Embodiment Construction

[0046] The following is a further detailed description through specific embodiments:

[0047] like figure 1 As shown, a workpiece surface defect detection system includes a frame 1 , a transmission device, an image acquisition device, an image summarization module and a distribution device 8 . The conveyor is mounted on the frame 1, including conveyor belts for placing workpieces. The rack 1 is provided with a reading device 2 on the rear left of the conveyor belt. The reading device 2 is used to read the RFID tags on the surface of the workpiece. Each workpiece has a unique RFID tag, and each RFID tag also corresponds to a unique workpiece. There are two image acquisition devices, namely the first image acquisition device 3 on the left and the second image acquisition device 4 on the right; each image acquisition device includes a light source emitter 9 and a light sensing board 10, and the frame 1 is fixed with The first support rod 11 and the second support rod 12, the fi...

Abstract

The invention belongs to the field of industrial detection, and provides a workpiece surface defect detection system, which aims to solve the problem that fuzzy distortion occurs when a camera is directly used for acquiring a surface image of a moving workpiece in the prior art. Theworkpiece surface defect detection system comprises a rack, a conveying device, an image acquisition device and a distribution device; the image acquisition device is located above the conveying device and comprises a light source emitter and a light induction plate, and the light induction plate comprises a storagemodule, a comparison module, a control module and a plurality of photosensitive sensors; the light source emitter comprises a controller and a plurality of light source lamps; the photosensitive sensor senses the current light intensity information of the reflected light from the light source lamp to the surface of the workpiece and sends the current light intensity information and the photosensitive mark information to the comparison module; the comparison module finds corresponding standard light intensity range information from the storage module according to the photosensitive mark information, and when the current light intensity information does not belong to the standard light intensity range information, the control module controls the distribution device to separate the current workpiece from other workpieces.

Description

technical field [0001] The invention belongs to the field of industrial detection, in particular to a workpiece surface defect detection system. Background technique [0002] The workpiece is an integral part of the precision instrument, and its surface quality, shape and structure have a great influence on the performance of the instrument. In the process of workpiece processing, transportation and assembly, the change of tool stroke and wear, the material characteristics of the workpiece itself, the friction and collision between workpieces and other factors will cause defects such as scratches, convex powder, bumps and cracks on the surface of the workpiece. It affects the beauty of the workpiece, and also affects its performance, and even brings major safety hazards to the instrument. . [0003] At present, with the maturity of image processing technology, industrial cameras are usually used to take pictures of the surface of the workpiece, and then the images obtained...
