An automatic detection control system and control method for the edge of ultra-thin silk wire precision arrangement

Abstract

The invention discloses an automatic detection and control system and a control method for the edge of ultra-fine silk thread precision arrangement. The system structure and method of the present invention are very simple, and the implementability and reliability are extremely high. It only needs to install a swing bar in front of the winding reel, and connect the sensor behind the swing bar. ) to add an encoder or other sensors, the two sensors transmit the signal to the controller, and the controller can automatically detect the flatness of the wire on the reel in real time when the wire reaches the edge, as long as there is a slight unevenness on the edge The phenomenon will be transmitted to the controller in real time, and the controller will respond immediately, controlling the speed of the wire unwinder and the timing of the reverse until the wire is completely flat on the edge of the reel.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to an automatic detection control system and a control method for the precise winding edge of ultra-fine wire, which are widely used in the requirements for the winding edge of the winding reel when the ultra-fine wire needs to be wound precisely. flat occasion. Background technique [0002] In industrial control, there are many occasions where it is necessary to evenly wind up wires or wires and other linear objects on the I-shaped wheel or other reels with edges. The reciprocating operation drives the wire or thread to be evenly distributed on the reel. The control of this wire arrangement mechanism has a purely mechanical method and an electromechanical method. It has been widely used in thicker wires, but for ultra-fine Silk thread, if there is no automatic detection and control method, it cannot meet the requirements of normal cable arrangement.

[0002] In industrial control, there are many occasions where it is necessary to evenly wind up wires or wires and other linear objects on the I-shaped wheel or other reels with edges. The reciprocating operation drives the wire or thread to be evenly distributed on the reel. The control of this wire arrangement mechanism has a purely mechanical method and an electromechanical method. It has been widely used in thicker wires, but for ultra-fine Silk thread, if there is no automatic detection and control method, it will not be able to meet the requirements of normal wiring

Using the traditional method, when the silk thread is in the middle of the reel, the spacing and flatness can be easily controlled, so that the thread will not be pressed, and the next process will not be affected when the thread is unwound. The edges of the two ends of the reel cannot be controlled, because the silk thread is ultra-fine, and it is impossible to be at exactly the same point every time due to the influence of the change of the thickness of the reel and different speeds when the edge turns around and changes direction. When there are more and more silk threads, the reel will be deformed to varying degrees. At this time, with the increase of the number of layers of wires, the edges of the two ends of the reel will appear uneven. Because the silk thread is ultra-fine, At this time, the phenomenon of wire pressing is very easy to occur. When the wire is unwound in the next process, it cannot be unwound at the wire pressing place, and the wire is broken and cannot work normally.

Some people use the method of image processing (CCD) to detect the flatness of the edge and then control the method of wiring, but this method has many disadvantages. First, the cost is high. The cost of the CCD system itself is very high. Two cameras must be installed to increase the cost; second, the production environment of this kind of silk thread is generally harsh, with a lot of dust and corrosion, and the camera cannot work normally for a long time in this environment, and the maintenance cost is extremely high. promotional use
