Description

Technical Field

[0001] This utility model relates to the field of optical fiber preform manufacturing, and specifically to an optical fiber preform transfer device. Background Technology

[0002] With the rapid development of optical fiber communication, the scale of optical fiber usage and manufacturing has been continuously expanding. Optical fiber manufacturing technology has also been developing towards larger-sized optical fiber preforms, with some preforms exceeding 200 millimeters in diameter. On the optical fiber production line, optical fiber preforms need to be transferred between different processes, and the geometric requirements for the preforms (such as horizontal or vertical orientation) vary between these processes.

[0003] Currently, patent CN 210912501 U discloses an optical fiber preform transfer vehicle, which includes a vehicle body, a flipping platform, a clamping device for fixing the optical fiber preform, and a first driving device.

[0004] However, the aforementioned patent can only transfer one optical fiber preform, which affects the efficiency of the transfer. Furthermore, the installation and disassembly of the optical fiber preform are relatively troublesome, and one end is in rolling contact with the optical fiber preform, making it impossible to quickly position it. This also affects the stability after installation and the safety during the transfer process. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an optical fiber preform transfer device that can simultaneously transport and install multiple optical fiber preforms, and facilitates their subsequent removal through staggered positioning, thereby solving the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: an optical fiber preform transfer device, comprising multiple optical fiber preforms and multiple grooves arranged from top to bottom. Each groove has multiple clamping seats installed inside it. Each clamping seat consists of a bearing seat and a pressing seat. Each bearing seat has a groove for inserting the pressing seat into the groove. One end face of both the bearing seat and the groove has an arc-shaped groove. Adjacent arc-shaped grooves are combined to form clamping grooves that match the end face of the optical fiber preform. The optical fiber preforms are all placed inside the grooves, with both ends inserted into the clamping grooves and clamped and fixed by the pressing seat and the bearing seat. Except for the uppermost clamping seat, the remaining clamping seats are pressed by the upper grooves. The uppermost groove has a cover plate that presses the corresponding clamping seat, and a limiting mechanism for vertically positioning the groove is installed on one side of the cover plate.

[0007] As a preferred technical solution, the limiting mechanism includes multiple positioning rods and multiple cylinders. One side of the groove body protrudes to form an extension, and the extension is provided with multiple positioning grooves. The positioning rods are vertically arranged in the vertically opposite positioning grooves. One end of each positioning rod is equipped with a hinge, and the other end of each hinge is installed on the groove body. The cylinders are installed on the other end of the positioning rods, and the piston rods of the cylinders are fixedly connected to the cover plate. Multiple limiting holes are provided on the opening end face of the uppermost groove body. Limiting posts are installed on the inner side of the cover plate opposite to the limiting holes, and the limiting posts are inserted into the positioning holes.

[0008] As a preferred technical solution, longitudinal plates are installed in the openings at both ends of the tank. Except for the uppermost tank, the longitudinal plates of the remaining tanks are provided with guide grooves, one end of which extends into the extension. Except for the lowermost tank, guide blocks are installed on the bottom surface of the remaining tanks opposite the guide grooves. The guide blocks are slidably disposed in the guide grooves, and the cross-sections of the guide blocks and guide grooves are both trapezoidal.

[0009] As a preferred technical solution, a base plate is installed on the bottommost trough, and multiple casters with brakes are installed on the base plate.

[0010] As a preferred technical solution, both the bearing seat and the clamping seat on one side are provided with arc-shaped holes, and adjacent arc-shaped holes are combined to form a positioning channel that communicates with the clamping groove. One end of the optical fiber preform passes through the positioning channel.

[0011] As a preferred technical solution, both sides of the groove are provided with vertical sliding grooves, and both sides of the pressing seat protrude to form sliders, which are slidably disposed in the sliding grooves.

[0012] As a preferred technical solution, a pad is installed in the middle of the tank, and the middle of the optical fiber preform is placed on the pad. Both the pad and the clamp are made of rubber material.

[0013] The beneficial effects of this utility model are as follows: This utility model has a simple structure. After the clamping seat is opened, the optical fiber preform can be placed into the arc-shaped groove of the bearing seat. After the clamping seat is reinstalled, the corresponding clamping seat can be pressed by the groove and cover plate located above to complete the positioning of the optical fiber preform. Moreover, multiple grooves can be used to rotate multiple optical fiber preforms at one time, which increases the efficiency of rotation. Furthermore, the limiting mechanism can vertically position the stacked grooves to ensure stability during the rotation process. After the limiting mechanism is opened, the grooves can move along the guide groove, so that the grooves can be misaligned, thereby smoothly taking out and inserting the optical fiber preform.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention discloses an optical fiber preform transfer device, comprising multiple optical fiber preforms 17 and multiple grooves 1 arranged from top to bottom. Each groove 1 has multiple clamping seats installed inside, each clamping seat consisting of a bearing seat 12 and a pressing seat 13. Each bearing seat 12 has a groove for inserting the pressing seat 13 into the groove. The pressing seat 13 is inserted into the groove. Each end face of the bearing seat 12 and the groove has an arc-shaped groove 18. Adjacent arc-shaped grooves 18 are combined to form clamping grooves that match the end faces of the optical fiber preforms 17. The optical fiber preforms 17 are all disposed inside the grooves 1, and both ends of the optical fiber preforms 17 are inserted into the clamping grooves and clamped and fixed by the pressing seat 13 and the bearing seat 12. Except for the uppermost clamping seat, the remaining clamping seats are all clamped by the upper grooves 1. The uppermost groove 1 is provided with a cover plate 10 for clamping the corresponding clamping seats. A limiting mechanism for vertically positioning the groove 1 is installed on one side of the cover plate 10.

[0021] In this embodiment, the limiting mechanism includes multiple positioning rods 5 and multiple cylinders 6. One side of the groove 1 protrudes to form an extension 2, and multiple positioning grooves 3 are provided on the extension 2. The positioning rods 5 are vertically arranged in the vertically opposite positioning grooves 3. One end of each positioning rod 5 is equipped with a hinge 4, and the other end of each hinge 4 is installed on the groove 1. The cylinders 6 are installed on the other end of the positioning rods 5. The piston rods of the cylinders 6 are fixedly connected to the cover plate 10. Multiple limiting holes 15 are provided on the opening end face of the uppermost groove 1. Limiting posts are installed on the inner side of the cover plate 10 opposite to the limiting holes 15. The limiting posts are inserted into the positioning holes. One side of the base plate can be equipped with an air source, a power source, and a controller, which can provide electrical power to the cylinder and also control the cylinder.

[0022] In this embodiment, longitudinal plates 7 are installed in the openings at both ends of the trough 1. Except for the uppermost trough 1, the longitudinal plates 7 of the remaining trough 1 are provided with guide grooves 11. One end of each guide groove 11 extends into the extension portion 2. Except for the lowermost trough 1, guide blocks 21 are installed on the bottom surface of the remaining trough 1 opposite to the guide grooves 11. The guide blocks 21 are slidably disposed in the guide grooves 11. The cross-sections of the guide blocks 21 and the guide grooves 11 are both trapezoidal. The trough can be positioned by the guide grooves and guide blocks, so that the trough can only move along the guide grooves.

[0023] In this embodiment, a base plate 8 is installed on the bottommost trough 1, and multiple casters 9 with brakes are installed on the base plate 8. The casters can push the device, enabling the device to move with the optical fiber preform.

[0024] In this embodiment, both the bearing seat 12 and the clamping seat 13 on one side are provided with arc-shaped holes 20. Adjacent arc-shaped holes 20 are combined to form a positioning channel that communicates with the clamping groove. One end of the optical fiber preform 17 passes through the positioning channel.

[0025] In this embodiment, both sides of the groove are provided with vertical sliding grooves 19, and both sides of the pressing seat 13 are provided with protruding sliders 14. The sliders 14 are slidably disposed in the sliding grooves 19. The pressing seat can be positioned by the sliders and sliding grooves to ensure the stability after installation.

[0026] In this embodiment, a pad 16 is installed in the middle of the groove 1, and the optical fiber preform 17 is placed on the pad 16 in the middle. The pad 16 and the clamping seat are both made of rubber material, so that the pad and the clamping seat are made of flexible material to contact the optical fiber preform, thereby reducing the probability of damage to the optical fiber preform during transportation.

[0027] During use, the trough can move along the guide groove, allowing the troughs to be misaligned, thus ensuring that the opening of each trough is in the open state. After the clamping seat is removed, the optical fiber preform can be placed into the arc-shaped groove of the carrier seat. After the clamping seat is placed in again, both ends of the optical fiber preform can be positioned. After the optical fiber preform is placed, the trough is moved back to its original position along the guide groove. The trough can press the clamping seat below downward, so that the clamping seat can press and position the optical fiber preform to ensure stability during the transportation process. The positioning rod can be lifted upwards around the hinge, allowing it to be inserted into the positioning groove. The movement of the positioning rod drives the cylinder and the cover plate until the cover plate is positioned parallel to the top of the groove. After the piston rod of the cylinder retracts, the cover plate presses onto the topmost groove and also presses the topmost clamping seat. The limiting post on the cover plate can be inserted into the limiting hole. The positioning rod and the positioning rod can be positioned by insertion. The positioning rod can vertically position the groove, preventing longitudinal movement of the groove during transportation and ensuring its stability. After being transported to the designated location, the cylinder can be activated again, causing the piston rod to extend. After the cover plate is lifted, the limiting post can be pulled out of the limiting hole and rotate outward around the hinge. After the positioning rod is no longer obstructed, the tank can move along the guide groove, allowing the tanks to be misaligned, thus opening the opening above the tank and facilitating the removal of the optical fiber preform from the tank.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
