Background
In the sheet metal industry, sheet metal spraying is an indispensable and particularly important process link in the machining process, and the spraying effect can directly influence the performance and quality of sheet metal products in later period.
The current popular spraying operation mode is as follows: setting field process parameters of a plurality of medicine water tanks, the temperature of a baking oven and the running speed of a spraying line according to the type of materials and a person following the line; a plurality of pools with different pH values and a baking oven are arranged on the spraying workshop, the liquid medicine in the pools is pumped up to be sprayed onto the metal plates through nozzles, and finally the liquid medicine is dried through the baking oven; a person on the line is regularly checked for on-site process parameters and baking furnace temperature of the multiple spraying line liquid medicine pools, liquid medicine is manually added according to the detection result, and the furnace temperature is adjusted; when the field process parameter of a certain liquid medicine pool exceeds the range or the furnace temperature of a certain baking furnace exceeds the range, the operation of the spraying line needs to be manually stopped; the person who follows the line adds liquid medicine to the pond that corresponds, will bake out the stove temperature adjustment to within the scope, restarts this and sprays the line operation.
In the current working mode, the following problems cannot be solved:
1) the material type, the field process parameters of the liquid medicine pool, the furnace temperature of the baking furnace and the running speed of the spraying line are judged and set by following line personnel. The operation is not foolproof, and once the metal plate sprayed by mistake is scrapped.
2) The automation degree is low, and a person who follows the line needs to check the field process parameters, the baking furnace temperature and the spraying line running speed of the pesticide pools of the plurality of spraying lines regularly. If the inspection of a person on the line is not timely, the speed of adding the liquid medicine and adjusting the temperature of the furnace is slow, the field process parameters of some liquid medicine pools or the temperature of the baking furnace cannot reach the standard, and if the spraying line continues to operate, the performance and the quality of the produced sheet metal product cannot meet the requirements and cannot be guaranteed.
3) For various parameter indexes, the adjustment time of the processor is not intelligent. The short adjustment time can lead to the need of greatly improving the rated power and capacity of the dosing machine, the water purifier and the burner, and increase unnecessary cost. The adjusting time is too long, and the time for intervention adjustment of a person following the line is too short under the condition that the automatic adjustment of the processor fails, so that the person following the line is not adjusted and the line is stopped.
4) Often stop the line, need follow the line personnel and detect and adjust liquid medicine to a plurality of liquid medicine ponds during stopping the line, the adjustment bakes out the stove temperature, and at this moment all workman can only wait for, wait to spray all workman's ability work after the line resumes operation, lead to the human cost high, production efficiency reduces, also increased the cost in intangible.
5) Each spraying line needs to be managed and controlled independently, and unified management and control cannot be achieved.
