Automatic clamping and intubation device and method for micro-fluidic chip

The invention relates to an automatic clamping and intubation device and method for a micro-fluidic chip, and belongs to the field of micro-fluidic chip installation. A flow channel sorting structure is arranged in the applicable micro-fluidic chip, and pipelines for guiding flow are arranged at an inlet and an outlet of the flow channel sorting structure; the pipe inserting device comprises a base, a clamping platform is arranged on the base, and a pipe inserting mechanism is installed above the clamping platform through a pipe inserting mechanism fixing frame. Protruding bodies on the periphery of the clamping platform make contact with protruding bodies in the middle of the intubation mechanism fixing frame, it is guaranteed that the clamping platform can only move downwards by a certain distance when the clamping platform is pressed under the action of spring force, the clamping platform can return to the original position after the pressure is relieved, and automatic clamping and intubation of the micro-
