[0021] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0022] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0023] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0024] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0025] Reference Figure 1 and Figure 2 The utility model provides a flexible laser head, including a laser head body 1, a fixing seat 2, and an adjustment component 3. The laser head body 1 and the adjustment component 3 are located above the fixing seat 2. The fixing seat 2 is used to be fixed on the equipment. The adjustment component 3 can adjust the emission angle of the laser head body 1. The internal structure of the laser head body 1 is the existing technology and will not be repeated in this application.

[0026] The fixed seat 2 is a plate, and the adjustment component 3 includes a turntable 31, a gear 32, and a rack 33. The turntable 31 and the gear 32 are coaxially arranged, the turntable 31 is fixed to the upper side of the gear 32, and the gear 32 is rotatably connected to the top of the fixed seat 2. Two vertical beams 34 are fixed above the turntable 31, and the laser head body 1 is rotatably connected between the two vertical beams 34. When the gear 32 rotates, it can drive the turntable 31 to rotate, thereby driving the laser to have a rotation direction.

[0027] A servo motor 341 is fixed to the side wall of the vertical beam 34, and the output shaft of the servo motor 341 is fixed to the rotating shaft connecting the laser head body 1 and the vertical beam 34. When working, the output shaft of the servo motor 341 rotates to drive the laser head body 1 to rotate, thereby making the end of the laser head swing up and down.

[0028] When adjusting the angle of the laser head, the gear 32 can rotate to drive the turntable 31 to rotate, and the rotation of the turntable 31 drives the laser head body 1 to rotate horizontally, and then the servo motor 341 is used to adjust the angle of the laser head on the vertical plane, so that the laser head can flexibly adjust the emission angle at multiple angles to meet complex laser cutting requirements.

[0029] As an embodiment, a rack 33 is connected to the fixed seat 2 in a sliding direction in the horizontal direction, and the rack 33 is meshed with the gear 32. When the rack 33 slides, it can drive the gear 32 to rotate. A drive cylinder 35 is fixed to the fixed seat 2. The drive cylinder 35 is located on one side of the rack 33. The length direction of the drive cylinder 35 is the same as the sliding direction of the rack 33. A connecting block 351 is fixed to one end of the rack 33. The drive cylinder 35 is also fixed to the telescopic rod and the connecting block 351. When the drive cylinder 35 is working, the telescopic rod of the drive cylinder 35 can drive the connecting block 351 to slide. The connecting block 351 is connected to the rack 33 and slides back and forth in the horizontal direction, thereby driving the gear 32 to rotate and quickly adjust the position of the laser head. It should be noted that the driving structure that drives the gear 32 to rotate is not necessarily the rack 33, but can also be other gears 32 meshed with it. It is just that the rack 33 and the drive cylinder 35 are used for driving, which is convenient for arranging positions and saves space.

[0030] As an embodiment, the flexible laser head includes a limit assembly 4, which can position the rotation of the turntable 31. The limit assembly 4 includes a magnetic ring 41 and an electromagnet 42. The magnetic ring 41 is fixed above the turntable 31, and the magnetic ring 41 is coaxially arranged with the turntable 31. A support plate 43 is fixed on the fixed seat 2, and a plane plate 44 is fixed on the upper end of the support plate 43. One side of the plane plate 44 extends to the upper side of the turntable 31. The electromagnet 42 is fixed on the lower side of the plane plate 44, and the electromagnet 42 is in contact with the magnetic ring 41. When the electromagnet 42 is not energized, the magnetic ring 41 can rotate with the turntable 31 under the electromagnet 42 to adjust the direction of the laser head. When the laser head stops, the electromagnet 42 is energized to absorb the magnetic ring 41 and position the magnetic ring 41, so as to position the laser head body 1, avoid the gap between the gear 32 and the rack 33 causing a small swing of the laser head body 1, and improve the position accuracy of the laser head body 1.

[0031] As an embodiment, the side of the electromagnet 42 away from the support plate 43 is located on the upper side of the magnetic ring 41, so that the side of the electromagnet 42 does not exceed the inner circumference of the magnetic ring 41, and the electromagnet 42 and the rotating vertical beam 34 interfere with each other, so that the laser head body 1 can rotate normally.

[0032] The implementation principle of the utility model is: when adjusting the angle of the laser head, the gear 32 can rotate to drive the turntable 31 to rotate, and the rotation of the turntable 31 drives the laser head body 1 to rotate horizontally, and then the servo motor 341 is used to adjust the angle of the laser head on the vertical plane, so that the laser head can flexibly adjust the emission angle at multiple angles, which can meet complex laser cutting needs.

[0033] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0034] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
