[0002] In the process of power battery manufacturing, pole piece die-cutting is a very important process. Since die-cutting will produce waste edges, special waste collection equipment is required. The blockage of waste pipelines has always been a problem in the industry.

[0003] The existing crusher pipeline uses a dust collector or a built-in fan as the power source, and adjusts the pipeline air volume through fan frequency conversion, but the air volume cannot be adjusted locally, resulting in excessive or insufficient air volume. Excessive air volume will cause the wind speed at the die-cutting position to be too high, causing the electrode to shake, resulting in laser defocus, unstable cutting and inability to cut off the electrode, causing the equipment to shut down; too little air volume will cause the waste to be carried away, easily causing the falling material to block the pipeline, causing the equipment to shut down. Utility Model Content

[0004] The present application provides a duct air supply structure, a crushed material collection device and a die-cutting machine, which are used to solve the problem in the prior art that too much air volume in the crusher duct will lead to too high wind speed at the die-cutting position, and too little air volume will cause falling materials to block the duct.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] The following combination Figures 1-4 , describing the pipeline air supply structure provided in the embodiments of the present application.

[0036] Reference Figure 1As shown, in the embodiments provided in the present application, the pipeline air supply structure includes a conveying pipeline 100, which has an inlet 130, an outlet 140, and an air supply port 150. The air supply port 150 is connected to an air supply device so that the air supply device blows air toward the outlet 140 along a preset direction. In some specific embodiments, the inlet 130 is the head end of the conveying pipeline 100, the outlet 140 is the tail end of the conveying pipeline 100, and the air supply port 150 is opened on the side wall of the conveying pipeline 100. The preset direction is a direction at an acute angle to the conveying direction of the conveying pipeline 100. After the air supply device (such as a fan) is connected to the air supply port 150, it blows air toward the outlet 140 along a direction at an acute angle to the conveying direction of the conveying pipeline 100, thereby effectively preventing the electrode cutting debris from clogging the pipeline and maintaining the wind speed at the inlet 130 within a stable range. In some specific embodiments, the conveying pipeline 100 includes a first pipeline 110 and a second pipeline 120. The first end of the first pipeline 110 serves as a feed port 130; the first end of the second pipeline 120 serves as an air supply port 150, and the tail end of the second pipeline 120 serves as a discharge port 140. A connecting port is provided in the wall of the second pipeline 120, which communicates with the tail end of the first pipeline 110. The air supply port 150 and the discharge port 140 are positioned opposite each other at opposite ends of the second pipeline 120, thereby increasing the air velocity in the second pipeline 120 and accelerating the movement of electrode chip scraps within the second pipeline 120, thereby effectively preventing the pipeline from being clogged by electrode chip scraps. In some specific embodiments, the first pipeline 110 includes a feed section 111 and a guide section 112. The first end of the feed section 111 serves as the feed port 130; the first end of the guide section 112 communicates with the tail end of the feed section 111, and the angle between the conveying direction of the guide section 112 and the axial direction of the second pipeline 120 is acute. In this way, in the process of blowing air from the feed port 130 to the discharge port 140 , the scraps in the guide section 112 can be taken out, thereby increasing the speed at which the electrode scraps move in the guide section 112 .

[0037] By utilizing the technical solution in the above embodiment, a feed port 130, a discharge port 140 and an air supply port 150 are set on the conveying pipe 100, and the air supply port 150 is connected to the air supply equipment so that the air supply equipment blows air toward the discharge port 140 in a preset direction, so that the conveying pipe 100 from the air supply port 150 to the discharge port 140 has a higher wind speed, effectively preventing the electrode cutting debris from clogging the pipe; at the same time, the wind speed at the feed port 130 can be indirectly adjusted so that the wind speed at the feed port 130 is stably maintained within an appropriate range, thereby avoiding the phenomenon of electrode jitter and laser defocusing caused by excessive wind speed at the die-cutting position due to excessive air volume, thereby achieving stable cutting of the electrode at the die-cutting position.

[0038] Reference Figure 2As shown, in some embodiments provided herein, the duct air supply structure further includes an air volume adjustment assembly 200. The air volume adjustment assembly 200 is disposed at a position on the conveying duct 100 corresponding to the air supply port 150. The air volume adjustment assembly 200 adjusts the effective air supply area of ​​the air supply port 150 by rotating about its own axis. Thus, by disposing the air volume adjustment assembly 200 at the air supply port 150, the air supply volume at the air supply port 150 can be adjusted. The air volume adjustment assembly 200 can be appropriately rotated according to the actual material debris situation in the duct, thereby achieving flexible adjustment of the air volume and wind speed of the conveying duct 100. In some specific embodiments, the air volume adjustment component 200 includes a fixed plate 210, a central axis 220 and a rotating plate 230. The fixed plate 210 is installed on the inner wall of the conveying duct 100 at a position corresponding to the air supply port 150; the central axis 220 is arranged on the fixed plate 210; the rotating plate 230 is sleeved on the central axis 220. The area of ​​the air supply port 150 that is not blocked by the fixed plate 210 and the rotating plate 230 is the effective air supply area. The rotating plate 230 rotates around the central axis 220 so that part of the rotating plate 230 overlaps with the fixed plate 210, thereby adjusting the effective air supply area. Specifically, the larger the overlapping area of ​​the rotating plate 230 and the fixed plate 210, the larger the effective air supply area. In this way, the air volume and wind speed of the conveying duct 100 can be flexibly adjusted. In some specific embodiments, the fixed plate 210 and the rotating plate 230 are respectively fan-shaped structures. For example, referring to Figure 2 As shown, the central angles of each fixed plate 210 and rotating plate 230 are 90°, and the two fixed plates 210 are arranged opposite to each other, and the two rotating plates 230 are arranged opposite to each other, so that the fixed plates 210 and the rotating plates 230 are spaced apart to form a complete circle. When the rotating plate 230 rotates to completely not overlap with the fixed plate 210, the effective air supply area at this time is the smallest, that is, zero; when the rotating plate 230 rotates to completely overlap with the fixed plate 210, the effective air supply area at this time is the largest, which is half of the cross-sectional area of ​​the conveying duct 100. Figure 3 、 Figure 4 As shown, in other embodiments, the central angle corresponding to the fixed piece 210 can also be 60°, 45°, etc., and correspondingly, the central angle corresponding to the rotating piece 230 can also be 120°, 135°, etc. In some specific embodiments, an arc track is provided on the side of the fixed piece 210 and the rotating piece 230 that are close to each other. The arc track is a section of an arc with the central axis 220 as the center. The fixed piece 210 and the rotating piece 230 are slidably connected via the arc track. The rotating piece 230 can slide along the arc track on the surface of the fixed piece 210 to adjust the position of the rotating piece 230, thereby adjusting the effective air supply area.

[0039] Reference Figure 3 、 Figure 4As shown, in some specific embodiments, the rotating piece 230 includes at least one sub-piece 231, each sub-piece 231 having a fan-shaped structure, and the central angle corresponding to each sub-piece 231 is equal to the central angle corresponding to the fixed piece 210. For example, the rotating piece 230 includes three sub-pieces 231, the central angle corresponding to each sub-piece 231 is 60°, and the central angle corresponding to the fixed piece 210 is also 60°. Adjacent sub-pieces 231 are connected by a sliding arc track, and each sub-piece 231 can slide along the arc track on the surface of the adjacent sub-piece 231; at the same time, the sub-piece 231 close to the fixed piece 210 is also connected by a sliding arc track to the fixed piece 210, and the sub-piece 231 close to the fixed piece 210 can slide along the arc track on the surface of the fixed piece 210, thereby adjusting the effective air supply area. In other specific embodiments, the central angle corresponding to each sub-piece 231 can also be 45°, and the central angle corresponding to the fixed piece 210 can also be 45°. In this way, by overlapping the sub-pieces 231 with each other and then with the fixed piece 210, the maximum effective air supply area corresponding to the rotating piece 230 can be increased. Specifically, when the central angle corresponding to the rotating piece 230 is 90°, the maximum air supply area of ​​the air supply port 150 can reach 50% of the cross-sectional area of ​​the conveying duct 100. Similarly, when the central angle corresponding to the rotating piece 230 is 120°, the maximum effective air supply area of ​​the air supply port 150 can reach 67% of the cross-sectional area of ​​the conveying duct 100. When the central angle corresponding to the rotating piece 230 is 135°, the maximum effective air supply area of ​​the air supply port 150 can reach 75% of the cross-sectional area of ​​the conveying duct 100.

[0040] Reference Figure 2 As shown, in some embodiments provided in the present application, a rotation scale 240 is provided on the rotating piece 230. By providing the rotation scale 240, the rotation angle of the rotating piece 230 can be visualized, which is conducive to more accurate adjustment of the effective air supply area.

[0041] An embodiment of the present application also provides a debris collection device, including the pipeline air supply structure in the above embodiment.

[0042] It should be noted that the debris collection equipment includes a pipeline air supply structure, which also includes all the advantages of the pipeline air supply structure mentioned above, which will not be repeated here.

[0043] Reference Figure 5As shown, a die-cutting machine is also provided in an embodiment of the present application, including the debris collection device in the above embodiment. Specifically, the die-cutting machine also includes a vacuum conveyor belt 310, a roller 320, and a laser emitter head 330, wherein the laser emitter head 330 is located in the cutting chamber, and the electrode 400 is transported from the roller 320 to the cutting chamber, and the electrode is die-cut by the laser emitter head 330. After the die-cutting, the electrode 400 is adsorbed by the vacuum conveyor belt 310 and transported to the next workstation. The debris generated during the die-cutting process is blown into the conveying pipe 100 by the wind knife 340, and enters the subsequent debris collection equipment through the conveying pipe 100. When there are a lot of debris, the rotating piece 230 is rotated to a suitable position to increase the effective air supply area; when there are less debris, the rotating piece 230 is rotated to a suitable angle to reduce the air supply area, thereby avoiding the blockage of debris in the conveying pipe 100 while keeping the wind speed at the feed port 130 stable within a suitable range, thereby avoiding the phenomenon of electrode jitter and laser defocusing caused by excessive wind speed at the die-cutting position due to excessive air volume, so that the electrode can be stably cut at the die-cutting position.

[0044] It should be noted that the die-cutting machine includes a debris collection device, which also includes all the advantages of the debris collection device mentioned above, which will not be repeated here.
