Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to a vertical UV curing fixture for a zoom lens. Background Art

[0002] After the lens is assembled, dispensing needs to be carried out in the dispensing grooves in multiple directions, and then curing is carried out at the dispensing positions through a UV lamp. Due to the complex structure of the lens itself and its irregular appearance, multiple fixtures need to be combined to perform the UV glue curing action. Moreover, replacing the fixtures makes the entire work process cumbersome, greatly increases the cost of the integrated machine lens, and reduces the efficiency of the user. In addition, when using a UV curing lamp for irradiation curing, each dispensing position cannot be irradiated simultaneously, and the irradiation time and energy are unstable, which will reduce the mechanical properties of the lens. Secondly, the UV curing lamp belongs to strong light, and frequent irradiation is harmful to the human skin. The working efficiency is low under standard operations and is not conducive to safe production. Summary of the Utility Model

[0033] As Figure 1 shown, the present application provides a vertical UV curing fixture for a zoom lens, including a base 1, a plurality of fixed plates 2 and a lens carrier 3. Refer to Figure 2, a fitting cavity 11 is provided at the center of the base 1, and this fitting cavity 11 is used for fixedly installing the above-mentioned lens carrier 3. A number of mounting parts 12 are arranged around the side of the base 1, and the number of mounting parts 12 is used for fixedly installing a number of fixing plates 2. Mounting holes 21 are provided on the fixing plates 2, and the mounting holes 21 are used for installing the UV curing lamp 4, and a fastening structure for fixing the UV curing lamp 4 is provided, so that the UV curing lamp 4 can be aligned with the curing area of the lens on the lens carrier 3.

[0034] In a specific embodiment, the base 1 is a prism with a regular hexagon cross-section, and a cylindrical fitting cavity 11 is provided in the middle thereof. The lens carrier is embedded in this fitting cavity 11. The base 1 is provided with fixing holes on six sides as required, and the sides where the fixing holes are opened form the above-mentioned mounting parts 12. The fixing plate 2 is installed on the mounting parts 12 by screws, and the bottom surface of the fixing plate 2 is higher than or flush with the bottom surface of the base 1 to ensure that the base 1 can be placed stably. More specifically, as Figure 1 shown in the embodiment, three mounting parts 12 are arranged at intervals on the side of the base 1, and fixing plates 2 are respectively installed.

[0035] As Figure 1 shown in the specific embodiment, the fastening structure includes fastening screws. A threaded hole 22 communicating with the mounting hole 21 is provided at the upper end of the fixing plate 2. The fastening bolt 23 is screwed down in the threaded hole 22 to squeeze and fix the UV curing lamp 4, and it can be loosened upward to release, which is convenient for adjusting the position of the UV curing lamp 4 and taking it on and off.

[0036] It should be noted that the three mounting parts 12 arranged at intervals in the embodiment are not a rigid requirement, and specifically should be set in combination with the dispensing area (i.e., the curing area) of the lens. Similarly, the base 1 can also be set as other polygonal prisms to adapt to the curing area layout of different lens structures.

[0037] Combined with Figure 1 and Figure 2 , when this fixture is installed, first fix the base 1, then fixedly install the lens carrier 3 in the fitting cavity 11, place the lens on the lens carrier 3, determine the dispensing position of the lens to be processed, install the fixing plate 2 at the corresponding position, fixedly install the UV curing lamp 4 on the fixing plate 2, and lock it through the fastening structure to irradiate and cure different dispensing positions at the same time. During the lens assembly and processing process, curing belongs to the later stage of the process, which means that most parts and electronic components have been assembled before curing. Since multiple fixing plates 2 are provided to fix the UV curing lamp 4 for local targeted irradiation, it can avoid damage to other positions of the lens by the UV curing lamp 4, such as lens materials, coatings, and even electronic circuits. This structure is simple, the assembly is convenient and flexible, it can be installed and set for different models of lenses, avoiding frequent replacement of fixtures by manual labor, effectively improving operation safety and operation quality, and significantly improving work efficiency.

[0038] As shown Figure 3 in FIG. 2, a plurality of positioning holes 13 are provided at the bottom of the fitting cavity 11, and positioning posts 31 for fitting the positioning holes 13 are provided at the bottom of the lens carrier 3. When the lens carrier 3 is placed on the base 1, the positioning posts 31 are fitted into the positioning holes 13, which can effectively prevent the lens carrier 3 from accidentally rotating during the curing process, ensuring the stability and accuracy of the curing operation. Moreover, through the arrangement of a plurality of positioning holes 13, the lens carrier 3 can be flexibly switched at multiple angles, enabling it to adapt to different models of lenses or lenses with different dispensing positions for curing, significantly improving the versatility and applicability of the jig.

[0039] As shown Figure 2 in FIG. 3 Figure 3 and FIG. 4, the middle part of the lens carrier 3 is hollowed out, and a lens limiting groove 32 is provided at the upper end. A through groove 33 is provided at the upper end of the lens carrier 3, which is convenient for taking and placing the lens. In this embodiment, the lens is an integrated machine lens. The front group of the lens is placed downward in the hollowed-out area in the middle of the lens carrier 3, and the rear group of the lens is clamped in the lens limiting groove 32 at the upper end of the carrier. The lens limiting groove 32 prevents the lens from rotating and exposes the curing area above the lens carrier 3, facilitating the UV curing lamp 4 to be aligned with these curing areas to ensure the quality and efficiency of curing.

[0040] Furthermore, since the UV curing lamp 4 in this embodiment performs targeted irradiation curing at multiple points, it is necessary to control the distance between the UV curing lamp 4 and the curing area. This distance is preferably 2 cm. After determining the position, the UV curing lamp 4 is fixed through a fastening structure, thereby achieving precise irradiation of the lens curing area. In addition, it can also ensure that the curing energy obtained by multiple curing areas is unified, improving the quality of curing.

[0041] The utility model cures the lens at multiple curing areas by setting a plurality of fixing plates, which is applicable to various branch models of integrated machine lenses, precisely controls the unification of the curing energy of multiple curing areas, improves the working efficiency and operation safety, simplifies the operation process, and reduces the risk of lens damage.

[0042] The above is only the preferred embodiment of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
