Description

Technical Field

[0001] This invention relates to the field of lens processing auxiliary technology, and more specifically to an auxiliary device for the production and processing of lens accessories. Background Technology

[0002] An optical lens is a composite imaging system precisely assembled from multiple precision optical lenses (such as convex lenses, concave lenses, and aspherical lenses), spacers, pressure rings, and lens barrels, according to a specific optical path design. Its core function is to focus the light signal from the subject onto the image sensor or film plane through the refraction and reflection of incident light by the lens group, forming a clear image with high resolution, low distortion, and high contrast. Optical lenses are widely used in consumer electronics (such as smartphones and digital cameras), security monitoring, industrial machine vision, medical endoscopic imaging, aerospace remote sensing, and other fields, and their image quality directly affects the performance of terminal equipment.

[0003] The manufacturing process of optical lenses is a high-precision optomechanical integrated processing, in which the processing of optical components is a key technological step. A typical processing flow includes: material preparation (blank cutting and shaping), rough grinding / milling (preliminary shaping), fine grinding (improving geometric accuracy), polishing (achieving nanoscale surface smoothness to form a high-quality optical surface), coating (deposition of functional thin films such as anti-reflection, beam splitting, and filtering), and post-processing steps such as ink coating.

[0004] Among these processes, the inking process is particularly important. Its purpose is to coat non-transparent areas such as the lens's edge surface, chamfered areas, and the inner wall of the lens barrel with a black, high-absorption, low-reflectivity functional coating. This coating is typically composed of epoxy or acrylic resin-based black ink, which cures to form a stable film. Its main function is to absorb stray light, preventing multiple reflections or scattering of light at the lens edge or inner wall of the lens barrel, thereby effectively suppressing optical defects such as ghosting and glare, and improving image contrast and signal-to-noise ratio.

[0005] For small, regularly circular optical lenses, traditional ink coating processes typically involve fixing the lens to a high-speed rotating fixture, with an operator manually manipulating an ink pen or dispensing head to evenly apply ink to the outer edge of the lens. However, this method has significant drawbacks: manual operation makes it difficult to guarantee the consistency of ink thickness, coverage, and uniformity, easily leading to problems such as missed areas, ink buildup, and uneven thickness, affecting product yield and optical performance stability.

[0006] Based on the above problems, there is an urgent need to provide an auxiliary device for the production and processing of lens accessories. Through mechanical assistance, the ink coating process can be precisely controlled and uniformly covered, ensuring the formation of a continuous, uniform, and controllable thickness black coating at the lens edge. This significantly improves the processing consistency, production efficiency, and product yield of the ink coating process, meeting the stringent requirements of high-end optical lenses for manufacturing precision and reliability. Summary of the Invention

[0009] Preferably, the sliding frame is provided with a control groove, a counterweight platform is provided in the control groove, a counterweight block is provided on the counterweight platform, a guide wheel is provided on the sliding frame, and a pull rope is provided between the counterweight platform and the control frame to realize the unpressurized state of the linear hydraulic damper at the beginning.

[0010] Preferably, an ink cartridge is mounted on the sliding frame, an ink cylinder is mounted on the sliding frame, a piston is mounted on the ink cylinder, a linear spring is mounted between the piston and the ink cylinder, the ink cylinder is connected to the ink storage chamber of the ink-dispensing pen tip through an ink supply pipe, and the ink cylinder is connected to the ink cartridge through a branch pipe to achieve automatic ink replenishment.

[0011] Preferably, the sliding frame is rotatably connected to a second connecting rod via a rotating rod. The second connecting rod has a guide groove, and the control frame has a support rod that slides in contact with the guide groove of the second connecting rod. A third connecting rod is hinged to the second connecting rod. A return spring is provided between the third connecting rod and the second connecting rod. The third connecting rod has a groove, and the piston has a crossbar that slides in contact with the groove of the third connecting rod. The automatic ink replenishment effect of the ink cartridge is achieved through the second connecting rod, the third connecting rod, and the crossbar.

[0012] Preferably, the mounting bracket is provided with a screw rod, which is threadedly connected to the mounting bracket. The screw rod is provided with a clamping bracket, which has an arched clamping surface to facilitate the disassembly, installation and stabilization of the ink-spreading pen.

[0013] Preferably, the sliding frame is provided with a mounting platform, and the mounting platform is provided with a screw rod 2. The screw rod 2 is connected to the mounting platform by a thread, and the screw rod 2 is provided with a positioning frame. The positioning frame is slidably connected to the mounting platform, and the upward travel of the connecting rod 3 is limited by the positioning frame.

[0014] Preferably, the rotating frame is provided with a ring frame, the rotating frame is provided with a guide frame, the guide frame is provided with several through slots, and each through slot is provided with a clamping block, which is used to center the lens on the vacuum suction cup.

[0015] Preferably, a rubber pad is provided on the rotating frame, a vacuum suction cup is slidably connected to the rotating frame, a connecting spring is provided between the vacuum suction cup and the rotating frame, the vacuum suction cup is centrally located in the inner ring area of ​​the rubber pad, and is connected to the vacuum pump through a gas guide tube, and the lens is supported by the rubber pad and the vacuum suction cup together.

[0018] Beneficial effects: Compared with existing technologies, this device, through the coordinated operation of the pull handle, control frame, mounting frame, and ink-spreading pen, provides stable and uniform damping force through a linear hydraulic damper, ensuring that the ink-spreading pen achieves uniform and precise control of the ink-spreading stroke. Under the combined action of the continuous rotation of the lens and the uniform downward movement of the ink-spreading pen, the black coating material is evenly coated on the side edge and chamfer area of ​​the lens, forming a low-reflection coating with consistent thickness and complete coverage. This effectively overcomes the defects of uneven coating, uncontrolled thickness, and edge omissions in manual ink-spreading, significantly improving the repeatability, consistency, and processing accuracy of the ink-spreading process. It meets the stringent requirements of high-precision optical lenses for stray light control and is suitable for the automated post-processing production of mass-produced lens accessories.

[0019] Through the linkage mechanism of the support rod, the guide groove of the second connecting rod, the second and third connecting rods, and the piston in the ink supply assembly, the vertical movement of the ink-spreading pen is converted into the volume change of the ink cartridge, realizing a synchronized and automated ink supply mechanism for ink application and replenishment. The ink replenishment process is precisely matched with the ink application stroke, avoiding insufficient ink or overflow, and ensuring the continuity, uniformity and process stability of edge ink application.

[0020] By using the mechanical linkage between the pressure ring and the clamping block to achieve centered clamping of the lens, and combining this with controllable vacuum adsorption, the problem of misalignment and inaccurate positioning when clamping small optical lenses is effectively solved.

Detailed Implementation

[0028] Next, combine Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0029] refer to Figure 1 and Figure 2 and Figure 4 An auxiliary device for the production and processing of lens accessories includes a worktable 1. A servo motor 13 is mounted at the center of the worktable 1. A rotating frame 12 is mounted on the output shaft of the servo motor 13 to achieve the rotation of the rotating frame 12. A vacuum suction cup 15 is mounted on the rotating frame 12 to stably adsorb small, regularly circular optical lenses and ensure that they maintain concentricity and posture stability during high-speed rotation. After being positioned, the lens to be processed is adsorbed and fixed by the suction cup 15 and rotates synchronously at high speed with the rotating frame 12 to form the circumferential motion reference required for ink application.

[0030] The side of the workbench 1 is provided with a straight slide groove arranged in the horizontal direction. A sliding frame 3 is slidably connected in the slide groove to support the ink application actuator. A linear hydraulic damper 31 is installed on the sliding frame 3, and a control frame 32 is fixedly connected to its top. The control frame 32 is detachably connected to a mounting frame 33 by bolts. An ink-spreading pen 35 is detachably connected to the mounting frame 33. Initially, the tip of the ink-spreading pen 35 is higher than the suction cup 15. By moving the tip of the ink-spreading pen 35 downward, it is precisely aligned with and contacts the outer edge surface of the lens adsorbed on the suction cup 15, and is used to perform ink application during the lens rotation. The control frame 32 is provided with a handle 39 for manual intervention and adjustment by the operator.

[0031] During operation, the lens to be coated with ink is placed on the suction cup 15 and fixed by adsorption. The sliding frame 3 is manually pushed along the slide groove to move to the preset limit position, so that the contact of the ink pen 35 is close to the edge of the lens. The rotating frame 12 and the servo motor 13 are started to drive the lens to rotate at high speed.

[0032] The operator pulls down the handle 39, which drives the mounting bracket 33 and the ink-spreading pen 35 to move downwards synchronously through the control frame 32. The linear hydraulic damper 31 provides a stable and uniform damping force to ensure that the ink-spreading pen 35 moves at a uniform speed during the descent, smoothly and without impact, thus achieving uniform and precise control of the ink-spreading stroke. Under the combined action of the continuous rotation of the lens and the uniform axial downward movement of the ink-spreading pen 35, the black coating material is evenly coated on the side edge and chamfer area of ​​the lens, forming a low-reflection coating with consistent thickness and complete coverage.

[0033] This device effectively overcomes the defects of manual ink application, such as uneven coating, uncontrolled thickness, and missing coating at the edges, by combining mechanical guidance with hydraulic damping control. It significantly improves the repeatability, consistency, and processing accuracy of the ink application process, meets the stringent requirements of high-precision optical lenses for stray light control, and is suitable for automated post-processing production of mass-produced lens accessories.

[0034] refer to Figure 4 The sliding frame 3 has a vertically arranged control groove 301 on its side wall. A counterweight platform 37 is embedded and slidably connected in the control groove 301. The counterweight platform 37 can reciprocate vertically along the control groove 301. An adjustable counterweight block 38 is installed on the counterweight platform 37 to adjust the balance of the device. A guide wheel 361 is rotatably connected to the top of the sliding frame 3. The counterweight platform 37 and the control frame 32 are connected by a pull rope 36. The pull rope 36 passes around the guide wheel 361 to achieve a change of direction transmission.

[0035] The function of the guide wheel 361 is to reduce the sliding friction resistance of the pull rope 36 during the movement and to precisely guide the direction of the pull rope 36, ensuring the smoothness and reliability of force transmission. Through the mechanical linkage and mechanical balance between the counterweight platform 37, counterweight block 38, pull rope 36 and control frame 32, the linear hydraulic damper 31 is in a free state without preload and does not bear additional pressure when the device is initially stationary.

[0036] By adjusting the mass of the counterweight 38, the counterweight platform 37 and the control frame 32, as well as the mounting frame 33 and the ink-spreading pen 35 it supports, form a static torque balance. This balancing mechanism effectively counteracts the influence of the actuator's own weight on the linear hydraulic damper 31, ensuring that the linear hydraulic damper 31 only responds to the active control force applied by the operator through the handle 39, thereby achieving smooth, controllable and precise adjustment of the ink-spreading pen 35's descent process.

[0037] After the ink application is completed, the force applied to the handle 39 is released. Under the weight of the counterweight platform 37 and the counterweight block 38, the control frame 32 is pulled upward by the pull rope 36, which drives the mounting frame 33 and the ink-spreading pen 35 it carries to move upward synchronously. The reset process is provided with controllable damping by the linear hydraulic damper 31 to ensure smooth and shock-free movement, so as to achieve uniform return reset of the ink-spreading pen 35 and accurately restore it to the initial standby position, so as to prepare for the next ink application operation.

[0038] To enable the ink-dispensing pen 35 to continuously and controllably replenish ink during the ink application process, and to ensure the continuity of the ink application operation and the uniformity of the coating, this device is equipped with an ink supply component on the side wall of the sliding frame 3.

[0039] refer to Figure 5 and Figure 6 The sliding frame 3 has an ink cartridge 4 installed on its side wall via a detachable connection. This cartridge stores ink and continuously supplies ink to the ink-distributing pen 35. The sliding frame 3 also has an ink cylinder 42 on its side wall. The ink cylinder 42 is a closed cylindrical cavity with an internal cavity. A piston 421 is embedded and slidably fitted inside the cavity. A linear spring 424 is provided between the end of the piston 421 located in the inner cavity of the ink cylinder 42 and the bottom of the ink cylinder 42 to provide a restoring force for the piston 421. The top of the ink cylinder 42 is connected to the ink storage cavity of the ink-distributing pen 35 through an ink supply pipe 41 to realize ink delivery. The bottom wall of the ink cylinder 42 is connected to the ink cartridge 4 via a branch pipe 423 to form an ink replenishment channel.

[0040] To achieve automated mechanical linkage between inking and re-inking actions, this device employs the following linkage drive structure: The left and right side walls of the sliding frame 3 are rotatably connected to connecting rod 43 via rotating rods 48. The free end of connecting rod 43 has an elongated guide groove. Support rods 49 are symmetrically fixed to the left and right side walls of the control frame 32. The two support rods 49 are slidably embedded into the guide grooves at the ends of adjacent connecting rods 43. Connecting rod 44 is hinged to connecting rod 43. A return spring 45 is provided between connecting rod 44 and connecting rod 43, ensuring that connecting rod 44 remains collinear with connecting rod 43 in an initial horizontal state when no external force is applied. The free end of connecting rod 44 has a groove.

[0041] refer to Figure 6 A crossbar 422 is fixedly connected to the bottom of the piston 421. The left and right ends of the crossbar 422 are slidably embedded into the grooves at the ends of the connecting rods 44 on both sides, forming a sliding fit connection to realize motion transmission.

[0042] In the initial state, the return spring 45 is in a relaxed state, the third connecting rod 44 and the second connecting rod 43 are collinear, and the ink storage chamber of the ink-spreading pen 35 is pre-filled with an appropriate amount of ink, ready for use.

[0043] When the ink application operation is started, the operator pulls down the handle 39, which moves the control frame 32, the mounting frame 33 and the ink-spreading pen 35 downwards simultaneously. During this process, the support rod 49 on the control frame 32 moves down and slides in the guide groove of the second connecting rod 43, pushing the bottom of the guide groove to exert a downward force on the second connecting rod 43, forcing the second connecting rod 43 to rotate around the rotating rod 48. At the same time, the return spring 45 is compressed. The elastic force of the return spring 45 drives the third connecting rod 44 to rotate around the hinge point of the second connecting rod 43, thus disengaging it from the collinear state.

[0044] During the rotation of the connecting rod 44, the groove at its end pushes the crossbar 422 upward, which in turn drives the piston 421 to move upward in the inner cavity of the ink cylinder 42. The linear spring 424 deforms, and the piston 421 moves upward, creating a negative pressure in the inner cavity of the ink cylinder 42. This causes the ink in the ink cartridge 4 to be drawn into the inner cavity of the ink cylinder 42 through the branch pipe 423. As the handle 39 continues to be pulled down, the piston 421 continues to move upward, compressing the air in the ink cylinder 42. When the pressure reaches the set value, the ink is forced into the ink storage cavity of the pen tip of the ink-equalizing pen 35 through the ink supply pipe 41, completing a quantitative ink replenishment.

[0045] After ink application, the control frame 32 moves upward during the reset process. Through mechanical linkage, it drives the support rod 49 to slide in the reverse direction within the guide groove of the connecting rod 43, forcing the connecting rod 43 to rotate in the opposite direction around its hinge point with the rotating rod 48. Simultaneously, the previously compressed and stored reset spring 45 begins to release its elastic potential energy, driving the connecting rod 44 to rotate in the opposite direction around its hinge point with the connecting rod 43. During the reverse rotation of the connecting rod 44, the groove structure at its end pushes the crossbar 422 downward, realizing the motion conversion. The crossbar 422 drives the piston 421 to move downward synchronously within the ink cylinder 42. The linear spring 424 is released and its deformation is restored. The downward movement of the piston 421 creates a negative pressure compensation and reflux channel within the ink cylinder 42, causing excess ink remaining in the ink cylinder 42 to flow back to the ink storage box 4 through the branch pipe 423. This completes the pressure balance and waste ink recovery of the ink system, preventing ink leakage or accumulation, ensuring the cleanliness and stability of the ink supply system, and improving the reliability of equipment operation and the repeatability of the process.

[0046] This structure, through the linkage mechanism of the support rod 49, the guide groove of the second connecting rod 43, the second connecting rod 43 and the third connecting rod 44, and the piston 421 in the ink supply assembly, converts the vertical movement of the ink-spreading pen 35 into the volume change of the ink cylinder 42, realizing a synchronized and automated ink supply mechanism for ink application and replenishment. The ink replenishment process is precisely matched with the ink application stroke, avoiding insufficient ink or overflow, and ensuring the continuity, uniformity and process stability of edge ink application.

[0047] The ink-spreading pen 35 used in this device is a replaceable design to adapt to different process requirements and achieve rapid maintenance. Specifically, the mounting bracket 33 is provided with a vertically arranged screw 34, which is threadedly connected to the mounting bracket 33. A retaining bracket 341 is threadedly connected to the screw 34, and the retaining bracket 341 is provided with an arched clamping surface designed to fit against the outer peripheral sidewall of the ink-spreading pen 35.

[0048] By applying external force to rotate screw 34, the clamping frame 341 can be driven to move axially, thereby adjusting the clamping distance between the clamping frame 341 and the mounting frame 33, enabling the rapid insertion, clamping, and release of the ink-spreading pen 35. This structure not only facilitates the replacement and maintenance of the ink-spreading pen 35, but also adapts to various diameter specifications of ink-spreading pens 35 by adjusting the screw 34's screw depth, possessing good versatility and size compatibility, and meeting the flexible production needs of ink coating processing for multiple varieties and small batches of optical components.

[0049] refer to Figure 5To accommodate the varying ink supply demands of different specifications of ink-dispensing pens 35 due to differences in ink storage capacity at the pen tip, this device is equipped with an adjustable ink supply limiting structure to achieve precise and on-demand ink replenishment of the ink supply component. Specifically, a mounting platform 471 is fixedly connected to the side wall of the sliding frame 3. A vertically arranged screw 47 is provided on the mounting platform 471, which is threadedly connected to the mounting platform 471. A positioning frame 46 is threadedly connected to the screw 47, and the bottom of the positioning frame 46 slides through and is slidably fitted onto the mounting platform 471. Driven by the screw 47, its installation height is precisely adjusted vertically. The positioning frame 46 is used to limit the maximum upward stroke of the connecting rod 44 during the linkage process.

[0050] In the initial stage, based on the ink storage capacity of the ink-spreading pen 35, the positioning frame 46 is adjusted to a preset height position by rotating the screw 47, thereby setting the end point of the ink replenishment stroke. When the operating handle 39 moves the control frame 32, the mounting frame 33, and the ink-spreading pen 35 downwards synchronously, the connecting rod 44 rotates and moves upwards under the drive of the linkage mechanism. When the end of the connecting rod 44 contacts the bottom of the positioning frame 46, the movement is blocked and stops moving upwards, thereby limiting the maximum stroke of the crossbar 422 and the piston 421. Finally, the negative pressure suction volume formed by the piston movement in the ink cylinder 42 is controlled, and the amount of ink replenished to the ink storage chamber of the ink-spreading pen 35 through the ink supply pipe 41 is precisely adjusted.

[0051] As the handle 39 continues to move downwards, link 3 44 stops moving under the limiting action of positioning bracket 46, while link 2 43 can continue to rotate around its axis, ensuring coordinated movement of the overall linkage mechanism and preventing structural interference. This design, through a mechanical stroke limiting mechanism, achieves graded or continuously adjustable ink supply, ensuring precise matching between ink supply and the actual needs of the pen tip, avoiding insufficient or excessive ink overflow, and improving the stability, controllability, and material utilization of the ink coating process.

[0052] refer to Figure 2 and Figure 3 A ring frame 23 is fixedly connected to the rotating frame 12, and a guide frame 2 is slidably connected to it. The guide frame 2 has several circumferentially evenly distributed through slots 201. Each through slot 201 has a clamping block 22 embedded and slidably connected within it. The clamping block 22 can move laterally along the through slot 201 to clamp and fix the edge of the optical lens adsorbed on the vacuum chuck 15. Through the synchronous lateral movement of multiple clamping blocks 22, automatic centering of the lens is achieved, improving the concentricity and process accuracy of the rotary ink coating.

[0053] A rubber pad 14 is provided on the top of the rotating frame 12. The rubber pad 14 is a ring structure used to support and buffer the bottom surface of the lens. The vacuum suction cup 15 is slidably connected to the rotating frame 12. A connecting spring is provided between the vacuum suction cup 15 and the rotating frame 12 for the reset of the vacuum suction cup 15. The vacuum suction cup 15 is centrally located in the inner ring area of ​​the rubber pad 14 and is connected to the vacuum pump through the air guide tube 16 to achieve controllable adsorption.

[0054] In the initial state, the adsorption surface of the vacuum suction cup 15 is slightly higher than the surface of the rubber pad 14. When the lens is placed on top of the vacuum suction cup 15, its own weight causes the vacuum suction cup 15 to move downward. The lens is supported by the rubber pad 14 and the vacuum suction cup 15 together, forming a stable support.

[0055] To enable the lateral movement of the clamping block 22, a pressure ring 21 is fixedly connected to the outer wall of the guide frame 2 to facilitate the application of external force. A connecting rod 24 corresponding to the through slot 201 is hinged to the ring frame 23 via a rotating shaft. The other end of the connecting rod 24 is hinged to the bottom of the adjacent clamping block 22 to form a linkage mechanism.

[0056] Initially, the clamping blocks 22 are located at the outermost position of the through groove 201. After the lens is placed on the vacuum suction cup 15, the vacuum suction cup 15 is pressed down, and the lens is supported by the rubber pad 14 and the vacuum suction cup 15. At this time, the pressure ring 21 is pulled upward, causing the guide frame 2 to move upward as a whole. Through the transmission action of the connecting rod 24, each clamping block 22 is pushed to move synchronously towards the center along the through groove 201, gradually approaching and finally contacting the outer edge of the lens. Under the uniform force applied by the multiple clamping blocks 22, the lens is automatically adjusted to the center position, achieving precise centering relative to the rubber pad 14 and the vacuum suction cup 15.

[0057] After centering is completed, the vacuum pump is started, and the vacuum suction cup 15 is evacuated through the air guide tube 16 to make the lens firmly attached to the surface of the vacuum suction cup 15, ensuring that it remains in a stable position during high-speed rotation. After that, the device enters the ink coating operation stage.

[0058] This structure effectively solves the problems of misalignment and inaccurate positioning when clamping small optical lenses by combining mechanical linkage centering clamping with controllable vacuum adsorption.

[0059] The workbench 1 has a receiving platform 11 on its side wall, which can be used to place the lens to be processed.
