Abstract
Description
Technical Field
[0001] This utility model belongs to the field of local heating cutting technology, specifically relating to laser beam processing, and more particularly to a laser cutting device. Background Technology
[0002] A laser cutting machine is a device that uses a high-energy laser beam to cut materials. With the continuous development of modern industry, laser cutting technology has become an indispensable processing method, playing an important role, especially in manufacturing, automotive industry and aerospace.
[0003] During the cutting process of the laser head, some particulate matter is generated. This particulate matter can pollute the surrounding environment and even cause some harm to people in the vicinity.
[0004] In related technologies, in order to prevent damage caused by flying particles, an outer shell is installed on the laser cutting equipment to cover the entire working platform of the laser cutting equipment, thereby preventing particles from scattering and flying everywhere.
[0005] However, when the work platform is very long, it is very costly to set up an outer shell to cover it, and the presence of the outer shell makes loading extra-long workpieces very inconvenient.
[0006] Therefore, how to prevent damage caused by particulate matter splashing without affecting the feeding of ultra-long workpieces is a technical problem that urgently needs to be solved by those skilled in the art.
[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0009] This disclosure provides a laser cutting device, comprising: a support assembly for placing a substrate to be processed; a guide rail assembly arranged along the length of the support assembly; a cutting mechanism disposed on the guide rail assembly; a protective mechanism covering the periphery of the cutting mechanism; and a control module; wherein the control module is configured to control the cutting mechanism to move along the guide rail assembly to cut the substrate in different areas, while controlling the protective mechanism to move with the cutting mechanism for real-time protection; and the control module is further configured to, during finishing, control the protective mechanism to move with the cutting mechanism to the area of the substrate to be cut, and then control the cutting mechanism to move independently within the protective mechanism to cut the substrate.
[0010] In one optional embodiment, the cutting mechanism includes a laser head and a first driving assembly; the first driving assembly is disposed on a guide rail assembly, and the laser head is disposed on the first driving assembly; the control module is configured to control the first driving assembly to move on the guide rail assembly, so as to drive the laser head to cut the substrate in different areas.

[0012] In one optional embodiment, the guide rail assembly includes: a pair of guide rails arranged along the length direction of the bearing component; the first driving component includes: a pair of first sliders respectively disposed on the corresponding guide rails, the two first sliders being driven by a first driver to move synchronously; the second driving component includes: a pair of second slider groups respectively disposed on the corresponding guide rails, the two second slider groups being driven by a second driver to move synchronously.
[0013] In one optional embodiment, the second slider group includes: a second master slider and a second slave slider; the second driver drives the two second master sliders to move synchronously.
[0014] In one alternative embodiment, the first slider is located between the second master slider and the second slave slider; the control module is configured to control the first driver to move the first slider independently between the second master slider and the second slave slider during finishing, so that the laser head cuts the substrate inside the outer casing.
[0015] In one alternative embodiment, the two ends of the first slider are respectively connected to the second main slider and the second slave slider via dust covers to prevent dust.
[0016] The beneficial effects of this utility model are as follows: First, this laser cutting equipment uses a small protective mechanism that can move with the cutting mechanism, replacing the large and fixed outer shell in the prior art. This not only blocks the flying particles generated by the cutting mechanism, but also occupies only a small part of the area of the supporting components, so as not to affect the feeding of extra-long workpieces.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0029] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0030] like Figure 1 As shown, at least one embodiment provides a laser cutting device, which includes: a support component 1 for placing a substrate to be processed; a guide rail assembly 2 arranged along the length direction of the support component 1; a cutting mechanism 3 disposed on the guide rail assembly 2; a protective mechanism 4 covering the periphery of the cutting mechanism 3; and a control module; wherein the control module is configured to control the cutting mechanism 3 to move along the guide rail assembly 2 to cut the substrate in different areas, while controlling the protective mechanism 4 to move with the cutting mechanism 3 for real-time protection; and the control module is further configured to, during finishing, control the protective mechanism 4 to move with the cutting mechanism 3 to the area of the substrate to be cut, and then control the cutting mechanism 3 to move independently within the protective mechanism 4 to cut the substrate.
[0031] In this embodiment, a small protective mechanism 4 that can move with the cutting mechanism 3 is used instead of the large and fixed outer shell in the prior art. This not only blocks the flying particles generated by the cutting mechanism 3, but also occupies only a small part of the area of the bearing component 1, so as not to affect the feeding of extra-long workpieces. Secondly, when performing finishing, after the control module moves the cutting mechanism 3 and the protective mechanism 4 to the area to be processed, it only controls the movement of the cutting mechanism 3, so as to avoid the protective mechanism 4 from resonating during the following movement, thereby affecting the processing accuracy of the cutting mechanism 3.
[0032] It should be noted that: Figure 1 The top cover of the middle protective mechanism 4 is in the open position to display the internal cutting mechanism 3.
[0033] like Figure 1As shown, in some embodiments, the guide rail assembly 2 includes a pair of guide rails 21 arranged along the length of the support assembly 1.
[0034] like Figure 1 As shown, in some embodiments, the cutting mechanism 3 includes a laser head 31 and a first driving component 32; the first driving component 32 is disposed on the guide rail group 2, and the laser head 31 is disposed on the first driving component 32; the control module is configured to control the first driving component 32 to move on the guide rail group 2, so as to drive the laser head 31 to cut the substrate in different areas.
[0035] In this embodiment, the first driving component 32 includes a pair of first sliders 321, which are respectively disposed on the corresponding guide rails 21, and the two first sliders 321 are driven by the first driver to move synchronously.
[0036] In this embodiment, the first driver may be, but is not limited to, a servo motor. The gear at the drive end of the servo motor meshes with the rack on the guide rail 21 (it may mesh directly or indirectly through a transmission rod). The rotation of the servo motor enables the first slider 321 to move on the guide rail 21.
[0037] like Figure 2 As shown, in some embodiments, the protective mechanism 4 includes: an outer casing 41 and a second driving assembly; the second driving assembly is disposed on the guide rail assembly 2, and the outer casing 41 is disposed on the second driving assembly; the control module is configured to control the second driving assembly to follow the first driving assembly 32 to move on the guide rail assembly 2, so as to drive the outer casing 41 to follow the laser head 31 to move for real-time protection; and the control module is further configured to, during finishing, control the second driving assembly to follow the first driving assembly 32 to move, so as to drive the outer casing 41 to follow the laser head 31 to the area of the substrate to be cut, and then control the first driving assembly 32 to move independently, so that the laser head 31 cuts the substrate inside the outer casing 41.
[0038] In this embodiment, the second driving component includes a pair of second slider groups 421, which are respectively disposed on the corresponding guide rails 21, and the two second slider groups 421 are driven by the second driver to move synchronously.
[0039] In this embodiment, the second driver may be, but is not limited to, a servo motor. The gear at the drive end of the servo motor meshes with the rack on the guide rail 21 (it may mesh directly or indirectly through a transmission rod). The rotation of the servo motor enables the second slider group 421 to move on the guide rail 21.
[0040] Specifically, the laser head 31 and the outer casing 41 are driven by independent drivers, and the control module controls the first driver and the second driver to work respectively; the first slider 321 and the second slider group 421 move synchronously, so that the outer casing 41 can protect the laser head 31 in real time; when fine processing is required, the first slider 321 and the second slider group 421 first move synchronously to the area that basically needs to be processed, and then the second slider group 421 stops sliding, and only the first slider 321 slides as needed, thereby avoiding resonance generated by the second slider group 421 in the process of driving the outer casing 41 to slide.
[0041] like Figure 2 As shown, in some embodiments, the second slider group 421 includes: a second main slider 421a and a second slave slider 421b; a second driver drives the two second main sliders 421a to move synchronously.
[0042] In this embodiment, the first slider 321 is located between the second main slider 421a and the second slave slider 421b; the control module is configured to control the first driver to drive the first slider 321 to move independently between the second main slider 421a and the second slave slider 421b during finishing, so that the laser head 31 cuts the substrate inside the outer casing 41.
[0043] In this embodiment, the distance between the second main slider 421a and the second slave slider 421b is the working area of the first slider 321. During the finishing process, the first slider 321 moves between the second main slider 421a and the second slave slider 421b to cut the substrate inside the outer casing 41.
[0044] like Figure 2 As shown, in some embodiments, the two ends of the first slider 321 are connected to the second main slider 421a and the second slave slider 421b respectively through dust covers 322 to prevent dust.
[0045] In this embodiment, the dust cover 322 is stretched and compressed during the movement of the first slider 321, except that the right end of the first slider 321 in the figure is not connected to the dust cover 322.
[0046] In some embodiments, the control module may be, but is not limited to, a PLC; the control module is configured to control the rotation of the first driver and the second driver to move the corresponding first slider 321 and the second slider group 421 on the guide rail 21, thereby realizing the movement of the laser head 31 and the outer casing 41 in the direction of the guide rail 21.
[0047] It should be noted that the control process of this laser cutting equipment is existing technology, and no creative effort is required for those skilled in the art.
[0048] In summary, this laser cutting equipment uses a small protective mechanism 4 that can move with the cutting mechanism 3, replacing the large and fixed outer shell in the prior art. This not only blocks the flying particles generated by the cutting mechanism 3, but also occupies only a small part of the area of the supporting component 1, without affecting the loading of extra-long workpieces. Secondly, during the finishing process, after the control module moves the cutting mechanism 3 and the protective mechanism 4 to the area to be processed, it only controls the movement of the cutting mechanism 3, avoiding resonance of the protective mechanism 4 during the following movement, which would affect the processing accuracy of the cutting mechanism 3.
[0049] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.
[0050] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.
[0051] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.
[0052] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.
[0053] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.
[0054] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0055] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0056] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0057] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0058] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
