Description

Technical Field

[0001] This application relates to the technical field of cutting equipment, and particularly to a laser cutting device for a mounting plate of a stage light. Background Art

[0002] A stage light mounting plate is a device for fixing and installing stage lights. It is usually made of metal or other strong materials and has multiple hole positions or fixtures, which can conveniently fix various types of stage lights in the required positions. When cutting the mounting holes on the mounting plate, the mounting plate needs to be placed on the workbench of the laser cutting device, supported by support bars (sword grids), and finally cut by the laser cutting device. During the cutting process, slag will adhere to the support bars, and then workers need to use special tools to clean the slag on multiple support bars.

[0003] For example, the Chinese patent document with the publication number CN220480586U discloses a slag cleaning device for the sword grid of a laser cutting machine, including a sword grid and a bottom plate arranged on the sword grid. Two support plates are vertically and fixedly arranged on the bottom plate. A support pin shaft is arranged between the two support plates, and a rotating sleeve is sleeved outside the support pin shaft. A scraper and a crowbar are fixedly arranged on the outer wall of the rotating sleeve. A rectangular groove for avoiding the scraper is formed on the bottom plate, and the support plates are respectively arranged on both sides of the rectangular groove; the front end of the scraper is upturned and the connection part is a smooth arc. A notch is formed on the scraper, and the width of the notch is slightly larger than the width of the sword grid, and the notch has a slope with a narrower upper part and a wider lower part. A protective cover is installed on the bottom plate, and the protective cover is located above the scraper. A reinforcing plate is fixedly arranged on the bottom surface of the scraper, and the reinforcing plate is fixedly connected with the rotating sleeve. When too much slag accumulates on the sword grid and needs to be cleaned, the slag cleaning device is moved onto the sword grid, the notch of the scraper is used to clamp the sword grid to be cleaned, and the crowbar is manually pulled to clean the slag one by one.

[0004] In the above related technologies, when cleaning the support bars on the laser cutting device, first, the slag cleaning device needs to be moved onto the sword grid, then the single sword grid is aligned with the notch on the scraper, then the notch of the scraper is used to clamp the sword grid to be cleaned, the crowbar is manually pulled to move the scraper upward, and then the slag on the sword grid is cleaned. Workers also need to push the slag cleaning device along the length direction of the sword grid to clean the entire sword grid. After cleaning one sword grid, workers also need to adjust the position of the slag cleaning device to clean the slag on multiple support bars one by one, resulting in a decrease in the cleaning efficiency of the slag on the support bars. Summary of the Invention

[0005] This application provides a laser cutting device for a mounting plate of a stage light, aiming to solve the problem of low cleaning efficiency of the slag on the support bars in the related technologies.

[0006] The laser cutting device for the mounting plate of a stage light provided by this application adopts the following technical solution: A laser cutting device for the mounting plate of a stage light, comprising a frame, a laser cutting body arranged on the frame, and a plurality of support bars arranged on the frame for supporting the mounting plate. It is characterized in that: a bending component for simultaneously bending the plurality of support bars is arranged on the frame. The bending component includes two moving rods slidably connected to the frame and a positioning plate arranged on the frame. The two moving rods are arranged at both ends of the support bar, and a plurality of positioning plates are arranged. The plurality of positioning plates correspond to the plurality of support bars one by one, and the positioning plate is arranged at the middle position of the support bar. A plurality of clamping grooves for clamping the support bar are formed on the moving rod. The opening of the clamping groove is arranged downward, and a positioning groove for limiting the bent support bar is arranged on the positioning plate. The two sides of the opening of the positioning groove are symmetrically arranged as arc surfaces. A driving component for driving the two moving rods to move simultaneously is arranged on the frame.

[0007] By adopting the above technical solution, after the laser cutting is completed, the driving component drives the two moving rods to slide simultaneously. During the sliding process, due to the effect of the arc-shaped positioning groove on the positioning plate, the middle position of the support bar can be limited, and then the two ends of the support bar can be driven to move. At this time, the support bar will be bent. During the bending process, the side surface of the support bar will abut against the arc surface on the positioning groove. During the reciprocating movement of the support bar, the support bar bends in two directions. At this time, the slag on the support bar will become loose. Since all the support bars can be bent simultaneously, the cleaning process is relatively convenient and can be cleaned multiple times during actual use. When the cleaning frequency increases, the slag on the support bar will also decrease accordingly. Thus, by bending, a part of the loose slag on the support bar can automatically fall off, achieving the purpose of facilitating the cleaning of the slag.

[0008] Optionally, an installation frame is slidably connected to the frame. The moving rod is slidably connected to the installation frame, and a control cylinder for driving the installation frame to slide in the vertical direction is arranged on the frame. A plurality of cleaning sleeves for cleaning the slag on the support bar are fixedly installed on the frame. The cleaning sleeve is used to sleeve on the support bar, and the plurality of cleaning sleeves correspond to the plurality of support bars one by one.

[0009] By adopting the above technical solution, when the bending component drives the support bar to bend and makes the slag on the support bar become loose, at this time, the control cylinder drives the installation frame to move downward, and then the cleaning sleeve is sleeved on the support bar. At this time, a part of the remaining slag on the support bar will be pushed off, thus achieving the purpose of cleaning the slag on multiple support bars simultaneously. Since the slag on the support bar becomes loose, it can also be more labor-saving during the cleaning process.

[0010] Optionally, a pushing component for pushing the moving rod away from the plurality of support bars is provided on the mounting frame. The pushing component includes a moving block fixedly connected to the moving rod, and a moving groove, an upward moving groove, a returning groove, and a downward falling groove formed in the mounting frame. The moving groove, the upward moving groove, the returning groove, and the downward falling groove are connected end to end, and the moving block is slidably connected in the moving groove, the upward moving groove, the returning groove, and the downward falling groove. A lifting component for pushing the moving block at the connection of the moving groove and the upward moving groove to the connection of the upward moving groove and the returning groove is provided on the mounting frame. When the moving block is at the connection of the upward moving groove and the returning groove, the support bar disengages from the clamping groove.

[0011] By adopting the above technical solution, during the sliding process of the moving rod, the moving block on the moving rod slides in the moving groove. When the support bar is completely abutted against the arc surface, the moving block moves to the connection of the moving groove and the upward moving groove, and then the lifting component pushes the moving block to move in the direction of the connection of the upward moving groove and the returning groove. The upward movement of the moving block will also drive the upward movement of the moving rod. When the moving block is at the connection of the upward moving groove and the returning groove, both ends of the support bar disengage from the clamping groove. Finally, the support bar automatically resets under its own elastic force. During the reset process, the support bar will have a swinging vibration, so that the slag on the support bar can be better loosened and fallen off, and then the slag falling on the support bar is reduced.

[0012] Optionally, the lifting component includes a lifting plate slidably connected to the mounting frame and a lifting spring fixed to the lifting plate. The end of the lifting spring away from the lifting plate is fixed to the mounting frame, and the lifting spring is used to push the lifting plate to move from the bottom wall of the moving groove to the connection of the upward moving groove and the returning groove. A downward pressing component for keeping the lifting plate at the bottom wall of the moving groove is provided on the lifting plate.

[0013] By adopting the above technical solution, when the moving block moves to the connection of the moving groove and the upward moving groove, the lifting plate moves upward, and then the lifting plate pushes the moving block upward, and finally it is convenient for the clamping groove on the moving rod to disengage from the support bar.

[0014] Optionally, the downward pressing component includes a horizontal plate fixed to the lifting plate, an inclined plate fixed to the horizontal plate, and a downward pressing wheel rotatably connected to the moving block. The inclined plate gradually slopes downward along the direction away from the horizontal plate, and the downward pressing wheel abuts against the inclined plate.

[0015] By adopting the above technical solution, during the movement of the moving rod, it will drive the moving block to slide in the moving groove. The moving block drives the downward pressing wheel to move. The downward pressing wheel pushes the inclined plate to move, and then the inclined plate drives the lifting plate to move downward. The lifting spring is compressed, and finally the lifting plate is moved below the moving block, which is convenient for pushing the moving block upward.

[0016] Optionally, a plurality of rotating balls are rotatably connected to the inner wall of the clamping groove, and the rotating balls are used to abut against the surface of the support bar.

[0017] By adopting the above technical solution, while the moving block drives the moving rod to move upward, under the action of the rotating ball, the friction between the support bar and the inner wall of the clamping groove is reduced, which facilitates the separation of the support bar from the clamping groove.

[0018] Optionally, a plurality of the pushing components and the lifting components are provided.

[0019] By adopting the above technical solution, under the action of a plurality of the pushing components and the lifting components, the movement of the moving rod upward is more stable.

[0020] Optionally, a cleaning component for cleaning the slag between adjacent tooth tips on the support bar is provided on the frame. The cleaning component includes a cleaning bar slidably connected to the frame and a plurality of cleaning teeth fixed on the cleaning bar. The gaps between the cleaning teeth correspond to the gaps between adjacent tooth tips on the support bar. A control component for driving the cleaning bar to reciprocate is provided on the frame.

[0021] By adopting the above technical solution, the control component drives the cleaning bar to reciprocate, and the slag between the tooth tips on the support bar can be cleaned by the cleaning teeth on the cleaning bar, so that the cleaning effect of the slag on the support bar is better.

[0022] Optionally, the driving component includes a driving cylinder fixed on the mounting frame and a driving plate fixed on the driving cylinder. The moving rod is slidably connected to the control plate in the vertical direction.

[0023] By adopting the above technical solution, the driving cylinder drives the moving rod to reciprocate. During the upward movement of the moving block, the moving rod slides on the driving plate, and then the moving rod can be better driven to reciprocate.

[0024] Optionally, a support plate for supporting the support bar in the clamping groove is provided on the mounting frame.

[0025] By adopting the above technical solution, under the action of the support plate and the limiting plate, the support bar can be more stable after the clamping groove and the support bar are separated.

[0026] In summary, the present application includes the following beneficial technical effects: After the support bar bends and swings, the slag on the support bar becomes loose. At this time, the control cylinder drives the mounting frame to move downward, and then the cleaning sleeve is sleeved on the support bar. At this time, a part of the remaining slag on the support bar is pushed away, so as to achieve the purpose of cleaning the slag on a plurality of support bars at the same time. Since the slag on the support bar becomes loose, it is also more labor-saving during the cleaning process. Description of the Drawings

Detailed implementation manners

[0037] The following Figures 1 - 9 will further elaborate on the present application in detail.

[0038] An embodiment of the present application discloses a laser cutting device for the mounting plate of a stage light. Referring to Figure 1 and Figure 2, a laser cutting device for the mounting plate of a stage light, including a frame 01 and a laser cutting body 02 arranged on the frame 01. An installation frame 03 is slidably connected to the frame 01. A plurality of support bars 04 are arranged on the installation frame 03. The support bars 04 are in a serrated structure and are evenly spaced along the length direction of the frame 01. And a bending assembly 1 is arranged on the installation frame 03. The bending assembly 1 is used to bend the plurality of support bars 04. By bending the support bars 04 in two directions, the slag on the support bars 04 can be loosened, and part of the slag will fall off automatically, thereby achieving the purpose of facilitating the cleaning of the slag.

[0039] Refer to Figures 2 - 5 , the bending assembly 1 includes a moving rod 11 slidably connected to the installation frame 03 and a positioning plate 12 arranged on the frame 01. Two moving rods 11 are provided. The two moving rods 11 are arranged at both ends of the support bar 04. The moving rod 11 is slidably connected to the installation frame 03 along the length direction of the installation frame. A plurality of clamping grooves 13 are formed in the moving rod 11. The openings of the clamping grooves 13 face downward. The plurality of clamping grooves 13 correspond to the plurality of support bars 04 one by one. And a support plate 14 for supporting the support bar 04 is fixedly installed on the installation frame 03. When the support bar 04 is completely located in the clamping groove 13, the support bar 04 abuts against the support plate 14. At the same time, a positioning groove 15 is formed in the positioning plate 12. The positioning groove 15 penetrates through the positioning plate 12 along the length direction of the support bar 04. And both sides of the positioning groove 15 facing away from the ground opening are arc-shaped surfaces 16. The positioning plate 12 is arranged at the middle position of the support bar 04.

[0040] Since a plurality of support bars 04 are simultaneously clamped in the clamping grooves 13, when the two moving rods 11 move simultaneously, under the action of the positioning plate 12, the middle position of the support bar 04 is supported and limited. At this time, the support bar 04 will adhere to the arc-shaped surface 16. When the moving rod 11 moves in the reverse direction, the bent support bar 04 can be attached to the arc-shaped surface 16 on the other side. By reciprocating the moving rod 11, the slag on the support bar 04 can be made more relaxed. In addition, since there is no need to use a separate slag cleaning device to clean each support bar 04, only the two moving rods 11 need to move simultaneously. At this time, the frequency of cleaning the slag on the support bar 04 can be increased, and the slag on the support bar 04 can be cleaned when there is a small amount of slag attached to the support bar 04, and then the amount of slag on the support bar 04 can be reduced.

[0041] Refer to Figures 2 - 6, a plurality of cleaning sleeves 2 are fixedly installed on the frame 01. The plurality of cleaning sleeves 2 correspond to the plurality of support bars 04 one by one, and the positioning plate 12 is fixed on the cleaning sleeve 2. The cleaning sleeve 2 is arranged below the positioning plate 12. In addition, a control cylinder 21 is arranged on the frame 01. The control cylinder 21 is fixedly connected to the mounting frame 03. By driving the control cylinder 21, the mounting frame 03 moves up and down. During the downward movement of the mounting frame 03, the moving rod 11, the support plate 14 and the plurality of support bars 04 clamped in the clamping groove 13 will be driven to move downward. Then the support bars 04 will move into the cleaning sleeve 2, and the loose slag on the support bars 04 will be scraped off by the cleaning sleeve 2, so as to achieve the purpose of cleaning the slag on the plurality of support bars 04 at the same time, and further improve the cleaning efficiency of the slag on the support bars 04.

[0042] Refer to Figures 1 - 2 , a driving component 3 is arranged on the mounting frame 03. The driving component 3 is used to drive the moving rod 11 to reciprocate along the length direction of the frame 01. In this embodiment, since two moving rods 11 are provided, two driving components 3 are also provided. The driving component 3 includes a driving cylinder 31 fixed on the mounting frame 03 and a driving plate 32 fixed on the piston rod of the driving cylinder 31. The moving rod 11 is slidably connected to the driving plate 32 in the vertical direction. By the operation of the driving cylinder 31, the driving plate 32 can be driven to move. The movement of the driving plate 32 drives the moving rod 11 to reciprocate on the mounting frame 03, and then the plurality of support bars 04 inserted into the clamping groove 13 are bent simultaneously.

[0043] Refer to Figure 2 , Figures 7 - 8 , a pushing component 4 is arranged on the mounting frame 03. After the support bar 04 is bent in one direction, the pushing component 4 is used to push the support bar 04 out of the clamping groove 13 on the moving rod 11. Then the support bar 04 will shake under the action of its own elasticity and finally return to its original shape. During the shaking process of the support bar 04, the slag on the support bar 04 will fall off more quickly, which is convenient for subsequent cleaning of the slag on the support plate 14.

[0044] Refer to Figure 2 , Figures 7 - 8, the driving component 4 includes a moving block 41 fixed on the moving rod 11 and a moving groove 42, an upward moving groove 43, a returning groove 44, and a falling groove 45 formed on the mounting frame 03. The moving groove 42, the upward moving groove 43, the returning groove 44, and the falling groove 45 are connected end to end, and then a figure-eight structure will be formed on the mounting frame 03. In the initial state, the moving block 41 is located in the moving groove 42. At the same time, a lifting component 5 is provided on the mounting frame 03. When the moving block 41 moves to the position where the moving groove 42 communicates with the upward moving groove 43, the lifting component 5 drives the moving block 41 to move upward. Then, when the moving block 41 moves to the position where the upward moving groove 43 communicates with the returning groove 44, the clamping groove 13 and the support bar 04 are disengaged, so that the bent support bar 04 will bend in the reverse direction. During the reverse bending process, the support bar 04 will swing reciprocally, thereby facilitating the detachment of the loosened slag.

[0045] Refer to Figure 2 , Figures 7 - 8 , in the initial state, the moving block 41 is located at the communicating position of the falling groove 45 and the moving groove 42. During the downward movement of the mounting frame 03, since the positioning groove 15 on the moving block 41 clamps the support bar 04, at this time, the support bar 04, the moving block 41, and the moving rod 11 cannot move downward. When the top wall of the communicating position of the returning groove 44 and the falling groove 45 on the mounting frame 03 abuts against the moving block 41, the mounting frame 03 will push the moving block 41 downward. At this time, the moving block 41 drives the moving rod 11 to move downward, and the moving rod 11 is used to push multiple support bars 04 downward, thereby facilitating the cleaning sleeve 2 to clean the slag on the support bar 04.

[0046] Refer to Figure 2 , Figures 7 - 8 , the lifting component 5 includes a lifting plate 51 slidably connected to the mounting frame 03 and a lifting spring 52 fixed on the lifting plate 51. The end of the lifting spring 52 away from the lifting plate 51 is fixed on the mounting frame 03. At the same time, a pressing component 6 is provided on the lifting plate 51. During the movement of the moving block 41 in the moving groove 42, it can move downward through the lower pressing plate, and then compress the lifting spring 52. When the moving block 41 moves to the position where the moving groove 42 communicates with the upward moving groove 43, the lifting plate 51 is located below the moving block 41. Then, the lifting spring 52 pushes the lifting plate 51 and the moving block 41 abutting on the lifting plate 51 to move upward. During the upward movement of the moving block 41, it will drive the moving rod 11 to move. Finally, it is convenient for the support bar 04 to disengage from the clamping groove 13. Then, during the upward movement of the moving rod 11, the moving rod 11 slides on the driving plate 32. Since the lifting plate 51 is located below the moving block 41, the moving block 41 at the communicating position of the upward moving groove 43 and the returning groove 44 can be supported by the lifting plate 51.

[0047] When the moving block 41 moves to the connection between the upward movement groove 43 and the return groove 44, the driving cylinder 31 drives the driving plate 32 to move in the reverse direction. The driving plate 32 drives the moving rod 11 to move in the reverse direction. The moving block 41 slides in the return groove 44, and then the moving block 41 will move to the connection between the return groove 44 and the falling groove 45, and the clamping groove 13 corresponds to the reset support bar 04. At this time, the moving rod 11 can slide in the falling groove 45 under the action of gravity. During the sliding process, the clamping groove 13 will be sleeved on the support bar 04, which is convenient for driving multiple support bars 04 to bend subsequently. To improve the stability of the upward movement of the moving rod 11, a plurality of lifting components 5 and pushing components 4 are arranged on the installation frame 03. The plurality of lifting components 5 and the plurality of pushing components 4 correspond one by one. Refer to Figure 4 , Figures 7 - 8 , in order to facilitate the separation of the support bar 04 from the moving rod 11, a plurality of rotating balls 22 are rotatably connected to the inner wall of the clamping groove 13. The rotating balls 22 abut against the surface of the support bar 04. A pressing rod (not shown in the figure) is fixed on the frame 01 by bolts. The pressing rod is used to abut against the upper surface of the support bar 04, and can limit the support bar 04 during the upward movement of the moving rod 11 to prevent the support bar 04 and the moving rod 11 from moving upward at the same time. When installing and removing the support bar 04, the pressing rod can be removed from the frame 01, and the pressing rod is fixed on the frame 01 after the support bar 04 is installed.

[0048] Refer to Figure 2 , Figures 7 - 8 , the pressing-down component 6 includes a horizontal plate 61 fixed on the lifting plate 51, an inclined plate 62 fixed on the horizontal plate 61, and a pressing-down wheel 63 rotatably connected to the moving block 41. The inclined plate 62 gradually slopes downward along the direction away from the horizontal plate 61. The pressing-down wheel 63 abuts against the inclined plate 62. When the moving block 41 falls under the action of gravity to the connection between the falling groove 45 and the moving groove 42, the pressing-down wheel 63 abuts against the inclined plate 62. Then, during the process of the moving rod 11 driving the moving block 41 to move, the inclined plate 62 can be pushed downward. During the downward movement of the inclined plate 62, the lifting plate 51 will be pushed downward. When the moving block 41 moves to the connection between the moving groove 42 and the upward movement groove 43, the lifting plate 51 is located below the moving block 41, and then the lifting spring 52 is in a compressed state, which is convenient for pushing the moving block 41 upward.

[0049] Refer to Figure 2 and Figure 9 , a cleaning component 7 for cleaning the slag between adjacent tooth tips on the support bar 04 is arranged on the frame 01. The cleaning component 7 includes a cleaning bar 71 slidably connected to the frame 01 and a plurality of cleaning teeth 72 fixed on the cleaning bar 71. The cleaning teeth 72 correspond to the gaps between adjacent tooth tips on the support bar 04. A control component 8 for driving the cleaning bar 71 to move reciprocally is arranged on the frame 01.

[0050] Reference Figure 2 and Figure 9 Figure 9 , the control component 8 includes a control screw rod 81 rotatably connected to the mounting frame 03 and a control motor 82 fixed to the mounting frame 03. The output shaft of the control motor 82 is fixedly connected to the control screw rod 81. The control screw rod 81 penetrates through the cleaning strip 71 and is threadedly connected to the cleaning strip 71. By driving the control screw rod 81 to rotate through the control motor 82, and then driving the control strip to move by the control screw rod 81, the slag between adjacent tooth tips on the support strip 04 is cleaned, thereby reducing the slag on the support strip 04.

[0051]

[0051] The implementation principle of a laser cutting device for a mounting plate of a stage light in an embodiment of the present application is as follows: after the mounting plate is cut and the support strip 04 needs to be cleaned, the driving component 3 drives the moving rod 11 to move, and then the moving block 41 moves in the moving groove 42. When the moving block 41 moves to the position where the moving groove 42 communicates with the upward moving groove 43, the support strip 04 bends, and the bent support strip 04 is in full contact with the arc surface 16. At the same time, the lifting plate 51, the moving block 41 and the moving rod 11 move upward, and the clamping groove 13 is disengaged from the support strip 04. The support strip 04 swings reciprocally under its own elastic action, so that the loose slag automatically falls off. When the support strip 04 stops swinging and returns to its original state, the driving component 3 makes the moving block 41 move in the reverse direction, and the moving block 41 drives the moving rod 11 to move in the return groove 44. When the moving block 41 moves to the position where the return groove 44 communicates with the falling groove 45, the moving block 41 falls to the initial position under the action of gravity, and then the control cylinder 21 drives the mounting frame 03 to move downward. The mounting frame 03 drives the moving rod 11 and the support strip 04 to move downward. At this time, the remaining slag on the support strip 04 is cleaned by the cleaning sleeve 2, thereby improving the cleaning efficiency of the slag.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
