Automatic debugging device and method for dish-washing machine pressure switch

Abstract

The invention relates to an automatic debugging device and method for a dish-washing machine pressure switch. The automatic debugging device and method is used for debugging of the pressure switch of a dish-washing machine. The automatic debugging device comprises a rack, a control panel, a programmable logic controller (PLC), a servo controller, an electromagnetic valve, a compressed air pressure regulating valve, an air cylinder, a high-pressure tank, a constant pressure tank, a fixing device, an adjusting device and a constant pressure device. According to the method, the fixing device, the adjusting device, the constant pressure device, the servo controller and the electromagnetic valve are correspondingly controlled by the PLC to finish debugging of the pressure switch. The automatic debugging device and method for the dish-washing machine pressure switch has the advantages that the structure is reasonable, debugging of high and low pressure trigger points of the pressure switch can be automatically and accurately achieved, the operation is simple, the efficiency is high, and the deviation of debugging qualities is small.

Description

technical field [0001] The invention relates to automatic debugging of a dishwasher pressure switch, in particular to a device and method for slowly debugging a trigger point from a high value to a low value or from a low value to a high value. Background technique [0002] With the development of society, the work of washing dishes has been automated through machines, and a pressure switch is installed in the dishwasher to strictly control the internal pressure and water level of the dishwasher. After the pressure switch is produced, It is also necessary to debug the values ​​of the high-voltage trigger point and the low-voltage trigger point, and the common debugging is to rely on workers to rely on experience to find the trigger point, pressurize, and then find the trigger point. The method has the disadvantages of relying on the actual experience of the workers, and the operation is complicated, the efficiency is low, and the debugging quality deviation is large. Conte...
