Identifying and trimming device for two-dimensional irregular outer shape of soft material

Abstract

The invention discloses an identifying and trimming device for the two-dimensional irregular outer shape of a soft material. According to the device, the trimmed material can be flattened on a machineconveying belt, the shape contour and the surface condition of the trimmed material are subjected to two-dimensional visual identification, the material appearance is automatically trimmed by a waterjet scalpel, and the trimmed material is automatically returned to the position near the feeding position; and a machine is configured with an independently developed special-purpose program for control to replace human eyes and human hands, and all the processes of acquiring edge information such as the shape, holes and surface scars, calculating a cutting path, conducting visual identification,determining a trimming track, conducting trimming machining and returning to a feeding position are automatically completed. Moreover, in the same time period during which the previous piece of material is machined, the visual identification and processing track online calculation of a last piece of material are conducted in parallel, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of outer edge trimming of soft materials, and in particular relates to a device for identifying and trimming two-dimensional irregular shapes of soft materials. Background technique [0002] The invention relates to trimming the outer edge of soft materials with irregular shapes by using water jets, especially for the automatic recognition and trimming of the leather shapes of large animals such as cattle and sheep. The applicable processing objects are so-called "soft materials", which are not strictly According to the scientific definition, the present invention defines it as: a sheet-like solid material that can deform downward due to its own gravity at a position without bottom support. It mainly refers to the types of materials such as cloth, leather, fiber, film, etc., which have a large relative ratio of area to thickness, high flexibility, and low hardness. [0003] It is often necessary to trim the...

AI Technical Summary

Problems solved by technology

For example, how to increase the cutting speed to an order of magnitude of tens of meters per minute. The general waterjet machine structure cannot meet this requirement at present; another example is the soaking of the cut material by water, and the contradiction between drainage and support, etc. Wait
