Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cutting, in particular to a rolling friction optical fiber cutting knife device. Background Art

[0002] Fiber optic cutting is used to cut quartz glass optical fibers as thin as a hair. The cut optical fiber ends are still flat after being magnified hundreds of times, and can be used for device packaging, cold connection, and discharge welding.

[0003] Existing optical fiber cutting generally includes a base, a pressure cover hinged to the base, an elastic pressing component installed on the pressure cover, a clamp component installed on the base, and a cutting component slidably arranged on the base. The cutting steps are: placing the stripped optical fiber on the clamp component for clamping; rotating the pressure cover to fit the base so that the two sets of pressure pads press the optical fiber; pushing the cutting component to slide forward so that the cutting knife forms a scratch on the surface of the optical fiber. After the cutting component forms a scratch on the surface of the optical fiber, the elastic pressing component is triggered, so that the elastic pressing component cooperates with the optical fiber cutting knife to press the optical fiber, thereby realizing the cutting of the optical fiber.

[0004] In addition, in the prior art, the linkage between the cutting assembly and the sliding mechanism in the optical fiber cutting knife device is relatively common, and the sliding of the sliding mechanism can drive the cutting knife to cut. In the optical fiber cutting, the pressure breaker in the elastic pressure breaking assembly generally uses a flat pressure block. During the cutting process, the flat pressure block presses the sliding mechanism in contact with it by sliding friction, thereby driving the cutting knife to complete the cutting. The flat pressure block has a simple structure, but the contact surface friction between the pressure breaker and the sliding mechanism is relatively large during use, which will cause the contact part of the friction cover plate of the pressure breaker and the sliding mechanism to wear, and the uneven surface of the friction cover plate will cause jamming during the squeezing process, and the large friction during the squeezing process will also cause the cutting knife device to jam. Utility Model Content

[0005] The problem to be solved by the utility model is to solve the problem of the cutting knife device being stuck due to excessive friction between the contact surface of the pressure breaker and the friction cover plate in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a rolling friction optical fiber cutting knife device, which mainly includes a base and a pressure cover, and the pressure cover is connected to the base by a hinge; the base is equipped with a sliding mechanism and a cutting assembly slidably arranged inside the base, wherein whether the sliding mechanism can slide is controlled by a switch, and the sliding mechanism can drive the cutting knife in the cutting assembly to cut; the pressure cover includes a pressing mechanism and a shell, and the pressing mechanism is composed of a pressure pad and a rolling mechanism, wherein the pressing mechanism adopts a roller mechanism to replace the original plane pressing block device and the friction cover plate in the sliding mechanism for rolling and squeezing, thereby driving the sliding mechanism, thereby making the cutting knife cut.

[0007] Preferably, the base of the optical fiber cutting knife device is provided with a clamp assembly for clamping the optical fiber.

[0008] Preferably, the fixture assembly has an optical fiber channel in it, and a marking scale is provided next to the optical fiber channel.

[0009] Preferably, the cutting knife switch is connected to a sliding mechanism in a cavity of the base via a fixing part, the fixing part is controlled by the movement of a movable part in the cutting knife switch, at least two limiting grooves are arranged along the movement direction of the movable part, and during the movement of the movable part, a plunger spring is embedded in the limiting groove.

[0010] Preferably, the sliding mechanism is further provided with a detachable friction cover plate; when in operation, the friction cover plate is squeezed and matched with the rolling mechanism to push the sliding mechanism and drive the cutting knife to move.

[0011] Preferably, the pressing mechanism is connected to the pressure cover via a sleeve and a first spring, and a second spring is arranged inside the sleeve.

[0012] Preferably, a waste outlet of the cutting assembly on the base for cutting the optical fiber is equipped with an optical fiber waste box for collecting waste after the optical fiber is cut.

[0013] Preferably, the rolling mechanism can be implemented by a structure capable of performing circular motion, such as a ball, a roller or a roller.

[0014] The utility model has the following beneficial effects: the utility model discloses a rolling friction optical fiber cutting knife device, comprising a base and a pressure cover, and the base is provided with a cutting knife switch, a cutting assembly and a sliding mechanism, etc. The friction cover plate in the sliding mechanism that contacts the pressure breaker is designed as a detachable mechanism because it needs long-term friction when using the device, and can be replaced after the surface of the friction cover plate is worn, which can effectively ensure the flatness of the surface of the friction cover plate; the pressure cover comprises a pressing mechanism and a shell, and the pressure breaker in the pressing mechanism that contacts the friction cover plate on the sliding mechanism of the base is replaced by a rolling structure instead of a commonly used flat pressing block, which can significantly reduce the friction of the contact surface, and the optical fiber is cut by the pressing mechanism pushing the sliding mechanism to push the cutting knife to cut, especially when cutting the optical fiber, the pressure breaker pops out to press the optical fiber and rubs with the friction cover plate to push the sliding mechanism again, and the rolling mechanism replaces the flat pressing block in the process, which can replace the sliding friction with the rolling friction, which can effectively reduce the friction force and the wear of the friction cover plate during the use of the cutting knife, thereby avoiding the jamming problem of the optical fiber cutting knife device caused by excessive friction and wear of the friction cover plate.

[0029] Specifically, when in use, first place the stripped optical fiber on the clamp assembly 11 for clamping; rotate the pressure cover 2 to fit the base 1 so that the two groups of pressure pads press the optical fiber; push the cutting assembly to slide forward so that the cutting knife forms a scratch on the surface of the optical fiber, and after the cutting assembly forms a scratch on the surface of the optical fiber, the pressing device 21 is triggered, so that the rolling structure 211 on the pressing mechanism 21 squeezes the wear-resistant sheet 141, drives the sliding mechanism 14, and drives the cutting knife 12, thereby achieving the cutting of the optical fiber. Among them, the use of the rolling structure 211 in the process of squeezing the friction cover plate 141 can effectively reduce the friction between the contact surfaces, which can not only reduce the friction between the friction cover plate 141 but also increase the service life of the friction cover plate 141, and can avoid the jamming of the optical fiber cutting knife device caused by the friction and the uneven surface of the friction cover plate 141.

The fixing part is controlled by the movement of the movable part in the cutting knife switch 16, and at least one limiting groove is arranged in the movement direction of the movable part. During the movement of the movable part, a plunger spring is used to be embedded in the limiting groove.

[0039] In order to solve the problem of the optical fiber cutting knife device getting stuck or even stuck due to the large friction between the breaker and the friction cover plate and the wear of the friction cover plate surface, the utility model changes the breaker in the pressing mechanism from a square to a roller mechanism, replaces the sliding friction with rolling friction, and reduces the friction; the structure of the friction cover plate in the sliding mechanism is changed so that it can be replaced at any time, ensuring that the friction cover plate always has a neat plane.
