Electroplating line PLC remote wireless communication control scheme
The PLC remote wireless communication control scheme provided by Jia Hongwei in the automatic electroplating production line has been applied in the production of precision metal parts, electronic products manufacturing, jewelry manufacturing and other fields, the control part adopts good control of PLC and wireless communication module, it makes automatic electroplating production line operation is more stable, more accurate positioning, more perfect function, operation more convenient, the mode of electroplating line intelligent remote monitoring.
By using the good control of JD3 series programmable controller (PLC) and wireless module to realize the system of local and remote control of electroplating production line, using copper plating process, plating finish process of zinc alloy die castings. The plating surface is smooth, the coating is uniform, dense and firm, and the plating quality is improved. A good control PLC control system has strong anti-jamming ability, to adapt to the harsh production environment; using the same system can complete the automatic and manual, single step, single cycle control; AO fault alarm function; according to the scene needs to change the process flexibility; high accuracy; small size; performance the price is relatively low; wireless remote data monitoring etc..
Automatic electroplating production line refers to the plating bath and plating plating automatic lifting device, control device for multifunctional transmission device and electrical control device, detection device, filtration equipment, heating and cooling equipment are combined together according to certain requirements of the electroplating process. The surface of the mechanical products can be obtained with decorative protection and various functional surfaces, and can also be used for repairing the workpieces which are worn and processed. Most of the coating is a single metal or alloy, such as zinc, cadmium, gold, brass, etc., but also the diffusion layer and cladding. Most of the basic materials are iron, steel, stainless steel, etc.. The system of electroplating production line with a straight cantilever crane, crane frame is provided with a lifting hook, and the hook with the driving of a motor control, at the same time with good control of motor speed control inverter amount. When the vehicle is moving, the first fast, close to the station when the slow, when the lifting of the workpiece hook, the first slow after the fast, slow down when the first fast, improve the positioning accuracy and safety. According to the working position, the position switch is arranged on the positioning rail, and the advance and retreat of the vehicle and the lifting of the lifting hook are detected by the travel switch. In order to simply explain the working process of driving in the automatic electroplating production line, the flow of the more than and 20 stations is simplified into four stations, which are divided into the upper and the lower materials, the pretreatment, the plating bath and the post processing station.
The working process is as follows: in the first part of the electroplating production line, the workers will be loaded into the basket of the vehicle and send out the automatic start signal, the basket up to the upper limit of the trip switch to stop, the car began to move forward. According to the production requirements in the need to stay at the top of the stop, and automatically down, hit the lower limit switch to stop. According to the technical requirements in the tank for a period of time after the automatic rise, so the completion of the provisions of each process until the end of the production line, the car will automatically return to the original position, and by the workers loading and unloading parts. In the process of work, there are two kinds of automatic and manual mode of operation, easy to operate. In most cases, select the automatic mode of operation, in the maintenance and special handling of the situation to choose manual operation. The system can also be used for remote data monitoring.
