Three-dimensional measuring system for bonding the sole and upper surface and three-dimensional measuring method thereof

The invention relates to the rubber cooperation of the sole and the upper, in particular to a measuring system for measuring the three-dimensional structure of the inner surface of the sole to obtain the bonding line of the sole and the lasted upper and the measuring method thereof.

The sneaker structure mainly includes an upper for receiving the protection of the sole of the foot, and a sole provided on the lower surface of the upper. The sole of the sneaker has a complicated shape due to its shape, so that the inner contour of the sole for bonding with the lower surface of the lasted upper is varied, and the area around the inner contour of the sole is not easy to be coated. Glue or treatment agent and low stability after gluing with the upper. Therefore, how to make the inner contour of the sole and the circumference of the upper are stably combined is the primary task when bonding the sole and the upper.

In order to improve the above problems, it has been proposed to rough-process the lower surface of the upper and the inner surface of the sole before the sole and the upper of the upper, and then apply the adhesive to the lower surface of the upper and the inner surface of the sole. Increase the roughness between the upper and the sole to achieve enhanced bonding strength. However, when roughing or adhesive coating is insufficient, the upper and the sole are still easily separated in a short time. In the case of an opening. In addition, the rough surface and the periphery of the lower surface of the upper surface of the veneer are also easy to expose the rough surface of the processing or the glue overflows to the visible range, thereby reducing the quality of the sports shoes.

Therefore, it is currently only possible to manually perform the bonding of the sole and the upper. The bonding method is a shoemaker's production line on the upper, by combining a sole having a desired shape and size as a pattern and an upper, and manually drawing the edge line of the sole on the periphery of the lower surface of the upper as The marking of the upper processing range.
