Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, and in particular to a battery cell fixing and potting equipment. Background Technology

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes, and is generally not used directly. This differs from a battery, which includes a protection circuit and a casing and can be used directly. A lithium-ion rechargeable battery consists of a battery cell and a protection circuit board. Removing the protection circuit board from the rechargeable battery leaves the battery cell. It is the energy storage component of the rechargeable battery. The quality of the battery cell directly determines the quality of the rechargeable battery.

[0003] In the existing battery cell manufacturing process, electrolyte filling is required. However, the electrolyte filling process cannot reliably and stably fix the battery cell casing, resulting in electrolyte leakage and waste of resources. At the same time, it is not convenient and quick to fill the battery cell. Therefore, we propose a battery cell fixing and filling device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a battery cell fixing and encapsulation device that can stably, reliably, and quickly encapsulate battery cells.

[0005] The technical solution of this utility model is:

[0006] A battery cell fixing and potting device includes a base, a support frame fixedly installed at the top of the base, a battery cell shell disposed at the top of the base and at the middle position of the support frame, clamping plates respectively attached to both sides of the battery cell shell, a movable column fixedly connected to the top and bottom of one side of the clamping plate, the other end of the movable column extending through to the outside of the support frame and fixedly installed with a pull plate, a compression spring installed on the outer surface of the movable column near the clamping plate, and a potting assembly disposed at the top of the support frame.

[0007] In a further technical solution, the filling assembly includes a filling cylinder fixedly installed on a support frame. A fixing plate is fixedly installed inside the filling cylinder. A pressure plate is installed at the top of the filling cylinder. A connecting column is fixedly connected to the lower surface of the pressure plate. A limit spring is installed on the outer surface of the connecting column. The bottom end of the connecting column penetrates into the interior of the filling cylinder and is fixedly connected to a partition. A sealing gasket is installed on the upper surface of the partition. A lower pressure plate is fixedly connected to one end of the connecting column, located at the top of the interior of the filling cylinder. The partition and the sealing gasket are located at the bottom end of the fixing plate.

[0008] In a further technical solution, the fixing plate is a circular ring structure, and the diameter of the hole at the middle end of the fixing plate is larger than the outer diameter of the connecting column and smaller than the outer diameter of the partition.

[0009] In a further technical solution, a drain port is provided at the bottom of the filling cylinder, and a filling pipe is installed at the top of one side of the filling cylinder.

[0010] In a further technical solution, the support frame adopts a U-shaped structure design, with round holes on both sides of the support frame, and the movable column passes through the round holes and can move.

[0011] The beneficial effects of this utility model are:

[0012] The battery cell casing can be clamped and fixed on the base by the clamping plate, pull plate, compression spring and movable column. Then the filling component on the support frame is used to fill it, which improves the stability during filling. The method is also secure and avoids leakage during filling. At the same time, it is simple to operate and easy to use, which can greatly improve filling efficiency. Attached Figure Description

[0018] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0019] like Figures 1-3As shown, a battery cell fixing and potting device includes a base 1, a support frame 2 fixedly installed at the top of the base 1, a battery cell shell 3 disposed at the top of the base 1 and at the middle position of the support frame 2, clamping plates 4 respectively attached to both sides of the battery cell shell 3, a movable column 9 fixedly connected to the top and bottom of one side of the clamping plate 4, the other end of the movable column 9 penetrating to the outside of the support frame 2 and fixedly installed with a pull plate 5, a compression spring 8 installed on the outer surface of the movable column 9 near the clamping plate 4, a filling assembly disposed at the top of the support frame 2, the filling assembly including a filling cylinder 6 fixedly installed on the support frame 2, a fixing plate 11 fixedly installed inside the filling cylinder 6, a pressure plate 7 installed at the top of the filling cylinder 6, and a connecting plate 7 fixedly connected to the lower surface of the pressure plate 7. A limit spring 12 is installed on the outer surface of the column 10. The bottom end of the connecting column 10 penetrates into the interior of the filling cylinder 6 and is fixedly connected to a partition 14. A sealing gasket 15 is installed on the upper surface of the partition 14. A lower pressure plate 13 is fixedly connected to one end of the connecting column 10 and the top of the interior of the filling cylinder 6. The partition 14 and the sealing gasket 15 are located at the bottom of the fixing plate 11. The fixing plate 11 has a circular structure. The diameter of the hole in the middle of the fixing plate 11 is larger than the outer diameter of the connecting column 10 and smaller than the outer diameter of the partition 14. A drain port is opened at the bottom of the filling cylinder 6. A filling pipe 16 is installed at the top of one side of the filling cylinder 6. The support frame 2 adopts a U-shaped structure design. Circular holes are opened on both sides of the support frame 2. The movable column 9 passes through the circular holes and can move.

[0020] The working principle of the above technical solution is as follows:

[0021] When using this device, first place the battery cell casing 3 on the base 1, positioned between the two clamping plates 4. The elastic force of the two compression springs 8 causes the clamping plates 4 to adhere to the outer side of the battery cell casing 3, thus clamping and fixing the battery cell casing 3. Then, add electrolyte to the filling cylinder 6 through the filling tube 16. Pressing the pressure plate 7 moves the connecting column 10, which in turn moves the partition 14, opening the hole on the fixing plate 11. At this time, the electrolyte inside can be filled into the battery cell casing 3 through the drain port at the bottom of the filling cylinder 6. After filling, pull the two pull plates 5 to release the clamping of the battery cell casing 3. Replace the other battery cell casing 3 and fill it using the same steps.

[0022] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
