The invention discloses a carbon fiber integrated laying device. The device comprises a material supply unwinding mechanism, a guide mechanism, a tension adjusting mechanism, a tension measuring mechanism, a re-feeding mechanism, a clamping mechanism, a shear mechanism and a compaction mechanism located below the bottom plate, wherein the material supply unwinding mechanism, the guide mechanism, the tension adjusting mechanism, the tension measuring mechanism, the re-feeding mechanism, the clamping mechanism and the shear mechanism are located above the bottom plate. Fibers on the material supply unwinding mechanism pass through the re-feeding mechanism, the clamping mechanism and the shear mechanism and then are compacted and cured on the surface of a mold through the compaction mechanism, in the above transmission process, guidance through the guide mechanism is achieved, the fiber bundle tension is adjusted passively through the tension adjusting mechanism, and the fiber bundle tension is measured through the tension measuring mechanism. Through elastic force effect of a spring, the distance between a compaction roller of the compaction mechanism and the surface of the mold can be passively adjusted, and therefore the device can meet the mold laying requirements of different curve faces and control requirements of a monofilament bundle.
