Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a follow-up dust collection device for a laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] However, existing laser cutting machines generally use passive dust collection, with the splashed waste falling directly into the cutting machine, making it inconvenient to collect the waste and clean the machine. At the same time, when processing some toxic materials, such as beryllium bronze, the high temperature will produce toxic fumes. Without an effective way to collect the fumes, they will diffuse into the processing environment, affecting the health of the operators. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of collecting waste and cleaning the machine body, and the lack of an effective way to collect the fumes generated during cutting, which causes the fumes to diffuse in the processing environment and affect the health of operators. Therefore, this invention proposes a follow-up dust collection device for laser cutting machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser cutting machine follow-up dust collection device includes a machine body, the top wall of the machine body is densely covered with dust outlet mesh holes, and each dust outlet mesh hole side wall is provided with multiple support teeth. A laser emitter is provided above the machine body, and a planar moving mechanism for driving the laser emitter to move is also provided at the upper end of the machine body.

[0007] The laser emitter is equipped with a laser base, and a laser emitting head is connected to the lower end of the laser base. The laser base is also equipped with a follow-up dust collection mechanism. The follow-up dust collection mechanism includes an annular tube arranged outside the laser emitting head. Multiple dust collection tubes are passed through the lower end of the annular tube. A flexible hose is connected through the annular tube, and the other end of the flexible hose is connected to the dust collection end of a small vacuum cleaner.

[0008] The inner cavity of the machine body is equipped with a dust collection box with an open upper end that slides in relation to the laser emitter. The dust collection box is connected to a planar moving mechanism. An air suction pipe is connected through the side wall of the dust collection box and is connected to the air suction end of the vacuum cleaner. The vacuum cleaner is fixedly installed in the inner cavity of the machine body.

[0009] Preferably, the planar moving mechanism includes lead screws horizontally rotatably mounted on both sides of the top wall of the machine body, a drive assembly for driving the lead screws to rotate on one side of the machine body, a slider threadedly connected to each lead screw, and a groove corresponding to the slider on the top wall of the machine body, a linear motor connected between the two sliders, and a slide seat slidably mounted on the linear motor.

[0010] More preferably, the drive assembly includes a servo motor installed on one side of the bottom wall of the machine body, and synchronous pulleys are sleeved on the output end of the servo motor and on one side of the two lead screws, and synchronous belts are connected between the synchronous pulleys.

[0011] More preferably, the mini vacuum cleaner is mounted on the upper end of one of the sliders, and the dust collection box is connected to the sliders at both ends.

[0012] Preferably, the laser emitter is provided with a rotating seat, which is rotatably mounted on the side wall of the slide seat. A mounting base is rotatably mounted on the rotating seat, and a small motor for driving the mounting base to rotate is provided inside the rotating seat. The laser base is fixedly mounted on the side wall of the mounting base.

[0013] Preferably, the plurality of suction tubes are evenly distributed in a multi-layered ring on the bottom wall of the ring tube.

[0014] Preferably, a corrugated hose is also connected between the plurality of suction pipes and the bottom wall of the annular pipe.

[0015] Preferably, the suction ends of the plurality of vacuum tubes are provided with beveled ports, and the beveled ports are all facing the laser emitting head.

[0016] Preferably, the dust collection box is provided with suction pipes on both sides, and two vacuum cleaners are also provided in the inner cavity of the machine body. The dust collection box is provided with a diversion block corresponding to the suction pipe.

[0017] More preferably, both of the two suction pipes are provided with drag chains on their outer sides, and the inner cavity of the machine body is provided with horizontal support grooves corresponding to the drag chains.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the follow-up dust collection mechanism moves with the laser emitter head, and when the laser emitter head is performing laser cutting, it works with the dust collection tube to absorb the fumes generated during cutting, effectively ensuring the dust collection effect of the fumes;

[0020] 2. In this invention, the outer side of the laser emitter is kept relatively closed by the multi-layered ring-shaped dust suction pipe, and the inclined port ensures the effect of suction of cutting fumes, preventing the fumes from escaping and effectively protecting the health of the operators.

[0021] 3. In this invention, the vacuum pipe is installed with a corrugated hose. When the laser emitter head is tilted for cutting, it maintains a certain vertical state under the action of gravity, ensuring a relatively closed state on one side of the laser emitter head, generating a good negative pressure effect, thereby improving the absorption capacity of smoke during tilted cutting.

[0022] 4. In this invention, the dust collection box that moves with the planar moving mechanism collects the waste chips splashed during laser cutting, and two vacuum cleaners ensure the effective collection of waste chips, keep the machine clean, avoid frequent maintenance of the machine, and extend the service life of the laser cutting machine.

[0023] This invention features a reasonable design and novel structure. Multiple suction pipes arranged in a multi-layered ring, combined with angled ports, ensure good absorption of fumes during laser cutting. The accompanying dust collection box ensures effective collection of waste chips, effectively guaranteeing the collection of fumes and waste chips during laser cutting. This facilitates waste chip collection and also protects the health of operators. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0032] Example 1

[0033] Reference Figure 1-5 A follow-up dust collection device for a laser cutting machine includes a body 1. The top wall of the body 1 is densely covered with dust outlet mesh holes 101, and the side walls of the dust outlet mesh holes 101 are provided with multiple support teeth 102. A laser emitter 5 is provided above the body 1. The upper end of the body 1 is also provided with a planar moving mechanism 2 for moving the laser emitter 5, ensuring that the laser emitter 5 can be moved to any position on the plane, ensuring the processing capacity of the laser cutting machine, and ensuring the use effect of the laser cutting machine.

[0034] The laser emitter 5 is equipped with a laser base 53, and a laser emitter head 54 is connected to the lower end of the laser base 53. The laser base 53 is also equipped with a follow-up dust collection mechanism 6. The follow-up dust collection mechanism 6 includes an annular tube 61 arranged outside the laser emitter head 54. Multiple dust collection tubes 63 are connected through the lower end of the annular tube 61. A flexible hose 64 is connected through the annular tube 61. The other end of the flexible hose 64 is connected to the dust collection end of a small vacuum cleaner 65. When the laser emitter head 54 is working, the dust collection tubes 63 move with the laser emitter head 54. When the laser emitter head 54 is performing cutting processing, it works with the small vacuum cleaner 65 to absorb the dust generated during cutting, preventing the dust generated by laser cutting from spreading in the processing environment and protecting the health of the operators.

[0035] The inner cavity of the machine body 1 is provided with a dust collection box 7 with an open upper end, which is slidably provided corresponding to the laser emitting head 54. The dust collection box 7 is connected to the planar moving mechanism 2. A suction pipe 72 is connected through the side wall of the dust collection box 7. The suction pipe 72 is connected to the suction end of the vacuum cleaner 73. The vacuum cleaner 73 is fixedly installed in the inner cavity of the machine body 1. When the laser emitting head 54 is performing cutting processing, the material waste ejected falls into the dust collection box 7 through the dust outlet mesh 101. The vacuum cleaner 73 then sucks out the waste to complete the collection, ensuring the dust collection effect during laser cutting.

[0036] During laser cutting, a small vacuum cleaner 65 keeps the air inlet of the suction pipe 63 under negative pressure to absorb the fumes generated during cutting. For materials such as beryllium bronze, which produce toxic fumes during processing, this effectively reduces the toxicity and protects the health of operators. At the same time, during processing, the dust collection box 7 collects the splashed debris from below. The waste debris falling through the dust outlet mesh 101 is collected by the dust collection box 7 in conjunction with the vacuum cleaner 73, ensuring a clean cutting process, keeping the machine body 1 clean, and avoiding frequent maintenance of the machine body 1. The follow-up dust collection mechanism 6 effectively ensures the performance of the laser cutting machine and prevents the escape of processing fumes from the processing environment.

[0037] In this embodiment, as Figure 1-5 As shown, the planar moving mechanism 2 includes lead screws 21 horizontally rotatably mounted on both sides of the top wall of the machine body 1. A drive assembly 3 for driving the lead screws 21 to rotate is provided on one side of the machine body 1. Each lead screw 21 is threaded with a slider 22, and a groove is opened on the top wall of the machine body 1 corresponding to the slider 22. A linear motor 4 is connected between the two sliders 22. A slide block 41 is slidably mounted on the linear motor 4. The drive assembly 3 drives the two lead screws 21 to rotate synchronously, controls the sliders 22 to slide, and then drives the linear motor 4 to slide on the machine body 1. The linear motor 4 also drives the slide block 41 to slide, precisely controlling the movement of the laser emitting head 54 at any position on the horizontal plane, ensuring the processing capacity and processing accuracy of the laser cutting machine.

[0038] In this embodiment, as Figure 2-5 As shown, the drive assembly 3 includes a servo motor 33 installed on one side of the bottom wall inside the machine body 1. The output end of the servo motor 33 and one side of the two lead screws 21 are each fitted with a synchronous pulley 31. A synchronous belt 32 is connected between the synchronous pulleys 31. The synchronous rotation of the two lead screws 21 is ensured by the cooperation of the synchronous pulleys 31 and the synchronous belt 32, which ensures the movement accuracy of the laser emitter head 54 and the processing accuracy.

[0039] In this embodiment, as Figure 1-5 As shown, the small vacuum cleaner 65 is installed on the upper end of one of the sliders 22, which facilitates movement with the laser emitter 54 and ensures the dust collection effect. The dust collection box 7 is connected to the slider 22 at both ends to ensure that the dust collection box 7 moves with the laser emitter 54 and ensures the dust collection effect during cutting.

[0040] Example 2

[0041] Reference Figure 1-5In this embodiment, it is basically the same as in Embodiment 1, but with an optimization: the laser emitter 5 is provided with a rotating seat 51, which is rotatably mounted on the side wall of the slide 41. A mounting seat 52 is rotatably mounted on the rotating seat 51, and a small motor for driving the mounting seat 52 to rotate is provided inside the rotating seat 51. The small motor can be a brushless motor to ensure the control accuracy of the rotation angle. The laser base 53 is fixedly mounted on the side wall of the mounting seat 52. The rotating seat 51 drives the laser emitter head 54 to rotate, which facilitates the adjustment of the rotation angle of the laser emitter head 54, improves the adaptability to different processing requirements, and improves the processing capacity of the laser cutting machine.

[0042] Example 3

[0043] Reference Figure 1-5 In this embodiment, it is basically the same as in Embodiment 1, but with an optimization: the multiple suction pipes 63 are evenly distributed in a multi-layered ring on the bottom wall of the ring pipe 61, forming a relatively closed space around the laser emitter 54, which improves the suction effect of the suction pipes 63 and enhances the suction capacity for the smoke generated during cutting.

[0044] In this embodiment, as Figure 1-5 As shown, a corrugated hose 62 is also connected between the multiple suction pipes 63 and the bottom wall of the annular pipe 61, so that the suction pipes 63 can maintain a certain vertical state under gravity, and ensure a suitable distance between the laser emitting head 54 and the cutting material on one side when the laser emitting head 54 is tilted, maintain a relatively closed state around the laser emitting head 54, and ensure the suction capacity of the laser emitting head 54 for dust when it is tilted during processing.

[0045] In this embodiment, as Figure 1-5 As shown, the suction ends of the multiple suction pipes 63 are all provided with angled ports 631, and the angled ports 631 are all facing the side of the laser emitter 54. The angled ports 631 ensure the suction capacity of the smoke at the laser emitter 54 and ensure the follow-up suction effect.

[0046] Example 4

[0047] Reference Figure 2-5 In this embodiment, it is basically the same as in embodiment one, but it is further optimized in that the dust collection box 7 is provided with suction pipes 72 on both sides, and two vacuum cleaners 73 are also provided in the inner cavity of the body 1. The dust collection box 7 is provided with a diversion block 71 corresponding to the suction pipe 72. The diversion block 71 avoids the accumulation of waste in the dust collection box 7, and the two vacuum cleaners 73 improve the dust collection ability.

[0048] In this embodiment, as Figure 2-5As shown, both suction pipes 72 are equipped with drag chains 8 on their outer sides, and a support groove plate 81 corresponding to the drag chain 8 is horizontally provided in the inner cavity of the body 1. The drag chain 8 controls the curling state of the suction pipe 72 when the laser emitter 54 moves, ensuring the conduction state of the suction pipe 72 when the laser emitter 54 moves, avoiding the folding of the suction pipe 72, and also ensuring the smooth movement of the laser emitter 54. This prevents the suction pipe 72 from getting tangled and affecting the movement effect of the laser emitter 54, thus ensuring the effectiveness of the follow-up dust collection device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
