[0033] This embodiment provides a lens barrel, which has an engraving portion outside the hollow portion. While ensuring the stable molding of the lens barrel, it can provide engraving space and improve the aesthetics of the lens barrel, and can also reduce the amount of glue used and improve the efficiency and quality of glue dispensing.
[0034] Specifically, Figure 1-Figure 3 As shown, the lens barrel 100 includes a lens barrel body 110, and the lens barrel body 110 is provided with a hollowing portion 111 and a lettering portion 112. The hollowing portion 111 is provided to perform a hollowing process on the lens barrel body 110, which is convenient for injection molding of the lens barrel 100. The lettering portion 112 is provided to provide a position for lettering, avoid lettering on the front end surface of the lens barrel 100, and improve the aesthetics of the lens barrel 100.
[0035] The hollowed-out portion 111 includes an annular hollowed-out groove 1111 and a plurality of reinforcing ribs 1112. The annular hollowed-out groove 1111 is provided on the outer peripheral wall of the lens barrel body 110, and the plurality of reinforcing ribs 1112 are provided in the annular hollowed-out groove 1111. By providing a plurality of reinforcing ribs 1112 in the annular hollowed-out groove 1111, the molding stability and structural strength of the lens barrel body 110 can be improved, thereby improving the concentricity and durability of the lens barrel 100.
[0036] The engraving portion 112 covers a portion of the annular hollow groove 1111. With this arrangement, on the one hand, the engraving portion 112 can provide a position for engraving, so that there is no need to engrave the words on the front end surface of the lens barrel 100, thereby improving the aesthetics of the lens barrel 100; on the other hand, the arrangement of the engraving portion 112 will not affect the hollowing process of the lens barrel 100; on the other hand, when the glue point of the lens barrel 100 is located at the position of the engraving portion 112, the amount of glue used is less than the amount used at the annular hollow groove 1111, thereby reducing the risk of the glue not drying, improving the glue dispensing quality, and the engraving portion 112 is convenient for glue dispensing, thereby improving the glue dispensing efficiency.
[0037] Optionally, the hollow portion 111 is an arc-shaped plate-shaped structure, and covers a small section of the notch of the annular hollow groove 1111 .
[0038] Optionally, in this embodiment, two engraving parts 112 are provided, and the two engraving parts 112 are symmetrically arranged on both sides of the axis of the lens barrel body 110. The two engraving parts 112 are symmetrically arranged, which can provide multiple engraving positions to meet various engraving requirements and improve the aesthetics of the lens barrel 100.
[0039] It is worth noting that the engraving portion 112 is generally used for engraving a two-dimensional code.
[0040] Optionally, in this embodiment, the length of the engraving portion 112 along the axial direction of the lens barrel body 110 is 3 cm-4 cm, and the length of the engraving portion 112 along the circumferential direction of the lens barrel body 110 is 1.5 cm-2 cm. The engraving portion 112 should be as small as possible on the basis of satisfying the engraving area, which is conducive to reducing the processing difficulty of the lens barrel 100.
[0041] Further, see Figure 1 The plurality of reinforcing ribs 1112 and the engraved portion 112 are located on the same circumferential surface. This arrangement can simplify the structure of the lens barrel forming mold, facilitate the processing and forming of the lens barrel 100, and also improve the aesthetics of the lens barrel 100.
[0042] Optionally, continue to see Figure 1 The plurality of reinforcing ribs 1112 include at least one annular first reinforcing rib 11121. The first reinforcing rib 11121 can support the circumference of the lens barrel body 110, and has a better effect of improving the structural strength of the lens barrel body 110.
[0043] Further, see Figure 1The plurality of reinforcing ribs 1112 further include at least four second reinforcing ribs 11122 extending in the axial direction of the lens barrel body 110 and arranged at equal intervals in the circumferential direction of the lens barrel body 110. In this way, the second reinforcing ribs 11122 and the first reinforcing ribs 11121 form a mesh structure, which can make the structural strength of the lens barrel body 110 higher, and further improve the concentricity and durability of the lens barrel body 110.
[0044] Optionally, in this embodiment, six second reinforcing ribs 11122 are provided. In other embodiments, the number of second reinforcing ribs 11122 can also be set to other numbers, such as seven, eight, etc., according to actual needs, and this application does not make specific limitations.
[0045] Further, see Figure 1 The rear end of the lens barrel body 110 is provided with a cutting edge 113, which is used to position the installation of the lens in the lens barrel body 110. In the automated assembly process, the robot that assembles the lens barrel 100 and the lens intelligently identifies the position of the cutting edge 113 at the rear end of the lens barrel 100 by taking photos, and then assembles the lens based on the cutting edge 113. By setting the cutting edge 113, the accuracy of lens installation can be improved, the imaging quality of the lens can be guaranteed, and the assembly efficiency can be improved.
[0046] It is worth noting that the shape and size of the cutting edge 113 can be set according to processing convenience.
[0047] This embodiment also provides a lens, comprising a base 200 and the lens barrel 100, wherein the lens barrel 100 is mounted on the base 200. Due to the use of the lens barrel 100, the lens has a beautiful appearance, clear imaging, and a long service life.
[0048] Further, see Figure 2 and Figure 3 The rear end of the lens barrel body 110 is provided with an external thread 114, and the base 200 is provided with a threaded hole 210. The lens barrel body 110 is connected to the threaded hole 210 through the external thread 114, and the lens barrel body 110 and the base 200 are fixed by colloid.
[0049] The assembly steps of the lens barrel 100 and the base 200 are as follows:
[0050] The rear end of the lens barrel body 110 is screwed into the threaded hole 210 , and then glue is dispensed at the gap between the lens barrel body 110 and the base 200 , and then a light is shone on the glue to solidify the glue.
[0051] When the glue is dispensed and encounters the engraved part 112, the amount of glue used is less than that used in the hollowed-out part 111, thereby improving the efficiency of glue dispensing. Moreover, since the amount of glue used is small, the risk of the glue not drying is lower, thereby improving the quality of glue dispensing.
[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
