Description

Technical Field

[0001] This utility model relates to the packaging field of optical fiber production, specifically a device for wrapping a thin film around the surface of an optical fiber disc. Background Technology

[0002] After a reel of optical fiber is packaged, the fiber itself will have static electricity, and dust particles in the environment will be attracted to the surface of the fiber, affecting the quality of the fiber. In addition, if the fiber is not used for a long time, the ultraviolet rays in the environment will cause the fiber coating to re-cured, and the chemical fiber will be over-cured and yellowed, affecting the quality of the fiber.

[0003] Wrapping a layer of black plastic film around the surface of an optical fiber can isolate dust particles and prevent the fiber coating from re-curing. Currently, the black plastic film is usually wrapped manually. On the one hand, it is difficult to control the tightness of the wrapping film, resulting in uneven wrapping and gaps on both sides of the reel. On the other hand, manual operation is cumbersome, involving placing the wrapping film, using an air gun to blow dust off the surface of the optical fiber, rotating the fiber reel to wrap the plastic film, holding the wrapping film with one hand to maintain a certain tension, and using a knife to cut the wrapping film with the other hand. It is labor-intensive and poses safety hazards. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1-3The figure shows a device for winding a thin film onto the surface of an optical fiber tray. It includes a frame 1, a tray shaft 2 for mounting the optical fiber tray, a film holder 3 that can rotate around the tray shaft 2, a cutter 8, and a first drive mechanism for driving the cutter 8. In this embodiment, the frame 1 includes a lower support frame and an upper main frame. The upper main frame includes a working chamber 1-1 and a unit chamber 1-2, separated from the working chamber 1-1 by a partition 4. The working chamber 1-1 has an openable door 5 on one side. The frame 1 is equipped with a dust removal device 6, which can be a suction mechanism or a blowing mechanism. The suction port of the dust removal device 6 extends into the working chamber 1-1. The door 5 is a double-leaf type and is made of transparent material. Dust on the fiber optic disc is removed by the dust removal device 6. In this embodiment, the membrane frame 3 is located in the working chamber 1-1, and the disc shaft 2 extends partially into the working chamber 1-1. The membrane frame 3 is provided with a membrane tube, specifically a fixed shaft 7 for the membrane tube to be fitted on the membrane frame 3. The membrane tube is fitted and fixed on the fixed shaft 7. In this embodiment, the disc shaft 2 is connected to a second drive mechanism for driving the disc shaft 2 to rotate and a third drive mechanism for driving the membrane frame 3 to rotate. The membrane frame 3 is driven to rotate around the disc shaft 2 to wind the film around the fiber optic disc; or the disc shaft 2 is driven to rotate to drive the fiber optic disc to wind the film around the fiber optic disc; or the disc shaft 2 and the membrane frame 3 are both driven to rotate in opposite directions to wind the film around the fiber optic disc. After the film is wound, the film is cut by driving the cutter 8 to move. In this embodiment, the fiber optic disc is mounted on the disc shaft 2, and the membrane tube is mounted on the membrane frame 3. The disc shaft 2 or the membrane frame 3, or both, can be driven to rotate simultaneously. When both rotate simultaneously, their directions should be opposite to improve efficiency. This is typically used when multiple layers need to be coated. Control parameters can be set as needed to achieve this. Both the control and implementation methods are mature technologies available on the market and will not be elaborated upon here. After the disc shaft 2 and / or the membrane frame 3 complete the coating process, the cutter 8 is driven to cut the film. After cutting, the cutter 8 retracts to its initial position, completing all coating operations. During the coating process, workers can observe the internal workings through the transparent door 5. When the membrane frame 3 rotates but the disc shaft 2 does not, the membrane frame 3 is driven to rotate around the disc shaft 2 to wrap the film around the fiber optic disc. When the disc shaft 2 rotates but the membrane frame 3 does not, the disc shaft 2 is driven to rotate, causing the fiber optic disc to rotate and wrap the film around it. At the beginning of the coating process, the end of the film needs to be manually placed on the fiber optic tray. Generally, the film has a certain degree of adhesion and will stick to the surface of the fiber optic tray. Of course, a film pressing device can also be set up as needed to assist in the process. This can be added as needed later. This is a common technique in this field and will not be described in detail here.

[0024] In this embodiment, the first driving mechanism includes a cylinder 9, a swing arm 10, and a blade holder 11. A cutter 8 is mounted on the blade holder 11, which is fixed to the swing arm 10. The swing arm 10 is movably connected to the frame 1. The cylinder 9 is fixed to the frame 1. The cylinder 9 drives the swing arm 10 to rotate, thereby controlling the rotation of the cutter 8 on the blade holder 11 to cut the film. In this embodiment, an arc-shaped groove 4-1 for the blade holder 11 to move is provided on the partition 4.

[0025] This embodiment also includes a telescopic rod 12 supporting the film. The telescopic rod 12 can extend and retract within the rotation trajectory range of the film frame 3. When the film needs to be cut, the telescopic rod 12 extends, and when the cutter 8 presses against the film, the telescopic rod 12 provides support for the film. In this embodiment, if the film frame 3 does not rotate, the telescopic rod 12 can be designed as a fixed rod, or it can be designed to be in a normally extended state. The telescopic function of the telescopic rod 12 is mainly to make way for the rotation of the film frame 3. In this embodiment, the telescopic rod is a cylinder. The cylinder body is installed in the unit chamber, and the piston of the cylinder extends into the working chamber when it moves.

[0026] This embodiment also includes a second drive mechanism for driving the disc shaft 2 to rotate. The second drive mechanism includes a first motor 13, which is driven by the disc shaft 2. It also includes a third drive mechanism for driving the film frame 3 to rotate. The third drive mechanism includes a second motor 14, the output end of which is connected to a reducer 15. The film frame 3 is driven by the reducer 15. The reducer 15 has a hollow shaft 16, which drives the film frame 3. The disc shaft 2 passes through the hollow shaft 16; or a drive shaft driven by the disc shaft 2 passes through the hollow shaft 16, allowing relative rotation between the disc shaft 2 and the hollow shaft 16. The reducer 15 is fixed to the partition plate 4, the second motor 14 is fixed to the reducer 15, and a mounting plate 17 is also fixed to the reducer 15. The first motor 13 is fixed to the mounting plate 17. A driven wheel 18 is connected to the end of the disc shaft 2, and a driving wheel 19 is connected to the output shaft of the first motor 13. The driven wheel 18 and the driving wheel 19 are driven by each other. In this embodiment, the installation space of the reducer 15 is cleverly utilized, and the first motor 13 is installed on top of it through the mounting plate 17, so that the unit chamber 1-2 can be made smaller, thereby reducing the space occupied by the entire equipment and making the equipment more compact.

[0027] This invention controls the number of product rotations based on the number of layers of stretch film set in the controller's human-machine interface. During product rotation, the dust removal device 6 eliminates dust and static electricity from the product and stretch film. After the tray rotation angle detection component detects the set number of layers of stretch film, the automatic film cutting component cuts the stretch film, and the product is removed, ending the entire process. The air blowing component of the dust removal device 6 in this patent has a special gas nozzle designed according to the characteristics of the tray. This not only effectively removes dust but also ensures that the stretch film adheres smoothly and tightly to the product. Therefore, a film pressing device is not required to achieve the adhesion of the film end to the fiber optic tray surface, utilizing the friction between the film and the fiber optic tray to cover the fiber optic tray. The first motor 13 and the second motor 14 adopt a servo system, which can precisely control the product's rotation angle. The tray rotation angle detection component collects angle information in real time and sends it to the control system to adjust the servo system output in real time to ensure that the rotation angle is consistent with the set parameters.
