Description

Technical Field

[0001] This invention belongs to the technical field of automated sample testing equipment, and more specifically, relates to a sample testing channel avoidance scheduling platform. Background Technology

[0002] The booming development of the in vitro diagnostics industry has driven the continuous iteration and upgrading of medical laboratory automation technology. Currently, the IVD field is accelerating its transformation from single-machine automation to total laboratory automation (TLA). As the core component of the TLA system, the sample pretreatment system is responsible for a series of key processes, including sample receiving, centrifugation, capping and uncapping, sample dispensing, and sorting. Its level of automation and operational efficiency directly determine the throughput and reliability of the entire testing process.

[0003] In the entire sample pretreatment process, the transport and scheduling of sample racks is the core hub connecting various functional modules and ensuring system interoperability. Modern clinical laboratories need to process thousands or even tens of thousands of samples every day, and the sample types cover various priority scenarios such as emergency, routine, and physical examinations. This places extremely high demands on the transport and scheduling system; it not only needs to achieve orderly flow of sample racks, but also support dynamic priority management to ensure that high-priority samples are responded to first.

[0004] Currently, the sample rack transport systems used in the industry mainly rely on three types of technical solutions: First, single-channel circular transport lines, which rely on a circular track to complete the reciprocating transport of sample racks. However, this solution suffers from low channel utilization, cannot process multiple batches of samples in parallel, and is difficult to meet the needs of high-priority samples such as those from emergency departments. Second, multi-channel parallel transport lines, which divert and transport sample racks through multiple independent tracks. Although this can improve basic transport efficiency, there is a lack of effective linkage and coordination mechanisms between channels, and sample racks cannot be flexibly switched to backup channels. The structure is complex and the utilization rate is low. Third, point-to-point handling systems based on robotic arms, which directly transfer sample racks between workstations using robotic arms. Although this has high operational flexibility, it suffers from long robotic arm strokes, high equipment costs, and is difficult to adapt to high-throughput and continuous sample loading requirements. Summary of the Invention

[0005] In view of this, the present invention provides a sample detection channel avoidance scheduling platform, which can solve the problems of inflexible emergency sample avoidance mechanism and low transportation efficiency in the existing sample tube rack transportation system, making it difficult to adapt to high-throughput and continuous sample introduction requirements.

[0006] This invention is implemented as follows:

[0007] This invention provides a sample detection channel avoidance scheduling platform, wherein the platform is provided with multiple conveying channels, and a shuttle sample delivery mechanism is provided on the left and right sides of each conveying channel. The shuttle sample delivery mechanism is in contact and linked with each of the conveying channels through a gear linkage mechanism. The shuttle sample delivery mechanism is driven by a motor drive component and moves on the platform through a guide drive component.

[0008] The technical advantages of the sample testing channel avoidance scheduling platform provided by this invention are as follows: By setting up shuttle sample delivery mechanisms on both sides of the platform and configuring a gear-tooth linkage mechanism to achieve selective contact linkage between the shuttle sample delivery mechanism and the transport channel, it is possible to utilize the space of multiple channels for temporary sample storage and achieve flexible scheduling across multiple channels. Compared with the fixed channels or complex robotic arm handling in the prior art, this design allows the shuttle sample delivery mechanism to quickly switch between multiple transport channels, each corresponding to an independent transmission mechanism. The contact linkage design of the gear-tooth linkage mechanism ensures the reliability of power transmission, while meeting the flexible control of linkage when needed and disengagement when not needed, improving the flexibility of sample delivery and providing a reliable hardware foundation for the dynamic avoidance scheduling of emergency samples.

[0009] Based on the above technical solution, the sample detection channel avoidance scheduling platform of the present invention can be further improved as follows:

[0010] The conveying channel includes a transmission belt and pulleys at both ends. The inner side of the transmission belt meshes with the teeth on the pulleys through belt teeth to achieve transmission. The outer side of the transmission belt is also provided with belt teeth.

[0011] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the toothed design on both the inner and outer sides enables the transmission belt to achieve precise meshing transmission with the pulleys and tooth-to-tooth linkage with the transfer transmission belt of the transfer sample delivery mechanism. Compared with friction transmission or chain transmission, toothed transmission has the characteristics of no slippage, precise transmission ratio, and strong load-bearing capacity, ensuring the positional accuracy and synchronization of the sample tube rack when it is transferred between channels.

[0012] Furthermore, the pulleys at both ends of the multiple conveying channels are connected in series along the axis by a second fixed shaft, and the two sides of the pulleys are limited by limit clips to separate the spacing of the conveying channels.

[0013] The beneficial effects of adopting the above-mentioned improved scheme are as follows: The second fixed-axis series connection enables the support and positioning of pulleys in multiple conveying channels, ensuring the parallelism and height consistency of the pulley axes in each channel, allowing the sample tube rack to transition smoothly when conveying across channels. The limit clamps are used to achieve axial positioning of the pulleys, preventing axial movement during operation, and also serve to separate the channel spacing, thus standardizing the channel spacing.

[0014] Furthermore, the two ends of the second fixed axis are respectively fixedly connected to the support side baffles on both sides of the platform, and the bottom end of the support side baffles is fixedly connected to the platform by bolts.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the supporting side baffle provides a stable support foundation for the second fixed axis, and at the same time, as a protective structure on both sides of the platform, it can prevent the sample tube rack from tipping over or slipping during transportation.

[0016] Furthermore, a wide panel is installed between the support side baffles on both sides. The wide panel runs across the middle of multiple transmission belts, and a set of support platforms is provided on the upper surface of the wide panel at each position corresponding to one of the transmission belts. The support platform includes a receiving part and bent parts at both ends. The receiving part is located below the transmission belt, and the bent parts are bent downward and fixedly connected to the wide panel with bolts.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are as follows: The combination of the wide panel and the support platform forms the middle support system of the sample tube rack, solving the deflection and deformation problem of the long-span transmission belt when bearing the sample tube rack. The connecting section is located below the transmission belt, supporting the weight of both the transmission belt and the tube rack without affecting the normal operation of the transmission belt. The bending section design ensures that the connection point between the support platform and the wide panel is lower than the plane of the transmission belt, avoiding interference of the connecting bolts with the transmission belt or tube rack.

[0018] Furthermore, each of the conveying channels is separated by a baffle, and the bottom end of the baffle is fixedly connected to the wide panel.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the baffle spacing design realizes the physical isolation of adjacent transport channels, preventing the sample tube rack from tipping over due to vibration or displacement during transport; and ensures the independence of the channels and the accuracy of transport.

[0020] Furthermore, the ferry sample delivery mechanism includes a ferry trolley, a ferry transmission belt, and a guide slide. The ferry transmission belt is mounted on one side of the ferry trolley via transmission pulleys at both ends, and a housing for mounting the motor drive assembly is located on the other side. The inner side of the ferry transmission belt meshes with the teeth of the transmission pulleys, and the outer side of the ferry transmission belt also has teeth. A driven bevel gear is fixedly connected to the transmission pulley at one end extending outward. The motor drive assembly includes a drive motor and a driving bevel gear. The drive motor is fixedly mounted in the housing, and the driving bevel gear is fixedly connected to the output shaft of the drive motor. The driving bevel gear meshes with the driven bevel gear to drive the ferry transmission belt. The top of the guide slide is connected to the ferry trolley, and the bottom of the guide slide is driven by the guide drive assembly to displace the ferry sample delivery mechanism.

[0021] The advantages of adopting the above-mentioned improved scheme are as follows: the shuttle trolley has a compact structure, and the 90° rotation transmission between the drive motor output shaft and the shuttle drive pulley is achieved through bevel gear transmission, allowing the motor to be arranged horizontally in the machine compartment, which is convenient for installation in limited space. At the same time, the toothed design on the outer side of the shuttle drive belt enables it to provide power to the drive belt of the conveyor channel through the gear-tooth linkage mechanism, ensuring the stability of the sample tube rack during shuttle transportation.

[0022] Furthermore, the guide slide is connected to the bottom of the ferry trolley via a steering motor, used to drive the ferry trolley to adjust its angle; the guide drive assembly includes a second drive motor, a displacement transmission belt, and guide rails on both sides; the two ends of the displacement transmission belt are respectively connected by displacement pulleys, one end of the displacement pulley is fixedly connected to the output shaft of the second drive motor as the driving pulley, and the other end of the displacement pulley is mounted on the platform via a pulley mounting seat; the guide slide is slidably connected to the guide rails via sliders on both sides of its bottom end; the displacement transmission belt is connected to the guide slide via belt pressure blocks, used to drive the guide slide to move.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the output angle of the shuttle trolley can be adjusted relative to the guide slide by the steering motor drive connection, which meets the sampling needs of the equipment in the subsequent detection stage; the combination of displacement transmission belt and guide slide rail realizes the high-precision linear displacement of the shuttle sample delivery mechanism. The guide slide rail ensures the straightness of the displacement, and the displacement transmission belt realizes precise position control and fast response speed, which facilitates the shuttle trolley to switch back and forth between different conveying channels.

[0024] Furthermore, the gear linkage mechanism includes an ejector mechanism, a fixed shaft, and multiple sets of linkage gears. The multiple sets of linkage gears are installed on the fixed shaft corresponding to the position of each of the conveying channels. The ejector mechanism includes an electric push rod and a transverse push rod. Multiple sets of push blocks are fixedly installed on the transverse push rod, and the outer edge of the push block is provided with an inclined surface. Guide slides are respectively provided on the support side baffles on both sides, and the two ends of the fixed shaft are movably connected to the support side baffles corresponding to the guide slides.

[0025] The beneficial effects of the above-mentioned improved scheme are as follows: The ejection mechanism drives the transverse push rod through an electric push rod. Multiple sets of push blocks on the transverse push rod simultaneously act on the fixed shaft, causing the fixed shaft to move along the guide slide, thereby driving multiple sets of linkage gears to eject or retract synchronously. When the linkage gears eject, they mesh with the transfer drive belt and the corresponding conveyor channel drive belt, realizing the power linkage between the transfer mechanism and the conveyor channel; when the linkage gears retract, they disengage, and the transfer mechanism can move freely to other channels. The inclined push block design converts the linear motion of the electric push rod into the inclined movement of the fixed shaft, achieving smooth ejection and retraction of the linkage gears and avoiding rigid impact.

[0026] Furthermore, the sample transfer mechanism is provided in two sets, respectively located on both sides of the sample tube rack input end and sample tube rack output end of the conveying channel. The number of gear linkage mechanisms is two sets, and the extension and retraction directions of the ejection mechanism correspond to one set of the sample transfer mechanism.

[0027] The beneficial effects of adopting the above-mentioned improved scheme are as follows: The dual-shuttle mechanism design at both the input and output ends enables dual-end scheduling of the sample tube racks; specifically, the input-end shuttle trolley is responsible for introducing the sample tube racks to be inspected into the inspection channel, while the output-end shuttle trolley is responsible for transferring the sample tube racks to the next process. Two sets of gear-driven linkage mechanisms correspond to the input and output-end shuttle mechanisms respectively, allowing the selection of the shuttle trolley channels at both ends to be independent and without mutual interference. This design enables the platform to simultaneously process input and output requests from multiple sample tube racks, improving the system's parallel processing capability and overall throughput.

[0028] Compared with the prior art, the beneficial effects of the sample detection channel avoidance scheduling platform provided by the present invention are: it integrates the traditional separate multi-channel transportation and shuttle scheduling into a single platform, and through the coordination of the gear linkage mechanism and the shuttle sample delivery mechanism, it can realize the parallel transportation, selective linkage, cross-channel shuttle, and continuous automated processing of dynamic avoidance of sample tube racks. Specifically, the design of the double-sided toothed drive belt in the conveying channel and the top-out meshing mechanism of the gear-tooth linkage mechanism enable rapid, accurate, and reliable linkage between the sample transfer mechanism and any conveying channel. The combination of the second fixed-axis series pulley and limit card design, along with the wide panel and support platform, ensures the stability of multi-channel parallel conveying and the smoothness of sample rack transfer across channels. The bevel gear transmission and the angle turning design of the shuttle trolley driven by the steering motor in the sample transfer mechanism achieves both compact and highly reliable shuttle drive, while allowing adjustment of the output angle of the sample rack. In summary, the configuration of dual shuttle mechanisms and dual gear-tooth linkage mechanisms at the input and output ends enables independent scheduling of the sample rack at both ends, supports dynamic priority avoidance and parallel processing, and effectively improves the overall throughput of the system. The synergistic effect of the above-mentioned technical features fundamentally solves the technical problems of inflexible channel switching, lack of avoidance mechanism, and poor transport stability in the existing technology. It supports dynamic priority queueing and avoidance of emergency samples, meeting the stringent requirements of modern clinical laboratories for high efficiency, high flexibility and high reliability in sample processing. At the same time, the modular design makes it easy to flexibly configure the number of channels according to laboratory space and throughput requirements, improving the adaptability and scalability of the equipment.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] like Figure 1 The figure shows an embodiment of a sample detection channel avoidance scheduling platform provided by the present invention. In this embodiment, multiple conveying channels 10 are provided on the platform 14. A shuttle sample delivery mechanism 11 is provided on the left and right sides of the conveying channel 10 respectively. The shuttle sample delivery mechanism 11 is in contact and linked with a single conveying channel 10 through a gear linkage mechanism 12. The shuttle sample delivery mechanism 11 is driven by a motor drive component 13 and moves on the platform 14 through a guide drive component 15.

[0039] like Figures 2-5 As shown, in the above technical solution, the conveying channel 10 includes a transmission belt 101 and pulleys 102 at both ends. The inner side of the transmission belt 101 meshes with the pulley teeth on the pulley 102 through belt teeth to realize transmission. The outer side of the transmission belt 101 is also provided with belt teeth.

[0040] Furthermore, in the above technical solution, the pulleys 102 at both ends of the multiple conveying channels 10 are connected in series by a second fixed shaft 16 along the axis position, and the two sides of the pulleys 102 are limited by limit cards 17 to separate the spacing of the conveying channels 10.

[0041] The pulleys are connected to the second fixed shaft via bearings.

[0042] Furthermore, in the above technical solution, the two ends of the second fixed shaft 16 are fixedly connected to the support side baffles 18 on both sides of the platform 14, and the bottom end of the support side baffles 18 is fixedly connected to the platform 14 by bolts.

[0043] Furthermore, in the above technical solution, a wide panel 19 is installed between the two support side baffles 18. The wide panel 19 runs through the middle of multiple transmission belts 101, and a set of support platforms 20 is provided on the upper surface of the wide panel 19 at each position corresponding to a transmission belt 101. The support platform 20 includes a receiving part 201 and bent parts 202 at both ends. The receiving part 201 is located below the transmission belt 101, and the bent parts 202 are bent downward and fixedly connected to the wide panel 19 by bolts.

[0044] The wide panel 19 has bent connecting ears on both sides, and the connecting ears are fixedly connected to the mounting holes on the supporting side baffle 18 by bolts.

[0045] Furthermore, in the above technical solution, each conveying channel 10 is separated by a baffle 21, and the bottom end of the baffle 21 is fixedly connected to the wide panel 19.

[0046] Furthermore, in the above technical solution, the ferry sample delivery mechanism 11 includes a ferry trolley 111, a ferry drive belt 112, and a guide slide 113. The ferry drive belt 112 is mounted on one side of the ferry trolley 111 via drive pulleys 114 at both ends, and a housing for mounting the motor drive assembly 13 is provided on the other side. The inner side of the ferry drive belt 112 meshes with the teeth of the drive pulleys 114, and the outer side of the ferry drive belt 112 also has teeth. One end of the drive pulley 114 extends outward and is fixedly connected to a guide slide 113. The moving bevel gear 115 and the motor drive assembly 13 include a drive motor 131 and a driving bevel gear 132. The drive motor 131 is fixedly installed in the machine compartment. The driving bevel gear 132 is fixedly connected to the output shaft of the drive motor 131. The driving bevel gear 132 meshes with the driven bevel gear 115 to drive the ferry transmission belt 112 to move. The top of the guide slide 113 is connected to the ferry trolley 111. The bottom of the guide slide 113 is driven by the guide drive assembly 15 to drive the ferry sample delivery mechanism 11 to move.

[0047] Furthermore, in the above technical solution, the guide slide 113 is connected to the bottom end of the ferry trolley 111 via the steering motor 116, and is used to drive the ferry trolley 111 to adjust its angle; the guide drive assembly 15 includes a second drive motor 151, a displacement transmission belt 152, and guide rails 153 on both sides; the two ends of the displacement transmission belt 152 are respectively connected via displacement pulleys 154, one end of the displacement pulley 154 is fixedly connected to the output shaft of the second drive motor 151 as the driving pulley, and the other end of the displacement pulley 154 is mounted on the platform 14 via a pulley mounting seat 155; the guide slide 113 is slidably connected to the guide rails 153 via sliders on both sides of its bottom end; the displacement transmission belt 152 is connected to the guide slide 113 via belt pressure blocks, and is used to drive the guide slide 113 to move.

[0048] Furthermore, in the above technical solution, the gear linkage mechanism 12 includes an ejection mechanism 121, a fixed shaft 122, and multiple sets of linkage gears 123. The multiple sets of linkage gears 123 are installed on the fixed shaft 122 corresponding to the position of each conveying channel 10. The ejection mechanism 121 includes an electric push rod 1211 and a transverse push rod 1212. Multiple sets of push blocks 1213 are fixedly installed on the transverse push rod 1212. The outer edge of the push block 1213 is provided with an inclined surface 1214. Guide slides 181 are respectively provided on the support side baffles 18 on both sides. The two ends of the fixed shaft 122 are movably connected to the support side baffles 18 corresponding to the guide slides 181.

[0049] Multiple sets of linkage gears are connected to the fixed shaft through bearings, and limiters are provided at both ends to limit and prevent lateral displacement of the linkage gears; push blocks are set at the intervals between adjacent linkage gears to prevent interference.

[0050] The fixed end of the electric push rod 1211 is fixedly installed on the platform 14, and its output end is fixedly connected to the middle of the transverse push rod 1212. It is used to drive the transverse push rod 1212 to move and push the fixed shaft 122 to move so that the linkage gear 123 meshes with the outer teeth of the transmission belt 101 on the corresponding conveying channel 10 and the outer teeth of the transfer transmission belt 112 on the side transfer sample delivery mechanism 11, so as to achieve the transmission effect. That is, the transfer and delivery of the sample rack is realized by the movement of the transmission belt 101 of the conveying channel 10 corresponding to the position of the transfer sample delivery mechanism 11 at this time.

[0051] Furthermore, in the above technical solution, there are two sets of shuttle sample delivery mechanisms 11, which are respectively set on both sides of the sample tube rack input end and sample tube rack output end of the conveying channel 10. There are two sets of gear linkage mechanisms 12, and the extension and retraction directions of the ejection mechanism 121 correspond to one set of shuttle sample delivery mechanisms 11.

[0052] Specifically, the principle of this invention is as follows: During use, sample tube racks of different priorities are transported through multiple conveying channels. The shuttle trolley at the input end can load sample tube racks sequentially onto the regular channels, allowing sample tube racks of the same priority to be temporarily stored above the conveying channels and then transported in sequence by the shuttle trolley at the output end. If there are a total of 9 channels, channels 1-2 are emergency priority channels, and channels 3-9 are regular channels. When the system detects that a high-priority emergency sample needs to be queued, the shuttle trolley at the input end first uses a second motor to drive its sample tube rack along the guide rail to find the corresponding channel 1-2. The ejection mechanism on that side then establishes a linkage gear that engages with the shuttle drive belt of the shuttle trolley and the conveying channel's drive belt. The specific actions are as follows: an electric push rod pushes a horizontal push rod, causing the upper push block to contact the fixed shaft on that side. Using the inclined surface as a guide, the fixed shaft moves upward, driving the linkage gear on the fixed shaft to complete the engagement. At this time, the drive motor on one side of the shuttle trolley engages with the bevel gear transmission to drive the shuttle drive belt. At this time, under the action of the linkage gear, the transmission belt of the emergency priority channel and the shuttle transmission belt move in the same direction. The sample tube rack is transported to the top of the transmission belt of this channel and arranged in order according to the number of emergency samples (when the shuttle trolley at the input end is loading, the shuttle trolley at the output end can intermittently transport ordinary samples). After one or more sets of emergency samples are input, the shuttle trolley at the input end can immediately return to the sample tube rack loading operation in the regular channel. The shuttle trolley at the output end returns to the emergency priority channel first to transport emergency samples. The principle is the same as that at the input end. The connection is established by the ejection mechanism on this side. The emergency samples are transported by the transmission belt of the emergency priority channel to the shuttle transmission belt of the shuttle trolley, and the shuttle trolley is driven by the steering motor to make a 180° turn, which facilitates the sample tube rack to enter the next process, such as centrifugation. Centrifugation requires a batch of sample tubes to be carried out at the same time. Therefore, a batch of emergency samples can be centrally queued.

[0053] The superiority of this scheme lies in utilizing the independent movement of the sample delivery mechanisms on both sides, combined with a gear-tooth linkage mechanism to connect separate channels for sample transport. It achieves flexible handling of sample racks with different priorities within multiple channels. Lower-priority samples are transferred to regular channels for buffering, freeing up channels for emergency samples. After this process, the system resumes normal operation. It should be noted that this scheme does not require deliberate differentiation of priority channels. When the system detects an emergency sample entering, the input-end transfer trolley can directly select an empty channel or a channel with fewer sample racks for loading the emergency sample. The system settings can be adjusted according to actual needs. This application is merely intended to provide a hardware structure for achieving this technical effect.
