Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a lens vibration testing device. Background Technology

[0002] As the application range of lenses continues to expand, users have increasingly stringent requirements for lens quality. Therefore, before delivery, finished lenses need to undergo random vibration tests to ensure that the lens structure and performance meet user needs.

[0003] The purpose of vibration testing is to verify whether a lens will experience defocusing, zoom issues, or loss of focus under conditions of high vibration. If these occur, it indicates that the lens's performance does not meet requirements. Therefore, during lens vibration testing, the lens needs to be placed at the same height as the test chamber window, and the chip should be fixed to the rear end of the lens for the vibration test. Verification requires taking chart images before and after the test for comparison, as well as capturing actual images during the test. Because the lens tailplate cannot be locked to the chip, existing testing equipment cannot meet the testing requirements, causing errors in test accuracy and affecting the test results.

[0004] Therefore, there is an urgent need for a lens vibration testing device to solve the above problems. Utility Model Content

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.

[0045] This embodiment provides a lens vibration testing device, which can be used for random sampling inspections of lenses during vibration testing. For example... Figure 1 , Figure 2 and Figure 4 As shown, the lens vibration testing device includes a vibration table 1, a support assembly 2, and an image acquisition assembly 3.

[0046] The vibration table 1 is configured to be connected to a vibration device to vibrate under the drive of the vibration device. The vibration device, as a vibration source, is capable of generating vibration; it can be a vibration motor or other machine capable of generating vibration. It is important to emphasize that the vibration generated by the vibration device is periodic and continuous. Taking a vibration motor as an example, the vibration end of the vibration motor is fixedly connected to the vibration table 1, and the connection method includes, but is not limited to, snap-fit ​​or threaded connection.

[0047] Continuing, the support assembly 2 includes a support column 21 and a mounting plate 22. The support column 21 is disposed on the vibration table 1, and the mounting plate 22 is disposed on the support column 21, facing the image to be captured. The image acquisition assembly 3 includes a first chip 31 and a positioning member 32. The mounting plate 22 has a mounting groove 221 on the side facing the image to be captured, and the first chip 31 is embedded in the mounting groove 221. The positioning member 32 is used to press the lens 100 to be tested against the mounting plate 22, and to make the imaging end of the lens 100 to be tested face the first chip 31.

[0048] In other words, the support column 21 transmits the vibration of the vibration table 1 to the mounting plate 22, and also raises the mounting plate 22 so that it is directly aligned with the image to be captured. The positioning element 32 ensures the relative fixation of the positions between the lens 100 under test and the first chip 31, while the height of the mounting plate 22 ensures that the height of the lens 100 under test matches the height of the image to be captured. With this setup, the operator can capture images before, during, and after lens testing without removing the lens 100, thus meeting the requirements of lens vibration testing and ensuring the smooth progress of the test.

[0049] In this embodiment, the lens vibration testing device is specifically placed inside a testing chamber, the side of which has a transparent testing platform window 200. This testing platform window 200 can be made of materials such as glass or transparent acrylic. The image to be captured is placed in front of the testing chamber, directly facing the testing platform window 200. The mounting plate 22 is also directly facing the image to be captured, i.e., the mounting plate 22 is directly facing the testing platform window 200. The distance between the image to be captured and the testing platform window 200 can be adjusted as needed and is not limited here.

[0050] Optionally, such as Figure 1 , Figure 3 and Figure 4As shown, the mounting plate 22 has a dispensing groove 222 on the side of the mounting groove 221. The dispensing groove 222 is connected to the mounting groove 221, and the first chip 31 is fixed to the bottom of the mounting groove 221 with dispensing adhesive, so as to further improve the reliability of the connection between the first chip 31 and the mounting plate 22 and prevent the first chip 31 from coming out of the mounting groove 221 during vibration.

[0051] Alternatively, the mounting plate 22 may also have a clearance groove 223. The clearance groove 223 is located on the side of the mounting groove 221 and is used to avoid the protrusion 101 on the tail plate of the lens 100 under test. By providing the clearance groove 223, interference between the mounting plate 22 and the protrusion 101 on the tail plate of the lens 100 under test can be avoided when the lens 100 under test presses against the mounting plate 22. Inserting the protrusion 101 into the clearance groove 223 allows for a tighter fit between the lens 100 under test and the mounting plate 22.

[0052] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the positioning component 32 includes a first positioning plate 321 and a second positioning plate 322 disposed opposite to each other. The first positioning plate 321 and the second positioning plate 322 are respectively disposed on both sides of the lens 100 to be tested and are detachably connected to the lens 100 to be tested. The first positioning plate 321 and the second positioning plate 322 are respectively connected to the mounting plate 22. Through the first positioning plate 321 and the second positioning plate 322, the lens 100 to be tested can be stably fixed on the mounting plate 22.

[0053] Specifically, the first positioning plate 321 includes a first connecting portion 3211 and a first fixing portion 3212, and the second positioning plate 322 includes a second connecting portion and a second fixing portion. The first connecting portion 3211 and the second connecting portion are respectively connected to opposite sides of the lens 100 to be tested. The first connecting portion 3211 and the second connecting portion are respectively provided with multiple holes for locking with the lens 100 to be tested, and the first connecting portion 3211 and the second connecting portion are respectively connected to the lens 100 to be tested by fasteners. The first fixing portion 3212 and the second fixing portion extend in a direction away from the lens 100 to be tested, and the first fixing portion 3212 and the second fixing portion are respectively connected to both sides of the groove opening of the mounting groove 221. Through holes are respectively opened on the mounting plate 22 at positions corresponding to the first fixing portion 3212 and the second fixing portion, and locking holes are provided on the first fixing portion 3212 and the second fixing portion. The first fixing portion 3212 and the second fixing portion are also locked and fixed to the mounting plate 22 by fasteners. The first positioning plate 321 and the second positioning plate 322 enable a detachable connection between the lens 100 to be tested and the mounting plate 22, which helps to quickly remove the lens after the test is completed.

[0054] More specifically, the first fixing part 3212 is angled to the first connecting part 3211, and the second fixing part is angled to the second connecting part. In this embodiment, the first fixing part 3212 is perpendicular to the first connecting part 3211, and the second fixing part is perpendicular to the second connecting part. Both the first positioning plate 321 and the second positioning plate 322 are L-shaped. This arrangement ensures the stability of the lens 100 under test during positioning and installation, and also facilitates the connection of the first fixing part 3212 and the second fixing part to the mounting plate 22. This simplifies operation and improves testing efficiency.

[0055] In this embodiment, the lens to be tested 100 is first pre-locked to the first connecting part 3211 and the second connecting part; then, the protrusion 101 of the lens to be tested 100 is aligned with the clearance groove 223 on the mounting plate 22 and inserted into the clearance groove 223; next, the mounting plate 22 is locked to the first fixing part 3212 and the second fixing part; finally, the lens to be tested 100 is locked to the first connecting part 3211 and the second connecting part. Through the first positioning plate 321, the second positioning plate 322, and the mounting plate 22, the problem of the tail plate of the lens to be tested 100 lacking a hole for locking to the first chip 31 can be solved, and the lens to be tested 100 can also be stably fixed on the mounting plate 22.

[0056] like Figure 1 , Figure 2 and Figures 6-8 As shown, the support assembly 2 also includes a support plate 23. The support plate 23 is parallel to and spaced apart from the vibration table 1, and support columns 21 connect the support plate 23 and the vibration table 1. Multiple support columns 21 are specifically provided, arranged circumferentially at the bottom of the support plate 23 to ensure the stability of the support. The height of the support column 21 depends on the height of the testing machine window 200 and the locking position of the lens 100 to be tested on the mounting plate 22, ensuring that the lens 100 to be tested is located at the center of the testing machine window 200, meeting the test height requirements; no restrictions are imposed here.

[0057] Specifically, the mounting plate 22 is disposed on the support plate 23 and is set at an angle to the support plate 23. In this embodiment, the mounting plate 22 is set perpendicular to the support plate 23. A limiting groove 231 is formed on the side of the support plate 23 away from the support column 21, and one end of the mounting plate 22 is embedded in the limiting groove 231. A through hole is formed at the bottom of the limiting groove 231, and a threaded hole is formed at the end of the mounting plate 22. After the mounting plate 22 is inserted into the limiting groove 231, it is then locked to the support plate 23 by bolts or other fasteners, further ensuring the reliability of the connection between the mounting plate 22 and the support plate 23.

[0058] More specifically, the support assembly 2 also includes a fixing block 24. The fixing block 24 is disposed at the bottom of the support column 21 and is connected to the vibration table 1. The contact area between the fixing block 24 and the vibration table 1 is larger than the cross-sectional area of ​​the support column 21. By using the fixing block 24, the contact area between the support column 21 and the vibration table 1 can be increased, thereby ensuring the stability of the components above the support column 21 during the vibration process of the vibration table 1.

[0059] In this embodiment, refer to Figure 7 and Figure 8 The bottom surface of the support plate 23 has a first positioning groove 232, and the top surface of the fixing block 24 has a second positioning groove 241. Both ends of the support column 21 are inserted into the first positioning groove 232 and the second positioning groove 241, respectively, and are locked to the bottom of the first positioning groove 232 and the bottom of the second positioning groove 241. Simultaneously, the bottom surface of the fixing block 24 also has a locking clearance groove and holes for locking to the vibration table 1. The locking clearance groove prevents interference between the ends of the fasteners connecting the fixing block 24 and the support column 21 and the vibration table 1 when the fixing block 24 is locked to the vibration table 1, ensuring the reliability of the connection and the tightness of the fit between the fixing block 24 and the vibration table 1.

[0060] Optionally, continue to refer to Figure 1 and Figure 2 The image acquisition component 3 also includes a second chip 33, a third chip 34, and a mounting post 35. The second chip 33 and the third chip 34 are respectively mounted on the side of the mounting plate 22 away from the lens 100 under test via the mounting post 35. Both the first chip 31 and the second chip 33 are electrically connected to the third chip 34. Through the first chip 31, the second chip 33, and the third chip 34, the image captured by the lens 100 under test can be acquired. Specifically, the third chip 34 is a power supply board and is connected to an external power source.

[0061] In this embodiment, the mounting plate 22 has four mounting slots 221. This means the lens vibration testing device can simultaneously perform vibration tests on four lenses 100 to be tested. The four mounting slots 221 are arranged in a rectangular array, divided into two layers along the height direction. The image acquisition component 3 also includes a support plate 36 and a support rod 37. The support plate 36 is connected to the side of the mounting plate 22 facing away from the first chip 31 and is parallel and spaced apart from the support plate 23. The support rod 37 connects the support plate 36 and the support plate 23 to ensure the stability of the support plate 36. Each lens 100 to be tested corresponds to a set of image acquisition components 3, and the corresponding image acquisition components 3 capture images of the lenses to be tested before, during, and after the test.

[0062] Specifically, the second chip 33 and the third chip 34 corresponding to the lower lens 100 under test are respectively connected to the mounting plate 22 and the support plate 23 via mounting posts 35; the second chip 33 and the third chip 34 corresponding to the upper lens 100 under test are respectively connected to the mounting plate 22 and the bracket plate 36 via mounting posts 35.

[0063] Of course, in other embodiments, the number of lenses 100 to be tested that the lens vibration testing device can perform vibration testing on at the same time can be set according to the size of the mounting plate 22, the size of the test machine window 200 and actual needs, and there is no limitation here.

[0064] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
