Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens technology, and in particular to a lens component fit margin detection device. Background Technology
[0002] In the field of optical lenses, the fit margin between the lens components (such as lens elements or spacers) and the lens frame has a crucial impact on the lens's resolving power. Therefore, checking the fit margin between the lens components and the lens frame is an important step in the lens assembly process.
[0003] In existing technologies, the fit margin between components and frames is generally judged by human experience. That is, after the component to be tested is installed in the corresponding position of the frame, an experienced assembler pushes the component out and judges the fit margin by feel. This method relies too much on experience and lacks quantitative data to explain it, which leads to differences in the test results. Utility Model Content
[0004] The purpose of this invention is to provide a lens component fit margin detection device to replace manual margin detection of lens components, thereby improving detection reliability.
[0005] To achieve this objective, the present invention adopts the following technical solution:

[0008] The mounting base is fixedly installed on the force-bearing platform, and the mounting base is provided with a receiving cavity and a mounting hole communicating with the receiving cavity;
[0009] A support fixture is disposed within the mounting hole, and the support fixture is provided with a through hole. The lens frame is disposed within the through hole. The thruster can drive the push rod to move to push the part to be tested within the lens frame out of the lens frame into the receiving cavity. The detection element can detect the thrust of the push rod.
[0010] As an alternative, a limiting step is provided inside the through hole, and the mirror frame is supported on the limiting step.

The plug-in part is disposed in the mounting hole, and the limiting part abuts against and limits the mounting base.
[0012] The through hole includes a first section disposed on the bearing portion, a second section disposed on the limiting portion, and a third section disposed on the insertion portion. The diameter of the second section is smaller than the diameter of the first section, so that the end face of the limiting portion facing the bearing portion forms the limiting step.
[0013] As an alternative, the diameter of the third segment is larger than the diameter of the second segment.
[0014] As an optional solution, the mounting base includes a mounting plate and a boss disposed on the mounting plate. The mounting plate is connected to the force-bearing platform. The boss is provided with the receiving cavity. The end of the boss facing away from the mounting plate is provided with the mounting hole. The limiting part abuts against the end of the boss facing away from the mounting plate. The side wall of the boss is provided with an opening communicating with the receiving cavity.

[0018] As an alternative, the gasket fixture includes a first gasket fixture;
[0019] When the part to be tested is a spacer, the spacer is disposed in the frame and abuts against the first gasket fixture. The push rod drives the first gasket fixture to move so as to push the spacer into the receiving cavity.
[0020] As an optional solution, the gasket fixture further includes a second gasket fixture, which is provided with a central clearance hole;
[0021] When the component to be tested is a lens, the lens is placed inside the lens frame and abuts against the second gasket fixture. The push rod passes through the central clearance hole and abuts against the lens to push the lens into the receiving cavity.
[0022] The beneficial effects of this utility model are:
[0023] This utility model provides a lens component fit margin detection device. The lens frame is placed in the through hole of the support fixture, and the support fixture is placed in the mounting hole.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0040] This utility model embodiment provides a lens component fit margin detection device. The lens includes a lens frame 100 and components disposed within the lens frame 100. Multiple components within the lens can be installed one by one at corresponding positions within the lens frame 100. The lens component fit margin detection device can detect the fit margin between each component disposed within the lens frame 100 and the lens frame 100.
[0041] like Figures 1-5As shown, the lens component fit margin detection device includes a thrust machine, a mounting base 2, and a support fixture 3. The thrust machine includes a force-bearing platform, a detection element, and a push rod 1. The push rod 1 is located at the drive end of the thrust machine, and the thrust machine can drive the push rod 1 to move towards the force-bearing platform. The detection element is located between the drive end of the thrust machine and the push rod 1. The mounting base 2 is fixedly mounted on the force-bearing platform and includes a receiving cavity 221 and a mounting hole 222 communicating with the receiving cavity 221. The support fixture 3 is provided in the mounting hole 222 and has a through hole 34. The mirror frame 100 is provided in the through hole 34. The thruster can drive the push rod 1 to move toward the force platform to push the part to be tested out of the mirror frame 100. The part to be tested falls into the receiving cavity 221 through the through hole 34. During this process, the test piece can detect the thrust of the push rod 1 pushing the part to be tested.
[0042] The lens component, in conjunction with the margin detection device, places the lens frame 100 into the through hole 34 of the support fixture 3, and then places the support fixture 3 into the mounting hole 222. The push rod 1 driven by the pusher pushes the component to be tested out of the lens frame 100 and into the receiving cavity 221 for collection. During this process, the detection device can detect the pushing force of the push rod 1, thus obtaining quantitative margin data. This replaces manual testing of the fit margin of the lens component, avoids reliance on experience, improves the reliability of the data, and is easy to operate.
[0043] Optionally, the sensing element can be a force sensor.
[0044] like Figure 2 As shown, when the frame 100 is disposed in the through hole 34, in order to prevent the frame 100 from shifting when the push rod 1 pushes the part to be tested, a limiting step 321 is optionally provided in the through hole. The frame 100 is disposed in the through hole 34 and supported on the limiting step 321. When the push rod 1 pushes the part to be tested, the frame 100 does not move due to the support of the limiting step 321, and the part to be tested is pushed out of the frame 100.
[0045] Specifically, the support fixture 3 includes a limiting part 32, an insertion part 33 disposed at one end of the limiting part 32 facing the mounting base 2, and a support part 31 disposed at one end of the limiting part 32 facing the push rod 1. The insertion part 33 can be inserted into the mounting hole 222, and the limiting part 32 abuts against the mounting base 2 to limit the movement. The through hole 34 includes a first section 341 disposed at the support part 31, a second section 342 disposed at the limiting part 32, and a third section 343 disposed at the insertion part 33. The diameter of the second section 342 of the through hole 34 is smaller than the diameter of the first section 341 of the through hole 34, so that the end face of the limiting part 32 facing the support part 31 forms a limiting step 321. This structure allows the frame 100 to be disposed in the first section 341 and to abut against the end face of the limiting part 32 (i.e., the limiting step 321), which is convenient for design, processing, and manufacturing.
[0046] In order to make the part to be inspected pass through the through hole 34 more smoothly, the diameter of the third segment 343 of the through hole 34 is larger than the diameter of the second segment 342 of the through hole 34, so that the part to be inspected can pass through the through hole 34 without any jamming.
[0047] Optionally, the side wall of the support part 31 is provided with a first threaded hole 311 that communicates with the first section 341 of the through hole 34. A first screw is provided in the first threaded hole 311. The first screw is screwed into the first threaded hole 311 and presses against the frame 100 to prevent the frame 100 from shaking.
[0048] Specifically, such as Figure 3 and combined Figure 2 As shown, the mounting base 2 includes a mounting plate 21 and a boss 22 disposed on the mounting plate 21. The mounting plate 21 is connected to the force-bearing platform. The boss 22 is provided with a receiving cavity 221, and a mounting hole 222 is provided at the end of the boss 22 away from the mounting plate 21. The insertion part 33 is inserted into the mounting hole 222, and the limiting part 32 is limited at the end of the boss 22 away from the mounting plate 21. The side wall of the boss 22 is provided with an opening communicating with the receiving cavity 221. The part to be tested that has fallen into the receiving cavity 221 can be taken out through the opening.
[0049] Optionally, the lens component tolerance detection device also includes a receiving box, which can slide into or out of the receiving cavity 221 through the opening. When testing, the receiving box is located in the receiving cavity 221. When the component to be tested falls, it can fall into the receiving box. Then, by sliding out of the receiving box, the component to be tested can be taken out, making the operation more convenient.
[0050] To make the mounting fixture 3 more stable, the boss 22 is provided with an extension 223 at one end away from the mounting plate 21, and the mounting hole 222 is provided through the extension 223. This structure can increase the contact area between the insertion part 33 and the mounting hole 222, thereby improving the installation stability.
[0051] Optionally, the extension 223 is provided with a second threaded hole 2231 communicating with the mounting hole 222. A second screw is provided in the second threaded hole 2231. The second screw is screwed into the second threaded hole 2231 and can tighten the insertion part 33, so that the support fixture 3 is installed more stably and avoids shaking.
[0052] In this embodiment, the mounting plate 21 is connected to the force-bearing platform by a third screw, and the mounting plate 21 is provided with an elongated hole 211 extending along the sliding direction of the receiving box. The third screw passes through the elongated hole 211 and is connected to the force-bearing platform. This structure allows the mounting base 2 to move and adjust its position along the sliding direction of the receiving box.
[0053] Optionally, such as Figures 4-5 As shown, the lens component fit margin detection device also includes a shim fixture, which is disposed within the lens frame 100 and can support the component to be tested. The shim fixture can be designed with different height specifications according to the components located at different positions within the lens frame 100. That is, the shim fixture can replace other components located below the component to be tested within the lens frame 100 to support the component to be tested, thereby ensuring that the installation of the component to be tested matches the actual assembly.
[0054] Optionally, there are two types of gasket fixtures, including a first gasket fixture 4 and a second gasket fixture 5, wherein the second gasket fixture 5 is provided with a central clearance hole 51.
[0055] For example, when the component to be inspected is spacer 200, spacer 200 is positioned at a corresponding location within the frame 100 and abuts against the first shim fixture 4. The first shim fixture 4 is a solid structure. When the push rod 1 pushes the spacer 200 to fall, it abuts against the first shim fixture 4 to drive the first shim fixture 4 to move, thereby causing the first shim fixture 4 to push the spacer 200 to move. It is understood that the first shim fixture 4, used to push the spacer 200 to move, has a gap with the frame 100, which does not affect the pushing force of the push rod 1.
[0056] For example, when the part to be tested is a lens 300, the lens 300 is positioned in the corresponding position within the frame 100 and abuts against the second gasket fixture 5. The push rod 1 can pass through the central clearance hole 51 to abut against the lens 300, so as to push the lens 300 into the receiving cavity 221.
[0057] Understandably, when testing the lens 300 located at the bottom of the frame 100, there is no need to set up the second shim fixture 5.
[0058] 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.
