Exotic hadrons are new observed states with the structures beyond a quark-antiquark pair (for mesons) or three quarks (for baryons). Among them, fully heavy tetra- and pentaquarks have been attracted more attention because these large energy states can be accessed experimentally and can easily be distinguished from other states. Without light flavor contaminations, these are quite ideal prototypes to expand our understanding of heavy quark dynamics. In the present work, our aim is to study the production mechanism of heavy pentaquarks with the spin-parity assignment 
through fragmentation process and estimate their production rate at 
colliders. To do, we suppose the diquark-diquark-antiquark model for their inner structure and determine their fragmentation functions in leading order of perturbative QCD. Results are compared with those obtained through tightly compact picture where constituents are tightly bound by the color force.
