The SQM works like a linear camera that takes the form of an (A-shaped ring and the wire thread passes through it) image and is used for fine wire threads from 10 micrometers to 2 mm and in two fine and ultra fine models. This system with 0.4 point camera in a peripheral circle with a frequency of about 300,000 times per second has provided an advanced technology with low cost and much higher efficiency than existing technologies.
The size of each spot camera is proportional to the cross section of the wire. Also, this system performs all the necessary calculations, including: identifying the locations of defects and determining their coordinates and necessary warnings, in a completely digital way.
This set is independently connected to a computer device in order to provide the possibility of entering basic information, setting the parameters of displaying the image of the outer surface of the wire strand on the monitor, performing statistical calculations, providing production quality reports and maintenance instructions) The prototype of this invention in July 2004 has been registered). New models for larger sections and with higher resolution and lower speed will be released in 2016.
The surface quality of wire strands is important from several points of view:
Roughness, cracks, bulges and thinning, especially when producing fine stainless steel wires, gold wire, coating and plating and painting of copper wire strands, telecommunication cables and optical fibers, so far there is equipment to identify it with a degree of clarity and There was no high and completely uniform speed. This surface processing system works based on standard image analysis sent from the camera.
Limiting factors when working on fine wires are the resolution of points on the surface of the wire strand, the image frequency, and the exposure system for surface analysis.
The peripheral imaging method covers the entire surface of the wire with a very high resolution and high speed, making it possible to determine the surface quality and the coordinates of the defective points. With the speed of 000 and 300 rounds per second and 64 point cameras 1/1 in one circumference and linear speed of 300 meters per second (0.8 times 1 (Pitch) kilometers per minute), the degree of resolution will be mm.
Considering the linear feed of the wire and the peripheral scanning speed, the measurement is done in two dimensions and finally leads to providing a two-dimensional image of the surface of the wire under investigation. By transferring this image to the computer, a view of the surface of the wire strand, especially the identification of defective points and their analysis becomes possible.
According to the statistics obtained from numerous reviews, this system has a long lifespan. Since the maintenance of optical systems in unsuitable environments requires special care, in this system it can be easily protected from possible problems by blowing clean air to remove dust, steam or suspended particles from the inner wall of the glass tube. did
