Imaging device for sorting machine

Abstract

The invention discloses an imaging device for a sorting machine. The imaging device is used for imaging a fastener on a transparent turntable of the sorting machine. The imaging device comprises a vertical imaging part and a horizontal imaging part, wherein the vertical imaging part comprises a vertical imaging camera which is used for shooting an image of the fastener on the transparent turntable along the vertical direction; the horizontal imaging part comprises at least one horizontal imaging camera used for shooting the image of the fastener on the transparent turntable along the horizontal direction; the horizontal imaging part and the vertical imaging part are arranged along the rotating direction of the transparent turntable. According to the imaging device, a camera imaging technique is adopted for imaging the fastener; the size of the fastener can be reasonably collected; the detection precision is promoted.

Description

technical field [0001] The invention relates to a sorter imaging device. Background technique [0002] At present, the sorting machine is an important testing equipment and sorting device for hardware, fasteners, electronic components and other products. It is used to separate unqualified and uncertain products from qualified products in these products. [0003] The sorting machines in the prior art all rely on adjusting the frequency of the vibrating plate, the speed of the conveyor belt or adding special conveying plate components to make the feeding speed uniform. The distance between the parts of the dial is a certain value, and then the signal of the measured part is sensed by the sensor and transmitted to the PLC. At the same time, the PLC reads the current position of the rotary encoder and saves it. The image of the parts is collected, and the results of the image processing system are sent to the PLC. The PLC performs internal data comparison and transmits the cont...

Problems solved by technology

During this process, due to the time difference between the host computer and the PLC in data exchange, the accuracy of image acquisition will also deteriorate, which will affect the final sorting results and easily cause wrong selection of parts. For obvious reasons, and in order to keep the distance between parts consistent with this detection method, it is necessary to increase the program control or conveying parts at the part delivery end, which greatly increases the cost

No matter in terms of economy or operability, this detection method cannot achieve more accurate image acquisition and achieve the effect of precise sorting of parts
