In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0029] Combine the following Figure 1-Figure 4The utility model is described as an intelligent syringe aspiration device, comprising a platform seat 10 and a displacement assembly 20, wherein the platform seat 10 is provided with a test tube support 30 and a positioning support 40, wherein the test tube support 30 is provided with at least one test tube fixing station 34, and the positioning support 40 is provided with a syringe fixing station 41, and the test tube fixing station 34 and the syringe fixing station 41 are in the same line; the displacement assembly 20 is arranged above the platform seat 10, and the displacement assembly 20 comprises a translation slide 21, a sliding component 22, a lifting slide 23 and a lifting component 24, wherein the sliding component 22 is slidably arranged on the translation slide 21, and the lifting slide 23 and the lifting component 24 are provided. The descending slide 23 is fixedly arranged on the sliding component 22, and the lifting component 24 is slidably arranged on the lifting slide 23; wherein, the lifting component 24 includes a claw clamp structure 25 and a servo push rod 26 for grasping the syringe, the claw clamp structure 25 is connected to the servo push rod 26, so that the servo push rod 26 pushes the claw clamp structure 25 to realize the liquid aspiration operation of the syringe, the claw clamp structure 25 is located directly above the test tube fixing station 34 and the syringe fixing station 41, and the axis of the translation slide 21 and the axis of the test tube fixing station 34 and the syringe fixing station 41 are parallel on the same projection plane. When the syringe is aspirating and sampling, it is necessary to pull the piston shaft of the syringe to realize the absorption of the solution. In this embodiment, the syringe is grasped by the claw clamp structure 25, and the liquid aspiration operation can be realized by the servo push rod 26 after grasping, realizing the automatic liquid aspiration operation, improving the degree of automation, and realizing quantitative operation through automatic control, improving reliability and consistency.

[0030] It can be understood that a test tube support 30 and a positioning support 40 are provided on the platform base 10. The test tube fixing station 34 on the test tube support 30 is used to fix the test tube, and a syringe fixing station 41 for fixing the syringe is correspondingly provided on the positioning support 40. The empty syringe is transferred to the positioning support 40 through an external device, and then the claw clamp can grab the empty syringe and move it to the designated test tube position to realize the liquid aspiration operation. After the liquid aspiration is completed, it is transferred to the predetermined position through an external device to complete the entire liquid aspiration operation.

[0031] In the specific setting, the positioning support 40 includes a cylindrical support body, a positioning hole is provided in the middle of the support body, and a flexible covering member is provided around the edge of the positioning hole. The syringe is inserted into the positioning hole, and the positioning hole is used to achieve centering and positioning, which is convenient for the transfer of external equipment and the grasping of the claw structure 25. Specifically, the external equipment is a manipulator, and the manipulator has a certain deviation when positioning at the destination, which makes it impossible to ensure stability and accuracy if the manipulator is directly docked with the claw structure 25. In this embodiment, through the setting of the positioning support 40, the positioning support 40 can achieve accurate positioning, which improves the stability and accuracy of the syringe during the handover and transfer.

[0032] Among them, the translation slide 21 can make the sliding component 22 move along a straight line. In order to simplify the control logic and simplify the specific implementation structure of the equipment, in this embodiment, the test tube fixing station 34 and the syringe fixing station 41 are limited to the same straight line, and the straight line is made parallel to the translation slide 21. Further, by setting the claw clamp mechanism directly above the test tube fixing station 34 and the syringe fixing station 41, the linear movement of the sliding component 22 can be used to operate on different test tube fixing stations 34, thereby simplifying the operation process and making the overall operation more stable and accurate.

[0033] The specific process is as follows: first, the empty syringe is transferred to the positioning support 40 by the manipulator, and the positioning support 40 realizes the positioning of the syringe, and then the sliding component 22 is controlled to slide along the translation slide 21, and stops sliding after sliding to the position corresponding to the positioning support 40, and the lifting component 24 is controlled to descend. After descending to the predetermined position, the servo push rod 26 is controlled to move, and the claw clamp structure 25 is driven to descend. The claw clamp structure 25 descends to the specified position and realizes the grabbing of the syringe. After the grabbing is successful, it rises to the specified position through the servo push rod 26, and slides to the specified test tube position through the sliding component 22 to perform the liquid aspiration operation. After the washing operation is completed, it is moved to the position of the positioning support 40 to place the syringe with the solution, and then transferred by the manipulator.

[0034] According to an embodiment provided by the utility model, the claw clamp structure 25 includes a first claw clamp 251 and a second claw clamp 252. The first claw clamp 251 is spaced apart from the second claw frame. The first claw clamp 251 is used to grab the empty barrel part of the syringe, and the second claw clamp 252 is used to grab the piston shaft part of the syringe. The key components of the syringe include the empty barrel part and the piston shaft part. The piston shaft part is inserted into the empty barrel part. By pulling the piston shaft, negative pressure is generated in the empty barrel to achieve the absorption of the solution. In this embodiment, the liquid absorption operation is achieved by two claw clamps, which can cooperate well with conventional syringes to absorb liquid, thereby improving the stability of the lotion and the accuracy of the amount of liquid absorbed.

[0035] It can be understood that the first claw clamp 251 is used to grasp the empty barrel part, which can fix the empty barrel part, and the second claw clamp 252 cooperates with the piston shaft part of the syringe, so that it can drive the piston shaft to move to achieve the liquid suction operation.

[0036] In the specific configuration, the lifting component 24 further includes a connection seat, which is slidably connected to the lifting slide 23, a first claw clamp 251 is arranged at the bottom of the connection seat, a servo push rod 26 is arranged at the top of the connection seat, and a second claw clamp 252 is arranged on the servo push rod 26. Usually, the maximum and minimum distances between the empty barrel part and the piston shaft part of the syringe have standard reference values. In this embodiment, the first claw clamp 251 and the second claw clamp 252 brackets are arranged at intervals, and the second claw clamp 252 is connected to the servo push rod 26, so the spacing between the empty barrel part and the piston shaft part of the syringe can be adjusted so that they can align with the corresponding parts when grasping, so as to achieve accurate grasping and accurate pulling.

[0037] It can be understood that the servo push rod 26 includes a servo drive motor and a push rod, the push rod is connected to the servo drive motor, and the servo drive motor can accurately control the extension and retraction amount of the push rod, thereby achieving precise control of the amount of liquid sucked, and improving the accuracy of liquid sucking.

[0038] In the specific setting, the connecting seat includes at least two plates, the first plate is used to be slidably connected to the lifting slide 23, and the second plate is used to be fixedly connected to the first plate. The first plate serves as the main part of the connecting seat, which is extended in the vertical direction. The servo push rod 26 is connected to the top of the first plate and extends the push rod downward. The first claw clamp 251 is connected to the push rod and follows the telescopic movement of the push rod.

[0039] In a specific application, the first claw clamp 251 and the second claw clamp 252 both include a claw hand and a driving part, the claw hand is connected to the driving part, and the driving part drives the claw hand to open or close. The difference between the first claw clamp 251 and the second claw clamp 252 is that the first claw clamp 251 is opened and closed horizontally, and the second claw clamp 252 is clamped and closed vertically.

[0040] According to the specific implementation provided by the utility model, a translation servo motor is provided on one end of the translation slide 21, and the translation servo motor is used to drive the sliding component 22 to move along the translation slide 21. The sliding component 22 needs to correspond to the test tube fixing station 34 and the syringe fixing station 41 during the sliding process, that is, it needs to be positioned on the translation slide 21. In this embodiment, the movement amount of the sliding component 22 is limited by the drive of the servo motor, thereby improving the accuracy of positioning.

[0041] Similarly, a lifting servo motor is provided on the top of the lifting slide 23, and the lifting servo motor is used to drive the lifting component 24 to move along the lifting slide 23. The lifting slide 23 also needs to be positioned during the lifting process, so the positioning accuracy can be improved by the lifting servo motor.

[0042] In the specific configuration, the sliding component 22 is connected to the translation servo motor through a screw transmission component, and the lifting component 24 is connected to the lifting servo motor through a screw transmission component, and the respective transmissions are realized by means of the screw transmission component.

[0043] In a specific implementation, both ends of the translation slide 21 are provided with limit blocks 211. The setting of the limit blocks 211 can realize the accurate positioning of the sliding component 22 and prevent the sliding component 22 from sliding out of the translation slide 21.

[0044] In some embodiments, the sliding component 22 includes a support seat, and the lifting slide 23 is fixedly arranged on the support seat. The support seat is slidably connected to the translation slide 21. The support seat, as the main supporting component, can drive the lifting slide 23 and various components connected to the lifting slide 23 to move as a whole to achieve horizontal displacement.

[0045] According to an embodiment of the present invention, there are multiple test tube supports 30, which are arranged in a straight line and at intervals, and positioning supports 40 are provided between adjacent test tube supports 30. When large-scale sampling is required, it is necessary to improve the overall sampling efficiency. In this embodiment, multiple test tube fixing stations 34 can be arranged on the platform seat 10 by means of multiple test tube supports 30, thereby achieving efficiency improvement, and the sampling efficiency is further improved by providing positioning supports 40 between adjacent test tube supports 30.

[0046] It is understandable that during the syringe transfer process and the test tube replacement process, operation needs to be performed through external equipment, which takes a certain amount of time to complete the transfer. In this embodiment, by means of multiple test tube supports 30 and multiple positioning supports 40, the time during the syringe transfer process and the replacement process can be utilized, thereby improving the sampling efficiency.

[0047] In the specific configuration, each test tube support 30 is provided with a plurality of test tube fixing stations 34, and the plurality of test tube fixing stations 34 are arranged linearly and spaced apart. The configuration of the plurality of test tube fixing stations 34 on each test tube support 30 can further improve the sampling efficiency and realize efficient sampling.

[0048] When applying specific Figure 1 , Figure 2 As shown, two test tube supports 30 are provided on the platform seat 10, a positioning support 40 is provided between the two test tube supports 30, four test tube fixing stations 34 are provided on each test tube support 30, and a syringe fixing station 41 is provided on the positioning support 40. In this way, the sampling efficiency can be improved and efficient batch sampling can be achieved.

[0049] like Figure 2As shown, in some embodiments, the test tube support 30 includes a first horizontal plate 31, a second horizontal plate 32 and a third horizontal plate 33 arranged in sequence along the vertical direction, and the first horizontal plate 31, the second horizontal plate 32 and the third horizontal plate 33 are connected to side plates on both sides, the first horizontal plate 31 is fixedly arranged on the platform seat 10, and the second horizontal plate 32 and the third horizontal plate 33 are provided with fixing holes 36 for fixing the test tube, and the first horizontal plate 31 corresponding to the fixing holes 36 is provided with a bottom bracket 35, and the bottom bracket 35 is used to contact the bottom of the test tube. During the sampling process, the test tube needs to be kept stable. In this embodiment, a spaced layer structure is formed by a plurality of horizontal plates, which improves the stability of the test tube fixation.

[0050] It is understandable that at least two positioning surfaces can be realized on each test tube through the second horizontal plate 32 and the third horizontal plate 33, so that the test tube can be kept in a straight and stable state, thereby improving stability. In addition, the setting of the bottom bracket 35 can protect the test tube from being damaged during the installation process, thereby protecting the safety of the test tube.

[0051] like Figure 3 As shown, in a specific example, a flexible fitting portion is provided around the edge of the fixing hole 36. The provision of the flexible fitting portion can improve the stability of the test tube on the one hand, and prevent the test tube from being damaged during installation and operation on the other hand.

[0052] It is understandable that test tubes are usually made of glass, which is easily broken. In this example, the flexible fitting portion is provided so that it can be squeezed and deformed to improve its stability, and the flexible material can be used to reduce vibration during assembly and operation, thereby protecting the test tube.

[0053] Through the description of the above embodiments, those skilled in the art can clearly understand that in each embodiment, the platform seat 10 and the displacement assembly 20 cooperate to enable the claw clamp on the displacement assembly 20 to grasp the syringe, and the syringe can be pulled by the movement of the displacement assembly 20, thereby realizing automatic liquid aspiration, and quantitative liquid aspiration can be realized by controlling the displacement of the lifting component 24, providing a high degree of automation, reliability and accuracy. Furthermore, the setting of multiple test tube fixing stations 34 can improve the sampling efficiency and realize efficient processing of batch sampling.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
