Chinese patent document CN218079089U discloses an automatic part weighing and sorting device, which calculates the total weight of a certain number of parts by using a gravity sensor and a weighing platform, and outputs the parts reaching the preset weight from the weighing platform through a turning plate. Although the automatic sorting device can realize automatic weighing and output of the parts, the continuity of the parts input into the sorting device before weighing is extremely poor, and the automatic conveying, weighing and output requirements cannot be met. Meanwhile, although the parts reaching the preset weight are output through the turning plate, the input of the parts has errors in quantity during weighing, so that the weighing accuracy is poor.
Chinese patent document CN217675001U discloses a vibration plate conveying device, which is to automatically convey parts along a conveying track and a direct vibration track through the cooperation of a vibration plate and a direct vibration base.
