Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, specifically to an ultraviolet curing lamp for an optical fiber combiner. Background Technology

[0002] In optical fiber communication, based on their functional classification, optical fiber combiners can be divided into two main categories: power combiners and pump combiners.

[0003] Chinese patent ZL202022858193.8 discloses an optical fiber combiner, an aluminum alloy heat sink, and a quartz encapsulation substrate. The heat sink includes a heat sink base and a heat sink cover, and the encapsulation substrate includes an encapsulation base and an encapsulation cover.

[0004] The main factors limiting the performance of fiber optic combiners are stray laser light from coupling losses and waste light from the coating interface, which turn into waste heat inside the device and damage the combiner. After fiber optic splicing, temperature rise detection is required before encapsulation to prevent waste heat from damaging the combiner and reducing product yield.

[0005] During testing, the input and output optical fibers are positioned on the quartz substrate of the test fixture using a dedicated first positioning fixture for temperature rise testing. Input and output optical fibers that fail the temperature rise test need to be re-fused; input and output optical fibers that pass the temperature rise test are then fixed on the quartz packaging substrate using a dedicated second positioning fixture, and finally fixed on the packaging substrate using photocurable adhesive.

[0006] Because the specifications of the quartz packaging substrate vary depending on the configuration of the input and output optical fibers, it is necessary to repeatedly move and position the curing lamp to fix the input and output optical fibers of different specifications, resulting in low work efficiency. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency UV curing lamp for fiber optic combiners, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows.

[0009] A UV curing lamp for an optical fiber combiner includes a base. Vertical arms are mounted on both sides of the upper surface of the base. A crossbeam is mounted on the top of both vertical arms. Two mounting seats are mounted on the upper surface of the crossbeam via a position adjustment mechanism, which allows adjustment of the horizontal position of the mounting seats. A cantilever is mounted on the outer surface of the mounting seat. An adjusting arm is mounted at the end of the cantilever via an angle adjustment mechanism, which allows adjustment of the rotation angle of the adjusting arm. The adjusting arm is used to mount the UV lamp.

[0010] Therefore, the horizontal position of the UV lamp can be adjusted by the position adjustment mechanism, and the rotation angle of the UV lamp can be adjusted by the angle adjustment mechanism. This facilitates the symmetrical setting of the irradiation angle and distance of the two UV lamps, improving the positioning efficiency of the UV lamps and thus increasing production efficiency. The workpiece to be irradiated is located below the cantilever, and the overall structure is simple, compact, and occupies little space.

[0011] Furthermore, the position adjustment mechanism includes a long slot formed on the lower surface of the crossbeam and arranged along its length. A slider is installed on the lower surface of the mounting base, and the slider matches the long slot. A first screw hole is formed on the lower surface of the slider. The position of the mounting base can be fixed by screwing a screw into the first screw hole.

[0012] Furthermore, the angle adjustment mechanism includes a connecting hole at the end of the cantilever, a pin connected to the outer surface of the adjusting arm, and the pin matching the connecting hole. A second screw hole is provided on the outer surface of the cantilever, and the angle of the adjusting arm can be fixed by screwing a screw into the second screw hole.

[0013] Furthermore, the side surface of the beam is provided with symmetrical graduations, and the outer surface of the cantilever is provided with a graduated scale.

[0014] Furthermore, the adjusting arm has an internal mounting groove that matches the UV lamp, and a third screw hole is provided on the outer surface of the adjusting arm. The position of the UV lamp can be fixed by screwing the screw into the third screw hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model, through the setting of a position adjustment mechanism, can adjust the horizontal position of the ultraviolet lamp, and through the setting of an angle adjustment mechanism, can adjust the rotation angle of the ultraviolet lamp, thereby facilitating the symmetrical setting of the irradiation angle and irradiation distance of two ultraviolet lamps, improving the positioning efficiency of the ultraviolet lamp, and thus improving production efficiency.

[0017] 2. This utility model, through the setting of symmetrical scales, facilitates the observation of the movement distance of the two mounting bases. By observing the intersection of the inclined surface of the adjusting arm after rotation and the scale, the rotation angle of the ultraviolet lamp can be observed, thereby improving the positioning accuracy of the ultraviolet lamp.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] like Figure 1-5As shown, a UV curing lamp for an optical fiber combiner includes a base 100. Two upright arms 101 are mounted on both sides of the upper surface of the base 100. A crossbeam 102 is mounted on the top of both upright arms 101. Two mounting seats 103 are mounted on the upper surface of the crossbeam 102 via a position adjustment mechanism 200, which can adjust the horizontal position of the mounting seats 103. A cantilever 104 is mounted on the outer surface of the mounting seat 103. An adjusting arm 105 is mounted at the end of the cantilever 104 via an angle adjustment mechanism 300, which can adjust the rotation angle of the adjusting arm 105. The adjusting arm 105 is used to mount the UV lamp 106.

[0028] In use, the base 100 is first installed at the designated work station. Then, the horizontal position of the two ultraviolet lamps 106 is adjusted by the position adjustment mechanism 200. Then, the rotation angle of the ultraviolet lamps 106 is adjusted by the angle adjustment mechanism 300. This allows for the portable and symmetrical setting of the irradiation angle and irradiation distance of the two ultraviolet lamps 106, improving the positioning efficiency of the ultraviolet lamps 106 and thus improving production efficiency.

[0029] Specifically, the position adjustment mechanism 200 includes a long groove 201 formed on the lower surface of the crossbeam 102 and arranged along its length. A slider 202 is installed on the lower surface of the mounting base 103, and the slider 202 matches the long groove 201. A first screw hole 203 is formed on the lower surface of the slider 202. The position of the mounting base 103 can be fixed by screwing a screw into the first screw hole 203. When it is necessary to adjust the horizontal position of the UV lamp 106, simply loosen the screw from the first screw hole 203 to separate the end of the screw from the lower surface of the crossbeam 102. Then, the sliding mounting base 103 can be used to adjust the horizontal position of the UV lamp 106. After the position is adjusted, tighten the screw into the first screw hole 203 so that the end of the screw abuts against the lower surface of the crossbeam 102, thereby completing the purpose of adjusting the horizontal position of the UV lamp 106. Furthermore, through the limiting sliding action of the slider 202 and the long groove 201, the installation angle of the mounting base 103 can be limited, thereby improving the positional accuracy of the UV lamp 106.

[0030] Specifically, the angle adjustment mechanism 300 includes a connecting hole 301 at the end of the cantilever 104, a pin 302 connected to the outer surface of the adjusting arm 105, and the pin 302 matching the connecting hole 301. A second screw hole 303 is provided on the outer surface of the cantilever 104. The angle of the adjusting arm 105 can be fixed by screwing a screw into the second screw hole 303. When it is necessary to adjust the irradiation angle of the ultraviolet lamp 106, the screw can be loosened from the second screw hole 303 first, so that the end of the screw is separated from the surface of the pin 302. At this time, the pin 302 is released from fixation, and it can be rotated to adjust the angle of the ultraviolet lamp 106. After adjustment, the screw is tightened into the second screw hole 303 so that its end abuts against the outer surface of the pin 302.

[0031] Specifically, the side surface of the crossbeam 102 is provided with symmetrical scales 400, and the outer surface of the cantilever 104 is provided with a scale 401. The symmetrical scales 400 facilitate the observation of the movement distance of the two mounting bases 103. By observing the intersection of the inclined surface of the adjusting arm 105 after rotation with the scale 401, the rotation angle of the ultraviolet lamp 106 can be observed, which facilitates the precise and symmetrical setting of the irradiation angle and irradiation distance, thereby improving the positioning accuracy of the ultraviolet lamp 106.

[0032] Specifically, the adjusting arm 105 has an internal mounting groove 500, and the ultraviolet lamp 106 is matched with the mounting groove 500. The outer surface of the adjusting arm 105 has a third screw hole 501. The position of the ultraviolet lamp 106 can be fixed by screwing the screw into the third screw hole 501. The mounting groove 500 and the third screw hole 501 facilitate the replacement of the ultraviolet lamp 106.

[0033] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
