[0049] Laser processing equipment, such as laser engraving machines and laser marking machines, which utilize lasers to achieve processing purposes, is becoming increasingly popular. During laser processing, the laser head that emits the laser generates a significant amount of heat. In related technologies, liquid cooling channels are often incorporated into the laser head to improve its heat dissipation efficiency. However, the installation process typically involves first fixing the laser head to a mounting base, and then connecting the water pipes to the water connectors on the liquid cooling channels, making the installation steps cumbersome.

[0050] To address the aforementioned problems, this invention proposes a laser head module 100 for use in laser processing equipment. The laser head module 100 emits laser light to perform laser processing operations such as laser marking, laser engraving, laser cutting, and laser welding on the processed materials. The laser processing equipment also includes a main body, which comprises a frame and a motion assembly mounted on the frame. A processing platform for supporting the processed materials is located within the frame. The laser head module 100 is mounted on the motion assembly and positioned above the processing platform. The laser head module 100 can be driven by the motion assembly to move to different positions on the processing platform for laser processing.

[0051] See also Figures 1 to 5 as well as Figure 7In one embodiment of this utility model, the laser head module 100 includes a laser head 10 and a mounting base 20. The laser head 10 is provided with a liquid cooling channel and has a first liquid inlet connector 13 and a first liquid outlet connector 19 that are respectively connected to the two ends of the liquid cooling channel. The mounting base 20 is provided with a liquid inlet channel 221 and a liquid outlet channel 224, and has a second liquid inlet connector 23 that is connected to the liquid inlet channel 221 and a second liquid outlet connector 27 that is connected to the liquid outlet channel 224. The laser head 10 is mounted on the mounting base 20. The first liquid inlet connector 13 and the second liquid inlet connector 23 are inserted and connected along the first direction X. The first liquid outlet connector 19 and the second liquid outlet connector 27 are inserted and connected along the first direction X.

[0052] Specifically, the laser head 10 in the laser head module 100 serves as a functional structure for emitting laser light and includes a laser module 12 for generating laser light. The laser module 12 can be, but is not limited to, a semiconductor laser, a solid-state laser, a gas laser, or a free-electron laser. Optionally, the laser head 10 may also include a mounting bracket 11 for supporting the laser module 12. The laser head 10 has a liquid-cooling channel for coolant flow. This channel can be located within the laser module 12 or within a liquid-cooling structure in contact with the laser module 12, with the liquid-cooling channel within the liquid-cooling structure. The liquid-cooling channel has two ends: an inlet and an outlet. In practical applications, coolant flows into the liquid-cooling channel from the inlet, exchanges heat with the laser head 10, and then flows out from the outlet, thus carrying away heat from the laser head 10 and dissipating heat.

[0053] The mounting base 20 in the laser head module 100 is used to mount the laser head 10. The mounting base 20 can be configured as, but is not limited to, a plate-like structure, a frame structure, a shell structure, or other shapes. The mounting base 20 can be configured to support the laser head 10 from below, or it can be positioned to the side or above the laser head 10, allowing the laser head 10 to be hung on the mounting base 20. When the laser head module 100 is used in laser processing equipment, the mounting base 20 is fixed in the module mounting position of the laser head module 100 in the laser processing equipment, for example, mounted on a motion component; or mounted on a lifting component of the motion component; the laser head 10 is fixed in the laser processing equipment by mounting the laser head 10 on the mounting base 20.

[0054] The mounting base 20 is provided with a liquid inlet channel 221 and a liquid outlet channel 224. One end of the liquid inlet channel 221 is connected to the liquid inlet end of the liquid cooling channel, and the other end is used to connect to the liquid cooling system. One end of the liquid outlet channel 224 is connected to the liquid outlet end of the liquid cooling channel, and the other end is used to connect to the liquid cooling system, so that the coolant can circulate between the laser module 12 and the liquid cooling system. Optionally, the other end of the liquid inlet channel 221 and the liquid outlet channel 224 can be connected to a water pipe connector 25 for connecting a water pipe connected to the liquid cooling system.

[0055] In this embodiment, the two ends of the liquid cooling channel are respectively connected to a first liquid inlet connector 13 and a first liquid outlet connector 19. The end of the liquid inlet channel 221 used to communicate with the liquid cooling channel is connected to a second liquid inlet connector 23. The first liquid inlet connector 13 is configured as one of a male plug and a female socket, and the second liquid inlet connector 23 is the other of a male plug and a female socket. When the laser head 10 is installed on the mounting base 20, the first liquid inlet connector 13 and the second liquid inlet connector 23 are plugged in and engaged, thereby connecting the liquid inlet channel 221 with the liquid cooling channel. There is no need to perform separate operations to fix the laser head 10 and connect the liquid inlet channel 221 with the liquid cooling channel. When it is necessary to remove the laser head 10, there is no need to perform an additional operation to disconnect the liquid inlet channel 221 from the liquid cooling channel, thus improving the convenience of disassembly and assembly of the laser module 12.

[0056] The liquid outlet channel 224 is connected to a second liquid outlet connector 27 at one end, which is used to communicate with the liquid cooling channel. The first liquid outlet connector 19 is configured as one of a male plug and a female socket, and the second liquid outlet connector 27 is the other of a male plug and a female socket. When the laser head 10 is installed on the mounting base 20, the first liquid outlet connector 19 and the second liquid outlet connector 27 are plugged in and engaged, thereby connecting the liquid outlet channel 224 with the liquid cooling channel. There is no need to perform separate operations to fix the laser head 10 and connect the liquid outlet channel 224 with the liquid cooling channel. When the laser head 10 needs to be removed, there is no need to perform an additional operation to disconnect the liquid outlet channel 224 from the liquid cooling channel. Furthermore, the docking direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the docking direction of the first liquid outlet connector 19 and the second liquid outlet connector 27, are all in the first direction X. When the laser head 10 is installed on the mounting base 20, the first liquid inlet connector 13 and the second liquid inlet connector 23 can be docked at the same time as the first liquid outlet connector 19 and the second liquid outlet connector 27, which improves the convenience of disassembling and assembling the laser module 12.

[0057] That is, in the technical solution of this application, the laser head module 100 includes a laser head 10 and a mounting base 20 for mounting the laser head 10; when the laser head module 100 is applied to a laser processing equipment, the mounting base 20 is fixed to the main body of the laser processing equipment, the liquid inlet channel 221 and the liquid outlet channel 224 in the mounting base 20 are connected to the liquid cooling system, and when the laser head 10 is mounted on the mounting base 20, the first liquid inlet connector 13 in the laser head 10 connected to the liquid cooling channel aligns with the second liquid inlet connector in the mounting base 20 connected to the liquid inlet channel 221. 23. The first liquid outlet connector 19 is connected to the second liquid outlet connector 27 in the mounting base, which is connected to the liquid outlet channel 224. This allows the liquid cooling channel to be connected to the liquid cooling system through the liquid inlet channel 221 and the liquid outlet channel 224. This eliminates the need to connect the laser module 12 and the liquid cooling system after fixing the laser head 10. When it is necessary to remove the laser head 10, the laser head 10 can be removed from the mounting base 20 without the need to disconnect the liquid cooling channel from the liquid inlet channel 221 and the liquid outlet channel 224. This improves the ease of disassembling and assembling the laser head 10.

[0058] Please see Figure 4 and Figure 5 In one embodiment, the laser head 10 includes a first connecting portion 154, and the mounting base 20 includes a second connecting portion 213. The first connecting portion 154 is connected to the second connecting portion 213. The connection direction of the first connecting portion 154 and the second connecting portion 213 is a first direction X.

[0059] In this embodiment, the first connecting part 154 and the second connecting part 213 can be connected to each other by means of snap-fit ​​connection, bolt fastening, or magnetic attraction to connect the laser head 10 to the mounting base 20. For example, the first connecting part 154 can be configured as a first snap-fit ​​part, and the second connecting part 213 can be configured as a first snap-fit ​​part, with the first snap-fit ​​part and the second snap-fit ​​part engaging along the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23; or, the first connecting part 154 and the second connecting part 213 can be configured as a first magnetic attraction part and a second magnetic attraction part arranged opposite to each other along the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, so as to engage with each other magnetically; or, the first connecting part 154 and the second connecting part 213 can be configured as a coaxial first connecting hole 1541 and a second connecting hole 2131 as in the following embodiment, and connected by a bolt or other connecting member 30.

[0060] This configuration ensures a stable connection between the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as a stable connection between the first liquid outlet connector 19 and the second liquid outlet connector 27. It also prevents the first liquid inlet connector 13 and the second liquid inlet connector 23 from being squeezed together in the non-insertion direction when fixing the laser module 12 due to the direction of the connecting force intersecting with the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23. This avoids damage to the first liquid inlet connector 13 and the second liquid inlet connector 23 and ensures a sealed connection between them, preventing leakage. Similarly, it avoids the first liquid outlet connector 19 and the second liquid outlet connector 27 from being squeezed together in the non-insertion direction when fixing the laser module 12, preventing damage to the first liquid outlet connector 19 and the second liquid outlet connector 27 and ensuring a sealed connection, preventing leakage.

[0061] Please see Figure 4 and Figure 5 In one embodiment, the first connecting part 154 is the first connecting hole 1541, the second connecting part 213 is the second connecting hole 2131, and the laser head module 100 also includes a connector 30. Along the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, the connector 30 passes through the first connecting hole 1541 and the second connecting hole 2131 to connect the laser head 10 and the mounting base 20.

[0062] In this embodiment, the first connecting portion 154 and the second connecting portion 213 are configured as a first connecting hole 1541 and a second connecting hole 2131 arranged coaxially. The axial direction of the first connecting hole 1541 and the second connecting hole 2131 is parallel to the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23. Alternatively, one of the first connecting hole 1541 and the second connecting hole 2131 can be configured as a threaded hole, and a bolt can be used as the connecting member 30. The bolt passes through the first connecting hole 1541 and the second connecting hole 2131 and is threadedly connected to the threaded hole therein to connect the laser head 10 and the mounting base 20. Alternatively, both the first connecting hole 1541 and the second connecting hole 2131 can be configured as through holes, and the connecting member 30 can be configured as a rivet, or the connecting member 30 can be configured as a bolt, with a nut providing a connection and engagement with the bolt.

[0063] Please see Figure 4 and Figure 5 In one embodiment, the laser head 10 includes a mounting bracket 11 and a laser module 12. The mounting bracket 11 is connected to the mounting base 20. The laser module 12 is mounted on the mounting bracket 11. The laser module 12 is provided with a liquid cooling channel. The first liquid inlet connector 13 and the first liquid outlet connector 19 are connected to the laser module 12.

[0064] In this embodiment, the laser head 10 includes a laser module 12 for generating laser light and a mounting bracket 11 for mounting the laser module 12. The laser module 12 may be, but is not limited to, a semiconductor laser module 12, a solid-state laser module 12, a gas laser module 12, and a free-electron laser module 12. It can be understood that the laser module 12, as the functional structure for generating laser light, is also the main heat-generating structure of the laser head 10. By placing the liquid cooling channel in the laser module 12, the heat of the laser module 12 can be better dissipated, thus enabling better heat dissipation of the laser head 10.

[0065] The mounting bracket 11 is used to fix the laser module 12 and serves as a connection structure for connecting the laser head 10 to the mounting base 20. By connecting or separating the mounting bracket 11 from the mounting base 20, the laser head 10 can be fixed to or removed from the mounting base 20. This configuration eliminates the need for locking operations on the laser module 12 when installing or removing the laser head 10, reducing the risk of damage to the laser module 12 during installation or removal.

[0066] Optionally, the mounting bracket 11 may be, but is not limited to, a plate structure, a shell structure, a bearing seat, or other structural forms.

[0067] Please see Figure 4 and Figure 5 In one embodiment, the laser head 10 further includes a pad 18 located between the mounting bracket 11 and the laser module 12, such that at least a portion of the laser module 12 is spaced apart from the mounting bracket 11.

[0068] This arrangement creates a heat dissipation gap between the laser module 12 and the mounting bracket 11, which helps improve the heat dissipation efficiency of the laser module 12. Optionally, a single layer of pad 18 can be provided in the arrangement direction of the laser module 12 and the mounting bracket 11, or two or more layers of pads 18 can be stacked. In addition, each layer of pad 18 can be a single-piece structure, or it can be composed of multiple sub-pads 18 distributed in different areas.

[0069] See also Figures 1 to 3 as well as Figure 6 In one embodiment, the laser head 10 further includes a housing 14 covering the mounting bracket 11. The housing 14 and the mounting bracket 11 enclose a mounting cavity 1411. The housing 14 is provided with a first passage 1423, a second passage 1424, and a third passage 1426 communicating with the mounting cavity 1411. The laser module 12 is disposed in the mounting cavity 1411. The first liquid inlet connector 13 is disposed facing the first passage 1423, the light outlet of the laser module 12 is disposed facing the second passage 1424, and the first liquid outlet connector 19 is disposed facing the third passage 1426. At least a portion of the mounting base 20 is disposed opposite to the first passage 1423 and the third passage 1426 and abuts against the housing 14.

[0070] In this embodiment, the laser head 10 also includes a cover 14, which forms a mounting cavity 1411 with a first opening. The cover 14 is placed on the mounting bracket 11, and the first opening of the cover 14 faces the mounting bracket 11. The mounting bracket 11 closes the first opening, thereby forming a mounting cavity 1411 for mounting the laser module 12 by the cover 14 and the mounting bracket 11. This prevents the laser module 12 from being directly exposed to the outside world, thus protecting the laser module 12. The housing 14 has a first passage 1423 communicating with the mounting cavity 1411. The first passage 1423 is correspondingly arranged with the first liquid inlet connector 13, and the third passage 1426 is correspondingly arranged with the first liquid outlet connector 19. When the laser head 10 is installed with the mounting base 20, at least part of the mounting base 20 is located in the direction of the first passage 1423 and the third passage 1426 and abuts against the housing 14. The second liquid inlet connector 23 is arranged in the area opposite to the first passage 1423. The first liquid inlet connector 13 can extend from the first passage 1423 to mate with the second liquid inlet connector 23, or the second liquid inlet connector 23 can pass through the first passage 1423 to mate with the first liquid inlet connector 13. The first liquid outlet connector 19 is arranged in the area opposite to the third passage. The first liquid outlet connector 19 can extend from the third passage 1426 to mate with the second liquid outlet connector 27, or the second liquid outlet connector 27 can pass through the third passage 1426 to mate with the first liquid outlet connector 19. Optionally, the first port 1423 and the third port 1426 can be made independent of each other or connected.

[0071] The housing 14 is also provided with a second passage 1424 communicating with the mounting cavity 1411. The second passage 1424 is correspondingly arranged with the light output port of the laser module 12, so that the laser generated by the laser module 12 can be emitted outward from the second passage 1424 for laser processing. Optionally, the first passage 1423 and the third passage 1426 can be arranged on the same side of the housing 14 as the second passage 1424, or they can be arranged on different sides of the housing 14.

[0072] See also Figure 1 and Figure 6 In one embodiment, the cover 14 includes a shell body 141 and a bottom cover 142. The shell body 141 has a mounting cavity 1411 and a first opening and a second opening communicating with the mounting cavity 1411. The first opening and the second opening are located on adjacent sides of the shell body 141, and the first opening is disposed towards the mounting bracket 11. The bottom cover 142 covers the second opening, and at least a portion of the mounting seat 20 is located on the side of the bottom cover 142 away from the shell body 141. The bottom cover 142 includes a first portion 1421 that abuts against the mounting seat 20 and a second portion 1422 that is misaligned with the mounting seat 20. The first portion 1421 has a first passage 1423 and a third passage 1426, and the second portion 1422 has a second passage 1424.

[0073] In this embodiment, the housing 14 includes a housing body 141 and a bottom cover 142. The bottom cover 142 and the mounting bracket 11 are located on adjacent sides of the housing body 141. The mounting bracket 11 covers the first opening on the housing body 141, and the bottom cover 142 covers the second opening on the housing body 141. The light outlet, the first liquid inlet connector 13, and the first liquid outlet connector 19 of the laser module 12 all face the bottom cover 142. The first through port 1423, the third through port 1426, and the second through port 1424 are all provided on the bottom cover 142 of the housing 14. In some embodiments, a portion of the mounting base 20 can be disposed on the side of the bottom cover 142 opposite to the mounting cavity 1411. For example, in the embodiments described below, the mounting base 20 includes a base body 22 and a back plate 21. The base body 22 is disposed on the side of the bottom cover 142 opposite to the mounting cavity 1411, and the back plate 21 is disposed on the side of the mounting bracket 11 opposite to the mounting cavity 1411. In some embodiments, the entire mounting base 20 can also be disposed on the side of the bottom cover 142 opposite to the mounting cavity 1411. In this case, the cover 14 and the mounting base 20 can be located on the same side of the mounting bracket 11, and the mounting bracket 11 is connected to the mounting base 20.

[0074] In this embodiment, the mounting base 20 abuts against the first portion 1421 of the bottom cover 142, and the second liquid inlet connector 23 and the second liquid outlet connector 27 are correspondingly arranged with the first portion 1421 so that the first liquid inlet connector 13 and the second liquid inlet connector 23 can be inserted and engaged, and the first liquid outlet connector 19 and the second liquid outlet connector 27 can be inserted and engaged. The mounting base 20 and the second portion 1422 of the bottom cover 142 are misaligned to avoid the mounting base 20 from blocking the second passage 1424, thereby avoiding blocking the laser.

[0075] Optionally, the bottom cover 142 can be configured as a plate-like structure or a stepped structure. For example, in the embodiment below, the first part 1421 and the second part 1422 of the bottom cover 142 are distributed in a stepped manner.

[0076] Optionally, the housing body 141 and the bottom cover 142 can be detachably connected, and the housing body 141 can be removed separately to expose the structure in the laser module 12 and the mounting cavity 1411, which is convenient for disassembly and maintenance; and the housing body 141 can be disassembled and assembled separately while keeping the laser head 10 connected to the mounting base 20.

[0077] Please see Figures 2 to 5 In one embodiment, the mounting base 20 includes a base body 22 and a back plate 21 connected to each other. The base body 22 is located on one side of the laser head 10 along the first direction X, and the back plate 21 is located on one side of the laser head 10 along the second direction Y. The first direction X and the second direction Y intersect. At least one of the base body 22 and the back plate 21 is connected to the laser head 10.

[0078] In this embodiment, the base 22 and back plate 21 of the mounting base 20 abut against the laser head 10 in the first direction X and the second direction Y, respectively. This improves the stability and accuracy of the laser module 12 mounted on the mounting base 20, ensuring accurate docking of the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the accurate docking of the first liquid outlet connector 19 and the second liquid outlet connector 27. Taking the laser head 10 with its light emission direction vertically downward as an example, the second direction Y is parallel to the horizontal direction, and the back plate 21 is located to the side of the laser head 10. In this case, as shown in the illustrated embodiment, the first direction X can be vertical, so that the base 22 is located below the laser head 10 to support it, and the base 22 and the light emission area of ​​the laser head 10 are offset. Alternatively, the first direction X is parallel to the horizontal direction, and the base 22 is located to the side of the laser head 10.

[0079] In this embodiment, the back plate 21 can be connected to the laser head 10, the base 22 can be connected to the laser head 10, or both the back plate 21 and the base 22 can be connected to the laser head 10; no limitation is made here.

[0080] Please see Figure 5 and Figure 7 In one embodiment, the base 22 is provided with an inlet channel and an outlet channel, the second inlet connector 23 and the second outlet connector 27 are provided on the side of the base 22 facing the laser head 10, and the first inlet connector 13 and the first outlet connector 19 are provided on the side of the laser head 10 facing the base 22.

[0081] In this embodiment, the liquid inlet channel 221 and the liquid outlet channel 224 are arranged in the base body 22, and the second liquid inlet connector 23 and the second liquid outlet connector 27 are located on the side of the base body 22 facing the laser head 10. The laser head 10 can move along the first direction X on the surface of the back plate 21 to approach the base body 22, so that the laser head 10 abuts against the base body 22. At the same time, the first liquid inlet connector 13 and the second liquid inlet connector 23 are inserted and engaged, and the first liquid outlet connector 19 and the second liquid outlet connector 27 are inserted and engaged, which is simple to operate.

[0082] See also Figure 2 and Figure 3 In one embodiment, the laser head 10 is provided with a limiting structure 15 on one side along the second direction Y. The limiting structure 15 is provided with a limiting space 153 and a first clearance opening communicating with the limiting space 153. The first clearance opening is located on one side of the limiting space 153 along the first direction X. At least part of the back plate 21 is provided in the limiting space 153.

[0083] In this embodiment, the laser head 10 is provided with a limiting structure 15. The limiting structure 15 includes at least two first limiting members 151 spaced apart along the third direction Z. A limiting space 153 is formed between the two first limiting members 151, and a first clearance opening is provided at least at the end near the base 22 along the first direction X. The third direction Z is parallel to the surface of the back plate 21, and the first direction X, the second direction Y, and the third direction Z intersect each other. When the laser head 10 is installed on the mounting base 20, the laser head 10 moves along the first direction X to approach the base 22. At this time, the back plate 21 can be inserted into the limiting space 153 along the first clearance opening, so that the back plate 21 and the laser head 10 mutually limit each other in the third direction Z, thereby improving the connection strength between the laser head 10 and the mounting base 20. Furthermore, by utilizing the mutual cooperation of the limiting structure 15 and the back plate 21, the installation position and installation direction of the laser head 10 are guided and limited, ensuring that the first liquid inlet connector 13 and the second liquid inlet connector 23 are accurately inserted and engaged, and ensuring that the first liquid outlet connector 19 and the second liquid outlet connector 27 are inserted and engaged.

[0084] In some embodiments, the laser head 10 includes a mounting bracket 11 and a laser module 12 arranged along a second direction Y, and a limiting structure 15 is disposed on the surface of the mounting bracket 11 facing away from the laser module 12.

[0085] See also Figure 2 and Figure 3 In one embodiment, the limiting structure 15 includes a first limiting member 151 and a second limiting member 152. There are two first limiting members 151, which are arranged opposite each other along the third direction Z. The first direction X and the second direction Y both intersect with the third direction Z. The second limiting member 152 is located on one side of the back plate 21 along the first direction X. The second limiting member 152 and the two first limiting members 151 enclose a limiting space 153. The second limiting member 152 is arranged opposite to the first clearance opening, and the back plate 21 abuts against the second limiting member 152.

[0086] In this embodiment, the limiting structure 15 includes two first limiting members 151 arranged along the third direction Z, and a second limiting member 152 disposed opposite to the first clearance opening. In this arrangement, after the back plate 21 is inserted into the limiting space 153, the back plate 21 abuts against the second limiting member 152, so that the back plate 21 and the second limiting member 152 are limited in the first direction X, thereby improving installation stability.

[0087] Optionally, the second limiting member 152 can be connected to the first limiting member 151, or it can be set separately from the first limiting member 151.

[0088] See also Figure 2 and Figure 3 In one embodiment, the second limiting member 152 is connected to the back plate 21.

[0089] In this embodiment, by connecting the second limiting member 152 to the back plate 21 to connect the laser head 10 to the mounting base 20, the connection direction of the laser head 10 and the mounting base 20 is the same as the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23. This allows the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the first liquid outlet connector 19 and the second liquid outlet connector 27, to be stably inserted and engaged. Furthermore, it avoids the problem of corresponding two connectors being squeezed against each other in the non-insertion direction when fixing the laser module 12 due to the intersection of the direction of the connection force with the insertion direction of each connector. This prevents connector damage and ensures a sealed connection between the corresponding two connectors, avoiding leakage.

[0090] Specifically, a first connecting portion 154 can be provided on the second limiting member 152 as described in the previous embodiment, and a corresponding second connecting portion 213 can be provided on the side of the back plate 21 facing the second limiting member 152, so that the second limiting member 152 and the back plate 21 are connected through the first connecting portion 154 and the second connecting portion 213. The setting method and connection method of the first connecting portion 154 and the second connecting portion 213 are the same as those described in the previous embodiment, and will not be repeated here.

[0091] See also Figure 2 and Figure 3 In one embodiment, the limiting structure 15 includes two second limiting members 152 spaced apart along the third direction Z, and a second clearance opening is formed between the two second limiting members 152 opposite to the first clearance opening. The back plate 21 includes a plate body 211 and a protrusion structure 212. The plate body 211 is located in the limiting space 153 and connected to the seat 22. The protrusion structure 212 passes through the second clearance opening.

[0092] In this embodiment, the back plate 21 includes a plate body 211 and a protruding structure 212 connected to the plate body 211. The protruding structure 212 is located on one side of the plate body 211 along the first direction X. When the laser head 10 is installed on the mounting base 20, the back plate 21 is inserted into the limiting structure 15 along the first direction X, so that the plate body 211 is limited in the limiting space 153. The protruding structure 212 passes through the second clearance opening between the two second limiting members 152, and the plate body 211 abuts against the second limiting members 152. This arrangement can improve the stability of mutual limiting between the laser head 10 and the mounting base 20 and improve the connection strength. In some embodiments, the protruding structure 212 can also increase the area of ​​the back plate 21 to increase the fixing area of ​​the mounting base 20.

[0093] See also Figure 1 and Figure 4 In one embodiment, the laser head 10 includes a first region that abuts against the base 22 and a second region that is misaligned with the base 22, with the light-emitting area of ​​the laser head 10 located in the second region.

[0094] When the laser head module 100 is applied to a laser processing equipment, the laser head 10 is typically located above the processing platform that supports the processing material, emitting laser light downwards to process the material. In this embodiment, the laser head 10 emits light along a first direction X, meaning the base 22 is positioned below the laser head 10 to support it. This improves the installation stability of the laser head 10 and reduces the risk of it falling. Furthermore, the light-emitting area of ​​the laser head 10 is located in a second area offset from the base 22, preventing the base 22 from obstructing the light-emitting area and thus avoiding blocking the laser emission.

[0095] Optionally, the first liquid inlet connector 13 and the first liquid outlet connector 19 of the laser head 10 can be set in the first region, and the second liquid inlet connector 23 and the second liquid outlet connector can be set on the side of the base 22 facing the first region. In this arrangement, the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the insertion direction of the first liquid outlet connector 19 and the second liquid outlet connector 17, are the same as the direction of gravity, making the connection between the two stable and not easy to separate.

[0096] Please see Figure 1 and Figure 5 In one embodiment, the laser head 10 is provided with a first stepped surface 1425, a first liquid inlet connector 13 and a first liquid outlet connector 19 are provided on the first stepped surface 1425, and the mounting base 20 is provided with a second stepped surface 223 adapted to the first stepped surface 1425. The second liquid inlet connector 23 and the second liquid outlet connector 27 are provided on the second stepped surface 223, and the first stepped surface 1425 and the second stepped surface 223 are in contact.

[0097] In this embodiment, the laser head 10 is provided with a first stepped surface 1425, which includes two or more stepped surfaces. The mounting base 20 is provided with a second stepped surface 223, which also includes two or more stepped surfaces. When the laser head 10 is installed on the mounting base 20, the first stepped surface 1425 and the second stepped surface 223 are interlocked. The stepped surfaces fit together to limit the laser head 10 and the mounting base 20, so that the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the first liquid outlet connector 19 and the second liquid outlet connector 27, are accurately inserted. This avoids misalignment of the laser head 10 and the mounting base 20 in the extending direction of the first stepped surface 1425 and the second stepped surface 223, thus preventing the two inserted connectors from squeezing and interfering with each other in that direction.

[0098] Optionally, one of the stepped surfaces of the first stepped surface 1425 is provided with a second passage 1424 for laser emission. This stepped surface is offset from the second stepped surface 223 to prevent the mounting base 20 from blocking the laser emission.

[0099] Optionally, the laser head 10 includes a housing 14 and a mounting bracket 11, which together form a mounting cavity 1411 for mounting the laser module 12. A first stepped surface 1425 is disposed on the housing 14, for example, on the bottom cover 142 of the housing 14.

[0100] In one embodiment, the laser head 10 further includes a first shut-off valve (not shown) disposed on the first liquid inlet connector 13. When the first liquid inlet connector 13 and the second liquid inlet connector 23 are separated, the first shut-off valve blocks the first liquid inlet connector 13. When the first liquid inlet connector 13 and the second liquid inlet connector 23 are connected, the first shut-off valve opens the first liquid inlet connector 13.

[0101] In this embodiment, by providing a first shut-off valve in the first liquid inlet connector 13, when the laser head 10 separates from the mounting base 20 and the first liquid inlet connector 13 separates from the second liquid inlet connector 23, the first liquid inlet connector 13 can be closed by the first shut-off valve, thereby preventing the residual coolant in the liquid cooling channel from leaking out from the first liquid inlet connector 13.

[0102] Optionally, the first shut-off valve may include a first valve seat, a first valve core, and a first elastic element. The first valve core is movably disposed in the first inlet connector 13 and has a blocking position for blocking the first inlet connector 13 and an opening position for opening the first inlet connector 13. The first elastic element acts between the first valve seat and the first valve core and can apply an elastic force to the first valve core, causing the first valve core to tend to move to the blocking position. When the second inlet connector 23 is inserted into the first inlet connector 13, the push structure provided in the second inlet connector 23 can overcome the elastic force of the first elastic element and push the first valve core to the opening position, so that the first inlet connector 13 is conductive, thereby connecting the first inlet connector 13 and the second inlet connector 23.

[0103] In one embodiment, the mounting base 20 further includes a second shut-off valve (not shown) disposed on the second liquid inlet connector 23. When the first liquid inlet connector 13 and the second liquid inlet connector 23 are separated, the second shut-off valve blocks the second liquid inlet connector 23. When the first liquid inlet connector 13 and the second liquid inlet connector 23 are connected, the second shut-off valve opens the second liquid inlet connector 23.

[0104] In this embodiment, by providing a second shut-off valve in the second liquid inlet connector 23, when the laser head 10 separates from the mounting base 20 and the first liquid inlet connector 13 separates from the second liquid inlet connector 23, the second liquid inlet connector 23 can be closed by the second shut-off valve, thereby preventing the residual coolant in the liquid cooling channel from leaking out from the second liquid inlet connector 23.

[0105] Optionally, the second shut-off valve may include a second valve seat, a second valve core, and a second elastic element. The second valve core is movably disposed in the second inlet connector 23 and has a blocking position for sealing the second inlet connector 23 and an opening position for opening the second inlet connector 23. The second elastic element acts between the second valve seat and the second valve core and can apply an elastic force to the second valve core, causing the second valve core to tend to move to the blocking position. When the first inlet connector 13 and the second inlet connector 23 are inserted and engaged, the push structure provided in the first inlet connector 13 can overcome the elastic force of the second elastic element and push the second valve core to the opening position, so that the second inlet connector 23 is conductive, thereby connecting the first inlet connector 13 and the second inlet connector 23.

[0106] In some embodiments, a first shut-off valve is provided in the first inlet connector 13, and a second shut-off valve is provided in the second inlet connector 23. When the first inlet connector 13 and the second inlet connector 23 are inserted and engaged, the first valve core of the first shut-off valve and the second valve core of the second shut-off valve abut against each other and interact, thereby moving both the first valve core and the second valve core to their respective open positions, thus communicating between the first inlet connector 13 and the second inlet connector 23. Optionally, one of the first valve core of the first shut-off valve and the second valve core of the second shut-off valve is configured as a piston, and the other is configured as a push rod.

[0107] In one embodiment, the laser head 10 further includes a third shut-off valve (not shown) disposed on the first liquid outlet connector 19. When the first liquid outlet connector 19 and the second liquid outlet connector 27 are separated, the third shut-off valve blocks the first liquid outlet connector 19. When the first liquid outlet connector 19 and the second liquid outlet connector 27 are connected, the third shut-off valve opens the first liquid outlet connector 19.

[0108] In this embodiment, by providing a third shut-off valve in the first liquid outlet connector 19, when the laser head 10 separates from the mounting base 20 and the first liquid outlet connector 19 separates from the second liquid outlet connector 27, the first liquid outlet connector 19 can be closed by the third shut-off valve, thereby preventing the residual coolant in the liquid cooling channel from leaking out from the first liquid outlet connector 19.

[0109] Optionally, the third shut-off valve may include a third valve seat, a third valve core, and a third elastic element. The third valve core is movably disposed in the first outlet connector 19 and has a blocking position for blocking the first outlet connector 19 and an opening position for opening the first outlet connector 19. The third elastic element acts between the third valve seat and the third valve core and can apply an elastic force to the third valve core, causing the third valve core to tend to move to the blocking position. When the second outlet connector 27 is inserted into the first outlet connector 19, the push structure provided in the second outlet connector 27 can overcome the elastic force of the third elastic element and push the third valve core to the opening position, so that the first outlet connector 19 is connected, thereby connecting the first outlet connector 19 and the second outlet connector 27.

[0110] In one embodiment, the mounting base 20 further includes a fourth shut-off valve (not shown) disposed on the second liquid outlet connector 27. When the first liquid outlet connector 19 and the second liquid outlet connector 27 are separated, the fourth shut-off valve blocks the second liquid outlet connector 27. When the first liquid outlet connector 19 and the second liquid outlet connector 27 are connected, the fourth shut-off valve opens the second liquid outlet connector 27.

[0111] In this embodiment, by providing a fourth shut-off valve in the second liquid outlet connector 27, when the laser head 10 separates from the mounting base 20 and the first liquid outlet connector 19 separates from the second liquid outlet connector 27, the second liquid outlet connector 27 can be closed by the fourth shut-off valve, thereby preventing the residual coolant in the liquid cooling channel from leaking out from the second liquid outlet connector 27.

[0112] Optionally, the fourth shut-off valve may include a fourth valve seat, a fourth valve core, and a fourth elastic element. The fourth valve core is movably disposed in the second outlet connector 27 and has a blocking position for blocking the second outlet connector 27 and an opening position for opening the second outlet connector 27. The fourth elastic element acts between the fourth valve seat and the fourth valve core and can apply an elastic force to the fourth valve core, causing the fourth valve core to tend to move to the blocking position. When the first outlet connector 19 and the second outlet connector 27 are inserted and engaged, the push structure provided in the first outlet connector 19 can overcome the elastic force of the fourth elastic element and push the fourth valve core to the opening position, so that the second outlet connector 27 is conductive, thereby connecting the first outlet connector 19 and the second outlet connector 27.

[0113] In some embodiments, a third shut-off valve is provided in the first outlet connector 19, and a fourth shut-off valve is provided in the second outlet connector 27. When the first outlet connector 19 and the second outlet connector 27 are inserted and engaged, the third valve core of the third shut-off valve and the fourth valve core of the fourth shut-off valve abut against each other and interact, thereby moving both the third and fourth valve cores to their respective open positions, thus communicating between the first outlet connector 19 and the second outlet connector 27. Optionally, one of the third valve core of the third shut-off valve and the fourth valve core of the fourth shut-off valve may be configured as a piston, and the other as a push rod.

[0114] See also Figure 5 , Figure 6 as well as Figure 8 In one embodiment, the laser head 10 is provided with an air blowing module and an air inlet connector 16 connected to the air blowing module. The mounting base 20 is provided with an air guiding channel 222. The air inlet connector 16 and the air outlet of the air guiding channel 222 are connected and communicate with each other along the first direction X.

[0115] In this embodiment, the laser head 10 is equipped with an air blowing module. This module can be used to blow air into the processing area during laser processing, or to blow air into the optical path structure of the laser head 10, such as optical lenses, for dust removal. It can also be used for air cooling. The air blowing module is connected to the outlet end of the air inlet connector 16, allowing airflow to reach the air blowing module through the inlet connector 16. The mounting base 20 is provided with an air guide channel 222. The inlet end of the air guide channel 222 is used to connect to an air supply module such as an air pump module, and the outlet end of the air guide channel 222 is used to connect to the air inlet connector 16 for mutual communication. When the laser head module 100 is applied to a laser processing equipment, the airflow driven by the air supply module can flow to the air blowing module via the air guide channel 222 and the air inlet connector 16. Optionally, an air pipe connector 26 can be connected to the inlet end of the air guide channel 222 to connect to an air inlet pipe connected to the air supply module.

[0116] In this embodiment, when the laser head module 100 is applied in a laser processing equipment, the mounting base 20 is fixed on the module mounting position in the laser processing equipment and keeps in communication with the liquid cooling system and the gas supply module. The mating direction of the air inlet connector 16 and the air guide channel 222 is consistent with the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the insertion direction of the first liquid outlet connector 19 and the second liquid outlet connector 27. Thus, when the laser head 10 is installed on the mounting base 20, the air path and water path of the laser head 10 and the mounting base 20 can be connected simultaneously without the need for additional air path connection operations, making the installation and removal of the laser head 10 more convenient.

[0117] See also Figure 6 and Figure 8 In one embodiment, the laser head module 100 further includes a sealing element 40, which is disposed at the outlet end of the air guide channel 222 and is annular, and is sandwiched between the laser head 10 and the mounting base 20 to seal the gap between the air inlet connector 16 and the outlet end of the air guide channel 222.

[0118] In this embodiment, the laser head module 100 is provided with a sealing element 40. The sealing element 40 can be, but is not limited to, a sealing ring, a nut gasket, etc. The sealing element 40 has a certain elasticity and can be clamped by the laser head 10 and the mounting base 20 when the laser head 10 is installed on the mounting base 20. The sealing element 40 can seal the gap between the air outlet end of the air guide channel 222 and the air inlet connector 16, thereby playing a good sealing role and avoiding air leakage.

[0119] See also Figure 3 , Figure 5 as well as Figure 9In one embodiment, the laser head 10 further includes a first electrical connection structure 17, and the mounting base 20 includes a second electrical connection structure 24, which is used for electrical connection with the control system of the laser processing equipment; the first electrical connection structure 17 and the second electrical connection structure 24 are plugged into each other along a first direction X to make the laser head 10 and the control system electrically connected.

[0120] In this embodiment, the laser head 10 is provided with a first electrical connection structure 17 for receiving power. The first electrical connection structure 17 is electrically connected to the electrical components in the laser head 10, such as the laser module 12, or the position detection structure in the following embodiment. The first electrical connection structure 17 is used to enable the laser head to receive electrical energy and control signals, so as to provide electrical energy and transmit signals to the electrical components in the laser head 10. The first electrical connection structure 17 may include a first connector plug, or it may include a first adapter plate electrically connected to the first connector plug, and be electrically connected to the electrical components in the laser head 10 through the first adapter plate. Optionally, the first adapter plate may be disposed on the mounting bracket 11 of the laser module 10, or disposed inside the laser module 10, which is not limited here.

[0121] The mounting base 20 is provided with a second connection structure 24 for connecting to the control system of the laser processing equipment. The second electrical connection structure 24 may include a second connection plug for plugging into the first electrical connection structure 17. In some embodiments, the second electrical connection structure 24 may also include a second adapter plate, on which the second connection plug is disposed and electrically connected. The second adapter plate is used for electrical connection with the control system of the laser processing equipment. Optionally, the second adapter plate may be disposed on the back plate 21 of the mounting base 20 or on the base body 22 of the mounting base 20, which is not limited here.

[0122] In this embodiment, the first electrical connection structure 17 and the second electrical connection structure 24 are plugged into each other for electrical connection. Blade sockets or other types of connectors that can be plugged into each other can be provided on the first electrical connection structure 17 and the second electrical connection structure 24. The plugging direction of the first electrical connection structure 17 and the second electrical connection structure 24 is the same as the plugging direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, and the plugging direction of the first liquid outlet connector 19 and the second liquid outlet connector 27. Therefore, when the laser head 10 is installed on the mounting base 20, the electrical circuit and water circuit of the laser head 10 and the mounting base 20 can be connected simultaneously without additional circuit connection operations, improving the ease of installation and removal of the laser head 10.

[0123] See also Figure 5 , Figure 6 as well as Figure 8In one embodiment, the laser head module 100 further includes a position detection element 50, which is disposed on one of the laser head 10 and the mounting base 20. The position detection element 50 is triggered when the laser head 10 is mounted on the mounting base 20.

[0124] In this embodiment, a position detection element 50 is provided in the laser head module 100. The position detection element 50 may include at least one detection element 52 such as a proximity switch, a Hall element, or a photoelectric sensor. When the laser head module 100 is used in a laser processing equipment, the laser head 10 can be electrically connected to the control system of the laser processing equipment, for example, the laser head 10 can be directly connected to the control system of the laser processing equipment. In this case, the position detection element 50 can be mounted on the laser head 10. In addition, in some embodiments, the laser head 10 is electrically connected to the mounting base 20, and the mounting base 20 is electrically connected to the control system of the laser processing equipment. In this case, the position detection element 50 can be mounted on the laser head 10 or on the mounting base 20.

[0125] When the laser head 10 is installed on the mounting base 20, the position detection element 50 is triggered to send a detection signal to determine that the laser head 10 is installed in place. When the laser head 10 is removed from the mounting base 20, the detection signal is interrupted, thus indicating that the laser head 10 has been removed or is misaligned. This configuration allows the laser processing equipment to accurately determine the installation status of the laser head 10, preventing the laser processing equipment from operating when the laser head 10 is not properly installed.

[0126] Optionally, the position detection device 50 includes a circuit board 51 and a detection device 52. The detection device 52 is integrated on the circuit board 51 and electrically connected to the circuit board 51. The detection device 52 can be, but is not limited to, at least one of a proximity switch, a Hall element, or a photoelectric sensor. The circuit board 51 can provide power to the detection device 52 and can also be used to process, receive, and transmit the detection signals from the detection device 52.

[0127] This application also proposes a laser processing device, which includes a motion component, a laser head module 100, and a liquid cooling system. The specific structure of the laser head module 100 is as described in the above embodiment. The mounting base 20 of the laser head module 100 is mounted on the motion component, and the liquid cooling system is connected to the guide channel 221 of the mounting base 20.

[0128] The laser processing equipment proposed in this application can be used for at least one laser processing operation, such as laser marking, laser welding, laser cutting, and laser engraving. The laser processing equipment includes a processing platform for placing processing materials. The laser head module 100 is located above the processing platform and can be driven by a motion component to move to different areas of the processing platform for laser processing. Optionally, the motion component may include intersecting first and second slide rails. The first slide rail is slidably mounted on the first slide rail, and the mounting base 20 of the laser head module 100 is slidably mounted on the second slide rail. The motion component also includes a first drive mechanism for driving the second slide rail to slide along the first slide rail, and a second drive mechanism for driving the mounting base 20 to move along the second slide rail. The first drive mechanism can be configured as one of a motor screw mechanism, a synchronous belt mechanism, and a cylinder pushing mechanism, and the second drive mechanism can be configured as one of a motor screw mechanism, a synchronous belt mechanism, and a cylinder pushing mechanism; no limitation is made here. Optionally, the laser processing equipment may also include a lifting assembly, which can be mounted on a motion assembly, such as on a second slide rail, so that the mounting base 20 is positioned on the lifting assembly, so that the mounting base 20 can be driven to rise and fall by the lifting assembly, and can be translated as the lifting assembly is driven by the motion assembly.

[0129] In the embodiment of the application, the laser processing equipment is also provided with a liquid cooling system. The liquid inlet channel and liquid outlet channel provided on the mounting base 20 are connected to the liquid cooling system. The liquid cooling system can introduce the coolant with a lower temperature from the liquid inlet channel into the liquid cooling channel. The coolant flows along the liquid cooling channel and exchanges heat with the laser head 10 before flowing out of the liquid cooling channel and flowing back into the liquid cooling system through the liquid outlet channel. This can remove the heat from the laser head 10, thereby achieving heat dissipation and cooling of the laser head 10. The cooling system can also cool the coolant.

[0130] Optionally, the laser head 10 is equipped with an air blowing module and an air inlet connector 16 connected to the air outlet module. The air blowing module can be used to blow air into the processing area during laser processing, or to blow air into the optical path structure such as the optical lenses of the laser head 10 for dust removal. The air blowing module can also be used to blow air for heat dissipation. The mounting base 20 is provided with an air guide channel 222, and the air inlet end of the air guide channel 222 is connected to an air supply module such as an air pump module. When the laser head 10 is installed on the mounting base 20, the air inlet connector 16 is directly connected to the air outlet end of the air guide channel 222. The connection direction of the air inlet connector 16 and the air guide channel 222 is consistent with the insertion direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, as well as the insertion direction of the first liquid outlet connector 19 and the second liquid outlet connector 27. This allows the laser head 10 to be connected to the air and water paths of the mounting base 20 simultaneously, without the need for additional air path connection operations, making the installation and removal of the laser head 10 more convenient.

[0131] Optionally, the laser head 10 is provided with a first electrical connection structure 17 for power connection, and the mounting base 20 is provided with a second electrical connection structure 24 for connecting to the control system of the laser processing equipment. The second electrical connection structure 24 is electrically connected to the control system of the laser processing equipment. When the laser head 10 is installed on the mounting base 20, the first electrical connection structure 17 and the second electrical connection structure 24 are plugged into each other for electrical connection. Blade sockets or other forms of connectors that can be plugged into each other can be provided on the first electrical connection structure 17 and the second electrical connection structure 24. Furthermore, by making the plugging direction of the first electrical connection structure 17 and the second electrical connection structure 24 the same as the plugging direction of the first liquid inlet connector 13 and the second liquid inlet connector 23, and the plugging direction of the first liquid outlet connector 19 and the second liquid outlet connector 27, the electrical and water circuits of the laser head 10 and the mounting base 20 can be simultaneously connected without additional electrical connection operations, improving the ease of installation and removal of the laser head 10.
