Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to a lens hardening device. Background Art

[0002] During the lens processing process, it is often necessary to harden the lens. Currently, most lens hardening methods use a hardening liquid to soak the lens, and then dry the lens soaked in the hardening liquid to solidify the hardening liquid to form a transparent film, thereby increasing the hardness of the lens surface.

[0003] The traditional lens hardening method involves placing the lens in a jig, then placing both the jig and the lens in a hardening chamber filled with hardening fluid for immersion. This hardening method allows for fluid accumulation in the jig, resulting in uneven lens hardening thickness. The contact surface between the lens and the jig prevents contact with the hardening fluid for lenses whose entire product is functional, resulting in incomplete hardening. The lens typically lies flat in the jig, so for larger lenses, the amount of hardening fluid immersed at one time is limited, resulting in lower hardening efficiency. Furthermore, after immersion, the jig and lens must be removed from the hardening chamber, carrying excess hardening fluid with them and wasting it.

[0004] Therefore, there is an urgent need to propose a lens hardening device to solve the above technical problems. Utility Model Content

These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0035] This embodiment provides a lens hardening device, which improves the uniformity and efficiency of lens hardening, reduces the waste of hardening liquid, simplifies the structure, and thus reduces the cost of lens hardening.

[0036] Specifically, if Figure 1-Figure 5As shown, the lens hardening device includes a soaking box 100, a bracket 200 and a hanger 300.

[0037] The immersion box 100 includes an immersion chamber 110 filled with a hardening liquid, with the opening of the immersion chamber 110 facing upward. A bracket 200 is movably mounted on the top of the immersion box 100, facing the opening. A hanger 300 is mounted on the bracket 200 and includes a hanging rod 310 for simultaneously suspending multiple lenses 10.

[0038] It is worth noting that the lens 10 targeted by the lens hardening device comprises a lens body 11 and connecting ears 12 disposed on opposite sides of the lens body 11. The connecting ears 12 define connecting holes 13 through which the lens 10 is suspended from the hanging rod 310. The connecting ears 12 serve, on the one hand, to suspend the lens 10; on the other hand, they facilitate access to the lens 10 by the operator, preventing damage during the process and thereby improving the processing quality of the lens 10.

[0039] It is understood that when the connecting ear 12 on the lens body 11 is no longer needed during the production of the lens 10, the connecting ear 12 can be removed by milling. The connecting ear 12 can be integrally formed with the lens body 11 by injection molding.

[0040] The specific steps of using the lens hardening device to harden the lens 10 are as follows:

[0041] First, multiple lenses 10 to be hardened are hung on the hanging rod 310 of the hanger 300 through the connecting hole 13; then the bracket 200 is moved, and the bracket 200 will drive the hanger 300 and the lenses 10 on the hanger 300 to move synchronously until the bracket 200 is set on the top of the immersion box 100. At this time, the lenses 10 will be immersed in the hardening liquid in the immersion box 100; finally, after the immersion is completed, the bracket 200 is removed and the lenses 10 can be circulated.

[0042] The lens hardening device soaks the lens 10 by suspending it. This prevents liquid from accumulating on the lens 10, improving the uniformity of the hardening of the lens 10. Furthermore, compared with the prior art method of soaking the lens 10 in a flat position, the soaking tank 100 can accommodate more lenses 10, improving the efficiency of the lens 10 hardening. Furthermore, when removing the lens 10 after soaking, the hardening liquid is not excessively carried away from the soaking tank 100 by the lens 10, reducing waste of the hardening liquid. Furthermore, the lens hardening device has a simple structure and is applicable to a variety of lens models 10, offering high universality and reducing the cost of hardening the lens 10.

[0043] Further, see Figure 1 and Figure 2 The hanger 300 also includes a connecting rod 320 and a connecting plate 330. Both ends of the connecting rod 320 are connected to the bracket 200. Two connecting plates 330 are installed on the connecting rod 320. The two connecting plates 330 are respectively located at both ends of the connecting rod 320. Each connecting plate 330 is provided with a through hole. The two ends of the hanging rod 310 are respectively passed through the two through holes, and the hanging rod 310 can slide relative to the through hole.

[0044] The specific steps of using the hanger 300 to hang the lens 10 are as follows:

[0045] First, hold one end of the hanging rod 310 with your hand and pull it outwards, so that the other end of the hanging rod 310 is separated from the through hole connected to it, until a certain gap is formed between the other end of the hanging rod 310 and the connecting plate 330 provided with the through hole; then, hold the connecting ear 12 of the lens 10 by hand and hang the connecting ear 12 on the hanging rod 310 through the gap to suspend the lenses 10 until all the lenses 10 to be hardened are hung; finally, hold one end of the hanging rod 310 with your hand and push it inwards, so that the other end of the hanging rod 310 is inserted into the corresponding through hole again.

[0046] The hanger 300 has a simple structure and is convenient for hanging, taking and placing the lens 10 .

[0047] Optionally, in a possible embodiment, a plurality of hanging rods 310 may be provided, and the plurality of hanging rods 310 are spaced apart so that the hanger 300 can simultaneously hang more lenses 10 , thereby facilitating improving the hardening efficiency of the lenses 10 .

[0048] Alternatively, in a possible embodiment, the hanging rod 310 extends along the length direction of the opening. This arrangement makes the length of the hanging rod 310 as long as possible, increases the number of lenses 10 that can be hung on the hanging rod 310, and thus helps to improve the curing efficiency of the lenses 10.

[0049] Further, see Figure 2 In this embodiment, the hanging rod 310 is provided with a plurality of stoppers 311, which are spaced apart along the length of the hanging rod 310. Two adjacent stoppers 311 are used to stop a lens 10. By providing the stoppers 311 to restrict the position of the lens 10, it is possible to prevent the lenses 10 from moving on the hanging rod 310 and causing collision and wear during the transport of the bracket 200, thereby improving the production quality of the lenses 10.

[0050] Optionally, the stopper 311 and the hanging rod 310 may be integrally formed, and the diameter of the connecting hole 13 on the connecting ear 12 of the lens 10 may be greater than the sum of the radial length of the stopper 311 along the hanging rod 310 and the diameter of the hanging rod 310. This arrangement ensures that when the lens 10 is hung, the connecting hole 13 can pass through multiple stoppers 311 to reach the desired hanging position of the lens 10.

[0051] Optionally, the limiting member 311 and the hanging rod 310 can also be a split structure, and the limiting member 311 can be snap-connected to the hanging rod 310. In this way, the limiting member 311 can be installed after the lens 10 is hung, making it easier to hang the lens 10.

[0052] Further, if Figure 1 、 Figure 3 and Figure 4 The bracket 200 includes two supports 210 and a connecting rod connecting the two supports 210. The hanger 300 is detachably mounted on the supports 210. The supports 210 are used to be mounted on the soaking box 100. The bracket 200 has a simple structure and is easy to carry.

[0053] Optionally, continue with Figure 1 、 Figure 3 and Figure 4 In this embodiment, the support 210 is triangular in shape, and three support rods 220 are provided, one at each corner of the support 210. This arrangement gives the bracket 200 a triangular support structure, providing greater stability. Furthermore, the top support rod 220 can also be used as a handle, making it easier for workers to carry the bracket 200.

[0054] Optionally, continue with Figure 1 、 Figure 3 and Figure 4 , a take-and-place hole 211 can also be provided on the support 210, and the bracket 200 can be carried through the take-and-place hole 211. By providing the take-and-place hole 211, the difficulty of the staff in transporting the bracket 200 is reduced, and the provision of the take-and-place hole 211 can also reduce the weight of the bracket 200.

[0055] 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. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
