Description

Technical Field

[0001] This invention relates to a device for enhancing the wear resistance of coating layers on optical glass lenses, and pertains to the field of optical glass lens surface treatment technology. Background Technology

[0002] Optical glass lenses are widely used in optical instruments, camera equipment, security monitoring, consumer electronics, and other fields. To improve the light transmittance, scratch resistance, abrasion resistance, and environmental tolerance of the lenses, functional abrasion-resistant reinforcing films are usually deposited on the lens surface. Magnetron sputtering coating has become the mainstream process for abrasion-resistant reinforcing coating of optical lenses due to its advantages such as good film density, strong adhesion, uniform thickness, and low film formation temperature. However, the lens clamping stability, coating angle controllability, tooling adaptability, and cavity environment stability during the coating process are the core factors determining the abrasion resistance performance and batch consistency of the coating layer.

[0003] For example, the existing patent CN120138589A discloses a substrate clamping device and method for a magnetron sputtering system. By setting four sets of clamping plates around the substrate, and providing a first rotation mechanism for driving the clamping plates to rotate longitudinally, a lateral adjustment mechanism for adjusting the clamping spacing, a longitudinal adjustment mechanism for adjusting the coating spacing, and a second rotation mechanism for driving the substrate to rotate laterally as a whole, the uniformity of multi-sided coating of the substrate can be optimized, the operation steps of changing the substrate to a certain extent are simplified, and the coating processing efficiency of a single substrate is improved.

[0004] However, this solution uses a four-sided opposing clamping structure, with the clamping force distributed linearly in opposite directions. This makes it impossible to achieve coaxial centering clamping of circular optical glass lenses, resulting in uneven clamping force distribution. Optical glass lenses are brittle materials, and during the coating process, they are prone to displacement, warping, and even edge chipping, failing to meet the high-precision clamping requirements for optical glass lens coating. Furthermore, the device lacks sufficient specification adaptability and batch processing capacity, making it impossible to achieve 360° continuous online rotation adjustment of the lens around the horizontal axis. If multi-angle coating is required, the coating process must be frequently interrupted, preventing continuous coating operations and easily disrupting the vacuum environment of the cavity. This leads to a decrease in film density and adhesion, directly affecting the wear resistance and quality stability of the coating layer. Additionally, the clamping mechanism, rotation, and adjustment mechanism of this device are integrated into a single design, making it impossible to quickly disassemble and replace the supporting tooling. For different batches and specifications of optical lenses, it is impossible to quickly switch to suitable clamping tooling. Moreover, the integrated structure makes internal cleaning and maintenance difficult, and residual impurities can easily affect the film formation quality, failing to meet the high cleanliness requirements of optical coating. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a device for enhancing the wear resistance of the coating layer on optical glass lenses.

[0017] The bottom center of the truncated cone has a positioning hole that matches the sleeve. The inner cavity of the sleeve is threaded with a threaded rod. The top of the threaded rod is fixed with a tapered column. The tapered surface of the tapered column abuts against the side wall of all the limiting blocks facing the inner cavity of the sleeve.

[0018] Preferably, each of the through holes is laterally fixed with a limiting post, the limiting post passing through the corresponding limiting block, and the limiting block is laterally provided with a stroke hole four that slides with the limiting post. The inner sidewall of the stroke hole four is fixedly connected with a spring two, and the free end of the spring two abuts against the outer wall of the limiting post.

[0019] The bottom end of the threaded rod extends to the bottom of the tray, and a knob is fixedly provided at the bottom end of the threaded rod.

[0020] Preferably, the installation mechanism includes two sets of supports symmetrically arranged around the center of the tray, with a base plate slidably connected to the bottom of the two sets of supports, and two sets of symmetrical slide rails fixedly provided on the top surface of the base plate, with the two sets of supports slidingly engaging with the corresponding slide rails respectively.

[0021] Both sets of supports are fixedly provided with L-shaped brackets on the same side, and a horizontally arranged hydraulic cylinder is connected between the two sets of L-shaped brackets. The hydraulic cylinder is used to drive the two sets of supports to move in opposite directions or away from each other along the slide rail.

[0022] Preferably, the steering mechanism includes a second rotating shaft that is rotatably connected to the top of the support. The second rotating shaft is arranged in a horizontal direction. A rectangular plate is fixedly provided at one end of each of the two sets of the second rotating shafts that are close to each other. The side of each set of the rectangular plates that are close to each other abuts against the outer wall of the tray.

[0023] One of the supports is equipped with a motor, and the output shaft of the motor is connected to the corresponding rotating shaft two for driving the rotating shaft two to rotate.

[0028] The beneficial effects of this invention are:

[0029] By setting up a surrounding linkage clamping mechanism, coaxial centering clamping of optical glass lenses can be achieved, with uniform clamping force distribution, effectively preventing displacement, warping, or edge chipping during lens coating. At the same time, clamping and unlocking can be completed by holding the adjustment handle with one hand, making operation simple and quick. It can be adapted to lenses of different diameters and has strong versatility. The pre-tightening locking structure of spring one can prevent loosening of the clamping during coating, ensuring the stability of lens clamping and laying the foundation for uniform coating and improved wear resistance.

[0030] The cone-column linkage locking mechanism enables quick and detachable connection between the frustum and the tray. Locking and unlocking can be completed by turning the knob. The frustum is easy to disassemble and replace. The corresponding tooling can be quickly switched according to the specifications of different batches of lenses, which is highly adaptable. At the same time, it facilitates the maintenance and cleaning of the cavity, ensuring the cleanliness of the coating environment and avoiding impurities from affecting the quality of film formation.

[0031] By coordinating the mounting and steering mechanisms, the tray can be quickly clamped and positioned. Simultaneously, the motor drives the tray, frustum, and lens to rotate continuously 360° around the horizontal axis, allowing for online adjustment of the lens's coating angle and coating surface. This eliminates the need to stop the machine to open the cavity and flip the lens, enabling multi-angle wear-resistant coating. This avoids repeatedly opening the cavity and disrupting the vacuum environment, ensuring the density and adhesion of the coating layer, significantly improving the wear resistance and uniformity of the coating layer, and greatly increasing the coating process efficiency.

[0032] The moving mechanism enables automatic loading and unloading of lenses, eliminating the need for manual insertion into the cavity and improving operational convenience and safety. Combined with the hydraulically driven lifting door structure, the opening and closing process occupies little space and has high positioning accuracy, effectively ensuring the vacuum sealing of the working chamber and providing a stable film formation environment for magnetron sputtering coating, further ensuring the batch stability of the wear resistance of the lens coating layer.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Please see Figure 1-17 The present invention provides a technical solution for an optical glass lens coating layer wear resistance enhancement treatment device, including a base 1, a working box 2 and a magnetron 3. The working box 2 is fixedly disposed on the top of the base 1. The working box 2 is a cavity structure with a side opening. The magnetron 3 is fixedly installed on the top of the inner cavity of the working box 2.

[0054] The working chamber 2 is a vacuum-sealed cavity, equipped with a vacuum unit (not shown in the figure) to provide a high vacuum environment for magnetron sputtering coating; the magnetron 3 is the core component of magnetron sputtering coating, equipped with a coating target, and is used to deposit a wear-resistant and strengthening film layer on the surface of optical glass lens by magnetron sputtering. The working principle of the vacuum unit and the magnetron 3 is a mature existing technology in the field of optical coating, and will not be described in detail here.

[0055] In the inner cavity of the working box 2, below the magnetron 3, there is a frustum 4. The top surface of the frustum 4 is surrounded by at least one placement cavity 5 for placing optical glass lenses. Each placement cavity 5 is provided with a clamping mechanism for clamping and fixing the optical glass lenses.

[0056] There are four placement cavities 5, which are evenly distributed in a ring on the top surface of the frustum 4. They can simultaneously perform coating treatment on four optical glass lenses, improving batch processing efficiency. In practical applications, the number of placement cavities 5 can be flexibly adjusted according to equipment specifications and production needs.

[0057] A tray 6 is provided below the frustum 4, and the tray 6 is detachably connected to the frustum 4 by a locking mechanism;

[0058] The work box 2 is also provided with an installation mechanism for carrying the pallet 6. The bottom of the installation mechanism is provided with a moving mechanism that is slidably connected to the bottom of the inner cavity of the work box 2. The installation mechanism is provided with a steering mechanism for driving the pallet 6 to rotate around a horizontal axis.

[0059] The side opening of the work box 2 is slidably connected to a box door 7 for closing the opening.

[0060] See Figure 1-17The clamping mechanism includes a circular shell 8 coaxially arranged with the placement cavity 5. A through hole 9 with a diameter adapted to the placement cavity 5 is opened in the middle of the circular shell 8. The through hole 9 communicates with the internal cavity of the circular shell 8. At least three clamping plates 10 are evenly arranged around the bottom of the circular shell 8 with the center of the through hole 9 as the axis. The clamping plates 10 have a petal-shaped structure. The side corner of the clamping plate 10 near the through hole 9 is rotatably connected to the circular shell 8 through a fixed shaft 11. The side corner of the clamping plate 10 away from the through hole 9 is rotatably connected to an arc-shaped rod 12 inclined towards the through hole 9. The free end of the arc-shaped rod 12 is movably connected to a rotating ring 14 through a rotating shaft 13. All the rotating shafts 13 corresponding to the arc-shaped rods 12 are movably connected to the same rotating ring 14. The rotating ring 14 is rotatably connected to the circular shell 8 on the same axis. An adjustment handle 15 extending to the outside of the circular shell 8 is fixedly provided on one side of the rotating ring 14.

[0061] The arc-shaped rod 12 is rotatably connected to the clamping plate 10 via a movable shaft 16, and the rotating ring 14 is provided with a stroke hole 17 that is adapted to the movable shaft 16 and allows the movable shaft 16 to move.

[0062] The outer walls of the circular shell 8 and the frustum 4 are respectively provided with stroke holes 2 18 for the adjustment handle 15 to move. A spring 19 is fixedly provided on the inner side wall of the stroke hole 2 18, and the free end of the spring 19 is fixedly connected to the side wall of the adjustment handle 15.

[0063] The circular shell 8 is fixedly connected to multiple positioning shafts 20 that are distributed around the center of the through hole 9. The positioning shafts 20 axially penetrate the rotating ring 14, and the rotating ring 14 is provided with a stroke hole 21 that slides with the positioning shafts 20.

[0064] When clamping the lens, move the adjusting handle 15 along the travel hole 18 to overcome the elastic force of the spring 19 and drive the rotating ring 14 to rotate around its axis. When the rotating ring 14 rotates, it drives all the arc rods 12 to swing synchronously through the rotating shaft 13. The arc rods 12 pull the clamping plates 10 around the fixed shaft 11 in the direction away from the through hole 9 through the movable shaft 16, so that the clamping ends of all the clamping plates 10 open synchronously. At this time, put the optical glass lens into the placement cavity 5 through the through hole 9, release the adjusting handle 15, and under the elastic force of the spring 19, the adjusting handle 15 drives the rotating ring 14 to rotate in the opposite direction. Then, through the arc rods 12, it pushes the clamping plates 10 to rotate around the fixed shaft 11 in the direction of the through hole 9. The clamping ends of all the clamping plates 10 close synchronously, and the edge of the optical glass lens is coaxially centered and clamped.

[0065] See Figure 1-17The locking mechanism includes a sleeve 22 fixedly disposed on the top surface of the tray 6 and coaxially disposed with the tray 6. The sleeve 22 has a hollow structure. Multiple through holes 24 are provided around the side wall of the sleeve 22. Each through hole 24 is movably provided with a limiting block 23 that can extend to the outside of the sleeve 22. The end face of the limiting block 23 facing the outside of the sleeve 22 is a wave-shaped limiting surface.

[0066] The bottom center of the truncated cone 4 is provided with a positioning hole 40 that is adapted to the sleeve 22. The inner cavity of the sleeve 22 is threadedly connected to a threaded rod 25. The top end of the threaded rod 25 is fixedly provided with a tapered column 26. The tapered surface of the tapered column 26 abuts against the side wall of all the limiting blocks 23 facing the inner cavity of the sleeve 22.

[0067] Each of the through holes 24 is laterally fixed with a limiting post 27, the limiting post 27 passes through the corresponding limiting block 23, the limiting block 23 is laterally provided with a stroke hole 28 that slides with the limiting post 27, the inner side wall of the stroke hole 28 is fixedly connected with a spring 2, and the free end of the spring 2 abuts against the outer wall of the limiting post 27.

[0068] The bottom end of the threaded rod 25 extends to the bottom of the tray 6, and a knob 29 is fixedly provided at the bottom end of the threaded rod 25.

[0069] When assembling the frustum 4, align the positioning hole 40 at the bottom of the frustum 4 with the sleeve 22 on the tray 6, and fully insert the sleeve 22 into the positioning hole 40; turn the knob 29 to drive the threaded rod 25 to rotate, and the threaded rod 25 engages with the internal thread of the sleeve 22, causing the cone 26 to move upward; during the upward movement of the cone 26, its conical surface pushes all the limiting blocks 23 to overcome the elastic force of the second spring and slide along the limiting post 27 towards the outside of the sleeve 22, so that the wave-shaped limiting surface of the limiting block 23 is in close contact with the inner wall of the positioning hole 40, forming a radial interference fit, thereby locking and fixing the frustum 4 and the tray 6.

[0070] When disassembling the frustum 4, turn the knob 29 in the opposite direction to move the threaded rod 25 and the cone 26 downwards. The resistance of the cone 26 to the limiting block 23 disappears. Under the restoring force of the spring 2, the limiting block 23 slides back into the inner cavity of the sleeve 22 and disengages from the inner wall of the positioning hole 40. The frustum 4 can then be removed from the tray 6 to complete the tooling replacement.

[0071] See Figure 1-17 The installation mechanism includes two sets of supports 30 symmetrically arranged with the center of the tray 6 as the axis. The bottom of the two sets of supports 30 is slidably connected to a base plate 31. The top surface of the base plate 31 is fixedly provided with two sets of symmetrical slide rails 32. The two sets of supports 30 are respectively slidably engaged with the corresponding slide rails 32.

[0072] Both sets of supports 30 are fixedly provided with L-shaped brackets 33 on the same side, and a horizontally arranged hydraulic cylinder 34 is connected between the two sets of L-shaped brackets 33. The hydraulic cylinder 34 is used to drive the two sets of supports 30 to move towards or away from each other along the slide rail 32.

[0073] When fixing the pallet 6, place the pallet 6 between the two sets of rectangular plates 36, activate the hydraulic cylinder 34, extend the piston rod of the hydraulic cylinder 34, drive the two sets of supports 30 to move towards each other along the slide rail 32, so that the two sets of rectangular plates 36 are close to each other until the inserts 38 on the rectangular plates 36 are fully inserted into the slots 39 on the side wall of the pallet 6, thus completing the clamping and fixing of the pallet 6; when it is necessary to remove the pallet 6, retract the piston rod of the hydraulic cylinder 34, drive the two sets of supports 30 to move away from each other, disengage the inserts 38 from the slots 39, and then remove the pallet 6.

[0074] See Figure 1-17 The steering mechanism includes a second rotating shaft 35 rotatably connected to the top of the support 30. The second rotating shaft 35 is arranged in a horizontal direction. A rectangular plate 36 is fixedly provided at one end of each set of the second rotating shafts 35 that are close to each other. The side of each set of the rectangular plates 36 that are close to each other abuts against the outer wall of the tray 6.

[0075] One of the supports 30 is fixedly equipped with a motor 37, and the output shaft of the motor 37 is connected to the corresponding rotating shaft 35 for driving the rotating shaft 35 to rotate.

[0076] When the coating angle of the lens needs to be adjusted, the motor 37 is started. The motor 37 drives the rotating shaft 35 to rotate, which in turn drives the tray 6, the frustum 4 and the entire lens to rotate around the axis (horizontal axis) of the rotating shaft 35 through the rectangular plate 36. This allows for 360° continuous rotation, online adjustment of the coating angle and coating surface of the lens, and uniform coating of both sides and multiple angles of the lens can be completed without stopping the machine to open the cavity and flip the lens.

[0077] Both sets of rectangular plates 36 have symmetrically arranged inserts 38 fixed on their sides that are close to each other, and slots 39 that are adapted to the inserts 38 are opened on the outer walls of both sides of the tray 6.

[0078] By inserting the pin 38 and the slot 39, the tray 6 is precisely positioned and circumferentially limited, ensuring that the tray 6 will not slip or deviate during the turning process, thus improving the accuracy of angle adjustment.

[0079] See Figure 1-17The moving mechanism includes a moving plate 41 fixedly mounted on the bottom of the base plate 31. Sliders are symmetrically arranged on both sides of the bottom of the moving plate 41. A slide rail 42 that slides and cooperates with the sliders is fixedly mounted on the bottom of the inner cavity of the working box 2. An electric telescopic rod is fixedly mounted at the middle of the bottom end of the inner cavity of the working box 2. The telescopic end of the electric telescopic rod is fixedly connected to the moving plate 41 and is used to drive the moving plate 41 to move back and forth along the slide rail 42.

[0080] During loading and unloading operations, the telescopic end of the electric telescopic rod extends, driving the moving plate 41 to move along the slide rail 42 toward the side opening of the work box 2, thus sending the mounting mechanism, tray 6, and frustum 4 out of the cavity of the work box 2 as a whole, making it convenient for operators to perform operations such as clamping lenses and replacing frustum 4; after the operation is completed, the telescopic end of the electric telescopic rod retracts, driving the moving plate 41 to move along the slide rail 42 toward the inner cavity of the work box 2, sending the clamped lens to the coating station below the magnetron 3.

[0081] See Figure 1-17 The inner walls of the two sides of the working box 2 at the side opening are provided with sliding grooves 43 that slide with the box door 7. The top two sides of the box door 7 are rotatably connected with inclined movable rods 44. The free ends of the two sets of movable rods 44 are fixedly connected to a connecting shaft 45. The top of the working box 2 is fixedly provided with a bearing seat 46, and the connecting shaft 45 is rotatably connected to the bearing seat 46.

[0082] One end of the connecting shaft 45 is fixedly connected to a downwardly inclined connecting rod 47, and the free end of the connecting rod 47 is rotatably connected to a hydraulic rod 48. The other end of the hydraulic rod 48 is rotatably connected to the outer wall of the working box 2.

[0083] When the chamber door 7 is opened, the piston rod of the hydraulic rod 48 retracts, causing the connecting rod 47 to rotate downwards around the axis of the connecting shaft 45, which in turn causes the connecting shaft 45 to rotate. During the rotation of the connecting shaft 45, the movable rod 44 pulls the chamber door 7 to slide upwards along the slide groove 43, thus achieving automatic opening of the chamber door 7.
