In the process of pushing the test tube 10 toward the drop hole 112 by the pushing mechanism 310, the pushing mechanism 310 needs to stop before pushing the test tube 10 to the stopper 321, so as to wait for the next station to finish labeling on the previous test tube 10. When the pushing mechanism 310 stops operating, the test tube 10 will continue to move toward the drop hole 112 under the action of inertia, and when the test tube 10 moves to contact with the blocking member 321, the test tube 10 can be blocked by the blocking member 321 to stop sliding; after the previous test tube 10 is labeled at the next station, the pushing mechanism 310 may continue to push the test tube 10 to move toward the drop hole 112, and at this time, the test tube 10 may be pushed away from the stopper 321 by the pushing mechanism 310 and pushed to the drop hole 112 to enter the next station. The mode of transporting the test tube 10 by using the test tube transporting device 300 has high controllability, and the risk that the test tube 10 slides uncontrollably due to gravity is eliminated; and through setting up barrier mechanism 320, can prevent that test tube 10 from just getting into the risk of next station when the action of pasting the mark has not been accomplished yet in next station.

The working principle of the test tube transfer device 300 is as follows:

after the test tube 10 comes out of the test tube temporary storage device 200 and passes through the sliding groove 111, the test tube 10 can be hung on the bearing plate 110 by the feature that the diameter of the tube cap is larger than that of the sliding groove 111, and can be automatically adjusted to be in a vertical state; when the first test tube sensor detects that the test tube 10 enters the chute 111, the first motor 3111 is activated, so as to drive the pushing member 3122 to push the test tube 10 towards the drop hole 112 by means of the first synchronization belt 3112; when the pushing member 3122 moves to the front of the blocking member 321, the first motor 3111 stops to wait for the next station to finish labeling the previous test tube 10; when the pushing mechanism 310 stops operating, the test tube 10 will continue to move towards the drop hole 112 under the action of inertia, and when the test tube 10 moves to contact with the blocking member 321, the test tube 10 can be blocked by the blocking member 321 to stop sliding; after the next station finishes labeling the previous test tube 10, the first motor 3111 is started, so that the pushing member 3122 continues to push the test tube 10 to move toward the drop hole 112, and at this time, the test tube 10 can be pushed away from the blocking member 321 by the pushing member 3122 and pushed to the drop hole 112 to enter the next station.

As shown in fig. 13, the labeling device 400 is provided on the mounting frame 100, and the labeling device 400 is used for catching the test tube 10 dropped from the drop hole 112 and labeling the test tube 10.

As shown in fig. 14 to 16, the driving module 410 includes a first bracket 411, a second driving assembly 413 disposed on the first bracket 411, and a rotating roller assembly 412 disposed on the first bracket 411, wherein the rotating roller assembly 412 includes a driving roller 4121 rotatably disposed on the first bracket 411, and a driven roller 4122 rotatably disposed on the first bracket 411, the driving roller 4121 and the driven roller 4122 are disposed in parallel and spaced apart, and the second driving assembly 413 is drivingly connected to the driving roller 4121.

Specifically, the first bracket 411 is used for providing support for the second driving assembly 413 and the rotating roller assembly 412, two ends of the driving roller 4121 are rotatably connected with the first bracket 411 through bearings, and the driving roller 4121 can rotate around the axis of the driving roller 4121. The driven roller 4122 and the driving roller 4121 are arranged in parallel and at intervals, two ends of the driven roller 4122 are rotatably connected with the first bracket 411 through bearings, the driven roller 4122 can rotate around the axis of the driven roller 4122, and the second driving assembly 413 is used for driving the driving roller 4121 to rotate around the axis of the driving roller 4121.

More specifically, the second driving assembly 413 includes a second motor 4131 and a second timing belt 4132, a rotation driving shaft of the second motor 4131 is disposed in parallel with the driving roller 4121, the second timing belt 4132 is used to connect the driving shaft of the second motor 4131 and the driving roller 4121, and when the second motor 4131 is started, the driving shaft of the second motor 4131 is rotated, so that the driving roller 4121 is rotated by the second timing belt 4132.

As shown in fig. 14 and 17 to 19, the limiting module 420 includes a second bracket 421 fixedly connected to the first bracket 411, a third driving assembly 422 disposed on the second bracket 421, and a limiting assembly 423 rotatably disposed on the second bracket 421, the limiting assembly 423 includes a rotatable limiting roller 4231, the limiting roller 4231 is disposed in parallel with the driving roller 4121, the third driving assembly 422 is configured to drive the limiting assembly 423 to rotate toward or away from the rotating roller assembly 412, and the limiting roller 4231 can cooperate with the driving roller 4121 and the driven roller 4122 to form a limiting structure for limiting the test tube 10 after the limiting assembly 423 rotates toward the rotating roller assembly 412.

Specifically, the second support 421 is used to provide support for the third driving component 422 and the limiting component 423, and the second support 421 is fixedly connected to the first support 411. The restricting roller 4231 of the restricting assembly 423 is rotatable about an axis of the restricting roller 4231, and an axis of the restricting roller 4231, an axis of the drive roller 4121, and an axis of the driven roller 4122 are parallel to each other. The third driving assembly 422 is to drive the restricting assembly 423 to rotate so that the restricting roller 4231 can turn toward or away from the rotating roller assembly 412, and the distance between the restricting roller 4231 and the driving roller 4121 and the driven roller 4122 gradually approaches in the process that the restricting roller 4231 rotates toward the rotating roller assembly 412. In this way, when the test tube 10 is located between the drive roller 4121 and the driven roller 4122 and on the side close to the stopper roller 4231, the stopper roller 4231 can rotate toward the drive roller 4121 and the driven roller 4122 until abutting against the test tube 10 by the third driving unit 422, so that the position of the test tube 10 is defined by the drive roller 4121, the driven roller 4122, and the stopper roller 4231.

The labeling device 400 is divided into an active module 410 and a limiting module 420, and the active module 410 and the limiting module 420 are connected into a whole under the action of the first support 411 and the second support 421, so that the whole labeling device 400 is more compact in structure and occupies a small space. First, when the test tube 10 falls from the drop hole 112 (at this time, the test tube 10 falls between the drive roller 4121 and the driven roller 4122 and on the side close to the stopper roller 4231); the third driving assembly 422 acts to drive the limiting assembly 423 to turn to the rotating roller assembly 412 until the limiting roller 4231 contacts the test tube 10, and at this time, the position of the test tube 10 is limited under the action of the driving roller 4121, the driven roller 4122 and the limiting roller 4231; then the second driving assembly 413 drives the driving roller 4121 to rotate, so that the driving roller 4121 can drive the test tube 10 to rotate, so that the labeling position of the test tube 10 is opposite to the main label printing device 500, after the main label printing device 500 prints and peels off the label, the label is opposite to and contacts with the labeling position of the test tube 10, and the second driving assembly 413 continues to drive the driving roller 4121 to rotate, so that the label on the test tube 10 is tightly adhered by the driving roller 4121, the driven roller 4122 and the limit roller 4231 during the rotation of the test tube 10. Moreover, the limit roller 4231 turns or turns away from the rotating roller assembly 412 by means of the rotation of the limit roller 4231, so that the movable range of the limit roller 4231 is small, and the occupied space is small.

When the second test tube sensor 414 detects that the test tube 10 has fallen into a position between the driving roller 4121 and the driven roller 4122 and near one side of the stopper roller 4231, the third driving assembly 422 is activated to drive the stopper assembly 423 to move toward the rotating roller assembly 412.

Specifically, the second cuvette sensor 414 is a reflection-type photoelectric switch that can recognize glass, the second cuvette sensor 414 is disposed opposite to the gap between the drive roller 4121 and the driven roller 4122, and the second cuvette sensor 414 is located on the side of the drive roller 4121 and the driven roller 4122 away from the stopper roller 4231.

Further, the first holder 411 is further provided with a label sensor 415, and the label sensor 415 detects a position of a self-contained label (which is not a label attached by the labeling device 400 and is previously attached to the test tube 10) on the test tube 10. In this way, the position of the test tube 10 with the label can be detected by the label sensor 415, so that the starting position of the test tube 10 to be labeled can be known. In this manner, it is possible to facilitate the main label printing apparatus 500 to print a new label and peel the label so that the peeled label is opposed to and brought into contact with the starting position of the test tube 10 to be labeled.

So, can make and have great frictional force between drive roller 4121 and the test tube 10 for drive roller 4121 can drive test tube 10 smoothly and rotate at the rotation in-process, thereby makes things convenient for the subsides mark of test tube 10.
