Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically to a lens adhesive removal auxiliary device. Background Technology

[0002] In the manufacturing process of optical lenses, it is often necessary to glue two lenses of different sizes together. Due to the difference in the outer diameter of the two lenses, glue overflow is common during the gluing process. There are usually specific requirements regarding the size of the overflowing glue, so removing the overflowing glue becomes a common and important step.

[0003] Currently, traditional methods and devices for removing adhesive from lenses have many drawbacks. Some methods use manual tools, such as scrapers, for adhesive removal. This method relies on manual operation, requiring a high level of skill from the operator, and it is difficult to precisely control the force and range during the operation. If too much force is applied, the lens surface can be scratched, affecting the lens's optical performance and reducing its light transmittance and image quality; if too little force is applied, the adhesive cannot be effectively removed, resulting in incomplete removal. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses an auxiliary device for removing adhesive from lenses.

[0005] To achieve the above objectives, this application discloses a lens adhesive removal auxiliary device, comprising a tube and a needle: a hollow stud is provided at the lower end of the tube, a threaded sleeve is sleeved on the outside of the hollow stud, and a compression spring is provided inside the threaded sleeve;

[0006] The needle body includes a needle tube and a hollow column connected to the tail end of the needle tube. The diameter of the hollow column is larger than that of the needle tube and smaller than the inner diameter of the outer end of the threaded sleeve. During installation, the hollow column is located inside the threaded sleeve, and its end is in contact with the compression spring. The other end of the compression spring acts on the hollow stud.

[0007] A piston is installed inside the tube, and the piston is sealed to the tube. The other end of the piston is connected to a push rod, and the outer end of the push rod is connected to a push block. The push block is engaged in a sliding hole opened along the length of the tube.

[0008] The hollow column is provided with a first sealing gasket at its end, and a second sealing gasket is provided on the side of the tube body that contacts the threaded sleeve.

[0009] A notch is provided on one side of the bottom of the needle.

[0010] The inner cavity of the needle is filled with a sponge layer.

[0011] The lens adhesive removal auxiliary device of this application connects the tube body and the needle body via a compression spring. The compression spring can adapt to the slight undulations on the lens surface and automatically adjust the force between the needle body and the lens during the adhesive removal process, avoiding instability in force due to differences in operator technique. Compared with traditional scraper adhesive removal, operators do not need to rely on extensive experience to precisely control the force, greatly reducing the skill requirements and effectively ensuring the stability of the adhesive removal process, allowing for more precise control of the adhesive removal force and range.

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] Example 1: As Figure 1-3 As shown, a lens adhesive removal auxiliary device includes a tube body 1 and a needle body 2: a hollow stud 11 is provided at the lower end of the tube body 1, a threaded sleeve 12 is sleeved on the outside of the hollow stud 11, and a compression spring 13 is provided inside the threaded sleeve 12.

[0018] The compression spring 13 is placed inside the threaded sleeve 12, serving as a buffer and elastic adjustment function. When the needle body is subjected to force, the compression spring absorbs and disperses part of the force, preventing the lens from being damaged due to excessive pressure; after the force is released, the compression spring returns the needle body to its original position, ensuring the stability of the device and its reusability.

[0019] The needle body 2 includes a needle tube 21 and a hollow column 22 connected to the tail end of the needle tube 21. The diameter of the hollow column 22 is larger than that of the needle tube 21 and smaller than the inner diameter of the outer end of the threaded sleeve 12. During installation, the hollow column 22 is located inside the threaded sleeve 12, and its end contacts and engages with the compression spring 13. The other end of the compression spring 13 acts on the hollow stud 11. The needle tube 22, with a diameter larger than that of the needle tube 21 and smaller than the inner diameter of the outer end of the threaded sleeve 12, can be smoothly installed inside the threaded sleeve 12 and effectively contact and engage with the compression spring 13. The threaded sleeve 12 is fitted over the hollow stud 11, and its internal space is used to install the compression spring 13, pressing the hollow column 22 against the compression spring 13. The needle tube 21 directly acts on the lens adhesive removal (during operation, the needle tube 21 can be rotated to stick excess adhesive onto the needle tube 21 and remove it). Its shape and size are designed according to the specific needs of lens adhesive removal; its small diameter facilitates precise removal of adhesive residue from the lens.

[0020] The lens adhesive removal auxiliary device in this embodiment connects the tube and needle body via a compression spring. The spring adapts to the subtle undulations of the lens surface, automatically adjusting the force between the needle and the lens during adhesive removal, thus preventing instability in force due to differences in operator technique. Compared to traditional scraper adhesive removal, operators do not need extensive experience to precisely control force, greatly reducing the skill requirements and effectively ensuring the stability of the adhesive removal process, allowing for more precise control of the removal force and range.

[0021] Example 2: Figure 1-4 As shown, a piston 14 is installed inside the tube 1, and the piston 14 is sealed to the tube 1. The other end of the piston 14 is connected to a push rod 15, and the outer end of the push rod 15 is connected to a push block 16. The push block 16 is engaged in a sliding hole 17 opened along the length of the tube 1. The piston 14 installed inside the tube 1 is sealed to the tube 1, forming a relatively closed space. The piston 14 is connected to the push block 16 through the push rod 15, and the push block 16 can slide within the sliding hole 17 opened along the length of the tube 1. When the push block 16 is pulled outward, the push rod 15 drives the piston 14 to move backward, the space inside the tube 1 increases, the air pressure decreases, thereby forming a negative pressure environment. This allows external air, along with the colloid on the lens surface, to further enter the tube 1 through the needle tube 21.

[0022] A first sealing gasket 23 is provided at the end of the hollow column 22, and a second sealing gasket 18 is provided on the side of the tube body 1 that contacts the threaded sleeve 12. The first sealing gasket 23 ensures a tight connection between the hollow column 22 and the threaded sleeve 12, preventing air leakage; the second sealing gasket 18 ensures the airtightness between the tube body 1 and the threaded sleeve 12, preventing external air from entering the interior of the tube body 1 from this part.

[0023] A notch 211 is provided on one side of the bottom of the syringe 21. During the adhesive suction process, the notch can be more easily aligned with the edge or concentrated area of ​​the adhesive, making it easier for the adhesive to be sucked into the syringe 21.

[0024] The inner cavity of the syringe 21 is filled with a sponge layer 212. The sponge layer 212 can store a certain amount of colloid, preventing the colloid from falling out of the syringe 21 when not in use.

[0025] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
