Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a laser cutting head structure for long stroke applications. Background Technology

[0002] Laser cutting machines are devices that use high-energy laser beams to precisely cut materials. Due to their high efficiency, high precision, and non-contact processing characteristics, they are widely used in important fields such as metal processing, electronics and electrical appliances, and energy conservation and environmental protection.

[0003] Traditional laser cutting machines on the market have fixed laser generators that are separate from the laser head. The laser generator does not move during the cutting process and remains stationary, while the laser head slides along a guide rail. The laser beam generated by the laser generator is reflected by a mirror and sent to the laser head for laser cutting. However, for laser cutting tables with a large travel distance, the laser beam will lose energy during transmission due to the long travel distance. At the same time, the laser will also be affected by external environmental interference, which will affect the cutting quality. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-7 As shown, the present invention provides a laser cutting head structure for a long stroke, including a laser 1, a first reflecting mirror 11 for receiving the laser beam emitted by the laser 1, a second reflecting mirror 12 for receiving the laser beam reflected by the first reflecting mirror 11, a laser head 13 for receiving the laser beam reflected by the second reflecting mirror 12, a first drive motor 14, a housing 2, a first slide rail 3, a mounting plate 4, and a first rack 5.

[0024] The housing 2 is slidably mounted on the cutting platform 6. The housing 2 contains a receiving cavity, and the bottom wall of the receiving cavity has an elongated slot along a first direction. The laser 1 is positioned on one side of the bottom wall of the receiving cavity along the first direction. It should be understood that the two ends of the cutting platform 6 have sliding tracks along their length, and the housing 2 is slidably mounted on these sliding tracks.

[0025] Preferably, the laser is elongated.

[0026] The first slide rail 3 is disposed on the other side of the bottom wall of the receiving cavity along the first direction, wherein a first slider 31 is slidably disposed in the first slide rail 3. That is to say, the first slide rail 3 and the laser 1 are respectively disposed on both sides of the bottom wall of the receiving cavity.

[0027] The mounting plate 4 is connected to the first slider 31 and is slidably mounted on the first slide rail 3 via the first slider 31. The laser head 13 and the first drive motor 14 are mounted on the mounting plate 4, and the laser head 13 is located in the slotted hole. That is to say, the laser beam emitted by the laser head 13 is emitted from the slotted hole.

[0028] It is understood that the laser beam emitted by laser 1 is reflected by the first reflector 11 to the second reflector 12, and then directed by the second reflector 12 to the laser head 13 (that is, the laser head 13 also has a reflector that emits the laser beam downwards). The laser output end of the laser head 13 is facing the cutting platform 6. The sliding of the housing 2 on the cutting platform 6 allows the object to be cut on the cutting platform 6 to remain in place without moving. The laser cutting of the object can be completed by moving the housing 2. The housing 2 slides on the cutting platform 6 along the second direction, while the laser head 13 slides on the first slide rail 3 along the first direction via the mounting plate 4. The first and second directions are perpendicular to each other, so that the object to be cut on the cutting platform 6 can be cut.

[0029] The first rack 5 is disposed on the bottom wall of the receiving cavity along the first direction, wherein the rotating shaft of the first drive motor 14 is provided with a first gear 51 that meshes with the first rack 5. It should be understood that when the first drive motor 14 rotates forward, the mounting plate 4 slides to one side along the first direction via the first slide rail 3, and when the first drive motor 14 rotates in reverse, the mounting plate 4 slides to the other side along the first direction via the first slide rail 3 (that is, slides back to the initial position). In other words, the power for the sliding of the laser head 13 comes from the first drive motor 14.

[0030] In this embodiment, the first reflector 11 and the second reflector 12 are spaced apart on both sides of one end of the bottom wall of the receiving cavity. It should be understood that by placing the laser 1, the first reflector 11, the second reflector 12, and the laser head 13 all within the receiving cavity of the housing 12, the optical path length of the laser is fixed and the laser travel is short, reducing losses during laser transmission and preventing external environmental interference with the laser optical path, thereby ensuring the quality of laser cutting.

[0031] Preferably, the first rack 5 is disposed between the laser 1 and the first slide rail 3.

[0032] In this embodiment, a plurality of mounting brackets 21 are spaced apart along a first direction on one side of the bottom wall of the receiving cavity. The laser 1 is mounted in the plurality of mounting brackets 21, thereby preventing the laser 1 from falling off when the housing 2 slides on the cutting platform 6, and also ensuring that the laser 1 does not jitter when outputting, avoiding deviation of the output laser direction. Preferably, the mounting brackets 21 are made of elastic material, such as silicone.

[0033] Furthermore, the first slide rail 3 is disposed on the side wall of the slotted hole along the first direction, wherein the mounting plate 4 includes a vertical plate 41 and a horizontal plate 42 perpendicularly connected to the vertical plate 41, and the vertical plate 41 is connected to the first slider 31. The laser head 13 is disposed in the vertical plate 41, and the first drive motor 14 is disposed in the horizontal plate 42. It should be understood that the vertical plate 41 is located within the slotted hole to drive the laser head 13 to slide within the slotted hole.

[0034] In this embodiment, the housing 2 is rectangular. A first door 23 is rotatably mounted on one side of the housing 2 via a first hinge 22, and a second door 25 is rotatably mounted on the other side of the housing 2 via a second hinge 24. Both the first door 23 and / or the second door 25 are equipped with handles. It should be understood that the laser 1 is located below the first door 23, and the laser head 13 is located below the second door 25. Opening the first door 23 and / or the second door 25 via the handles allows for viewing and maintenance of the laser 1 or the laser head 13. Furthermore, in some embodiments, the bottom wall of the housing 2's receiving cavity is covered with a first magnet layer, while the first door 23 has a second magnet layer attracted to the first magnet layer, and the second door 25 has a third magnet layer attracted to the second magnet layer.

[0035] Furthermore, the two ends of the housing 2 are respectively provided with a first extension 26 and a second extension 27 extending downwards. A second slider 261 is provided on the side of the first extension 26 facing the second extension 27, and a third slider 271 is provided on the side of the second extension 27 facing the first extension 26. It should be understood that the second slider 261 and the third slider 271 are slidably mounted on the sliding tracks at both ends of the cutting platform 6.

[0036] Furthermore, a second drive motor is provided in the first extension 26, and a third drive motor is provided in the second extension 27. A second gear 262 is provided on the side of the first extension 26 facing the second extension 27, and a third gear 272 is provided on the side of the second extension 27 facing the first extension 26. The rotating shaft of the second drive motor is connected to the second gear 262, and the rotating shaft of the third drive motor is connected to the third gear 272, allowing the second and third drive motors to simultaneously drive the second gear 262 and the third gear 272 to rotate. It should be understood that the two ends of the cutting platform 6 are respectively provided with a second rack and a third rack along their length direction, with the second gear 262 meshing on the second rack and the third gear 272 meshing on the third rack.

[0037] It is worth noting that the laser 1, laser head 13, first reflector 11, second reflector 12, first drive motor 14, second drive motor and third drive motor of this application can all be implemented using products in the prior art, and their principles and structures will not be described in detail here.
