hood 1 through a first pipeline 4 to form a first dust collection pipeline. The pressure container 21 is provided with a first end 211 and a second end 212, the first end 211 is connected to the dust collection hood 1 through a second pipeline 5, and the second end 212 is connected to the dust collection hood 1 through a third pipeline 6 to form a second dust collection pipeline, and the second dust collection pipeline is used to store energy during a period of low dust collection demand. The first valve 22 is arranged at the input end of the pressure container 21, and is used to control the on and off of the first dust collection pipeline and the second dust collection pipeline, that is, the first valve 22 can control the connection or disconnection between the dust collection hood 1 and the pressure container 21 and the dust collector 3, so that the dust collection device 100 can be switched between the energy storage state and the dust collection state. The second valve 23 is arranged at the output end of the pressure container 21, and is used to control the airflow direction of the second dust collection pipeline.

[0043] In this embodiment, by providing a first dust suction pipeline and a second dust suction pipeline, when the laser processing device 200 does not emit a laser, the dust suction demand is low, the first valve 22 can be closed, and there is no need to perform a dust suction operation on the workbench 300. At this time, the vacuum cleaner 3 is still providing dust suction capacity, so that the pressure vessel 21 is pumped into a negative pressure state, the second dust suction pipeline begins to store energy, and the dust suction device 100 is in an energy storage state. When the laser processing device 200 emits a laser to achieve laser processing, it is necessary to perform a dust suction operation on the workbench 300. At this time, the dust suction demand is high, and the first valve 22 can be opened so that the first dust suction pipeline and the second dust suction pipeline provide dust suction capacity at the same time, and the dust suction device 100 is in a dust suction state. In this embodiment, when the dust suction device 100 is in the dust suction state, the dust suction capacity is provided by the first dust suction pipeline and the second dust suction pipeline at the same time, thereby improving the dust suction efficiency.

[0044] Continue to refer to Figure 2 As shown, the dust collecting device 100 further includes a fourth pipeline 7. The dust collector 3 is connected to the first valve 22 via the first pipeline 4, the first end 211 of the pressure container 21 is connected to the first valve 22 via the second pipeline 5, and the second end 212 of the pressure container 21 is connected to the dust collector 3 via the third pipeline 6. The second valve 23 is disposed on the third pipeline 6, so that the pressure container 21, the second valve 23 and the first pipeline 4 are connected in parallel. The dust collecting hood 1 is connected to the first valve 22 via the fourth pipeline 7.

[0045] In this embodiment, the first valve 22 can be set as a two-way valve, and the on-off of the first dust suction pipeline and the second dust suction pipeline can be controlled by controlling the opening and closing of the first valve 22, that is, the on-off between the dust hood 1 and the pressure container 21 and the dust collector 3 can be controlled, and the working state of the first valve 22 can be opened at a certain opening in addition to opening and closing, so as to control the dust suction flow of the dust hood 1 and the energy storage state (power diversion) of the pressure container 21. The second valve 23 can be set as a one-way valve to limit the airflow from the pressure container 21 end to the dust collector 3 through the one-way valve. The dust collector 3 can be set as a centrifuge or a central dust collection system.

[0046] In order to facilitate the control of the opening of the first valve 22, the dust collection component 2 also includes a cylinder 24, which is used to control the opening, closing or opening degree of the first valve 22. The start of the cylinder 24 can be triggered based on the gate signal of the laser light, or can be triggered by the host computer through certain logic to control the opening and closing of the dust collection as needed.

[0047] This embodiment is a system that actively controls the opening and closing of the vacuum cleaner. When the laser processing equipment is not performing light processing, the first valve 22 is actively closed, and the second vacuum cleaner pipeline starts to store energy. When the pressure vessel 21 is fully charged, the capacity of the vacuum cleaner or the central vacuum cleaner system will no longer be consumed (the vacuum cleaner flow rate will not be consumed). When multiple devices are producing at the same time in the customer's factory, the power of the vacuum cleaner or the central vacuum cleaner system can be reduced, thereby saving energy and reducing emissions.

[0048] In some embodiments, reference Figure 3 As shown, two first valves 22 may also be provided, wherein one first valve 22 is provided at the first end 211 of the pressure container 21, and the first valve 22 is used to control the on-off between the dust hood 1 and the pressure container 21. The other first valve 22 is provided in the first pipeline 4, and the first valve 22 is used to control the on-off between the dust hood 1 and the vacuum cleaner 3.

[0049] In some embodiments, reference Figure 4 and Figure 5 As shown, the first valve 22 can be directly connected to the first end 211 of the pressure vessel 21, and the first valve 22 can be set as a three-way valve. The second valve 23 can be directly connected to the second end 212 of the pressure vessel 21, and the cylinder 24 can be directly connected to the first valve 22, so that the pressure vessel 21, the first valve 22, the second valve 23 and the cylinder 24 form an integrated structure, so as to facilitate the installation of the dust collection assembly in the dust collection device. During installation, the vacuum cleaner 3 is connected to one of the ports of the first valve 22 through the first pipeline 4, the vacuum cleaner 3 is connected to the second valve 23 through the third pipeline 6, and the dust hood 1 is connected to the other port of the first valve 22 through the fourth pipeline 7.

[0050] In actual application scenarios, when the laser processing device 200 is in a non-lighting state, that is, when no laser processing is performed, there is no need to perform vacuuming operations on the workbench 300. At this time, the vacuuming demand is low, and the first valve 22 can be controlled to close, that is, the first vacuuming pipeline and the second vacuuming pipeline are shut off, but the vacuum cleaner 3 is still providing vacuuming capabilities through the third pipeline 6. At this time, the interior of the pressure vessel 21 will be evacuated into a negative pressure state, and the second vacuuming pipeline is in an energy storage state.

[0051] When the laser processing device 200 starts the laser processing, the dust suction needs to be high, and the first valve 22 can be controlled to open to connect the first dust suction pipeline and the second dust suction pipeline. That is, the dust hood 1 is connected to the dust collector 3 through the fourth pipeline 7 and the first pipeline 4, and the dust hood 1 is connected to the pressure container 21 through the fourth pipeline 7 and the second pipeline 5. The vacuum cleaner 3 provides dust suction capability, and the pressure container 21 also provides dust suction capability. The first dust suction pipeline and the second dust suction pipeline both provide dust suction capability for the dust hood 1.

[0052] Compared with ordinary dust suction devices, this embodiment adds a second dust suction pipeline, which can store dust suction capacity in the energy storage stage. Therefore, the dust suction capacity stored in the second dust suction pipeline can improve the dust suction capacity and dust suction efficiency of the laser processing equipment during processing without adding a new dust suction machine or central dust suction system capacity. At the same time, while maintaining the total dust suction capacity of the laser processing equipment during processing, the dust suction capacity is stored when there is no dust suction demand, which reduces the waste of dust suction capacity and saves energy.

[0053] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
