AOI shooting mechanism

Abstract

The invention discloses an AOI shooting mechanism. The shooting mechanism comprises a shell with an open upper end, wherein fixing supports are arranged at the left and right sides of the shell, a moving frame is arranged above the shell, guide rails are arranged on the front and rear wall surfaces of the shell, the moving frame is movably connected with the interiors of the guide rails in an inserted mode, an installation base is hinged to the moving frame through a hinge shaft, a camera is installed on the installation base, a rotating device used for driving the hinge shaft to rotate is arranged on the moving frame, a moving assembly used for driving the moving frame to move along the guide rails is arranged on the shell, and a cleaning assembly used for cleaning the camera is arrangedin the shell. When the camera needs to be cleaned, the camera is driven by the rotating device to rotate, so that the camera faces downwards, then the camera is cleaned by the cleaning assembly, the cleaning efficiency is high, and a cleaning effect is good, so that the use requirements are met.

Description

technical field [0001] The invention relates to an AOI camera mechanism. Background technique [0002] The full name of AOI 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. However, in actual use, due to the long-term use of the machine, it is inevitable that dust will accumulate. Especially for machines that detect double-sided panels, since cameras are installed on the upper and lower sides, ...

Problems solved by technology

However, in actual use, due to the long-term use of the machine, it is inevitable that dust will accumulate. Especially for machines that detect double-sided panels, since cameras are installed on the upper and lower sides, the lower camera needs to face upward for image acquisition, so dust will accumulate. On the lens, the accumulation of dust will affect the image acquisition, which will lead to misjudgment in the later image recognition process, which will affect the detection efficiency. Therefore, there is an urgent need for an AOI camera mechanism that can be automatically cleaned to solve this problem.
