Description

Technical Field

[0001] This utility model relates to the field of quick assembly and disassembly technology of field lens mounts, and in particular to a quick assembly and disassembly structure for fiber optic field lens mounts. Background Technology

[0002] Fiber optic field lens mounts are mechanical structural components used to fix and support field lenses in fiber optic systems. Their main function is to ensure the positional accuracy and stability of the field lens within the optical system. Fiber optic field lenses are core components in laser systems for beam control, primarily used to meet the precision machining and optical application needs of different scenarios by focusing, scanning, or coupling laser beams. In scientific research and measurement fields, field lenses and objective lenses are combined to form confocal systems, focusing laser light onto the sample surface to achieve fluorescence microscopy or two-photon imaging.

[0003] The main structure of a fiber optic field lens consists of a lens, a mount, and a protective structure. Existing quick-release and disassembly structures include snap-fit, magnetic, and threaded quick-release types, with the threaded quick-release type being the most common. The mount and base use a short-pitch coarse thread, and quick tightening and loosening are achieved through rotation, offering stability and efficiency. However, the threaded quick-release type requires manual control of the tightening force; excessive tightening can cause stress deformation of the lens, while excessive loosening can lead to unstable positioning. Current technology uses a design that combines a conical surface with a positioning pin, using elastic washers to compensate for minor deviations, achieving quick and accurate positioning and reducing installation errors. However, this increases the difficulty and cost of manufacturing high-precision positioning components, and troubleshooting complex structures requires specialized tools, extending the maintenance cycle. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-assembly and disassembly structure for fiber optic field lens mounts, aiming to improve the problems of increased processing difficulty and cost of high-precision positioning components in the prior art, the need for special tools for troubleshooting complex structures, and the extended maintenance cycle.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-assembly and disassembly structure for a fiber optic field lens mount, comprising a cylinder, with guide locking mechanisms installed around the bottom of the cylinder. These guide locking mechanisms are primarily used for precise installation of the field lens. A fixing ring is provided at the bottom of the cylinder, and a fixing mechanism is installed at the bottom of the cylinder. This fixing mechanism is primarily used to strengthen the fixation of the field lens. The guide locking mechanism includes guide rods, with multiple guide rods respectively installed around the bottom of the cylinder. A slot is formed on the left and right sides of the middle portion of each guide rod. A spring is fixedly connected to the left and right ends of each guide rod. A wedge is fixedly connected to the left and right ends of each spring. A washer is fixedly connected to the bottom of each wedge. A sliding groove is formed on the bottom of the inner wall of the cylinder.

[0006] As a further description of the above technical solution:

[0007] The fixing mechanism includes a threaded cylinder, which is located at the bottom of the cylinder. A sealing gasket is installed on the outer bottom of the threaded cylinder, and a fixing ring is installed on the outer side of the sealing gasket. Bolts are threadedly connected to the four corners of the middle part of the fixing ring, and nuts are threadedly connected to the top of the bolts.

[0008] As a further description of the above technical solution:

[0009] A second fixing ring is fixedly connected to the bottom of the outer wall of the cylinder, and the second fixing ring is located on the top outer side of the first fixing ring.

[0010] As a further description of the above technical solution:

[0011] A protective mirror is installed inside the third fixed ring, and the third fixed ring is rotatably connected to the first fixed ring.

[0012] As a further description of the above technical solution:

[0013] A lens is installed inside the fixing ring, and an outer cylinder is fixedly connected to the top of the threaded cylinder.

[0014] As a further description of the above technical solution:

[0015] The four corners of the middle part of the second fixed ring are provided with threaded holes, and the guide rod is slidably connected to the slide groove.

[0016] As a further description of the above technical solution:

[0017] The outer cylinder has a second lens installed inside, and the cylinder is threadedly connected to the threaded cylinder.

[0018] As a further description of the above technical solution:

[0019] The inner wall of the cylinder is provided with an annular groove, which is slidably connected to the guide rod, and the guide rod is slidably connected to the slide groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when installing the field lens, after aligning the guide rod with the slide groove, push it upwards. The compression spring causes the inclined block and shim to retract into the slot. When it cannot be pushed, the spring rebounds and drives the inclined block and shim to be inserted between the guide rod and the slide groove, so that the guide rod is fixed in the annular groove to achieve locking. Lens 1 and Lens 2 enable laser focusing through optical design and installation position. After disassembly, a fixing ring 3 and a protective lens are installed below Lens 1 to form a protective structure.

[0022] 2. In this utility model, after the guide rod is locked, the threaded cylinder that matches the internal thread of the cylinder is rotated and screwed in until tight. Before installation, the sealing gasket is put on the outside of the threaded cylinder. After screwing in, the sealing gasket is squeezed to enhance the sealing performance. Finally, the fixing rings one and two are connected through the threaded hole, bolt and nut to enhance the structural stability. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 3 and Figure 4This utility model provides an embodiment of a quick-assembly and disassembly structure for a fiber optic field lens mount, comprising a cylinder 1. Guide locking mechanisms 2 are installed around the bottom of the cylinder 1 on all four sides. The guide locking mechanisms 2 are mainly used for precise installation of the field lens. A fixing ring 5 is provided at the bottom of the cylinder 1, and a fixing mechanism 3 is installed at the bottom of the cylinder 1. The fixing mechanism 3 is mainly used to strengthen the fixation of the field lens. The guide locking mechanism 2 includes guide rods 201, with multiple guide rods 201 respectively installed around the bottom of the cylinder 1. The guide rods 201 have openings on their left and right sides at the center. The cylinder 1 has a slot 202. Springs 205 are fixedly connected to the left and right sides of the middle part of the guide rod 201. Inclined blocks 203 are fixedly connected to the left and right ends of the springs 205. A washer 204 is fixedly connected to the bottom of the inclined blocks 203. A sliding groove 206 is opened at the bottom of the inner wall of the cylinder 1. A protective mirror 8 is installed inside the fixing ring 3 5. The fixing ring 3 5 is rotatably connected to the fixing ring 1 303. An annular groove 10 is opened on the inner wall of the cylinder 1. The annular groove 10 is slidably connected to the guide rod 201. The guide rod 201 is slidably connected to the sliding groove 206.

[0032] Specifically, during the field lens installation, the guide rod 201 is first precisely aligned with the slide groove 206. The guide rod 201 is then pushed upwards vertically. During this pushing process, the guide rod 201 and slide groove 206 apply pressure to the spring 205, causing the spring 205 to retract into the slot 202. The linked wedge block 203 and washer 204 also retract synchronously into the slot 202 along with the spring 205. When the guide rod 201 reaches its limit and can no longer move, it indicates that the preset position has been reached. At this point, the spring 205 is released from its constraint and springs back out due to its own elasticity, causing the wedge block 203 and washer 204 to spring out as well. After springing out, the wedge block 203 is lodged in the gap between the guide rod 201 and the slide groove 206, allowing the guide rod to... Guide rod 201 is securely positioned within the annular groove 10, and can slide within the annular groove 10, thus forming a locking structure to ensure that the field lens will not fall off during operation. Field lens 29 and lens 17, through specific optical curvature design and position layout, can refract and focus the incident laser beam, so that the laser energy is focused at the focal point, meeting the focusing requirements of laser processing technology. When the field lens needs to be disassembled for maintenance, after disassembly, fixing ring 35 and protective mirror 8 can be installed below lens 17. The fixing ring 35 fixes the protective mirror 8 directly below lens 17, which has a protective function and effectively avoids lens 17 from being subjected to external impact and contamination, thereby extending the actual service life of lens 17.

[0033] Reference Figure 2 and Figure 5The fixing mechanism 3 includes a threaded cylinder 301, which is located at the bottom of the cylinder 1. A sealing gasket 302 is installed on the bottom outer side of the threaded cylinder 301. A fixing ring 303 is installed on the outer side of the sealing gasket 302. Bolts 305 are threadedly connected to the four corners of the middle part of the fixing ring 303. Nuts 304 are threadedly connected to the top of the bolts 305. A lens 7 is installed inside the fixing ring 303. An outer cylinder 6 is fixedly connected to the top of the threaded cylinder 301. Threaded holes 11 are opened at the four corners of the middle part of the fixing ring 4. The guide rod 201 is slidably connected to the slide groove 206.

[0034] Specifically, after locking the guide rod 201 and the slide groove 206, the installation structure needs to be further reinforced. During operation, hold the threaded cylinder 301 and rotate it. When the resistance increases significantly and it cannot be rotated further, it indicates that the threaded cylinder 301 has achieved a tight connection with the cylinder 1. Before installing the threaded cylinder 301, the sealing gasket 302 needs to be placed on the outside of the threaded cylinder 301. When the threaded cylinder 301 is screwed into the cylinder 1, the sealing gasket 302 is squeezed between the outer surface of the threaded cylinder 301 and the inner surface of the cylinder 1. Its elastic body deforms and fills the fitting gap, thereby forming a sealing barrier to effectively prevent dust and cutting... To prevent debris and other impurities from entering the internal cavity of the equipment and affecting the normal operation of optical components or mechanical parts, the fixing ring 303 and fixing ring 4 are connected through the threaded hole 11, bolt 305 and nut 304. The bolt 305 passes through the fixing ring 303 and the fixing ring 4 corresponds to the threaded hole 11, and then the nut 304 is tightened at the end of the bolt 305. This connection method makes the fixing ring 303 and fixing ring 4 form a clamping structure, which further enhances the vibration resistance and stability of the entire installation structure and ensures that the field lens always maintains a reliable mechanical positioning state during laser processing.

[0035] Reference Figure 1 A fixing ring 2 4 is fixedly connected to the bottom of the outer wall of the cylinder 1. The fixing ring 2 4 is located on the top of the outer side of the fixing ring 1 303. A lens 2 9 is installed inside the outer cylinder 6. The cylinder 1 is threadedly connected to the threaded cylinder 301.

[0036] Specifically, cylinder 1 has a fixing ring 4, outer cylinder 6 has a lens 9, and cylinder 1 is connected to threaded cylinder 301 for easy subsequent connection.

[0037] Working principle: During the field lens installation operation, the guide rod 201 is first precisely aligned with the slide groove 206 to ensure accurate fit. After alignment, the guide rod 201 is pushed upward. During the pushing process, the guide rod 201 and the slide groove 206 apply pressure to the spring 205, causing the spring 205 to be compressed and retracted into the slot 202. The inclined block 203 and the washer 204 connected to the spring 205 also enter the slot 202 along with the retraction of the spring 205. When the guide rod 201 is pushed upward until it can no longer be pushed, it indicates that the guide rod 201 has reached the predetermined position. At this time, the spring 205 is no longer compressed and springs out due to its own elasticity, simultaneously driving the inclined block 203 and the washer 204. When the inclined block 203 pops out together, it will be locked between the guide rod 201 and the slide groove 206, thereby fixing the guide rod 201 in the annular groove 10. The guide rod 201 can slide in the annular groove 10, thus achieving a locking effect and ensuring that the field lens will not fall off during use. The second lens 9 and the first lens 7 are designed and installed in a specific optical position to focus the laser at one point, thereby achieving the focusing effect required for laser processing. After the field lens is disassembled, the fixing ring 3 5 and the protective mirror 8 can be installed under the first lens 7. The protective mirror 8 is fixed under the first lens 7 to form a protective structure, preventing the first lens 7 from being damaged by external factors and extending the service life of the first lens 7.

[0038] After the guide rod 201 passes through the slide groove 206 and is locked, further fixing operations are required. Rotate the threaded cylinder 301 to connect it with the internal thread of the cylinder 1. The external thread of the threaded cylinder 301 matches the internal thread of the cylinder 1. When rotating the threaded cylinder 301, it will gradually screw into the cylinder 1. When it can no longer be rotated, it indicates that the threaded cylinder 301 is tightly connected to the cylinder 1. Before installing the threaded cylinder 301, the sealing gasket 302 needs to be placed on the outside of the threaded cylinder 301. After the threaded cylinder 301 is screwed into the cylinder 1, the sealing gasket 302 will be squeezed between the threaded cylinder 301 and the cylinder 1. Through the elasticity of the sealing gasket 302, the sealing effect between the threaded cylinder 301 and the cylinder 1 is strengthened, preventing dust, impurities, etc. from entering the equipment and affecting the normal operation of the equipment. The fixing ring 1 303 and fixing ring 2 4 are connected through the threaded hole 11, bolt 305 and nut 304 to further enhance the stability of the entire installation structure and ensure that the field lens remains firm during use.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
