Technical Field
[0001] This utility model belongs to the field of optical lens processing technology, specifically, it relates to a telescope lens bonding and pressurizing device. Background Technology

The lens bonding assembly for a telescope provided by this invention has the advantages of being convenient to use, replacing manual pressing of the lens, and accelerating the drying speed of the transparent adhesive.
[0004] Research revealed that existing technologies use threaded rods and curved blocks to apply pressure to cemented lenses. However, the fixed curvature of the curved plate cannot adapt to the curvature of lenses of different specifications, resulting in insufficient edge pressure and deviations in the thickness of the adhesive layer. Furthermore, the limiting rods are set around the perimeter but cannot adaptively position lenses of different specifications, leading to deviations in the center of the lens bonding and thus affecting the telescope's imaging effect.
[0005] In view of this, this utility model is hereby proposed. Utility Model Content
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

The pressure frame is composed of two arc frames forming a cross-shaped frame, and the sliding shaft is slidably fitted inside the pressure frame.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0028] A telescope lens bonding and pressurizing device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including
[0029] The movable block 11 is slidably mounted on the transverse screw. The top surface of the movable block 11 is fixedly provided with a mounting box 10, and a control panel 12 is fixedly provided on one side of the mounting box 10.
[0030] The pressurizing assembly includes a hemispherical block 15, a bidirectional lead screw 16, a pressure plate 17, an arc frame 19, and a pressure frame 28. The hemispherical block 15 is movably disposed within the mounting box 10, and the bidirectional lead screw 16 is rotatably disposed on the mounting box 10. There are two pressure plates 17, which are threaded onto the upper and lower ends of the bidirectional lead screw 16, respectively. There are four arc frames 19, which are slidably disposed at the four corners of the pressure frame 28, and the pressure frame 28 is fixedly disposed at the bottom of the upper pressure plate 17.
[0031] Specifically, a transverse screw is rotatably installed between two support blocks. The transverse screw is driven and controlled by a first motor. An isolation cover is provided outside the transverse screw, and a first frame block and a second frame block are provided inside the isolation cover. A moving block 11 and a baking mechanism are respectively set on the first frame block and the second frame block. By setting a pressure component, a bidirectional lead screw 16 is used to drive the hemispherical block 15 and the pressure frame 28 to move relative to each other. The part of the hemispherical block 15 exposed on the top surface of the mounting box 10 is used to support lenses with different curvatures. The pressure frame 28, in conjunction with the arc frame 19, can fit and press down the curvature of the top surface of the lens to avoid errors caused by insufficient edge pressure. The hemispherical block 15 and the pressure frame 28 simultaneously clamp the glued lens, making the lens glued more tightly. After the glued and pressurized lens is completed, the first motor drives the transverse screw to rotate. The transverse screw drives the moving block 11 and the mounting box 10 to move, so that the glued and pressurized lens in the mounting box 10 enters the baking range of the baking mechanism for drying.
[0032] It is worth noting that the transverse screw, first motor, isolation cover, first frame block, second frame block, illumination lamp, moving block 11, and baking mechanism appearing in this device are all disclosed in detail in the prior art of a telescope lens bonding assembly (CN217803409U), and will not be repeated here.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a double-headed hinge seat 20 is hinged to the bottom of each of the four arc-shaped frames 19. Four moving slots 24 are arrayed on the top surface of the mounting box 10. A sliding shaft 25 is fixedly installed in the moving slot 24. The double-headed hinge seat 20 is slidably installed in the moving slot 24. The sliding shaft 25 passes through the double-headed hinge seat 20.
[0034] like Figure 3 and Figure 4 As shown, a cylinder 23 is fixedly installed inside the mounting box 10. The control panel 12 is electrically connected to the cylinder 23. The output end of the cylinder 23 is connected to a push plate 22. Four single-head hinge seats 26 are arranged in an array on the top surface of the push plate 22. The single-head hinge seats 26 are arranged in a corresponding moving groove 24. A connecting rod 21 connects the single-head hinge seats 26 and the double-head hinge seats 20.
[0035] Specifically, during use, the control panel 12 controls the start and output process of the cylinder 23. The cylinder 23 pushes the push plate 22 to rise and fall within the mounting box 10. The push plate 22 drives the connecting rod 21 to tilt through four single-head hinge seats 26. The tilting movement of the connecting rod 21 pulls the double-head hinge seat 20 to move within the moving slot 24. The double-head hinge seat 20 has a through hole in its center. The double-head hinge seat 20 slides through the sliding shaft 25 through the through hole. The movement of the double-head hinge seat 20 drives the arc frame 19 to move. At this time, the four arc frames 19 achieve relative movement under the drive of the corresponding double-head hinge seats 20, adapting to the edge of the lens for positioning, so that the cemented lens can ensure precise center bonding and avoid the imaging effect caused by position deviation.
[0036] like Figure 4 and Figure 5 As shown, the arc frame 19 is composed of two arc plates forming a U-shaped structure. A sliding shaft 27 is fixedly installed at one end of the arc frame 19 away from the double-headed hinge seat 20. The pressure frame 28 is composed of two arc frames forming a cross-shaped frame. The sliding shaft 27 is slidably fitted inside the pressure frame 28.
[0037] like Figure 3 and Figure 5 As shown, a support frame 13 is fixedly installed at one corner of the top surface of the mounting box 10, and a motor 14 is fixedly installed on the top surface of the support frame 13. The output end of the motor 14 is connected to the top of the bidirectional lead screw 16. The bidirectional lead screw 16 is rotatably positioned between the mounting box 10 and the support frame 13. The control panel 12 is electrically connected to the motor 14. Figure 5 As shown, a pressure shaft 18 is fixedly installed on the bottom surface of the other end of the pressure plate 17. The upper pressure plate 17 is fixedly connected to the top curved surface of the pressure frame 28 through the corresponding pressure shaft 18, and the lower pressure plate 17 is fixedly connected to the bottom surface of the hemispherical block 15 through the corresponding pressure shaft 18.
[0038] Specifically, the top surface of the mounting box 10 has a circular hole corresponding to the size of the hemispherical block 15. The portion of the hemispherical block 15 exposed on the top surface of the mounting box 10 is used to support the curved surface of the lens, while the bottom curved surface of the pressure frame 28 is used to conform to the top curved surface of most curved wafers on the market. When the bidirectional lead screw 16 drives the pressure plates 17 at both ends to move relative to each other, the pressure frame 28 and the hemispherical block 15 move closer or further apart. Under the premise that the four double-headed hinge seats 20 are centered and positioned, the pressure frame 28 presses down... During the process, the arc frame 19 pushes the sliding shaft 27 to slide inside the pressure frame 28 with the top of the double-headed hinge seat 20 as the fixed point. At this time, the inner arc surface of the arc frame 19 and the bottom curved surface of the pressure frame 28 form an arc surface with different curvature to fit the top curved surface of the lens. Under the drive of the bidirectional lead screw 16, the pressure plates 17 on both sides drive the corresponding hemispherical blocks 15 and the pressure frame 28 to clamp the two lenses together to avoid errors caused by insufficient edge pressure, so that the lenses are glued more tightly.
[0039] like Figure 5 As shown, one end of the pressure plate 17 is slidably disposed within the support frame 13, and the end of the pressure plate 17 near the bidirectional lead screw 16 is threadedly engaged with the bidirectional lead screw 16.
[0040] Specifically, when bonding a lens and a plane mirror, both lenses need to be cleaned beforehand. The bottom lens is then placed on top of the hemispherical block 15, i.e., the top surface of the mounting box 10. Transparent adhesive is then evenly applied to the top of this lens. The other lens is then slowly placed on top. At this point, the control panel 12 drives the cylinder 23, which pulls the push plate 22. The push plate 22, through four single-headed hinges 26, four connecting rods 21, and four double-headed hinges 20, drives the four arc-shaped frames 19 to move relative to each other on the mounting box 10. This allows the inner curved surfaces of the four arc-shaped frames 19 to align and center the two lenses. After determining the position between the two lenses, the motor 14 is started. The output shaft of the motor 14 drives the connected bidirectional lead screw 16 to rotate. The rotation of the bidirectional lead screw 16 causes the two sides of the... The relative movement of the pressure plate 17 and the pressure shaft 18 pushes the corresponding hemispherical block 15 and the pressure frame 28 to move closer together. As the pressure frame 28 moves closer to the hemispherical block 15, the four arc-shaped frames 19 swing with the top of the corresponding double-headed hinge 20 as the fixed point. At this time, the inner arc surface of the arc-shaped frame 19 and the bottom curved surface of the pressure frame 28 form an arc surface with different curvatures to fit the top curved surface of the lens, so that the two lenses are pressed against each other. Then the first motor is started, and the first motor drives the transverse screw to rotate. The transverse screw drives the moving block 11 to move. The moving block 11 moves the lens on the mounting box 10 gradually into the isolation cover until the lens at the top of the moving block 11 is directly below the illumination lamp. The temperature generated by the illumination lamp will bake the lens, thereby accelerating the curing of the transparent glue and shortening the time required for lens bonding.
