Description

Technical Field

[0002] The sample rack transport device is used to transport samples and needs to achieve movement in three directions: X-axis, Y-axis and Z-axis.

[0003] At present, most of the sample rack transport devices on the market realize movement in three directions by stacking, that is, the X-axis movement is placed at the bottom, the Y-axis movement is stacked on top, and the Z-axis movement is stacked on the Y-axis movement, layer by layer, that is, when the X-axis moves, the Y-axis and the Z-axis will move with it, and when the Y-axis moves alone, the Z-axis will also move with it. This will cause the Z-axis motor to move with it when the Y-axis moves. The stacking structure of the existing sample rack transport device will take up a large space, and the replacement of parts is also more troublesome; and because the Y-axis and the Z-axis will move with the Z-axis, and the Z-axis will move with the Y-axis, the cable routing of each component is very messy; in addition, in the existing sample rack transport device, linear bearings are mostly used to achieve guidance in all directions, but linear bearings are prone to failure, resulting in equipment failure.

[0066] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0067] The sample analyzer of the present invention comprises a housing (not shown) and a sample rack transporting device, wherein the sample rack transporting device is used to transport the sample rack and is disposed in the housing. The sample rack transporting devices of the following embodiments can all be applied to the sample analyzer.

[0068] It should be noted that in the following embodiments, X, Y, and Z respectively represent three directions in a Cartesian coordinate system, and the coordinate system can be either a rectangular coordinate system or an oblique coordinate system. Usually, in the sample rack transport device, the three directions X, Y, and Z are perpendicular to each other. The X direction can be called the longitudinal direction, the Y direction can be called the lateral direction, and the Z direction can be called the vertical direction. Of course, in the actual implementation process, the situation where X, Y, and Z correspond to the three directions in the oblique coordinate system is not excluded.

[0069] In some embodiments, in conjunction with Figure 1 , Figure 2 The sample rack transport device includes a base 100, a first carrier 210, an X-axis driving assembly 300, a transport power output assembly 600, a Y-axis driving assembly 400 and a Z-axis driving assembly 500. The first carrier 210 is movably arranged on the base 100. The X-axis driving assembly 300 is used to drive the first carrier 210 to move along the X-axis relative to the base 100; the transport power output assembly 600 is used to drive the sample rack C to move in the XY plane; the Y-axis driving assembly 400 is used to drive the transport power output assembly 600 to move along the Y-axis; and the Z-axis driving assembly 500 is used to drive the sample rack C to move along the Y-axis. The driving component 500 is used to drive the transporting power output component 600 to move along the Z direction; wherein, the trajectory of the transporting power output component 600 along the Y direction is the first trajectory, the Y-direction driving component 400 and the Z-direction driving component 500 are both arranged on the first carrier 210, the transporting power output component 600 is respectively connected to the Y-direction driving component 400 and the Z-direction driving component 500, and the Y-direction driving component 400 is distributed on one side of the first trajectory, and the Z-direction driving component 500 is distributed on the other side of the first trajectory.

[0070] In this way, the Y-axis drive assembly 400 and the Z-axis drive assembly 500 are distributed on both sides of the Y-axis track of the sample rack C, avoiding the stacking of the Z-axis drive assembly 500 and the Y-axis drive assembly 400, reducing the weight of the power element providing power in the drive assembly, which is beneficial to increasing the life of the power element and occupying a smaller height space. The replacement of parts in the Z-axis drive assembly and the replacement of parts in the Y-axis drive assembly 400 do not affect each other, which is beneficial to improving the convenience of parts replacement; in addition, the wiring between the Y-axis assembly and the Z-axis assembly does not interfere with each other, which is beneficial to reducing the degree of wiring clutter.

[0071] In some embodiments, in conjunction with Figure 1 , Figure 3 , Figure 5 , Figure 6 The Z-axis driving assembly 500 includes a Y-axis guide rail 530, a first motor 510 and a first transmission structure 520. The first motor 510 is arranged on the first carrier 210. The first transmission structure 520 is used to convert the power output by the first motor 510 into power for the Y-axis guide rail 530 to move along the Z-axis; the transport power assembly includes an actuator 610 and a Y-axis power input member 620. The actuator 610 is movably arranged on the Y-axis guide rail 530 and rises and falls along the Z-axis with the Y-axis guide rail 530. The actuator 610 docks with or detaches from the sample rack C by rising and falling along the Z-axis. The Y-axis power input member 620 is transmission-connected to the Y-axis driving assembly 400. The actuator 610 and the Y-axis power input member 620 are slidingly connected via the Z-axis guide structure, so that the actuator 610 can move along the Y-axis guide rail 530 under the drive of the Y-axis driving assembly 400.

[0072] This structure can make the power of the Y-direction drive assembly 400 and the Z-direction drive assembly 500 be transmitted to the actuator 610, and the actuator 610 arranged on the Y-direction guide rail 530 is equivalent to being arranged on the Z-direction drive assembly 500. Since the Y-direction drive assembly 400 and the Z-direction drive assembly 500 can move along the X-direction with the first carrier 210, the power of the X-direction drive assembly 300 can also be transmitted to the actuator 610, so that the actuator 610 can move along the X-direction, the Y-direction, and the Z-direction. After the sample rack C is docked with the actuator 610 along the Z-direction, it can move in the XY plane under the drive of the actuator 610. In this structure, the Y-direction guide rail 530 only needs to be transported in a small gap space. Compared with the method of carrying a motor and other accessories to move in the Y or Z direction, this structure saves space to a greater extent.

[0073] It should be noted that this structure enables the sample rack C to move in both the Y and Z directions simultaneously under the drive of the actuator 610, thereby improving work efficiency; and can also control the connector 611 to move in sequence in the Y and Z directions according to actual needs.

[0074] In some embodiments, see Figure 1 The sample rack transport device further includes a second carrier plate 220 for carrying the transported sample rack C, the first carrier 210 is also in a plate shape, the second carrier plate 220 is supported above the first carrier plate, and the Y-axis driving assembly 400 and the Z-axis driving assembly 500 are both disposed between the first carrier plate and the second carrier plate 220. It should be noted that Figure 1 The first carrier 210 is in a plate shape. In actual implementation, the first carrier may also be in other shapes, and the specific shape may be adjusted according to the structures of components such as the Y-axis driving component and the Z-axis driving component.

[0075] For easier understanding, see Figure 8 In an exemplary sample analyzer, a sample rack storage unit A is further provided, and a plurality of sample racks C are arranged on the sample rack storage unit A along the X direction. The sample rack transport device is used to transport the sample on the sample rack storage unit A to the target position B (also referred to as sample injection), or to return the sample rack storage unit A at the target position B to the sample rack storage unit A (also referred to as sample withdrawal). Taking the sample injection process as an example, in combination with reference to Figure 1 When injecting a sample, the first carrier 210 is first driven by the X-direction driving assembly 300 to move along the X-direction to the sample rack C to be transported, and the Z-direction driving assembly 500 drives the transport power output assembly 600 to move along the Z-direction to dock with the sample rack C and pick up the sample rack, and then the Y-direction driving assembly 400 drives the transport power output assembly 600 to move along the Y-direction, that is, drives the sample rack C to move along the Y-direction, so that the sample rack C enters the second carrier; then, the first carrier 210 is transported to the target position B along the X-direction by the X-direction driving assembly 300, and the sample rack C on the second carrier is also moved to the target position B; after the first carrier 210 reaches the target position B, the Y-direction driving assembly 400 drives the transport power output assembly to move along the Y-direction again, so that the sample rack C reaches the target position B, and finally the Z-direction driving assembly 500 is controlled to drive the transport power output assembly 600 to separate from the sample rack C along the Z-direction. In this example, the purpose is to realize the transportation of sample rack C between sample rack storage unit A and target position B. In actual application, the sample rack transportation device in the above and following embodiments can also be used to realize the sample loading and unloading of sample rack C corresponding to workstations such as emergency or TLA channels.

[0076] In some embodiments, in conjunction with Figures 4 to 6The actuator 610 includes a connector 611 and a Z-direction power input slider 612. The connector 611 has a connector structure for cooperating with the sample rack C; the Z-direction power input slider 612 is movably arranged on the Y-direction guide rail 530; the connector 611 is integrally connected with the Z-direction power input slider 612, so that the connector 611 and the Z-direction power input slider 612 move synchronously, and the connector 611 and the Y-direction power input member 620 are connected via the Z-direction guide structure.

[0077] For example, in some embodiments, see Figures 4 to 6 The connector 611 is a push rod, which extends along the Z direction. The push rod passes through the Y-direction power input member 620 , and a linear bearing is provided between the push rod and the Y-direction power input member 620 . Figure 4 In the embodiment, the Z-direction power input slider 612 is disposed below the Y-direction power input member 620 . In actual implementation, the Z-direction power input slider 612 may also be disposed below the Y-direction power input member 620 .

[0078] In some embodiments, see Figure 1 , Figure 7 The second carrier plate 220 is provided with an avoidance through-hole 221 for avoiding the actuator 610, and the long side direction of the avoidance through-hole 221 extends along the Y direction. The plug-in structure is provided on the actuator 610 so that the actuator 610 can pass through the avoidance through-hole and be plugged with the sample rack C on the second carrier plate 220 under the drive of the Z-direction driving component 500.

[0079] In one example, see Figures 3 to 6 , connector 611 is a push rod, see Figure 7 The bottom of the sample rack C is provided with a plug hole C1 for inserting the push rod, and the avoidance slot 221 is to avoid the push rod so that the push rod can be smoothly inserted into the plug hole at the bottom of the sample rack C. In the actual implementation process, the plug-in method between the actuator 610 and the sample rack is not necessarily the shaft-hole matching method, and can also be other structures as long as the plug-in can be achieved.

[0080] In some embodiments, see Figure 6 The first carrier 210 is also provided with a Z-direction guide rail 800, and the Z-direction driving assembly 500 is used to drive the Y-direction guide rail 530 to move along the Z-direction guide rail 800. Figure 1In some embodiments, the base 100 is also provided with an X-direction guide rail 700, and the X-direction driving assembly 300 is used to drive the first carrier 210 to move along the X-direction guide rail 700. At this time, the movement in the three directions of X, Y, and Z is guided by the X-direction guide rail 700, the Y-direction guide rail 530, and the Z-direction guide rail 800, respectively. Compared with the method of using linear bearings in the existing sample rack transport device, this method is conducive to reducing the failure rate and has higher precision.

[0081] In some embodiments, see Figure 5 , Figure 6 The first transmission structure 520 includes a first driving wheel 521, a first driven wheel 522, a first transmission member and a lifting assembly 524, wherein the first driving wheel 521 is connected to the first motor 510, and the axis of the first driving wheel 521 is parallel to the XY plane; the first driven wheel 522 is arranged on the first bearing member 210, and the first driven wheel 522 rotates with the first driving wheel 521; the first transmission member is tensioned on the first driving wheel 521 and the first driven wheel 522, and the first transmission member is a transmission belt or a transmission chain; the lifting assembly 524 is arranged on the first transmission member and is lifted and lowered under the drive of the first transmission member; wherein the first transmission member has a first traction section 523 extending along the Z direction, the lifting assembly 524 is arranged on the first traction section 523, and the Y-direction guide rail 530 is arranged on the lifting assembly 524.

[0082] When the sample rack C needs to move in the Z direction, the driving power of the first motor 510 is first transmitted to the first transmission belt through the first driving wheel 521 and the first driven wheel 522, so that the lifting assembly 524 and the Y guide rail 530 are lifted and lowered accordingly, thereby causing the actuator 610 set on the Y guide rail 530 to lift and lower accordingly, thereby realizing the Z-direction movement of the actuator 610.

[0083] In some embodiments, see Figure 4 The Y-axis driving component 400 includes a second motor 410 and a second transmission structure, wherein the second motor 410 is arranged on the first carrier 210, and the second transmission structure includes a second driving wheel 421, at least one second driven wheel 422, and a second transmission member 423; the second driving wheel 421 is connected to the second motor 410; each of the driven wheels rotates with the second driving wheel 421; the second transmission member 423 is tensioned on the second driving wheel 421 and each of the second driven wheels 422, and the second transmission member 423 is a transmission belt or a transmission chain; wherein the second transmission member 423 has a second traction section 423 parallel to the Y-guide rail 530, and the Y-axis power input member 620 is arranged on the second traction section 423.

[0084] When the sample rack C needs to move along the Y direction, the driving power of the second motor 410 is first transmitted to the second transmission member through the second driving wheel 421 and the second driven wheel 422, so that the Y-direction power input member arranged on the second traction section 423 of the second transmission member moves along the Y direction, driving the Y-direction movement of the actuator 610.

[0085] In some embodiments, see Figures 1 to 3 The X-direction driving assembly also adopts the method of using a driving wheel, a driven wheel and a transmission member, so that the first bearing member can move along the X-guide rail with the Z-direction driving assembly and the Y-direction driving assembly.

[0086] In some embodiments, in conjunction with Figures 4 to 7 The Y-direction power input member 620 includes a guide block 621 and a connecting portion 622 arranged on the outer wall of the guide block 621 , the guide block 621 is provided with a through hole for the push rod to pass through, and the connecting portion 622 is connected to the corresponding second traction section 423 .

[0087] In some embodiments, see Figures 4 to 6 The lifting assembly 524 includes a Z-direction sliding member 523a and a connecting member 523b, the Z-direction sliding member 523a is integrally arranged on one side of the Y-direction guide rail 530; the connecting member 523b connects the first traction section 523 and the Z-direction sliding member 523a; the first motor 510 is arranged next to the Z-direction sliding member 523a, the axis line of the first driving wheel 521 is parallel to the Y-direction guide rail 530, the Z-direction sliding member 523a, the first motor 510 and the connecting member 523b form a accommodating space, the accommodating space is distributed along the Y direction and is adjacent to the first electrode, the Z-direction guide rail 800, the first driving wheel 521, the first driven wheel 522 and the first conveying member are all located in the accommodating space.

[0088] When the sample rack C enters or leaves the sample rack transport device along the Y direction, the size of the sample rack transport device along the Y direction will be determined according to the Y-direction distance between the previous unit and the next unit where the sample rack C is located. Such an arrangement of the Z-direction drive assembly 500 is conducive to making the size of the Z-direction drive assembly 500 in the X direction relatively small, which is also conducive to controlling the size of the entire sample rack C in the X direction and reducing the space occupied by the entire sample rack transport device.

[0089] In some embodiments, see Figure 4 , Figure 5, along the Z direction, the second conveyor belt is located above the Y-direction guide rail 530, and accordingly, at this time, the Z-direction power input slider 612 is arranged below the Y-direction power input member 620. In the actual implementation process, along the Z direction, the second conveyor belt can also be located below the Y-direction guide rail 530, and accordingly, the Z-direction power input slider 612 is also arranged below the Y-direction power input member 620.

[0090] In some embodiments, see Figure 4 , the position of the second driving wheel 421 corresponds to the middle position of the second traction section 423. In the actual implementation process, the position of the second driving wheel 421 can also correspond to one end of the second traction section 423. Figure 4 In the embodiment, the position of the second driving wheel 421 is in the middle of the second traction section 423, which is more conducive to increasing the stroke of the Y-direction power input member 620 in the Y direction, that is, the length of the entire second traction section 423 is longer.

[0091] In some embodiments, see Figure 4 Four second driven wheels 422 are arranged in the second transmission structure of the Y-axis driving assembly 400, two of which are distributed along the Y-axis and tensioned at both ends of the conveyor belt, and the other two second driven wheels 422 are arranged between the two second driven wheels 422 and the second driving wheel in a one-to-one correspondence.

[0092] For easier understanding, see Figure 4 The second transmission member includes an upper section and a lower section distributed along the Z direction, the upper section is the second traction section 423, and the second driving wheel 421 is tensioned on the lower section.

[0093] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
