Description
A fiber optic head adjustment device and fiber optic head adjustment system Technical Field
[0001] This application relates to the field of optical element technology, and more specifically, to a fiber optic head adjustment device and a fiber optic head adjustment system. Background Technology
[0002] Fiber optic technology is a technique that uses optical signals to transmit information over long, thin fibers, and is widely used in communications, data transmission, and other fields. Because the aperture size of an optical fiber typically ranges from tens to hundreds of micrometers, if the position or orientation of the fiber optic connector is off, the aperture of the fiber optic connector and the focal point of the main optical path's focusing system may not align, causing an interruption in optical signal transmission. Therefore, in practical applications, precise adjustment of the fiber optic connector is usually required to ensure a good fit between the connector and the main optical path, guaranteeing smooth optical signal transmission.
[0003] In existing technologies, optical element adjustment frames are typically used to adjust the position of the fiber optic head. These frames usually contain adjusting screws or handwheels; rotating these devices allows for fine-tuning of the fiber optic head's position in a plane, ensuring alignment with other optical elements, such as coaxiality between the fiber optic head and the optical path mechanism. However, this adjustment method generally only allows for adjustment within a single plane, not in directions perpendicular to that plane. In other words, it only enables two-dimensional adjustment of the fiber optic head's position. If the optical signal from the fiber optic head fails to achieve ideal focus in the main optical path, this method is ineffective and often cumbersome. Therefore, finding a convenient, accurate, and reliable way to adjust the position of the fiber optic head is a crucial problem that urgently needs to be solved. Summary of the Invention
[0004] The purpose of this application is to provide an optical fiber head adjustment device and an optical fiber head adjustment system. The optical fiber head adjustment device can conveniently and quickly adjust the position of the optical fiber head in the horizontal and vertical directions, realize three-dimensional adjustment of the position of the optical fiber head, and thus effectively ensure the accuracy of the optical signal transmission path.
[0005] In a first aspect, this application provides an optical fiber head adjustment device for fixing an optical fiber head onto an optical path mechanism and adjusting the position of the optical fiber head in three dimensions, including a horizontal adjustment component and a vertical adjustment component. The horizontal adjustment component comprises, from top to bottom, an optical fiber fixing section and a horizontal adjustment section. The horizontal adjustment component has a first through hole that passes through both the optical fiber fixing section and the horizontal adjustment section from top to bottom for placing the optical fiber head. The vertical adjustment component comprises, from top to bottom, a receiving section, a vertical adjustment section, and a positioning section. The outer side of the vertical adjustment section is threaded, and the positioning section is cylindrical. The vertical adjustment component has a second through hole and a third through hole. The second through hole passes through the receiving section from top to bottom, and the third through hole passes through both the vertical adjustment section and the positioning section from top to bottom. The centerlines of the second and third through holes coincide, and the diameter of the second through hole is larger than the diameter of the third through hole, thus forming a stepped structure at the junction of the receiving section and the vertical adjustment section. The horizontal adjustment component rests on this stepped structure. The side wall of the receiving section is provided with multiple horizontal adjustment holes that penetrate inside and outside. Each horizontal adjustment hole is provided with a horizontal adjuster. The end of the horizontal adjuster contacts the side of the horizontal adjustment section and is used to push the horizontal adjustment component from different directions so as to adjust the position of the horizontal adjustment component in the horizontal plane.
[0006] In one feasible embodiment, the horizontal adjustment section of the horizontal adjustment component is a frustum shape with an upper base smaller than the lower base, and the horizontal adjuster contacts the side of the horizontal adjustment section.
[0007] In one feasible solution, an external thread is provided on the outer side of the fiber optic fixing section of the horizontal adjustment component.
[0008] In one feasible solution, a locking section is provided at the lower end of the positioning section of the vertical adjustment component, and a third through hole extends through the locking section from top to bottom, with the cross-section of the locking section gradually decreasing from top to bottom.
[0009] In one feasible embodiment, the sidewall of the receiving section is provided with at least three horizontal adjustment holes at the same height, and each horizontal adjustment hole is evenly distributed circumferentially along the sidewall of the receiving section.
[0010] In one feasible solution, the horizontal adjustment hole is provided with an internal thread, and the horizontal adjuster is a set screw.
[0011] In one feasible embodiment, the outer side of the receiving section is provided with circumferential graduations to indicate the distance the vertical adjustment member has traveled in the up-down direction.
[0012] Secondly, this application also provides a fiber optic head adjustment system, including a fiber optic head adjustment device, a fiber optic head, and an optical path mechanism, wherein the optical path mechanism is provided with a threaded adjustment hole and a positioning hole. In use, the fiber optic head is inserted into the first through hole of the fiber optic head adjustment device, the vertical adjustment section is threadedly connected to the threaded adjustment hole, and the positioning section is shaped to match the positioning hole.
[0013] In one feasible solution, the optical path mechanism has multiple through-hole threaded locking holes on its side, each with a locking screw inside. A locking section is located at the lower end of the positioning section of the vertical adjustment component, with its cross-section gradually decreasing from top to bottom. During use, the locking screws push the locking section from different directions, causing the vertical adjustment component to move upwards, thus enhancing the stability of the threaded connection between the vertical adjustment section and the threaded adjustment holes.
[0014] In one feasible solution, a fixing nut is provided on the outer side of the fiber optic head, and an internal thread is provided on the inner side of the fixing nut. Correspondingly, an external thread is provided on the outer side of the fiber optic fixing section. In use, the fixing nut is threadedly connected to the fiber optic fixing section, thereby fixing the fiber optic head to the leveling adjustment component.
[0015] Compared with the prior art, the beneficial effects of this application include at least the following:
[0016] The fiber optic head adjustment device of this application, by setting horizontal and vertical adjustment components, allows for adjustment of the fiber optic head position in both horizontal and vertical directions, enabling three-dimensional adjustment of the fiber optic head position and effectively ensuring the accuracy of the optical signal transmission path. Simultaneously, since the position of the vertical adjustment section can be adjusted via threads, it facilitates precise adjustment of the fiber optic head's vertical position, achieving accurate focusing of the optical signal. Furthermore, the fiber optic head adjustment device of this application has a simple structure and is easy to use, effectively reducing related production and maintenance costs. It also allows for easy modification of existing optical path mechanisms to apply the fiber optic head adjustment device of this application.
[0017] Furthermore, in the fiber optic head adjustment device, the horizontal adjustment section of the horizontal adjustment component is set to a frustum shape with the upper base smaller than the lower base. Therefore, when adjusting the position of the fiber optic head in the horizontal plane, it can effectively prevent the horizontal adjustment section from deviating, so that the direction of the fiber optic head always forms a good match with the main optical path, ensuring the accuracy of the optical signal transmission path.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0026] As shown in Figures 1-3, this application provides an optical fiber head adjustment device, including a horizontal adjustment component 1 and a vertical adjustment component 2. The horizontal adjustment component 1, from top to bottom, includes an optical fiber fixing section 101 and a horizontal adjustment section 102. The horizontal adjustment component 1 has a first through hole 111 that passes through both the optical fiber fixing section 101 and the horizontal adjustment section 102 from top to bottom, for placing the optical fiber head 3. The vertical adjustment component 2, from top to bottom, includes a receiving section 201, a vertical adjustment section 202, and a positioning section 203. The outer side of the vertical adjustment section 202 is threaded, and the positioning section 203 is cylindrical. The vertical adjustment component 2 has a second through hole 252 and a third through hole 253. The second through hole 252 passes through the receiving section 201 from top to bottom, and the third through hole 253 passes through both the vertical adjustment section 202 and the positioning section 203 from top to bottom. The centerlines of the second through hole 252 and the third through hole 253 coincide, and the diameter of the second through hole 252 is larger than the diameter of the third through hole 253, thus forming a stepped structure 251 at the junction of the receiving section 201 and the vertical adjustment section 202. The horizontal adjustment member 1 is placed on the stepped structure 251. The side wall of the receiving section 201 is provided with a plurality of horizontal adjustment holes 211 penetrating inside and outside. Each horizontal adjustment hole 211 is provided with a horizontal adjuster 212. The end of the horizontal adjuster 212 contacts the side of the horizontal adjustment section 102 and is used to push the horizontal adjustment member 1 from different directions to adjust the position of the horizontal adjustment member 1 in the horizontal plane. Preferably, as shown in FIG1, the side wall of the receiving section 201 is provided with at least three horizontal adjustment holes 211 located at the same height, and each horizontal adjustment hole 211 is evenly distributed along the circumference of the side wall of the receiving section 201.
[0027] In use, the vertical adjustment section 202 can be connected to the external optical path mechanism 4 via the outer thread to fix the vertical adjustment component 2. Then, the horizontal adjustment section 1 is placed on the stepped structure 251, so that the first through hole 111, the second through hole 252, and the third through hole 253 form a complete optical signal path. Afterward, the fiber optic head can be inserted into the first through hole 111, and the accuracy of the optical signal transmission path of the fiber optic head 3 can be observed in real time, i.e., whether the optical signal can be projected to the designated position and accurately focused. Based on the actual deviation of the optical signal, each horizontal adjuster 212 can be adjusted separately to move the horizontal adjustment component 1 towards the target direction. The vertical adjustment component 2 can be moved up and down via the outer thread of the vertical adjustment section 202, ultimately adjusting the fiber optic head accurately into place.
[0028] Preferably, as shown in Figure 1, the horizontal adjustment section 102 of the horizontal adjustment member 1 can be configured as a frustum shape with an upper base smaller than the lower base. In this way, when the horizontal adjustment member 1 pushes against the side of the horizontal adjustment section 102, it generates a downward vertical force on the horizontal adjustment section 102, thereby pressing the horizontal adjustment section 102 tightly against the stepped structure 251. This prevents the horizontal adjustment section 102 from being accidentally displaced due to interference from other factors, thus avoiding affecting the accurate transmission of the optical signal.
[0029] The fiber optic head adjustment device of this application, by setting horizontal and vertical adjustment components, allows for adjustment of the fiber optic head position in both horizontal and vertical directions, enabling three-dimensional adjustment of the fiber optic head position and effectively ensuring the accuracy of the optical signal transmission path. Simultaneously, since the position of the vertical adjustment section can be adjusted via a thread, it facilitates precise adjustment of the fiber optic head's vertical position, thereby achieving accurate focusing of the optical signal. Furthermore, the fiber optic head adjustment device of this application has a simple structure and is easy to use, effectively reducing related production and maintenance costs. It also allows for easy modification of existing optical path mechanisms to apply the fiber optic head adjustment device of this application. Further, the horizontal adjustment section of the horizontal adjustment component in the fiber optic head adjustment device is set as a frustum shape with an upper base smaller than the lower base. Therefore, when adjusting the position of the fiber optic head in the horizontal plane, it effectively prevents the horizontal adjustment section from skewing, ensuring that the direction of the fiber optic head always maintains good alignment with the main optical path and ensuring the accuracy of the optical signal transmission path.
[0030] In one embodiment, an internal thread can be provided within the leveling hole 211, and a set screw can be used as the leveling adjuster 212. In use, the operator can screw each leveling adjuster 212 individually to move it within the corresponding leveling hole 211. Using a set screw as the leveling adjuster 212 helps improve the accuracy of leveling adjustment, and the set screw structure is relatively simple, requiring no additional locking device, thus facilitating use and maintenance. Furthermore, a rotatable ball bearing (not shown in the figure) can be provided at the end of each leveling adjuster 212. When the leveling member 1 moves, the ball bearing can roll against the side of the leveling member 1, making the movement of the leveling adjuster 212 smoother and improving the efficiency of leveling adjustment. Additionally, a gripping part (not shown in the figure) for easy manual operation can be provided at the head of the set screw, and the gripping part is located outside the receiving section 201, allowing the operator to directly screw the leveling adjuster 212.
[0031] In one embodiment, the optical fiber fixing section 101 of the horizontal adjustment member 1 is provided with an external thread (not shown in the figure). In actual production, the optical fiber head is usually equipped with a fixing nut for locking, and the external thread of the optical fiber fixing section 101 can cooperate with the fixing nut to fix the optical fiber head.
[0032] In one embodiment, as shown in FIG3, a locking section 204 may also be provided at the lower end of the positioning section 203 of the vertical adjustment member 2. The third through hole 253 passes through the locking section 204 from top to bottom, and the cross-section of the locking section 204 gradually decreases from top to bottom.
[0033] In one embodiment, the outer side of the receiving section 201 may be provided with a circumferential scale to indicate the distance the vertical adjustment member 2 travels in the up-down direction. The scale can convert the up-down movement distance of the vertical adjustment member 2 into a rotation angle, which is convenient for the operator to observe and control. Preferably, the outer side of the receiving section 201 may also be provided with a textured surface to facilitate the operator to manually rotate the vertical adjustment member 2.
[0034] This application also provides a fiber optic head adjustment system, including a fiber optic head adjustment device, a fiber optic head 3, and an optical path mechanism 4. The optical path mechanism 4 is provided with a threaded adjustment hole 401 and a positioning hole 402.
[0035] In use, the fiber optic head 3 is inserted into the first through hole 111 of the fiber optic head adjustment device. The vertical adjustment section 202 is threadedly connected to the threaded adjustment hole 401, and the positioning section 203 is shaped to fit the positioning hole 402. By turning the vertical adjustment section 202, the vertical adjustment component 2 can move up and down. Preferably, the positioning section 203 and the positioning hole 402 can be machined with high precision (e.g., with IT5 tolerance grade) to ensure a good fit, such as good coaxiality. This ensures that, under the limit of the positioning section 203, its direction remains vertical regardless of how the positioning section 203 rotates or translates, thereby maximizing the accuracy of the optical signal transmission path.
[0036] In one embodiment, as shown in Figure 1, the optical path mechanism 4 has multiple through-holes 403 threaded locking holes 403 on its side, and each threaded locking hole 403 has a locking screw 404 inside. Correspondingly, the lower end of the positioning section 203 of the vertical adjustment member 2 has a locking section 204, the cross-section of which gradually decreases from top to bottom. In use, the operator can turn each locking screw 404 to push the locking section 204 of the vertical adjustment member 2 from different directions. Since the locking section 404 is actually a frustum shape with the upper bottom surface larger than the lower bottom surface, the pushing of the locking screw 404 will apply a vertically upward component force to the locking section 404, thereby causing the vertical adjustment member 2 to move upward, making the external thread of the vertical adjustment section 202 and the internal thread of the threaded adjustment hole 401 more tightly pressed together, thereby enhancing the stability of the threaded connection. In addition, a grip part (not shown in the figure) that is easy to operate manually can be provided at the head of the locking set screw 404, and the grip part is located outside the optical path mechanism 4, so that the operator can directly turn the locking set screw 404.
[0037] In one embodiment, as shown in FIG1, a fixing nut 301 can be provided on the outside of the fiber optic head 3. The fixing nut 301 has an internal thread on its inner side, and the fiber optic fixing section 101 has a corresponding external thread on its outer side. In use, the fixing nut 301 is connected to the external thread of the fiber optic fixing section 101 to fix the fiber optic head 3 to the horizontal adjustment member 1. When needed, the fixing nut 301 can be unscrewed from the fiber optic fixing section 101 to remove the fiber optic head 3 from the first through hole 111. Alternatively, a locking device can be provided on the outer side of the fiber optic head 3 and the outer side of the fiber optic fixing section 101 to achieve a fixed connection between the fiber optic head 3 and the fiber optic fixing section 101.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
