Scanning device for product surface detection and assembling method thereof

Abstract

The invention discloses a scanning device for product surface detection and an assembling method thereof, and relates to the technical field of product surface scanning devices. The scanning device comprises a mounting support, a diaphragm component is fixed to one side of the mounting support, and a plurality of channels penetrate through the surface of the diaphragm component and are used for allowing reflected light generated by the surface of a to-be-detected product to pass through so as to form a folded light path; and a light path reflecting component is further arranged on one side of the mounting support. Light can pass through the diaphragm component to form a light path, stray light is effectively avoided, the diaphragm component is used in cooperation with the light path reflection component, an original light path is divided into a plurality of light paths, the purpose of reducing the size of the whole device is achieved, meanwhile, the internal structure of the scanning device is compact, the scanning device has high stability in use. The mounting bracket fixedly connected with the diaphragm component and the reflecting component respectively is not in contact with the cover plate and the side plate, so that the cover plate and the side plate can be prevented from colliding with the diaphragm component and the reflecting component.

Description

technical field [0001] The invention relates to the technical field of product surface scanning devices, in particular to a scanning device for product surface detection and an assembly method thereof. Background technique [0002] CCD sensor, made of a high-sensitivity semiconductor material, can convert light into electric charge, and convert it into digital signal through analog-to-digital converter for computer to process it. At present, it has been widely used in the detection of surface defects of industrial products. Especially for the detection of various defects on the product surface. [0003] At present, when detecting defects on the surface of an object, a scanning device with a CCD camera is usually used, and the light source is used to irradiate the surface of the object to make the light path reflect from the surface of the object, and then the CCD collects the reflected light path. However, the currently used scanning device is for Ensuring that the amount ...

[0003] At present, when detecting defects on the surface of an object, a scanning device with a CCD camera is usually used, and the light source is used to irradiate the surface of the object to make the light path reflect from the surface of the object, and then the CCD collects the reflected light path. However, the currently used scanning device is for Ensuring that the amount of light collected is sufficient and the path of the light is long enough will lead to a large volume of the entire device, which will seriously occupy the space of the detection environment, and it is also unstable and easy to shake during use
