Description

Technical Field

[0001] The present invention belongs to the field of assembly and calibration of precision optical systems, and is mainly applied to the assembly of precision optical lens groups, and particularly to large-aperture optical convex-concave lenses having a plurality of lens groups with coating.

Background Art

[0002] With the continuous progress of science and technology, optical lenses are increasingly widely used. Currently, in the actual assembly and adjustment process, when handling large-aperture optical lenses, manual suction cups or transportation are the main methods. However, such suction methods have significant limitations. First, manual suction has unstable suction force, so it is easy to drop during the assembly process, irreversibly damaging the optical lens. Second, although the aperture and shape of the manual suction cup are fixed, the optical lens group has both concave and convex surfaces, and the difference in curvature radius is also large. In the case of an uneven lens with a small curvature radius, the suction force is insufficient. Moreover, due to the large aperture of the optical lens, the suction position must be located at the center of the lens. However, in actual work, it is generally visually confirmed, and after suction, it is easy to sway left and right, so the center of the suction cup and the center of the lens are not accurately aligned, reducing the applicable range of the manual suction cup.

[0003] On the other hand, for an optical lens mounting tool using magnetic adsorption, the magnitude of the magnetic force cannot be controlled. When the optical lens is very heavy, accidental accidents such as dropping are likely to occur. When the optical lens is very lightweight, the lower magnet may be suddenly adsorbed during the approach of the upper magnet, damaging the optical lens. Conventional optical lens assembly devices can satisfactorily attach small-aperture optical lenses. However, in the case of medium- and large-aperture optical lenses, not only is the suction force insufficient, but when the optical lens is heavy, it is difficult to place the lens in the lens fixing frame before attachment. After the vacuum suction cup repeatedly adsorbs the optical lens, if suction marks remain, the film layer will be damaged.

Step 6: Turn off the gas pump to make the magnetic vacuum suction cup lose its suction force, and lift the magnetic vacuum suction cup. Step 7: Use a flexible rope to place the traction frame containing the optical lens at an appropriate position in the large lens tube.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, the present invention will be described in more detail in conjunction with the drawings.

[0018] In view of the difficulty in attaching optical lenses with different apertures and different radii of curvature in a large-aperture optical system with a long lens tube, this embodiment provides a large-aperture optical lens mounting tool by magnetic composite adsorption, which can safely, reliably, and quickly assemble optical lenses with various different radii of curvature, protect the film layer on the lens surface, and facilitate subsequent assembly and adjustment operations (such as eccentricity adjustment) of multiple lens groups, thereby enabling a large-aperture optical lens to be safely and reliably mounted in the lens tube.

[0019] As shown in FIGS. 1 to 3, the structure of the large-aperture optical lens mounting device by magnetic composite adsorption in this embodiment includes a support frame, a motor (specifically including a first motor 3.2 and a second motor 3.3), a magnetic vacuum adsorption cup 2, a magnetic base 8, and a traction frame 14 for mounting the optical lens 7. Here, As the traction frame 14, a plurality of traction frames having different sizes and models are provided and selected based on the shape and size of the optical lens 7 to be mounted. The traction frame 14 is a small frame dedicated to a single optical lens 7. By providing a traction frame 14 dedicated to the optical lens 7, the large-aperture optical lens mounting device can be repeatedly used. Otherwise, when mounting multiple optical lenses 7, the magnetic base 8 cannot be taken out. Conventionally, all the optical lenses 7 are mounted in the same lens tube. When adjusting, the screw 15 on the side wall is directly abutted against the side wall of the optical lens 7 and moved. However, if the screw 15 hits too hard, stress will occur, which will affect the quality of the imaged image. In this embodiment, a dedicated traction frame 14 is used. When performing eccentricity adjustment in the latter half of the mounting operation, the screw 15 only contacts the outer wall of the traction frame 14 without contacting the optical lens 7, so that problems such as stress affecting the quality of the imaged image can be avoided.

[0020] Specifically, as the support frame, a gantry 6 is adopted. The gantry 6 can move back and forth, and both the first motor 3.2 and the second motor 3.3 are fixedly mounted on the gantry 6.

[0021] A measuring rod 5 extending along the lateral direction is attached to the first motor 3.2, and it is most preferable that the first motor 3.2 is attached to the midpoint of the measuring rod 5. Preferably, as shown in FIGS. 7 and 8, the structure of the measuring rod 5 includes a left telescopic rod 5.2 and a right telescopic rod 5.1. A gear is connected to the output end of the first motor 3.2. The left telescopic rod 5.2 meshes with the gear on one side, and the right telescopic rod 5.1 meshes with the gear on the opposite side. Thereby, both ends of the measuring rod 5 can be telescopically extended and retracted laterally by the drive of the first motor 3.2. The position of the measuring rod 5 with respect to the wire rope 18 is in a left-right symmetric relationship, that is, the length extending leftward with respect to the connection point of the wire rope 18 of the left telescopic rod 5.2 is equal to the length extending rightward with respect to the connection point of the wire rope 18 of the right telescopic rod. Most preferably, the measuring rod is further provided with an optical lens 7 and graduations for marking the diameters of the traction frame 14. Fixed pulleys are attached to both ends of the left telescopic rod 5.2 and the right telescopic rod 5.1, that is, a left fixed pulley 5.3 and a right fixed pulley 5.4 are attached to both the left telescopic rod 5.2 and the right telescopic rod 5.1. The middle part of the flexible rope 17 is attached to the second motor 3.3. One end of it hangs down from the right end of the right telescopic rod 5.1 via the left fixed pulley 5.3 and the right fixed pulley 5.4 of the right telescopic rod 5.1 in this order, and the other end hangs down from the left end of the left telescopic rod 5.2 via the right fixed pulley 5.4 and the left fixed pulley 5.3 of the left telescopic rod 5.2 in this order. The flexible rope 17 is extended or retracted along the end of the measuring rod 5 by the drive of the second motor 3.3.

[0022] The gas pump 1 is attached to the middle of the measuring rod 5 by a wire rope 18. A third motor 3.1 is connected to the wire rope 18, and the third motor 3.1 is fixed to the gantry 6. The magnetic vacuum suction cup 2 is connected to the gas pump 1 by a gas guide pipe 19, and its diameter is smaller than the aperture of the optical lens 7. Most preferably, the magnetic vacuum suction cup 2 is further connected to the gas pump 1 by a wire rope. As the gas guide pipe, a telescopic reinforced plastic bellows may be employed. The magnetic vacuum suction cup 2 can move up and down by the drive of the third motor 3.1. An annular flexible gasket 4 is provided at the mouth of the magnetic vacuum suction cup 2 to avoid scratches or dirt on the surface of the optical lens 7. In this embodiment, preferably, the magnetic vacuum suction cup 2 is made of a flexible cast iron material. The inside of the magnetic vacuum suction cup 2 is a conical hollow passage. When the gas pump 1 is working, the inside is in a vacuum state. The larger-diameter end of the passage is the suction end, and the flexible gasket 4 is provided at the suction end. When sucking the optical lens 7, the gas extraction amount of the gas pump 1 may be adjusted according to the weight of the optical lens 7 to be sucked.

[0023] As shown in FIG. 2, the magnetic base 8 includes a magnetic conductor housing made of a magnetic conductive material. A cavity is provided within the magnetic conductor housing, and a rotatable elongated magnet 13 is provided within the cavity of the magnetic conductor housing. The magnetic conductor housing is provided with an elongated magnet rotation control component for controlling the rotation of the elongated magnet 13, which is specifically the handle 11 in this embodiment. Magnetic isolation components are provided on the inner walls of the upper and lower sides of the cavity. The magnetic isolation components are used to cut off the magnetic connection between the magnetic conductor and the elongated magnet, and specifically, the magnetic isolation component is a rectangular copper plate 12 in this embodiment. A tray 9 is attached to the magnetic base 8. Most preferably, the tray is made of a flexible material. The tray 9 is detachably provided. The tray 9 includes various models with both convex and concave surfaces and is selected based on the shape and size of the optical lens to be attached. FIGS. 4 and 5 show the flexible tray structures employed for typical convex and concave optical lenses. An annular buffer component 10 is provided on the surface of the tray 9. In this embodiment, the annular buffer component 10 is an elastic annular thin pad. When in use, the magnetic base 8 is placed below the magnetic vacuum suction cup 2. When the elongated magnet 13 is placed horizontally by controlling the handle 11, that is, when the N pole and S pole of the magnet face the magnetic conductor, the magnetic base 8 has strong magnetism and can be used to adsorb the cast iron suction cup.

[0024] As shown in FIG. 6, the optical lens mounting method using the above-described large-diameter optical lens mounting apparatus by magnetic composite adsorption includes the following steps. Step 1: Based on the convex and concave shapes of the optical lens 7, select an appropriate tray 9 and attach it to the magnetic base 8. Place the optical lens 7 on the tray 9 so that the centers overlap. Use a cleaning tool to clean the optical lens 7 to be attached. The tray 9 and the optical lens 7 are separated by the annular buffer component 10. The magnetic base 8 is placed under the tray 9, and the handle 11 is used to rotate the elongated magnet 13 until it is in a vertical state. At this time, the magnetic base 8 has no magnetism. Refer to FIG. 6(a).

[0025] Step 2: Control the movement of the gantry 6, adjust the telescoping of the measuring rod 5 by the first motor 3.2 so that the flexible ropes 17 at both ends thereof are in close contact with both sides of the optical lens 7. At this time, the length of the measuring rod 5 is approximately equal to the diameter of the optical lens 7, and the magnetic vacuum suction cup 2 is approximately located at the center of the optical lens 7. Control the magnetic vacuum suction cup 2 by the third motor 3.1 to slowly lower it to the central surface of the optical lens 7, and rotate the long magnet 13 by the handle 11 until it is in a horizontal state. At this time, the magnetic base 8 has strong magnetism and can stably adsorb the magnetic vacuum suction cup 2. The optical lens 7 is stably gripped by the magnetic vacuum suction cup 2 and the magnetic base 8. Since the annular buffer component 10 is provided on the tray 9, the optical lens 7 with a coating is not damaged during the gripping process. Refer to FIGS. 6(b), (c), and (d).

[0026] Step 3: Turn on the gas pump 1 to create a negative pressure environment inside the magnetic vacuum suction cup 2, and adjust the gas extraction amount of the gas pump 1 so that the optical lens 7 is stably adsorbed by the magnetic vacuum suction cup 2. Since the flexible gasket 4 is provided on the end face of the magnetic vacuum suction cup 2, the film group on the lens surface can be effectively protected while receiving strong adsorption. Step 4: Control the third motor 3.1, adjust the height of the magnetic vacuum suction cup 2 by the wire rope 18 to lift the optical lens 7 to a preset height, select a traction frame 14 of a corresponding size based on the measurement result of Step 2, place the traction frame 14 at a position corresponding to the flexible ropes 17 at both ends of the measuring rod 5, and fix the flexible ropes 17 to the upper end face of the traction frame 14. At this time, the adsorbed optical lens 7 is approximately located at the center of the traction frame 14. Control the third motor 3.1, adjust the height of the magnetic vacuum suction cup 2 by the wire rope 18, and place the optical lens 7 at an appropriate position on the base of the traction frame 14. Refer to FIGS. 6(e) and (f).

[0027] Step 5: Rotate the long magnet 13 with the handle 11 until it is in a vertical state. At this time, the magnetic base 8 loses its magnetism and the magnetic force disappears, and the magnetic base 8, the tray 9, and the annular buffer component 10 are removed from the opening at the lower part of the traction frame 14. Refer to (g) of FIG. 6.

[0028] Step 6: Turn off the gas pump 1 to eliminate the suction force of the magnetic vacuum suction cup 2, and lift the magnetic vacuum suction cup 2. Refer to (h) of FIG. 6.

[0029] Step 7: Since the flexible ropes 17 at both ends of the measuring rod 5 are respectively fixed to the upper end surface of the traction frame 14, at this time, the flexible ropes 17 function to pull. Control the flexible ropes 17 by the second motor 3.3, and slowly place the traction frame 14 containing the optical lens 7 at an appropriate position in the large lens tube 16. Rotate the screws 15 on both sides of the large lens tube 16 to adjust and fix the traction frame 14 at the middle position of the large lens tube 16. Refer to (i) and (j) of FIG. 6.

[0030] Step 8: For other optical lenses, select appropriate trays 9 and traction frames 14 based on their concave and convex shapes. Place each optical lens 7 into the traction frame 14 according to the above steps, and then sequentially place them into the large lens tube 16 after placing.

[0031] As can be seen from the above, the large-aperture optical lens mounting device and method by magnetic composite adsorption in this embodiment can stably and safely adsorb a large-aperture optical lens having a plurality of lens groups, and can overcome problems such as accidental dropping of the optical lens because the adsorption force is unstable with a single adsorption force. Problems such as scratches and dirt that may occur while the suction cup is in contact with the mirror surface can be avoided. The dedicated traction frame for a single lens reduces the difficulty of subsequent assembly and adjustment of the optical lens having a plurality of lens groups, and can realize stable mounting for both concave and convex optical lenses, effectively solving the problem that it is difficult to assemble because the optical lens is very heavy and the lens tube is deep.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any corrections, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
