Description

Technical Field

[0001] This utility model relates to the field of visual inspection mechanisms, and in particular to an automated partial visual inspection mechanism for hot stamping sheet metal. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection refers to the process of using machine vision products (i.e., image acquisition devices, which are divided into CMOS and CCD) to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signals are converted into digital signals. The image system performs various operations on these signals to extract the features of the target, and then controls the operation of on-site equipment based on the judgment results.

[0003] In one design, the hot-pressed product is transported to the inspection position for a full inspection of the product's appearance, holes, and other features.

[0004] However, the product is relatively large in size, so how to detect the bottom is one of the key design considerations, and the lighting setup is one of the key points. Utility Model Content

[0005] The main purpose of this invention is to propose an automated partial visual inspection mechanism for hot stamping sheet metal, which aims to detect the bottom surface of the product and thus improve the detection accuracy.

[0006] To achieve the above objectives, this utility model proposes an automated partial visual inspection mechanism for hot stamping sheet metal, comprising:

[0007] A transport device for conveying products;

[0008] The carrier includes a crossbar and a vertical bar extending from the crossbar toward the transport device.

[0009] The upper wall of the carrier is provided with a first visual detection device arranged at intervals, and the relative tilt angle of the first visual detection device can be adjusted.

[0010] The inner wall of the carrier is provided with a first strip light source;

[0011] A lifting device is provided, wherein the carrier is mounted on the lifting device, and the lifting device is used to drive the carrier to move vertically.

[0012] In practical design, the relative position of the carrier can be adjusted according to different products, thereby achieving relative position adjustment of the carrier. At the same time, through the cooperation of the first strip light source and the first vision detection device, the relative image acquisition point can be adjusted according to the height of the product, thereby achieving detection of the bottom surface of the product and effectively improving the detection accuracy.
