Description

Technical Field

[0001] This utility model relates to the field of battery cell technology, and in particular to a filling device for battery cell thermal conductive gel. 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, a gel needs to be filled between the battery cell and the battery casing to fix it and improve heat dissipation. However, the gel is usually made of a mixture of multiple materials, and its quality will be reduced if it is not mixed after being left for a long time. Therefore, we propose a filling device for thermal conductive gel in battery cells. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a filling device for thermally conductive gel in battery cells, which has a good stirring function and can stir the gel before filling.

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

[0006] A filling device for thermal conductive gel in battery cells includes a base, a support frame fixedly connected to the top of the base, a mixing tank fixedly connected to the top of the support frame, a drive motor fixedly mounted on the top of the mixing tank via a motor bracket, an output shaft at the bottom of the drive motor, a mixing shaft mounted on the output shaft via a coupling, a mixing rod fixedly mounted on both the top and bottom of the outer side of the mixing shaft, a discharge pipe fixedly connected to the bottom of the mixing tank, and a feeding mechanism located at the discharge pipe.

[0007] In a further technical solution, the feeding mechanism includes a connecting column, a sealing plate fixedly connected to the top of the connecting column, a base plate fixedly connected to the bottom of the connecting column, a fixing plate fixedly installed on the outer surface of the discharge pipe, a movable plate movably installed on the outer surface of the discharge pipe and located at the top of the fixing plate, limit posts fixedly connected to both sides of the lower surface of the movable plate, the bottom end of the limit post penetrating the fixing plate and fixedly connected to the base plate, and a return spring installed on the outer surface of the limit post.

[0008] In a further technical solution, a sealing gasket is installed on the lower surface of the sealing plate, and the sealing plate and the sealing gasket are located at the bottom of the inner wall of the mixing tank.

[0009] In a further technical solution, the discharge pipe has an internal hollow structure, and multiple through holes are opened on the outer side of the top of the connecting column.

[0010] In a further technical solution, a discharge port is provided on the lower surface of the base plate, and the discharge port is connected to the hollow structural space inside the connecting column and the through hole.

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

[0012] The mixing tank, drive motor, mixing shaft, and mixing rod installed on the top of the support frame can stir the gel stored inside the mixing tank, preventing the gel's quality from being affected by prolonged storage. At the same time, the designed feeding mechanism can cleverly feed the gel, eliminating the need for conventional plugs for sealing and preventing gel from dripping onto people's skin when the plug is opened. It is easy to use, ingeniously structured, and highly practical. Attached Figure Description

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

[0019] As shown in Figure 1- Figure 3As shown, a filling device for thermal conductive gel in battery cells includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a mixing tank 3 fixedly connected to the top of the support frame 2, a drive motor 4 fixedly mounted on the top of the mixing tank 3 via a motor bracket 8, an output shaft 9 at the bottom of the drive motor 4, a mixing shaft 11 mounted on the output shaft 9 via a coupling 10, a mixing rod 12 fixedly mounted on both the top and bottom of the outer side of the mixing shaft 11, a discharge pipe 5 fixedly connected to the bottom of the mixing tank 3, a feeding mechanism located at the discharge pipe 5, the feeding mechanism including a connecting column 15, a sealing plate 13 fixedly connected to the top of the connecting column 15, a base plate 6 fixedly connected to the bottom of the connecting column 15, a fixing plate 16 fixedly mounted on the outer surface of the discharge pipe 5, and a movable plate 7 movably mounted on the outer surface of the discharge pipe 5 and at the top of the fixing plate 16. Limiting posts 17 are fixedly connected to both sides of the lower surface of the mixing tank 3. The bottom end of the limiting post 17 passes through the fixing plate 16 and is fixedly connected to the bottom plate 6. A reset spring 18 is installed on the outer surface of the limiting post 17. A sealing gasket 14 is installed on the lower surface of the sealing plate 13. The sealing plate 13 and the sealing gasket 14 are located at the bottom of the inner wall of the mixing tank 3. The discharge pipe 5 has an internal hollow structure. Multiple through holes 19 are opened on the outer side of the top of the connecting post 15. A discharge port 20 is opened on the lower surface of the bottom plate 6. The discharge port 20 is connected to the through holes 19 through the hollow structure space inside the connecting post 15.

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

[0021] When gel filling is required for the battery cell, the battery cell can be placed inside the battery casing first, and then positioned below the discharge pipe 5 in the device. By using the drive motor 4 to drive the stirring shaft 11 to rotate, the stirring rod 12 can be rotated, thus stirring the gel inside the stirring tank 3. When it is necessary to discharge the material, the bottom plate 6 can be pushed upwards. The bottom plate 6 drives the movable plate 7 to move upwards through the limiting post 17.

[0022] The two return springs 18 are squeezed, which causes the connecting column 15 and the sealing plate 13 to move upward. The part of the connecting column 15 with the through hole 19 moves into the mixing tank 3. The gel flows into the interior of the connecting column 15 through the through hole 19 and is discharged through the discharge port 20, thereby completing the gel filling of the battery cell.

[0023] 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.
