[0002] In biological science, especially in the field of biochemistry and molecular biology research, it has been widely used. Each biochemistry and molecular biology laboratory must prepare various types of centrifuges. When in use, the centrifuge tube can be set on the centrifuge, and the centrifuge is used to centrifuge and prepare the solution in the centrifuge tube. The solution is suspended in the centrifuge tube. Under the high-speed rotation of the centrifuge tube, due to the huge centrifugal force, the tiny particles suspended in the solution settle at a certain speed, thereby separating from the solution. The centrifuge tubes used in the laboratory analysis process are mostly standard styles, mainly cylindrical tube bodies and centrifuge tube caps that match the tube body. During centrifugation, the material to be centrifuged is loaded into the centrifuge tube, covered with the centrifuge tube cap, and placed in the centrifuge equipment for centrifugal operation, thereby achieving the material separation process.

[0033] See also Figure 1 , which is a schematic structural diagram of a centrifuge tube flipping device according to an embodiment of the present disclosure.

[0034] The centrifuge tube flipping device 300 of one embodiment includes a chassis 310, a conveying assembly 320 and a centrifuge tube flipping assembly 330. The conveying assembly 320 includes a centrifuge tube arrangement conveyor belt 322 and a centrifuge tube flipping conveyor belt 324, both of which are arranged on the chassis 310. The centrifuge tube arrangement conveyor belt 322 is used to convey centrifuge tubes arranged in phase, and the centrifuge tube flipping conveyor belt 324 is used to convey centrifuge tubes arranged in staggered phases. The centrifuge tube flip assembly 330 includes a gantry 332, a flip slide 334, and a flip grabber 336. The gantry 332 is disposed on the chassis 310, and the gantry 332 spans the centrifuge tube arrangement conveyor belt 322 and the centrifuge tube flip conveyor belt 324. The flip slide 334 is connected to the gantry 332, and the flip grabber 336 is slidably connected to the flip slide 334, so that the flip grabber 336 moves between the centrifuge tube arrangement conveyor belt 322 and the centrifuge tube flip conveyor belt 324. The grabbing end of the flip grabber 336 faces the centrifuge tube arrangement conveyor belt 322 and the centrifuge tube flip conveyor belt 324, and the flip grabber 336 is used to grab a plurality of centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 to place them on the centrifuge tube flip conveyor belt 324, and to turn at least some of the centrifuge tubes.

[0035] In this embodiment, after the centrifuge tubes are transferred to the bottom of the gantry 332 through the centrifuge tube arrangement conveyor 322, the flipping grabbing member 336 grabs the centrifuge tubes to the centrifuge tube flipping conveyor 324 in multiple times. During the movement of the flipping grabbing member 336 to grab the centrifuge tubes, the flipping grabbing member 336 turns some of the centrifuge tubes so that the centrifuge tubes on the centrifuge tube flipping conveyor 324 are placed in reverse, so that the centrifuge tube flipping conveyor 324 is loaded with centrifuge tubes with staggered directions, which is convenient for quickly forming a staggered distribution of centrifuge tubes, thereby facilitating the subsequent staggered packaging of the centrifuge tubes.

[0036] In one embodiment, see Figure 2The flipping and grabbing member 336 includes a flipping bracket 3362, a flipping and grabbing motor 3364 and a plurality of flipping and grabbing claws 3366. The flipping bracket 3362 is slidably connected to the flipping slide rail 334. The flipping and grabbing motor 3364 is connected to the flipping bracket 3362. The rotating shaft of the flipping and grabbing motor 3364 is connected to at least one of the flipping and grabbing claws 3366 to rotate the centrifuge tube grabbed by the flipping and grabbing claws 3366. In this embodiment, the flip bracket 3362 moves along the flip rail 334, and the flip bracket 3362 drives the flip grabbing motor 3364 to move on the flip rail 334. Specifically, the slide rail driving screw inside the flip rail 334 pushes the flip bracket 3362 to move, so that the flip grabbing motor 3364 drives the flip grabbing claw 3366 to move back and forth between the centrifuge tube arrangement conveyor belt 322 and the centrifuge tube flip conveyor belt 324, so as to facilitate the grabbing of multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 to the centrifuge tube flip conveyor belt 324. The rotating shaft of the flip grabbing motor 3364 rotates the flip grabbing claw 3366, so that some of the centrifuge tubes grabbed by the flip grabbing claw 3366 are turned, so as to form staggered centrifuge tubes on the centrifuge tube flip conveyor belt 324.

[0037] Furthermore, the flip grabbing member 336 also includes a flip lifting motor 3368 connected to the flip bracket 3362, and the lifting end of the flip lifting motor 3368 is connected to the flip grabbing motor 3364, so that each flip grabbing claw 3366 is away from or close to the chassis 310. In this embodiment, the flip lifting motor 3368 is arranged on the flip bracket 3362, and the flip grabbing motor 3364 is fixed to the flip bracket 3362 through the flip lifting motor 3368. The lifting end of the flip lifting motor 3368 lifts and lowers the flip grabbing motor 3364, thereby driving the flip grabbing claw 3366 to lift and lower, thereby facilitating the flip grabbing claw 3366 to transfer the centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 to the centrifuge tube flip conveyor belt 324.

[0038] In another embodiment, the flip grabbing member 336 further includes a flip transmission driver 3361, which is disposed on the gantry 332, and a driving end of the flip transmission driver 3361 is connected to the flip bracket 3362. In this embodiment, the flip transmission driver 3361 is located at the edge of the gantry 332, and the flip transmission driver 3361 provides guidance and power for the movement of the flip bracket 3362. Specifically, the flip transmission driver 3361 is a chain linear module, which is convenient for driving the flip grabbing claw 3366 to move in a specified direction through the flip bracket 3362.

[0039] In another embodiment, the flip grabbing member 336 also includes a flip connecting plate 3363, which is connected to the rotating shaft of the flip grabbing motor 3364, and the flip connecting plate 3363 is connected to at least one of the flip grabbing claws 3366, and the flip connecting plate 3363 is located between the flip grabbing motor 3364 and the flip grabbing claw 3366. In this embodiment, one side of the flip connecting plate 3363 is connected to the rotating shaft of the flip grabbing motor 3364, and the other side of the flip connecting plate 3363 is connected to each of the flip grabbing claws 3366, that is, the flip grabbing motor 3364 and the flip grabbing claws 3366 are relatively arranged on two sides of the flip connecting plate 3363, and the flip connecting plate 3363 not only serves as a rotating plate driven by the rotating shaft of the flip grabbing motor 3364, but the flip connecting plate 3363 also connects multiple flip grabbing claws 3366 together, so that the flip grabbing motor 3364 can complete the reversal of multiple centrifuge tubes after one rotation, which is convenient for synchronously turning multiple centrifuge tubes to further improve the reverse rotation efficiency of the centrifuge tubes.

[0040] Furthermore, there are multiple flip grabbing motors 3364 and flip connecting plates 3363, and each flip grabbing motor 3364 is connected to a flip connecting plate 3363. In this embodiment, the flip grabbing motors 3364 correspond to the flip connecting plates 3363 one by one, and each flip grabbing motor 3364 rotates one flip connecting plate 3363, so as to simultaneously reverse multiple centrifuge tubes on the flip connecting plates 3363.

[0041] In one embodiment, see Figure 3The flip grabbing member 336 further includes a transport bracket 3365, a transport lifting motor 3367 and a plurality of transport grabbing claws 3369.

The lifting end of the transport lifting motor 3367 is connected to at least one of the transport grabbing claws 3369. In this embodiment, the transport bracket 3365 moves along the extension direction of the flip slide rail 334. The transport bracket 3365 drives the transport lifting motor 3367 to move along the flip slide rail 334. The transport lifting motor 3367 is connected to a plurality of the transport grabbing claws 3369. The transport lifting motor 3367 drives the transport grabbing claws 3369 to lift and lower, so that the transport grabbing claws 3369 can transfer the centrifuge tubes from the centrifuge tube arrangement conveyor belt 322 to the centrifuge tube flip conveyor belt 324.

[0042] Furthermore, in a direction perpendicular to the centrifuge tube turning conveyor 324, the turning grabbing claw 3366 and the transport grabbing claw 3369 are arranged alternately. In this embodiment, the centrifuge tube grabbed by the turning grabbing claw 3366 and the centrifuge tube grabbed by the transport grabbing claw 3369 are arranged in a staggered manner. Specifically, the centrifuge tube grabbed by the turning grabbing claw 3366 and the centrifuge tube grabbed by the transport grabbing claw 3369 are kept in a staggered parallel manner, so that the centrifuge tube grabbed by the transport grabbing claw 3369 is placed on the centrifuge tube turning conveyor 324 in a forward manner, and the centrifuge tube grabbed by the turning grabbing claw 3366 is placed on the centrifuge tube turning conveyor 324 in a reverse manner. On the conveyor belt 324, the centrifuge tubes in the same row or line on the centrifuge tube arrangement conveyor belt 322 are simultaneously grabbed by the transfer grabbing claw 3369 and the flipping grabbing claw 3366, and then the flipping grabbing claw 3366 reverses the centrifuge tubes thereon, so that the transfer grabbing claw 3369 and the flipping grabbing claw 3366 can simultaneously carry two centrifuge tubes in different placement postures to the centrifuge tube flipping conveyor belt 324, thereby realizing staggered placement of multiple centrifuge tubes, so as to improve the efficiency of reversal and transfer of the centrifuge tubes.

[0043] In one embodiment, see Figure 1The centrifuge tube flipping device 300 also includes a centrifuge tube leveling component 340, which includes a leveling bracket 342, a leveling lifting motor 344 and a leveling rod 346.

The leveling rod 346 is provided with a leveling groove 302, and the notch of the leveling groove 302 faces the centrifuge tube arrangement conveyor belt 322. The leveling groove 302 is used to accommodate and squeeze parts of multiple centrifuge tubes to make each of the centrifuge tubes level. In this embodiment, the leveling bracket 342 spans the conveying start end of the centrifuge tube arrangement conveyor belt 322, and the leveling bracket 342 is directly opposite to the loading position of the centrifuge tube arrangement conveyor belt 322. The leveling lifting motor 344 provides power for the movement of the leveling rod 346, so that the leveling rod 346 moves in a direction perpendicular to the centrifuge tube arrangement conveyor belt 322, so that the leveling rod 346 moves away from or approaches the centrifuge tubes on the centrifuge tube arrangement conveyor belt 322. The leveling groove 302 is located on the side of the leveling rod 346 away from the leveling lifting motor 344, and the groove wall of the leveling groove 302 abuts against the centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 to squeeze the centrifuge tubes, so that the multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 remain flush, effectively improving the flatness of the multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322, and facilitating the synchronous grabbing of the multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322.

[0044] Before the actual subpackaging process of the centrifuge tubes, a plurality of centrifuge tubes need to be diverted and transmitted to form a linear distribution. During the linear transmission process, it is very easy to form a blockage on the conveyor belt.

[0045] In order to improve the packing efficiency, the blockage of centrifuge tubes needs to be solved.

[0046] In one embodiment, see Figure 1The centrifuge tube flipping device also includes a centrifuge tube leveling component 340, and the centrifuge tube leveling component 340 includes a leveling bracket 342, a leveling lifting motor 344 and a leveling rod 346.

In this embodiment, the leveling bracket 342 spans the conveying start end of the centrifuge tube arrangement conveyor belt 322, and the leveling bracket 342 is directly opposite to the loading position of the centrifuge tube arrangement conveyor belt 322. The leveling lifting motor 344 provides power for the movement of the leveling rod 346, so that the leveling rod 346 moves in a direction perpendicular to the centrifuge tube arrangement conveyor belt 322, so that the leveling rod 346 moves away from or approaches the centrifuge tubes on the centrifuge tube arrangement conveyor belt 322. The leveling groove 302 is located on the side of the leveling rod 346 away from the leveling lifting motor 344, and the groove wall of the leveling groove 302 abuts against the centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 to squeeze the centrifuge tubes, so that the multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322 remain flush, effectively improving the flatness of the multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322, and facilitating the synchronous grabbing of the multiple centrifuge tubes on the centrifuge tube arrangement conveyor belt 322.

The centrifuge tube is accommodated in the tube slot 602, and the centrifuge tube is limited to avoid the probability of the centrifuge tube falling.

[0050] In another embodiment, the tube delivery push assembly 630 includes a tube delivery slide rail 632 and a tube delivery push member 634. The tube delivery slide rail 632 is disposed on the tube delivery bracket 610.

[0055] In another embodiment, the tube delivery support plate 620 is located between the first tube delivery push rod 6344 and the second tube delivery push rod 6346, so that when one of the push rods pushes the centrifuge tube, the other push rod is prevented from colliding with the tube delivery support plate 620.

[0056] In one embodiment, see Figure 4The centrifuge tube flipping device also includes an anti-blocking mechanism 100, and the anti-blocking mechanism 100 includes a centrifuge tube transmission component 110 and a centrifuge tube anti-blocking component 120. The centrifuge tube transmission component 110 includes a centrifuge tube conveyor belt 112 and a transmission bracket 114, and the centrifuge tube conveyor belt 112 is arranged on the transmission bracket 114, and the centrifuge tube conveyor belt 112 has a transmission channel, and the transmission channel is used to transmit centrifuge tubes. The centrifuge tube anti-blocking component 120 includes a first sliding tube pusher 122 and a second sliding tube pusher 124 that are relatively arranged, and the first sliding tube pusher 122 and the second sliding tube pusher 124 are both movably arranged on the transmission bracket 114, and a tube pusher channel is formed between the first sliding tube pusher 122 and the second sliding tube pusher 124, and the tube pusher channel is connected to the transmission channel. Among them, at least one of the first sliding tube pusher 122 and the second sliding tube pusher 124 is used to push a plurality of centrifuge tubes that are blocked in the tube pusher channel.

[0057] In this embodiment, the centrifuge tubes are transmitted in the transmission channel. When multiple centrifuge tubes are blocked, the first sliding tube pusher 122 and the second sliding tube pusher 124 are both facing the tube pushing channel to push out some of the centrifuge tubes in the tube pushing channel, thereby reducing the number of centrifuge tubes in the tube pushing channel, thereby increasing the distance between the centrifuge tubes in the transmission channel, and further reducing the probability of blockage of the centrifuge tubes in the transmission channel, thereby preventing the transmission of the centrifuge tubes in the transmission channel from being blocked.

[0058] In one embodiment, the push tube channel and the transmission channel at least partially overlap. In this embodiment, the push tube channel and the transmission channel are interconnected, and centrifuge tubes are transmitted in the push tube channel and the transmission channel, and the push tube channel is directly opposite to the first sliding push tube member and the second sliding push tube member. Part of the push tube channel overlaps with the transmission channel, so that the push tube channel and the transmission channel have a common transmission part. When the centrifuge tubes are blocked in the push tube channel or the transmission channel, only part of the centrifuge tubes in the push tube channel need to be pushed out, so that the spacing between the centrifuge tubes on the centrifuge tube conveyor belt can be increased to reduce the blockage of the centrifuge tubes during the transmission process.

[0059] Furthermore, the push tube channel is located in the transmission channel. Specifically, the push tube channel completely overlaps with the transmission channel. At this time, the push tube channel is a part of the transmission channel. When the centrifuge tube passes through the push tube channel, the centrifuge tube is also transmitted in the transmission channel. When the centrifuge tube is blocked, the first sliding push tube member and the second sliding push tube member push out the centrifuge tube in the push tube channel to increase the spacing between the centrifuge tubes at other positions in the transmission channel, so that the probability of blockage of the centrifuge tube is further reduced.

[0060] In one embodiment, see Figure 4 The first sliding tube pushing member 122 includes a first tube pushing cylinder 1222 and a first tube pushing plate 1224. The first tube pushing cylinder 1222 is connected to the transmission bracket 114. The output end of the first tube pushing cylinder 1222 is connected to the first tube pushing plate 1224. The first tube pushing plate 1224 is used to push the centrifuge tube in the tube pushing channel. In this embodiment, the first tube pushing cylinder 1222 is disposed on the transmission bracket 114. Specifically, the first tube pushing cylinder 1222 is located on one side of the centrifuge tube conveyor belt 112. The first tube pushing plate 1224 moves under the drive of the first tube pushing cylinder 1222. When the centrifuge tubes on the centrifuge tube conveyor belt 112 are blocked, the first tube pushing plate 1224 faces the tube pushing channel. For example, the output end of the first tube pushing cylinder 1222 drives the first tube pushing plate 1224 to enter and exit the tube pushing channel, so that the first tube pushing plate 1224 can push some centrifuge tubes away from the centrifuge tube conveyor belt 112 to increase the spacing between the centrifuge tubes in the transmission channel, thereby reducing the probability of blockage.

[0061] For further information, see Figure 5 The second sliding tube pushing member 124 includes a second tube pushing cylinder 1242 and a second tube pushing plate 1244. The second tube pushing cylinder 1242 is connected to the transmission bracket 114. The output end of the second tube pushing cylinder 1242 is connected to the second tube pushing plate 1244. The second tube pushing plate 1244 is arranged opposite to the first tube pushing plate 1224. The tube pushing channel is formed between the second tube pushing plate 1244 and the first tube pushing plate 1224. In this embodiment, the second tube pushing cylinder 1242 is arranged on the transmission bracket 114. Specifically, the second tube pushing cylinder 1242 is located on one side of the centrifuge tube conveyor 112, and the second tube pushing cylinder 1242 is arranged opposite to the first tube pushing cylinder 1222. The second tube pushing plate 1244 moves under the drive of the second tube pushing cylinder 1242. When the centrifuge tubes on the centrifuge tube conveyor belt 112 are blocked, the first tube pushing plate 1224 and the second tube pushing plate 1244 are both facing the tube pushing channel. For example, the output end of the first tube pushing cylinder 1222 drives the first tube pushing plate 1224 to enter and exit the tube pushing channel, and the output end of the second tube pushing cylinder 1242 drives the second tube pushing plate 1244 to enter and exit the tube pushing channel, so that the first tube pushing plate 1224 and the second tube pushing plate 1244 can clamp the centrifuge tubes together, thereby facilitating pushing some centrifuge tubes away from the centrifuge tube conveyor belt 112, so as to increase the spacing between the centrifuge tubes in the transmission channel, thereby further reducing the probability of blockage.

[0062] In another embodiment, the second push tube plate 1244 and the first push tube plate 1224 are respectively flush with the two sides of the transmission channel. Specifically, the space between the second push tube plate 1244 and the first push tube plate 1224 is the push tube channel, and the ends of the second push tube plate 1244 and the first push tube plate 1224 are butted against the ends of the transmission channel, so that the second push tube plate 1244 and the first push tube plate 1224 are embedded in the transmission channel together.

[0063] In one embodiment, see Figure 4 The anti-blocking mechanism 100 further includes a tube blocking recovery conveyor belt 130, which is arranged on the transmission bracket 114, and is located at one side of the transmission channel. The tube blocking recovery conveyor belt 130 is used to transmit the centrifuge tube pushed out of the transmission channel. In this embodiment, the tube blocking recovery conveyor belt 130 is arranged on the side of the centrifuge tube conveyor belt 112, and the tube blocking recovery conveyor belt 130 is opposite to the tube pushing channel, so that the transmission initial end of the tube blocking recovery conveyor belt 130 is facing the tube pushing channel. After the centrifuge tube in the tube pushing channel is pushed out, the centrifuge tube is pushed onto the tube blocking recovery conveyor belt 130, so that the centrifuge tube in the tube pushing channel can be recovered through the tube blocking recovery conveyor belt 130.

[0064] For further information, see Figure 4 The anti-blocking mechanism 100 further includes a recovery lower slide 140, one end of which corresponds to the side of the transmission channel, and the other end of which is located on the blocked tube recovery conveyor belt 130. In this embodiment, the recovery lower slide 140 is located between the centrifuge tube conveyor belt 112 and the blocked tube recovery conveyor belt 130, and the recovery lower slide 140 is tilted. Specifically, the end of the recovery lower slide 140 close to the centrifuge tube conveyor belt 112 is higher than the end of the recovery lower slide 140 close to the blocked tube recovery conveyor belt 130, so as to facilitate the quick dumping of the centrifuge tube pushed out of the tube pushing channel onto the blocked tube recovery conveyor belt 130.

[0065] In one embodiment, see Figure 6The anti-blocking mechanism 100 further includes a dust cover 150, which includes a cover body 152, an anti-blocking observation plate 154, and a handle 156. The cover body 152 is connected to the transmission bracket 114, and the cover body 152 is arranged on the tube pushing channel. The cover body 152 is provided with an observation hole 102, and the anti-blocking observation plate 154 is clamped in the observation hole 102. The handle 156 is connected to a side of the anti-blocking observation plate 154 away from the centrifuge tube conveyor belt 112. In this embodiment, the cover body 152 corresponds to the tube pushing channel, and the cover body 152 covers the area above the tube pushing channel to reduce dust falling into the tube pushing channel. The anti-blocking observation plate 154 is located in the observation hole 102. The anti-blocking observation plate 154 is taken out from the observation hole 102 by the handle 156, so as to observe the transmission situation of the centrifuge tube in the pushing tube channel through the observation hole 102, thereby facilitating determination of whether the centrifuge tube in the pushing tube channel is pushed out when blocked.

[0066] In one embodiment, see Figure 7 The centrifuge tube flipping device further includes a positioning mechanism 200, and the positioning mechanism 200 includes a centrifuge tube transmission component 210 and a loading component 220. The centrifuge tube transmission component 210 includes a base 212, a centrifuge tube conveyor belt 214, and two oppositely arranged transmission baffles 216. The centrifuge tube conveyor belt 214 is arranged on the base 212, and the centrifuge tube conveyor belt 214 is used for linearly conveying centrifuge tubes. The two transmission baffles 216 are arranged on the centrifuge tube conveyor belt 214 to form a single-tube linear conveying trough for conveying centrifuge tubes. The loading component 220 includes a centrifuge tube loading moving part 222 and a centrifuge tube grabbing part 224. The centrifuge tube loading moving part 222 is arranged on the base 212. The moving end of the centrifuge tube loading moving part 222 is connected to the centrifuge tube grabbing part 224. The centrifuge tube grabbing part 224 corresponds to the single-tube linear conveying groove. The centrifuge tube grabbing part 224 is used to grab multiple linearly arranged centrifuge tubes in the single-tube linear conveying groove.

[0067] In this embodiment, multiple centrifuge tubes are moved along the single-tube linear conveying groove driven by the centrifuge tube conveyor belt 214, so that the multiple centrifuge tubes are linearly distributed, and the centrifuge tube grabbing piece 224 is facing the single-tube linear conveying groove, which is convenient for the centrifuge tube grabbing piece 224 to grab multiple linearly distributed centrifuge tubes in the single-tube linear conveying groove at one time, so that the centrifuge tube grabbing piece 224 grabs multiple linearly and evenly distributed centrifuge tubes at the same time, effectively improving the loading efficiency of the centrifuge tubes.

[0068] In one embodiment, see Figure 7, the slot width of the single-tube linear conveying trough is greater than or equal to the width of the centrifuge tube. In this embodiment, the single-tube linear conveying trough is the gap between two oppositely arranged transmission baffles on the centrifuge tube conveyor belt, and the two transmission baffles are arranged in parallel with each other, so that the single-tube linear conveying trough is linear, so that the multiple centrifuge tubes in the single-tube linear conveying trough are distributed in a straight line. The slot width of the single-tube linear conveying trough determines the ease of conveying the centrifuge tube. By setting the slot width of the single-tube linear conveying trough to be greater than or equal to the width of the centrifuge tube, it is convenient to quickly guide the centrifuge tube to between the two oppositely arranged transmission baffles. Moreover, the slot width of the single-tube linear conveying trough is less than the length of the centrifuge tube. Specifically, the slot width of the single-tube linear conveying trough is 1.2 to 1.5 times the width of the centrifuge tube, so that it is convenient to linearly distribute and transmit multiple centrifuge tubes along the single-tube linear conveying trough.

[0069] In one embodiment, see Figure 7 The centrifuge tube loading moving part 222 includes a longitudinal loading bracket 2222, a longitudinal slide rail 2224, a longitudinal slide plate 2226 and a longitudinal motor 2228. The longitudinal loading bracket 2222 is arranged on the base 212, the longitudinal slide rail 2224 is arranged on the longitudinal loading bracket 2222, the longitudinal slide plate 2226 is slidably arranged on the longitudinal slide rail 2224, and the longitudinal slide plate 2226 is also connected to the centrifuge tube grabbing part 224; the longitudinal motor 2228 is connected to the longitudinal loading bracket 2222, and the longitudinal telescopic end of the longitudinal motor 2228 is connected to the longitudinal slide plate 2226, so that the centrifuge tube grabbing part 224 moves perpendicular to the centrifuge tube conveyor belt 214. In this embodiment, the longitudinal loading bracket 2222 serves as a supporting base for longitudinal movement, and the longitudinal slide rail 2224 is fixed on the longitudinal loading bracket 2222, so that the longitudinal slide 2226 can slide along the longitudinal slide rail 2224. Specifically, the longitudinal slide rail 2224 is arranged in a direction perpendicular to the centrifuge tube conveyor belt 214, so that the longitudinal slide 2226 drives the centrifuge tube grabbing member 224 to move longitudinally under the drive of the longitudinal motor 2228, so that the centrifuge tube grabbing member 224 can grab the centrifuge tube in a direction perpendicular to the centrifuge tube conveyor belt 214, thereby facilitating the synchronous removal of multiple linearly distributed centrifuge tubes in the single-tube linear conveying trough.

[0070] Furthermore, the centrifuge tube loading moving part 222 also includes a transverse loading bracket 2221, a transverse slide rail 2223 and a transverse motor 2225, the transverse motor 2225 is arranged on the longitudinal slide 2226, the transverse slide rail 2223 is arranged on the transverse loading bracket 2221, the longitudinal slide 2226 is slidably connected to the transverse slide rail 2223, and the transverse loading bracket 2221 is respectively connected to the transverse telescopic end of the transverse motor 2225 and the centrifuge tube grabbing part 224, so that the centrifuge tube grabbing part 224 moves along a direction parallel to the centrifuge tube conveyor belt 214. In this embodiment, the transverse loading bracket 2221 serves as a transverse moving support base for the centrifuge tube grabber 224, the transverse slide rail 2223 is fixed on the transverse loading bracket 2221, and the longitudinal slide plate 2226 moves transversely relative to the transverse loading bracket 2221 through the transverse slide rail 2223. Specifically, the transverse slide rail 2223 is arranged in a direction parallel to the centrifuge tube conveyor belt 214. The transverse telescopic end of the transverse motor 2225 pushes the transverse loading bracket 2221, so that the transverse loading bracket 2221 moves transversely through the transverse slide rail 2223, so that the transverse loading bracket 2221 drives the centrifuge tube grabber 224 to move transversely, so that after taking out multiple centrifuge tubes from the single-tube linear conveying trough, the multiple centrifuge tubes are transferred to the subsequent loading mechanism together through the transverse motor 2225.

[0071] In one embodiment, see Figure 7 The centrifuge tube grabbing member 224 includes a grabbing connecting plate 2242 and two oppositely arranged grabbing clamping plates 2244. The grabbing connecting plate 2242 is respectively connected to the two grabbing clamping plates 2244, and the moving end of the centrifuge tube loading moving member 222 is connected to one of the grabbing clamping plates 2244. In this embodiment, the grabbing connecting plate 2242 serves as a fixed connection component between the two grabbing clamping plates 2244. Specifically, one end of the grabbing connecting plate 2242 is connected to one of the grabbing clamping plates 2244, and the other end of the grabbing connecting plate 2242 is connected to the other grabbing clamping plate 2244, and the two grabbing clamping plates 2244 are kept parallel to each other. The two grabbing connecting plates 2242 move driven by the centrifuge tube loading moving part 222, so that the two grabbing connecting plates 2242 can jointly clamp multiple linearly distributed centrifuge tubes in the single-tube linear conveying trough. For example, the spacing between the two grabbing clamping plates 2244 is equal to the width of the centrifuge tube.

[0072] Furthermore, the centrifuge tube grabber 224 also includes a grabbing image collector 2246, which is connected to at least one of the grabbing clamping plates 2244, and the collection end of the grabbing image collector 2246 faces the single-tube linear conveying trough. In this embodiment, the grabbing image collector 2246 is located on the grabbing clamping plate 2244, and the grabbing image collector 2246 is used to collect the aggregation of the centrifuge tubes in the single-tube linear conveying trough. Specifically, the grabbing image collector 2246 collects the arrangement image of the centrifuge tubes in the single-tube linear conveying trough to determine the distribution and filling of the centrifuge tubes in the single-tube linear conveying trough. In this way, when the centrifuge tubes in the single-tube linear conveying trough are filled, the centrifuge tube loading moving member 222 is triggered, so that the centrifuge tubes in the single-tube linear conveying trough can be taken out and loaded at one time through the centrifuge tube grabber 224.

[0073] Furthermore, the centrifuge tube transmission assembly 210 also includes a tube baffle plate 218, which is disposed on the centrifuge tube conveyor belt 214, and is located at the conveying terminal of the single-tube linear conveyor trough, and is used to hold the centrifuge tube in the single-tube linear conveyor trough. In this embodiment, the tube baffle plate 218 is located at the end of the conveying direction of the centrifuge tube conveyor belt 214, and the tube baffle plate 218 and the two transmission baffles 216 form a "U"-shaped structure, which is convenient for limiting the number of centrifuge tubes in the single-tube linear conveyor trough, avoiding the centrifuge tubes from being squeezed out of the single-tube linear conveyor trough, and ensuring that each centrifuge tube is captured.

[0074] In another embodiment, the end of the grabbing and clamping plate 2244 slides on the side of the tube blocking plate 218, and the tube blocking plate 218 and the centrifuge tube conveyor belt 214 are arranged perpendicular to each other. In this embodiment, the end of the grabbing and clamping plate 2244 abuts against the side of the tube blocking plate 218, and the grabbing and clamping plate 2244 slides along the side of the tube blocking plate 218, so that the moving direction of the grabbing and clamping plate 2244 is limited by the tube blocking plate 218, so that the tube blocking plate 218 can guide the movement of the grabbing and clamping plate 2244.

[0075] In one embodiment, see Figure 8The centrifuge tube flipping device further includes a bagging mechanism 400, and the bagging mechanism 400 includes a material unloading assembly 410 and a centrifuge tube bagging assembly 420. The material unloading assembly 410 includes a material unloading base 412, a material unloading grabbing member 414, and a material unloading pushing member 416. The material unloading grabbing member 414 and the material unloading pushing member 416 are both arranged on the material unloading base 412. The material unloading grabbing member 414 is used to grab a plurality of centrifuge tubes and transfer them to the material unloading pushing member 416. The material unloading pushing member 416 is used to push the centrifuge tubes. The centrifuge tube bagging assembly 420 includes a bagging base 422, a flip tube loading component 424 and a bagging transfer component 426. The flip tube loading component 424 includes a flip motor 4242 and a flip plate 4244. The flip motor 4242 is arranged on the bagging base 422. The flip plate 4244 is connected to the rotating shaft of the flip motor 4242. The end of the flip plate 4244 is used to install a centrifuge tube plastic bag. The end of the flip plate 4244 is located corresponding to the pushing end of the unloading pushing component 416, so that the centrifuge tube plastic bag can be loaded into the centrifuge tube. The bagging transfer member 426 includes a transfer slide rail 4262 and a bagging clamp 4264. The transfer slide rail 4262 is set on the bagging base 422. The bagging clamp 4264 is slidably set on the transfer slide rail 4262. The bagging clamp 4264 is used to clamp and fix the centrifuge tube plastic bag loaded into the centrifuge tube.

[0076] In this embodiment, after the unloading grabbing member grabs the centrifuge tube onto the unloading pushing member, the unloading pushing member pushes the centrifuge tube to the end, and the flip plate corresponds to the pushing end, so that the centrifuge tube plastic bag on the flip plate is aligned with the pushing end, which facilitates the centrifuge tube to accurately fall into the centrifuge tube plastic bag. After the centrifuge tube plastic bag is filled with centrifuge tubes, the bagging clamping member clamps the centrifuge tube plastic bag and transports it to the recycling process through the transfer slide rail, thereby realizing the rapid bagging of the centrifuge tubes.

[0077] In one embodiment, see Figure 8The flip plate 4244 includes a rotating body 4244a and a bagging rod 4244b. The rotating body 4244a is connected to the rotating shaft of the flip motor 4242, and the bagging rod 4244b is connected to the rotating body 4244a. The bagging rod 4244b corresponds to the pushing end of the unloading pushing member 416, and the bagging rod 4244b is used to install a centrifuge tube plastic bag. In this embodiment, the rotating body 4244a rotates around the rotating shaft of the flipping motor 4242, and the side of the rotating body 4244a is connected to the bagging rod 4244b, so that the bagging rod 4244b can fix the centrifuge tube plastic bag. In this way, after the centrifuge tube plastic bag is fixed on the bagging rod 4244b, the flipping motor 4242 rotates the rotating body 4244a, so that the bagging rod 4244b rotates the centrifuge tube plastic bag to below the pushing end of the unloading pushing member 416, so as to facilitate the accurate loading of the centrifuge tube into the centrifuge tube plastic bag.

[0078] Furthermore, the number of the bagging rods 4244b is two, and the two bagging rods 4244b are arranged opposite to each other. In this embodiment, the two bagging rods 4244b are respectively located on both sides of the rotating body 4244a. Specifically, the two bagging rods 4244b are symmetrically arranged with the rotating body 4244a as the center, and the two bagging rods 4244b are respectively fixed with a centrifuge tube plastic bag on both sides of the rotating body 4244a. For example, the flip plate 4244 has a "Z"-shaped structure, and the bag openings of the two centrifuge tube plastic bags are in opposite directions, so that after the rotating body 4244a is flipped, the two centrifuge tube plastic bags are respectively bagged with centrifuge tubes, so as to improve the bagging efficiency of the centrifuge tubes.

[0079] In one embodiment, see Figure 8The centrifuge tube bagging assembly 420 further includes a bagging member 428, the bagging member 428 includes a bagging bottom plate 4282 and a bagging seat 4284, the bagging bottom plate 4282 is connected to the bagging rod 4244b, the bagging bottom plate 4282 is provided with a pipe loading port 402, the bagging seat 4284 is connected to the bagging bottom plate 4282, the bagging seat 4284 has a pipe loading channel 404 connected to the pipe loading port 402, and the bagging seat 4284 is used to cover the centrifuge tube plastic bag. In this embodiment, the bagging bottom plate 4282 serves as a connecting member between the bagging seat 4284 and the bagging rod 4244b, the bagging bottom plate 4282 is provided with the bagging seat 4284, and the bagging seat 4284 is used to cover the centrifuge tube plastic bag, specifically, the bag opening of the centrifuge tube plastic bag passes through the bagging seat 4284 and is covered thereon. The tube loading channel 404 is opened on the bagging seat 4284, and the tube loading port 402 is opened on the bagging bottom plate 4282. When the centrifuge tube plastic bag is mounted on the bagging seat 4284, the bottom of the centrifuge tube plastic bag abuts against the bagging seat 4284, so that the tube loading channel 404 and the tube loading port 402 are simultaneously connected to the interior of the centrifuge tube plastic bag, so that the centrifuge tube is conveniently loaded into the centrifuge tube plastic bag after passing through the tube loading port 402 and the tube loading channel 404.

[0080] Furthermore, the bagging member 428 further includes a branching plate 4286, which is disposed in the tube loading channel 404, and the branching plate 4286 and the bagging bottom plate 4282 are disposed perpendicular to each other. In this embodiment, the branching plate 4286 is connected to the side wall of the tube loading channel 404, and the branching plate 4286 divides the tube loading channel 404 into two, so as to facilitate the division of the internal space of the centrifuge tube plastic bag, thereby facilitating the neat loading of the centrifuge tubes under the guidance of the branching plate 4286.

[0081] In another embodiment, the bagging seat 4284 has a bagging slope 406, and the bagging slope 406 is inclined in a direction away from the bagging bottom plate 4282, and the bagging slope 406 is used to slide against the inner wall of the centrifuge tube plastic bag. In this embodiment, the bagging slope 406 is located at one end of the bagging seat 4284 away from the bagging bottom plate 4282, and the bagging slope 406 presents a pointed structure at the bagging end of the bagging seat 4284, that is, in the direction close to the bagging bottom plate 4282, the end diameter of the bagging seat 4284 gradually decreases, so as to facilitate the centrifuge tube plastic bag to be guided and put on the bagging seat 4284.

[0082] In another embodiment, the centrifuge tube bagging assembly 420 also includes a bag fixing component 421, and the bag fixing component 421 includes a bag fixing motor 4212 and a fixed clamping block 4214. The bag fixing motor 4212 is connected to the bag bottom plate 4282, and the fixed clamping block 4214 is connected to the telescopic end of the bag fixing motor 4212, so that the fixed clamping block 4214 can hold the centrifuge tube plastic bag against the bag seat 4284. In this embodiment, the bag fixing motor 4212 is fixed on the bag bottom plate 4282, and the bag fixing motor 4212 retracts and contracts the fixed clamping block 4214 so that the fixed clamping block 4214 approaches or moves away from the bag seat 4284, so that the fixed clamping block 4214 can hold the centrifuge tube plastic bag against the bag seat 4284, that is, the fixed clamping block 4214 and the bag seat 4284 jointly clamp the centrifuge tube plastic bag, thereby facilitating greater stability when flipping and loading the centrifuge tube.

[0083] Furthermore, there are two bag fixing parts 421, which are relatively arranged at the two ends of the bag bottom plate 4282, so as to facilitate clamping the centrifuge tube plastic bag in two relative directions, thereby further improving the stability of the centrifuge tube plastic bag on the bag seat 4284.

[0084] In one embodiment, see Fig. 9The centrifuge tube flipping device further includes a plastic bag supply mechanism 500, and the plastic bag supply mechanism 500 includes a centrifuge tube bagging component 510 and a plastic bag transmission component 520. The centrifuge tube bagging component 510 includes a bagging base 512 and a centrifuge tube bagging component 514, and the centrifuge tube bagging component 514 includes a bagging motor 5142, a bagging rotating plate 5144, and a bagging seat 5146. The bagging motor 5142 is disposed on the bagging base 512, the bagging rotating plate 5144 is connected to the rotating shaft of the bagging motor 5142, the bagging seat 5146 is connected to the bagging rotating plate 5144, and the bagging seat 5146 is provided with a tube loading channel 502, and the bagging seat 5146 is used to correspond to the tube loading lowering position so that the centrifuge tube is loaded into the tube loading channel 502. The plastic bag transmission component 520 includes a plastic bag base 522, a plastic bag conveyor belt 524, a plastic bag upper belt piece 526 and a plastic bag lower belt piece 528. The plastic bag conveyor belt 524, the plastic bag upper belt piece 526 and the plastic bag lower belt piece 528 are all arranged on the plastic bag base 522. The plastic bag upper belt piece 526 is located at the transmission starting end of the plastic bag conveyor belt 524. The plastic bag upper belt piece 526 is used to transfer the centrifuge tube sealing bag to the plastic bag conveyor belt 524. The plastic bag lower belt piece 528 is located at the transmission end of the plastic bag conveyor belt 524. The plastic bag lower belt piece 528 is used to open the bag mouth of the centrifuge tube sealing bag and put it on the bagging seat 5146.

[0085] Among them, the bagging base is equivalent to the bagging base, and the centrifuge tube bagging part is equivalent to the flip tube loading part.

[0086] In this embodiment, the centrifuge tube sealing bag is transported on the plastic bag conveyor belt 524. When the centrifuge tube sealing bag moves to the end of the plastic bag conveyor belt 524, the plastic bag lower belt member 528 grabs the centrifuge tube sealing bag to open the bag mouth of the centrifuge tube sealing bag. Then, the plastic bag lower belt member 528 transfers the centrifuge tube sealing bag with the bag mouth opened to the bagging base 512, so that the centrifuge tube sealing bag can be mounted on the bagging base 512. Finally, the bagging motor 5142 rotates the bagging rotating plate 5144, so that the opening of the tube loading channel 502 of the centrifuge tube sealing bag rotates toward the tube loading lower position, thereby facilitating the rapid loading of the centrifuge tube into the centrifuge tube sealing bag, thereby effectively improving the bagging efficiency of the centrifuge tube.

[0087] In one embodiment, see Fig. 9The plastic bag upper belt member 526 includes an upper belt bracket 5262, an upper belt transverse slide rail 5264, and an upper belt absorber 5266. The upper belt bracket 5262 spans the transmission start end of the plastic bag conveyor belt 524. The upper belt transverse slide rail 5264 is arranged on the upper belt bracket 5262. The upper belt absorber 5266 is slidably arranged on the upper belt transverse slide rail 5264. The upper belt absorber 5266 is used to absorb and transfer the centrifuge tube sealed bag to the plastic bag conveyor belt 524. In this embodiment, the upper belt bracket 5262 serves as the upper belt transverse slide rail 5264 and the upper belt absorber 5266. The upper belt absorber 5266 slides on the upper belt transverse slide rail 5264. The upper belt absorber 5266 transfers the centrifuge tube sealed bag from the placement area to the transmission start end of the plastic bag conveyor belt 524, so as to facilitate the loading of the centrifuge tube sealed bag.

[0088] In another embodiment, the upper belt adsorber is a negative pressure suction cup device, and the centrifuge tube sealing bag is adsorbed on the suction cup by negative pressure.

[0089] Furthermore, the plastic bag upper belt member 526 further includes an upper belt longitudinal slide rail 5268, which is slidably disposed on the upper belt transverse slide rail 5264, and the upper belt absorber 5266 is slidably connected to the upper belt longitudinal slide rail 5268. In this embodiment, the upper belt longitudinal slide rail 5268 is located between the upper belt transverse slide rail 5264 and the upper belt absorber 5266, and the upper belt absorber 5266 is longitudinally moved by the upper belt longitudinal slide rail 5268, so that the upper belt absorber 5266 can move in a direction perpendicular to the plastic bag conveyor belt 524, thereby facilitating the centrifuge tube sealing bag to approach or move away from the plastic bag conveyor belt 524, and further facilitating the centrifuge tube sealing bag to be flatly placed on the plastic bag conveyor belt 524.

[0090] Furthermore, the upper belt transverse slide rail 5264 is parallel to the plastic bag conveyor belt 524, and the upper belt longitudinal slide rail 5268 is perpendicular to the upper belt transverse slide rail 5264. In this embodiment, the upper belt transverse slide rail 5264 spans the plastic bag conveyor belt 524, and the upper belt longitudinal slide rail 5268 is perpendicular to the surface of the plastic bag conveyor belt 524, so that the upper belt adsorber 5266 moves in two perpendicular directions, which is convenient for transferring the centrifuge tube sealed bag to the plastic bag conveyor belt 524 with accuracy and stability.

[0091] In one embodiment, the upper belt member 526 of the plastic bag further includes a sealed bag storage bracket 5261, which is arranged at one side of the transmission starting end of the plastic bag conveyor belt 524, and the sealed bag storage bracket 5261 has a storage area, and the storage area is used to place the centrifuge tube sealed bag. In this embodiment, the sealed bag storage bracket 5261 corresponds to the upper belt member 526 of the plastic bag, specifically, the sealed bag storage bracket 5261 is arranged adjacent to the upper belt member 526 of the plastic bag, and the sealed bag storage bracket 5261 is located at one side of the plastic bag conveyor belt 524. In this way, the centrifuge tube sealed bag in the storage area on the sealed bag storage bracket 5261 can be adsorbed and removed by the upper belt absorber 5266, so as to facilitate the rapid transfer of the centrifuge tube sealed bag to the plastic bag conveyor belt 524.

[0092] In one embodiment, see Fig.10 The plastic bag lower belt member 528 includes a lower belt transverse slide rail 5282 and a lower belt absorber 5284. The lower belt transverse slide rail 5282 is disposed at the transmission end of the plastic bag conveyor belt 524. The lower belt absorber 5284 is slidably disposed on the lower belt transverse slide rail 5282. The lower belt absorber 5284 is used to transfer the centrifuge tube sealed bag to the bagging seat 5146. In this embodiment, the lower belt transverse slide rail 5282 and the plastic bag conveyor belt 524 are parallel to each other. Specifically, one end of the lower belt transverse slide rail 5282 corresponds to the end of the plastic bag conveyor belt 524, and the other end of the lower belt transverse slide rail 5282 corresponds to the bagging seat 5146. The lower belt absorber 5284 sucks up the centrifuge tube sealing bag on the transmission end of the plastic bag conveyor belt 524, and the lower belt absorber 5284 slides along the lower belt transverse slide rail 5282 to the bag-covering seat 5146, so that the bag opening of the centrifuge tube sealing bag is aligned with the top of the bag-covering seat 5146, so as to facilitate the centrifuge tube sealing bag to be covered on the bag-covering seat 5146 during the continued movement of the lower belt absorber 5284.

[0093] Furthermore, the plastic bag lower belt member 528 also includes an expanding absorbent 5286, which is connected to the plastic bag base 522, and the absorption port of the expanding absorbent 5286 faces the lower belt absorbent 5284 to expand the bag opening of the centrifuge tube sealing bag. In this embodiment, the flared adsorber 5286 is arranged below the plastic bag conveyor belt 524, and the flared adsorber 5286 is arranged opposite to the lower belt adsorber 5284. Specifically, the flared adsorber 5286 and the lower belt adsorber 5284 are located on both sides of the centrifuge tube sealing bag, and the adsorption port of the flared adsorber 5286 and the adsorption port of the lower belt adsorber 5284 are both facing the centrifuge tube sealing bag, so that the flared adsorber 5286 and the lower belt adsorber 5284 adsorb the upper and lower surfaces of the bag opening of the centrifuge tube sealing bag, thereby expanding the bag opening of the centrifuge tube sealing bag, making it convenient for the centrifuge tube sealing bag to be mounted on the bag mounting seat 5146.

[0094] Furthermore, the plastic bag lower belt member 528 also includes a lower belt longitudinal slide rail 5288, which is slidably set on the lower belt transverse slide rail 5282, and the lower belt adsorber 5284 is slidably connected to the lower belt longitudinal slide rail 5288 to enable the lower belt adsorber 5284 to approach or move away from the plastic bag conveyor belt 524. In this embodiment, the lower belt longitudinal slide rail 5288 is located between the lower belt transverse slide rail 5282 and the lower belt adsorber 5284, the lower belt longitudinal slide rail 5288 moves along the lower belt transverse slide rail 5282, and the lower belt adsorber 5284 moves along the lower belt longitudinal slide rail 5288, so that the lower belt adsorber 5284 moves in two different directions. Specifically, the lower belt longitudinal slide rail 5288 and the surface of the plastic bag conveyor belt 524 are arranged perpendicular to each other, and the lower belt transverse slide rail 5282 is parallel to the conveying direction of the plastic bag conveyor belt 524. In this way, the lower belt adsorber 5284 can move in two vertical directions, so that after the centrifuge tube sealing bag is moved to the top of the bag-covering seat 5146, the centrifuge tube sealing bag can be quickly put on the bag-covering seat 5146 through the bag mouth through the lower belt longitudinal slide rail 5288.

[0095] In one embodiment, see Fig. 9The plastic bag supply mechanism 500 also includes a code component 530, which includes a code bracket 532, a code longitudinal slide rail 534 and a code printer 536. The code bracket 532 spans the plastic bag conveyor belt 524, and the code bracket 532 is located between the plastic bag upper belt member 526 and the plastic bag lower belt member 528. The code longitudinal slide rail 534 is connected to the code bracket 532, and the code printer 536 is slidably connected to the code longitudinal slide rail 534. The code printer 536 is used for coding the centrifuge tube sealing bag. In this embodiment, the code bracket 532 serves as a mounting frame for the code longitudinal slide rail 534 and the code printer 536. The code longitudinal slide rail 534 is located between the plastic bag upper belt 526 and the plastic bag lower belt 528. The code printer 536 slides on the code longitudinal slide rail 534, so that the code printer 536 is movable relative to the plastic bag conveyor belt 524, which is convenient for adjusting the alignment between the code printer 536 and the centrifuge tube sealing bag, thereby facilitating the spraying of corresponding coding information on each centrifuge tube sealing bag.

[0096] In one of the embodiments, the present disclosure further relates to a centrifuge tube filling machine, comprising the centrifuge tube flipping device described in any of the above embodiments. In this embodiment, a chassis, a conveying component and a centrifuge tube flipping component; the conveying component includes a centrifuge tube arrangement conveyor belt and a centrifuge tube flipping conveyor belt, the centrifuge tube arrangement conveyor belt and the centrifuge tube flipping conveyor belt are both arranged on the chassis, the centrifuge tube arrangement conveyor belt is used to convey centrifuge tubes arranged and distributed in phase, and the centrifuge tube flipping conveyor belt is used to convey centrifuge tubes arranged and distributed in a staggered manner; the centrifuge tube flipping component includes a gantry, a flipping slide rail and a flipping grabbing member, the gantry is arranged on the chassis, the gantry spans the centrifuge tube arrangement conveyor belt and the centrifuge tube flipping conveyor belt, the flipping slide rail is connected to the gantry, the flipping grabbing member is slidably connected to the flipping slide rail so that the flipping grabbing member moves between the centrifuge tube arrangement conveyor belt and the centrifuge tube flipping conveyor belt; the grabbing end of the flipping grabbing member faces the centrifuge tube arrangement conveyor belt and the centrifuge tube flipping conveyor belt, and the flipping grabbing member is used to grab a plurality of centrifuge tubes on the centrifuge tube arrangement conveyor belt to place them on the centrifuge tube flipping conveyor belt, and to turn at least some of the centrifuge tubes. After the centrifuge tubes are transferred to the bottom of the gantry through the centrifuge tube arrangement conveyor belt, the flipping grabbing member grabs the centrifuge tubes to the centrifuge tube flipping conveyor belt in multiple times. During the movement of the flipping grabbing member to grab the centrifuge tubes, the flipping grabbing member turns some of the centrifuge tubes so that the centrifuge tubes on the centrifuge tube flipping conveyor belt are placed in reverse, so that the centrifuge tube flipping conveyor belt is loaded with centrifuge tubes with staggered directions, which is convenient for quickly forming a staggered distribution of centrifuge tubes, thereby facilitating the subsequent staggered packaging of the centrifuge tubes.
