Description

Technical Field

[0001] This utility model relates to the field of corneal contact lens processing technology, and in particular to a polishing machine for corneal contact lens processing. Background Technology

[0002] In the field of modern ophthalmology and vision correction, the manufacturing quality of contact lenses, as medical devices that come into direct contact with the cornea, is crucial, directly affecting the wearer's vision correction effect, eye comfort, and eye health. Polishing is a key step in the contact lens manufacturing process, determining the final quality of the lens surface and playing a decisive role in the lens's optical performance and wearing experience. However, currently used traditional contact lens polishing machines are significantly inadequate in handling the debris generated during polishing. Due to the lack of an effective containment structure design, the fine debris generated during polishing easily spreads and scatters into the surrounding environment, seriously polluting the working environment, increasing the cost and time of cleaning and maintenance, and potentially posing a threat to the health of operators. Furthermore, when different types of polishing heads need to be changed to adapt to different processing requirements, the operation process of traditional polishing machines is cumbersome and complex. Operators typically need to use multiple specialized tools and follow multiple procedures to disassemble and replace the polishing head, making the entire process time-consuming, labor-intensive, and extremely inconvenient. To address these problems, existing technologies urgently need improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polishing machine for processing corneal contact lenses.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a polishing machine for processing corneal contact lenses, including a polishing table, and further comprising: a mounting frame disposed on the polishing table; a driving component disposed on the mounting frame, the driving component including a pushing assembly and a lifting frame, the pushing assembly being used to drive the lifting frame to slide up and down along the mounting frame, the lifting frame being provided with a rotating assembly, the rotating assembly including a motor installed inside the lifting frame, a rotating shaft being fixedly connected to the end of the motor output shaft, a receiving groove being provided at the bottom end of the rotating shaft, a fixing ring being fixedly connected to the surface of the rotating shaft and a lifting handle being slidably connected, a spring being provided between the lifting handle and the fixing ring, and two positioning rods being fixedly connected to the bottom of the lifting handle; a polishing head assembly including an insertion block, the insertion block being detachably installed in the receiving groove of the rotating assembly, the top of the insertion block having two through holes for inserting the positioning rods to fix the insertion block, and a polishing head being fixedly connected to the bottom of the insertion block via a vertical column; a vertical support being disposed on the polishing table, the end of the vertical support being fixedly connected to a platform for placing the corneal contact lens to be polished; and a collecting component being slidably disposed on the surface of the vertical support for surrounding and collecting debris generated during the polishing process.

[0005] More specifically, the spring is sleeved on the rotating shaft and located between the fixed ring and the lifting handle, with both ends of the spring fixedly connected to the fixed ring and the lifting handle, respectively.

[0006] Furthermore, the collection component includes a collection cover, which is slidably mounted on the vertical support, and a linkage component is provided between the collection cover and the lifting frame.

[0007] More specifically, the two sides of the collection cover are slidably connected to the inner wall of the mounting frame via sliding plates.

[0008] Preferably, the linkage component includes: a first rack, which is fixedly connected to the side wall of the collection cover; a second rack, which is fixedly connected to the lifting frame; and a gear, which is rotatably connected to a bracket on the side wall of the mounting frame. The gear meshes with the first rack and the second rack so that when the lifting frame slides up and down, it drives the collection cover to slide up and down along the vertical support. The collection cover is used to enclose the corneal contact lens on the platform.

[0009] More preferably, the collection shroud of the collection component has an inverted conical structure, and the lower end outlet of the collection shroud faces the polishing table.

[0010] Furthermore, a collection box for collecting debris is provided at the lower outlet of the collection hood.

[0011] More specifically, the actuation component includes an electric cylinder, which is fixedly mounted on the top of the mounting bracket, with the piston rod end of the electric cylinder passing through the mounting bracket and extending downward to be fixedly connected to the top of the lifting frame.

[0012] Compared with existing technologies, this utility model has the following beneficial effects: This utility model provides a polishing machine for corneal contact lens processing. By innovatively setting up a collection component, it effectively surrounds and collects the debris generated during the polishing process using a collection cover. This fundamentally solves the problem of polishing debris easily scattering everywhere and causing pollution to the working environment in existing technologies, significantly improving the cleanliness of the working environment, reducing cleaning and maintenance costs, and creating healthier and safer working conditions for operators. At the same time, this utility model also cleverly designs a rotating component and a polishing head component, and cleverly utilizes the cooperation mechanism between the lifting handle and the positioning rod to realize the function of quick disassembly and replacement of the polishing head component. The entire replacement process does not require any auxiliary tools, making the operation simple and quick. It completely breaks through the bottleneck of the cumbersome and complicated operation process of replacing polishing heads in traditional polishing machines, greatly improving the working efficiency and ease of use of the polishing machine.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] With the continuous advancement of contact lens processing technology, the performance requirements for polishing equipment are also constantly increasing. Polishing is crucial in the precision manufacturing process of contact lenses, as its effect directly impacts the final optical quality and wearing comfort of the lens. However, existing contact lens polishing machines have revealed shortcomings in debris handling and polishing head replacement in practical applications. Specifically, traditional polishing equipment often lacks an effective debris collection mechanism, leading to the easy splashing and diffusion of tiny debris generated during polishing. This not only contaminates the working environment and increases the cleaning burden but may also pose a potential health threat to operators in the long run. Furthermore, replacing the polishing head in existing polishing machines typically requires complex tools and procedures, making the operation cumbersome and time-consuming, severely impacting production efficiency. To overcome these shortcomings of existing technologies, this application proposes a novel polishing machine solution for contact lens processing, aiming to effectively solve the problems of polishing debris contamination and inconvenient polishing head replacement, thereby improving the processing efficiency and quality of contact lenses. The core of this utility model lies in the innovative design of the polishing machine structure, which introduces a collection component 6 and a convenient polishing head assembly 34. Through ingenious structural improvements, it achieves effective collection of debris and rapid replacement of the polishing head, bringing technological innovation to the field of corneal contact lens processing.

[0021] like Figures 1 to 5 The polishing machine for processing corneal contact lenses shown includes a polishing table 1, and further includes:

[0022] Mounting bracket 2 is set on polishing table 1;

[0023] The drive component 3 is mounted on the mounting frame 2. The drive component 3 includes a push assembly and a lifting frame 32. The push assembly is used to drive the lifting frame 32 to slide up and down along the mounting frame 2. The lifting frame 32 is provided with a rotating assembly 33. The rotating assembly 33 includes a motor 331 installed inside the lifting frame 32. The output shaft end of the motor 331 is fixedly connected to a rotating shaft 332. The bottom end of the rotating shaft 332 is provided with a receiving groove 335. The surface of the rotating shaft 332 is fixedly connected to a fixing ring 336 and slidably connected to a lifting handle 334. A spring 333 is provided between the lifting handle 334 and the fixing ring 336. The bottom of the lifting handle 334 is fixedly connected to two positioning rods 337.

[0024] The polishing head assembly 34 includes an insertion block 343, which is detachably installed in the receiving groove 335 of the rotating assembly 33. The top of the insertion block 343 has two through holes 7 for inserting the positioning rod 337 to fix the insertion block 343. The bottom of the insertion block 343 is fixedly connected to the polishing head 341 via a vertical column 342.

[0025] A vertical support 5 is set on the polishing table 1, and a table plate 4 is fixedly connected to the end of the vertical support 5 for placing the corneal contact lens to be polished.

[0026] The collecting component 6 is slidably disposed on the surface of the vertical support column 5 to contain and collect the debris generated during the polishing process.

[0027] Compared with existing technologies, the polishing machine for corneal contact lens processing proposed in this invention, through the innovative introduction of a collection component 6 and a convenient polishing head assembly 34, effectively solves the problems of polishing debris pollution and cumbersome polishing head replacement while ensuring polishing effect. Traditional polishing equipment lacks an effective debris collection device, causing debris generated during polishing to easily scatter and pollute the working environment. This invention, by setting up the collection component 6, can cover the polishing area, effectively blocking and collecting debris, maintaining a clean working environment, reducing cleaning and maintenance costs, and creating a healthier working environment for operators. Furthermore, replacing the polishing head in traditional polishing machines is cumbersome, time-consuming, and labor-intensive, severely impacting work efficiency. The polishing head assembly 34 of this invention adopts a quick-disassembly structure design. Through the cooperation of the lifting handle 334 and the positioning rod 337, the polishing head assembly 34 can be quickly replaced without any tools, greatly simplifying the replacement operation, improving work efficiency, and reducing operational difficulty.

[0028] When using the polishing machine for corneal contact lens processing provided by this utility model for polishing operations, firstly, the corneal contact lens to be polished is placed on the platform 4 and fixed in place. Then, the drive component 3 is activated, pushing the component to drive the lifting frame 32 downwards along the mounting frame 2, causing the rotating component 33 and the polishing head assembly 34 to descend together, bringing the polishing head 341 close to the surface of the corneal contact lens. Once the polishing head 341 contacts the lens surface, the motor 331 in the rotating component 33 is activated. The motor 331 drives the rotating shaft 332 to rotate at high speed, thereby causing the polishing head 341 in the polishing head assembly 34 to rotate synchronously. The friction between the polishing head 341 and the lens surface achieves precise polishing of the corneal contact lens surface. Simultaneously, the collecting component 6, linked to the lifting frame 32, also moves upwards to collect the debris generated during the polishing process. When it is necessary to change to a different type of polishing head 341 to meet different polishing needs, the operator only needs to pull the lifting handle 334 upward. The lifting handle 334 overcomes the elastic force of the spring 333 and drives the positioning rod 337 upward, causing the positioning rod 337 to exit from the through hole 7 of the insertion block 343, thus releasing the fixation of the insertion block 343. At this time, the insertion block 343 can be easily removed from the receiving groove 335 at the bottom of the rotating shaft 332, realizing the quick disassembly of the polishing head assembly 34. When replacing the new polishing head assembly 34, simply align the new insertion block 343 with the receiving groove 335 and insert it. The restoring force of the spring 333 will cause the positioning rod 337 to automatically insert into the through hole 7, thus completing the quick installation of the polishing head assembly 34. The entire replacement process requires no tools and is simple and quick to operate.

[0029] In one embodiment of this utility model, the spring 333 is sleeved on the rotating shaft 332 and located between the fixing ring 336 and the lifting handle 334. The two ends of the spring 333 are fixedly connected to the fixing ring 336 and the lifting handle 334 respectively.

[0030] As one embodiment of the present invention, the collecting component 6 includes a collecting cover 61, which is slidably disposed on the vertical support column 5, and a linkage component is provided between the collecting cover 61 and the lifting frame 32.

[0031] In one embodiment of this utility model, the two sides of the collection cover 61 are slidably connected to the inner wall of the mounting frame 2 via sliding plates.

[0032] The collection cover 61 is installed above the table plate 4, surrounding the polishing area and effectively preventing the splashing and spreading of debris generated during the polishing process. Under the guidance of the collection cover 61, the debris generated during polishing is eventually collected at the bottom of the collection component 6 or in a specific collection container, keeping the working environment clean.

[0033] As one embodiment of this utility model, the linkage component includes:

[0034] The first rack 62 is fixedly connected to the side wall of the collection cover 61;

[0035] The second rack 64 is fixedly connected to the lifting frame 32;

[0036] Gear 63 is rotatably connected to the bracket on the side wall of the mounting frame 2. Gear 63 meshes with the first rack 62 and the second rack 64 so that when the lifting frame 32 slides up and down, it drives the collection cover 61 to slide up and down along the vertical support 5. The collection cover 61 is used to enclose the corneal contact lens on the platform 4.

[0037] During operation, the first rack 62 and the second rack 64 mesh with the gear 63. When the lifting frame 32 moves down, the second rack 64 drives the collection cover 61 to move up synchronously under the transmission of the gear 63.

[0038] In one embodiment of this utility model, the collection cover 61 of the collection component 6 has an inverted conical structure, and the lower end outlet of the collection cover 61 faces the polishing table 1.

[0039] As one embodiment of this utility model, a collection box for collecting debris is provided at the lower outlet of the collection cover 61.

[0040] In one embodiment of this utility model, the pushing component includes an electric cylinder 31, which is fixedly installed on the top of the mounting frame 2. The piston rod end of the electric cylinder 31 passes through the mounting frame 2 and extends downward to be fixedly connected to the top of the lifting frame 32. By using the electric cylinder 31 as the pushing component and fixing it on the top of the mounting frame 2, and fixing its piston rod end to the top of the lifting frame 32, this utility model achieves precise, stable, and reliable driving of the lifting frame 32, providing a strong guarantee for the high-precision, high-efficiency, and low-maintenance operation of the polishing machine for corneal contact lens processing.

[0041] Working principle of this utility model:

[0042] In use, the contact lens to be polished is fixed onto the platform 4 by external clamps. The platform 4 is supported by the polishing table 1. The collection cover 61 in the collection component 6 slides on the vertical support 5. When polishing the contact lens, the telescopic end of the electric cylinder 31 in the drive component 3 extends, pushing the lifting frame 32 to slide downward along the mounting bracket 2. At the same time, the motor 331 in the rotating component 33 is started. The motor 331 drives the rotating shaft 332 to rotate the insertion block 343, the vertical support 342, and the polishing head 341 in the polishing head assembly 34. The polishing head 341 polishes the surface of the contact lens. When the electric cylinder 31 drives the lifting frame 32 to move downward, it drives the second rack 64 in the collection component 6 to move downward. The second rack 64 drives the gear 63 to rotate, thereby causing the first rack 62 to move upward. The upward movement of the first rack 62 drives the collection... The cover 61 moves upward along the mounting bracket 2, thereby enclosing the clamp and corneal contact lens on the platform 4 inside the collection cover 61. In this way, during the polishing process, the collection cover 61 blocks debris from falling to the outside, and a collection box is placed at the lower outlet of the collection cover 61 to collect the debris. When it is necessary to change to a different polishing head assembly 34, the two positioning rods 337 are moved upward by pulling the lifting handle 334 upward. The spring 333 is elastically compressed by the blocking of the fixing ring 336 until the positioning rod 337 is pulled out from the through hole 7 on the insertion block 343. At this time, the positioning rod 337 no longer limits the insertion block 343. Then the insertion block 343 is moved out from the receiving groove 335 at the bottom of the rotating shaft 332, realizing convenient disassembly of the polishing head assembly 34 without the need for operating tools, and facilitating the replacement of different polishing heads 341.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
