Naked guide rail of automatic optic inspection device

Abstract

The invention provides a naked guide rail of an automatic optic inspection device. The naked guide rail comprises a plurality of guide rail modules which are arranged in sequence; each guide rail module comprises a guide rail mounting frame, a guide rail driving motor, a power assembly, a protection plate structure and a limiting mechanism, wherein the guide rail driving motor is connected onto the guide rail mounting frame; the power assembly is arranged on the guide rail mounting frame in a penetrating manner and the guide rail driving motor is connected with the power assembly through a driving belt; the protection plate structure and the guide rail mounting frame are arranged at interval; the bottom of the power assembly is arranged in the protection plate structure; the limiting mechanism is arranged on the guide rail mounting frame; the limiting mechanism is located between the adjacent guide rail modules. The naked guide rail of the automatic optic inspection device has the following beneficial effects that the structure sis simple and the cost is low; the friction force between a conveying ring and a PCB (Printed Circuit Board) can be increased through conveying teeth on atop surface of the conveying ring and power can be more effectively transmitted to the PCB, so as to drive the PCB to move frontward; a circular-platform-shaped adjusting column can be adaptive to thePCBs with different sizes, so that whole equipment can be adjusteding in a certain range.

Description

technical field [0001] The invention relates to an automatic optical detection device, in particular to a bare board guide rail of the automatic optical detection device. Background technique [0002] The full name of AOI (Automatic Optic Inspection) is automatic optical inspection, which is a device based on optical principles to detect common defects encountered in welding production. AOI is a new type of testing technology emerging, but it is developing rapidly, and many manufacturers have launched AOI testing equipment. During automatic detection, the machine automatically scans the PCB through the camera, collects images, compares the tested solder joints with the qualified parameters in the database, and after image processing, checks out the defects on the PCB, and displays / labels the defects through the display or automatic signs out for repair by the maintenance crew. [0003] Using high-speed and high-precision visual processing technology to automatically detect...
