In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0040] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:
[0041] refer to Figures 1 to 6 According to the laser head of the embodiment of the first aspect of the present application, it includes an adjustment body 100 and a beam adjustment mechanism 200. The adjustment body 100 is provided with a laser channel 110, a light inlet 120 and a plurality of light outlets 130. The light inlet 120 is located at one end of the laser channel 110 and communicates with the laser channel 110, and each light outlet 130 is located at the other end of the laser channel 110. The beam adjustment mechanism 200 is detachably connected to the adjustment body 100, and the beam adjustment mechanism 200 is placed in the laser channel 110, and can change the transmission direction of the laser in the laser channel 110, so that the laser in the laser channel 110 is emitted from one of the light outlets 130. Therefore, the laser head can select different light outlets 130 for light emission according to the needs in different scenarios, which is beneficial to improving the flexibility of the use of the laser head.
[0042] Specifically, the laser enters the laser channel 110 from the light inlet 120, and the beam adjustment mechanism 200 is arranged in the laser channel 110. The beam adjustment mechanism 200 is used to reflect the laser to change the transmission direction of the laser in the laser channel 110. It should be understood that in the laser channel 110, the beam adjustment mechanism 200 can change the laser transmission direction multiple times. Under the action of the beam adjustment mechanism 200, any one of the light outlets 130 can be selected to emit the laser according to the needs of the working scene. The laser is emitted from different light outlets 130 so that the laser head has different light emission modes. When the laser head emits laser, except for the light outlet 130 used to emit laser, other light outlets 130 should remain sealed, which is beneficial to prevent dust and other debris from entering the inside of the laser channel 110 through other light outlets 130, effectively ensuring the cleanliness of the optical lens.
[0043] It should be noted that the working scenarios of the laser head include but are not limited to laser edge banding, laser cleaning of a platform or a manipulator, and handheld laser cleaning, and the beam adjustment mechanism 200 can change the transmission direction of the laser in the laser channel 110 by adjusting the position relative to the adjustment body 100 and / or changing its own form. It should be understood that the adjustment of the position of the beam adjustment mechanism 200 relative to the adjustment body 100 is achieved by disassembly and assembly, and the disassembly and assembly of the beam adjustment mechanism 200 on the adjustment body 100 causes the position of each component on the beam adjustment mechanism 200 to change relative to the adjustment body 100, that is, the form of the beam adjustment mechanism 200 itself changes.
[0044] refer to Figures 4 to 6 In some embodiments, the laser channel 110 includes a first through section 111 and a second through section 112 that are connected to each other. The first through section 111 is extended along a first direction, and the second through section 112 is extended along a second direction. The first direction and the second direction are perpendicular to each other. A first through hole 1121, a second through hole 1122, and a third through hole 1123 are provided on the inner wall of the second through section 112. One end of the first through hole 1121 is connected to the second through section 112. A first light outlet 131 is formed at the other end of the first through hole 1121. The axial direction of the first through hole 1121 is parallel to the second direction. One end of the second through hole 1122 is connected to the second through section 112, and a second light outlet 132 is formed at the other end of the second through hole 1122. The axial direction of the second through hole 1122 is parallel to the first direction. One end of the third through hole 1123 is connected to the second through section 112, and a third light outlet 133 is formed at the other end of the third through hole 1123. The axial direction of the third through hole 1123 is perpendicular to the first direction and the second direction. Thus, the laser head has a first mode of emitting light through the first light outlet 131, a second mode of emitting light through the second light outlet 132, and a third mode of emitting light through the third light outlet 133.
[0045] Specifically, the first light outlet 131, the second light outlet 132 and the third light outlet 133 are oriented perpendicular to each other, the light inlet 120 is arranged on the first through section 111, and the laser enters the first through section 111 through the light inlet 120. The beam adjustment mechanism 200 reflects the laser at the connection between the first through section 111 and the second through section 112 to change the transmission direction of the laser. The laser in the first through section 111 is reflected into the second through section 112 under the action of the beam adjustment mechanism 200, that is, the transmission direction of the laser is changed from transmission along the first direction to transmission along the second direction, so that the laser can be emitted from the first light outlet 131. At this time, the laser head is in the first mode, and the beam adjustment mechanism 200 can also be simultaneously arranged at the position of the second through hole 1122 or the third through hole 1123 of the second through section 112 to further reflect the laser and change the transmission direction of the laser, so that the laser can be emitted from the second light outlet 132 or the third light outlet 133, which is beneficial to meet the needs of different laser operation scenarios.
[0046] refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, in the first mode, the beam adjustment mechanism 200 includes a first lens structure 210, which is arranged at the connection between the first through section 111 and the second through section 112. The first lens structure 210 is used to reflect the laser in the first through section 111 into the second through section 112, so that the laser is emitted from the first light outlet 131. The first lens structure 210 has a galvanometer 211, which can reflect the laser, and the galvanometer 211 can reciprocate around a rotation axis within a certain angle range, so that the laser produces a swinging effect. The reflection accuracy of the galvanometer 211 is high, and the laser is reflected only by the galvanometer 211, which is beneficial to ensure the accuracy of laser edge sealing and is suitable for laser edge sealing working scenarios.
[0047] refer to Figure 3 and Figure 4In some embodiments, in the second mode, the beam adjustment mechanism 200 includes a first lens structure 210 and a second lens structure 220. The first lens structure 210 is arranged at the connection between the first through section 111 and the second through section 112. Along the second direction, the second lens structure 220 is arranged at the end of the second through section 112 away from the first lens structure 210. The first lens structure 210 is used to reflect the laser in the first through section 111 to the second lens structure 220, and then reflect the laser out from the second light outlet 132 through the second lens structure 220. Two changes of direction are generated during the laser reflection process. The first lens structure 210 has a galvanometer 211, and the second lens structure 220 has a reflector. The galvanometer 211 has higher reflection accuracy than the reflector, and the reflector has higher reflectivity than the galvanometer 211. Therefore, the laser in the first through section 111 is first reflected onto the reflector through the galvanometer 211, and then the laser is reflected out from the second light outlet 132 through the reflector. The galvanometer 211 is used to ensure the reflection accuracy of the laser, and the reflector is used to ensure the reflectivity of the laser. Therefore, the laser emitted from the second light outlet 132 can better take into account the accuracy and range of the laser beam. At the same time, as the galvanometer 211 reciprocates around an axis within a certain angle, the laser emitted from the second light outlet 132 has a swinging effect, which is suitable for the working scene of platform or robot laser cleaning, and is beneficial to ensuring the laser cleaning effect.
[0048] It should be noted that the axial direction of the second through hole 1122 is set parallel to the first direction, so that the opening of the second light outlet 132 is also facing the first direction, that is, when the laser passes through the laser head, the transmission direction of the laser entering the laser channel 100 and leaving the laser channel 100 does not change. At the same time, the part used for clamping on the adjustment body 100 is also set to a plane parallel to the first direction. When the platform or manipulator moves along a straight line or a compound motion composed of multiple straight lines, the transmission direction of the laser can be parallel or perpendicular to the movement direction of the platform or manipulator, which is beneficial to ensure the accuracy of laser cleaning.
[0049] refer to Figure 5 and Figure 6In some embodiments, in the third mode, the beam adjustment mechanism 200 includes a first lens structure 210 and a second lens structure 220. The second lens structure 220 is arranged at the connection between the first through section 111 and the second through section 112. Along the second direction, the first lens structure 210 is arranged at one end of the second through section 112 away from the second lens structure 220. The second lens structure 220 is used to reflect the laser in the first through section 111 to the first lens structure 210. The first lens structure 210 is used to reflect the laser out of the third light outlet 133. The first lens structure 210 includes a galvanometer 211, and the second lens structure 220 includes a reflector. In the third mode, the laser is first reflected by the reflector and then reflected by the galvanometer 211. Compared with the second mode, the galvanometer 211 can reflect the laser from the reflector with a higher precision, so that the laser emitted from the third light outlet 133 has a higher precision and is suitable for the scene of handheld laser cleaning. It should be understood that the cleaning accuracy of a handheld laser head is lower than that of a platform or a manipulator. Therefore, the third mode is suitable for working scenarios that require higher laser accuracy than the second mode.
[0050] It should be noted that laser cleaning and laser edge banding have different requirements for laser precision. Laser edge banding has higher requirements for laser precision, and the reflection precision of the galvanometer 211 is higher than that of the reflector. Therefore, in the first mode, only the galvanometer 211 is used to reflect the laser, which is beneficial to ensure the precision of the laser, while taking into account the swing effect of the laser beam to meet the working requirements of laser edge banding. In the second mode and the third mode, a combination of the galvanometer 211 and the reflector is used for laser cleaning to obtain a larger coverage range and ensure good laser uniformity within the cleaning range. Compared with the platform or the manipulator, the operation precision of the handheld laser head is lower, so it is necessary to set the third mode of first reflecting through the reflector and then reflecting through the galvanometer 211 to apply to the manual operation scene. At the same time, because the movement precision of the platform or the manipulator is higher, correspondingly, a laser with lower precision than the third mode can be set for cleaning to ensure the coverage of the laser in the second mode.
[0051] refer to Figure 6In some embodiments, the first lens structure 210 includes a galvanometer 211 disposed in the laser channel 110 and a driving unit 212 connected to the galvanometer 211. The driving unit 212 is used to drive the galvanometer 211 to rotate, so that the galvanometer 211 reciprocates around a rotation axis within a certain angle range, so that the laser reflected by the galvanometer 211 has a swinging effect. The driving unit 212 can be a motor, and the galvanometer 211 is connected to the rotating part of the motor, that is, the rotating shaft connected to the rotor. The second lens structure 220 can be a reflector. The first lens structure 210 and the second lens structure 220 are independent of each other. By relatively adjusting the main body 100 to disassemble and assemble the first lens structure 210 and the second lens structure 220, they can be switched between the first mode, the second mode and the third mode, effectively meeting different laser operation requirements.
[0052] refer to Figures 4 to 8 In some embodiments, the laser head further includes an installation module 300, which is detachably connected to the adjustment body 100. The installation module 300 includes an installation body 310. The installation body 310 is provided with an installation cavity 311, a cavity inlet 312 and a cavity outlet 313. The cavity inlet 312 and the cavity outlet 313 are both connected to the installation cavity 311. The installation cavity 311 is used to install a focusing mirror. The cavity inlet 312 is configured to be connected to any light outlet 130. The installation module 300 is used to receive the laser reflected by the beam adjustment mechanism 200, so that the laser is converged by the focusing mirror and then emitted from the cavity outlet 313. The setting of the installation module 300 is beneficial to making the laser more concentrated.
[0053] refer to Figures 1 to 6 In other embodiments, the laser head includes the above-mentioned first mode, second mode and third mode. In the first mode, the mounting module 300 is installed at the first light outlet 131, in the second mode, the mounting module 300 is installed at the second light outlet 132, and in the third mode, the mounting module 300 is installed at the third light outlet 133. Thus, the mounting module 300 can change the connection position with the adjustment body 100 according to different modes of the laser head, which is beneficial to better meet the operation requirements of laser edge sealing or cleaning.
[0054] refer to Figure 7 and Figure 8In some embodiments, the mounting module 300 further includes a plurality of mounting parts 320. A plurality of mounting openings 314 are provided on the side wall of the mounting body 310. The mounting openings 314 are connected to the mounting cavity 311. The mounting parts 320 are inserted into the mounting openings 314 and are detachably connected to the mounting body 310. The mounting parts 320 are used to mount lenses, which may be focusing lenses, protective lenses, and the like. Along the transmission direction of the laser, the protective lenses should be mounted on the mounting parts 320 near the cavity outlet 313. The protective lenses can effectively prevent dust and other debris in the external environment from entering the interior of the laser head, so that the lenses in the laser head remain clean. The mounting parts 320 are detachably connected to the mounting body 310 so that each mounting part 320 can be individually withdrawn from the mounting body 310, which is convenient for replacing or cleaning the focusing lenses, protective lenses, and the like mounted on the mounting parts 320.
[0055] refer to Figures 4 to 8 In some embodiments, an air inlet channel 140 is provided on the adjustment body 100, and the mounting module 300 further includes a nozzle structure 330, on which a nozzle opening 331 is provided, and the nozzle structure 330 is connected to the cavity outlet 313, and the nozzle opening 331 gradually shrinks in a direction away from the cavity outlet 313, and the air inlet channel 140 is used to connect the gas source and the nozzle opening 331, and the gas source flows from the air inlet channel 140 to the nozzle opening 331, and sprays air to the outside at the nozzle opening 331 to form an air curtain, which is beneficial to further prevent external smoke and dust from entering the laser head.
[0056] It should be understood that the nozzle opening 331 gradually shrinks in the direction away from the cavity outlet 313, and the direction of the airflow generated by the gas source also flows in the direction away from the cavity outlet 313. The setting of the nozzle opening 331 structure effectively increases the flow rate of the airflow and effectively improves the airflow isolation effect of the laser head.
[0057] refer to Figures 1 to 8In some embodiments, the first mode, the second mode and the third mode can be switched arbitrarily, that is, any mode can be switched to one of the other two modes. Taking the first mode as an example, in the first mode, the adjustment body 100 is connected with the first lens structure 210, the first lens structure 210 is located at the connection between the first through section 111 and the second through section 112, and the installation module 300 is connected to the first light outlet 131. The first mode is suitable for the working scene of laser edge sealing. On the basis of the first mode, along the second direction, by installing the second lens structure 220 at one end of the second through section 112 away from the first lens structure 210, and disassembling the installation module 300 from the first light outlet 131 to the second light outlet 132, the switching from the first mode to the second mode is realized. In addition, on the basis of the first mode, the first lens structure 210 is removed, and the second lens structure 220 is installed at the connection between the first through section 111 and the second through section 112, and the removed first lens structure 210 is installed at the end of the second through section 112 away from the second lens structure 220, and the installation module 300 is disassembled and assembled from the first light output port 131 to the third light output port 133, thereby realizing the switching from the first mode to the third mode.
[0058] It should be noted that in order to ensure the sealing of the laser head, sealing strips can be set between the various connecting structures of the laser head to seal the laser head. The laser head can also be made of aluminum alloy, and a cooling inlet pipe and a cooling outlet pipe are connected to the laser head. The cooling liquid is circulated on the laser head through the cooling inlet pipe and the cooling outlet pipe, and the cooling liquid will not enter the laser channel 110 of the laser head. The cooling liquid is used to cool the laser head, which effectively improves the problem of heat damage to the lens in the laser head.
[0059] refer to Figures 1 to 8 According to the laser processing equipment of the second aspect embodiment of the present application, it includes a laser emitting device and a laser head in any of the above embodiments, the laser head is connected to the laser emitting device, the laser emitting device is used to emit laser into the laser channel 110, the laser is changed in the transmission direction by the beam adjustment mechanism 200 in the laser channel 110 and then emitted from any light outlet 130, which is used for laser edge sealing, laser cleaning and other operations.
[0060] Specifically, the laser emitting device emits laser into the laser channel 110 through the laser optical fiber. The laser enters the laser channel 110 through the light inlet 120. A collimating mirror structure can be installed at the light inlet 120 to collimate the laser, which is beneficial to ensure the parallelism of the laser beam.
