Embodiment Construction

[0024] As shown in Figure 1 and Figure 2, the present invention fixes the shoe last 1 on the experimental platform, the camera 4 and the line laser 2 are installed on the mobile platform 3, there is no relative movement between the camera 4 and the line laser 2, and the motor 5 drives The movement of the mobile platform 3 drives the line laser 2 to continuously scan the bottom surface of the shoe upper on the shoe last 1. The camera 4 collects images and connects them to the PC through the image acquisition card. The PC controls the motor 5 through the motion control card.

[0025] The image acquisition card is PXC-200L series or similar products.

[0026] The motion control card mentioned is GT-400-SG series and similar products.

[0027] As shown in Fig. 1, the present invention includes two parts: a hardware part and a software part. The hardware part mainly includes image acquisition card, camera, motion control card, motor, line laser and computer; the software part incl...

Abstract

The present invention discloses a method and system for generating sole glue-spraying track automatically based on linear structure light sensor. Obtaining upper underside three-dimensional coordinates data using linear laser, vidicon, mobile platform and computer, and generating glue-spraying track automatically. The linear laser scans upper underside continuously, and the vidicon collects laser scanning image at the same time, then distilling laser beam center in the image and transforming to three-dimensional coordinates through image processing, thus obtaining point-cloud data of upper underside, generating glue-spraying track according to the point-cloud data. Compared with the method by machine, the generating method of the present invention has the advantage of high orientation precision, simple operation method, strong adaptability, high efficiency etc., and has great superiority.

Description

technical field [0001] The invention relates to a method for generating a glue-spraying trajectory for shoe soles, in particular to a method and system for generating a glue-spraying trajectory based on line-structured light scanning of the bottom surface of a shoe upper. Background technique [0002] The sole glue spraying process is a key process of machine-made shoes, which determines the quality of shoes to a certain extent. The traditional shoe sole glue spraying process generally adopts manual or manual semi-automatic operation, the production efficiency is low, the glue spraying performance cannot be effectively guaranteed, and the toxic gas volatilized from the glue seriously threatens the health of the operators. [0003] The key to realizing the automation of the sole glue spraying process lies in the automatic generation of the glue spraying track. Most of the existing trajectory generation methods use the method of machine teaching, which has low efficiency, dif...
