[0029] Please refer to Figure 1 This embodiment provides a lens hydration device, comprising a water tank 110 and a rack 120. The water tank 110 includes a cavity 111 for holding purified water. The cavity 111 has an opening, and the rack 120 is movably disposed within the opening of the cavity 111. The rack 120 is used to hold lenses and is movable vertically to place the lenses within the purified water within the cavity 111. To fully accommodate the rack 120 within the purified water within the cavity 111, the height of the cavity 111 should be no less than that of the rack 120. When the rack 120 is placed within the cavity 111, the purified water should completely cover the rack 120 to ensure that the lenses within the rack 120 are fully hydrated.

[0030] It should be noted that, in one embodiment of the present application, there is no limitation on the specific number of the water tank 110 and the rack 120; the water tank 110 includes at least one, and correspondingly, the rack 120 also includes at least one. Figure 1 As shown, in one embodiment of the present application, the lens hydration device includes two water tanks 110 and correspondingly, two racks 120, with each water tank 110 corresponding to one rack 120. Of course, in addition to a one-to-one correspondence between the number of racks 120 and water tanks 110, multiple racks 120 may be provided within a single water tank 110. The present application does not impose any restrictions on the specific arrangement of the water tanks 110 and racks 120, as long as it ensures that all lenses placed in the racks 120 can be fully hydrated by the purified water in the water tanks 110.

[0031] The temperature of purified water in existing hydration devices can fluctuate with room temperature, and the hydration process requires a certain temperature range for purified water. Therefore, large temperature fluctuations can easily lead to poor lens hydration quality, reducing product yield. To address this issue, the lens hydration device of the present application includes a heating rod, a temperature sensor, and a controller within the cavity 111 of the water tank 110. The controller is electrically connected to the heating rod. The temperature sensor can detect the real-time temperature of the purified water and transmit the temperature signal to the controller. When the real-time temperature is less than a preset temperature range, the controller drives the heating rod to heat the purified water until the real-time temperature of the purified water is within the preset temperature range.

[0032] For example, the initial temperature of the purified water in the cavity 111 of the water tank 110 is 60 degrees Celsius, and the required hydration temperature is 78 degrees Celsius to 82 degrees Celsius. When the temperature sensor detects the real-time temperature of the purified water, the temperature signal is transmitted to the controller. The controller determines that the temperature value of the purified water at this time is lower than the required hydration temperature value range, and then drives the heating rod to heat the purified water until the real-time temperature value of the purified water is between 78 degrees Celsius and 82 degrees Celsius, so as to meet the hydration temperature requirement range and improve the product yield.

[0033] It should be noted that the present application does not impose any restrictions on the specific setting range of the required hydration temperature, and can be adjusted according to actual product needs and hydration requirements, as long as the heating rod heats the purified water temperature to within the required temperature range.

[0034] The lens hydration device can measure and heat the temperature of purified water in real time, so that the water temperature is always maintained within a preset range, thereby improving the hydration quality of the lens and the product yield.

[0035] In one possible implementation of the present application, the storage rack 120 is provided with a plurality of storage compartments arranged in an array, and a placement box is provided in the storage compartments, and the placement box is used to place lenses.

[0036] Specifically, the storage rack 120 of the lens hydration device provided in the present application has a rectangular structure, which is provided with a plurality of storage compartments arranged in an array (not shown in the figure). The storage rack 120 has a preset number of rows and a preset number of layers of storage compartments. The specific number of rows and layers can be adjusted according to the size and height of the cavity 111 of the water tank 110; each storage compartment is provided with a placement box for placing lenses.

[0037] In existing lens hydration devices, lenses are often placed in hanging cages, but the number of hanging cages is limited, resulting in low lens hydration efficiency. However, the present application provides a shelf 120 to arrange the lenses in a more orderly manner and can hydrate multiple lenses simultaneously, thereby improving the lens hydration efficiency.

[0038] Furthermore, a groove for placing lenses is provided at the bottom of the placement box; a plurality of through holes 1211 are provided on the placement box, and purified water can flow into the placement box through the through holes 1211.

[0039] Conventional lenses are typically placed in a demolding tray during the hydration process. However, when multiple lenses are placed in the demolding tray, they may become dislocated and stick together, affecting hydration efficiency and lens quality. To address this, the lens hydration device of the present application provides a recessed area at the bottom of the placement box for placing the lenses, preventing displacement of the lenses within the placement box and reducing hydration efficiency. The placement box can have multiple recesses, arranged side by side and spaced apart, to prevent adjacent lenses from sticking together while improving hydration efficiency.

[0040] Optionally, the present application does not impose any restriction on the number of placement boxes set in each storage compartment. Multiple placement boxes can be set in the storage compartment, and the multiple placement boxes are stacked. Two adjacent stacked placement boxes can be connected by snapping, which not only improves the connection stability between the placement boxes, but also improves the efficiency of lens hydration, and will not squeeze the lenses in the grooves in the placement boxes, which plays a certain protective role on the lenses.

[0041] To ensure that the purified water fully hydrates the lenses in the placement box, the placement box is provided with a plurality of through holes 1211 (not shown in the figure), through which the purified water can flow into the placement box. The present application does not impose any specific restrictions on the diameter of the through holes 1211, but the lenses should not flow out of the through holes 1211.

[0042] In an optional solution of the present application, Figure 2 As shown, the side wall of the storage rack 120 is provided with a limiting plate 121, and the storage grid is set in a receiving cavity formed by multiple limiting plates 121; the limiting plate 121 is provided with a through hole 1211, and the purified water flows into the receiving cavity through the through hole 1211 and contacts the lens.

[0043] Specifically, in order to further limit and fix the placement box in the rack 120, as shown in FIG. Figure 2 As shown, the sidewalls of the storage rack 120 are provided with a limit plate 121. The surface of the limit plate 121 is provided with multiple through-holes 1211 to ensure that the purified water in the cavity 111 flows through the through-holes 1211 into the accommodating chamber and contacts the lenses. To ensure the hydration quality of the lenses in the storage box, the multiple through-holes 1211 should be evenly distributed on the surface of the limit plate 121.

[0044] In one embodiment of the present application, the lens hydration device further includes a liquid storage component (not shown in the figure), which is used to store purified water. The liquid storage component is connected to the cavity 111 of the water tank 110 through a pipeline.

[0045] Specifically, the lens hydration device also includes a liquid storage assembly, in which purified water is stored. The provision of the liquid storage assembly improves the reliability and quality of the hydration process, facilitating the addition of pure, impurity-free water to the cavity 111 during the hydration process. The liquid storage assembly is connected to the cavity 111 of the water tank 110 via a pipe, facilitating the circulation and discharge of purified water.

[0046] Optionally, to further improve the flow efficiency of purified water, a pump head (not shown) is provided on the pipeline. The lens hydration device also includes a motor 130 electrically connected to the pump head. Motor 130 electrically drives the pump head, causing the purified water in the liquid reservoir assembly to automatically flow through the pipeline into the water tank 110, thereby improving hydration efficiency and convenience. Furthermore, after hydration is complete, the pump head can also discharge the purified water from the water tank 110.

[0047] In one embodiment of the present application, Figure 1As shown, a liquid level sensor 1111 is provided on the cavity 111 of the water tank 110, and the liquid level sensor 1111 is connected to the controller signal; the controller is electrically connected to the engine 130; the liquid level sensor 1111 can detect the real-time solution volume in the cavity 111 and transmit the liquid volume information to the controller. When the real-time solution volume is equal to the preset solution volume, the controller can drive the pump head to stop working through the engine 130.

[0048] Specifically, in order to make the purified water added to the water tank 110 more controllable, as Figure 1 As shown, a liquid level sensor 1111 is further provided in the cavity 111 of the water tank 110. The liquid level sensor 1111 is connected to the controller signal. The liquid level sensor 1111 can detect the current amount of solution in the cavity 111 in real time and transmit the liquid amount information to the controller.

[0049] The controller can compare the current liquid level with the preset solution level. If the current liquid level is less than the preset solution level, the controller can continue to drive the pump head via motor 130 to continue adding purified water to cavity 111. If the current liquid level is equal to the preset solution level, the controller can stop the pump head via motor 130 to stop adding purified water to cavity 111. This configuration improves the efficiency and controllability of the hydration process, thereby improving the hydration quality and lens quality.

[0050] In one embodiment of the present application, Figure 3 As shown, the lens hydration device also includes a linear motor 150, which includes a cylinder body and an output end. The output end is fixedly connected to the rack 120, and the output end can move along the extension direction of the cylinder body to drive the rack 120 to move in a vertical direction to approach or move away from the cavity 111 of the water tank 110.

[0051] Specifically, if Figure 3 As shown, the lens hydration device also includes a linear motor 150. The output end of the linear motor 150 is fixedly connected to the rack 120. The linear motor 150 can drive the rack 120 to move vertically toward or away from the cavity 111 of the water tank 110 through the output end. The provision of the linear motor 150 can make the movement of the rack 120 more stable and reliable. It should be noted that in addition to using the linear motor 150 to drive the movement of the rack 120, the movement of the rack 120 can also be driven by a movable cylinder. This application does not impose any restrictions on this, as long as the rack 120 can move smoothly and reliably.

[0052] Furthermore, if Figure 3As shown, since the rack 120 has a certain size, in order to improve the connection stability between the linear motor 150 and the rack 120, a connecting plate 140 is provided at the end of the output end of the linear motor 150, so that the linear motor 150 is connected to the rack 120 via the connecting plate 140. The connecting plate 140 is slidably connected to the rack 120 and can move horizontally relative to the connecting plate 140.

[0053] Specifically, the present application does not impose any restrictions on the specific connection method between the connecting plate 140 and the storage rack 120, as long as it can ensure that the storage rack 120 can move horizontally relative to the connecting plate 140. It can be a method in which a guide rod is provided on the side of the connecting plate 140 facing the storage rack 120, and a corresponding slide groove that can be slidably provided on the outer periphery of the guide rod is provided on the storage rack 120 (not shown in the figure); it can also be a method in which a guide rod is provided on the side of the connecting plate 140 facing the storage rack 120, and a linear bearing that can be slidably provided on the outer periphery of the guide rod is provided on the storage rack 120 (not shown in the figure); it can also be a method in which a guide groove is provided on the side of the connecting plate 140 facing the storage rack 120, and a slider that can be movably provided in the guide groove is provided on the storage rack 120 (not shown in the figure). The rack 120 can be moved back and forth along the surface of the connecting plate 140 through the above-mentioned connection method, and can also be moved left and right along the surface of the connecting plate 140 to accurately adjust its relative position with the cavity 111 of the water tank 110, so that the rack 120 can accurately enter the cavity 111 of the water tank 110.

[0054] In an optional solution of the present application, Figure 3 As shown, a guide rod 160 is provided in a vertical direction on the side of the water tank 110 facing the storage rack 120, and the linear motor 150 is mounted on the end of the guide rod 160 away from the water tank 110; a guide groove is provided on the side edge of the connecting plate 140, and the guide rod 160 can be inserted into the guide groove so that the connecting plate 140 slides along the guide rod 160 through the guide groove.

[0055] Specifically, the water tank 110 is provided with a guide rod 160 arranged in a vertical direction on the side facing the rack 120. Figure 3 As shown, two guide rods 160 are provided, and the two guide rods 160 are respectively arranged on opposite sides of the storage rack 120; the linear motor 150 is mounted on the end of the guide rod 160 away from the water tank 110, and the guide rod 160 can play a certain supporting role for the linear motor 150; the side edge of the connecting plate 140 is provided with a guide groove, and the guide rod 160 can be inserted into the guide groove so that the connecting plate 140 slides along the guide rod 160 through the guide groove, so that the movement process of the storage rack 120 is smoother, faster and more reliable.

[0056] The above description is merely an optional embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

[0057] The operating principle of the lens hydration device provided in this application is as follows:

[0058] First, place the unhydrated lenses in the groove of the placement box, and then insert the placement box into the storage rack 120; multiple placement boxes can be stacked in one storage rack 120;

[0059] The rack 120 with the lenses placed thereon is lowered into the cavity 111 of the water tank 110 by the linear motor 150, and the pump head is activated by the motor 130 to flow the purified water having a certain temperature and pH value in the liquid storage assembly into the cavity 111 of the water tank 110 until the liquid level sensor 1111 detects that the liquid level in the cavity 111 reaches a preset level. The controller then drives the motor 130 to stop the pump head to stop the flow of purified water.

[0060] The heating rod is started to heat the purified water in the cavity 111, and the temperature of the purified water in the cavity 111 is detected in real time by the temperature sensor until the temperature value of the purified water is within the preset temperature range. At this time, the controller stops the heating work of the heating rod; when the temperature of the purified water drops below the preset temperature range, the controller restarts the heating rod to heat the purified water in the cavity 111 until the temperature value of the purified water is within the preset temperature range again, until the hydration of the lens is completed.

[0061] When the lens hydration reaches a preset time, the linear motor 150 drives the shelf 120 to rise, and the controller can start the pump head through the motor 130 to discharge the purified water in the cavity 111 of the water tank 110.

[0062] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
