Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically to an ink coating device for optical lens processing. Background Technology

[0002] In the precision machining of optical lenses, ink coating is an indispensable and crucial auxiliary process. Its core purpose is to protect non-optical surfaces from damage during subsequent processes such as grinding, polishing, cleaning, or coating. During operation, the areas requiring protection must be precisely masked according to the lens geometry and protection requirements. The quality of the ink coating directly affects the machining yield and final optical performance; an effective ink layer can significantly reduce defects such as scratches, chipping, and corrosion pits. This process is widely used in the manufacturing of lenses, prisms, filters, and optoelectronic wafers, and is a vital guarantee for ensuring the surface integrity and performance reliability of high-precision optical components. Its accuracy and reliability directly affect the quality and cost of the final product.

[0003] Optical lens ink coating typically involves manual placement using a suction pen or automated placement using a robotic arm, followed by ink coating. When placing the optical lens, it is usually fixed by a rotating suction cup, resulting in a single fixing point. Regardless of whether the fixing is done manually or mechanically, there will be some error. Spraying through a jet valve may cause uneven ink layering, and ink dripping may also occur during the coating process. Ink adhering to the part surface is difficult to clean. Therefore, we propose an ink coating device for optical lens processing. Utility Model Content

A sliding column three is fixedly connected between each pair of fixed seats in the same group. The lower ends of the extension rods located at the front end and the rear end are slidably connected to the outside of adjacent sliding columns three, so as to realize the left and right movement of the baffle.

[0009] Furthermore, the blocking mechanism also includes a guide plate and a guide rod. The guide rod is fixedly connected between the extension rods located on the same baffle. The left and right ends of the lower surface of the fixed plate are fixedly connected with guide plates that are symmetrically distributed front and back.

[0017] Please see Figure 1-2 This embodiment provides a technical solution: an ink coating device for optical lens processing, including a base 1, a fixing mechanism 6 and a shielding mechanism 8; Base 1: Four evenly distributed support columns 3 are fixedly connected to its upper end.

A distance measuring hole is opened on the left side of the lifting plate 4. The distance sensor 10 is cleaned and maintained regularly to ensure good distance measurement feedback. The distance sensor 10 is located at the upper end of the distance measuring hole. The distance sensor 10 corresponds to the vertical position of the lifting plate 4. The distance sensor 10 is bidirectionally electrically connected to the microcontroller 2. The distance sensor 10 detects the change in the distance between itself and the lifting plate 4 and feeds it back to the microcontroller 2 to achieve precise control of the lifting height of the lifting plate 4, while avoiding interference between the parts of the lifting plate 4 and the fixed plate 5. The ink coating mechanism 7 includes an injection valve 71, a slide block 72, a servo push rod 73, two sliding columns 74, and a mounting base 75. The mounting base 75 is fixedly connected to the rear side of the upper surface of the base 1. Two sliding columns 74 are symmetrically distributed on the left and right sides and are fixedly connected to the top wall of the mounting base 75. The slide block 72 is slidably connected between the two sliding columns 74. The injection valve 71 is fixedly connected to the lower surface of the slide block 72. The servo push rod 73 is fixedly connected to the middle of the top wall of the mounting base 75. The front end of the guide rod of the servo push rod 73 is fixedly connected to the rear side of the slide block 72. The input ends of the servo push rod 73 and the jet valve 71 are both electrically connected to the output end of the microcontroller 2. After the optical lens is in place, the guide rod of the servo push rod 73 pushes the slide block 72 to slide between the two slide columns 74, realizing the back and forth movement of the jet valve 71. At the same time, the drive motor of the rotating vacuum chuck 64 drives the chuck and the optical lens to rotate. The back and forth movement of the jet valve 71 is controlled by the path program built into the microcontroller 2, so that the distance between the nozzle of the jet valve 71 and the ink coating position of the optical lens is consistent, and the ink coating is uniform. Fixing mechanism 6 includes a sliding column 61, a positioning seat 62, a slider 63, and a rotating vacuum suction cup 64. The drive motor of the rotating vacuum suction cup 64 is fixedly connected to the lower surface of the lifting plate 4. The suction cup of the rotating vacuum suction cup 64 passes through the through hole in the middle of the fixing plate 5. Sliding columns 61 are symmetrically distributed on both the left and right ends of the lower surface of the fixing plate 5. Sliding blocks 63 are slidably connected to the front and rear ends of the two sliding columns 61 on the same side. Positioning seats 62 are fixedly connected to the sides of the sliders 63 near the rotating vacuum suction cup 64. The middle of the fixing plate 5 has evenly distributed grooves. The upper ends of the positioning seats 62 are slidably connected to the adjacent grooves of the fixing plate 5. The air inlet of the rotating vacuum suction cup 64 is connected to an external air pump. The worker or robotic arm places the sample optical lens onto the upper end of the suction cup of the rotating vacuum suction cup 64, loosens the bolts fixing the slider 63, and the end of the slider 63 away from the rotating vacuum suction cup 64 has openings. The device has clamping grooves. By pressing the clamping grooves with bolts, the slider 63 is fixed to the sliding column 61 that is away from the rotating vacuum chuck 64. The position of the four sliders 63 is adjusted to adjust the position of the positioning seat 62 so that the arc surface of the upper end of the positioning seat 62 is in contact with the edge of the sample optical lens. Then the bolts are tightened again to fix the position of the slider 63. In the initial position, the middle of the lower surface of the sample optical lens is located at the upper end of the suction cup of the rotating vacuum chuck 64. The lower surface edge of the sample optical lens is in contact with the upper surface of the step of the positioning seat 62, providing support for the four corners of the sample optical lens and facilitating positioning. When applying ink, the optical lens is placed on the upper end of the suction cup of the rotating vacuum chuck 64. The four positioning seats 62 position the edge of the optical lens to ensure that the fixed position of each optical lens is consistent. Then the external air pump connected to the rotating vacuum chuck 64 draws air, and the suction cup of the rotating vacuum chuck 64 forms a negative pressure to fix the optical lens. The shielding mechanism 8 includes baffles 85, which are respectively disposed on the left and right sides of the fixed plate 5. The shielding mechanism 8 also includes fixed seats 81 and extension rods 82. The extension rods 82 are respectively vertically and evenly disposed on the lower surface of the baffles 85. The left and right sides of the fixed plate 5 are provided with evenly distributed positioning grooves. The extension rods 82 are respectively slidably connected to the inside of the adjacent positioning grooves. The upper surface of the lifting plate 4 is fixedly connected with four sets of fixed seats 81 arranged in pairs and evenly distributed. Each pair of fixed seats 81 in the same group is fixedly connected with a sliding column 3. The lower ends of the extension rods 82 located at the front end and the rear end are respectively slidably connected to the outside of the adjacent sliding column 3. The shielding mechanism 8 also includes guide plates 83 and guide rods 84. The guide rods 84 are respectively fixedly connected between the extension rods 82 located on the same baffle 85. The lower surface of the fixed plate 5 is fixedly connected to the left and right ends of the guide plates 81. There are symmetrically distributed guide plates 83. Extension rods 82 are slidably connected between the guide grooves of the two guide plates 83 on the left and right sides respectively. When the lifting plate 4 is raised, the baffle 85, extension rod 82 and guide rod 84 rise synchronously. The guide rod 84 slides upward inside the guide groove of the guide plate 83. The movement trajectory is: upward → towards the direction of the rotating vacuum suction cup 64 → upward, which drives the baffle 85 to move synchronously, so that the baffle 85 is raised higher than the positioning seat 62 and then closes. When it begins to close, the rotating vacuum suction cup 64 drives the optical lens to a position higher than the baffle 85. After the two guide plates 83 are closed, only a round hole is left to avoid the suction cup of the rotating vacuum suction cup 64. When applying ink, the ink droplets fall onto the upper surface of the baffle 85. A plastic film can be pasted on the upper surface of the baffle 85. The plastic film can be removed and replaced with a new one each time it is used.

[0018] It also includes a microcontroller 2, which is located on the front side of the base 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply, and the input terminal of the rotating vacuum suction cup 64 drive motor is electrically connected to the output terminal of the microcontroller 2.

[0019] This includes a drive mechanism 9, which comprises a lower sleeve 91, an inner sleeve 92, a lead screw 93, an outer sleeve 94, and a motor 95. The motor 95 is fixedly connected to the left side of the upper surface of the fixed plate 5.

The lower surface of the lifting plate 4 is fixedly connected to the lower sleeve 91, and the lower end of the lead screw 93 is located inside the lower sleeve 91. The upper surface of the lifting plate 4 is fixedly connected to the inner sleeve 92, and the lower surface of the fixed plate 5 is fixedly connected to the outer sleeve 94. The outer arc surface is slidably connected to the inner arc surface of the outer sleeve 94. The upper end of the lead screw 93 is located inside the integral structure formed by the inner sleeve 92 and the outer sleeve 94. The input end of the motor 95 is electrically connected to the output end of the microcontroller 2. The motor 95 is started by the microcontroller 2. The output shaft of the motor 95 drives the lead screw 93 to rotate, which drives the lifting plate 4 to rise between the four pillars 3, and drives the rotating vacuum suction cup 64 to rise, lifting the optical lens upward. The lower end of the lead screw 93 is always located inside the lower sleeve 91. The inner sleeve 92 slides upward inside the outer sleeve 94 to achieve dust protection for the lead screw 93.

[0020] The working principle of the ink coating device for optical lens processing provided by this utility model is as follows: When using this ink coating device, the ink inlet of the jet valve 71 is connected to an external ink supply device. The external ink supply device supplies ink to the jet valve 71 by means of air pressure or diaphragm pump. The jet valve 71 is a piezoelectric jet valve. The principle of the jet valve 71 is: the deformation of the piezoelectric ceramic is precisely controlled by voltage → driving the high-frequency reciprocating motion of the impact pin → realizing the on-demand jetting of fluid. A worker or robotic arm places the sample optical lens onto the upper end of the rotating vacuum chuck 64. The bolts securing the sliders 63 are loosened. Each slider 63 has a clamping groove at its end away from the rotating vacuum chuck 64. The bolts press against these grooves, fixing the sliders 63 to the sliding post 61 away from the rotating vacuum chuck 64. The positions of the four sliders 63 are adjusted to adjust the position of the positioning seat 62, ensuring the upper arc surface of the positioning seat 62 aligns with the edge of the sample optical lens. The bolts are then tightened again to fix the sliders 63 in their initial positions. The lower surface of the sample optical lens is located at the upper end of the suction cup of the rotating vacuum chuck 64. The lower surface edge of the sample optical lens is respectively attached to the upper surface of the step of the positioning seat 62, providing support for the four corners of the sample optical lens and facilitating positioning. When applying ink later, the optical lens is placed on the upper end of the suction cup of the rotating vacuum chuck 64. The four positioning seats 62 position the edges of the optical lens to ensure that the fixed position of each optical lens is consistent. Then, the external air pump connected to the rotating vacuum chuck 64 draws air, and the suction cup of the rotating vacuum chuck 64 forms a negative pressure to fix the optical lens. Then, the microcontroller 2 starts the motor 95. The output shaft of the motor 95 drives the lead screw 93 to rotate, which drives the lifting plate 4 to rise between the four pillars 3, and drives the rotating vacuum suction cup 64 to rise, lifting the optical lens upward. The lower end of the lead screw 93 is always inside the lower sleeve 91, and the inner sleeve 92 slides upward inside the outer sleeve 94 to achieve dust protection for the lead screw 93. The distance sensor 10 detects the change in distance between itself and the lifting plate 4 and feeds it back to the microcontroller 2, so as to achieve precise control of the lifting height of the lifting plate 4 and avoid interference between the parts of the lifting plate 4 and the fixed plate 5. When the lifting plate 4 is raised, the baffle 85, extension rod 82 and guide rod 84 rise synchronously. The guide rod 84 slides upward inside the guide groove of the guide plate 83. The movement trajectory is: upward → towards the direction of the rotating vacuum suction cup 64 → upward, which drives the baffle 85 to move synchronously, so that the baffle 85 is raised higher than the positioning seat 62 and then closes. When it begins to close, the rotating vacuum suction cup 64 drives the optical lens to a position higher than the baffle 85. After the two guide plates 83 are closed, only a round hole is left to avoid the suction cup of the rotating vacuum suction cup 64. When applying ink, the ink droplets fall onto the upper surface of the baffle 85. A plastic film can be pasted on the upper surface of the baffle 85. The plastic film can be removed and replaced with a new one each time it is used. After the optical lens is in place, the guide rod of the servo push rod 73 pushes the slide block 72 to slide between the two slide columns 74, realizing the back-and-forth movement of the spray valve 71. At the same time, the drive motor of the rotating vacuum suction cup 64 drives the suction cup and the optical lens to rotate. The back-and-forth movement of the spray valve 71 is controlled by the path program built into the microcontroller 2, so that the distance between the nozzle of the spray valve 71 and the ink coating position of the optical lens is consistent, maintaining the uniformity of ink coating. At the same time, when it is necessary to coat the optical lens at different heights, the height of the optical lens is adjusted by controlling the movement of the lifting plate 4 through the motor 95, which facilitates ink coating. It is worth noting that the microcontroller 4 disclosed in the above embodiments can be a PIC16F1823-I / P model microcontroller, the rotary vacuum suction cup 64 can be a 35SMT40-503-30H6 rotary vacuum suction cup, the jet valve 71 can be a WZ-GSLV piezoelectric jet valve, the servo push rod 73 can be an MCE-3G servo electric motor, the ranging sensor 10 can be a KJT-TLS-30C-E1 laser ranging sensor, and the motor 95 can be freely configured according to the actual application scenario. The microcontroller 4 performs timing control of each process based on the feedback from the ranging sensor 10. The microcontroller 4 controls the operation of the rotary vacuum suction cup 64, the jet valve 71, the servo push rod 73, the ranging sensor 10, and the motor 95 using methods commonly used in the prior art.
