Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical equipment, more particularly, to a long lens adjusting device and an optical quantity detection device. BACKGROUND

[0002] In the field of optical equipment, especially in optical quantity detection devices, the fixation and pose adjustment of long lens assemblies are key links in the integration and adjustment of optical systems. However, the existing long lens fixation and pose adjustment schemes have many problems, among which the disadvantages of unilateral locking are particularly prominent.

[0003] In the prior art, the fixation of long lenses is mostly unilateral locking, forming a cantilever beam structure. This structure is prone to bending deformation when under stress, especially when the lens is too heavy or too long. Due to the mechanical properties of the cantilever beam structure, the deformation at the end is large, which causes the lens to shake easily during use. The unilateral locking structure cannot provide sufficient support force and stability, making it difficult to ensure the accuracy and reliability of the lens during adjustment and use. This shaking directly affects the imaging quality and measurement accuracy of the optical system, and may also cause the lens to fall off the fixation device, resulting in equipment damage and measurement failure.

[0004] Therefore, how to solve the problem of insufficient stability caused by the existing unilateral locking method is a problem that needs to be solved by the technical personnel in the field at present. SUMMARY

[0005] The present application discloses a long lens adjusting device to solve the problem of insufficient stability caused by the existing unilateral locking method. Rigid locking components and flexible locking components are arranged on both sides of the adjusting module, and they are matched along the lens axis to achieve bilateral locking. This effectively solves the problem of insufficient stability caused by unilateral locking in the prior art, significantly enhances the fixation stability of the lens after adjustment, avoids shaking or deformation caused by uneven unilateral stress, ensures the stability of the lens during use, and thus improves the imaging quality and measurement accuracy of the optical system.

[0006] In a first aspect, the application provides a medium-long lens adjusting device, comprising: an adjusting module, configured to realize pitch and yaw pose adjustment of the lens; a locking module, configured to fix the lens after the pose adjustment; the locking module comprises a flexible locking component configured to provide flexible support and a rigid locking component configured to provide rigid support, the rigid locking component and the flexible locking component are respectively arranged on two sides of the adjusting module and cooperatively realize double-side locking; and a supporting module, arranged on the adjusting module, configured to support the lens. By arranging the rigid locking component and the flexible locking component on two sides of the adjusting module and cooperatively realizing double-side locking, the problem of insufficient stability caused by single-side locking in the prior art is effectively solved. This double-side locking mode can significantly enhance the fixing stability of the lens after adjustment, avoid shaking or deformation caused by uneven stress on one side, and is particularly suitable for fixing scenarios of medium-heavy or heavy modules, such as a horizontally placed medium-long lens that is too heavy or too long, to ensure the stability of the lens during use, thereby improving the imaging quality and measurement accuracy of the optical system. Further, the rigid locking component provides a solid support basis, while the flexible locking component has a certain elastic deformation capability, which can adapt to processing tolerances and assembly errors, further improving the reliability and stability of locking. This locking mode combining flexibility and rigidity can not only eliminate the influence of processing tolerances on lens fixing, but also to a certain extent, buffer external impact or vibration, protect the lens from damage, and prolong the service life of the lens.

[0007] In a possible implementation, the adjusting module comprises a bottom plate seat and a rotating shaft plate, and the bottom plate seat and the rotating shaft plate are rotationally connected through at least one first rotation guide component. By arranging the first rotation guide component, the rotational connection between the bottom plate seat and the rotating shaft plate can have high-precision rotation guidance, so that the lens can realize accurate angle adjustment during yaw adjustment.

[0008] In a possible implementation, the supporting module comprises a base and a supporting seat arranged on the base, and the supporting seat is provided with a supporting groove for supporting the lens. The design of the supporting groove can provide stable support for the lens, ensuring good pose and position stability of the lens during adjustment and use. The operator can place the lens in the supporting groove, and then adjust the pose through the adjusting module without worrying about the lens falling or being damaged due to lack of support during adjustment. This design simplifies the installation and adjustment process of the lens, improves work efficiency, and reduces operation difficulty and risk.

[0009] In a possible implementation, the support seat is provided with at least two, and the at least two support seats are arranged along the extension direction of the base. By arranging multiple support seats, the support points of the lens on the support module are increased, forming a multi-point support structure, which can significantly improve the stability of the lens, especially when the lens is heavy or long, effectively preventing the lens from shaking or tilting due to unstable center of gravity.

[0010] In a possible implementation, the support groove is provided with an anti-skid pad. The arrangement of the anti-skid pad can significantly enhance the friction between the support groove and the lens, effectively preventing the lens from sliding or rolling in the support groove. This is particularly important for heavy or long optical components such as medium or long lenses, which can ensure the stability of the lens during adjustment and use, avoid displacement or shaking caused by sliding, and thus improve the imaging quality and measurement accuracy of the optical system.

[0011] In a possible implementation, the support module further comprises a flexible pressing block with elasticity, and the flexible pressing block is provided with at least two, and the at least two flexible pressing blocks are detachably arranged on the corresponding support seats to fix the lens. The flexible pressing block has elasticity, which can provide uniform and reliable fixing force for the lens to ensure that the lens remains stable on the support seat, even under vibration or external force, and will not loosen or shift, which can significantly improve the adjustment accuracy of the lens. Moreover, the elastic design of the flexible pressing block can adapt to lenses of different outer diameters, so that even if there is a certain deviation in the machining accuracy of the lens, the flexible pressing block can be adapted through its elastic deformation, thereby achieving stable fixation.

[0012] In a possible implementation, the two sides of the rotation shaft plate are provided with supports, and the supports are rotationally connected with the base through a second rotation guide component. By arranging supports on both sides of the rotation shaft plate and rotationally connecting them with the base through a second rotation guide component, a double-sided support structure is formed, which can significantly enhance the stability of the rotation shaft plate, especially when the rotation shaft plate bears a large load, effectively preventing the rotation shaft plate from shaking or deforming. The second rotation guide component can provide precise rotation guidance, ensuring smooth rotation of the rotation shaft plate during adjustment, reducing adjustment errors caused by unstable rotation, and significantly improving the accuracy and repeatability of adjustment.

[0013] In a possible implementation, the axes of the first rotation guide component and the second rotation guide component are arranged orthogonally in the same plane. The orthogonally arranged rotation guide components can ensure that the pitch and yaw adjustments of the lens are completely independent, and adjusting the pitch angle of the lens will not affect its yaw angle, and adjusting the yaw angle of the lens will not affect its pitch angle. This decoupling design greatly improves the accuracy and efficiency of adjustment.

[0014] In a possible implementation, a limiting structure is arranged between the bottom seat and the rotation shaft plate to limit the rotation angle of the rotation shaft plate, the limiting structure comprises a limiting bolt and a limiting block, the limiting block protrudes from both sides of the rotation shaft plate, the limiting bolt connects the bottom seat and the limiting block, the limiting block is provided with an arc-shaped limiting slot for the movement of the limiting bolt, and the length direction of the limiting slot is consistent with the rotation direction of the rotation shaft plate. The limiting structure can accurately limit the rotation angle of the rotation shaft plate, ensure that the rotation shaft plate does not exceed the predetermined angle range during adjustment, and significantly improve the accuracy and reliability of adjustment by accurately controlling the rotation angle, thereby improving the imaging quality and measurement accuracy of the optical system.

[0015] In a possible implementation, the adjustment module further comprises a plurality of adjustment bolts, at least two of which are arranged at both ends of the base and used to adjust the pitch angle of the lens, and at least two of which are arranged on the same side of the bottom seat through the top screw seat and used to adjust the yaw angle of the lens. By arranging the adjustment bolts at both ends of the base to adjust the pitch angle of the lens and arranging the adjustment bolts on the same side of the bottom seat through the top screw seat to adjust the yaw angle of the lens, the independent adjustment of the two degrees of freedom of the pitch and yaw of the lens can be realized, the accuracy and flexibility of the adjustment are significantly improved, and the position adjustment of the lens in different directions is ensured not to interfere with each other. The design of multiple adjustment bolts can provide more precise adjustment capability, and the operator can adjust the angle of the lens by fine-tuning each adjustment bolt, thereby meeting the needs of high-precision optical systems.

[0016] In a possible implementation, the first rotation guide component and the second rotation guide component are mark pins, and the assembly direction of the mark pin is orthogonal to the adjustment direction of the adjustment bolt. The orthogonal arrangement of the assembly direction of the mark pin and the adjustment direction of the adjustment bolt can ensure that the pitch and yaw adjustment of the lens are completely independent, improve the accuracy and efficiency of the adjustment, and is especially suitable for optical systems with high adjustment accuracy requirements. The orthogonal arrangement of the mark pin and the adjustment bolt can ensure that the lens is accurately aligned during adjustment, and can significantly improve the overall performance of the system.

[0017] In a possible implementation, the rotation shaft plate is provided with a connecting lug at both ends of one side, the connecting lug is located on the same side of the rotation shaft plate as the top screw seat, and the rigid locking component is detachably arranged on the connecting lug. By arranging the connecting lug at both ends of one side of the rotation shaft plate and detachably mounting the rigid locking component on the connecting lug, a double-support structure is formed, which can significantly enhance the stability of the rotation shaft plate, especially when the rotation shaft plate bears a large load, effectively preventing the rotation shaft plate from shaking or deforming, so that the load of the rotation shaft plate can be evenly distributed on the two connecting lugs, further improving the stability and reliability of the structure.

[0018] In a possible implementation, the same side of the rotation shaft plate and the base is provided with a mounting boss for mounting the flexible locking component. The mounting boss provides an accurate mounting position for the flexible locking component, ensuring that the flexible locking component can be accurately mounted at the predetermined position, significantly improving the fixing effect of the flexible locking component and ensuring that it will not loosen or shift during use.

[0019] In a possible implementation, the flexible locking component is a flexible locking sheet with elasticity, which is provided with a first connecting hole and a second connecting hole. The first connecting hole is a round hole, the second connecting hole is a U-shaped hole, and the second connecting hole is in communication with one side edge of the flexible locking sheet. The outer periphery of the first connecting hole is provided with an inverted U-shaped slot. The first connecting hole is connected with the mounting boss on the rotation shaft plate, and the second connecting hole is connected with the mounting boss on the base, providing sufficient space for the pitch adjustment of the base. When adjusting the pitch angle of the lens, the design of the U-shaped hole will not limit the movement of the base, thereby ensuring the smoothness and flexibility of the adjustment process. The inverted U-shaped slot design of the outer periphery of the first connecting hole further enhances the elastic deformation ability of the flexible locking sheet, making it better adapt to lenses of different sizes and improving the fixing effect. The elastic design of the flexible locking sheet can absorb part of the vibration, reducing the shaking of the lens during use due to vibration, thereby improving the imaging quality and measurement accuracy of the optical system.

[0020] In a possible implementation, one of the flexible locking sheets is provided with two first connecting holes, a second connecting hole and a slot. By providing two first connecting holes and two second connecting holes, the flexible locking sheet can be connected with the base and the rotation shaft plate through two fixing points. This double-point fixing method can significantly enhance the fixing force of the flexible locking sheet, ensuring that it will not loosen or shift during use, thereby improving the stability of the entire adjustment device.

[0021] In a second aspect, the present application provides an optical quantity detection device, which comprises the adjustment device of the medium-long lens as described in any one of the above aspects, and a medium-long lens used in cooperation with the device. The adjustment device of the medium-long lens can realize high-precision pitch and yaw adjustment, ensuring accurate alignment of the lens at different angles, significantly improving the imaging quality and measurement accuracy of the optical system, and making it better meet the needs of high-precision optical detection.

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative work under the premise of the present application are within the scope of protection of the present application.

[0042] In the present application, unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting”, “fixing” and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0043] The present application provides an adjusting device for a medium-long lens, which is used to solve the problem of insufficient stability caused by the existing unilateral locking mode. The rigid locking component 22 and the flexible locking component 21 are respectively arranged on both sides of the adjusting module 1, and are cooperated to realize bilateral locking, effectively solving the problem of insufficient stability caused by unilateral locking in the prior art. The fixing stability of the lens 8 after adjustment can be significantly enhanced, the shaking or deformation caused by uneven unilateral stress can be avoided, the lens 8 can be ensured to remain stable during use, and thus the imaging quality of the optical system and the measurement accuracy are improved.

[0044] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The application discloses a medium-long lens adjusting device, which comprises an adjusting module 1, a locking module 2 and a supporting module 3. The adjusting module 1 is used for realizing pitch and yaw pose adjustment of a lens 8. The locking module 2 is used for fixing the lens 8 after the pose adjustment. The locking module 2 comprises flexible locking components 21 for providing flexible support and rigid locking components 22 for providing rigid support. The rigid locking components 22 and the flexible locking components 21 are respectively arranged on two sides of the adjusting module 1 and are cooperatively used for realizing double-side locking. The supporting module 3 is arranged on the adjusting module 1 and is used for supporting the lens 8. By arranging the rigid locking components 22 and the flexible locking components 21 on two sides of the adjusting module 1 and cooperatively realizing double-side locking, the problem of insufficient stability caused by single-side locking in the prior art is effectively solved. The double-side locking mode can significantly enhance the fixing stability of the lens 8 after the adjustment, avoids shaking or deformation caused by uneven stress on a single side, and is particularly suitable for fixing scenes of medium-heavy load or heavy load modules, such as a horizontally arranged medium-long lens 8 which is too heavy or too long, so that the lens 8 can be kept stable during use, thereby improving the imaging quality and the measurement accuracy of an optical system. Further, the rigid locking components 22 provide a solid support basis, and the flexible locking components 21 have a certain elastic deformation capacity, so as to adapt to machining tolerances and assembly errors, and further improve the reliability and stability of locking. The locking mode combining flexibility and rigidity can not only eliminate the influence of machining tolerances on fixing of the lens 8, but also buffers external impact or vibration to a certain extent, protects the lens 8 from damage, and prolongs the service life of the lens 8.

[0045] Please refer to Figure 1 、 Figure 5 and Figure 6 The adjusting module 1 comprises a bottom plate seat 11 and a rotating shaft plate 12, and the bottom plate seat 11 and the rotating shaft plate 12 are rotationally connected through at least one first rotation guide component 4. By arranging the first rotation guide component 4, the rotation connection between the bottom plate seat 11 and the rotating shaft plate 12 can have high-precision rotation guide, so that the lens 8 can realize accurate angle adjustment during yaw adjustment.

[0046] Exemplarily, the adjustment module 1 is mainly composed of a bottom seat 11 and a rotating shaft plate 12. The bottom seat 11 serves as the basic structural component of the adjustment module 1, and is used for mounting and fixing other related components. The bottom seat 11 has a rectangular plate structure as a whole, and the rotating shaft plate 12 has a shape matching with the bottom seat 11 and can be stably connected with the bottom seat 11. In order to realize the rotating connection between the bottom seat 11 and the rotating shaft plate 12, a first rotating guide component 4 is arranged between the bottom seat 11 and the rotating shaft plate 12 in the embodiment. The center positions of the bottom seat 11 and the rotating shaft plate 12 are provided with a circular through hole for mounting the first rotating guide component 4. The first rotating guide component 4 is a marking pin, which has a cylindrical shape and has a flat head and a threaded rod portion. The head of the marking pin is flat, which helps to provide a stable contact surface during installation, so as to ensure that the marking pin can be fixed firmly in the pin hole of the rotating shaft plate 12. The rod portion of the marking pin has external threads, which enables it to be fixed to the bottom seat 11 by threaded connection, so as to ensure that the marking pin will not loosen during the rotation of the rotating shaft plate 12. Moreover, the marking pin can ensure that the relative movement between components is accurate and repeatable, which is particularly important for optical systems that require high-precision positioning.

[0047] In actual application, the first rotating guide component 4 can also be replaced by a high-precision bearing structure, specifically a deep groove ball bearing. The deep groove ball bearing has the advantages of small friction coefficient, high limit speed, simple structure, easy installation and maintenance, etc., and can provide accurate guidance and support for the relative rotation between the bottom seat 11 and the rotating shaft plate 12. During installation, the inner ring of the deep groove ball bearing is fixedly connected with the rotating shaft plate 12 by interference fit, and the outer ring is installed with the bottom seat 11 by transition fit. Through this connection mode, the rotating shaft plate 12 can flexibly rotate relative to the bottom seat 11 around the axis of the deep groove ball bearing, so as to realize the yaw position adjustment of the lens 8. During the adjustment process, the operator can manually rotate the rotating shaft plate 12 to adjust the yaw angle of the lens 8 in the horizontal direction, so as to meet the optical detection requirements in different scenes.

[0048] Among them, the bottom seat 11 and the rotating shaft plate 12 can be made of high-strength aluminum alloy material to ensure sufficient mechanical strength and light weight, facilitating the installation and operation of the entire device. The four corners of the bottom seat 11 are provided with connecting tables, and corresponding threaded connection holes are arranged on the connecting tables, so that the bottom seat 11 can be fixed on the operation platform by screws.

[0049] Please refer to Figure 1 , Figure 5 and Figure 6In order to improve the accuracy and stability of the adjustment, the bottom plate base 11 and the rotating shaft plate 12 are provided with a limiting structure 6 for limiting the rotating angle of the rotating shaft plate 12, the limiting structure 6 includes a limiting bolt 61 and a limiting block 62, the limiting block 62 protrudes from both sides of the rotating shaft plate 12, the limiting bolt 61 connects the bottom plate base 11 and the limiting block 62, the limiting block 62 is provided with an arc-shaped limiting slot 63 for the movement of the limiting bolt 61, and the length direction of the limiting slot 63 is consistent with the rotating direction of the rotating shaft plate 12. The limiting structure 6 can accurately limit the rotating angle of the rotating shaft plate 12, ensure that the rotating shaft plate 12 will not exceed the predetermined angle range during the adjustment process, and through the accurate control of the rotating angle, the accuracy and reliability of the adjustment can be significantly improved, and then the imaging quality and the measurement accuracy of the optical system are improved.

[0050] For example, the limiting block 62 is a rectangular metal block made of high-strength stainless steel material, which has good mechanical properties and wear resistance. The limiting block 62 and the rotating shaft plate 12 are an integral structure, and the limiting block 62 protrudes from the edge position of the rotating shaft plate 12. The length of the limiting block 62 is adapted according to the size of the rotating shaft plate 12 to ensure that it can effectively limit the rotating angle of the rotating shaft plate 12. An arc-shaped limiting slot 63 is arranged on the limiting block 62, and the length direction of the limiting slot 63 is consistent with the rotating direction of the rotating shaft plate 12. The radius of the limiting slot 63 is designed according to the rotating radius of the rotating shaft plate 12 to ensure that the limiting bolt 61 can smoothly slide in the slot while limiting its movement within the predetermined angle range. The limiting bolt 61 is a standard M6 bolt, one end of which is connected to the bottom plate base 11 through a thread, and the other end is in contact with the limiting block 62 through the limiting slot 63. By adjusting the position of the limiting bolt 61 in the limiting slot 63, the rotating angle of the rotating shaft plate 12 can be accurately limited. The head of the limiting bolt 61 is hexagonal, which is convenient for adjusting with a wrench. Moreover, the end face of the limiting block 62 close to the bottom plate base 11 protrudes from the end face of the rotating shaft plate 12, and at the same time, the two sides of the bottom plate base 11 are provided with connecting blocks 111 protruding from the edge position of the bottom plate base 11, the connecting blocks 111 and the bottom plate base 11 are an integral structure, the connecting blocks 111 are provided with threaded holes for connecting the limiting bolt 61, and the end face of the connecting blocks 111 close to the limiting block 62 protrudes from the end face of the bottom plate base 11. In this way, the contact area between the bottom plate base 11 and the rotating shaft plate 12 is reduced, thereby reducing the friction when the rotating shaft plate 12 rotates relative to the bottom plate base 11, and ensuring the rotating connection between the bottom plate base 11 and the rotating shaft plate 12.

[0051] Please refer to Figure 4 and Figure 7The support module 3 includes a base 31 and support seats 32 provided on the base 31, and the support seats 32 are provided with support grooves 321 for supporting the lens 8. The support seats 32 are at least two, and the at least two support seats 32 are arranged along the extension direction of the base 31. The design of the support grooves 321 can provide stable support for the lens 8, ensuring that the lens 8 maintains good posture and position stability during adjustment and use. The operator can place the lens 8 in the support groove 321, and then adjust the position through the adjustment module 1, without worrying that the lens 8 will fall or be damaged during adjustment due to lack of support. This design simplifies the installation and adjustment process of the lens 8, improves work efficiency, and reduces operation difficulty and risk. By providing multiple support seats 32, the support points of the lens 8 on the support module 3 increase, forming a multi-point support structure, which can significantly improve the stability of the lens 8, especially when the lens 8 is heavy or long, effectively preventing the lens 8 from shaking or tilting due to unstable center of gravity.

[0052] For example, the base 31 is the foundation of the support module 3, the shape of the base 31 is rectangular, and the middle part of the base 31 is provided with a rectangular hole to provide installation and rotation space for the first rotary guide part 4. Specifically, the rectangular hole can extend along the extension direction of the base 31, and the base 31 is provided with two support seats 32, which are arranged along the extension direction of the base 31 and symmetrically distributed on both sides of the rectangular hole, which helps to evenly distribute the weight of the lens 8 and reduce the eccentric pressure on the base 31, thereby improving the stability of the entire support module 3. In order to facilitate the installation and positioning of the lens 8, support grooves 321 are provided on the support seats 32 for direct contact with the lens 8 and provide support to provide stable support. The size of the support groove 321 can be designed according to the shape and size of the lens 8, as long as it can ensure the stable positioning of the lens 8 in the groove. The base 31 and the support seat 32 are integrally machined to improve the structural strength of the entire support module 3 and ensure the size and position accuracy between the base 31 and the support seat 32, which is crucial for the precise alignment of optical equipment. High-precision machining can reduce errors during assembly and improve the imaging quality and measurement accuracy of the optical system.

[0053] In a feasible implementation, the support groove 321 is a V-shaped groove, which can self-position the lens 8 and automatically guide the lens 8 to the correct position, ensuring the correct alignment of the lens 8 in the groove, and can provide better stability than a flat support groove 321, as it can hold the lens 8 more firmly, reducing movement and vibration of the lens 8 in the groove, and can also accommodate lenses 8 of different sizes, increasing the versatility of the support module 3. In addition, the inclined surface design of the V-shaped groove can reduce friction between the lens 8 and the support groove 321, making it easier for the lens 8 to move in the groove, facilitating adjustment and positioning, and also reducing wear on the contact surface between the lens 8 and the support groove 321, thereby improving the durability of the entire support module 3.

[0054] In one possible implementation, the support groove 321 is provided with anti-slip pads. The provision of anti-slip pads can significantly enhance the friction between the support groove 321 and the lens 8, effectively preventing the lens 8 from sliding or rolling within the support groove 321. This is particularly important for heavier or longer optical components such as medium or long lenses 8, as it can ensure the stability of the lens 8 during adjustment and use, avoiding displacement or shaking caused by sliding, thereby improving the imaging quality and measurement accuracy of the optical system.

[0055] Further, the two side walls of the V-shaped groove can be covered with anti-slip pads to further increase friction and protect the surface of the lens 8 from scratching. For example, anti-slip pads are attached to the inner walls of the V-shaped groove, evenly distributed along the inner walls of the V-shaped groove, covering all areas that the lens 8 may contact, to ensure that when the lens 8 is placed in the support groove 321, the anti-slip pads can contact the bottom or side of the lens 8, providing maximum friction. The shape of the anti-slip pads is designed to match the shape of the inner walls of the V-shaped groove, which is usually V-shaped or trapezoidal, to make full use of the space of the groove and provide maximum contact area. The edges of the anti-slip pads can be designed with rounded corners to reduce wear on the surface of the lens 8. In actual application, one or more anti-slip pads can be provided in the V-shaped groove according to the size of the V-shaped groove and the size of the lens 8 to be supported. For larger V-shaped grooves, multiple anti-slip pads may be needed to ensure that the entire contact area provides sufficient friction. The number and distribution of anti-slip pads are determined according to actual conditions to achieve the best anti-slip effect. Anti-slip pads are usually made of materials with high friction coefficients, such as rubber, silicone or Teflon (polytetrafluoroethylene) coating. These materials not only provide good anti-slip performance, but also protect the surface of the lens 8 from scratching.

[0056] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the support module 3 further comprises flexible pressing blocks 33 with elasticity, and at least two flexible pressing blocks 33 are detachably arranged in the corresponding support seats 32 to fix the lens 8. The flexible pressing blocks 33 have elasticity and can provide uniform and reliable fixing force for the lens 8 to ensure that the lens 8 remains stable on the support seat 32, even under vibration or external force, and will not loosen or shift, which can significantly improve the adjustment accuracy of the lens 8. Moreover, the elastic design of the flexible pressing blocks 33 allows them to adapt to lenses 8 of different outer diameters, so that even if there is a certain deviation in the machining accuracy of the lens 8, the flexible pressing blocks 33 can adapt through their own elastic deformation, thereby achieving stable fixation.

[0057] In order to further improve the fixing stability of the lens 8, the support module 3 can further include a flexible pressing block 33. The flexible pressing block 33 is elastic and can uniformly press on the outer diameter of the lens 8, ensuring that the lens 8 remains stable on the support seat 32. The design of the flexible pressing block 33 allows it to adapt to lenses 8 of different outer diameters, so that even if there is a certain deviation in the machining accuracy of the lens 8, the flexible pressing block 33 can still adapt through its own elastic deformation, thereby achieving stable fixation.

[0058] For example, the flexible pressing block 33 is of L-shaped structure, which can adapt to lenses 8 of different sizes, increasing the versatility and flexibility of the support module 3. One end of the flexible pressing block 33 is provided with a connecting part, one side of the support seat 32 is provided with a stepped part, and threaded connection holes are arranged on the connecting part and the stepped part. The flexible pressing block 33 is fixed to the support seat 32 by bolts, so that the installation and removal process of the flexible pressing block 33 is simple and fast, facilitating quick replacement or adjustment of the lens 8. The inner side of the flexible pressing block 33 is provided with an arc-shaped groove to reduce the direct pressure on the lens 8, protect the lens 8 from damage, and prolong the service life of the lens 8. The flexible pressing block 33 is made of elastic material and can adapt to lenses 8 of different sizes and shapes, providing a flexible fixing solution and increasing the compatibility of the support system. It has good shock absorption performance and can absorb external vibrations and impacts to protect the lens 8 from damage and improve the stability of the optical system. It can also reduce the hard pressure on the lens 8 to avoid scratching or wearing the surface of the lens 8, thereby prolonging the service life of the lens 8.

[0059] For example, the flexible pressing block 33 is a pressure plate of inverted U-shaped structure, which can adapt to lenses 8 of different sizes, increasing the versatility and flexibility of the support module 3. The two ends of the pressure plate are provided with connecting plates, and the two sides of the support seat 32 are provided with corresponding extension parts. Threaded connection holes are arranged on the connecting plates and the extension parts. The pressure plate is fixed to the support seat 32 by bolts, so that the installation and removal process of the pressure plate is simple and fast, facilitating quick replacement or adjustment of the lens 8. The pressure plate is a sheet metal part and can serve as an elastic deformation amount to press the lens 8.

[0060] In either case, whether the flexible pressing block 33 is of L-shaped structure or the pressure plate is of inverted U-shaped structure, in combination with the V-shaped groove, the lens 8 and the flexible pressing block 33 and the support seat 32 form a three-point support, which can achieve precise axial positioning of the lens 8 and help improve the imaging accuracy and measurement accuracy of the optical equipment.

[0061] For reference Figure 4 and Figure 6The two sides of the rotating shaft plate 12 are provided with supports 121, which are rotationally connected to the base 31 through the second rotation guide component 5. By providing supports 121 on both sides of the rotating shaft plate 12 and rotationally connecting them to the base 31 through the second rotation guide component 5, a double-sided support structure is formed, which can significantly enhance the stability of the rotating shaft plate 12, especially when the rotating shaft plate 12 bears a large load, effectively preventing the rotating shaft plate 12 from shaking or deforming. The second rotation guide component 5 can provide precise rotation guidance, ensuring that the rotating shaft plate 12 rotates smoothly during adjustment, reducing adjustment errors caused by unstable rotation, and significantly improving the accuracy and repeatability of adjustment.

[0062] For example, the base 31 is the foundation of the support module 3, and the base 31 is in the shape of a rectangular plate. The shape of the base 31 matches the rotating shaft plate 12 and can be stably connected to the rotating shaft plate 12. The middle of the base 31 is provided with a rectangular hole extending along the extension direction of the base 31, so that the two sides of the base 31 have a support base for installing the second rotation guide component 5. The two sides of the rotating shaft plate 12 are respectively provided with supports 121, which are located between the two limiting blocks 62 on one side of the rotating shaft plate 12 and are perpendicular to the plate surface of the rotating shaft plate 12. The second rotation guide component 5 is a marker pin, which is in the shape of a cylinder and has a flat head and a threaded rod. The head of the marker pin is flat, which helps to provide a stable contact surface during installation, ensuring that the marker pin can be firmly fixed in the pin hole of the support 121. The rod of the marker pin has external threads, which allows it to be fixed to the base 31 through threaded connection, ensuring that the marker pin does not loosen during rotation of the base 31. Moreover, the marker pin can ensure that the relative movement between components is precise and repeatable, which is particularly important for optical systems that require high-precision positioning.

[0063] In actual application, the second rotation guide component 5 can also be replaced by a high-precision bearing structure, specifically a deep groove ball bearing. The deep groove ball bearing has the advantages of small friction coefficient, high limit speed, simple structure, easy installation and maintenance, etc., and can provide precise guidance and support for the relative rotation between the base 31 and the rotating shaft plate 12. During installation, the inner ring of the deep groove ball bearing is fixedly connected to the base 31 through interference fit, and the outer ring is installed with the rotating shaft plate 12 through transition fit. Through this connection method, the base 31 can rotate flexibly relative to the rotating shaft plate 12 around the axis of the deep groove ball bearing, thereby realizing the tilt adjustment of the lens 8. During adjustment, the operator can rotate the base 31 manually to adjust the tilt angle of the lens 8 in the horizontal direction to meet the optical detection needs in different scenes.

[0064] The base 31 and the support 121 are integrally machined and formed, which improves the structural strength of the entire support module 3, ensures the size and position accuracy between the base 31 and the support 121, and is crucial for the accurate alignment of the optical equipment. High-precision machining can reduce errors in the assembly process and improve the imaging quality and measurement accuracy of the optical system.

[0065] Please refer to Figure 1 、 Figure 2 and Figure 3 , the adjustment module 1 further comprises a plurality of adjustment bolts 13, at least two adjustment bolts 13 are arranged at both ends of the base 31 and used to adjust the pitch angle of the lens 8, and at least two adjustment bolts 13 are arranged on the same side of the bottom plate seat 11 through the top screw seat 14 and used to adjust the yaw angle of the lens 8. By arranging the adjustment bolts 13 at both ends of the base 31 for adjusting the pitch angle of the lens 8, and arranging the adjustment bolts 13 on the same side of the bottom plate seat 11 through the top screw seat 14 for adjusting the yaw angle of the lens 8, the independent adjustment of the two degrees of freedom of the pitch and yaw of the lens 8 can be realized, which significantly improves the adjustment accuracy and flexibility and ensures that the pose adjustment of the lens 8 in different directions does not interfere with each other. The design of multiple adjustment bolts 13 can provide more precise adjustment capability, and the operator can adjust the angle of the lens 8 accurately by fine-tuning each adjustment bolt 13, thereby meeting the needs of high-precision optical systems.

[0066] For example, two adjustment bolts 13 are arranged at both ends of the base 31 and distributed on the outside of the support seat 32, the base 31 is provided with threaded holes, the adjustment bolts 13 are connected with the base 31 through the threaded holes, the end of the adjustment bolt 13 abuts against the upper end face of the rotation shaft plate 12, and by rotating the two adjustment bolts 13, the lifting height of both ends is adjusted, thereby adjusting the pitch angle of the base 31 and changing the pitch angle of the lens 8. The two adjustment bolts 13 are arranged on one side of the rotation shaft plate 12 through two top screw seats 14, the top screw seat 14 is located on both sides of the limiting block 62, the top screw seat 14 is of L-shaped structure, the horizontal plate of the top screw seat 14 is fixed to the bottom plate seat 11 through a screw, the vertical plate of the top screw seat 14 is provided with a threaded hole for mounting the adjustment bolt 13, the end of the adjustment bolt 13 abuts against the rotation shaft plate 12, and by rotating the two adjustment bolts 13, the yaw angle of the rotation shaft plate 12 is adjusted, thereby changing the yaw angle of the lens 8.

[0067] In a possible implementation, the extension line of the axis of the first rotation guiding component 4 and the second rotation guiding component 5 is arranged orthogonally in the same plane. The orthogonally arranged rotation guiding components can ensure that the pitch and yaw adjustment of the lens 8 is completely independent, and the pitch angle of the lens 8 will not be affected when the pitch angle of the lens 8 is adjusted, and the yaw angle of the lens 8 will not be affected when the yaw angle of the lens 8 is adjusted, which improves the accuracy and efficiency of the adjustment. Further, the first rotation guiding component 4 and the second rotation guiding component 5 are mark pins, the assembly direction of the mark pins is arranged orthogonally to the adjustment direction of the adjustment bolt 13, which can ensure that the pitch and yaw adjustment of the lens 8 is completely independent, improves the accuracy and efficiency of the adjustment, can ensure that the lens 8 remains accurately aligned during adjustment, and can significantly improve the overall performance of the system, and is particularly suitable for optical systems with high adjustment accuracy requirements.

[0068] Please refer to Figure 3 and Figure 6 One side of the rotation plate 12 is provided with a connecting lug 122 at both ends, the connecting lug 122 is located on the same side of the rotation plate 12 as the top screw seat 14, and the rigid locking component 22 is detachably arranged on the connecting lug 122. By arranging the connecting lug 122 at both ends of one side of the rotation plate 12, and detachably mounting the rigid locking component 22 on the connecting lug 122, a double support structure is formed, which can significantly enhance the stability of the rotation plate 12, especially when the rotation plate 12 bears a large load, which can effectively prevent the rotation plate 12 from shaking or deforming, so that the load of the rotation plate 12 can be evenly distributed on the two connecting lugs 122, further improving the stability and reliability of the structure.

[0069] For example, the connecting lug 122 is arranged perpendicular to the plate surface of the rotation plate 12, the connecting lug 122 is provided with a U-shaped sliding groove with an upward opening, the rigid locking component 22 is movably arranged in the U-shaped sliding groove, and the end of the rigid locking component 22 is connected to the base 31. When the pitch angle of the base 31 is adjusted, the rigid locking component 22 can slide along the U-shaped sliding groove, thereby ensuring the pitch adjustment of the base 31.

[0070] In this embodiment, the rigid locking component 22 is a locking bolt, and the base 31 is provided with a threaded hole matched with the locking bolt.

[0071] Please refer to Figure 6 and Figure 7 The same side of the rotation plate 12 and the base 31 is provided with a mounting boss 7 for mounting the flexible locking component 21. The mounting boss 7 provides a precise mounting position for the flexible locking component 21, ensuring that the flexible locking component 21 can be accurately mounted at the predetermined position, and can significantly improve the fixing effect of the flexible locking component 21, ensuring that it will not loosen or shift during use.

[0072] Exemplarily, the flexible locking component 21 and the rigid locking component 22 are respectively located on both sides of the rotating shaft plate 12, the mounting boss 7 protrudes from one side edge of the rotating shaft plate 12 and the base 31, and the two are aligned to ensure the consistency of the installation of the flexible locking component 21. The rotating shaft plate 12 and the base 31 are each provided with two mounting bosses 7, and the mounting bosses 7 are located on both sides of the limiting block 62.

[0073] Please refer to Figure 1 , Figure 8 and Figure 9 , the flexible locking component 21 is a flexible locking sheet with elasticity, the flexible locking sheet is provided with a first connecting hole 211 and a second connecting hole 212, the first connecting hole 211 is a round hole, the second connecting hole 212 is a U-shaped hole, and the second connecting hole 212 is in communication with one side edge of the flexible locking sheet, and the outer periphery of the first connecting hole 211 is provided with a reverse U-shaped slit 213. The mounting boss 7 of the rotating shaft plate 12 and the base 31 is provided with a threaded connecting hole, and corresponds to the first connecting hole 211 and the second connecting hole 212 on the flexible locking sheet. The first connecting hole 211 is connected with the mounting boss 7 on the rotating shaft plate 12, and the second connecting hole 212 is connected with the mounting boss 7 on the base 31, which provides sufficient space for the pitch adjustment of the base 31. When adjusting the pitch angle of the lens 8, the design of the U-shaped hole will not limit the movement of the base 31, thereby ensuring the smoothness and flexibility of the adjustment process. The reverse U-shaped slit 213 design of the outer periphery of the first connecting hole 211 further enhances the elastic deformation ability of the flexible locking sheet, so that it can better adapt to lenses 8 of different sizes, improve the fixing effect, not only improve the adaptability of the flexible locking sheet, but also further enhance its fixing ability. The elastic design of the flexible locking sheet can absorb part of the vibration, reduce the shaking of the lens 8 in the use process due to vibration, thereby improving the imaging quality and measurement accuracy of the optical system.

[0074] Among them, the flexible locking sheet can be made of spring steel, stainless steel, polyformaldehyde, nylon, polyurethane, silica gel and the like.

[0075] In one possible implementation, a flexible locking sheet is provided with two first connecting holes 211, two second connecting holes 212 and two slits 213. By providing two first connecting holes 211 and two second connecting holes 212, the flexible locking sheet can be connected with the base 31 and the rotating shaft plate 12 through two fixing points. This double-point fixing method can significantly enhance the fixing force of the flexible locking sheet, ensure that it will not loosen or shift during use, thereby improving the stability of the entire adjustment device.

[0076] Exemplary, the central axis of the first connecting hole 211, the second connecting hole 212 and the slot 213 is the same line. During installation, the flexible locking sheet is placed between the rotating shaft plate 12 and the base 31, ensuring that the two first connecting holes 211 are aligned with the mounting bosses 7 on the rotating shaft plate 12, and the two second connecting holes 212 are aligned with the mounting bosses 7 on the base 31. Through the first connecting hole 211 and the second connecting hole 212, the flexible locking sheet is fixed on the rotating shaft plate 12 and the base 31 by using bolts or other fasteners. The tightening degree of the bolts is adjusted to ensure that the flexible locking sheet can adapt to lenses 8 of different sizes and provide stable fixing force.

[0077] The installation process of the adjusting device is as follows: the bottom base 11 and the rotating shaft plate 12 are assembled together from top to bottom by a mark pin, and then the rotating shaft plate 12 and the base 31 are assembled together from the side by two mark pins. The bottom base 11 has two top screw seats 14 on one side, and the adjusting bolts 13 on the top screw seats 14 are used to adjust the yaw of the rotating shaft plate 12 (adjustment is made by adjusting the length of the adjusting bolts 13). The base 31 has adjusting bolts 13 at both ends from top to bottom, which are used to adjust the pitch of the base 31 (adjustment is made by adjusting the length of the adjusting bolts 13). The assembly directions of the two groups of mark pins are orthogonal and layered, and the adjustment direction of the adjusting bolts 13 is orthogonal to the assembly direction of the mark pins, achieving decoupling of the two degrees of freedom of pitch and yaw adjustment. At the same time, the mark pin connecting the bottom base 11 and the rotating shaft plate 12 serves as a rotating shaft and is guided. Because of the high-precision fit between the mark pin and the pin hole, the height of the lens 8 will not be affected during the adjustment process, precise decoupling can be achieved, and the adjustment is convenient and fast. The rotating shaft plate 12 is fixed and locked by two flexible locking sheets on one side of the rotating shaft plate 12 after the pose adjustment of the rotating shaft plate 12 and the base 31 is completed. The other side of the rotating shaft plate 12 is directly locked by the base 31 against the rotating shaft plate 12 with locking bolts. Through this "flexible + rigid" double-sided locking support, the influence of machining tolerance can be eliminated, and the overall structure is more stable.

[0078] When using the above adjusting device to adjust the lens 8, first install the lens 8 in the V-shaped groove of the support block, and the V-shaped groove supports and limits the lens 8. Then install the flexible pressing block 33 on the support seat 32 to limit and fix the lens 8, so as to stabilize the position of the lens 8. The support module 3 adopts a double-V groove structure, and is composed of two flexible pressing blocks 33. The lens 8, the flexible pressing block 33 and the support seat 32 form a three-point support, which can realize precise axial positioning of the lens 8, and is convenient to install. Moreover, because of the design of the flexible pressing block 33, there is a certain deformation allowance, so the lens 8 can be adapted regardless of the design size of the outer diameter tolerance, which can effectively reduce the optical and mechanical processing cost of the lens 8. Then, the pitch and yaw angles of the lens 8 can be adjusted as needed.

[0079] When it is necessary to adjust the tilt angle of lens 8, specifically, starting from the initial position (lens 8 is in a horizontal state, with an adjustment gap between base 31 and rotating plate 12), by rotating the adjusting bolt 13 at the first end of base 31, the first end of base 31 is raised. Base 31 rotates relative to rotating plate 12 via the second rotating guide component 5, causing the second end of base 31 to move down, thereby raising the first end of lens 8 and lowering the second end of lens 8, thus changing the tilt angle of lens 8. The lens tilt angle is controlled by adjusting the extension length of adjusting bolt 13. 8. The angle of elevation; starting from the initial position (lens 8 is in a horizontal state, and there is an adjustment gap between the base 31 and the rotating plate 12), by rotating the adjusting bolt 13 at the second end of the base 31, the second end of the base 31 is lifted. The base 31 rotates relative to the rotating plate 12 through the second rotating guide component 5, causing the first end of the base 31 to move down, thereby lifting the second end of the lens 8 and causing the first end of the lens 8 to move down, thus changing the depression angle of the lens 8. The angle of depression of the lens 8 is controlled by controlling the extension length of the adjusting bolt 13; starting from the initial position ( With the lens 8 in a horizontal position (and an adjustment gap between the base 31 and the rotating plate 12), firstly, by rotating the adjusting bolt 13 at the first end of the base 31, the first end of the base 31 is raised. The base 31 then rotates relative to the rotating plate 12 via the second rotating guide component 5, causing the second end of the base 31 to move downwards. This, in turn, raises the first end of the lens 8 and lowers the second end of the lens 8, thereby changing the elevation angle of the lens 8. The elevation angle of the lens 8 is controlled by adjusting the extension length of the adjusting bolt 13. Then, by rotating the adjusting bolt 13 at the second end of the base 31, the elevation angle of the lens 8 is further adjusted. It drives the second end of the base 31 to rise. The base 31 rotates relative to the rotating shaft plate 12 through the second rotating guide component 5, causing the first end of the base 31 to move down, thereby driving the second end of the lens 8 to rise, causing the first end of the lens 8 to move down, thereby changing the elevation angle of the lens 8, until the length of the adjusting bolt 13 at the second end of the base 31 is longer than the length of the adjusting bolt 13 at the first end of the base 31, and the elevation angle of the lens 8 begins to change to a depression angle. Furthermore, by controlling the length of the adjusting bolt 13 at the second end of the base 31, the angle of depression of the lens 8 is controlled.From the initial position (lens 8 is in the horizontal state, the adjusting gap is left between base 31 and rotating shaft plate 12), first, by rotating adjusting bolt 13 of the second end of base 31, the second end of base 31 is lifted, base 31 rotates relative to rotating shaft plate 12 through second rotating guide part 5, the first end of base 31 is lowered, thereby the second end of lens 8 is lifted, the first end of lens 8 is lowered, the pitch angle of lens 8 is changed, by controlling the length of adjusting bolt 13, the angle of the pitch angle of lens 8 is controlled, then, by rotating adjusting bolt 13 of the first end of base 31, the first end of base 31 is lifted, base 31 rotates relative to rotating shaft plate 12 through second rotating guide part 5, the second end of base 31 is lowered, thereby the first end of lens 8 is lifted, the second end of lens 8 is lowered, the pitch angle of lens 8 is changed, until the length of adjusting bolt 13 of the first end of base 31 is longer than the length of adjusting bolt 13 of the second end of base 31, the pitch angle of lens 8 is changed to the elevation angle, further, by controlling the length of adjusting bolt 13 of the first end of base 31, the angle of the elevation angle of lens 8 is controlled.

[0080] The direction of the lens 8 deflection is distinguished as left and right. When the deflection angle of the lens 8 needs to be adjusted, specifically, from the initial position (the lens 8 is in the right state, and the adjusting screw 13 and the rotating shaft plate 12 have an adjusting gap), the adjusting screw 13 on the top screw seat 14 of the first end of the bottom plate seat 11 is rotated to drive the first end of the rotating shaft plate 12 to deflect left, the rotating shaft plate 12 rotates relative to the bottom plate seat 11 through the first rotating guide part 4, the second end of the rotating shaft plate 12 deflects right, thereby driving the first end of the lens 8 to deflect left, the second end of the lens 8 to deflect right, and further changing the left deflection angle of the lens 8. At the same time, the limiting screw 61 slides along the limiting groove 63, and the length of the adjusting screw 13 is controlled to control the angle of the left deflection angle of the lens 8. From the initial position (the lens 8 is in the right state, and the adjusting screw 13 and the rotating shaft plate 12 have an adjusting gap), the adjusting screw 13 on the top screw seat 14 of the second end of the bottom plate seat 11 is rotated to drive the second end of the rotating shaft plate 12 to deflect right, the rotating shaft plate 12 rotates relative to the bottom plate seat 11 through the first rotating guide part 4, the first end of the rotating shaft plate 12 deflects left, thereby driving the second end of the lens 8 to deflect right, the first end of the lens 8 to deflect left, and further changing the right deflection angle of the lens 8. At the same time, the limiting screw 61 slides along the limiting groove 63, and the length of the adjusting screw 13 is controlled to control the angle of the right deflection angle of the lens 8. From the initial position (the lens 8 is in the right state, and the adjusting screw 13 and the rotating shaft plate 12 have an adjusting gap), the adjusting screw 13 on the top screw seat 14 of the first end of the bottom plate seat 11 is first rotated to drive the first end of the rotating shaft plate 12 to deflect left, the rotating shaft plate 12 rotates relative to the bottom plate seat 11 through the first rotating guide part 4, the second end of the rotating shaft plate 12 deflects right, thereby driving the first end of the lens 8 to deflect left, the second end of the lens 8 to deflect right, and further changing the left deflection angle of the lens 8. At the same time, the limiting screw 61 slides along the limiting groove 63, and the length of the adjusting screw 13 is controlled to control the angle of the left deflection angle of the lens 8. Then the adjusting screw 13 on the top screw seat 14 of the second end of the bottom plate seat 11 is rotated to drive the second end of the rotating shaft plate 12 to deflect left, the rotating shaft plate 12 rotates relative to the bottom plate seat 11 through the first rotating guide part 4, the first end of the rotating shaft plate 12 deflects right, and further change the angle of the left deflection angle of the lens 8. At the same time, the limiting screw 61 slides along the limiting groove 63, until the length of the adjusting screw 13 on the second end of the bottom plate seat 11 is longer than the length of the adjusting screw 13 on the first end of the bottom plate seat 11, the deflection direction of the lens 8 is changed, the lens 8 is switched from left deflection to right deflection, and further the length of the adjusting screw 13 on the second end of the bottom plate seat 11 is controlled to control the angle of the right deflection angle of the lens 8.From the initial position (the lens 8 is in the right position, and the adjusting screw 13 and the rotating shaft plate 12 have an adjusting gap), first rotate the adjusting screw 13 on the top screw seat 14 of the second end of the bottom plate seat 11 to drive the second end of the rotating shaft plate 12 to swing left, and the rotating shaft plate 12 rotates relative to the bottom plate seat 11 through the first rotating guide part 4 to make the first end of the rotating shaft plate 12 swing right, thereby driving the second end of the lens 8 to swing left and the first end of the lens 8 to swing right, and further changing the right swing angle of the lens 8. At the same time, the limiting screw 61 slides along the limiting groove 63, the length of the adjusting screw 13 is controlled to control the angle of the right swing angle of the lens 8, and then the adjusting screw 13 on the top screw seat 14 of the first end of the bottom plate seat 11 is rotated to drive the first end of the rotating shaft plate 12 to swing left, and the rotating shaft plate 12 rotates relative to the bottom plate seat 11 through the first rotating guide part 4 to make the second end of the rotating shaft plate 12 swing right, thereby changing the angle of the right swing angle of the lens 8. At the same time, the limiting screw 61 slides along the limiting groove 63, until the length of the adjusting screw 13 on the first end of the bottom plate seat 11 is longer than the length of the adjusting screw 13 on the second end of the bottom plate seat 11, the swing direction of the lens 8 is changed, the lens 8 is switched from right swing to left swing, and the length of the adjusting screw 13 on the first end of the bottom plate seat 11 is further controlled to control the angle of the left swing angle of the lens 8.

[0081] The adjusting device of the medium-long lens arranged in the above manner realizes the bidirectional decoupling adjustment function, making the adjustment process simple and fast. The device uses a marking pin as a rotating shaft for high-precision guidance. This design not only ensures that the marking pin is stable and reliable during adjustment and is not easy to fall off, but also, due to the high-precision fit between the marking pin and the pin hole, the height of the lens 8 is not affected during adjustment, thereby realizing precise decoupling adjustment. In addition, this design also improves the speed and convenience of adjustment. The adjusting device adopts a flexible and rigid combined double-sided locking support method, effectively eliminating the influence of machining tolerance on adjustment accuracy and providing stable double-sided support, significantly enhancing the stability of the entire device. The design of the flexible pressing block 33 has a certain deformation allowance, which can adapt to lenses 8 with different outer diameter tolerances, which not only improves the universality of the device, but also helps to reduce the optical and mechanical machining cost of the lens 8. The design in the device allows a tolerance path to be set between the V-shaped groove, the flexible pressing block 33 and the lens 8, thereby ensuring the accurate axial positioning of the lens 8. This design not only improves the imaging quality and measurement accuracy of the optical system, but also enables the adjusting device to better meet the needs of high-precision optical detection. In summary, this adjusting device has the advantages of simple, fast and precise adjustment.

[0082] In a second aspect, the application provides an optical quantity detection device, which includes the above-mentioned long-medium lens adjusting device and a long-medium lens 8 used in cooperation with the device. The long-medium lens adjusting device can achieve high-precision pitch and yaw adjustment, ensuring the accurate alignment of the lens 8 at different angles, significantly improving the imaging quality of the optical system and the measurement accuracy, and making it better meet the needs of high-precision optical detection. In addition, the optical quantity detection device usually contains multiple key subsystems, such as light source, illumination, focusing, and light collection, etc. Among them, the light collection subsystem is particularly critical, which is responsible for collecting the scattered light generated by the wafer after being irradiated by the light source and imaging it onto the detector. Since there are a large number of lenses 8 in this subsystem, the requirements for the fixation, clamping, and collimation of the lens 8 are very strict. Accurate lens 8 adjusting device is crucial to ensure the performance of the entire optical quantity detection device, which directly affects the accuracy and reliability of the detection results. Through the adjusting device provided by the application, the efficiency and accuracy of the optical quantity detection device when performing complex detection tasks can be ensured.

[0083] In use, the long-medium lens 8 is placed on the support seat 32 of the adjusting device, and the long-medium lens 8 is preliminarily positioned through the support groove 321, then the flexible pressing block 33 is pressed on the long-medium lens 8, and the flexible pressing block 33 is fixed on the support seat 32 to limit the position of the long-medium lens 8. When the pitch angle of the long-medium lens 8 needs to be adjusted, the adjusting screw 13 on the base 31 is used for fine adjustment, and when the yaw angle of the long-medium lens 8 needs to be adjusted, the adjusting screw 13 on the top screw seat 14 is used for fine adjustment.
