technical field

The utility model relates to an improved assembly structure of a photographic lens and a mirror base for telecommunication commodities, in particular to an assembly structure which is simple and economical, easy and convenient to assemble and operate, and can make the adjustment of the focal length more rapid, accurate and stable, and extremely An assembly structure of a photographic lens and a mirror base for telecommunication products that conforms to practical applicability, ideality and progress.

Background technique

According to general telecommunication products (such as mobile phones, tablet computers, laptop computers, driving recorders, car monitors, computers, monitors, etc.) the setting and assembly methods of photographic lenses and mirror mounts are roughly As shown in Fig. 1, Fig. 2 and Fig. 3, the lens 10 mainly includes a lens barrel 101, a lens 102, a pressing piece 103 and a filter glass 104, wherein the lens 102, the pressing piece 103 and the filter glass 104 are in order Installed in the lens barrel 101 to form a lens 10; the lens holder 20 is for the lens 10 to be positioned and combined with the photographic IC 40 on the IC carrier 30; wherein, the lens 10 is provided with threads on the lens barrel 101 peripheral surface 1011, the lens base 20 is provided with a screw thread 2011 corresponding to the lens barrel screw thread 1011 at the joint portion 201; accordingly, the lens 10 and the lens base 20 can be combined with each other through the screw fit of the screw threads 1011 and 2011. Moreover, in order to make the lens 10 have a high-resolution image, through the threaded cooperation between the lens barrel thread 1011 and the lens holder thread 2011, the operator can then rotate the lens barrel 101 after the lens holder 20 is placed on the jig (not shown). (Lens 10) moves up and down to achieve the desired effect of adjusting the focal length; then, remove the lens 10 and the mirror holder 20 self-governing tool that has completed the focal length adjustment, and then apply glue to the combined threads 1011 and 2011 to fix it , the assembly of the lens 10 and the mirror base 20 can be completed.

It is undeniable that the above-mentioned lens and mirror mount setup and assembly methods do provide timely use performance and are currently the most commonly used form. After a long period of use, the industry also found that there are still the following shortcomings:

1. Since the lens and the mirror base are provided with a large number of matching threads, the time to complete the assembly by the mutual screwing will inevitably increase, which will waste man-hours and increase costs.

2. Since the photographic lenses and lens mounts used in telecommunications products are relatively small in size, when the lens barrel and the lens mount are respectively molded by injection molding, they are generally made in a multi-cavity method, resulting in the lens barrel of each cavity The dimensions of the mirror base and the mirror base cannot be exactly the same, but different tolerances will inevitably occur; and, since the lens barrel and the mirror base formed by multiple holes are mixed and assembled, the threads of each lens barrel and the thread of the mirror base There are also different tolerances, so the thread gaps of other mixed assemblies will be different. In addition, the implementation of the mutual threading will easily cause uneven tightness, and the focus adjustment will be performed on the subsequent rotation of the lens barrel. The operation causes unsmooth, unstable and inconvenient disadvantages.

3. As mentioned above, due to the non-uniform thread gap between the lens barrels and the lens base of the mixed assembly, the mutual screw settings are often too loose. Therefore, when the focal length adjustment is completed and the entire lens and lens base autonomous After being placed, it will be very easy to cause the focus to run away due to displacement or vibration, which will cause the disadvantage of increasing the defective rate of the finished product after subsequent processing.

4. As mentioned above, due to the non-uniform thread gaps between the lens barrels and lens bases assembled in this hybrid assembly, the mutual thread settings are often too tight. Therefore, the operation of rotating the lens barrel to adjust the focal length will directly increase the difficulty And increased man-hours, and even the risk of affecting the image resolution.

5. As mentioned above, due to the non-uniform thread clearance of the lens barrels and lens bases in this mixed assembly, the tightness of the mutual screwing is often not uniform. After installing on the mirror base, do a torque test to ensure that the tightness of the screw is within the torque specification. However, this process will directly increase the cost and implementation trouble and inconvenience.

That is, utilize the present utility model that above-mentioned constitutes, because the peripheral surface 1012 of this lens barrel 101 and the hole peripheral surface 2021 of mirror base 20 are made as the oblique shape that cooperates, so lens barrel 101 (lens 10) only needs to be easily aligned. The collimation hole 202 of the mirror base 20 is lightly pressed inward, so that it can slide in smoothly and quickly and be tightly combined with the mirror base 20, so as to effectively shorten the assembly time and improve the assembly efficiency (see FIG. 6 ). Moreover, since the inner end surface of the lens barrel 101 and the inner end surface of the sleeve hole 202 of the mirror base 20 are respectively provided with a matching flange 1013 and a helical surface 2022, after the lens barrel 101 is inserted and assembled into the mirror base 20, the protrusion at the inner end The edge 1013 just abuts against the helical surface 2022 of the mirror holder hole 202, and when the lens barrel 101 is rotated, the flange 1013 of the lens barrel 101 can move up and down along the helical surface 2022 of the mirror holder hole 202. , to achieve the effect of quickly adjusting the focus (see Figure 7).

As mentioned above, it is worth mentioning that since the peripheral surface 1012 of the lens barrel 101 and the peripheral surface 2021 of the hole of the mirror base 20 are set as matching inclined surfaces, they can be easily and tightly fitted when assembling each other without causing any problems. If the tolerances of the respective fabrications are too tight or too loose, then when the lens barrel 101 and the lens base 20 of the present invention are produced by injection molding in a multi-cavity manner, the accuracy requirements will not need to be set separately as in the prior art. The method of screw thread is high, thereby not only having the effect of making it simpler and reducing the cost, but also for many mixed-assembled lens barrels 101 and lens holders 20, it is not necessary to perform torque tests in advance, and it has the effect of saving working hours; of course, For the implementation of the focal length adjustment after mutual assembly, in particular, there will be no time-consuming and labor-intensive adjustment due to too tight assembly, increasing the difficulty of adjustment and affecting image resolution, or the situation that the focal length is easy to run away and difficult to control due to too loose assembly.
