Description

Technical Field

[0001] The patent of this invention belongs to the technical field of batch optical fiber ring curing equipment, and relates to an optical fiber ring ultraviolet curing device and method. Background Art

[0002] Fiber optic ring is an optical device that uses special fiber optic materials to form a ring structure by winding the optical fiber on a skeleton through a curing process and glue bonding according to the relevant volume, optics and vibration requirements. In the process of production and preparation, fiber optic rings can be divided into full skeleton rings, full skeleton fiber optic rings, etc. according to the winding structure. The production process of fiber optic rings requires extreme caution. Usually, the production process of fiber optic rings is winding, (ultraviolet) curing, aging, and testing. Ultraviolet curing usually involves installing the fiber optic ring under a UV light source and rotating it to ensure that the fiber optic ring can fully contact the UV light source and cure. Due to the composition of the glue used in the fiber optic ring system, the light source used in the UV curing process is usually a medium-pressure mercury lamp in the UVA band. In the process of ultraviolet light curing of the fiber optic ring, the fiber optic ring is usually installed on a uniformly rotating installation shaft, and then the ultraviolet light source above the installation shaft is started. After working for a specific period of time, the fiber optic ring is removed to complete the ultraviolet curing process.

[0003] Under mass production conditions, the above UV curing process has obvious shortcomings: The optical power of a single UV light source decays during use, which may lead to differences in curing. The curing effects of different fiber rings vary greatly.

[0004] The sizes of the optical fiber rings are obviously different. The light intensity received by the above-mentioned curing method during the curing process of different batches is obviously different, and the curing effect varies greatly.

[0005] The fixed structure (skeleton) of the wound fiber optic ring varies greatly depending on the product usage scenarios. For example, a full-skeleton fiber optic ring generally does not have a middle through hole and cannot be solidified through a single axis rotation.

[0006] After the fiber wrapping is completed, there must be a pigtail left for subsequent use. At present, during curing, the pigtail is coiled into a circle and fixed on the frame or other attached structures. This operation requires personnel with professional technical conditions. The curing process adds more time costs, and the operation process and actions are complicated, which seriously restricts the efficiency of mass production.

[0007] Traditional UV curing cabinets are bulky and large, taking up a large space. Summary of the invention

[0015] The fiber tray comprises a circular plate, a plug-in shaft and an optical fiber ring frame; the plug-in shaft passes through the circular plate and is fixedly connected thereto, the optical fiber ring frame cooperates with the plug-in shaft, and the plug-in shaft is plugged into a supporting seat of the telescopic tray.

[0016] The optical fiber ring skeleton is a cylinder, and the outer wall of the cylinder is provided with an optical fiber groove for winding the optical fiber; the center of the cylinder is provided with an axial hole to cooperate with the plug-in shaft.

[0017] The ultraviolet light source is fixed at one end of the telescopic arm away from the fiber tray, and the ultraviolet light emitted by the ultraviolet light source is irradiated in the direction of the fiber tray.

[0018] The curing method of the optical fiber ring UV curing device as described above comprises the following steps: S1, fiber winding, winding the optical fiber into the optical fiber groove of the optical fiber ring frame, cleaning the pigtail, and winding it into a ring shape; in this step, no other processing is required; S2, loading, inserting one end of the plug-in shaft of the fiber tray into the support seat and connecting it; in this step, the fiber ring skeleton faces upward; S3, distance adjustment, the gear motor starts to drive the gear to drive the gear plate to rotate, when the gear plate rotates, the limit pin slides along the arc limit groove to drive the telescopic arm to slide along the slide groove on the fixed arm, and the ultraviolet light source on the telescopic arm moves away from or close to the optical fiber ring frame; in this step, the distance between the ultraviolet light source and the optical fiber ring frame is changed to change the irradiation intensity; S4, shielding, the servo motor of the feeding mechanism is started, driving the slider to move along the slide rail, driving the telescopic plate to enter the shielding cover; S5, rotational curing, turning on the ultraviolet light source, starting the drive motor, driving the telescopic disk to rotate and drive multiple ultraviolet light sources to rotate to cure the optical fiber on the optical fiber ring frame; in this step, the fiber disk and the optical fiber ring frame move.

[0020] The gear motor drives the gear to drive the gear plate to rotate, and the gear plate pushes the limit pin to slide along the arc limit groove, thereby driving the telescopic arm to slide along the slide groove on the fixed arm to achieve the telescopic movement of the telescopic arm.

During curing, the pigtail is no longer deliberately coiled into a circle, but only needs to be placed naturally on the circular plate 51, reducing the risk of scrapping during the operation process. Multiple light sources can be added to work simultaneously according to demand, greatly shortening the curing time of the optical fiber ring.
