Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic array processing technology, and more specifically, to a FA fiber optic array processing device. Background Technology
[0002] A fiber optic array typically consists of a substrate, optical fibers, a cover plate, and adhesive. The substrate is usually a rectangular plate, and the material is often chosen for its low coefficient of thermal expansion, such as silicon or glass, to ensure stress-free operation, high reliability, and no fiber displacement at high temperatures. The substrate has precisely etched V-grooves for positioning the optical fibers.
[0003] Existing processing equipment presents challenges in creating V-grooves on substrates, typically using diamond cutting tools to cut these grooves. First, a suitable tool, such as a 60° or 90° V-groove cutter, is selected based on the required angle and size of the V-groove for grooving and chamfering. This method is cost-effective, but the diamond cutting tool wears easily during the cutting process, requiring frequent resharpening. Furthermore, worn tools can alter the shape of the V-groove, making it difficult to meet high-precision requirements. This is especially true when fabricating multi-channel V-grooves, where accumulated equipment errors can reduce accuracy and yield. Therefore, we propose a FA fiber array processing device. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a FA fiber array processing device to solve the technical problems of severe wear, difficulty in ensuring accuracy, and high defect rate when using diamond cutting tools to perform 90-degree V-grooving.
[0005] To solve the above technical problems, this utility model provides the following technical solution: A FA fiber array processing device, including an arc-shaped component, a base, a clamping component, and an extension mechanism. A screw is rotatably installed inside the base. A knob is provided at one end of the base and is connected to the screw. A side plate is fixed to the upper front end of the base. A shaft is fixed in the middle of the arc-shaped component. A linkage component is provided in the shaft. Two clamping components are provided, and each clamping component has an end connector fixed to its outer end. The end connector has a slot. A connecting block is provided between the two clamping components, and a plug is fixed to both the upper and lower ends of the connecting block. The outer end of the plug is inserted into the socket on the end face of the clamping component. The extension mechanism is installed on the rear side of the connecting block.
[0006] In use, pressing the pressing blocks on both sides simultaneously moves the toothed pressing blocks, causing them to press against the toothed openings and slide the separation rod outwards. The separation rod then lifts the end connector connected to the arc-shaped part, causing the two clamping parts to separate outwards. The array substrate is then placed between the two clamping parts. Releasing the pressing blocks allows the arc-shaped part to return to its original position, thus securing the array substrate in place. This structural design enables convenient clamping and assembly. The elastic return of the rear arc-shaped part maintains the clamping force, ensuring the positioning stability of the array substrate and reducing the difficulty of manual loading and unloading. After assembly, manually rotating the knob rotates the screw, which in turn drives the rotating drum to move. During the drum's movement, the linkage arm is pulled. The bottom of the cylinder is tilted so that it deflects. The upper end of the linkage arm is fixed to the cylinder. Through the above operation, the linkage arm drives the arc-shaped part to deflect. The two ends of the cylinder slide down in the groove at the top of the side plate. When the cylinder is moved to the last end, the arc-shaped part drives the array substrate to complete a 45-degree deflection. The inner arc-shaped part consolidates the strength of the arc-shaped part itself. A pad is added at the angle between the arc-shaped part and the inner arc-shaped part to further improve the overall resilience and steel structure strength. At this time, the array substrate is tilted at a 45-degree angle. The milling cutter is inserted vertically to open a 90-degree V-groove on the surface of the array substrate, reducing the grooving error rate. The vertical insertion of the milling cutter ensures safety and further reduces the impact of wear on the grooving accuracy, ensuring the processing quality.
[0007] Preferably, a groove is provided on the upper inner side of the side plate, and the two ends of the arc-shaped component's cylinder are slidably installed in the corresponding grooves.
[0008] Preferably, the linkage consists of a linkage arm and a rotating cylinder, with the rotating cylinder rotatably mounted on the lower end of the linkage arm, the upper end of the linkage arm sleeved and fixed on the shaft cylinder, and the screw thread passing through the middle of the rotating cylinder.
[0009] Preferably, an inner arc component is fixed to the inner side of the arc component, and a pad is fixed at the angle between the arc component and the inner arc component. Both the arc component and the inner arc component are made of spring steel.
[0010] Preferably, the extension mechanism consists of a separating rod, a pressing block, and a box body. The pressing block is slidably installed in the openings on both sides of the box body. The inner end of the pressing block is fixed with symmetrically distributed toothed pressing blocks. There are four separating rods in total, and the four separating rods are slidably inserted into the upper and lower end faces of the box body respectively.
[0011] Preferably, the outer end of the separating rod is fixed to the corresponding end connector, the lower end of the separating rod is provided with a toothed pressure port, and the inclined pressure surface on the toothed pressure block is adapted to the inclined surface of the toothed pressure port. A positioning block is fixed in the middle of the box body, and the positioning block is connected to the inner end of the separating rod.
[0012] Preferably, the two ends of the arc-shaped component are respectively inserted into the slots of the corresponding end connectors, and the insertion end of the arc-shaped component is provided with a limiting strip.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of an extension mechanism, presses the pressing blocks on both sides, and the pressing blocks synchronously drive the toothed pressing blocks to move. The toothed pressing blocks squeeze the toothed pressing holes, causing the separation rod to slide outward and unfold. The separation rod lifts the end connector connected to the end of the arc-shaped part. At this time, the two clamping parts separate and unfold outward. The array substrate is placed between the two clamping parts. The pressing blocks are released, and the array substrate is clamped and fixed by the plastic springback of the arc-shaped part. Through the above structural design, this device can perform convenient clamping and assembly. The elastic return of the rear arc-shaped part maintains the clamping force, ensuring the positioning stability of the array substrate and reducing the difficulty of manual loading and unloading.
[0015] 2. This utility model also incorporates an arc-shaped component. Manual rotation of the knob drives a screw to rotate, which in turn drives a rotating drum to move. During this movement, the bottom of the linkage arm is pulled, causing it to deflect. The upper end of the linkage arm is fixed to the shaft. Through this process, the linkage arm drives the arc-shaped component to deflect. The two ends of the shaft slide down within the groove at the top of the side plate. When the rotating drum reaches its final position, the arc-shaped component causes the array substrate to deflect at a 45-degree angle. The inner arc component reinforces the arc-shaped component's strength. A pad is added at the angle between the arc-shaped component and the inner arc component to further improve the overall resilience and steel structure strength. At this point, the array substrate is tilted at a 45-degree angle. A milling cutter is then inserted vertically to create a 90-degree V-groove on the surface of the array substrate, reducing the grooving error rate. The vertical insertion of the milling cutter ensures safety and further reduces the impact of wear on grooving accuracy, ensuring processing quality. Attached Figure Description

A shaft cylinder 101 is fixed in the middle of the arc-shaped component 1. A linkage component 2 is provided at the shaft cylinder 101. A sliding groove is opened at the upper inner side of the side plate 302. The two ends of the shaft cylinder 101 of the arc-shaped component 1 are slidably installed in the corresponding sliding grooves. The linkage component 2 consists of a linkage arm 201 and a rotating cylinder 202. The rotating cylinder 202 is rotatably mounted at the lower end of the linkage arm 201. The upper end of the linkage arm 201 is sleeved and fixed on the shaft cylinder 101. The screw 303 is threaded through the middle of the rotating cylinder 202. A screw is fixed to the inner side of the arc-shaped component 1. The inner arc component 102 and the included angle between the arc component 1 and the inner arc component 102 are fixed with a pad 103. Both the arc component 1 and the inner arc component 102 are made of spring steel. Pressing the pressing blocks 702 on both sides causes the pressing blocks 702 to move the toothed pressing blocks 704 in sync. The toothed pressing blocks 704 squeeze the toothed pressing holes 706, causing the separating rod 701 to slide outward and unfold. The separating rod 701 lifts the end connector 6 connected to the end of the arc component 1. At this time, the two clamping parts 5 separate and unfold outward. The array substrate 4 is placed between the two clamping parts 5. The pressing block 702 is released, and the plastic springback of the arc component 1 resets the array substrate 4, so that the clamping parts 5 clamp and fix the array substrate 4. Through the above structural design, the device can be conveniently clamped and assembled. The elastic return of the rear arc component 1 maintains the clamping force, ensuring the positioning stability of the array substrate 4 and reducing the difficulty of manual loading and unloading.
[0024] like Figures 2 to 6As shown, this utility model relates to a FA fiber array processing device, including an arc-shaped component 1, a base 3, a clamping component 5, and an extension mechanism 7. Two clamping components 5 are provided, and each clamping component 5 has a termination component 6 fixed to its outer end. The termination component 6 has a slot 601. A connecting block 501 is provided between the two clamping components 5, and insertion rods 502 are fixed to both the upper and lower ends of the connecting block 501. The outer ends of the insertion rods 502 are inserted into the insertion ports on the end faces of the clamping components 5. The extension mechanism 7 is installed on the rear side of the connecting block 501 and consists of a separating rod 701, a pressing block 702, and a housing 703. The box body 703 is constructed as follows: pressing blocks 702 are slidably installed in the openings on both sides of the box body 703; symmetrically distributed toothed pressing blocks 704 are fixed to the inner end of the pressing blocks 702; four separating rods 701 are provided, and the four separating rods 701 are slidably inserted into the upper and lower end faces of the box body 703 respectively; the outer ends of the separating rods 701 are fixed to the corresponding end connectors 6; the lower ends of the separating rods 701 have toothed pressing holes 706, and the inclined pressing surface of the toothed pressing blocks 704 is adapted to the inclined surface of the toothed pressing holes 706; a positioning block 705 is fixed in the middle of the interior of the box body 703, and the positioning block 705 is aligned with the separating rods 701. The inner end of the arc-shaped part 1 is inserted into the slots 601 of the corresponding end connectors 6. The insertion end of the arc-shaped part 1 is provided with a limiting strip. When the knob 301 is turned manually, the knob 301 drives the screw 303 to rotate. The screw 303 drives the rotating drum 202 to move. During the displacement of the rotating drum 202, the bottom of the linkage arm 201 is pulled and deflected. The upper end of the linkage arm 201 is sleeved and fixed on the shaft cylinder 101. Through the above operation, the linkage arm 201 drives the arc-shaped part 1 to deflect. The two ends of the shaft cylinder 101 slide and descend in the slot at the top of the side plate 302. When the rotating drum 202 moves... At the final end, the arc-shaped component 1 drives the array substrate 4 to complete a 45-degree deflection. The inner arc component 102 consolidates the strength of the arc-shaped component 1 itself. A pad 103 is added at the angle between the arc-shaped component 1 and the inner arc component 102 to further improve the overall resilience and steel structure strength. At this time, the array substrate 4 is tilted at a 45-degree angle. The milling cutter is inserted vertically to open a 90-degree V-groove on the surface of the array substrate 4, reducing the grooving error rate. The vertical insertion of the milling cutter ensures safety and further reduces the impact of wear on the grooving accuracy, ensuring the processing quality.
[0025] Working Principle: This embodiment provides a FA fiber array processing device. During use, pressing the pressing blocks 702 on both sides simultaneously moves the toothed pressing blocks 704. The toothed pressing blocks 704 press the toothed pressing holes 706, causing the separating rod 701 to slide outwards. The separating rod 701 lifts the end connector 6 connected to the end of the arc-shaped component 1. At this time, the two clamping components 5 separate outwards, and the array substrate 4 is placed between the two clamping components 5. Releasing the pressing blocks 702 allows the arc-shaped component 1 to return to its original position through plastic springback, thus clamping and fixing the array substrate 4. After assembly, manually rotating the knob 301 causes the screw 303 to rotate. The screw 303's thread drive causes the rotating drum 202 to move. During the displacement process, the bottom of the traction linkage arm 201 is deflected. The upper end of the linkage arm 201 is sleeved and fixed on the shaft cylinder 101. Through the above operation, the linkage arm 201 drives the arc-shaped part 1 to deflect. The two ends of the shaft cylinder 101 slide down in the top slot of the side plate 302. When the rotating cylinder 202 is displaced to the last end, the arc-shaped part 1 drives the array substrate 4 to complete a 45-degree deflection. The inner arc-shaped part 102 consolidates the strength of the arc-shaped part 1 itself. A pad 103 is added at the angle between the arc-shaped part 1 and the inner arc-shaped part 102 to further improve the overall resilience and steel structure strength. At this time, the array substrate 4 is tilted at a 45-degree angle. The milling cutter used for cutting is inserted vertically, and a 90-degree angle V-groove can be opened on the surface of the array substrate 4.
