Abstract

The embodiment of the invention discloses a tread defect detection method and system. The tread defect detection method comprises the following steps of: photographing a laser image of a tread by utilizing a three-dimensional camera; and judging whether a connector and a central line of the tread have defects or not by a controller according to laser height information in the laser image. The laser image photographed by the three-dimensional camera is provided for the controller; in a rotating process of a belt ply drum, the laser height information in the laser image is analyzed by the controller, and whether the connector and the central line of the tread have the defects or not according to the laser height information; if the connector or the central line has the defects, an alarming device is controlled to output an alarming signal; and then the tread is adjusted by a worker. If the connector and the central line have no defects, a signal is transmitted to a molding drum by a transferring ring and the next step of operation is carried out. By adopting the tread defect detection method disclosed by the invention, whether the tread has the defects or not does not need to be manually detected, so that the defect detection speed is increased, and furthermore, the production efficiency of tires is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a tread defect detection method and system. Background technique [0002] The tread of the tire is the rubber layer of the outermost layer of the raw tire. The tread is pasted on the belt drum after the belt is pasted. First, the tread head is pasted on the belt. At the center line of the belt drum, the belt drum rotates once, and the tire fabric end is attached to the joint of the material head; then, the tread joint is rolled by the pressure roller device to make the material end and the material end bonded together. Finally, judge the fitting degree of the joint. After meeting the standard, it will be transferred to the forming drum by the transfer ring. If it does not meet the standard, human intervention and adjustment are required. [0003] In the prior art, after the tread bonding is completed, on-site staff judge whether the bonding of the tread joint is qualif...
