Preferred embodiments of this application are shown in the drawings. However, this application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] In this application, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. It should be noted that the directions involved in this application—the first direction y, the second direction z, and the third direction x—are mutually perpendicular in space, and the first direction y, the second direction z, and the third direction x are parallel to the y-axis, z-axis, and x-axis directions in the spatial coordinate system, respectively.

[0033] Example:

[0034] In a first aspect, embodiments of this application provide a laser head module, see [link to relevant documentation]. Figures 1 to 3 As shown, it includes a slider 1 with a mounting plate 11 and a laser processing head 2 disposed on the slider 1. The slider 1 is configured to drive the laser processing head 2 to move in a second direction z. The laser processing head 2 is detachably connected to the mounting plate 11 via a first switching assembly 3. The first switching assembly 3 includes a first mating connection structure 31 and a first locking mechanism 32. The laser processing head 2 is connected to the mounting plate 11 via the first mating connection structure 31. The first locking mechanism 32 is disposed between the mounting plate 11 and the laser processing head 2. The first locking mechanism 32 is configured to move relative to the mounting plate 11 in a first direction y. When the first locking mechanism 32 moves to abut against the laser processing head 2, it locks the laser processing head 2.

[0035] The laser head module described in this application, through the setting of the first switching component 3, allows the laser processing head 2 to be detachably connected to the slider 1. In use, different processing modes can be achieved by replacing different laser processing heads 2 on the same machine tool. This multi-functional integration within the same laser head module enhances its applicability and, consequently, improves the working efficiency and applicability of the laser processing equipment. When installing the laser processing head 2, it is connected to the mounting plate 11 via the first mating connection structure 31, achieving initial fixation between them. Then, the first locking mechanism 32 abuts against the laser processing head 2, limiting its position. This simple mechanical structure enables rapid installation and removal of the laser processing head 2 from the slider 1, achieving mutual locking between the laser processing head 2 and the mounting plate 11. This prevents relative displacement between the laser processing head 2 and the mounting plate 11, improves the stability of the laser processing head 2 installation, and ensures the reliability of the laser processing head 2.

[0036] See Figures 4 to 7 As shown, optionally, the first locking mechanism 32 includes a connecting post 321 vertically disposed on the mounting plate 11 and a locking member 322 sleeved on the connecting post 321. The locking member 322 is provided with a mounting hole 3221 through which the connecting post 321 passes. The locking member 322 includes a handle 3222 and a connecting block 3224 arranged sequentially along the axial direction of the connecting post 321. The handle 3222 is disposed close to the mounting plate 11. An elastic connector 3225 is provided between the handle 3222 and the connecting block 3224. The elastic connector 3225 is sleeved on the connecting post 321. The two ends of the elastic connector 3225 are respectively connected to the connecting post 321 and the handle 3222. A second mating connection structure 323 is provided between the handle 3222 and the mounting plate 11.

[0037] The second mating connection structure 323 includes a limiting protrusion 3231 and a first limiting groove 3232 that mates with the limiting protrusion 3231. One of the handle 3222 and the mounting plate 11 has the limiting protrusion 3231, and the other has the first limiting groove 3232. When the handle 3222 swings to the point where the limiting protrusion 3231 engages with the first limiting groove 3232, the handle 3222 is positioned closer to the mounting plate 11, causing the locking member 322 to move away from the locking plate 11. The laser processing head 2 is positioned such that the connecting block 3224 is positioned away from the laser processing head 2 to release the laser processing head 2; when the handle 3222 swings to the point that the limiting protrusion 3231 disengages from the first limiting groove 3232, the handle 3222 is positioned away from the mounting plate 11, and the locking member 322 is positioned away from the mounting plate 11 as a whole, thereby causing the connecting block 3224 to move close to the laser processing head 2 to press against the laser processing head 2 and lock the laser processing head 2. Optionally, in some embodiments, the limiting protrusion 3231 is a hemispherical protrusion, and the first limiting groove 3232 is a hemispherical groove that cooperates with the limiting protrusion 3231. The cooperation between the limiting protrusion 3231 and the first limiting groove 3232 reduces the resistance between the two when the limiting protrusion 3231 is placed in the first limiting groove 3232, improves the smoothness of operation, and avoids mutual damage between the handle 3222 and the mounting plate 11.

[0038] See Figure 8As shown, in some embodiments, the second mating connection structure 323 further includes a second limiting groove 3233, the depth of which is less than the depth of the first limiting groove 3232. When the limiting protrusion 3231 is mated with the first limiting groove 3232, the handle 3222 is positioned away from the laser processing head 2, and the locking member 322 is also positioned away from the laser processing head 2. The second limiting groove 3233 limits the rotation of the handle 3222, facilitating precise control of the rotation of the handle 3222. When the limiting protrusion 3231 is mated with the second limiting groove 3233, the handle 3222 is positioned close to the laser processing head 2, and the connecting block 3224 abuts against the laser processing head 2, thereby achieving mutual locking between the mounting plate 11 and the laser processing head 2. In some embodiments, the connecting post 321 is threadedly connected to the mounting plate 11. The end of the connecting post 321 away from the mounting plate 11 has an adjustment groove 3211 for inserting an installation wrench. In use, the installation wrench is inserted into the adjustment groove 3211, and rotating the wrench causes the connecting post 321 to rotate relative to the mounting plate 11, thereby installing the connecting post 321 onto the mounting plate 11. The end of the connecting post 321 away from the mounting plate 11 has a flange 3212 circumferentially arranged around the connecting post 321. The elastic connector 3225 is disposed between the flange 3212 and the handle 3222. The flange 3212 is configured to prevent the end of the elastic connector 3225 from being restricted. In use, the elastic connector 3225 applies forces to both ends of the elastic connector 3225 and the handle 3222 respectively. The connecting post 321 is fixed on the mounting plate 11. The elastic connector 3225 applies a driving force to the handle 3222 to move closer to the mounting plate 11, so that the handle 3222 and the locking member 322 tend to move closer to the mounting plate 11. In use, swinging the cantilever 32222 causes the main body 32221 to rotate around the axis of the connecting post 321. When the cantilever 32222 rotates to the point where the limiting protrusion 3231 engages with the first limiting groove 3232, the handle 3222 is positioned close to the mounting plate 11, thereby causing the locking member 322 to be positioned close to the mounting plate 11 as a whole, and causing the connecting block 3224 to be positioned away from the laser processing head 2, so as to release the laser processing head 2. When the cantilever 32222 rotates to the point where the limiting protrusion 3231 disengages from the first limiting groove 3232, the handle 3222 is positioned away from the mounting plate 11, thereby causing the locking member 322 to be positioned away from the mounting plate 11 as a whole, and causing the connecting block 3224 to move close to the laser processing head 2 and abut against the laser processing head 2, so as to lock the laser processing head 2.

[0039] See Figure 7 As shown, the handle 3222 includes a main body 32221 sleeved on the connecting post 321 and a cantilever 32222 extending from the main body 32221 to the first mating connection structure 31. The first mating connection structure 31 has a clearance opening 313 for the cantilever 32222 to pass through, and the cantilever 32222 swings within the area of ​​the clearance opening 313.

[0040] Optional, see Figure 3 As shown, the first mating connection structure 31 includes a mounting groove 311 disposed along the second direction z and a connecting protrusion 312 that mates with the mounting groove 311; wherein, one of the mounting plate 11 and the laser processing head 2 is provided with the mounting groove 311, and the other is provided with the connecting protrusion 312. The first mating connection structure 31 is configured as a mating mounting groove 311 and a connecting protrusion 312 structure, which ensures that the laser processing head 2 is mounted on the mounting plate 11 while guiding and limiting the movement of the laser processing head 2 relative to the mounting plate 11.

[0041] Optional, see Figure 3 and Figure 11 As shown, the first locking mechanism 32 is located within the area enclosed by the first mating connection structure 31. The laser processing head 2 is provided with a guide groove 21, which extends along the second direction z. The connecting post 321 can move within the guide groove 21. That is, the guide groove 21 guides and avoids the movement of the connecting post 321, preventing the laser processing head 2 from interfering with the movement of the connecting post 321 when the end of the connecting post 321 protrudes from the plane of the connecting block 3224. This ensures the smooth operation of the laser head module and avoids mutual damage between components.

[0042] In some embodiments, see Figure 11 As shown, the guide groove 21 includes a closed end and an open end. The closed end is located near the top of the laser processing head 2, and the open end extends to the bottom of the laser processing head 2. In use, the top of the guide groove 21 is the closed end. When the laser processing head 2 is moved into position, the closed end of the guide groove 21 limits the output end of the first locking mechanism 32, preventing relative movement between the first locking mechanism 32 and the laser processing head 2, further improving the locking stability of the first locking mechanism 32 and the installation stability of the laser processing head 2.

[0043] Optional, see Figure 1 , Figure 9 and Figure 10As shown, the laser head module also includes a cooling system 4, which is configured to cool the laser processing head 2. The cooling system 4 includes a first housing 41, a second housing 42, and a cooling pipe 43. The cooling pipe 43 is connected to the second housing 42, and the first housing 41 is fixedly connected to the laser processing head 2. The first housing 41 is detachably connected to the second housing 42 via a second switching assembly 5. The detachable connection between the cooling system 4 and the laser processing head 2 through the detachable connection between the first housing 41 and the second housing 42 ensures smooth switching of the laser processing head 2.

[0044] Optionally, the second switching component 5 includes a third mating connection structure 51 and a second locking mechanism 52; the third mating connection structure 51 includes a locking block 511 and a locking groove 512, one of the first housing 41 and the second housing 42 is provided with the locking block 511, and the other is provided with the locking groove 512; the second locking mechanism 52 is configured to limit the first housing 41 and the second housing 42 in the second direction z; the second locking mechanism 52 includes a second connecting post 521 provided on the second housing 42, a knob 522 sleeved on the second connecting post 521, and an elastic reset member 523 connecting the second connecting post 521 and the knob 522, the knob 522 extends from the second housing 42 to the first housing 41, the first housing 41 is provided with an insertion hole 411 for the knob 522 to be inserted, when the first housing 41 is connected to the second housing 42, the knob 522 is inserted into the insertion hole 411, and the second housing 42 is provided with a second clearance hole 421 exposing the knob 522.

[0045] In use, the first housing 41 is assembled to the second housing 42 along the second direction z, such that the locking block 511 is engaged with the locking slot 512. During assembly, pressing the knob 522 causes the elastic reset member 523 to apply force to the knob. After the first housing 41 is assembled to the second housing 42, the knob 522 is released. Under the action of the elastic reset member 523, the knob 522 rotates in the opposite direction and is inserted into the insertion hole 411, thereby locking the first housing 41 and the second housing 42 in the second direction z. The combined cooperation of the third mating connection structure 51 and the second locking mechanism 52 ensures the stability of the connection between the first housing 41 and the second housing 42.

[0046] The second housing 42 is provided with a limiting post 422 arranged along the second direction z. The limiting post 422 is configured to limit the rotation angle of the knob 522. The setting of the limiting post 422 avoids the excessive force of the elastic reset member 523 caused by the excessive rotation angle of the knob 522, which affects the durability and operational stability of the elastic reset member 523.

[0047] Optional, see Figure 1 As shown, the slider 1 includes a transmission bearing 12 disposed along a third direction x, the transmission bearing 12 being configured to drive the laser processing head 2 to move along the third direction x. Optionally, in some embodiments, the number of transmission bearings 12 is two, respectively distributed along the second direction z, the arrangement of the transmission bearings 12 ensuring the stability of the laser head module's movement along the third direction x.

[0048] Secondly, embodiments of this application provide a laser processing device, which includes the laser head module as described above.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
