Description

Technical Field

[0001] This utility model relates to the field of optical manufacturing and processing, and in particular to an anti-splash ink coating device for optical lenses. Background Technology

[0002] Optical lenses are transparent glass or plastic sheets used in optical instruments. Their main function is to form a clear image by refracting and reflecting light. In some precision optical instruments, if the outer edge of the lens is not treated, light may leak out, affecting image quality. Applying ink can effectively block this light, ensuring that light travels only along a designed path.

[0003] Traditional methods of applying ink to optical lenses rely primarily on manual operation and simple mechanical equipment. Typically, the operator fixes the lens to be inkned on a rotating table, which then rotates the lens. While rotating, the operator uses tweezers to hold a sponge, soaks it in ink material, and applies it along the outer edge of the lens, spreading ink along its circumference. However, due to the limited precision of manual control, it's difficult to maintain consistent ink thickness and uniformity, resulting in ink that is either too thick or too thin. If the ink is too thick, it may splatter onto other parts or the operator due to centrifugal force, creating a messy working environment. If the ink is too thin, a second application is required, increasing the operation time.

[0004] Therefore, there is a particular need for an optical lens splash-proof ink coating device to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of traditional optical lens ink coating methods that rely on manual operation and simple equipment, such as rotating the optical lens by rotating the table and applying ink with a sponge, which suffers from uneven ink thickness, easy splashing, and low efficiency due to limited manual control precision, this utility model provides an optical lens splash-proof ink coating device.

[0006] This utility model is achieved through the following technical approach: an optical lens splash-proof ink coating device, comprising a base, a first mounting plate, a motor, a rotating rod, a first suction cup, a centering component, a third mounting plate, a second electric push rod, a clamping plate, an ink coating roller, a connecting frame, and a second suction cup.

The rotating rod is fixedly connected to the output shaft of the motor. The first suction cup is fixedly connected to the upper end of the rotating rod. The centering component for centering the optical lens is disposed at the top of the base. The third mounting plate is fixedly connected to the rear center of the top of the base. The second electric push rod is inserted into the middle of the third mounting plate. The clamping plate is attached to the telescopic rod of the second electric push rod. The ink roller is rotatably connected to the inside of the clamping plate. Its outer ring is made of sponge material. The third electric push rod is installed at the middle left of the rear side of the top of the base. The connecting frame is fixed to the telescopic rod of the third electric push rod. The second suction cup, which is the same size as the first suction cup, is rotatably connected to the front side of the upper part of the connecting frame and is located directly above the first suction cup. The first suction cup and the second suction cup are in an opposing state. It also includes a protective component to block the ink material. The protective component is set between the base and the connecting frame.

[0007] Furthermore, the protective assembly includes top rods, top plates, support plates, a rotating shaft, guide rods, a second spring, a connecting plate, and a protective cover. Two top rods are symmetrically distributed and fixed to the upper left and right sides of the connecting frame. Two support plates are symmetrically distributed and fixed to the upper rear side of the base. The rotating shaft is rotatably connected between the two support plates. Two top plates are symmetrically distributed and rotatably connected to the left and right ends of the rotating shaft. The two top rods correspond one-to-one with the two top plates. Two guide rods are symmetrically distributed and fixed to the upper rear side of the base. The connecting plate is slidably connected between the two guide rods. The top plate is located below the connecting plate, and its top end contacts the bottom end of the connecting plate. The second spring is sleeved on the outside of the guide rods, and its two ends are fixedly connected to the base and the connecting plate, respectively. The protective cover is fixed to the front of the connecting plate, and its rear has an opening to accommodate the card plate and the ink coating roller. The length of the opening is greater than the total length of the card plate and the ink coating roller, and there is a material storage area at the bottom of the protective cover.

[0008] Furthermore, the centering component includes a second mounting plate, a first electric push rod, a connecting block, a first spring, and a centering plate. Multiple second mounting plates are distributed left and right, fixed to the left and right sides of the top of the base, and three second mounting plates form a group. Each first electric push rod is mounted on each group of second mounting plates. The connecting block is fixed to the telescopic rod of the first electric push rod. The centering plate is slidably connected to the outside of the connecting block. It has multiple protrusions on the side facing the first suction cup, and the centering plate has a V-shaped design. The first spring for buffering and resetting is fixed between the connecting block and the centering plate.

[0009] Furthermore, it also includes a guide post, which is fixed to the rear right side of the top of the base. Its upper end passes through the connecting frame and slides in contact with it, and the limiting block at the top is located above the connecting frame.

[0010] Furthermore, it also includes a leak outlet, which is fixed to the lower left part of the protective cover. Its top end penetrates into the inside of the protective cover and is flush with the bottom of the inner side of the protective cover. There is a threaded ring at the lower outer diameter of the leak outlet.

[0011] Furthermore, the diameter of the bottom end of the guide rod is larger than the diameter of its main body.

[0012] Furthermore, the first suction cup is made of hard rubber, while the second suction cup is made of soft rubber.

[0013] Beneficial effects:

[0014] This invention automates the ink coating process through the coordinated operation of the second electric push rod, the clamping plate, and the ink coating roller, ensuring the thickness and uniformity of the ink coating and avoiding inconsistencies caused by manual operation. At the same time, through the protective components, the protective cover can completely cover the ink coating area during the ink coating process, effectively preventing the ink material from splashing around, protecting the safety of the operator, and maintaining a clean working environment.

[0015] This invention uses a central component to ensure that the optical lens remains in the center during the ink coating process, avoiding uneven ink coating caused by eccentricity and further improving the quality and consistency of ink coating. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example: An optical lens splash-proof ink coating device, such as Figures 1-4 As shown, the assembly includes a base 1, a first mounting plate 2, a motor 3, a rotating rod 4, a first suction cup 5, a centering component, a third mounting plate 11, a second electric push rod 12, a clamping plate 121, an ink coating roller 13, a third electric push rod 14, a guide post 141, a connecting frame 15, and a second suction cup 17. The first mounting plate 2 is welded to the lower front center of the base 1. The motor 3 is bolted to the middle of the first mounting plate 2. The rotating rod 4 is connected to the output shaft of the motor 3 via a coupling. The first suction cup 5 is glued to the upper end of the rotating rod 4 for optical centering. The lens centering component is located at the top of the base 1. The third mounting plate 11 is welded to the center of the rear side of the top of the base 1. The second electric push rod 12 is bolted to the middle of the third mounting plate 11. The clamping plate 121 is clamped to the telescopic rod of the second electric push rod 12 for easy disassembly. The ink roller 13 is rotatably connected to the inside of the clamping plate 121. Its outer ring is made of sponge material, which can effectively absorb ink material. The third electric push rod 14 is bolted to the center-left position of the rear side of the top of the base 1. The connecting frame 15 is welded to the third electric push rod 12. On the telescopic rod of rod 14, guide post 141 is welded to the top rear right side of base 1. Its upper end passes through connecting frame 15 and slides in contact with it. The limiting block at the top is located above connecting frame 15, which can effectively prevent connecting frame 15 from coming off the guide post 141. Second suction cup 17, which is the same size as the first suction cup 5, is rotatably connected to the upper front side of connecting frame 15 and is located directly above the first suction cup 5. The first suction cup 5 and the second suction cup 17 are in an opposing state and can respectively adsorb the upper and lower surfaces of the optical lens. The first suction cup 5 is made of hard rubber and has strong suction. It can firmly fix the optical lens. The second suction cup 17 is made of soft rubber and has relatively weak suction. It is mainly used to assist in fixing the optical lens. When the telescopic rod of the third electric push rod 14 retracts and drives the second suction cup 17 to move down, the second suction cup 17 approaches the first suction cup 5 and fixes the optical lens from the top and bottom. When the second suction cup 17 is detached from the optical lens, the suction of the first suction cup 5 is significantly greater than that of the second suction cup 17, ensuring that the optical lens stays firmly on the first suction cup 5. It also includes a protective component to block the ink coating material, which is set between the base 1 and the connecting frame 15.

[0023] like Figures 3-4As shown, the protective assembly includes top rods 16, top plates 18, support plates 19, a rotating shaft 20, guide rods 21, a second spring 22, a connecting plate 23, a protective cover 24, and a leakage port 25. Two top rods 16 are symmetrically distributed and welded to the upper left and right sides of the connecting frame 15. Two support plates 19 are symmetrically distributed and welded to the upper rear side of the base 1. The rotating shaft 20 is rotatably connected between the two support plates 19. Two top plates 18 are symmetrically distributed and rotatably connected to the left and right ends of the rotating shaft 20. The two top rods 22... Rod 16 corresponds one-to-one with two top plates 18, enabling precise compression of the top plates 18 when the rod 16 moves downward. Two guide rods 21 are symmetrically distributed and connected to the upper rear side of the base 1 by welding. A connecting plate 23 is slidably connected between the two guide rods 21. The diameter of the bottom end of the guide rod 21 is larger than the diameter of its main body, which can limit the movement of the connecting plate 23 and prevent it from detaching from the guide rods 21. The top plate 18 is located below the connecting plate 23, with its top end in contact with the bottom end of the connecting plate 23. This allows the connecting plate 23 to tilt upwards when the top plate 18 rotates. The second spring 22 is sleeved on the outside of the guide rod 21, with its two ends fixedly connected to the base 1 and the connecting plate 23, respectively. The protective cover 24 is welded to the front of the connecting plate 23, and its rear has an opening to accommodate the card plate 121 and the ink coating roller 13. The length of this opening is greater than the total length of the card plate 121 and the ink coating roller 13, ensuring that the card plate 121 and the ink coating roller 13 can smoothly enter and complete the ink coating operation. The lower part of the protective cover 24 has a storage area for easy collection. The ink-splashing material is collected, and the drain port 25 is connected to the lower left part of the protective cover 24 by welding. Its top end penetrates into the interior of the protective cover 24 and is flush with the bottom of the inner end of the protective cover 24, which facilitates the discharge of ink-splashing material inside the storage area. There is a threaded ring at the outer diameter of the lower end of the drain port 25, which can be connected to a pipe with a threaded hole at the inner diameter, which facilitates the delivery of ink-splashing material discharged from the drain port 25. When the top rod 16 presses the top plate 18 to rotate, the top plate 18 tilts the connecting plate 23 to move upward, and the protective cover 24 moves upward with the connecting plate 23 to cover the optical lens.

[0024] like Figure 2As shown, the centering assembly includes a second mounting plate 6, a first electric push rod 7, a connecting block 8, a first spring 9, and a centering plate 10. Six second mounting plates 6 are distributed left and right, and are welded to the left and right sides of the top of the base 1. Every three second mounting plates 6 form a group. Each first electric push rod 7 is bolted to each group of second mounting plates 6. The connecting block 8 is welded to the telescopic rod of the first electric push rod 7. The centering plate 10 is slidably connected to the outside of the connecting block 8, and has multiple protrusions on the side facing the first suction cup 5. The protrusion is made of soft rubber, which can prevent the centering plate 10 from damaging the outer diameter edge of the optical lens. The centering plate 10 has a V-shaped design, which can provide a natural guiding effect, so that the optical lens can automatically slide to the center position when centered. The first spring 9, which is used for buffering and resetting, is connected between the connecting block 8 and the centering plate 10 by welding. When the telescopic rod of the first electric push rod 7 extends and drives the connecting block 8 to move in the direction of the first suction cup 5, the centering plate 10 moves in the direction of the first suction cup 5 along with the connecting block 8, thereby centering and aligning the optical lens.

[0025] First, the operator uses a tool (such as a quick-release suction cup rod) to gently place the optical lens to be coated with ink onto the first suction cup 5. At this time, the optical lens is not yet fixed by the first suction cup 5. Then, the first electric push rod 7 is activated, controlling its extension rod to extend to a suitable length, driving the connecting block 8 to move inward. The centering plate 10 moves inward along with the connecting block 8, contacting and centering the optical lens. During the centering process, the centering plate 10 is squeezed outward by the optical lens, and the first spring 9 is compressed accordingly, playing a buffering role and preventing the centering plate 10 from directly contacting the optical lens and causing damage. After centering is completed, the extension rod of the first electric push rod 7 is retracted, driving the connecting block 8 to move outward. The centering plate 10 moves outward along with the connecting block 8, detaching from the optical lens. Spring 9 then returns to its original state, causing the centering plate 10 to move outward. After the connecting block 8 resets, the first electric push rod 7 is closed. At this time, the optical lens is pressed down, causing it to be fixed by the first suction cup 5. Then, an injection device (such as a syringe or dropper) is used to drip ink material onto the ink roller 13 until the sponge on the outer ring of the ink roller 13 is fully wetted. Then, the third electric push rod 14 is activated, controlling its telescopic rod to retract to a suitable length, driving the connecting frame 15 and all its components to move downward until the second suction cup 17 contacts and adsorbs the optical lens. During this process, the top rod 16 moves downward together with the connecting frame 15, contacting and pressing the top plate 18 to rotate clockwise. When the top plate 18 rotates, it tilts the connecting plate 23, causing the protective cover 24 to move upward, so that the protective cover 24... The first suction cup 5, the second suction cup 17, and the optical lens are covered, and the second spring 22 is compressed accordingly. At this time, the second electric push rod 12 is activated, controlling its telescopic rod to extend to a suitable length, driving the clamping plate 121 to move forward until the ink coating roller 13 contacts the outer diameter edge of the optical lens. Finally, the motor 3 is activated, and its output shaft drives the rotating rod 4 to rotate clockwise. The rotating rod 4 then drives the first suction cup 5 to rotate, cooperating with the second suction cup 17 to drive the optical lens to rotate clockwise, continuously contacting the ink coating roller 13 for ink coating. During the ink coating process, the ink material splashing from the outer diameter edge of the optical lens is blocked by the protective cover 24 and flows into the storage area along the inner wall of the outermost layer of the protective cover 24, and then discharged from the drain port 25 into the pre-connected pipe, thereby realizing the ink coating material To reduce waste, after ink coating is completed, motor 3 is turned off, and the telescopic rod of the second electric push rod 12 is retracted, causing the clamping plate 121 to move backward and reset, so that the ink coating roller 13 is disengaged from the outer diameter edge of the optical lens. The second electric push rod 12 is then turned off, and the telescopic rod of the third electric push rod 14 is extended, causing the connecting frame 15 and all its components to move upward and reset, so that the second suction cup 17 is disengaged from the optical lens. During this process, the top rod 16 moves upward and resets together with the connecting frame 15, disengaging and no longer pressing the top plate 18, so that the top plate 18 is relieved of the force that prying the connecting plate 23. The second spring 22 then returns to its original state, causing the connecting plate 23 to move the protective cover 24 downward and reset. At the same time, the connecting plate 23 pushes the top plate 18 to rotate counterclockwise and reset.Close the third motorized push rod 14, and finally use a tool (such as a quick-release suction cup rod) to remove the optical lens from the first suction cup 5. This completes the entire ink coating process for the optical lens.
