Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a laser processing equipment, aiming to facilitate the discharge of the smoke and dust generated during the operation of the laser processing equipment, so as to improve the processing quality of the workpiece to be processed.

[0006] To achieve the above object, the laser processing equipment proposed by the utility model includes a machine shell and at least two elevation columns;

[0007] The machine shell forms a support surface;

[0008] At least two elevation columns are sequentially arranged on the support surface along a first direction, and each elevation column extends along a second direction. The elevation column is used to support the workpiece to be processed along a third direction, and the first direction, the second direction, and the third direction intersect pairwise.

[0009] Optionally, the elevation column forms a support edge, and the support edge is used to support the workpiece to be processed.

[0010] Optionally, the projection of the support edge is arc-shaped, straight-shaped, or wavy.

[0011] Optionally, the elevation column further forms two abutting edges, and the two abutting edges and the support edge are all arranged in a triangular shape, and the two abutting edges abut against the support surface.

[0012] Optionally, the first wall surface of the elevation column between the support edge and the abutting edge is concave.

[0013] Optionally, the first wall surface is an arc surface.

[0014] Optionally, the second wall surface of the elevation column between the two abutting edges is concave.

[0015] Optionally, the second wall surface is an arc surface.

[0016] Optionally, the abutting edge is arc-shaped.

[0017] Optionally, the distance between the two abutting edges is equal to the distance between the abutting edge and the supporting edge.

[0018] Optionally, the heightening column is provided with a hole; the hole extends along the second direction and at least partially penetrates through the two end faces of the heightening column in the second direction; and / or, the hole is a circular hole.

[0019] Optionally, the laser processing device further includes a bottom plate, the bottom plate forms an installation cavity with an open upper part, the bottom surface of the installation cavity is the supporting surface, and the height of the heightening column is slightly greater than the height of the installation cavity.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited.

[0037] A laser processing device is a device that uses laser as the processing medium to achieve the purpose of processing a workpiece to be processed. Currently, during the use of a laser processing device, the workpiece to be processed is usually directly attached to the bottom plate of the casing of the laser processing device, and the bottom plate is a relatively flat plate structure. This makes the bottom surface of the workpiece to be processed and the bottom plate almost completely attached, and then the smoke and dust generated during the working process of the laser processing device cannot be discharged between the workpiece to be processed and the bottom plate, resulting in the smoke and dust being easily attached to the surface of the workpiece to be processed, making its surface dirty and the cutting lines black, affecting the processing quality of the workpiece to be processed.

[0038] Therefore, based on the above considerations, in order to solve the problem that the smoke and dust generated during the working process of the current laser processing device are inconvenient to discharge inside the casing and affect the processing quality of the workpiece to be processed, this application proposes a new type of laser processing device. This laser processing device innovatively sets up elevation posts on the support surface of the casing to support the workpiece to be processed through the elevation posts. Furthermore, the contact area with the workpiece to be processed is reduced, and a gap for exhaust can be formed between the workpiece to be processed and the support surface to facilitate the discharge of the smoke and dust generated when the laser processing device is working, improving the processing quality of the workpiece to be processed.

[0039] In addition, it should also be noted that the laser processing device proposed in this application can specifically be a laser cutting machine, and of course, it can also be a laser drilling machine, or a laser engraving machine, etc. This application does not limit the specific type of the processing device, as long as it is a device that processes the workpiece to be processed by emitting laser.

[0040] Next, the structure of the laser processing device proposed in this application will be explained and described by way of examples. In an embodiment of this application, please refer to Figure 1 and Figure 2, the laser processing device 100 proposed in this application includes a housing 10 and at least two elevation columns 30. The housing 10 forms a support surface 11; the at least two elevation columns 30 are sequentially arranged on the support surface 11 along a first direction, and each elevation column 30 extends along a second direction. The elevation column 30 is used to support the workpiece to be processed along a third direction, and the first direction, the second direction and the third direction intersect pairwise.

[0041] The housing 10 can serve as the housing structure of the laser processing device 100 for installing other mechanisms of the laser processing device 100. For example: The laser processing device 100 may further include a laser processing head for emitting laser and a driving device for driving the laser processing head to move, so as to realize the moving processing of different parts of the workpiece to be processed. The laser processing head and the driving device can be installed on the housing 10. Further, the support surface 11 on the housing 10 can be arranged facing the laser processing head in the laser processing device 100, so that the workpiece to be processed placed on the support surface 11 can be better corresponded to the laser processing head for processing. Among them, a processing cavity 13 can be arranged in the housing 10 to accommodate mechanisms such as the laser processing head and the elevation column through the processing cavity 13, and then play an isolation and protection role during the working process of the laser processing device 100. At this time, the bottom wall of the processing cavity 13 can be formed as the support surface 11. In addition, in order to facilitate the formation of the processing cavity 13, the housing 10 may include a housing main body 17 and a bottom plate 19. The bottom plate 19 can cover the bottom of the housing main body 17 and enclose the processing cavity 13 with the housing main body 17. At this time, the upper surface of the bottom plate 19 can be formed as the support surface 11.

[0042] The heightening column 30, as the name implies, can be used to support and heighten the workpiece to be processed, avoiding the need for the workpiece to be processed to fit large areas with the relatively large supporting surface 11, and forming a gap between the workpiece to be processed and the supporting surface 11. Among them, the number of heightening columns 30 can be two, three or more, and can be arranged at intervals in sequence, or arranged in abutting sequence in the first direction. When the laser processing device 100 is in a normal use state, the first direction and the second direction can be two intersecting horizontal directions, and the third direction can be the vertical direction. In addition, the heightening column 30 can extend linearly in the second direction. At this time, the heightening column 30 can be a triangular prism structure, or an approximate triangular prism structure, or a four-sided prism structure, or an approximate four-sided prism structure, etc. Of course, the heightening column 30 can also extend in an S shape in the second direction. It can be seen that the present application does not limit the specific structural shape of the heightening column 30, as long as it can ensure that the overall extension direction of the heightening column 30 extends along the second direction. In addition, the heightening column 30 can be detachably arranged on the supporting surface 11 as introduced below, or can also be fixedly arranged on the supporting surface 11. It can be seen that the present application does not limit the connection setting method between the heightening column 30 and the supporting surface 11. In addition, the material of the heightening column 30 can be metal, or can also be plastic.

[0043] When the laser processing device 100 of the technical solution of the present utility model is in use, since at least two heightening columns 30 are arranged on the supporting surface 11 of the machine shell 10, the workpiece to be processed can be supported by the at least two heightening columns 30. In this way, the bottom surface of the workpiece to be processed will not be completely attached to the supporting surface 11 in a large area, but can contact the relatively smaller volume heightening column 30, and a gap can be formed between the workpiece to be processed and the supporting surface 11, which is convenient for discharging the smoke and dust generated during the operation of the laser processing device 100, reducing the possibility of smoke and dust adhering to the surface of the workpiece to be processed and soiling its surface and making the cutting line black, thereby improving the processing quality of the workpiece to be processed. In addition, by heightening the workpiece to be processed by the heightening column 30, a certain distance can also be provided between the workpiece to be processed and the supporting surface 11 of the machine shell 10. Furthermore, when the laser processing device 100 processes the workpiece to be processed, the laser will not process the supporting surface 11 of the machine shell 10, thus avoiding damage to the machine shell 10 of the laser processing device 100 caused by laser processing. In addition, since the heightening column 30 is a columnar structure, its structure is relatively simple, which is conducive to reducing the manufacturing cost.

[0044] In the embodiment as Figure 1 shown, the first direction is the length direction of the laser processing device, the second direction is the width direction of the laser processing device, and the third direction is the height direction of the laser processing device. In other embodiments, the first direction, the second direction and the third direction can also be other directions that intersect pairwise, which are not limited here.

[0045] Please refer to Figures 2 to 4 , in an embodiment of the present application, the elevation post 30 is formed with a support edge 31 for supporting the workpiece to be processed.

[0046] In this embodiment, the elevation post 30 supports the workpiece to be processed through the support edge 31, so that the elevation post 30 and the workpiece to be processed can be in line contact. At this time, the contact area between the elevation post 30 and the workpiece to be processed can be further reduced, thereby reducing the blockage of the discharge of smoke and dust by the elevation post 30, so as to further improve the discharge effect of the smoke and dust generated during the operation of the laser processing device 100.

[0047] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the support edge 31 is arc-shaped, straight, or wavy.

[0048] In Figure 3 and Figure 4 In the shown embodiment, the support edge 31 is set to be arc-shaped, in other words, the support edge 31 is rounded. At this time, on the one hand, the possibility of scratching the surface of the workpiece to be processed by the support edge 31 can be reduced, so that the workpiece to be processed can be more safely supported on the elevation post 30. On the other hand, the possibility of damage caused by the contact and collision between the support edge 31 and foreign objects can also be reduced, and at the same time, the convenience of processing and forming at this place can be improved. In other embodiments, the support edge 31 can also be straight or wavy. Among them, the arc shape, straight shape, or wavy shape described in this embodiment refers to the shape of the cross-section perpendicular to the second direction.

[0049] Please refer to Figures 2 to 4 , in an embodiment of the present application, the elevation post 30 is further formed with two abutting edges 33, and the two abutting edges 33 and the support edge 31 are arranged in a triangle, and the two abutting edges 33 abut against the support surface 11.

[0050] In this embodiment, the elevation post 30 abuts against the support surface 11 through the two abutting edges 33, so that the elevation post 30 can form a triangular structure through the support edge 31 and the two abutting edges 33, and the triangular structure has the characteristic of stability, which is conducive to improving the stability of the elevation post 30 in supporting the workpiece to be processed on the support surface 11, so that the laser processing device 100 can stably process the workpiece to be processed.

[0051] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the first wall surface 35 between the support edge 31 and the abutting edge 33 of the elevation post 30 is concave.

[0052] In this embodiment, the first wall surface 35 is set to be a concave structure, which can further increase the gap between adjacent elevation columns 30, thereby further improving the exhaust effect of the smoke and dust generated during the operation of the laser processing device 100.

[0053] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the first wall surface 35 is an arc surface.

[0054] In this embodiment, setting the first wall surface 35 as an arc surface can, on the one hand, make the shape of the first wall surface 35 more regular, thus facilitating its processing and forming. On the other hand, it also enables the elevation column 30 to have a better guiding effect on the smoke and dust generated during the operation of the laser processing device 100 through the first wall surface 35, so as to discharge them in time. Of course, it should be noted that in other embodiments, it is also possible to directly form a concave setting by opening a triangular or square groove on the first wall surface 35.

[0055] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the abutting edge 33 is arc-shaped.

[0056] In this embodiment, setting the abutting edge 33 as an arc shape, in other words, performing a chamfering setting on the abutting edge 33. At this time, on the one hand, it can reduce the possibility of the abutting edge 33 scratching the surface of the support surface 11, so that the support surface 11 can safely support the elevation column 30. On the other hand, it can also reduce the possibility of the abutting edge 33 being damaged due to contact and collision with external objects, and at the same time improve the convenience of processing and forming at this place.

[0057] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the second wall surface 37 between the two abutting edges 33 of the elevation column 30 is concave.

[0058] In this embodiment, setting the second wall surface 37 as a concave structure enables the elevation column 30 to abut against the support surface 11 only through the two abutting edges 33, so as to ensure that the elevation column 30 can be stably arranged on the support surface 11, thereby improving the support effect of the elevation column 30 on the workpiece to be processed.

[0059] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the second wall surface 37 is an arc surface.

[0060] In this embodiment, setting the second wall surface 37 as an arc surface can make the shape of the second wall surface 37 more regular, thereby facilitating its processing and forming. Of course, it should be noted that in other embodiments, it is also possible to directly form a concave setting by opening a triangular or square groove on the second wall surface 37.

[0061] Please refer to Figure 3 and Figure 4 , in an embodiment of the present application, the distance between the two abutting edges 33 is equal to the distance between the abutting edge 33 and the supporting edge 31.

[0062] In this embodiment, setting the distance between the two abutting edges 33 to be equal to the distance between the abutting edge 33 and the supporting edge 31 can make the connection lines between the supporting edge 31 and the two abutting edges 33 enclose an equilateral triangle on a projection plane perpendicular to the first direction. At this time, the structure of the heightening column 30 can be made more regular, that is, the shapes and structures of the abutting edge 33 and the supporting edge 31 can be the same, and the shapes and structures of the first wall surface 35 and the second wall surface 37 can also be the same, which is beneficial to improving the convenience of processing and forming the heightening column 30. Moreover, during actual use, any edge of the heightening column 30 can be formed as the abutting edge 33. That is, the user can set any side of the heightening column 30 facing the supporting surface 11, and the edge facing away from the supporting surface 11 is formed as the abutting edge 33. At this time, since any side of the heightening column 30 can be set facing the supporting surface 11, the requirement for the placement posture of the heightening column 30 on the supporting surface 11 is reduced, which is beneficial to improving the convenience of setting the heightening column 30 on the supporting surface 11.

[0063] Please refer to Figure 3 , in an embodiment of the present application, the heightening column 30 is provided with a hole 39.

[0064] In this embodiment, by providing the hole 39, the weight of the heightening column 30 can be reduced, and the effect of lightening the weight of the heightening column 30 can be improved. At this time, when the heightening column 30 is detachably arranged on the supporting surface 11, it is more beneficial to improve the convenience of taking and placing the heightening column 30. On the other hand, such a setting can also reduce the raw materials required for manufacturing the heightening column 30, which is beneficial to reducing the manufacturing cost of the heightening column 30. Among them, the hole 39 can be arranged to extend along the first direction as introduced below, or can also be arranged on the side circumference of the heightening column 30. In addition, the hole 39 can be a circular hole as introduced below, or can also be a square hole or a hole with other shapes. In addition, the number of the holes 39 can be one, or can also be two or more.

[0065] Please refer to Figure 3 and Figure 4, in an embodiment of the present application, the hole 39 extends along a first direction and at least partially penetrates through both end faces of the spacer post 30 in the first direction.

[0066] In this embodiment, the hole 39 penetrates through both end faces of the spacer post 30 in the first direction, so that the structure of the hole 39 can be relatively simple, which is convenient for improving the convenience of processing and forming it on the spacer post 30. At the same time, it can also improve the weight reduction effect of the spacer post 30 and improve the fluidity of the air flow in the processing cavity 13, thereby further improving the discharge effect of the smoke and dust generated during the operation of the laser processing device 100. Of course, in other embodiments, the hole 39 may also only penetrate through one end face of the spacer post 30 in the first direction, that is, partially penetrate the spacer post 30.

[0067] Please refer to Figure 3 or Figure 4 , in an embodiment of the present application, the hole 39 is a circular hole.

[0068] In this embodiment, setting the hole 39 as a circular shape can make the shape of the hole 39 very regular, which is conducive to further improving the convenience of processing and forming it. In addition, the setting of the hole 39 also facilitates the smooth demolding of the spacer post 30 and avoids deformation that affects the straightness of the spacer post 30 in the extending direction.

[0069] In an embodiment of the present application, the spacer post 30 is detachably provided on the support surface 11.

[0070] In this embodiment, setting the spacer post 30 to be detachable on the support surface 11 can, on the one hand, facilitate the user to arrange the quantity and arrangement interval of the spacer posts 30 according to needs, which is conducive to improving the flexibility of using the spacer posts 30. On the other hand, when the spacer post 30 is damaged, it can be replaced relatively conveniently. Among them, the detachable setting of the spacer post 30 can include two situations. The first situation is that there is no connection relationship between the spacer post 30 and the support surface 11, and the spacer post 30 is directly movably abutted on the support surface 11 to omit the connection structure between the support surface 11 and the spacer post 30 and improve the convenience of manufacturing it. The second situation is that there is a connection relationship between the spacer post 30 and the support surface 11, and magnetic attraction connection or snap connection can be adopted, which can improve the stability of the support post on the support surface 11 at this time.

[0071] Please refer to Figure 2 , in an embodiment of the present application, at least two spacer posts 30 are spaced apart in the first direction.

[0072] In this embodiment, at least two elevation posts 30 are arranged at intervals in the first direction. On the one hand, the gap between two adjacent elevation posts 30 can be increased to reduce the blockage of the elevation posts 30 to the discharge of smoke and dust, thereby further improving the discharge effect of the smoke and dust generated during the operation of the laser processing device 100. Among them, the intervals can be equal intervals or non-equal intervals.

[0073] Please refer to Figure 2 , in an embodiment of the present application, the length of the elevation post 30 in the second direction is slightly less than the length of the support surface 11 in the second direction.

[0074] In this embodiment, in the second direction, the elevation post 30 is set to be slightly less than the length of the support surface 11, so that there is an interval between the elevation post 30 and the two cavity walls of the processing cavity 13 in the second direction. At this time, the fluidity of the air flow in the processing cavity 13 can be improved, so as to further improve the discharge effect of the smoke and dust generated during the operation of the laser processing device 100. Of course, the present application is not limited to this. In other embodiments, the length of the elevation post 30 in the second direction may also be equal to the length of the support surface 11 in the second direction. Among them, in the second direction, the length of the elevation post 30 being slightly less than the length of the support surface 11 may mean that the difference in length between the elevation post 30 and the support surface 11 is less than 10%, 5%, etc. of the length of the support surface 11, or the difference is less than a preset value.

[0075] Please refer to Figure 1 and Figure 5 , in an embodiment of the present application, the bottom plate 19 forms an installation cavity with an upper opening. The bottom surface of the installation cavity is the support surface 11, and the height of the elevation post 30 is slightly greater than the height of the installation cavity. In this way, there can be a gap between the bottom surface of the workpiece to be processed and the upper surface of the bottom plate 19, which is convenient for air flow. Among them, slightly greater means that the difference between the two is less than a predetermined value or the difference between the two is less than a preset percentage (such as 10%, 5%, etc.) of the height of the installation cavity.

[0076] Please refer to Figure 1 and Figure 5 , in an embodiment of the present application, the machine shell 10 is further provided with an exhaust port 15, and the exhaust port 15 communicates with the processing cavity 13.

[0077] In this embodiment, by providing the exhaust port 15 and cooperating with the fan device, the fluidity of the air flow can be improved, so as to better drive the gas in the processing cavity 13 to be discharged from the exhaust port 15, thereby improving the discharge effect of the smoke and dust generated during the operation of the laser processing device 100.

[0078] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application by using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
