Description

Technical Field

[0001] This utility model relates to a contact lens hydration plate that facilitates automated gripping. Background Technology

[0002] Contact lenses are vision correction or cosmetic devices placed directly on the surface of the eye. During production, they undergo a hydration process to ensure their softness and comfort. Contact lens hydration refers to the process of immersing dry contact lenses in a specific solution to allow them to absorb water and reach a certain moisture content. Currently, contact lens production is gradually becoming more automated, but some technical challenges remain in the hydration stage.

[0003] In the prior art, contact lens hydration devices typically include components such as hydration tanks, carrying units, and tank displacement mechanisms. For example, CN209566518U discloses a contact lens hydration device that accurately controls the time each carrying unit stays in each hydration tank by moving the carrying units of the hydration tank one by one to the next hydration tank and by replenishing the carrying units one by one.

[0004] However, existing contact lens hydration trays have the following problems: traditional hydration trays have a simple structure, usually just a simple container structure, and lack a mechanism design that facilitates automated equipment to grasp contact lenses. They often require manual intervention to remove contact lenses, resulting in low production efficiency.

[0005] Therefore, there is an urgent need for a structurally improved contact lens hydration plate that can be easily gripped by automated equipment and improve production efficiency. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a contact lens hydration tray that facilitates automated gripping. By adding a feeding mechanism to each hydration tray, automated feeding is achieved, reducing manual intervention and increasing production efficiency. This invention achieves its purpose as follows:

[0007] This utility model proposes a contact lens hydration tray that facilitates automated gripping, comprising a tray body with a plurality of first slots arranged in a rectangular array on the tray body. A second slot is formed on the bottom surface of each of the first slots. Moving tracks are symmetrically installed inside the tray body, and connecting rods are movably installed between the moving tracks. A material-lifting rod is mounted on the connecting rod. A driving device is also installed inside the tray body, which drives the material-lifting rod to move up and down within the second slot to push the material in the first slot.

[0008] Furthermore, there are two drive devices, which are symmetrically arranged on both sides of the connecting rod. Each drive device is a motor, and the drive shaft of the motor is connected to a connecting rod. Connecting heads are installed on both sides of the connecting rod, and the connecting rod is connected to the connecting head.

[0009] Furthermore, a gap is provided inside the disc body, and the connecting rod is disposed within the gap.

[0010] Furthermore, the height of the gap is 5cm, the length of the top material rod is 9cm, and the depth of the second groove is 5cm.

[0011] Furthermore, the first slot is distributed in a 5×10 pattern.

[0012] Furthermore, the disc body is equipped with a battery inside, which is used to provide power to the drive device, and the outer surface of the disc body is provided with a charging hole, which is connected to the battery.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a driving device and a push rod structure inside the contact lens hydration tray, the push rod can move up and down in the second slot, thereby pushing the contact lens in the first slot upwards and partially exposing it from the slot, which facilitates the gripping operation of automated equipment. This solves the problem that traditional hydration trays are not easy to grip in automated production, and significantly improves the efficiency and reliability of automated production. At the same time, the battery set inside the tray and the charging port on the outer surface allow the entire device to work independently without external power supply, further improving the flexibility and convenience of use.

[0018] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0019] Example 1

[0020] An embodiment of this utility model proposes a contact lens hydration tray that facilitates automated gripping, comprising a tray body 1, on which a plurality of first slots 2 are formed, the first slots 2 being arranged in a rectangular array on the tray body 1, and a second slot 3 being formed on the bottom surface of each of the first slots 2. Moving tracks 5 are symmetrically installed inside the tray body 1, and connecting rods 7 are movably installed between the moving tracks 5. A material-lifting rod 4 is installed on the connecting rod 7. A driving device 10 is also installed inside the tray body 1, which is used to drive the material-lifting rod 4 to move up and down in the second slot 3 to push the material in the first slot 2.

[0021] Specifically, the disc body 1 is made of polypropylene material, which has good corrosion resistance and stability, making it suitable for long-term contact with aqueous solutions. The overall shape of the disc body 1 is rectangular, with a length of 30 cm, a width of 20 cm, and a height of 8 cm. The upper surface of the disc body 1 is flat for easy placement and stacking. Reinforcing ribs are designed around the edges of the disc body 1 to enhance the overall structural strength. The first slots 2 are distributed in a 5×10 rectangular array on the disc body 1, totaling 50 slots. Each first slot 2 has a diameter of 2 cm and a depth of 1.5 cm, used to hold contact lenses and their soaking solution. The spacing between the first slots 2 is 1 cm to ensure that each slot is independent and avoids cross-contamination. The inner wall of the first slot 2 is smooth for easy cleaning and disinfection. A second slot 3 is opened at the center of the bottom surface of the first slot 2. The second slot 3 has a diameter of 0.8 cm and a depth of 5 cm, extending into the interior space of the disc body 1. The inner wall of the second slot 3 is also smoothed to ensure smooth movement of the top rod 4 within it. The upper end of the second slot 3 smoothly transitions to the bottom surface of the first slot 2, avoiding dead angles. Symmetrically installed moving rails 5 are mounted inside the disc body 1. The moving rails 5 are made of stainless steel, offering good corrosion resistance and strength. The moving rails 5 are positioned along the length of the disc body 1, with a length of 28 cm, a width of 1 cm, and a height of 0.5 cm. The surface of the moving rails 5 is polished to reduce frictional resistance, ensuring smooth movement of the connecting rod 7. The moving rails 5 are fixed to the inner wall of the disc body 1 by a bracket made of the same material as the disc body 1, securely connected to the inner wall of the disc body 1 via a heat-fusion connection. A gap 8 is provided inside the disc body 1, with a height of 5 cm, a width the same as the internal width of the disc body 1, and a length the same as the internal length of the disc body 1. The gap 8 is located in the space between the bottom of the disc body 1 and the bottom end of the second slot 3, providing installation and movement space for the connecting rod 7 and the drive device 10. The inner wall of the gap 8 is smooth, avoiding obstruction of internal components. Connecting rods 7 are movably installed between the moving tracks 5, within the gap 8. Made of aluminum alloy, connecting rods 7 are lightweight and high-strength. The length of connecting rod 7 is 18 cm, matching the width of the disc body 1, with a width of 2 cm and a thickness of 0.5 cm. Both ends of the connecting rod 7 have sliders that match the moving tracks 5. These sliders are made of nylon to reduce friction and improve smooth movement. Connecting heads 6, made of stainless steel, are installed on both sides of the connecting rod 7 and are fixed to the connecting rod 7 with bolts. Ejector rods 4 are evenly installed on the connecting rod 7, with a total of 50 ejector rods corresponding to the arrangement of the first slot 2. Ejector rods 4 are made of medical-grade silicone, offering good elasticity and biocompatibility. The length of ejector rod 4 is 9 cm, and its diameter is 0.7 cm, slightly smaller than the diameter of the second slot 3, ensuring smooth movement within the second slot 3. The upper end of the ejector rod 4 is hemispherical, providing a large contact area and preventing damage to the contact lenses. The top material rod 4 is connected to the connecting rod 7 by a snap-fit ​​mechanism, which facilitates disassembly and replacement.Inside the disc body 1, there are two drive units 10, symmetrically arranged on both sides of the connecting rod 7. Each drive unit 10 is a DC micro motor with a rated voltage of 3.7V, a rated power of 2W, and a speed of 200rpm. The motor is fixed to the inner wall of the disc body 1 by a bracket made of the same material as the disc body 1, and is securely connected to the inner wall of the disc body 1 via a heat-fusion connection. The motor's drive shaft is connected to a connecting rod 9, which is made of stainless steel, 3 cm long, and 0.3 cm in diameter. One end of the connecting rod 9 is connected to the motor drive shaft via a coupling, and the other end is connected to the connecting head 6 via a pin. The connection between the connecting rod 9 and the connecting head 6 forms a crank-slider mechanism, converting the rotational motion of the motor into the linear reciprocating motion of the connecting rod 7.

[0022] Understandably, the disk body 1 also houses a battery. This battery is a lithium-ion rechargeable battery with a voltage of 3.7V and a capacity of 2000mAh, sufficient to support the drive device 10 for 8 hours of continuous operation. The battery is connected to the motor via wires wrapped with insulating material to prevent short circuits and leakage. The battery is fixed in a specially designed battery compartment inside the disk body 1, located on one side of the disk body 1 and isolated from the gap 8 to prevent moisture from affecting the battery. A charging port 11 is located on the outer surface of the disk body 1, connecting to the battery. The charging port 11 uses a standard Micro USB interface, located on the side of the disk body 1 for easy charger connection. A waterproof sealing ring surrounds the charging port 11 to prevent moisture from seeping into the disk body 1. An indicator light is located next to the charging port 11 to display the battery charging status and charge level. A control button is also located on the outside of the disk body 1, connected to the motor circuit, used to control the motor's start / stop and operating mode. The control button is made of waterproof silicone and has clearly marked function labels.

[0023] The working principle of this embodiment is as follows: The contact lens is placed in the first slot 2, and an appropriate amount of hydrating liquid is added. The contact lens is immersed in the liquid for hydration. When it is necessary to remove the contact lens, the control button is pressed, the motor starts, and the connecting rod 9 drives the connecting rod 7 to move on the moving track 5. The connecting rod 7 drives the top rod 4 to move up and down in the second slot 3. The top rod 4 pushes the contact lens in the first slot 2 upwards, so that part of the contact lens is exposed above the liquid surface, making it easier for automated equipment or manual handling. After removing the contact lens, the control button is pressed again, and the top rod 4 returns to its initial position, completing one operation cycle.

[0024] The beneficial effects of this embodiment are as follows: By setting a drive device 10 and a lifting mechanism inside the disc body 1, the automatic lifting function of contact lenses is realized, which facilitates precise grasping by automated equipment, improving production efficiency and accuracy. At the same time, the battery-powered and rechargeable design makes the device highly portable and practical. The design of the first slot 2 and the second slot 3 ensures the stability of contact lenses during the hydration process and the safety during the removal process.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
