Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a laser processing machine cover and laser processing equipment. Background Art

[0002] Laser processing machines typically focus laser light emitted from a laser source into a high-power, high-density beam through an optical system. The laser beam strikes the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the melted or vaporized material. However, the laser processing process generates arc light, smoke, and other waste gases and waste, which can be harmful to the human body. Therefore, adding a shield to the laser processing machine's beam can significantly reduce these hazards.

[0003] At present, there are some laser processing machine covers. The laser processing machine covers are irradiated outside the laser processing machine. The laser processing machine beam is connected to the bracket inside the laser processing machine cover and can move with the movement of the beam. However, the laser processing machine cover is semi-closed, that is, the front, back, left, right and top of the laser processing cover are closed but the bottom is open. The smoke and dust waste after processing will diffuse near the workpiece and inside the laser processing cover. The smoke and dust waste diffused near the workpiece blocks the workpiece and affects the processing; part of the smoke and dust waste located in the laser processing cover will be discharged through the opening at the bottom of the laser processing machine cover and diffused in the environment, causing harm to people in the environment; the remaining smoke and dust waste will accumulate in the laser processing machine cover. When the user wants to open the cover for subsequent work, he will directly contact the smoke and dust waste accumulated in the laser processing machine cover, causing harm to the user.

[0004] Therefore, there is an urgent need for a laser processing machine cover that can effectively remove smoke and dust waste that is diffused near the workpiece and inside the laser processing cover while being able to move with the crossbeam. Utility Model Content

[0036] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the drawings only show portions relevant to the present invention, not all of them.

[0038] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] This embodiment provides a laser processing device for processing materials. The laser processing device includes a laser processing unit, a beam, a guide rail, and a laser processing unit cover. The laser processing unit is mounted on the beam, and the beam and the guide rail are slidably connected, allowing the laser processing unit to follow the movement of the beam on the guide rail. When the laser processing unit reaches a working position, it processes the material.

[0042] Laser processing machines are generally completely exposed to the external environment, but during the laser processing process, the strong light and smoke generated are very harmful to the human body. Therefore, adding a laser processing machine cover to the laser processing machine can greatly reduce such hazards. In this embodiment, the crossbeam is connected to the laser processing machine cover, and the laser processing machine is slidably connected to the guide rail to effectively protect the operator. Although the laser processing machine cover can block the strong light and smoke generated by laser processing from the operator, the smoke and dust waste will accumulate at the working position of the laser processing machine and diffuse in the laser processing machine cover. When the smoke and dust waste accumulated in the laser processing machine cover and the laser processing machine working position exceeds its carrying capacity, the smoke and dust waste will diffuse in the environment outside the laser processing machine cover in various ways, causing damage to people in the environment.

[0043] To solve the above problems, Figure 1-4 As shown, the laser processing machine cover provided in this embodiment includes a protective cover 1, a blowing assembly 2, and a suction assembly 3. The protective cover 1 is positioned outside the laser processing machine and the crossbeam. It is used to block the smoke, dust, and strong light generated by the laser processing machine to protect the operator from the strong light and smoke. At the same time, the protective cover 1 is connected to the crossbeam, allowing it to move with the laser processing machine, reducing the occupied volume of the laser processing machine cover and more accurately blocking the smoke, dust, and strong light. The blowing assembly 2 is connected to the protective cover 1, with the blowing port of the blowing assembly 2 facing the laser processing machine. The suction assembly 3 is connected to the protective cover 1 and can exhaust smoke and dust that permeates the protective cover 1 and the laser processing machine workstation. When both the blowing assembly 2 and the suction assembly 3 are in operation, the blowing assembly 2 blows away the smoke and dust near the laser processing machine to prevent it from affecting processing, while the suction assembly 3 discharges the smoke and dust that is blown away by the blowing assembly 2. The above settings not only block the strong light and smoke waste generated when the laser processing machine processes materials, but also clean the smoke waste diffused in the laser processing machine work station and the laser processing machine cover, thereby avoiding the situation when the smoke waste accumulated in the laser processing machine cover and the laser processing machine work station exceeds their carrying capacity. The smoke waste will diffuse into the environment outside the laser processing machine cover in various ways and cause harm to people in the environment.

[0044] Specifically, if Figure 1As shown, in order to facilitate the operation of the laser processing machine, the protective cover 1 is set as a cover structure with an open bottom to avoid interference between the protective cover 1 and the beam, guide rail or laser processing machine, thereby ensuring smooth operation of the laser processing machine.

[0045] To ensure that the smoke and dust waste diffused on the working position of the laser processing machine can be cleaned up, the suction component 3 includes a first suction component 3a, which is connected to the bottom end of the protective cover 1. The first suction component 3a is close to the working position of the laser processing machine in a straight line, so that the first suction component 3a can better clean the smoke and dust diffused on the working position of the laser processing machine.

[0046] It is understandable that smoke and dust waste are generated at the working position of the laser processing machine. By setting the first suction component 3a close to the laser processing machine, most of the smoke and dust generated when the laser processing machine is working can be directly discharged outside the protective cover 1 to prevent the smoke and dust from spreading to other locations; the bottom end of the protective cover 1 is an open structure, and the first suction component 3a is directly set at the bottom end of the protective cover 1. There is no need to open the protective cover 1 to discharge smoke and dust, which is conducive to simplifying the structure of the protective cover 1 and improving the strength of the protective cover 1.

[0047] More specifically, if Figure 1 As shown, in this embodiment, the first air suction assembly 3a includes a ventilation duct and an air suction member. The ventilation duct is connected to the bottom end of the protective cover 1. One end of the ventilation duct is located below the protective cover 1, and the other end of the ventilation duct extends outside the protective cover 1. The air suction member is connected to the ventilation duct and is used to drive the airflow in the ventilation duct to flow out of the protective cover 1. The air suction member draws smoke and dust waste through the ventilation duct and out of the protective cover 1. This enhances the protective function of the laser processing machine cover for the operator and further prevents the smoke and dust waste generated by the laser processing machine from affecting the operator.

[0048] Optionally, to ensure effective suction, the ventilation duct can be a spiral tube type ventilation duct or a grille type suction duct. To better protect the suction member, in this embodiment, the ventilation duct is a rectangular, double-sided, interconnected duct. A grille is provided near the side opening of the laser processing machine. This grille not only provides suction but also prevents waste of larger volume or diameter from flowing into the ventilation duct and contacting the suction member, thereby damaging the suction member.

[0049] Optionally, to ensure the suction strength of the suction member, the suction member can be a suction fan, etc. In this embodiment, the suction member is a suction fan. The suction strength of the suction fan is relatively large, and it can better clean up the smoke and dust waste attached to the material to be processed and difficult to clean up by low-intensity suction equipment.

[0050] More specifically, in order to ensure that the smoke and dust waste sucked into the ventilation pipe does not diffuse back into the working position of the laser processing machine and the cover of the laser processing machine, and also to ensure that the smoke and dust waste in the ventilation pipe does not spread to the environment of the laser processing machine cover, in this embodiment, a smoke exhaust port is provided on the first suction component 3a, and the smoke exhaust port is used to be connected to the waste processor so that the smoke and dust can flow directly to the dust collection device to prevent the smoke and dust waste from diffusing to other places.

[0051] Alternatively, as Figure 1 As shown, to better improve the ability to collect dust and waste, in this embodiment, the blowing assembly 2 is also arranged at the bottom end of the protective cover 1 and is arranged opposite the first suction assembly 3a. This arrangement places the blowing assembly 2 close to the working position of the laser processing machine, thereby more efficiently blowing dust and waste to a designated location. In addition, the blowing assembly 2 is arranged opposite the first suction assembly 3a. When both the blowing assembly 2 and the suction assembly 3 are in operation, the blowing assembly 2 blows the dust and waste close to the suction assembly 3, and the suction assembly 3 discharges the dust and waste blown by the blowing assembly 2 outward. This can specifically collect dust and waste on the laser processing machine working position between the two, achieving the ability to efficiently collect dust and waste.

[0052] When the laser processing machine is working, the smoke and dust waste generated not only permeates the working position of the laser processing machine, but also permeates the cover of the laser processing machine. Part of the smoke and dust waste accumulates in the cover of the laser processing machine. When the user wants to open the cover for subsequent work, he will directly contact the smoke and dust waste accumulated in the cover of the laser processing machine, causing harm to the user. In addition, the smoke and dust waste accumulated in the cover of the laser processing machine is discharged through the opening at the bottom of the cover of the laser processing machine and permeates the environment, causing harm to people in the environment. In order to solve the above problems. Specifically, Figure 1-3 As shown, in this embodiment, an exhaust port 111 is provided on the protective cover 1, and the suction component 3 includes a second suction component 3b, which is connected to the exhaust port 111. The smoke and dust waste diffused in the cover of the laser processing machine can be sucked through the second suction component 3b and then discharged outside the cover of the laser processing machine through the exhaust hole, thereby achieving the purpose of removing the smoke and dust waste diffused in the cover of the laser processing machine.

[0053] Specifically, in order to prevent the smoke and dust waste discharged from the exhaust port 111 from spreading into the environment where the laser processing equipment is located, in this embodiment, the exhaust port 111 is connected to the smoke and dust collection device so that the smoke and dust can flow directly to the smoke and dust collection device to prevent the smoke and dust waste from spreading to other places.

[0054] Optionally, in order to make the smoke waste of the laser processing machine discharged from the exhaust port 111, in the embodiment, the exhaust port 111 is arranged in a grid shape, and the smoke waste to be discharged can be filtered once to avoid other impurities being sucked in, so that the smoke collecting device is not damaged. In other embodiments, the exhaust port 111 can have various forms as long as it can meet the requirement that the smoke waste diffused in the cover of the laser processing machine can flow out of the cover of the laser processing machine. For example, the exhaust port 111 can be arranged in a ring shape.

[0055] Optionally, as shown in Figure 1 , a plurality of exhaust ports 111 can be arranged, but the number of the exhaust ports 111 and the second air suction assembly 3b should not be too much or too few. If the exhaust ports 111 are arranged too much, when the second air suction assembly 3b does not work, the exhaust ports 111 are still arranged to discharge the smoke waste outwardly, which pollutes the external environment. If the exhaust ports 111 and the second air suction assembly 3b are arranged too few, the smoke waste cannot be discharged in a short time, and the smoke waste still accumulates in the cover of the laser processing machine, and the arrangement of the exhaust ports 111 and the second air suction assembly 3b is also invalid. Therefore, the number of the exhaust ports 111 is equal and is 2-6. For example, the number of the exhaust ports 111 and the second air suction assembly 3b is equal and is 2, 3, 4, 5 or 6. In order to make the cover of the laser processing machine have better smoke exhaust efficiency, in the embodiment, the exhaust ports 111 are arranged to be 4.

[0056] Optionally, the second air suction assembly 3b can be arranged to be multiple or one; one second air suction assembly 3b can be connected to a plurality of exhaust ports 111, or a plurality of second air suction assemblies 3b can be connected to one exhaust port 111. In the embodiment, the exhaust ports 111 are arranged to be 4, and the exhaust ports 111 and the second air suction assembly 3b are arranged one by one, which can more efficiently use the exhaust ports 111 and the second air suction assembly 3b to discharge the smoke waste in the cover of the laser processing machine, and the one-to-one arrangement of the exhaust ports 111 and the second air suction assembly 3b can also be more convenient for maintenance.

[0057] Specifically, as shown in Figure 1 , the protective cover 1 includes a support 12 and a cover shell, the support 12 is connected with the cross beam, so that the support 12 can move with the cross beam and the laser processing machine, and the cover shell includes a top cover and a side part connected with the axial edge of the top cover, the cover shell is sleeved outside the support 12 and connected with the support 12, so that the cover shell can also move with the cross beam and the laser processing machine, and the arc light and the smoke waste generated during the operation of the laser processing machine are isolated from the operator, thereby protecting the operator.

[0058] Optionally, as Figure 1 As shown, for the convenience of processing, in this embodiment, the protective cover 1 is a rectangular structure. To facilitate the operation of the laser processing machine, the cover shell is a hollow structure at the bottom. In other embodiments, the protective cover 1 can be any shape that can cover the laser processing machine and the beam.

[0059] Specifically, if Figure 2 As shown, in order to ensure that the operator can inspect and repair the laser processing machine more directly and observe the laser processing machine more intuitively at close range, the cover includes a cover body 11 and a door body 112. A door body mounting opening is provided on the front side of the cover body 11 for accommodating the door body 112. The door body 112 is movably connected to the cover body 11 for opening or closing the door body mounting opening.

[0060] Optionally, the movable connection between the door body 112 and the housing body 11 can be a sliding connection or a rotating connection, etc. In this embodiment, Figure 2 As shown, the door body 112 is connected to the cover body 11 through a hinge. A hinge is a connecting piece that allows rotation between two objects. It enables the door to rotate naturally and smoothly around a fixed axis to open and close, thereby realizing the rotational connection between the door body 112 and the cover body 11.

[0061] In order to ensure the safe opening and closing of the door body 112 and the convenient opening and closing of the door body 112, an auxiliary structure for opening and closing the door body 112 is provided on the door body 112 and at a position of the door body 112 corresponding to the cover body 11.

[0062] Optionally, in this embodiment, the auxiliary structure includes an electromagnet, and the door body 112 and the cover body 11 are provided with electromagnets. When the door body 112 closes the door body installation opening, the electromagnet on the door body 112 is provided one-to-one with the electromagnet on the cover body 11 and can be attracted to each other. The electromagnet is connected to the electromagnet control system. The electromagnet is usually in a magnetized state. When the door body 112 is in a closed state and the laser processor and the beam are not working, and the door body 112 needs to be opened, an instruction to open the door can be input to the electromagnet control system. The electromagnet control system controls the demagnetization of the magnets provided on the door body 112 and the cover body 11 to keep the door open to avoid the operator from touching the laser processor when the laser processing machine is working, which may cause safety hazards.

[0063] It should be noted here that the electromagnet control system is an existing structure, and setting a control system in the design of the door body 112 to control the opening and closing of the door body 112 is a conventional setting in this field. In this embodiment, any control system in the existing technology can be used, and any connection method in the existing technology can be used to connect to the electromagnet. As long as the electromagnet control system has the control function of the charging and demagnetization of the electromagnet, it will not be introduced in detail.

[0064] To facilitate the opening and closing of the door 112, optionally, in this embodiment, as Figure 4 As shown, the auxiliary structure includes a door handle, and another door handle is provided on the door body 112. When the operator wants to open the door body 112, he can pull the door handle to drive the door body 112 to open, making it convenient for the operator to open and close the door body 112.

[0065] In order to ensure the integrity of the internal structure of the laser processing machine cover and the service life of the laser processing machine, optionally, in this embodiment, as Figure 4 As shown, the auxiliary structure includes a door lock, which is set on the door body 112. When the door and the door lock are both in the closed state, it is ensured that the laser processing machine cover can be opened when the key holder is not present, and other people cannot perform any operation on the internal structure of the laser processing machine cover, so as to protect the integrity of the internal structure of the laser processing machine cover.

[0066] In other embodiments, the auxiliary device of the door body 112 can be of any structure, as long as it can control or assist the opening and closing of the door body 112. For example, hydraulic devices can also be provided on both the door body 112 and the cover body 11 to control the opening and closing of the door body 112. It should be noted here that the hydraulic device is an existing structure and is a conventional setting in the field in the design of the door body 112. In this embodiment, any hydraulic device in the prior art can be used and connected to the door body 112 and the cover body 11 using any connection method in the prior art. As long as the hydraulic device has the function of controlling the opening and closing of the door body 112, no further detailed introduction will be given.

[0067] Specifically, if Figure 5 As shown, in order to facilitate operators to inspect and repair the electrical box, the cover includes a cover body 11 and an electrical box cover 114. The cover body 11 is provided with an electrical box maintenance port, and the electrical box cover 114 is movably connected or detachably connected to the cover body 11 to open or close the electrical box maintenance port, thereby facilitating the maintenance of the electrical box.

[0068] Optionally, the connection between the housing body 11 and the electrical box cover 114 can be a sliding connection, a rotating connection or a fixed connection, etc. In this embodiment, Figure 2 As shown, the cover body 11 and the electric box cover 114 are connected by screws and nuts, thereby realizing the connection between the cover body 11 and the electric box cover 114. Under normal circumstances, at least one position on the edge of the electric box cover 114 is connected to the electric box cover 114 by screws. When the operator needs to inspect the electric box, the nut can be unscrewed to inspect the electric box. When the inspection of the electric box is completed, the electric box cover 114 can be connected to the cover body 11 again by the nut.

[0069] Specifically, in order to make the laser processing and the cover move more stably, the protective cover 1 includes a support member 121, which is arranged at the bottom end of the protective cover 1. The support member 121 is slidably connected to the guide rail to further improve the stability of the laser processing and the cover.

[0070] Alternatively, as Figure 3 and Figure 4 As shown, there can be multiple support members 121. Since the length of the connection area between the protective cover 1 and the support members 121 is limited, and too few support members 121 cannot provide support, an equal number of 2-4 support members 121 are provided at the bottom ends of both sides of the protective cover 1 corresponding to the guide rails. In this embodiment, 3 support members 121 are respectively provided at the bottom ends of both sides of the protective cover 1 corresponding to the guide rails.

[0071] Specifically, if Figure 2-4 As shown, to ensure that the operator can clearly see the operating conditions of the laser processing machine inside the cover at any time, at least one protective window 113 is embedded in the protective cover 1. Optionally, to ensure that most of the conditions inside the laser processing machine cover can be seen through the protective windows 113, in this embodiment, two protective windows 113 are provided on the front of the protective cover 1, one protective window 113 is provided on the left side of the protective cover 1, and two protective windows 113 are also provided on the right side of the protective cover 1. Through these arrangements, the operator can basically see the entire operation of the laser processing machine. In other embodiments, any number of protective windows 113 can be provided within the tolerances of the protective cover 1. For example, a protective window 113 can be provided on the rear side of the protective cover 1 to observe the operating conditions of the laser processing machine from the back.

[0072] Specifically, if Figure 1-5 As shown, in this embodiment, a camera 101 is provided in the protective cover 1. The camera 101 obtains image information in the protective cover 1 and transmits it to the display, so that the working status of the laser processing machine can be seen more clearly and specifically.

[0073] Alternatively, as Figure 1-5 As shown, in this embodiment, two cameras 101 are provided, and the two cameras 101 are respectively positioned above the left and right ends of the crossbeam. This allows the cameras 101 to capture a wider range, thereby enabling a smaller number of cameras 101 to clearly observe the operation of the laser processing machine. In other embodiments, the number of cameras 101 can be set to any number that the laser processing and the cover can withstand, but the number should not be too small, as too few cameras 101 may not capture the entire state of the laser processing and operation. The number of cameras 101 should also not be too large, as too many cameras 101 will not only cause functional redundancy but also increase manufacturing costs. For example, the number of cameras 101 can be 3, 4, etc.

[0074] Alternatively, as Figure 1-5 As shown, in this embodiment, to ensure human safety, sensors 102 are installed on the front and / or rear outer walls of the protective cover 1. In this embodiment, sensors 102 are installed on both the front and rear outer walls of the protective cover 1. The sensors 102 sense the human body and then feed the information back to the crossbeam control system, which in turn controls the start and stop of the crossbeam on the guide rail, ensuring that any human body in front of and behind the protective cover 1 is sensed. The crossbeam drives the laser processing machine cover and the laser processing machine to move on the guide rail. When a human body is too close to the laser processing cover, the human body information will be sensed by the sensor 102. The information sensed by the sensor 102 is then fed back to the crossbeam control system via a wiring harness. The crossbeam control system controls the start and stop of the crossbeam, thereby protecting the safety of the operator.

[0075] It should be noted here that the beam control system is an existing structure. Setting up a control system to control the moving components in the design of a laser processing machine is a conventional setting in this field. In this embodiment, any control system in the existing technology can be used, and any connection method in the existing technology can be used to connect to the beam. As long as the beam control system has the control function of starting and stopping the beam, it will not be introduced in detail.

[0076] Optionally, the sensor 102 can be an infrared sensor, a bioelectric induction sensor, an ultrasonic sensor, etc. To ensure that the sensor 102 has high detection sensitivity and high cost performance, in this embodiment, the same type of sensor 102 is used on the front and rear sides of the laser processing machine cover. The sensor 102 is an infrared sensor 102. The infrared sensor 102 is very sensitive to heat source detection, can capture temperature changes almost immediately, and can also perform real-time monitoring. Due to the small size, light weight, and rich interfaces of the infrared sensor 102, it is easier to integrate into various devices.

[0077] Alternatively, as Figure 1 As shown, the signal transmitter and signal receiver of the sensor 102 are arranged on the front side of the protective cover 1, and the signal transmitter and signal receiver of the sensor 102 are respectively located at the left and right ends of the front side of the protective cover 1. The signal transmitter and signal receiver of the sensor 102 are also arranged on the rear side of the protective cover 1, and the signal transmitter and signal receiver of the sensor 102 are also located at the left and right ends of the rear side of the protective cover 1, which can identify the human body in a larger range. In other embodiments, the sensor 102 can be set at other positions as long as it can sense the human body in real time and accurately. For example, the sensor 102 can be set at the upper and lower ends of the front and / or rear side of the protective cover 1.

[0078] Specifically, if Figure 3As shown, in order for the drag chain connected to the laser processing machine to operate normally, a portion of the drag chain is outside the protective cover 1. In this embodiment, a drag chain notch 115 is provided on the protective cover 1. The drag chain notch 115 is used to accommodate the drag chain and connect the drag chains inside and outside the protective cover 1, thereby allowing the laser processing machine to operate normally. Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
