The plating machine has two states, which are fully automatic production line and manual one. When the automatic state failure, will use the manual control, after the trouble removing, then resume automatic operation, that means will not because of a single failure to affect the whole production line, resulting in shut down. Production line in operation face with manual operation box, that enabling manual/automatic conversion, system start/stop, and the operation of translation, lifting; under the condition of crane running, there has a self-diagnostic function to prevent the failure occurrence of crane translation and lifting out of limit, and motor overheating. Automatic electroplating production line is based on the difference between size and capacity of the products to design different loading patterns and run beat, to formation corresponding run program, the crane will according to system requirements to move automatically, thus to realize the automation of the production process running. Complete electrical control system adopts PLC and IPC (optional) control, which has strong anti-jamming capability, to ensure long-term continuous and stable operation. The system has functions of good man-machine interface and database, interface with full English display, simple operation, achievable operation, tips and help functions etc.. Created real time and historical two databases in the computer. The historical database can achieved technical parameters history record and storage function, which will easy to trace product quality and production conditions for the management analysis. Real time database can realize to display entire production line running for dynamic process, to monitor the parameters. Through the database functions can complete variety statistical reports of records and generates.
Improving the automation control degree of plating equipment, not only can effectively improve production efficiency, reduce labor intensity, but also according to product characteristics to realize the pertinence structural design that is traditional manual production can not achieve, then to improve product electroplating quality. For example, barrel plating production line, automatic operation design of auto switch barrel doors and swing drum design. In the production process, when the barrel rotated to the door facing the anode, the barrel door will open, so that the liquor inside the barrel will be updated; further more, because there is no shield from barrel door, the power lines remain relatively smooth, under the constant pressure, the plating current density increases accordingly, which can speed up the coating deposition rate, and effectively avoid the workpiece appear problem of “bucket print”. Reduce energy consumption, reduce pollutant emissions and adapt to cleaner production requirements. The defination of cleaner production recognized from internationally recognized United Nations UNEP is: Cleaner production is a new kind of creative thinking, the thinking continue to apply overall preventive environmental strategy to production processes, products and services, in order to increase ecological efficiency and reduce human and environmental risks.
Regarding the production process, it is required to save raw materials and energy, to eliminate toxic raw materials, to reducte quatity and toxicity of all rubbish; refer to products, it is required to reduce adverse effect of full life circle which from raw material extraction to final products disposal; for service, it is required to bring environmental factors into design and provided services. The major contents of cleaner production including: cleaning energy; cleaning production processes; cleaning products. For the electroplating industry, water conservation technology and design, solution regeneration technology and so will be more and more popular. In the production line design process, using counter current rinsing, dripping delay, the receiving fluid design etc. all can reduce the waste of resource effectively in the production process. For renewable plating solution technology, due to solution effective recovery and regeneration, not only saves raw materials, but also reduce the amount of waste water treatment, and thus renewable plating solution technology also become one of the major trend for plating development. Improve the quality of electroplating workshop operating environment, strengthen the monitoring of harmful gases, is another important reflection of electroplating equipment user-friendly design. The acid mist, alkali mist, air containing cyanide and chrome anhydride generated in electroplating workshop will all bring serious harm to human body.
In addition to the exhaust system design, harmful gas real-time monitoring design will be an important measure to protect the operating worker’s health, when the operating environment contained harmful gas concentration exceeds the set value, the system will automatically alarm, causing the operator alert, thus protecting operator’s health. Electro plating waste water is an principle element causing environmental pollution. Ideally electroplating waste water treatment model is zero discharge of sewage systems, to achieve zero discharge of wastewater requires strict classification of harmful substances targeted for different treatment. But plating wastewater harmful substances contained species are very complex, in order to manage spilt-flow, the cost will be very high, which is electroplating enterprises unbearable. However, the zero-emission is the development direction of electroplating waste water treatment, along with increasingly stringent environmental requirements and water treatment technology, this technology must be developed and will eventually spread. Development of modern manufacturing needs, determine the electroplating industry must be present and will continue long-term development. However, compared with other professions, our electroplating manufacturing level and the international level there is still a significant gap. The electroplating industry, is inseparable from the improving of electroplating equipment manufacturing technology, so to meet the technical requirements of modern electroplating, more humane and intelligent technology development will become an inevitable trend in the development of electroplating equipment.
