[0030] An embodiment of the present application discloses an adjusting device, which is mainly applied to an optical detection device and is used to realize the position adjustment and locking of an optical element 30. The optical element 30 can be an objective lens or a lens barrel.

[0031] For the adjusting device disclosed in the embodiment of the present application, please refer to Figures 1 to 4 , which includes a carrier 10, a mounting base 20, and an adjusting assembly 40. The carrier 10 is used to install and fix the optical element 30. The carrier 10 has an optical channel. The outer contour shape of the carrier 10 can be a cylindrical structure with openings at both ends. The internal channel of the carrier 10 forms the optical channel. One or more optical elements 30 are all located in the optical channel. The optical elements 30 can be installed and fixed on the carrier 10 by means of threaded connection or snap connection. The mounting base 20 has a mounting hole 211, and the carrier 10 can be installed in the mounting hole 211 to realize the assembly of the carrier 10 and the mounting base 20. In an embodiment where the carrier 10 is a cylindrical structure and the mounting hole 211 is a circular hole, the carrier 10 can be coaxially arranged with the mounting hole 211, and at the same time, the optical channel in the carrier 10 is also coaxially arranged with the mounting hole 211 to avoid the carrier 10 or the mounting base 20 affecting the optical path transmission.

[0032] The adjusting assembly 40 is connected to the mounting base 20. The adjusting assembly 40 includes a plurality of flexible arms 41. The flexible arms 41 surround the mounting hole 211. The flexible arms 41 have a tightened state on the load-bearing member 10 and the tightened state is adjustable. In one embodiment, please refer to Figures 1 to 4 , the adjusting assembly 40 can be integrally formed with the mounting base 20. The mounting base 20 has a base body 21. The mounting hole 211 is provided on the base body 21. The flexible arms 41 in the adjusting assembly 40 can be integrally formed with the base body 21. Or in other embodiments, the flexible arms 41 can also be installed on the base body 21 through fasteners to realize the connection between the adjusting assembly 40 and the mounting base 20.

[0033] In some embodiments, please continue to refer to Figures 1 to 4 , the flexible arms 41 are arranged to surround the mounting hole 211. The mounting hole 211 can be a circular hole. The flexible arms 41 extend circumferentially around the mounting hole 211. The flexible arms 41 have a connection end 411 and a suspension end 412 in their extending direction. The connection end 411 of the flexible arm 41 is connected to the base body 21 through a fastener or integrally formed with the base body 21 in the circumferential direction of the mounting hole 211.

[0034] The number of flexible arms 41 in the adjusting assembly 40 can be set to one, two or more than three. Each flexible arm 41 extends circumferentially around the mounting hole 211. The multiple flexible arms 41 are arranged at intervals in the circumferential direction of the mounting hole 211 so that the flexible arms 41 form a structure surrounding the mounting hole 211. Each flexible arm 41 has an inner wall surface surrounding the mounting hole 211. This inner wall surface can be coplanar with the hole wall surface of the mounting hole 211 on the base body 21, so as to facilitate the integral formation of the flexible arm 41 and the base body 21.

[0035] In the embodiment where there is one flexible arm 41 in the adjusting assembly 40 or the number of flexible arms 41 in the adjusting assembly 40 is multiple and odd, the suspension end 412 of the flexible arm 41 can have a clearance with the base body 21 in the circumferential direction of the mounting hole 211. The suspension end 412 of the flexible arm 41 can be movably connected to the base body 21 through a bolt (not shown in the figure). Tightening the bolt can reduce the clearance. At the same time, the inner wall surface of the flexible arm 41 can be pressed against the outer peripheral surface 112 of the load-bearing member 10 to realize the tightening of the flexible arm 41 on the load-bearing member 10. The size of the above clearance is related to the tightening degree of the flexible arm 41 on the load-bearing member 10. The size of the clearance can be changed by screwing the bolt to adjust the tightening degree of the flexible arm 41 on the load-bearing member 10, so as to facilitate the locking of the load-bearing member 10 through the flexible arm 41. For example, loosening the bolt increases the clearance to reduce the tightening degree of the flexible arm 41 on the load-bearing member 10, and tightening the bolt reduces the clearance to increase the tightening degree of the flexible arm 41 on the load-bearing member 10.

[0036] In an embodiment in which a plurality of flexible arms 41 are provided in the adjusting assembly 40, please refer to Figures 1 to 4 , the plurality of flexible arms 41 are arranged in a ring and spaced apart in the radial plane of the mounting hole 211. Two adjacent flexible arms 41 among the plurality of flexible arms 41 are arranged in pairs. The suspension ends 412 of two adjacent flexible arms 41 arranged in pairs are arranged opposite to each other in the circumferential direction of the mounting hole 211. An activity gap 42 is formed between the two opposite suspension ends 412. The two opposite suspension ends 412 can be movably connected by bolts. Tightening the bolts can reduce the activity gap 42, and at the same time, the inner wall surface of the flexible arm 41 can be pressed against the outer peripheral surface 112 of the carrier 10, so as to realize the clamping of the carrier 10 by the flexible arm 41. The size of the activity gap 42 between the two opposite suspension ends 412 is related to the clamping degree of the two flexible arms 41 arranged in pairs on the carrier 10. The size of the activity gap 42 can be changed by screwing the bolts to adjust the clamping degree of the flexible arm 41 on the carrier 10, so as to facilitate the locking of the carrier 10 by the flexible arm 41. For example, loosening the bolts increases the activity gap 42 to reduce the clamping degree of the flexible arm 41 on the carrier 10, and tightening the bolts reduces the activity gap 42 to increase the clamping degree of the flexible arm 41 on the carrier 10.

[0037] Please refer to Figures 1 to 4 , the flexible arm 41 extends in the circumferential direction of the mounting hole 211. The flexible arm 41 is spaced apart from the base body 21 on both axial sides of the mounting hole 211. The flexible arm 41 is provided with a deflection groove 414 on one axial side of the mounting hole 211. The outside of the carrier 10 has an outer peripheral surface 112. In an embodiment in which the carrier 10 is a cylindrical structure, the outer side surface of the carrier 10 forms its outer peripheral surface 112.

[0038] In the state where the flexible arm 41 is tightening the carrier 10, as the flexible arm 41 is tightening the carrier 10, that is, as the flexible arm 41 is locking the carrier 10, the flexible arm 41 is pressed against the carrier 10 so that the inner wall surface of the flexible arm 41 is in contact with the outer peripheral surface 112 of the carrier 10. Under the action of the deflection groove 414 on the flexible arm 41, the flexible arm 41 can produce displacement deformation in the axial direction of the mounting hole 211. In the process of the displacement deformation of the flexible arm 41, the static friction force applied by the flexible arm 41 to the carrier 10 forms a displacement effect on the carrier 10. The direction of the displacement force is the same as the displacement deformation direction of the carrier 10. Under the displacement force applied by the flexible arm 41 to the carrier 10, the position of the carrier 10 in the axial direction of the mounting hole 211 can be changed, thereby realizing the adjustment of the axial position of the carrier 10 and the optical element 30 in the mounting hole 211. In this way, the carrier 10 and the optical element 30, that is, the adjustment of the axial position of the optical element in the mounting hole 211 is realized during the locking process of the carrier 10 and the optical element 30, thereby effectively avoiding the position deviation of the optical element in the optimal position during the locking process.

[0039] Please refer to Figure 4 Stress change diagram, the outer contour of the line is the structure of the adjustment device before the flexible arm 41 is connected and the flexible arm 41 is not tightened to the carrier 10, the colored entity is the structure of the adjustment device after the flexible arm 41 is connected and the flexible arm 41 is in the tightened state, Figure 4 It can be seen that after the flexible arm 41 is tightened, the deformation of the flexible arm 41 can exert a displacement force on the carrier 10, thereby driving the carrier 10 to move axially in the mounting hole 211, so that the position of the carrier 10 in the axial direction of the mounting hole 211 is different before and after the flexible arm 41 is tightened, thereby realizing the adjustment of the axial position of the carrier 10 in the mounting hole 211.

[0040] For some examples, please refer to Figures 1 to 4 The deflection groove 414 provided on the flexible arm 41 is related to the displacement deformation generated by the flexible arm 41 in the tightened state. When the flexible arm 41 is in the tightened state, the flexible arm 41 generates a displacement deformation toward one side away from the deflection groove 414, so that the direction of the deflection groove 414 is opposite to the direction of the displacement force applied by the flexible arm 41 to the carrier 10 in the tightened state.

[0041] Specifically, in one embodiment, please refer to Figures 1 to 4, a deflection groove 414 can be provided on each flexible arm 41, and the flexible arm 41 is extended in the circumferential direction of the mounting hole 211 when the flexible arm 41 is not tightened, and the deflection groove 414 on the flexible arm 41 is located on one side of the flexible arm 41 in the extension direction of the flexible arm 41, and the flexible arm 41 has edges on both sides of its extension direction, and the notch of the deflection groove 414 is located on one side edge of the flexible arm 41, and the notch direction of the deflection groove 414 is perpendicular to the extension direction of the flexible arm 41, and the notch direction of the deflection groove 414 is consistent with the setting direction of the deflection groove 414 on the flexible arm 41; the depth direction of the deflection groove 414, that is, the direction from the notch of the deflection groove 414 to the bottom of the groove can be perpendicular to the extension direction of the flexible arm 41, and can also gradually tilt toward the suspended end 412 of the flexible arm 41 from the bottom of the groove 414 to the notch. In any case, as long as the slot of the deflection slot 414 is located on one side edge of the flexible arm 41, it can be considered that the direction of the deflection slot 414 is perpendicular to the extension direction of the flexible arm 41, that is, when the flexible arm 41 is not tightened, the direction of the deflection slot 414 is parallel to the axial direction of the mounting hole 211.

[0042] The deflection groove 414 is located on one side of the flexible arm 41 in the extension direction of the vertical flexible arm 41. The setting direction of the deflection groove 414 on the flexible arm 41 is consistent with the direction of the deflection groove 414 and is perpendicular to the extension direction of the flexible arm 41. In this way, when the flexible arm 41 is in a tightened state, the notch of the deflection groove 414 is enlarged, and the side with the deflection groove 414 provided in the extension direction of the vertical flexible arm 41 is stretched in the extension direction of the flexible arm 41 greater than the side without the deflection groove 414. In this way, the suspended end 412 of the flexible arm 41 will bend and deform in the axial direction of the mounting hole 211 toward the side with the deflection groove 414, that is, the flexible The arm 41 produces a displacement deformation on the side facing away from the deflection groove 414. The direction of the displacement deformation of the flexible arm 41 is consistent with the direction of the displacement force applied by the flexible arm 41 to the carrier 10. In this way, the direction of the deflection groove 414 or the setting direction of the deflection groove 414 relative to the flexible arm 41 is opposite to the direction of the displacement force applied by the flexible arm 41 to the carrier 10, that is, the position adjustment direction of the carrier 10 is opposite to the direction or setting direction of the deflection groove 414 on the flexible arm 41. The position adjustment direction of the carrier 10 can be freely selected according to the direction or setting direction of the deflection groove 414, which facilitates the axial position adjustment of the carrier 10 in the mounting hole 211.

[0043] In other embodiments, the position adjustment of the carrier 10 in the axial direction of the mounting hole 211 can be achieved by setting the shape of the movable gap 42 between the two suspension ends 412 arranged opposite to each other in the circumferential direction of the mounting hole 211 or the movable gap between the suspension end 412 and the base body 21.

[0044] In one embodiment, the active gap is trapezoidal when the flexible arm 41 is not tightened. The two suspension ends 412 or the two faces of the suspension end 412 and the base body 21 that are opposite in the circumferential direction of the mounting hole 211 correspond to the two waists of the trapezoid. The two suspension ends 412 or the suspension end 412 and the base body 21 are connected by bolts. During the process of screwing the bolts to tighten the flexible arm 41, the two faces of the two suspension ends 412 or the suspension end 412 and the base body 21 that are opposite in the circumferential direction of the mounting hole 211 gradually approach the fitting position. In this way, the stretching dimension of the flexible arm 41 on one side perpendicular to its extending direction is greater than that on the other side. The suspension end 412 of the flexible arm 41 is bent and deformed toward the side with the smaller stretching dimension. During the bending deformation of the flexible arm 41, the flexible arm 41 exerts a displacement acting force on the carrier 10 to make the carrier 10 move toward the side with less bending deformation, thereby realizing the position adjustment of the carrier 10 in the axial direction of the mounting hole 211. In this way, the position adjustment direction of the carrier 10 can be freely selected according to the shape of the active gap, which is convenient for the position adjustment of the carrier 10 in the axial direction of the mounting hole 211.

[0045] In some embodiments, please refer to Figures 1 to 4 , in the adjusting assembly 40, the acting force direction exerted by the flexible arm 41 on the carrier 10 is parallel to the axial direction of the mounting hole 211, and the displacement acting force directions exerted by multiple flexible arms 41 on the carrier 10 are the same, so as to ensure that the displacement acting forces exerted by each flexible arm 41 on the carrier 10 are all used to adjust the position of the carrier 10 in the axial direction of the mounting hole 211, thereby realizing better adjustment of the positions of the carrier 10 and the optical element 30 in the axial direction of the mounting hole 211.

[0046] In one embodiment, multiple flexible arms 41 are arranged around the mounting hole 211 in the radial plane of the mounting hole 211. In this way, the displacement acting force points exerted by multiple flexible arms 41 on the carrier 10 can be arranged at intervals in the circumferential direction of the mounting hole 211, and the displacement acting force points exerted by the flexible arm 41 on the carrier 10 can be arranged at intervals and evenly in the circumferential direction of the mounting hole 211. This helps to make the force on the carrier 10 uniform in the circumferential direction of the mounting hole 211, and can reduce the angle of inclination of the axis of the carrier 10 relative to the axis of the mounting hole 211 due to the position adjustment of the carrier 10 in the axial direction of the mounting hole 211, thereby improving the position adjustment accuracy of the carrier 10 and the optical element 30 in the axial direction of the mounting hole 211.

[0047] In some embodiments, please refer to Figures 1 to 4, two flexible arms 41 in the adjusting assembly 40 can be provided. The suspension ends 412 of the two flexible arms 41 are arranged opposite to each other in the circumferential direction of the mounting hole 211. In this way, the displacement acting force exerted by the flexible arms 41 on the carrier 10 only acts near the movement gap 42. Under the displacement acting force, the carrier 10 can not only achieve position adjustment in the axial direction of the mounting hole 211, but also the axis of the carrier 10 will deflect by a small angle relative to the axis of the mounting hole 211. And under the long-term unilateral displacement acting force, the carrier 10 may deviate from the optimal position after locking.

[0048] In one embodiment, in order to prevent the carrier 10 from deviating from the optimal position after locking under the long-term unilateral displacement acting force, the number of the adjusting assemblies 40 can be set to at least two, that is, the number of the adjusting assemblies 40 can be set to two, three or more than four. The multiple adjusting assemblies 40 are arranged at intervals in the axial direction of the mounting hole 211. Please continue to refer to Figures 1 to 4 , wherein the displacement acting forces exerted on the carrier 10 by two of the adjusting assemblies 40 are opposite in direction and both parallel to the axial direction of the mounting hole 211. In this way, it is possible to prevent the carrier 10 from bearing a large long-term unilateral displacement acting force, that is, it is possible to prevent the carrier 10 from deviating from the optimal position after locking, thereby improving the position stability of the carrier 10 and the optical element 30 after locking.

[0049] Furthermore, in order to reduce the deflection angle of the axis of the carrier 10 relative to the axis of the mounting hole 211 during the position adjustment of the carrier 10, in the embodiment in which the displacement acting forces exerted on the carrier 10 by the two adjusting assemblies 40 are opposite in direction and parallel to the axial direction of the mounting hole 211, it is also provided that the acting points of the displacement acting forces exerted on the carrier 10 by one of the two adjusting assemblies 40 coincide with the acting points of the displacement acting forces exerted on the carrier 10 by the other adjusting assembly 40 in the circumferential direction of the mounting hole 211. In this way, the deflection of the axis of the carrier 10 relative to the axis of the mounting hole 211 under the displacement acting force of one of the adjusting assemblies 40 can be suppressed by the displacement acting force exerted on the bearing capacity by the other adjusting assembly 40, thereby reducing the deflection angle of the axis of the carrier 10 relative to the axis of the mounting hole 211.

[0050] In order to make the acting points of the displacement acting forces with opposite directions applied by the two adjusting components 40 to the carrier 10 coincide in the circumferential direction of the mounting hole 211, in the embodiments where one or two flexible arms 41 are provided in each adjusting component 40, the movement clearances between one flexible arm 41 and the base body 21 or between the two flexible arms 41 in one adjusting component 40 are arranged corresponding to the movement clearances between one flexible arm 41 and the base body 21 or between the two flexible arms 41 in the other adjusting component 40 in the circumferential direction of the mounting hole 211; in the embodiments where there are more than three flexible arms 41 in each adjusting component 40, at least part of the movement clearances in one adjusting component 40 are arranged corresponding to each of the movement clearances in the other adjusting component 40 in the circumferential direction of the mounting hole 211. In this way, during the axial position adjustment of the carrier 10 in the mounting hole 211, the two adjusting components 40 with opposite displacement acting forces can reduce the deflection angle of the axis of the carrier 10 relative to the axis of the mounting hole 211.

[0051] In some other embodiments, in order to reduce the deflection angle of the axis of the carrier 10 relative to the axis of the mounting hole 211, in the same adjusting component 40, the displacement acting force applied by one of the two flexible arms 41 forming the movement clearance 42 to the carrier 10 can be set to be opposite to the displacement acting force applied by the other flexible arm 41 to the carrier 10, so as to apply a torque around the central position of the movement clearance 42 to the carrier 10 through these two flexible arms 41, thereby suppressing the deflection of the axis of the carrier 10 under the displacement acting forces of other flexible arms 41.

[0052] In some other embodiments, when the carrier 10 can withstand the unilateral continuous displacement acting force for a long time without deviating from the optimal position, the number of adjusting components 40 can be set to two and arranged at intervals in the axial direction of the mounting hole 211. The directions of the displacement acting forces applied by the adjusting components 40 to the carrier 10 are the same. The acting point of the displacement acting force applied by one adjusting component 40 to the carrier 10 is arranged opposite to the acting point of the displacement acting force applied by the other adjusting component 40 to the carrier 10 in the radial direction of the mounting hole 211, that is, at least part of the movement clearances 42 in one adjusting component 40 are arranged opposite to each of the movement clearances 42 in the other adjusting component 40 in the radial direction of the mounting hole 211. In this way, the deflection of the axis of the carrier 10 under the displacement acting forces of some flexible arms 41 can also be suppressed.

[0053] In some embodiments, the optical element 30 can be fixed on the carrier 10, and the carrier 10 can be pre-positioned in the mounting hole 211 of the mounting base 20. The bolts that tighten the flexible arm 41 in the adjustment assembly 40 can be screwed to lock the carrier 10 in the mounting base 20, and the axial position of the carrier 10 in the mounting hole 211 can be adjusted. This can prevent the carrier 10 and the optical element 30 from deviating from the optimal position during the locking process.

[0054] In one embodiment, please refer to Figure 2 The carrier 10 and the mounting base 20 are held against each other in the axial direction of the mounting hole 211. The mounting base 20 includes a base body 21 and a connecting flange 22. The mounting hole 211 is located on the base body 21. The connecting flange 22 can be installed on the base body 21 at one end opening in the axial direction of the mounting hole 211 by screws. The carrier 10 includes a carrier body 11. The carrier body 11 is generally a cylindrical structure. The optical element 30 is installed in the carrier body 11. The carrier body 11 can be inserted into the base from one axial side of the mounting hole 211. In the seat body 21, the outer peripheral surface 112 of the carrier 10 is also the outer peripheral surface of the carrier body 11. The outer peripheral surface of the carrier body 11 is in contact with the inner wall surface of the mounting base 20 in a clamped state; the carrier body 11 has an outer flange 111 at one end in its extension direction, and the outer flange 111 can respectively abut against the base body 21 and the connecting flange 22 in the axial direction of the mounting hole 211, thereby limiting the carrier 10 from escaping from the mounting hole 211, and realizing the pre-positioning of the carrier 10 in the mounting base 20.

[0055] In one embodiment, please refer to Figure 2 The carrier 10 also includes a limiting member 12, and a limiting hole 212 is provided on the hole wall of the mounting hole 211 on the base body 21. The limiting hole 212 is a through-hole that penetrates the hole wall in the radial direction of the mounting hole 211. After the carrier body 11 is installed in the mounting hole 211, the carrier body 11 has a threaded hole corresponding to the position of the limiting hole 212. The limiting member 12 can be a limiting pin with a threaded connection portion. The limiting member 12 can pass through the limiting hole 212 and be connected to the threaded hole on the outer wall of the carrier body 11. In this way, the limiting member 12 is located in the limiting hole 212, one end of the limiting member 12 is located in the mounting hole 211 and connected to the carrier body 11, and the other end is located outside the mounting hole 211. The limiting member 12 is screwed to realize that the limiting member 12 and the carrier body 11 are pressed tightly against the hole wall of the base body 21, thereby realizing the pre-positioning of the carrier 10 and the mounting base 20.

[0056] Further, in one embodiment, the limiting hole 212 can be set as an elongated hole extending in the axial direction of the mounting hole 211, or the limiting hole 212 can be set as an arc-shaped hole extending in the circumferential direction of the mounting hole 211 and inclined towards one axial end of the mounting hole 211. By changing the position of the limiting member 12 in the limiting hole 212, the carrying body 11 can be driven to move in the axial direction of the mounting hole 211 by the limiting member 12, so as to realize the coarse adjustment of the positions of the carrier 10 and the optical element 30 in the axial direction of the mounting hole 211. In addition, by tightening the limiting member 12, the pre-positioning of the carrier 10 and the optical element 30 in the axial direction of the mounting hole 211 can be realized.

[0057] The embodiment of the present application also discloses an optical detection device, which includes an optical element 30 and the adjusting device in any of the above embodiments. The optical element 30 can be an objective lens or a lens barrel. The optical element 30 is fixed on the carrier 10 of the adjusting assembly 40. The optical element 30 can receive and transmit the light in the optical channel of the carrier 10. By adjusting the axial position of the carrier 10 in the mounting hole 211 of the mounting base 20, the position of the optical element 30 in the axial direction of the mounting hole 211 can be changed, so as to achieve different imaging effects.
