Description

Technical Field

[0001] The present invention relates to the technical field of packaging structures, and in particular to a glass packaging structure. Background Art

[0002] The packaging process in the field of optical fibers plays a key role in ensuring the stability of optical fiber performance and extending its service life. The most common packaging form currently uses a quartz U-groove as the packaging substrate. The specific operation process is to first place the combined or engraved optical fiber in the U-groove and fix it by dispensing glue; then, place this component in an aluminum metal base and fix it with glue again; then cover the U-groove with a glass cover and apply glue to seal it; finally, cover it with a metal cover and fasten it with screws to complete the entire packaging.

[0003] However, the above-mentioned existing packaging forms have many disadvantages: first, the packaging process is cumbersome and complicated, which consumes a lot of manpower costs and cannot meet the needs of high-efficiency production; second, this packaging method requires the use of multiple materials, including substrates, glass cover plates, metal bases and cover plates, etc., which increases the packaging cost; third, since glue is used many times in the packaging process, this seriously affects the overall heat dissipation effect, and the heat dissipation problem is crucial to the performance and stability of optical fiber equipment. Poor heat dissipation may cause abnormal operation or even damage of the equipment.

[0004] In summary, the existing packaging forms have problems in terms of process, cost and heat dissipation that need to be solved urgently to improve the comprehensive performance of optical fiber packaging; in view of this, we propose a glass packaging structure. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies mentioned in the above background technology and provide a glass packaging structure.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A glass packaging structure is used for packaging optical devices. The packaging structure adopts a flute-shaped tube body and is provided with a glue injection port.

[0008] Preferably, the packaging structure is provided with the glue injection port with a hole number ≥1.

[0009] Preferably, the injection port has a diameter no larger than the inner diameter of the flute-shaped tube, and the injection port is provided with a concave chamfer whose diameter gradually shrinks from the outside to the inside.

[0010] Preferably, when the number of the glue injection ports is ≥2, the glue injection ports are evenly arranged at the central axis of the flute-shaped tube body.

[0011] Preferably, when the number of the glue injection ports is ≥2, the glue injection ports are dispersedly arranged along the central axis of the flute-shaped tube body.

[0012] Preferably, both ends of the flute-shaped tube body are provided with UV curing glue for encapsulating and fixing the optical fiber.

[0013] Preferably, a silicone rubber sealant is provided at the glue injection port for sealing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The glass packaging structure has a simple packaging structure, can effectively reduce packaging costs, improve packaging efficiency, and ensure the consistency of product packaging; the packaging structure can be directly bonded to the U-groove of the fiber laser optical module, avoiding the traditional method of sealing and fixing with glue over a large area, which is beneficial to improving the heat dissipation effect.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0024] The glass packaging structure of this embodiment can package optical devices. Figure 1 The tube body is in a flute shape, and a glue injection port is provided on the packaging structure; in this embodiment, the injection port has a diameter smaller than the inner diameter of the flute body, and the injection port is provided with a concave chamfer whose diameter gradually shrinks from the outside to the inside.

[0025] The working principle of the glass packaging structure of this embodiment is as follows: first, pass one end of the product to be packaged through a flute-shaped glass tube, place the area to be packaged in the flute-shaped glass tube, and adjust the position; be careful not to scratch the optical fiber during the process, then place the flute-shaped glass tube into the corresponding product packaging fixture, adjust the position of the glass tube and the direction of the hole, and observe that the position of the product to be glued is consistent with the hole position; after the adjustment, clamp the optical fibers at both ends; place the fixture on the glue dispensing table, and glue can be dispensed manually or by using an automatic glue dispensing machine. After the glue dispensing is completed, the glue curing operation is completed; after the curing is completed, use silicone rubber to seal the two ends of the glass mouth, and use UV curing glue to seal the glue injection hole to fix the optical fiber, and complete the glue curing operation; it is necessary to ensure that the glue does not exceed the outer diameter of the glass tube.

[0026] Other embodiments can set the number of holes according to the actual dispensing location, such as Figure 2-Figure 5 In the structure shown, the glue injection ports are evenly arranged at the center axis of the flute-shaped tube body or dispersedly arranged along the center axis of the flute-shaped tube body.

[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
