一种极片放卷料筒工装

Abstract

本实用新型涉及锂电池生产技术领域，具体为一种极片放卷料筒工装，包括放卷料筒本体，所述放卷料筒本体用于收放卷极片，所述放卷料筒本体上表面开设有相近的第一开口和第二开口，所述放卷料筒本体表面下面开有缓存腔体，所述第二开口位置内部两端设置有转动轴，所述转动轴的表面固定连接有尾料接引带。本实用新型，降低了因放卷卷径检测不准造成极片“飞带”的现象，进而减小了设备的故障率；本实用新型采用带极片尾料接引带的料筒，降低了因卷径检测误差过大造成极片尾料报废量过多的问题，降低了极片的报废率，同时提升了材料的利用率；本实用新型极片放卷料筒工装，尾料接引带可回收重复利用，降低了整体的生产采购成本。

Claims

1. A tooling for an electrode unwinding drum, comprising an unwinding drum body (1), characterized in that: The unwinding drum body (1) is used to unwind and wind up the electrode sheets. The upper surface of the unwinding drum body (1) is provided with a first opening (11) and a second opening (14) that are close to each other. A buffer cavity (12) is provided on the lower surface of the unwinding drum body (1). Rotating shafts (13) are provided at both ends inside the second opening (14). A tail material guide belt (3) is fixedly connected to the surface of the rotating shaft (13). The tail material guide belt (3) passes through the buffer cavity (12) and emerges from the first opening (11). The tail material section of the tail material guide belt (3) that emerges from the first opening (11) is connected to the electrode sheet roll (2). The unwinding drum body (1) winds and winds up the electrode sheet roll (2) and the surface of the unwinding drum body (1).

2. The pole piece unwinding material canister tool of claim 1, wherein: After the unwinding cylinder body (1) finishes winding the electrode roll (2), it is fixedly wound onto the air expansion shaft on the equipment. The buffer cavity (12) is opened at a distance of 5-10mm below the surface of the unwinding cylinder body (1).

3. The pole piece unwinding material canister tool of claim 2, wherein: The thickness of the buffer cavity (12) is 10-15 mm, and the longitudinal depth of the first opening (11) and the second opening (14) is equal to the thickness of the buffer cavity (12).

4. The pole piece unwinding material canister tool of claim 1, wherein: The first opening (11) and the second opening (14) are connected to each other through the buffer cavity (12). The width of the first opening (11) and the second opening (14) is greater than the width of the tail material receiving belt (3).

5. The pole piece unwinding material canister tool of claim 1, wherein: The rotating shaft (13) passes through the interior of the second opening (14), and bearings (15) are installed at both ends of the rotating shaft (13). The bearings (15) are fixed on both sides of the unwinding cylinder body (1).

6. The pole piece unwinding material canister tool of claim 4, wherein: One end of the tail material connecting strip (3) is connected to the rotating shaft (13), and its length is 500-1000mm. The width of the tail material connecting strip (3) depends on the width of the electrode sheet.

7. The pole piece unwinding material canister tool of claim 6, wherein: After the unwinding drum body (1) tooling is replaced, the tail material receiving belt (3) is rotated by the rotating shaft (13) and recycled to the buffer cavity (12).
