[0030] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-2 , the present invention provides a technical solution: a cell waste liquid collection device, including a base 1, and further including: a transfer assembly 2, which is arranged at the middle position of the top surface of the base 1, and the transfer assembly 2 is used for transferring the well plate and adjusting its tilt angle; a suction assembly 3, which is arranged on the top surface of the base 1 and on one side of the transfer assembly 2, and the suction assembly 3 is used for sucking the waste liquid on the well plate; a support assembly 4, which is arranged on the top surface of the base 1 and between the transfer assembly 2 and the suction assembly 3, and the support assembly 4 is used for installing the liquid suction end of the suction assembly 3 and adjusting its position; and a control assembly 5, which is arranged on one side of the top surface of the base 1, and the control assembly 5 is used for controlling the operation of the transfer assembly 2, the suction assembly 3 and the support assembly 4;

[0032] First, the staff places the well plate containing the waste liquid at the designated position on the transfer assembly 2, and then through the control assembly 5, the operation of the transfer assembly 2 can be controlled, so that the transfer assembly 2 can move the well plate directly below the suction end of the suction assembly 3, and the well plate can be in a tilted state of 30° - 45° under the adjustment of the transfer assembly 2. Then, through the control assembly 5, the suction assembly 3 and the support assembly 4 can be controlled to start. Next, through the support assembly 4, the position of the liquid suction end of the suction assembly 3 can be automatically adjusted, so that the liquid suction end of the suction assembly 3 can be inserted into the hole slots in the uppermost row of the well plate, and then the cell waste liquid in the hole slots can be sucked. When the waste liquid in the uppermost row is sucked up, at this time, the control assembly 5 can not only control the support assembly 4 to drive the liquid suction end of the suction assembly 3 to slightly move away from the well plate, but also control the operation of the transfer assembly 2, so that the well plate can move closer to the support assembly 4. Then, the support assembly 4 drives the liquid suction end of the suction assembly 3 to be inserted into the hole slots in the second row from the top of the well plate again, so that the suction assembly 3 sucks the cell waste liquid again. Repeat the above operations to complete the collection of the cell waste liquid on the well plate, improving the overall collection efficiency of the cell waste liquid and reducing the working intensity.

[0033] Refer to Figure 1 , Figure 3, the transfer assembly 2 includes a U-shaped frame 21. Inside the U-shaped frame 21 and near the top position, a material carrier 22 is arranged. At both sides of the material carrier 22 and near one end position, a shaft rod 23 is arranged at each side. At one end of both sides of the inner cavity of the U-shaped frame 21 and near the top position, a shaft hole 24 for inserting the shaft rod 23 is opened at each side; on the bottom surface of the U-shaped frame 21, an electric linear slide 25 is arranged, and the bottom surface of the electric linear slide 25 is connected to the top surface of the base 1. On one side of the bottom surface of the inner cavity of the U-shaped frame 21, a first electric push rod 26 is arranged, and the telescopic end of the first electric push rod 26 is in contact with the bottom surface of the material carrier 22. In the middle of the bottom surface of the material carrier 22, an inclination sensor 27 is arranged. On both sides of the bottom surface of the U-shaped frame 21, a slider 28 is arranged at each side. On both sides of the top surface of the base 1, a slide rail 29 for guiding the slider 28 is arranged;

[0034] Through the U-shaped frame 21 in the transfer assembly 2, the two shaft rods 23 on the material carrier 22 can be inserted and installed through the two shaft holes 24, the first electric push rod 26 can be installed and fixed, and at the same time, it can be installed on the output end of the electric linear slide 25 located on the base 1. Since the inclination sensor 27 is arranged in the middle of the bottom surface of the material carrier 22, through the electric linear slide 25, the material carrier 22 equipped with the orifice plate can be driven to move through the U-shaped frame 21, and under the drive of the first electric push rod 26, the material carrier 22 can be driven to rotate around the shaft rod 23 as the axis, so as to be able to adjust the inclination position of the material carrier 22 and the orifice plate. And under the action of the inclination sensor 27, the orifice plate can be in a specified inclination angle, so as to facilitate the suction component 3 to suck the cell waste liquid. Since the sliders 28 are arranged on both sides of the bottom surface of the U-shaped frame 21, and the slide rails 29 for guiding the sliders 28 are arranged on both sides of the top surface of the base 1, the smoothness of the reciprocating movement of the U-shaped frame 21 can be ensured under the action of the sliders 28 and the slide rails 29.

[0035] Refer to Figures 2-4 , the suction component 3 includes a C-shaped frame 37. Inside the C-shaped frame 37, a detachable collection box 31 is arranged. On one side of the top surface of the C-shaped frame 37, a vacuum collection pump 32 is arranged. The suction end of the vacuum collection pump 32 is connected with a hose 33, and one end of the hose 33 is connected with a connector 34; the bottom end of the connector 34 is detachably connected with a suction sleeve 35, and the suction sleeve 35 is clamped at one end of the top of the support component 4. The output end of the vacuum collection pump 32 is connected with a delivery pipe 36, and the bottom end of the delivery pipe 36 is communicated and connected with the collection box 31;

[0036] Through the suction sleeve 35 in the suction component 3, it can be installed on the support component 4 and connected to the hose 33 at the suction end of the vacuum collection pump 32 through the connector 34. Since the output end of the vacuum collection pump 32 is connected to the collection box 31 through the delivery pipe 36, the vacuum collection pump 32 can provide adsorption power to the suction sleeve 35 through the hose 33 and the connector 34, enabling the suction sleeve 35 to suck the transverse row of the orifice plate at one time, thereby improving the efficiency of the device for sucking cell waste liquid from the orifice plate. Moreover, the vacuum collection pump 32 can convey the sucked waste liquid to the collection box 31, facilitating subsequent waste liquid treatment by the staff. Since the bottom end of the connector 34 is detachably connected to the suction sleeve 35, the user can disassemble and replace the suction sleeve 35 according to needs, and then replace the suction sleeve 35 after use to avoid cross-infection. Through the C-shaped frame 37, it can not only provide an installation basis for the vacuum collection pump 32 but also provide a placement space for the collection box 31. Since the bottom end of the delivery pipe 36 is connected to the collection box 31 in a conducting manner, the user can pull out the bottom end of the delivery pipe 36 from the collection box 31 to clean and maintain the collection box 31.

[0037] Refer to Figure 2 、 Figure 4 and Figure 5 As shown in, the support component 4 includes a second electric push rod 41. The bottom end of the second electric push rod 41 is connected to the top surface of the base 1. The telescopic end of the second electric push rod 41 is equipped with a stabilizing plate 42. One end of the stabilizing plate 42 is provided with a card slot 43 for clamping the suction sleeve 35. A distance sensor is arranged on the bottom surface of the stabilizing plate 42 at the inclined surface position, and a card holder 44 for clamping the hose 33 is arranged on the top surface of the stabilizing plate 42.

[0038] Through the stabilizing plate 42 in the support component 4, it can be installed on the top surface of the base 1 through the second electric push rod 41 and can also limit the suction sleeve 35 by clamping through the card slot 43, thereby providing a stable installation basis for the suction sleeve 35. Since a distance sensor is arranged on the bottom surface of the stabilizing plate 42 at the inclined surface position, through the distance sensor, in cooperation with the control component 5, the height of the telescopic movement of the second electric push rod 41 can be accurately controlled, and then the up and down movement position of the stabilizing plate 42 can be accurately controlled, so as to enable the suction sleeve 35 to accurately insert into the hole grooves in the orifice plates at different position heights, facilitating the suction of waste liquid by the suction sleeve 35.

[0039] Refer to Figure 1 、 Figure 6 As shown in, the control component 5 includes a protective box 51 and a box cover 52 arranged on the top surface of the protective box 51. The protective box 51 is arranged on one side of the top surface of the base 1; a circuit board 53 is arranged in the inner cavity of the protective box 51, and a control switch group 54 is arranged on the top surface of the box cover 52.

[0040] By controlling the protective box 51 and the box cover 52 in the control component 5, the circuit board 53 and the switch group 54 can be installed. And through the circuit board 53, it can not only receive the data information sent by the tilt sensor 27 and the distance sensor, but also control the operation of devices such as the electric linear slide 25, the first electric push rod 26, the vacuum collection pump 32, and the second electric push rod 41. By controlling the switch group 54, it is convenient for the staff to flexibly turn on or off the operation of the device.

[0041] During operation, first, the staff places the orifice plate containing the waste liquid at the designated position on the transfer component 2. Then, through the control component 5, the transfer component 2 can be controlled to operate, which can not only make the transfer component 2 move the orifice plate to directly below the suction end of the suction component 3, but also make the orifice plate in a tilted state of 30° - 45° under the adjustment of the transfer component 2. Then, through the control component 5, the suction component 3 and the support component 4 can be controlled to start. Next, through the support component 4, the position of the liquid suction end of the suction component 3 can be automatically adjusted, so that the liquid suction end of the suction component 3 can be inserted into the hole slots in the uppermost row of the orifice plate, and then the cell waste liquid in the hole slots can be sucked. When the waste liquid in the uppermost row is sucked up, at this time, the control component 5 can not only control the support component 4 to drive the liquid suction end of the suction component 3 to slightly move away from the orifice plate, but also control the transfer component 2 to operate, so that the orifice plate moves closer to the support component 4. Then, the support component 4 drives the liquid suction end of the suction component 3 to be inserted into the hole slots in the second row from the top of the orifice plate again, so that the suction component 3 sucks the cell waste liquid again. Repeating the above operations, the collection of the cell waste liquid on the orifice plate is completed, improving the collection efficiency of the entire cell waste liquid and reducing the working intensity.

[0042] Through the U-shaped frame 21 in the transfer component 2, it can not only insert and install the two shaft rods 23 on the loading rack 22 through the two shaft holes 24, but also install and fix the first electric push rod 26, and at the same time, it can also be installed on the output end of the electric linear slide 25 located on the base 1. Since the tilt sensor 27 is arranged in the middle of the bottom surface of the loading rack 22, through the electric linear slide 25, the loading rack 22 equipped with the orifice plate can be driven to move through the U-shaped frame 21, and it can also be driven by the first electric push rod 26 to drive the loading rack 22 to rotate around the shaft rod 23 as the axis, so as to be able to adjust the tilt position of the loading rack 22 and the orifice plate. And under the action of the tilt sensor 27, the orifice plate can be in a specified tilt angle to facilitate the suction of the cell waste liquid by the suction component 3. Since sliders 28 are arranged on both sides of the bottom surface of the U-shaped frame 21, and slide rails 29 for guiding the sliders 28 are arranged on both sides of the top surface of the base 1, the smoothness of the reciprocating movement of the U-shaped frame 21 can be ensured under the action of the sliders 28 and the slide rails 29.

[0043] Through the suction sleeve 35 in the suction component 3, it can be installed on the support component 4 and connected to the hose 33 at the suction end of the vacuum collection pump 32 through the connector 34. Since the output end of the vacuum collection pump 32 is connected to the collection box 31 through the delivery pipe 36, the vacuum collection pump 32 can provide adsorption power to the suction sleeve 35 through the hose 33 and the connector 34, enabling the suction sleeve 35 to suck the cells in the waste liquid on the orifice plate in a row at one time, thereby improving the efficiency of the device for sucking the cells in the waste liquid on the orifice plate. Moreover, the vacuum collection pump 32 can transport the sucked waste liquid to the collection box 31, facilitating the subsequent treatment of the waste liquid by the staff. Since the bottom end of the connector 34 is detachably connected to the suction sleeve 35, the user can disassemble and replace the suction sleeve 35 according to needs, and can replace the suction sleeve 35 after use to avoid cross-infection. Through the C-shaped frame 37, it can not only provide an installation base for the vacuum collection pump 32 but also provide a placement space for the collection box 31. Since the bottom end of the delivery pipe 36 is connected to the collection box 31, the user can pull out the bottom end of the delivery pipe 36 from the collection box 31 to clean and maintain the collection box 31.

[0044] Through the stabilizing plate 42 in the support component 4, it can be installed on the top surface of the base 1 through the second electric push rod 41 and can also engage and limit the suction sleeve 35 through the card slot 43, thereby providing a stable installation base for the suction sleeve 35. Since a distance sensor is provided on the bottom surface of the stabilizing plate 42 at the inclined surface position, through the distance sensor, in cooperation with the control component 5, the height of the telescopic movement of the second electric push rod 41 can be accurately controlled, and thus the up and down movement position of the stabilizing plate 42 can be accurately controlled, so that the suction sleeve 35 can be accurately inserted into the hole grooves in the orifice plates at different positions and heights, facilitating the suction of the waste liquid by the suction sleeve 35.

[0045] Through the protective box 51 and the box cover 52 in the control component 5, the circuit board 53 and the switch group 54 can be installed. And through the circuit board 53, it can not only receive the data information sent by the tilt sensor 27 and the distance sensor but also control the operation of devices such as the electric linear slide 25, the first electric push rod 26, the vacuum collection pump 32, and the second electric push rod 41. By controlling the switch group 54, it is convenient for the staff to flexibly turn on or off the operation of the device.

[0046] In summary, the device can quickly collect the cell waste liquid on the orifice plate, thereby improving the overall efficiency of collecting the cell waste liquid and reducing the working intensity.
