Description

Technical Field

[0001] This invention relates to the field of optical fiber communication equipment technology, specifically to an intelligent temperature-controlled heat shrink tubing heating device and method for splicing 12-core optical fibers. Background Technology

[0002] As the core transmission medium for dense communication, the splicing quality of 12-core optical fiber directly determines the stability of the link transmission. Heat shrink tubing curing is a crucial process to ensure the mechanical strength and optical performance of the splice. Existing heating devices and methods have many technical limitations: Firstly, the heating components are cumbersome to disassemble and assemble. Traditional devices use bolt fixing or one-piece molding design. When maintaining the heating plate or cleaning the heat shrink tubing, multiple parts need to be disassembled, which is time-consuming and laborious, and can easily damage the heating elements. Secondly, the heating uniformity is poor. Most of them adopt an integral heating structure. The dense arrangement of 12 optical fibers leads to uneven heating of each core heat shrink tube, resulting in local overheating and carbonization or insufficient shrinkage. The splicing loss dispersion exceeds ±0.05dB. Third, it lacks intelligence and a precise sensing and triggering mechanism, requiring manual start and stop of heating, which is prone to misoperation (such as starting heating without inserting the optical fiber or failing to cut off the power in time after heating is completed). In addition, the temperature control relies on fixed parameters and cannot be adapted to different specifications of heat shrink tubing. Fourth, there is an imbalance between portability and protection. Mains power supply devices are limited by the site, and generators need to be carried in addition to the field. Portable devices often have simplified protective structures, which are prone to failure due to collisions and dust. Fifth, the lack of adaptability design and fixed heating channel size make it incompatible with 12-core fiber heat shrink tubing of different outer diameters. Furthermore, the messy cable arrangement can easily cause micro-bending damage to the fiber. Therefore, an intelligent temperature-controlled heat shrink tubing heating device and method for splicing 12-core optical fibers is proposed. Summary of the Invention

After the temperature reaches the set value, it enters the constant temperature stage and is maintained for the set time, during which the heat shrink tubing gradually shrinks and solidifies. The shrinkage status is monitored visually through the transparent window of the heating plate cover 21. If the heat shrink tubing in a certain channel does not shrink sufficiently, the main board automatically extends the constant temperature time of that channel and fine-tunes the temperature. Once the set time is reached or shrinkage is complete, the main board automatically cuts off the heating power and enters the cooling stage. The top cover is kept closed for natural cooling for 20 seconds to prevent the heat shrink tubing from cracking due to sudden cooling. After cooling is complete, the touch screen displays "Heating Complete" and the audible and visual alarm unit issues a prompt signal. The latch and top cover are opened, and the 12-core optical fiber is taken out to complete the connection. If the heating plate needs to be cleaned, the heating plate fixing seat can be separated directly by magnetic attraction. After cleaning, it can be reassembled magnetically. Fold the handle 18 for storage.
