Description

Technical Field

[0001] This utility model relates to the field of lens coating clamping technology, and in particular to a lens coating clamping device that facilitates multi-angle deflection. Background Technology

[0002] In the lens coating process, traditional clamping devices typically employ a vertical lifting structure to fix the lens and then send it into the coating chamber for coating deposition. The single vertical movement results in a fixed incident angle between the lens surface and the evaporation source of the coating material. This is especially problematic for curved or asymmetrical lenses, where uneven coating thickness and poor material adhesion are likely to occur at the edges, directly affecting optical performance. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lens coating clamping device that facilitates multi-angle deflection.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a lens coating clamping device that facilitates multi-angle deflection, comprising a column, a first sliding groove on the column, a lead screw rotatably disposed within the first sliding groove, a slider sleeved on the lead screw, a connecting plate fixedly connected to the slider, a ball-head column at the end of the connecting plate, a mounting base sleeved on the ball-head column, an electric gripper at the bottom end of the mounting base, and an offset component between the mounting base and the opposite surface of the column.

[0005] Preferably, the offset assembly includes an electric actuator, the top end of which is hinged to the mounting base, and the bottom end of which is fixedly connected to an arc-shaped slider.

[0006] Preferably, the arc-shaped slider is mounted on an arc-shaped guide rail, and the two ends of the arc-shaped guide rail are symmetrically provided with limiting plates, which are fixedly connected to both sides of the connecting plate.

[0007] Preferably, a second slide groove is symmetrically provided on both sides of the first slide groove, and a guide rod is provided in each of the second slide grooves. A protrusion extends from the limiting plate to engage with the guide rod.

[0008] Preferably, the arc-shaped guide rail has an I-shaped cross-section, a rack is provided on the inner wall of the arc-shaped guide rail, a gear is rotatably provided inside the arc-shaped slider, the gear meshes with the rack, a rotating shaft passes through the shaft of the gear, and a drive motor mounted on the outer wall of the arc-shaped slider is coaxially fixed to the rotating shaft.

[0009] Preferably, the lead screw is coaxially fixed to a first motor mounted on the outer wall of the top of the column, and the electric gripper is provided with multiple anti-slip rubber pads on its gripper.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model facilitates precise adjustment of lens height through the lifting and lowering cooperation of the lead screw and connecting plate, improving the positioning efficiency within the coating cavity. Furthermore, the hinged cooperation between the ball joint and the mounting base enables multi-degree-of-freedom deflection of the lens around the ball's center, thus adapting to different incident angle requirements. Further, the driving cooperation between the electric push rod and the arc-shaped slider facilitates dynamic adjustment of the offset between the mounting base and the column, improving the controllability of the lens's pitch or yaw angle. The meshing cooperation between the gear and the arc-shaped guide rail rack enables precise displacement of the arc-shaped slider along the guide rail, ensuring the stability and repeatability of angle adjustment. Finally, through multi-component collaborative control, it solves the problems of uneven film thickness and poor adhesion caused by the single coating angle in traditional straight-up-down structures. Simultaneously, it is compatible with efficient coating of curved and asymmetric lenses, significantly improving coating uniformity and process adaptability, and reducing the intensity of manual intervention.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4This utility model discloses a lens coating clamping device that facilitates multi-angle deflection. It includes a column 1 with a first groove. A lead screw 2 is rotatably mounted within the first groove. A slider is sleeved on the lead screw 2, and a connecting plate 3 is fixedly connected to the slider. A ball-head column 4 is located at the end of the connecting plate 3, and a mounting base 5 is sleeved on the ball-head column 4. An electric gripper 6 is located at the bottom of the mounting base 5. An offset assembly is provided between the opposing surfaces of the mounting base 5 and the column 1. The lead screw 2 drives the connecting plate 3 to rise and fall, achieving precise adjustment of the lens height. The hinged structure between the ball-head column 4 and the mounting base 5 provides a basis for multi-angle deflection. Overcoming vertical motion limitations, the offset component includes an electric actuator 7. The top of the telescopic rod of the electric actuator 7 is hinged to the mounting base 5, and an arc-shaped slider 8 is fixedly connected to the bottom end of the electric actuator 7. The electric actuator 7 pushes the arc-shaped slider 8 to move, dynamically controlling the deflection angle of the mounting base 5 to achieve automated pitch / yaw adjustment. The arc-shaped slider 8 is mounted on an arc-shaped guide rail 10. Limiting plates are symmetrically provided at both ends of the arc-shaped guide rail 10. The limiting plates are fixedly connected to both sides of the connecting plate 3. The arc-shaped guide rail 10 constrains the movement trajectory of the arc-shaped slider 8, and the limiting plates prevent the arc-shaped slider 8 from sliding on the arc-shaped guide rail 10 and falling off at the end, ensuring the stability of angle adjustment.

[0019] In this utility model, second slide grooves are symmetrically provided on both sides of the first slide groove. Guide rods 11 are provided in each of the second slide grooves. Protrusions extend from the limiting plate and sleeve the guide rods 11. The guide rods 11 cooperate with the protrusions to eliminate lateral offset during the lifting process and improve the overall structural rigidity. The cross-section of the arc-shaped guide rail 10 is I-shaped. A rack is provided on the inner wall of the arc-shaped guide rail 10. A gear 12 is rotatably provided inside the arc-shaped slider 8. The gear 12 meshes with the rack. A rotating shaft passes through the shaft of the gear 12. A drive motor installed on the outer wall of the arc-shaped slider 8 is coaxially fixed to the rotating shaft. The meshing of the gear 12 and the rack realizes precise displacement control. The drive motor provides power. A first motor 9 is coaxially fixed to the lead screw 2 and installed on the outer wall of the top of the column 1. Multiple anti-slip rubber pads are provided on the grippers of the electric gripper 6. The first motor 9 drives the lead screw 2 to lift and lower at high speed. The anti-slip rubber pads prevent scratches on the lens surface, taking into account both efficiency and safety.

[0020] Working principle: When using this utility model, firstly, the electric gripper 6 is activated to hold the lens. Then, the first motor 9 drives the lead screw 2 to rotate, causing the connecting plate 3 to rise and fall vertically along the first slide groove of the column 1, moving the lens to the preset height of the coating cavity. The telescopic rod of the electric push rod 7 pushes the mounting base 5 to deflect around the hinge point of the ball head column 4, changing the lens pitch angle. The drive motor meshes with the rack of the arc-shaped guide rail 10 through the gear 12, driving the arc-shaped slider 8 to slide along the arc-shaped guide rail 10, causing the mounting base 5 to adjust the yaw angle around the ball head column 4. Then, through the combined control of the telescopic amount of the electric push rod 7 and the rotation angle of the gear 12, the mounting base 5 can achieve multi-degree-of-freedom deflection of pitch and yaw around the ball head column 4, so that the lens surface and the coating evaporation source form the optimal incident angle. At this point, the angle adjustment function of the device is completed.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
