[0029] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the laser cutting mechanism, equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] See Figure 1The laser cutting mechanism includes a laser cutting head 100 and a protective component 200.

[0034] The laser cutting head 100 is used to emit laser light through the light output hole 110. It can be understood that the laser light emitted through the light output hole 110 can cut the workpiece.

[0035] The protective component 200 includes a protective element 210, which is disposed at least around the light outlet 110 of the laser cutting head 100 and is connected to the laser cutting head 100.

[0036] It is understandable that the laser cutting head 100 is generally close to the workpiece when cutting it. Therefore, the protective component 210 is set around the light outlet hole 110 of the laser cutting head 100 at least. This can block the spatter generated during the laser cutting process and also serve to shield the light.

[0037] In addition, since the protective component 210 is directly connected to the laser cutting head 100, the protective component 210 can move with the position of the laser cutting head 100, thereby always shielding the spatter during the laser cutting process.

[0038] In other words, the laser cutting mechanism of this application is provided with a protective component 210, and the protective component 210 is arranged at least around the light emission hole 110 of the laser cutting head 100. In this way, when the laser emitted through the light emission hole 110 cuts the workpiece, the protective component 210 can block the spatter generated during the cutting process, prevent the spatter from damaging the surrounding objects, and the protective component 210 can also play a role in blocking light.

[0039] In addition, the protective component 210 can be connected to the laser cutting head 100, so that the protective component 210 can move with the laser cutting head 100 to ensure that it can always block the spatter generated when the laser cutting head 100 cuts the workpiece.

[0040] Further, see Figure 3 The cutting range 120 of the laser emitted by the laser cutting head 100 is within the protective range formed by the protective component 210.

[0041] For example, the protective area formed by the protective element 210 can cover the laser cutting range 120.

[0042] Understandably, in one embodiment, a galvanometer is provided inside the laser cutting head 100. The galvanometer can deflect the laser along a preset path, that is, the laser emitted from the light outlet 110 can be deflected within a certain range, so that the laser emitted by the laser cutting head 100 can have a certain cutting range 120. Therefore, the cutting range 120 of the laser emitted by the laser cutting head 100 is within the protective range formed by the protective member 210, and interference between the laser and the protective member 210 can be avoided.

[0043] Furthermore, the protective component 210 may protrude from the light-emitting hole 110 in the axial direction of the light-emitting hole 110. It can be understood that the above method allows the protective component 210 to be closer to the workpiece or to contact the workpiece without causing the laser cutting head 100 to collide with the workpiece, thereby avoiding an excessive gap between the protective component 210 and the workpiece that would affect the material blocking and light-shielding effects.

[0044] Preferably, in one embodiment, the protective member 210 may be made of a flexible material. It is understood that a flexible material protective member 210 can prevent rigid contact between the protective member 210 and the workpiece.

[0045] Further, see Figure 4 The protective component 210 may include multiple independently movable shielding parts 211 along the circumferential direction.

[0046] It is understandable that multiple independently movable shielding parts 211 can move separately when in contact with the workpiece, avoiding interference between the shielding parts 211. This structure is beneficial for the protective part 210 to be applicable to workpieces of different shapes.

[0047] Furthermore, the protective component 210 may also include a main body 212, which is arranged around the laser cutting head 100. Multiple shielding parts 211 are sequentially connected to the main body 212 along the surrounding direction of the main body 212. This method facilitates the connection of multiple independently movable shielding parts 211 to the laser cutting head 100.

[0048] For example, in one embodiment, the protective element 210 may be a plastic curtain.

[0049] See Figure 5 The protective component 200 may further include a connector 220, which surrounds the laser cutting head 100. The protective component 210 is connected to the connector 220, and the connector 220 is connected to the laser cutting head 100. It is understood that in one embodiment, the protective component 210 may be made of a flexible material. Therefore, providing the connector 220 facilitates the flexible material protective component 210 surrounding the laser cutting head 100 and connecting to it.

[0050] Furthermore, in order to reduce the obstruction of other parts of the laser cutting head 100 by the connector 220, and to facilitate the connection of the connector 220 to the laser cutting head 100, the connector 220 may include a first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 is arranged around the laser cutting head 100, and the protective member 210 is connected to the first connecting portion 221. One end of the second connecting portion 222 is connected to the first connecting portion 221, and the other end of the second connecting portion 222 extends away from the protective member 210 and is connected to the laser cutting head 100.

[0051] See Figure 6 This application also provides a laser cutting device, including a drive mechanism 300, a mounting component, and the laser cutting mechanism in the embodiment. The laser cutting head 100 and the protective component 210 are connected to the mounting component, and the drive mechanism 300 is drivenly connected to the mounting component so that the mounting component can drive the laser cutting head 100 and the protective component 210 to move synchronously.

[0052] It is understandable that the aforementioned laser cutting equipment can move the laser cutting head 100 simultaneously and move the protective component 210 at the same time, and can facilitate the connection of the protective component 210 to avoid damage to the laser cutting head 100.

[0053] In one embodiment, the laser cutting equipment further includes a base 400 and a sensor 500. The drive mechanism 300 is disposed on the base 400, and the sensor 500 is located on the periphery of the laser cutting head 100 and mounted on the base 400.

[0054] When the laser cutting equipment of this application is equipped with a sensor 500, the protective component 210 can prevent the sensor 500 from being damaged by spatter generated during the laser cutting process.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
