[0041] Currently, the optical path design of some laser devices on the market mostly adopts a single-path laser beam combining design method. However, when designing a high-power laser head, the number of laser generators is relatively large. If only the single-path laser beam combining method is adopted, the size of the laser head in a single direction will be relatively large.
[0042] In order to reduce the risk of the relatively large size of the laser head in a single direction, the present utility model proposes a laser module.
[0043] Please refer to Figures 1 to 4 In an embodiment of the present utility model, the laser module includes a laser matrix component 100, an optical path conversion component 300, and a focusing optical element 200; there are at least two laser matrix components 100, and at least two laser matrix components 100 are arranged in parallel along a first direction; each laser matrix component 100 includes at least two laser generators 111 and at least two first reflectors 112, each first reflector 112 corresponds to at least one laser generator 111, and at least two laser matrix components 100 all output first laser beams along a second direction; there are at least two optical path conversion components 300, and at least two optical path conversion components 300 are correspondingly arranged in the light output paths of at least two laser matrix components 100. Each optical path conversion component 300 is used to receive the first laser beam output by the corresponding laser matrix component 100 and convert the direction, and output a second laser beam along the first direction; the focusing optical element 200 is used to receive the second laser beams output by at least two optical path conversion components 300 and focus them to form a third laser beam.
[0044] The laser matrix component 100 refers to a laser module arranged in a matrix where all optical paths are in the same plane. Each laser module may include a laser generator 111 and a first reflector 112. The first reflector 112 is located on the light-emitting side of the laser generator 111 and is arranged at an angle to the light-emitting direction of the laser generator 111. Then the optical path of the laser module is L-shaped. At least two laser modules with L-shaped optical paths are arranged side by side or opposite to form a matrix, and several L-shaped optical paths are in the same plane. Then the matrix formed by these laser components is the laser matrix component 100.
[0045] Of course, in the technical solution of the present utility model, the optical path of the laser module in the laser matrix component 100 is not limited to L-shaped, and can also be other shapes such as linear and Z-shaped, as long as it can meet the matrix structure where the optical paths of these laser modules are in the same plane, and thus can become the laser matrix component 100 in the technical solution of the present utility model. By setting the laser generator 111, a light source is provided for emitting laser beams. By corresponding each first reflector 112 to at least one laser generator 111, the beam emission direction of the laser generator 111 can be changed, so that the space can be fully utilized, and the space utilization rate of the laser module can be improved as much as possible when setting more first-level array components 110.
[0046] It can be understood that in a laser device, the final beam in the laser module needs to be converged in the focusing optical element 200 and then finally emitted through the focusing optical element 200. By setting at least two optical path conversion components 300, at least two optical path conversion components 300 are correspondingly arranged in the light-emitting paths of at least two laser matrix components 100. Each optical path conversion component 300 is used to receive the first laser beam output by the corresponding laser matrix component 100, convert the direction, and output a second laser beam along the first direction. The focusing optical element 200 receives the second laser beams output by at least two optical path conversion components 300 and focuses them to form a third laser beam, so that it is convenient for at least two groups of laser matrix components 100 to be emitted through the focusing optical element 200. And through the optical path conversion component 300, the first laser beam emitted by the laser matrix component 100 can be turned, so as to change the light-emitting direction so that the second laser beam output by the optical path conversion component can be focused on the focusing optical element 200, thereby reducing the size of the laser module in a single direction and further reducing the volume of the laser module. Among them, the focusing optical element 200 may include one or more lenses.
[0047] When applied to high-power laser devices, the number of laser generators 111 in the laser module will also increase accordingly. The laser module in the technical solution of the present invention includes at least two laser matrix components 100. It can be understood that at least two beams of light can converge into the focusing optical element 200 through the optical path conversion component 300, thereby reducing the situation of arranging multiple laser generators 111 in a single direction, and further reducing the occurrence of the laser module being too large in size in a single direction. Specifically, the optical path conversion component 300 may include several reflectors, or beam combiners, or convex lenses and other lenses, as long as the beams of at least two laser matrix components 100 can be converged into the focusing optical element 200 through the optical path conversion component 300.
[0048] The technical solution of the present invention adopts at least two laser matrix components 100 arranged in parallel along the first direction. Each laser matrix component 100 includes at least two laser generators 111 and at least two first reflectors 112. Each first reflector 112 corresponds to at least one laser generator 111. At least two laser matrix components 100 all output first laser beams along the second direction. Then, under high-power conditions, multiple laser generators 111 can be dispersed in the first direction, avoiding arranging more laser generators 111 in the second direction, and further reducing the size of the laser module in the second direction and avoiding the risk of the laser head being too large in volume. In addition, by setting at least two optical path conversion components 300, at least two optical path conversion components 300 are arranged in the light output paths of at least two groups of laser matrix components 100. Each optical path conversion component 300 is used to receive the first laser beam output by the corresponding laser matrix component 100 and output a second laser beam along the first direction. The focusing optical element 200 is used to receive the second laser beams output by at least two optical paths and focus them to form a third laser beam. Then, the light emitted by at least two groups of laser matrix components 100 can all enter the focusing optical element 200, and further ensure that each beam of light can be emitted through the focusing optical element 200 to ensure the light output effectiveness of each laser matrix component 100. At the same time, the laser module in the present invention can also realize the conversion of the optical path direction, further avoiding the size of the laser module in a single direction and reducing the volume of the laser head.
[0049] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other, and they can be the Z-axis direction, the X-axis direction, and the Y-axis direction respectively. In other embodiments, the first direction, the second direction, and the third direction can also intersect with each other but not be perpendicular.
[0050] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the laser matrix assembly 100 includes at least two laser modules. Each laser generator 111 and a first mirror 112 opposite to the laser generator 111 form a laser module. The light-emitting directions of the laser generators 111 of at least two laser modules are arranged in parallel.
[0051] By making the laser matrix assembly 100 include at least two laser modules, and the light-emitting directions of the laser generators 111 of at least two laser modules are arranged in parallel, the light beams emitted by these at least two laser modules are in the same plane, and it is convenient to convert the light emitted by these at least two laser modules into the focusing optical element 200 through the same optical path conversion assembly 300, thereby reducing the number of the optical path conversion assemblies 300, and further reducing the overall size of the laser module.
[0052] Specifically, the light-emitting directions of the laser generators 111 of at least two laser modules being arranged in parallel may mean that the light-emitting directions of the laser generators 111 of at least two laser modules are the same or opposite. The optical path of each laser module sequentially includes a first optical path emitted by the laser generator 111 and a second optical path reflected by the first mirror 112 along the light-emitting path. Among them, the first optical paths of at least two laser modules are parallel and arranged in opposite directions, and the second optical paths are parallel and arranged in the same direction. Alternatively, the first optical paths and the second optical paths of at least two laser modules are both parallel and arranged in the same direction.
[0053] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the laser matrix assembly 100 includes at least one first laser module 101 and at least one second laser module 102. Each of the first laser module 101 and the second laser module 102 includes a laser generator 111 and a first mirror 112. The first mirror 112 is used to receive the laser beam output by the corresponding laser generator 111 and reflect it to output the laser beam along the first direction. The first laser module 101 and the second laser module 102 are arranged offset in the second direction, and the light-emitting directions of the laser generators 111 in the first laser module 101 and the laser generators 111 in the second laser module 102 are opposite.
[0054] By arranging the laser generators 111 of the first laser module 101 and the laser generators 111 of the second laser module 102 in a dislocation manner in the second direction, and the light-emitting directions of the laser generators 111 in the first laser module 101 and the laser generators 111 in the second laser module 102 are opposite, the space occupied by the laser matrix assembly 100 during arrangement is made more compact, thereby improving the space utilization rate of the laser module, reducing the volume of the laser module, and further reducing the volume of the laser head applying the laser module. For example, when the laser generator 111 in the first laser module 101 is arranged on the front side and emits a laser beam from the front side to the back side, and the first reflector 112 in the first laser module 101 converts the laser beam to emit light to the right side, the laser emitter 111 in the second laser module 102 is arranged on the back side and emits a laser beam from the back side to the front side, and the first reflector 112 in the second laser module 102 is also arranged opposite to the first reflector 112 in the first laser module 101, so as to reflect the laser beam emitted by the laser generator 111 to emit light to the right side as well.
[0055] Furthermore, the laser module further includes a rotatory polarization mirror 400, and the rotatory polarization mirror 400 is arranged on the optical path between the first laser module 101 or the second laser module 102 and the optical path conversion component 300. In Figure 1 and Figure 2 In the illustrated embodiment, the rotatory polarization mirror 400 is arranged between the second laser module 102 and its corresponding optical path conversion component 300 for modulating the laser beam output by the second laser module 102. In other embodiments, the rotatory polarization mirror 400 can also be arranged in the first laser module 101 and its corresponding optical path conversion component.
[0056] It should be noted that when the light-emitting directions of the laser generators 111 in the first laser module 101 and the laser generators 111 in the second laser module 102 are opposite, by arranging the rotatory polarization mirror 400 on the optical path between the first laser module 101 or the second laser module 102 and the optical path conversion component 300, the laser beam emitted by the first laser module 101 or the second laser module 102 can be rotated, so that the processing effects formed by the beams emitted by the first laser module 101 and the second laser module 102 and before entering the optical path conversion component 300 are the same.
[0057] Please refer to Figure 2 As shown, in an embodiment of the present invention, there are at least two first laser modules 101, and the projections of the first reflectors 112 in at least two first laser modules 101 are dislocated or overlapped in the third direction.
[0058] By arranging at least two first reflectors 112 in the first laser module 101 such that their projections perpendicular to the third direction are offset, the laser generators 111 in the multiple first laser modules 101 can be prevented from being blocked by other first reflectors 112 after passing through the first reflectors 112 in their light-emitting directions. Thus, it is ensured that the light beams emitted by the first reflectors 112 in each laser module 101 can be directed towards the optical path conversion component 300. By arranging at least two first reflectors 112 in the first laser module 101 such that their projections perpendicular to the third direction overlap, the overall volume of the laser module can be further reduced. It should be noted that when the projections of at least two first reflectors 112 in the first laser module 101 perpendicular to the third direction overlap, at least one first reflector 112 close to the optical path conversion component 300 has both a reflecting function and a transmitting function. It can transmit the laser beam reflected by the previous first reflector 112 to achieve the function of combining light.
[0059] Please refer to Figure 2 As shown, in an embodiment of the present invention, there are at least two second laser modules 102, and the projections of the first reflectors 112 in the at least two second laser modules 102 in the third direction are offset or overlapped; wherein, the third direction is perpendicular to the first direction and the second direction.
[0060] By arranging at least two first reflectors 112 in the second laser module 102 such that their projections perpendicular to the third direction are offset, the laser generators 111 in the multiple second laser modules 102 can be prevented from being blocked by other first reflectors 112 after passing through the first reflectors 112 in their light-emitting directions. Thus, it is ensured that the light beams emitted by the first reflectors 112 in each laser module 101 can be output to the corresponding optical path conversion component 300. By arranging at least two first reflectors 112 in the second laser module 102 such that their projections perpendicular to the third direction overlap, the size in the second direction can be reduced. It should be noted that when the projections of at least two first reflectors 112 in the second laser module 102 perpendicular to the third direction overlap, at least one first reflector 112 close to the optical path conversion component 300 has both a reflecting function and a transmitting function. It can transmit the laser beam reflected by the previous first reflector 112 to achieve the function of combining light.
[0061] Please refer to in combination with Figure 1 and Figure 2, Further, the laser matrix assembly 100 further includes at least two collimating elements 113, and at least one collimating element 113 is disposed between at least one laser generator 111 and the corresponding first reflector 112. In one embodiment, the number of collimating elements 113 may be the same as the number of laser generators 111, and one laser generator 111 is correspondingly provided with one collimating element 113 and one first reflector 112.
[0062] By disposing at least one collimating element 113 between at least one laser generator 111 and the corresponding reflector, the diverging-angle light beam emitted by at least one laser generator 111 can be collimated into a parallel light beam through at least one collimating element 113, so as to ensure that more light beams can be incident on the corresponding first reflector 112 and are reflected by the first reflector 112 and emitted in the second direction onto the optical path conversion assembly 300, thereby improving the light beam utilization rate and reducing the size of the light spot at the same time.
[0063] Please refer to Figure 1 and Figure 2 , In one embodiment of the present utility model, the output optical paths of at least two optical path conversion assemblies 300 are staggered and parallel, or at least partially overlapped. For example, the output optical paths of at least two optical path conversion assemblies 300 may be completely overlapped or partially overlapped.
[0064] By staggering and parallelizing, or at least partially overlapping, the output optical paths of at least two optical path conversion assemblies 300, it is convenient for the light emitted by at least two laser matrix assemblies 100 to be converged into the focusing optical element 200 through the optical path conversion assembly 300, thereby improving the output of the third high-intensity laser beam by the focusing optical element 200.
[0065] Further, each optical path conversion assembly 300 includes a primary reflection assembly 301 and a secondary reflection assembly 330. The primary reflection assembly 301 is configured to: receive the first laser beam output by the corresponding laser matrix assembly 100 and reflect it, and output a fourth laser beam in the third direction, where the first direction and the second direction are both at an angle with the third direction. The secondary reflection assembly 330 is configured to: receive the fourth laser beam output by the corresponding primary reflection assembly 301 and reflect it, and output a second laser beam in the first direction.
[0066] With such a setting, the laser beam emitted from the laser generator 111 can be converted in at least three different directions, thereby further reducing the size of the laser module in a single direction, and further reducing the volume of the laser module in a single direction.
[0067] Based on the solution that the output optical paths of at least two optical path conversion components 300 are staggeredly parallel or at least partially overlapped, and each optical path conversion component 300 includes a primary reflection component 301 and a secondary reflection component 330. In one example, the second laser beams output by the secondary reflection components 330 in two optical path conversion components 300 are parallel to each other. With such a setting, the difficulty of combining the lights of the two optical path conversion components 300 can be reduced. Specifically, the projections of the secondary reflection components 330 in at least two optical path conversion components 300 are staggeredly arranged in the first direction.
[0068] By staggeredly arranging at least two secondary reflection components 330 in the direction perpendicular to the first direction, the risk that one of the second laser beams output by at least two optical path conversion components 300 blocks the other can be avoided. At this time, the second laser beams output by at least two secondary reflection components 330 are arranged in parallel, and the difficulty of combining the lights can be reduced.
[0069] Based on the solution that the second laser beams output by at least two optical path conversion components 300 are parallel to each other or partially overlapped, and each optical path conversion component 300 includes a primary reflection component 301 and a secondary reflection component 330. In another example, the projections of the secondary reflection components 330 in at least two optical path conversion components 300 are at least partially overlapped in the first direction. With such a setting, the size of the imaging light spot can be reduced.
[0070] Please refer to Figure 1 and Figure 2 , further, the laser matrix component 100 includes at least one first laser module 101 and at least one second laser module 102. The first laser module 101 and the second laser module 102 are opposite and staggeredly arranged. The primary reflection component 301 includes a second reflector 310 and a light combining mirror 320. The second reflector 310 is used to receive the laser beam output by the first laser module 101 and reflect it and output it along the third direction; the light combining mirror 320 is used to receive the laser beam output by the second laser module 102 and reflect it and output it along the third direction, and receive the laser beam output by the second reflector 310 and output it.
[0071] The primary reflection component 301 includes a second reflector 310 and a light combining mirror 320, so that it can be adapted to the scenario with at least two laser modules. In addition, with such a setting, the lights emitted by at least one first laser module 101 and at least one second laser module 102 can coincide through the light combining mirror 302, which is more conducive to all the lights emitted by the two optical path conversion components 300 converging into the focusing optical element 200, and reducing the size of the imaging light spot.
[0072] The present utility model also proposes a laser head 10, as Figure 5As shown, the laser head 10 includes a mounting base 500 and a laser module, and the laser module is mounted on the mounting base 500. For the specific structure of the laser module, refer to the above embodiments. Since the laser head 10 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the laser module is mounted on the mounting base 500.
