Design Of Composite Gas Cylinder Winding And UV Curing Control System

Compared with traditional gas cylinders,composite gas cylinders have the advantages of high strength,corrosion resistance and light weight,which are widely used in various fields of industrial and civil production.At present,composite gas cylinders are mainly formed by winding and heating curing processes,in which the pattern design of cylinder winding and the trajectory of winding machine have great influence on the production efficiency of composite gas cylinders.In addition,the traditional heating and curing process leads to long curing time and high energy consumption of composite cylinders.UV curing has the advantages of low energy consumption and short curing time compared with traditional heating and curing.The thickness of the composite material is the main factor affecting the UV curing effect,and the thickness of the cylindrical section and the head of the cylinder after winding is different,so the winding pattern design is studied and the influence law of yarn width and pole hole size on the thickness of the winding layer is analyzed to determine the UV curing process according to the thickness variation of the winding layer.The effect of winding layer thickness on winding pattern is also considered,and the winding pattern design is based on the updated cylinder profile after winding layer thickness,so as to obtain accurate winding angle and stable fiber winding pattern.In order to improve the cylinder winding efficiency,transition winding is adopted to achieve a smooth transition between different winding methods to achieve continuous winding of gas cylinders.In order to improve the smoothness and smoothness of the winding machine trajectory and the efficiency of fiber winding gas cylinders,the trajectory of the drop point is obtained through the pattern design of composite gas cylinders,and then the influence of different envelope forms of different winding methods on the trajectory of the winding machine is analyzed separately,so that a better trajectory of gas cylinder winding operation can be obtained.Five times polynomial trajectory planning is carried out and segmented polynomial trajectory planning method is proposed to optimize the winding machine motion time by using improved particle swarm algorithm to realize efficient fiber winding molding of composite gas cylinders.To determine the light intensity and curing time required for the UV curing process of composite gas cylinders,the UV curing kinetics were studied,and the light intensity required for UV curing was determined according to the thickness of the cylinder winding layer,and the cylindrical section and the head of the cylinder were cured simultaneously by controlling the light intensity in different areas of the UV LED.In order to realize the control of curing time and light intensity,a UV LED driving system is designed,using STM32 as the main control chip,and the PWM duty cycle is adjusted to change the output current of the constant current source,which in turn adjusts the light intensity of the UV LED to realize the synchronous curing of cylindrical section and head of gas cylinder.Finally,the experimental platform for winding and UV curing of composite gas cylinders using TRIO motion controller and STM32 microcontroller as the core controller,Yaskawa servo driver and motor as the actuator of the winding machine,and UV LED as the UV curing light source is built,and the upper and lower software of the control system is designed.The winding,curing and testing experiments of composite gas cylinders were conducted.The findings demonstrate that the proposed UV curing composite gas cylinder molding process is workable,that the designed gas cylinder winding pattern and the winding machine trajectory optimization method increase production efficiency,and that UV curing reduces the curing time and enhances the molding efficiency of composite gas cylinders.
