Description

Technical Field

[0001] This utility model belongs to the field of fiber optic patch cord production technology, specifically relating to a fiber optic patch cord feeding device. Background Technology

[0002] In the production process of fiber optic patch cords, after the fiber optic cable is cut to a preset length according to the production process requirements and coiled into a fiber optic cable reel, the assembly process of components such as ceramic ferrules, plastic connectors, metal rings, heat shrink tubing, and cable ends needs to be completed. Specifically, the above components are inserted into the beginning and end of the fiber optic cable in a specific order. This process is one of the key steps to ensure the subsequent connection performance and structural stability of the fiber optic patch cord.

[0003] In existing technologies, the threading operation for the aforementioned components largely relies on manual labor: operators must first manually fix the fiber optic reel, then lead out both ends of the fiber optic cable one by one from the reel and temporarily fix them, and then hold each component and align it with the end of the fiber optic cable to thread it in sequence. However, manual threading has significant drawbacks: on the one hand, manual operation is inefficient and difficult to adapt to the pace requirements of large-scale production, and the skill level and proficiency of operators vary, which can easily lead to problems such as component insertion position deviation and disordered sequence, affecting the consistency of fiber optic patch cord product quality; on the other hand, long-term manual operation requires a large investment of manpower, and long hours of manual work can easily lead to fatigue, further increasing the risk of product defect rate.

[0004] To address the drawbacks of manual fiber optic cable threading, the industry urgently needs to automate the aforementioned component threading process. One prerequisite for automated threading is the stable clamping and fixing of the ends of the cut and coiled fiber optic cable reel, followed by precise transport of the clamped reel to the designated threading station. However, current technology, due to the characteristics of fiber optic cables such as weak resistance to external damage, thin diameter, and poor tensile strength, lacks a suitable conveying and unloading device to accurately transport the fiber optic cable reel to the fitting station and fix both ends of the fiber optic cable to positions that mate with the fitting clamps. This technological gap directly hinders the realization of automated fiber optic patch cord component threading, becoming a key bottleneck restricting the improvement of fiber optic patch cord production efficiency and quality. Utility Model Content

[0008] Preferably, a limiting groove is provided between the first connecting part and the mounting plate, and a connecting plate fixedly connected to the mounting plate is provided in the limiting groove. The connecting plate is fixedly connected to the outside of any chain plate in the chain to realize the fixed connection between the chain and the mounting plate, so that the mounting plate can be driven to move when the chain rotates.

[0009] Preferably, there are two connecting plates: one is located in the limiting groove and is fixedly connected to the outer side of the lower chain plate in the chain, and the other is located directly above the limiting groove and is fixedly connected to the outer side of the upper chain plate in the chain.

[0010] Preferably, there are two second connecting parts, symmetrically arranged on both sides of the first connecting part, with a gap between the two second connecting parts. A second rotating member is provided in the gap, which is perpendicular to the mounting plate. The diameter of the second rotating member is greater than the thickness of the second connecting part, and the second rotating member protrudes downward from the second connecting part. At the end of each of the two second connecting parts away from the mounting plate, there are also two first rotating members arranged parallel to the mounting plate. The diameter of the first rotating member matches the diameter of the limiting track, and the first rotating member is located in the limiting track.

[0011] Preferably, the second rotating member is tangentially disposed to the top of the limiting track to avoid friction between the first connecting member and the limiting track.

[0012] Preferably, the top plate and the bottom plate have a rectangular structure in the middle and semicircular structures at both ends, and the two rotating shafts are respectively coaxial with the semicircles at both ends of the top plate and the bottom plate.

[0016] The fiber optic patch cord feeding device provided in this embodiment of the utility model has at least one of the following technical effects:

[0017] The fiber optic patch cord feeding device of this utility model can achieve continuous and stable transmission of fiber optic cable reels through the meshing of gear disc and chain, and the sliding cooperation of limiting track and mounting mechanism, so that subsequent processes such as sleeve can be carried out without interruption, which meets the rhythm requirements of large-scale production.

[0018] The fiber optic patch cord feeding device of this invention can effectively limit the position of the fiber optic cable under the action of the limiting baffles on both sides of the mounting plate, thus ensuring the overall stability of the fiber optic cable reel during the conveying process.

[0021] The fiber optic patch cord feeding device of this utility model, with the structure of the connecting plate and the outer side of the upper and lower chain plates fixedly connected, and with the cooperation of two limiting rails and two connecting parts, can drive the mounting plate to move more stably when the chain rotates, ensuring the smoothness and accuracy of the transmission process, and thus ensuring that the fiber optic cable reel can be accurately delivered to the preset component threading station.

[0039] In one embodiment of this utility model, such as Figure 1 As shown, a fiber optic patch cord feeding device is provided, including a transmission mechanism 10 and a mounting mechanism 20. The transmission mechanism 10 is the power transmission and guiding structure of this feeding device, used to drive the mounting mechanism 20 to move cyclically along a preset trajectory. The transmission mechanism 10 is a ring-shaped side-mounted conveying device. There are multiple mounting mechanisms 20, which are slidably disposed on the outer surface of the transmission mechanism 10. Fiber optic reels are hung on the mounting mechanisms 20, and the ends of the fiber optic reels are fixed to the mounting mechanisms 20. The mounting mechanisms 20 rotate along the transmission mechanism 10 under the drive of the transmission mechanism 10, thereby moving the fiber optic reels to the subsequent assembly parts station. The transmission mechanism 10 and the mounting mechanism 20 cooperate with each other to achieve continuous, stable, and accurate feeding of the fiber optic reels, providing a guarantee for the subsequent automated threading process of fiber optic patch cord components.

[0040] like Figure 1-3 As shown, the transmission mechanism 10 includes a base plate 11, a top plate 12, a support rod 13, a rotating shaft 14, a gear disk 15, a chain 16, a limiting track 17, and a drive device 18.

[0041] The base plate 11 is a plate-shaped structure with a rectangular middle and semi-circular ends. The base plate 11 is made of a high-strength metal material. The top plate 12 has the same structure as the base plate 11 and is symmetrically arranged. The top plate 12 is mounted parallel to the base plate 11 directly above it. The top plate 12 and the base plate 11 together form the upper and lower support frames of the transmission mechanism 10.

[0042] Multiple support rods 13 are evenly distributed between the bottom plate 11 and the top plate 12. The lower end of the support rod 13 is fixedly connected to the top of the bottom plate 11, and the upper end is fixedly connected to the bottom of the top plate 12. The support rod 13 fixes the bottom plate 11 and the top plate 12, thereby enhancing the overall structural stability of the transmission mechanism 10. At the same time, an arc-shaped groove 131 is provided on the outer wall of the support rod 13. The groove 131 fits against the inner wall of the limiting track 17, thereby enhancing the connection strength between the support rod 13 and the limiting track 17.

[0043] There are two rotating shafts 14, which are respectively set at the two ends of the top plate 12 and the bottom plate 11. The rotating shafts 14 are connected to the top plate 12 and the bottom plate 11 through bearings, so that the rotating shafts 14 can rotate relative to the top plate 12 and the bottom plate 11. One end of one of the rotating shafts 14 passes through the bottom plate 11 and extends downward. The extended end is fixedly connected to the output end of the drive device 18. The drive device 18 is a servo motor to drive the rotating shaft 14 to rotate.

[0044] There are four gear disks 15, which are fixedly installed at the upper and lower ends of the two rotating shafts 14 respectively. The gear disks 15 located at the upper ends of the two rotating shafts 14 are on the same horizontal plane, and the gear disks 15 located at the lower ends of the two rotating shafts 14 are on the same horizontal plane. All gear disks 15 are located between the bottom plate 11 and the top plate 12.

[0045] The chain 16 has two parts. One part is connected to the gear disk 15 located at the upper end of the two rotating shafts 14, and the other part is connected to the gear disk 15 located at the lower end of the two rotating shafts 14. That is, the gear disk 15 at the upper end of the two rotating shafts 14 is connected by a chain 16, and the gear disk 15 at the lower end of the two rotating shafts 14 is connected by a chain 16, forming a symmetrical double chain transmission structure. When the rotating shaft 14 connected to the drive device 18 rotates, the chain 16 can be driven to rotate through the gear disk 15.

[0046] There are two limiting rails 17. Each limiting rail 17 is U-shaped with a rectangular groove that opens upwards in the middle. The limiting rail 17 is rectangular in the middle and semi-circular at both ends and is horizontally arranged between the two chains 16. The limiting rail 17 is fixedly connected to the support rod 13 and is sleeved around the two rotating shafts 14. The limiting rail 17 extends along the length of the chain 16 and maintains a preset distance from the chain 16. The limiting rail 17 provides a guide rail for the sliding of the mounting mechanism 20.

[0047] The drive device 18 is a servo motor with a gearbox, which is fixed to the top of the top plate 12 by a bracket. The output end of the drive device 18 is fixedly connected to the bottom end of one of the rotating shafts 14 through a coupling. The servo motor can be precisely speed-adjusted and can adjust the moving speed of the mounting mechanism 20 according to the operation rhythm of the subsequent component threading station.

[0048] like Figure 4-5 As shown, the mounting mechanism 20 includes a first connecting member 21, a first rotating member 22, a second rotating member 23, a connecting plate 24, a second connecting member 25, a mounting plate 26, a limiting baffle 27, a hook 28, and a fixing claw 29. The second connecting member 25 has the same structure as the first connecting member 21. The first connecting member 21 is slidably disposed in the limiting track 17 adjacent to the top plate 12, and the second connecting member 25 is slidably disposed in another limiting track 17.

[0049] The first connector 21 includes a first connecting portion 211 and a second connecting portion 212. The first connecting portion 211 is fixedly connected to one side of the mounting plate 26. There are two second connecting portions 212, symmetrically arranged on the side of the first connecting portion 211 away from the mounting plate 26 and extending away from the mounting plate 26. A gap is formed between the two second connecting portions 212. A second rotating member 23 perpendicular to the mounting plate 26 is provided in the gap. The second rotating member 23 is rotatably connected to the first connecting portion 211. Specifically, the second rotating member 23 includes a fixed shaft perpendicular to and fixedly connected to the first connecting portion 211 and a bearing provided on the fixed shaft. The bearing is located in the gap, and the diameter of the bearing in the second rotating member 23 is larger than that of the second connecting portion 212. The thickness of the second rotating part 23 and the bearing in the second rotating part 23 protruding downward from the bottom surface of the second connecting part 25, and the second rotating part 23 being tangentially disposed to the top of the limiting track 17; the two second connecting parts 212 are also provided with a first rotating part 22 parallel to the height direction of the mounting plate 26 at the ends away from the mounting plate 26, the first rotating part 22 being rotatably connected to the second connecting part 212, specifically, the first rotating part 22 includes a fixed shaft perpendicular to and fixedly connected to the second connecting part 212 and a bearing disposed on the fixed shaft, the bearing being located in the groove of the limiting track 17, the diameter of the bearing of the first rotating part 22 matching the width of the groove of the limiting track 17, and the first rotating part 22 being inserted into the limiting track 17 and being able to slide along the track.

[0050] A limiting groove 213 is provided at the middle position of the side of the first connecting part 211 adjacent to the mounting plate 26. A connecting plate 24 is provided in the limiting groove 213. The connecting plate 24 is located in the limiting groove 213 and is fixedly connected to the outer side of any lower chain plate of the chain 16. The other end of the connecting plate 24 is fixedly connected to the mounting plate 26. Another connecting plate 24 is provided directly above the limiting groove 213. This connecting plate 24 is fixedly connected to the outer side of the upper chain plate of the chain 16, and the other end is fixedly connected to the mounting plate 26. Through the fixing structure of the double connecting plates 24, and the fact that one of the connecting plates 24 is set in the limiting groove 213, the stability of the connection between the chain 16 and the mounting plate 26 is ensured. At the same time, the cooperation of the first rotating part 22, the second rotating part 23 and the limiting track 17 prevents the mounting plate 26 from shaking when the chain 16 rotates.

[0051] The mounting plate 26 has a rectangular plate structure. Two parallel hooks 28 are fixed to the lower part of the mounting plate 26 on the side away from the first connector 21. The distance between the two hooks 28 is adapted to the diameter of the fiber optic coil. The lower end of each hook 28 has an upwardly bent mounting portion 281 with a rubber anti-slip pad and anti-slip texture to increase friction with the fiber optic coil and prevent displacement due to vibration during transmission. Above each hook 28 is a fixing claw 29 fixed to the mounting plate 26. The fixing claw 29 is a clamping structure to clamp the fiber optic cable end. Limiting baffles 27 are also vertically fixed to both sides of the mounting plate 26. The width of the limiting baffles 27 is wider than the diameter of the fiber optic coil, and the length of the limiting baffles 27 is the same as the length of the hooks 28 protruding from the mounting plate. The limiting baffles 27 can limit the left and right movement of the fiber optic cable hanging on the hooks 28.

[0052] The working principle of this utility model is as follows: In use, the cut and coiled optical fiber reel is first hung on the two hooks 28 of the mounting mechanism 20. The mounting part 281 of the hook 28 and the anti-slip pad are used to achieve stable suspension of the optical fiber reel. Then, the ends of the optical fiber reel are clamped in the fixing claws 29 on the top of the mounting plate 26 to complete the loading and fixing of the optical fiber reel. The two parallel hooks 28 with a gap can prevent the reel from shifting or rotating during the transport process when the claws pull the optical fiber, which would cause the optical fiber to be torn. This ensures the safety and reliability of the operation. Then the drive device 18 is started, which drives the rotating shaft 14 connected to it to rotate. The rotating shaft 14 drives the chain 16 to rotate through the gear discs 15 at the upper and lower ends. Since the individual chain plates in the chain 16 are fixedly connected to the mounting plate 26 through the connecting plate 24, and the mounting plate 26 is slidably engaged with the limiting track 17 through the first connecting piece 21 and the second connecting piece 25, the chain 16 will drive the mounting mechanism 20 to move smoothly along the limiting track 17 when it rotates.

[0053] During the movement of the mounting mechanism 20, the first rotating part 22 in the first connecting part 21 slides along the inner side of the limiting track 17, and the second rotating part 23 rolls tangentially with the top of the limiting track 17, which greatly reduces the frictional resistance between the mounting mechanism 20 and the limiting track 17, ensuring a smooth and uninterrupted movement. The limiting baffles 27 on both sides of the mounting plate 26 can prevent the fiber optic coil from swaying left and right, and avoid the fiber optic cable from getting tangled or shifting. When the mounting mechanism 20 moves the fiber optic reel to the preset component threading station, the drive device 18 pauses. At this time, the wire ends at both ends of the fiber optic reel are fixed by the clamping claws 29 and are exactly within the action range of the fitting claws. The fitting claws can directly grab the wire ends to perform threading operations for components such as ceramic ferrules and heat shrink tubing. After the operation at this station is completed, the drive device 18 restarts, driving the mounting mechanism 20 to continue moving and transporting the completed fiber optic reel to the next station. At the same time, the mounting mechanism 20 with unprocessed fiber optic reels enters the threading station in sequence to achieve continuous automated feeding.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
