[0016] The present application will be further illustrated below in conjunction with the drawings and specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the present application and are not used to limit the scope of the present application. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.

[0017] As Figures 1-3As shown, this utility model discloses a chip loading and unloading device developed based on microfluidic technology, including a stage 4. The stage 4 is composed of a chip positioning pin 10, a spherical groove 11, a concave platform 12, a double-sided rack 5 protruding from the bottom, and a drive gear 6. A first transmission gear 1 and a second transmission gear 9 mesh on both sides of the drive gear 6. The first transmission gear 1 is connected to a first residual gear 2 via a first transmission shaft 3; the second transmission gear 9 is connected to a second residual gear 7 via a second transmission shaft 8. Both the first residual gear 2 and the second residual gear 7 mesh with the double-sided rack 5. The first transmission gear 1 and the second transmission gear 9 are fixed in a specific position by a positioning shaft. Both the first transmission gear 1 and the second transmission gear 9 mesh with the drive gear 6, which is connected to an external motor via a shaft passing through the base.

[0018] Chip positioning pins 10 are distributed at each of the four corners of the concave platform 12.

[0019] The concave platform 12 has spherical grooves 11 with a depth greater than that of the concave platform 12 distributed on both sides.

[0020] like Figure 3 As shown, the toothed portions of both the first and second defective gears 2 and 7 have a central angle of 72°.

[0021] In this embodiment, the concave platform is used to store microfluidic chips. The chip positioning pins are evenly distributed at the four corners of the concave platform groove to achieve precise positioning of the microfluidic chips during storage. The spherical grooves are symmetrically distributed on both sides of the concave platform, and the groove depth is greater than the groove for storing the chips, so as to realize convenient storage and retrieval of microfluidic chips. The guide rail grooves are symmetrically distributed on the side of the concave platform, which can synchronously position the stage, so that the stage is always located at the axial symmetry axis of the entire device when moving. The double-sided rack is fixed in the middle of the bottom of the concave platform and its rear end is slightly longer than the concave platform, so as to realize the reciprocating motion of the stage.

[0022] The missing gear is mounted on the transmission gear with its toothed parts facing the same direction to prevent it from meshing with the rack at the same time, which would cause structural damage.

[0023] In operation, the motor is turned on. When power is transmitted to one side of the defective gear and it meshes with one side of the double-sided rack, the gear rotates forward, sending out the rack and the platform on it. The motor stops once the platform reaches the designated location. The pre-drilled positioning hole of the chip is aligned with the positioning pin and placed in place. After placement, the motor is turned on again. When the other side of the defective gear meshes with the rack, the gear rotates in reverse, sending the rack and platform back into the device, thus achieving automatic chip feeding and feeding.

[0024] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be noted that, in order to more directly show the device structure, part of the structure of the shell bottom plate is omitted in the display process to ensure that the gear structure can be directly and accurately displayed. It can be understood that the changes, modifications, replacements and deformations of the embodiments are made without departing from the principle and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
