Abstract

An automatic sweater sewing method based on machine vision perception comprises the following steps of: (1) starting automatic sweater sewing equipment; (2) conveying a sweater weaving piece into a stretching and freezing device from front to back from an input flattening device; (3) stretching the sweater weaving piece and freezing the sweater weaving piece into a rigid body convenient for sewingin the stretching and freezing device; (4) conveying the sweater weaving piece which is stretched and frozen into the rigid body to a sewing preparation device; and (5) finishing turning, carrying, sewing auxiliary pushing and sorting of the frozen sweater weaving piece by a carrying robot, and sewing an upper sweater weaving piece and lower sweater weaving piece which are correspondingly arranged up and down by using a sewing device. The method can replace prior manual sweater sewing, improves the processing efficiency, achieves the improvement of the sewing quality, achieves the stable consistency of products in batch production, and further improves the added value of the products; and the method has certain significance for promoting the development of equipment in the sweater weavingindustry in China.

Description

technical field [0001] The invention belongs to the technical field of wool weaving, and in particular relates to an automatic sewing method for sweaters based on machine vision perception. Background technique [0002] my country is a big country in the wool weaving industry, and the wool weaving process mainly includes four major processes: weaving, seaming (sewing), washing, and inspection. Among them, the weaving, washing, and inspection processes have all been automated, and only the seaming (sewing) ) also requires manual operation, so the wool weaving industry is still a labor-intensive industry. As labor costs continue to rise, companies are eager to replace people with machines and reduce product quality assurance based on personal experience. [0003] In order to realize the automatic stitching (sewing) of sweaters, the patent of the present invention transforms the flexible sweater pieces into rigid frozen sweater pieces after stretching and freezing operations, s...
