Automatic fiber coiling device

The invention relates to an automatic fiber coiling device. The automatic fiber coiling device is used for automatically coiling an optical fiber connected with an optical device, and comprises a carrier, an optical fiber guide assembly and a power device, the optical device is placed on the carrier, steel wire ropes are connected to the two opposite ends of the carrier, and the steel wire ropes pull the carrier to move away from/towards the power device along a sliding rail; the power device comprises a first rotating disc, the optical fiber penetrates through the optical fiber guiding assembly to be bonded to the first rotating disc, and the optical fiber is coiled around the first rotating disc when the first rotating disc rotates; and the power device further comprises a second rotating disc, and the second rotating disc drives the steel wire ropes to move and be coiled when rotating. According to the scheme, the purpose of automatically coiling the optical fiber around the first rotating disc through the
