Description

Technical Field

[0001] This invention relates to the field of automated contact lens production technology, specifically to a UV curing method and system for contact lenses. Background Technology

[0002] UV curing of contact lenses is a crucial step in the entire contact lens manufacturing process. Conventional curing methods are prone to oxygen inhibition, which is the phenomenon that oxygen inhibits the polymerization reaction during photocuring or free radical polymerization. As a free radical scavenger, oxygen hinders the reaction through three mechanisms: quenching excited-state photoinitiators, combining with active free radicals to generate peroxides, and oxidizing polymerized free radicals. This results in the (contact lens) cured layer surface not being cured and performance deterioration.

[0003] Chinese invention patent document CN113968485B discloses an automatic loading and unloading curing device, comprising a loading module, a curing module, and an unloading module arranged sequentially. The loading module is equipped with a carrier for placing workpieces. A first XYZ axis conveying mechanism is provided between the loading module and the curing module. The curing module has a high-temperature channel and a downstream conveying component that passes through the high-temperature channel. A return conveying component is correspondingly provided below the downstream conveying component. The transport length of the return conveying component is greater than that of the downstream conveying component. A second XYZ axis conveying mechanism is provided between the curing module and the unloading module. This structure operates smoothly, has a high degree of automation, is easy to operate, saves labor and time costs, and is highly practical.

[0004] The existing technology involves baking and curing components, which has a certain degree of automation. However, for UV curing of contact lenses, this technology relies on temperature curing. The curing module of this technology is connected to the outside air, making it impossible to control the oxygen concentration. Furthermore, there are other transfer and handling devices between the feeding module and the curing module, resulting in a complex overall structure. Therefore, the existing technology and its specific structure cannot meet the UV curing requirements of the contact lens industry.

[0005] Therefore, in order to meet market demands, a solution is urgently needed. Summary of the Invention

The loading station drives the carrier carrying the material to be cured into the curing unit, placing the carrier carrying the material to be cured at the curing conveyor line inside the curing unit; S3. After a certain amount of carriers carrying the material to be cured are loaded onto the curing conveyor line, the sealing mechanism closes and the gas injection and discharge mechanism injects protective gas; S4. When the curing unit is curing, the gas injection and discharge mechanism injects a certain amount of low-temperature protective gas to control the curing temperature and cool the cured material; S5. After curing is completed, the sealing mechanism opens, and the unloading station removes the carriers carrying the cured material from the curing conveyor line inside the curing unit; S6.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] refer to Figure 1-6 As shown, the present invention provides a UV curing method for contact lenses, including a curing host 2, wherein the curing host 2 is provided with a sealing mechanism 4 and a gas injection and discharge mechanism 3, and the specific steps are as follows:

[0032] S1. The loading station 1 moves the carrier 5 carrying the material to be cured to the loading point of the curing host 2, and the sealing mechanism 4 opens; S2. The loading station 1 drives the carrier 5 carrying the material to be cured into the curing host 2, and places the carrier 5 carrying the material to be cured at the curing conveyor line 21 inside the curing host 2; S3. After a certain amount of carrier 5 carrying the material to be cured is loaded on the curing conveyor line 21, the sealing mechanism 4 closes and the gas injection and discharge mechanism 3 injects protective gas; S4. When the curing host 2 is curing, the gas injection and discharge mechanism 3 injects a certain amount of low-temperature protective gas to control the curing temperature and cool the cured material; S5. After curing is completed, the sealing mechanism 4 opens, and the unloading station 7 removes the carrier 5 carrying the cured material from the curing conveyor line 21 inside the curing host 2 in sequence according to the curing completion time; S6. After all the carriers 5 carrying the cured material on the curing conveyor line 21 are removed by the unloading station 7, the sealing mechanism 4 closes.

[0033] This UV curing method for contact lenses incorporates a sealed mechanism 4 to prevent dust, debris, temperature fluctuations, and other gases from affecting the curing process, thus improving the stability of the internal environment of the curing unit 2 during the curing process. A gas injection and discharge mechanism 3 connects to an external protective gas source, injecting protective gas into the curing unit 2 to reduce oxygen content and minimize oxygen inhibition. Furthermore, the gas injection and discharge mechanism 3 can control the temperature, reducing the impact of high temperatures on the curing process and improving curing quality. The loading station 1 and unloading station 7, combined with the curing conveyor line 21 located inside the curing unit 2, enable automated placement and pickup of the carrier 5, achieving automated curing operations, reducing the proportion of manual labor, and improving curing efficiency. Overall, this method improves the efficiency of UV curing for contact lenses, reduces labor costs and quality fluctuations caused by various factors, and ensures a high degree of consistency in the quality of contact lens products.

[0034] In this embodiment, both the loading station 1 and the unloading station 7 are equipped with material handling devices; the material handling devices are used to handle materials in the carrier 5. Specifically, the material handling devices are used to pick up and place contact lens materials in the carrier 5, and can employ devices including but not limited to suction cups or grippers to achieve the replenishment and collection of materials at the very end.

[0035] In this embodiment, a carrier return station 6 is also included. The carrier return steps are as follows: S7. The material pick-and-place device at the unloading station 7 takes the solidified material out of the carrier 5, and the unloading station 7 transports the empty carrier 5 to the carrier return station 6; S8. The carrier return station 6 moves the empty carrier 5 to the loading station 1; S9. After the loading station 1 picks up the empty carrier 5, the material pick-and-place device at the loading station 1 places the material to be solidified into the empty carrier 5 at the loading station 1.

[0036] Specifically, the carrier return station 6, in conjunction with the material handling device, enables the carrier 5 to move and rotate between the unloading station 7 and the loading station 1, improving the utilization rate of the carrier 5, reducing the time cost of carrier 5 during manual operation, and further enhancing the overall curing efficiency and automation level. Specifically, through the closed-loop system of "loading → curing → unloading → empty carrier return," a single machine can achieve a daily production capacity of over 100,000 pieces, which is twice that of traditional equipment.

[0037] In this embodiment, the loading station 1 includes a frame 11, on which a carrier transport mechanism 12 and a carrier transfer mechanism are also installed; S1 further includes: S11. The carrier transport mechanism 12 transports the carrier 5 carrying the material to be cured to the carrier transfer mechanism located at the loading point of the light curing host 2; S12. The carrier transfer mechanism extends the carrier 5 carrying the material to be cured into the light curing host 2 and places the carrier 5 carrying the material to be cured at the curing conveyor line 21.

[0038] Specifically, the feeding action is broken down into the adjustment action in the preparation stage and the transfer action at the curing conveyor line 21; the carrier handling mechanism 12 is responsible for the adjustment action, so that the carrier can adapt to various feeding methods and scenarios, and the carrier transfer mechanism can make the carrier adapt to the optical curing host 2 and curing conveyor line 21 with different height specifications.

[0039] In this embodiment, the vehicle transport mechanism 12 includes a transport lifting drive device 121 and a transport horizontal drive device 122, and the execution end of the transport horizontal drive device 122 is driven to be connected to the vehicle clamping device 123; S11 also includes:

[0040] S111. The transport lifting drive device 121 drives the carrier 5 carrying the material to be cured to the loading point of the light curing host 2; S112. The transport horizontal drive device 122 drives the carrier clamping device 123 to the transport lifting drive device 121, and the carrier clamping device 123 grabs the carrier 5 carrying the material to be cured and places it at the carrier transfer mechanism.

[0041] Specifically, both the lifting and conveying drive device 121 and the horizontal conveying drive device 122 can be linear motor modules, and the carrier clamping device 123 can be an electric cylinder driven gripper used to clamp the carrier 9. The carrier conveying mechanism 12 is used for the first positioning and assistance of the material to be solidified. Under the coordinated work of the lifting and conveying drive device 121 and the horizontal conveying drive device 122, the carrier clamping device 123 is driven to operate the carrier 5. The lifting and conveying drive device 121 can be adapted to various feeding methods, such as stacked carriers carried manually or mobile carriers in conjunction with automatic conveyor lines, which can transport the carrier 5 to the carrier transfer mechanism, improve the overall adaptability, and adapt to various production line scenarios.

[0042] In this embodiment, the vehicle transfer mechanism includes an adjustment lateral movement drive device 13, an adjustment lifting drive device 14 and a transfer lifting drive device 15 drivenly connected to the execution end of the adjustment lateral movement drive device 13, and a transfer lateral movement drive device 16 drivenly connected to the execution end of the transfer lifting drive device 15; the execution end of the adjustment lifting drive device 14 is provided with an adjustment frame 141, and the execution end of the transfer lateral movement drive device 16 is provided with a transfer seat 161; S12 also includes:

[0043] S121. After adjusting the lifting drive device 14 to the specified height, the carrier transport mechanism 12 places the carrier 5 carrying the material to be cured at the adjusting frame 141; S122. Adjust the transverse drive device 13 to drive the adjusting lifting drive device 14 and the transfer lifting drive device 15 to extend into the light curing host 2; S123. The transfer lifting drive device 15 and the transfer transverse drive device 16 drive the transfer seat 161 to move, lifting the carrier 5 carrying the material to be cured from the adjusting frame 141 and transferring it to the curing conveyor line 21.

[0044] Specifically, the adjustment lateral drive device 13 can be a linear motor module, the adjustment lifting drive device 14 and the transfer lifting drive device 15 can be electric cylinders, and the transfer lateral drive device 16 can be a rodless cylinder; the carrier transfer mechanism is used to transfer the carrier 5 from outside the light-curing host 2 to the curing conveyor line 21 inside the light-curing host 2.

[0045] The process involves two adjustments. The first adjustment involves the adjustment lifting drive 14 moving the adjustment frame 141 to a designated position to receive the carrier 5 carrying the material to be cured, which is transported by the carrier transport mechanism 12. Then, the adjustment lifting drive 14 and the adjustment lateral drive 13 work together to move the carrier 5 into the curing host 2. This ensures that the loading station 1 can accommodate curing hosts 2 of various sizes and heights, improving compatibility. The second adjustment is the transfer process, where the transfer lifting drive 15 and the transfer lateral drive 16 work together to drive the transfer seat 161, transferring the carrier 5 to the curing conveyor line 21. This achieves precise transfer and placement of the carrier 5, allowing the loading station 1 to accommodate curing conveyor lines 21 of different heights.

[0046] In this embodiment, both the inlet and outlet of the optical curing host 2 are provided with sealing guide grooves 22; the sealing mechanism 4 includes a sealing plate driving device 41 installed on the optical curing host 2 and a sealing plate 42 drivenly connected to the execution end of the sealing plate driving device 41; the sealing plate 42 is slidably assembled in the sealing guide groove 22.

[0047] Specifically, the sealing plate drive device can be an electric cylinder. The sealing plate 42 and the sealing guide groove 22 can seal the inlet and outlet, avoid the exchange of air inside and outside the internal light curing host 2, reduce pollution and temperature difference caused by air flow, and improve the quality of contact lens light curing operation.

[0048] In this embodiment, the gas injection and discharge mechanism 3 includes an air heat exchange component 31 installed on the curing host 2, multiple gas injection components 32 installed on the curing host 2 and connected to the gas storage device, and a gas collection device 33 installed inside the curing host 2 and connected to the gas injection components 32. When injecting protective gas, the sealing mechanism 4 is closed, the gas injection component 32 introduces the protective gas in the gas storage device into the gas collection device 33, and the gas collection device 33 releases the protective gas evenly into the chamber of the curing host 2. When controlling the temperature, the air heat exchange component 31 injects low-temperature protective gas into the curing host 2 to control the curing temperature and the cooling of the cured material.

[0049] Specifically, the gas injection mechanism regulates temperature by adjusting the flow rate ratio of inert gas and temperature-controlled gas. The air heat exchange component 31 can be a system including a condenser and a fan. The gas injection mechanism 3, in conjunction with the gas filling component 32, controls the oxygen concentration and temperature within the UV curing host 2. Nitrogen is preferably used as the protective gas to ensure that the oxygen concentration in the chamber is maintained at a low level (e.g., ≤50ppm) and the temperature is controlled at a low level (e.g., below 50℃) during UV curing. At the end of curing, rapid cooling can be performed to quickly lower the product temperature to a lower level (e.g., below 35℃).

[0050] Specifically, the four-stage gas circulation system (intake → distribution → monitoring → recovery) in the gas injection and discharge mechanism 3 dynamically adjusts the nitrogen concentration (fluctuation value ≤5ppm) through a PID algorithm, reducing energy consumption by 60% compared to the traditional replacement method; the cavity is protected by double-layer stainless steel sealing to prevent ultraviolet light penetration and nitrogen leakage. Internal cooling and intelligent real-time temperature control keep the temperature below 50℃.

[0051] In this embodiment, the top of the light-curing host 2 has an air passage 23, and the air heat exchange component 31 is mounted and covered at the air passage 23, communicating with the interior of the light-curing host 2. The light-curing host 2 also contains curing lamp groups 24 located on the upper and lower sides of the curing conveyor line 21. Specifically, a double-layer optical path design is adopted, with two groups per layer. Each group consists of an array of 8 high-power UV-LED light zones, achieving a light intensity uniformity of over 95%. Combined with the movement of the carrier (adjustable rotation speed 5-30 rpm), the irradiance deviation on the lens surface is achieved to be <5%.

[0052] The present invention also provides a UV curing system for contact lenses, used to implement the above-mentioned UV curing method for contact lenses, including a loading station 1, a curing host 2, and a unloading station 7. The curing host 2 is provided with a gas injection and discharge mechanism 3. Both the inlet and outlet of the curing host 2 are provided with sealing mechanisms 4. The curing host 2 is provided with a curing conveyor line 21 that does not extend out of the curing host 2. The starting end of the curing conveyor line 21 is located at the inlet of the curing host 2, and the ending end of the curing conveyor line 21 is located at the outlet of the curing host 2.

[0053] This invention and system achieve a daily production capacity of 100,000 UV curing lenses per machine through collaborative operation, significantly reducing labor costs and quality fluctuations caused by human factors. Through intelligent control, it achieves a high degree of consistency in lens quality and is suitable for the production of UV curing sections for lenses made of various materials such as silicone hydrogel and hydrogel. It is a truly green and intelligent manufacturing system, with technologies such as nitrogen circulation and LED energy saving, reducing the carbon footprint by 60% compared to traditional production lines.

[0054] The specific embodiments described herein are merely illustrative examples illustrating the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the scope defined by the spirit of the invention.
