Description

Technical Field

[0001] The present invention relates to the field of lithium batteries, and in particular to a lithium-ion battery diaphragm water washing tank device. Background Art

[0002] During the production of lithium-ion batteries, the lithium battery diaphragm needs to be oiled. For the oily lithium battery diaphragm, it is usually necessary to pass through a water washing tank for water washing to solidify and form. The diaphragm water washing process requires the diaphragm to be completely immersed in the liquid. The traditional method is to install the water washing section roller in the water washing tank, and the diaphragm passes through the water washing roller for water washing. In this way, the parallelism between the water washing rollers cannot be accurately guaranteed, and the cleaning of the water washing tank and the water washing roller is inconvenient, and the subsequent cleaning is quite cumbersome. Summary of the invention

[0003] Based on the above, the present invention provides a lithium-ion battery diaphragm washing tank device to solve the problem that the parallelism of the existing diaphragm washing cannot be guaranteed and the subsequent cleaning of the washing tank is cumbersome.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] A lithium-ion battery diaphragm washing tank device comprises a diaphragm drive conveying device, a diaphragm drive output device, a diaphragm washing roller group, a washing tank, a device support and a lifting support, wherein the diaphragm drive conveying device and the diaphragm drive output device are respectively located at two ends of the device support, the diaphragm washing roller group is located between the diaphragm drive conveying device and the diaphragm drive output device, the head end of which is connected to the diaphragm drive conveying device, and the tail end of which is connected to the diaphragm drive output device, the washing tank is located directly below the diaphragm washing roller group, and the lower end of which is supported by the washing tank lifting frame and moves up and down.

[0006] As a preferred embodiment of the present invention, the diaphragm drive conveying device and the diaphragm drive output device are provided with a clamping device for ensuring the parallelism between the diaphragm output and input.

[0007] As a preferred embodiment of the present invention, a plurality of roller groups are arranged in the membrane washing roller group, and the plurality of roller groups are divided into an upper and a lower double layer, and the membrane is wound around the plurality of roller groups in an S shape.

[0008] As a preferred embodiment of the present invention, a support plate for ensuring the parallelism of the diaphragm is provided in the water washing tank.

[0009] As a preferred embodiment of the present invention, the lifting bracket is a hydraulic lift, and an auxiliary support rod is provided at the middle portion of the lifting bracket.

[0010] As a preferred embodiment of the present invention, a pre-treatment and leveling device is provided at the rear end of the pressing device on the diaphragm driven conveying device.

[0011] The beneficial effects of the present invention are:

[0012] The lithium-ion battery diaphragm washing tank device designed in the present invention mainly deals with the parallelism problem of diaphragm washing and the cleaning problem of the washing tank. A diaphragm driving and conveying device and a washing tank that can be driven up and down are arranged at the head end of the entire device. Since the diaphragm does not need to move up and down, its parallelism can be better solved, and the washing tank can be raised and lowered, which is convenient for later cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments of the present invention.

[0014] Figure 1 This is a diagram of a preparatory state of a lithium-ion battery diaphragm washing tank device provided in an embodiment of the present invention;

[0015] Figure 2 This is a working state diagram of a lithium-ion battery diaphragm washing tank device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0016] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 2 As shown, this embodiment provides a lithium-ion battery diaphragm washing tank device, which mainly includes a diaphragm drive conveying device 1, a diaphragm drive output device 2, a diaphragm washing roller group 3, a washing tank 4, a device bracket 5 and a lifting bracket 6. The diaphragm drive conveying device 1 and the diaphragm drive output device 2 are respectively located at the two ends of the device bracket 5, the diaphragm washing roller group 3 is located between the diaphragm drive conveying device 1 and the diaphragm drive output device 2, its head end is connected to the diaphragm drive conveying device 1, and its tail end is connected to the diaphragm drive output device 2, the washing tank 4 is located directly below the diaphragm washing roller group 3, and its lower end is supported by the washing tank lifting frame and can move up and down. It can be seen from here that when the diaphragm is washed, the water washing tank 4 in this embodiment rises upward to complete the washing process of the diaphragm, while the traditional water washing tank and diaphragm water washing roller are both stationary, and the diaphragm water washing roller is installed in the water washing tank, so the diaphragm needs to be passed through the water washing roller underwater for operation, but the parallelism of the diaphragm in this way is difficult to guarantee, and the cleaning of the water washing tank and the diaphragm water washing roller is relatively difficult, while the water washing tank and the diaphragm water washing roller in this embodiment can be disconnected and firmly fixed after installation. Since the diaphragm does not need to move up and down, its parallelism can be better solved, and the water washing tank can be raised and lowered, which is convenient for later cleaning and maintenance.

[0018] In this embodiment, a clamping device 7 is provided on the diaphragm drive conveying device 1 and the diaphragm drive output device 2 to ensure the parallelism of the input and output of the diaphragm. In addition, a support plate 8 is provided on the front and rear sides of the washing tank 4, and the support plate 8 further ensures the parallelism of the diaphragm. In this embodiment, multiple groups of rollers 9 are provided in the diaphragm washing roller group 3, and the multiple groups of rollers 9 are divided into upper and lower double layers. The diaphragm is wound on the multiple groups of rollers 9 in an S shape, which can accommodate more diaphragms in a smaller space and shorten the washing cycle. The lifting bracket 6 in this embodiment uses a hydraulic lift, and a support rod 10 is provided at the middle part of the lifting bracket 6 for auxiliary support to improve the stability during lifting. The rear end of the clamping device 7 on the diaphragm drive conveying device 1 is provided with a pre-treatment leveling device 11, and the pre-treatment leveling device 11 is used to perform parallelism treatment on the diaphragm before it enters the multiple groups of rollers 9.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
