Abstract

The invention provides an automatic cutting bed cutter deformation detection device. According to the device, the cutter deformation caused by cutting cloth in the rotation process of the cutter is detected in real time through a displacement sensor, and the detected analog voltage signal is subjected to digital transformation. Under the control of a program in a micro controller, firstly the cutter deformation is analyzed and judged, then a servo motor is controlled and the cutter is driven to carry out rotation compensation to the opposite direction of deformation, and the automatic correction of the cutter cutting direction is realized. The fact that the cutting error caused by the cutter deformation is always controlled in an allowable range is ensured, and the cutting quality and precision are raised.

Description

technical field [0001] The invention relates to a detection device for detecting the deformation of an automatic cutting bed cutting knife. Background technique [0002] Automatic cutting bed is a high-end product among garment CAM equipment. It uses digital information such as style design, pattern design, grading, and nesting in the garment CAD system to control the automatic production and manufacturing system to realize automatic cutting of multi-layer garments. At present, automatic cutting machines are mainly produced in Europe, America and other countries. Foreign companies have mastered the core technology, and the equipment prices are generally relatively high. The parts and maintenance costs are high, and the equipment often cannot be repaired in time. [0003] A device capable of detecting and automatically correcting the deformation of the cutting knife of an automatic cutting machine is needed. Contents of the invention [0004] The main purpose of the presen...
