Description

Technical Field

[0001] This utility model relates to the field of optical fiber production technology, specifically to a high-efficiency optical fiber ring ultraviolet curing box. Background Technology

[0002] Fiber optic ring UV curing chambers are typically used in the fiber optic manufacturing process, especially in fiber connection, cladding, or coating stages. These chambers utilize UV ​​light for curing, enabling coating materials or adhesives to cure rapidly within a short time through UV irradiation, thereby improving production efficiency and product quality.

[0003] Fiber optic ring curing refers to using a laser of a specific wavelength and intensity to focus on the surface of a fiber optic ring's photocurable material, causing it to solidify in a sequence from point to line and from line to surface, forming a fiber optic ring layer. Then, the fiber optic ring layer is moved vertically by the height of one layer, and the fiber optic rings of adjacent layers are cured. By stacking these layers, a three-dimensional entity can be formed, which is used for curing objects inside a curing box.

[0004] When the fiber optic ring is cured inside the curing chamber, it is necessary to fix the fiber optic ring. Generally, clamping is used for fixing. However, clamping not only cannot guarantee stability, but the clamped part of the fiber optic ring will be blocked by the clamping mechanism, thus affecting the ultraviolet light and causing local curing abnormalities of the fiber optic ring.

[0005] Therefore, this application is hereby submitted. Utility Model Content

Detailed Implementation

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane". Example Please refer to Figures 1 to 4 As shown, this embodiment provides a high-efficiency fiber optic ring UV curing chamber, including a chamber body 10, which is sealed and has a door 11. Multiple UV lamps 12 are evenly spaced in a ring inside the chamber body 10. The chamber body also includes a support mechanism, comprising a base plate 20, multiple support plates 21, and a power assembly. The base plate 20 is coaxially positioned within the ring formed by all the UV lamps 12. The power assembly is located in the center of the base plate 20. All the support plates 21 are arranged in a ring around the power assembly to form a support ring. The support plates 21 and the base plate 20 slide radially along the support ring. The power assembly enables all the support plates 21 to slide synchronously with the base plate 20.

[0023] The high-efficiency fiber optic ring UV curing chamber disclosed in this embodiment forms a sealed curing environment by setting up a chamber body 10 and a UV lamp 12. A supporting mechanism is provided, comprising a base plate 20, multiple support plates 21, and a power assembly. The support plates 21 slide against the base plate 20 to form a supporting ring, with the sliding direction being radial. The power assembly synchronously drives all the support plates 21 to slide, thereby reducing or increasing the outer diameter of the supporting ring. In use, the outer diameter of the supporting ring is first reduced to its minimum, and then the fiber optic ring to be cured is placed over the supporting ring. The power assembly then drives the support plates 21 to slide outward, gradually increasing the outer diameter of the supporting ring until the fiber optic ring is rounded and fixed. At this point, the area on the outer wall of the fiber optic ring to be cured is fully exposed to the UV lamp, thus avoiding localized curing abnormalities caused by clamping and obstruction. Through the cooperation of the above features, this high-efficiency fiber optic ring UV curing chamber effectively solves the problems of unstable clamping during fiber optic ring curing and the tendency for localized curing abnormalities due to clamping and fixing.

[0024] To further explain the specific structure of the sliding fit between the support plate 21 and the base plate 20, the base plate 20 has multiple radially spaced grooves 201, and sliding columns 202 are slidably connected within the grooves 201. The axis of the sliding column 202 is perpendicular to the base plate 20. The support plate 21 corresponds to and is connected to the sliding column 202. When all the sliding columns 202 are located at the outer ends of the grooves 201, the outer diameter of the support ring is smaller than the inner diameter of the lamp ring formed by all the ultraviolet lamps 12.

[0025] To further explain the specific structure of the power assembly, the power assembly includes a motor 22, a rotating cylinder 23, and multiple connecting rods 24; the rotating cylinder 23 is coaxially rotatably connected to the base plate 20, the rotating cylinder 23 is drive-connected to the motor 22, and the motor 22 is fixedly connected to the housing 10; one end of the connecting rod 24 is hinged to the outer side wall of the rotating cylinder 23, and the other end is hinged to the support plate 21, and the angle between the connecting rod 24 and the side wall of the rotating cylinder 23 is an acute angle.

[0026] With the above setup, the motor 22 drives the rotating cylinder 23 to rotate, thereby driving the connecting rod 24 to rotate and gradually change its angle, thereby pushing the sliding column 202 in the sliding groove 201 to slide along the direction of the sliding groove 201, thereby driving the support plate 21 to slide.

[0027] To facilitate the application of force, the end of the connecting rod 24 away from the rotating cylinder 23 is bent toward the rotating cylinder 23, and the curvature of the connecting rod 24 is less than the curvature of the outer wall of the rotating cylinder 23.

[0028] To increase the range of variation of the outer diameter of the support ring, the slide groove 201 includes an inner slide groove 2011 and an outer slide groove 2012, which are arranged alternately; the support plate 21 includes an inner support plate 211 and an outer support plate 212, the inner support plate 211 corresponds one-to-one with the inner slide groove 2011 and is slidably engaged by the slide column 202, and the outer support plate 212 corresponds one-to-one with the outer slide groove 2012 and is slidably engaged by the slide column 202; the two sides of the outer support plate 212 in the length direction are respectively attached to the outer wall of one side of the length direction of two adjacent inner support plates 211; the connecting rod 24 corresponds one-to-one with the inner support plate 211 and is hinged.

[0029] With the above setup, the inner support plate 211 supports the outer support plate 212. When the plate is retracted, the two do not obstruct each other, and the minimum outer diameter of the support ring will not be affected by the number of plates or the length of the plates.

[0030] To accommodate the shape of the fiber optic ring, the support plate 21 is an arc plate, and the curvature of the outer support plate 212 is less than the curvature of the inner support plate 211.

[0031] Preferably, in order to ensure that the supporting ring is always a near-circular surface, the middle part of the inner wall of the support plate 21 is hinged to the sliding column 202, and a reset torsion spring is provided at the hinge. When the reset torsion spring is in its natural state, the support plate 21 is perpendicular to the corresponding sliding groove 201.

[0032] In order to optimize the area occupied when the support plate 21 is retracted, when all the sliding columns 202 are located at the inner end of the sliding groove 201, all the inner support plates 211 are spliced ​​to form an inner ring, and all the outer support plates 212 are spliced ​​to form an outer ring.

[0033] To further optimize the area occupied when the support plate 21 is retracted, the outer diameter of the inner ring is the same as the inner diameter of the outer ring, so that the inner wall of the outer support plate 212 fits against the outer wall of the inner support plate 211.

[0034] To further explain the transmission connection structure between the rotating cylinder 23 and the motor 22, a gear ring is coaxially protruded from the inner wall of the rotating cylinder 23; the output shaft of the motor 22 is coaxially disposed within the gear ring, and an output gear 221 is coaxially fitted onto the output shaft of the motor 22. The output gear 221 meshes with the gear ring through a transmission gear 222 to form a planetary gear set.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
