Description

Technical field:

[0001] The present invention relates to the technical field of reagent detection equipment, and more particularly to a two-track fully automatic sample tube conveying mechanism for sample detection. Background technology:

[0002] When testing various substances such as blood and saliva, they need to be placed in a sample bottle, which is then placed on a conveyor mechanism. The conveyor mechanism transports the sample bottle to the testing sampling location, and the sample is extracted by the sampling device. However, the existing conveyor mechanism is generally a conveyor belt that transports the sample bottles one by one. During the conveying process, there is no limit mechanism. That is, the material in the previous sample bottle has not yet been extracted, and the next sample bottle has already been delivered, which can easily affect the sampling process and make it difficult to align the sample bottle for sampling, resulting in poor results. In addition, after the sample bottle is sampled, the sample bottle needs to be manually picked up, which is labor-intensive and ineffective. Summary of the invention:

[0054] Working principle: When in use, place the sample rack 300 with the sample bottles to be tested into the feed basket 12, and insert the guide rail 14 into the groove formed in the middle of the bottom surface of the sample rack 300, with the barcode facing the front;

[0055] During use, the sample rack 300 is pushed forward by the sample pushing plate 21 of the sample pushing device 20. When it passes through the counting sensor 2, it is sensed by the counting sensor 2 and counted until the sample rack 300 leans against the rear transverse plate of the expedited position. At this time, it is just in the feed transfer channel. The pushing distance of the sample pushing plate 21 of the sample pushing device 20 is controlled by the sensor provided thereon corresponding to the sensing part on the second support frame fixed on the second conveyor belt 24. This is a conventional setting structure and will not be described in detail here. The corresponding subsequent controls also adopt this type of structure and will not be repeated later.

[0056] Then, the sample rack 300 is pushed to the right by the lateral pushing block 41 of the lateral pushing mechanism 40. In order to prevent the lateral pushing block 41 from pushing the sample rack 300 in front of the material receiving basket 13 to the right, the spacing between the partition block 16 and the rear oblique stopper 17 is smaller than the width of the sample rack 300, so that the sample rack 300 of the material receiving basket 13 will not be pushed to the right. In addition, the lateral pushing block 41 is hinged by a torsion spring. When the sample rack 300 in front of the material receiving basket 13 cannot be pushed to the right, the lateral pushing block 41 can be turned over so that it does not extend out of the lateral moving slot 151, and can continue to move until it reaches the sample rack 300 at the feed transfer channel and push it to the right. When passing the barcode scanner 1, the barcode on it can be scanned and recorded. At the same time, it will be pushed into the conveyor belt 51 and transported to the right by the conveyor belt 51. When the sample rack 300 is moved to the right, the upper bending limit portion 921 at the top of the vertical swing rod 92 is used to block the sample rack 300. After the sampling of the sample rack 300 in the front is completed, the output shaft of the limiting stepper motor 91 rotates so that the upper bending limit portion 921 no longer blocks the sample rack 300. The swing is controlled by the two limit switches 3 for sensing limit.

[0057] Then, the sample rack 300 can continue to be transported to the right.

[0058] When the sample rack 300 being transported rests on the sample suction blocking block 98, the sensing end of the proximity switch of the sample suction moving block 97 senses the sample rack 300, indicating that it has moved into position. At this time, the subsequent sampling equipment extends the sampling tube into the first sample bottle at the right end of the sample rack 300 for sampling. After completing one sample, the sample suction conveyor belt 95 can be used to move the second sample bottle of the sample rack 300 to the sampling position for sampling, which is very convenient.

[0059] After the sampling is completed, the sample suction blocking block 98 continues to move to the right, and is blocked by the right side wall of the horizontal through-slot formed on the corresponding side baffle, and then flipped over so that it is no longer above the conveyor belt 51, thereby no longer blocking the continued transportation of the sample rack 300;

[0060] The subsequent sample rack 300 continues to be transported to the right until it enters between the two transfer grippers 505 and senses the sample rack 300 through the sensors fixed on the conveyor rack 201 around it. At this time, the control host can control the two transfer grippers 505 to move forward. During the forward movement of the sample rack 300, a horizontal pad is fixed on the top surface of the right part of the middle horizontal plate of the conveyor rack 201. The top surface of the horizontal pad is flush with the top surface of the upper belt body of the conveyor belt 51 and the return conveyor belt 52. Then, through the two transfer grippers 505, the sample rack 300 is moved forward. The gripper 505 moves forward and moves the sample rack 300 to the top surface of the upper belt body of the return-to-warehouse conveyor belt 52. At this time, the sample rack 300 can be moved to the left and conveyed by the return-to-warehouse conveyor belt 52 until it is conveyed to the left part of the fourth conveyor belt 62, which is just opposite to the front of the material receiving basket 13. The return material pushing plate 31 of the return-to-warehouse pushing device 30 is in front of the left part of the return-to-warehouse conveyor belt 52. It pushes backward to push the sample rack 300 backward and finally push it into the material receiving basket 13 for collection, which is very convenient.

[0061] Among them, when the equipment is in operation, when it is necessary to expedite the test sample, the sample rack 300 containing the sample bottles that need to be expedited can be inserted into the expedited position. At the same time, the sample injection push plate 21 of the sample injection push device 20 retreats to its position. At this time, the expedited transverse plate 76 is pushed backward to place the expedited position in the feed transfer channel. The transverse push block 41 of the transverse push mechanism 40 is moved transversely to push it to the right. The subsequent test is the same as conventional testing, which is very convenient and effective.

[0062] Finally, the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the scope of patent protection of the present invention should be defined by the claims.
