[0032] Referring to Figures 1-2 The utility model provides a kind of backflow line system with cleaning, drying hydration tray and high efficiency flow function, it include: at least two adjacent material conveying line 100, and the carrying motor module 110 being set between two material conveying line 100;One of the material conveying line 100 includes: hydration tray stacking area 101 and discharging tray area 102, and another material conveying line 100 includes: hydration tray lower tray area 103, backflow drying area 104 and hydration tray backflow cleaning area 105;
[0033] The hydration tray stacking area 101 is used to stack hydration trays and transfer the stacked hydration trays to the hydration tank by the carrying motor module 110; the unloading and separating area 102 is arranged opposite to the hydration tray stacking area 101, and a separating mechanical arm is arranged in the unloading and separating area 102, which is used to separate the hydration trays layer by layer and take out the contact lenses; the reflow drying area 104 is provided with a hot air circulation system, which is used to dry the cleaned hydration trays; the hydration tray reflow cleaning area 105 is symmetrically arranged on both sides of the reflow drying area 104 with the hydration tray unloading area 103, the hydration tray reflow cleaning area 105 cleans the empty hydration trays by high-pressure pure water injection or ultrasonic cleaning; the hydration tray unloading area 103 is connected with the hydration tray stacking area 101 by a conveying belt.
[0034] In this embodiment, at least two adjacent material conveying lines 100 and the carrying motor module 110 are arranged to realize efficient transfer of the hydration trays between different processing areas. Specifically, the hydration tray stacking area 101 can quickly transfer the stacked hydration trays to the hydration tank by the carrying motor module 110, improving the production efficiency; the separating mechanical arm in the unloading and separating area 102 can separate the hydration trays layer by layer and take out the contact lenses, ensuring the cleanliness and quality of the lenses; the reflow drying area 104 uses a hot air circulation system to dry the cleaned hydration trays, ensuring the dryness of the hydration trays; the hydration tray reflow cleaning area 105 uses high-pressure pure water injection or ultrasonic cleaning to deeply clean the empty hydration trays, effectively removing residual impurities and bacteria.
[0035] Specifically, when the hydration trays are stacked in the hydration tray stacking area 101, the carrying motor module 110 is started to stably and quickly grab and transfer the whole stack of hydration trays to the corresponding hydration tank, which can ensure efficient transfer efficiency and avoid damage to the hydration trays and the contact lenses in them due to rapid movement or improper operation. When the hydration trays are transported to the unloading and separating area 102, the separating mechanical arm will separate the hydration trays layer by layer according to the set order. During the separation process, it will gently but stably pick up the hydration trays, ensuring that there will be no collision or friction to the contact lenses in the hydration trays, thereby effectively ensuring the cleanliness and quality of the lenses. The separated empty hydration trays will be placed in order on the side, waiting for subsequent processing.
[0036] On the other hand, the hot air circulation system in the reflow drying area 104 is turned on, and high-temperature hot air is continuously blown out through the air outlets uniformly distributed in the drying area. These hot air will form a stable air circulation on the surface and inside of the hydration trays, accelerating the evaporation of moisture and quickly and effectively removing the moisture on the hydration trays without damaging the material and structure of the hydration trays, thereby ensuring that the hydration trays can reach the desired dryness after cleaning, preparing for subsequent reuse.
[0037] The hydration tray reflow cleaning area 105 located on both sides of the reflow drying area 104 also starts deep cleaning of the empty hydration tray. If high-pressure pure water spraying is used, the high-pressure pump will pressurize the pure water to the appropriate pressure, and then through the specially designed nozzle, it will impact the surface of the empty hydration tray at high speed. The strong impact of pure water can quickly flush away the residual impurities and bacteria attached to the hydration tray, which are carried away with the water flow. If ultrasonic cleaning is used, the ultrasonic generator will generate high-frequency vibration waves. These vibration waves will generate countless tiny bubbles when they propagate in the cleaning liquid. When the bubbles contact the surface of the hydration tray, they will quickly burst and release a lot of energy, which can effectively remove the dirt and bacteria on the hydration tray, so that the hydration tray is thoroughly cleaned.
[0038] In one embodiment, the two material transport lines 100 are arranged in parallel or L-shaped, and the carrying motor module 110 adopts a three-axis or multi-axis linkage mechanical arm.
[0039] Referring to Figure 3 In one embodiment, a cover plate transfer area 106 is provided between the hydration tray stacking area 101 and the hydration tray lower tray area 103, which is used to temporarily store the counterweight cover plate covering the hydration tray.
[0040] Referring to Figures 4-5 In one embodiment, the hot air circulation system of the reflow drying area 104 includes a hot air knife array 107 arranged along the drying path, and a hot oven 108 arranged near the hydration tray lower tray area 103 in the reflow drying area 104.
[0041] In this embodiment, the hot air knife array 107 uniformly covers the entire drying path, ensuring that the blown hot air has the appropriate angle, speed and temperature. When the hydration tray is transported to the reflow drying area 104, the hot air knife array 107 will start at the same time, and the high-speed ejected hot air will be like a sharp "blade", which will quickly blow away the moisture on the surface of the hydration tray. At the same time, due to the uniformity of the hot air knife array 107, each part of the hydration tray can be fully dried, avoiding the problem of local moisture or excessive dryness caused by uneven drying.
[0042] The hot oven 108 is arranged near the hydration tray lower tray area 103 in the reflow drying area 104, and when the hydration tray passes through the preliminary drying of the hot air knife array 107, it will gradually approach the hot oven 108. The heat generated by the hot oven 108 can further dry the hydration tray, ensuring that the residual moisture in the hydration tray is completely removed. At the same time, the temperature of the hot oven 108 can be accurately adjusted according to different production needs to adapt to the drying requirements of hydration trays of different materials and specifications.
[0043] Further, the hot oven 108 is divided into a pre-drying section and a fine-drying section, the temperature of the pre-drying section is set to 50-60°C, the temperature of the fine-drying section is set to 70-80°C, and a humidity sensor is arranged in each section to dynamically adjust the hot air flow.
[0044] In this embodiment, the start and operation of the hot air knife array 107 are closely coordinated with the action of the conveying motor module 110 and the material conveying line 100. When the conveying motor module 110 accurately delivers the hydration tray to the designated position of the backflow drying area 104, the material conveying line 100 will be temporarily paused, triggering the signal to start the hot air knife array 107. This ensures that the hydration tray receives the drying treatment of the hot air knife array 107 in a stable state, avoiding the problem that the hot air cannot uniformly act on the surface of the hydration tray due to shaking during transportation.
[0045] As the hydration tray gradually approaches the hot oven 108, the temperature of the pre-drying section begins to take effect. The temperature sensor monitors the temperature of the pre-drying section in real time and compares it with the set value. If the actual temperature is lower than the set value, the control system will automatically increase the power of the heating element to increase the temperature of the pre-drying section; on the contrary, if the actual temperature is higher than the set value, the control system will reduce the power of the heating element to avoid overheating damage to the hydration tray.
[0046] When the hydration tray completely enters the hot oven 108, the temperature of the fine-drying section also begins to take effect. Similarly, the temperature sensor and the control system will adjust the temperature of the fine-drying section in real time to ensure that it is always within the optimal drying range of 70-80°C. At the same time, the humidity sensor will dynamically monitor the humidity changes in the hot oven 108 and adjust the hot air flow as needed. If the humidity is too high, the control system will increase the hot air flow to speed up the evaporation speed of the moisture; if the humidity is too low, the control system will reduce the hot air flow to avoid excessive drying damage to the hydration tray.
[0047] In one embodiment, the high-pressure pure water spraying device of the hydration tray backflow cleaning area 105 includes a plurality of nozzles 109, which are staggered along the cleaning path, and the cleaning water pressure is adjustable in the range of 0.5-3MPa.
[0048] In this embodiment, the staggered nozzles 109 along the cleaning path ensure that each part of the hydration tray receives at least one high-pressure pure water spray cleaning regardless of the movement of the hydration tray. At the same time, the layout of the nozzles 109 also takes into account the shape and size of the hydration tray to ensure that all corners and gaps are thoroughly cleaned.
[0049] In one embodiment of the ultrasonic cleaning method, a transducer array with a frequency of 20-40kHz is arranged in the cleaning tank.
[0050] In this embodiment, when the hydration tray is placed in the cleaning tank, the ultrasonic waves begin to propagate in the tank, forming a dense micro-bubble. These bubbles rapidly vibrate and burst under the action of ultrasonic waves, producing a powerful impact force to strip the dirt and residual material on the surface of the hydration tray. And because the transducer array is evenly arranged, no matter how the hydration tray is placed, every point on its surface can be subjected to the same intensity of ultrasonic waves, ensuring the consistency of the cleaning effect.
[0051] In one embodiment, the conveyor belt between the hydration tray stacking area 101 and the hydration tray lower tray area 103 is a synchronous toothed belt, which is provided with anti-slip patterns and positioning protrusions corresponding to the bottom of the hydration tray, and the conveying speed is synchronized and matched with the pace of the backflow drying area 104.
[0052] In this embodiment, the tension of the conveyor belt can be precisely adjusted to ensure constant tension during long-term operation, prolong the service life of the conveyor belt, and also ensure that the hydration tray is always in a stable state during conveying, avoiding position deviation or damage of the hydration tray due to loose or tight conveyor belt. At the same time, the anti-slip patterns on the surface of the conveyor belt are made of special wear-resistant materials to prevent accidental slipping or displacement of the hydration tray during conveying.
[0053] On the other hand, the shape and size of the interface between the conveyor belt and the hydration tray lower tray area 103 closely fit the bottom of the hydration tray, ensuring that the hydration tray can be smoothly transferred from the conveyor belt to the lower tray area, and the synchronous matching of its pace with the backflow drying area 104 ensures that the speed of the conveyor belt matches the working pace of other equipment when the hydration tray enters the backflow drying area 104, so that the hydration tray can complete the drying process in the shortest time, improving production efficiency.
[0054] Further, the hydration tray is made of high-temperature-resistant polypropylene material, and is provided with a stacking positioning hole at the edge and a groove structure matching the positioning protrusions of the conveyor belt at the bottom.
[0055] In one embodiment, it further includes a central control unit for coordinated control of the motion trajectory of the handling motor module 110, the separation action of the tray separating robot, the water pressure adjustment of the backflow cleaning area, and the temperature parameters of the backflow drying area 104, and displays the equipment operation state and fault alarm information in real time through the human-computer interaction interface.
