Description

Technical Field

[0001] The present application belongs to the field of laser processing technology, and in particular, relates to a laser processing device and a control method thereof, and a computer-readable storage medium. Background Art

[0002] Laser processing equipment uses laser as a processing medium to achieve the purpose of processing. The laser processing equipment has a processing space inside. When the laser processing equipment is in use, in order to prevent the moving mechanical parts inside the processing space of the laser processing equipment or the high-energy laser emitted by the laser component from spilling out and injuring people, an openable cover will be added to the laser processing equipment to close the processing space.

[0003] However, although the existing laser processing equipment has added a cover for closing the processing space, the user can still open it at will during the laser processing process. In this way, during the laser processing process, if the user opens the cover, the laser emitted by the laser component will cause certain harm to the users around the laser processing equipment and may affect the health of the users. Summary of the invention

[0004] In order to address the deficiencies in the prior art, the present application provides a laser processing device and a control method thereof, as well as a computer-readable storage medium that can improve safety.

[0005] In a first aspect, an embodiment of the present application provides a control method for a laser processing equipment, wherein a processing space is provided therein, the laser processing equipment comprises a blocking member, a body and a locking unit, the body is used to perform a processing task, the processing space is defined by the body and the blocking member, the blocking member comprises an open state and a closed state, the locking unit is provided on at least one of the body and the blocking member, the locking unit comprises an unlocked state and a locked state, the unlocked state enables the blocking member to switch between the open state and the closed state, and the locked state enables the blocking member to maintain the closed state; the control method comprises: controlling the locking unit to be in an unlocked state or a locked state according to the state of the blocking member detected by a first sensor and / or the progress state of the processing task.

[0006] When the locking unit is in the locked state, the blocking member remains in the closed state, that is, the blocking member cannot be opened by the user. In this way, the risk of the blocking member being opened by the user during the laser processing of the laser processing equipment and causing the laser to overflow out of the processing space is reduced, thereby improving the safety of the laser processing equipment during the processing.

[0007] According to the state of the blocking member detected by the first sensor and the progress state of the processing task, the locking unit is automatically controlled to be in an unlocked state or a locked state, thereby improving the intelligence and automation of laser processing.

[0008] The state of the locking unit is controlled by the progress state of the processing task instead of using a sensor sensing method, which is beneficial to simplifying the structure of the laser processing equipment.

[0009] In combination with the first aspect, in a possible implementation of the present application, controlling the locking unit to be in an unlocked state or a locked state based on the state of the blocking member detected by the first sensor includes: if the state of the blocking member is a closed state, controlling the locking unit to be in a locked state.

[0010] The first sensor automatically senses that the blocking member is in a closed state, and controls the locking unit to be in a locked state, thereby achieving precise control and avoiding the situation where the user mistakenly judges that the blocking member is closed when it is actually open, thereby further improving the safety of laser processing.

[0011] In combination with the first aspect, in a possible implementation of the present application, controlling the locking unit to be in an unlocked state or a locked state according to the process status of the processing task includes: if the process status of the processing task is any one of a paused state, a stopped state and a completed state, controlling the locking unit to be in an unlocked state.

[0012] If the process status of the processing task is any one of the paused state, the stopped state and the completed state, the locking unit is automatically controlled to be in the unlocked state, so that the user can open the blocking member to check the laser processing equipment and the workpiece.

[0013] In combination with the first aspect, in a possible implementation of the present application, controlling the locking unit to be in an unlocked state or a locked state based on the state of the blocking member and the progress state of the processing task detected by the first sensor includes: if the state of the blocking member is a closed state and the progress state of the processing task is a continuing state, controlling the locking unit to be in a locked state.

[0014] If the state of the blocking member is the closed state and the progress state of the processing task is the continued state, that is, when the machine body needs to continue the processing task, the locking unit is controlled to be in the locked state, which facilitates the processing.

[0015] In combination with the first aspect, in a possible implementation of the present application, after controlling the locking unit to be in a locked state, the control method also includes: controlling the second sensor to detect the state of the locking unit; if the locking unit is in the locked state, controlling the machine body to perform the processing task; if the locking unit is in the unlocked state, controlling the reminder device to output a warning message.

[0016] When the locking unit is not locked, there is a risk that the blocking member may be easily opened. Only after the second sensor senses that the locking unit is in a locked state will the machine body be controlled to execute the processing task, thereby reducing the possibility that the machine body starts to execute the processing task when the locking unit is not locked, thereby further improving the safety of laser processing.

[0017] After the locking unit is controlled to be in the locked state, if the locking unit is in the unlocked state, it means that an abnormality occurs in the locking unit, and a warning message is outputted through the reminding device to remind the user that the locking unit is abnormal.

[0018] In combination with the first aspect, in a possible implementation of the present application, the control method further includes: detecting a current value of the locking unit, and if the current value of the locking unit is greater than a preset value, controlling a reminder device to output a warning message.

[0019] After the locking unit is controlled to be in a locked state, if the current value of the locking unit is greater than a preset value, it means that an abnormality occurs in the locking unit, and a warning message is output through a reminder device to remind the user that the locking unit is abnormal.

[0020] In a second aspect, an embodiment of the present application provides a laser processing device, wherein a processing space is provided therein, and the laser processing device comprises: a blocking member, comprising an open state and a closed state; a body, used to perform a processing task; the processing space is defined by the body and the blocking member; a first sensor, provided on the body, used to detect whether the blocking member is in the open state or the closed state; a locking unit, provided on at least one of the body and the blocking member, comprising an unlocked state and a locked state, wherein the unlocked state enables the blocking member to switch between the open state and the closed state, and the locked state enables the blocking member to maintain the closed state; a processor, electrically connected to the first sensor and the locking unit, and the processor is used to execute the control method as described above.

[0021] In combination with the second aspect, in a possible implementation of the present application, the laser processing equipment also includes an interaction unit connected to both the processor and the body, and the interaction unit is used for a user to trigger a processing instruction. The processor is also used to control the process status of the processing process according to the start processing instruction.

[0022] The interaction between the laser processing equipment and the user is realized through the interactive unit, thereby improving the convenience of using the laser processing equipment.

[0023] In combination with the second aspect, in a possible implementation of the present application, the body includes a workbench and a casing, the casing is provided with an opening, and the blocking member is closed on the opening when the blocking member is in the closed state; the laser processing equipment also includes a second sensor, which is electrically connected to the processor and is used to detect whether the locking unit is in the unlocked state or the locked state.

[0024] The workbench and the casing are set separately, which facilitates the manufacture and transportation of laser processing equipment, and also facilitates the maintenance and replacement of the workbench and the casing; by setting a second sensor, the status of the locking unit is detected in real time to confirm whether it is in an unlocked state or a locked state. If the locking unit is in an abnormal state, it can be discovered in time.

[0025] In combination with the second aspect, in a possible implementation of the present application, the locking unit includes a first locking part and a second locking part which can move relative to each other, the first locking part is arranged on the machine body, and the second locking part is arranged on the blocking member; the position where the first locking part moves relative to the second locking part includes an unlocking position and a locking position, when the first locking part moves to the unlocking position relative to the second locking part, the locking unit is in the unlocking state; when the first locking part moves to the locking position relative to the second locking part, the locking unit is in the locking state, and the blocking member is closed on the machine body.

[0026] The switching between the unlocked state and the locked state of the locking unit is achieved through the relative movement of the first locking part with respect to the second locking part, and the structure is simple.

[0027] In combination with the second aspect, in a possible implementation of the present application, the first locking portion includes a driving body and a telescopic rod that are connected to each other, the driving body is fixed on the housing, and the driving body can drive the telescopic rod to move in a direction close to or away from the second locking portion, the second locking portion includes a locking hole provided on the blocking member, and the position of the telescopic rod moving relative to the second locking portion includes the unlocking position and the locking position, when the telescopic rod is extended to the locking position, the telescopic rod at least partially passes through the locking hole, and the locking unit is in the locking state; when the telescopic rod is retracted to the unlocking position, the locking unit is in the unlocking state.

[0028] The locking unit is a limit switch, which drives the telescopic rod to perform telescopic movement through the driving body, so that the locking unit can be quickly switched between the unlocked state and the locked state with high movement accuracy.

[0029] When the locking unit is in a locked state, the telescopic rod at least partially passes through the locking hole, and the locking hole limits the telescopic rod, thereby reducing the possibility of the telescopic rod escaping from the blocking member.

[0042] Please refer to Figure 1 and Figure 2 The laser processing equipment 100 provided in the embodiment of the present application processes a workpiece (not shown) by using laser as a processing medium, and the processing processes include but are not limited to cutting, engraving, indentation and other processes. In this embodiment, the laser processing equipment 100 is a desktop laser cutting machine. In other embodiments, the laser processing equipment 100 includes but is not limited to other laser processing devices, and this application does not limit this.

[0043] The laser processing device 100 has a processing space therein. The laser processing device 100 includes a body 1001, a blocking member 1003, a first sensor 1004, a locking unit 1005, a second sensor 1006 and a control system 1009. The body 1001, the first sensor 1004, the locking unit 1005, and the second sensor 1006 are respectively connected to the control system 1009 for communication.

[0044] The machine body 1001 is used to perform a processing task. The blocking member 1003 includes a closed state and an open state. The first sensor 1004 is arranged on the machine body 1001, and is used to detect whether the blocking member 1003 is in an open state or a closed state. The locking unit 1005 is arranged on at least one of the machine body 1001 and the blocking member 1003. The locking unit 1005 includes an unlocked state and a locked state. The unlocked state allows the blocking member 1003 to switch between an open state and a closed state, and the locked state allows the blocking member 1003 to maintain the closed state. The second sensor 1006 is used to detect the state of the locking unit 1005. The control system 1009 controls the processing process of the machine body 1001 according to the state of the blocking member 1003 detected by the first sensor 1004 and the state of the locking unit 1005 detected by the second sensor 1006.

[0045] It can be understood that in other embodiments of the present application, the second sensor 1006 can be omitted.

[0046] The processing space is defined by the machine body 1001 and the blocking member 1003. The processing space is defined by the machine body 1001 and the blocking member 1003, which means that the machine body 1001 and the blocking member 1003 can be jointly enclosed to form the processing space.

[0047] The blocking member 1003 can move relative to the machine body 1001, so that the blocking member 1003 can be switched between a closed state and an open state. When the blocking member 1003 is closed to the machine body 1001, the blocking member 1003 is in a closed state, and the blocking member 1003 and the machine body 1001 are jointly enclosed to form a processing space. When the blocking member 1003 is opened relative to the machine body 1001, the blocking member 1003 is in an open state.

[0048] The blocking member 1003 is in a closed state, which means that the blocking member 1003 is closed on the body 1001. When the blocking member 1003 is in a closed state, the processing space is enclosed by the body 1001 and the blocking member 1003 to form a closed space, thereby preventing the laser from overflowing (emitting) outside the processing space during laser processing by the laser processing device 100, reducing the risk of users around the laser processing device 100 being injured by the laser, and improving the processing safety of the laser processing device 100.

[0049] The blocking member 1003 is in the open state, which means that the blocking member 1003 is open relative to the body 1001. When the blocking member 1003 is in the open state, if the laser processing device 100 performs laser processing, the laser will overflow into the external space of the body 1001.

[0050] In this embodiment, the body 1001 includes a housing 10, a workbench 20, a track device 30 and a laser processing device 40. The housing 10 is arranged on the workbench 20. The workbench 20 is used to carry a workpiece. The track device 30 is arranged on the workbench 20, and the laser processing device 40 is arranged on the track device 30 for laser processing the workpiece. The laser processing device 40 can move relative to the track device 30, and the track device 30 can move relative to the workbench 20. The housing 10 and the workbench 20 are arranged separately, which facilitates the manufacture and transportation of the laser processing equipment 100, and also facilitates the maintenance and replacement of the workbench 20 and the housing 10.

[0051] The housing 10 is provided with an opening 11 for conveniently taking and placing workpieces, etc. The housing 10 can be arranged integrally with the workbench 20, or can be arranged separately. In the present embodiment, the blocking member 1003 is rotatably connected to the housing 10 so as to be openable relative to the housing 10. When the blocking member 1003 covers the opening 11, the blocking member 1003 is closed on the body 1001, and the blocking member 1003, the housing 10 and the workbench 20 together enclose a processing space. When the blocking member 1003 covers the opening 11, the blocking member 1003 is in a closed state. When the blocking member 1003 is not covered on the opening 11, the blocking member 1003 is in an open state. It can be understood that the connection mode between the blocking member 1003 and the housing 10 is not limited to a rotational connection, for example, the blocking member 1003 is slidably connected to the housing 10.

[0052] It can be understood that the workbench 20 and the track device 30 can be omitted, and the workpiece is carried on a carrying surface (such as a desktop or the ground), the housing 10 is placed on the carrying surface, the housing 10 and the blocking member 1003 together enclose a processing space, and the laser processing device 40 is used to perform laser processing on the workpiece.

[0053] The first sensor 1004 is disposed on the housing 10 of the body 1001. In this embodiment, the first sensor 1004 is a Hall sensor, and the first sensor 1004 is disposed on the housing 10. In other embodiments of the present application, the first sensor 1004 may also be a photoelectric sensor, etc. The first sensor 1004 is used to automatically monitor the state of the body 1001, thereby improving the automation and intelligence of the laser processing equipment 100.

[0054] See also Figure 3 and Figure 4 The locking unit 1005 is provided on at least one of the machine body 1001 and the blocking member 1003, and the locking unit 1005 includes a locked state, an unlocked state, and an abnormal state. When the blocking member 1003 is in the closed state and the locking unit 1005 is in the locked state, the blocking member 1003 is locked on the machine body 1001 by the locking unit 1005, that is, the blocking member 1003 remains closed on the machine body 1001.

[0055] When the locking unit 1005 is in the unlocked state, the blocking member 1003 can move relative to the body 1001. For example, through the movement of the blocking member 1003 relative to the body 1001, the blocking member 1003 can be switched from the closed state to the open state, or the blocking member 1003 can be switched from the open state to the closed state.

[0056] The locking unit 1005 is in an abnormal state, which means that the locking unit 1005 is abnormal. The abnormal state of the locking unit 1005 includes two situations: the current value on the locking unit 1005 is not greater than the preset value, and the locking unit 1005 is in an abnormal state; and the current value on the locking unit 1005 is greater than the preset value, and the locking unit 1005 is in an abnormal state. When the current value on the locking unit 1005 is not greater than the preset value and the locking unit 1005 is in an abnormal state, the locking unit 1005 cannot be switched to the locked state (i.e., locked) when it is in the unlocked state, and / or the locking unit 1005 cannot be switched to the unlocked state when it is in the locked state.

[0057] When the current value on the locking unit 1005 is not greater than the preset value, the locking unit 1005 is in an abnormal state, the hardware of the locking unit 1005 is not damaged, and the locking unit 1005 can be adjusted to restore the opening and closing operation. When the current value on the locking unit 1005 is greater than the preset value, it means that the hardware of the locking unit 1005 is damaged, and the locking unit 1005 can be automatically switched to the unlocking state by cutting off the power to the locking unit 1005.

[0058] Please refer to Figure 5 , Figure 6 and Figure 7The locking unit 1005 includes a first locking portion 131 and a second locking portion 132 that can move relative to each other. The first locking portion 131 is arranged on the body 1001, and the second locking portion 132 is arranged on the blocking member 1003. The position where the first locking portion 131 moves relative to the second locking portion 132 includes an unlocking position and a locking position. When the first locking portion 131 moves relative to the second locking portion 132 to the unlocking position, the locking unit 1005 is in an unlocking state. When the first locking portion 131 moves relative to the second locking portion 132 to the locking position, the locking unit 1005 is in a locking state. If the first locking portion 131 cannot move from the unlocking position to the locking position, the locking unit 1005 is in an abnormal state. If the first locking portion 131 cannot move from the locking position to the unlocking position, the locking unit 1005 is in an abnormal state.

[0059] In this embodiment, the first locking portion 131 includes a driving body 1311, a telescopic rod 1312 and a mounting seat 1313. The second locking portion 132 includes a locking hole 1321 provided on the blocking member 1003. The mounting seat 1313 is fixed to a position of the door frame bracket 111 close to the blocking member 1003, the driving body 1311 is fixed to the mounting seat 1313, the telescopic rod 1312 is movably provided on the mounting seat 1313, and the telescopic rod 1312 can penetrate the locking hole 1321, so that the first locking portion 131 is locked and connected with the second locking portion 132. The driving body 1311 is used to drive the telescopic rod 1312 to move toward the locking hole 1321 or toward a direction away from the locking hole 1321, so that the locking unit 1005 switches between a locked state and an unlocked state. When the telescopic rod 1312 at least partially penetrates the locking hole 1321, the first locking portion 131 is located at a locked position relative to the second locking portion 132, and the locking unit 1005 is in a locked state. When the telescopic rod 1312 is disengaged from the locking hole 1321, the locking unit 1005 is in an unlocked state. When the locking unit 1005 is in the locked state, the telescopic rod 1312 is at least partially penetrated into the locking hole 1321, and the locking hole 1321 limits the telescopic rod 1312, reducing the possibility of the telescopic rod 1312 disengaging from the blocking member 1003.

[0060] The second sensor 1006 is used to sense the state of the locking unit 1005. In this embodiment, the second sensor 1006 is arranged adjacent to the locking unit. Specifically, the second sensor 1006 is a limit switch, which is a commonly used low-current master electrical appliance that uses the collision of the moving parts of the production machinery to make its contacts move to connect or disconnect the control circuit. In this embodiment, the limit switch is arranged below one of the ends of the telescopic rod 1312. It can be understood that when the locking unit 1005 is in the unlocked state, the end of the telescopic rod 1312 squeezes the limit switch to close the limit switch. When the laser processing equipment receives the closing signal of the limit switch, it can be confirmed that the locking unit 1005 is in the unlocked state; when the locking unit 1005 is in the locked state, the end of the telescopic rod 1312 is separated from the limit switch to disconnect the limit switch. When the laser processing equipment receives the disconnection signal of the limit switch, it can be confirmed that the locking unit 1005 is in the locked state. It is understood that in some possible embodiments of the present application, the second sensor 1006 includes but is not limited to a photoelectric switch, a proximity switch, a Hall switch, etc., and the present application does not limit this. In some other embodiments, the second sensor 1006 can be omitted.

[0061] Please refer again Figure 1 The control system 1009 is used to support the laser processing equipment 100 to implement the control method provided in the embodiment of the present application. The control system 1009 is arranged on the body 1001. For example, the control system 1009 is arranged integrally with the workbench 20. Alternatively, the control system 1009 and the body 1001 can be arranged separately, and the control system 1009 and the body 1001 support wired or wireless communication. The first sensor 1004, the locking unit 1005, and the second sensor 1006 communicate with the control system 1009 through wired or wireless communication.

[0062] The control system 1009 can be implemented in the form of a terminal device and / or a server, etc. The terminal device here can be, for example, a mobile phone, a computer, a tablet computer, etc. The server can be a cloud server, etc.

[0063] The control system 1009 includes a processor 101, a memory 103, an interface circuit 105, an interaction unit 107 and a reminder device 109. It can be understood that the present application includes at least one component of the processor 101, the memory 103, the interface circuit 105, and the interaction unit 107. The processor 101 is mainly used to implement the processing operations provided by the implementation method of the present application, such as controlling the control system 1009, executing software programs, processing data of software programs, etc. The memory 103 is mainly used to store software programs and data. The interface circuit 105 can be used to support the communication of the laser processing equipment 100. The interface circuit 105 may include a transceiver or an input and output interface. The interaction unit 107 can be used to support human-computer interaction.

[0064] It should be understood that for ease of explanation, Figure 1 Only one memory 103 and processor 101 are shown. In the actual control system 1009, there may be one or more processors 101 and one or more memories 103. The memory 103 may also be referred to as a computer storage medium or storage device, etc. The memory 103 may be set independently of the processor 101, or may be integrated with the processor 101, and the embodiments of the present application do not limit this.

[0065] Please refer again Figure 2 The interaction unit 107 is used to realize the input and output interaction between the control system 1009 and the user, and the specific form is related to the interaction method. For example, the interaction unit 107 includes a key switch 1071, and the key switch 1071 is arranged on the housing 10 of the body 1001, and is used for the user to trigger the processing instruction, and the processing instruction includes the start processing instruction, the pause processing instruction, the stop processing instruction, the continue processing instruction, etc. The processing instruction can be triggered when the user presses the key switch 1071. The number of key switches 1071 can be multiple, so that the user can trigger different processing instructions. It can be understood that the key switch 1071 can also be one, which can realize the triggering of various processing instructions.

[0066] The process status of a processing task includes pause status, stop status, completion status and continue status.

[0067] When the start processing instruction is triggered, the control system 1009 can control the machine body 1001 to start executing the processing task.

[0068] During the process of the machine body 1001 executing the processing task, if the pause processing instruction is triggered, the control system 1009 can control the machine body 1001 to pause the execution of the processing task, and the process status of the processing task is a paused state.

[0069] During the process of the machine body 1001 executing the processing task, if the stop processing instruction is triggered, the control system 1009 can control the machine body 1001 to stop executing the processing task, and the process status of the processing task is the stop status.

[0070] If the machine body 1001 completes the execution of the processing task, the process status of the processing task is the completion status.

[0071] When the process state of the processing task is in the pause state, if the continue processing instruction is triggered, the control system 1009 can control the machine body 1001 to continue executing the processing task, and the control system 1009 can control the process state of the processing task to switch from the pause state to the continue state.

[0072] The interaction unit 107 may also include a touch screen 1075, and the user can achieve input and output interaction with the user by touching the touch screen 1075. If the interaction is achieved through air gesture recognition, the interaction unit 107 may include a camera, a millimeter wave radar or an ultrasonic sensor, etc. If it is achieved through semantic recognition, the interaction unit 107 may include a microphone and a speaker. Of course, it is also possible that the input and output are mixed, such as input through a microphone and output through a touch screen. There may also be a combination of multiple input and output methods, for example, the input method includes a combination of touch gestures and air gestures, and / or the output method includes a variety of methods such as displaying and playing voice, sound or music through a display screen, which are not specifically limited in this application.

[0073] It is understandable that the interactive unit 107 can omit the key switch 1071, and the user can trigger various processing instructions through the touch display screen 1075. For example, multiple processing instruction virtual keys are displayed on the virtual control interface of the touch display screen 1075, and when the user touches one of the virtual keys, the corresponding processing instruction is triggered. In addition, the touch display screen 1075 can output a warning message to remind the user.

[0074] It is understandable that the interactive unit 107 can omit the touch display screen 1075.

[0075] The reminder device 109 is used to output warning information to remind the user that the laser processing equipment 100 is abnormal. In this embodiment, the reminder device 109 may include a warning light, and the warning information includes a warning light, for example, a red warning light. When the locking unit 1005 is in an abnormal state, the reminder device 109 emits a warning light. It can be understood that the reminder device 109 can also include a buzzer, and the warning information can include a warning sound, for example, a buzzer; the reminder device 109 can also include a display screen, for example, the warning information can also include image information and / or text symbol information, etc. This application does not limit the reminder device and its warning information. It can be understood that the reminder device 109 can be omitted, and the warning information is output through the touch display screen 1075.

[0076] The processor 101 is used to send a processing task execution request to the machine body 1001 so that the laser processing device 100 starts the laser processing process. In this embodiment, the processor 101 sends a processing task execution request to the machine body 1001 by sending a Gcode file to the machine body 1001, and the laser processing device 100 starts the laser processing process.

[0077] The processor 101 is also used to send a lock instruction to the locking unit 1005 to control the locking unit 1005 to switch from the unlocked state to the locked state (i.e., locked). The processor 101 is also used to send an unlock instruction to the locking unit 1005 to control the locking unit 1005 to switch from the locked state to the unlocked state (i.e., unlocked).

[0078] The processor 101 is further configured to control the locking unit 1005 to be in an unlocked state or a locked state according to the state of the blocking member 1003 and / or the progress state of the processing task detected by the first sensor 1004 .

[0079] In this embodiment, the processor 101 is also used to control the locking unit 1005 to be in an unlocked state or a locked state according to the state of the blocking member 1003 detected by the first sensor 1004, including: if the state of the blocking member 1003 is a closed state, controlling the locking unit 1005 to be in a locked state.

[0080] In this embodiment, according to the first sensor 1004 sensing that the blocking member 1003 is in the closed state, the processor 101 sends a locking instruction to the locking unit 1005 to control the locking unit 1005 to switch from the unlocked state to the locked state.

[0081] When the laser processing device 100 needs to perform laser processing, the blocking member 1003 is closed on the body 1001. When the first sensor 1004 senses that the body 1001 is in a closed state, the processor 101 sends a locking instruction to the locking unit 1005 to keep the blocking member 1003 closed on the body 1001. Since the blocking member 1003 is locked on the body 1001 by the locking unit 1005, the blocking member 1003 is prevented from being opened by the user during the laser processing of the laser processing device 100, thereby preventing the laser from overflowing from the processing space. In this way, the risk of users around the laser processing device 100 being injured by the laser is reduced, and the processing safety of the laser processing device 100 is further improved.

[0082] In this embodiment, the processor 101 is also used to control the locking unit 1005 to be in an unlocked state or a locked state according to the process status of the processing task, including: if the process status of the processing task is any one of the paused state, the stopped state and the completed state, the locking unit 1005 is controlled to be in an unlocked state.

[0083] In this embodiment, the processor 101 is also used to control the locking unit 1005 to be in an unlocked state or a locked state according to the state of the blocking member 1003 and the progress state of the processing task detected by the first sensor 1004, including: if the state of the blocking member 1003 is a closed state and the progress state of the processing task is a continuing state, the locking unit 1005 is controlled to be in a locked state.

[0084] In this embodiment, after controlling the locking unit 1005 to be in a locked state, the processor 101 is also used to control the second sensor 1006 to detect the state of the locking unit 1005; if the locking unit 1005 is in a locked state, the control body 1001 performs the processing task; if the locking unit 1005 is in an unlocked state, the control reminder device 109 outputs a warning message.

[0085] The locking unit 1005 is not locked, and the blocking member 1003 is at risk of being easily opened. After the processor 101 sends a locking instruction to the locking unit 1005, that is, when the processor 101 controls the locking unit 1005 to be in a locked state, the locking unit 1005 may fail to be locked due to an abnormality. In this embodiment, when the second sensor 1006 senses that the locking unit 1005 is in a locked state, the body 1001 is controlled to perform the processing task, reducing the possibility that the body 1001 starts to perform the processing task when the locking unit 1005 is not locked, thereby further improving the processing safety of the laser processing equipment 100.

[0086] After the processor 101 controls the locking unit 1005 to be in a locked state, if the locking unit 1005 is in an unlocked state, it means that the locking unit 1005 fails to be locked due to an abnormality. The user is reminded by controlling the reminder device 109 to output a warning message, thereby improving the ease of use of the laser processing equipment 100.

[0087] In this embodiment, the processor 101 is further used to send an unlocking instruction to the locking unit 1005 if the processing task of the machine body 1001 is completed, so as to control the locking unit 1005 to switch from the locked state to the unlocked state. When the processing task of the machine body 1001 is completed, the process state of the processing task is the completed state, and the locking unit 1005 automatically switches from the locked state to the unlocked state, thereby improving the automation degree of the laser processing equipment 100.

[0088] In this embodiment, the processor 101 is also used to detect the current value of the locking unit 1005. If the current value of the locking unit 1005 is greater than a preset value, the reminder device 109 is controlled to output a warning message. By detecting the current value of the locking unit 1005, the use of the locking unit 1005 is monitored. When the locking unit 1005 is abnormal, the reminder device 109 outputs a warning message to remind the user, thereby improving the convenience of use of the laser processing equipment 100.

[0089] A control method of a laser processing device 100 provided in this embodiment is described below. The control method can be executed by the processor 101.

[0090] See also Figure 8 , a control method of a laser processing device 100 comprises the following steps:

[0091] Step S101 , according to the state of the blocking member 1003 detected by the first sensor 1004 , the locking unit 1005 is controlled to be in an unlocked state or a locked state.

[0092] The processor 101 may send a lock instruction to the locking unit 1005 to control the locking unit 1005 to switch from the unlocked state to the locked state (i.e., locked). The processor 101 may send an unlock instruction to the locking unit 1005 to control the locking unit 1005 to switch from the locked state to the unlocked state (i.e., unlocked).

[0093] According to the state of the blocking member 1003 detected by the first sensor 1004, the locking unit 1005 is controlled to be in an unlocked state or a locked state, including: if the state of the blocking member 1003 is a closed state, the locking unit 1005 is controlled to be in a locked state.

[0094] The first sensor 1004 automatically senses that the blocking member 1003 is in a closed state, and controls the locking unit 1005 to be in a locked state, thereby achieving precise control and avoiding the situation where the user mistakenly judges that the blocking member 1003 is closed when it is actually open, thereby improving the safety of laser processing.

[0095] Step S102 , controlling the second sensor 1006 to detect the state of the locking unit 1005 .

[0096] Step S103, after controlling the locking unit 1005 to be in the locked state, if the locking unit 1005 is in the locked state, the control body 1001 executes the processing task.

[0097] If the second sensor 1006 detects that the first locking portion 131 of the locking unit 1005 reaches the locked position, the locking unit 1005 is in the locked state, and the processor 101 controls the body 1001 to execute the processing task.

[0098] When the locking unit 1005 is not locked, there is a risk that the blocking member 1003 may be easily opened. Only after the second sensor 1006 senses that the locking unit 1005 is in a locked state, the body 1001 is controlled to execute the processing task, thereby reducing the possibility that the body 1001 starts to execute the processing task when the locking unit 1005 is not locked, thereby further improving the safety of laser processing.

[0099] Step S104, after controlling the locking unit to be in the locked state, if the locking unit 1005 is in the unlocked state, controlling the reminder device 109 to output a warning message.

[0100] After the locking unit 1005 receives the locking instruction, the first locking portion 131 does not move to the locking position. If the second sensor 1006 detects that the first locking portion 131 of the locking unit 1005 has not reached the unlocking position, that is, the locking unit 1005 is abnormal and still in the unlocking state, the control reminder device 109 outputs a warning message.

[0101] Step S105 , detecting the current value of the locking unit 1005 , if the current value of the locking unit 1005 is greater than a preset value, controlling the reminder device 109 to output a warning message.

[0102] The current value of the locking unit 1005 is greater than the preset value, the hardware structure of the locking unit 1005 is damaged and cannot be unlocked or locked, and the locking unit 1005 is abnormal. Step S105 can be performed simultaneously with steps S101-S104.

[0103] After the locking unit 1005 is controlled to be in the locked state, if the current value of the locking unit 1005 is greater than the preset value, it means that the locking unit 1005 is abnormal, and the reminder device 109 outputs a warning message to remind the user that the locking unit 1005 is abnormal.

[0104] It can be understood that steps S102-S105 can be omitted.

[0105] Another embodiment of the present application provides a control method for a laser processing device 100, which can be executed by a processor 101. Fig. 9 , the control method comprises the following steps:

[0106] Step S201, according to the progress status of the processing task, control the locking unit 1005 to be in an unlocked state or a locked state.

[0107] The state of the locking unit 1005 is controlled by the progress state of the processing task instead of using a sensor sensing method, which is beneficial to simplifying the structure of the laser processing equipment 100.

[0108] According to the process status of the processing task, the locking unit 1005 is controlled to be in an unlocked state or a locked state, that is, step S201, including: if the process status of the processing task is any one of the paused state, the stopped state and the completed state, the locking unit 1005 is controlled to be in an unlocked state.

[0109] When the machine body 1001 is executing a processing task, the locking unit 1005 is in a locked state.

[0110] If the processing pause instruction is triggered during the process of the machine body 1001 executing the processing task, the processor 101 controls the machine body 1001 to pause the processing task, and the process state of the processing task is the pause state. After the processing pause instruction is triggered, the locking unit 1005 is controlled to switch from the locked state to the unlocked state. The processor 101 can send an unlock instruction to the locking unit 1005 to control the locking unit 1005 to switch from the locked state to the unlocked state.

[0111] If the stop processing instruction is triggered during the process of the machine body 1001 executing the processing task, the processor 101 controls the machine body 1001 to stop executing the processing task, the process state of the processing task is the stop state, and controls the locking unit 1005 to switch from the locked state to the unlocked state.

[0112] If the machine body 1001 completes the processing task, the process status of the processing task is in the completed state, and the locking unit 1005 is controlled to switch from the locked state to the unlocked state.

[0113] According to the state of the blocking member 1003 detected by the first sensor 1004, the locking unit 1005 is controlled to be in an unlocked state or a locked state, that is, S201, including: if the state of the blocking member 1003 is a closed state and the progress state of the processing task is a continuing state, the locking unit 1005 is controlled to be in a locked state.

[0114] If the state of the blocking member 1003 is the closed state and the process state of the processing task is the continued state, the locking unit 1005 is controlled to be in the locked state, including the steps of:

[0115] S2011, when the blocking member 1003 is in the closed state, the locking unit 1005 is in the unlocked state, and the processing process is in the paused state, the process state of the processing task is controlled to be the continued state;

[0116] S2012, control the locking unit 1005 to be in a locked state.

[0117] Step S202 , controlling the second sensor 1006 to detect the state of the locking unit 1005 .

[0118] Step S203, after controlling the locking unit 1005 to be in the locked state, if the locking unit 1005 is in the locked state, the control body 1001 executes the processing task.

[0119] If the second sensor 1006 detects that the first locking portion 131 of the locking unit 1005 reaches the locked position, the locking unit 1005 is in the locked state, and the processor 101 controls the body 1001 to execute the processing task.

[0120] Step S204, after controlling the locking unit 1005 to be in the locked state, if the locking unit 1005 is in the unlocked state, controlling the reminder device 109 to output a warning message.

[0121] After the locking unit 1005 receives the locking instruction, the first locking portion 131 does not move to the locking position. If the second sensor 1006 detects that the first locking portion 131 of the locking unit 1005 has not reached the unlocking position, that is, the locking unit 1005 is abnormal and still in the unlocking state, the control reminder device 109 outputs a warning message.

[0122] Step S205 , detecting the current value of the locking unit 1005 , if the current value of the locking unit 1005 is greater than a preset value, controlling the reminder device 109 to output a warning message.

[0123] The current value of the locking unit 1005 is greater than the preset value, the hardware structure of the locking unit 1005 is damaged and cannot be unlocked or locked, and the locking unit 1005 is abnormal.

[0124] It can be understood that S202-S205 can be omitted.

[0125] See also Fig.10 Another embodiment of the present application provides a control method applied to the above-mentioned laser processing equipment 100, comprising the following steps:

[0126] Step S301 , sending a request to execute a processing task to the machine body 1001 , and starting the laser processing flow of the laser processing equipment 100 .

[0127] Step S303, judging whether the blocking member 1003 is in a closed state according to the state of the machine body 1001 sensed by the first sensor 1004. In this embodiment, if the answer is yes (Y), that is, it is determined that the blocking member 1003 is in a closed state, then step S305 is performed. If the answer is no (N), that is, it is determined that the blocking member 1003 is in an open state, the process returns to step S301, and the laser processing device 100 restarts the laser processing process.

[0128] It can be understood that in other embodiments of the present application, when it is determined that the blocking member 1003 is in an open or closed state, step S303 can be repeated.

[0129] It can be understood that in other embodiments of the present application, after step S303 and before step S305 , the control method may further include a step of controlling the reminder device 109 to output a warning message to remind the user that the blocking member 1003 is not closed on the body 1001 .

[0130] Step S305, determining whether the interactive unit 107 is triggered to start the processing instruction. If yes (Y), it is determined that the interactive unit 107 is triggered to start the processing instruction, and then step S307 is performed. If no (N), it is determined that the interactive unit 107 is not triggered to start the processing instruction, and the process returns to step S301, and the laser processing equipment 100 restarts the laser processing process.

[0131] In this embodiment, it is determined whether the interaction unit 107 is triggered to start the processing instruction within a preset time. For example, it is determined whether the key switch 1071 is pressed within a preset time. If it is pressed, it is regarded as triggering the start processing instruction.

[0132] It can be understood that in other embodiments of the present application, when it is determined that the interaction unit 107 is not triggered to start the processing instruction, the process may return to step S303.

[0133] Step S307 , sending a locking instruction to the locking unit 1005 to control the locking unit 1005 to switch from the unlocked state to the locked state, so that the blocking member 1003 remains closed on the body 1001 .

[0134] Step S307 also includes controlling the laser processing device 40 to move from the original position to the preset processing position.

[0135] Step S309, judging whether the locking unit 1005 is in a locked state according to the state of the locking unit 1005 sensed by the second sensor 1006. If yes (Y), it is determined that the locking unit 1005 is in a locked state, and then proceeding to step S311. If no (N), it is determined that the locking unit 1005 is in an abnormal state, and then proceeding to step S327.

[0136] In this embodiment, if the second sensor 1006 senses that the first locking portion 131 has not reached the locked position, the second sensor 1006 senses that the locking unit 1005 is in an abnormal state. Based on the second sensor 1006 sensing that the locking unit 1005 is in an abnormal state, it is determined that the locking unit 1005 is in an abnormal state.

[0137] Step S311, controlling the machine body 1001 to start executing the processing task. The machine body 1001 starts executing the processing task including: the laser processing device 40 emits laser to perform laser processing on the workpiece.

[0138] Step S313, determine whether the interactive unit 107 is triggered to suspend the processing instruction. If it is Y, execute step S319. If it is Y, the process state of the processing task is suspended, the current processing task of the machine body 1001 is terminated, and the machine body 1001 suspends the processing task. Controlling the machine body 1001 to suspend the processing task includes controlling the laser processing device 40 to stop emitting laser. After a period of time after the machine body 1001 is suspended, the machine body 1001 can resume the current processing task.

[0139] In this embodiment, when the machine body 1001 is executing a processing task, if the key switch 1071 is pressed briefly, it is determined that the interaction unit 107 is triggered to suspend the processing instruction.

[0140] It can be understood that after the machine body 1001 is paused for a preset period of time, and the blocking member 1003 is in a closed state and the locking unit 1005 is in a locked state, step S315 can be executed, that is, the machine body 1001 automatically resumes (continues) to execute the current processing task, and the process status of the processing task is automatically switched from a paused state to a continued state.

[0141] It can be understood that after the machine body 1001 is suspended for a period of time while executing a processing task, the blocking member 1003 is in a closed state, and the locking unit 1005 is in a locked state, if the continuing processing instruction of the interactive unit 107 is triggered, the process state of the processing task is switched from a paused state to a continued state, and the machine body 1001 can continue to execute the suspended processing task.

[0142] Step S315, determining whether the interactive unit 107 is triggered to stop the processing instruction. If yes (Y), executing step S319. If no (N), executing step S317.

[0143] In this embodiment, when the machine body 1001 is executing a processing task, if the key switch 1071 is long pressed, it is determined that the interactive unit 107 is triggered to stop the processing instruction, and the process state of the processing task is stopped. The process state of the processing task is stopped, which means that the laser processing device 100 ends the current laser processing process. The long-pressing time of the key switch 1071 is greater than the short-pressing time of the key switch 1071.

[0144] It can be understood that when the process status of the processing task is stopped, the blocking member 1003 is in a closed state, and the locking unit 1005 is in a locked state, if the continue processing instruction of the interactive unit 107 is triggered, the machine body 1001 can be controlled to continue to execute a new round of processing tasks.

[0145] Step S317, determine whether the current processing task of the machine body 1001 is completed, if yes (Y), execute step S319. If no (N), return to step S301.

[0146] In other implementations of the present application, if the answer is no (N), the process may return to one of steps S311, S313, and S315.

[0147] Step S319: sending an unlocking instruction to the locking unit 1005 to control the locking unit 1005 to switch from the locked state to the unlocked state (ie, unlocking). After the locking unit 1005 switches to the unlocked state, the blocking member 1003 can be opened relative to the body 1001.

[0148] Step S321, judging whether the locking unit 1005 is in an unlocked state according to the state of the locking unit 1005 sensed by the second sensor 1006. If yes (Y), executing step S323. If no (N), i.e. determining that the locking unit 1005 is in an abnormal state, executing step S325.

[0149] If the second sensor 1006 senses that the first locking portion 131 has reached the unlocking position (i.e., it is determined to be Y), the locking unit 1005 is determined to be in the unlocking state, and step S323 is performed. If the second sensor 1006 senses that the first locking portion 131 has not reached the unlocking position (i.e., it is determined to be N), the locking unit 1005 is determined to be in an abnormal state, and step S327 is performed.

[0150] Step S323, determine whether to continue processing. In this embodiment, determine whether the interaction unit 107 is triggered to continue processing. If yes (Y), return to step S301, otherwise execute step S327. It can be understood that in other embodiments of the present application, it is determined to continue processing according to the process status of the processing task being the completed state.

[0151] Step S325, controlling the reminder device 109 to output a warning message.

[0152] Step S327, ending the laser processing process.

[0153] It can be understood that the above steps are not limited to being performed in sequence, and the order of some steps can be performed simultaneously or swapped, for example, the order of steps S313 and S315 can be swapped, and some steps can be omitted, for example, steps S313, S315, and S323 can be omitted.

[0154] Another embodiment of the present application provides a control method for a laser processing device 100, which can be executed by a processor 101. The control method includes: controlling the locking unit to be in an unlocked state or a locked state according to the state of the blocking member detected by the first sensor and / or the progress state of the processing task.

[0155] Wherein, controlling the locking unit to be in an unlocked state or a locked state according to the state of the blocking member detected by the first sensor includes: if the state of the blocking member is a closed state, controlling the locking unit to be in a locked state.

[0156] Among them, according to the process status of the processing task, controlling the locking unit to be in an unlocked state or a locked state includes: if the process status of the processing task is any one of a paused state, a stopped state and a completed state, controlling the locking unit to be in an unlocked state.

[0157] Among them, according to the state of the blocking member detected by the first sensor and the progress state of the processing task, controlling the locking unit to be in an unlocked state or a locked state includes: if the state of the blocking member is a closed state and the progress state of the processing task is a continuing state, controlling the locking unit to be in a locked state.

[0158] Among them, after controlling the locking unit to be in a locked state, the control method also includes: controlling the second sensor to detect the state of the locking unit; if the locking unit is in a locked state, controlling the body to execute the processing task; if the locking unit is in an unlocked state, controlling the reminder device to output a warning message.

[0159] The control method further includes: detecting the current value of the locking unit, and if the current value of the locking unit is greater than a preset value, controlling the reminder device to output a warning message.

[0160] Through the control method of the present application, the state of the blocking member and / or the progress state of the processing task are detected by the first sensor to control the locking unit. On the one hand, when the laser processing equipment is processing, the blocking member is always in a closed state by controlling the locking unit to be in a locked state, preventing the user from opening the blocking member during the process and causing the laser to overflow and affect their own safety; on the other hand, according to the corresponding task progress state, while ensuring that the laser does not overflow, the machine can automatically control the locking unit to be in an unlocked state, thereby improving the convenience of interaction between the user and the device. In addition, in the control method of the present application, the state of the locking unit is also detected in real time according to the second sensor, and the user can be reminded in time when an abnormality occurs in the locking unit, further improving the safety of the laser processing equipment, thereby further ensuring the safety of the user.

[0161] An embodiment of the present application provides a computer-readable storage medium, wherein the storage medium stores at least one program instruction or code, and when the program instruction or code is loaded and executed by a processor, the computer implements the control method as described above.

[0162] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
