Description

Technical Field

[0001] The invention relates to an experimental auxiliary equipment, in particular to an electric manual sample adding gun and a sample adding device with traceable sample adding information. Background Art

[0002] In daily experiments, there are many cases where the experimental results are quite different from the expected or theoretical results. Many of these cases are caused by incorrect or inaccurate addition of liquid. Common sample guns on the market are manual and electric. For manual sample guns, the sample rod is directly pressed to control the piston for sample addition. The sample addition accuracy is not high and the operation experience is not good. For electric sample guns, the function key is directly pressed to add liquid. There is no feel of operation for adding liquid, which is easy to cause errors in adding liquid.

[0003] In view of the shortcomings of common manual and electric sample adding guns in the market, the applicant has proposed a patented technical solution for an electric manual sample adding device, see the patent document with the authorization announcement number CN107597222B for details, the electric manual sample adding device manually operates the sample adding control rod, and the electric control motor controls the piston to add samples, avoiding the operation of fast beating and fast suction, while improving the user's experience of small volume sample adding using the manual sample adding device, and improving the sample adding accuracy. In addition, regardless of the size of the sample adding volume, the sample adding control rod stroke remains unchanged, and the user can maintain the same operating feel. However, the above patented solution cannot completely eliminate the occurrence of sample adding errors. Since the existing sample adding guns do not have the liquid adding traceability function, it cannot be ruled out whether the difference in experimental results is caused by sample adding errors, so the experiment can only be redone, resulting in a large waste of time. In addition, the patented technical solution proposed by the applicant first, although it can improve the sample adding accuracy and maintain the sample adding feel, it still requires the operator to have a skilled sample adding operation technique to give full play to its greatest advantage, so how to facilitate novices to practice and correct errors has also become the direction of the applicant's continued research. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide an electric manual sample adding gun and a sample adding device with traceable sample adding information.

[0005] In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problem is:

[0006] An electric manual sample adding gun with traceable sample adding information, comprising a shell body, a sample adding control rod located on the top of the shell body, and a spring connected to the sample adding control rod;

[0007] It also includes a sample addition adjustment knob, which is used to set the liquid addition volume;

[0008] The housing body is provided with a piston module, a detection module, a processing module, a storage module, an information transmission module and a power supply module; the detection module is connected to the processing module, and the processing module is connected to the piston module, the storage module, the information transmission module and the power supply module;

[0009] The piston module comprises a piston and a motor, and the motor drives the piston to move via a transmission member;

[0010] The detection module is used to detect the movement stroke, speed and acceleration of the sample loading control rod and the sample loading adjustment knob;

[0011] The processing module receives the movement information of the sample loading control rod and the sample loading adjustment knob detected by the detection module, and sends a command signal to control the action of the motor after processing;

[0012] The storage module is used to store the sample addition order, the liquid addition volume set by the sample addition adjustment knob, the movement stroke / speed / acceleration of the sample addition control rod, and the actual liquid addition volume information data converted from the motor rotation information;

[0013] The information transmission module is used to communicate with an external terminal so that the external terminal can obtain the information data stored in the storage module.

[0014] By adopting the technical solution of the present invention, a storage module is integrated on the electric manual sample adding gun to save the sample adding information. When the sample adding data needs to be queried, the stored data is directly retrieved, and the information such as the originally set liquid adding volume, whether the operation of the sample adding control lever is normal, and the actual liquid adding amount can be traced back. It can be determined whether the original sample adding is abnormal, which is convenient for quickly tracing the root cause of the problem and reducing unnecessary repeated experiments.

[0015] Furthermore, the processing module is preset with a standard speed range for determining whether the action of the sample addition control rod belongs to normal operation, and the standard speed range is composed of a speed reference value and an allowable deviation value;

[0016] When the actual speed of the sample loading control rod is within the standard speed range, the processing module controls the speed of the motor according to the actual speed of the sample loading control rod, and the piston movement speed corresponding to the motor speed is in direct proportion to the actual speed of the sample loading control rod;

[0017] When the actual speed of the sample addition control rod exceeds the standard speed range, the processing module corrects and adjusts the motor speed and completes the sample addition amount that is the same as the set liquid addition volume.

[0018] By adopting the above preferred solution, when the sample adding personnel do not use the sample adding gun normally, the error can be automatically corrected and the sample adding task can be completed.

[0019] Furthermore, in the full stroke of the sample loading control rod, the speed reference value at each stroke point is a variable value, and the standard speed range also changes with the speed reference value.

[0020] The above preferred solution is adopted to adapt to the perfect sample addition technique, which not only ensures the sample addition speed, but also reduces liquid dripping and improves the liquid addition accuracy.

[0021] Furthermore, it also includes a learning mode for collecting the speed reference value. In the learning mode, the speed value of the sample addition control rod over the full stroke is collected as the speed reference value.

[0022] By adopting the above preferred solution, the mode is convenient for skilled operators to input the best gun-using techniques and convenient for inputting appropriate speed reference values ​​for different use occasions. With the help of an external terminal, a standard gun-using speed curve can be output, which is convenient for teaching gun-using techniques, and beginners can also understand the differences in gun-using techniques more intuitively.

[0023] Furthermore, the detection module includes a first sensor for detecting the rotation angle, rotation speed and acceleration of the sample addition adjustment knob, and a second sensor for detecting the movement displacement, speed and acceleration of the sample addition control rod.

[0024] Furthermore, the changing speed of the sample addition amount value set by the sample addition adjustment knob is directly proportional to the rotation speed and acceleration detected by the first sensor.

[0025] By adopting the above-mentioned preferred scheme, for setting the amount of liquid added, the change speed of the set value can be matched according to the rotation speed detected by the first sensor, and the magnification factor of the set value corresponding to the unit rotation angle can be set by the rotation acceleration, so that the user can quickly and easily obtain the preset liquid addition volume value.

[0026] Furthermore, the detection module also includes a third sensor for detecting the movement displacement of the piston.

[0027] By adopting the above preferred solution, the actual amount of sample added can be obtained to correct the motor speed and improve the sample addition accuracy.

[0028] Furthermore, it also includes a display module, and the display module is signal-connected to the processing module.

[0029] By adopting the above preferred solution, the set sample addition amount and other information can be intuitively displayed through the display module.

[0030] Furthermore, the detection module also includes a direction sensor for detecting the posture of the sample adding gun, and the liquid adding angle information of the sample adding gun is obtained after being processed by the processing module and the liquid adding angle information of the sample adding gun is stored in the storage module.

[0031] By adopting the above preferred solution, it is convenient to trace the angle of the gun.

[0032] Furthermore, the detection module also includes a pressure sensor installed between the motor transmission member and the piston, and the processing module receives the pressure value information detected by the pressure sensor, and saves the pressure value into the storage module after processing.

[0033] By adopting the above preferred scheme, in different situations such as when the piston cylinder of the sampling gun is empty, when there are liquids of different viscosities, and when the gun tip is clogged, after the motor is actuated, the pressure values ​​obtained by the pressure sensor above the piston are different. The pressure detected by the pressure sensor can be used to obtain richer gun usage status, making it easier to trace the gun operation.

[0034] Furthermore, the processing module presets a plurality of sets of standard speed ranges with different range values, and the processing module selects a matching set of standard speed ranges to determine whether the action of the sample addition control lever is a normal operation according to the pressure value data detected by the pressure sensor.

[0035] By adopting the above preferred scheme, the concentration data of the added liquid can be understood by means of the pressure detected by the pressure sensor, so as to select the standard speed range matching the actual added liquid concentration to guide the gun action, further improving the intelligence of the sample adding gun and improving the final addition accuracy.

[0036] A sample adding device, comprising the above-mentioned electric manual sample adding gun with traceable sample adding information;

[0037] The external terminal includes a terminal controller, a terminal memory and a terminal display. The terminal memory and the terminal display are both connected to the terminal controller. The terminal controller reads the sample loading information data in the storage module of the electric manual sample loading gun and saves the data to the terminal memory. The obtained sample loading information data is used to generate a sample loading information chart on the terminal controller through software, and is displayed to the user through the terminal display.

[0038] By adopting the above technical solution, the sample addition data collected by the sample gun is processed through the external terminal, and the gun use history and gun use process status are more intuitively displayed, which facilitates the rapid tracing of the actual amount of liquid added in the experiment. It is also more convenient for sample gun beginners to intuitively understand the difference between their own gun use techniques and standard techniques, and can quickly explore the tricks of gun use, quickly master gun use skills, and improve the precision and accuracy of experimental sample addition.

[0039] Furthermore, the external terminal also includes a terminal communication module and a terminal image acquisition camera. A communication connection is established between the terminal communication module and the information transmission module of the electric manual sample adding gun. During the use of the electric manual sample adding gun, the terminal image acquisition camera collects photos of each sample adding process node in real time, which are processed by the terminal controller and saved in the terminal memory.

[0040] By adopting the above preferred solution, the terminal image acquisition camera can collect photos of the gun use process in real time as needed, so as to facilitate subsequent tracing and obtain the sample loading status of the sample loading gun and the sample loading target test tube at that time.

The set liquid addition volume is displayed through the display module 507, and the movement stroke of the sample addition control rod remains unchanged as the set liquid addition volume changes;

[0051] The housing body 100 is provided with a piston module, a detection module, a processing module 501, a storage module 502, an information transmission module 503 and a power supply module 504; the detection module is connected to the processing module 501, and the processing module 501 is connected to the piston module, the storage module 502, the information transmission module 503 and the power supply module 504;

[0052] The piston module includes a piston 401 and a motor 402, and the motor 402 drives the piston 401 to move via a transmission member 403;

[0053] The detection module is used to detect the movement of the sample loading control rod 201 and the sample loading adjustment knob 301;

[0054] The processing module 501 receives the movement information of the sample loading control rod 201 and the sample loading adjustment knob 301 detected by the detection module, and after processing, sends out a command signal to control the action of the motor 402, and the motor drives the piston to move up and down after the action;

[0055] The storage module 502 is used to store the sample addition order, the liquid addition volume set by the sample addition adjustment knob, the movement stroke / speed / acceleration of the sample addition control rod, and the actual liquid addition volume information data converted from the motor rotation information;

[0056] The information transmission module 503 is used for wired or wireless communication with an external terminal, so that the external terminal can obtain the information data stored in the storage module 502.

[0057] The beneficial effect of adopting the above technical solution is: a storage module is integrated on the electric manual sample adding gun, and the sample adding information is saved. When the sample adding data needs to be queried, the stored data is directly retrieved, and the originally set liquid addition volume, whether the operation of the sample adding control lever is normal, and the actual liquid addition amount can be traced. It can be determined whether there is any abnormality in the original sample addition, which facilitates the rapid tracing of the root cause of the problem and reduces unnecessary repeated experiments.

[0058] In some other embodiments of the present invention, the processing module 501 is preset with a standard speed range for determining whether the action of the sample loading control rod belongs to normal operation, and the standard speed range is composed of a speed reference value and an allowable deviation value;

[0059] When the actual speed of the sample loading control rod is within the standard speed range, the processing module controls the speed of the motor according to the actual speed of the sample loading control rod, and the speed of the motor is directly proportional to the actual speed of the sample loading control rod;

[0060] When the actual speed of the sample adding control rod exceeds the standard speed range, the processing module corrects and adjusts the motor speed and completes the sample adding amount of the same volume as the set liquid adding volume. The beneficial effect of adopting the above technical solution is that when the sample adding personnel do not use the sample adding gun normally, it can automatically correct the error and complete the sample adding task.

[0061] In other embodiments of the present invention, the speed reference value at each stroke point is a variable value in the full stroke of the sample addition control rod 201, and the standard speed range also changes with the speed reference value. The beneficial effect of adopting the above technical solution is: adapting to the perfect sample addition technique, ensuring the sample addition speed, reducing liquid dripping, and improving the liquid addition accuracy.

[0062] In some other embodiments of the present invention, a learning mode for collecting the speed reference value is also included. In the learning mode, the speed value of the full stroke of the sample adding control rod is collected as the speed reference value. The beneficial effect of adopting the above technical solution is that the mode is convenient for skilled operators to enter better gun-using techniques and convenient for inputting appropriate speed reference values ​​for different use occasions. With the help of an external terminal, a standard gun-using speed curve can be output, which is convenient for teaching gun-using techniques, and beginners can also understand the differences in gun-using techniques more intuitively.

[0063] like Figure 2 , 3As shown, in other embodiments of the present invention, the detection module includes a first sensor 302 for detecting the rotation angle, rotation speed and acceleration of the sample addition adjustment knob 301. The specific configuration form of the first sensor 302 is not limited. It can be in the form of a sliding rheostat or one or more photoelectric sensors. A detection unit matching the optical path of the photoelectric sensor is set on the sample addition adjustment knob to detect the rotation angle of the sample addition adjustment knob, and then calculate the rotation speed and acceleration. For the setting of the liquid addition amount, the change speed of the set value can be matched according to the rotation speed detected by the first sensor, and the magnification of the set value corresponding to the unit rotation angle is set by the rotation acceleration, so that the user can quickly and easily obtain the preset liquid addition volume value. The detection module also includes a second sensor 203 for detecting the displacement, speed and acceleration of the sample addition control rod 201. The second sensor 203 can be a displacement sensor. The detection head of the displacement sensor is installed on the sample addition control rod, and the displacement sensor scale is fixed in the shell body.

[0064] like Figure 4 As shown, in some other embodiments of the present invention, the detection module further includes a direction sensor 505 for detecting the posture of the sample adding gun, and the liquid adding angle information of the sample adding gun is obtained after being processed by the processing module 501 and the liquid adding angle information of the sample adding gun is stored in the storage module. The beneficial effect of adopting the above technical solution is that the gun angle can be easily traced.

[0065] like Figure 4 As shown, in some other embodiments of the present invention, the detection module further includes a pressure sensor 506 installed between the motor transmission member and the piston, and the processing module 501 receives the pressure value information detected by the pressure sensor 506, and saves the pressure value in the storage module after processing. The beneficial effect of adopting the above technical solution is that in different situations such as no load in the piston cylinder of the sample adding gun, liquids of different viscosities, and gun head blockage, after the motor is actuated, the pressure values ​​obtained by the pressure sensor above the piston are different. Through the pressure detected by the pressure sensor, a richer gun use status can be obtained, which is convenient for tracing the gun operation.

[0066] In other embodiments of the present invention, the processing module presets multiple groups of standard speed ranges with different range values, and the processing module selects a group of the standard speed ranges that match the pressure value data detected by the pressure sensor to determine whether the action of the sample addition control lever is a normal operation. The beneficial effect of the above technical solution is that the concentration data of the liquid addition can be understood by means of the pressure detected by the pressure sensor, so as to select the standard speed range that matches the actual liquid addition concentration to guide the gun action, further improving the intelligence of the sample addition gun and improving the final liquid addition accuracy.

[0068] The external terminal includes a terminal controller 601, a terminal memory 602 and a terminal display 603. The terminal memory 602 and the terminal display 603 are both connected to the terminal controller 601. The terminal controller 601 reads the sample loading information data in the electric manual sample loading gun storage module 502 and saves the data in the terminal memory 602. The obtained sample loading information data is used to generate a sample loading information chart on the terminal controller 601 through software, and is displayed to the user through the terminal display 603.

[0069] The beneficial effect of adopting the above technical solution is: the sampling data collected by the sampling gun is processed through the external terminal, the gun usage history and the gun usage process status are more intuitively displayed, and the actual amount of liquid added in the experiment is convenient and fast to trace. It is also more convenient for beginners of the sampling gun to timely understand the difference between the gun usage technique and the standard technique, and can quickly explore the tricks of the gun and improve the accuracy of the experimental sampling.

During the use of the electric manual sample gun, the terminal image acquisition camera 605 collects photos of each sample addition process node in real time, which are processed by the terminal controller 601 and saved in the terminal memory 602. The beneficial effect of adopting the above technical solution is that when adding samples, the terminal image acquisition camera is facing the sample addition operation area, and the terminal image acquisition camera and the external terminal can be integrated or split. The split terminal image acquisition camera is convenient to move to the sample addition operation area alone, and can collect photos of the gun use process in real time as needed, such as collecting the sample addition photos at the beginning and end of the sample addition action of the sample addition control lever, and taking photos and collecting photos immediately when abnormal operation is detected, so as to facilitate the subsequent tracing and obtain the sample addition state of the sample addition gun at that time and the sample addition target test tube.
