This utility model provides a hinge and a refrigerator including the same. The hinge includes: a first fixed base; a second fixed base; a transmission assembly; and a buffer assembly, which is mounted on the first fixed base or the second connecting member and extends toward the fifth connecting member. A buffer mating part is provided on the side of the fifth connecting member facing the buffer assembly. The buffer assembly is configured to switch from a non-active state to an active state when the buffer mating part abuts against the buffer end face of the buffer assembly during the closing process of the door. The fifth connecting member is the rod used to cooperate with the buffer assembly to achieve the buffering effect. During opening and closing, the fifth connecting member bears a smaller weight of the door, which helps to ensure the overall strength of the hinge. Mounting the buffer assembly on the first fixed base or the second connecting member increases the buffer stroke of the buffer assembly, enabling it to maintain a better buffering effect even when the door speed changes abruptly, thereby reducing or preventing damage to the refrigerator door and cabinet.

The application provides a method and system for segmenting FMM plates. The method comprises identifying whether the segmentation strip on the FMM plate after the first etching and before the etching back protection film is removed is an etching residual segmentation strip, determining the etching parameters corresponding to the secondary etching according to the gray scale image of the etching residual segmentation strip; based on the coordinate range of each etching residual segmentation strip and the etching parameters corresponding thereto, combining the contour image of the etching front surface non-etching area (product unit area) of the FMM plate to control the precise spraying mechanism and etching nozzle to perform secondary etching on all etching residual segmentation strips. The technical solution provided by the application accurately identifies the etching residual segmentation strips on the FMM with the aid of image recognition technology, accurately controls the spraying mechanism and etching nozzle to perform secondary etching on the etching residual segmentation strips, ensures that the product unit will not be damaged when the protection film is removed, and improves the yield of FMM products.
