[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating relative importance or indicating the number of technical features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0044] like Figure 1 and Figure 2 As shown, a lens pressing ring locking device 100 provided by an embodiment of the utility model is used to fix a pressing ring 200 in a lens barrel 300. The pressing ring 200 is a component of a lens, and is generally used to press a lens 400 in the lens barrel 300. The pressing ring 200 can fix the lens 400 by means of threads. Optionally, the inner wall of the lens barrel 300 is provided with an internal thread, and the pressing ring 200 is provided with an external thread matching the internal thread. The pressing ring 200 is screwed into the lens barrel 300 in a threaded connection manner and pressed on the lens 400 in the lens barrel 300 to fix the lens 400. In addition, in this embodiment, the lens includes but is not limited to a camera lens or an industrial lens, etc.; the lens pressing ring locking device 100 provided by this embodiment has the advantages of high locking efficiency and high locking torque accuracy; the following is an explanation through specific implementation methods:

[0045] The lens pressing ring locking device 100 comprises:

[0046] A workbench 1, a lens barrel fixing mechanism 2 arranged on the workbench 1, a lens barrel rotating mechanism 3 transmission-connected to the lens barrel fixing mechanism 2, a lens fixing mechanism 4 arranged on the workbench 1, and a lens pressing ring locking mechanism 5 arranged on the workbench 1; the lens barrel fixing mechanism 2 is used to fix the lens barrel 300, the lens barrel rotating mechanism 3 is used to drive the lens barrel fixing mechanism 2 to rotate around the axis, the lens fixing mechanism 4 is used to fix the lens 400 in the lens barrel 300 relative to the lens barrel 300, and the lens pressing ring locking mechanism 5 is used to fix and screw the pressing ring 200 into the lens barrel 300.

[0047] The workbench 1 refers to a component used to realize the workpiece process. The workbench 1 is used to carry and fix various processing mechanisms. In this embodiment, the workbench 1 is provided with a lens barrel fixing mechanism 2, a lens barrel rotating mechanism 3, a lens fixing mechanism 4 and a lens pressing ring locking mechanism 5;

[0048] The lens barrel fixing mechanism 2 is a mechanism for fixing the lens barrel 300 , and the lens barrel fixing mechanism 2 fixes the lens barrel 300 on the workbench 1 ;

[0049] The lens barrel rotating mechanism 3 refers to a mechanism for rotating the lens barrel 300. The lens barrel rotating mechanism 3 is used to drive the lens barrel fixing mechanism 2 to rotate around the axis, and then the lens barrel fixing mechanism 2 drives the lens barrel 300 to rotate around the axis;

[0050] The lens fixing mechanism 4 is a mechanism for fixing the lens 400. The lens fixing mechanism 4 is used to fix the lens 400 in the lens barrel 300 to prevent the lens 400 from rotating when the pressing ring 200 is screwed into the lens barrel 300, thereby preventing the lens 400 from shifting or loosening.

[0051] The lens pressure ring locking mechanism 5 is a mechanism for locking the pressure ring 200 . The lens pressure ring locking mechanism 5 is used to fix the pressure ring 200 and screw the pressure ring 200 into the lens barrel 300 so that the pressure ring 200 is pressed onto the lens 400 .

[0052] like Figures 3 to 5 The working principle of the lens pressing ring locking device 100 provided in this embodiment is as follows:

[0053] The lens barrel 300 is fixed on the lens barrel fixing mechanism 2, and the lens 400 and the pressure ring 200 are placed in the lens barrel 300 in sequence, wherein the pressure ring 200 is located above the lens 400, the lens fixing mechanism 4 fixes the lens 400, and the lens pressure ring locking mechanism 5 fixes the pressure ring 200. At this time, the lens barrel rotating mechanism 3 drives the lens barrel fixing mechanism 2 to rotate around the axis, and the lens barrel fixing mechanism 2 drives the lens barrel 300 to rotate around the axis. Since the pressure ring 200 is fixed by the lens pressure ring locking mechanism, the pressure ring 200 rotates relative to the lens barrel 300, and the pressure ring 200 is screwed into the lens barrel 300 during the relative rotation process, so that the pressure ring 200 is locked and pressed on the lens 400.

[0054] By adopting the above technical solution, compared with the method of manually locking the lens pressure ring 200, the lens pressure ring locking device 100 of this embodiment has the advantages of high locking efficiency of the pressure ring 200 and good locking torque consistency.

[0055] Please also read Figure 6 and Figure 7 In one embodiment, the lens pressure ring locking mechanism 5 includes a locking block 51 , and the locking block 51 is provided with a buckling boss 511 for snapping into the force-bearing portion 201 of the pressure ring 200 .

[0056] Here, it can be understood that the force-bearing portion 201 of the pressure ring 200 is generally a force-bearing groove, that is, a force-bearing groove is opened in the circumferential direction of the pressure ring 200, and the locking block 51 is provided with a snap-in boss 511 that is snapped into the force-bearing groove, and the shape and size of the snap-in boss 511 match the shape and size of the force-bearing groove, so that the snap-in boss 511 is just snapped into the force-bearing groove, so that the pressure ring 200 is fixed relative to the locking block 51, and when the lens barrel rotating mechanism 3 drives the lens barrel 300 to rotate around the axis, since the pressure ring 200 is fixed relative to the locking block 51, the lens barrel 300 rotates relative to the pressure ring 200, and the pressure ring 200 can be screwed into the lens barrel 300.

[0057] It needs to be further explained that after the locking of the pressing ring 200 is completed, the buckle boss 511 can also be disengaged from the force-bearing groove of the pressing ring 200 to facilitate the locking of the next pressing ring 200.

[0058] By adopting the above technical solution, the locking block 51 fixes the pressure ring 200, which is beneficial to the locking operation.

[0059] In one embodiment, the lens pressure ring locking mechanism 5 also includes an adsorption cover 52 covered on the locking block 51, and an adsorption gap 53 is provided between the adsorption cover 52 and the locking block 51. The adsorption gap 53 is arranged around the locking block 51, and the adsorption gap 53 can generate negative pressure to adsorb and fix the pressure ring 200.

[0060] Here, it can be understood that an adsorption gap 53 is provided between the adsorption hood 52 and the locking block 51, and the adsorption gap 53 is arranged around the locking block 51, that is, the adsorption gap 53 extends along the circumference of the locking block 51, and the shape and size of the adsorption gap 53 match the shape and size of the pressure ring 200, so that the pressure ring 200 can just cover the adsorption gap 53. When the adsorption hood 52 is connected to the vacuum equipment, the vacuum equipment is turned on so that the adsorption gap 53 generates negative pressure to adsorb and fix the pressure ring 200, that is, the lens pressure ring locking mechanism 5 can adsorb and fix the pressure ring 200 and place the pressure ring 200 in the lens barrel 300. When the pressure ring 200 is screwed into the lens barrel 300, the vacuum equipment is turned off so that the locking block 51 is separated from the pressure ring 200.

[0061] By adopting the above technical solution, the lens pressure ring locking mechanism 5 can fix the pressure ring 200 by adsorption, thereby increasing the speed at which the pressure ring 200 is placed in the lens barrel 300.

[0062] Please refer again Figure 1 In one embodiment, the lens pressure ring locking device 100 also includes a locking lifting mechanism 6, which includes a locking lifting guide rail 61 and a locking lifting driving member 62 slidably arranged on the locking lifting guide rail 61. The locking lifting driving member 62 can be lifted and lowered along the locking lifting guide rail 61 to drive the lens pressure ring locking mechanism 5 to be lifted and lowered relative to the lens barrel fixing mechanism 2.

[0063] Here, it can be understood that the locking and lifting mechanism 6 is used to drive the lens pressure ring locking mechanism 5 to rise and fall relative to the lens barrel fixing mechanism 2. The lifting direction of the lens pressure ring locking mechanism 5 here refers to the direction in which the lens pressure ring locking mechanism 5 approaches or moves away from the lens barrel fixing mechanism 2. The lens pressure ring locking mechanism 5 is arranged above the lens barrel fixing mechanism 2, and the lens pressure ring locking mechanism 5 gradually approaches or moves away from the lens barrel fixing mechanism 2 when moving along the lifting direction.

[0064] Specifically, the locking lifting mechanism 6 includes a locking lifting guide rail 61 and a locking lifting drive 62. The length direction of the locking lifting guide rail 61 is parallel to the lifting direction. The locking lifting drive 62 can move along the length direction of the locking lifting guide rail 61. The locking lifting drive 62 is connected to the lens pressure ring locking mechanism 5 and is used to drive the lens pressure ring locking mechanism 5 to move along the lifting direction.

[0065] It needs to be further explained that the locking lifting drive component 62 includes but is not limited to a lifting motor or a lifting cylinder.

[0066] The working principle of the lens pressing ring locking device 100 of this embodiment is as follows:

[0067] Since the pressure ring 200 is connected to the lens barrel 300 by threads, as the pressure ring 200 is screwed into the lens barrel 300, the height of the pressure ring 200 relative to the lens barrel 300 gradually decreases. Therefore, the locking lifting mechanism 6 is required to drive the lens pressure ring locking mechanism 5 to descend synchronously, so as to keep the buckle boss 511 always stuck in the force-bearing part 201 of the pressure ring 200, so as to prevent the two from loosening during the process of screwing the pressure ring 200, causing the pressure ring 200 to be unable to be screwed into the lens barrel 300 normally.

[0068] By adopting the above technical solution, the locking and lifting mechanism 6 can make the pressing ring 200 move closer to or away from the lens barrel 300. At the same time, the locking and lifting mechanism 6 can improve the success rate of the pressing ring 200 being screwed into the lens barrel 300.

[0069] Please also read Figure 6 In one embodiment, the lens fixing mechanism 4 includes a pressure rod 41 for pressing on the lens 400 , and the locking block 51 is provided with a through hole 512 . The pressure rod 41 and the through hole 512 are clearance-matched, and the pressure rod 41 can be movably inserted into the through hole 512 .

[0070] Here, it can be understood that, since the pressure ring 200 is provided with an opening 202 facing the lens 400, when the pressure ring 200 is screwed into the lens barrel 300, the pressure rod 41 can pass through the opening 202 and press on the lens 400. Therefore, a through hole 512 is provided on the locking block 51, and the pressure rod 41 can pass through the through hole 512 and then pass through the opening 202 to press on the lens 400.

[0071] Specifically, the through hole 512 can be set along the central axis of the locking block 51 and penetrate the locking block 51, so that the pressure rod 41 is coaxially arranged with the locking block 51 when passing through the through hole 512, and the pressure rod 41 can be pressed on the center position of the lens 400, so that when the pressure rod 41 is pressed on the lens 400, the lens 400 is evenly stressed and is not prone to tilting.

[0072] By adopting the above technical solution, the pressing rod 41 can press on the lens 400 , thereby reducing the possibility of the lens 400 tilting or rotating in the lens barrel 300 .

[0073] In one embodiment, the lens pressure ring locking device 100 also includes a lens fixed lifting mechanism 7, which includes a lens fixed lifting guide rail 71 and a lens fixed lifting driving member 72 slidably arranged on the lens fixed lifting guide rail 71. The lens fixed lifting driving member 72 can be lifted and lowered along the lens fixed lifting guide rail 71 to drive the lens fixing mechanism 4 to be lifted and lowered relative to the lens barrel fixing mechanism 2, so that the pressure rod 41 can be lifted and lowered relative to the lens barrel fixing mechanism 2.

[0074] Here, it can be understood that the lens fixing lifting mechanism 7 is used to drive the lens fixing mechanism 4 to rise and fall relative to the lens barrel fixing mechanism 2. The lifting direction of the lens fixing mechanism 4 here refers to the direction in which the lens fixing mechanism 4 approaches or moves away from the lens barrel fixing mechanism 2. The lens fixing mechanism 4 is arranged above the lens barrel fixing mechanism 2, and the lens fixing mechanism 4 gradually approaches or moves away from the lens barrel fixing mechanism 2 when moving along the lifting direction.

[0075] Specifically, the lens fixing lifting mechanism 7 includes a lens fixing lifting guide rail 71 and a lens fixing lifting drive 72. The length direction of the lens fixing lifting guide rail 71 is parallel to the lifting direction. The lens fixing lifting drive 72 can move along the length direction of the lens fixing lifting guide rail 71. The lens fixing lifting drive 72 is connected to the lens fixing mechanism 4 and is used to drive the lens fixing mechanism 4 to move along the lifting direction, that is, the lens fixing lifting drive 72 is connected to the pressure rod 41 and is used to drive the pressure rod 41 to move along the lifting direction.

[0076] It needs to be further explained that the lens fixing lifting drive component 72 includes but is not limited to a lifting motor or a lifting cylinder.

[0077] By adopting the above technical solution, the lens fixing lifting mechanism 7 can drive the pressing rod 41 to press on the lens 400 , so as to fix the lens 400 in the lens barrel 300 .

[0078] Please also read Figure 8 In one embodiment, the lens barrel fixing mechanism 2 includes a lens barrel fixing base 21 and a plurality of lens barrel fixing blocks 22 arranged on the lens barrel fixing base 21. The plurality of lens barrel fixing blocks 22 are evenly arranged around the central axis of the lens barrel fixing base 21 and are provided with a clamping space for clamping the lens barrel 300.

[0079] Here, it can be understood that a clamping space is formed between the plurality of lens barrel fixing blocks 22 , and the lens barrel 300 is placed in the clamping space and the lens barrel fixing blocks 22 are brought close to each other to clamp the lens barrel 300 .

[0080] Specifically, the lens barrel rotating mechanism 3 is used to drive the central axis of the lens barrel fixing base 21 to rotate, so that the lens barrel fixing base 21 drives the plurality of lens barrel fixing blocks 22 to rotate around the axis, thereby driving the lens barrel 300 to rotate around the axis.

[0081] By adopting the above technical solution, the lens barrel fixing mechanism 2 includes a lens barrel fixing base 21 and a plurality of lens barrel fixing blocks 22. The plurality of lens barrel fixing blocks 22 can form a clamping space to clamp the lens barrel 300, and the structure of fixing the lens barrel 300 is simple and has high reliability. In addition, the plurality of lens barrel fixing blocks 22 are evenly arranged to press the central axis of the lens barrel fixing base 21, so that the force applied to the lens barrel 300 by each lens barrel fixing block 22 is equal, so that the lens barrel 300 is evenly stressed and is not prone to tilting, which causes the failure of the lens barrel 300 to cooperate with the pressing ring 200.

[0082] In one embodiment, each lens barrel fixing block 22 can move in a direction approaching or away from the central axis of the lens barrel fixing base 21 to adjust the size of the clamping space.

[0083] Here, it can be understood that the lens barrel 300 can be clamped in the clamping space, and the lens barrel fixing block 22 can adjust the distance between itself and the central axis of the fixed base to adjust the size of the clamping space, thereby adapting to lens barrels 300 of different sizes, thereby improving the applicability of the lens barrel fixing mechanism 2.

[0084] By adopting the above technical solution, the lens barrel fixing mechanism 2 can be applicable to lens barrels 300 of different sizes, thereby improving the applicability of the lens barrel fixing mechanism 2 .

[0085] In one embodiment, the locking block 51 , the adsorption cover 52 , the pressure rod 41 and the lens barrel fixing base 21 are arranged based on the same axis.

[0086] Here, it can be understood that the locking block 51, the adsorption cover 52, the pressure rod 41, and the lens barrel fixed base 21 are located on the same axis; preferably, the locking block 51, the adsorption cover 52, the pressure rod 41 and the lens barrel fixed base 21 are coaxially arranged.

[0087] By adopting the above technical solution, the degree of coordination among the locking block 51, the adsorption cover 52, the pressing rod 41 and the lens barrel fixing base 21 is improved.

[0088] In a second aspect, a lens assembly system is provided, including a lens barrel moving device and the above-mentioned lens pressure ring locking device 100, wherein the lens barrel moving device is used to move the lens barrel 300 onto the lens pressure ring locking device 100.

[0089] By adopting the above technical solution, on the basis of having the advantages of the lens pressure ring locking device 100 of the above embodiment, the lens assembly system of this embodiment also has the advantage of high assembly efficiency.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
