Description

Technical Field

[0001] This utility model relates to the field of dispensing devices, and in particular to a FA fiber array dispensing device. Background Technology

[0002] A fiber optic array (FA) is an optical element formed by fixing multiple optical fibers onto a specially designed substrate according to a specific arrangement, spacing, and precision requirements. It typically consists of a substrate, optical fibers, and a cover plate. In the production process of an FA, the ribbon fiber is first precisely placed into a V-groove on the substrate. Then, an adhesive dispensing device dispenses adhesive into the V-groove, using the adhesive's stickiness to fix the fiber in place. Existing dispensing devices primarily involve a robotic arm gripping the FA substrate, placing it in a corresponding fixture, and then the dispensing head dispensing adhesive onto the FA substrate. After dispensing, the robotic arm grips the dispensed FA substrate again and transports it to the next processing step. However, this dispensing method suffers from low tooling efficiency because it processes only one FA substrate at a time. The alternating dispensing and loading / unloading processes result in a long dispensing time for a single FA substrate, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an FA fiber array dispensing device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an FA fiber array dispensing device, comprising a worktable, a control robot, dispensing heads, a bracket, an electric guide rail, a positioning frame, a belt conveyor, and positioning holes; the control robot is mounted on the worktable, and the output end of the control robot is provided with several dispensing heads; the bracket is mounted on the worktable; two electric guide rails are mounted on the bracket;

[0005] The positioning frame is slidably mounted on the electric guide rail, and the two positioning frames are located on both sides of the control robot.

[0006] The belt conveyor is set on the workbench and is located below the positioning frame. The belt conveyor is used to transport the FA optical fiber substrate after dispensing.

[0007] The positioning holes are arranged in two or more rows on the positioning frame. Each row consists of several positioning holes, and each row of positioning holes corresponds one-to-one with several dispensing heads. The positioning holes are used to provide positioning for the FA fiber array.

[0008] The positioning frame is equipped with a clamping assembly, which is used to clamp and fix the FA fiber array.

[0009] Preferably, two position sensors are installed on the workbench, and the two position sensors are located at the front and rear ends of the top of the bracket, respectively.

[0010] Preferably, the position sensor is a laser displacement sensor.

[0011] Preferably, a baffle is installed at each of the front and rear ends of the inner side of the bracket. When the positioning frame moves to the end of the electric guide rail, the baffle is in contact with the bottom surface of the positioning frame. At this time, the baffle completely covers the bottom inner side of all the positioning holes.

[0012] Preferably, the width of the conveyor belt on the belt conveyor is greater than the width of the positioning frame.

[0013] Preferably, the clamping assembly includes two sliding grooves formed in the positioning hole, a clamping plate slidably installed in the sliding groove, a lifting cylinder installed on the side surface of the positioning frame, and a lifting frame set above the positioning frame and connected to the piston rod of the lifting cylinder. The two sliding grooves in the positioning hole are arranged opposite to each other. The clamping plate is connected to the inner end face of the sliding groove by a spring. The lifting frame is offset from the positioning hole. A pressing rod is installed at the bottom of the lifting frame. The pressing rod is a cone shape that is larger at the top and smaller at the bottom. After the pressing rod moves through the top surface of the positioning frame, it contacts the clamping plate. When the pressing rod moves downward, it presses the clamping plate to move outward along the sliding groove, so as to realize the clamping plate moving outward to clamp and fix the FA fiber array.

[0014] Preferably, a gasket is attached to the outer end face of the clamp.

[0015] Preferably, the gasket is one of a silicone gasket, a polyurethane gasket, or a rubber gasket.

[0016] The beneficial effects of this utility model are:

[0017] This invention features multiple rows of positioning holes on the positioning frame, facilitating the simultaneous placement of multiple FA substrates. Multiple dispensing heads are used to dispense adhesive onto these substrates simultaneously. Furthermore, the presence of two sets of electric guide rails and positioning frames allows the robotic arm to place another set of FA substrates into an idle positioning frame while one set is being dispensed. This alternating dispensing of FA substrates between the two sets results in higher dispensing efficiency for a single FA substrate. After dispensing is complete, the clamping components release, allowing the dispensed FA substrate to fall onto the conveyor belt without requiring the robotic arm to remove it. This reduces the dispensing time for a single FA substrate, better meeting the needs of large-scale production. Attached Figure Description

Detailed Implementation

[0023] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, this utility model provides a FA fiber array dispensing device, including a worktable 1, a control robot 3, dispensing heads 4, a bracket 5, an electric guide rail 6, a positioning frame 7, a belt conveyor 8, and positioning holes 9; the conveying control robot 3 is installed on the worktable 1, and the output end of the control robot 3 is provided with 4 dispensing heads 4, which facilitates dispensing adhesive to 4 FA substrates at the same time; the bracket 5 is installed on the worktable 1; two electric guide rails 6 are installed on the bracket 5;

[0025] The positioning frame 7 is slidably mounted on the electric guide rail 6. The two positioning frames 7 are located on both sides of the control robot 3 to facilitate the alternating transport of the FA substrate by the two positioning frames 7.

[0026] The belt conveyor 8 is installed on the workbench 1 and is located below the positioning frame 7. The belt conveyor 8 is used to transport the FA fiber substrate after dispensing. In order to ensure that the FA substrate in the positioning frame 7 can fall accurately onto the belt conveyor 8, the width of the conveyor belt on the belt conveyor 8 is greater than the width of the positioning frame 7.

[0027] The positioning holes 9 are arranged in 5 rows on the positioning frame 7. Each row consists of 4 positioning holes 9. The positioning holes 9 in each row correspond one-to-one with the 4 dispensing heads 4. The positioning holes 9 are used to provide positioning for the FA fiber array.

[0028] The positioning frame 7 is equipped with a clamping assembly, which is used to clamp and fix the FA fiber array.

[0029] In this embodiment, in order to accurately detect the position of the positioning frame 7 and facilitate the control console to accurately control the external feeding machinery, two position sensors 2 are installed on the workbench 1. The two position sensors 2 are located at the front and rear ends of the top of the bracket 5, respectively, and the position sensors 2 are laser displacement sensors.

[0030] In this embodiment, a baffle 17 is installed at each of the front and rear ends of the inner side of the bracket 5. When the positioning frame 7 moves to the end of the electric guide rail 6, the baffle 17 is in contact with the bottom surface of the positioning frame 7. At this time, the baffle 17 completely covers the bottom of the inner side of all the positioning holes 9 to prevent the FA substrate from falling directly downward after entering the inner side of the positioning hole 9. In this embodiment, the thickness of the baffle 17 is 0.2cm to 0.5cm, and the distance from the bottom surface of the baffle 17 to the top of the belt conveyor 8 is 0.5cm to 1cm to reduce the distance between the FA substrate and the belt conveyor 8, so that the FA substrate can fall stably onto the belt conveyor 8.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, the clamping assembly includes two slide grooves 10 respectively opened at the front and rear ends of the inner side of the positioning hole 9, a clamping plate 11 slidably installed in the slide groove 10, a lifting cylinder 13 installed on the side surface of the positioning frame 7, and a lifting frame 14 disposed above the positioning frame 7 and connected to the piston rod of the lifting cylinder 13.

[0032] The clamping plate 11 is connected to the inner end face of the slide groove 10 by the spring 16. The outer end face of the clamping plate 11 is attached with a gasket 12 to reduce the damage to the FA substrate when the clamping plate 11 clamps the FA substrate. The lifting frame 14 is set along the groove edge of the top of the positioning frame 7, so that the lifting frame 14 is misaligned with the positioning hole 9.

[0033] A pressing rod 15 is installed at the bottom of the lifting frame 14. The pressing rod 15 is a cone shape that is larger at the top and smaller at the bottom. After the pressing rod 15 moves through the top surface of the positioning frame 7, it contacts the clamping plate 11. The pressing rod 15 is used to press the clamping plate 11 to move outward along the slide groove 10 when it moves downward, so that the clamping plate 11 moves outward to clamp and fix the FA fiber array.

[0034] Lifting cylinder 13 is a pneumatic cylinder;

[0035] In the above, gasket 12 is a silicone gasket, but gasket 12 can also be a polyurethane gasket or a rubber gasket;

[0036] In use, the electrical equipment in this device is connected to the external control equipment, and the lifting cylinder 13 is connected to the external pneumatic equipment. A robotic arm for conveying FA substrates is provided outside the device. The robotic arm conveys the FA substrate with the ribbon optical fiber placed in the V groove to the positioning hole 9 of the rear positioning frame 7. The FA substrate enters the positioning hole 9 and contacts the baffle 17. Multiple FA substrates are placed into multiple positioning holes 9 in sequence.

[0037] Then, the lifting rod 13 is controlled to drive the lifting frame 14 and the extrusion rod 15 to move downward. The extrusion rod 15 moves downward and the extrusion clamp 11 moves outward along the slide 10 to clamp and fix the FA substrate. The electric guide rail 6 is controlled to drive the positioning frame 7 and the FA substrate to move. During the movement of the positioning frame 7, the position sensor 2 accurately detects the position of the positioning frame 7 until the positioning frame 7 drives the FA substrate to move below the dispensing head 4. At this time, the control and adjustment robot arm 3 drives the dispensing head 4 to dispense the strip fiber in the FA substrate. During the dispensing process, the robot arm puts another set of FA substrates into the positioning hole 9 of the front positioning frame 7.

[0038] After dispensing is completed, the lifting cylinder 13 drives the lifting frame 14 and the extrusion rod 15 to move upward. The clamping plate 11 is retracted into the slide groove 10 by the elastic force of the spring 16. The FA substrate falls downward onto the belt conveyor 8 under the action of gravity. The belt conveyor 8 transports the dispensed FA substrate. The electric guide rail 6 controls the positioning frame 7 at the rear end to move backward and reset. The electric guide rail 6 at the front end controls the positioning frame 7 at the front end and the FA substrate to move backward to the dispensing head 4 for dispensing, so as to realize the alternating transport of FA substrates and thus perform dispensing work more continuously.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
