A visual detection apparatus

Abstract

A visual detection apparatus is disclosed in embodiments of the invention. The visual detection apparatus includes a supporting device, a first sliding device, a light source device, a camera device,a first adjusting device and a second adjusting device. The supporting device includes a horizontal supporting bar and vertical supporting bars perpendicular to the horizontal supporting bar. The first sliding device is disposed on the horizontal supporting bar, and is parallel to the horizontal supporting bar. The first adjusting device is connected to the light source device and the first sliding device separately. The second adjusting device is connected to the camera device and the first sliding device separately. The first and second adjusting devices control the light source device and the camera device to move up and down through a screw adjusting manner respectively. Through this way, adjustment precision is higher, and the camera device and the light source device are stabler in an up-down adjusting process, thus saving time and labor.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of visual inspection, and in particular, to a visual inspection device. Background technique [0002] With the popularity of smart terminals, two-dimensional codes are gradually becoming popular. Two-dimensional codes, also known as two-dimensional barcodes, are black and white graphics distributed on a plane with specific geometric figures according to certain rules. A key to information data. However, during the printing process of the two-dimensional code, due to the influence of various factors such as mechanical precision and production technology, different types of QR code defects will appear on the surface of the printed matter. Therefore, it is necessary to detect these printed QR codes by the detection structure. In order to carry out the next step of packaging and other processes. [0003] In the process of realizing the present invention, the inventor of the present in...

However, during the printing process of the two-dimensional code, due to the influence of various factors such as mechanical precision and production technology, different types of QR code defects will appear on the surface of the printed matter. Therefore, it is necessary to detect these printed QR codes by the detection structure. In order to carry out the next step of packaging and other processes

[0003] In the process of realizing the present invention, the inventor of the present invention found that in the prior art, the distance between the camera lens and the light source and the substrate is adjusted by adjusting the up and down movement of the linear slide rail, and the moving distance of the linear slide rail up and down Difficult to control, adjustment is more time-consuming and energy-consuming
