Technical Field

[0001] The utility model belongs to the technical field of test tube loading machines, and particularly relates to a test tube adjusting mechanism of a test tube loading machine. Background Art

[0002] Blood tests generally include routine tests such as blood routine, blood type, erythrocyte sedimentation rate, reticulocyte, blood biochemistry, blood immunity, and serum. Test tubes are commonly used blood sampling and testing utensils. During the testing process, test tubes need to be arranged and loaded onto the machine. Traditional test tube arrangement and loading are manual operations, which have problems such as low efficiency, and are prone to test tube breakage or incorrect instrument loading; the working process of the loading machine is to lift the test tubes to a designated position by a plate lifter, scan the barcodes on the test tubes through a scanning device to extract test tube information, and then the test tubes need to be placed on a test tube rack. Before this process, the test tubes are in a lying state, and the state of the test tubes needs to be adjusted, that is, the test tubes are adjusted from the lying state to the vertical state to facilitate placing the test tubes on the test tube rack by a manipulator.

[0018] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0020] As shown in the Figures 1 to 5 accompanying drawings, the present utility model provides a test tube adjustment mechanism, which includes a test tube adjustment device 5 provided on a workbench 16. The test tube adjustment device 5 includes an adjustment frame 51 and an adjustment plate 52. A long strip-shaped through groove 521 is provided on the adjustment plate 52. The length of the long strip-shaped through groove 521 is greater than the length of the test tube, and the width is greater than the diameter of the test tube body and less than the diameter of the tube cap. Specifically, after the test tube rolls onto the adjustment plate 52, the test tube body drops from the long strip-shaped through groove 521 and is hung on the upper end surface of the long strip-shaped through groove 521 through the tube cap, achieving the purpose of adjusting the test tube from a lying state to a vertical state. When applied to a test tube loading machine, it is convenient for the automation design of the test tube loading machine.

[0021] Preferably, after the test tube is adjusted to a vertical state, its position is in a state of uncertain coordinates within the long strip-shaped through groove 521. To facilitate the manipulator to clamp the test tube, the coordinates of the test tube need to be determined. The methods that can be used include determining by shooting with a bar code machine or determining the coordinates of the test tube in the vertical state by displacing the test tube to a specified position. In this embodiment, the coordinates of the test tube are determined by adjusting the position of the test tube. Specifically, the test tube adjustment device 5 further includes a first motor 53, a driving wheel 54, a driven wheel 55, a belt 56, and a pushing plate 57. The first motor 53 and the driven wheel 55 are connected to the adjustment frame 51. The driving wheel 54 is connected to the output shaft of the first motor 53. The driven wheel 55 is in transmission connection with the driving wheel 54 through the belt 56. The pushing plate 57 is connected to the belt 56. First, the first motor 53 drives the driving wheel 54, and the pushing plate 57 is transmitted to the far end of the long strip-shaped through groove 521 through the belt 56. After the test tube is adjusted to a vertical state through the adjustment plate 52, the first motor 53 drives the belt 56 again, and the pushing plate 57 is used to push the test tube to the other end of the long strip-shaped through groove 521. In this way, the coordinates of the test tube are determined, which is convenient for the three-axis manipulator to drive the clamping jaw to clamp the test tube and clamp the test tube to a specified position.

[0022] Preferably, since the test tube rolls freely onto the adjustment plate 52 after the test tube information is scanned by the bar code machine, in order to prevent the test tube from rolling out of the device, a baffle 58 is provided at one end of the adjustment plate 52 away from the test tube rolling device; it is used to block the rolling of the test tube so that the test tube can be smoothly adjusted to a vertical state through the adjustment plate 52.

[0023] Preferably, when the test tube is in a vertical state in the long strip-shaped through groove 521, only the test tube cap is exposed outside. In order to facilitate the clamping of the clamping jaw, the height of the test tube needs to be raised. The test tube lifting device 6 is also included, and the test tube lifting device 6 is connected to the adjustment frame 51; the test tube in the long strip-shaped through groove 521 is lifted in the Z-axis height through the test tube lifting device 6 to facilitate the clamping of the clamping jaw.

[0024] Preferably, this embodiment provides a specific test tube lifting solution. The test tube lifting device 6 includes a first air cylinder 61, a first clamping air cylinder 62 and a second pair of clamping jaws 63. The first air cylinder 61 is connected to the adjustment plate 52, the first clamping air cylinder 62 is connected to the output shaft of the first air cylinder 61, and the second pair of clamping jaws 63 is connected to the output shaft of the first clamping air cylinder 62. After the test tube is pushed to one end of the long strip-shaped through groove 521, the second pair of clamping jaws 63 is driven by the first clamping air cylinder 62 to clamp the test tube, and then the output shaft of the first air cylinder 61 retracts to raise the first clamping air cylinder 62 in the Z-axis, thereby driving the test tube to rise in the Z-axis. After the clamping jaw of the three-axis manipulator clamps the test tube, the first clamping air cylinder 62 drives the second pair of clamping jaws 63 to loosen, so that the clamping jaw of the three-axis manipulator can smoothly clamp the test tube to the designated position through the three-axis manipulator.

[0025] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution of the present invention and its inventive concept, and all such changes or substitutions should fall within the protection scope of the claims attached to the present invention.
