The embodiments described below are exemplary only, and are not to be taken in a limiting sense. Rather, embodiments of the present application encompass all variations, modifications and alternatives that fall within the spirit and scope of the appended claims.

[0050] Optical lens adjustment requires special adjustment devices. In the prior art, conventional optical lens adjustment devices use mechanical assembly methods, and the displacement and angle of the optical lens are achieved by using spacers or screws to press against the lens and repeatedly adjusting the distance. After the position is adjusted, the positions of the spacers and screws need to be glued and cured. The number of gluing is large, and the places of gluing are not very firm. If the optical lens needs to be accurately adjusted, the adjustment device needs to have high mechanical processing precision, which is costly.

[0051] An optical lens adjustment device according to an embodiment of the present application is described below with reference to the attached drawings. Figure 1 is a front overall structure schematic diagram of an optical lens adjustment device according to an embodiment of the present application.

[0052] Referring to Figure 1 A first aspect of an embodiment of the present application proposes an optical lens adjustment device, which comprises a lens mounting part 1, a height indicating part 2, a horizontal rotation adjusting part 3, a height locking part 4, a horizontal displacement adjusting part 5, and a pitch adjusting part 6. Among them:

[0053] The lens mounting part 1 is used to fix the optical lens 7 inside it. The types of optical lenses that can be used by the adjustment device of the present embodiment are various, such as: stripe mirror, polarizer, fast-axis collimating mirror, slow-axis collimating mirror, homogenizing sheet, etc.

[0054] The height indicating part 2 is used to adjust and indicate the height of the optical lens 7. The height direction is consistent with the vertical axis direction. In an embodiment, the height indicating part 2 is detachably connected with the lens mounting part 1, and the height indicating part 2 is mounted on one side of the lens mounting part 1. The height indicating part 2 is provided with scale lines for indicating the height of the optical lens 7.

[0055] The height locking part 4 is used to lock the position of the lens mounting part 1 after the optical lens 7 is adjusted to the required height. In an embodiment, the height locking part 4 is detachably connected with the lens mounting part 1, and the height locking part 4 is mounted on the other side of the lens mounting part 1.

[0056] The horizontal rotation adjusting part 3 is located below the lens mounting part 1, and the horizontal rotation adjusting part 3 is used to adjust the horizontal angle between the side surface of the optical lens 7 and the side surface of the horizontal rotation adjusting part 3. In other words, the horizontal rotation adjusting part 3 can rotate a certain angle around the vertical axis to adjust the placement angle of the optical lens 7. In an embodiment, the two sides of the horizontal rotation adjusting part 3 are respectively connected with the height indicating part 2 and the height locking part 4.

[0057] The horizontal displacement adjusting part 5 is located below the horizontal rotation adjusting part 3, and is used to adjust the relative displacement of the horizontal rotation adjusting part 3 and the pitch adjusting part 6 projected on the reference surface, so as to adjust the placement position of the optical lens 7 on the reference surface. The relative displacement of the reference surface includes two dimensions, one is moving along the horizontal axis direction, and the other is moving along the vertical axis direction.

[0058] The pitch adjusting part 6 is located below the horizontal displacement adjusting part 5, and is used to adjust the pitch angle of the bottom surface of the horizontal displacement adjusting part 5 and the reference surface, so as to adjust the pitch angle of the optical lens relative to the reference surface. The pitch adjusting part 6 is provided with scale lines for indicating the pitch angle. In an embodiment, the pitch adjusting part 6 can adopt an angular displacement slide.

[0059] According to the optical lens adjusting device provided by the embodiment of the present application, by setting the height indicating part and the height locking part, the height indicating part and the height locking part are used in cooperation to realize the rapid adjustment and indication of the optical lens in the height direction, the height and the pitch angle of the optical lens can be quantitatively controlled, the operation is convenient, and the adjustment efficiency is improved. The optical lens adjusting device can provide the adjustment of the optical lens in five dimensional directions of the horizontal axis direction, the vertical axis direction, the vertical axis direction, the rotation around the vertical axis and the pitch angle, avoids the adjustment mode of changing the thickness of the gasket in the prior art, has a wide range of use, high adjustment precision and simple operation.

[0060] In some embodiments, in combination with Figure 1 , Figure 2As shown, the lens mounting part 1 includes a frame 11 and a fixing block 12. An optical lens 7 is mounted inside the frame 11, and the frame 11 has first mounting holes 18 on both sides. The fixing block 12 has a first opening 17 corresponding to the first mounting holes 18. First fasteners 14 are installed in the first opening 17 and the first mounting holes 18 to secure the optical lens 7 within the frame 11. The position of the first mounting holes 18 can be designed according to actual needs. Figure 2 In the implemented example, the first mounting holes 18 are designed on the upper and lower sides of the frame 11. The fixing blocks 12 are located on the same surface of the frame 11. After the first fastener 14 is tightened, the fixing blocks 12 can press against the optical lens 7 to prevent the optical lens 7 from shifting or falling off. In one example, four notches 13 are provided at the four corners of the inner side of the frame 11. The notches 13 are used for adhesive application to reinforce the optical lens 7. The inner circumferential contour of the notch 13 can be semi-circular or other shapes. In this example, there are only these four notches for adhesive application, which reduces the number of adhesive application points compared to the prior art where gaskets and screws also require adhesive application for curing.

[0061] In some embodiments, combined with Figures 1-4 As shown, the height indicator 2 includes a support block 22 and an adjusting bolt 24. The support block 22 is fixedly connected to the frame 11, and has a screw hole 21 in the middle. Optionally, the bottom surface of the support block 22 is flush with the bottom surface of the frame 11. The support block 22 and the frame 11 are integrally formed. The adjusting bolt 24 can be a bolt. The upper side of the screw portion of the adjusting bolt 24 is threaded to the screw hole 21, and the lower side of the screw portion of the adjusting bolt 24 is threaded to the horizontal rotation adjustment part 3. An upper retaining ring 23 is installed between the head of the adjusting bolt 24 and the support block 22, and scale lines are provided on the screw portion of the adjusting bolt 24. The slot in the head of the adjusting bolt 24 can be straight, cross-shaped, or other shaped. A lower retaining ring 25 is installed at the position where the lower side of the adjusting bolt 24 intersects with the bottom surface of the support block 22. When the adjusting bolt 24 is rotated, the upper retaining ring 23 and the lower retaining ring 25 lock the support block 22, causing the frame 11 to move up and down synchronously. At the junction of the adjusting bolt 24 and the horizontal rotation adjustment part 3, the scale lines indicate the current height of the optical lens 7. The adjusting bolt enables rapid and precise height adjustment.

[0062] In some embodiments, the horizontal rotation adjustment part 3 comprises an adapter platform 31. The middle part of the adapter platform 31 has a groove 32, and two circular-arc notches 33 are disposed through the groove 32 and symmetrically distributed along the two sides of the adapter platform 31. It is to be noted that the inner arc surfaces of the two circular-arc notches 33 are opposite. A second fastener 34 is disposed in the circular-arc notches 33, and the second fastener 34 is used to fix the adapter platform 31 and the horizontal displacement adjustment part 5. In the state without being screwed, the screw rod part of the second fastener 34 can move along the arc direction of the circular-arc notches 33. The groove 32 is used to reduce the height of the head of the second fastener 34 so as to avoid interference with the frame 11. The circular-arc notches are easy to adjust and fix the placement angle of the optical lens.

[0063] In some embodiments, the height locking part 4 comprises a stand 41 and a clamping piece 42. The stand 41 is fixed on the adapter platform 31. The clamping piece 42 is fixedly connected with the frame 11, and the clamping piece 42 is used to clamp the stand 41. The clamping piece 42 comprises two clamping pieces. A third fastener 43 is disposed on the clamping piece 42 and penetrates the two clamping pieces, and the third fastener 43 is used to clamp the stand 41 by the clamping piece 42. Optionally, the clamping piece 42 is integrally formed with the frame 11, and the fastening degree is better. The bottom surface of the clamping piece 42 is flush with the bottom surface of the frame 11. In an example, in order to further improve the fastening effect of the stand 41 and the clamping piece 42, a sixth fastener 44 is further disposed on the clamping piece 42, and the sixth fastener 44 directly abuts against the stand 41 after penetrating one clamping piece. The clamping piece is easy to adjust and fix, and convenient to operate.

[0064] In some optional embodiments, the bottom of the stand 41 has an internal thread hole, the adapter platform 31 has a second opening, and the stand 41 is threadedly connected with the second opening through a fourth fastener 45. The head of the fourth fastener 45 is located below the adapter platform 31.

[0065] In some embodiments, the horizontal displacement adjustment part 5 comprises a displacement support 51. The top surface of the displacement support 51 has a second mounting hole 52, and the displacement support 51 and the adapter table 31 are fixed by the second fastener 34. The four corners of the displacement support 51 are provided with straight notches 54, and the straight notches 54 have fifth fasteners 53 for fixing the displacement support 51 and the pitch adjustment part 6. When the fifth fastener 53 is not tightened, the screw part of the fifth fastener 53 can move in the length direction of the straight notch 54, thereby adjusting the placement position of the optical lens 7 on the reference surface. In an example, the bottom surface of the displacement support 51 is rectangular, and the angle between the length direction of the straight notch 54 and the bottom edge of the displacement support 51 is less than 90 degrees. In a preferred example, the angle between the length direction of the straight notch 54 and the bottom edge of the displacement support 51 is equal to 45 degrees. In this way, the translation is more convenient. In an example, in order to avoid the head of the fourth fastener 45 interfering with the displacement support 51, an arc-shaped concave surface 55 is arranged on the side of the displacement support below the fourth fastener 45.

[0066] In some embodiments, the pitch adjustment part 6 is an angular displacement slide, which comprises a base 61, a slide 62, and a hand wheel. The base 61 serves as a support. The slide 62 is arranged on the base 61 and is used to make circular arc motion around the rotation center on the median line of the top surface of the slide 62. The slide 62 has a third mounting hole 64, and the fifth fastener 53 is mounted in the third mounting hole 64. The hand wheel 63 is used to adjust the pitch angle of the slide 62 relative to the base 61, thereby adjusting the pitch angle of the optical lens 7. An arc-shaped scale is arranged on the same side of the base 61 and the slide 62, which can show the current rotation angle of the slide 62 relative to the base 61.

[0067] Based on the above purpose, in combination Figures 1-5 with the above-mentioned first aspect, the second aspect of the embodiment of the present application proposes an adjustment method of an optical lens mounting and adjusting device. The optical lens mounting and adjusting device is the optical lens mounting and adjusting device of the first aspect, and the implementation process of the method is as follows:

[0068] In step S102, the optical lens 7 is mounted on the lens mounting part 1, and the base 61 is placed on the reference surface.

[0069] In this embodiment, the reference surface can be a horizontal surface or a specific mounting surface.

[0070] In step S104, the position of the optical lens 7 on the reference surface is adjusted by the movement cooperation between the fifth fastener 53 and the straight notch 54.

[0071] In the embodiment, when the fifth fastener 53 is not screwed, the displacement support 51 can move along the direction of the straight slot 54 relative to the sliding table 62, and after being adjusted to a proper position, the fifth fastener 53 is screwed to fix the displacement support 51 and the sliding table 62.

[0072] In step S106, the placement angle of the optical lens 7 on the reference surface is adjusted through the rotation cooperation between the second fastener 34 and the circular-arc slot 33.

[0073] In the embodiment, when the second fastener 34 is not screwed, the adapter table 31 can rotate relative to the displacement support 51, and after being adjusted to a proper position, the second fastener 34 is screwed to fix the adapter table 31 and the displacement support 51.

[0074] In step S108, the height of the optical lens 7 is adjusted through the rotation of the adjusting bolt 24, and the column 41 is fixed through the clamping member 42.

[0075] In the embodiment, when the clamping member 42 does not clamp the column 41, the head of the adjusting bolt 24 can be rotated by using a screwdriver, the height of the optical lens 7 is observed through the scale line, and after being adjusted to a proper position, the clamping member 42 is fixed to the column 41.

[0076] In step S110, the pitch angle of the optical lens 7 is adjusted by rotating the hand wheel 63 to change the pitch angle of the sliding table 62 relative to the base 61.

[0077] In the embodiment, the hand wheel 63 is connected with a worm gear, when the hand wheel 63 is rotated in different directions, the sliding table 62 swings in different directions, the pitch angle is observed through the scale line, and after being adjusted to a proper position, the rotation of the hand wheel 63 is stopped.

[0078] It should be noted that after the above steps are executed once, the height and the pitch angle of the optical lens can be fine-adjusted according to the spot state and the photoelectric parameters by repeating steps S108 and S110, so that the spot and the photoelectric parameters meet the use requirements.
