[0062] As Figures 1 - 14 shown, the present invention provides an automatic chromosome dropping device, which includes a machine body 100, a turntable 200, a first driving component, a dropping component and a homogenizing component.

[0063] Among them, the turntable 200 is installed on the machine body 100, and the turntable 200 is rotationally connected to the machine body 100 so that the turntable 200 can rotate around its own rotation center line. m positioning grooves are evenly arranged on the top of the turntable 200, where m≥2, and the positioning grooves are used for placing glass slides.

[0064] The first driving component is installed on the machine body 100, and the power output end of the first driving component is in transmission connection with the power input shaft of the turntable 200 to drive the turntable 200 to rotate. Specifically, in this embodiment, the first driving component drives the turntable 200 to rotate intermittently, and the rotation angle each time is α, where α = 360° / m.

[0065] The dropping component is installed on the machine body 100, and the dropping component is located above the positioning groove. The dropping component is used to drop a target volume of chromosome suspension onto a target glass slide. The homogenizing component is installed on the frame, and the homogenizing component is used to make the chromosome suspension on the target glass slide evenly distributed.

[0066] Specifically, during the working process, the staff places the glass slide in the corresponding positioning groove. The first driving component drives the turntable 200 to rotate, so that the positioning groove with the glass slide placed therein moves towards the liquid dropping station (i.e., the position corresponding to the liquid dropping component), and the positioning groove without the glass slide placed therein moves towards the feeding station (i.e., the position corresponding to the feeding staff).

[0067] When the positioning groove with the glass slide placed therein moves to the liquid dropping position, under the action of the liquid dropping component, the liquid dropping component drops a preset volume of chromosome suspension onto the glass slide. When the positioning groove without the glass slide placed therein moves to the feeding station, the feeding staff places a glass slide into the positioning groove.

[0068] The glass slide with the chromosome suspension dropped thereon, under the action of the vibration structure, the vibration structure drives the glass slide to vibrate, so as to achieve the purpose of making the chromosome suspension evenly distributed on the glass slide.

[0069] As Figure 2 、 3 As shown in 9, 10, 14, in this embodiment, the liquid dropping component includes a liquid dropping head 410, a liquid storage tank 420, a high-precision metering pump 430 and a control valve 440.

[0070] Among them, the liquid dropping head 410 is located above the turntable 200, and the liquid dropping head 410 is fixedly connected to the machine body 100. The liquid storage tank 420 is arranged on the machine body 100, and the liquid storage tank 420 is fixedly connected to the machine body 100. The inlet of the high-precision metering pump 430 is communicated with the liquid storage tank 420 through a liquid inlet pipe, and the outlet is communicated with the liquid dropping head 410 through a liquid outlet pipe. There are two control valves 440, and the two control valves 440 are respectively arranged on the liquid inlet pipe and the liquid outlet pipe to control the on-off of the liquid inlet pipe and the liquid outlet pipe.

[0071] Specifically, during use, the control valve 440 and the high-precision metering pump 430 are turned on. Under the action of the high-precision metering pump 430, the chromosome suspension in the liquid storage tank 420 is conveyed to the liquid dropping head 410 and finally drops onto the glass slide below. The structure is simple and the design is reasonable. It can not only accurately control the liquid dropping amount, but also change the liquid dropping volume by changing the conveying volume of the high-precision metering pump 430, so as to achieve the purpose of adjusting the liquid dropping amount according to factors such as the type of glass slide and experimental requirements.

[0072] As Figure 3 、 10 As shown in, the first driving component includes a first motor 310.

[0073] Among them, the first motor 310 is fixedly installed on the machine body 100, and the power output shaft of the first motor 310 is in transmission connection with the power input shaft of the turntable 200 to drive the turntable 200 to rotate. Preferably, the first motor 310 is a servo motor to facilitate precise control of the rotation angle and accuracy of the turntable 200 each time.

[0074] As Figures 3 - 7 shown, in this embodiment, the homogenization component includes a vibration seat 511 and a vibration structure.

[0075] The vibration seat 511 is installed on the turntable 200 and can rotate synchronously with the turntable 200. The vibration seat 511 is movably connected to the turntable 200 so that the vibration seat 511 can vibrate on the turntable 200. There are m vibration seats 511, and the m vibration seats 511 are evenly arranged around the axis of the turntable 200. m positioning grooves are respectively opened on the m vibration seats 511.

[0076] The vibration structure is arranged on the turntable 200, and the vibration structure is in transmission connection with the vibration seat 511. The vibration structure is used to drive the vibration seat 511 to vibrate, thereby driving the glass slide placed in the positioning groove to vibrate, and further making the chromosome suspension dropped on the glass slide evenly distributed.

[0077] As Figures 3 - 7 shown, in this embodiment, the vibration structure includes a vibration element 512 and a drive circuit 513.

[0078] The vibration element 512 is made of piezoelectric ceramics. The vibration element 512 corresponds to the vibration seat 511 one by one, and the vibration element 512 is fixedly connected to the vibration seat 511. The input circuit of the drive circuit 513 is electrically connected to the power supply, and the output circuit is electrically connected to the vibration element 512. The drive circuit 513 includes a signal generator, a power amplifier, and a voltage regulation module.

[0079] Among them, the power amplifier is electrically connected to the voltage regulation module, the signal generator, and the vibration element 512.

[0080] The signal generator is used to generate a sine wave signal with a fixed frequency and transmit the sine wave signal to the power amplifier. The power amplifier is used to amplify the sine wave signal output by the signal generator and transmit the amplified signal to the vibration element 512. The voltage regulation module is used to change the DC bias voltage input to the power amplifier to adjust the amplitude of the AC voltage finally applied across the vibration element 512, so as to achieve the purpose of amplitude adjustment.

[0081] Specifically, during operation, the signal generator generates a sine wave signal with a fixed frequency as the basic driving signal and transmits the sine wave signal to the power amplifier. The power amplifier amplifies the received signal so that the power of the amplified signal reaches a power level sufficient to drive the vibration element 512 to vibrate, and transmits the amplified signal to the vibration element 512 to drive the vibration element 512 to vibrate, and the vibration element 512 then drives the vibration base 511 to vibrate.

[0082] During this process, the DC bias voltage input to the power amplifier is changed through the voltage regulation module, thereby adjusting the amplitude of the AC voltage finally applied across the vibration element 512, and further achieving the purpose of changing the vibration amplitude of the vibration element 512.

[0083] As Figures 3 - 6 shown, the vibration structure further includes a fixed electrode 514 and a moving electrode 515.

[0084] Among them, the fixed electrode 514 is fixedly connected to the body 100. There are two fixed electrodes 514, and the two fixed connections are respectively electrically connected to the positive and negative electrodes of the output circuit of the drive circuit 513. The moving electrode 515 is arranged on the turntable 200 and can rotate synchronously with the turntable 200. There are m groups of moving electrodes 515, and the m groups of moving electrodes 515 respectively correspond to m vibration elements 512. Each group of moving electrodes 515 has two, and the two moving electrodes 515 are respectively electrically connected to the positive and negative electrodes of the input circuit of the corresponding vibration element 512.

[0085] During operation, the turntable 200 rotates, so that the target moving electrode 515 (i.e., the moving electrode 515 corresponding to the target vibration element 512) corresponds to the fixed electrode 514, thereby turning on the drive circuit 513 of the target vibration element 512, and further achieving the purpose of driving the target glass slide (i.e., the glass slide placed on the vibration base 511 corresponding to the target vibration element 512) to vibrate.

[0086] Specifically, during operation, after the liquid dropping assembly drops a target volume of chromosome suspension onto the target glass slide, the first drive assembly drives the turntable 200 to rotate, so that the target moving electrode 515 (the moving electrode 515 corresponding to the glass slide with the dropped chromosome suspension) corresponds to the fixed electrode 514, thereby turning on the drive circuit 513 of the target vibration element 512 (i.e., the vibration element 512 corresponding to the target electrode), and further achieving the purpose of driving the target glass slide to vibrate.

[0087] As Figures 3 - 6 shown, in this embodiment, the vibration structure further includes a first permanent magnet 516, a second permanent magnet 517, and an elastic element 518.

[0088] The moving electrode 515 is slidably connected to the turntable 200 so that the moving electrode 515 can move in a direction closer to or farther from the fixed electrode 514. The first permanent magnet 516 is fixedly sleeved at one end of the moving electrode 515 corresponding to the fixed electrode 514. The second permanent magnet 517 is fixedly sleeved at one end of the fixed electrode 514 corresponding to the moving electrode 515. And the magnetic properties of the opposite sides of the first permanent magnet 516 and the second permanent magnet 517 are different, so that when the first permanent magnet 516 and the second permanent magnet 517 correspond to each other, a magnetic attraction force can be generated between the first permanent magnet 516 and the second permanent magnet 517, thereby driving the moving electrode 515 to move in a direction closer to the fixed electrode 514, and further enabling the moving electrode 515 to contact the fixed electrode 514, so as to achieve the purpose of turning on the drive circuit 513 of the vibration element 512.

[0089] Both ends of the elastic element 518 are respectively connected to the moving electrode 515 and the turntable 200, and in the natural state, the elastic element 518 applies an elastic force to the moving electrode 515, so that the moving electrode 515 has a tendency to move in a direction away from the fixed electrode 514. Specifically, in this embodiment, the elastic element 518 is a spring.

[0090] Specifically, during the working process, when the fixed electrode 514 and the moving electrode 515 do not correspond to each other, under the action of the elastic force of the elastic element 518, the moving electrode 515 is held at the separation position, so that the moving electrode 515 cannot contact the fixed electrode 514. During the rotation of the turntable, the moving electrode 515 will not be damaged due to collision with the fixed electrode 514.

[0091] As the turntable 200 rotates, when the moving electrode 515 moves to a position corresponding to the fixed electrode 514, the first permanent magnet 516 and the second permanent magnet 517 correspond to each other. Under the action of the magnetic force between the first permanent magnet 516 and the second permanent magnet 517, the moving electrode 515 overcomes the elastic force of the elastic element 518 and moves in a direction closer to the fixed electrode 514. When the moving electrode 515 moves to the combined position, the moving electrode 515 contacts the fixed electrode 514, thereby turning on the drive circuit 513 of the vibration element 512, and through the magnetic attraction force between the first permanent magnet 516 and the second permanent magnet 517, the moving electrode 515 is in close contact with the fixed electrode 514, so as to achieve the purpose of improving the contact stability.

[0092] As Figures 10 - 13 shown, in this embodiment, the homogenizing assembly includes a rotating seat 520 and a second driving structure.

[0093] The rotating base 520 is arranged on the turntable 200 and can rotate synchronously with the turntable 200. The rotating base 520 is rotationally connected to the turntable 200 so that the rotating base 520 can rotate around its own axis. There are m rotating bases 520, and the m rotating bases 520 are evenly arranged around the axis of the turntable 200. m positioning grooves are respectively formed on the m rotating bases 520. The second driving structure is used to drive the rotating base 520 to rotate.

[0094] Specifically, during the working process, after the liquid dropping assembly drops the target volume of chromosome suspension onto the target glass slide, the second driving structure drives the rotating base 520 to rotate, thereby driving the glass slide placed in the rotating base 520 to rotate. Under the action of centrifugal force, the purpose of making the chromosome suspension dropped on the glass slide evenly distributed is achieved.

[0095] As Figures 10 - 13 shown, the second driving structure includes a gear 521 and a rack 522.

[0096] The gear 521 is coaxially sleeved on the power input shaft of the rotating base 520. The rack 522 is arc-shaped, and the center line of the rack 522 coincides with the axis of the turntable 200. The rack 522 is fixedly connected to the machine body 100. During operation, as the turntable 200 rotates, the gear 521 meshes with the rack 522, thereby driving the rotating base 520 to rotate through the gear 521.

[0097] Specifically, during the working process, the first driving assembly drives the turntable 200 to rotate, and the turntable 200 drives the gear 521 to revolve. During the revolution of the gear 521 along with the turntable 200, the gear 521 meshes with the rack 522, thereby driving the gear 521 to rotate self, and then driving the rotating base 520 to rotate self. The rotating base 520 drives the glass slide to rotate. Under the action of centrifugal force, the purpose of making the chromosome suspension on the glass slide evenly distributed is achieved.

However, it can be understood that the embodiments of the present invention may be practiced without these specific details.
