Detailed implementation manners

[0019] The following is a detailed description of the specific embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

These are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation of the present disclosure. For example, referring to Figure 1 , Figure 1 the upper side in the drawing direction of Figure 1 is the "upper" side, and the upper side in the drawing direction of

[0021] is the "lower" side. "Inner" and "outer" refer to the inside and outside of the corresponding structural contour. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "coupled", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0022] As Figures 1 to 9 shown, the present disclosure provides a laser cutting device, including a laser cutter 10, a dust removal mechanism 20, a position adjustment mechanism 30, and a workbench 40. The workbench 40 is used to support the laser cutter 10, the dust removal mechanism 20, and the position adjustment mechanism 30. The dust removal mechanism 20 includes a housing 21. An accommodation cavity 211 is formed in the housing 21. The accommodation cavity 211 has opposite first and second open ends. A cutting opening 212 communicating with the accommodation cavity 211 is formed at the top of the housing 21. The cutting opening 212 is used for the nozzle of the laser cutter 10 to insert and move. The position adjustment mechanism 30 includes a cutting table 31 and a first driving component 32. The cutting table 31 is movably arranged in the accommodation cavity 211 and has a first position close to the cutting opening 212 and a second position away from the cutting opening 212. The cutting table 31 is used to support the workpiece. Wherein, in the first position, the cutting table 31 is located below the cutting opening 212. The first driving component 32 is in transmission connection with the cutting table 31 to drive the cutting table 31 to move in the accommodation cavity 211.

[0023] Through the above technical solution, with the provided housing 21, the nozzle of the laser cutter 10 can be inserted into the accommodation cavity 211 of the housing 21 through the cutting opening 212 formed at the top of the housing 21, so as to directly act on the workpiece placed on the cutting table 31. In this way, on the one hand, it can effectively control and reduce the dust and particulate matter generated during the laser cutting process, avoid the risk of waste residue splashing, provide a cleaner working environment and extend the service life of the equipment; on the other hand, it can play a certain sound insulation role and provide a quieter working environment for the staff. Moreover, with the provided first driving member 32, the cutting table 31 can move within the accommodation cavity 211 through the first driving member 32, and has a first position close to the cutting opening 212 and a second position away from the cutting opening 212. Thus, according to the actual cutting requirements, the position of the workpiece within the accommodation cavity 211 can be adjusted through the first driving member 32 to achieve the best cutting effect, thereby realizing the automatic position adjustment of the cutting table 31, improving the work efficiency and cutting accuracy. The laser cutting device of the present disclosure integrates the laser cutter 10, the dust removal mechanism 20 and a flexible position adjustment mechanism, and can not only achieve efficient and precise cutting operations, but also ensure the cleanliness and safety of the working environment, while helping to protect the equipment from dust and thus extending its service life.

[0024] As an implementation manner, as Figures 1 to 3 shown, the dust removal mechanism 20 includes an air supply device, a dust collection hood 22 and an air extraction device. The housing 21 includes a first top plate 213 and two first side plates 214. The cutting table 31 includes a connecting plate 311 and two second side plates 312. The two first side plates 214 are respectively connected to both ends of the first top plate 213. A cutting opening 212 is formed on the first top plate 213. The workbench 40, the first top plate 213 and the two first side plates 214 jointly enclose the accommodation cavity 211. The two second side plates 312 are respectively connected to both ends of the connecting plate 311 and extend in the same direction. The ends of the two second side plates 312 away from the connecting plate 311 are slidably connected to the top of the workbench 40. In the first position, the cavity wall of the accommodation cavity 211 and the outer side wall of the cutting table 31 jointly define a dust removal cavity 50. The air supply device is located at the first open end and is used to communicate with the air inlet of the dust removal cavity 50 to supply air to the dust removal cavity 50. The dust collection hood 22 is located at the second open end. One end of the dust collection hood 22 is communicated with the air outlet of the dust removal cavity 50. The air extraction device is communicated with the other end of the dust collection hood 22 to extract the air in the dust removal cavity 50 from the air outlet. Among them, along the direction from the housing 21 to the air extraction device, the cross-sectional area of the dust collection hood 22 gradually decreases.

[0025] Among them, an air supply device (not shown) is located at the first open end of the housing 21 and communicates with the air inlet of the dust removal chamber 50. The air supply device is used to supply air into the dust removal chamber 50, which helps to form a directional air flow during the cutting process and push the generated waste residue towards the direction of the dust collection hood 22.

[0026] Among them, the dust collection hood 22 is arranged at the second open end of the housing 21, and one end of the dust collection hood 22 is connected to the air outlet of the dust removal chamber 50. Since the cross-section of the dust collection hood 22 gradually decreases along the direction from the housing 21 to the air extraction device, the gas flow velocity can be increased in this way, and the collection efficiency of the waste residue can be improved.

[0027] Among them, an air extraction device (not shown) is connected to the other end of the dust collection hood 22 and is used to extract the air containing waste residue from the dust removal chamber 50. In this way, the waste residue generated during the cutting process can be quickly removed, which is beneficial to maintaining a good working environment.

[0028] Among them, through the arranged housing 21, workbench 40, air supply device, dust collection hood 22 and air extraction device, a relatively enclosed space can be provided for the cutting process.

[0029] Specifically, when the cutting table 31 is in the first position, the cavity wall of the accommodation cavity 211 and the outer side wall of the cutting table 31 jointly define a dedicated dust removal chamber 50. In this position, the air supply device can supply air into the dust removal chamber 50, while the air extraction device can extract air from the dust collection hood 22, thereby forming an effective air flow path and effectively removing the waste residue generated during the cutting process from the dust removal chamber 50.

[0030] As an implementation manner, as Figures 1 to 3 shown, the dust removal chamber 50 includes a first cavity 51 and a second cavity 52 that communicate with each other. The air supply device includes a first air supply device and a second air supply device. The first cavity 51 is adjacent to the cutting table 31 in the height direction of the cutting table 31, and the second cavity 52 is adjacent to the cutting table 31 in a direction perpendicular to the height direction of the cutting table 31. The first cavity 51 and the second cavity 52 jointly surround the cutting table 31. The first air supply device is used to communicate with the first cavity 51, and the second air supply device is used to communicate with the second cavity 52.

[0031] Among them, by setting the first air supply device and the second air supply device and performing air supply operations on the first cavity 51 and the second cavity 52 respectively, effective control of the waste residue generated during the cutting process in multiple directions can be achieved.

[0032] Among them, since the first cavity 51 and the second cavity 52 jointly surround the cutting table 31, and each cavity has an independent air supply device to provide a directional air flow, the dust diffusion paths that may occur during the cutting process can be more comprehensively covered, thereby improving the dust removal efficiency.

[0033] As an implementation manner, as Figures 1 to 3 shown, two second cavities 52 are respectively provided on the opposite sides of the cutting table 31. The two second cavities 52 and the first cavity 51 form a U shape. There are two second air supply devices, and each second air supply device communicates with the corresponding second cavity 52. Among them, the wind speed of each second air supply device is less than that of the first air supply device.

[0034] It should be understood that the waste residue in the first cavity 51 is a large amount of waste residue (smoke, fine particles and larger molten metal slag) generated during the cutting process, and the waste residue in the second cavity 52 is the waste residue splashing or diffusing from the inner side of the first cavity 51 (which can be understood as light waste residue). That is to say, the waste residue in the second cavity 52 includes two parts. One part can be part of the waste residue generated during the cutting process, and the other part can be part of the waste residue in the first cavity 51 that is laterally splashed or diffused into the second cavity 52 when the airflow of the first air supply device blows the first cavity 51.

[0035] Among them, the first air supply device is used to supply airflow to the first cavity 51. The direction of the airflow of the first air supply device is from the first open end of the housing 21 to the second open end, and the waste residue in the first cavity 51 can be blown to the dust collection hood 22.

[0036] Among them, the second air supply device is used to supply airflow to the corresponding second cavity 52. The direction of the airflow of the second air supply device is from the first open end of the housing 21 to the second open end, which helps to control the laterally splashed or diffused waste residue, and can blow the waste residue in the second cavity 52 to the dust collection hood 22 while avoiding interfering with the cutting process.

[0037] Among them, since the cutting point is in the first cavity 51, the amount of waste residue generated in the first cavity 51 is the largest and the most concentrated. A higher wind speed can quickly blow a large amount of waste residue to the dust collection hood 22, thereby reducing the chance of waste residue deposition in the cavity and being beneficial to improving the overall dust removal efficiency.

[0038] In other implementation manners, the first cavity 51 and the second cavity 52 can also form an L shape, that is, the cutting table 31 is located at the edge of one of the side cavity walls of the accommodation cavity 211.

[0039] In order to prevent the waste residue in the first cavity 51 from spraying out from the cutting opening 212, as an implementation manner, the airflow direction of the first air supply device can be designed to be slightly inclined downward (towards the cutting table 31). In this way, the upward diffused waste residue generated during the cutting process can be guided downward into the dust removal cavity 50, thereby avoiding the accumulation or reverse escape of waste residue near the cutting opening 212 due to the airflow being too horizontal.

[0040] As an implementation manner, asFigure 4 As shown, the cutting table 31 further includes a stop portion 313. The second side plate 312 includes an arc plate 3121. Stop portions 313 are formed at the top of one side of the connecting plate 311 close to the corresponding second side plate 312. The stop portions 313 extend along the extending direction of the connecting plate 311. The first end of the arc plate 3121 is connected to the connecting plate 311, and the second end of the arc plate 3121 is slidably connected to the workbench 40.

[0041] Among them, through the provided stop portion 313, on the one hand, it can play a role in positioning the workpiece; on the other hand, it can block part of the waste residue in the first cavity 51 from directly entering the second cavity 52, thereby effectively reducing the amount of waste residue in the second cavity 52.

[0042] As an implementation manner, as Figure 4 、 Figure 5 、 Figure 7 and Figure 8 shown, the position adjustment mechanism 30 further includes a bracket group. The first driving component 32 includes a first driving member 321 and a transmission component 322. The second side plate 312 further includes a slider 3122. The transmission component 322 includes a transmission rod 3221, two first bevel gears 3222, two second bevel gears 3223, a screw group and a base 3224. The bracket group is installed on the workbench 40 and includes two brackets 33. The two brackets 33 are arranged at the same horizontal interval. The screw group includes two screws 3225. The two screws 3225 are arranged at the same horizontal interval. Each screw 3225 is rotatably installed on the corresponding bracket 33. The axial direction of the output shaft of the first driving member 321 is set at an angle with the axial direction of each screw 3225. The output shaft of the first driving member 321 is connected to one end of the transmission rod 3221. Two first bevel gears 3222 are sleeved on the transmission rod 3221. Each screw 3225 is sleeved with a second bevel gear 3223. Each second bevel gear 3223 meshes with the corresponding first bevel gear 3222. The top of the base 3224 is connected to the bottom of the connecting plate 311. Two threaded holes penetrating the base 3224 are formed on the base 3224. Each screw 3225 passes through the corresponding threaded hole and is in threaded cooperation with the corresponding threaded hole. A slider 3122 is provided at the second end of each arc plate 3121. Two sliding grooves 41 are formed on the workbench 40. The two sliding grooves 41 are arranged at the same horizontal interval. Each slider 3122 is slidably fitted in the corresponding sliding groove 41. The first driving member 321 is located in the accommodating cavity 211 and is installed on the workbench 40. The first driving member 321 is used to drive the transmission rod 3221 to rotate, so that the base 3224 drives the cutting table 31 to be able to move in the accommodating cavity 211.

[0043] Among them, when the first driving member 321 starts to work, the first driving member 321 can drive the transmission rod 3221 to rotate. Since the two first bevel gears 3222 on the transmission rod 3221 are respectively engaged with the second bevel gears 3223 on each screw 3225, the rotational motion of the transmission rod 3221 can be converted into the rotational motion of the two screws 3225. As the screws 3225 rotate, since the threaded holes on the base 3224 are in threaded fit with the screws 3225, the base 3224 (and the cutting table 31 on the base 3224) can move along the axial direction of the screws 3225. If it is necessary to adjust the position of the cutting table 31, only the rotation direction of the first driving member 321 needs to be changed.

[0044] Among them, sliders 3122 are provided at the second ends of each arc-shaped plate 3121, and each slider 3122 can slide in a chute 41 on the corresponding workbench 40. Such a design can not only provide an external guiding effect, but also reduce friction, which is beneficial to improving the stability and smoothness during the movement of the cutting table 31.

[0045] As an implementation manner, as Figures 5 to 6 shown, the chute 41 includes a first groove body 411 and a second groove body 412 that are communicated with each other. The slider 3122 includes a connecting portion 31221, a connecting block 31222, a first mounting plate 31223, a second mounting plate 31224, a first ball 31225, and a second ball 31226. The connecting portion 31221 is disposed in the first groove body 411. One end of the connecting portion 31221 is connected to the second end of the arc-shaped plate 3121, and the other end of the connecting portion 31221 is connected to the top of the first mounting plate 31223. A first arc-shaped groove 3123 for accommodating the first ball 31225 is formed on the top surface of the connecting block 31222, and a second arc-shaped groove 3124 for accommodating the second ball 31226 is formed on the bottom surface of the connecting block 31222. The first mounting plate 31223 is connected to the top of the connecting block 31222. A first tapered hole 3125 adapted to the first ball 31225 is formed on the first mounting plate 31223. Part of the first ball 31225 protrudes from the first tapered hole 3125 and is slidably connected to the top of the second groove body 412. The second mounting plate 31224 is connected to the bottom of the connecting block 31222. A second tapered hole 3126 adapted to the second ball 31226 is formed on the second mounting plate 31224. Part of the second ball 31226 protrudes from the second tapered hole 3126 and is slidably connected to the bottom of the second groove body 412.

[0046] Among them, by providing the first ball 31225 and the second ball 31226, the contact area between the slider 3122 and the chute 41 can be reduced, thereby greatly reducing the frictional resistance and extending the service life of the chute 41 and the slider 3122.

[0047] Among them, the slider 3122 contacts the top and bottom of the second groove body 412 through two upper and lower ball bearings (the first ball bearing 31225 and the second ball bearing 31226) respectively, which can form a two-way support, avoid the shaking or offset of the slider 3122 during the movement, and improve the stability of the device.

[0048] As an implementation method, as Figure 6 shown, the top surface of the connecting block 31222 has a first central axis arranged along the length direction of the connecting block 31222, the bottom surface of the connecting block 31222 has a second central axis arranged along the length direction of the connecting block 31222, there are multiple first arc grooves 3123, and the multiple first arc grooves 3123 are arranged at intervals along the length direction of the connecting block 31222 and form two parallel first arc groove groups, and the two first arc groove groups are symmetrically arranged with the first central axis as the symmetry axis. Among them, the number of the first tapered holes 3125, the number of the first ball bearings 31225 and the number of the first arc grooves 3123 correspond one by one. There are multiple second arc grooves 3124, and the multiple second arc grooves 3124 are arranged at intervals along the length direction of the connecting block 31222 and form a second arc groove group. The second arc groove group is located on the second central axis. Among them, the number of the second tapered holes 3126, the number of the second ball bearings 31226 and the number of the second arc grooves 3124 correspond one by one.

[0049] Since the connecting part 31221 is located on the first central axis, and the first arc groove group is symmetrically distributed with the first central axis as the symmetry axis, such a design can make the force on the top of the slider 3122 in the chute 41 uniform. Moreover, the symmetrically distributed first ball bearings 31225 can share the force from the connecting part 31221, and can avoid the inclination or jamming of the slider 3122 caused by eccentric force.

[0050] As an implementation method, as Figures 7 to 8As shown, each bracket 33 includes a second top plate 331 and a plurality of third side plates 332 surrounding the second top plate 331. The second top plate 331 and the plurality of third side plates 332 together define a cavity 333. At least one of the third side plates 332 is provided with an opening 334 communicating with the cavity 333. The opening 334 is for the edge of the corresponding base 3224 to be inserted and moved. Each bracket 33 further includes a partition 335 located in the cavity 333 to partition out a first chamber 3331 and a second chamber 3332. The first driving member 321 is located outside one of the brackets 33. The output shaft of the first driving member 321 is arranged to be inserted into the first chamber 3331 of one of the brackets 33. One end of the transmission rod 3221 is rotatably connected to the inner wall of one of the two first chambers 3331. The other end of the transmission rod 3221 is located in the other of the two first chambers 3331 and is in transmission connection with the output shaft of the first driving member 321. A through hole is formed in the partition 335. One end of the screw 3225 passes through the through hole and is sleeved with a second bevel gear 3223. The other end of the screw 3225 is rotatably connected to the inner wall of the second chamber 3332.

[0051] By providing the bracket group, it is possible to effectively prevent the waste residues generated during the cutting process from adhering to the first driving component 32, thereby extending the service life of the equipment.

[0052] Among them, through a clever layout, components such as the transmission rod 3221 and the screw 3225 are integrated inside the bracket 33, which can not only save space but also improve the compactness of the device, facilitating maintenance and operation.

[0053] Among them, the partition 335 can not only partition out the first chamber 3331 and the second chamber 3332, but also provide a support point for the screw 3225, enabling the screw 3225 to rotate smoothly inside the bracket 33.

[0054] In order to enable workpieces of different heights or thicknesses to smoothly enter the accommodation chamber 211, therefore, as an implementation manner, such as Figure 4 、 Figure 7 、 Figure 9As shown, the position adjustment mechanism 30 further includes a second driving member 34. The second driving member 34 includes a second driving part 341, a first telescopic rod 342 and a second telescopic rod 343. The second side plate 312 further includes an adjusting part 3127. The adjusting part 3127 is configured as a folding spring structure. One end of the adjusting part 3127 is connected to the second end of the arc plate 3121, and the other end of the adjusting part 3127 is connected to one end of the connecting part 31221. A receiving groove 3226 is formed on the base 3224. The second driving part 341 is located in the receiving groove 3226. The first telescopic rod 342 is arranged vertically. The top of the first telescopic rod 342 is connected to the bottom of the connecting plate 311, and the bottom of the first telescopic rod 342 is connected to the second driving part 341 in a transmission connection. The second driving part 341 can drive the first telescopic rod 342 to extend or shorten. There are multiple second telescopic rods 343. The multiple second telescopic rods 343 are arranged at intervals along the circumferential direction of the base 3224. The tops of the multiple second telescopic rods 343 are connected to the bottom of the connecting plate 311, and the bottoms of the multiple second telescopic rods 343 are connected to the top of the base 3224.

[0055] Among them, through the cooperation of the second driving part 341 and the first telescopic rod 342, the cutting table 31 can be automatically adjusted to a suitable height so that workpieces of different heights or thicknesses can smoothly enter the accommodating cavity 211, which is beneficial to improving the versatility and flexibility of the device.

[0056] Among them, through the arrangement of the multiple second telescopic rods 343, on the one hand, a stable supporting surface can be formed, which can make the connecting plate 311 always remain horizontal when adjusting the height, and can avoid structural problems caused by uneven single-point stress; on the other hand, it helps to evenly distribute the load on the base 3224, thereby reducing local stress concentration and extending the service life of the equipment.

[0057] Among them, when the height of the connecting plate 311 changes, the folding spring structure can undergo elastic deformation to compensate for the height change. For example, if the connecting plate 311 rises, the adjusting part 3127 is in a tensile state; if the connecting plate 311 drops, the adjusting part 3127 is in a compressed state. In this way, the design of the adjusting part 3127 can automatically adapt to the height change of the connecting plate 311 without external manual adjustment, thus simplifying the operation process and improving production efficiency. And the folding spring structure can provide a certain buffer when the workpiece contacts the cutting table 31, which can reduce the impact on the equipment, and at the same time can also adapt to slight height differences to ensure the stable placement of the workpiece. In addition, the folding spring structure can help form a specific air flow channel. When the second air supply device blows air into the second cavity 52, the adjusting part 3127 can play a role in guiding the air flow to more effectively take away the waste residue. That is to say, the adjusting part 3127 can not only play a supporting and buffering role, but also assist in air flow management, which can improve the waste residue removal efficiency.
