Then, the first cylinder 425 retracts the flipping track 424, and the flipping motor 422 drives the flipping track 424 to flip, causing the product to flip 180 degrees. The second cylinder 428 drives the second cutting block 429 to move, thereby breaking off the excess terminal strip on the product. The broken part falls into the waste bin. The flipping motor 422 drives the flipping track 424 to flip again, and the first cylinder 425 pushes the flipping track 424 into the processing track 2 to complete the material breaking operation.
