Description

Technical Field

[0001] The invention relates to a centrifugal dyeing all-in-one machine, belonging to the technical field of biological experimental equipment. Background Art

[0002] In centrifugal experiment operations, the layout of the tubes placed on the tube holders of traditional devices is unreasonable. It is often difficult to ensure that the centrifuge tubes are easy to take and put, and to avoid interference between the placed tubes when rotating the tube holder to pour the supernatant. This brings inconvenience to the experimental operation and is not conducive to the efficient pouring of the supernatant. More importantly, in the process of pouring the supernatant, cells are easily poured out along with the supernatant, resulting in cell loss. This is because the traditional device lacks a mechanism that can cleverly control the rotation angle of the centrifuge tube, so that when pouring the supernatant, the cells will accumulate toward the tilted side of the centrifuge tube. During subsequent pouring, the cells are easily poured out, which seriously affects the accuracy and reliability of the experiment and increases the experimental error. Therefore, a centrifugal staining all-in-one machine is proposed. Summary of the Invention

[0057] The present invention is described below with specific examples, but is not intended to be limiting of the invention.

[0058] Example 1

[0059] like Figures 1-11As shown, in this embodiment, a centrifugal dyeing all-in-one machine is provided, including a workbench 1, a centrifugal module 2 is provided on the workbench 1, and the centrifugal module 2 includes a collecting box 201, which is installed on the workbench 1, and a drain pipe 2011 is provided at the lower end of the collecting box 201, and the drain pipe 2011 can be connected to a water pipe for leading out the liquid collected in the collecting box 201; a centrifugal frame 202 is rotatably connected to the collecting box 201 through a driving member; a plurality of tube seats 203 are distributed circumferentially on the centrifugal frame 202, and a plurality of centrifuge tubes can be placed on each tube seat 203; wherein, support shafts 3 are provided on both sides of each tube seat 203, and each support shaft 3 is rotatably connected to the centrifugal frame 202, and a gear rod 4 is slidably connected to the position of each support shaft 3 on the centrifugal frame 202 through a spring 5, and the gear rod 4 is meshed with the corresponding support shaft 3;

[0060] When the gear rod 4 compresses the spring 5 upward and slides upward, the gear rod 4 drives the support shaft 3 to rotate, causing the tube seat 203 to flip around the support shaft 3, thereby dumping the supernatant in the centrifuge tube.

[0061] A rotating shaft 10 is rotatably connected to the workbench 1. The upper end of the rotating shaft 10 passes through the side wall of the collecting box 201 and is fixed to the center of the centrifugal frame 202. The driving member is a stepper motor 11. The stepper motor 11 is fixedly installed on the workbench 1. The output end of the stepper motor 11 and the rotating shaft 10 are connected by a belt. When the stepper motor 11 rotates, the stepper motor 11 can drive the centrifugal frame 202 to rotate through the transmission of the belt and the rotating shaft.

[0062] Square grooves 2031 are formed on both sides of the tube base 203 , and a square block 301 is fixedly connected to the support shaft 3 , and the square block 301 is inserted into the square grooves 2031 .

[0063] The workbench 1 is also provided with an extraction module 101, a pipetting module 102 and a staining module 103. The extraction module 101 and the staining module 103 are respectively located on both sides of the centrifugal module 2. The pipetting module 102 is suspended above the extraction module 101, the staining module 103 and the centrifugal module 2. The pipetting module 102 can absorb the cell suspension and release it into the centrifugal module 2 (in the centrifuge tube placed in the cylinder 6). The centrifugal module 2 can separate the cells in the centrifuge tube from the solution, and then remove the supernatant in the centrifuge tube, and then use the pipetting module 102 to extract the cell fluid in the centrifuge tube to the staining module 103 for staining.

[0064] Example 2

[0065] like Figure 3-Figure 9 as well as Figure 11As shown, based on the first embodiment, in this embodiment, two rows of placement tubes 6 with open upper ends for placing centrifuge tubes are provided on the tube holder 203. After the centrifuge tubes are inserted into the placement tubes 6, the upper ends of the centrifuge tubes are higher than the placement tubes 6, which facilitates the removal and placement of the centrifuge tubes.

[0066] like Figure 2-Figure 3 As shown, each tube seat 203 is provided with two rows of placement tubes 6, and the two rows of placement tubes 6 are staggered. When the tube seat 203 is rotated to pour out the supernatant in the centrifuge tube, the two staggered rows of placement tubes 6 do not interfere with each other, thereby facilitating the pouring out of the centrifuged supernatant.

[0067] The placement cylinder 6 is rotatably connected to the tube base 203. A driven wheel 602 is fixed at the center of the bottom of the placement cylinder 6. The driven wheels 602 of each row of placement cylinders 6 are connected via a belt drive. A driving wheel 7 is fixed at the bottom of the tube base 203. The driving wheel 7 is meshed with a driven wheel 602 on each row of placement cylinders 6.

[0068] When the driving wheel 7 rotates, the driving wheel 7 rotates the two rows of placement cylinders 6 through the driven wheel 602.

[0069] A protective cover 8 for covering the driven wheel 602 and the driving wheel 7 is fixed below the pipe seat 203 .

[0070] The driving mechanism 9 is further comprised of a column 901 for driving the driving wheel 7 to rotate. The column 901 is fixed on the protective cover 8. A sleeve 902 is slidably connected to the column 901. Figure 7 As shown, a vertical groove 9011 is provided on the side wall of the column 901, and the vertical groove 9011 is opened along the axial direction of the column 901. A slider 9022 is fixed on the inner wall of the sliding sleeve 902, and the slider 9022 is slidably connected in the vertical groove 9011. Under the cooperation of the slider 9022 and the vertical groove 9011, the sliding sleeve 902 can only slide in the axial direction of the column 901, and the two sides of the sliding sleeve 902 are symmetrically connected to two guide wheels 9021 for rotation; the lower end of the sliding sleeve 902 is rotatably connected to the gear 903, and a spring 904 is provided between the gear 903 and the column 901 for pressing the gear 903 downward; an inner rod is fixed to the middle part of the gear 903, and the upper end of the inner rod 905 passes through the column 901 and is fixed with a ridge rod 9051, which is slidably connected to the ridge groove 701 in the center of the driving wheel 7, as shown in FIG. Figure 8 As shown, the cross sections of the rib groove 701 and the rib rod 9051 are both polygonal, the shapes of the rib groove 701 and the rib rod 9051 are adapted to each other, and the rib groove 701 is opened along the axis of the driving wheel 7 .

[0071] The driving mechanism 9 further includes a base 906, which is fixed in the collection box 201. The base 906 is provided with an arc-shaped lower slide 9061 and an upper slide 9062. The end of the upper slide 9062 is rotatably connected to a rotating plate 9064 via a torsion spring 9063. The torsion spring 9063 is sleeved on the rotating shaft of the rotating plate 9064. One end of the torsion spring 9063 is fixed to the rotating shaft of the rotating plate 9064, and the other end of the torsion spring 9063 is fixed to the base 906. Under the torsion force of the torsion spring 9063, the end of the rotating plate 9064 is pressed against the lower slide 9061. A tooth wall 9065 is fixed to the base 906.

[0072] When the centrifugal rack 202 with a tube holder 203 rotates to the position of pouring the supernatant, the gear 903 faces the base 906, and the guide wheel 9021 faces the lower slide 9061. At this time, the arc center of the lower slide 9061 and the upper slide 9062 coincides with the axis of the support shaft 3 corresponding to the tube holder 203.

[0073] When the tube holder 203 rotates to pour the supernatant, the guide wheel 9021 rolls along the lower slide 9061, and the gear 903 and the tooth wall 9065 intersect. As the tube holder 203 rotates, the guide wheel 9021 can push the rotating plate 9064 away and slide normally on the lower slide 9061. At this time, the placement tube 6 does not rotate.

[0074] When the tube holder 203 rotates to reset, the guide wheel 9021 first slides into the lower slide 9061. When the guide wheel 9021 slides to the position of the rotating plate 9064, the guide wheel 9021 slides along the rotating plate 9064 to the upper slide 9062. At this time, the guide wheel 9021 moves upward with the sliding sleeve 902, and the sliding sleeve 902 moves upward with the gear 903. The gear 903 rolls on the tooth wall 9065. At this time, the driving wheel 7 drives the driven wheel 602 and the placement cylinder 6 to rotate at a rolling angle of 180 degrees. In this way, the placement cylinder 6 rotates 180 degrees with the centrifuge tube. When the tube holder 203 is rotated again to pour the supernatant, the supernatant will be poured out from the other side of the centrifuge tube, thereby preventing the cells from being poured out.

[0075] The supernatant was poured off twice. Figure 11 As shown, the upper end of the centrifuge tube is provided with a position a and a position b. When the centrifuge tube is rotated for the first time, the supernatant is poured out from the position a of the centrifuge tube. Since the centrifuge tube is tilted toward the position a when the supernatant is poured out, the deposited cells are accumulated toward the side of the position a. When the supernatant is poured out for the first time, the gear 903 and the tooth wall 9065 rotate to rotate the centrifuge tube 180 degrees. In this way, when the centrifuge tube is rotated for the second time, the supernatant will be poured out from the position b of the centrifuge tube, thereby effectively preventing the cells from being poured out during the supernatant pouring process.

[0076] A rubber sleeve 601 for reinforcing the centrifuge tube is glued to the inner wall of the placement cylinder 6 by structural adhesive. The inner ring of the rubber sleeve 601 is tightly attached to the centrifuge tube, which can fix the centrifuge tube inside the placement cylinder 6, increase the stability of the centrifugation process, and prevent the centrifuge tube from falling out of the placement cylinder 6 when the supernatant is poured out.

[0077] Example 3

[0078] like Figure 2-Figure 3 as well as Figure 10 As shown, based on the above embodiment, in this embodiment, two electric push rods 12 are provided on the bottom wall of the collection box 201. The output shafts of the two electric push rods 12 pass through the bottom wall of the collection box 201 and are respectively fixed with a top block 13 for pressing the gear rod 4 upward.

[0079] When the centrifugal frame 202 is rotated so that the two gear rods 4 on the same tube seat 203 are respectively located directly above the two top blocks 13, the top blocks 13 press the corresponding gear rods 4 upwards, thereby driving the tube seat 203 to flip around the support shaft 3;

[0080] When the top block 13 slides downward to reset, the spring 1 5 presses the gear rod 4 downward, and the pipe seat 203 rotates in the opposite direction to reset.

[0081] An intelligent sensor 14 is fixed inside the collection box 201, and a plurality of metal sheets 15 are fixed on the side wall of the centrifugal frame 202. The plurality of metal sheets 15 correspond one to one with the plurality of tube holders 203;

[0082] When any metal sheet 15 rotates with the centrifugal frame 202 to the sensing area of ​​the smart sensor 14 , the gear rods 4 on both sides of the corresponding tube seat 203 are respectively located directly above the two top blocks 13 , and the smart sensor 14 can be a position sensor.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
