Scanning device for integrated product surface detection and assembling method thereof

Abstract

The invention discloses a scanning device for integrated product surface detection and an assembling method thereof, and relates to the technical field of product surface detection, and the scanning device comprises a light emitting mechanism used for emitting light to the surface of a to-be-detected product and a reflected light receiving mechanism used for receiving light reflected by the surface of the product; the light-emitting mechanism comprises a first fixing support, and a plurality of channels are formed in the upper surface of the first diaphragm component in a penetrating mode and used for allowing light to pass through so as to form a folded light path. The direction of a light path is changed, and a long light path is divided into a plurality of short light paths, so that each structure is compact, the size of the whole device is reduced, convenience and stability in use are ensured, and the first fixing bracket and the second fixing bracket playing a role in fixing are not in contact with the first frame and the second frame on the outer side of the first fixing bracket and the second fixing bracket, the stability of the light-emitting mechanism and the reflected light receiving mechanism in the using process can be effectively guaranteed, and the light-emitting mechanism and the reflected light receiving mechanism are prevented from being influenced by collision of the first frame, the second frame and side plates on the first frame and the second frame.

Description

technical field [0001] The invention relates to the technical field of product surface detection, in particular to an integrated scanning device for product surface detection and an assembly method thereof. Background technique [0002] As a light sensor, a CCD sensor is made of a high-sensitivity semiconductor material, which can convert light into electric charge, and convert it into a digital signal through an analog-to-digital converter, which can be processed by a computer. 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 reflect the light path from the surface of the object, and then the optical sensor collects the reflected light path. However, the currentl...

[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 reflect the light path from the surface of the object, and then the optical sensor collects the reflected light path. However, the currently used scanning device In order to ensure that the amount of light collected is sufficient and the path of the light is long enough, the entire device is bulky, which will seriously occupy the space of the detection environment, and it is also unstable and easy to shake during use.
