Description

Technical Field

[0001] This utility model relates to the field of optical fiber processing equipment technology, and in particular to a fiber feeding device. Background Technology

[0002] Optical fibers are widely used in communication equipment. When connecting optical fibers between optoelectronic components, they often need to be cut into smaller segments before splicing. Therefore, before splicing, optical fibers need to be cut to the required length using a dedicated fiber optic cleaver. Currently, the optical fibers are mainly fed into the cleaver manually. However, manual feeding cannot guarantee the smoothness of the feeding process and can easily lead to damage to the optical fibers. Utility Model Content

[0011] The tool mounting base is fixed to the outer ends of the first base plate and the fourth vertical plate. The tool mounting base has feeding ports distributed in the inward and outward directions, and the outer end of the first base plate is disposed in the feeding port.

[0012] The tool mounting base has longitudinally distributed tool mounting slots. The first upper tool is disposed at the upper end of the tool mounting slot, and the first lower tool is fixed at the lower end of the tool mounting slot. The lower end of the first upper tool is configured as a cutting edge. The first cylinder is fixed at the upper end of the fourth vertical plate, and the output end of the first cylinder is connected to the first upper tool to drive the first upper tool to move up and down.

[0023] The fiber feeding device provided by this utility model, through the coordinated action of an upper and lower feeding roller, uniformly conveys the optical fiber forward to the cutting mechanism, which then cuts the optical fiber.

[0034] See Figures 1-3 The fiber feeding device includes: a first support 201, a first vertical plate 202, a second vertical plate 203, a third vertical plate 204, a fourth vertical plate 205, a first substrate 206, an upper feeding roller 207, a lower feeding roller 208, an upper gear 209, a lower gear 210, a first reduction motor 211, and a cutting mechanism. Among them:

[0035] The first support 201 is fixed on the workbench 1.

Optical fiber feeding grooves 220 are distributed on the first substrate 206 perpendicular to the axes of the upper feed roller 207 and the lower feed roller 208, and the optical fiber feeding grooves 220 pass through the through hole. The first geared motor 211 is mounted on the first support 201 and is connected to the shaft of the upper feed roller 207. The cutting mechanism is located on the outside of the first substrate 206.

[0037] In a preferred embodiment provided by this utility model, see [link to previous section]. Figure 1 The fiber feeding device also includes a bracket 212 and a roller 213. The bracket 212 is fixed to the inner ends of the first vertical plate 202 and the second vertical plate 203. The roller 213 is rotatably mounted on the first vertical plate 202 and the second vertical plate 203. The roller 213 is used to support the fed optical fiber.

[0038] In a preferred embodiment of this utility model, see [link to preferred embodiment]. Figure 2 The surfaces of the upper feed roller 207 and the lower feed roller 208 are covered with a flexible material layer. Covering the surfaces of the upper feed roller 207 and the lower feed roller 208 with a flexible material layer can better protect the optical fiber from being crushed or damaged.

[0039] See Figure 1 and Figure 2 The cutting mechanism includes: a tool mounting base 214, a first cylinder 215, a first upper tool 216, a first lower tool 217, a first guide rail 218, and a trapezoidal block 219. The tool mounting base 214 is fixed to the outer ends of the first base plate 206 and the fourth vertical plate 205. The tool mounting base 214 has feed ports 222 distributed in the inward and outward directions. The outer end of the first base plate 206 is disposed in the feed port 222.

[0040] The tool mounting base 214 has longitudinally distributed tool mounting slots 221. A first upper tool 216 is positioned at the upper end of the tool mounting slot 221, and a first lower tool 217 is fixed at the lower end of the tool mounting slot 221. The lower end of the first upper tool 216 is configured as a cutting edge. A first cylinder 215 is fixed to the upper end of the fourth vertical plate 205. The output end of the first cylinder 215 is connected to the first upper tool 216, driving the first upper tool 216 to move up and down. Specifically, a trapezoidal mounting slot is formed at the upper end of the first upper tool 216. A trapezoidal block 219 is embedded in the trapezoidal mounting slot, and the trapezoidal block 219 is fixedly connected to the movable end of the first cylinder 215 by bolts.

A first guide rail 218 is longitudinally fixed within the tool mounting slot 221. The first upper tool 216 is mounted on the first guide rail 218.

[0041] See Figures 1-3 The fiber feeding device operates as follows: One end of the optical fiber is inserted into the inner end of the optical fiber feeding groove 220. The first reduction motor 211 is turned on, and the first reduction motor 211 drives the upper feeding roller 207 to rotate via a rotating shaft. During the rotation of the upper feeding roller 207, the rotating shaft drives the corresponding rotating shaft of the lower feeding roller 208 to rotate synchronously via the first gear and the second gear, thereby driving the lower feeding roller 208 to rotate synchronously. During the rotation of the upper feeding roller 207 and the lower feeding roller 208, the optical fiber is pushed outward. The optical fiber continues to be pushed outward by the cutting mechanism until the end of the optical fiber is inserted into the clamp 3 and clamped and fixed. Then, the three-axis motion mechanism 4 moves in the y-axis direction until the optical fiber is stretched to the required length, and then the optical fiber is cut by the cutting mechanism.

[0042] The fiber feeding device provided in this embodiment of the utility model has at least the following beneficial effects or advantages:

[0043] The fiber feeding device provided in this embodiment of the invention, through the coordinated action of an upper feeding roller and a lower feeding roller, uniformly conveys the optical fiber forward to the cutting mechanism, which then cuts the optical fiber. The same device can simultaneously perform fiber feeding and cutting functions. Since the upper and lower feeding rollers are driven by motors, the motor speed can be controlled by a controller, ensuring uniform rotation of the rollers. This solves the technical problem in existing technologies where the stability of the optical fiber cannot be guaranteed when feeding it into a fixed-length cutting device, easily leading to fiber damage. Furthermore, because this fiber feeding device replaces manual fiber feeding, it further reduces labor costs.
