Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for fiber optic array production, specifically to a fiber optic array tail glue filling and fixing device. Background Technology

[0002] A fiber optic array typically includes a substrate, a cover plate, and optical fibers. The cover plate is mounted on the substrate, and a receiving groove is provided between the substrate and the cover plate. The bare fiber portion is placed in the receiving groove and fixed with adhesive. A stepped portion is provided at the rear end of the substrate, and the wrapped portion of the optical fiber is placed on the stepped portion and extends rearward. To fix the substrate and optical fiber, tail adhesive is generally filled between the rear end of the substrate and the optical fiber.

[0003] Existing adhesive filling methods require filling from both sides of the substrate twice, which is not only time-consuming and labor-intensive, but also affects dispensing efficiency, especially in mass production where it can severely reduce production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fiber optic array tail glue filling and fixing device with a simple structure and high dispensing efficiency.

[0005] To achieve the above objectives, this utility model provides a fiber optic array tail glue filling and fixing device, including a base and a dispensing plate. The base is provided with a first supporting surface; the dispensing plate is provided on one side of the base, and the dispensing plate is provided with a stop portion, a second supporting surface and a recessed portion. The stop portion intersects with the first supporting surface, and the upper part of the stop portion is higher than the first supporting surface, the second supporting surface is higher than the stop portion, and the recessed portion is provided between the stop portion and the second supporting surface, and the recessed portion is recessed in the stop portion and the second supporting surface.

[0006] As can be seen from the above solution, by setting a first supporting surface to support the substrate of the fiber array; by setting a stop portion to abut against the rear end face of the fiber array substrate; and by setting a recessed portion to reserve sufficient space for filling the end adhesive, during dispensing, the operator only needs to fill the end adhesive once at the rear end of the substrate and in the recessed portion to fix the fiber and the substrate. Compared with the prior art, it is not necessary to dispense adhesive on the front and back sides separately, which helps to save processes and time, improve dispensing efficiency, and quickly achieve mass production. Moreover, using this utility model for dispensing can ensure the consistency of the adhesive thickness of the fiber array and the consistency of the product tensile strength. This utility model also has the advantages of simple structure and convenient operation.

[0007] A further option is to set the stop portion perpendicular to the first support surface.

[0008] A further option is that the recess includes a slope that extends upward from the upper part of the stop towards the second support surface.

[0009] A further embodiment is that the recessed portion includes an arc surface, the lower part of which is connected to the upper part of the stop portion, the upper part of which is connected to the second support surface, and the middle part of which is recessed towards the inside of the dispensing plate.

[0010] A further solution is to install double-sided adhesive on the stop.

[0011] As can be seen from the above solution, by setting double-sided adhesive, it can be used to bond the substrate of the fiber array, so as to fix the fiber array and ensure that no gap is generated between the substrate and the lower edge of the recess, thus avoiding the leakage of the tail adhesive.

[0012] A further solution is to provide a clearance groove between the base and the dispensing plate to avoid the double-sided adhesive, with the clearance groove located between the first supporting surface and the stop portion.

[0013] As can be seen from the above solution, by setting the clearance groove, it is convenient to apply and remove the double-sided tape.

[0014] A further solution is to provide a protrusion between the base and the dispensing plate, through which the base and the dispensing plate abut against each other.

[0015] A further embodiment is that the base is also provided with a support part, the upper surface of the support part is lower than the first support surface, the protrusion is disposed between the first support surface and the support part, and the glue plate is disposed on the support part and abuts against the protrusion.

[0016] A further embodiment is that the fiber array tail glue filling and fixing device also includes a stop block and a first locking fastener. The stop block is connected to the side wall of the support part through the first locking fastener, and the stop block abuts against the side wall of the glue dispensing plate.

[0017] A further option is that the fiber array tail glue filling and fixing device also includes a second locking fastener, through which the glue dispensing plate is fixed to the support. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0025] See Figure 1 The fiber array 1 provided in this embodiment includes a substrate 11, a cover plate 12, and optical fibers 13. The substrate 11 has multiple receiving grooves 111 extending in a front-to-back direction and arranged laterally. A stepped portion 112 is provided at the rear end of the substrate 11, with its upper surface lower than the bottom of the receiving groove. The optical fiber 13, along its extension direction, includes a bare fiber portion 131 and a wrapping portion 132. The bare fiber portion 131 is disposed within the receiving groove 111, and the wrapping portion 132 is disposed above the stepped portion 112 and extends rearward. The cover plate 12 is disposed on the substrate 11 and covers the receiving grooves 111. The bare fiber portion 131 of the optical fiber 13 is fixed to the substrate 11 and the cover plate 12 by adhesive. The bare fiber portion 131 and the partially wrapped portion 132 are fixed to the stepped portion 112 by tail adhesive (not shown in the figure). Of course, the tail adhesive can also be bonded to the rear wall of the cover plate 12 simultaneously.

[0026] See Figures 2 to 6 The fiber optic array tail glue filling and fixing device provided in this embodiment includes a base 2 and a glue dispensing plate 3.

[0027] The base 2 is designed with an approximately "L" shape. Horizontally, from left to right, the base 2 has a first supporting surface 21, a protrusion 22, and a supporting portion 23. The first supporting surface 21 is the top wall of the base 2. The supporting portion 23 is located on one side of the first supporting surface 21. Vertically, the upper surface of the supporting portion 23 is lower than the first supporting surface 21. The protrusion 22 is located on the vertical wall between the top wall of the base 2 and the supporting portion 23, and protrudes horizontally towards the supporting portion 23. Vertically, the protrusion 22 is located close to the upper surface of the supporting portion 23, and a clearance groove 24 is formed above the protrusion 22, which is recessed downwards from the first supporting surface 21.

[0028] The dispensing plate 3 is disposed on one side of the base 2, preferably on the support portion 23, and the side wall of the dispensing plate 3 abuts against the protrusion 22. In the vertical direction, the top wall of the dispensing plate 3 is slightly higher than the first support surface 21. The dispensing plate 3 is provided with a stop portion 31, a second support surface 32, and a recessed portion 33. The stop portion 31 is disposed on the side wall of the dispensing plate 3 and intersects with the first support surface 21; in this embodiment, the stop portion 31 is perpendicular to the first support surface 21. The upper edge of the stop portion 31 is slightly higher than the first support surface 21, and the second support surface 32 is higher than the upper edge of the stop portion 31, and the second support surface 32 is parallel to the first support surface 21. The recessed portion 33 is disposed between the upper edge of the stop portion 31 and the second support surface 32, and the recessed portion 33 is recessed into the stop portion 31 and the second support surface 32. Specifically:

[0029] In one embodiment, the recess 33 includes a slope 331 that extends obliquely upward from the upper edge of the stop portion 31 toward the second support surface 32, so that the dispensing plate 3 has a chamfer on the side near the first support surface 21, leaving enough space for the filling of the tail glue 6.

[0030] In another embodiment, the recessed portion 33 includes an arc surface, the lower edge of which is connected to the upper edge of the stop portion 31, the upper edge of which is connected to the edge of the second supporting surface 32, and the middle part of the arc surface is recessed towards the inside of the dispensing plate 3 to reserve sufficient space for the filling of the tail glue 6.

[0031] When the fiber array 1 is mounted on the fixing device of this embodiment, the substrate 11 is mounted on the first supporting surface 21, and the rear end face of the substrate 11 abuts against the stop portion 31 to seal the lower edge of the recessed portion 33 and prevent subsequent glue leakage. At this time, the wrapping portion 132 of the fiber 13 spans over the recessed portion 33 and is mounted on the second supporting surface 32. The wrapping portion 132 may or may not be in direct contact with the second supporting surface 32, which is not limited here.

[0032] When filling the tail adhesive 6, it is only necessary to fill it on the front side of the fiber array 1. The tail adhesive 6 will fill the stepped portion 112 of the substrate 11 and the periphery of the fiber 13. Since the recessed portion 33 is located below the wrapping portion 132, the tail adhesive 6 will automatically fall into the recessed portion 33 and then wrap the fiber 13 from all sides, ensuring that the fiber 13 is firmly connected to the substrate 11 and the cover plate 12. During this process, there is no need to flip the fiber array 1, which helps to save the flipping process and dispensing time and improve dispensing efficiency.

[0033] Furthermore, a double-sided adhesive 4 is provided on the stop portion 31, extending from the stop portion 31 into the recessed portion 33 and towards the second supporting surface 32. The double-sided adhesive 4 on the stop portion 31 can adhere to the substrate 11 to fix the substrate 11 and seal the gap between the substrate 11 and the stop portion 31. The double-sided adhesive 4 extends to the second supporting surface 32, allowing it to be easily and quickly peeled off and replaced with a new one when needed.

[0034] Furthermore, a clearance groove 24 is provided between the base 2 and the dispensing plate 3 to avoid the double-sided adhesive 4. The clearance groove 24 is located between the first supporting surface 21 and the stop part 31, which facilitates the worker to apply and remove the double-sided adhesive 4.

[0035] The base 2 and the dispensing plate 3 abut against each other via the protrusion 22 to fix the position of the dispensing plate 3. In this embodiment, the protrusion 22 is provided on the base 2; in other embodiments, the protrusion 22 may also be provided on the side wall of the dispensing plate 3.

[0036] In this embodiment, the base 2 is placed on a horizontal working surface, the support portion 23 is disposed on one side of the first support surface 21, and the dispensing plate 3 is disposed on the support portion 23 and abuts against the protrusion 22. In other embodiments, both the base 2 and the dispensing plate 3 can be placed directly on the working surface.

[0037] The fiber optic array tail glue filling and fixing device of this embodiment also includes a stop block 5 and two first locking fasteners (not shown in the figure). The stop block 5 is connected to the side wall of the support part 23 by the first locking fasteners. Specifically, two screw holes 231 are provided on the side wall of the support part 23, and two through holes 51 are provided on the stop block 5. The first locking fasteners can be screws, which pass through the through holes 51 and are connected to the screw holes 231. At this time, the upper part of the stop block 5 is higher than the upper surface of the support part 23 and abuts against the side wall of the glue dispensing plate 3, which is used to fix the glue dispensing plate 3 to the base 2 and prevent the two from separating accidentally.

[0038] In other embodiments, the fiber optic array tail adhesive filling and fixing device further includes a second locking device, through which the adhesive dispensing plate 3 is fixed to the support portion 23. Specifically, a screw hole 231 is provided on the upper surface of the support portion 23, and a through hole 51 is provided vertically through the adhesive dispensing plate 3. The second locking device passes through the through hole 51 and is connected to the screw hole 231 to directly lock the adhesive dispensing plate 3 to the support portion 23. The first locking device can be a screw, preferably a countersunk screw, to ensure that the upper part of the first locking device is lower than the top wall of the adhesive dispensing plate 3.

[0039] In summary, this invention provides a first supporting surface 21 to support the substrate 11 of the fiber array 1; a stop portion 31 to abut against the rear end face of the substrate 11; and a recessed portion 33 to provide sufficient space for the filling of the tail adhesive 6. During dispensing, the operator only needs to fill the rear end of the substrate 11 and the recessed portion 33 once with the tail adhesive 6 to fix the fiber 13 and the substrate 11. Compared with the prior art, it eliminates the need for dispensing adhesive on both the front and back sides, which helps to save processes and time, improve dispensing efficiency, and quickly achieve mass production. Moreover, using this invention for dispensing can ensure the consistency of the dispensing thickness of the fiber array 1 and the consistency of the product tensile strength.
