[0022] Orthokeratology is the abbreviation of highly oxygen-permeable hard corneal contact lenses for reshaping, also known as Ortho-K Lenses. Orthokeratology is a specially designed hard gas-permeable contact lens with a smaller diameter than ordinary soft contact lenses. It is worn during sleep at night and removed in the morning, which can achieve clear naked eye vision during the day without wearing any glasses.

[0023] During the processing of orthokeratology lenses, a polishing process is usually required. During the polishing process, the concave surface of the orthokeratology lens needs to be fixed on the carrier by water-soluble wax, and then the orthokeratology lens is positioned and placed in the polishing equipment with the help of the carrier. After the convex surface of the orthokeratology lens is polished using the polishing equipment, a wax dissolving process is required to separate the orthokeratology lens from the carrier. During the wax dissolving process, the carrier and the orthokeratology lens need to be placed together in a container containing warm wax-dissolving liquid, and the water-soluble wax is dissolved with the help of the wax-dissolving liquid to separate the carrier and the orthokeratology lens. However, the separated orthokeratology lens usually falls on the inner wall of the container. Since the inner wall of the container is very hard, the surface of the orthokeratology lens is easily scratched.

[0024] In view of this, the present invention provides a lens wax dissolving device and a lens wax dissolving process, aiming to improve the situation that the current orthokeratology lenses are easily scratched during the wax dissolving process. The lens wax dissolving device and the lens wax dissolving process are not limited to the wax dissolving scenarios of orthokeratology lenses, and the lens wax dissolving device and the lens wax dissolving process provided by the present invention can also be used in scenarios where other types of lenses need to be wax dissolved.

[0025] To facilitate understanding of the lens wax dissolving device provided by the present invention, the following is described in conjunction with the accompanying drawings, wherein: Figure 1 A schematic cross-sectional view of an embodiment of a lens wax dissolving device provided by the present invention; Figure 2 for Figure 1 A schematic diagram of the structure of the middle carrying part and the lens in the beginning state of wax melting; Figure 3 for Figure 1 A schematic diagram of the structure of the middle carrying part and the lens in the state where the wax dissolving is completed; Figure 4 for Figure 1 Schematic diagram of the structure in which the middle carrying part and the lens are in a separated state.

[0026] See also Figure 1 and Figure 2 In one embodiment of the present invention, the lens wax dissolving device 100 includes a wax dissolving device 1, a buffer structure 2 and a plurality of carrying parts 3. The wax dissolving device 1 has a solution tank 11 with an opening facing upward, and the solution tank 11 is used to hold the wax dissolving liquid 200; the buffer structure 2 is arranged in the solution tank 11 and is spread out on the bottom wall of the solution tank 11; the carrying part 3 has a first end 31 and a second end 32 in the up and down direction X, the first end 31 of the carrying part 3 is arranged on the buffer structure 2, and the second end 32 of the carrying part 3 is used to fix the concave surface of the lens 400 through the water-soluble wax 300.

[0027] It should be noted that the "wax dissolving device 1", that is, the container for holding the wax dissolving liquid 200, has a variety of material options, such as glass and ceramic, and a variety of possible shapes. For example, the cross-section of the solution tank 11 can be circular, square or rectangular, and the embodiment of the present invention is not limited to this; the wax dissolving liquid 200 is usually mainly composed of purified water, and a certain amount of cleaning liquid can also be mixed in order to clean and lubricate. The embodiment of the present invention does not limit the specific ratio of the cleaning liquid.

[0028] The function of the "buffer structure 2" is to be laid flat on the bottom wall of the solution tank 11 to receive the lens 400 detached from the mounting portion 3 to prevent the lens 400 from directly contacting the bottom wall of the solution tank 11; it is understandable that the hardness of the buffer structure 2 is usually lower than the hardness of the wax dissolving device 1, and there are usually a variety of material options. For example, the buffer structure 2 can be a silicone sheet, which is not limited in this embodiment.

[0029] The distribution of the "multiple carrying parts 3" on the buffer structure 2 can be in various forms, such as a circumferential array distribution, a rectangular array distribution, or an irregular distribution. However, in general, two adjacent carrying parts 3 should be arranged at intervals to provide sufficient separation and fall-off space for the lens 400. The "carrying part 3" not only needs to be able to carry the lens 400, but also usually needs to be adapted to the processing equipment in the polishing process. Therefore, there can be many structural types of the carrying part 3, which is not limited in this embodiment, and only limited to the carrying part 3 having a first end opposite to the upper and lower directions X. 31 and the second end 32, the first end 31 is used to be set on the buffer structure 2, and its specific setting form can be placed, or the two can be fixedly connected by other structures (threaded connection structure), the second end 32 is used to fix the concave surface of the lens 400 through the water-soluble wax 300, and its specific fixing method is usually to dip the second end 32 of the mounting part 3 into a certain amount of molten water-soluble wax 300, and then attach the concave surface of the lens 400 to the water-soluble wax 300, and after the water-soluble wax 300 is cooled and solidified, the mounting part 3 and the lens 400 are connected as a whole.

[0030] The technical solution provided by the present invention uses a wax dissolving device 1 to hold a wax dissolving liquid 200, and a buffer structure 2 is also flatly arranged on the bottom wall of the solution tank 11 of the wax dissolving device 1, the first end 31 of the carrying part 3 is arranged on the buffer structure 2, and the second end 32 of the carrying part 3 is fixed with a lens 400 by a water-soluble wax 300. Under the dissolving action of the wax dissolving liquid 200, the water-soluble wax 300 between the carrying part 3 and the lens 400 is dissolved, and the lens 400 is detached from the carrying part 3 and falls to the bottom of the solution tank 11. Due to the presence of the buffer structure 2, the lens 400 can be received, thereby reducing the probability of the lens 400 being scratched by the solution device 1, that is, improving the situation that the current orthokeratology lenses are easily scratched during the wax dissolving process.

[0031] See also Figure 1 and Figure 2 In one embodiment, the buffer structure 2 includes a sponge sheet 2a, and a counterweight portion 4 is installed on the lower side of the sponge sheet 2a, and the counterweight portion 4 is used to sink the sponge sheet 2a into the wax-dissolving liquid 200.

[0032] It should be noted that the "sponge sheet 2a" is a sheet-like structure. Since sponge is a porous material, the sponge sheet 2a has good cushioning properties and a lower hardness, that is, it is softer and not easy to scratch the lens 400. In order to prevent the sponge sheet 2a from floating in the wax-soluble liquid 200, in the present technical solution, a counterweight portion 4 is installed on the lower side of the sponge sheet 2a. The counterweight portion 4 should be understood as a component with a higher density and has a greater weight than the buoyancy of the sponge sheet 2a, so as to drive the sponge sheet 2a to sink into the wax-soluble liquid 200, thereby ensuring that the carrying portion 3 and the lens 400 can be completely immersed in the wax-soluble liquid 200.

[0033] The above embodiment does not limit the installation form of the sponge sheet 2a and the counterweight portion 4. In one embodiment, the counterweight portion 4 is adhesively fixed to the bottom of the sponge sheet 2a. In another embodiment, the lens wax dissolving device 100 includes a sponge shell, and the counterweight portion 4 is arranged inside the sponge shell. The upper side wall of the sponge shell includes the above-mentioned sponge sheet 2a, and the counterweight portion 4 can be stably loaded through the sponge shell.

[0034] There are many types of sponges, which can be roughly divided into natural sponges and synthetic sponges, including synthetic sponges such as polyurethane sponge (E-2 sponge), polyvinyl alcohol sponge, ethylene-vinyl acetate copolymer sponge, and foam rubber sponge. In a specific embodiment, the material of the sponge sheet 2a includes polyurethane sponge. Since the polyurethane sponge has a continuous multi-porous structure, it can absorb moisture quickly and evenly, and its pores are tiny, which can effectively capture stains and will not drop lint, which can effectively prevent the lens 400 from being contaminated. The polyurethane sponge also has excellent water absorption and water retention capabilities and softness, while maintaining good elasticity, which is sufficient to provide a good buffering effect for the lens 400 and is not easy to scratch the lens 400.

[0035] In order to adapt to the positioning fixture of the polishing equipment, the carrying part 3 is usually a columnar structure. If it is placed directly on the buffer structure 2, there is a risk of the carrying part 3 tipping over laterally. In view of this, please refer to Figure 1 In one embodiment, a through hole 22 is formed on the sponge sheet 2a and passes through in the up-down direction X; a mounting groove 41 is formed on the counterweight part 4 corresponding to the through hole 22, and the first end 31 of the carrying part 3 passes through the through hole 22 and is installed in the mounting groove 41. In the present technical solution, due to the provision of the through hole 22, the first end 31 of the carrying part 3 can pass through the sponge sheet 2a, thereby being inserted into the mounting groove 41 of the counterweight part 4, and the positioning can be easily obtained by plugging, the carrying part 3 is not easy to tip over, the safety of the lens 400 is guaranteed, and the operating pressure of the operator is also reduced. For example, the carrying part 3 can be pre-installed in the mounting groove 41 of the counterweight part 4, and then the carrying part 3, the sponge sheet 2a and the counterweight part 4 are integrally submerged in the wax-dissolving liquid 200.

[0036] In the wax dissolving liquid 200, the separated lens 400 usually does not sink vertically onto the buffer structure 2, and it may float to the side wall of the contact solution tank 11, thereby causing scratches. In view of this, please refer to Figure 1 In one embodiment, the periphery of the sponge sheet 2a abuts against the inner wall of the solution tank 11, and is closed upward to form a sponge wall 21. Since the sponge sheet 2a has good elastic deformation ability, in the technical solution, the elastic deformation ability of the sponge sheet 2a is utilized to set the size of the sponge sheet 2a larger than the size of the solution tank 11, so that as the counterweight part 4 sinks into the solution tank 11, the periphery of the sponge sheet 2a is squeezed by the interference of the side wall of the solution tank 11 and is closed upward, so that the sponge sheet 2a forms a basin-shaped sponge structure, and the sponge wall 21 is the side wall of the basin-shaped sponge structure, and the carrying part 3 is also arranged inside the basin-shaped sponge structure. The sponge wall 21 can block the sinking trajectory of the lens 400, thereby preventing the lens 400 from contacting the side wall of the solution tank 11; not only that, the sponge wall 21 can also serve as a point of force for the operator to take out the buffer structure 2, so as to facilitate the operation of the operator.

[0037] In one embodiment, the mounting portion 3 has a first side end 33 and a second side end 34 on its lateral side; the second end 32 of the mounting portion 3 has a mounting convex surface 32a, and the mounting convex surface 32a fixes the lens 400 through the water-soluble wax 300. The protruding vertex 321 of the mounting convex surface 32a is arranged closer to the first side end 33 than the second side end 34, so that the lens 400 slides toward the second side end 34 after contacting the protruding vertex 321.

[0038] Combination Figure 2 For explanation, "lateral direction of the mounting portion 3" refers to the left and right direction in the figure, "first side end 33" refers to the left side of the mounting portion 3, and "second side end 34" refers to the right side of the mounting portion 3; the second end 32 of the mounting portion 3 has a mounting convex surface 32a, which is usually a smooth and continuous arc surface, and the "protruding vertex 321" refers to the point on the mounting convex surface 32a that is farthest from the first end 31 of the mounting portion 3, and "the protruding vertex 321 is arranged closer to the first side end 33 than the second side end 34" means that the protruding vertex 321 is on the left side of the central axis of the mounting portion 3 (the dotted line in the figure).

[0039] See also Figures 2 to 4 ,exist Figure 2 In the embodiment, the carrying part 3 and the lens 400 are in the wax melting start state, at which time the water-soluble wax 300 connecting the two is still in a solid state, and the central axis of the carrying part 3 passes through the center of the lens 400; Figure 3In the embodiment, the carrying part 3 and the lens 400 are in the wax dissolving end state. At this time, the water-soluble wax 300 connecting the two is completely dissolved in the wax dissolving solution. The lens 400 first contacts the protruding vertex 321 of the carrying convex surface 32a on the carrying part 3. Since the protruding vertex 321 is closer to the first side end 33 than the second side end 34, that is, it deviates from the center of the lens 400, the lens 400 has a tendency to tilt toward the second side end 34 of the carrying part 3. Figure 4 In the embodiment, the mounting portion 3 and the lens 400 are in a wax-melted separation state, and the lens 400 is about to slide off from the second side end 34 of the mounting portion 3.

[0040] According to the above technical solution, since the protruding vertex 321 of the carrying convex surface 32a is arranged closer to the first side end 33 than the second side end 34, after the water-soluble wax 300 is dissolved, the lens 400 first contacts the protruding vertex 321. At this time, the center of the lens 400 (usually also the center of gravity) is closer to the second side end 34 of the carrying part 3 than the protruding vertex 321, so that the lens 400 slides from the second side end 34 of the carrying part 3 under the action of its own weight, which also plays a role in guiding the sliding direction of the lens 400. By adjusting the orientation of the first side end 33 and the second side end 34 of the carrying part 3, the landing point of the lens 400 on the buffer structure 2 can be artificially controlled, thereby reducing the probability of two adjacent lenses 400 sliding to the same landing point and causing collision damage.

[0041] See also Figure 1 In one embodiment, the second side ends 34 of the plurality of mounting parts 3 are arranged to face the same horizontal direction. The "horizontal direction" may be any direction in the horizontal plane, such as the left-right direction or the front-back direction, and of course, the circumferential direction in the horizontal plane. The first side ends 33 of the plurality of mounting parts 3 are arranged to face the same horizontal direction, that is, the lenses 400 on the plurality of mounting parts 3 can be guided to slide down in the horizontal direction at the same time, thereby greatly reducing the probability of collision between the lenses 400.

[0042] The lens wax dissolving process proposed in the present invention is based on the above-mentioned lens wax dissolving device 100, which at least includes a wax dissolving device 1, a buffer structure 2 and a plurality of carrying parts 3. The wax dissolving device 1 has a solution tank 11 with an opening facing upward, and the solution tank 11 is used to hold the wax dissolving liquid 200; the buffer structure 2 is arranged in the solution tank 11 and is spread out flat on the bottom wall of the solution tank 11; the carrying part 3 has a first end 31 and a second end 32 in the up and down direction X, the first end 31 of the carrying part 3 is arranged on the buffer structure 2, and the second end 32 of the carrying part 3 is used to fix the concave surface of the lens 400 through the water-soluble wax 300.

[0043] The lens wax dissolving process includes: S10, providing the above-mentioned lens wax dissolving device 100, wherein the wax dissolving device 1 contains wax dissolving liquid 200; It should be noted that the wax dissolving device 1, the buffer structure 2 and the carrying part 3 can be the structures described in any of the above embodiments, which will not be described in detail here.

[0044] S20, placing the buffer structure 2 flatly on the bottom wall of the solution tank 11 of the wax dissolving device 1, and disposing the first ends 31 of the plurality of carrying parts 3 on the buffer structure 2, so that the lens 400 is immersed in the wax dissolving liquid 200; It should be noted that "placing the buffer structure 2 flatly on the bottom wall of the solution tank 11 of the wax dissolving apparatus 1" and "setting the first ends 31 of the multiple carrying parts 3 on the buffer structure 2" are two parallel steps, and there is no necessary order between the two. However, generally speaking, placing the buffer structure 2 flatly on the bottom wall of the solution tank 11 of the wax dissolving apparatus 1 first, and then setting the first ends 31 of the multiple carrying parts 3 on the buffer structure 2, is beneficial to prevent the carrying parts 3 from tipping over on the buffer structure 2.

[0045] S30, controlling the temperature of the wax dissolving liquid 200 within the wax dissolving temperature range, and after a set time, taking out the lens 400 and the mounting part 3 that are separated from each other.

[0046] It should be noted that the "wax dissolving temperature range" can be understood as a temperature range that promotes the dissolution of the water-soluble wax 300 by the wax dissolving liquid 200, which should generally be higher than the standard room temperature. The present embodiment does not limit the specific operating method for controlling the temperature of the wax dissolving liquid 200 within the wax dissolving temperature range. For example, it can be achieved by manually measuring the temperature and heating the wax dissolving liquid 200 according to the measured temperature value.

[0047] According to the above technical scheme, by setting the buffer structure 2, and the first end 31 of the carrying part 3 is set on the buffer structure 2, under the dissolving action of the wax-dissolving liquid 200, the water-soluble wax 300 between the carrying part 3 and the lens 400 is dissolved, and the lens 400 is detached from the carrying part 3 and falls to the bottom of the solution tank 11. Due to the existence of the buffer structure 2, the lens 400 can be received, thereby reducing the probability of the lens 400 being scratched by the solution device 1, that is, improving the current situation that the orthokeratology lens is easily scratched during the wax dissolving process; not only that, the above technical scheme also limits the step of controlling the temperature of the wax-dissolving liquid 200 within the wax-dissolving temperature range, which is conducive to ensuring the dissolution rate of the water-soluble wax 300.

[0048] In one embodiment, the mounting portion 3 has a first side end 33 and a second side end 34 at the lateral side thereof, and the second end 32 of the mounting portion 3 has a mounting convex surface 32a, and the mounting convex surface 32a fixes the lens 400 through the water-soluble wax 300, and the protruding vertex 321 of the mounting convex surface 32a is arranged closer to the first side end 33 than the second side end 34; The first ends 31 of the plurality of mounting portions 3 are arranged on the buffer structure 2, including: S21, disposing the first ends 31 of the plurality of mounting portions 3 at intervals on the buffer structure 2; It should be noted that the first ends 31 of the multiple carrying parts 3 are arranged at intervals, the purpose of which is to provide space for the landing point of the lens 400 on the buffer structure 2. The spacing distribution of the multiple carrying parts 3 on the buffer structure 2 can have various forms, such as circular array distribution, rectangular array distribution, or irregular distribution.

[0049] S22, adjusting the second side ends 34 of the plurality of mounting portions 3 to face the same horizontal direction.

[0050] The second side ends 34 of the plurality of mounting parts 3 are arranged toward the same horizontal direction, which can guide the lenses 400 on the plurality of mounting parts 3 to slide toward the horizontal direction at the same time, thereby greatly reducing the probability of collision between the lenses 400 .

[0051] In a specific embodiment, the plurality of mounting portions 3 are distributed on the buffer structure 2 in a circumferential array, and the first side ends 33 of the plurality of mounting portions 3 are arranged toward the circumferential direction of the buffer structure 2, so that the first side ends 33 and the second side ends 34 of the plurality of mounting portions 3 are arranged end to end opposite to each other; After adjusting the second side ends 34 of the plurality of mounting portions 3 to face the same horizontal direction, the method further includes: The wax dissolving liquid 200 is stirred in a circumferential direction.

[0052] It should be noted that there are many ways to stir the wax soluble liquid 200 along the circumferential direction. For example, the wax soluble liquid 200 can be stirred manually or by a stirring mechanism. This embodiment does not limit this. Under the stirring action along the circumferential direction, the wax soluble liquid 200 in the solution tank 11 can swirl along the circumferential direction, thereby driving the lens 400 to detach from the mounting portion 3 from the second side end 34 along the circumferential direction, which is beneficial to improving the detachment efficiency of the lens 400.

[0053] In one embodiment, controlling the temperature of the wax dissolving liquid 200 within the wax dissolving temperature range includes: The wax dissolving apparatus 1 is placed in a constant temperature water bath, and the water bath temperature of the constant temperature water bath is adjusted to within the wax dissolving temperature range.

[0054] It should be noted that the "constant temperature water bath" is a laboratory equipment used to maintain a constant environment of liquid at a specific temperature. It is usually composed of a container filled with water or other suitable liquid and a heating element. "Placing the wax dissolving device 1 in the constant temperature water bath" means placing the wax dissolving device 1 in the container of the constant temperature water bath; the constant temperature water bath usually also has a built-in heating system and a precise temperature control system, which can stabilize the water bath temperature at a set value. In this embodiment, the set value is within the wax dissolving temperature range. The wax dissolving temperature range can be understood as a temperature range that promotes the dissolution of the water-soluble wax 300 by the wax dissolving liquid 200, which should usually be higher than the standard room temperature.

[0055] According to the above technical solution, the temperature of the wax dissolving liquid 200 can be stably controlled with the help of a constant temperature water bath, so that the temperature of the wax dissolving liquid 200 is always maintained within the wax dissolving temperature range, which is beneficial to ensure that the water-soluble wax 300 is efficiently dissolved in the wax dissolving liquid 200, thereby improving the wax dissolving efficiency of the lens 400.

[0056] In one embodiment, the wax melting temperature ranges from 30°C to 60°C.

[0057] Generally speaking, the dissolution rate of the water-soluble wax 300 is usually positively correlated with the temperature, that is, the dissolution rate increases with the increase of temperature. However, considering that too high a temperature may cause the properties of the lens 400 to change and affect the product quality of the lens 400, the present embodiment limits the wax dissolving temperature range to between 30°C and 60°C. The temperature of the wax dissolving liquid 200 can be any value between 30°C and 60°C, such as 30°C, 41.5°C, 60°C, etc., which ensures the dissolution rate of the water-soluble wax 300 while having little impact on the quality of the lens 400.

[0058] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
