Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of contact lens production equipment, and specifically relates to a contact lens hydration machine and a contact lens production line. Background Technology
[0002] In the production of contact lenses, dry contact lenses need to be hydrated, and multi-tank hydration machines are key equipment before packaging.
[0003] However, the main problem with existing technologies is that, in the continuous hydration process of current multi-tank hydration machines, the cleanliness and composition of the solution in each hydration tank vary. Because the concave side of the contact lens faces upwards, a certain amount of solution remains inside each lens during the hydration process. When the contact lens needs to be transferred to another hydration tank for further processing, the residual solution inside the lens is carried into the next hydration tank, contaminating the solution in that tank and disrupting its compositional balance. This, in turn, affects the effectiveness and quality stability of subsequent hydration processes.
[0004] In addition, existing hydration machines lack internal water flow and high-frequency vibration functions, which may make the hydration process of contact lenses incomplete and require a longer hydration time to achieve the expected hydration effect, thus affecting production efficiency.
[0005] Furthermore, the existing contact lens production lines are not equipped with automatic conveying and buffer stations, which requires frequent loading and unloading operations by equipment and operators. This not only increases the intensity of manual labor and the probability of errors, but also has obvious defects in terms of continuous equipment operation and smooth production process, making it difficult to meet the actual needs of large-scale and efficient production.
[0006] Therefore, how to overcome the above-mentioned technical defects is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0042] The core of this invention is to provide a contact lens hydration machine that adds a draining function, which can effectively solve the problem of component contamination caused by continuous hydration of different solutions in multiple hydration tanks.
[0043] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0044] For details, please refer to Figures 1-11 The present invention provides a contact lens hydration machine 100, comprising: a support frame 110, a drain tank outer shell 121, a drain tank inner shell 122, and a flipping mechanism 130.
[0045] A drain tank outer shell 121 is provided on the support frame 110. Specifically, the drain tank outer shell 121 is fixedly embedded in the support frame 110. The drain tank inner shell 122 is rotatably disposed in the inner cavity of the drain tank outer shell 121 via a rotating shaft. A flipping mechanism 130 is used to drive the drain tank inner shell 122 to flip over a preset angle. The flipping mechanism 130 can be a pneumatic flipping mechanism, which is disposed outside the drain tank outer shell 121. During draining, the drain tank inner shell 122 and the hydration basket 200 disposed in the drain tank inner shell 122 can be tilted at a certain angle by driving the rotating shaft. After draining is completed, the shell is reset.
[0046] A hydration basket 200 is placed inside the inner shell 122 of the draining tank. To maintain the stability of the hydration basket 200 when tilted, a fixing device for securing the hydration basket 200 can be provided. This embodiment provides an example solution, such as... Figure 4 and Figure 5 As shown, the fixing device consists of four (or other numbers) protrusion slots 1221 at the bottom of the hydration basket 200. The frame of the hydration basket 200 is embedded in the protrusion slots 1221 to increase stability. The protrusion slots 1221 can be an integral structure with the inner shell 122 of the draining tank, or they can be independent components. They can be fixed in the inner shell 122 of the draining tank, or they can slide together with the hydration basket 200 in the inner shell 122 of the draining tank. Furthermore, a limiting baffle 1222 is provided on the side wall inside the inner shell 122 of the draining tank to cooperate with the sliding protrusion slots 1221 to limit the hydration basket 200 in the tilted state.
[0047] Preferably, the inner shell 122 of the drain tank is provided with a sloped structure, such as forming a trapezoidal cross-section or other irregular shape, which facilitates the flipping mechanism and saves material costs. Similarly, a sloped structure can also be provided on the outer shell 121 of the drain tank.
[0048] Both the outer shell 121 and the inner shell 122 of the drain tank are provided with drain ports. Multiple drain ports can be provided to facilitate the discharge of waste liquid and reduce the formation of accumulated liquid. Preferably, the drain ports are all located at the bottom of the inner shell 122 and the outer shell 121 of the drain tank. The solution discharged from the drain port of the inner shell 122 is then discharged through the drain port of the outer shell 121.
[0049] This utility model provides a contact lens hydration machine. A draining tank outer shell 121 is mounted on a support frame 110, and a draining tank inner shell 122 is rotatably connected inside the draining tank outer shell 121. A flipping mechanism 130 drives the draining tank inner shell 122 to flip. In actual use, the hydration basket 200 is first placed in the draining tank inner shell 122. Then, the flipping mechanism 130 is controlled to flip the draining tank inner shell 122 to an appropriate angle, tilting the hydration basket 200 containing the lens and draining out any residual solution from the lens. Finally, the solution is discharged from the drain outlets of the draining tank inner shell 122 and the draining tank outer shell 121, completing the entire draining process of the hydration basket. This solution, by adding a draining function, effectively solves the problem of component contamination caused by continuous hydration of different solutions in multiple hydration tanks.
[0050] Through the rational design and combination of its components, this hydration machine can effectively drain liquid from the hydration basket. It is also easy to operate, maintain, and clean, and suitable for various hydration processes. In practical applications, the dimensions, materials, and installation methods of each component can be appropriately adjusted and optimized according to different production needs and site conditions to achieve optimal performance and results.
[0051] In a specific embodiment, such as Figure 1 As shown, this solution also includes a hydration tank 140, an ultrasonic generator 150, and a closed door 160.
[0052] A hydration tank 140 is mounted on a support frame 110. An ultrasonic generator 150 is mounted on the outer wall of the hydration tank 140 to enhance the hydration effect. The ultrasonic generator 150 generates high-frequency vibrations, which cause cavitation in the liquid within the hydration tank 140, resulting in the formation of numerous tiny bubbles that burst within a short time. When these bubbles burst, a localized high-temperature, high-pressure environment is created, accelerating the collision and contact between water molecules and the contact lens, thus promoting the hydration reaction. This configuration reduces hydration time or allows for more thorough hydration of the lens within the same timeframe.
[0053] The sealing door 160 is used to open and close the opening of the hydration tank 140. When the contact lens hydration machine is hydrating, the sealing door 160 covers the opening of the hydration tank 140 to close the opening and prevent water vapor from leaking out, while also achieving the function of heat preservation.
[0054] A set of drain tank outer shell 121 and drain tank inner shell 122 can be set together with hydration tank 140 on a support frame 110, and the two are arranged adjacent to each other.
[0055] This solution can replace traditional hydration equipment, significantly shortening hydration time and improving hydration effect. When the hydration basket 200 is transferred between multiple hydration tanks, it can increase the number of times the solution can be used, avoid solution contamination, reduce costs, improve production efficiency, and also more flexibly connect to automated equipment, such as automating the tilting mechanism and the closing door 160.
[0056] This solution also includes a drain tank 170 for collecting overflow foam from the hydration tank 140 and the solution drained from the hydration basket 200. A foam outlet 141 is provided at the upper end of the inner wall of the hydration tank 140 for discharging foam generated during the hydration process. The inlet of the drain tank 170 is connected to both the drain outlet of the drain tank shell 121 and the foam outlet 141 of the hydration tank 140, and the foam flows to the drain tank 170 through an overflow pipe. Specifically, as... Figure 1 and Figure 7 As shown, the foam outlet 141 of the hydration tank 140 is located at the upper end of the inner wall of the hydration tank 140, specifically as a straight groove, which can discharge the foam generated during the hydration process.
[0057] like Figure 7 As shown, this solution also includes an external circulation water pump 180 and an external circulation filter 1100. The outlet of the lower water tank 170 is connected to the hydration tank 140 through the external circulation water pump 180 and the external circulation filter 1100, thereby pumping the solution in the lower water tank 170 into the hydration tank 140 to achieve solution circulation. At the same time, the external circulation filter 1100 filters impurities in the solution.
[0058] Furthermore, the hydration tank 140 is equipped with a heating device for heating the solution inside the tank. Specifically, a heating plate 190 is provided on the hydration tank 140 to raise the water temperature and maintain the temperature of the solution inside the tank within the required hydration temperature range.
[0059] The hydration tank 140 is connected to the internal circulation filter 1110 and the internal circulation diaphragm pump 1120 through pipes. The internal circulation filter 1110 filters impurities in the hydration tank 140, while the internal circulation diaphragm pump 1120 circulates the solution in the hydration tank 140 and forms pulse surges to improve the hydration effect.
[0060] Valves can be installed at the drain outlets at the bottom of the outer shell 121 and inner shell 122 of the drain tank; when drainage is required, the drain outlet valves at the bottom of the outer shell 121 and inner shell 122 of the drain tank can be opened to drain the accumulated liquid. Throughout the operation, the support frame 110 provides stable support for the entire device, ensuring the normal operation of each component and the effectiveness of the hydration machine.
[0061] In a specific embodiment, such as Figure 3 As shown, the flipping mechanism 130 is a linear drive mechanism. A torsion arm is installed at one end of the rotating shaft that passes through the outer shell 121 of the drain tank. The drive end of the linear drive mechanism is connected to the torsion arm. Therefore, the linear drive mechanism can drive the torsion arm to flip the inner shell 122 of the drain tank by a preset angle.
[0062] In addition, this utility model also provides a contact lens production line, including a feeding buffer conveyor line 300, a discharging buffer conveyor line 400, a transfer mechanism 500, and a contact lens hydration machine 100, wherein the contact lens hydration machine 100 is the contact lens hydration machine in the above specific embodiment.
[0063] The feeding buffer conveyor line 300 is used to send the hydration basket 200 from the operating station to the feeding station, and the discharging buffer conveyor line 400 is used to send the hydration basket 200 from the discharging station to the operating station.
[0064] The transfer mechanism 500 is used to send the hydration basket 200 from the feeding station to the inner shell 122 of the drain tank and the hydration tank 140 of the contact lens hydration machine 100, and also to send the hydration basket 200 to the discharge station.
[0065] The feeding buffer conveyor line 300, the unloading buffer conveyor line 400, the transfer mechanism 500, and the contact lens hydration machine 100 work together to form a complete contact lens hydration treatment system. The feeding buffer conveyor line 300 is connected to the operating station and the feeding station, while the unloading buffer conveyor line 400 connects the discharging station and the operating station. The operating station can be operated manually or via other conveying mechanisms. The transfer mechanism 500 is located above the feeding station, the contact lens hydration machine 100, and the discharging station, while the contact lens hydration machine 100 serves as the main processing equipment.
[0066] like Figure 8As shown, the feeding buffer conveyor line 300 can use a belt, guide wheels, or conveyor plate to transport materials. Baffles are installed on both sides of the conveyor line to prevent the hydration basket 200 from tipping over during transport. The discharging buffer conveyor line 400 also uses a belt, guide wheels, or conveyor plate structure. The belts or guide wheels transmit power through a drive shaft and a drive motor. A stopper is also installed on one side of the operating station. The stopper includes a cylinder and a stop plate, with the cylinder's output end connected to the stop plate. When the feeding buffer conveyor line 300 / discharging buffer conveyor line 400 is not running, the cylinder raises the stop plate, restricting the movement of the hydration basket 200. When the feeding buffer conveyor line 300 / discharging buffer conveyor line 400 is running, the cylinder lowers the stop plate, placing it below the feeding buffer conveyor line 300 / discharging buffer conveyor line 400.
[0067] The contact lens hydration machine, as described in the specific embodiments above, mainly includes a draining tank inner shell 122, a hydration tank 140, a tilting mechanism 130, an ultrasonic generator 150, a heating system, a circulation system, and a control system. The draining tank inner shell 122 is made of stainless steel, with a smooth surface for easy cleaning, and its dimensions match the hydration basket 200. The hydration tank 140 is also made of stainless steel and is equipped with a heating element and a temperature sensor, which can precisely control the water temperature within a set range to meet the hydration requirements of contact lenses. The circulation system consists of various circulation pumps and pipes, enabling the hydration solution to circulate within the hydration tank, ensuring a uniform hydration effect. The control system can set parameters such as hydration time and temperature to achieve automated hydration processing.
[0068] This contact lens production line automates the contact lens hydration process through the coordinated operation of its various components, thereby improving production efficiency and product quality while reducing labor costs and operational errors.
[0069] The specific process flow of the aforementioned contact lens production line is as follows:
[0070] The hydration basket 200 containing contact lenses is placed at the operating station of the loading buffer conveyor line 300 by an operator or automated conveyor. The loading buffer conveyor line 300 starts and smoothly transports the hydration basket 200 to the feeding station. The solution in the hydration tank 140 of the contact lens hydration machine 100 is heated to the set temperature by the heating plate 190, awaiting the subsequent operation of the transfer mechanism 500. After receiving a signal, the transfer mechanism 500 grabs the hydration basket 200 and places it into the hydration tank 140 of the contact lens hydration machine 100. While hydration is taking place in the hydration tank 140, ultrasonic vibration and water circulation filtration are applied. When the hydration time reaches the preset time, the transfer mechanism 500 lifts the hydration basket 200 from the hydration tank 140 and places it into the inner shell 122 of the drain tank. The flipping mechanism is then controlled to flip the basket, achieving draining. Finally, the transfer mechanism 500 lifts the hydrated basket 200, which has completed its draining process, from the inner shell 122 of the draining tank and moves it to the discharge station, where it awaits return to the operating station by the material feeding buffer conveyor line 400. This prompts the manual / automatic conveying equipment to pick up the material, facilitating subsequent packaging or inspection work by the operator.
[0071] In a specific embodiment, such as Figures 10-11 As shown, the transfer mechanism 500 includes a gantry 510, an X-axis module 520, a Y-axis module 530, a Z-axis module 540, and a hydration basket gripper 550.
[0072] An X-axis module 520 is mounted on the crossbeam of the gantry 510 along the first direction. The X-axis module 520 typically includes components such as a guide rail, a slider, a lead screw, and a drive motor. The drive motor rotates the lead screw, which is connected to a lead screw nut mounted on the slider. When the lead screw rotates, the lead screw nut moves along the lead screw, thereby causing the connected slider to move linearly along the guide rail in the X-axis direction. A Y-axis module 530 is mounted on the slider, so that when the slider moves in the X-axis direction, the Y-axis module 530 can achieve displacement in the corresponding direction.
[0073] The Y-axis module 530 is positioned along a second direction, which is perpendicular to the first direction. Both the first and second directions are horizontal, with the first direction being the extension direction of the operating station and the feeding station. Its structure is similar to the X-axis module, including a guide rail, a slider, a lead screw, and a drive motor. The drive motor drives the lead screw of the Y-axis module to rotate, and the lead screw drives the slider connected to it to move along the guide rail in the Y-axis direction. Because the Y-axis module 530 can change position as the X-axis slider moves, the hydration basket gripper 550 can also move in the Y-axis direction.
[0074] The Z-axis module 540 is mounted on the slider of the Y-axis module 530 and is positioned along a third direction, which is vertical. Its structure is similar to that of the X-axis module. The hydration basket gripper 550 is mounted on the slider of the Z-axis module 540, which allows for vertical height adjustment of the hydration basket gripper 550. This enables the hydration basket 200 to be accurately placed at different heights within the drain tank 122, hydration tank 140, and discharge station of the contact lens hydration machine 100.
[0075] Through the coordinated operation of modules in these three directions, the gripper can move flexibly in three-dimensional space (XYZ directions), thus efficiently transferring the hydration basket between various workstations. In practical applications, the motors of each axis can be precisely controlled by a control system (such as a PLC or motion controller) to control the movement of the gripper according to a preset program and path, thereby achieving an automated production process.
[0076] The transfer mechanism 500 includes a robotic arm and a control system. The movable end of the robotic arm forms a gripper. The robotic arm is an industrial robot with at least three axes, which grips the water basket 200. The control system uses a PLC programmable controller, which is pre-programmed to automate the transfer action.
[0077] The transfer mechanism consists of a robotic arm, a vacuum suction cup system, and a control system. The robotic arm is a six-axis industrial robot with high flexibility and precision, capable of multi-angle and multi-directional movement within space. The vacuum suction cup system includes at least one suction cup, which can be made of silicone, offering good flexibility and sealing properties, and can firmly adhere to the hydration basket 200. The control system uses a PLC programmable controller, with pre-programmed procedures to automate the transfer actions.
[0078] The transfer process is as follows: the robotic arm moves the gripper / vacuum suction cup above the hydration basket 200, the gripper grabs and the vacuum suction cup starts adsorption, and the hydration basket 200 is transferred to the designated position.
[0079] To enhance the hydration effect, multiple contact lens hydration machines 100 are arranged side by side. The transfer mechanism 500 can repeatedly transfer the hydration basket 200 from the drain tank inner shell 122 of the previous contact lens hydration machine 100 to the hydration tank 140 of the next contact lens hydration machine 100, and repeat this process until hydration is completed in all hydration tanks 140. The solution ratio settings of the multiple hydration tanks 140 can be different.
