1. A microfluidic sample processing device, comprising:
a tray apparatus, for accommodating a reagent and a chip clamp for mounting a microfluidic chip;
a mechanical arm, having a connecting head for connecting the chip clamp, a gas flow channel for communicating with an inner cavity of the chip clamp being arranged in the connecting head;
a negative pressure suction apparatus, for providing negative pressure to the gas flow channel of the connecting head;
a lifting apparatus, for driving the connecting head to rise and fall to connecting the chip clamp or make the chip clamp insert into or separate from the reagent; and
a translation apparatus, for driving the connecting head to move to above the chip clamp or above the reagent;
wherein, the tray apparatus is positioned below the mechanical arm, and the mechanical arm is arranged on the translation apparatus and is connected to the lifting apparatus,
wherein one or more kits are mounted on the tray apparatus, each kit comprises a kit body, and the kit body is provided with a waste liquid collection well for inserting the chip clamp and storing waste liquid and one or more reagent wells for storing reagents, and
wherein the kit body is further provided with a chip return well for depositing the chip clamp, the tray apparatus further comprises a baffle plate, and a part of the chip return well is located directly under the baffle plate.
