Description

Technical Field

[0001] The present application relates to the technical field of battery separator production, and in particular to a separator casting forming production system and method. Background Art

[0002] Lithium-ion batteries are representatives of modern high-performance batteries and are composed of four main parts: a positive electrode material, a negative electrode material, a separator, and an electrolyte. Among them, the separator is a thin film with a microporous structure and is a key inner-layer component with higher technical barriers in the lithium-ion battery industrial chain. It plays the following two main roles in lithium batteries: a. Separating the positive and negative electrodes of the lithium battery to reduce the possibility of short circuit formation due to contact between the positive and negative electrodes; b. The micropores in the thin film allow lithium ions to pass through, forming a charge and discharge circuit.

[0003] A casting system refers to a special device for making a cast film. The casting system is also an important device for producing lithium battery separators. Generally, when producing lithium battery separators with a casting system, the raw materials need to be melted, extruded through an extruder, and then tensioned through multiple tension rollers. Each tension roller is provided with a water-cooling cycle. After tensioning and cooling to form a lithium battery separator, in order to reduce damage to the lithium battery separator, a winding device is required for winding operation to store the lithium battery separator. The winding device includes a driveable winding roller, and a winding cylinder is sleeved on the winding roller. During winding, one end of the lithium battery separator is wound around the winding cylinder, and then the winding cylinder is rotated to wind the lithium battery separator.

[0004] In view of the above related technologies, during the winding process of the lithium battery separator, when the end of the lithium battery separator is wound around the winding cylinder, there may be a possibility of stacking and wrinkling, resulting in greater waste, and may also cause surface wrinkles during the winding of the lithium battery separator, and the winding quality is poor. Summary of the Invention

[0005] In order to facilitate winding the lithium battery separator tightly and flatly on the winding roller and improve the winding quality of the lithium battery separator, the present application provides a separator casting forming production system and method.

[0006] In a first aspect, a separator casting forming production system provided by the present application adopts the following technical solution:

[0007] A diaphragm casting forming production system, wherein the conveying component is arranged at the discharge port of the casting machine, and a winding component is arranged on the side of the conveying component away from the casting machine. The conveying component is used to convey the diaphragm to the winding component through the casting machine; the winding component includes a mounting frame, a first winding member and a second winding member. The mounting frame is arranged on the side of the conveying component away from the casting machine. The first winding member is rotatably connected to the mounting frame. The first winding member is used to adsorb and wind the diaphragm. There are a plurality of adsorption grooves on the first winding member. A winding drum is sleeved on the first winding member. A plurality of first adsorption ports are arranged at intervals along the rotation axis of the winding drum. The plurality of first adsorption ports are in one-to-one correspondence and communication with the plurality of adsorption grooves; the second winding member is located on one side of the first winding member and is slidably connected to the mounting frame. The second winding member is used to adsorb the diaphragm. The end of the second winding member is connected with a lifting drive, and the lifting drive is used to drive the second winding member to approach or move away from the first winding member. A cutting member is also arranged on one side of the first winding member, and the cutting member is used to cut off the diaphragm between the conveying component and the first winding member.

[0008] By adopting the above technical solution, the diaphragm produced by the casting machine enters the winding component through the conveying component. During winding, the end of the diaphragm is adsorbed by the second winding member. The lifting drive is started to drive the second winding member to approach the first adsorption port on the winding drum. The first winding member is started to adsorb the diaphragm. When the first winding member is started, a negative pressure is formed in the adsorption grooves. At this time, a negative pressure is formed in the first adsorption port of the winding drum, so as to adsorb the diaphragm on the winding drum. Then, the adsorption of the diaphragm by the second winding member is released, and the first winding member is started to wind the diaphragm. After the winding is completed, the second winding member is started again to adsorb the end of the diaphragm. Then, the cutting member is used to cut off the diaphragm, so that the diaphragm is flatly adsorbed on the second winding member. After waiting for the first winding member to replace the winding drum, the above steps of adsorbing the diaphragm on the first winding member for winding are repeated again, so as to facilitate winding the diaphragm flatly and tightly on the winding roller and improve the winding quality of the diaphragm.

[0009] Optionally, the mounting frame includes two mounting plates symmetrically arranged along the conveying direction of the conveying component. The first winding member includes a first winding roller, a first negative pressure member and a rotation drive. Both ends of the first winding roller are rotatably connected to the mounting plates. A plurality of adsorption grooves are arranged at intervals along the rotation axis of the first winding roller. The first negative pressure member is communicated with the first winding roller, and the first negative pressure member is used to form a negative pressure in the first winding roller. The rotation drive is arranged at one end of the first winding roller, and the rotation drive is used to drive the first winding roller to rotate.

[0010] By adopting the above technical solution, when winding the diaphragm, first start the first negative pressure member. The first negative pressure member forms a negative pressure in the first winding roller, and adsorbs the diaphragm through the first adsorption port. Then start the rotation drive, and the rotation drive drives the first winding roller to rotate, so that the diaphragm is flatly wound on the winding drum.

[0011] Optionally, a placement groove is provided at a position of any of the mounting plates close to the first winding roller. An installation block is rotatably connected in the placement groove. One end of the first winding roller is rotatably connected to the installation block. One end of the installation block is rotatably connected to a pushing drive. The pushing drive is used to push the installation block to rotate. A receiving groove is provided on another mounting plate away from the placement groove. The first winding roller can enter or disengage from the receiving groove.

[0012] By adopting the above technical solution, when replacing the winding cylinder, start the pushing drive. The pushing drive drives the installation block to rotate, so that the installation block drives the first winding roller to rotate while rotating, until one end of the first winding roller located in the receiving groove disengages from the supporting groove, take out the wound winding cylinder, replace it with a new winding cylinder, and start the pushing drive again. The pushing drive drives the installation block to rotate until one end of the first winding roller located in the receiving groove enters the supporting groove.

[0013] Optionally, the second winding member includes a second winding roller and a second negative pressure member. A plurality of second adsorption ports are provided on the second winding roller. A signal transmitter is provided on the side wall of one end of the second winding roller. A signal receiver is provided on the side wall of one end of the winding paper tube. The signal receiver is used to receive the signal emitted by the signal transmitter when it is opposite to the signal transmitter. The second negative pressure member is connected to the second winding roller. The second negative pressure member is used to form a negative pressure inside the second winding roller.

[0014] By adopting the above technical solution, when installing the winding cylinder, align the signal receiver and the signal transmitter so that the second adsorption port corresponds to the first adsorption port, which is convenient for transferring the diaphragm from the second winding roller to the winding cylinder.

[0015] Optionally, sliding grooves are provided on one side of each mounting plate close to the second winding roller. The extending direction of the sliding grooves is the same as the height direction of the mounting plate. Sliding blocks are provided at both ends of the second winding roller. The second winding roller is rotatably connected to the sliding blocks. The sliding blocks are located in the sliding grooves and can slide along the sliding grooves. A lifting drive is arranged on one side of the second winding roller and connected to the mounting plate. A telescopic member is arranged between the lifting drive and the second winding roller. One end of the telescopic member is fixedly connected to the second winding roller, and the other end is rotatably connected to the lifting drive.

[0016] By adopting the above technical solution, when aligning the first adsorption port and the second adsorption port, start the telescopic member and the lifting drive. As the telescopic distance of the telescopic member increases, the second winding roller is driven to rotate. When the signal receiver is aligned with the signal transmitter, the first adsorption port faces the second adsorption port. Fix the telescopic length of the telescopic member, and continue to use the lifting drive to drive the telescopic member to rise until the second adsorption port is close to the first adsorption port, which is convenient for transferring the diaphragm from the second adsorption port to the first adsorption port.

[0017] Optionally, the telescopic member includes a first telescopic rod and a second telescopic rod. The first telescopic rod is slidably connected to the second telescopic rod. One end of the first telescopic rod away from the second telescopic rod is fixedly connected to the second winding roller. One end of the second telescopic rod away from the first telescopic rod is rotatably connected to the lifting drive. A fixing member is provided on the first telescopic rod, and the fixing member is used to relatively fix the first telescopic rod and the second telescopic rod.

[0018] By adopting the above technical solution, when the lifting drive drives the telescopic member upward, the lifting drive drives one end of the second telescopic rod away from the first telescopic rod to rotate with the lifting drive. The second telescopic rod drives the first telescopic rod to rotate, and the first telescopic rod drives the second winding roller to rotate, so that the signal receiver is aligned with the signal transmitter. After alignment, the fixing member fixes the first telescopic rod and the second telescopic rod, and the lifting drive continuously pushes up the second telescopic member to drive the second winding roller closer to the first winding roller.

[0019] Optionally, the fixing member includes an electromagnetic strip and an electromagnetic block. The electromagnetic strip and the electromagnetic block are respectively embedded in the first telescopic rod and the second telescopic rod, and the electromagnetic strip and the electromagnetic block can adsorb each other.

[0020] By adopting the above technical solution, when fixing the first telescopic rod and the second telescopic rod, the electromagnetic strip and the electromagnetic block are started to make the electromagnetic strip and the electromagnetic block adsorb each other, and the fixing of the first telescopic rod and the second telescopic rod is completed.

[0021] Optionally, a receiving plate is provided on the mounting plate at the receiving groove.

[0022] By adopting the above technical solution, the receiving plate is used to place the first winding roller separated from the receiving groove, reducing the possibility that the mounting block is easily deformed due to the overweight of the first winding roller.

[0023] On the other hand, the present application also provides an operation method applicable to a diaphragm casting production system as described above.

[0024] A method for using a diaphragm casting production system, and its operation method is as follows:

[0025] Start the casting machine to produce the diaphragm;

[0026] The diaphragm enters the winding assembly through the conveying assembly;

[0027] During winding, the second winding member adsorbs the end of the diaphragm. After adsorbing the diaphragm, the lifting drive drives the second winding member closer to the first winding member;

[0028] After the second winding member approaches the first winding member, the end of the diaphragm approaches the first adsorption port of the winding cylinder, and the first winding member adsorbs the end of the diaphragm. The second winding member releases the adsorption of the diaphragm, and the transfer of the diaphragm is completed;

[0029] Rotate the first winding member. After the diaphragm winding is completed, the second winding member approaches the first adsorption port again to adsorb the diaphragm. At this time, the cutting member cuts the diaphragm;

[0030] Replace the paper tube on the first winding member and repeat the above process of transferring the diaphragm.

[0031] By adopting the above technical solution, the produced diaphragm is first adsorbed on the second winding member. The second winding member transfers the flattened diaphragm to the winding drum. The first winding member adsorbs the diaphragm near the winding drum, so that the diaphragm is wound flat and tightly on the winding roller.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. By arranging a winding assembly at one end of the conveying assembly, the second winding member in the winding assembly adsorbs the diaphragm flatly. After adsorption, the diaphragm is transferred into the winding drum on the first winding member. When replacing the winding drum after winding is completed, the cut end of the diaphragm is adsorbed by the second winding member. After replacing the winding drum, the diaphragm on the second winding member is transferred to the newly replaced winding drum, which is convenient for winding the diaphragm flat and tightly on the winding roller and improving the winding quality of the diaphragm;

[0034] 2. By arranging the telescopic member and the lifting drive, the lifting drive can drive the telescopic member to rotate and lift the second winding roller, align the second adsorption port with the first adsorption port and make them approach each other after alignment, which is convenient for transferring the diaphragm.

Detailed implementation manners

[0042] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 drawings.

[0043] An embodiment of the present application discloses a diaphragm casting forming production system.

[0044] Referring to Figure 1 , a diaphragm casting forming production system includes a casting machine 1 and a conveying assembly 2. The conveying assembly 2 is arranged at the discharge port of the casting machine 1. The casting machine 1 is a casting film forming machine, and the conveying assembly 2 is a conveyor provided with a plurality of conveying rollers. A winding assembly 3 is arranged on the side of the conveying assembly 2 away from the casting machine 1. The conveying assembly 2 is used to convey the diaphragm to the winding assembly 3 via the casting machine 1.

[0045] Referring to Figure 1 , Figure 2 , the winding assembly 3 includes a mounting frame 31, a first winding member 32 and a second winding member 33. The mounting frame 31 includes two mounting plates 311 symmetrically arranged along the conveying direction of the conveying assembly 2. Both mounting plates 311 are fixedly connected to one end of the conveying assembly 2 away from the casting machine 1 by bolts.

[0046] Referring to Figure 2 , Figure 3The first winding member 32 is rotatably connected to the mounting frame 31. The first winding member 32 is used to absorb and roll up the diaphragm. The first winding member 32 is a negative pressure winding roller. The second winding member 33 is located below the first winding member 32 and is slidably connected to the mounting frame 31. The sliding direction is close to or away from the first winding member 32. The second winding member 33 is also a negative pressure winding roller. The second winding member 33 is used to absorb the diaphragm. The end of the second winding member 33 is connected to a lifting drive 34. The lifting drive 34 is used to drive the second winding member 33 to approach or move away from the first winding member 32.

[0047] When the diaphragm is rolled up, the second winding member 33 flattens and absorbs the end of the diaphragm, and the diaphragm absorbed by the second winding member 33 can be transferred to the first winding member 32 for rolling up. After the rolling is completed, before cutting the diaphragm, the second winding member 33 is close to the part of the diaphragm that needs to be cut and absorbs the diaphragm. After the second winding member 33 absorbs the diaphragm, it cuts the diaphragm, takes out the diaphragm that has been rolled up by the first winding member 32, and transfers the diaphragm to the first winding member 32 for rolling up the diaphragm, thereby reducing the possibility of the diaphragm stacking after cutting the diaphragm and rolling it up at the first winding member 32, making it easier to roll the diaphragm flat and tightly on the winding roller, thereby improving the rolling quality of the diaphragm.

[0048] Reference Figure 2 , Figure 3 The first winding member 32 includes a first winding roller 321, a first negative pressure member and a rotation drive 323. A placement groove 3111 is opened at a position near the first winding roller 321 on any mounting plate 311.
