Description

Technical Field

[0001] The utility model relates to the field of lithium batteries, in particular to a lithium battery diaphragm layering machine. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the overall performance of the battery. The diaphragm is made of plastic film, which can isolate the positive and negative poles of the battery to prevent short circuits. It can also block the current conduction in the battery through the closed-cell function when the battery is overheated. The diaphragm is simply a layer of porous plastic film, which is a high-value-added material with the highest technical barriers among lithium battery materials, accounting for about 20%-30% of the cost of lithium batteries.

[0003] Due to the thickness requirement of the diaphragm, the diaphragm needs to be layered again. The current diaphragm layering machine will first fix the diaphragm roll on the placement rack and then pull the diaphragm forward during layering. When the diaphragm roll needs to be replaced, the diaphragm roll needs to be removed and then replaced with a new diaphragm. This method is relatively cumbersome and affects work efficiency.

[0004] Based on this, we need to design a lithium battery diaphragm layering machine that is convenient for replacing diaphragm rolls. Utility Model Content

[0005] In order to overcome the disadvantage that when the diaphragm roll needs to be replaced, the diaphragm roll needs to be disassembled and then replaced with a new diaphragm, which is cumbersome and affects work efficiency, the utility model provides a lithium battery diaphragm layering machine that is convenient for replacing the diaphragm roll.

[0006] The technical solution of the utility model is as follows: a lithium battery diaphragm stratification machine, comprising a stratification machine, a first support seat, a mounting frame, a first motor, a rotating disk, a support frame and a cylinder, the first support seat is installed on one side of the stratification machine, the mounting frame is installed on the upper part of the first support seat, the first motor is installed on one side of the mounting frame, the rotating disk is symmetrically installed on both sides of the mounting frame, the cylinder is symmetrically installed on both sides of the rotating disk, and the support frame is installed on one side of the cylinder.

[0007] Preferably, it also includes a second support base, a second motor and a transmission assembly. The second support base is symmetrically installed on the front of the first support base, a second motor is installed on one side of the second support base, and a transmission assembly is movably installed on the second support base. One end of the transmission assembly is connected to the output shaft of the second motor through a coupling.

[0008] Preferably, a protective cover is also included, and the outer part of the transmission component is covered with the protective cover.

[0009] Preferably, a collecting frame is further included, and the collecting frame is movably installed inside the first supporting seat.

[0010] Preferably, a rotating cover is further included, and the rotating cover is installed on the upper part of the mounting frame.

[0011] Preferably, a connecting rod is further included, and the connecting rod is symmetrically installed on the upper and lower sides of the rotating disk.

[0012] The beneficial effect of the utility model is that by driving the cylinders, the cylinders on both sides are pushed inward to clamp the diaphragm. When replacing the diaphragm roll, the cylinders can be driven rearward, and the diaphragm can be taken out when the cylinders are opened, thereby achieving the effect of convenient replacement of the diaphragm.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] A lithium battery separator laminating machine, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a layering machine 1, a first support seat 2, a mounting frame 3, a first motor 4, a rotating disk 5, a support frame 501, a connecting rod 6 and a cylinder 7. The first support seat 2 is installed on the front side of the layering machine 1, and the mounting frame 3 is installed on the upper part of the first support seat 2. The first support seat 2 plays a role of supporting the mounting frame 3. The first motor 4 is installed on the right side of the mounting frame 3. The rotating disk 5 is symmetrically installed on both sides of the mounting frame 3. The rotating disk 5 rotates a certain angle to facilitate the removal of the diaphragm. The connecting rods 6 are symmetrically installed above and below the rotating disk 5. The connecting rods 6 drive the two rotating disks 5 to rotate. The cylinders 7 on both sides are symmetrically installed on both sides of the rotating disk 5. The cylinders 7 on both sides push inward to clamp the diaphragm. The support frame 501 is installed on the right side of the cylinder 7. The support frame 501 plays a role of supporting the diaphragm.

[0023] When the diaphragm is close to the rotating disk 5, the diaphragm is manually moved to clamp it on the support frame 501, and then the cylinder 7 is driven to push the cylinders 7 on both sides inward to clamp the diaphragm, and then the two diaphragms are pulled forward respectively to the upper part of the stratification machine 1 for stratification. However, when the diaphragm roll needs to be replaced, the cylinder 7 can be driven backward, and the diaphragm can be taken out when the cylinder 7 is opened, thereby achieving the effect of convenient replacement of the diaphragm.

[0024] Example 2

[0025] On the basis of Example 1, Figure 5 and Figure 6 As shown, it also includes a second support seat 8, a second motor 9, a transmission assembly 10, a protective cover 11, a collection frame 12 and a rotating cover 13. The second support seat 8 is symmetrically installed on the front of the first support seat 2, and the second motor 9 is installed on the left side of the second support seat 8. The transmission assembly 10 is movably installed on the second support seat 8, and the left end of the transmission assembly 10 is connected to the output shaft of the second motor 9 through a coupling. The outside of the transmission assembly 10 is covered with a protective cover 11, and the protective cover 11 plays a role in protecting the transmission assembly 10. The inside of the first support seat 2 is movably installed with a collection frame 12, and the collection frame 12 stores garbage after the diaphragm is used up. The upper part of the mounting frame 3 is installed with a rotating cover 13, and the rotating cover 13 plays a role in protecting the first support seat 2.

[0026] When the staff uses this design, they first place the diaphragm on the conveying assembly 10, and then drive the second motor 9. The second motor 9 drives the conveying assembly 10 to rotate, and at the same time drives the diaphragm to be transported forward. After the diaphragm roll is used, the paper roll falls into the collection frame 12, and then the collection frame 12 is pulled to take out the paper roll.

It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
