[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] Reference Figure 1 The present specific implementation adopts the following technical scheme: a rotor for an automatic positioning centrifuge, comprising a rotor body 1, a hanging pin 2, a hanging basket 3 and an adapter 4, wherein the rotor body 1 is an I-shaped rotor, and hanging pin mounting holes 11 are reserved on the four arms of the rotor body 1, the hanging pin mounting holes 11, the four hanging pins 2 are inserted into the four arms of the rotor body 1 through the hanging pin mounting holes 11 and fixed with nuts 5, the positioning groove 31 on the side of the hanging basket 3 is aligned with the hanging pin 2 and placed in the rotor body 1, and the adapter 4 is placed in the hanging basket 3.

[0018] The center of the rotor body 1 is provided with a rotation center hole 12, and the rotor body 1 can rotate around the rotation center hole to generate centrifugal force during centrifugation.

[0019] The bottom of the hanging basket 3 is rectangular, with a first limiting wall 32 on the left and right sides, and a second limiting wall 33 on the upper and lower sides. The bottom surface of the first limiting wall 32 is a vertical surface, and the top is chamfered to facilitate the insertion of the adapter; a positioning groove 31 is provided at the center of the outer side of the first limiting wall 32, and the top of the notch of the positioning groove 31 is semicircular and the bottom is rectangular, which is convenient for matching with the cylindrical hanging pin; the width of the second limiting wall 33 is smaller than that of the first limiting wall 32, and the position is centered. There is a large space on the side of the second limiting wall 33 for taking the adapter by hand. This space can also be used as a grasping space for the mechanical claw design when it is subsequently added to the automated production line.

[0020] The adapter 4 comprises a large rectangular bottom surface 41 and a small rectangular top surface 42, the large rectangular bottom surface 41 and the small rectangular top surface 42 form a step, and four placement holes 43 are arranged in the middle of the small rectangular top surface 42. This step design not only allows the user to take the adapter by hand, but also can be used as a grasping space for the mechanical claw design when it is subsequently added to the automated production line.

[0021] like Figure 5 As shown, the assembly steps of this specific embodiment are as follows:

[0022] 1. When assembling the rotor, first insert the four hanging pins into the four arms of the rotor body through the round holes, and then tighten them with nuts to fix their relative position with the rotor body.

[0023] 2. Align the positioning groove on the side of the hanging basket with the hanging pin and put it into the rotor body. The hanging basket can move in a circle around the hanging pin.

[0024] 3. Place the adapter into the hanging basket. After the adapter is placed in, its displacement will be restricted by the limit wall, and its relative position with the hanging basket will be fixed, and it will move with the movement of the hanging basket.

[0025] The working principle of this specific implementation is as follows: Figure 6 As shown, during centrifugation, the rotor body rotates around the center hole. Under the action of centrifugal force, the hanging basket rotates around the hanging pin, and the adapter and the hanging basket are relatively fixed. Finally, the adapter and the hanging basket rotate 90° around the hanging pin, and the horizontal becomes vertical. After the centrifugation is completed, it changes from vertical to horizontal and returns to the initial state. When the hanging basket and the adapter are in a horizontal state, there is sufficient space above and below and left and right of the adapter to facilitate the gripping design of the mechanical claw.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
