Description

Conveying device and method for sheet metal part production based on industrial vision Technical Field The invention relates to the technical field of conveying equipment, in particular to a conveying device and a conveying method for sheet metal part production based on industrial vision. Background In sheet metal part production and processing field, the sheet metal part conveying device commonly used in factories is composed of a conveying table, a conveyor and a conveying roller, and the core is used for realizing continuous conveying and preliminary positioning of sheet metal parts. Such devices typically have an industrial vision camera disposed in the middle of the conveying path, the camera being mounted by a fixed bracket, and performing surface imaging on the sheet metal part conveyed to a designated position by means of vertical irradiation. The detection principle is that defects such as bulges, scratches and depressions on the surface of the sheet metal part are identified by means of a visual analysis technology, and the conveying flow is approximately that the sheet metal part is conveyed to a detection area through the cooperation of a conveyor and a conveying roller, the sheet metal part is positioned by suspending operation of the device, and after the vertical detection of a camera is completed, the sheet metal part is conveyed to the next procedure by restarting the device, and the whole flow takes continuous conveying and basic surface detection as cores, so that the basic requirement of conventional production is met. The existing sheet metal part conveying device has a plurality of functional limitations in actual production, and the actual requirements of fine production of sheet metal parts are difficult to meet. Firstly, the detection gesture is single fixed, and the industrial vision camera adopts fixed perpendicular irradiation mode more, only can cover sheet metal component upper surface area, can't carry out effective detection to hidden positions such as inner wall is bent to both sides, leads to the defect in this kind of region to be ignored always, forms the detection blind area, directly influences product detection qualification rate. Secondly, lack with detect link linked automatic sorting mechanism, detect unqualified sheet metal component after, need rely on the manual work to carry out screening separation, drag slow production beat, still easily because of the problem of defective products and qualified product compounding that human misoperation appears, bring the hidden danger for follow-up process quality control.
