Engine cylinder cover defect automatic detection equipment based on machine vision

Abstract

The invention discloses engine cylinder cover defect automatic detection equipment, and belongs to the field of machine vision detection equipment. The equipment mainly comprises a frame, a catching device, a delivering unit, a vision imaging unit, and an electric control unit. The catching device is arranged on the front end and is used to catch an engine cylinder cover from a transportation guide rail to a transmission device platform; the transmission device platform is arranged on the frame and can stably deliver the cylinder cover in a uniform speed; the vision imaging device is arranged on an optical support and is used to scan the images of cylinder cover; a position sensor is arranged on two side of the whole machine and is used to detect the position of cylinder cover during the transportation process; the control part of the equipment is connected to an IPC (industrial personal computer), and all control commands are sent by the IPC. The equipment is used to recognize and sort defects on the surface of engine cylinder cover such as sand holes, pores, bonded sand, scars, concave-convex, and the like; and thus the surface defects on the surface of cylinder cover can be automatically detected to ensure the stable and reliable quality of products.

Description

technical field [0001] The invention relates to the field of machine vision detection, in particular to an automatic detection device for surface defects of an engine cylinder head based on machine vision. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, my country's automobile localization process continues to accelerate, the demand for automobile consumption is strong, and the number of automobiles maintains a rapid growth trend, making China the world's largest automobile production and sales country. The engine cylinder head casting is the core part of the automobile engine. As the core part of the automobile engine, the engine cylinder head is also one of the most complex mass-produced castings in the automobile castings. Most of the core technologies of the engine are concentrated on the cylinder head. The casting of engine block and cylinder head is the most difficult and most impor...

Problems solved by technology

[0004] The current detection method is to use manual visual detection, which is not only time-consuming and inefficient, but also has a great relationship with subjective factors such as the inspector's own technical level, naked eye resolution, experience and fatigue. The lack of accuracy and standardization of test results has become a bottleneck factor restricting production efficiency and quality
