DETAILED DESCRIPTION
[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.
[0024] The embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0025] Reference Figure 1 The present application provides an endoscope fiber trimming device 100 for trimming optical fibers used in endoscopes. The device comprises a base 110, a fiber guide 120, and a cutter 130. The base 110 comprises a length scale region 111, which includes a starting position and an ending position. The fiber guide 120 is movably connected to the base 110 along the length scale region 111 and includes a fiber perforation 121. The cutter 130 is connected to the base 110 and is located at the starting position of the length scale region 111.
[0026] In the present application, the endoscope fiber cutting device 100 uses the fiber optic perforation 121 to limit the passage of the fiber optic bundle that matches its diameter and discards the excess fiber optic strands; after the fiber optic bundle passes through the fiber optic perforation 121, its output end and the fiber optic guide 120 are moved along the length scale area 111 of the base 110. After reaching the predetermined length, the fiber optic bundle is cut by the tool 130 located at the starting position of the length scale area 111, thereby obtaining a fiber optic bundle of preset diameter and length. The operation is convenient, the efficiency is high, the optical fiber 200 is not easily damaged, and the safety is good.
[0027] In some embodiments, the base 110 can be made of metal material, such as aluminum, copper, etc., and the length scale area 111 is directly engraved on the base 110; or a metal sheet can be embedded in the base 110, and a length scale is engraved on the metal sheet to form the length scale area 111.
[0028] In addition, the length scale area 111 includes a starting position and an ending position, which are located at opposite ends of the length scale area 111 along the length direction, wherein the starting position can be flush with the tool holder 131 of the tool 130, and the distance between the ending position and the starting position can be set accordingly according to the actual length requirement of the cut optical fiber, or the distance between the ending position and the starting position can be slightly larger than the actual length requirement of the cut optical fiber, so as to reserve some margin to make up for later erroneous operations.
[0029] In some embodiments, reference Figure 1 and Figure 2 The endoscopic fiber trimming device 100 further includes a slide rail 140, a slider 150, and a support base 160. The slide rail 140 is connected to the base 110 along the length scale region 111, and the slider 150 is slidably connected to the slide rail 140. The support base 160 is connected to the slider 150, and the fiber guide 120 is mounted on the support base 160. In some embodiments, the endoscopic fiber trimming device 100 includes a locking mechanism 151, which is connected to the slider 150 and presses against the slide rail 140 to lock the slider 150.
[0030] In the above embodiment, the fiber guide 120 is connected to the support base 160. It moves indirectly to the base 110 through the cooperation of the slider 150 and the slide rail 140. This makes the movement smoother and more stable, and provides support for the optical fiber 200, ensuring a certain clearance between the optical fiber 200 and the base 110 during movement, thus preventing damage from friction. Furthermore, the locking mechanism 151 provides a locking function after the optical fiber 200 reaches the preset length, preventing the slider 150 from shifting during cutting, thereby ensuring the accuracy of the cut optical fiber 200 length.
[0031] In some embodiments, reference Figure 1 The slide rail 140 is a raised strip arranged along the length scale area 111, which can be fixed to the base 110 by rivets or screws; the bottom of the slider 150 includes a slide groove, which matches the raised strip, and the slider 150 is embedded in the raised strip through the slide groove and can slide along the raised strip.
[0032] In some embodiments, reference Figure 3 Fiber hole 121 includes a fiber entrance and a fiber exit, with the diameter of the fiber entrance being larger than the diameter of the fiber exit. In some embodiments, the diameter of fiber hole 121 gradually decreases from the fiber entrance to the fiber exit. In some embodiments, support base 160 includes a screw hole 161, and the outer wall of fiber guide 120 includes threads, and fiber guide 120 is connected to support base 160 via threads; alternatively, fiber guide 120 is connected to support base 160 via a snap-fit connection.
[0033] In the above embodiment, the fiber optic through-hole 121 has a large diameter at the fiber entrance, which facilitates the alignment and insertion of the optical fiber bundle, while the diameter at the fiber exit is small, which serves to limit the number of optical fibers passing through and ensure that the optical fiber bundle is within the predetermined diameter requirement, that is, the diameter of the fiber exit is the predetermined desired diameter of the optical fiber bundle. Furthermore, the diameter of the optical fiber through-hole 121 gradually decreases from the fiber entrance to the fiber exit, guiding the optical fiber 200 for insertion, making the insertion process smoother. Furthermore, the optical fiber guide 120 is threaded or snap-fitted to the support base 160, making it easy to assemble and disassemble, facilitating the replacement of optical fiber guides 120 with optical fiber exits of different diameters, thereby enabling the production of optical fiber bundles of different predetermined diameters, and providing strong versatility.
[0034] In some embodiments, reference Figure 3 The optical fiber guide 120 is connected to a pointed mouth portion 122 at the optical fiber outlet, and a plurality of optical fiber bundling rubber rings 170 are connected to the outer wall of the pointed mouth portion 122 .
[0035] In this embodiment, after the optical fiber bundle passes through the pointed mouth portion 122, the optical fiber bundling rubber ring 170 can be pulled from the outer wall of the pointed mouth portion 122 to the optical fiber bundle. The optical fiber bundling rubber ring 170 shrinks under its own elasticity to fix and bundle the optical fiber bundle. In addition, multiple optical fiber bundling rubber rings 170 can be bundled with the optical fiber bundle in the same way, which is easy to operate and can be firmly bundled.
[0036] In some embodiments, reference Figure 1 and Figure 2 The tool 130 includes a tool holder 131 and a guillotine 132. The tool holder 131 is connected to the base 110 and is located at the starting position of the length scale area. One end of the guillotine 132 is hinged to the tool holder 131. In some embodiments, the tool holder 131 includes a fiber positioning groove 1311, which corresponds to the fiber perforation 121. In some embodiments, the base 110 is connected to a plurality of foot pads 180, which are connected to the bottom surface of the base 110.
[0037] In the above embodiment, the knife holder 131 is connected to the base 110 and is located at the starting position of the length scale area 111. One end of the guillotine 132 is hinged to the knife holder 131 to cut the optical fiber bundle. A handle can be connected to the guillotine 132 to control the rotation of the guillotine 132, which is easy to operate. In addition, the knife holder 131 includes an optical fiber positioning groove 1311, and the optical fiber bundle is located in the optical fiber positioning groove 1311 for preliminary limiting to prevent the optical fiber bundle from being loose. The optical fiber positioning groove 1311 corresponds to the optical fiber perforation 121 along the length scale area 111, which facilitates the optical fiber bundle to pass through the optical fiber positioning groove 1311 and then through the optical fiber perforation 121. Moreover, the optical fiber positioning groove 1311 and the optical fiber perforation 121 support the optical fiber 200 at two positions, so that there is a certain gap between the optical fiber 200 and the base 110 when it moves, to avoid friction and damage, and the setting is reasonable. In addition, the foot pads 180 at the bottom of the base 110 can be connected to the four corners to play a supporting role, and the foot pads 180 are screwed to the bottom surface of the base 110 to facilitate the height adjustment of the device and provide operating space for the up and down rotation of the shearing blade 132; the foot pads 180 can be made of flexible material, thereby providing a shock-absorbing effect for the cutting process.
[0038] In some embodiments, reference Figure 1 and Figure 2 The guillotine 132 includes a hinged end and a handle end at opposite ends. The hinged end is hinged to the tool holder 131, and the handle end is connected to a handle. The handle is convenient for the operator to hold, and an anti-slip rubber sleeve can be set on it.
[0039] In addition, in some embodiments, the handle end can also be directly connected to other automatic devices to control the up and down rotation of the shear, thereby achieving the cutting of the optical fiber, saving labor costs, and accurate cutting accuracy; in this embodiment, the feeding action of the optical fiber can also be controlled by the corresponding automatic device, so that the feeding and cutting actions are coordinated, further saving labor costs and improving cutting accuracy.
[0040] In particular, the endoscopic optical fiber cutting device 100 of the present application may also include other components. Only components related to this solution are listed here, but this does not limit the structure of the endoscopic optical fiber cutting device 100.
[0041] Although the embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the appended claims.
