The glue is then left to dry for a period of time, allowing the glue to penetrate the fibers until fully penetrated, and then solidify.

[0003] However, this process method easily causes some optical fibers to be short of glue, and bubbles may enter during the gluing process, thereby affecting the use effect of the finished product. In addition, applying glue to each optical fiber is time-consuming and labor-intensive, resulting in low production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0025] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 The present application provides an optical fiber glue-pouring auxiliary device 100, comprising an air pipe 130, a connector 110, and a pressurizing device 120. The connector 110 comprises a first connecting portion 112 and a second connecting portion 113, wherein a connecting passage 114 is provided between the first connecting portion 112 and the second connecting portion 113. The first connecting portion 112 is connected to the optical fiber product 200 to be bonded, and the second connecting portion 113 comprises a glue injection port 115, which is in communication with the connecting passage 114. The pressurizing device 120 is connected to an air pipe 130, which is connected to the second connecting portion 113 via the air pipe 130, and the air pipe 130 is in communication with the connecting passage 114. The pressurizing device 120 is used to increase the air pressure in the connecting passage 114.

[0027] In the present application, the optical fiber glue filling auxiliary device 100 is connected to the optical fiber product 200 to be bonded using a connector 110, and glue is added through the glue injection port 115 of the connector 110, and then the connector 110 is pressurized by the pressurizing device 120, so that there is a stable air pressure difference on both sides of the glue, and the glue flows along the connecting channel 114 to the optical fiber product 200 to be bonded, thereby achieving the purpose of glue penetrating and filling the gaps between the optical fiber filaments. Moreover, under the action of the air pressure difference, the glue penetrates faster and fills the gaps more fully, and the bubbles in the glue are also squeezed out, so that the sealing effect is better and the connection strength is greater after the glue is cured; in addition, compared with the related art, the present application does not need to be time-consuming and labor-intensive to apply glue to each optical fiber filament separately, but directly fills all optical fiber filaments with glue, and can also ensure the glue penetration effect under pressurized conditions, thereby improving production efficiency and ensuring production quality.

[0028] It should be noted that the connecting channel 114 serves as both a glue and gas flow channel. After glue is added, the increased air pressure causes the glue to flow toward the optical fiber product 200 to be bonded. Furthermore, the connector 110 can be positioned vertically, with the second connecting portion 113 positioned above the first connecting portion 112. In this way, the glue will flow downward under its own weight toward the optical fiber product 200 to be bonded. Combined with the pressure difference, the glue will penetrate the optical fiber bundle 230 more effectively.

[0029] In some embodiments, the pressure device 120 can be an electric pressure device or a manually pressurized hollow rubber device. The blowing principle is similar to that of an ear bulb. The shape of the device can be referred to as Figure 1 ; In addition, in some embodiments, reference Figure 1 The air pipe 130 can be a soft pipe or a hard pipe, for example, a metal pipe, a plastic pipe, etc.

[0030] In some embodiments, reference Figure 1 The optical fiber glue potting auxiliary device includes an air pressure gauge 150, to which the pressurizing device 120 is connected. The air pressure gauge 150 is used to detect the air pressure within the communication channel 114. In this embodiment, the air pressure can be maintained within a certain range based on the indication of the air pressure gauge 150. This ensures that the air pressure within the communication channel 114 remains stable, neither affecting the glue penetration due to excessive air pressure nor causing the joint to collapse due to excessive air pressure.

[0031] Reference Figure 1 and Figure 2In some embodiments, the optical fiber product to be bonded includes a connector 220, the first connecting portion 112 is threadedly connected to the connector 220 of the optical fiber product 200 to be bonded, and a sealing ring 140 is installed between the first connecting portion 112 and the connector 220. In some embodiments, the connector 110 includes a screwing portion 111, the screwing portion 111 is located between the first connecting portion 112 and the second connecting portion 113, and an anti-slip groove 1111 is provided on the outer peripheral wall of the screwing portion 111. In some embodiments, referring to Figure 3 A weight-reducing cavity 1112 is included between the screwing portion 111 and the outer wall of the joint 110 , and the bottom of the weight-reducing cavity 1112 includes a lifting opening 1113 .

[0032] It should be noted that, in practice, the optical fiber product 200 to be bonded can be the optical fiber incident part of a rigid tube endoscope, including a base 210 and a connector 220. The connector 220 is arranged on the base 210, and the base 210 is connected to the tube body 240. The optical fiber bundle 230 passes through the base 210 from the connector 220 and is then distributed along the inside of the tube body 240.

[0033] In the above embodiment, the first connecting portion 112 of the joint 110 can be threadedly connected to the connector 220, which is convenient for disassembly and assembly and has a firm connection. A sealing ring 140 is provided at the connection between the two to avoid air leakage, maintain stable air pressure, and avoid glue leakage, which may cause thread failure. In addition, a screwing portion 111 is provided on the periphery of the joint 110, and anti-slip grooves 1111 are provided to facilitate screwing the joint 110 to connect or disconnect it from the connector 220. The screwing portion 111 is provided with a weight-reducing cavity 1112. While reducing the weight, it can also be connected to other tooling through the lifting opening 1113 at the bottom of the weight-reducing cavity 1112, thereby positioning the joint 110 so that the position of the joint 110 is stable during the glue injection process, and it is not easy to shake, thereby avoiding glue spillage.

[0034] In some embodiments, the anti-slip grooves 1111 include a plurality of convex grooves and concave grooves spaced apart along the circumference, and both the convex grooves and concave grooves extend axially to facilitate screwing the connector 110 with tools such as pliers and wrenches.

[0035] In some embodiments, after the glue injection is completed, the connector 110 is screwed to be removed, but some parts of the internal part of the connector 110 will inevitably have glue adhered to the connector 220 of the optical fiber product 200 to be glued, making it difficult to remove the connector 110. This requires using a tool such as a hook to hook the lifting opening 1113 to assist in pulling the connector 110 upward to facilitate the removal of the connector 110.

[0036] In some embodiments, reference Figure 3The outer wall of the second connection portion 113 includes a plug 1131, which is radially inclined outward in a direction close to the first connection portion 112. In some embodiments, a barb 1132 is formed between the plug 1131 and the outer wall of the second connection portion 113, and the barb 1132 is connected to the trachea 130.

[0037] In the above embodiment, the second connection part 113 includes a plug 1131 that is thinner and thicker, which facilitates the interference fit between the air tube 130 and the second connection part 113. In addition, the second connection part 113 includes a barb 1132, which makes the connection firm and not easily broken by air pressure, thereby increasing air tightness.

[0038] In some embodiments, reference Figure 3 The plug 1131 of the second connecting portion 113 has a bevel, which is easy to insert into the trachea 130, and the tail of the plug 1131 forms a barb 1132, which is firmly connected to the trachea 130.

[0039] Reference Figure 3 In some embodiments, the glue injection port 115 includes a flow-guiding slope 1151 that slopes radially inward toward the second connection portion 113. In some embodiments, the communication channel 114 includes a glue storage buffer chamber 1141, the inner wall of which is a smooth flow-guiding surface. In some embodiments, the glue storage buffer chamber 1141 includes multiple glue storage buffer chambers 1141, and the maximum diameters of the multiple glue storage buffer chambers 1141 decrease as they approach the first connection portion 112.

[0040] In the above embodiment, the glue injection port 115 is funnel-shaped, making it easy to align the glue injection port 115 when pouring glue. The diverting slope 1151 of the glue injection port 115 guides the glue into the glue storage buffer chamber 1141 within the connecting channel 114. If too much glue is added, the glue storage buffer chamber 1141 can pre-hold a portion of the glue to prevent the glue from overflowing from the glue injection port 115, allowing the glue to penetrate into the optical fiber bundle 230 after pressure is applied, thereby regulating the glue flow. In addition, the inner wall of the glue storage buffer chamber 1141 is a smooth diverting surface, which facilitates the flow of glue and prevents glue from accumulating. Furthermore, multiple glue storage buffer chambers 1141 are arranged at intervals or continuously along the connecting channel 114 to enhance the flow regulation function. In addition, the closer the multiple glue storage buffer chambers 1141 are to the optical fiber product 200 to be bonded, the smaller their maximum diameter, i.e., the less they expand, which facilitates focusing the optical fiber bundle 230 and achieving sufficient and rapid glue penetration.

[0041] In particular, the optical fiber glue pouring auxiliary device 100 in the present application may also include other components. Only components related to the present application are listed here, but this does not limit the structure of the optical fiber glue pouring auxiliary device 100.

[0042] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the present application.
