Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal processing, in particular to an automatic test tube feeding and code scanning device. Background Art

[0002] In the use of automated centrifugal pre-processing workstations, many functions require knowing the test tube information in advance before proceeding to the next step. Since it is impossible to ensure that the barcode of each product is always facing in one direction when the product is in circulation, most automated centrifugal pre-processing workstations will use a robot to grab the test tube to a separate scanning position when scanning is required, and then rotate it through a robot or other device to determine the next step of the test tube. This method will increase the time by 5-8 seconds for each test tube, greatly reducing the efficiency of the automated centrifugal pre-processing workstation; or scan the barcode before feeding, this method cannot avoid the impact of abnormalities that occur during the feeding process on the barcode sequence.

[0023] Embodiment 1:

[0024] See also Figure 1 - Figure 4 The utility model of the automatic test tube feeding and scanning device comprises: a barcode scanner 16; an adjustment component, the adjustment component is used to adjust the test tube to carry the barcode to rotate toward the barcode scanner 16, the adjustment component comprises a stepper motor 10, a driving wheel 11 is installed on the stepper motor 10, a docking groove 15 for docking the test tube is provided on the driving wheel 11, a cover plate 5 is sleeved on the surface of the driving wheel 11, a mounting hole 6 adapted to the driving wheel 11 is provided on the cover plate 5, a driving strip 7 is inlaid on one side of the mounting hole 6, the driving strip 7 partially protrudes from the mounting hole 6, and the stepper motor 10 drives the test tube to rotate until it has an interference fit with the driving strip 7;

[0025] The driving bar 7 is installed on the axis between the barcode scanner 16 and the driving wheel 11 .

[0026] The bottom of the driving wheel 11 is fixedly connected with a mounting shell 1 , and a mounting cavity 2 for mounting the stepper motor 10 is provided inside the mounting shell 1 . A detection window 4 is provided at one end of the mounting shell 1 facing the barcode scanner 16 .

[0027] A photoelectric sensor 12 is also provided on the side of the mounting shell 1 away from the inspection window.

[0028] This embodiment, when used:

[0029] The test tube is inserted into the docking groove 15 of the driving wheel 11, and then the stepper motor 10 is started to make the driving wheel 11 carry the test tube and rotate toward the driving bar 7. When the driving wheel 11 carries the test tube and rotates, it will have an interference fit with the driving bar 7, so that it is squeezed by the driving bar 7 and rotates passively, that is, the position of the test tube barcode can be adjusted;

[0030] Because the driving bar 7, the detection window 4 and the barcode scanner 16 are on the same axis, the rotation of the test tube will rotate under the barcode scanner 16, thereby ensuring that the barcode is recorded by the barcode scanner 16. If it is not recorded, it means that it is abnormal; until the driving wheel 11 brings the test tube to the detection range of the photoelectric sensor 12, the driving wheel 11 stops rotating and waits for the manipulator to grab the test tube. The manipulator will determine whether the test tube is abnormal based on whether the barcode on the test tube is successfully recorded;

[0034] The cover plate 5 is provided with a fitting opening 8 which is connected to the mounting hole 6 , and the top downward end of the loading rack 13 is installed inside the fitting opening 8 .

[0035] By setting the feeding assembly, the test tube can slide from the V-shaped slide groove into the docking groove 15, so as to facilitate the rapid entry of the bar code of the test tube and facilitate docking with other equipment.

[0036] Further, the loading rack 13 includes two symmetrically arranged mounting plates, and a feed slot channel is provided between the mounting plates; a docking opening 3 connected to the mating opening 8 is provided on one side of the mounting shell 1 close to the feed assembly, and this arrangement allows the test tube to be vertically translated into the docking slot 15.

[0037] In the above embodiment, the loading rack 13 and the mounting shell 1 are both mounted on the bottom plate 14 , and the stepper motor 10 is mounted on the bottom plate 14 of the mounting cavity 2 via the motor seat 9 .
