[0046] The present application provides a sample rack transport device, which includes: a frame 100, a hooking mechanism 200 and a pushing mechanism 300. The hooking mechanism 200 is arranged on the frame 100 and slidably cooperates with the frame 100. The hooking mechanism 200 is used to hook the sample rack 500 out of the storage bin 600 or send the sample rack 500 into the storage bin 600; the pushing mechanism 300 is arranged on the frame 100, and is used to push the sample rack 500 to move in a direction away from the storage bin 600 when the sample rack 500 is moved out of the storage bin 600, wherein the hooking direction of the hooking mechanism 200 and the pushing direction of the pushing mechanism 300 are arranged at an angle.

[0047] The sample rack transfer device is provided with a hooking mechanism 200 and a pushing mechanism 300 installed on the rack 100. When the sample rack 500 needs to be moved out of the storage bin 600, the hooking mechanism 200 hooks the sample rack 500 in the storage bin 600, thereby moving the sample rack 500 out of the storage bin 600, and then the pushing mechanism 300 pushes the sample rack 500, thereby moving the sample rack 500 away from the rack 100, and thus away from the storage bin 600. When the sample rack 500 needs to be sent into the storage bin 600, the hooking mechanism 200 hooks the sample rack 500, and then the hooking mechanism 200 drives the sample rack 500 to move, thereby sending the sample rack 500 into the storage bin 600. Moreover, in actual operation, by limiting the installation position of the sample rack transfer device, the hooking direction of the hooking mechanism 200 and the pushing direction of the pushing mechanism 300 can be predicted, thereby facilitating the transfer of the sample rack 500 to a preset position. The sample rack transport device of the present application occupies a small space and has high maintainability, and is suitable for transporting sample racks 500 in areas with limited space.

[0048] It should be noted that the hooking direction of the hooking mechanism 200 and the pushing direction of the pushing mechanism 300 are arranged at an angle. In some embodiments, the angle between the hooking direction and the pushing direction is an acute angle, in some embodiments, the angle between the hooking direction and the pushing direction is an obtuse angle, and in this embodiment, the angle between the hooking direction and the pushing direction is a right angle, that is, the angle between the hooking direction and the pushing direction is 90°.

[0049] Specifically, Figure 1As shown, a slot 510 is provided on the sample rack 500 , and the hooking mechanism 200 can partially extend into the slot 510 , thereby hooking the sample rack 500 .

[0050] Specifically, Figure 1 As shown, the sample rack transport device also includes a fixed base 700 , and the rack 100 and the storage bin 600 are both disposed on the fixed base 700 .

[0051] Specifically, Figures 2 to 4 As shown, the frame 100 has a first mounting platform 110 and a second mounting platform 120 , a pushing mechanism 300 is mounted on the first mounting platform 110 , and a hooking mechanism 200 is mounted on the second mounting platform 120 .

[0052] More specifically, if Figures 2 to 4 As shown, there is a height difference between the first mounting platform 110 and the second mounting platform 120, and the dimension between the first mounting platform 110 and the fixed base 700 along the first direction is greater than the dimension between the second mounting platform 120 and the fixed base 700 along the first direction, wherein the first direction is the height direction of the fixed base 700. Figure 2 From a viewing angle, the first mounting platform 110 is higher than the second mounting platform 120 .

[0053] Further, in order to use the pushing mechanism 300 to push the sample rack 500, as shown in FIG. Figures 3 to 8 As shown, the pushing mechanism 300 includes a pushing drive unit 310 and a pushing unit 320. The pushing unit 320 includes a primary transmission assembly 321 and a push plate 322. The primary transmission assembly 321 is a synchronous belt assembly. The pushing drive unit 310 is connected to the synchronous belt assembly to drive the synchronous belt assembly to operate. The movement direction of the primary belt 3213 in the synchronous belt assembly is parallel to the pushing direction. The push plate 322 is connected to the primary belt 3213. By connecting the push plate 322 to the primary belt 3213 of the synchronous belt assembly, when the pushing drive unit 310 drives the primary belt 3213 of the synchronous belt assembly to move along the pushing direction, the push plate 322 is driven to move along the pushing direction.

[0054] Specifically, the primary transmission assembly 321 includes a primary transmission assembly 321 and a push plate 322. The primary transmission assembly 321 includes a primary first pulley 3211, a primary second pulley 3212, and a primary belt 3213 connected to the primary first pulley 3211 and the primary second pulley 3212. The primary first pulley 3211 and the primary second pulley 3212 are both rotatably connected to the frame 100, and one of them is connected to the output end of the push drive unit 310. When the push drive unit 310 drives one of the primary first pulley 3211 and the primary second pulley 3212 to rotate, the primary belt 3213 starts to move in the pushing direction, thereby driving the push plate 322 to move in the pushing direction, and then pushing the sample rack 500.

[0055] Specifically, Figures 3 to 8 As shown, in this embodiment, the push drive unit 310 is connected to the primary first pulley 3211 , and the primary second pulley 3212 is rotatably connected to the first mounting platform 110 .

[0056] In other embodiments, the push drive unit 310 is connected to the first-stage second pulley 3212 , and the first-stage first pulley 3211 is rotatably connected to the first mounting platform 110 .

[0057] Specifically, Figures 3 to 8 As shown, the primary transmission assembly 321 further includes a primary slide rail 3214 and a primary slider 3215 that are slidably matched, the primary slide rail 3214 extends along the pushing direction, the primary slide rail 3214 is installed on the frame 100, and the primary belt 3213 is connected to the push plate 322 through the primary slider 3215. By providing the primary slide rail 3214 and the primary slider 3215, the primary belt 3213 is connected to the push plate 322 through the primary slider 3215, and when the primary belt 3213 moves along the pushing direction, the primary slider 3215 and the push plate 322 can be driven to move along the pushing direction, and because the primary slider 3215 and the primary slide rail 3214 are slidably matched, the moving direction of the push plate 322 is further limited.

[0058] Specifically, Figures 3 to 8 As shown, the primary transmission assembly 321 includes a first connecting plate 3216 , and the primary slider 3215 is connected to the primary belt 3213 via the first connecting plate 3216 .

[0059] Furthermore, in order to increase the stroke of the push plate 322, as Figures 3 to 8As shown, the pushing unit 320 also includes a secondary transmission assembly 323, the push plate 322 is connected to the secondary transmission assembly 323, the primary belt 3213 is connected to the secondary transmission assembly 323, and the secondary transmission assembly 323 can drive the push plate 322 to move along the pushing direction. By setting the secondary transmission assembly 323, the primary slider 3215 is connected to the push plate 322 through the secondary transmission assembly 323, that is, the primary transmission assembly 321 drives the push plate 322 to move the first preset distance, and the secondary transmission assembly 323 can continue to drive the push plate 322 to move the second preset distance, thereby increasing the stroke of the push plate 322.

[0060] Specifically, Figures 3 to 8 As shown, the secondary transmission assembly 323 includes a transmission plate 3231, a secondary first pulley 3232, a secondary second pulley 3233, and a secondary belt 3234 connected to the secondary first pulley 3232 and the secondary second pulley 3233, the transmission plate 3231 is connected to the primary belt 3213, the secondary first pulley 3232 and the secondary second pulley 3233 are both rotatably connected to the transmission plate 3231, the movement direction of the secondary belt 3234 is parallel to the pushing direction, the secondary belt 3234 includes a first belt portion and a second belt portion arranged along a first direction, wherein the first direction is perpendicular to the pushing direction, the first belt portion is connected to the frame 100, and the second belt portion is connected to the push plate 322. The transmission plate 3231 is connected to the primary belt 3213, that is, the transmission plate 3231 is connected to the primary slider 3215, and the primary slider 3215 moves to drive various parts on the transmission plate 3231 to move along the pushing direction. The first belt portion of the secondary belt 3234 is connected to the frame 100, and the second belt portion is connected to the push plate 322. When the first slider 3215 drives the parts on the transmission plate 3231 to move, the second first pulley 3232 and the second second pulley 3233 are rotated, and the second belt portion moves in the pushing direction, thereby driving the push plate 322 to move in the pushing direction, thereby completing the secondary stroke doubling operation.

[0061] It should be noted that the first direction is the height direction of the rack 100 or the fixed base 700 .

[0062] Specifically, Figures 3 to 8 As shown, the secondary transmission assembly 323 includes a secondary slide rail 3235 and a secondary slider 3236 that are slidably matched. The secondary slide rail 3235 is installed on the transmission plate 3231 and extends along the pushing direction. The secondary belt 3234 is connected to the push plate 322 through the secondary slider 3236. By providing the secondary slide rail 3235 and the secondary slider 3236, the secondary slider 3236 is connected to the push plate 322, and the moving direction of the push plate 322 when doubling the stroke is further limited.

[0063] Specifically, Figures 3 to 8As shown, the secondary transmission assembly 323 includes a second connecting plate 3237 and a third connecting plate 3238, the second belt portion of the secondary belt 3234 is connected to the secondary slider 3236 through the second connecting plate 3237, and the first belt portion of the secondary belt 3234 is connected to the frame 100 through the third connecting plate 3238.

[0064] In summary, the push unit 320 of the present application includes a primary transmission assembly 321, a secondary transmission assembly 323, and a push plate 322. The primary transmission assembly 321 drives the secondary transmission assembly 323 and the push plate 322 to move together by a first preset distance, and the secondary transmission assembly 323 can continue to drive the push plate 322 to move by a second preset distance. In addition, by providing a primary slide rail 3214 and a primary slider 3215, the moving direction of the secondary transmission assembly 323 and the push plate 322 when moving the first preset distance is limited, and by providing a secondary slide rail 3235 and a secondary slider 3236, the moving direction of the push plate 322 when moving the second preset distance is further limited.

[0065] Furthermore, if Figures 3 to 8 As shown, the push drive unit 310 includes a rotating rod 311, and the push unit 320 is provided with two groups. The first-level first pulleys 3211 of the multiple groups of push units 320 are all sleeved on the rotating rod 311, and the rotating rod 311 can synchronously drive the multiple first-level first pulleys 3211 of the multiple groups of push units 320 to rotate. Multiple groups of push units 320 are provided, and the multiple first-level first pulleys 3211 of the multiple groups of push units 320 are all sleeved on the rotating rod 311. The multiple groups of push units 320 are driven by the same rotating rod 311, which reduces the number of driving parts, optimizes the structural arrangement of the push mechanism 300, and reduces the production cost.

[0066] In this embodiment, two groups of pushing units 320 are provided, and the two primary first pulleys 3211 of the two groups of pushing units 320 are both sleeved on the rotating rod 311 and have an interference fit with the rotating rod 311 .

[0067] In other embodiments, the number of the pushing units 320 is determined according to actual operations, and may be one group, three groups, four groups or even more.

[0068] Specifically, Figures 3 to 8 As shown, the push driving unit 310 further includes a push driving member 312 , and an output end of the push driving member 312 is connected to the rotating rod 311 through a synchronous belt structure.

[0069] In other embodiments, the output end of the push driving member 312 may also be directly connected to the rotating rod 311 , as long as the push driving member 312 can drive the rotating rod 311 to rotate.

[0070] Specifically, in this embodiment, Figures 3 to 8As shown, the push plate 322 is bent, and includes a first connection portion, a second connection portion and a third connection portion connected in sequence, and the third connection portion extends in a direction away from the first connection portion, and the first connection portion and the second connection portion, as well as the second connection portion and the third connection portion are vertically arranged.

[0071] In other embodiments, the push plate 322 can be configured in any shape as long as it can push the sample rack 500 to move. For example, the push plate 322 can be in an arc shape.

[0072] Further, in order to hook the sample holder 500, in this embodiment, as Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, the hooking mechanism 200 includes a chain 210 connected end to end, and a hook rod 220 connected to the chain 210, and the chain 210 can circulate to drive the hook rod 220 to move and snap into the sample rack 500. The hook rod 220 is provided on the chain 210, and the chain 210 circulates to drive the hook rod 220 to move, and then the hook rod 220 is hooked into the card slot 510 of the sample rack 500, so as to realize the in and out transportation of the sample rack 500 in the single storage bin 600.

[0073] It should be noted that the chain 210 is connected end to end, that is, the movement path of the chain 210 is a closed loop, and the movement path of the hook rod 220 installed on the chain 210 is also a closed loop. When the chain 210 turns, the hook rod 220 is also driven to turn, so that it can be inserted into the slot 510 of the sample rack 500.

[0074] It should be noted that, in this embodiment, the hooking direction of the hooking mechanism 200 is the movement direction of the hook rod 220. As can be seen from the above, the movement path of the hook rod 220 is a closed loop, so the hooking direction of the hooking mechanism 200 is an arc shape, and the hooking direction naturally has an angle with the pushing direction.

[0075] In other embodiments, the hooking direction of the hooking mechanism 200 is naturally different by setting a different structure of the hooking mechanism 200. For example, in other embodiments, the movement path of the hook rod 220 of the hooking mechanism 200 is a straight line, and the hooking direction of the hooking mechanism 200 is a straight line.

[0076] Specifically, in this embodiment, Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, the hooking mechanism 200 includes a hooking driving member 230 , the output end of the hooking driving member 230 is connected to the chain 210 through a synchronous belt structure, and the hooking driving member 230 drives the chain 210 to perform a cyclic motion.

[0077] Furthermore, if Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, in order to enable the hook mechanism 200 to move to the vicinity of the storage bin 600 to transport the sample rack 500, the sample rack transport device further includes a moving mechanism 400, the hook mechanism 200 is connected to the frame 100 through the moving mechanism 400, the moving mechanism 400 is slidably matched with the frame 100, and the moving mechanism 400 can drive the hook mechanism 200 to move, so that the hook mechanism 200 and the storage bin 600 are arranged at intervals along the second direction, wherein the second direction is the length direction of the chain 210. By providing the moving mechanism 400, the moving mechanism 400 is installed on the frame 100, the hook mechanism 200 is connected to the moving mechanism 400, and the moving mechanism 400 moves, thereby driving the hook mechanism 200 to move, and then the hook mechanism 200 and the storage bin 600 are arranged at intervals along the second direction, and at this time, it is convenient to take out or store the sample rack 500.

[0078] Specifically, the first direction, the second direction and the pushing direction are perpendicular to each other.

[0079] Specifically, the hooking mechanism 200 and the moving mechanism 400 slide with each other via a linear guide pair, the hooking mechanism 200 is fixed on a slider of the guide pair, and the guide rail of the guide pair is fixed on the moving mechanism 400.

[0080] Specifically, Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, the motion mechanism 400 includes: a support plate 410 and a meshing rack 420 and a cam 430, the support plate 410 is connected to the hooking mechanism 200, the support plate 410 is slidably matched with the frame 100, and the support plate 410 has a support portion for carrying the sample rack 500; the rack 420 is connected to the support plate 410, and the rack 420 extends along the second direction, and the cam 430 can rotate to drive the rack 420, the support plate 410, and the hooking mechanism 200 to move along the second direction. By rotating the cam 430, because the cam 430 and the rack 420 are meshed, the rack 420 is driven to move along the second direction, and then the support plate 410 connected to the rack 420 and the hooking mechanism 200 are synchronously moved along the second direction, and the relative position between the hooking mechanism 200 and the storage bin 600 is adjusted. When the sample rack 500 needs to be stored or taken out. The supporting portion of the supporting plate 410 is used to support the sample rack 500 to be taken out or stored.

[0081] It should be noted that the pushing mechanism 300 will push the sample rack 500 on the supporting portion of the supporting plate 410 along the pushing direction only after the sample rack 500 is taken out of the storage bin 600. When the sample rack 500 is stored in the storage bin 600, the pushing mechanism 300 will not push the sample rack 500 on the supporting portion of the supporting plate 410.

[0083] Specifically, Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, the motion mechanism 400 includes a translation driving member 480 , the output end of which is connected to the cam 430 .

The first limiting plate 240 and the second limiting plate 440 are respectively arranged on both sides of the support plate 410 along the pushing direction to limit the sample rack 500 carried on the support plate 410. By setting the first limiting plate 240 and the second limiting plate 440, the sample rack 500 on the supporting part of the support plate 410 is limited to prevent the sample rack 500 from deviating from the support plate 410 and affecting the subsequent storage or removal work.

[0086] More specifically, if Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, the second limiting plate 440 is provided with a limiting groove 450 extending in the second direction, the cam 430 is provided with a limiting column 460, and the limiting column 460 partially extends into the limiting groove 450, and the cam 430 can rotate to make the limiting column 460 slide along the limiting groove 450, so that the second limiting plate 440 moves in the first direction. During the rotation of the cam 430, not only the rack 420 and the support plate 410 can be driven to move in the second direction, but also the second limiting plate 440 can be driven to move in the first direction, so that the first limiting plate 240 and the second limiting plate 440 are respectively arranged on both sides of the support plate 410 along the pushing direction, and in the process of carrying the sample rack 500 in and out of the single storage bin 600, the sample rack 500 is limited and guided in the direction of entering and leaving the bin.

[0087] More specifically, if Figure 2 , Figure 3 as well as Fig. 9 and Fig.10 As shown, a limiting slider is set on the second limiting plate 440, and a limiting slider is set on the second mounting platform 120 of the rack 100. The limiting slide rail 470 and the limiting slider are slidably matched, and the limiting slide rail 470 extends along the first direction, thereby further limiting the movement direction of the second limiting plate 440.
