Manufacturing method of optical cable

Abstract: The invention discloses a manufacturing method of an optical cable. The manufacturing method comprises the following steps of 1) processing a framework of which an outer side wall is provided with a plurality of mounting grooves, and embedding a reinforcer into a hollow part of the framework; 2) placing optical fiber units in the corresponding mounting grooves; 3) covering a cover plate at an opening end of the mounting groove; 4) wrapping outer sides of the framework and the cover plate with a water-blocking wrapping tape; 5) forming a sheath with a positioning structure on an outer side of the water-blocking wrapping tape through a plastic extruding machine, n groups of positioning structures being arranged on an outer side wall of the sheath, the positioning structures being matched with the mounting grooves in a one-to-one correspondence mode, each group of positioning structures comprising two positioning grooves, the two positioning grooves of each positioning structure corresponding to two sides of the corresponding mounting groove respectively, at least N-1 groups of positioning structures comprising recognition grooves, and the number of the recognition grooves of each positioning structure being different, and 6) cooling and drying the sheath, and rolling to obtain the optical cable. The method is advantaged in that an optical cable produced by the method can quicklydetermine the specific positions of different mounting grooves.

Aluminum tape connection apparatus for optical cable manufacturing

Abstract: The invention discloses an aluminum tape connection device for optical cable manufacturing. The device comprises an aluminum tape coil installation rack, a laser distance measuring sensor, a quick uncoiling device, an aluminum tape welding device, two supporting rotating wheels, a photoelectric sensor, and a controller; the aluminum tape coil installation rack comprises a first rotating shaft anda second rotating shaft; the laser distance measuring sensor is used for measuring a distance between the detection head of the laser distance measuring sensor and an aluminum tape coil mounted on thefirst rotating shaft; the quick uncoiling device is used for quickly uncoiling the aluminum tape coil mounted on the first rotating shaft, so that the aluminum tape of the aluminum tape coil can be completely uncoiled; the aluminum tape welding device is used for welding the starting end of the aluminum tape of an aluminum tape coil mounted on the second rotating shaft to the tail end of the completely uncoiled aluminum tape; the two supporting rotating wheels are arranged at intervals; the photoelectric sensor is used for sensing an aluminum tape located between the two supporting rotating wheels; and the controller is used for controlling the startup and stop of the quick uncoiling device according to the signals of the laser distance measuring sensor and the photoelectric sensor. Compared with a mode that operation and judgment are completely conducted by workers, the device can improve efficiency, and almost avoid accidents.
