Description

Hot composite roller cleaning device and battery processing equipment

[0001] This application claims priority to Chinese Patent Application No. 202422932292.4, filed with the Chinese Patent Office on November 28, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of battery processing technology, and in particular to a hot composite roller cleaning device and battery processing equipment. Background Technology

[0003] In battery manufacturing, a thermal bonding process is required to thermally bond the separator and electrode sheets. Specifically, the rolling rollers are first heated, and then used to roll the separator and electrode sheets together, achieving thermal bonding and adhesion. Invention Overview

[0004] However, in actual production, ceramics and composite adhesives on the diaphragm may adhere to the rolling rollers, which can lead to indentations on the electrodes and diaphragms during subsequent rolling processes, thus reducing the yield of the core package and increasing costs.

[0005] This application proposes a hot composite roller cleaning device that can reduce indentations on electrodes and diaphragms, improve core package yield, and save costs.

[0006] In a first aspect, this application provides a thermal composite roller cleaning device, comprising:

[0007] The body is configured to be disposed on one side of the thermal composite roller;

[0008] The body includes a first arc surface and a second arc surface, both of which are arranged facing the thermal composite roller. A first air intake and a first air blowing port are provided on the first arc surface, and a second air intake and a second air blowing port are provided on the second arc surface. The distance between the first air blowing port and the second air blowing port is less than the distance between the first air intake and the second air intake.

[0009] Secondly, this application proposes a battery processing apparatus, which includes the thermal composite roller cleaning device as described in any of the above claims. Beneficial effects

[0010] The beneficial effects of this application are:

[0011] The thermal laminating roller cleaning device provided in this application includes a first air inlet and a second air inlet, both configured to blow air onto the adhesive material on the thermal laminating roller, and a first air suction inlet and a second air suction inlet, both configured to suck up the adhesive material. The first and second air inlets are configured to blow air onto the adhesive material on the thermal laminating roller, allowing the adhesive material to be blown off the roller. The first and second air suction inlets are configured to suck up the adhesive material blown off the thermal laminating roller, allowing the adhesive material to be removed. The distance between the first and second air inlets is less than the distance between the first and second air intakes. In other words, both the first and second air inlets are located in the middle of the body, while both the first and second air intakes are located at the edge of the body. This creates a negative pressure zone on both sides of the first and second air inlets (i.e., the locations of the first and second air intakes) when air is blown through them. This allows the adhesive to be sucked away, ensuring the cleanliness of the roller surface of the thermal composite roller. It also prevents indentations on the electrode and diaphragm when the thermal composite roller is pressing them, thus improving the product yield of the core package and achieving cost savings.

[0020] This application provides a hot composite roller cleaning device that can reduce indentations on electrodes and diaphragms, improve core package yield, and save costs.

[0021] As shown in Figures 1-3, the thermal composite roller cleaning device mainly includes a body 100. The body 100 is configured to be disposed on one side of the thermal composite roller 200. Specifically, the body 100 includes a first arc surface 110 and a second arc surface 120, both of which face the thermal composite roller 200. The first arc surface 110 is provided with a first air intake 130 and a first air blowing port 150, and the second arc surface 120 is provided with a second air intake 140 and a second air blowing port 160. The distance between the first air blowing port 150 and the second air blowing port 160 is less than the distance between the first air intake 130 and the second air intake 140. The first air blowing port 150 and the second air blowing port 160 are both configured to blow air onto the adhesive on the thermal composite roller 200, and the first air intake port 130 and the second air intake port 140 are both configured to suck up the adhesive.

[0022] Based on the above design, the first air inlet 150 and the second air inlet 160 are configured to blow air onto the adhesive on the thermal composite roller 200, so that the adhesive can be blown away from the thermal composite roller 200. The first air inlet 130 and the second air inlet 140 are both configured to suck up the adhesive blown away from the thermal composite roller 200, so that the adhesive can be sucked away. The distance between the first air inlet 150 and the second air inlet 160 is less than the distance between the first air inlet 130 and the second air inlet 140. In other words, the first air inlet 150 and the second air inlet 160 are both located in the middle of the body 100, and the first air inlet 130 and the second air inlet 140 are both located at the edge of the body 100. In this way, when the first air inlet 150 and the second air inlet 160 blow air, a negative pressure area can be formed on both sides of the first air inlet 150 and the second air inlet 160 (i.e., the positions of the first air inlet 130 and the second air inlet 140), so that the adhesive can be sucked away, thereby ensuring the cleanliness of the roller surface of the thermal composite roller 200, avoiding the phenomenon of indentation on the electrode and diaphragm when the thermal composite roller 200 is rolling the electrode and diaphragm, improving the product yield of the core package, and achieving the purpose of saving costs.

[0023] In some possible implementations, the body 100 is positioned above the thermal composite roller 200, which allows the thermal composite roller 200 to provide some support for the body 100, reduces the number of connecting parts between the thermal composite roller 200 and the body 100, simplifies the structure, and facilitates later disassembly and maintenance.

[0024] In some possible implementations, there can be multiple first air inlets 150 and multiple second air inlets 160, and there can be multiple first air inlets 130 and multiple second air inlets 140.

[0025] The first arc surface 110 and the second arc surface 120 in the technical solution of this application can improve the compatibility between the body 100 and the thermal composite roller 200, facilitate assembly, avoid interference between the body 100 and the thermal composite roller 200, and improve installation efficiency.

[0026] In some possible implementations, there is a first gap between the first arc surface 110 and the roller surface of the thermal composite roller 200, and a second gap between the second arc surface 120 and the roller surface of the thermal composite roller 200. The first gap and the second gap are equal. This ensures that the distances between the multiple first air outlets 150 and the multiple second air outlets 160 and the roller surface are kept as consistent as possible, so as to ensure that the airflow blown out by the multiple first air outlets 150 and the multiple second air outlets 160 exerts a relatively equal force on the adhesive, thus ensuring the cleaning efficiency of the adhesive.

[0027] In some possible implementations, the first air outlet 150 and the second air outlet 160 are both round holes or both are strip-shaped holes; the first air inlet 130 and the second air inlet 140 are both round holes or both are strip-shaped holes. In some possible implementations, the first air outlet 150 and the second air outlet 160 are both round holes, and the first air inlet 130 and the second air inlet 140 are both strip-shaped holes, and the area of ​​each round hole is smaller than the area of ​​each strip-shaped hole. This allows the adhesive to be sucked away by the larger strip-shaped holes as much as possible, while avoiding clogging the smaller round holes, thus improving the cleaning efficiency of the adhesive.

[0028] As shown in Figures 1 and 3, in some possible implementations, the main body 100 is provided with a third air intake 170, and a cavity 180 is provided inside the main body 100. One side of the cavity 180 is connected to both the first air intake 130 and the second air intake 140, and the other side of the cavity 180 is connected to the third air intake 170. The adhesive can be drawn into the cavity 180 through the first air intake 130 and the second air intake 140, and then moved from the cavity 180 to the third air intake 170 and discharged to the outside of the main body 100. The cavity 180 can form a certain storage space for the adhesive, improving cleaning efficiency.

[0029] In some possible implementations, as shown in Figure 1, the third air intake 170 has an outer edge 1701 that protrudes from the body 100. The hot composite roller cleaning device also includes an air intake assembly (not shown in the figure) and an air blowing assembly (not shown in the figure). The air intake assembly is connected to the third air intake 170 via the outer edge 1701, and the air blowing assembly is connected to both the first air blowing port 150 and the second air blowing port 160. The outer edge 1701 improves the stability and reliability of the connection between the third air intake 170 and the air intake assembly, reduces the possibility of them becoming loose, and improves installation efficiency.

[0030] In some possible implementations, the suction component can be configured as a negative pressure pump, and the blowing component as a positive pressure pump. Of course, operators can also choose other devices capable of blowing and suction, which will not be elaborated here.

[0031] As shown in Figures 4 and 5, this application also provides a battery processing equipment, which includes a thermal composite roller 200, a mounting base 300, a first drive assembly 400, and the aforementioned thermal composite roller cleaning device. The thermal composite roller 200 is installed in the mounting base 300, and the first drive assembly 400 is drivenly connected to the thermal composite roller 200 so that the first drive assembly 400 drives the thermal composite roller 200 to rotate; the thermal composite roller cleaning device is mounted on the mounting base 300.

[0032] Specifically, the main body 100 is provided with support parts 190 on opposite sides. The support parts 190 are configured to overlap the mounting base 300 of the thermal composite roller 200, which is convenient to operate, has high work efficiency, and does not require bolts, screws or other fasteners for installation, reducing costs and facilitating the maintenance and replacement of the thermal composite roller cleaning device in the later stage.

[0033] In some possible implementations, the first drive component 400 can be configured as a motor, which drives the thermal composite roller 200 to rotate, thereby realizing the thermal composite process of the diaphragm and the electrode.

[0034] In some possible implementations, there may be multiple first drive components 400 and thermal composite rollers 200, and each first drive component 400 and thermal composite roller 200 may be configured in a one-to-one correspondence.

[0035] As shown in Figures 4 and 5, the battery processing equipment also includes a second drive assembly 500, a lead screw 600, connecting parts 310, and a scraper assembly 700. Two connecting parts 310 are positioned facing each other, and both are connected to the mounting base 300. The two ends of the lead screw 600 are independently rotatably connected to the two connecting parts 310. The second drive assembly 500 is driven by the lead screw 600 to rotate, and the lead screw 600 is located directly above the hot composite roller 200. The scraper assembly 700 is connected to the lead screw 600. Thus, the second drive assembly 500 drives the lead screw 600 to rotate, and the rotation of the lead screw 600 drives the scraper assembly 700 on the lead screw to move back and forth. Specifically, the second drive assembly 500 drives the lead screw 600 to rotate by rotating forward and backward, thereby realizing the reciprocating motion of the scraper assembly 700, which increases the cleaning area of ​​the scraper assembly 700 on the roller surface and avoids the occurrence of cleaning dead zones.

[0036] In some possible implementations, the lead screw 600 is rotatably connected to the connector 310 via a bearing (not shown in the figure).

[0037] In some possible implementations, the second drive component 500 is configured as a motor, which drives the lead screw 600 to rotate forward or reverse to achieve the reciprocating motion of the scraper assembly 700.

[0038] It should be noted that, among these possible implementations, the scraper assembly 700 is a conventional component in the art, therefore, this application will not elaborate on its specific structure and working principle.

[0039] As shown in Figure 5, in some possible implementations, the battery processing equipment also includes a slide bar 800. Both ends of the slide bar 800 are independently connected to two connecting pieces 310. The slide bar 800 is located below the lead screw 600, and the scraper assembly 700 is slidably connected to the slide bar 800. The slide bar 800 provides support to the scraper assembly 700, preventing excessive stress on the lead screw 600. Furthermore, it guides the sliding of the scraper assembly 700, improving its cleaning efficiency for the roller surface adhesive.

[0040] In some possible implementations, the two ends of the slide bar 800 are snap-fitted or welded to the connector 310. Because the battery processing equipment has the aforementioned hot composite roller cleaning device, it can reduce indentations on the electrodes and separators, improve the yield of the cell pack, and achieve cost savings.
