Description

Technical Field

[0001] This invention relates to the field of optical fiber preform production and manufacturing technology, and in particular to an integrated automatic loading, unloading and transfer system and working method for optical fiber preforms. Background Technology

[0002] Optical fiber preforms are the core raw material for manufacturing quartz optical fibers. The internal structure of the optical fiber is formed within the preform, making preform fabrication the most crucial part of the optical fiber manufacturing process. There are various methods for fabricating optical fiber preforms, with vapor-phase oxidation being a commonly used process. In vapor-phase oxidation, high-purity halide vapors react with oxygen to form oxide particles. These oxide particles deposit on the surface of the glass or quartz body (or the inner wall of a tubular structure), and are then sintered to form a transparent glass rod.

[0003] Currently, optical fiber preforms used in optical fiber production in the optical communication industry generally weigh around 100 kilograms. The methods used for transporting and hanging these preforms basically require personnel to participate throughout the entire process. On the one hand, this still poses certain safety hazards to some extent, and on the other hand, the level of automation is relatively low, which does not meet the requirements for the transformation and upgrading of modern enterprises. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem of poor safety and great safety hazards in the transportation of optical fiber preforms in the prior art.

[0005] To address the aforementioned technical problems, this invention provides an integrated automatic loading, unloading, and transfer system and method for optical fiber preforms, comprising: a ground-floor optical fiber preform transport device, installed on the ground floor, used for transporting optical fibers; a freight elevator with two doors, A and B, both of which can be opened from opposite sides, used to transfer optical fibers from lower floors to higher floors; an optical fiber guide trough, installed inside the freight elevator, used to receive optical fibers from the ground-floor optical fiber transport device; an optical fiber tilting trolley, located at a higher floor, used to receive optical fibers from the optical fiber guide trough; and a preform hanging platform, located at a higher floor, where the optical fiber tilting trolley transports optical fibers to the hanging platform and tilts the optical fibers from horizontal to vertical, and the hanging platform suspends the optical fibers.

[0006] In one embodiment of the present invention, the structure of the first-floor light rod transport device and the light rod guide trough is the same, and both the first-floor light rod transport device and the light rod guide trough include a bottom support frame, a horizontal support plate, a servo motor, and guide rollers. The horizontal support plate is fixedly mounted on the bottom support frame, and the servo motor is mounted on the horizontal support plate. Several parallel guide rollers are respectively provided on the two opposite long sides of the horizontal support plate. The axial direction of the guide rollers is inclined at an angle to the vertical line. The guide rollers on the two opposite long sides of the horizontal support plate are arranged in a V-shape. The light rod is disposed between the guide rollers on the two opposite long sides of the horizontal support plate, and the light rod and the guide rollers are in a rolling connection.

[0007] In one embodiment of the present invention, both ends of the guide roller are connected to synchronous pulleys in the axial direction, and a synchronous belt is provided between the synchronous pulleys on adjacent guide rollers, and the synchronous pulleys on the guide rollers are driven by the synchronous belt.

[0008] In one embodiment of the present invention, the light rod tilting carriage includes a mobile trolley, a frame, a tilting power source, a base, a tilting frame, and guide wheels arranged in pairs opposite each other. The frame is fixedly mounted on the mobile trolley. One end of the tilting power source is hinged to the frame, and the telescopic rod of the tilting power source is hinged to the tilting frame. The end of the tilting frame is connected to the frame via a pivot. The base is fixedly mounted on the end of the tilting frame, and a signal switch is provided on the base. The signal switch is used to detect that the light rod has moved into position on the tilting frame. The guide wheels arranged in pairs opposite each other are arranged in a V-shape. The tilting frame is provided with a plurality of guide wheels. The light rod is in contact with the guide wheels, and the light rod and the guide wheels are in a rolling connection.

[0009] In one embodiment of the present invention, the flipping frame is provided with a plurality of safety clamps, which are used to fix the light bar on the flipping frame.

[0010] In one embodiment of the present invention, the safety clamp includes a guide rail, a clamping motor, a bidirectional threaded screw, a clamping rod one, and a clamping rod two. The clamping rod one and the clamping rod two are symmetrically arranged, and one end of each clamping rod one and the clamping rod two are slidably connected to the guide rail. The clamping motor is fixedly mounted on the tilting frame and is connected to the bidirectional threaded screw. The bidirectional threaded screw has a forward thread and a reverse thread with opposite helical directions. The clamping rod one is connected to the forward thread, and the clamping rod two is connected to the reverse thread. The clamping motor drives the bidirectional threaded screw to rotate to move the clamping rod one and the clamping rod two closer together or further apart.

[0011] In one embodiment of the present invention, the rod-hanging platform includes a linear module one, a linear module two, a rod-hanging frame, a rod-hanging block, and a support column. The linear module one is disposed on the support column, and the linear module two is connected to the linear module one. The linear module one and the linear module two constitute a dual-axis moving system. The rod-hanging frame is connected to the linear module two. The linear module one drives the rod-hanging frame to move in the vertical direction, and the linear module two drives the rod-hanging frame to move in the horizontal direction. The rod-hanging block is disposed on the lower end of the rod-hanging frame and is used to suspend the light rod.

[0012] In one embodiment of the present invention, the hanging rod block is provided with a U-shaped groove, the inner wall of the U-shaped groove is provided with a limiting step, the tail of the light rod is disposed in the U-shaped groove, and the protrusion of the tail of the light rod engages with the limiting step.

[0013] In one embodiment of the present invention, the power source for the tilting is a hydraulic cylinder.

[0014] In one embodiment of the present invention, a method for operating an integrated automatic loading, unloading, and transfer system for optical fiber preforms includes the following steps:

[0015] S1. After the wire drawing of the light rod is completed, the trolley with the tailpipe removed is pushed to the designated area, triggering the signal for the system to hang the rod.

[0016] S2. The first-floor light rod transport device is started. The servo motor drives the guide roller to rotate at a constant speed, moving the light rod placed on the guide roller to the light rod guide groove in the freight elevator. When it reaches the set limit, the limit signal is triggered.

[0017] S3. The light rod transport device on the first floor stops operating, the elevator door A closes automatically, the elevator automatically rises to the designated production floor, and then the elevator door B opens automatically, triggering the rod transport signal.

[0018] S4. The light bar transport device inside the freight elevator, namely the light bar guide trough, is started. The servo motor drives the guide trough rollers to rotate at a constant speed, moving the light bar placed on the guide trough rollers to the light bar tilting car.

[0019] S5. When the light bar is transported to the bottom support position of the light bar tilting vehicle, a signal is triggered;

[0020] S6. Safety clamp starts, driving the bidirectional threaded screw to rotate through the clamping motor. When the bidirectional threaded screw rotates, clamp rod one and clamp rod two move relative to each other on the guide rail, and clamp rod one and clamp rod two move synchronously to clamp the light bar.

[0021] S7. After the light bar clamping action is completed, the automatic tilting and tilting frame is raised to a vertical position by the tilting power source. The central control system controls the light bar tilting vehicle to automatically move to the line where the light bar needs to be hung and triggers the hanging signal.

[0022] S8. When linear module one is started, the hanging rod platform moves upward until it triggers the limit of the light rod tilting car, and then immediately stops moving up and down. When linear module two is started, the hanging rod platform moves forward until the U-shaped slot is in complete contact with the light rod tail shank boss, and then immediately stops moving forward and backward. When linear module one is started, the hanging rod platform moves upward 20mm and then automatically stops moving up and down. When linear module two is started, the hanging rod platform moves backward to the zero position and then automatically stops moving forward and backward.

[0023] S9. The central control system automatically controls the light bar tilting car to move to its original position, triggers the tilting signal, and the light bar tilting car automatically tilts to a horizontal position and is flush with the light bar guide groove in the freight elevator for standby. The system triggers the end signal for transporting the hanging bar, the freight elevator door B automatically closes, the freight elevator automatically descends to the first floor, and the freight elevator door A automatically opens to await the next bar transport action.

[0024] The technical solution of the present invention has the following advantages over the prior art:

[0025] The automatic loading, unloading and transfer system for optical fiber preforms described in this invention can automatically transport optical fiber preforms to a freight elevator via a first-floor optical fiber transport device. The freight elevator then automatically transports the optical fiber preforms to a designated processing floor. The optical fiber preforms are automatically received and transported via optical fiber preform guide channels within the freight elevator. After the optical fiber preforms arrive at the designated floor, they are received by an optical fiber preform tilting cart, which can also tilt the optical fiber preforms. The tilting cart tilts the optical fiber preforms so that they are vertical and are finally suspended on a preform hanging platform, thus realizing a fully automated process integrating preform transport, hanging, and unloading.
