Description

Technical Field

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

[0002] Optical lenses typically require coatings on their surfaces, leveraging the interference of incident, reflected, and transmitted light across the film's cross-section to achieve functions such as focusing, filtering, and reflection. Coating an optical lens typically requires a fixture to secure the lens. This fixture is then placed in a vacuum environment for vapor deposition, forming a film on the lens' surface.

[0003] Traditional lens coating jigs generally consist of a lower plate for supporting the lens and an upper plate for pressing the lens in place. The lower plate has a fixing hole, into which the lens is placed. The upper plate snaps onto the lower plate, which also has coating holes. The coating holes correspond to the fixing holes, and the portion of the lens facing the coating hole is the coating portion. The inner diameter of the coating hole is smaller than the outer diameter of the lens, enabling the upper plate to press against the outer edge of the lens to secure it. This lens coating jig structure, however, cannot achieve full coating because the upper plate obscures the outer edge of the lens. Furthermore, when coating a shaped lens, due to its shape, after coating one surface, the lens must be flipped over and secured using another lens coating jig. This requires the use of two lens coating jigs, resulting in complex procedures, low coating efficiency, and the lens's appearance can be compromised during flipping.

[0004] Therefore, it is urgent to propose a combined structure of a lens and a coating fixture to solve the above technical problems. Utility Model Content

[0005] The utility model provides a combined structure of a lens and a coating jig, which can achieve full coating of both surfaces of the lens, has a simple structure, high coating efficiency and product yield, and low coating cost.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] The combined structure of the lens and the coating fixture includes:

[0008] The lens has a plurality of connecting ears provided on the peripheral wall of the lens along the circumference of the lens, and at least two of the connecting ears are provided at opposite ends of the lens;

[0009] A coating jig, comprising a jig body, the jig body being provided with a through hole and a plurality of fixing grooves, the through hole being shaped to match the lens, the lens being mounted in the through hole, the fixing grooves being provided in a one-to-one correspondence with the connecting ears, at least a portion of the connecting ears being mounted in the fixing grooves;

[0010] A connecting structure is provided in a one-to-one correspondence with the connecting ears, and the connecting structure is used to fix the connecting ears on the fixture body.

[0011] Optionally, the connecting ear and the lens are an integrated structure.

[0012] Optionally, the fixing groove is communicated with the through hole, and glue is provided in the fixing groove. After the glue is cured, it is connected to the lens to form the connecting ear.

[0013] Optionally, there are two connecting ears, which are arranged at opposite ends of the length direction of the lens.

[0014] Optionally, along the axial direction of the through hole, supporting surfaces are provided on two opposite surfaces of the fixture body, and the supporting surfaces are higher than the coating surface of the lens on the same side.

[0015] Optionally, the connecting structure includes a first connecting hole provided on the connecting ear, a second connecting hole provided on the fixture body, and a connecting piece, wherein the connecting piece is passed through the first connecting hole and the second connecting hole to connect the connecting ear and the fixture body together.

[0016] Optionally, the connecting member is a bolt, the second connecting hole is a threaded hole, and the threaded end of the bolt passes through the first connecting hole and is connected to the threaded hole.

[0017] Optionally, the connecting structure includes a first connecting hole provided on the connecting ear and a connecting column provided on the fixture body, and the connecting column is interference fit with the first connecting hole.

[0018] Optionally, each of the connecting ears is provided with a plurality of first connecting holes, and each of the first connecting holes is correspondingly provided with a connecting column.

[0019] Beneficial effects of the utility model:

[0020] The utility model provides a combined structure of a lens and a coating jig, comprising a lens, a coating jig and a connecting structure. The lens is installed in a through hole of the coating jig, and a connecting ear is provided on the lens, and the connecting structure fixes the lens to the coating jig via the connecting ear. With such an arrangement, when the lens is coated, neither the coating jig nor the connecting structure blocks the lens, and full coating of the lens can be achieved. Since the lens is installed in the through hole, both sides of the lens that need to be coated can be exposed. After coating one side of the lens is completed, the coating jig can be turned over to continue coating the other side of the lens without disassembling the lens, and the coating process is simple. The combined structure of the lens and the coating jig is also relatively simple and low in cost.

[0021] The combined structure of the lens and the coating jig can be used for coating special-shaped lenses. Compared with the traditional coating solution for special-shaped lenses, when the combined structure of the lens and the coating jig is used to coat special-shaped lenses, after the coating of one side of the special-shaped lens is completed, the coating jig can be turned over to continue coating the other side of the special-shaped lens, eliminating the step of removing the lens from the coating jig and replacing it with another coating jig for fixation in the traditional coating solution, simplifying the coating process and thereby improving the coating efficiency. At the same time, since the step of replacing the coating jig is eliminated, the poor appearance of the lens caused by replacing the coating jig is avoided, thereby improving the product yield.

[0034] Example 1

[0035] This embodiment provides a combined structure of a lens and a coating jig, which can achieve full coating on both sides of the lens, has a simple structure, high coating efficiency and product yield, and low coating cost.

[0036] Specifically, if Figure 1-Figure 5 As shown, the combined structure of the lens and the coating jig includes a lens 100, a coating jig 200, and a connecting structure. A plurality of connecting ears 110 are provided on the peripheral wall of the lens 100 along the circumference of the lens 100, with at least two connecting ears 110 provided at opposite ends of the lens 100. The coating jig 200 includes a jig body 210, which is provided with a through hole 211 and a plurality of fixing grooves 212. The shape of the through hole 211 matches that of the lens 100, and the lens 100 is mounted in the through hole 211. The fixing grooves 212 are provided in a one-to-one correspondence with the connecting ears 110, and at least a portion of the connecting ears 110 is mounted in the fixing grooves 212. The connecting structure is provided in a one-to-one correspondence with the connecting ears 110, and the connecting structure is used to fix the connecting ears 110 to the jig body 210.

[0037] When using this lens and coating jig combination structure to coat the lens 100, neither the coating jig 200 nor the connecting structure will obstruct the lens 100, enabling full coating of the lens 100. Because the lens 100 is mounted within the through-hole 211, both sides of the lens 100 to be coated are exposed. Once coating is completed on one side of the lens 100, the coating jig 200 can be flipped over to continue coating the other side of the lens 100, eliminating the need to disassemble the lens 100 and simplifying the coating process. This lens and coating jig combination structure is also relatively simple and low-cost.

[0038] The combined structure of the lens and the coating jig can be used for coating of special-shaped lenses 100. Compared with the traditional coating scheme for special-shaped lenses 100, when the combined structure of the lens and the coating jig is used to coat the special-shaped lenses 100, after the coating of one side of the special-shaped lens 100 is completed, the coating jig 200 can be turned over to continue coating the other side of the special-shaped lens 100, eliminating the step of removing the lens 100 from the coating jig 200 and replacing it with another coating jig 200 for fixing in the traditional coating scheme, simplifying the coating process and thereby improving the coating efficiency. At the same time, since the step of replacing the coating jig 200 is eliminated, the poor appearance of the lens 100 caused by replacing the coating jig 200 is avoided, thereby improving the product yield.

[0039] Optionally, in this embodiment, two connecting ears 110 are provided, and the two connecting ears 110 are arranged at opposite ends in the length direction of the lens 100. Of course, in other embodiments, the number and arrangement of the connecting ears 110 can also be other, for example, there can be three or four connecting ears 110, etc., according to actual needs, and this application does not make any specific limitations.

[0040] It is worth noting that after the lens 100 is coated, the connecting ear 110 can be milled off using a milling device.

[0041] Alternatively, in a possible embodiment, the connecting ear 110 and the lens 100 are an integrated structure. Such a configuration not only facilitates the processing of the connecting ear 110, but also enables a better connection effect between the connecting ear 110 and the lens 100.

[0042] Optionally, in another embodiment, the fixing groove 212 is communicated with the through hole 211 , and glue is provided in the fixing groove 212 . After the glue is cured, it is connected to the lens 100 to form the connecting ear 110 .

[0043] Specifically, the lens 100 is first installed in the through hole 211, and then glue is dripped into the fixing groove 212. Since the fixing groove 212 is connected to the through hole 211, the glue dripped into the fixing groove 212 will flow into contact with the peripheral wall of the lens 100. After the glue solidifies, it is connected to the lens 100. The solidified glue forms the connecting ear 110. This arrangement is also relatively simple to process the connecting ear 110, and the connection between the connecting ear 110 and the lens 100 is also better.

[0044] Optionally, the glue may be UV glue.

[0045] Further, see Figure 1-Figure 5 , along the axial direction of the through hole 211 ( Figure 4 A supporting surface 213 is provided on two opposite surfaces of the fixture body 210 , and the supporting surface 213 is higher than the coating surface of the lens 100 on the same side.

[0046] When coating the lens 100, the coating jig 200 is placed on the coating table of the coating equipment via its supporting surface 213, i.e., the supporting surface 213 is attached to the coating table. The supporting surfaces 213 are provided on two opposing sides of the jig body 210, ensuring that the coating jig 200 can coat both sides of the lens 100. Furthermore, by setting the supporting surface 213 higher than the coating surface of the lens 100 on the same side, when coating the surface of the lens 100 away from the coating table, the surface of the lens 100 closer to the coating table will not come into contact with the coating table, thus protecting the lens 100.

[0047] Further, see Figure 4 and Figure 5 The shape of the inner wall of through-hole 211 matches the shape of the peripheral wall of lens 100. For example, in this embodiment, if lens 100 is curved, through-hole 211 also has the same curved shape as lens 100. This arrangement prevents jig body 210 from obstructing lens 100, ensuring full coating of lens 100 during coating.

[0048] Further, see Figure 1 and Figure 3 The connection structure includes a first connection hole 310 provided on the connection ear 110, a second connection hole 320 provided on the fixture body 210, and a connector. The connector is inserted through the first connection hole 310 and the second connection hole 320 to connect the connection ear 110 and the fixture body 210. This connection structure is relatively simple, has high connection strength, and simplifies the process of fixing the lens 100.

[0049] Optionally, in this embodiment, the connecting member is a bolt, the second connecting hole 320 is a threaded hole, and the threaded end of the bolt passes through the first connecting hole 310 and connects to the threaded hole. Of course, in other embodiments, the structure of the connecting member can also be other, such as a bolt-nut assembly, etc., according to actual needs, and this application does not make specific limitations.

[0050] Optionally, each connecting ear 110 may be provided with a plurality of connecting structures to improve the connection strength between the lens 100 and the coating jig 200 .

[0051] Optionally, in this embodiment, along the length direction of the connecting ear 110, a portion of the connecting ear 110 is installed in the fixing groove 212, and the remaining portion is placed outside the fixing groove 212. The first connecting hole 310 is provided in the portion of the connecting ear 110 placed outside the fixing groove 212. In other embodiments, the first connecting hole 310 can also be provided in the portion of the connecting ear 110 installed in the fixing groove 212.

[0052] Of course, the connecting ears 110 can also be completely installed in the fixing groove 212, and can be set according to actual needs. This application does not make any specific limitations.

[0054] This embodiment provides a lens and coating jig combination structure, which is substantially the same as the structure of the first embodiment, with only improvements made on the basis of the first embodiment. Therefore, only the differences between the two are described here, and the structures of this embodiment that are the same as those of the first embodiment are not repeated here.

[0055] Specifically, in the combined structure of the lens and the coating jig provided in this embodiment, the connection structure includes a first connection hole 310 provided on the connection ear 110 and a connection column provided on the jig body 210 , and the connection column is interference fit with the first connection hole 310 .

[0056] The connection structure is relatively simple, and the installation of the lens 100 is relatively convenient. In addition, the provision of the connection column also provides a guide for the installation of the lens 100 in the through hole 211 .

[0057] Optionally, each connecting ear 110 is provided with a plurality of first connecting holes 310 , and each first connecting hole 310 is provided with a corresponding connecting post. This arrangement can improve the connection strength between the lens 100 and the coating jig 200 .

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.
