[0044] Example

[0045] See also Figures 1 to 9 The present embodiment provides a 96-well plate loading auxiliary device, which is used in the 96-well plate loading experiment process. The device includes: an adjustment bracket 100, an ice box placement cabinet 200 rotatably connected to the top of the adjustment bracket 100, a chamber is provided in the ice box placement cabinet 200, and a cold storage ice box 300 can be selectively placed in the chamber, and an auxiliary loading box 400 is detachably stacked on the top of the ice box placement cabinet 200, and the auxiliary loading box 400 is used for 96-well plate loading.

[0046] like Figure 2 As shown, a 96-well plate 500 is provided with sample tubes 510 in an array, and each sample tube 510 is provided with a tube hole 520 on the top, wherein the sample tubes 510 are arranged in 8x12. It can be understood that the 96-well plate 500 can be obtained from the market. This embodiment only provides one 96-well plate 500, and there are also 96-well plates 500 of other sizes, which are not specifically limited.

[0047] When a 96-well plate is needed for an experiment, the device can pre-adjust the angle and height, place the 96-well plate on the auxiliary loading box 400, and control the conveyor belt on the auxiliary loading box 400 to rotate by a remote control so that the loading holes of the conveyor belt are aligned with the test tube holes of the 96-well plate, thus completing the loading of the 96-well plate; by adjusting the setting of the bracket 100, the adjustment bracket 100 can adjust the height and the angle of the auxiliary loading box 400, which can effectively solve the blind spots of the experimenter's vision during the operation process, and at the same time, it is more convenient to use, by arranging an ice box placement cabinet 200 on the auxiliary loading box 400, in some experiments that need to add samples in a low-temperature environment to the 96-well plate, the ice box placement cabinet 200 can selectively place ice boxes, thus making the 96-well plate and the auxiliary loading box 400 in a low-temperature environment.

[0048] Next, the structure, position connection relationship and working principle of each component of the 96-well plate loading auxiliary device will be further described;

[0049] like Figure 3As shown, the adjustment bracket 100 includes a support 110, in the middle of which a telescopic rod 120 is vertically fixedly arranged, and a fixing button 121 is arranged on the telescopic rod 120, and the fixing button 121 is used to fix the telescopic rod 120 when it is extended to a corresponding length, and a universal ball groove is arranged on the top of the telescopic rod 120, and a universal ball 130 is rotatably connected in the universal ball groove, and a connecting bolt 131 is fixedly arranged on the top of the universal ball 130, and a tension adjustment knob 140 is arranged on the side wall of the universal ball groove, and one end of the tension adjustment knob 140 contacts the universal ball 130, so that the tightness of the universal ball 130 can be adjusted and fixed; the setting of the universal ball 130 can make the auxiliary loading box 400 adjusted to any tilt angle, and the setting of the telescopic rod 120 can adjust the height of the auxiliary loading box 400.

[0050] like Figure 4 and Figure 5 As shown, the ice box placement cabinet 200 is a rectangular box body, and the ice box placement cabinet 200 is surrounded by two long side panels 210, a bottom plate and two short side panels 220. A snap-in groove 221 is provided along the length direction on the top of the two short side panels 220, and the snap-in groove 221 is used to snap and fix the auxiliary sample loading box 400. A cabinet door 230 is provided on the surface of one of the short side panels 220. The cabinet door 230 can be selectively opened and closed by a hinge. Through the setting of the cabinet door 230, the cold storage ice box 300 can be selectively added into the auxiliary sample loading box 400.

[0051] Optionally, a connecting block 240 is provided in the middle of the bottom surface of the ice box placement cabinet 200, and the connecting block 240 has a bolt hole in the vertical direction, which is used to be screwed and fixed with the connecting bolt 131 set on the universal ball 130, thereby realizing a rotatable connection between the ice box placement cabinet 200 and the adjustment bracket 200.

[0052] It is understandable that a cold storage material can be placed in the cold storage ice box 300, which can be obtained from the market, and the cold storage ice box 300 can be placed in a refrigerator for freezing and can be reused.

[0053] like Figure 6 and Figure 7 As shown, the auxiliary loading box 400 is stacked on the top of the ice box placement cabinet 200, which includes a placement box slot 410, a conveyor belt 420 arranged around the surface of the placement box slot 410, and a power component 430 arranged at the bottom of the placement box slot 410 for providing power for the rotation of the conveyor belt 420, wherein one end face of the placement box slot 410 is open for placing a 96-well plate, and multiple groups of conveyor belts 420 are arranged in parallel along the length direction of the placement box slot 410, and each conveyor belt 420 has a loading hole 421 on its surface, and each conveyor belt 420 can be rotated along the winding direction.

[0054] It should be noted that digital numbers 422 are arranged at intervals on the surface of the conveyor belt, and the digital numbers 422 are composed of letters and numbers. For example, the surface of the first group of conveyor belts 420 is marked with A, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12; the surface of the second group of conveyor belts 420 is marked with B, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12; ...; the surface of the eighth group of conveyor belts 420 is marked with H, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12; letters can be used to indicate which row of the 96-well plate 500 it corresponds to, and 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 can be used to indicate the corresponding test tube holes in the same row. In this way, it can effectively avoid the experimenter from adding the wrong, missing or mixed additions, and at the same time, it is also convenient for the experimenter to perform the sample addition operation.

[0055] Preferably, the sample adding hole 421 is opened between the letters and the numbers. When sample adding is required, the motor is set so that the sample adding hole 421 can only move one hole position at a time. In this way, the sample adding hole 421 can be accurately aligned with the test tube hole of the 96-well plate 500 by controlling the motor, thereby effectively avoiding missed addition or repeated addition. When the sample adding operation is completed, each group of conveyor belts 420 can be controlled to reset.

[0056] Optionally, an extension plate 411 is provided at the bottom of the open end surface of the placement box slot 410, and a sealing plate 412 is provided on the side of the placement box slot 410 opposite to the open end surface to seal one side of the placement box slot 410. The bottom of the extension plate 411 and the bottom of the sealing plate 412 extend downward and are flush, and the extension length is greater than the lowest point of the conveyor belt 420, thereby ensuring that the conveyor belt 420 has enough space to rotate to avoid interference. A snap-in step portion 413 is provided along the length direction on the bottom end surface of the extension plate 411 and the bottom end surface of the sealing plate 412, and the snap-in step portion 413 is engaged with the snap-in slot 221.

[0057] In one example, see Figure 8 The power assembly 430 includes a mounting base 431 arranged on the bottom surface of the placement box slot 410 along the length direction, and the mounting base 431 is alternately provided with a first mounting slot 4311 and a second mounting slot 4312 along the length direction, and the power assembly also includes a micro motor 432 and a transmission roller 433, the micro motor 432 is installed in the first mounting slot 4311, and the transmission roller 433 is installed in the second mounting slot 4312, and each micro motor 432 output shaft is individually connected to a transmission roller 433.

[0058] Optionally, the number of transmission rollers 433 and micro motors 432 is equal to the number of conveyor belts 420. The circumferential surface of the transmission rollers 433 abuts against the inner surface of the conveyor belt 420. When one of the transmission rollers 433 rotates, it drives the corresponding conveyor belt 420 to rotate. The micro motor 432 can be a servo motor, which is connected to a controller (not shown in the figure). A signal receiver is provided in the controller. A signal is sent through a remote control, and the controller receives the signal to control the corresponding micro motor 432 to operate, thereby realizing the corresponding rotation of the conveyor belt 420. Since the signal receiving and control principles of the controller and the remote control are existing technologies, they are not elaborated here.

[0059] Optionally, roller assemblies 440 are provided along the length direction at the four corners of the outer surface of the placement box slot 410. The setting of the roller assemblies 440 prevents the conveyor belt 420 from interfering with the outer wall of the placement box slot 410, thereby ensuring the smooth rotation of the conveyor belt 420.

[0060] See also Fig. 9 The wheel roller assembly 440 includes a main shaft 441 and a driven wheel roller 442 coaxially sleeved on the main shaft 441 and rotatably connected. The main shaft 441 leaves a gap with the surface of the placement box slot 410 through a support block to facilitate the rotation of the driven wheel roller 442. The surface of each driven wheel roller 442 fits the inner surface of the conveyor belt 420. For example, the number of driven wheel rollers 442 is equal to the number of conveyor belts 420, and each driven wheel roller 442 corresponds to a conveyor belt 420. Limiting gaskets 443 are set on both sides of the driven wheel roller 442. The limiting gaskets 443 are used to limit the driven wheel roller 442 laterally so that the driven wheel roller 442 can only rotate around itself.

[0061] Roller assemblies 440 are provided on both sides of the placement box slot 410 near the top and the bottom along the length direction. The roller assembly 440 includes a main shaft 441 and a driven roller 442 coaxially sleeved and rotatably connected to the main shaft 441 .

[0062] In the above technical solution, by setting the conveyor belt 420, a digital number 422 is set on the surface of the conveyor belt 420. The setting of the digital number 422 and the sample addition hole 421 are opened on the surface of the conveyor belt 420. The bottom of each conveyor belt 420 corresponds to a row of test tube holes of a 96-well plate. The setting of the digital number 422 and the sample addition hole 421 can solve the problem that it is difficult for the experimenter to find the sample test tube, and reduce the operation burden of the experimenter;

[0063] When it is necessary to add samples, the micro motor 432 corresponding to the conveyor belt 420 is controlled to align the sample adding hole 421 with the sample adding tube 510 of the corresponding 96-well plate, thereby completing the sample adding. The setting of the digital number 422 and the conveyor belt 420 can effectively prevent the experimenter from adding the wrong sample, missing the sample, or mixing the sample. At the same time, since the top of the 96-well plate is covered by the conveyor belt 420 and each conveyor belt 420 has a hole, during the experiment, it can effectively prevent some tiny particles or impurities from easily entering the hole, causing the well plate to be contaminated and affecting the experimental results.

[0064] At the same time, by adjusting the setting of the bracket 100, the height of the adjustable bracket 100 and the angle of the auxiliary sample loading box 400 can be adjusted, which can effectively solve the blind spots of the experimenter's vision during the operation process, making it more convenient to use. In addition, by setting an ice box placement cabinet 200 on the auxiliary sample loading box 400, in some experiments that require adding samples in a low-temperature environment to a 96-well plate, the ice box placement cabinet 200 can selectively place an ice box, so that the 96-well plate and the auxiliary sample loading box 400 are in a low-temperature environment.
