The invention discloses a preparation device and method of a microfluidic tube for an intelligent robot motor. The device mainly comprises a roller, a heating cylinder, a cooling cylinder, a porous connecting block and a crimping machine, wherein the roller feeds a metal wire into the heating cylinder, the heating cylinder rapidly heats metal into liquid, the liquid flows into the cooling cylinderby means of the porous connecting block and is rapidly cooled to form an amorphous tube, and the tube is wound on a coiling machine to form a coiled material. The device is high in automation degree,can achieve full-thread and multi-procedure highly-integrated automatic production from wire feeding to final product, three microfluidic tube forming openings are formed, the production efficiency is high, through segmented heating and liquid nitrogen cooling, a non-crystallization degree is high, a length and a diameter of the produced microfluidic tube are not limited, a thickness of the produced microfluidic tube is 10 micrometers and 500 micrometers, for the tube with a thickness of 500 micrometers, the maximum error of the produced microfluidic tube is 10 micrometers, an amorphous rateof the produced microfluidic tube is not lower than 95%, and the problems of low production efficiency and low precision in the current amorphous tube forming process are solved.
