[0001] The present invention relates to the technical field of serum detection, in particular to an automatic liquid adding and oscillating device, and also relates to a serum detector including the above automatic liquid adding and oscillating device. Background Art

[0002] The principle of serum detection is based on the agglutination reaction of antigen and antibody, and the agglutination state is observed manually or detected by an instrument to judge the experimental result. The methods adopted manually include the test tube method and the slide method. The accuracy of observation depends on the accumulation of experience and the accuracy of the processing process. For weak agglutination reactions, other tools (such as a microscope) are also required for judgment; in order to improve the detection efficiency, serum detection instruments that can detect quickly have emerged on the market currently;

[0003] Existing serum detection instruments mainly include an oscillating and mixing device, an oscillation box, a centrifuge tube and a manipulator. The oscillation box is used to carry the centrifuge tube (culture plate / culture dish). The centrifuge tube is filled with a sample solution. The oscillation box is directly configured on the oscillating and mixing device. When in use, the manipulator is responsible for grasping the centrifuge tube into the oscillation box, and the oscillating and mixing device drives the oscillation box and the centrifuge tube thereon to oscillate to improve the detection efficiency; the main defects of such a serum detection instrument are as follows: the oscillating and mixing device has a complex structure and high cost, and it is difficult or impossible to adjust the oscillation amplitude; secondly, since a manipulator is required to grasp the centrifuge tube, the complexity of the structure is further increased, and at the same time, the floor area is also increased.

[0049] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present invention. Therefore, they only show the components related to the present invention. Directions and references (such as up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following detailed implementation mode is not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0050] As Figures 1-6 shown, an automatic liquid adding and oscillating device includes a frame 1, an elastic supporting component 5, an X-axis moving component 2, a stack 8, a Z-axis moving component 4, a liquid supply mechanism 6 and a cam component 7; in this embodiment, the X-axis direction, Y-axis direction and Z-axis direction can be perpendicular to each other, constituting a three-dimensional rectangular coordinate system;

[0051] The elastic supporting component 5 includes a tray 5-1 and an elastic shrapnel 5-2. The material of the shrapnel 5-2 can be, but is not limited to, metal;

[0052] The X-axis moving component 2 is installed on the frame 1. The X-axis moving component 2 can be, but is not limited to, an electric slide table, an electric push rod, a cylinder, etc. Taking the X-axis moving component 2 as an electric slide table as an example, the X-axis moving component 2 using the electric slide table is fixedly installed on the frame 1. The X-axis output end 2-1 of the X-axis moving component 2 is fixedly connected to one end of the shrapnel 5-2, and the other end of the shrapnel 5-2 is fixedly connected to the tray 5-1, so that the shrapnel 5-2 is elastically connected to the tray 5-1 and can support the tray 5-1; The X-axis moving component 2 is used to drive the tray 5-1 to move along the X-axis direction through the shrapnel 5-2, so that the tray 5-1 can at least switch between the material taking station, the liquid adding station and the vibration station. The liquid adding station can be specifically located between the material taking station and the vibration station;

[0053] The stack 8 is used to store a plurality of culture plates 9. The culture plate 9 has a culture groove 9-1 for accommodating the specimen liquid. The specimen liquid can be, but is not limited to, serum;

[0054] The Z-axis moving component 4 is installed on the frame 1. The Z-axis moving component 4 can be, but is not limited to, an electric slide table, an electric push rod, a cylinder, etc. Taking the Z-axis moving component 4 as an electric slide table as an example, the Z-axis moving component 4 using the electric slide table is fixedly installed on the frame 1. The Z-axis moving component 4 is used to make the tray 5-1 at the material taking station pick up the culture plate 9 on the stack 8;

[0055] The liquid supply mechanism 6 is used to add the test liquid to the culture groove 9-1 on the tray 5-1 at the liquid adding station. The test liquid can be determined according to the adjustment of the sample liquid. For example, when the sample liquid is serum, the test liquid corresponds to the test reagent for serum detection;

[0056] The cam component 7 has a motor 7-1 and a cam 7-2. The motor 7-1 is used to drive the cam 7-2 to rotate. The X-axis moving component 2 is also used to adjust the relative position between the tray 5-1 at the vibration station and the cam 7-2 along the X-axis direction, so that when the cam 7-2 rotates, the cam 7-2 collides with the elastic supporting component 5.

[0057] This automatic liquid adding and oscillating device can not only use the X-axis moving component 2 to drive the tray 5-1 to switch between the material taking station, the liquid adding station and the vibration station, but also use the X-axis moving component 2 to change the distance between the cam 7-2 and the tray 5-1. After adjusting the distance, the motor 7-1 drives the cam 7-2 to rotate, and the cam 7-2 intermittently collides with the elastic supporting component 5, so that the oscillation amplitude of the tray 5-1 can be simply and quickly changed, which is beneficial to the sample liquid to be in the best oscillation amplitude, improving the detection effect and detection efficiency.

[0058] As an example, such asFigure 9 As shown, the upper surface of the elastic piece 5-2 is a narrow surface 5-2a. The two relatively arranged wide surfaces 5-2b of the elastic piece 5-2 are spaced apart in the X-axis direction and are located on both sides of the narrow surface 5-2a. The positive projection of the wide surface 5-2b on the projection plane perpendicular to the X-axis direction is the first projection, and the positive projection of the narrow surface 5-2a in the horizontal plane is the second projection. The area of the first projection > the area of the second projection; that is, the elastic piece 5-2 is not prone to elastic deformation in the up and down direction, but is prone to elastic deformation in the X-axis direction. In this way, the elastic piece 5-2 can firmly support the tray 5-1 in the up and down direction, preventing the tray 5-1 from tilting up and down under non-vibrating conditions, and is used to cooperate with the cam 7-2 to elastically deform in the X-axis direction to improve the vibration effect of the tray 5-1.

[0059] As an example, as Figures 7-10 shown, the elastic supporting component 5 further includes a spacer block 5-3 and a traction block 5-4. The spacer block 5-3 is located at the middle part of the side surface of the tray 5-1 close to the cam 7-2 and is fixedly connected to the tray 5-1, which can improve the uniformity of the vibration of the tray 5-1. The traction block 5-4 and the spacer block 5-3 can be specifically fixedly connected by screws. The elastic piece 5-2 is clamped and fixed between the traction block 5-4 and the spacer block 5-3; the traction block 5-4 can be, but is not limited to, an L-shaped traction block 5-4. For example, the L-shaped traction block 5-4 includes a horizontal section and a vertical section connected to each other. The vertical section extends in the X-axis direction, and the horizontal section and the vertical section are arranged at approximately 90°. The elastic piece 5-2 is correspondingly clamped and fixed between the horizontal section of the traction block 5-4 and the spacer block 5-3, and the vertical section is for the cam 7-2 to collide with to cause the tray 5-1 to vibrate, and the spacer block 5-3 can keep a certain gap between the tray 5-1 and the elastic piece 5-2 to improve the vibration effect.

[0060] As an example, as Figure 3 and 4 shown, the motor 7-1 is fixed on the frame 1, and the cam 7-2 is fixedly connected to the main shaft of the motor 7-1, so that the motor 7-1 directly drives the cam 7-2 to rotate. The rotation axis of the cam 7-2 is substantially parallel to the Y-axis direction.

[0061] As an example, as Figure 1 and 5 shown, a plurality of culture plates 9 are spaced apart in the Z-axis direction on the stack 8. The Z-axis direction is the up and down direction and is perpendicular to the X-axis direction. In the stack 8 of this embodiment, there are a plurality of layers of support block groups spaced apart in the Z-axis direction. The support blocks in the same layer of support block groups have the same height, and each layer of support block groups is used to independently support the culture plate 9;

[0062] The Z-axis output end 4-1 of the Z-axis moving component 4 is fixedly connected to the stack 8. The Z-axis moving component 4 is used to drive the stack 8 to move along the Z-axis direction, so that the tray 5-1 at the material taking station can pick up the culture plate 9 on the stack 8. When the Z-axis moving component 4 works, the Z-axis output end 4-1 rises or falls along the Z-axis direction. During the process of the Z-axis output end 4-1 falling, the culture plate 9 on the support block group of the stack 8 can fall onto the tray 5-1, and the tray 5-1 supports the culture plate 9 instead. During the process of the Z-axis output end 4-1 rising, the culture plate 9 on the tray 5-1 can return to the stack 8 again and is supported by a layer of support block group on the stack 8.

[0063] As an example, a number of rows of culture trough groups are distributed along the Y-axis direction on the culture plate 9, and a number of culture troughs 9-1 are spaced along the X-axis direction in each row of culture trough groups, which is equivalent to that a number of culture troughs 9-1 are arrayed on the culture plate 9;

[0064] The liquid supply mechanism 6 includes a liquid supply pump 6-1 and a needle seat plate 6-2. A number of needle holes 6-21 are spaced along the X-axis direction on the needle seat plate 6-2. The mouth of the culture trough 9-1 faces upward, and the lower opening of the needle hole 6-21 is located above the culture trough 9-1 on the tray 5-1 at the liquid adding station. The liquid supply pump 6-1 is used to pump the test liquid into the needle holes 6-21. Specifically, the liquid supply pump 6-1 can be a peristaltic pump. The inlet of the liquid supply pump 6-1 is connected to the container storing the test liquid through a pipeline, and the outlet of the liquid supply pump 6-1 is connected to the needle holes 6-21 through a pipeline;

[0065] The Y-axis moving component 3 is further arranged on the frame 1. The Y-axis moving component 3 can be but is not limited to an electric slide table, an electric push rod, a cylinder, etc. Taking the Y-axis moving component 3 as an electric slide table as an example, the Y-axis moving component 3 using the electric slide table is fixedly installed on the frame 1. The Y-axis output end 3-1 of the Y-axis moving component 3 is fixedly connected to the needle seat plate 6-2. The Y-axis moving component 3 is used to drive the needle seat plate 6-2 to move along the Y-axis direction;

[0066] In this embodiment, the Y-axis moving component 3 can drive the needle seat plate 6-2 to reach directly above each row of culture trough groups. When the needle seat plate 6-2 reaches directly above a row of culture trough groups, the needle holes 6-21 on the needle seat plate 6-2 are respectively directly opposite to the culture troughs 9-1 in this row of culture trough groups, and the test liquid in the needle holes 6-21 will drip into the culture troughs 9-1 directly below them, so as to realize batch liquid addition.

[0067] As an example, such as Figure 1As shown, an industrial camera 10 for capturing image information of the culture tank 9-1 is also fixed on the Y-axis output end 3-1. The industrial camera 10 is specifically located above the culture plate 9 held by the tray 5-1. The tray 5-1 can also be a structure with a hollow middle. A lighting device is arranged below the tray 5-1, and the light of the lighting device passes through the hollow structure in the middle of the tray 5-1 to improve the shooting effect of the industrial camera 10. All captured image information can be directly transmitted to the connected computer for analysis.

[0068] As an example, as Figure 1 shown, a liquid receiving groove 11 with an upward notch is arranged on the side of the tray 5-1 on the frame 1. The liquid receiving groove 11 is located on the moving path of the needle seat plate 6-2 and below the lower opening of the needle hole 6-21. The Y-axis moving component 3 can move the needle seat plate 6-2 above the liquid receiving groove 11, and the residual test liquid in the needle hole 6-21 will drip into the liquid receiving groove 11 for collection, preventing the residual test liquid in the needle hole 6-21 from dripping onto other parts and affecting the test environment.

[0069] When the above X-axis moving component 2 works, the X-axis output end 2-1 reciprocates along the X-axis direction; when the Y-axis moving component 3 works, the Y-axis output end 3-1 reciprocates along the Y-axis direction; when the Z-axis moving component 4 works, the Z-axis output end 4-1 reciprocates along the Y-axis direction.

[0070] The detailed working process of the automatic liquid adding and oscillating device in the above embodiment is as follows:

[0071] 1). A plurality of culture plates 9 are pre-installed in the stack 8 along the axis direction, and the culture tanks 9-1 of each culture plate 9 are filled with serum to be detected.

[0072] 2). The X-axis moving component 2 drives the tray 5-1 to move backward along the X-axis direction into the stack 8 and is located below the culture plate 9 to be detected. At this time, the tray 5-1 reaches the material taking station. Subsequently, the Z-axis moving component 4 drives the stack 8 to descend, and a culture plate 9 to be detected will fall onto the tray 5-1 to complete the material taking.

[0073] 3). Subsequently, the X-axis moving component 2 drives the tray 5-1 carrying the culture plate 9 to move forward along the X-axis direction to the liquid adding station. Then, the Y-axis moving component 3 can drive the needle seat plate 6-2 to reach directly above each row of culture tank groups. When the needle seat plate 6-2 reaches directly above a row of culture tank groups, the needle holes 6-21 on the needle seat plate 6-2 are respectively directly opposite to the culture tanks 9-1 in this row of culture tank groups. At the same time, the liquid supply pump 6-1 is started to convey the test liquid into the needle holes 6-21, and the test liquid in the needle holes 6-21 will drip into the culture tanks 9-1 directly below it to finally complete the addition of the test liquid into the serum in each culture tank 9-1.

[0074] 4), Next, the X-axis moving component 2 drives the tray 5-1 to move forward along the X-axis direction to the vibration station, and determines the distance between the traction block 5-4 and the cam 7-2. For example, the tray 5-1 moves to a position where the traction block 5-4 is 1 mm away from the base circle of the cam 7-2. Then, the motor 7-1 drives the cam 7-2 to rotate, and the cam 7-2 intermittently collides with the traction block 5-4 to drive the tray 5-1 to oscillate. The culture plate 9 on the tray 5-1 also oscillates accordingly to promote the dispersion of the test solution in the serum in the culture tank 9-1, thereby promoting the reaction between the test solution and the serum;

[0075] 5), Next, the X-axis moving component 2 drives the tray 5-1 to move backward along the X-axis direction to the liquid adding station and stands for a corresponding time. Then, the Y-axis moving component 3 drives the industrial camera 10 to move along the Y-axis direction and respectively aligns with the serum in the culture tank 9-1 on the culture plate 9 for shooting. After the shooting is completed, the industrial camera 10 returns to the previous position, and all the captured image information can be directly transmitted to the connected computer for analysis;

[0076] 6), Finally, the X-axis moving component 2 drives the tray 5-1 to move backward along the X-axis direction into the stack 8, and the Z-axis moving component 4 drives the stack 8 to rise. The culture plate 9 that has completed the detection on the tray 5-1 will return to the stack 8 again.

[0077] As an example, a serum detector includes the automatic liquid adding and oscillating device in the above embodiment.
