Beam expanders are high-precision devices, and their installation and commissioning procedures directly impact the accuracy of the device. Adjustment is particularly crucial when the beam expander is used in conjunction with a laser light source. Existing beam expander commissioning mechanisms typically only allow for parallel movement of the beam expander's position, making it difficult to adjust the beam expander's angle. Summary of the Invention

[0003] The main purpose of the present invention is to provide a beam expander adjustment member, which has the function of adjusting the position and angle of the beam expander at the same time and has a good adjustment effect.

[0004] To achieve the above-mentioned object, the present invention proposes a beam expander adjustment member, comprising:

[0005] A base, wherein a first mounting hole is provided on the base;

[0006] an adjustment platform connected to the base, wherein the adjustment platform is provided with a second mounting hole corresponding to the first mounting hole, and the second mounting hole and the first mounting hole are used for mounting a beam expander; and

[0007] The mounting frame is located at one end of the adjustment platform away from the base, and a plurality of first adjustment bolts are provided on the mounting frame. The plurality of first adjustment bolts are connected to the adjustment platform to adjust the relative position of the mounting frame and the adjustment platform. The mounting frame is used to connect the beam expander.

[0008] Optionally, the mounting bracket has a mounting position for connecting a beam expander, and a plurality of the first adjusting bolts are arranged around the mounting position.

[0009] Optionally, the first adjusting bolt is threadedly connected to the mounting bracket, and an end of the first adjusting bolt abuts against the adjusting platform.

[0012] Optionally, the beam expander adjustment member further includes a first adjustment member, and the first adjustment member includes:

[0013] A first connecting frame connected to the base;

[0014] A second connecting frame is connected to the adjustment platform; and

[0015] The second adjusting bolt is threadedly connected to one of the first connecting frame and the second connecting frame and is rotatably engaged with the other one. The second adjusting bolt extends along the direction of the first guide rail.

[0016] Optionally, the adjustment platform includes:

[0017] A first layer, the first layer is connected to the base, the first layer has a second slide groove, and the second slide groove is arranged at an angle with the first guide rail; and

[0018] The second layer is connected to the mounting frame, and the second layer has a second guide rail adapted to the second slide groove.

[0019] Optionally, the second adjusting member includes:

[0020] a third connecting frame connected to the first layer;

[0027] The technical solution of the present invention uses multiple first adjustment bolts to adjust the relative position and relative angle between the mounting frame and the base. It can be understood that when the multiple adjustment bolts are adjusted synchronously, the adjustment angle between the mounting frame and the base can be guaranteed to remain unchanged while the mounting frame is moved closer to the base or further away from the base.

In addition, by adjusting the position and angle of the collimator in a rotating manner through the first adjustment bolt, it has the characteristics of high adjustment accuracy and good position stability. Furthermore, the provision of the first mounting hole and the second mounting hole, on the one hand, helps to make the center of gravity of the collimator closer to the center of gravity of the collimator adjustment member, making the whole more stable, and on the other hand, can protect the collimator.

[0041] The present invention provides a beam expander adjustment component.

[0042] In the embodiment of the present invention, Figures 1 to 5As shown, the collimator adjustment component includes: a base 100, an adjustment platform 200 and a mounting bracket 300, the base 100 is provided with a first mounting hole 120; the adjustment platform 200 is connected to the base 100, the adjustment platform 200 is provided with a second mounting hole 230 corresponding to the first mounting hole 120, the second mounting hole 230 and the first mounting hole 120 are used for mounting the collimator 600; and the mounting bracket 300 is located at one end of the adjustment platform 200 away from the base 100, the mounting bracket 300 is provided with a plurality of first adjusting bolts 320, and the plurality of first adjusting bolts 320 are connected to the adjustment platform 200 to adjust the relative position of the mounting bracket 300 and the adjustment platform 200, and the mounting bracket 300 is used to connect the collimator 600. When the beam expander 600 is mounted on the beam expander adjustment member, one end of the beam expander 600 is connected to the mounting bracket 300. The beam expander 600 passes through the first mounting hole 120 and the second mounting hole 230 and is capable of displacement and angular deflection within the first mounting hole 120 and the second mounting hole 230. The first adjustment bolt 320 extends in the same direction as the axis of the first mounting hole 120.

[0043] The technical solution of the present invention uses multiple first adjustment bolts 320 to adjust the relative position and angle between the mounting frame 300 and the base 100. It can be understood that when the multiple adjustment bolts are adjusted synchronously, the adjustment angle between the mounting frame 300 and the base 100 can be maintained while the mounting frame 300 can be moved closer to or further away from the base 100. When the multiple adjustment bolts are adjusted asynchronously, the distance between the center of gravity of the mounting frame 300 and the base 100 can be maintained while the relative angle between the mounting frame 300 and the base 100 is changed. It can also achieve a change in both the angle and the distance between the mounting frame 300 and the base 100, resulting in a better adjustment effect. In other words, when the actual installation position of the base 100 deviates from the preset installation position by angular or positional deviation, the beam expander 600 can be adjusted to the preset installation position. In addition, the position and angle of the beam expander 600 can be adjusted by rotating the first adjustment bolt 320, resulting in high adjustment accuracy and good position stability. Furthermore, the provision of the first mounting hole 120 and the second mounting hole 230 not only helps to bring the center of gravity of the beam expander 600 closer to the center of gravity of the beam expander adjustment member, thereby enhancing overall stability, but also protects the beam expander 600.

[0044] Furthermore, in this embodiment, Figure 1 、 Figure 2As shown, the mounting frame 300 has a mounting position for connecting the beam expander 600, and a plurality of first adjustment bolts 320 are arranged around the mounting position. More specifically, the mounting frame 300 is provided with a hole for installing the beam expander, and the beam expander can be fixedly installed in the hole, so that when the mounting frame 300 moves or rotates, the beam expander moves or rotates with the mounting frame 300. The arrangement of the plurality of first adjustment bolts 320 around the mounting position is conducive to making the connection between the mounting frame 300 and the adjustment platform 200 more stable on the one hand, and more convenient to adjust the angle of the mounting frame 300 on the other hand. The plurality of first adjustment bolts 320 are three in this embodiment, but are not limited to three. In other embodiments, the plurality of first adjustment bolts 320 can also be two, four, six, etc. In addition, the plurality of first adjustment bolts 320 can also be set on one side of the mounting position.

[0045] Furthermore, in this embodiment, Figure 1 As shown, the first adjusting bolt 320 is threadedly connected to the mounting bracket 300, and the end of the first adjusting bolt 320 abuts against the adjusting platform 200. That is, when the first adjusting bolt 320 rotates, the relative position between the first adjusting bolt 320 and the adjusting platform 200 remains unchanged, while the relative position between the second adjusting bolt 430 and the mounting bracket 300 changes. This installation method has the advantage of facilitating the installation, removal, replacement, and maintenance of the first adjusting bolt 320. Of course, this embodiment is not limited to the above technical solution. In other embodiments, the first adjusting bolt and the mounting bracket can be rotatably engaged, and the first adjusting bolt and the adjusting platform are threadedly connected. In this case, the relative position between the first adjusting bolt and the mounting bracket remains unchanged, and the relative position between the first adjusting bolt and the adjusting platform is adjustable.

[0046] Furthermore, in this embodiment, Figure 1 As shown, the mounting frame 300 has a protruding connecting post 330 on its surface near the adjustment platform 200, and the adjustment platform 200 has a socket on its surface near the mounting frame 300, in which the connecting post 330 is slidably mounted. The connecting post 330 slides as the mounting frame 300 moves. The connecting post 330 prevents relative rotation between the mounting frame 300 and the base 100, thereby improving the stability of the mounting frame 300. Since the beam expander 600 is a high-precision instrument, the stability of the mounting frame 300 is very important. The configuration of this embodiment can effectively improve the reliability of the operation of the beam expander 600.

[0047] Furthermore, in this embodiment, Figure 1As shown, the surface of the base 100 close to the adjustment platform 200 is provided with a first guide rail 110, and the end of the adjustment platform 200 close to the base 100 is provided with a first slide groove 211, and the first guide rail 110 is adapted to the first slide groove 211. Specifically, the adjustment platform 200 can slide along the first guide rail 110, thereby driving the relative position between the mounting frame 300 and the base 100 to change. The extension direction of the first guide rail 110 is set at an angle to the axial direction of the first mounting hole 120. Of course, it should be pointed out that according to this embodiment, a simple variation of setting the first guide rail 110 on the adjustment platform 200 and setting the first slide groove 211 on the base 100 is also within the scope of protection of this application.

[0048] Furthermore, in this embodiment, Figure 1 As shown, the collimator adjustment member also includes a first adjustment member 400, which includes: a first connecting frame 410, a second connecting member and a second adjustment bolt 430. The first connecting frame 410 is connected to the base 100; the second connecting frame 420 is connected to the adjustment platform 200; the second adjustment bolt 430 is threadedly connected to the first connecting frame 410 and is rotatably engaged with the second connecting frame 420. The second adjustment bolt 430 extends in the direction of the first guide rail 110. By rotating the second adjustment bolt 430, the adjustment platform 200 can be driven to slide along the first guide rail 110. More specifically, an annular groove is provided at the end of the second adjusting bolt 430 connected to the second connecting frame 420, and a corresponding locking hole is provided on the second connecting frame 420. The end of the second connecting frame 420 is penetrated by the locking hole, and the hole wall of the locking hole is arranged in the annular groove. In addition, two nuts can be provided on the second adjusting bolt 430, and the two nuts are respectively located on both sides of the first connecting frame 410. When the second adjusting bolt 430 adjusts the position of the adjusting platform 200 to the desired position, the two nuts can clamp the first connecting frame 410 to achieve a fixed position of the second adjusting bolt 430, thereby ensuring the position stability of the beam expander 600. The second adjusting member 500 of this embodiment is not limited to the above technical solution. In other embodiments, the second adjusting bolt can also be threadedly connected to the second connecting frame and rotatably engaged with the first connecting frame.

[0049] Furthermore, in this embodiment, Figure 1 、 Figure 5As shown, the adjustment platform 200 includes a first layer 210 and a second layer 220. The first layer 210 is connected to the base 100 and has a second slide 212 disposed at an angle to the first guide rail 110. The second layer 220 is connected to the mounting frame 300 and has a second guide rail 221 that mates with the second slide 212. More specifically, a second connecting frame 420 is connected to the first layer 210. Because the first guide rail 110 and the second slide 212 extend in different directions, position adjustment in different directions is possible. The second layer 220 drives relative displacement between the mounting frame 300 and the first layer 210, and the first layer 210 drives relative displacement between the second layer 220 and the base 100, enabling position adjustment of the beam expander 600 on the mounting frame 300 in two directions. Combined with the first adjustment bolt 320, the beam expander 600 can be adjusted in any direction, offering the advantage of high adjustment freedom. Of course, it should be pointed out that, according to this embodiment, a simple variation of disposing the second slide groove 212 in the second layer 220 and disposing the second guide rail 221 in the first layer 210 is also within the protection scope of this application.

[0050] Furthermore, in this embodiment, if Figure 1 As shown, the second adjusting member 500 includes a third connecting frame 510, a fourth connecting frame 520, and a third adjusting bolt 530. The third connecting frame 510 is connected to the first layer 210; the fourth connecting frame 520 is connected to the second layer 220; the third adjusting bolt 530 is threadedly connected to the third connecting frame 510 and is rotatably engaged with the fourth connecting frame 520. Rotating the third adjusting bolt 530 causes the second layer 220 to slide along the second chute 212. The third adjusting bolt 530 extends in the direction of the second chute 212. The specific structure of the second adjusting member 500 is similar to that of the first adjusting member 400 described above, and has the same beneficial effects, so detailed description is omitted here. In other embodiments, the third adjusting bolt may be threadedly connected to the fourth connecting frame and is rotatably engaged with the third connecting frame.

[0051] Furthermore, the first chute 211 and the second chute 212 are dovetail grooves. The dovetail grooves have the advantage of a more stable connection, which helps prevent the first guide rail 110 from dislodging from the first chute 211 and the second guide rail 221 from dislodging from the second chute 212, and has the advantage of a more stable connection. Of course, this embodiment is not limited to the above technical solution. In other embodiments, the first chute and the second chute may be T-slots; or the first chute may be a dovetail groove and the second chute may be a T-slot, which also provide a stable guide rail connection.

[0052] The present invention also proposes a collimator assembly, which includes a collimator 600 and a collimator adjustment member. The specific structure of the subject one is referred to the above embodiment. Since the collimator assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The collimator 600 is connected to the mounting bracket 300. The collimator 600 passes through the first mounting hole 120 and the second mounting hole 230. There is a gap between the collimator 600 and the hole wall of the first mounting hole 120, and there is a gap between the collimator 600 and the hole wall of the second mounting hole 230, which facilitates the collimator 600 to adjust its position in the first mounting hole 120 and the second mounting hole 230.

[0053] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
