Description

Technical Field

[0001] The utility model relates to a capillary automatic distribution device, which relates to the fields of experimental equipment and medical facilities technology. Background Art

[0002] During the production, transportation and use of capillaries, the capillaries are mostly stacked in one or more packages. This packaging method is not only very inconvenient to take in actual use, the capillaries are easily broken, but also there is a great risk of cross-contamination. When the user takes a single capillary from multiple capillaries, the stacked state of the capillaries will significantly affect the work efficiency. At the same time, cross-contamination of the unused capillaries will inevitably occur during repeated taking contacts, and the exposed packaging is also difficult to block pollutants such as dust and droplets. Therefore, it is necessary to optimize or improve the existing capillary taking method to improve the automation degree and work efficiency of capillary taking, and to avoid contamination.

[0010] The following is a detailed description of the specific embodiments of the present utility model according to a specific implementation scheme of the present utility model.

[0011] The present utility model provides a capillary automatic dispensing device, which is characterized in that it includes: an outer shell, a capillary storage bin, a conveying mechanism, an electric push rod, a photoelectric sensor, a base, and a control mechanism. The usage steps are as follows:

[0012] 1. Place a batch of capillaries in the capillary storage bin 2. The width of the slit 2a is slightly larger than the outer diameter of a single capillary, and the capillaries are in a single-row side-by-side form in the slit;

[0013] 2. When the control mechanism controls the stepper motor 3a to start, the stepper motor 3a drives the conveyor wheel 3b;

[0014] 3. When the conveyor wheel 3b rotates to its groove 3c communicating with the capillary storage bin 2, a single capillary enters the groove 3c from the capillary storage bin 2; when the conveyor wheel 3b rotates to its groove 3c not communicating with the capillary storage bin 2, the capillary is blocked by the conveyor wheel 3b and cannot move;

[0015] 4. The capillary in the groove 3c continues to rotate with the conveyor wheel 3b and drops downward;

[0016] 5. The dropped capillary is received by the inclined plate 6a and slides down along the inclined plate 6a to the capillary card slot 6b and is stabilized by the capillary card slot 6b;

[0017] 6. The capillary is pushed by the electric push rod 4, moves in the capillary card slot 6b and moves out of the outer shell 1;

[0018] 7. The photoelectric sensor 5 detects that a capillary is pushed out and transmits a signal to the control mechanism;

[0019] 8. The control mechanism controls the conveying mechanism and the electric push rod 4 to stop after receiving the transmitted signal.
