A kind of detection method of tire label position in tire vulcanization production process

Abstract

The invention belongs to the technical field of vision detection, and particularly relates to a method for detecting a tire label position in a tire vulcanization producing process. The method comprises the steps that 1, a target is designed; 2, a label placement range template is designed; 3, the target is fixedly installed on the outer edge of a vulcanizing machine film cavity; 4, the position of the target and the position of the label placement range template are demarcated; and 5, the tire label position is detected in practical production. By means of the method, the problem that the label position is inaccurate due to the fact that the position of the vulcanizing machine film cavity is changed in a vulcanizing process is solved, the rejection rate is avoided, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of visual inspection, and in particular relates to a method for detecting the position of a tire label in the tire vulcanization production process. Background technique [0002] In the automatic loading and unloading process of the robot, the certainty of the target position determines the accuracy with which the robot can correctly place the workpiece according to the specified path. If the target position is in a random state of change, it will be more difficult for the robot to accurately place the workpiece. The accuracy of the placement of the workpiece will directly affect the normal and reliable operation of the subsequent stations. Excessive data deviation will lead to unqualified product quality. [0003] At present, most of the vulcanizing machines used in the vulcanization process of the domestic tire manufacturing industry are in the hydraulic mode. The accuracy of placing the tire label in the...

Problems solved by technology

If the target position is in a random state of change, it will be more difficult for the robot to accurately place the workpiece, and the placement accuracy of the workpiece will directly affect the normal and reliable operation of the subsequent stations. Excessive data deviation will lead to unqualified product quality

[0003] At present, most of the vulcanizing machines used in the vulcanization process of the domestic tire manufacturing industry are in the hydraulic mode. The accuracy of placing the tire label in the cavity greatly reduces the position accuracy and reliability of the vulcanized tire label on the tire, which affects the product quality of the automatic vulcanization tire system

[0004] At the same time, due to the particularity of the membrane cavity structure of the vulcanizer, the vision system can only shoot obliquely from the side and above. The change of the upper and lower positions of the membrane cavity will change the distance between the vision system and the target, resulting in a significant change in the size of the target object in the image. , it is necessary to correct the translation and rotation angle of the target, which increases the difficulty of accurate detection by the vision system
