Description

Adaptive FA Coupling Fixture Technical Field

[0001] This utility model relates to the field of clamps, and in particular to an adaptive FA coupling clamp. Background Technology

[0002] Fiber optic arrays (FAs) are optical devices formed by arranging and fixing a bundle of optical fibers or fiber ribbons at specified intervals on a V-groove substrate. The substrate is usually made of silicon or glass. In the manufacturing and assembly process of FAs, the precise fixing of the substrate is crucial to ensuring fiber alignment and coupling efficiency. In applications, FA substrates require slotting, fixing, and fiber installation. Current technologies often employ rigid clamping or manual screw locking methods for fixing FA substrates, which often lack adaptability and are difficult to adapt to substrates of different sizes. Frequent adjustments to the clamp structure are necessary when changing products, resulting in low efficiency, inconvenience, and low precision. Furthermore, general clamps are typically fixed to a single platform, making it difficult to adapt to the flexible needs of various scenarios.

[0003] Therefore, a FA coupling fixture with adaptive adjustment capability, simple operation and strong compatibility is provided to improve assembly efficiency and accuracy. Summary of the Invention

[0004] In view of the above, this utility model provides an adaptive FA coupling fixture, which has the characteristics of adaptive adjustment capability, simple operation, strong compatibility and high flexibility.

[0005] The present invention specifically adopts the following technical solution: an adaptive FA coupling fixture, comprising a set of clamping units or two sets of identical and symmetrically arranged clamping units. Each set of clamping units includes a base, a pressure rod handle, a pressure block, a limiting block, and a spring. The middle part of the pressure rod handle is hinged to the base, and the two ends of the pressure rod handle are respectively connected to the pressure block and the spring. When one end of the spring is pressed, the pressure rod handle drives the pressure block to move up and down. The limiting block is located on the base and below one end of the pressure block. The product is placed on the base and attached to the side of the limiting block.

[0006] As a further improved technical solution, the pressure block includes a rotating part, a pressing part, a connecting part, and a supporting part. The rotating part is located at the top of the connecting part, and a rotating groove is provided on the pressure rod handle. The rotating part of the pressure block is movably located in the rotating groove of the pressure rod handle.

[0007] As a further improved technical solution, the pressing part is located at one end of the connecting part, forming an "L" shaped structure with the connecting part, and the supporting part is located at the other end of the connecting part, with the supporting part forming a protruding arc surface on the lower surface of the connecting part.

[0008] As a further improved technical solution, the limiting block is provided with a strip-shaped screw hole, and the adjusting screw passes through the strip-shaped screw hole to set the limiting block on the base.

[0009] As a further improved technical solution, a lever leg is connected below the lever handle, and a hole is opened on the base corresponding to the position of the lever leg. The lever leg is set in the hole through a hinge shaft.

[0010] As a further improved technical solution, the two ends of the spring are respectively connected to the base and the pressure rod handle.

[0011] As a further improved technical solution, the base is provided with a base adjustment screw hole, which is strip-shaped.

[0012] As a further improved technical solution, the base adjustment screw hole is provided with one or more, and the number is the same in both sets of clamping units and they are symmetrical to each other.

[0013] The adaptive FA coupling fixture of this invention achieves efficient and stable clamping of the FA substrate through a lever-spring linkage structure and adjustable limit design, as detailed below.

[0014] 1. Adaptive clamping, compatible with multiple substrate sizes. The rotating part of the clamping block rotates freely within the groove of the clamping rod handle. Combined with the "L"-shaped pressing part and the spherical support part, the angle can adaptively adjust according to the substrate height, ensuring uniform clamping surface against substrates of different thicknesses. A sliding limit block with a strip-shaped screw hole adapts to substrates of different widths, eliminating the need for repeated adjustments when changing to products of the same width, significantly improving efficiency.

[0015] 2. Convenient operation and stable clamping force: Pressing one end of the handle synchronously controls the opening and closing of the clamping block; the spring automatically resets after releasing the handle, enabling quick clamping and avoiding torque deviations caused by manual tightening. During descent, the clamping block rotates around the limit block as a fulcrum, automatically correcting its position and eliminating clamping tilt problems caused by substrate placement deviations. Through the synergistic action of the limit block and the clamping block, the substrate can be securely fixed, ensuring the accuracy and reliability of fiber optic installation.

[0016] 3. Flexible adaptation to multiple scenarios: A single clamping unit can be used to fix the substrate, or two sets of clamping units can be used together. Each set of clamping units can be slidably set, flexibly adjusting the position of the clamping units, or fixed to different platforms (such as optical platforms, automated equipment), expanding application scenarios. Symmetrical clamping units can be disassembled and maintained independently, reducing usage costs. When two sets are used together, it is also easy to adjust the spacing between the two sets of clamping units.

[0017] In summary, this fixture solves the problems of poor compatibility and cumbersome operation of existing technologies through mechanical adaptive design, significantly improving FA assembly efficiency and product yield, and is especially suitable for small-batch, multi-variety optical communication device production scenarios.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0025] Referring to Figures 1-2, this embodiment provides an adaptive FA coupling fixture, including one set of clamping units 100 or two sets of identical and symmetrically arranged clamping units 100. Each set of clamping units includes a base 1, a pressure handle 2, a pressure block 3, a limiting block 4, and a spring 5. The central axes of the pressure handle 2, the pressure block 3, the limiting block 4, and the spring 5 coincide on the same straight line of the base 1. The middle part of the pressure handle 2 is hinged to the base 1, and the two ends of the pressure handle 2 are respectively connected to the pressure block 3 and the spring 5. When one end of the spring 5 is pressed, the pressure handle 2 drives the pressure block 3 to move up and down. The limiting block 4 is located on the base 1 and below one end of the pressure block 3. The product is placed on the base 1 and attached to the side of the limiting block 4. The product is a substrate 200 for FA (fiber optic array). The substrate is fixed for fiber optic installation. Depending on the size of the substrate 200, the clamping unit can be used individually or in groups. When two sets of clamping units 100 are used together, the substrate 200 is placed in the middle of the two clamping units 100. The limiting blocks 4 of the two clamping units 100 clamp the substrate 200 onto the base 1. The pressure bar handle 2 drives the pressure block 3 to press the substrate 200 from above, thereby stabilizing the substrate 200.

[0026] Referring to Figure 3, specifically, the pressure block 3 includes a rotating part 31, a pressing part 32, a connecting part 33, and a supporting part 34. The rotating part 31 is located at the top of the connecting part 33. A rotating groove 21 is provided on the handle 2 of the pressure rod, and the rotating part 31 of the pressure block 3 is movably located within the rotating groove 21 of the handle 2 of the pressure rod. The opening of the rotating groove 21 is smaller than the size of the rotating part 31 of the pressure block to prevent the pressure block 3 from sliding out of the rotating groove 21. The rotating part 31 can rotate freely within the rotating groove 21, allowing the pressure block 3 to adaptively press onto substrates 200 of different sizes. The connecting part 33 is a straight long rod. The pressing part 32 is located at one end of the connecting part 33, forming an "L" shape with the connecting part 33, and the connection point has a smooth, rounded transition. The supporting part 34 is located at the other end of the connecting part 33, and the supporting part 34 forms a protruding arc surface on the lower surface of the connecting part 33. The pressure lever handle 2 lowers the pressure block 3. The pressing part 32 of the pressure block 3 contacts the top surface of the substrate 200. The support part 34 of the pressure block 3 uses the limiting block 4 as a fulcrum. As the pressure block 3 is lowered, the rotating part 31 of the pressure block 3 rotates adaptively on the pressure lever handle 2 until it self-corrects to the position of clamping the product. The rotating part 31 of the pressure block 3 is provided with blocking members 311 at both ends to prevent the rotating part 31 of the pressure block 3 from sliding out laterally from the rotating groove 21 of the pressure lever handle 2. In this embodiment, the blocking members can be selected as large-head screws, which are directly set at both ends of the rotating part 31.

[0027] The limiting block 4 has a slotted screw hole. An adjusting screw passes through the slotted screw hole to set the limiting block on the base 1. The slotted screw hole provides space for movement. Adjusting the adjusting screw allows the limiting block 4 to slide horizontally on the base 1, thereby limiting substrates 200 of different widths. An adjusting hole 22 is provided on the pressure rod handle 2 at the position corresponding to the adjusting screw below, for easy adjustment.

[0028] A lever leg 23 is connected below the lever handle 2. A hole is provided on the base 1 corresponding to the position of the lever leg 23. The lever leg 23 is set in the hole through a hinge shaft 24. In this embodiment, a stepped screw is preferably used as the hinge shaft 24. The stepped screw is passed through the screw hole on the side of the hole. The threaded section of the head of the stepped screw is screwed into the pre-embedded threaded hole of the base to ensure that the smooth section of the stepped screw is perpendicular to the surface of the base. A hole is opened at the bottom of the lever leg 23. A bushing can be inserted into the hole and the smooth section is fitted in. Thus, the smooth section of the stepped screw and the lever leg are rotated through a precision clearance fit.

[0029] The two ends of spring 5 are fixedly connected to base 1 and pressure handle 2, respectively. This design utilizes the principle of spring and lever. When loading, pressing one end of spring 5 on pressure handle 2 causes pressure block 3 to open. Adjusting the position of limit block 4 allows the substrate 200 to be placed in. Releasing the hand causes pressure block 3 to automatically clamp substrate 200, and limit block 4 to lock against both sides of the substrate. For substrates 200 of the same width but different height, limit block 4 does not need to be adjusted. Refer to Figures 4 and 5 for schematic diagrams of the fixing states of substrates of two different sizes.

[0030] In addition, the base 1 has a base adjustment screw hole 11, which is strip-shaped. The adaptive FA coupling fixture of this application can be fixed to a multi-scene platform or device through the base 1. The base 1 is fixed to the required platform or device by the base adjustment screw 11 cooperating with the base adjustment screw hole. At the same time, adjusting the base adjustment screw can slide the base 1, thereby adjusting the fixed position of the individual clamping unit 100 or the relative gap between the two clamping units 100, which further increases the flexibility and applicability of the adaptive FA coupling fixture of this application.

[0031] Furthermore, the above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of this specification should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
