Description

TECHNICAL FIELD

[0001] The present application relates to a posture self-correcting formal test tube conveying device, belonging to the technical field of test tube conveying devices. BACKGROUND

[0002] In application scenarios such as clinical examination, environmental monitoring, food safety, etc. that require a large number of sample analysis, test tubes are usually used as the main container for loading the detected substances. In the actual operation process, the staff needs to batch transport the test tubes to the centralized detection mechanism or laboratory for analysis after loading the detected samples into the test tubes and covering the test tube covers.

[0003] In order to cope with the massive detection demand and realize efficient and automated sample flow, the existing technology generally adopts a test tube conveying pipeline system based on air pressure power. Specifically, the system generates airflow in a closed pipeline and uses air pressure difference as power to quickly convey the test tubes placed in the pipeline to the designated detection station. After the test tubes arrive at the detection station, they are usually received by a conveying belt and horizontally transmitted, and finally grabbed, uncapped, and separated by a mechanical hand for specific detection operations.

[0004] However, in the above-mentioned automated process, a key technical problem is the normalization control of the posture of the test tube. The posture of the test tube when it arrives at the conveying belt is random and may appear different postures of lying down. The subsequent mechanical hand grabbing operation, especially the uncapping or liquid sucking steps that need to perform precise positioning, strictly requires the test tube mouth to maintain an upright posture to ensure the accuracy of the operation and avoid sample spilling or cross contamination.

[0005] In order to solve the problem of chaotic test tube posture, the existing technology generally adopts a complex mechanical structure adjustment device. These mechanical structures adjust the posture of the test tube by physically constraining, colliding, and overturning the test tube on the conveying path. Although this kind of complex mechanical structure can achieve the function of posture adjustment to a certain extent, it exposes many inherent defects in actual large-scale and long-time operation, including poor stability and reliability, high failure rate, and high maintenance cost. This will limit the working efficiency of the overall design structure, and once a failure occurs, the entire detection line will be affected, leading to sample backlog, which seriously restricts the improvement of detection throughput.

[0021] In actual application, in order to more stably lift the test tube 2, as shown in Figure 2 and Figure 3As shown, a groove with a preset depth is arranged downwardly and inlaid on the upper surface of the top support 5-1 in the control electric lifting device 5, and the inner diameter of the groove is adapted to the outer diameter of the bottom of the test tube 2, that is, in the lifting process, the bottom of the test tube 2 falls into the groove on the upper surface of the top support 5-1, and the test tube 2 is lifted upward when the lower end of the test tube 2 is limited, and the lifting process becomes more stable.

[0022] The above design scheme is applied in practice, and in the vertical downward projection direction, the projection of the moving direction of the upper surface of the conveying belt 3-1 and the projection of the moving direction of the local segment of the rubber ring 1-3 between the two side rail devices 1 are in the same direction, that is, in one direction, each test tube 2 is conveyed by the conveying device to the central passage between the two side rail devices 1 for continuous conveying.

[0023] The above technical scheme is designed to be a posture self-correcting formal test tube conveying device, which includes two sets of side rail devices 1 respectively composed of side plates 1-1, rubber rings 1-3 and two electric control pulleys 1-2, which are arranged in parallel and side by side, and based on the synchronous work of the two electric control pulleys 1-2 in each side rail device 1 to drive the rotation of the rubber ring 1-3, each side plate 1-1 respectively supports the local segment of the rubber ring 1-3 facing the central passage between the two side rail devices 1, and the distance between the local segments of the rubber rings 1-3 on both sides of the central passage is adapted to the outer diameter of the test tube 2, and the local segments of the rubber rings 1-3 on both sides of the central passage lift the bottom of the edge of the test tube 2, so as to realize the movement and conveying of the test tube 2 in the central passage, and the design device has simple structure and obvious application effect, can accommodate test tubes 2 with different postures, and always keeps the mouth of the test tube 2 in an upward posture for conveying, thereby improving the work efficiency of the test tube 2 conveying.
