[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] See also Figure 1 and Figure 2 The utility model provides a liquid filling device, including an air charging device, a liquid filling device, a first driving member 3, a second driving member 4, a capping device and a controller (not shown in the figure).

[0035] See also Figure 1 and Figure 2The gas filling device includes a gas filling gun head 1, and the gas filling gun head at least partially extends into the container body of the liquid container (not shown in the figure) and fills the container body with nitrogen. It should be noted that before filling the liquid into the container body through the liquid filling device, nitrogen needs to be introduced into the container body to expel air so that the container body is filled with nitrogen. During the process of filling the liquid, nitrogen also needs to be introduced into the container body all the time to continuously protect the liquid from contacting with air.

[0036] The liquid container includes a container body and a cover body, and the cover body is detachably mounted on the container body to seal the container body. The material and size of the liquid container can be selected according to the properties of the liquid, and no further restrictions are made here.

[0037] In this way, by extending the inflation gun head 1 into the container body, all the air in the container body, including the bottom of the container body, is discharged from the container body to avoid contact between the liquid and the air. Dust and impurities in the air may affect the yield rate of the finished product of the filling liquid, and some liquids are easily oxidized in the air, which will also affect the yield rate of the finished product of the filling liquid.

[0038] See also Figure 2 The filling device includes a filling gun head 2, which extends into the container body and fills the container body with liquid. The first driving member 3 is used to drive the inflation gun head 1 and the filling gun head 2 to move along the first direction X; the second driving member 4 is used to drive the inflation gun head 1 and the filling gun head 2 to move along the second direction Y. The controller is in communication connection with the first driving member 3 and the second driving member 4; the first direction X and the second direction Y are perpendicular to each other.

[0039] In this way, by setting the filling gun head 2, the filling gun head 2 is extended into the container body to fill the container body with liquid, and the movement and filling action of the filling gun head can be controlled by the controller, which is beneficial to improving the filling efficiency and saving manpower.

[0040] In some embodiments, the first driving member 3 is a servo drive motor.

[0044] In this way, by setting up a capping device, manpower can be saved and the capping efficiency can be improved. For liquids that are easily volatile, the evaporation time of the liquid can be shortened, thereby reducing liquid evaporation and preventing liquid evaporation from affecting the concentration of the filling liquid, thereby affecting the yield of the finished product.

[0045] In some embodiments, the rotary drive member 7 is a servo drive motor and can realize forward and reverse rotation.

[0046] In some embodiments, the grab driving member 6 is a cylinder.

[0047] It is understandable that the rotation drive member 92 and the grabbing drive member 6 can also be selected according to actual use requirements and are not limited to the examples in this embodiment.

[0049] Optionally, the transmission member is a transmission rod.

[0050] In this way, the controller controls the grasping drive 6 to open or tighten the multiple jaws 51 at the same time, so that the multiple jaws 51 release or grasp the cover body. The operation is simple and efficient, and the automation level of the liquid filling equipment can also be improved.

[0051] See also Figure 3 In some embodiments, the gripper assembly 5 further includes a transmission structure 52, which is rotatably connected to the rotating drive member 7. The rotating drive member 7 drives the transmission structure 52 to rotate, so that the transmission structure 52 drives the plurality of jaws 51 to rotate, thereby tightening or reversely loosening the cover body.

[0052] In this way, the controller controls the rotating driving member 7 to rotate forward or reverse to drive the transmission structure 52 to rotate forward or reverse, and the transmission structure 52 drives the multiple clamping claws 51 to rotate forward or reverse, thereby tightening or reversely loosening the cover.

[0053] It should be noted that, before the controller controls the rotating driving member 7 to open, it needs to first control the grabbing driving member 6 to grab the cover body.

[0054] See also Figure 3 Further, in some embodiments, the transmission structure 52 includes a first gear 521, a second gear 522 and a transmission cylinder 523 which are sequentially connected. The output end of the rotary drive member 7 is fixedly connected to the gear shaft of the first gear 521, the first gear 521 is fixedly connected to the gear shaft, and the first gear 521 is meshed with the second gear 522.

The controller controls the second driving member 4 to drive the filling gun head 2 to move along the second direction Y away from the container body according to the liquid level height data.

[0056] In this way, by setting up the liquid level detection unit, during the process of filling the liquid, the controller can control the second driving member 4 to drive the filling gun head 2 to move along the second direction Y away from the container body according to the liquid level height data in the container body, thereby avoiding the filling gun head 2 extending into the liquid and causing bubbles to be generated, which is beneficial to improving the stable accuracy of the filling liquid and can also avoid affecting the finished product yield of the filling liquid.

[0057] In some embodiments, the liquid level detection unit is an electronic scale, the container body is placed on the electronic scale, and the controller can convert the weight data obtained by the electronic scale into liquid level height data.

[0058] In some embodiments, the liquid level detection unit is a liquid level detector.

[0059] It is understandable that the liquid level detection unit can directly detect the liquid level height data in the container body, or can detect other data and then convert it into liquid level height data through the controller.

In order to prevent the residual liquid from dripping onto the ground or the filling platform, a residual liquid collection device 9 is provided to collect the residual liquid through the collection container 91 to avoid contamination.

[0062] In some embodiments, the rotary drive member 92 is a servo drive motor. It is understandable that the rotary drive member 92 can also select other drive devices according to actual use needs, and is not limited to the servo drive motor in this embodiment.

[0063] In some embodiments, the inflation device further includes a nitrogen tank (not shown in the figure), in which nitrogen is stored, and one end of the inflation gun head 1 is connected to the nitrogen tank.
