Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber collimator manufacturing, in particular to a collimator packaging tool. Background Art
[0002] A fiber collimator is an optical component used to convert a diverging optical beam from an optical fiber into a parallel beam, thereby achieving beam alignment and long-distance transmission within the optical path. Typically consisting of a lens, glass tube, capillary, and optical fiber inserted into the capillary, it effectively improves beam transmission efficiency and provides flexibility in optical path design. It is widely used in optical communications, optical sensing, laser processing, and other fields.
[0003] like Figure 1 As shown in the figure, during collimator manufacturing, the outer glass tube needs to be encapsulated in a metal sleeve. The metal sleeve facilitates welding the collimator to the metal mounting base in the application. However, traditional packaging methods require dispensing heat-curing glue into the gap between the glass tube and the metal sleeve. If excess glue flows onto the optical fiber and eventually solidifies on the fiber, it can easily cause light leakage, generate waste heat, and pose a significant risk of burning the collimator. Utility Model Content
[0004] The utility model aims to provide a collimator packaging tool which can prevent glue from contaminating optical fibers.
[0005] To achieve the above objectives, the technical solution of the present utility model is as follows.
[0006] A collimator packaging tool comprises a base, wherein a plurality of corresponding first bearing grooves and second bearing grooves are provided along its length on one side of its upper surface along its width direction, wherein the first bearing grooves and the second bearing grooves extend along the width direction, and an escape groove is provided between the first bearing grooves and the second bearing grooves. A glue storage groove is provided on the upper surface of the base, which is connected to the second bearing groove, and the lowest point of the glue storage groove is lower than the lowest point of the second bearing groove. Along the width direction, the glue storage groove and the escape groove are located on both sides of the second bearing groove. A fiber supporting area is provided on the other side of the upper surface of the base along its width direction, and a boss is provided on the upper surface of the base between the fiber supporting area and the glue storage groove.
[0007] It can be seen that the optical fiber is supported by the boss and the excess optical fiber is placed on the optical fiber supporting area. Therefore, when the metal sleeve is placed on the first bearing groove, the second bearing groove and the avoidance groove for curing, the excess glue can flow to the glue storage groove, which can prevent the glue from contaminating the optical fiber and preventing the optical fiber from burning due to waste heat, thereby improving product quality and life, and allowing multiple collimators to be thermally cured at the same time to improve efficiency. The setting of the avoidance groove makes it easy to pry out the cured collimator from the first bearing groove and the second bearing groove.
[0008] Furthermore, the first bearing groove and the avoidance groove are coaxially arranged and have the same radius.
[0009] Furthermore, the base is entirely made of Teflon, Bakelite, high-temperature resistant nylon or metal. When the base is entirely made of metal, its working surface is coated with a release film.
[0010] Furthermore, the base is arranged in an inclined structure with the left side lower and the right side higher.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows.
[0012] The utility model supports the optical fiber by means of the boss and places the excess optical fiber on the optical fiber supporting area. Therefore, when the metal sleeve is placed on the first bearing groove and the avoidance groove for curing, it can avoid glue contamination of the optical fiber and avoid burning of the optical fiber due to waste heat, thereby improving product quality and service life. It can also allow for thermal curing of multiple collimators at the same time, thereby improving efficiency. The arrangement of the avoidance groove facilitates the removal of the cured collimator from the first bearing groove and the second bearing groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

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. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Here, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.
[0020] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, the terms "first" and "second" may explicitly or implicitly include one or more of the features.
[0021] like Figure 1-4 As shown, a collimator packaging tool includes a base 100. A plurality of corresponding first bearing grooves 101 and second bearing grooves 102 are provided on the upper surface of the base 100 along one side of its width direction 1 and along its length direction 2. The first bearing grooves 101 and the second bearing grooves 102 extend along the width direction 1, and an escape groove 103 is provided between the first bearing grooves 101 and the second bearing grooves 102. A glue storage groove 104 is provided on the upper surface of the base 100. The glue storage groove 104 communicates with the second bearing groove 102, and the lowest point of the glue storage groove 104 is lower than the lowest point of the second bearing groove 102. Along the width direction 1, the glue storage groove 104 and the escape groove 103 are located on either side of the second bearing groove 102. A fiber supporting area 105 is provided on the other side of the upper surface of the base 100 along the width direction 1. A boss 106 is provided on the upper surface of the base 100 between the fiber supporting area 105 and the glue storage groove 104.
[0022] During use, the glass tube 01 is first inserted into the metal sleeve 02, with the glass tube 01 extending 1 to 2 mm from the front end of the metal sleeve 02. Glue is then applied at the junction of the glass tube 01 and the metal sleeve 02, allowing the heat-curing glue to penetrate the gap between the glass tube 01 and the metal sleeve 02. The glass tube 01 is then pushed into the metal sleeve 02, with the front ends of the glass tube 01 and the metal sleeve 02 aligned. Preferably, the glass tube 01 and the metal sleeve 02 are of the same length, both 15 to 20 mm, so that both ends of the glass tube 01 and the metal sleeve 02 are flush. The collimator with the metal sleeve 02 is then placed on the first bearing groove 101, the second bearing groove 102, and the avoidance groove 103, while the optical fiber 03 is horizontally placed on the boss 106, and the tail of the optical fiber 03 is coiled and placed on the optical fiber support area 105. Subsequently, the entire collimator packaging tool is sent into an oven for heat curing. During the curing process, excess glue flows onto the second bearing groove 102 and into the glue storage groove 104. Since the optical fiber 03 is in a suspended position, the glue can be prevented from flowing onto the optical fiber 03, preventing the optical fiber 03 from being burned by waste heat, thereby improving product quality and lifespan. It also allows for the simultaneous thermal curing of multiple collimators, improving efficiency. After the thermal curing is completed, a screwdriver is used to knock out the packaged collimator from the avoidance groove 103. It also allows for the simultaneous thermal curing of multiple collimators, improving efficiency.
[0023] Small-diameter collimators can be placed in the first bearing groove 101, the second bearing groove 102, and the avoidance groove 103 for thermal curing, while large-diameter collimators can be placed directly in the glue storage groove 104 for thermal curing, thus meeting the packaging requirements of collimators of different specifications. When a small-diameter collimator is placed in the first bearing groove 101, the second bearing groove 102, and the avoidance groove 103, the optical fiber 03 is flush with the boss 106; when a large-diameter collimator is placed in the glue storage groove 104, its optical fiber 03 remains flush with the boss 106, thus preventing excessive bending of the optical fiber 03 and contact with the glue.
[0024] Specifically, the first bearing groove 101 and the avoidance groove 103 are coaxially arranged and have the same radius. When the small diameter collimator is placed on the first bearing groove 101 and the avoidance groove 103, it can fit completely with the collimator, which is beneficial to reduce the amount of glue on the outer surface of the metal sleeve 02 and reduce the workload of subsequent surface cleaning.
[0025] Specifically, the base 100 is made of Teflon, Bakelite, high-temperature resistant nylon or metal. When the base 100 is made of metal, its working surface is coated with a release film, which is paraffin or a spray-type release agent, which can prevent the glue from sticking the collimator to the base.
[0026] Specifically, the base 100 is set as an inclined structure with the left side lower and the right side higher. The setting of the inclined structure can improve the fluidity of the glue between the glass tube 01 and the metal sleeve 02, so that the glue can completely bond the glass tube 01 and the metal sleeve 02, and allow excess glue to flow along the second supporting groove 102 to the glue storage groove 104, and try to avoid the glue from flowing into the first supporting groove 101 and accumulating, thereby causing contamination to the lens.
[0027] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
