Description

Technical Field

[0001] The present invention relates to the technical field of test equipment, and more particularly to a desktop automatic test tube stopper flipping device. Background Art

[0002] During the laboratory testing process, opening a test tube with a test tube stopper is an essential step in the experimental procedure. With the improvement of the automation level of the detection production line, the traditional manual method of opening the lid is gradually being replaced by automated equipment. Currently, common automatic test tube flipping devices mainly use a motor-driven robotic arm to achieve the action. The flipping device mostly uses a linear motor or a rotary motor as the power source, and the motor drive usually requires a complex transmission mechanism to achieve the rotational movement of the flipping arm. However, such devices generally have problems of complex structure and high cost. Moreover, during the flipping process, due to the limitation of the driving method, the rotation angle and force control of the flipping arm are not precise enough, and it is easy to have poor adaptability to test tubes of different specifications. For test tubes of different diameters, traditional devices may need to frequently adjust parameters or replace components, increasing the volume and weight of the device, and causing test tube damage or incomplete flipping due to improper force control, which affects the experimental progress. Summary of the Invention

The flip arm is made of a metal material, and the end is of a concave card slot structure, which can adapt to test tube caps of different shapes such as circular and polygonal, improving the applicability of the device.

[0009] Further, the clamping cylinder and the rotary oscillating cylinder are connected with solenoid valves, and the solenoid valves are connected with a control system for controlling their operation. The pneumatic chambers of the cylinders are connected with the solenoid valves. By adjusting the opening and closing of the solenoid valves through the control system, the clamping and loosening of the clamping cylinder and the flipping action of the flip arm are realized.

[0010] Further, the control system includes an embedded control board. The control board uses a single-chip microcomputer as the core control unit, and also includes an interactive touch screen.

The U-shaped card slot is arranged outside the opening. The test tube is convenient and stable to place. By adjusting the installation height of the bracket on the frame through the long slot, the opening of test tube caps of different specifications can be realized.

[0012] Further, a sensor for sensing the test tube is arranged in the U-shaped card slot. The sensor is connected with the control system. After sensing the existence of the test tube, a signal is transmitted to the control system, and then the clamping and rotary oscillating actions are started.

[0013] Further, a protective outer cover is arranged on the outside of the frame, and the edge of the protective outer cover is rounded. The protective outer cover is made of acrylic material, is installed outside the device, and the edge is rounded, meeting the safety operation specifications of the laboratory.
