Description

Technical Field

[0001] This utility model belongs to the field of lens disassembly technology, specifically relating to a disassembly tool for disassembling a lens waterproof film. Background Technology

[0002] In the field of professional photography equipment, especially for lenses used in underwater shooting such as cinema lenses and underwater cameras, a lens waterproofing film is typically installed at the front of the lens to achieve sealing, waterproofing, and protection of the lens's internal optical structure. Existing lens waterproofing film structures mainly fall into two categories: one is a circular lens waterproofing film, which is usually embedded in a metal component and mechanically pressed in place by a pressure ring, with waterproof adhesive applied around the pressure ring to enhance the seal; the other is a square lens waterproofing film, which is often fixed to the lens frame by directly applying waterproof adhesive. Regardless of the method used, the lens waterproofing film forms a high bonding strength with the surrounding structure during lens assembly, thus ensuring sufficient stability and sealing performance in complex underwater environments.

[0003] In scenarios such as lens repair, optical structure cleaning, and internal component replacement, lens waterproofing sheets need to be removed. However, due to the high strength and strong adhesion of the cured waterproofing adhesive, coupled with the use of pressure rings in some structures, lens waterproofing sheets are extremely difficult to remove. Currently, the common method is to use a heat gun to heat the area around the lens waterproofing sheet, softening the adhesive, and then using a suction cup to pull it out. However, this method has significant drawbacks: firstly, the high-temperature heating process can easily damage the lens's metal parts, optical coatings, and rubber materials; secondly, the suction cup itself is prone to deformation or aging at high temperatures, leading to a decrease in adhesion and making it impossible to remove the lens waterproofing sheet smoothly. For some lens waterproofing sheets with stronger curing or less than ideal stress conditions, even after prolonged heating, they remain difficult to detach, sometimes necessitating destructive removal. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a disassembly tool for removing a lens waterproof film, comprising a fixture body and an adhesive layer. The fixture body has an integrally formed large outer diameter portion and a small outer diameter portion. The end face of the small outer diameter portion is an attachment surface. The adhesive layer is disposed on the outer side of the attachment surface. The adhesive layer is detachably bonded to the surface of the lens waterproof film. The area of ​​the adhesive layer is smaller than the area of ​​the lens waterproof film, so that the attachment surface can be completely adhered to the surface of the lens waterproof film.

[0005] Preferably, the adhesive layer is a strong double-sided adhesive.

[0006] Preferably, a stepped shoulder is provided between the large outer diameter portion and the small outer diameter portion.

[0007] Preferably, the axial length of the tooling body is greater than the diameter of the large outer diameter portion.

[0008] Preferably, the area of ​​the adhesive layer is 70%-90% of the area of ​​the lens waterproof film.

[0009] The advantages of this utility model are: 1. This tool features a one-piece molded cylindrical structure with a stepped shoulder that creates a clear gripping position, allowing the operator to easily apply force to complete pulling actions even in confined spaces. The attachment surface of the small outer diameter section has been optimized; simply apply double-sided tape before use. The entire process requires no professional equipment, making it intuitive and convenient, and significantly improving disassembly efficiency.

[0010] 2. This solution utilizes a combination of a small-diameter adhesive surface and strong double-sided adhesive to achieve rapid removal of the lens waterproofing film at room temperature, eliminating the need for traditional heating and softening processes. This avoids lens deformation, coating damage, or heat-induced impacts on the internal structure caused by heat. Furthermore, the selected double-sided adhesive is residue-free, leaving no adhesive residue on the glass surface and ensuring the continued usability of the lens waterproofing film.

[0011] 3. The small outer diameter and adhesion area of ​​this tool can cover waterproof films for round and square lenses of different sizes, making it suitable for various lens structures. The adhesive layer uses cuttable double-sided tape, which can be quickly replaced after its adhesion weakens, allowing the tooling body to be reused for a long time and significantly reducing maintenance costs.

[0018] Example 1, combined with Figure 1 A disassembly tool for removing a lens waterproofing film includes a fixture body 1 and an adhesive layer 2. The fixture body 1 has a one-piece molded structure, is cylindrical in shape, and has a large outer diameter portion 3 and a small outer diameter portion 4 at both ends. The end face of the small outer diameter portion 4 is machined into a flat attachment surface 5, used to fully contact the front of the lens waterproofing film 6 and attach the adhesive layer 2. The adhesive layer 2 is located on the outer side of the attachment surface 5, connecting to the surface of the lens waterproofing film 6 through strong adhesion, and pulling the lens waterproofing film 6 away from its installation position when external force is applied. A stepped shoulder 7 transitions between the large outer diameter portion 3 and the small outer diameter portion 4 of the fixture body 1, forming a clear gripping boundary. When applying external force, the operator can grip the stepped shoulder with their fingers, ensuring sufficient gripping force during the pulling operation and preventing the tool from slipping from the hand. Figure 1 The central axis and the axial length of the tooling body 1 have been optimized to make its length greater than the diameter of the large outer diameter part 3, ensuring that the operator can easily grip it and making it suitable for different hand shapes and different operating methods.

[0019] The tooling body 1 can be made of materials such as aluminum alloy, 304 stainless steel, brass, or high-strength engineering plastics, with aluminum alloy being the preferred material due to its lightweight, high strength, and resistance to deformation. To enhance the stability of the adhesive layer 2 during use, the bonding surface 5 of the small outer diameter portion 4 can be treated with fine wire drawing, sandblasting, or micro-texturing to prevent the strong double-sided adhesive from slipping or shifting during use, thereby ensuring that the entire tool can provide stable pulling force during disassembly. In this embodiment, the area of ​​the adhesive layer 2 on the tooling body 1 is preferably 70% to 90% of the area of ​​the lens waterproof film 6. For example, for a circular lens waterproof film 6 with an outer diameter of 26 mm, the adhesive layer 2 can be an adhesive layer with an outer diameter of 20 mm to 23 mm, so that the adhesive layer 2 can cover the effective area of ​​the lens waterproof film 6 and ensure firm adhesion.

[0020] The adhesive layer 2 is preferably a strong double-sided adhesive, particularly 3M's residue-free double-sided adhesive, which has high adhesion, can be reused multiple times, and leaves no adhesive residue on the glass surface. The thickness of the double-sided adhesive can range from 0.5mm to 1mm, providing sufficient bonding area while absorbing slight unevenness differences on the lens surface, resulting in a tighter fit. In actual use, the operator only needs to cut the appropriate size of double-sided adhesive and attach it to the end face of the small outer diameter part 4 to complete the preparation work.

[0021] During disassembly, first remove the retaining ring on the outside of the lens that secures the circular lens waterproof film 6, exposing the lens waterproof film 6 at the front of the lens. Then, align the adhesive surface 5 of the fixture body 1 (with double-sided adhesive applied) with the surface of the lens waterproof film 6, maintaining axial alignment, and apply appropriate pressure to ensure full contact and tight adhesion between the double-sided adhesive and the surface of the lens waterproof film 6. Optimal adhesion is usually achieved by pressing for 1 to 2 minutes. After adhesion, the operator places their fingers on the stepped shoulder between the large outer diameter portion 3 and the small outer diameter portion 4 of the fixture body 1, and then applies a quick, stable pull along the direction perpendicular to the lens, causing the lens waterproof film 6 to detach from the lens structure. Because the strong double-sided adhesive has extremely strong peeling ability under instantaneous pulling force, it provides sufficient pull force to overcome the adhesive strength of the waterproof film, allowing the lens waterproof film 6 to be easily removed without heating.

[0022] Combination Figure 2 The disassembly method in this embodiment also applies to the square lens waterproofing film 6. Since the square lens waterproofing film 6 is mostly directly adhered to the square lens frame 8 with waterproof adhesive, the retaining ring does not need to be removed during disassembly. The operator only needs to selectively attach the small outer diameter portion 4 of the fixture body 1 to the center of the square lens waterproofing film 6 or a position where force can be easily applied. After adhesion, the lens waterproofing film 6 can be detached from the lens frame by a quick pulling action. If the lens waterproofing film 6 has a large area, multiple adhesion and disassembly processes or the use of fixtures with different small outer diameters can be employed to obtain better mechanical properties.

[0023] After disassembly, the lens waterproof film 6 can be slowly peeled off from the adhesive layer 2. Because the double-sided adhesive has residue-free properties, it will not leave any residue on the glass surface of the lens waterproof film 6, nor will it damage the coating layer or structural edges of the lens waterproof film 6. A simple wipe is all it takes to restore its original state, allowing for continued installation and use. If the adhesive layer 2 loses its stickiness after multiple uses, simply replace it with new double-sided adhesive for continued use, making this disassembly tool highly economical.

[0024] The lens waterproofing film 6 disassembly tool provided in this embodiment has advantages such as simple structure, convenient operation, no need for heating, no damage to the lens waterproofing film 6, and reusability. Through the combination of a small-diameter adhesive surface 5 with a specific size matching and strong double-sided adhesive, the lens waterproofing film 6 can be quickly detached from the fixing structure at room temperature by instantaneous pulling, greatly improving lens maintenance efficiency, reducing repair costs, and significantly improving the reliability and safety of the disassembly operation. This tool is suitable for both round and square lens waterproofing films 6.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
