The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] like Figure 1 and Figure 2As shown, this embodiment provides a lens life testing device for performing a rotational life test on a lens 100. The lens 100 includes a main body 101 and a rotating ring 102, which is rotatably disposed on the main body 101. Exemplarily, the rotating ring 102 may be a focusing ring or an actuating aperture ring on the lens 100.

[0043] Specifically, the lens life testing device includes a base 1, a clamping mechanism 2, and a driving mechanism 3. The clamping mechanism 2 is mounted on the base 1 and clamps and fixes the rotating ring 102, thereby limiting and fixing the lens 100. The driving mechanism 3 includes a first driving component 31, a torque limiter 32, and a connecting component 33. The fixed end of the first driving component 31 is mounted on the base 1, and the output end of the first driving component 31 is connected to the connecting component 33 via the torque limiter 32. The connecting component 33 is detachably connected to the main body 101. The first driving component 31 can drive the connecting component 33 to rotate, thereby causing the main body 101 to rotate relative to the rotating ring 102. This lens life testing device can replace manual testing of the workpiece's rotational life, effectively improving testing efficiency. Furthermore, by limiting the torsional torque through the torque limiter 32, it prevents damage to the lens 100 caused by excessive rotation angle of the main body 101, resulting in more standardized rotation angles and more accurate test results.

[0044] It should be noted that the torque limiter 32, also known as a safety coupling, limits the torque transmitted by the transmission system by slipping when the required torque exceeds a set value due to overload or mechanical failure (in this embodiment, this means the rotation angle of the main body 101 exceeds the maximum rotation angle of the rotating ring 102). It automatically reconnects after the overload condition disappears, thus effectively preventing mechanical damage. The structure and principle of the torque limiter 32 are existing technologies and will not be described in detail here.

[0045] Meanwhile, the lens 100 life test device uses a rotating ring 102 for fixing and the main body 101 is driven to rotate by the first driving component 31 to perform rotational life test. This effectively avoids the problem of damage to the rotating ring 102 and disengagement during the rotation test when the rotating ring 102 is clamped in the prior art, and greatly improves the efficiency and success rate of the test.

[0046] like Figure 3 and Figure 4As shown, the base 1 includes a mounting plate 12, a fixing plate 11, and two connecting plates 13. The mounting plate 12 and the fixing plate 11 are spaced apart, and the two connecting plates 13 are respectively connected between the two ends of the mounting plate 12 and the fixing plate 11 to form an installation space. The torque limiter 32 is disposed within the installation space. The first drive assembly 31 is disposed on the side of the mounting plate 12 opposite to the fixing plate 11, the connecting assembly 33 is disposed on the side of the fixing plate 11 opposite to the mounting plate 12, and the clamping mechanism 2 is disposed on the fixing plate 11. In this embodiment, the base 1 is a box structure, and the torque limiter 32 and the first drive assembly 31 are both disposed in the inner cavity of the box to provide safety protection for the torque limiter 32 and the first drive assembly 31 through the box. The fixing plate 11 is the top plate of the box, and the lens 100 to be tested and the clamping mechanism 2 are both disposed on the fixing plate 11 to facilitate operation by the operator.

[0047] Specifically, the fixed end of the first drive assembly 31 is fixed to the side of the mounting plate 12 opposite to the fixed plate 11. A through hole 121 is formed on the mounting plate 12 opposite to the torque limiter 32. The output shaft of the first drive assembly 31 passes through the through hole 121 and is connected to the input end of the torque limiter 32. For example, the first drive assembly 31 can be a motor. By setting a rotation angle range for the first drive assembly 31, the rotation of the main body 101 is made more standardized, and the test results are more accurate.

[0048] More specifically, the connecting assembly 33 includes a connecting shaft 331 and a rotating fixing member 332. The connecting shaft 331 is rotatably mounted on the fixing plate 11 and passes through the fixing plate 11. One end of the connecting shaft 331 is connected to the output end of the torque limiter 32, and the other end of the connecting shaft 331 is connected to the rotating fixing member 332. The rotating fixing member 332 is detachably connected to the main body 101. The output end of the torque limiter 32 is connected to the rotating fixing member 332 via the connecting shaft 331, making torque transmission more convenient and avoiding energy loss.

[0049] More specifically, the rotating fixing member 332 has a mounting slot 3321 on the side facing the lens 100, and a corresponding engaging part is provided on the main body 101, which can be inserted into and engaged in the mounting slot 3321. The rotating fixing member 332 can be a lens 100 bayonet fixture in the prior art, which can engage with the end of the lens 100 and be fixed relative to the lens 100, thereby driving the main body 101 of the lens 100 to rotate.

[0050] Optionally, continue to refer to Figures 1-4The clamping mechanism 2 includes a support member 21, a first gripper 22, and a second gripper 23. The support member 21 is disposed on the base 1, and the first gripper 22 and the second gripper 23 are movably disposed on the support member 21. The first gripper 22 and the second gripper 23 can move towards or away from each other to clamp or release the rotating ring 102. When the first gripper 22 and the second gripper 23 clamp the rotating ring 102, the operator can test the rotational life of the lens 100 to be tested by rotating the main body 101; when the first gripper 22 and the second gripper 23 release the rotating ring 102, the lens 100 to be tested can be replaced. At the same time, the first gripper 22 and the second gripper 23 can clamp lenses 100 of various specifications, effectively improving the compatibility and practicality of the lens 100 life testing device.

[0051] Specifically, the first gripper 22 includes a first connecting portion 221 and a first arcuate portion 222 connected together, and the second gripper 23 includes a second connecting portion 231 and a second arcuate portion 232 connected together. The first connecting portion 221 and the second connecting portion 231 are respectively movably disposed on the support member 21, and the first arcuate portion 222 and the second arcuate portion 232 can respectively abut against the outer wall of the rotating ring 102 to clamp the rotating ring 102. The first arcuate portion 222 and the second arcuate portion 232 are adapted to the shape of the rotating ring 102, resulting in a better clamping effect.

[0052] Furthermore, the first arc-shaped portion 222 and the second arc-shaped portion 232 can be made of materials such as silicone or rubber to increase the friction between the first arc-shaped portion 222, the second arc-shaped portion 232 and the rotating ring 102. Alternatively, an anti-slip portion can be provided on the side of the first arc-shaped portion 222 and the second arc-shaped portion 232 that faces each other, which also helps to improve the clamping force of the first arc-shaped portion 222 and the second arc-shaped portion 232 on the rotating ring 102.

[0053] More specifically, the clamping mechanism 2 further includes a second drive assembly 24, which is disposed on the support member 21. The output end of the second drive assembly 24 is connected to the first gripper 22 and the second gripper 23 respectively, and the second drive assembly 24 can drive the first gripper 22 and the second gripper 23 to move respectively. In this embodiment, the second drive assembly 24 may be a cylinder.

[0054] Understandably, the lens 100 has multiple rotating rings 102 (such as focus rings or actuation aperture rings) spaced apart along the axial direction, and the support member 21 is adjustablely positioned on the base 1. This configuration allows the clamping mechanism 2 to clamp the multiple rotating rings 102 individually by adjusting the position of the support member 21, while maintaining the connection between the drive mechanism 3 and the main body 101 of the lens 100, thereby enabling the testing of the rotational life of the multiple rotating rings 102.

[0055] Specifically, refer to Figure 3 and Figure 4 The clamping mechanism 2 also includes a lifting rod 25 and a locking member. The extension length of the lifting rod 25 is adjustablely disposed on the fixed plate 11, and the locking member is disposed on the fixed plate 11 to lock the lifting rod 25. A support member 21 is disposed at one end of the lifting rod 25 extending out of the fixed plate 11. In this embodiment, two lifting rods 25 are provided, and the two lifting rods 25 are respectively connected to the two ends of the support member 21 to ensure the force balance and support stability of the support member 21.

[0056] Optionally, continue to refer to Figure 1 and Figure 3 The lens 100 lifespan testing device also includes a control mechanism. The control mechanism includes a control component (not shown), a display screen 41, and a control button 42. The control component is housed within the base 1 and is communicatively connected to the display screen 41, the control button 42, the clamping mechanism 2, the first drive assembly 31, and the torque limiter 32. The control component can control the rotation angle, number of rotation steps, and number of rotations of the main body 101. The display screen 41 is located on the side of the base 1 facing the operator and can display the set number of rotation steps, the set target lifespan count, and the current number of rotations.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
