[0056] Please see Figure 1 This application proposes a battery production equipment 1000 for producing batteries 700. The battery production equipment 1000 includes a material tray 200, a transfer device 300, a blocking device 400, and a liquid injection device 100.

[0057] The material tray 200 is used to carry multiple batteries 700. The transfer device 300 is used to transport the material tray 200 to the workstation. The blocking device 400 is used to limit the material tray 200 at the workstation or release the material tray 200 from the workstation. The liquid injection device 100 is located at the workstation.

[0058] Please see Figure 2 In the production process of battery 700, to improve production efficiency, a material pallet 200 is used to carry multiple batteries 700 at once, thus enabling the processing of multiple batteries 700 simultaneously. The transfer device 300 can be a conveyor belt, conveyor rollers, cylinders, hydraulic cylinders, forklifts, robotic arms, etc., and no limitation is made to the transfer device 300 here. Taking conveyor rollers as an example, when the conveyor rollers transport the material pallet 200 to the workstation, the blocking device 400 limits the material pallet 200 from continuing to move and stops it at the workstation.

[0059] Optionally, the battery production equipment 1000 also includes a lifting device 700. The lifting device 700 is located below the workstation and is used to lift the material tray 200 from the workstation. When the blocking device 400 limits the material tray 200 at the workstation, the lifting device 700 lifts the material tray 200 upwards so that the liquid injection device 100 can inject liquid into the batteries 700 on the material tray 200. After the liquid injection device 100 completes the liquid injection, the lifting device 500 descends, the material tray 200 falls back onto the workstation, and is then transported by the transfer device 300 to the processing station for the next processing step.

[0060] Please see Figure 3This application discloses a liquid injection device 100, including a liquid injection mechanism 10 and a transfer mechanism 20. The liquid injection mechanism 10 includes a liquid injection component 11 and a liquid receiving component 12. The liquid injection component 11 is used to communicate with the liquid injection chamber of the battery 700 to form a negative pressure environment and inject electrolyte into the liquid injection chamber of the battery 700. The liquid receiving component 12 is used to collect any residual electrolyte in the liquid injection component 11.

[0061] The output end of the transfer mechanism 20 is connected to the injection assembly 11 and drives the injection assembly 11 to move. The transfer mechanism 20 can be a transmission structure such as a cylinder, hydraulic cylinder, robotic arm, or motor.

[0062] In this embodiment, after the lifting device 500 lifts the material tray 200 at the workstation, the transfer mechanism 20 drives the electrolyte injection assembly 11 to approach the battery 700 and inject electrolyte into the electrolyte injection chamber of the battery 700. After the electrolyte injection assembly 11 completes the injection, the lifting device 500 descends, the material tray 200 descends to the workstation, and the electrolyte receiving assembly 12 collects the residual electrolyte in the electrolyte injection assembly 11, which can improve the technical problem of electrolyte leakage and reduce safety risks.

[0063] Optionally, the transfer mechanism 20 is located above the workstation, with its output end facing the workstation, and is used to drive the liquid injection assembly 11 to move closer to or away from the workstation in a vertical direction.

[0064] The liquid receiving assembly 12 includes a liquid receiving element 12a and a first driving element 12b. The liquid receiving element 12a is used to collect residual electrolyte in the liquid injection assembly 11. The first driving element 12b is drivenly connected to the liquid receiving element 12a and is used to drive the liquid receiving element 12a closer to or further away from the liquid injection assembly 11.

[0065] The first driving component 12b is located between the transfer mechanism 20 and the lifting device 500, and is used to drive the liquid receiving component 12a to move closer to or away from the work position in the horizontal direction.

[0066] In this embodiment, after the lifting device 500 lifts the material tray 200 at the workstation, the transfer mechanism 20 drives the liquid injection assembly 11 to move vertically downwards towards the lifted material tray 200 and communicate with the liquid injection chamber of the battery 700 on the material tray 200 to inject liquid into the battery 700. After the liquid injection is completed, the lifting device 500 lowers the material tray 200. The first driving member 12b located between the lifting device 500 and the transfer mechanism 20 drives the liquid receiving member 12a to move horizontally towards the workstation, so that the liquid receiving member 12a moves below the liquid injection assembly 11. After the liquid injection assembly 11 releases the residual electrolyte into the liquid receiving member 12a, the first driving member 12b moves horizontally away from the workstation, completing the collection of the residual electrolyte in the liquid injection assembly 11.

[0067] This application discloses a liquid injection mechanism 10, including a liquid injection assembly 11 and a liquid receiving assembly 12. The liquid injection assembly 11 is used to communicate with the liquid injection chamber of the battery 700 to form a negative pressure environment and inject electrolyte into the liquid injection chamber of the battery 700. The liquid receiving assembly 12 is used to collect any residual electrolyte in the liquid injection assembly 11.

[0068] The liquid receiving assembly 12 includes a liquid receiving element 12a and a first driving element 12b. The liquid receiving element 12a is used to collect residual electrolyte in the liquid injection assembly 11. The first driving element 12b is drivenly connected to the liquid receiving element 12a and is used to drive the liquid receiving element 12a closer to or further away from the liquid injection assembly 11.

[0069] In this embodiment, after the electrolyte injection assembly 11 completes the electrolyte injection, the first driving member 12b drives the receiving member 12a to approach the electrolyte injection assembly 11, so that the residual electrolyte in the electrolyte injection assembly 11 is discharged into the receiving member 12a. After the receiving member 12a completes the collection of the residual electrolyte in the electrolyte injection assembly 11, the first driving member 12b drives the receiving member 12a away from the electrolyte injection assembly 11, so that the electrolyte injection assembly 11 can inject electrolyte into the electrolyte injection chamber of the next batch of batteries 700. This can reduce the leakage of residual electrolyte after the electrolyte injection assembly 11 injects electrolyte, thereby improving the technical problem of electrolyte leakage and reducing safety risks.

[0070] The first driving component 12b can be a cylinder, hydraulic cylinder, electrode, robotic arm, or other structure, and no limitation is made to the first driving component 12b here. In this embodiment, the first driving component 12b can be a pen-shaped cylinder.

[0071] Optionally, the injection assembly 11 includes an air extraction head 11b and an injection head 11a.

[0072] The suction head 11b is used to connect to the liquid filling chamber of the battery 700 and form a negative pressure environment with the liquid filling chamber of the battery 700.

[0073] The electrolyte injection head 11a is used to connect to the electrolyte injection chamber of the battery 700 and inject electrolyte into the electrolyte injection chamber of the battery 700.

[0074] In this embodiment, the surface of the battery 700 includes a suction port and a liquid injection port communicating with its liquid injection chamber. Before liquid injection, the transfer mechanism 20 drives the liquid injection assembly 11 close to the material tray 200, and connects the suction head 11b to the suction port of the battery 700, and the liquid injection head 11a to the suction port of the battery 700. At this time, the suction head 11b, the liquid injection head 11a, and the liquid injection chamber of the battery 700 form a sealed space. The suction head first draws negative pressure into the liquid injection chamber of the battery 700, and then the liquid injection head 11a injects liquid into the liquid injection chamber of the battery 700. After completing the liquid injection of one row of batteries 700 on the material tray 200, the transfer mechanism 20 drives the liquid injection assembly 11 to rise.

[0075] Optionally, the liquid injection device 100 also includes a translation mechanism 600. The translation mechanism 600 is driven to the liquid injection assembly 11. The translation mechanism 600 is used to drive the liquid injection assembly 11 to move horizontally above another row of batteries 700 on the material tray 200. The transfer mechanism 20 drives the liquid injection assembly 11 to descend and repeats the above-described liquid injection process until all batteries 700 on the tray have been injected.

[0076] In this embodiment, since the injection head 11a forms a sealed space with the injection chamber of the battery 700, the electrolyte will not leak into the environment when the injection head 11a injects electrolyte into the injection chamber, reducing safety risks. Furthermore, due to the installation of the suction head 11b, a pressure difference can be created inside and outside the battery 700, thereby achieving precise electrolyte injection and ensuring the consistency of electrolyte volume in each battery 700, thus improving the performance and lifespan of the battery 700. This embodiment has a high degree of automation, improves production efficiency, reduces manual operation, and lowers safety risks.

[0077] After all the batteries 700 on the tray have been filled with electrolyte, the lifting device 500 lowers the material tray 200, and the transfer mechanism 20 raises the electrolyte filling assembly 11. The first driving member 12b drives the receiving member 12a to move below the filling head 11a, releasing the residual electrolyte in the filling head 11a into the receiving member 12a. The receiving member 12a collects the residual electrolyte, improving the technical problem of electrolyte leakage and reducing safety risks.

[0078] Optionally, the liquid injection mechanism 10 further includes a vacuum assembly and a liquid storage assembly. The vacuum assembly is connected to the vacuum head 11b and is used to extract gas from the liquid injection chamber of the battery 700 to create a negative pressure environment. The liquid storage assembly is connected to the liquid injection head 11a and is used to inject electrolyte into the liquid injection chamber of the battery 700.

[0079] In this embodiment, the evacuation assembly can be a vacuum pump, an air pump, or other similar structure, and is not limited thereto. The liquid storage assembly is used to store the electrolyte.

[0080] Optionally, the top of the liquid receiving component 12a is provided with a liquid receiving tank for collecting residual electrolyte from the liquid injection assembly 11.

[0081] In this embodiment, the design of the receiving tank can effectively collect the electrolyte, prevent residual electrolyte from dripping from the injection head 11a and polluting the environment, improve the problem of electrolyte leakage, and reduce safety risks.

[0082] Optionally, the liquid receiving component 12a is located below the liquid injection assembly 11. The first driving component 12b is used to drive the liquid receiving component 12a to move in the horizontal direction.

[0083] In this embodiment, since the first driving member 12b can drive the liquid receiving member 12a to the bottom of the liquid injection assembly 11 in the horizontal direction, after the first driving member 12b approaches the liquid injection assembly 11, the liquid injection head 11a directly releases the residual electrolyte inside, and the liquid receiving tank can complete the collection of the residual electrolyte, thereby improving the collection efficiency.

[0084] Optionally, the bottom 122 of the liquid receiving component 12a has a drain port 121, which is connected to the liquid receiving tank. The drain port 121 is used to connect to the drain pipe and discharge the electrolyte collected in the liquid receiving tank.

[0085] In this embodiment, when a large amount of electrolyte is collected in the receiving tank, the electrolyte in the receiving tank needs to be drained to avoid the electrolyte overflowing and polluting the environment, thereby improving the problem of electrolyte leakage and reducing safety risks.

[0086] Optionally, the liquid receiving tank extends along the length direction D1 of the liquid receiving member 12a. The drain port 121 is correspondingly located at one end of the liquid receiving tank along the length direction D1. The bottom wall of the liquid receiving tank slopes upward from the drain port 121 towards the other end of the liquid receiving tank along the length direction D1.

[0087] If the drain outlet 121 is only located at the bottom 122 of the receiving tank, the electrolyte adhering to the bottom wall of the receiving tank will not be completely drained when the receiving tank discharges electrolyte, and some of the collected electrolyte will still adhere to the bottom wall of the receiving tank.

[0088] Please see Figure 4 In this embodiment, to ensure the electrolyte in the receiving tank is completely drained, the bottom wall of the receiving tank is designed with an inclined shape. In this inclined shape, the electrolyte adhering to the bottom wall will flow along the bottom wall under the influence of gravity and be discharged from the drain port 121. This embodiment can completely drain the electrolyte in the receiving tank, improving the electrolyte recycling rate, and at the same time reducing the problem of electrolyte contamination by environmental dust due to prolonged retention in the receiving tank.

[0089] Optionally, the liquid receiving member 12a includes a bottom 122, two first side portions 123, and two second side portions 124. The bottom 122 extends along the length direction D1 of the liquid receiving member 12a and is inclined. A drain port 121 is provided at the downwardly inclined end of the bottom 122. The two first side portions 123 are arranged opposite to each other. The first side portions 123 extend along the length direction D1 of the liquid receiving member 12a. The two second side portions 124 are arranged opposite to each other. The second side portions 124 extend along the width direction of the liquid receiving member 12a. The two first side portions 123 and the two second side portions 124 surround the edge of the bottom 122 and form a liquid receiving groove. A first driving member 12b is connected to the first side portions 123 and is used to drive the liquid receiving member 12a to move along the width direction of the liquid receiving member 12a.

[0090] In this embodiment, the bottom 122 of the liquid receiving member 12a is inclined, and a drain port 121 is provided at the downward inclined end of the bottom 122. During the draining process of the liquid receiving member 12a, the electrolyte adhering to the bottom 122 is subjected to gravity and flows towards the drain port 121, thereby being discharged from the liquid receiving tank. Two first side portions 123 and two second side portions 124 surround the edge of the bottom 122 and form a liquid receiving tank.

[0091] To improve the stability of the connection between the first connector and the liquid receiving component 12a, the first connector is connected to the first side portion 123 extending along the length direction D1. This increases the contact area between the first connector and the liquid receiving component 12a, resulting in a more stable connection. This prevents the liquid receiving component 12a from tipping over due to unstable connection, which could cause electrolyte overflow or leakage from the receiving tank and lead to environmental pollution. This embodiment can improve the technical problem of electrolyte leakage and reduce safety risks.

[0092] Please see Figure 5 Optionally, the liquid receiving assembly 12 also includes a cover plate 125. The cover plate 125 is movably disposed on top of the liquid receiving member 12a for closing or exposing the liquid receiving tank.

[0093] In this embodiment, since the first driving member 12b drives the liquid receiving member 12a to move closer to or away from the workstation in the horizontal direction, a movable cover plate 125 can be provided on the top of the liquid receiving member 12a. Before the liquid injection assembly 11 releases the residual electrolyte, the cover plate 125 opens and exposes the liquid receiving tank of the liquid receiving member 12a, and the liquid injection assembly 11 releases the residual electrolyte into the liquid receiving tank. After the liquid injection assembly 11 has released the electrolyte, the cover plate 125 closes and seals the liquid receiving tank of the liquid receiving member 12a. The design of the cover plate 125 can reduce the risk of electrolyte leakage during the movement of the liquid receiving assembly 12.

[0094] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
