Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary application of medical equipment, in particular to a biological sample tray pressing device. Background Art

[0002] In the existing medical tube picking technology, due to the small diameter of the sample tube and the high storage density, the picking of the sample tube requires high precision. The sample tray itself has deviations and the positioning fixture has deviations, which leads to frequent deviations in the tube picking, which in turn causes the butler tray to move or be lifted up.

[0003] In the existing transfer and storage of sample tubes, due to the small diameter of the sample tubes and the high storage density, vision or other devices are generally used for positioning. The vision cost is high and is greatly affected by the external environment. Ordinary positioning cannot achieve accurate positioning. When the sample rack is taken out from a low temperature, the sample tube may be frozen with the tube rack tray, causing the tube rack tray to be lifted up when the tube is picked up.

[0004] For this reason, it is urgent to develop a device that can ensure that the pipe rack tray is reliably positioned when the pipe is picked. Summary of the invention

[0005] In view of the above problems, the utility model provides a biological sample tray pressing device, which ensures the reliable positioning of the tube rack tray and the accuracy and reliability of tube picking.

DETAILED DESCRIPTION

[0024] A biological sample tray pressing device, see Figure 1 and Figure 2 , which includes a base 10, a positioning fixture 20, a vertical mounting plate 30, a pressure plate 40, and a lifting mechanism 50; the pressure plate 40 specifically includes a frame 41 and a notch 42;

[0025] In specific implementation: two groups of identical positioning fixtures 20 arranged in parallel are provided on the upper surface of the base 10, and the two groups of identical positioning fixtures 20 are combined to form a rectangular outline, and two groups of corresponding trays 60 are placed in the corresponding positioning fixtures 20, and the frame 41 of the pressure plate 40 is arranged in the shape of the outline of the two groups of trays 60, and the notch 42 of the pressure plate 40 is two groups of rectangular notches arranged at intervals, which ensures that the lifting mechanism 50 controls the pressure plate 40 to press the two groups of trays 60 at the same time;

[0026] The vertical mounting plate 30 is fixedly mounted at the center of one side of the base 10 . A lifting mechanism 50 is fixedly disposed on the vertical mounting plate 30 . The lifting mechanism 50 drives the pressure plate 40 to move up and down.

[0027] During specific implementation, the lifting mechanism 50 includes a driving motor 51, a synchronous belt 52, a driving wheel 53, and a driven wheel (obstructed in the figure, belonging to the existing mature technology). The driven shaft of the driven wheel passes through the vertical mounting plate 30 and is provided with a driven housing 70. The output end of the driving motor 51 is connected to the driving wheel 53, and the driving wheel 53 is connected to the driven wheel below through the synchronous belt 52. One side of the synchronous belt 52 is fixedly connected to the corresponding convex connection structure 43 of the pressure plate 40 through the connection structure 80. The driving motor 51 drives the pressure plate 40 to lift and lower. The convex connection structure 43 of the pressure plate 40 also includes a rear convex stop protrusion 431. A limit block 90 is provided at the upper center position of the vertical mounting plate 30. The maximum upward stroke of the rear convex stop protrusion 431 is limited by the limit block 90 to ensure that the entire structure will not derail.

[0028] The lifting mechanism 50 is fixedly mounted on the vertical mounting plate 30, and guide rails 54 are arranged on both sides of the vertical mounting plate 30 facing the pressure plate 40. The upper part of the pressure plate 40 is embedded in the guide rails 54 through the guide rail pair 44. The connecting structure 80 is located at the upper part of the center position in the length direction of the pressure plate 40, which ensures that the lifting mechanism 50 drives the pressure plate 40 stably and reliably.

[0029] The guide rail pair 44 on one side is also connected to the insert 46 through a bending piece 45. The corresponding side of the back side of the vertical mounting plate 30 is fixed with a guide groove 31. The front protrusion 47 of the insert 46 is embedded in the guide groove 31. The front protrusion shape of the front protrusion 47 is set to imitate the cross-sectional shape of the guide groove 31, which ensures further reliable driving of the lifting mechanism 50 corresponding to the pressure plate 40.

[0030] Its working principle is as follows: when the sample tray is placed on the positioning fixture by the robot, or when the empty tray is placed in the positioning fixture, the lifting mechanism drives the pressure plate to descend and presses the frame of the tray tightly, which ensures the reliable positioning of the tube rack tray and the accuracy and reliability of tube picking.
