Abstract

The invention provides a movement trajectory planning method and device, a pocket patching machine and a storage medium. An ISO file including a sewing trajectory of a material to be sewed is obtained, coordinate information is extracted according to the ISO file and then is segmented according to the coordinate information, the coordinate information is dispersed according to the information suchas an upper needle position and a lower needle position so as to obtain discrete coordinate information, respectively corresponding to a machine needle, a rotating shuttle, an X axis and a Y axis, ofthe coordinate information, finally a quintic spline curve algorithm is utilized to conduct certain times of interpolation processing on the discrete coordinate information of the X axis and the Y axis, and smooth movement trajectories corresponding to the X axis and the Y axis are respectively obtained. By adopting the movement trajectory planning method, the positioning precision can be improved, speed and acceleration curves of the motor movement trajectories are smoother, sewing stitches are more uniform, and a sewing process effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewing equipment numerical control. In particular, it relates to a motion trajectory planning method and its device, a bag pasting machine and a storage medium. Background technique [0002] The automatic pocket patching machine is mainly used in the sewing equipment of jeans and shirt pockets. The traditional sewing machine realizes the automatic cloth feeding function by the cloth feeding dog. The automatic pocket patching machine uses two linear modules of X and Y to realize the cloth feeding and sewing. During the process, the X and Y cloth feeding motors need to be frequently started and stopped. Therefore, the planning of the motion track is particularly important. If the planning is not good, the motor will vibrate, the equipment will vibrate, the fabric will be scratched and the needle will be damaged, and the service life of the motor will be reduced. And if the planning is good, the equipment ...
