[0006] Bracket;

[0007] A driving module, wherein the driving module is installed on the bracket;

[0008] The pressing piece includes a fixing part and a pressing part, the fixing part is mounted on the driving end of the driving module, and the pressing part is mounted on the fixing part and has a mesh structure;

[0009] The driving module is used to control the movement of the fixing portion so that the pressing portion can at least partially extend into the liquid injection hole of the battery.

[0010] Furthermore, the pressing part is funnel-shaped, and the fixing part is arranged on the large-diameter end of the pressing part.

[0011] Furthermore, the fixing portion is in a truncated cone shape, and the small bottom of the fixing portion is connected to the large-diameter end of the pressing portion.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] Embodiment 1:

[0029] This embodiment provides a tool for pressing and preventing liquid accumulation in a liquid injection port, comprising:

[0030] Bracket;

[0031] A driving module, wherein the driving module is installed on the bracket;

[0032] The pressing part 1 comprises a fixing part 2 and a pressing part 3, wherein the fixing part 2 is mounted on the driving end of the driving module, and the pressing part 3 is mounted on the fixing part 2 and has a mesh structure;

[0033] The driving module is used to control the movement of the fixing portion 2 so that the pressing portion 3 can at least partially extend into the liquid injection hole of the battery.

[0034] In this technical solution, the battery after the injection is transported to the next process through a conveying device, which can be a conveyor belt. The tooling for pressing to prevent the liquid accumulation at the injection port is installed above the conveying device, and the pressing part 1 is located above the battery being transported. When the battery is transported under the pressing part 1, the conveying device stops working, the battery stops under the pressing part 1 and the injection hole of the battery faces the pressing part 1, and then the driving module controls the movement of the pressing part 1, and the pressing part 3 of the pressing part 1 partially extends into the battery injection hole and abuts against the inner wall of the injection hole. If electrolyte is accumulated in the injection hole of the battery, the electrolyte will flow into the pressing part 3 from the mesh of the pressing part 3 due to the squeezing of the pressing part 3 and the injection hole, and then flow out from the mesh of the pressing part 3 below the injection hole and fall into the battery, thereby achieving the function of allowing the electrolyte on the injection hole to flow back into the battery, which can prevent the electrolyte from contaminating the battery injection hole and reduce the waste of electrolyte, effectively improving the economic benefits and having high practicality.

[0035] In addition, the driving module controls the pressing part 3 of the pressing piece 1 to partially extend into the battery filling hole, which will also cause a certain degree of depression in the battery filling hole, so that the electrolyte around the filling hole can gather at the filling hole, and then flow back to the inside of the battery through the mesh of the pressing part 3, which helps the electrolyte attached to the outside of the battery filling hole to flow back into the battery.

[0036] Embodiment 2:

[0037] This embodiment provides a tooling for pressing to prevent liquid accumulation at a liquid injection port. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features.

[0038] Furthermore, the pressing part 3 is funnel-shaped, and the fixing part 2 is arranged on the large-diameter end of the pressing part 3 .

[0039] In this technical solution, the overall shape of the press-fit part 3 is designed to be funnel-shaped, and the large-diameter end of the press-fit part 3 is used to connect with the fixed part 2. The fixed part 2 is driven to move by the driving module to drive the small-diameter section of the press-fit part 3 to extend into the battery injection hole, and the middle section of the press-fit part 3 is in contact with the inner wall of the injection hole, thereby squeezing the electrolyte in the injection hole, so that the electrolyte flows from the mesh flow channel press-fit part 3 on the middle section, and then slides down along the inner wall of the press-fit part 3 by gravity, and finally flows into the battery through the mesh of the small-diameter section. Through this structural design, the electrolyte at the injection hole can be more easily returned to the battery, improving practicality.

[0040] Embodiment 3:

[0041] This embodiment provides a tooling for pressing to prevent liquid accumulation at a liquid injection port. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features.

[0042] Furthermore, the fixing part 2 is in a truncated cone shape, and the small bottom of the fixing part 2 is connected to the large-diameter end of the pressing part 3 .

[0043] In the present technical solution, the fixing part 2 can be truncated cone or cylindrical, or other shapes, as long as it can be connected and fixed with the pressing part 3. Further, the fixing part 2 is a hollow structure. The fixing part 2 can be designed as a solid structure or a hollow structure. Under the condition of ensuring that the structural strength of the fixing part 2 is sufficient, the fixing part 2 is designed as a hollow structure, which can reduce the input of manufacturing materials, reduce production costs, and effectively improve economic benefits.

[0044] Embodiment 4:

[0045] This embodiment provides a tooling for pressing to prevent liquid accumulation at a liquid injection port. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features.

[0046] Furthermore, the fixing portion 2 and the pressing portion 3 are integrally connected.

[0047] In this technical solution, by designing the fixing part 2 and the pressing part 3 as an integrated structure, the connection strength and stability between the fixing part 2 and the pressing part 3 are enhanced, thereby improving the overall structural strength and stability of the pressing part 1, so that the pressing part 1 can transmit and disperse the force more evenly when subjected to force, reduce the risk of breakage and deformation, and increase the service life. In addition, the integrated design also reduces the assembly steps, simplifies the production process, improves production efficiency, and has higher economic benefits.

[0048] Embodiment 5:

[0052] A driving member 5 , a driving end of which is connected to the linkage member 4 , is used to control the movement of the linkage member 4 .

[0053] Furthermore, the linkage member 4 is a push rod.

[0054] Furthermore, the driving member 5 is any one of an electric cylinder and a pneumatic cylinder.

[0055] In the present technical solution, the driving member 5 is installed on the bracket. The driving member 5 can be an electric cylinder or a pneumatic cylinder. The linkage member 4 is a push rod. One end of the push rod is connected to the piston of the electric cylinder or the pneumatic cylinder, and the other end is connected to the fixed part 2 of the pressing part 1. The push rod is driven up and down by the electric cylinder or the pneumatic cylinder to drive the pressing part 1 to move up and down, thereby realizing the plug-in fit between the pressing part 3 of the pressing part 1 and the battery filling hole.

[0056] It is worth mentioning that the driving member 5 can also be other mechanisms that can control the up and down movement of the push rod. The connection between the push rod and the fixed part 2 can be an integral connection or a detachable connection. By setting an external thread at the end of the push rod and setting a threaded hole at the top of the fixed part 2, the push rod and the fixed part 2 are threadedly connected together.
