Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0043] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0044] Example 1

[0045] like Figs. 1-2 As shown in the figure, this utility model embodiment proposes an automatic disposable syringe operating device 5. The automatic disposable syringe operating device 5 includes a clamping mechanism and a driving mechanism. The clamping mechanism includes a first clamping component for clamping the body of the disposable syringe 511 and a second clamping component for clamping the plunger of the disposable syringe 511. The first clamping component and the second clamping component work together to realize the rapid clamping and automatic replacement of the disposable syringe 511. The driving mechanism is connected to the second clamping component and is used to drive the second clamping component to move linearly in the vertical direction, thereby enabling the disposable syringe 511 to perform automatic liquid aspiration, rubber stopper puncture, and liquid drainage operations.

[0046] In the embodiment, the first clamping assembly includes a fixed plate 501 and an injection bottle clamping electric claw 506 arranged at the lower end of the fixed plate 501. The fixed plate 501 is the base component of the first clamping assembly, which supports the entire clamping assembly and connects with other components, and provides a mounting position for the injection bottle clamping electric claw 506 and other components. The injection bottle clamping electric claw 506 adopts a standard electric claw structure, and the specific structure of the driving motor and control circuit thereof belongs to the common means of the person skilled in the art, which will not be described in detail.

[0047] The injection bottle clamping electric claw 506 is provided with a first injection bottle clamping block 509 and a second injection bottle clamping block 510 arranged opposite to each other, and a clamping space for accommodating the shoulder of the disposable syringe 511 is formed between the two clamping blocks.

The first push rod clamping block 507 and the second push rod clamping block 508 are driven by the push rod clamping electric claw 505 to move towards each other to clamp the push rod of the disposable syringe 511. The clamping surface of the push rod clamping block is designed with a groove matched with the shape of the end of the push rod of the disposable syringe 511, so as to ensure the stability of clamping.

In the Y-direction, the output shaft of the speed reducer is connected with the driving wheel of the Y-direction synchronous belt transmission mechanism through a keyless shaft bushing, and the servo motor provides high-precision and stable power for the synchronous wheel through the output shaft of the speed reducer. The slider on the Y-direction linear guide rail is connected with the Z-direction linear module 504 through bolts, and the mechanical arm drives the Z-direction linear module 504 to move in the Y-direction.

[0057] In the embodiment, the storage system comprises a centrifugal tube placing rack 6, a waste box 7, an operation station 12, a disposable syringe placing rack 8 and a syringe bottle placing rack 9 arranged in sequence on the workbench.

[0058] Specifically, the centrifuge tube rack 6 is used to place centrifuge tubes, which is usually optimized according to the size and shape of the centrifuge tubes to ensure that the centrifuge tubes can be stably placed on the rack without tilting or rolling. During the sample processing, the position of the centrifuge tube rack 6 is set so that the mechanical arm can easily grab and place the centrifuge tubes, realizing automated processing.

[0059] In this embodiment, the automatic suction, rubber plug puncture and liquid discharge of the disposable syringe automatic operation device are all completed at the operation station 12. The centrifuge tube grabbing mechanical arm 3 grabs and places the centrifuge tube or syringe at the operation station 12, and the disposable syringe grabbing mechanical arm 4 moves the disposable syringe 511 to the operation station 12 to perform the related operation, so that various operations are concentrated at the operation station 12, making the operation process more coherent and efficient.

[0060] The waste box 7 is used to collect waste, which can keep the workbench clean and hygienic, reduce the pollution of waste to the working environment, and also facilitate the subsequent waste treatment and cleaning work.

The industrial computer 11 adopts a touch-type human-machine interface. An operator can monitor the running state of the equipment in real time through the interface and make parameter settings and handle exceptions. Since the diameter range of the rubber plug is generally 5 mm, the visual positioning sensor is used to realize the accurate alignment of the disposable syringe 511 and the rubber plug of the injection bottle before the rubber plug is punctured.

[0065] The working principle of the present application is described in detail in combination with Embodiment 1 and Embodiment 2 as follows:

[0066] The centrifugal tube clamping mechanical arm 3 moves to the specified position of the centrifugal tube rack 6 under the cooperation of the X-direction transmission component 13 and the first Y-direction transmission component 17. After the position of the centrifugal tube is confirmed by the visual positioning system, the Z-direction linear module 504 drives the cap screwing module 2 to descend, clamps the centrifugal tube and places it on the operation station 12. Then, the cap screwing module 2 performs the cap opening action and carries the centrifugal tube cap back to the initial position.

The needle of the disposable syringe 511 is accurately located in the centrifugal tube. The push rod clamping assembly is driven by the ball screw transmission assembly to move upward, so as to realize the accurate suction of the culture medium.

[0069] The centrifugal tube clamping mechanical arm 3 carries the centrifugal tube cover to the operation station 12, carries out the cover cover operation, and places the covered centrifugal tube on the centrifugal tube rack. Subsequently, the centrifugal tube clamping mechanical arm 3 clamps the injection bottle to the operation station 12, the disposable syringe clamping mechanical arm 4 carries the disposable syringe 511 for sucking culture medium to above the injection bottle, confirms the position through the visual positioning sensor, slowly lowers the disposable syringe 511 through the Z-direction linear module 504, makes the needle of the disposable syringe 511 accurately puncture the rubber plug of the injection bottle, drives the push rod clamping assembly downward through the ball screw driving assembly, and pours the culture medium into the injection bottle.
