Description

Technical Field

[0001] This invention belongs to the field of biological sample processing technology, and in particular relates to an automatic tray conveying device. Background Technology

[0002] In cytogenetic testing procedures such as chromosome karyotype analysis, cell suspension processing is typically performed by upstream equipment such as automated harvesters, while subsequent steps such as slide preparation and staining are carried out by downstream equipment. After sample pretreatment, the sample tray containing centrifuge tubes needs to be transferred from the upstream harvester to the downstream equipment for subsequent slide preparation and other processes.

[0003] Currently, the transfer of sample trays mainly relies on manual handling, which is inefficient in practical applications and slows down the overall testing speed. Moreover, manual handling can easily introduce contamination, affecting the condition of the specimen and the subsequent staining effect.

[0004] Although a small number of automated technologies related to automatic transfer of laboratory trays have emerged in the industry, such as the tray transfer mechanism disclosed in Chinese patent (publication number: CN210735534U), this transfer mechanism adopts a simple translation structure, which has the problem of occupying a large space and is not conducive to the integrated layout of upstream and downstream equipment in a compact space. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pallet conveying device to address the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] An automatic pallet conveying device includes a horizontal transmission mechanism and a horizontal base;

[0008] The horizontal transmission mechanism includes:

[0009] A first transmission assembly is used to drive a movable pallet to move relative to the horizontal base;

[0010] The second transmission assembly includes a fixed guide seat fixed to the horizontal base, and a transmission belt and a conveyor slider on the movable pallet.

[0011] The conveying slider is used to receive the sample tray;

[0012] The transmission belt on the pallet extends along the moving direction of the moving pallet, and the conveying slider is connected to the transmission belt on the pallet;

[0013] The movable pallet is provided with an elongated clearance groove extending along the moving direction of the movable pallet, and the fixed guide seat passes through the elongated clearance groove and is engaged with the transmission belt on the pallet.

[0014] When the first transmission component drives the moving pallet to translate, the fixed guide seat remains stationary. The transmission belt on the pallet moves with the moving pallet as a whole and is pulled by the fixed guide seat, thereby driving the transmission slider to slide in the same direction relative to the moving pallet.

[0015] In the above-mentioned automatic pallet conveying device, the fixed guide seat is located in the area covered by the path of the moving pallet moving horizontally relative to the horizontal base, and the elongated clearance groove has a first end and a second end opposite to each other. At the maximum stroke, the second end is farther away from the horizontal base than the first end.

[0016] Furthermore, the fixed position of the fixed guide seat on the horizontal base satisfies the following conditions: when the movable pallet is in its minimum retracted position, the fixed guide seat is close to the second end; when the movable pallet is in its maximum extended position, the fixed guide seat is close to the first end.

[0017] In the aforementioned automatic pallet conveying device, the transmission belt on the pallet is mounted on the moving pallet via two synchronous pulleys arranged at intervals relative to each other along the moving direction of the moving pallet; the distance between the synchronous pulleys is adapted to the length of the long strip clearance groove;

[0018] The fixed guide seat is fixedly connected to the transmission belt on the pallet, and the conveying slider is fixedly connected to the transmission belt on the pallet;

[0019] Furthermore, the fixed guide seat and the conveying slider are located on opposite sides of the annular path formed by the transmission belt on the pallet; when the movable pallet is in its minimum retracted position, the fixed guide seat is closer to the second end, and the conveying slider is closer to the first end; when the movable pallet is in its maximum extended position, the fixed guide seat is closer to the first end, and the conveying slider is closer to the second end.

[0020] In the aforementioned automatic pallet conveying device, the first transmission component includes a first driving member, a first transmission belt, and a transmission connecting block;

[0021] The first driving component and the first transmission belt are fixed relative to the horizontal base;

[0022] The transmission connecting block is fixedly connected to the movable pallet and engages with the first transmission belt. The first driving member drives the first transmission belt to move the transmission connecting block, thereby driving the movable pallet to move horizontally relative to the horizontal base.

[0023] In the above-mentioned automatic pallet conveying device, a first horizontal guide rail group is provided on the horizontal base, and the movable pallet slides in cooperation with the first horizontal guide rail group.

[0024] The movable pallet is provided with a second horizontal guide rail group, and the conveying slider is disposed on the second horizontal guide rail group and is driven by the transmission belt on the pallet to slide on the second horizontal guide rail group;

[0025] A reset sensor and / or a positioning sensor are provided on the horizontal base. The reset sensor is used to acquire a reset signal when the movable pallet retracts to the initial position, and the positioning sensor is used to acquire a positioning signal when the movable pallet extends to the target position.

[0026] In the above-mentioned automatic pallet conveying device, the first horizontal guide rail group includes two first horizontal guide rails arranged in parallel with each other, and the bottom of the movable pallet is provided with a first guide groove that slides in cooperation with the two first horizontal guide rails.

[0027] The second horizontal guide rail assembly includes two parallel horizontal guide rails. The transfer slider is slidably mounted on one of the horizontal guide rails, and a driven slider is mounted on the other horizontal guide rail. The transfer slider and the driven slider are used to jointly support the sample tray.

[0028] In the above-mentioned automatic pallet conveying device, both the conveying slider and the driven slider have mounting seats on their tops. The conveying slider and the driven slider are jointly mounted with a pallet support plate for supporting the sample pallet through the mounting seats, so as to jointly support the sample pallet.

[0029] The pallet support plate has a pallet limiting component.

[0030] In the aforementioned automatic pallet conveying device, the pallet limiting member includes at least two protrusions disposed on the upper surface of the pallet support plate;

[0031] The sample tray has at least two slots that are adapted to the protrusion.

[0032] The aforementioned automatic pallet conveying device also includes a longitudinal transmission mechanism, which comprises a longitudinal base, a longitudinal guide rail assembly, a longitudinal transmission component, and a longitudinal slider.

[0033] The longitudinal transmission assembly is used to drive the longitudinal slider to move vertically on the longitudinal guide rail assembly, and the horizontal base is fixedly connected to the longitudinal slider through a base mounting block.

[0034] In the above-mentioned automatic pallet conveying device, the longitudinal transmission component includes a second drive component and a lead screw assembly, wherein the second drive component drives the longitudinal slider to move up and down through the lead screw assembly;

[0035] The longitudinal base has a longitudinal height sensor for detecting the longitudinal height of the horizontal base.

[0036] In the aforementioned automatic pallet conveying device, the sample pallet extends to the outer edge of the pallet support plate in at least two opposite directions;

[0037] Furthermore, the sample tray extends to the two opposite edges of the tray support plate and is provided with several retraction limiting holes;

[0038] The retraction limiting hole is adapted to fit with two rows of upward retraction limiting protrusions on the downstream table surface, and there is a recessed space between the two rows of retraction limiting protrusions extending to the edge of the downstream table surface for accommodating the pallet support plate, or the pallet support plate and the movable tray.

[0039] After the horizontal transmission mechanism conveys the sample tray to the target position, the horizontal base is lowered so that the retraction limit hole aligns with the retraction limit protrusion, and the tray support plate sinks into the sinking space.

[0040] Continue to lower the horizontal base until the protrusion falls off the slot, completing the sample tray transfer. Then, retract the moving tray and the transfer slider.

[0041] The advantages of this invention are as follows: Through a compact structural layout, this invention effectively expands the horizontal conveying distance while ensuring high space utilization. Specifically, the device features a long, narrow clearance groove inside the moving pallet for a fixed guide seat to pass through and be fixedly connected to the transmission belt on the pallet. Simultaneously, a conveying slider is fixed on the opposite side of the transmission belt's circular path. This cleverly integrates the point of action within the moving component. While maintaining the effective stroke of the moving pallet itself, the fixed guide seat acts as the point of action, forcing the transmission belt on the pallet to rotate in a circular motion on the synchronous pulleys at both ends. This allows the conveying slider to achieve a displacement superimposed on the displacement of the moving pallet itself. Therefore, this device achieves a sample tray conveying distance significantly greater than the moving pallet's own stroke within a limited space, effectively resolving the contradiction between limited equipment space and the need for long-distance automatic conveying.

[0042] This invention, through the coordinated operation of a horizontal transmission mechanism and a downstream platform structure, combined with a vertical transmission mechanism, achieves stable placement of the sample tray and retraction of the conveyor slider without the need for additional components, by utilizing lifting actions and the cooperation of this device, the sample tray, and the platform structure. On the basis of realizing automated sample tray handover, it further simplifies the unloading process and improves the integration and ease of operation of the conveying device.

Detailed Implementation

[0053] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0054] like Figures 1-5 As shown, this embodiment provides an automatic tray conveying device for transferring sample trays 06 between upstream and downstream processes, realizing the automatic transfer of sample trays 06 between two instruments or between two processes. The device mainly includes a horizontal transmission mechanism 01, which is set on a horizontal base 02 and is used to transport the sample trays 06 horizontally to a predetermined position on the downstream table 051.

[0055] In particular, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The horizontal transmission mechanism 01 is used to drive the sample tray 06 to be transported in the horizontal direction, and includes a first transmission component 011 and a second transmission component 012.

[0056] A first transmission assembly 011 drives a movable pallet 013 to move relative to a horizontal base 02. The first transmission assembly 011 includes a first driving member 0111, a first transmission belt 0112, and a transmission connecting block 0113. The horizontal base 02 has two synchronous pulleys arranged at horizontal intervals. The first transmission belt 0112 is wound between these two synchronous pulleys and meshes with them. The first driving member 0111 is fixed to one end of the horizontal base 02, and its output shaft is connected to one of the synchronous pulleys, driving the first transmission belt 0112 to perform a horizontal linear circular rotation. The transmission connecting block 0113 is fixedly connected to the movable pallet 013 and to the first transmission belt 0112, such that when the first driving member 0111 drives the first transmission belt 0112 to rotate horizontally, it can drive the transmission connecting block 0113 and the movable pallet 013 to move horizontally relative to the horizontal base 02.

[0057] Furthermore, a first horizontal guide rail assembly 021 is fixedly installed on the horizontal base 02, and a first guide groove is provided at the bottom of the movable pallet 013, the first guide groove slidingly engaging with the first horizontal guide rail assembly 021. Specifically, the first horizontal guide rail assembly 021 includes two parallel first horizontal guide rails, and the number of first guide grooves at the bottom of the movable pallet 013 matches the number of first horizontal guide rails.

[0058] The second transmission assembly 012 is located above the movable pallet 013 and includes a fixed guide seat 0121 fixed to the horizontal base 02, and a pallet transmission belt 0123 and a transmission slider 0122 disposed on the movable pallet 013. The movable pallet 013 has an elongated clearance groove 0131 extending along the moving direction of the movable pallet 013. The fixed guide seat 0121 extends upward from the horizontal base 02, passes through the elongated clearance groove 0131, and protrudes from the upper surface of the movable pallet 013.

[0059] like Figure 1 and Figure 2 As shown, the transmission belt 0123 on the pallet is mounted on the movable pallet 013 via two synchronous pulleys arranged at intervals relative to each other along the moving direction of the movable pallet 013, and extends along the moving direction of the movable pallet 013. The synchronous pulleys and the synchronous belt engage with each other via meshing teeth. The distance between the synchronous pulleys is adapted to the length of the elongated clearance groove 0131. The fixed guide seat 0121 passes through the elongated clearance groove 0131 and is fixedly connected to the transmission belt 0123 on the pallet for transmission engagement with the transmission belt 0123 on the pallet.

[0060] Furthermore, the fixed installation position of the fixed guide seat 0121 on the horizontal base 02 matches the stroke length of the elongated clearance groove 0131 on the movable pallet 013, so that the fixed guide seat 0121 is always located in the elongated clearance groove 0131 throughout the entire movement of the movable pallet 013 from the minimum retracted position to the maximum extended position, and maintains a fixed connection and transmission cooperation with the transmission belt 0123 on the pallet.

[0061] Specifically, the elongated clearance groove 0131 has a first end and a second end, respectively. At maximum stroke, i.e., when the movable pallet 013 is in its maximum extended position, the second end is further away from the horizontal base 02 than the first end. When the movable pallet 013 is in such a position... Figure 4 , Figure 5 When retracted to the minimum retracted position as shown, the fixed guide seat 0121 approaches the second end of the elongated clearance groove 0131; when the moving pallet 013 is as shown... Figure 6 , Figure 7 As shown, when moved to the maximum extended position, the fixed guide seat 0121 approaches the first end of the elongated clearance groove 0131. The relative position change of the fixed guide seat 0121 between the two ends of the elongated clearance groove 0131 matches the sliding stroke range of the transmission belt 0123 on the pallet relative to the movable pallet 013.

[0062] Furthermore, the horizontal base 02 is also equipped with a reset sensor 022 and / or a positioning sensor, both of which are connected to the controller when in use. The acquired signals are provided to the controller so that it can control the controlled components such as the first drive unit 0111 and the second drive unit 0331 as needed. The reset sensor 022 is used to acquire the reset signal when the moving pallet 013 retracts to its initial position, and the positioning sensor is used to acquire the positioning signal when the moving pallet 013 conveys the sample tray 06 to the target position. The specific installation position of the positioning sensor is determined according to requirements and is not limited here. This target position is preferably the downstream process table, referred to here as the downstream table 051. That is, when the device retracts, it is in a state of waiting to receive the sample tray 06; when it extends, it conveys the sample tray to the downstream table. Of course, when in use, it can also be the opposite, that is, receiving the sample tray 06 when extended and sending out the sample tray 06 when retracted. This embodiment will use the former as an example thereafter.

[0063] The aforementioned horizontal transmission mechanism 01 achieves a larger transfer stroke while maintaining a compact structure. The following is a detailed explanation based on its principle. When the first driving component 0111 rotates in the forward direction, it drives the moving pallet 013 to move a distance L along the first horizontal guide rail group 021 towards the downstream equipment.

[0064] Since the fixed guide seat 0121 passes through the elongated clearance groove 0131 and is fixedly connected to the transmission belt 0123 on the pallet, and the fixed guide seat 0121 remains stationary with the horizontal base 02, when the moving pallet 013 moves, the transmission belt 0123 on the pallet moves synchronously with the moving pallet 013. At this time, the transmission belt 0123 on the pallet will have a relative displacement with the stationary fixed guide seat 0121. The stationary fixed guide seat 0121 acts as a fixed point of action and applies a reverse pulling force to the transmission belt 0123 on the pallet. This reverse pulling force forces the transmission belt 0123 on the pallet to make a circular rotation around the synchronous pulley and generate a sliding displacement relative to the moving pallet 013. Meanwhile, since the conveyor slider 0122 is fixedly connected to the transmission belt 0123 on the pallet, the sliding displacement of the transmission belt 0123 on the pallet relative to the moving pallet 013 is transmitted to the conveyor slider 0122, causing the conveyor slider 0122 to generate a relative sliding displacement L' on the second horizontal guide rail assembly 0132 that is in the same direction as the moving pallet 013. Therefore, the actual horizontal displacement of the conveyor slider 0122 relative to the horizontal base 02 is the sum of the absolute displacement L of the moving pallet 013 and the relative displacement L' of the conveyor slider 0122 relative to the moving pallet 013, effectively extending the conveying stroke of the drive mechanism.

[0065] Preferably, the movable pallet 013 is further provided with a second horizontal guide rail group 0132 parallel to the first horizontal guide rail group 021. The second horizontal guide rail group 0132 includes two parallel second horizontal guide rails. The conveying slider 0122 is slidably disposed on one of the second horizontal guide rails and is fixedly connected to the transmission belt 0123 on the pallet to move in conjunction with the transmission belt 0123 on the pallet. A driven slider 0133 is provided on the other second horizontal guide rail.

[0066] Furthermore, both the conveyor slider 0122 and the driven slider 0133 have mounting bases 0134 on their tops. A tray support plate 0135 for supporting the sample tray 06 is jointly mounted on both the conveyor slider 0122 and the driven slider 0133 via the mounting bases 0134, thus jointly supporting the sample tray 06. Figure 5 and Figure 7 As shown.

[0067] Specifically, the pallet support plate 0135 has a pallet limiting member. In this embodiment, the pallet limiting member includes at least two protrusions 0136 respectively disposed at both ends of the upper surface of the pallet support plate 0135, and the two ends of the sample pallet 06 have at least two slots 061 adapted to the protrusions 0136.

[0068] Meanwhile, the device also includes a longitudinal transmission mechanism 03, which is mounted on a longitudinal base 04 and is used to drive the horizontal base 02 and its horizontal transmission mechanism 01 to move up and down in the vertical direction, so as to realize the transfer of sample trays 06 between platforms of different heights.

[0069] like Figure 1 and Figure 3 As shown, the longitudinal transmission mechanism 03 includes a longitudinal guide rail assembly 032, a longitudinal transmission component 033, and a longitudinal slider 034. The longitudinal guide rail assembly 032 is vertically fixed to the longitudinal base 04. The longitudinal transmission component 033 includes a second drive member 0331 and a lead screw assembly 0332. The second drive member 0331 is arranged at the lower end of the longitudinal base 04. The lead screw assembly 0332 is connected to the output shaft of the second drive member 0331 and is arranged along the extension direction of the longitudinal guide rail assembly 032. The longitudinal slider 034 is sleeved on the lead screw nut of the lead screw assembly 0332 and is in sliding engagement with the longitudinal guide rail assembly 032. The second drive member 0331 drives the screw of the lead screw assembly 0332 to rotate, thereby driving the longitudinal slider 034 to move vertically along the longitudinal guide rail assembly 032. The horizontal base 02 is fixedly connected to the longitudinal slider 034 through a base mounting block 031, so that the entire horizontal transmission mechanism can rise and fall with the longitudinal slider 034.

[0070] In addition, a longitudinal height sensor is installed on the longitudinal base 04. This height sensor is also connected to the controller and is used to detect the height position of the longitudinal slider 034, that is, to detect the longitudinal position of the horizontal base 02, and to provide the detection signal to the controller.

[0071] Furthermore, the sample tray 06 extends to the outer edge of the tray support plate 0135 in at least two opposing directions, such as Figure 6 As shown, in this embodiment, the sample tray 06 extends along the line connecting the two sliders 0133 and 0122, beyond the outer edge of the tray support plate 0135, and four retraction limiting holes 062 are provided at this edge, two on each side.

[0072] Correspondingly, such as Figure 9 As shown, there are two rows of two upward-facing retraction limit protrusions 055 at the downstream platform 051, and the retraction limit protrusions 055 are adapted to the retraction limit holes 062.

[0073] Meanwhile, a recessed space 054 extending to the edge of the downstream tabletop 051 exists between the two rows of retraction limiting protrusions 055. Depending on the distance between the upstream and downstream tabletops, the length of the pallet support plate 0135, and the distance of the pallet placement area 052 from the edge of the tabletop, this recessed space 054 is used to accommodate the pallet support plate 0135, or the pallet support plate 0135 and the movable pallet 013. The width, length, and depth of the recessed space 054 can be determined according to requirements and are not specifically limited here.

[0074] This embodiment combines Figures 6-9 This further illustrates the docking action between sample tray 06 and downstream table 051.

[0075] The downstream table 051 is the receiving end of the sample tray 06. In this embodiment, the upstream and downstream processes are performed by two devices. The downstream device 05, where the downstream table 051 is located, has a docking opening 053 on its side wall for the horizontal transmission mechanism of the conveying device to pass through. The downstream table 051 has a tray placement area 052, where the retraction limiting protrusion 055 and the sinking space 054 are located.

[0076] After the horizontal transmission mechanism 01 transmits the sample tray 06 to the target position, the controller lowers the horizontal base 02 so that the retraction limit hole 062 aligns with the retraction limit protrusion 055. At this time, the sample tray 06 is placed stably on the tray placement area 052.

[0077] Continue lowering the horizontal base 02. At this point, the sample tray 06 is locked by the retraction limit protrusion 055 and stopped by the platform where the retraction limit protrusion 055 is located, preventing further descent. Meanwhile, the tray support plate 0135 continues to sink in the sinking space 054. As a result, the protrusion 0136 of the tray support plate 0135 disengages from the slot 061 of the sample tray 06. The moving pallet 013 and the conveying slider 0122, located within the sinking space 054, retract along the edge of the platform, leaving the sample tray 06 in the tray placement area 052, thus completing the automated transfer of the sample tray 06. The width and length of the sinking space 054 are adapted to the external dimensions of the moving pallet 013 and the tray support plate 0135, with a horizontal retraction clearance. The depth of the sinking space 054 is not less than the vertical displacement required for the protrusion 0136 to completely disengage from the slot 061.

[0078] It should be noted that the structure of this solution is not only applicable to the transfer of centrifuge tube trays in cytogenetics testing processes, but also to the transfer of trays used to carry samples or reagents in other fields and processes.

[0079] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
