Example 1
Referring to fig. 1 and 2, the present embodiment provides an optical assembly for use in a solid-state laser. The optical assembly includes an optical element 100 and a lens mount 200. A photo-curing adhesive layer and a thermosetting adhesive layer are respectively arranged between the optical element 100 and the lens base 200, and the thermosetting adhesive layer covers the photo-curing adhesive layer.
According to the optical component provided by the embodiment of the application, in the process of installing the optical element 100 and the lens seat 200, the relative positions between the optical element 100 and the lens seat 200 can be finely adjusted through the multi-direction adjusting platform 400, so that the optical element 100 is fixed at the set position of the optical path, and then the optical element 100 and the lens seat 200 are respectively fixed by adopting the photo-curing adhesive layer and the thermosetting adhesive layer in sequence in two steps. Because the photo-curing adhesive layer is less affected by the thermal expansion and contraction effect, and the strength of the thermosetting adhesive layer after curing is higher and the service life is longer, the photo-curing adhesive layer and the thermosetting adhesive layer are sequentially used for fixing, so that the problem that the angle and the position of the optical element 100 deviate due to the thermal expansion and contraction effect, thermoplastic deformation and other reasons when the optical component is used can be solved, the connection strength between the optical element 100 and the lens base 200 can be still maintained under the long-time use of the optical component, the problem of optical path misalignment is solved, the laser output power of the solid laser is maintained, and the service life of the solid laser is prolonged.
Before fixing the optical element 100 and the lens holder 200, the lens holder 200 may be first fixed in the solid laser, and then the optical element 100 and the lens holder 200 in the solid laser are sequentially fixed by a photo-curing adhesive layer and a thermosetting adhesive layer, so as to improve the accuracy of the angle and the position of the optical element 100 in the solid laser.
Wherein the optical element 100 includes, but is not limited to, a lens, a polarizing element, a crystal.
The photo-curing glue layer is glue which is irradiated by light with corresponding wavelength and is subjected to curing reaction.
As shown in fig. 1 and 2, in the above embodiment, optionally, the optical assembly further includes a connector 300 disposed on the lens holder 200, the connector 300 is located between the lens holder 200 and the optical element 100, a photo-curing adhesive layer and a thermosetting adhesive layer are respectively disposed between the connector 300 and the optical element 100, and the coefficient of thermal expansion and contraction of the connector 300 is between the coefficients of thermal expansion and contraction of the optical element 100 and the lens holder 200.
Specifically, during installation, the connecting piece 300 and the lens base 200 may be fixed by gluing, and then the optical element 100 and the connecting piece 300 may be fixed by sequentially setting the photo-curing adhesive layer and the thermosetting adhesive layer in steps. Since the coefficient of thermal expansion and contraction of the connecting piece 300 is between the coefficients of thermal expansion and contraction of the optical element 100 and the lens base 200, when the optical assembly is expanded by heating, the arrangement mode of the connecting piece 300 can improve the phenomenon of cracking between the optical element 100 and the lens base 200 caused by different degrees of thermal expansion, reduce the possibility of cracking between the optical element 100 and the connecting piece 300 and between the lens base 200 and the connecting piece 300 caused by overlarge differences of the coefficients of thermal expansion, and reduce the possibility of angular and positional offset of the optical element 100, thereby improving the problem of optical path misalignment, maintaining the laser output power of the solid laser and prolonging the service life of the solid laser. Wherein, the larger the coefficient of thermal expansion and contraction is, the larger the degree of volume expansion or contraction is.
As shown in fig. 2, a fixing groove 210 may be formed on a surface of the lens base 200 facing the optical element 100, the connecting piece 300 may be fixed in the fixing groove 210, and the fixing groove 210 may limit the connecting piece 300, thereby improving alignment accuracy.
When the optical element 100 is made of a glass material and the lens holder 200 is made of a metal material such as an aluminum alloy, the connector 300 may be made of a ceramic material, and a better adhesion effect may be formed between the ceramic material and the glass material and between the ceramic material and the metal material, respectively, so that the problem of weak adhesion between the glass material and the metal material may be improved.
In the above embodiment, optionally, the photo-curing adhesive layer is an ultraviolet adhesive; and/or the thermosetting adhesive layer is AB adhesive.
Specifically, when the photo-curing adhesive layer is an ultraviolet adhesive, the ultraviolet adhesive can be disposed between the optical element 100 and the lens base 200, and then the optical element 100 and the lens base 200 are fixed at normal temperature by means of ultraviolet light irradiation, and the cured ultraviolet adhesive is less affected by thermal expansion and contraction, so that the problem that the angle and the position of the optical element 100 are deviated due to heating between the optical element 100 and the lens base 200 in the use process of the solid laser can be improved. Wherein, since the ultraviolet glue has a certain transparency, the ultraviolet light emitted from the ultraviolet lamp can be irradiated to the ultraviolet glue between the optical element 100 and the lens base 200 through the surface of the ultraviolet glue, thereby realizing rapid and sufficient curing. When the thermosetting adhesive layer is an AB adhesive, the AB adhesive is formulated according to a ratio of an a (main liquid) and a B (curing agent), after the AB adhesive is blended, chemical reaction occurs naturally, and the AB adhesive is cured along with time, and belongs to the thermosetting adhesive layer, the AB adhesive can be arranged between the optical element 100 and the lens base 200 and covers the cured photo-curing adhesive layer, and because the structural strength of the AB adhesive is relatively high and the service life of the AB adhesive is relatively long, the problems of relatively low structural strength and relatively low service life of the photo-curing adhesive layer can be overcome, and therefore, the ultraviolet adhesive and the AB adhesive are mutually matched and fix the optical element 100 and the lens base 200 respectively, and the respective advantages of the two adhesives can be exerted to a certain extent and the respective disadvantages can be avoided.
Example two
As shown in fig. 3 and 4, another embodiment of the present application provides an optical component fixing method, including:
acquiring the lens base 200 and the optical element 100, fixing the optical element 100 on a fixture 490 of the multi-directional adjustment platform 400, and adjusting the relative position between the optical element 100 and the lens base 200 through the multi-directional adjustment platform 400;
specifically, the lens base 200 may be fixed in the solid-state laser, then the optical element 100 is fixed on the fixture 490 of the multi-directional adjustment platform 400, and then the multi-directional adjustment platform 400 is manipulated to adjust the relative position between the optical element 100 and the lens base 200, so that the optical element 100 is fixed at the set position of the optical path.
A photo-curing adhesive layer is arranged between the optical element 100 and the lens base 200, and the photo-curing adhesive layer is irradiated by a photo-curing lamp to be cured, so that the relative position between the optical element 100 and the lens base 200 is primarily fixed;
specifically, a photo-curing glue layer is coated between the optical element 100 and the lens base 200, and then the photo-curing glue layer is irradiated by a photo-curing lamp to be cured, so that the optical element 100 and the lens base 200 are primarily fixed under the fixation of the clamp 490 at normal temperature, the on-site in-situ debugging can be realized, and the environmental conditions and the curing requirements required by the primary curing are reduced.
A thermosetting adhesive layer is further disposed between the optical element 100 and the lens base 200 to reinforce the optical element 100 and the lens base 200.
Specifically, since the structural strength and the service life of the cured thermosetting adhesive layer are long, the use of the thermosetting adhesive layer to reinforce the optical element 100 and the lens holder 200 can improve the connection strength between the optical element 100 and the lens holder 200. In addition, the multi-direction adjusting platform 400 still limits the optical element 100 and the lens base 200 in the curing process of the thermosetting adhesive layer, so that the angle and the position accuracy of the optical element 100 after the curing of the thermosetting adhesive layer and the photo-curing adhesive layer can be improved. The heating and curing process of the thermosetting adhesive layer can be realized in a high-low temperature box, and compared with the primary curing process of the photo-curing adhesive layer, the requirement of the condition required by the heat curing process is higher, so that the heat curing process with higher curing condition is arranged after the primary curing process with lower curing condition, the relative position adjusting process of the optical element 100 and the lens seat 200 can be prevented from being in the heating and curing process, the operation difficulty of heating and curing and the difficulty of adjusting the relative positions of the optical element 100 and the lens seat 200 are reduced, and the operation of workers is facilitated.
In the foregoing embodiment, optionally, the optical component fixing method further includes:
separating the clamp 490 from the optical element 100;
and simultaneously heating the optical element 100, the lens holder 200, the optical cement layer and the thermosetting cement layer to remove stress among the optical element 100, the lens holder 200, the optical cement layer and the thermosetting cement layer.
Specifically, the optical element 100 and the clamp 490 may be separated first, and then the optical assembly is placed in a heating furnace for heating, and since the photo-curing adhesive layer and the thermosetting adhesive layer between the optical element 100 and the lens holder 200 are cured and the photo-curing adhesive layer is less affected by the thermal expansion and contraction effect, the photo-curing adhesive layer still can stably fix the relative position between the optical element 100 and the lens holder 200 during the heating process, and thus, when the thermal stress between the optical element 100, the lens holder 200, the photo-curing adhesive layer and the thermosetting adhesive layer is removed, the problem that the relative position between the optical element 100 and the lens holder 200 is changed after the thermal stress is removed can be improved, thereby improving the angle and the positional accuracy of the optical element 100 after the stress is removed. And the mode of removing the thermal stress can enable the optical component to reduce the influence of structural stress and thermal deformation on the light path when the optical component is used subsequently.
Wherein, the thermal stress refers to the stress generated by the fact that the object cannot expand and contract completely and freely due to external constraint and mutual constraint among the internal parts when the temperature is changed.
As shown in fig. 4, in the above embodiment, optionally, the fixing the optical element 100 on the fixture 490 of the multi-directional adjustment platform 400 includes:
the fixture 490 of the multi-directional adjustment platform 400 is provided with a negative pressure hole 491, and the negative pressure hole 491 is used for providing negative pressure to adsorb the optical element 100 on the fixture 490.
Specifically, when in use, the negative pressure hole 491 of the fixture 490 of the multidirectional adjustment platform 400 can be communicated with a negative pressure pipeline or a negative pressure device, so that negative pressure is formed in the negative pressure hole 491, and suction force can be generated by the negative pressure, so that the optical element 100 is adsorbed on the fixture 490, thereby realizing quick connection or quick separation between the optical element 100 and the fixture 490, and improving the processing efficiency.
As shown in fig. 4, a limiting protrusion may be disposed on a surface of the fixture 490 facing the optical element 100, and the limiting protrusion may have an L shape, so as to limit the optical element 100 in two directions at the same time.
As shown in fig. 3 and 5, in the above embodiment, optionally, the adjusting the relative position between the optical element 100 and the lens base 200 by the multi-directional adjustment platform 400 includes:

the multi-directional adjustment stage 400 drives the optical element 100 to rotate in directions perpendicular to the X-axis direction and/or the Y-axis direction and/or the Z-axis direction, respectively.
Specifically, the multi-directional adjustment platform 400 may include a fixture 490, an X-axis linear guide 410, a Y-axis linear guide 420, an X-axis sliding platform 430, a Y-axis sliding platform 440, a Z-axis sliding platform 450, an X-axis rotating platform 460, a Y-axis rotating platform 470, and a Z-axis rotating platform 480, wherein the Y-axis linear guide 420 is disposed on a first slide 411 of the X-axis linear guide 410, an X-axis sliding platform 430, a Y-axis sliding platform 440, a Z-axis sliding platform 450, an X-axis rotating platform 460, a Y-axis rotating platform 470, and a Z-axis rotating platform 480 are sequentially stacked on a second slide 421 of the X-axis linear guide 410 from bottom to top, and the fixture 490 is connected to a rotating portion of the Z-axis rotating platform 480.
The X-axis linear guide 410 and the X-axis sliding platform 430 can respectively implement coarse adjustment and fine adjustment of the jig 490 in the X-axis direction. The Y-axis linear guide 420 and the Y-axis sliding platform 440 may respectively implement coarse and fine adjustments of the fixture 490 in the Y-axis direction. The Z-axis rotation stage 480 may enable fine adjustment of the clamp 490 in the Z-axis direction. The X-axis rotating platform 460, the Y-axis rotating platform 470, and the Z-axis rotating platform 480 may respectively implement circumferential rotation of the fixture 490 along the X-axis, circumferential rotation along the Y-axis, and circumferential rotation along the Z-axis.
Thus, the multi-directional adjustment platform 400 can realize sliding of the optical element 100 in three directions and rotation of the optical element 100 in three directions, respectively, thereby more precisely adjusting the angle and position of the optical element 100.
In addition, as shown in fig. 6, the X-axis linear guide 410 and the Y-axis linear guide 420 may be provided with locking assemblies 412, respectively, and the locking assemblies 412 may fix the positions of the first slider 411 and the second slider 421, respectively.
In the above embodiment, optionally, before adjusting the relative position between the optical element 100 and the lens base 200 by the multi-directional adjustment platform 400, the method includes: mounting the mirror mount 200 in the housing of the solid state laser;
the above optical component fixing method further includes: the optical path detection is performed on the optical element 100 in the case of the solid-state laser.
Specifically, the lens base 200 may be first installed in the housing of the solid-state laser, and then the optical element 100 in the housing of the solid-state laser is subjected to optical path detection, so as to screen out an optical component with an unqualified optical path.
