Description

Technical Field

[0001] The invention relates to the technical field of lens installation, and in particular to a mounting assembly for a zoom lens. Background Art

[0002] A zoom lens is a lens that can change the focal length. The focal length is adjusted by moving the lens inside the lens, thereby changing the viewing angle and composition of the captured image. The zoom lens is relatively complex in optical design and usually contains multiple groups of lenses that can be moved and adjusted to achieve focal length changes. The zoom lens includes multiple lens groups. During the installation of the zoom lens, the lens and the mounting ring need to be installed together to form a lens group, and then the lens group can be installed in the outer shell of the zoom lens. The overall operation is relatively complicated.

Before the lens is installed, it is necessary to manually check whether there are cracks at the corners of the lens. The workload is large and there are certain errors in manual inspection. After the lens group is installed, it is necessary to manually inspect the connection effect between the lens and the mounting ring. This is time-consuming and laborious. During this inspection process, the staff is required to press the lens by hand, which reduces the cleanliness of the lens. After the inspection is completed, it is still necessary to manually inspect. Therefore, a zoom lens mounting assembly is provided. Summary of the invention

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 12 A zoom lens mounting assembly includes a workbench 1, a bracket 2 is fixedly connected to the upper side of the workbench 1, and a positioning assembly is installed on the upper side of the workbench 1, such as Figure 2 The positioning assembly includes two clamping blocks 44. Two positioning frames 42 are fixedly connected to the upper side of the workbench 1. A rotating rod 43 is threadedly connected in the two positioning frames 42. The rotating rod 43 and the clamping block 44 are rotatably connected, and the clamping block 44 and the workbench 1 are slidably connected. An auxiliary rod 46 is rotatably connected to the side wall of the bracket 2. The auxiliary rod 46 is connected to the rotating rod 43 through a pulley assembly 45. Anti-skid rubber pads are fixedly connected in the two clamping blocks 44 to improve the friction of the two clamping blocks 44.

[0032] First, the pulley assembly 45 includes two pulleys and a conveyor belt, one of which is fixedly connected to the auxiliary rod 46, and the other is slidably connected to the rotating rod 43. Secondly, during the installation of the zoom lens, the zoom lens housing is placed between the two clamping blocks 44, and then the auxiliary rod 46 is rotated. The auxiliary rod 46 drives the rotating rod 43 to rotate through the pulley assembly 45. Since the rotating rod 43 is threadedly connected to the positioning frame 42, the rotating rod 43 is rotatably connected to the clamping block 44, and the clamping block 44 is slidably connected to the workbench 1, the rotating rotating rod 43 drives the clamping block 44 to move in a direction close to each other until the two clamping blocks 44 are both against the zoom lens housing, thereby completing the limiting and fixing operation of the zoom lens housing;

[0033] like Figure 3, Figure 4 , Figure 5 , Figure 6 A lens adsorption assembly is installed on the upper side of the workbench 1. The lens adsorption assembly includes a plurality of vacuum suction cups 4. A rotating plate 12 is rotatably connected to the outer side of each vacuum suction cup 4. A first connecting rod 17 is fixedly connected to the outer side of the rotating plate 12. A fixed frame 10 is fixedly connected to the outer side of the first connecting rod 17. A second connecting rod 18 is fixedly connected to the outer side of the fixed frame 10. A slider 5 is fixedly connected to the outer side of the second connecting rod 18. A slide rail 3 is fixedly connected to the upper side of the workbench 1. The slider 5 and the slide rail 3 are slidably connected up and down. The side wall of the slider 5 is threadedly connected to a screw. The threaded rod 11 is rotatably connected to the outer side of the threaded rod 11 with a clamping rod 7, the side wall of the slide rail 3 is evenly fixedly connected to the limit rod 6, the fixed frame 10 is rotatably connected to the threaded cylinder 19, the threaded cylinder 19 is slidably connected to the bolt 20, the outer side of the threaded cylinder 19 is fixedly connected to the gear 21, the fixed frame 10 is slidably connected to two racks 22, the two racks 22 are meshed with the gear 21, the side walls of the two racks 22 are fixedly connected to the third connecting rod 25, and the outer side of the third connecting rod 25 is fixedly connected to the square block 16 through the round rod 15;

[0034] First, the vacuum suction cup 4 is a device that uses vacuum technology to generate adsorption force. It is mainly used to absorb and fix various objects, such as metal, glass, ceramics, etc. Its working principle is based on the pressure difference between the inside and outside of the vacuum chamber. This is a relatively mature technology in real life and no unnecessary elaboration is made. Secondly, during the installation of the zoom lens, when it is necessary to assemble the lens therein, first place the lens on the lower side of the vacuum suction cup 4 and turn the bolt 20. Since the bolt 20 and the threaded barrel 19 are connected by sliding up and down, and the bolt 20 and the fixed frame 10 are threadedly connected, the rotating bolt 20 will drive the threaded barrel 19 to rotate, and the threaded barrel 19 drives the gear 21 to rotate. The gear 21 drives the third connecting rod 25 to move toward each other through the meshing rack 22. The third connecting rod 25 drives the square block 16 to move toward each other through the round rod 15 until the two square blocks 16 are against the lens. At this time, the lens is located on the lower side of the vacuum suction cup 4, and the center of the lens and the center of the vacuum suction cup 4 are on the same vertical line. At this time, start the vacuum suction cup 4. The lens is sucked, and the lens is released, and the corresponding assembly operation is started, such as assembling the corresponding mounting ring on the outer side of the lens, etc. In this process, the bolt 20 can be rotated again to disconnect the square block 16 from the lens, so as to facilitate the assembly operation. In the above working process, the positioning operation of the lens can be completed, so that the lens and the zoom lens housing are in a concentric state, which is convenient for subsequent operations. In the above process, the threaded rod 11 can be rotated to move the threaded rod 11 from the slider 5, and at the same time, the threaded rod 11 drives the clamping rod 7 to move, so that the clamping rod 7 and the limit rod 6 are disconnected, and then the slider 5 is moved up and down along the slide rail 3. The slider 5 drives the rotating plate 12 to move up and down through the first connecting rod 17, the fixed frame 10, and the second connecting rod 18. The rotating plate 12 drives the lens to move up and down through the vacuum suction cup 4 until the position of the lens meets the working requirements, and then the threaded rod 11 is screwed into the slider 5 again, and the clamping rod 7 is located between the two limit rods 6, so as to complete the adjustment and fixing operation of the slider 5 and the lens position, and provide convenience for subsequent assembly operations;

[0035] Furthermore, since the bolt 20 and the fixing frame 10 are threadedly connected, that is, there is a self-locking phenomenon between the bolt 20 and the fixing frame 10, in the absence of external force, the bolt 20 will not be displaced relative to the fixing frame 10, that is, the round rod 15 and the square block 16 will not move.

[0036] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11A cleaning assembly is installed on the lower side of the rotating plate 12, and the cleaning assembly includes two elastic cleaning cloths 23. The rotating plate 12 is fixedly connected through two fixed cylinders 14, and the two fixed cylinders 14 are slidably connected with slide rods 28. A first spring 27 is fixedly connected between the slide rod 28 and the fixed cylinder 14. The lower sides of the two slide rods 28 are commonly fixedly connected with a moving ring 13. A control groove 29 is opened on the side wall of the square block 16. A positioning cylinder 30 is fixedly connected to the inner wall of the control groove 29. A positioning rod 32 is slidably connected in the positioning cylinder 30. A second spring 31 is fixedly connected between the rod 32 and the positioning cylinder 30, a positioning plate 24 is slidably connected to the outer side of the positioning rod 32, a blocking rod 33 is slidably connected to the outer side of the positioning rod 32, a baffle 36 is fixedly connected to the outer side of the baffle 33, oblique grooves 40 are opened on both sides of the control groove 29, oblique rods 41 are slidably connected in the two oblique grooves 40, the oblique rods 41 and the baffle 36 are fixedly connected, one end of the two elastic cleaning cloths 23 is fixedly connected to the control groove 29, and the other end of the two elastic cleaning cloths 23 is fixedly connected to the moving ring 13;

[0037] First, when the lens is adsorbed on the lower side of the vacuum suction cup 4, the lens and the square block 16 are against each other. Before this operation, the lens has been against the positioning plate 24, which will cause the positioning plate 24 to move to the left relative to the square block 16 (at this time, the positioning plate 24 is moved to the left). Fig. 9 perspective, and Fig. 9 , Fig.11 The square blocks 16 in the Figure 7 The square block 16 on the left side of the center, Figure 7 The square block 16 on the right and the square block 16 on the left have the same internal movement working principle), the positioning plate 24 drives the positioning rod 32 to move leftward, and the positioning rod 32 compresses the second spring 31 while driving the blocking rod 33 and the blocking plate 36 to move leftward. Under the restriction of the inclined groove 40 and the inclined rod 41, the blocking rod 33 and the blocking plate 36 as a whole will not only move leftward, but also move downward, that is, the blocking rod 33 and the blocking plate 36 as a whole will move in the lower left direction. When the lens and the square block 16 are against each other, the blocking plate 36 loses the restriction on the elastic cleaning cloth 23, which causes the elastic cleaning cloth 23 to be against the lens, that is, refer to the attached Fig.12 , the elastic cleaning cloth 23 changes from the "X" state to the "Y" state. At this time, the elastic cleaning cloth 23 is against the surface of the lens. The vacuum suction cup 4 is rotated, and the vacuum suction cup 4 drives the lens to rotate. Since the elastic cleaning cloth 23 is always against the surface of the lens, a friction cleaning effect will be formed on the surface of the lens to keep the cleanliness of the lens.

[0038] A displacement sensor 35 is fixedly connected in the control groove 29, and the output end of the displacement sensor 35 is always against the elastic cleaning cloth 23. The displacement sensor 35 is a sensor that converts physical displacement into an electrical signal. In this solution, the displacement sensor 35 will generate corresponding electrical signals in both the X and Y states. When the elastic cleaning cloth 23 is used to clean the lens, since the elastic cleaning cloth 23 is always against the lens, and at the same time, the elastic cleaning cloth 23 is always against the corners of the lens, when the lens follows the rotation of the vacuum suction cup 4, if the electrical signal emitted by the displacement sensor 35 does not have any surface, it means that the lens is not damaged. If the electrical signal emitted by the displacement sensor 35 fluctuates, it means that the lens has certain quality problems and needs to be processed in time.

[0039] A detection assembly is installed in the square block 16, and the detection assembly includes a fourth connecting rod 34 fixedly installed on the outer side of the positioning plate 24, a smooth round head 26 is fixedly connected to the outer side of the fourth connecting rod 34, two clamping plates 38 are fixedly connected to the side wall of the positioning plate 24, a third spring 39 is fixedly connected between the two clamping plates 38 and between the positioning rods 32, a fifth connecting rod 37 is fixedly connected between the two clamping plates 38, and the fifth connecting rod 37 slides through the positioning rod 32, a regulating plate 8 is fixedly connected to the upper side of the vacuum suction cup 4, and a plurality of regulating rods 9 are fixedly connected to the outer circumferential side of the regulating plate 8, and the surfaces of the regulating rod 9 and the smooth round head 26 are both smooth;

[0040] First, during the cleaning process of the lens, the rotating vacuum suction cup 4 will drive the regulating plate 8 and the regulating rod 9 to rotate, and when the regulating rod 9 and the smooth round head 26 are in contact with each other, the positioning plate 24 will be driven to move downward. When the regulating rod 9 and the smooth round head 26 are disconnected, the positioning plate 24 moves upward relative to the square block 16 and returns to its original position under the action of the third spring 39, thereby causing the positioning plate 24 to move up and down. However, since the corners of the vacuum suction cup 4 are made of soft material (such as rubber), the overall cleaning effect is not affected. However, after the lens is assembled, the above operation is repeated to make the positioning plate 24 and the mounting ring on the outer side of the lens contact with each other. When the vacuum suction cup 4 is rotated again, at this time, under the action of the first spring 27, the sliding rod 28 The moving ring 13 will apply a downward force to the lens. When the rotating regulating plate 8 and the regulating rod 9 drive the positioning plate 24 to move up and down through the smooth round head 26 and the fourth connecting rod 34, if the connection between the mounting ring and the lens is good, the electrical signal emitted by the displacement sensor 35 should be periodically changed, that is, the shape of the elastic cleaning cloth 23 will also change periodically. If there is looseness between the mounting ring and the lens, when the positioning plate 24 drives the mounting ring to move up and down, the lens will not always follow the mounting ring to move up and down, that is, the position of the moving ring 13 that is against the lens will change, the shape of the elastic cleaning cloth 23 will not change periodically, and the electrical signal emitted by the displacement sensor 35 will fluctuate, thereby completing the detection effect between the mounting ring and the lens.

[0041] In the present invention, during the installation of the zoom lens, the zoom lens housing is placed between the two clamping blocks 44, and then the auxiliary rod 46 is rotated, and the auxiliary rod 46 drives the rotating rod 43 to rotate through the pulley assembly 45. Since the rotating rod 43 is threadedly connected to the positioning frame 42, the rotating rod 43 and the clamping block 44 are rotationally connected, and the clamping block 44 and the workbench 1 are slidably connected, the rotating rotating rod 43 drives the clamping block 44 to move in a direction close to each other until both clamping blocks 44 are against the zoom lens housing, thereby completing the limiting and fixing operation of the zoom lens housing;

[0042] During the installation of the zoom lens, when it is necessary to perform assembly operation on the lens therein, first place the lens on the lower side of the vacuum suction cup 4, and rotate the bolt 20. Since the bolt 20 and the threaded barrel 19 are connected by sliding up and down, and the bolt 20 and the fixed frame 10 are threadedly connected, the rotating bolt 20 will drive the threaded barrel 19 to rotate, and the threaded barrel 19 drives the gear 21 to rotate. The gear 21 drives the third connecting rod 25 to move toward each other through the meshing rack 22. The third connecting rod 25 drives the square block 16 to move toward each other through the round rod 15 until the two square blocks 16 are against the lens. At this time, the lens is located on the lower side of the vacuum suction cup 4, and the center of the lens and the center of the vacuum suction cup 4 are on the same vertical line. At this time, start the vacuum suction cup 4 to suck the lens, release the lens, and start the corresponding assembly operation, such as assembling the corresponding mounting ring on the outside of the lens. In this process, The bolt 20 can be rotated again to disconnect the square block 16 from the lens, which is convenient for the assembly operation. In the above working process, the positioning operation of the lens can be completed, so that the lens and the zoom lens housing are in a concentric state, which is convenient for the subsequent operation. In the above process, the threaded rod 11 can be rotated to move the threaded rod 11 from the slider 5. At the same time, the threaded rod 11 drives the clamping rod 7 to move, so that the clamping rod 7 and the limit rod 6 are disconnected, and then the slider 5 is moved up and down along the slide rail 3. The slider 5 drives the rotating plate 12 to move up and down through the first connecting rod 17, the fixed frame 10, and the second connecting rod 18. The rotating plate 12 drives the lens to move up and down through the vacuum suction cup 4 until the position of the lens meets the working requirements. Then the threaded rod 11 is screwed into the slider 5 again, and the clamping rod 7 is located between the two limit rods 6. The adjustment and fixing operations of the slider 5 and the lens position are completed, which is convenient for the subsequent assembly operation.

[0043] When the lens is adsorbed on the lower side of the vacuum suction cup 4, the lens and the square block 16 are in contact with each other. Before this operation, the lens has been in contact with the positioning plate 24, which will cause the positioning plate 24 to move leftward relative to the square block 16 (at this time, Fig. 9 perspective, and Fig. 9 , Fig.11 The square blocks 16 in the Figure 7 The square block 16 on the left side of the center, Figure 7The square block 16 on the right and the square block 16 on the left have the same internal movement working principle), the positioning plate 24 drives the positioning rod 32 to move leftward, and the positioning rod 32 compresses the second spring 31 while driving the blocking rod 33 and the blocking plate 36 to move leftward. Under the restriction of the inclined groove 40 and the inclined rod 41, the blocking rod 33 and the blocking plate 36 as a whole will not only move leftward, but also move downward, that is, the blocking rod 33 and the blocking plate 36 as a whole will move in the lower left direction. When the lens and the square block 16 are against each other, the blocking plate 36 loses the restriction on the elastic cleaning cloth 23, which causes the elastic cleaning cloth 23 to be against the lens, that is, refer to the attached Fig.12 , the elastic cleaning cloth 23 changes from the "X" state to the "Y" state, at which time the elastic cleaning cloth 23 and the lens surface are in contact, and the vacuum suction cup 4 is rotated, and the vacuum suction cup 4 drives the lens to rotate. Since the elastic cleaning cloth 23 is always in contact with the lens surface, a friction cleaning effect is formed on the lens surface to keep the lens clean;

[0044] In this solution, the displacement sensor 35 will generate corresponding electrical signals in both the X and Y states. When the lens is cleaned by the elastic cleaning cloth 23, since the elastic cleaning cloth 23 is always against the lens and the corners of the lens are always against the elastic cleaning cloth 23, when the lens rotates with the vacuum suction cup 4, if the electrical signal emitted by the displacement sensor 35 does not have any surface, it means that the lens is not damaged. If the electrical signal emitted by the displacement sensor 35 fluctuates, it means that the lens has certain quality problems and needs to be dealt with in a timely manner.

[0045] During the cleaning process of the lens, the rotating vacuum suction cup 4 will drive the regulating plate 8 and the regulating rod 9 to rotate, and the regulating rod 9 and the smooth round head 26 will drive the positioning plate 24 to move downward. When the regulating rod 9 and the smooth round head 26 are disconnected, the positioning plate 24 moves upward relative to the square block 16 and returns to its original position under the action of the third spring 39, thereby causing the positioning plate 24 to move up and down. However, since the corners of the vacuum suction cup 4 are made of soft material (such as rubber), the overall cleaning effect is not affected. However, after the lens is assembled, the above operation is repeated to make the positioning plate 24 and the mounting ring on the outer side of the lens abut against each other. When the vacuum suction cup 4 is rotated again, at this time, under the action of the first spring 27, the sliding rod 28 and the moving plate 24 are moved upward relative to the square block 16 and return to their original position. The moving ring 13 will apply a downward force to the lens. When the rotating regulating plate 8 and regulating rod 9 drive the positioning plate 24 to move up and down through the smooth round head 26 and the third connecting rod 25, if the connection between the mounting ring and the lens is good, the electrical signal emitted by the displacement sensor 35 should be periodically changed, that is, the shape of the elastic cleaning cloth 23 will also change periodically. If there is looseness between the mounting ring and the lens, when the positioning plate 24 drives the mounting ring to move up and down, the lens will not always follow the mounting ring to move up and down, that is, the position of the moving ring 13 that is against the lens will change, the shape of the elastic cleaning cloth 23 will not change periodically, and the electrical signal emitted by the displacement sensor 35 will fluctuate, thereby completing the detection effect between the mounting ring and the lens.
