[0042] As Figures 1-3As shown, the heat laminating roller cleaning device mainly comprises a body 100. The body 100 is configured to be arranged at one side of the heat laminating roller 200. Specifically, the body 100 comprises a first arc surface 110 and a second arc surface 120, both of which are arranged towards the heat laminating roller 200, the first arc surface 110 is provided with a first air suction port 130 and a first air blowing port 150, the second arc surface 120 is provided with a second air suction port 140 and a second air blowing port 160, and the distance between the first air blowing port 150 and the second air blowing port 160 is smaller than the distance between the first air suction port 130 and the second air suction port 140; the first air blowing port 150 and the second air blowing port 160 are both used for blowing the adhered objects on the heat laminating roller 200, and the first air suction port 130 and the second air suction port 140 are both used for sucking the adhered objects.

[0043] Based on the above design, the first air blowing port 150 and the second air blowing port 160 are used for blowing the adhered objects on the heat laminating roller 200, so that the adhered objects can be blown away from the heat laminating roller 200. The first air suction port 130 and the second air suction port 140 are both used for sucking the adhered objects blown away from the heat laminating roller 200, so that the adhered objects can be sucked away. In the embodiment, the distance between the first air blowing port 150 and the second air blowing port 160 is smaller than the distance between the first air suction port 130 and the second air suction port 140, in other words, the first air blowing port 150 and the second air blowing port 160 are both located at the middle position of the body 100, and the first air suction port 130 and the second air suction port 140 are both located at the edge position of the body 100, so that when the first air blowing port 150 and the second air blowing port 160 blow air, a negative pressure area can be formed at both sides of the first air blowing port 150 and the second air blowing port 160 (i.e. the positions of the first air suction port 130 and the second air suction port 140), so that the adhered objects can be sucked away, thereby ensuring the cleanliness of the roller surface of the heat laminating roller 200, avoiding the phenomenon that the pressure marks appear on the pole piece and the diaphragm when the heat laminating roller 200 is used to roll the pole piece and the diaphragm, improving the product yield of the core package, and achieving the purpose of saving cost.

[0044] Preferably, the body 100 in the embodiment is arranged above the heat laminating roller 200, so that the heat laminating roller 200 can support the body 100 to a certain extent, reducing the connecting components between the heat laminating roller 200 and the body 100, simplifying the structure, and facilitating the later disassembly and maintenance.

[0045] Optionally, the first air blowing port 150 and the second air blowing port 160 in the embodiment can both be provided in multiple numbers, and the first air suction port 130 and the second air suction port 140 can both be provided in multiple numbers.

In this way, the distances between the plurality of first air outlets 150, the plurality of second air outlets 160 and the roller surface can be kept as consistent as possible, so as to ensure that the air flows blown out by the plurality of first air outlets 150 and the plurality of second air outlets 160 have equivalent forces acting on the adhesive cover, and the cleaning efficiency on the adhesive cover is ensured.

[0048] Optionally, in the embodiment, the first air outlet 150 and the second air outlet 160 are both circular holes or both strip-shaped holes; and the first air inlet 130 and the second air inlet 140 are both circular holes or both strip-shaped holes. Preferably, the first air outlet 150 and the second air outlet 160 are both circular holes, the first air inlet 130 and the second air inlet 140 are both strip-shaped holes, and the area of each circular hole is smaller than the area of each strip-shaped hole. In this way, the adhesive cover can be sucked away by the strip-shaped hole with a larger shape as much as possible, and the circular hole with a smaller shape is avoided from being blocked, and the cleaning efficiency on the adhesive cover is improved.

[0049] As shown in Figure 1 and Figure 3 , the body 100 in the embodiment is provided with a third air inlet 170, and the body 100 is internally provided with a cavity 180. One side of the cavity 180 is in communication with the first air inlet 130 and the second air inlet 140, and the other side of the cavity 180 is in communication with the third air inlet 170. The adhesive cover can be sucked into the cavity 180 by the first air inlet 130 and the second air inlet 140, and then moved to the third air inlet 170 by the cavity 180 and discharged to the outside of the body 100. The cavity 180 can form a certain storage space for the adhesive cover, and improve the cleaning efficiency.

[0050] Further, as shown in Figure 1 , the third air inlet 170 in the embodiment has an outer edge 1701 which is protruded from the body 100. The thermal laminating roller cleaning device further comprises an air suction assembly (not shown in the figure) and an air blowing assembly (not shown in the figure). The air suction assembly is in communication with the third air inlet 170 through the outer edge 1701, and the air blowing assembly is in communication with the first air outlet 150 and the second air outlet 160. The outer edge 1701 can improve the stability and reliability of the connection between the third air inlet 170 and the air suction assembly, reduce the loosening phenomenon between the two, and improve the installation efficiency.

[0051] Exemplarily, the air suction assembly in the embodiment can be configured as a negative pressure pump, and the air blowing assembly can be configured as a positive pressure pump. Of course, the operator can also select other devices capable of air blowing and air suction, which will not be described one by one here.

[0052] As shown in Figures 4-5 The embodiment also provides a battery processing equipment, which comprises a thermal compounding roller 200, a mounting seat 300, a first driving assembly 400 and the above-mentioned thermal compounding roller cleaning device. The thermal compounding roller 200 is installed in the mounting seat 300, and the first driving assembly 400 is drivingly connected with the thermal compounding roller 200, so that the first driving assembly 400 drives the thermal compounding roller 200 to rotate. The thermal compounding roller cleaning device is arranged on the mounting seat 300.

[0053] Specifically, the body 100 is provided with support portions 190 on opposite sides, which are used to be lapped on the mounting seat 300 of the thermal compounding roller 200. The operation is convenient, the work efficiency is high, no fixing member such as a bolt or a screw is needed for installation, the cost is reduced, and the maintenance and replacement of the thermal compounding roller cleaning device in the later period are facilitated.

[0054] Exemplarily, the first driving assembly 400 can be configured as a motor, which drives the thermal compounding roller 200 to rotate, thereby realizing the thermal compounding process of the diaphragm and the pole piece.

[0055] Optionally, the first driving assembly 400 and the thermal compounding roller 200 in the embodiment can be configured as a plurality of ones, and the first driving assembly 400 and the thermal compounding roller 200 are arranged in one-to-one correspondence.

[0056] As shown in Figures 4-5 The battery processing equipment further comprises a second driving assembly 500, a lead screw 600, connecting members 310 and a scraper assembly 700. The connecting members 310 are arranged opposite to each other in two numbers, and both of the connecting members 310 are connected with the mounting seat 300. Both ends of the lead screw 600 are independently rotatably connected with the two connecting members 310. The second driving assembly 500 is drivingly connected with the lead screw 600 to drive the lead screw 600 to rotate, and the lead screw 600 is located directly above the thermal compounding roller 200. The scraper assembly 700 is connected with the lead screw 600. In this way, the driving of the second driving assembly 500 to the lead screw 600 enables the lead screw 600 to rotate, and the rotation of the lead screw 600 can drive the scraper assembly 700 on the lead screw 600 to move forward and backward. Specifically, the second driving assembly 500 drives the rotation of the lead screw 600 by forward rotation and reverse rotation, thereby realizing the reciprocating motion of the scraper assembly 700, so as to increase the cleaning area of the scraper assembly 700 on the roller surface and avoid the occurrence of a cleaning dead zone.

[0057] Further, the lead screw 600 in the embodiment is rotatably connected with the connecting members 310 through bearings (not shown in the figure).

[0058] For example, the second drive component 500 can be configured as a motor, which drives the lead screw 600 to rotate forward or reverse, so as to realize the reciprocating motion of the scraper assembly 700.

[0059] It should be noted that the scraper assembly 700 in this embodiment is a conventional component in the art, therefore, its specific structure and working principle will not be described in detail in this embodiment.

[0060] like Figure 5 As shown, the battery processing equipment in this embodiment also includes a slide bar 800. Both ends of the slide bar 800 are independently connected to two connecting members 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 for the scraper assembly 700, preventing excessive force on the lead screw 600. Furthermore, it guides the sliding of the scraper assembly 700, improving its cleaning efficiency for the roller surface adhesive.

[0061] Optionally, in this embodiment, both ends of the slide bar 800 are snap-fitted to or welded to the connector 310.
