Description

Technical Field

[0001] The utility model relates to the technical field of sample tube information collection, and in particular to a sample tube information automatic input device. Background Art

[0002] Before collecting and testing the sample liquid in the sample tube, it is first necessary to enter the information of the sample tube. The barcode representing the sample tube information is generally affixed to the side wall of the sample tube near the bottom. When entering the information of the sample tube, the tester needs to hold the barcode scanner while picking up the sample tube on the placement plate or rack and enter the information of a single sample tube.

[0003] However, when there are a large number of sample tubes that need to be entered, manual operation is labor-intensive, prone to fatigue and inefficient. At the same time, when inspectors are entering information, in order to align the barcode with the barcode scanner, they often need to hold and rotate the sample tube, which can easily cause the sample tube to fall out of their hands. In addition, inspectors are prone to errors in the collection of sample tube information due to misplacing the sample tube. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a sample tube information automatic input device with high efficiency, low error rate, safety and reliability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0012] Furthermore, the width of the strip-shaped opening is smaller than the radial dimension of the circular placement groove.

[0013] The beneficial effects of the utility model are:

[0014] 1. After the sample tube is transported to the preset station of the rotating mechanism through the transverse movement mechanism, the two driven wheels are driven by the horizontal movement mechanism to gradually approach the sample tube until the two driven wheels contact the sides of the sample tube and cooperate with the driving wheel to clamp the sample tube. At the same time, the sample tube can be driven to rotate by rotating the driving wheel.

[0016] 3. The second position sensor of this solution can identify the height of the sample tubes in sequence. When the second position sensor detects an erroneous tube type with abnormal height, an alarm can be issued to facilitate manual removal of the sample tubes with the erroneous tube type.

DETAILED DESCRIPTION

[0020] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0021] like Figure 1 and Figure 2 As shown, the automatic sample tube information entry device of the present scheme includes a sample plate 1 and a transverse movement mechanism for conveying the sample plate 1, and a plurality of vertical circular placement grooves 5 are arranged on the sample plate 1, and the circular placement grooves 5 are used to place the sample tubes 24. The plurality of circular placement grooves 5 are arranged in a line in the horizontal direction, and a strip opening 6 is arranged on one side of the plurality of circular placement grooves 5, and the width of the strip opening 6 is smaller than the radial dimension of the circular placement groove 5 to prevent the sample tubes 24 from falling from the strip opening 6.

[0022] The transverse movement mechanism includes a conveyor belt 3 that is transmission-connected to the transverse movement motor 2. A transverse movement seat 4 for limiting the placement of the sample plate 1 is arranged on the conveyor belt 3. The transverse movement seat 4 is slidingly matched with the horizontal guide rail 23. A barcode scanner 7 is arranged on one side of the conveyor belt 3, and the detection end of the barcode scanner 7 is opposite to the strip opening 6 passing through the barcode scanner 7; rotating mechanisms for clamping the sample tube 24 and driving the sample tube 24 to rotate are arranged on both sides of the conveyor belt 3. The rotating mechanism includes a driving wheel 8 and a driven wheel 9 assembly respectively located on both sides of the conveyor belt 3. The driven wheel 9 assembly includes two driven wheels 9 arranged side by side with a gap, and the driving wheel 8 and the two driven wheels 9 are all arranged horizontally. The driving wheel 8 is transmission-connected to the rotating motor 10, and the driven wheel 9 assembly is transmission-connected to the horizontal moving mechanism. The driving wheel 8 cooperates with the two driven wheels 9 to clamp the sample tube 24 and roll with the side of the sample tube 24.

[0023] When the present scheme is implemented, a plurality of sample tubes 24 can be placed on the sample plate 1 in sequence, and then the sample plate 1 can be placed on the transverse shift seat 4. The transverse shift seat 4 can drive the plurality of sample tubes 24 on the sample plate 1 to move to the rotating mechanism and input information one by one, and there is no need to remove the sample tubes 24 from the sample plate 1, thereby avoiding the risk of the sample tubes 24 being taken or placed incorrectly or falling. When the information collection of the sample tubes 24 on the sample plate 1 is completed, the sample plate 1 is conveyed to the rear end of the conveyor belt 3 and the sample plate 1 is taken out.

[0024] The principle of information entry of the sample tube 24 in this scheme is as follows: after the sample tube 24 is transported to the preset station at the rotating mechanism through the transverse movement mechanism, the two driven wheels 9 are driven by the horizontal movement mechanism to gradually approach the sample tube 24 until the two driven wheels 9 contact the side of the sample tube 24, and cooperate with the driving wheel 8 to clamp the sample tube 24. At the same time, the sample tube 24 can be driven to rotate by rotating the driving wheel 8. At this time, the monitoring light path 22 of the barcode scanner 7 can dynamically track the barcode on the side wall of the sample tube 24 through the strip opening 6, thereby completing the automatic entry of the information of the sample tube 24.

[0025] In the specific implementation of this scheme, the driven wheel 9 assembly includes a base 11, on which a horizontal spring telescopic rod 12 is provided, and two driven wheels 9 are arranged at the front end of the spring telescopic rod 12, wherein the spring telescopic rod 12 can realize the elastic contact between the driven wheel 9 and the sample tube 24, thereby avoiding the extrusion and damage of the sample tube 24 due to rigid contact, and also providing a certain error margin for the stroke of the driven wheel 9.

[0026] The horizontal moving mechanism includes a bracket 13, on which a horizontal screw rod 15 is provided at one end, which is transmission-connected to a driving motor 14. A nut 16 is provided on the horizontal screw rod 15. The base 11 is mounted on the nut 16. The nut 16 is provided with a sliding block 17 that cooperates with the telescopic guide rail. In this scheme, the linear reciprocating motion of the two driven wheels 9 can be realized through the forward and reverse rotation of the horizontal screw rod 15, so that the driven wheel 9 cooperates with the driving wheel 8 to clamp and release the sample tube 24.

[0027] A travel piece 18 is also provided on the nut 16, and a first position sensor 19 cooperating with the travel piece 18 is provided on the bracket 13. The first position sensor 19 is preferably a proximity-type photoelectric sensor. When the two driven wheels 9 are in elastic contact with the sample tube 24, the travel piece 18 is separated from the first position sensor 19, and the first position sensor 19 can send a stop movement signal, thereby realizing the control of the stroke of the driven wheel 9.

[0028] A mounting plate 20 is provided on the bracket 13, and the mounting plate 20 is located at the front end of the driven wheel 9. A plurality of second position sensors 21 for detecting the height of the sample tube 24 are arranged in the vertical direction of the mounting plate 20. The second position sensor 21 is preferably a proximity-type diffuse reflection photoelectric sensor; the second position sensor 21 can identify the height of the sample tube 24 in turn, and when the second position sensor 21 detects an erroneous tube type with an abnormal height, an alarm can be issued to facilitate manual removal of the sample tube 24 of the erroneous tube type.
