Optical fiber preform pick-and-place device

The invention discloses an optical fiber preform pick-and-place device, relates to the technical field of optical fiber preform placement, and is used for realizing multi-layer placement of optical fiber preforms and facilitating pick-and-place of the optical fiber preforms. Comprising an outer-layer support, a middle support and an inner-layer support which are sequentially arranged from outside to inside, idler wheels are arranged at the bottoms of the outer-layer support, the middle support and the inner-layer support, the outer-layer support is in sliding connection with the middle support, the middle support is in sliding connection with the inner-layer support, and multiple sets of supporting blocks are arranged at the tops of the outer-layer support, the middle support and the inner-layer support. And optical fiber preforms are placed on the two supporting blocks in the same group. The inner-layer bracket can move relative to the middle bracket, and the middle bracket can move relative to the outer-lay
