A kind of novel easy bar code location test tube
One, technical field
A kind of novel easy bar code location test tube is used on self-reacting device test tube bar code being positioned, and belongs to the laboratory and detects the self-reacting device field.
Two, background technology
During automation experiment is analyzed, instrument often need be distinguished bar code on the test tube, and because barcode position random and uncertain on the circular test tube if do not take special design arbitrarily to place test tube, can not guarantee that then the bar code reader of instrument carries out correct recognition to bar code on the test tube.Present existing solution is: artificially when putting test tube with the recognition mouth of bar code alignment bar code reader, or by instrument automatically with the test tube rotation, correctly distinguished until bar code alignment bar code reader.
Three, summary of the invention
The utility model is the alignment pin that designs unrestricted projection of one or more shapes or depression on test tube, place on the position at the test tube of instrument simultaneously and be provided with and the corresponding depressions or protrusions of alignment pin shape, utilize cooperatively interacting between projection and the depression to realize the location on its placement position of test tube, thereby be in a unique position all the time after making test tube be placed on the instrument test tube position, design the projection on bar code and the test tube or the alignment pin of depression simultaneously and become relatively-stationary position relation, thereby realize that barcode position over against bar code reader, makes things convenient for bar code reading.This design has solved the problem of self-reacting device test tube bar code recognition conveniently, easily.
Four, description of drawings
Fig. 1, Fig. 2 are respectively a kind of novel easy bar code location test tube and test tube and place the vertical view of position.
Five, the specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Among the figure, 1, test tube, 2, the alignment pin of test tube upper process, 3, test tube places the position, 4, test tube places the depression on the position, 5, the test tube holding tray.
As shown in the figure, the test tube 1 of the utility model design is placed on the test tube placement position 3 of the utility model design, the alignment pin 2 of test tube upper process cooperatively interacts with the depression 4 that test tube is placed on the position, test tube 1 is placed on the position 3 at test tube be in a well-determined position, simultaneously, the bar code of all test tubes all is positioned the alignment pin 2 relatively-stationary positions with the test tube upper process on the test tube holding tray 5, can be so that the bar code on all test tubes 1 all towards the outside of test tube holding tray 5, therefore can make things convenient for the recognition of bar code.
