The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0029] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0031] See Figure 1 One embodiment of this application provides a liquid metering device, including: an input module 1, a controller 2, an electronic pump 3, a liquid storage tank 4, a bracket 5, a liquid transfer tank 6, a dispensing gun 7, and multiple liquid level sensors 8;

[0032] The liquid transfer tank 6 is mounted on the support 5;

[0033] The electronic pump 3 is connected to the liquid storage tank 4 and the liquid transfer tank 6 via pipelines, and is also connected to the controller 2;

[0034] Multiple liquid level sensors 8 are disposed inside the liquid transfer tank 6 and are respectively connected to the controller 2. The multiple liquid level sensors 8 are arranged inside the liquid transfer tank 6 according to multiple different filling heights.

[0035] The filling gun 7 is connected to the liquid transfer tank 6 through a filling pipeline, and a filling switch 701 is provided on the filling gun 7;

[0036] The input module 1 is connected to the controller 2 and is used to input the refueling type information to the controller 2;

[0037] The controller 2 receives the filling type information, connects to the target liquid level sensor 8 associated with the filling height, sends a start signal to the electronic pump 3, and sends a stop signal to the electronic pump 3 after receiving the liquid level signal sent by the target liquid level sensor 8.

[0038] The liquid metering device provided in this embodiment includes a liquid transfer tank 6, which is connected to a liquid storage tank 4 via a sub-pump to pump liquid from the liquid storage tank 4 into the liquid transfer tank 6. It is also connected to a dispensing gun 7 via a dispensing pipeline. The dispensing gun 7 is used to insert into the dispensing port of the liquid tank to be dispensed, so as to inject liquid from the liquid transfer tank 6 into the liquid tank to be dispensed. Thus, when dispensing liquid, liquid is first pumped from the liquid storage tank into the liquid transfer tank 6, and then the liquid in the liquid transfer tank 6 is dispensed into the liquid tank to be dispensed through the dispensing gun 7, thereby realizing basic liquid dispensing.

[0039] Preferably, in this embodiment, the liquid transfer tank 6 is provided with multiple liquid level sensors 8 arranged according to different filling heights. Each filling height corresponds to a filling amount, so that the liquid level sensor 8 can accurately determine the amount pumped into the liquid transfer tank 6, thereby facilitating accurate quantitative filling for different models.

[0040] Furthermore, the liquid metering dispensing device also includes a controller 2 and an input module 1. The controller 2 is connected to the input module 1, the liquid level sensor 8, and the electronic pump 3. After receiving the dispensing type information input from the input module 1, the controller 2 can determine the required dispensing volume based on the dispensing type information, and then connect the target liquid level sensor 8 corresponding to the dispensing height, causing the target liquid level sensor 8 to start or causing the controller 2 to only receive or process the signal transmitted by the target liquid level sensor 8. At the same time, the controller 2 also sends a start signal to the electronic pump 3, causing the electronic pump 3 to start according to the start signal. A dynamic signal is activated to pump liquid into the liquid transfer tank 6. The target liquid level sensor 8 monitors whether the liquid level has reached the corresponding height. When the corresponding height is reached, a liquid level signal is sent to the controller 2. After receiving the liquid level signal, the controller 2 determines that the pumped liquid has reached the required amount, and therefore sends a stop signal to the electronic pump 3. The electronic pump 3 stops according to the stop signal, ensuring that the pumped amount is the required amount. Furthermore, the liquid can be added to the liquid tank by opening the filling switch 701 on the filling gun 7, thereby achieving precise quantitative filling.

[0041] Specifically, the liquid transfer tank 6 is mounted on the support 5. In addition to fixing the liquid transfer tank 6, the support 5 also raises the liquid transfer tank 6 to a certain height, which makes it easier to use potential energy for slow liquid filling. This facilitates the timely discharge of the liquid in the tank to be filled, which helps to improve efficiency and avoid spillage.

[0042] Specifically, the filling pipeline and the pipeline connecting the electronic pump 3 are both located at the bottom of the liquid transfer tank 6, so that no large splashes or waves are generated when liquid is pumped into the liquid transfer tank 6, ensuring the stability of the liquid surface and thus ensuring the accuracy of the detection by the liquid level sensor 8.

[0043] In summary, the liquid metering device provided in this embodiment can achieve metered dispensing and can dispense the corresponding metered amount of liquid into the liquid tank according to different dispensing type information, solving the problem of inability to dispense metered liquid in the prior art. By setting the dispensing gun 7 to be inserted into the dispensing port of the liquid tank and using potential energy for slow dispensing, the risk of spillage is avoided and the intensity of manual labor is reduced.

[0044] In one specific embodiment, the filling switch 701 can control the flow rate of the filling liquid by changing the opening area, thereby further avoiding the risk of spillage.

[0045] In one specific embodiment, the controller 2 is preferably a programmable logic controller (PLC).

[0046] Optionally, in the liquid metering dispensing device described above, the dispensing switch 701 is connected to the controller 2;

[0047] After receiving the liquid level signal sent by the target liquid level sensor 8, the controller 2 will also send a filling signal to the filling switch 701. The filling signal is used to switch the filling switch 701 from the closed state to the connected state.

[0048] In this embodiment, the filling switch 701 is preferably an electronic switch, which is connected to the controller 2. When the controller 2 receives the liquid level signal sent by the target liquid level sensor 8, it determines that the liquid in the liquid transfer tank 6 has reached the required amount. At this time, while turning off the electronic pump 3, it also sends a filling signal to the filling switch 701, so that the filling switch 701 switches from the closed state to the connected state, so as to start the liquid filling.

[0049] In another embodiment, the filling signal may also carry an opening area control command corresponding to the filling height. The filling switch 701 controls the opening area according to the opening area control command in the filling signal, so that different filling amounts correspond to the same initial flow rate, further preventing spillage.

[0050] Preferably, the liquid metering dispensing device as described above further includes:

[0051] A filling cap 702 is fitted onto the filling gun 7. The filling cap 702 is configured to correspond to the filling port of the liquid tank to be filled. The filling cap 702 is also provided with at least one vent 703.

[0052] In this embodiment, the dispensing gun 7 is also fitted with a dispensing cap 702 corresponding to the dispensing port. This cap 702 reduces the risk of foreign objects entering the dispensing port and liquid leakage, while ensuring a secure connection between the dispensing gun 7 and the dispensing port, thus reducing manual labor. Furthermore, the dispensing cap 702 is also provided with at least one vent 703 to facilitate the discharge of gas from the liquid tank to be dispensed.

[0053] Optionally, the liquid metering dispensing device described above further includes:

[0054] A vent tube is inserted into the vent 703.

[0055] In this embodiment, to further reduce the risk of foreign objects entering the filling port and liquid leaking from the filling port, a vent pipe will also be inserted into the vent 703.

[0056] Preferably, in the liquid metering device described above, at least a portion of the liquid transfer tank 6 is a transparent structure, and the first height range of the transparent structure is greater than the second height range where the plurality of liquid level sensors 8 are located.

[0057] In this embodiment, at least a portion of the liquid transfer tank 6 is a transparent structure. This transparent structure allows workers to easily observe whether the liquid level in the liquid transfer tank 6 has reached the corresponding position of the liquid level sensor 8, thereby facilitating timely detection of problems and timely adjustments.

[0058] Furthermore, in the liquid metering device described above, the transparent structure is provided with height or volume scale lines.

[0059] In this embodiment, height or volume scale lines can also be provided at the transparent structure so that workers can observe the liquid level in real time, thereby facilitating timely detection of problems and timely adjustments.

[0060] Optionally, in the liquid metering dispensing device described above, the input module 1 is one of a control panel, a model detection module, and a data interface, wherein the data interface is connected to the manufacturing execution system and is used to receive the dispensing type information obtained by the manufacturing execution system.

[0061] In one embodiment, input module 1 can be one of a control panel, a model detection module, or a data interface. When input module 1 is a control panel, workers can manually input or select the model to be added. When input module 1 is a model detection module, the model to be added can be detected to determine the model to be added. When input module 1 is a data interface, it can be connected to the manufacturing execution system to receive the model information obtained by the manufacturing execution system.

[0062] Optionally, the liquid metering dispensing device described above further includes:

[0063] Multiple casters are located at the bottom of the bracket 5.

[0064] In this embodiment, multiple casters are also provided at the bottom of the bracket 5 to facilitate the movement of the liquid dispensing device. Furthermore, a braking structure is also provided at the bottom of the bracket 5 to restrict the movement of the casters. Preferably, the braking structure is provided on the casters.

[0065] Furthermore, reference numerals and / or letters may be repeated in different examples within this application. Such repetition is for the purpose of simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed.

[0066] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion.

[0067] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
