TECHNICAL FIELD
[0001] The utility model relates to diaphragm sticking jig technical field, especially to a kind of floating focusing lens P-iris diaphragm assembly diaphragm sticking jig. BACKGROUND
[0002] In order to stop non-imaging light energy, most of the existing floating focusing lens needs to attach the diaphragm sticker of SOMA material on the aperture assembly, but the diaphragm sticker will be skewed during attachment, which will block the normal imaging light in the optical system and cause the whole system to be poorly imaged. The existing jig cannot guarantee the correct position of the diaphragm sticker. SUMMARY
[0003] Therefore, the utility model aims to provide a floating focusing lens P-iris diaphragm assembly diaphragm sticking jig, which can ensure the concentricity of the diaphragm sticker and the whole structure in accordance with the design requirements without affecting the appearance of the structure, and improve the work efficiency and the rejection rate.
[0004] According to one aspect of the utility model, a floating focusing lens P-iris diaphragm assembly diaphragm sticking jig is provided, the jig is a pressing jig, which is composed of a base, a main rod, a slider sleeved on the main rod and a spring. The top of the main rod of the diaphragm jig has a circular table, and the circular table has a first surface. The floating focusing lens P-iris aperture assembly includes a second surface and a third surface perpendicular to the second surface, and the third surface is provided with a light hole. The top of the slider has a fourth surface, and at least one flat surface is provided on the side of the slider.
[0005] When the floating focusing lens P-iris aperture assembly is placed on the slider, the second surface is attached to the flat surface, the third surface is attached to the fourth surface, and the light hole is concentric with the main rod.
[0006] In the above technical solution, the jig structure of the utility model has a base as a basic support component, which plays a key role in fixing other components. The top of the main rod is designed with a circular table structure, and the specific surface of the circular table (defined as the first surface) is used to support and position the P-iris aperture assembly of the floating focusing lens. The slider is sleeved on the main rod and has the ability to slide along the axis of the main rod. The specific surface (defined as the fourth surface) on the top of the slider is tightly attached to the corresponding surface (defined as the third surface) of the floating focusing lens P-iris aperture assembly, and the flat surface on the side of the slider is attached to another specific surface (defined as the second surface) of the aperture assembly, so as to ensure that the lens is accurately and stably fixed in the right position. The spring device is installed between the main rod and the slider, which provides continuous elastic force for the slider, so that it is tightly attached to the lower part of the circular table of the main rod, thereby ensuring the stable installation state of the lens.
[0007] In the process of installing the floating focus lens P-iris aperture assembly to the jig, the operation steps are as follows: first, the diaphragm sticker is taken off with tweezers, and the glue-coated surface is ensured to face upwards, and it is accurately placed on the first surface; second, the aperture assembly is placed on the slider, and the second surface of the aperture assembly is ensured to be closely attached to the planar part of the side surface of the slider, and the third surface is attached to the fourth surface of the top of the slider. At this time, the light hole of the lens should be kept concentric with the main rod. Then, the slider is pressed to slide down along the main rod, so as to make the diaphragm sticker accurately attached to the light hole part. When the slider is released, the spring force will make the slider return to the initial position closely attached to the circular table of the main rod.
[0008] Compared with the traditional method, the structure design of the utility model can significantly enhance the close-fitting tightness and accuracy between the aperture assembly and the jig through the close fitting between the slider and the aperture assembly and the accurate action of the spring force, thereby effectively improving the close-fitting quality of the diaphragm and ensuring that the optical performance of the lens reaches a more optimal state. The slidable nature of the slider on the main rod and the characteristic that the spring force can be appropriately adjusted according to different lens sizes make the jig be able to adapt to aperture assemblies of different sizes within a certain range (i.e. when there is a height difference between the aperture hole of the aperture assembly and the third surface), and have a certain universality. In addition, the press type design is simple to operate, and only needs to place the lens on the slider and then press the slider to complete the attachment operation, thereby significantly improving the work efficiency.
[0009] In some embodiments, the fourth surface is provided with a first limiting part, and when the floating focus lens P-iris aperture assembly is placed on the slider, the first limiting part limits the rotation of the floating focus lens P-iris aperture assembly along the Z-axis direction and the displacement along the Y-axis direction.
[0010] In the above technical solution, the first limiting part is arranged on the fourth surface of the slider and is used for limiting the floating focus lens P-iris aperture assembly. The limiting part can be a protrusion, a groove or other forms of structure, which can cooperate with the corresponding part of the aperture assembly to limit the movement of the aperture assembly. When the aperture assembly is placed on the slider, the first limiting part contacts the corresponding part of the lens. In the process of pressing the slider to attach the diaphragm to the light hole, the first limiting part exerts a restraining force on the aperture assembly to prevent the lens from rotating in the Z-axis direction (usually the direction perpendicular to the installation plane) and to limit the displacement of the lens in the Y-axis direction (usually the direction along the side surface of the slider). In this way, the lens can maintain the correct position and posture during installation, and the inaccurate diaphragm attachment or the decline of imaging quality caused by the rotation or displacement of the aperture assembly can be avoided.
[0011] Compared with the traditional method, the utility model discloses the structure of floating focus lens P-iris aperture assembly, through the limiting effect of first limiting portion to lens, effectively prevent the rotation and displacement of aperture assembly in the installation process, so that aperture assembly can be more stably installed on the fixture, improve the precision and reliability of diaphragm paste. The design of first limiting portion can adjust and optimize the floating focus lens P-iris aperture assembly of different models and sizes, so that the fixture can adapt to a wider range of lens types, improve its versatility and flexibility. The automatic limiting function of limiting portion reduces the need for manual adjustment of the lens during installation, and the operator only needs to place the lens on the slider, and the fixture can automatically complete the positioning and fixing of the lens, improve the work efficiency, reduce the operation difficulty and error rate.
[0012] In some embodiments, when the slider fits the circular truncated cone, the horizontal height of the first surface is lower than the horizontal height of the fourth surface.
[0013] In the above technical solution, the horizontal height of the first surface is lower than the horizontal height of the fourth surface. This design feature is important when installing the floating focus lens P-iris aperture assembly. It can provide more fault tolerance space for the operation process. Specifically, when the diaphragm paste is accurately placed on the first surface, the aperture assembly still has certain adjustment margin and will not be immediately attached to the light hole due to improper position. This layout not only helps to improve the flexibility of installation, but also effectively prevents installation errors or precision decline caused by premature attachment of the aperture assembly during installation. By reasonably setting the horizontal height difference between the first surface and the fourth surface, the fixture of the utility model can improve the convenience and fault tolerance of operation while ensuring the installation precision, thereby further improving the overall installation quality and efficiency.
[0014] In some embodiments, the main rod of the diaphragm fixture is connected to the base by a thread.
[0015] In the above technical solution, the main rod is connected to the base by a thread. This connection method allows the main rod to be firmly fixed on the base, and can also be easily disassembled and adjusted. In addition, adjusting the thread to control the spring force can ensure that the aperture assembly always maintains a stable position and posture when attaching the diaphragm paste, reducing the loosening, displacement or shaking of the aperture assembly caused by insufficient or excessive spring force, thereby improving the precision of diaphragm paste.
[0016] In some embodiments, the diameter of the circular truncated cone is greater than or equal to the diameter of the diaphragm paste.
[0017] In the above technical solution, the diameter of the circular table is designed to match the diameter of the iris diaphragm, which plays a key role in the installation process. When the iris diaphragm is placed on the circular table, it can achieve precise alignment with the lens aperture. Since the circular table itself maintains strict concentricity with the main rod, the iris diaphragm can naturally maintain coaxiality with the main rod when placed on the circular table. This coaxiality ensures that the center of the iris diaphragm is precisely aligned with the optical axis of the lens, and in addition, this design not only improves the accuracy of installation, but also reduces the possibility of iris diaphragm deviation or installation errors caused by improper alignment.
[0018] In some embodiments, a second limiting portion is arranged at the center of the first surface.
[0019] In the above technical solution, the second limiting portion provides a precise positioning reference for the installation of the iris diaphragm. When the iris diaphragm is placed on the circular table, its center position is accurately limited by the second limiting portion, thereby ensuring that the center of the iris diaphragm is precisely aligned with the optical axis of the aperture assembly. This precise alignment mechanism can effectively prevent the iris diaphragm from deviating or tilting during installation, significantly improving the accuracy and reliability of installation. In addition, the design of the second limiting portion makes the installation process of the iris diaphragm simple and intuitive. When placing, the operator only needs to align the iris diaphragm with the limiting portion and place it, which can quickly complete the positioning and installation operation. This process does not require complex adjustment and calibration work, greatly improving production efficiency, while reducing the difficulty of operation and the error rate.

[0028] One of the embodiments
[0029] A kind of floating focusing lens P-iris diaphragm assembly diaphragm sticking jig, please refer to Figure 1 , in the figure 1 is floating focusing lens P-iris diaphragm assembly, 3 is diaphragm sticking. The jig 2 is presser jig, is composed of base 21, main rod 22, slider 23 and spring 24 of being set in main rod 22;The main rod 22 top has a circular table 221, the circular table has a first surface a;The floating focusing lens P-iris diaphragm assembly 1 includes a second surface b, the third surface c vertical with second surface b, the third surface c is provided with a light hole 11;The slider top has fourth surface d, and at least one plane e is provided in side face;
[0030] Please refer to Figure 2 , when the floating focusing lens P-iris diaphragm assembly 1 is placed in the slider 23, the second surface b is attached with the plane e, the third surface c is attached with the fourth surface d, and the light hole 11 is concentric with the main rod 22.
[0031] In the embodiment, the jig structure related by the utility model, its base as the basic support component, undertakes the key role of fixing other components. The main rod top is designed with the circular table structure, the specific surface of the circular table (defined as the first surface) is used for supporting and positioning operation to the P-iris diaphragm assembly of floating focusing lens. The slider is set on the main rod and has the ability of sliding along the main rod axial direction. The specific surface (defined as the fourth surface) of the slider top is tightly combined with the corresponding surface (defined as the third surface) of the P-iris diaphragm assembly of floating focusing lens, and the plane part of the slider side is combined with another specific surface (defined as the second surface) of the diaphragm assembly, so as to ensure that the lens is accurately and stably fixed in the appropriate position. The spring device is installed between the main rod and the slider, provides the continuous elastic force for the slider, makes it tightly combined below the main rod circular table, so as to ensure the stable installation state of the lens.
[0032] In the process of installing the P-iris diaphragm assembly of floating focusing lens to the jig, the operation steps are as follows: first, the diaphragm sticker is taken off by using the tweezers, and the glue coating surface is ensured to face upwards, and it is accurately placed on the first surface; second, the diaphragm assembly is placed on the slider, and the second surface of the diaphragm assembly is tightly combined with the plane part of the slider side, and the third surface is combined with the fourth surface of the slider top. At this time, the light hole of the lens should be kept concentric with the main rod. Then, the slider is pressed to slide downward along the main rod, so as to make the diaphragm sticker accurately adhere to the light hole part. When the slider is released, the elastic force of the spring will make the slider return to the initial position tightly combined with the main rod circular table.
[0033] Compared with the traditional method, the structure design of the utility model can significantly enhance the close tightness and accuracy between the diaphragm assembly and the jig through the close cooperation between the slider and the diaphragm assembly and the accurate action of the spring elastic force, thereby effectively improving the adhesion quality of the diaphragm and ensuring that the optical performance of the lens reaches a better state. The slidable nature of the slider on the main rod and the characteristics of the spring elastic force that can be adjusted according to different lens sizes make the jig can adapt to diaphragm assemblies of different sizes within a certain range (i.e. when there is a height difference between the diaphragm hole of the diaphragm assembly and the third surface), and has a certain universality. In addition, the pressing type design is simple and convenient to operate, only needs to place the lens on the slider, and then press the slider to complete the adhesion operation, thereby significantly improving the work efficiency.
[0034] In the embodiment, please refer to Figure 3The fourth surface d is provided with a first limiting part 231, which limits the rotation of the floating focus lens P-iris aperture assembly 1 along the Z-axis direction and the displacement of the floating focus lens P-iris aperture assembly 1 along the Y-axis direction when the floating focus lens P-iris aperture assembly 1 is placed on the sliding block 23. The first limiting part is arranged on the fourth surface of the sliding block and is used for limiting the floating focus lens P-iris aperture assembly. The limiting part can be a protrusion, a groove or other forms of structures, which can cooperate with the corresponding part of the aperture assembly to limit the movement of the aperture assembly. When the aperture assembly is placed on the sliding block, the first limiting part is in contact with the corresponding part of the lens. In the process of pressing the sliding block to make the aperture adhere to the light hole, the first limiting part applies a constraint force to the aperture assembly to prevent the lens from rotating in the Z-axis direction (usually the direction perpendicular to the mounting plane) and limit the displacement of the lens in the Y-axis direction (usually the direction along the side of the sliding block). In this way, the lens can maintain the correct position and posture during installation, avoiding inaccurate diaphragm fitting or image quality degradation caused by rotation or displacement of the aperture assembly.
[0035] Compared with the traditional method, the utility model considers the structure of the floating focus lens P-iris aperture assembly, effectively prevents the rotation and displacement of the aperture assembly during installation through the limiting effect of the first limiting part on the lens, so that the aperture assembly can be more stably installed on the jig, and the precision and reliability of the diaphragm fitting are improved. The design of the first limiting part can be adjusted and optimized according to different models and sizes of the floating focus lens P-iris aperture assembly, so that the jig can adapt to a wider range of lens types, improve its versatility and flexibility. The automatic limiting function of the limiting part reduces the need for manual adjustment of the lens during installation, and the operator only needs to place the lens on the sliding block, and the jig can automatically complete the positioning and fixing of the lens, improving the work efficiency, reducing the operation difficulty and error rate.
[0036] In the embodiment, please refer to Figure 4 When the sliding block is fitted with the circular table, the horizontal height H of the first surface a is lower than the horizontal height h of the fourth surface d.
[0037] In the above technical solution, the horizontal height of the first surface is lower than the horizontal height of the fourth surface. This design feature is of great significance when installing the floating focus lens P-iris aperture assembly. It provides more fault tolerance space for the operation process. Specifically, when the diaphragm sticker is accurately placed on the first surface, the aperture assembly still has a certain adjustment margin and will not be immediately attached to the light hole due to improper positioning. This layout not only helps to improve the flexibility of installation, but also effectively prevents installation errors or precision decline caused by the aperture assembly attaching too early during installation. By reasonably setting the horizontal height difference between the first surface and the fourth surface, the jig of the present application can improve the convenience and fault tolerance of the operation while ensuring the installation precision, thereby further improving the overall installation quality and efficiency.
[0038] In the present embodiment, the main rod 22 is connected to the base 21 by screwing. The main rod is connected to the base by screwing, which makes the main rod firmly fixed on the base, and also can be conveniently disassembled and adjusted. In addition, reasonable adjustment of the screw thread to control the elastic force can ensure that the aperture assembly always maintains a stable position and posture when attaching the diaphragm sticker, reducing the aperture assembly loosening, displacement or shaking caused by insufficient or excessive elastic force, thereby improving the precision of the diaphragm sticker.
[0039] In the present embodiment, the circular table 221 has a diameter greater than or equal to the diameter of the diaphragm sticker 3. The diameter of the circular table is designed to match the diameter of the diaphragm sticker, which plays a key role in the installation process. When the diaphragm sticker is placed on the circular table, it can be accurately aligned with the lens light hole. Since the circular table itself maintains strict concentricity with the main rod, the diaphragm sticker can naturally maintain coaxial state with the main rod when placed on the circular table. This coaxiality ensures that the center of the diaphragm sticker is accurately aligned with the optical axis of the lens, and in addition, this design not only improves the installation precision, but also reduces the possibility of diaphragm sticker deviation or installation error caused by improper alignment.
[0040] In the present embodiment, please refer to Figure 5 , the first surface a is provided with a second limiting part 222 at the center. The second limiting part provides an accurate positioning reference for the installation of the diaphragm sticker. When the diaphragm sticker is placed on the circular table, its center position will be accurately limited by the second limiting part, thereby ensuring that the center of the diaphragm sticker is accurately aligned with the optical axis of the aperture assembly. This precise alignment mechanism can effectively prevent the diaphragm sticker from deviating or tilting during installation, significantly improving the installation precision and reliability. In addition, the design of the second limiting part makes the installation process of the diaphragm sticker simple and intuitive. The operator only needs to align the diaphragm sticker with the limiting part and place it to quickly complete the positioning and installation operation. This process does not require complex adjustment and calibration work, greatly improving production efficiency, while reducing the difficulty of operation and the error rate.
[0041] The working principle of the embodiment is as follows:
[0042] Place the base 21 on a horizontal table top, with the large-diameter hole in the slider 23 facing upwards, and the threaded end of the main rod 22 inserted into the slider 23 with the threaded end facing downwards; insert the spring 24 into the main rod 22, and finally couple the threaded bottom of the main rod 22 with the base 21. When in use, remove the diaphragm sticker with tweezers, with the glue side facing upwards, and place it on the top of the main rod 22, with the inner diameters matching each other; remove the P-iris aperture assembly of the floating focusing lens, and place it with the side to be pasted facing downwards in the four-edged slot of the slider 23, with the inner side surface b of the aperture assembly tightly pasted with the contact surface a of the slider, and then press it downwards. The existing diaphragm pasting jig uses a plug-in form, and after pasting, the P-iris needs to be pulled out from the inside of the jig, which often causes the diaphragm sticker to be pulled out and wrinkled, and it is difficult for the sticker to be pasted in place manually during the pasting process, which wastes a large amount of sticker during the operation process, and the P-iris is easily scratched and scrapped when pulled out. The present jig is designed into a pressing type through structural cooperation, which improves the mobility of the entire jig, and the spring at the bottom can reduce the buffering protection of the P-iris, and reduce the influence on the performance. On the premise that the performance and appearance are not affected, the production efficiency and operation convenience are greatly improved. The P-iris is placed on the slider, and through the cooperation of the structure of the P-iris itself and the limiting of the slider, the diaphragm sticker is pasted on the P-iris through the downward pressing mode. Because of the buffering of the bottom spring, the flatness precision control of the jig and the contact surface of the P-iris achieve the best cooperation effect, which improves the imaging rate of the lens and improves the production efficiency and reduces the risk of product scrapping.
[0043] The above only describes some embodiments of the present application, and does not limit the protection scope of the present application, and any equivalent device or equivalent process conversion, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
