Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a processing module and a laser processing equipment. Background Technology

[0002] Currently, laser processing equipment such as laser engraving machines and laser cutting machines incorporate air-blowing modules in the laser head to blow air into the processing area. This removes impurities such as molten material generated during processing and cools the area, reducing the risk of scorched edges and material ignition. However, in these technologies, the air nozzles of the air-blowing module need to be manually changed to meet different blowing ranges, flow rates, and pressure requirements for different materials and processing needs, which is inconvenient.

[0039] This utility model proposes a processing module 100 for use in laser processing equipment.

[0040] Please see Figures 1 to 6 In one embodiment of the present invention, the processing module 100 includes at least two types of air nozzles 3, an air nozzle holder 1, and a processing head assembly 2. At least two types of air nozzles 3 can be placed on the air nozzle holder 1. The processing head assembly 2 is provided with an air blowing channel 2224 and a laser transmission channel. Any air nozzle 3 can be detachably connected to the processing head assembly 2 and communicate with the outlet of the air blowing channel 2224. The processing head assembly 2 can be moved to the air nozzle holder 1 to replace the air nozzle 3.

[0041] In one embodiment, the laser processing equipment includes a frame, a moving component, a laser generator, and a processing module 100. The frame has a processing space, and the moving component is disposed within the processing space, which can be used to drive the laser generator to different positions for laser processing. Optionally, the moving component includes a vertically arranged first slide rail and a second slide rail. The second slide rail is slidably disposed on the first slide rail, and the laser generator is slidably disposed on the second slide rail, so that the laser generator can slide along the second slide rail and, along the second slide rail, slide along the first slide rail. The laser generator can be used to generate laser light for laser processing operations such as laser welding, laser cutting, laser marking, and laser engraving.

[0042] In one embodiment, the processing module 100 includes at least two types of nozzles 3 with different structural designs. The structural differences in the nozzles 3 can be at least one of the following: nozzle length, nozzle outlet size, and outlet shape. By switching between different nozzles 3, at least one of the following states can be controlled: the shape of the blown airflow, the gas diffusion area, and the gas flow rate. The nozzle holder 1 can be used to place nozzles 3 that are not currently in use. The nozzle holder 1 has at least two mounting positions, each capable of holding one type of nozzle 3. Each mounting position can be equipped with at least one locking structure, such as a clamping structure, a snap-fit ​​structure, or a magnetic structure, to improve the positional stability of the nozzle 3 at the mounting position. When applied to laser processing equipment, the nozzle holder 1 is fixed to the frame.

[0043] The processing head assembly 2 is used in conjunction with a laser generator. It can be directly connected to the laser generator, or a mounting bracket for mounting the processing head assembly 2 and the laser generator can be provided on the moving component of the laser processing equipment. Both the processing head assembly 2 and the laser generator are fixed on the mounting bracket to maintain their relative positions. The processing head assembly 2 includes a laser transmission channel and an air blowing channel 2224 for air output. Optionally, the laser transmission channel and the air blowing channel 2224 can be coaxially arranged, sharing the same path, with the laser and airflow output along the same channel. Alternatively, the laser transmission channel and the air blowing channel 2224 can be independent, with the laser and airflow output from different channels.

[0044] Any type of nozzle 3 in the processing module 100 can be detachably connected to the processing head assembly 2. The nozzle 3 and the processing head assembly 2 can be detachably connected by at least one of the following methods: magnetic connection, plug-in connection, etc. In practical applications, the processing head assembly 2 is connected to one type of nozzle 3. The nozzle 3 that is not currently in use is placed on the nozzle holder 1, and the nozzle holder 1 has at least one unused mounting position. When it is necessary to replace the nozzle 3, the moving component of the laser processing equipment drives the processing head assembly 2 and the laser generator to the position of the nozzle holder 1. The nozzle 3 connected to the processing head assembly 2 is placed in the unused mounting position of the nozzle holder 1, and the nozzle 3 is locked by the locking structure. The processing head assembly 2 is then removed, leaving the nozzle 3 originally connected to the processing head assembly 2 on the nozzle holder 1. The processing head assembly 2 is then moved to the position of the nozzle 3 to be replaced, and the processing head assembly 2 is connected to the nozzle 3, thereby completing the replacement of the nozzle 3.

[0045] In other words, the technical solution of this utility model embodiment, by setting a processing module 100 including an air nozzle 3, an air nozzle holder 1, and a processing head assembly 2, allows the processing head assembly 2 to be used in conjunction with a laser generator. At least two types of air nozzles 3 can be mounted on the air nozzle holder 1, and any one of these air nozzles 3 can be detachably connected to the processing head assembly 2. When the processing module 100 is applied to a laser processing equipment, the processing head assembly 2 can move within the laser processing equipment to different positions along with the laser generator for processing. Furthermore, the processing head assembly 2 can move to the position of the air nozzle holder 1 to automatically replace the air nozzle 3, eliminating the need for manual replacement and improving the convenience of replacing the air nozzle 3 in the laser processing equipment.

[0046] In one embodiment, the air nozzle 3 is magnetically connected to the processing head assembly 2.

[0047] Specifically, magnets can be installed on both the air nozzle 3 and the processing head assembly 2; alternatively, a magnet can be installed on the air nozzle 3, and a metal structure that can be attracted by the magnet can be installed on the processing head assembly 2; or the air nozzle 3 can be made of metal or have a metal magnetic structure installed on it, and a magnet can be installed on the processing head assembly 2. All these configurations allow the air nozzle 3 and the processing head assembly 2 to be magnetically connected, improving the ease of assembly and disassembly of both components.

[0048] Please see Figure 6 and Figure 7 In one embodiment, the air nozzle holder 1 includes at least two snap-fit ​​structures 11, each including two snap-fit ​​arms 111 arranged side by side. The outer wall of the air nozzle 3 is provided with two slots 31 arranged back to back. The air nozzle 3 can be disposed between the two snap-fit ​​arms 111 of any snap-fit ​​structure 11, and the two snap-fit ​​arms 111 are respectively snapped into the two slots 31.

[0049] In this embodiment, the nozzle holder 1 is provided with a snap-fit ​​structure 11 for mounting the nozzle 3. Each snap-fit ​​structure 11 forms a snap-fit ​​space through two snap-fit ​​arms 111. Optionally, two adjacent snap-fit ​​structures 11 can share one snap-fit ​​arm 111, or the snap-fit ​​arms 111 of each snap-fit ​​structure 11 can be independent. Optionally, the snap-fit ​​structure 11 also includes a back plate 112, and the snap-fit ​​arms 111 are connected to the back plate 112 to form a snap-fit ​​space with the back plate 112. The back plates 112 of each snap-fit ​​structure 11 can be connected to each other or can be set separately. Correspondingly, slots 31 are provided on the two opposite sides of the nozzle 3. When the nozzle 3 is snapped into the snap-fit ​​space, the two snap-fit ​​arms 111 are respectively inserted into the two slots 31, thereby connecting the nozzle 3 to the nozzle holder 1. In this configuration, the air nozzle 3 can move in and out of the snap-fit ​​space along the extension direction of the snap-fit ​​arm 111. When the air nozzle 3 needs to be replaced, the processing head assembly 2 moves so that the air nozzle 3 connected to the processing head assembly 2 enters the snap-fit ​​space of one of the snap-fit ​​structures 11. Since the air nozzle 3 is limited by the snap-fit ​​structure 11, the processing head assembly 2 and the air nozzle 3 separate from each other when the processing head assembly 2 moves upward. Then, the processing head assembly 2 moves to the position of the air nozzle 3 to be replaced, connects with the air nozzle 3, and drives the air nozzle 3 to move along the length direction of the snap-fit ​​arm 111 so that the air nozzle 3 is disengaged from the air nozzle holder 1.

[0050] It should be noted that in this embodiment, the processing head assembly 2 and the air nozzle 3 can be detachably connected by a plug-in connection or by a magnetic connection as in the above embodiment, so that the processing head assembly 2 can be connected or separated from the air nozzle 3 when it is raised or lowered.

[0051] Please see Figure 7 In one embodiment, the laser transmission channel and the air blowing channel 2224 are coaxial and interconnected.

[0052] In this configuration, both the laser and the airflow are blown outward from the nozzle 3. This reduces the number of channels in the processing head assembly 2 and effectively prevents dust and other impurities from entering the laser transmission channel during processing, thus achieving a better dust removal effect and ensuring the laser processing effect.

[0053] In one embodiment, the processing head assembly 2 includes a mounting bracket 21, a base structure 22, an optical path structure 23, a focusing lens 24, and a drive structure 25. The base structure 22 is vertically mounted on the mounting bracket 21 and has an air blowing channel 2224. The air nozzle 3 is detachably connected to the base structure 22. The optical path structure 23 includes a fixed sleeve 231 and a movable sleeve 232 that fit together and can slide relative to each other. The fixed sleeve 231 is connected to the mounting bracket 21 and has a laser transmission channel that passes through the fixed sleeve 231 and the movable sleeve 232. One end of the movable sleeve 232 is connected to the base structure 22. The focusing lens 24 is located in the base structure 22. The drive structure 25 is connected to the base structure 22 and is used to drive the base structure 22 to rise and fall.

[0054] In this embodiment, the processing head assembly 2 includes a mounting bracket 21 for connecting to a movable component of a laser processing equipment or a laser generator. The mounting bracket serves as the mounting base for the gas devices in the processing head assembly 2. The base structure 22, the optical path structure 23, and the drive structure 25 are all mounted on the mounting bracket 21. The optical path structure 23 forms a laser transmission channel. The base structure 22 is located at the light-emitting end of the optical path structure 23 and is connected to the movable sleeve 232 of the optical path structure 23. The base structure 22 can be driven by the drive structure 25 to rise and fall, adjusting the height of the gas nozzle 3 and allowing the processing head assembly 2 to connect or disconnect from the gas nozzle 3 at the gas nozzle holder 1 position when the gas nozzle 3 needs to be replaced. The drive structure 25 can be a cylinder or other pushing structure, or a drive motor can be used as the driving component. For example, a screw drive structure can be used to connect the drive motor and the base structure 22; no limitation is made here.

[0055] In this embodiment, a focusing lens 24 is also disposed in the base structure 22. The focusing lens 24 is used to focus the laser and improve the laser energy density. The focusing lens 24 is disposed in the base structure 22 so that the focusing lens 24, the base structure 22 and the air nozzle 3 can be raised and lowered synchronously, which can adjust the focal point position of the laser focusing, and the relative position of the focusing lens 24 and the air nozzle 3 in the lifting direction remains fixed. Furthermore, there is no need to separately set up a drive structure 25 to drive the base structure 22 and the focusing lens 24 to rise and fall, which simplifies the structure of the processing head assembly 2, reduces the weight of the processing head assembly 2, thereby reducing the motion load and making the movement of the processing head assembly 2 more stable.

[0056] Optionally, in this embodiment, an air inlet communicating with the air blowing channel 2224 can be provided on the side wall of the seat structure 22. Alternatively, in the following embodiment, an air inlet communicating with the laser transmission channel can be provided on the optical path structure 23, and a ventilation groove 2225 can be provided on the seat structure 22 to communicate with the laser transmission channel and the air blowing channel 2224. In both cases, airflow can enter the air blowing channel 2224 and flow towards the nozzle 3 to blow outwards.

[0057] Please see Figure 6 In one embodiment, the optical path structure 23 is provided with an air inlet that connects to the laser transmission channel, and the inner wall of the base structure 22 is provided with a ventilation groove 2225. The ventilation groove 2225 is located on the periphery of the focusing lens 24 and connects the laser transmission channel and the air blowing channel 2224.

[0058] In this embodiment, the airflow enters the laser transmission channel of the optical path structure 23 through the air inlet, flows into the blowing channel 2224 through the venting groove 2225 on the side of the focusing lens 24, and is then blown out from the air nozzle 3. This arrangement also cleans the focusing lens 24 as the airflow passes through it, preventing dust from accumulating on the focusing lens 24 and affecting laser emission, thus ensuring laser emission and processing results.

[0059] Optionally, the air inlet can be located on the side wall of the fixed sleeve 231 of the optical path structure 23, or on the side wall of the movable sleeve 232; alternatively, it can also be located on the reflector module 233 of the optical path structure 23 in the following embodiments, without limitation.

[0060] Please see Figure 6 In one embodiment, the optical path structure 23 further includes a reflector module 233 disposed at the light-inlet end of the fixed sleeve 231. The reflector module 233 includes a housing 2331 and a reflector 2332 disposed in the housing 2331. The housing 2331 is connected to the fixed sleeve 231. The side wall of the housing 2331 is provided with a light inlet 2333 and an air inlet. The light inlet 2333 is disposed facing the reflector 2332.

[0061] In this embodiment, the optical path structure 23 of the processing head assembly 2 further includes a reflector module 233. The reflector module 233 is provided with a housing 2331 and a reflector 2332 installed in the housing 2331. The side wall of the housing 2331 is provided with a light inlet 2333 and an air inlet. The laser enters the housing 2331 along the light inlet 2333 and is projected onto the reflector 2332. The laser optical path is changed by the reflector 2332 so that the laser is injected into the laser transmission channel. With this arrangement, when the processing head assembly 2 is used in a laser processing equipment, the laser generator can be located on the side of the processing head assembly 2, without having to arrange the laser generator and the processing head assembly 2 along the height direction, reducing the space occupied in the height direction, which is beneficial to reducing the height of the laser processing equipment.

[0062] The air inlet is located on the side wall of the housing 2331 of the reflector module 233. Airflow enters the housing 2331 through the air inlet and flows into the laser transmission channel. During this process, some airflow passes through the reflector 2332, which also cleans the reflector 2332, preventing interference with laser transmission and ensuring laser transmission and processing effects. Optionally, the air inlet and the light inlet 2333 can be located on the same side wall of the housing 2331 or on different side walls; this is not limited. Optionally, the optical path assembly also includes an air inlet connector 2334 located at the air inlet for easy connection to an air pipe.

[0063] Please see Figure 1 In one embodiment, the optical path structure 23 further includes a sealing element 234, which is disposed between the fixed sleeve 231 and the movable sleeve 232.

[0064] The sealing element 234 can be set as a sealing ring, such as a V-type sealing ring, a Y-type sealing ring, a YX-type sealing ring, a self-lubricating sealing gasket, or other sealing structures. The sealing element 234 can seal the gap between the fixed sleeve 231 and the movable sleeve 232, and avoid problems such as laser leakage and airflow leakage between the fixed sleeve 231 and the movable sleeve 232.

[0065] Please see Figure 6 In one embodiment, the seat structure 22 includes an air nozzle connector 222 and a connecting seat 221. The connecting seat 221 is slidably connected to the mounting bracket 21 and connected to the drive structure 25. The air nozzle connector 222 is detachably connected to the connecting seat 221 and is provided with an air blowing channel 2224. The focusing lens 24 is provided on the air nozzle 3 structure, and the air nozzle 3 is detachably connected to the air nozzle connector 222.

[0066] In this embodiment, the connecting seat 221 of the base structure 22 is slidably connected to the mounting bracket 21, and the connecting seat 221 is drive-connected to the drive structure 25. The air nozzle connector 222 with the air blowing channel 2224 is detachably connected to the connecting seat 221. With this arrangement, when the air blowing channel 2224 needs to be cleaned and maintained, or when the focusing lens 24 needs to be replaced or cleaned, it is not necessary to disassemble the entire base structure 22. The connecting seat 221, which is slidably connected to the mounting bracket 21 and drive-connected to the drive structure 25, can be retained. Only the air nozzle connector 222 needs to be disassembled for cleaning or replacement, which improves the convenience of use.

[0067] Please see Figure 5In one embodiment, the connecting seat 221 includes a seat body 2211 located above and opposite to the air nozzle connector 222. The seat body 2211 has a plug groove 2213 with a side opening and a bottom opening. The top wall of the seat body 2211 has a through hole communicating with the plug groove 2213. One end of the movable sleeve 232 is inserted into the through hole. The air nozzle connector 222 includes a connector body 2221 and a plug structure 2222. The connector body 2221 has an air blowing channel 2224. The plug structure 2222 is located at one end of the connector body 2221 and extends circumferentially along at least part of the connector body 2221. The plug structure 2222 is inserted into the plug groove 2213. The connector body 2221 passes through the bottom opening of the plug groove 2213.

[0068] In this embodiment, the connecting seat 221 includes at least a seat body 2211. Optionally, the connecting seat 221 may further include a side plate 2212 connected to the seat body 2211 and arranged at an angle to the seat body 2211. The side plate 2212 is slidably connected to the mounting bracket 21 and is drively connected to the driving structure 25. The seat body 2211 is provided with a plug groove 2213. The side wall of the seat body 2211 is provided with a side opening communicating with the plug groove 2213. The bottom wall of the seat body 2211 is provided with a bottom opening communicating with the plug groove 2213. The top wall of the seat body 2211 is provided with a through hole communicating with the plug groove 2213. The insertion structure 2222 of the air nozzle connector 222 can enter and exit the insertion groove 2213 through the side opening of the base 2211, so that the connector body 2221 of the air nozzle 3 structure extends outward from the bottom opening of the base 2211. At this time, the insertion structure 2222 is sandwiched between the bottom wall and the top wall of the base 2211, thereby limiting the air nozzle connector 222 in the height direction, so that the air nozzle 3 structure is stably connected to the connecting base 221.

[0069] See also Figure 6 and Figure 7 In one embodiment, the air nozzle connector 222 further includes a connecting structure 2223, which is set at an angle to the plug-in structure 2222. The connecting structure 2223 is set opposite to the side opening and is connected to the seat 2211.

[0070] This configuration utilizes the connecting structure 2223 to limit the position of the air nozzle connector 222 and restrict the insertion depth of the insertion structure 2222 into the insertion slot 2213. This ensures that the air blowing channel 2224 is accurately aligned with the through hole and the laser transmission channel, guaranteeing that the laser and airflow act accurately on the processing area. The connection between the connecting structure 2223 and the base 2211 also improves the connection strength between the air nozzle connector 222 and the connecting base 221, enhances the structural stability of the base structure 22, and prevents misalignment between the air blowing channel 2224 and the laser transmission channel during processing.

[0071] Optionally, the connection structure 2223 and the base 2211 can be connected by bolts or other locking components 223, or by magnetic connection, adhesive or other connection methods, which are not limited here.

[0072] This utility model also proposes a laser processing device, which includes a main body and a processing module 100. The main body includes a frame, a moving component, and a laser generator. The frame has a processing space, and the moving component is disposed in the processing space. The specific structure of the processing module 100 is as described in the above embodiment. The processing module 100 includes at least two types of air nozzles 3, an air nozzle holder 1, and a processing head assembly 2. The air nozzle holder 1 is fixed on the frame, and the processing head assembly 2 is connected to the moving component. The moving component is used to drive the processing head assembly 2 to move and can drive the processing head assembly 2 to the position of the air nozzle holder 1. The laser generated by the laser generator can be emitted outward through the laser transmission channel of the processing head assembly 2.

[0073] The laser generator can be used to generate laser light for laser processing operations such as laser welding, laser cutting, laser marking, and laser engraving. Optionally, both the processing head assembly 2 and the laser generator can be connected to the moving assembly, keeping them relatively fixed. For example, the processing head assembly 2 can be directly connected to the laser generator, or a mounting bracket can be provided on the moving assembly of the laser processing equipment to mount both the processing head assembly 2 and the laser generator, with both fixed to the bracket. The laser generator's output port can be oriented towards the laser transmission channel of the processing head assembly 2, or the laser can be guided into the laser transmission channel of the processing head assembly 2 using a reflector 2332 and other optical devices. The moving assembly can simultaneously drive both the processing head assembly 2 and the laser generator to different positions for laser processing.

[0074] In some embodiments, the laser generator is fixed in the processing space and the laser is guided to the laser transmission channel of the processing head assembly 2 by the reflector 2332 and other optical devices. In this case, the moving component is only used to drive the processing head assembly 2 to move so as to perform laser processing on the workpiece.

[0075] The processing head assembly 2 is connected to one of the air nozzles 3. The air nozzle 3 that is not currently in use is placed on the air nozzle holder 1, and the air nozzle holder 1 has at least one unused mounting position. When it is necessary to replace the air nozzle 3, the moving component of the laser processing equipment drives the processing head assembly 2 and the laser generator to the position of the air nozzle holder 1, places the air nozzle 3 connected to the processing head assembly 2 in the unused mounting position of the air nozzle holder 1, locks the air nozzle 3 by the locking structure, removes the processing head assembly 2, leaving the air nozzle 3 originally connected to the processing head assembly 2 on the air nozzle holder 1, moves the processing head assembly 2 to the position of the air nozzle 3 to be replaced, connects the processing head assembly 2 to the air nozzle 3, and thus completes the replacement of the air nozzle 3.

[0076] Optionally, the moving component includes a vertically arranged first slide rail and a second slide rail, the second slide rail being slidably mounted on the first slide rail, and the laser generator being slidably mounted on the second slide rail, so that the laser generator can slide along the second slide rail and slide along the first slide rail with the second slide rail.

[0077] Since this laser processing equipment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
