[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application.

Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0034] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 This embodiment provides an optical adjustment device 100, including a frame 110, and an optical element 112 arranged on the frame 110, the frame 110 is provided with a first rotating shaft 114, and a first adjustment hole 115 and a first blind hole 116 located on opposite sides of a second rotating shaft 125, the optical adjustment device 100 also includes a base 120, the base 120 is provided with a first positioning plate 122, the first positioning plate 122 is provided with a first positioning hole 1222, the first rotating shaft 114 is rotatably set in the first positioning hole 1222, and a first adjusting member 117 is provided in the first adjusting hole 115, and a first elastic member 118 is provided in the first blind hole 116, and the first elastic member 118 is respectively abutted against the bottom of the base 120 and the bottom of the first blind hole 116.

[0036] For example, the embodiments of the present application do not impose any specific restrictions on the configuration of the optical element 112. The optical element 112 can be in the form of a convex lens, a self-focusing lens, or a cemented lens to meet actual functional requirements. By disposing the optical element 112 on the frame 110, the optical configuration position relative to the frame 110 is fixed, and the purpose of adjusting the optical element 112 can be achieved by adjusting the spatial position of the frame 110.

[0037] By providing a first rotating shaft 114 on the frame 110, the frame 110 is rotatably connected to the first positioning hole 1222 on the first positioning plate 122 via the first rotating shaft 114, thereby adjusting the spatial position of the frame 110. It should be noted that the first rotating shaft 114 and the first frame 110 can be connected in an integral manner or in a detachable manner. The connection between the first rotating shaft 114 and the first positioning hole 1222 restricts the other dimensions of the frame 110, preventing the frame 110 from arbitrarily shifting its position, thereby ensuring the positioning accuracy of the frame 110.

[0038] The first adjustment hole 115 and the first blind hole 116 provided on opposite sides of the first rotating shaft 114 enable the first adjustment member 117 disposed in the first adjustment hole 115 to abut against the base 120 when adjusting the first adjustment member 117. This allows the frame 110 to rotate about the first positioning hole 1222. During the rotation of the frame 110, the first elastic member 118 disposed in the first blind hole 116 balances the forces on the frame 110, thereby ensuring smooth rotation of the frame 110 and maintaining the adjusted relative position, thereby achieving the purpose of fine-tuning the frame 110.

[0039] The optical adjustment device 100 provided in the embodiment of the present application, by providing a first positioning plate 122 on the base 120 and a first positioning hole 1222 on the positioning plate, can adopt a mechanical fixing method in dimensions with relatively low tolerance requirements, avoiding the use of a complex structure for adjustment. In addition, the frame 110 is rotatably connected to the first positioning hole 1222 of the first positioning plate 122 via the first rotating shaft 114, so that the remaining dimensions are achieved by adjusting the first adjustment member 117 provided at the first adjustment hole 115, and during the adjustment process, the first elastic member 118 provided in the first blind hole 116 is supported against the base 120, so that the force on the frame 110 is balanced, which is conducive to ensuring the stability of the current adjusted state. During the adjustment process of the frame 110, the other dimensions of the frame 110 are restricted, and only the rotational dimension needs to be adjusted. With the above method, the assembly of the optical element 112 becomes simple, and no six-dimensional optical adjustment frame is required, which greatly simplifies the structural form and reduces the adjustment time, thereby facilitating the efficient production of large-scale optical devices.

[0040] like Figure 3 As shown, the frame 110 includes an adjusting portion 111 and a connecting portion 113 connected to each other, the first rotating shaft 114 , the first adjusting hole 115 and the first blind hole 116 are all located on the adjusting portion 111 , and the optical element 112 is located on the connecting portion 113 .

[0041] Specifically, the adjustment portion 111 of the frame 110 is used to adjust the position of the frame 110 to optimize the light beam passing through the optical element 112. The first rotating shaft 114, the first adjustment hole 115, and the second blind hole located on the adjustment portion 111 cooperate to achieve single-dimensional adjustment of the frame 110. As the frame 110 is adjusted, the optical element 112 moves synchronously with the frame 110, achieving the desired adjustment.

[0042] In an optional embodiment of the present application, the connecting portion 113 includes at least one of a rectangular, circular, elliptical, or polygonal shape, so that the connecting portion 113 matches the outer shape of the optical element 112 .

[0043] For example, when the optical element 112 is rectangular, the connecting portion 113 can have a corresponding rectangular profile to better match the optical element 112. Similarly, when the optical element 112 is circular, the connecting portion 113 can also have a corresponding circular profile. This approach helps reduce the material used in the frame 110, making the structure simpler and more lightweight.

[0044] like Figure 4 As shown, when the frame 110 and the first positioning plate 122 rotate relative to each other, in order to ensure the position accuracy of the frame 110, during the adjustment process, the frame 110 and the first positioning plate 122 can be fit together, and the rotation angle of the frame 110 can be adjusted. When the frame 110 is adjusted into place, it can be fixed with glue to ensure that the position of the frame 110 is not disturbed by the outside world, which is conducive to improving stability during use.

[0045] like Figure 5 and Figure 6 As shown, the optical adjustment device 100 also includes a fixed seat 130, on which second positioning plates 132 are arranged at intervals, and the second positioning plates 132 are provided with second positioning holes 134 on the same axis, and the base 120 is also provided with support plates 124 corresponding to the second positioning plates 132 respectively, and the support plates 124 are respectively provided with third positioning holes corresponding to the second positioning holes 134, and the third positioning holes and the second positioning holes 134 are inserted with second rotating shafts 125 to enable the base 120 to rotate relative to the second rotating shaft 125, wherein the extension direction of the first rotating shaft 114 is perpendicular to the extension direction of the second rotating shaft 125.

[0046] Specifically, by providing second positioning plates 132 at intervals on the fixing seat 130, and providing support plates 124 corresponding to the second positioning plates 132 on the base 120, when the support plates 124 and the second positioning plates 132 are in contact, the base 120 can be positioned by the second positioning plates 132. By providing second positioning holes 134 on the second positioning plates 132 on the same axis, and providing third positioning holes corresponding to the second positioning holes 134 on the support plates 124, when the base 120 and the support plates 124 are mounted in correspondence, the third positioning holes correspond to the second positioning holes 134, and the second rotating shaft 125 is inserted into the third positioning hole and the second positioning hole 134, respectively, so that the base 120 rotates about the second rotating shaft 125, thereby achieving the purpose of adjusting the posture of the base 120.

[0047] The extension direction of the first rotating shaft 114 is perpendicular to the extension direction of the second rotating shaft 125, thereby achieving the purpose of adjusting the frame 110 on the base 120 in different dimensions. In addition, the embodiment of the present application does not impose any specific restrictions on the setting form of the third positioning hole, as long as it can form the required matching relationship with the second positioning hole 134. For example, the third positioning hole can be in the form of a through hole or a blind hole. The above form facilitates the positioning and installation between the base 120 and the fixing base 130 and ensures the positioning accuracy in other dimensions.

[0048] It should be noted that the embodiment of the present application does not impose any specific restrictions on the configuration of the base 120, as long as it can play the role of supporting and positioning. For example, the base 120 of the embodiment of the present application can be Figure 1 In the form of the embodiment, the base 120 can be fixed on other fixing parts, or the base 120 itself can be used as a positioning seat. In this case, only one-dimensional adjustment of the frame 110 is required. When the positioning requirements for the optical element 112 are higher, the base 120 of the embodiment of the present application can be used. Figure 5 In this case, the matching form and adjustment form between the base 120 and the frame 110 remain unchanged, and the adjustment of the base 120 is realized to finally realize the two-dimensional adjustment of the frame 110 to meet the use requirements.

[0049] like Figure 5 、 Figure 6 and Figure 7 As shown, a first adjusting block 126 and an oppositely arranged second adjusting block 127 are provided on the base 120, wherein the first adjusting block 126 and the second adjusting block 127 are located on opposite sides of the third positioning hole, a second adjusting hole 1262 is provided on the first adjusting block 126, a second adjusting member is provided in the second adjusting hole 1262, a second blind hole 1271 is provided on the second adjusting block 127, a second elastic member 1272 is provided in the second blind hole 1271, and the second elastic member 1272 is respectively abutted against the bottom of the fixing seat 130 and the second blind hole.

[0050] Specifically, by providing the first adjustment block 126 and the second adjustment block 127 on opposite sides of the third positioning hole, and providing the second adjustment hole 1262 on the first adjustment block 126, and providing the second blind hole 1271 on the second adjustment block 127, when adjusting the second adjustment member disposed in the second adjustment hole 1262, the second adjustment member can be brought into contact with the fixing member, thereby causing the base 120 to rotate about the second rotation axis 125. During the rotation of the frame 110, the second elastic member 1272 disposed in the second blind hole balances the forces on the base 120, thereby ensuring the stability of the base 120 during rotation and maintaining the adjusted relative position, thereby achieving the purpose of adjusting the base 120 to ultimately fine-tune the frame 110.

[0051] like Figure 7 As shown, in an optional embodiment of the present application, the second adjustment hole 1262 and the two second blind holes 1271 are arranged in an isosceles triangle, wherein the line connecting the two second blind holes 1271 forms the base of the isosceles triangle. In this way, when the base 120 is large and has a wide span, the second adjustment member disposed in the second adjustment hole 1262 and the second elastic member 1272 disposed in the second blind hole abut against the fixing base 130, forming a stable triangular support, which helps to improve the stability of the base 120 during adjustment.

[0052] like Figure 6 As shown, the first positioning hole 1222 is located at the symmetrical center of the two second adjustment blocks 127. This is beneficial for centering the frame 110 and facilitating the final adjustment of the frame 110.

[0053] In an optional embodiment of the present application, the first adjustment hole 115 and the second adjustment hole 1262 are threaded holes, and the first adjustment member 117 and the second adjustment member are jackscrews. With this arrangement, when adjusting the frame 110 or the base 120, only the jackscrews need to be turned, resulting in a simpler adjustment method with high adjustment precision, which helps improve adjustment efficiency.

[0054] In an optional embodiment of the present application, the first elastic member 118 and the second elastic member 1272 are either compression springs or rubber columns. When adjusting via a jackscrew, fine-tuning can be achieved by compressing the rubber column or compression spring, ensuring that the state is maintained during fine-tuning, which helps simplify the adjustment method and improve the reliability of the adjustment.

[0055] In an optional embodiment of the present application, the two support plates 124 are respectively fitted with the inner sides of the two second positioning plates 132 , or the two support plates 124 are respectively fitted with the outer sides of the two second positioning plates 132 .

[0056] Specifically, when the two support plates 124 are respectively fitted with the inner sides of the two positioning plates, Figure 5In the form of, when the two support plates 124 are respectively attached to the outer sides of the two second positioning plates 132, the support plate 124 can be along Figure 6 The middle support plate 124 is extended in the reverse direction to form the required leg support, and is moved outward by the thickness of the second positioning plate 132. In actual applications, it can be flexibly set according to needs.

[0057] like Figure 8 As shown, the embodiment of the present application further provides an adjustment method of the optical adjustment device 100, which is applied to the optical adjustment device 100 in the aforementioned embodiment, and the method includes:

[0058] S100 , fixing the optical element 112 to the frame 110 , and rotating the frame 110 to connect to the first positioning hole 1222 via the first rotating shaft 114 , and fitting it to the first positioning plate 122 .

[0059] S200 , rotating the first adjusting member 117 to rotate the frame 110 around the first positioning hole 1222 via the first rotating shaft 114 .

[0060] S300 , when the position of the light spot formed on the optical detection panel by the light beam emitted through the optical element 112 reaches a preset value, stop rotating the first adjusting member 117 and fix the frame 110 to the base 120 .

[0061] Specifically, the above method is suitable for adjusting the optical element 112 in one dimension through the frame 110, and the tolerances in other dimensions can meet the optical requirements. The above method is conducive to simplifying the structural form and reducing the adjustment time, thereby facilitating the efficient production of large-scale optical devices.

[0062] like Figure 9 As shown, in an optional embodiment of the present application, the optical adjustment device 100 further includes a fixing seat 130, a first adjustment block 126 is provided on the base 120, and a second adjustment block 127 is provided opposite thereto, the first adjustment block 126 is provided with a second adjustment hole 1262, a second adjustment member is provided in the second adjustment hole 1262, the second adjustment block 127 is provided with a second blind hole, and a second elastic member 1272 is provided in the second blind hole, the method further includes:

[0063] S100 , fixing the optical element 112 to the frame 110 , and rotating the frame 110 to connect to the first positioning hole 1222 via the first rotating shaft 114 , and fitting it to the first positioning plate 122 .

[0064] S400 , aligning the third positioning hole of the base 120 with the second positioning hole 134 of the fixing base 130 , and inserting the second rotating shaft 125 into the third positioning hole and the second positioning hole 134 .

[0065] S500 , rotating the first adjusting member 117 to rotate the frame 110 around the first positioning hole 1222 via the first rotating shaft 114 , and / or rotating the second adjusting member to rotate the base 120 around the second positioning hole 134 via the second rotating shaft 125 .

[0066] Specifically, when the adjustment requirements for the optical element 112 are higher, the above-mentioned adjustment method can be adopted. During the adjustment process, if rotating only the first adjustment member 117 can meet the required requirements, only the first adjustment member 117 can be rotated. If rotating only the second adjustment member can meet the required requirements, only the second adjustment member can be rotated. If rotating only the first adjustment member 117 or the second adjustment member cannot meet the required requirements, the first adjustment member 117 and the second adjustment member can be rotated simultaneously to adjust the optical element 112. After the adjustment is completed, the frame 110 is fixed to the base 120, and the base 120 is fixed to the fixing base 130. Glue can be used for fixing. The entire operation process is simple and efficient, which helps reduce the adjustment time and thus promotes the efficient production of large quantities of optical devices.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
