Description

Technical Field

[0001] This utility model relates to the field of optical lens assembly technology, specifically a lens fitting and adjustment tool. Background Technology

[0002] Optical-mechanical modules are integrated components used in electronic glasses or other smart wearable devices. They mainly include lens assemblies with multiple lens groups, an integrated motherboard, and an image acquisition lens. In the current assembly process, it is necessary to ensure that the acquisition axis of the lens assembly and the acquisition lens are aligned, that is, the central lens aperture of the lens must be on a straight line. Otherwise, problems such as image shadows, dark images, or blurry images will occur. However, manual fine-tuning between multiple lens groups is very difficult. Even with a general positioning structure, slight touches can easily produce huge image errors. Therefore, assembly is very difficult and inefficient. There is currently a lack of such targeted assembly fixtures on the market, and existing fixtures have poor compatibility.

[0003] Based on this, the present invention designs a fitting and debugging tool to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fitting and debugging tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fitting and debugging fixture includes a debugging platform, a detection electronic lens for testing an optical module, and a module mounting bracket for mounting the optical module. The detection electronic lens is mounted on the front side of the panel of the debugging platform via a horizontal sliding mechanism. The detection electronic lens is mounted on the horizontal sliding mechanism via a fine-tuning mechanism for adjusting the height and lateral displacement of the detection electronic lens. The module mounting bracket is mounted directly behind the detection electronic lens in the shooting direction via a vertical sliding mechanism. The module mounting bracket is provided with a positioning mechanism for positioning and mounting the optical module. A lens adjustment port is provided on the rear panel of the module mounting bracket corresponding to the position of the acquisition lens of the optical module. Multiple adjustment rods are arranged around the lens adjustment port. When the optical module is mounted on the module mounting bracket via the positioning mechanism, the acquisition lens extends into the lens adjustment port, and the multiple adjustment rods are rotated, causing the adjustment rods to press inward against the outer wall of the acquisition lens.

[0007] As a further embodiment of this utility model: the longitudinal movement mechanism includes two module slide rails that are fixed horizontally and vertically on the surface of the debugging platform, and the bottom left and right sides of the module mounting bracket are respectively fixed with sliders for sliding and locking on the corresponding module slide rails.

[0008] As a further embodiment of this utility model: the transverse movement mechanism includes two detection slide rails that are fixed horizontally and parallel to each other on the surface of the debugging platform. The detection slide rails are arranged in front of the module slide rails. The adjustment seat is slidably mounted above the two detection slide rails. The detection electronic lens and the fine-tuning mechanism are installed above the adjustment seat.

[0009] As a further embodiment of this utility model: the positioning mechanism includes a plurality of positioning pins provided on the front panel of the module mounting bracket, the optical module having pin holes corresponding to the positioning pins, and pressure plates for abutting the front panel of the optical module being rotatably provided on the left and right sides of the front panel of the module mounting bracket.

[0010] As a further embodiment of this utility model: the side of the panel that contacts the optical module with the pressure plate is provided as a deformable flexible surface layer.

[0011] As a further embodiment of this utility model: the fine-tuning mechanism includes a lifting adjustment component and a translation adjustment component. The lifting adjustment component is fixed to the top of the adjustment seat, the translation adjustment component is installed at the lifting end of the lifting adjustment component, and the lens of the detection electronic lens is installed at the displacement end of the translation adjustment component with the lens facing backward.

[0012] As a further embodiment of this invention: a horizontal component is mounted on the surface of the test bench.

[0013] As a further embodiment of this utility model: the detection electronic lens is connected to a display unit via a data cable, and a background image board is erected on the rear side of the debugging platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The debugging platform set in this utility model can flexibly adjust the two lens components on the optical module. The adjustment process only requires rotating the adjustment lever and cooperating with the detection electronic lens to realize whether the collimator axis of the lens component and the acquisition lens is aligned. The assembly difficulty is greatly reduced, the assembly and debugging efficiency is greatly improved, and the consistency of debugging quality is guaranteed.

[0016] 2. The detection electronic lens of this utility model can be connected to an external display device for intuitive operation, and the background image board can standardize the detection process, ensure the consistency of the detection images, and improve the judgment effect;

[0017] 3. The module mounting bracket provided by this utility model can stably support and limit the optical module. The multi-angle adjustment lever can realize the fine adjustment of the acquisition lens, which facilitates the eye-close adjustment process and is simple and easy to operate.

Detailed Implementation

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] Example 1

[0028] A fitting and debugging fixture includes a debugging platform 1, a detection electronic lens 4 for detecting an optical module 2, and a module mounting bracket 12 for mounting the optical module 2. The detection electronic lens 4 is mounted on the front side of the panel of the debugging platform 1 via a horizontal movement mechanism. The detection electronic lens 4 is mounted on the horizontal movement mechanism via a fine-tuning mechanism for adjusting the height and left and right displacement of the detection electronic lens 4. The module mounting bracket 12 is mounted directly behind the detection electronic lens 4 in the shooting direction via a vertical movement mechanism. The module mounting bracket 12 is provided with a positioning mechanism for positioning and mounting the optical module 2. The rear panel of the module mounting bracket 12 has a lens adjustment port 13 corresponding to the position of the acquisition lens 22 of the optical module 2. Multiple adjustment rods 14 are arranged around the lens adjustment port 13. When the optical module 2 is mounted on the module mounting bracket 12 via the positioning mechanism, the acquisition lens 22 extends into the lens adjustment port 13. Rotating the multiple adjustment rods 14 causes the adjustment rods 14 to press inward against the outer wall of the acquisition lens 22.

[0029] During operation, the main test for optical module 2 is whether the centerlines of lens assembly 20 and the corresponding acquisition lens 22 are aligned. Although both lens assembly 20 and acquisition lens 22 are installed and positioned using mounting holes during production assembly, inconsistent tightening of multiple bolt holes can prevent the overall alignment, meaning the centerlines are not aligned. This results in images captured by the detection lens 4 from optical module 2 exhibiting either localized shadows or insufficient brightness. Here, with lens assembly 20 stationary as a reference, only the position of acquisition lens 22 is adjusted. When the image captured by detection lens 4... When the preset value is met, the angle of the acquisition lens 22 is standard. Tightening the acquisition lens 22 at this point ensures a proper fit. The electronic lens 4 is connected to a display device, typically part of a set, which will not be elaborated here. Specifically, the optical module 2 is first mounted on the module mounting bracket 12 using a positioning mechanism. Then, the horizontal and vertical movement mechanisms are adjusted to bring the detection electronic lens 4 closer to one of the lens components 20 of the optical module 2. A fine-tuning mechanism ensures that the image captured by the detection electronic lens 4 is aligned with the lens component 20. Align the lens and then rotate the adjustment lever 14 on the rear side of the corresponding lens assembly 20. When the image captured by the detection lens 4 reaches its clearest state, use the curing adhesive to fix the acquisition lens 22 onto the surface of the lens mounting plate 21, keeping its position unchanged. It should be noted that the acquisition lens 22 is screwed onto the surface of the lens mounting plate 21 through the screw hole 23. In actual adjustment, a screw is threaded through the acquisition lens 22, but at this time the screw is in the untightened state. The actual micro-adjustment size of the acquisition lens 22 is very small, which is smaller than the tightness allowance of the screw and the screw hole 23. Therefore, the screw in the screw hole does not affect the adjustment. Furthermore, the adjusting lever 14 at this time will interfere with tightening the screw to some extent. Therefore, a pre-fixing auxiliary fixation is performed using curing adhesive. After the adhesive has cured, multiple adjusting levers 14 are pulled outwards, and then the corresponding screws in the screw holes 23 are tightened. Observe whether the image of the electronic lens 4 still remains bright and clear. If so, the assembly and debugging are completed. Otherwise, fine-tuning and applying adhesive again are performed. Of course, the position of the adjusting lever 14 can be finely adjusted to offset the screw holes 23 from the adjusting lever 14, thus omitting the adhesive application step. The specific adjustment can be made according to the actual acquisition lens 22 specifications and the position of its screw holes 23, which will not be elaborated here.

[0030] The longitudinal movement mechanism includes two module slide rails 10 that are fixed horizontally and vertically on the surface of the debugging platform 1. The bottom left and right sides of the module mounting bracket 12 are respectively fixed with sliders for sliding and locking on the corresponding module slide rails 10.

[0031] The transverse mechanism includes two detection slide rails 11 that are fixed horizontally and parallel to each other on the surface of the debugging table 1. The detection slide rails 11 are located on the front side of the module slide rail 10. The adjustment seat 3 is slidably mounted on the two detection slide rails 11. The detection electronic lens 4 and the fine-tuning mechanism are installed on the adjustment seat 3.

[0032] During operation, the module mounting bracket 12 adjusts its distance from the detection electronic lens 4 by sliding on the module slide rail 10. The detection electronic lens 4 mainly uses the detection slide rail 11 to meet the positional requirements of the lens components 20 at different positions on the optical module 2 during calibration.

[0033] The positioning mechanism includes multiple positioning pins 15 provided on the front panel of the module mounting bracket 12, and pin holes provided on the optical module 2 corresponding to the positioning pins 15. Pressure plates 16 for abutting against the front panel of the optical module 2 are rotatably provided on the left and right sides of the front panel of the module mounting bracket 12.

[0034] During operation, first align the pin holes on the optical module 2 with the positioning pins 15 for installation. The entire optical module 2 will then be vertically mounted on the front panel of the module mounting bracket 12, with the lens assembly 20 of the optical module 2 facing the lens of the detection electronic lens 4. Then, rotate the pressure plates 16 on both sides to the front panel position of the optical module 2 to hold it in place, thereby ensuring that the module mounting bracket 12 will not shift or shake.

[0035] The panel side of the pressure plate 16 that contacts the optical module 2 is provided as a deformable flexible surface layer;

[0036] During operation, in order to prevent the pressure plate 16 from scratching the surface of the optical module 2 and to prevent the optical module 2 from shaking, the pressure plate 16 adopts a flexible surface layer, such as a soft rubber layer. During the process of rotating to the front panel of the optical module 2, the soft rubber layer will be squeezed and deformed, pressing the optical module 2 tightly backward, so as to ensure that the overall position of the optical module 2 will not shake or shift when adjusting the adjustment knob 14.

[0037] The fine-tuning mechanism includes a lifting adjustment component 30 and a translation adjustment component 31. The lifting adjustment component 30 is fixed to the top of the adjustment seat 3, the translation adjustment component 31 is installed at the lifting end of the lifting adjustment component 30, and the rearward-facing lens of the detection electronic lens 4 is installed at the displacement end of the translation adjustment component 31.

[0038] During operation, the lifting adjustment component 30 and the translation adjustment component 31 are existing adjustment modules. There are many corresponding modules on the market, so the specific structure will not be described in detail here. It is sufficient to meet its fine-tuning function.

[0039] Example 2

[0040] The difference between this implementation and Example 1 is as follows:

[0041] The surface of the test bench 1 is equipped with a horizontal component 17;

[0042] During operation, the leveling component 17 is mainly used to ensure the levelness of the test bench 1. The leveling component 17 can be a level or similar instrument to reduce other interference factors during assembly.

[0043] The detection electronic lens 4 is connected to a display unit via a data cable, and a background image board is erected on the rear side of the debugging platform 1.

[0044] During operation, the main focus here is on standardized testing procedures. The background image board ensures the consistency of images acquired by the acquisition lens 22. By using the preset standard image background, it is possible to more quickly determine whether the images acquired by the testing electronic lens 4 meet the standards.
