AI Technical Summary
In the existing technology, due to the deviation of the shoe upper being fitted onto the last and the clamping error of the last, deviations occur when using a fixed teaching trajectory method during roughing, glue spraying, and treatment application, affecting the consistency of the adhesion between the shoe upper and the sole and the quality of shoe manufacturing.
By acquiring the shoe template and real-time 3D model of the shoe, the overall offset is calculated and overall correction is performed. Combined with local correction, the shoe surface processing trajectory is optimized. Point cloud data is acquired by scanning with a 3D camera, and correction is performed using rotation and translation matrices. Spherical expansion is used for local adjustment.
It improves the precision of roughing, spraying glue and applying treatment agents, enhances shoe manufacturing quality, ensures consistent adhesion between the upper and sole, and reduces glue overflow or insufficient glue.
