The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0040] like Figure 1 and Figure 2 As shown, a lens aperture testing device provided by an embodiment of the utility model comprises:

[0041] A workbench 1, a rotating mechanism 2 arranged on the workbench 1, a fixing mechanism 3 arranged on the rotating mechanism 2, a testing mechanism 4 arranged on the fixing mechanism 3, and an identification mechanism 5 arranged opposite to the fixing mechanism 3; the fixing mechanism 3 is used to fix the diaphragm 6 to be tested, the testing mechanism 4 is used to test the diaphragm 6 fixed on the fixing mechanism 3, the fixing mechanism 3 is defined with a testing position and an identification position, the rotating mechanism 2 is used to drive the fixing mechanism 3 to switch to the testing position or the identification position, and the identification mechanism 5 is used to obtain and analyze the image of the diaphragm 6.

[0042] Here, it can be understood that the workbench 1 refers to a component for fixing the rotating mechanism 2, the fixing mechanism 3, the testing mechanism 4 and the identification mechanism 5;

[0043] The fixing mechanism 3 refers to a component for fixing the diaphragm 6 to be tested; the fixing mechanism 3 is defined with a test position and an identification position, the test position refers to a position where the diaphragm 6 is fixed by the fixing mechanism 3 to simulate the actual use of the diaphragm 6, in this embodiment, the test position refers to a position where the central axis of the diaphragm 6 is parallel to the horizontal plane when the diaphragm 6 is fixed, so as to simulate the actual use process of the diaphragm 6; the identification position refers to a position where the diaphragm 6 is fixed by the fixing mechanism 3 for image recognition, in this embodiment, the identification position refers to a position where the central axis of the diaphragm 6 is vertical to the horizontal plane when the diaphragm 6 is fixed, that is, the diaphragm 6 is in a horizontal state, so as to facilitate recognition by the identification mechanism 5;

[0044] The testing mechanism 4 refers to a component for testing the diaphragm 6 fixed on the fixing mechanism 3; in the present embodiment, the testing mechanism 4 refers to a component capable of driving the lever of the diaphragm 6 to rotate back and forth, and the real use process of the diaphragm 6 is simulated by reciprocatingly rotating the lever of the diaphragm 6.

[0045] The rotating mechanism 2 refers to a component used to drive the diaphragm 6 to rotate around the axis; the rotating mechanism 2 is arranged on the workbench 1, and the rotating mechanism 2 includes but is not limited to a rotating motor; the rotating mechanism 2 is used to drive the fixing mechanism 3 to switch to the test position or the identification position;

[0046] The identification mechanism 5 refers to a component used to obtain the image of the aperture 6 so as to analyze the state of the aperture 6 after the test; in this embodiment, the identification mechanism 5 generally refers to an image recognition mechanism 5, which obtains the image of the aperture 6 through a camera, and then analyzes and identifies the image through a processor, thereby obtaining the state of the aperture 6.

[0047] The working principle of the lens aperture test device provided in this embodiment is as follows:

[0048] like Figure 2 As shown, the rotating mechanism 2 rotates the fixing mechanism 3 to the identification position, fixes the diaphragm 6 on the fixing mechanism 3, and the identification mechanism 5 obtains the image of the diaphragm 6, and then identifies the state of the diaphragm 6; Figure 1 As shown, the fixing mechanism 3 is then rotated to the test position by the rotating mechanism 2, and the testing mechanism 4 tests the diaphragm 6 at the test position; after the diaphragm 6 is tested, the rotating mechanism 2 rotates the fixing mechanism 3 to the identification position, and the identification mechanism 5 obtains the image of the diaphragm 6, and then identifies the state of the diaphragm 6. By adopting the above technical solution, the rotating mechanism 2 can switch the fixing mechanism 3 to the test position and the identification position. When the fixing mechanism 3 is located at the identification position, the diaphragm 6 is in a horizontal state, so it is convenient for the operator to disassemble and install the diaphragm 6, which improves the convenience of operation; at the same time, the test position is different from the identification position, so that the test position can be set at a position where the diaphragm 6 simulates real use, which improves the simulation reality of the test. In addition, the identification position can also be set at a position that is conducive to identifying the diaphragm 6, which improves the recognition accuracy.

[0049] In one embodiment, the fixing mechanism 3 is switched to the testing position so that the central axis of the aperture 6 on the fixing mechanism 3 is parallel to the surface of the workbench 1 .

[0050] Here, it can be understood that when the fixing mechanism 3 is rotated to the test position, the central axis of the diaphragm 6 on the fixing mechanism 3 is parallel to the surface of the workbench 1, and the surface of the workbench 1 is generally parallel to the horizontal plane. In this way, the central axis of the diaphragm 6 is generally parallel to the horizontal plane during testing, simulating the placement position of the diaphragm 6 during actual use.

[0052] In one embodiment, the fixing mechanism 3 is switched to the identification position so that the central axis of the aperture 6 on the fixing mechanism 3 is perpendicular to the surface of the workbench 1 , and the aperture 6 is arranged opposite to the identification mechanism 5 .

[0053] Here, it can be understood that when the fixing mechanism 3 rotates to the identification position, the central axis of the aperture 6 on the fixing mechanism 3 is perpendicular to the surface of the workbench 1, and the surface of the workbench 1 is generally parallel to the horizontal plane. In this way, the central axis of the aperture 6 is generally perpendicular to the horizontal plane during identification, which is beneficial for the identification mechanism 5 to obtain the image of the aperture 6.

[0054] Specifically, the central axis of the aperture 6 is perpendicular to the horizontal plane, that is, the aperture 6 is in a horizontal state, and the recognition mechanism 5 can obtain the image of the aperture 6 vertically downward from above the aperture 6, thereby reducing image distortion and improving recognition accuracy.

[0055] By adopting the above technical solution, the recognition accuracy of the recognition mechanism 5 is improved.

[0058] By adopting the above technical solution, the switching of the fixing mechanism 3 between the test position and the identification position is achieved.

[0059] In one embodiment, the rotating bracket 21 is arranged perpendicularly to the surface of the workbench 1, the rotating driving member 22 is arranged on the rotating bracket 21 and has a power output shaft 221 perpendicular to the rotating bracket 21, and the rotating frame 23 is connected to the power output shaft 221 and can rotate around the power output shaft 221.

[0062] In one embodiment, the fixing mechanism 3 includes a first fixing frame 31, a second fixing frame 32 and a clamping mechanism 33.

The second fixing frame 32 is vertically arranged on the first fixing frame 31 and parallel to the power output shaft 221. The clamping mechanism 33 is arranged on the second fixing frame 32.

[0063] Here, it can be understood that the fixing mechanism 3 designed as above can make the first fixing frame 31 , the second fixing frame 32 and the clamping mechanism 33 in an open state, which is beneficial to the installation and removal of the diaphragm 6 .

The first clamping member 333 and the second clamping member 334 are slidably arranged on the clamping guide rail 331.

The first clamping member 333 and the second clamping member 334 move toward each other to clamp the aperture 6, or the first clamping member 333 and the second clamping member 334 move away from each other to release the aperture 6.

[0066] Here, it can be understood that the clamping guide rail 331 is used to guide the first clamping member 333 and the second clamping member 334 to move toward or away from each other to achieve the clamping or loosening of the aperture 6; the first clamping drive member 335 and the second clamping drive member 336 are respectively used to provide power for the movement of the first clamping member 333 and the second clamping drive member 334, and the first clamping drive member 335 and the second clamping drive member 336 generally refer to motors, which drive the first clamping member 333 and the second clamping member 334 to move through belt transmission.
