Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

Example (b): as shown in fig. 1 to 3, a splitting machine with a burr full-detection device comprises an unwinding device 1 for placing a pole piece 8, a deviation rectifying system 2 for preventing the pole piece 8 from being skewed, a splitting device 3 for splitting the pole piece 8, a width detection line camera 4 for detecting the width of the split pole piece 8 and a winding device for winding the split pole piece 8, wherein the pole piece 8 passes through the unwinding device 1, the deviation rectifying system 2, the splitting device 3, the width detection line camera 4 and the winding device, the unwinding device 1, the deviation rectifying system 2, the splitting device 3, the width detection line camera 4 and the winding device are arranged in sequence, the pole piece 8 is in a high-speed production state of the splitting device 3, the existing width detection line camera 4 can only shoot a split edge of one section of the pole piece 8 at a shooting frequency, the pole piece cannot be shot continuously without interruption, and the burr 9 full detection of the edge of the pole piece 8 cannot be realized, resulting in a high scrap rate of the pole piece 8.

In order to reduce the probability of burr 9 on the pole piece 8, further reduce the rejection rate of the pole piece 8 and prevent defective products from flowing into the next process, a full cut edge burr inspection device is installed between the width detection linear array camera 4 and the winding device, the full cut edge burr inspection device comprises a high-precision dynamic camera 7, the model of the camera is MV-CH1510-10XM, and the lens of the high-precision dynamic camera 7 and the section of the cut pole piece 8 are arranged in parallel and the high-precision dynamic cameras 7 are multiple.
