Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a slurry transfer device. Background Art

[0002] A soft-pack lithium battery is another name for a polymer battery. Compared with a lithium-ion battery, it has various advantages such as small size, light weight, high specific energy, high safety, and flexible design.

[0003] Specifically, the soft-pack lithium battery has the following advantages: 1. Good safety performance: The soft-pack lithium battery is packaged with an aluminum-plastic film in terms of structure. In the case of potential safety hazards, the soft-pack lithium battery will at most bulge and crack, rather than explode like a steel-shell or aluminum-shell battery cell; 2. Light weight: The soft-pack lithium battery is 40% lighter than a steel-shell lithium battery of the same capacity and 20% lighter than an aluminum-shell battery; 3. Large capacity: The soft-pack lithium battery has a capacity 10-15% higher than that of a steel-shell battery of the same specification size and 5-10% higher than that of an aluminum-shell battery; 4. Small internal resistance: The internal resistance of the soft-pack lithium battery is smaller than that of a lithium battery. Currently, the internal resistance of domestic soft-pack lithium battery cells can be minimized to below 35 mΩ, greatly reducing the self-power consumption of the battery; 5. Flexible design: The shape of the soft-pack lithium battery can be customized according to customer requirements to develop new battery cell models.

[0035] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0036] Referring to Figures 1 - 6 As shown, the present invention provides a slurry transfer device for transferring and introducing a slurry with fluidity and corrosiveness into the soft shell of a lithium battery during the production process of a soft-pack lithium battery.

[0037] The slurry transfer device includes a loading part 1 and a switching part 2. As Figure 1 and Figure 2 shown, the loading part 1 includes a cylindrical member 11 and a sealing member 12. The sealing member 12 is rotationally connected to the cylindrical member 11 around a rotation axis. Specifically, for example, the air outlet member 12 can be passed through a rotating shaft 13, and the rotating shaft 13 can be installed on the cylindrical member 11 to open and close the discharge port of the cylindrical member 11.

[0038] The sealing member 12 includes a light part 121 and a weight part 122. As Figure 4 shown, the weight of the weight part 122 is greater than the weight of the light part 121. The light part 121 and the weight part 122 are arranged on both sides of the rotation axis. In a free state, the sealing member 12 opens the discharge port of the cylindrical member 11. Preferably, the light part 121 and the weight part 122 are integrally formed. Of course, the weight part 122 can also include weight blocks to ensure that the weight of the weight part 122 is greater than the weight of the light part 121.

[0039] The switch part 2 is connected to the loading part 1. When the switch part 2 acts on the light part 121, the sealing component 12 closes the discharge port of the cylindrical component 11; when the switch part 2 disengages from the light part 121, the sealing component 12 opens the discharge port of the cylindrical component 11 under the action of the offset of its own center of gravity.

[0040] The switch part 2 includes a abutting part 21, as Figure 5 shown, the abutting part 21 can move along the axial direction of the cylindrical component 11, the abutting part 21 can abut against the light part 121 of the sealing component 12, and the abutting part 21 is arranged on the side of the sealing component 12 facing the inner side of the cylindrical component 11. When the abutting part 21 moves along the axial direction of the cylindrical component to the limit position near the discharge port end, the sealing component 12, under the action of its own gravity, makes the light part 121 abut against the abutting part 21, thereby closing the discharge port of the cylindrical component 11.

[0041] The switch part 2 further includes a transmission part 22, as Figure 5 shown, the transmission part 22 is connected to the abutting part 21; a first mounting part 111 is provided on the side wall of the cylindrical component 11, as Figure 3 shown, the transmission part 22 is a long rod, and the material can be stainless steel. The first mounting part 111 is a long groove or a long hole provided on the inner side of the cylindrical component 11, and the transmission part 22 is slidably arranged in the first mounting part 111.

[0042] The switch part 2 further includes an operating part 23, as Figure 5 shown, a second mounting part 231 is provided on the operating part 23. The second mounting part 231 is a hole, and the second mounting part 231 is arranged at the end of the first mounting part 111 away from the discharge port. The end of the transmission part 22 away from the abutting part 21 extends out of the first mounting part 111 and is fixedly installed on the second mounting part 231 of the operating part 23.

[0043] The switch part 2 further includes an elastic part 24, as Figure 5 shown, a third mounting part 112 is provided on the side wall of the cylindrical component 11, as Figure 3As shown, the third mounting portion 112 is connected to the first mounting portion 111. The third mounting portion 112 is provided at one end of the first mounting portion 111 away from the discharge port. The third mounting portion 112 is a hole. A stepped surface is formed between the third mounting portion 112 and the first mounting portion 111. The elastic member 24 is installed in the third mounting portion 12. The transmission portion 22 is slidably disposed in the elastic member 24 and the first mounting portion 111. Finally, the operating member 23 is installed in the third mounting portion 112. One end of the elastic member 24 abuts against the stepped surface, and the other end abuts against the operating member 23.

[0044] The switch portion 2 further includes a locking member for keeping the abutting portion 21 continuously abutting against the sealing member 12.

[0045] The slurry transfer device further includes a drainage portion 3, as Figure 6 shown. The drainage portion 3 is provided with a fourth mounting portion 31. The loading portion 1 is disposed on the fourth mounting portion 31. The drainage portion 3 is used for draining the slurry transferred by the loading portion 1.

[0046] The drainage portion 3 includes a body portion 32, as Figure 6 shown. The body portion 32 has a frustum-shaped structure. The frustum-shaped structure 32 is provided with a hollow cavity. The inner region at the upper end of the hollow cavity of the frustum-shaped structure forms the fourth mounting portion 31. The loading portion 1 is installed on the fourth mounting portion 31. The body portion 32 being provided with a frustum-shaped structure enables the slurry transfer device to be applicable to different-diameter inlets of the battery soft package shell, making the feeding more convenient.

[0047] The drainage portion 3 further includes a collecting portion 33, as Figure 6 shown. The collecting portion 33 has an annular groove structure. The collecting portion 33 is disposed on the outer peripheral side of the large end of the body portion 32. The opening direction of the collecting portion 33 faces away from the small end of the frustum-shaped structure. The slurry adhering to the loading portion 1 can flow into the collecting portion 33, thereby avoiding falling on the ground, clothes, etc.

[0048] A guiding structure 34 is provided on the collecting portion 33, as Figure 6 shown. The annular groove structure communicates with the hollow cavity through the guiding structure 34 to guide the slurry in the collecting portion 33 into the hollow cavity of the body portion 32. In a specific embodiment, the guiding structure 34 is a guiding groove 341. The guiding groove 341 extends along the radial direction of the body portion 32. For example, four guiding grooves 341 are provided. In this way, the slurry collected on the collecting portion 33 can be guided into the hollow cavity of the body portion 32, reducing slurry waste and avoiding slurry overflow from the collecting portion 33.

[0049] For the slurry transfer device of the present invention, when transferring the device, operate the operating member 23 so that the abutting portion 21 abuts against the light portion 121 of the sealing member 12, thereby closing the discharge port of the cylindrical member 11. Place the loading portion 1 into the slurry. Under the action of the liquid, the counterweight portion 122 of the sealing member 12 rotates towards the inner portion of the cylindrical member 11, opening the discharge port. The slurry enters the cylindrical member 11 from the discharge port. Take out the loading portion 1. Under the action of the slurry in the cylindrical member 11 and the overweight of the sealing member 12, the sealing member 12 closes the discharge port of the cylindrical member 11, and the slurry is stored in the cylindrical member 11. Place the loading portion 1 on the fourth mounting portion 31 on the guiding portion 3. Operate the operating member 23, and the abutting portion 21 disengages from the light portion 121 of the sealing member 12. Under the action of the slurry in the cylindrical member 11 and the overweight of the sealing member 12, the sealing member 12 opens the discharge port of the cylindrical member 11, and the slurry flows out from the body portion 32. At the same time, the slurry adhering to the loading portion 1 gathers in the gathering portion 33 and flows out through the flow guiding groove 341 into the hollow cavity of the body portion 32.

[0050] The slurry transfer device of the present invention can avoid the dropping of the slurry, achieve a safer and more economical transfer of the slurry, and the loading method is more convenient to operate, and can be applicable to the feeding ports with different diameters of the battery soft package shell.

[0051] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above preferred solutions can be freely combined and superimposed.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
