Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a novel laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam is irradiated onto the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, thereby completing the cutting.

[0003] Currently, laser cutting produces smoke and dust, which is a significant amount after cutting. This smoke and dust pose a certain health hazard to workers. Smoke and dust are generally fine particles and easily adhere to the machine. Failure to promptly remove them can affect the appearance and even cutting accuracy of the cutting machine, further impacting its operation. Existing laser cutting machines often have extraction devices located at the material receiving area, below the laser cutting table. After cutting, the smoke and dust typically float upward, preventing them from being immediately removed, resulting in unabsorbed smoke.

[0004] The laser beam emitted by a laser cutting machine is not absolutely parallel but has a certain divergence angle. As the laser beam travels over long distances, its diameter expands, causing focal spot instability and directly affecting cutting quality. Controlling beam variation can be achieved through optical lenses, which typically achieve a beam variation of less than 3 mm. However, due to the relatively short lifespan and high price of transmission lenses, maintenance costs are high.

[0005] There is a knife bar on the workbench of the laser cutting machine. The upper side of the knife bar is in the shape of a knife tip. The whole is formed by stretching an isosceles triangle-like plane. Multiple knife bars are combined to form a material discharge platform. After the blank is placed on the discharge platform, the platform will become uneven due to the gravity of the blank and the knife holder or the knife bar holder is not positioned accurately during installation, making the blank placed on the platform uneven, causing the cutting surface of the blank to tilt during laser cutting, affecting the laser cutting quality. Summary of the Invention

The support plate 10507 is fixed.

[0063] Specific route of laser emission: the laser emitter emits a laser beam which enters the incident hole of the first reflector, is reflected by the first reflector and then emitted from the reflective hole. The emitted laser beam enters the incident hole of the second reflector and then is reflected by the second reflector and then emitted from the reflective hole. Similarly, the laser beam passes through the third, fourth, and fifth reflectors 10402, 10403, and 10305 in sequence and is finally emitted from the laser gun 10306.

[0064] The principle of constant light path in this application is as follows:

[0065] Assume that the distance between the emitted laser beam and the first reflector is X;

[0066] Assume that the distance between the emitted laser beam and the second reflector is Y;

[0067] Assume that the distance between the emitted laser beam and the third reflector 10402 is M;

[0068] Assume that the distance between the emitted laser beam and the third reflector 10402 and the fourth reflector 10403 is Z;

[0069] Assume that the distance between the emitted laser beam and the fourth reflector 10403 and the fifth reflector 10305 is N;

[0070] Let the total distance of the emitted laser beam be L;

[0071] L=X+Y+M+Z+N. In the prior art, the distances of X, Y, Z, and M remain unchanged, and the distance that changes is N. Therefore, the total distance L of the laser beam in the prior art will change. In this application, the distances of X, Y, and Z remain unchanged, and the distances that change are M and N. M+N (before movement) = M+N (after movement). The specific principle is as follows:

[0072] For example, when the motor and reducer 10304 control the helical gear to move in the positive direction of X, the moving distance is 20 cm. Because the active moving device 104 is fixed to the synchronous belt 10508, the moving distance of the synchronous belt pressure strip 10506 is also 20 cm. Since the support plate 10507 is fixed to the upper side of the synchronous belt 10508, the synchronous belt 10508 will pull the driven moving device 4 to move in the positive direction of X. Due to the setting of the synchronous belt 10508, the distance moved by one side of the synchronous belt 10508 is twice the overall movement of the synchronous belt 10508. The driven moving device 10508 is 4 moves 10 cm along the positive X direction. It can be inferred that the distance M is reduced by 10 cm on the original basis, and the distance N is the distance of the laser beam from the fourth reflector 10402 to the fifth reflector 10403. Since the fourth reflector 10402 is set on the driven moving device 104, the driven moving device 104 moves 10 cm along the positive X direction, and the fifth reflector 105 is set on the active moving device 103 and moves 20 cm along the positive X direction, it can be concluded that the distance N increases by 20 cm - 10 cm = 10 cm, so the total distance L remains unchanged.

[0073] The motor and the reducer 10304 are used to rotate the gears to drive the active moving device 103 to move (the active moving device 103 is provided with a fifth reflector 10305 and a laser gun 10306), and the active moving device 103 is fixed to the driven moving device 104 (the driven moving device 104 is provided with a third and fourth reflectors 10402 and 10403) through the synchronous belt auxiliary device 105. Due to the setting of the synchronous belt 10508, when the synchronous belt 10508 moves one end distance, the driven moving device 104 moves half of the distance, and the active moving device 103 moves the same distance in the same direction, so that the entire laser beam The path length does not change; and the rotation accuracy is made more precise by controlling the motor and the reducer 10304; the meshing overlap of the helical gear and the helical rack is large, the transmission is stable, and the noise is low; and the third and fourth reflectors 10402 and 10403 on the usually fixed driven moving device 104 of the common laser cutting machine are not provided with a synchronous belt auxiliary device 105, and the cutting position of the laser gun 10306 is controlled only by the active moving device 103. When the equipment is improved to a constant light path, only a slider is provided under the driven moving device 104, and a synchronous belt auxiliary device 105 is added, so as to facilitate the advanced replacement of old equipment.

At 0518, the smoke chamber A30511 is provided with a smoke hole 30515 and a smoke strip opening 30516. During the smoke extraction process during workpiece cutting, smoke generated by laser cutting of the workpiece flows through the smoke hole 30515 and smoke strip opening 30516 into the smoke chamber A30511. From there, the smoke enters the smoke chambers B30512 on either side. The smoke chambers B30512 on either side enter the smoke chamber C30513. The smoke in the smoke chamber C30513 then enters the smoke outlet A3051, passes through the duct interface 3052, enters the smoke duct 3053, and then enters the exhaust fan from the smoke duct 3053, ultimately being discharged into the processing area.

[0077] Furthermore, since the smoking chamber B30512 is arranged on both sides of the smoking chamber A30511, and the suction force near the interface between the smoking chamber A30511 and the smoking chamber B30512 is relatively large, in order to ensure uniform suction force at the smoking strip opening 30516 and the smoking hole 30515, the smoking hole 30515 is arranged on the lower side of the smoking chamber of the base 101, and the smoking holes 30515 and the smoking strip opening 30516 are relatively dense on both sides and in the middle of the smoking chamber A30511.

[0078] Furthermore, the pipe interface part 3052 is provided with a smoking pipe interface hole 30522 and a mounting hole A30521, and the smoke outlet A30514 is evenly provided with mounting holes B30517. The mounting holes A30517 and the mounting holes B30521 are fixed to the smoke outlet A30514 by bolts and nuts.

[0079] Furthermore, the pipe interface part 3052 is a rectangular cavity structure, and the opening direction of the smoking pipe interface hole 30522 is parallel to the upper surface of the base smoking cavity 3051.

[0080] Furthermore, since the base smoking chamber 3051 is set below the base 101, and the base 101 can move on the movable slide rail 7 according to the processing position of the workpiece, the base smoking chamber 3051 is always located above the processed workpiece, so that the smoke generated by cutting the workpiece floats upward and enters the base smoking chamber 3051 as soon as possible, and the laser gun 10306 can move back and forth on the base 101 according to the processing position.

[0081] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
