Description

Technical Field

[0001] This application relates to the field of optical fiber ferrule technology, and in particular to an optical fiber ferrule glue injection and bubble removal device. Background Technology

[0002] Fiber optic connectors are detachable and categorized fiber optic connectors that make the connection, switching, and scheduling of optical channels more flexible, and are suitable for the debugging and maintenance of optical communication systems. In the production process of fiber optic connectors, adhesive is first injected into the fiber optic ferrule, then the optical fiber is inserted into the ferrule, and finally the adhesive is cured to fix the optical fiber in the ferrule, ultimately forming the fiber optic connector.

[0003] Before injecting adhesive into the fiber optic jack, the adhesive needs to be mixed, and then injected into the jack. Air bubbles may be present in the adhesive during storage, mixing, and injection. These air bubbles not only cause uneven stress on the fiber optic cable within the ferrule but also lead to loosening of the fiber optic cable, severely impacting the reliability and stability of the fiber optic connector and reducing its overall product quality.

[0004] In the past, specific techniques were used to inject adhesive into the ferrule to reduce air bubbles. However, existing techniques cannot guarantee that the adhesive injected into the ferrule is free of air bubbles. Specific techniques are required for adhesive injection, which heavily relies on the operator's skill level; different people will produce different results, and human error is a significant factor, making it impossible to guarantee that the adhesive in the ferrule is completely free of air bubbles.

[0005] Because the product structure is very small, there is no good way to remove air bubbles from the ferrule after it has been glued, which makes it impossible to remove the air bubbles left inside the ferrule.

[0006] Chinese patent application number 2021215328940 discloses a device for eliminating air bubbles in the adhesive inside a ferrule. The device comprises three cross-shaped plates, arranged sequentially from top to bottom as a top cross-shaped plate, a middle cross-shaped plate, and a bottom cross-shaped plate. These plates are connected by a central shaft. A ferrule is inserted through each of the four ends of the middle cross-shaped plate, with each ferrule's two ends abutting against the adjacent sides of the top and bottom cross-shaped plates. This application aims to reduce the presence of air bubbles (in addition to adhesive) inside the ferrule after curing, especially beneficial for workers in the optical communication industry when producing products such as patch cords.

[0007] Although the aforementioned device for eliminating air bubbles in the adhesive within the ferrule is installed on a centrifugal device, using centrifugation to expel the air bubbles from the adhesive in the fiber optic ferrule, the centrifugal angle of the ferrule remains constant within the centrifugal device. The air bubbles in the adhesive are further impeded by the obstruction of the fiber optic ferrule wall, affecting the expulsion effect. Furthermore, to achieve a seal at the bottom of the ferrule, during the bubble removal process, the adhesive inside the fiber optic ferrule is flung out due to centrifugal force, resulting in adhesive loss within the fiber optic ferrule and impacting the product quality of the optical connector.

[0008] It is evident that how to completely remove air bubbles from the adhesive in the fiber optic jack without causing adhesive loss, improve the degassing effect, and ensure product quality are urgent technical problems that need to be solved. Summary of the Invention

[0009] This application provides a fiber optic ferrule injection and bubble removal device, which aims to solve the technical problem in the prior art of how to completely remove air bubbles from the glue in the fiber optic ferrule without causing glue loss, thereby improving the bubble removal effect and ensuring product quality.

[0014] The tray assembly includes a core support and an anti-overflow pad;

[0015] The ferrule bracket has several limiting holes, which limit the radial direction of the fiber optic ferrule.

[0016] The anti-overflow pad is in contact with the bottom of the optical fiber ferrule inside the limiting hole;

[0017] When the centrifuge host is running, it drives the rotor support to rotate, and the anti-overflow pad forms a seal with the bottom of the optical fiber ferrule;

[0018] The rotation axis of the tray assembly relative to the rotor support is perpendicular to the rotation center axis of the rotor support;

[0019] The center of gravity of the tray assembly is lower than the height of the rotation axis;

[0022] Furthermore, the material of the spill-proof pad is a silicone pad.

[0023] Furthermore, the tray assembly also includes a support plate, and the spill-proof pad is disposed between the insert bracket and the support plate.

[0024] Furthermore, a clearance groove is provided between the insert bracket and the support plate, and the anti-overflow pad is disposed in the clearance groove.

[0025] Furthermore, the connector is shaft-shaped and disposed on both sides of the tray assembly, and the tray assembly has slots on both sides that are adapted to the connector.

[0026] Furthermore, the tray assembly is equipped with snap-fit ​​members at both ends, and the snap-fit ​​slot is disposed on the snap-fit ​​member.

[0027] Furthermore, the side wall of the end of the card slot that communicates with the outside of the card connector is provided with a guide slope.

[0028] Furthermore, there are four tray assemblies, which are mounted on the four sides of the rotor support in the same manner.

[0029] Furthermore, the rotor support has a centrally symmetrical structure, and a locking hole is provided in the center of the rotor support. The rotor support is installed at the output end of the centrifuge host through the locking hole.

[0030] The beneficial effects achieved by this application are:

[0031] This application discloses a fiber optic ferrule injection and defoaming device, comprising a centrifuge unit, a rotor support, and a tray assembly. The rotor support is equipped with connectors and is mounted on the output end of the centrifuge unit. The tray assembly is rotatably mounted on the rotor support via the connectors. The tray assembly includes a ferrule holder and an anti-overflow pad. The ferrule holder has several limiting holes that limit the radial direction of the fiber optic ferrule. The anti-overflow pad is in contact with the bottom of the fiber optic ferrule within the limiting holes. When the centrifuge unit operates, it drives the rotor support to rotate, forming a seal between the anti-overflow pad and the bottom of the fiber optic ferrule. The rotation axis of the tray assembly relative to the rotor support is perpendicular to the rotation center axis of the rotor support. The center of gravity of the tray assembly is lower than the height of the rotation axis. The axis of the limiting holes is parallel to the perpendicular line of the rotation axis passing through the center of gravity of the tray assembly. When the centrifuge operates, it drives the rotor support to rotate. Under the action of centrifugal force, the tray assembly rotates relative to the rotor support, ultimately making the axis of the limiting hole parallel to the direction of the resultant force of centrifugal force and gravity on the tray assembly. This, in turn, makes the axis of the fiber optic ferrule parallel to the direction of the resultant force of centrifugal force and gravity on the tray assembly, allowing air bubbles in the adhesive within the fiber optic ferrule to escape along the fiber optic ferrule axis without being affected by the ferrule wall. During the centrifugal degassing process, the bottom of the fiber optic ferrule abuts against the anti-overflow pad, thus sealing the bottom of the fiber optic ferrule and preventing adhesive from overflowing due to centrifugal force. As the centrifuge speed increases, the centrifugal force on the fiber optic ferrule increases, increasing the pressure of the fiber optic ferrule against the anti-overflow pad, thereby improving the sealing effect of the anti-overflow pad on the bottom of the fiber optic ferrule. In this way, the degassing device completely removes air bubbles from the adhesive within the fiber optic ferrule without causing adhesive loss, improving the degassing effect and ensuring product quality.

[0045] Please see Figures 1 to 2 In some embodiments of this application, the fiber optic ferrule injection and defoaming device 100 proposed in this application includes a centrifuge host 10, a rotor support 20, and a tray assembly 30. The rotor support 20 is provided with a connector 21 and is mounted on the output end of the centrifuge host 10. The tray assembly 30 is rotatably mounted on the rotor support 20 via the connector 21.

[0046] The tray assembly 30 includes a ferrule support 31 and an anti-overflow pad 33. The ferrule support 31 has several limiting holes 32, which limit the radial direction of the fiber optic ferrule. The anti-overflow pad 33 is fitted against the bottom of the fiber optic ferrule within the limiting holes 32. When the centrifuge unit 10 operates, it drives the rotor support 20 to rotate, and the anti-overflow pad 33 forms a seal with the bottom of the fiber optic ferrule. The rotation axis of the tray assembly 30 relative to the rotor support 20 is perpendicular to the rotation center axis of the rotor support 20. The center of gravity of the tray assembly 30 is lower than the height of the tray assembly 30 relative to the rotation axis of the rotor support 20. The axis of the limiting holes 32 is parallel to the perpendicular line passing through the center of gravity of the tray assembly 30 relative to the rotation axis of the rotor support 20.

[0047] Initially, the fiber optic ferrule is placed in the limiting hole 32 of the ferrule holder 31, which restricts the radial movement freedom of the fiber optic ferrule. The fiber optic ferrule abuts against the anti-overflow pad 33, which restricts the axial movement freedom of the fiber optic ferrule. During centrifugation, under the combined action of centrifugal force and gravity, the fiber optic ferrule tends to move towards the anti-overflow pad 33, thereby increasing the pressure between the fiber optic ferrule and the anti-overflow pad 33. Since the center of gravity of the tray assembly 30 is lower than the height of the tray assembly 30 relative to the rotation axis of the rotor holder 20, initially, due to gravity, the limiting hole 32 is in a vertical state, and the fiber optic ferrule in the limiting hole 32 abuts against the anti-overflow pad 33 by gravity. During centrifugation, the fiber optic ferrule in the limiting hole 32 abuts against the anti-overflow pad 33 by the combined force of gravity and centrifugal force. Therefore, the pressure between the fiber optic ferrule and the anti-overflow pad 33 increases, and increases with the increase of centrifugal force.

[0048] When the centrifuge host 10 is running, it drives the rotor support 20 to rotate. Under the action of centrifugal force, the tray assembly 30 rotates relative to the rotor support 20, eventually making the axis of the limiting hole 32 parallel to the direction of the resultant force of the centrifugal force and gravity on the tray assembly 30. This makes the axis of the fiber optic ferrule parallel to the direction of the resultant force of the centrifugal force and gravity on the tray assembly 30, thereby allowing the air bubbles in the glue in the fiber optic ferrule to be discharged along the axis of the fiber optic ferrule without being affected by the wall of the fiber optic ferrule.

[0049] During the centrifugal degassing process, the bottom of the fiber optic ferrule abuts against the anti-overflow pad 33, thereby forming a seal on the bottom of the fiber optic ferrule through the anti-overflow pad 33, preventing the glue inside the fiber optic ferrule from overflowing from the bottom of the fiber optic ferrule due to centrifugal force. As the operating speed of the centrifuge host 10 increases, the centrifugal force on the fiber optic ferrule increases, and the pressure of the fiber optic ferrule against the anti-overflow pad 33 increases, thereby improving the sealing effect of the anti-overflow pad 33 on the bottom of the fiber optic ferrule.

[0050] In this way, the bubble removal device completely removes air bubbles from the adhesive in the fiber optic socket without causing adhesive loss, thus improving the bubble removal effect and ensuring product quality.

[0051] During centrifugation, the fiber optic ferrule is subjected to centrifugal force, and the adhesive inside the ferrule also moves relative to it, thus compressing air bubbles within the adhesive. Since the density of the adhesive is greater than that of the air bubbles, the adhesive within the ferrule moves in the direction of the centrifugal force, while the air bubbles move away from it. This process removes air bubbles and fills the gaps in the adhesive within the ferrule. During this process, adhesive adhering to the walls of the fiber optic ferrule converges into the ferrule itself due to centrifugal force, thus reducing the requirements for the adhesive application effect on the fiber optic ferrule and simplifying the operation.

[0052] During centrifugation, the adhesive inside the fiber optic ferrule moves towards the bottom of the ferrule due to centrifugal force, pushing the air between the adhesive and the anti-overflow pad 33 towards the bottom of the ferrule. The bottom of the ferrule is sealed by the anti-overflow pad 33, and as the centrifugal force increases, the sealing effect of the anti-overflow pad 33 on the bottom of the ferrule strengthens, preventing the adhesive and the air between the adhesive and the anti-overflow pad 33 from leaking out. Therefore, the adhesive moving towards the bottom compresses the air between the adhesive and the anti-overflow pad 33, increasing the air pressure between them. This ensures that the adhesive does not leak from the bottom of the fiber optic ferrule during centrifugation. After the centrifugation process ends, the centrifuge unit 10 gradually stops operating. The centrifugal force on the fiber optic ferrule and the adhesive inside it gradually decreases until it disappears. During this process, because the air pressure between the adhesive and the anti-overflow pad 33 reaches a certain strength, as the centrifugal force on the fiber optic ferrule and the adhesive inside it gradually decreases, the fiber optic ferrule tends to move away from the anti-overflow pad 33 due to the air pressure between the adhesive and the anti-overflow pad 33. When the centrifugal force decreases to an insufficient level to balance the air pressure between the adhesive and the anti-overflow pad 33, the fiber optic ferrule will leave the anti-overflow pad 33 due to the air pressure, thereby breaking the seal of the anti-overflow pad 33 on the bottom of the fiber optic ferrule. This causes the air between the adhesive and the anti-overflow pad 33 to overflow from the bottom of the fiber optic ferrule until the air pressure between the adhesive and the anti-overflow pad 33 equals the atmospheric pressure. Due to the decrease in centrifugal force, the adhesive inside the fiber optic ferrule will not overflow with the air due to its tension. Thus, even if the seal between the fiber optic ferrule and the anti-overflow pad 33 is broken by compressed air, no adhesive overflow will occur.

[0053] The shape of the limiting hole 32 varies depending on the shape of the optical fiber ferrule to be processed; it can be a cylindrical hole, a rectangular hole, a triangular hole, etc.

[0054] In some exemplary embodiments of this application, the connector 21 is a limiting frame with a hollow center. The connector 21 can rotate at the rotor support 20, and the rotation direction of the connector 21 is the same as the rotation direction of the tray assembly 30. The shape of the hollow center of the connector 21 is adapted to the outline shape of the tray assembly 30. Protrusions are provided on both sides or around the tray assembly 30. After the tray assembly 30 is placed in the hollow position of the connector 21, the side wall of the hollow position of the connector 21 limits the side wall of the tray assembly 30. The protrusions on the tray assembly 30 abut against the side of the connector 21 facing the insertion direction of the tray assembly 30 to limit the vertical direction of the tray assembly 30.

[0055] Thus, after the tray assembly 30 is installed into the rotor bracket 20, the tray assembly 30 is limited by the connector 21, making the installation structure of the tray assembly 30 at the rotor bracket 20 more stable and reliable.

[0056] The pallet assembly 30 may also be provided with pick-up and drop protrusions on both sides to facilitate the operator to pick up and drop the pallet assembly 30.

[0057] Please see Figures 2 to 3 In some embodiments of this application, the anti-overflow pad 33 is provided with a plurality of anti-overflow grooves 34, the position and number of the anti-overflow grooves 34 are adapted to the position and number of the limiting holes 32, and the shape of the anti-overflow grooves 34 is adapted to the bottom of the optical fiber ferrule.

[0058] After the fiber optic ferrule is placed into the limiting hole 32 of the ferrule holder 31, the fiber optic ferrule abuts against the anti-overflow pad 33, and the bottom of the fiber optic ferrule is inserted into the anti-overflow groove 34. The anti-overflow groove 34 improves the sealing effect of the anti-overflow pad 33 on the bottom of the fiber optic ferrule.

[0059] Specifically, the anti-overflow pad 33 is made of silicone. Silicone pads are soft and have a smooth surface, allowing them to conform well to the bottom of the fiber optic ferrule, thus providing a good seal. When the centrifuge unit 10 is running, the pressure between the fiber optic ferrule and the anti-overflow pad 33 increases. The area on the surface of the anti-overflow pad 33 corresponding to the fiber optic ferrule is compressed and sinks, causing the bottom of the fiber optic ferrule to sink into the anti-overflow pad 33. Therefore, the sealing effect of the anti-overflow pad 33 on the fiber optic ferrule increases with increasing centrifugal force.

[0060] Please see Figure 3 In some embodiments of this application, the tray assembly 30 further includes a support plate 35, and an anti-overflow pad 33 is disposed between the insert bracket 31 and the support plate 35.

[0061] The anti-overflow pad 33 is supported by the support plate 35, ensuring that the side of the anti-overflow pad 33 facing away from the fiber optic ferrule remains flat, while the side of the anti-overflow pad 33 facing the fiber optic ferrule is compressed by the fiber optic ferrule and sinks down. This prevents the anti-overflow pad 33 from deforming as a whole due to the compression of the fiber optic ferrule or the centrifugal force, thereby ensuring the sealing effect of the anti-overflow pad 33 on the bottom of the fiber optic ferrule and improving the limiting effect of the anti-overflow pad 33 on the axial positioning of the fiber optic ferrule, so that the bottom of each fiber optic ferrule is stable near the same plane.

[0062] Furthermore, a clearance groove 36 is provided between the ferrule bracket 31 and the support plate 35, and an anti-overflow pad 33 is provided in the clearance groove 36.

[0063] The clearance groove 36 prevents direct contact and compression between the ferrule bracket 31 and the support plate 35 and the anti-overflow pad 33, thus avoiding tension and deformation of the anti-overflow pad 33 and affecting the formation of the airtight space. The clearance groove 36 between the ferrule bracket 31 and the support plate 35 prevents excessive glue overflow from the fiber optic ferrule from solidifying in the limiting hole 32 in case of accidental spillage, which would not only be difficult to clean but could also clog the limiting hole 32. Furthermore, the anti-overflow pad 33 can be cleaned directly through the clearance groove 36, eliminating the need for disassembly and simplifying the operation.

[0064] Please see Figures 2 to 3 In some embodiments of this application, the connector 21 is shaft-shaped and disposed on both sides of the tray assembly 30. The tray assembly 30 has slots 38 on both sides, which are adapted to the connector 21.

[0065] The connectors 21 on both sides of the tray assembly 30 restrict the degrees of freedom on both sides, preventing the tray assembly 30 from moving laterally. The engagement of the slots 38 with the connectors 21 allows the tray assembly 30 to rotate around the axis of the connectors 21. This ensures that the tray assembly 30 can rotate smoothly and reliably at the rotor support 20.

[0066] Specifically, the pallet assembly 30 is equipped with snap-fit ​​members 37 at both ends, and a slot 38 is disposed on the snap-fit ​​member 37. One end of the slot 38 extends toward the edge of the snap-fit ​​member 37 and communicates with the outside of the snap-fit ​​member 37. The slot 38 faces the bottom of the pallet assembly 30.

[0067] When loading fiber optic ferrules, first remove the tray assembly 30 from the rotor bracket 20, then place the glued fiber optic ferrule into the limiting hole 32 of the ferrule bracket 31, and finally place the tray assembly 30 back into the rotor bracket 20. To remove or place the tray assembly 30, simply pull or push it along the slot 38 to remove or place it from the rotor bracket 20. This simple and convenient operation not only facilitates maintenance but also reduces labor intensity and improves work efficiency.

[0068] Furthermore, a guide slope 39 is provided on the side wall of the end of the card slot 38 that is externally connected to the card connector 37.

[0069] When the tray assembly 30 is placed back into the rotor support 20, it is guided by the guide ramp 39, which makes the tray assembly 30 easier to put into the rotor support 20, further reducing the difficulty of operation, making the maintenance of the device more convenient, and further improving the work efficiency.

[0070] Please see Figures 1 to 2 In some embodiments of this application, the number of tray assemblies 30 is four, and the tray assemblies 30 are respectively mounted on the four sides of the rotor support 20 in the same manner.

[0071] Installing the four tray assemblies 30 on the four sides of the rotor support 20 can not only increase the number of fiber optic ferrules that can be de-bubbled at the same time and improve work efficiency, but also make the rotor support 20 more uniformly stressed during centrifugation, thereby improving the reliability and service life of the device.

[0072] Furthermore, the rotor support 20 has a centrally symmetrical structure, and a locking hole 22 is provided in the center of the rotor support 20. The rotor support 20 is installed at the output end of the centrifuge host 10 through the locking hole 22.

[0073] The centrally symmetrical rotor support 20 ensures more even stress distribution during centrifugation, improving the reliability and service life of the device. The rotor support 20 is installed at the output end of the centrifuge unit 10 via the locking hole 22. To remove the rotor support 20 from the centrifuge unit 10, simply pull it; the operation is simple and convenient, and the simple structure facilitates maintenance. When installing the rotor support 20 at the output end of the centrifuge unit 10, the output end of the centrifuge unit 10 is inserted into the locking hole 22 of the rotor support 20. The rotor support 20 is securely installed at the centrifuge unit 10 through gravity and the interaction between the locking hole 22 and the output end of the centrifuge unit 10.

[0074] The output end of the centrifuge host 10 can also be inserted through the card hole 22 and protrude above the rotor support 20. The rotor support 20 is further limited by tightening the lock nut into the output end of the centrifuge host 10, thereby improving the reliability of the rotor support 20 installed at the centrifuge host 10.

[0075] Please see Figure 4 It should be noted that, for ease of understanding, the rotation axis of the tray assembly 30 relative to the rotor support 20 is perpendicular to the rotation center axis of the rotor support 20. Let point A be the point at the connection between the tray assembly 30 and the rotor support 20, and point B be the point on the rotation axis. The line AB containing points A and B is the rotation axis of the tray assembly 30 relative to the rotor support 20. Let L1 be the vertical normal passing through the center of the rotor support 20, and line L1 is the rotation center axis of the rotor support 20. Lines AB and L1 are skew lines and perpendicular to each other.

[0076] To facilitate understanding, the axis of the limiting hole 32 is parallel to the perpendicular line to the axis of rotation of the pallet assembly 30 relative to the rotor support 20, passing through the center of gravity of the pallet assembly 30. Let point C be the location of the center of gravity of the pallet assembly 30. Draw a perpendicular line to line AB through point C, and define this perpendicular line as L2. Define the axis of the limiting hole 32 as Ln. Then, line L2 is perpendicular to line AB, line L2 passes through point C, and line Ln is parallel to line L2.
