Description

Technical Field

[0001] The utility model relates to the technical field of lens manufacturing, in particular to a lens turnover jig. Background Art

[0002] During the production and processing, lenses need to be constantly circulated between various types of equipment. When the lenses are circulated, turnover frames are generally used to load the lenses to facilitate their transportation.

[0003] Currently, to prevent poor appearance due to contact with the lens's mirror surface during placement in a recyclable frame, special-shaped lenses that require double-sided protection require protective film applied to both sides. This film must then be removed before proceeding to the next process, making the recyclable process complex and time-consuming. Furthermore, due to the high cost of specialized recyclable frames, irregularly shaped and large free-form lenses are typically transported individually, flat-laying them. This results in a smaller number of lenses per transfer, resulting in lower transport efficiency and a significant impact on lens production efficiency.

[0004] Therefore, it is urgent to propose a lens turnover fixture to solve the above technical problems. Utility Model Content

[0037] This embodiment provides a lens turnover jig for rotating special-shaped lenses, such as Figure 1 As shown, the shaped lens includes a lens body 10 and tabs 11 disposed on opposite sides of the lens body 10. This lens turnover jig can simultaneously rotate multiple shaped lenses without requiring protective film application and preventing damage to the shaped lenses during rotation. This improves the turnover efficiency of the shaped lenses, thereby increasing lens production efficiency and reducing lens production costs.

[0038] It is worth noting that the ear piece 11 on the lens body 10 can be formed during the injection molding of the special-shaped lens and cut off before the special-shaped lens is finally processed.

[0039] Specifically, if Figure 2 and Figure 3 As shown, the lens turnover jig includes a box body 100 and a stopper 200. The box body 100 is provided with a storage slot 110 for accommodating irregularly shaped lenses, and stoppers 120 are disposed on opposite sides of the storage slot 110. The bottom of the storage slot 110 is provided with a plurality of transverse ribs 111 arranged parallel and spaced along a first direction. Two adjacent transverse ribs 111 form a lens storage position 112. Each lens storage position 112 secures a irregularly shaped lens and limits the movement of the irregularly shaped lens along its thickness direction. Each stopper 120 is provided with a stopper 200, which is provided with a plurality of first engaging slots 210. The first engaging slots 210 are arranged one-to-one with the lens storage positions 112 and are configured to engage with the corresponding lugs 11.

[0040] The steps for using this lens turnover fixture to rotate special-shaped lenses are as follows:

[0041] Hold the two ear pieces 11 of the special-shaped lens, align the special-shaped lens with one of the lens storage positions 112 with the special-shaped lens in a vertical position, and align the two ear pieces 11 with the two first card slots 210 corresponding to the lens storage position 112. Then move the special-shaped lens downward along the height direction of the box body 100 until the bottom of the special-shaped lens is placed in the lens storage position 112, and the two ear pieces 11 are snapped into the corresponding first card slots 210.

[0042] Due to the provision of the ear piece 11 on the shaped lens, it is not necessary to touch the lens body 10 when placing or removing the shaped lens from the box 100. Therefore, there is no need to apply protective film to the lens body 10, which not only saves the material cost of the protective film but also shortens the transportation time of the shaped lens. In addition, the provision of the lens storage position 112 and the first slot 210 on the stopper 200 allows multiple shaped lenses to be placed in the box 100 at the same time, achieving the purpose of transporting multiple shaped lenses at the same time and further improving the transportation efficiency of the shaped lenses.

[0043] In addition, by limiting the movement of the shaped lenses in the thickness direction through the transverse ribs 111, the risk of the shaped lenses being scattered in the box body 100 can be reduced, thereby reducing the risk of the shaped lenses being damaged during transportation and improving the production qualification rate of the shaped lenses.

[0044] In this embodiment, the transverse rib 111 extends along the second direction.

[0045] Optionally, the stopper 200 can be detachably connected to the stopper portion 120. This configuration allows the stopper 200 to be replaced with a matching one according to the type of the special-shaped lens and the shape of the lug 11, thereby increasing the flexibility of the lens turnover jig and thereby increasing its universality.

[0046] Further, see Figure 2 In this embodiment, the limiting portion 120 includes two oppositely disposed limiting grooves 121, and the opposite ends of the limiting member 200 are snap-fitted into the corresponding limiting grooves 121. This snap-fit connection achieves a detachable connection between the limiting member 200 and the limiting portion 120, resulting in a simple structure and easy installation and removal.

[0047] Optionally, continue with Figure 2 The limiting portion 120 may further include two longitudinal ribs 122 arranged in parallel and spaced apart from each other, with the middle portion of the limiting member 200 being sandwiched between the two longitudinal ribs 122. The provision of the two longitudinal ribs 122 to secure the middle portion of the limiting member 200 not only improves the connection strength between the limiting portion 120 and the limiting member 200 in conjunction with the limiting groove 121, thereby improving the reliability of the limiting member 200 in securing the shaped lens; it also improves the strength of the box body 100. Since the box body 100 is generally a blister box, the increased strength of the box body 100 can reduce the risk of deformation of the box body 100, thereby improving the reliability of the box body 100 in rotating the shaped lens.

[0048] In this embodiment, the longitudinal rib 122 extends along the first direction.

[0049] Optionally, continue with Figure 2 and Figure 3In this embodiment, the stopper 200 is a strip-shaped structure. The widths of the two ends of the stopper 200 can be set larger to increase the strength of the stopper 200 and reduce the risk of deformation of the ends of the stopper 200, thereby achieving the purpose of improving the connection reliability between the stopper 200 and the stopper groove 121.

[0050] Further, see Figure 2 and Figure 3 On the box body 100, a pick-up and drop-out slot 130 is provided on the side of the stopper 200 away from the receiving slot 110. The pick-up and drop-out slot 130 is used to carry the box body 100. When carrying the box body 100, the worker can easily grasp the box body 100 through the pick-up and drop-out slot 130, reducing the risk of the box body 100 falling out of the worker's hands during the process of carrying the box body 100, thereby reducing the risk of the special-shaped lenses being scattered and damaged during the process of carrying.

[0051] Further, if Figure 4-Figure 6 As shown, the lens rotation jig further includes an upper cover 300, which is fastened to the box body 100. By providing the upper cover 300, the height movement of the shaped lens can be restricted, reducing the risk of the shaped lens shaking in the box body 100 due to rotation, thereby reducing the damage rate of the shaped lens during rotation.

[0052] Optionally, continue with Figure 4 and Figure 6 The inner top wall of the upper cover 300 is provided with a retaining rib 310, which can abut against the top of the irregularly shaped lens. The provision of the retaining rib 310 can, on the one hand, improve the retaining effect of the upper cover 300 on the irregularly shaped lens, and on the other hand, increase the strength of the upper cover 300.

[0053] Furthermore, a plurality of positioning ribs 310 are provided, and the plurality of positioning ribs 310 are arranged parallel and spaced apart along a second direction, the second direction being perpendicular to the first direction. By providing a plurality of positioning ribs 310, the shaped lens can be positioned at multiple locations on the top of the shaped lens, achieving a better positioning effect.

[0054] Further, see Figure 2 、 Figure 3 and Figure 6The inner wall of the upper cover 300 is provided with a plurality of latching protrusions 320, and the outer wall of the box body 100 is provided with a plurality of second latching grooves 140. The second latching grooves 140 are arranged in a one-to-one correspondence with the latching protrusions 320, and each latching protrusion 320 is latched into its corresponding second latching groove 140. The upper cover 300 and the box body 100 are connected by the cooperation between the latching protrusions 320 and the second latching grooves 140, making the assembly between the upper cover 300 and the box body 100 relatively simple and convenient for opening and closing the upper cover 300. The connection strength between the upper cover 300 and the box body 100 is relatively high, which can better protect the special-shaped lenses in the box body 100. In addition, the sealing performance between the box body 100 and the upper cover 300 is improved, reducing the risk of external dust contaminating the special-shaped lenses.

[0055] Optionally, continue with Figure 2 、 Figure 3 and Figure 6 The second engaging groove 140 extends through the height direction of the box body 100, and the engaging protrusion 320 extends along the height direction of the upper cover 300. The upper cover 300 is installed on the box body 100 along the height direction of the box body 100. With this arrangement, the upper cover 300 and the box body 100 can be assembled by aligning the upper cover 300 with the box body 100 and pressing the upper cover 300 down into place, further reducing the difficulty of assembling the upper cover 300 and the box body 100.

[0056] Optionally, both the upper cover 300 and the box body 100 can be formed by blister molding.

[0057] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
