Visual inspection equipment capable of identifying flaws for large part inspection

Abstract

The invention discloses visual inspection equipment capable of identifying flaws for large part inspection. Particularly, the equipment comprises a workbench, a feeding mechanism, an oily pen and a CCD camera, a computer operation room is arranged in the middle of one end of the top of the workbench, and a frame body is arranged at the other end of the top of the workbench; a feeding conveying belt is fixed to one side of the top of the workbench through an installation frame, and a photoelectric sensor is installed on the side, close to the feeding conveying belt, of the interior of the feeding conveying belt. The visual detection equipment capable of identifying flaws for large part detection is provided with a transverse electromagnetic sliding rail, a longitudinal guide rail, a hydraulic lifting rod and the oily pen. The oil pen can move to the flaws of the part under the synergistic effect of the transverse electromagnetic sliding rail, the longitudinal guide rail and the hydraulic lifting rod to draw circles and mark the detected flaws, follow-up rework of workers is facilitated, and the rework efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a visual inspection device capable of marking defects for inspection of large parts. Background technique [0002] Visual inspection is to use machines instead of human eyes for measurement and judgment. In some dangerous working environments that are not suitable for manual work or where artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; at the same time, in mass industrial production processes Among them, using artificial vision to check product quality is low in efficiency and accuracy, and machine vision inspection methods can greatly improve production efficiency and production automation. The wider the application. [0003] At present, some large-scale factories use visual inspection equipment to detect parts. For large parts, generally defective products will not be discarded directly, but need to ...

[0002] Visual inspection is to use machines instead of human eyes for measurement and judgment. In some dangerous working environments that are not suitable for manual work or where artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; at the same time, in mass industrial production processes Among them, using artificial vision to check product quality is low in efficiency and accuracy, and machine vision inspection methods can greatly improve production efficiency and production automation. more widely used

[0003] At present, some large-scale factories use visual inspection equipment to detect parts. For large parts, generally defective products will not be discarded directly, but need to be reworked. The alarm reminds employees to take away the defective product, but it cannot mark the defective part at the same time as the detection. Since the defect of each part may be different, employees often only know that the part has a defect when reworking later, but they cannot immediately know the defect. The specific location and quantity, so it needs to be manually checked again before rework can be reworked, the accuracy is poor, and the probability of missed detection and false detection is also high
