The Pulse liquid filling machine is suitable for image processing to obtain the position information of the circular filling port in the image of the barrel cover surface by calculation, that is, the radius of the filling port, the marking of the center of the filling port and the height of the oil gun. Then, the corresponding position information is transmitted to the stepper motor control system, and the motor control system drives the X-Y-Z axis stepper motor according to the pulse instruction issued by the computer, and drives the oil gun to run above the filling port to realize automatic positioning and filling.
020-34563445The Pulse liquid Filling machine uses CCS high brightness low Angle LED array ring light source lighting, can obtain high contrast image, easy image segmentation processing. The automatic filling machine is composed of industrial camera, monochrome image acquisition card, high brightness and low Angle LED array ring light source, industrial computer, driver, three-coordinate workbench LabVIEW and IMAQVision development platform. The industrial camera CCD captures the image of the detected bucket on the weighing platform of the detection and weighing module in real time and transmits it to the image acquisition card. After digital decoding A/D conversion and other processing, it is transmitted to the computer memory through the I bus for storage.
The image processing program accesses the memory buffer of the retained image. In the process of acquiring and transmitting the image signal, the noise caused by the environmental impact, the interference of electrical signals such as sensors, and the imperfection of transmission channel makes the image degenerate. For the noise in digital images, such as Gaussian noise, salt and pepper noise, uniform distribution noise, there should be noise reduction pretreatment. Image preprocessing improves the visual effect of the image, enhances the clarity of the image, and makes it more conducive to computer processing.
The Filling system uses a fast median filter algorithm to denoise the signal, and then image binarization is used to segment the image. Compared with the similar low-pass linear filter, the median filter can filter the point and coarse line noise in the image, remove binary noise, pulse noise and particle noise, and reduce the random noise without blurring the boundary. It is suitable for image processing to obtain the position information of the circular filling port in the image of the barrel cover surface through calculation, that is, the filling port radius, the filling port center mark and the height of the oil gun. Then, the corresponding position information is transmitted to the stepper motor control system, and the motor control system drives the X-Y-Z axis stepper motor according to the pulse instruction issued by the computer, and drives the oil gun to run above the filling port to realize automatic positioning and filling.
