Detailed description of the invention
With reference to accompanying drawing, the utility model single-side machine automatic glue control system embodiment is described further.
A kind of single-side machine automatic glue control system, comprise power cabinet, PLC and benefit gluing mechanism, benefit gluing mechanism comprises scrapes glue coating wheel, PLC controls glue consumption by controlling to scrape figure rubber tire, thus ensure the quality of product and control cost, mend the control signal operation that gluing mechanism receives PLC, be connected with between PLC and benefit gluing mechanism for the protection of PLC and the protection circuit 100 mending gluing mechanism, protection circuit 100 comprises the first solid-state relay coil KA1, first solid-state relay coil KA1 one end is coupled to the output of PLC, the other end is coupled to the common port of PLC, the output end voltage 24V of PLC, common port voltage 0V, the normally opened contact K switch A1 of the first solid-state relay, in response to the first solid-state relay coil KA1, be coupled to external power source, when the first solid-state relay coil KA1 works, the normally opened contact K switch A1 of the first solid-state relay closes, contactor coil KM works, contactor coil KM, and one end is coupled to the normally opened contact K switch A1 of the first solid-state relay, the other end is coupled to external power source, contactor coil KM works, and normal open switch KM closes, and the benefit glue circuit mending gluing mechanism is started working.
Solid-state relay is the contactless electronic beam switch with isolation features, mechanical contact component in switching process, and therefore solid-state relay is except having the function the same with electromagnetic relay, also there is logic circuit compatibility, resistance to mechanical resistant of shaking is impacted, and installation site is unrestricted, has good moistureproof and mildewproof Corrosion Protection, explosion-proof and prevent the performance in ozone pollution also splendid, input power is little, highly sensitive, controls power little, Electro Magnetic Compatibility is good, the low and operating frequency high of noise.Solid-state relay is highly sensitive, and control power little, Electro Magnetic Compatibility is good: the input voltage range of solid-state relay is wider, and driving power is low, can not need to add buffer or driver with most of logical integrated circuit compatibility.Solid-state relay is because adopt solid state device, so switch speed can from several milliseconds to a few microsecond.Solid-state relay does not have contact striking and rebound, thus decreases electromagnetic interference.Great majority exchange and export solid-state relay is a ZVT, and in the conducting of no-voltage place, zero current place turns off, and decreases the unexpected interruption of current waveform, thus decreases switching transient effect.
Solid-state relay is namely when normal work, and chip exists certain power attenuation therein, this loss power determines primarily of solid-state relay output voltage drop and load current product, consumes with the form of generating heat.Therefore the too high meeting of solid-state relay temperature directly has influence on the reliability of solid-state relay work, the failure that can cause and damage.So protection circuit 100 also comprises hot-swap unit 101, hot-swap unit 101 comprises the second solid-state relay coil KA2, and second solid-state relay coil KA2 one end is coupled to the output of PLC, and the other end is coupled to the common port of PLC, hot detecting unit, the output signal that PLC receives hot detecting unit is for controlling the first solid-state relay coil KA1 or the second solid-state relay coil KA2 works, when testing circuit detects that the first solid-state relay coil KA1 is overheated, PLC can make the first solid-state relay coil KA1 quit work, be switched to the second solid-state relay coil KA2 to work simultaneously, then the first solid-state relay coil KA1 can be nature cooling, when the second solid-state relay coil KA2 is overheated, testing circuit also sends detected value, PLC accepts detected value and is switched to use first solid-state relay coil KA1, such first solid-state relay coil KA1 and the second solid-state relay coil KA2 is used alternatingly, one of them solid-state relay coil can be avoided overheated and affect duty or damage, reduce loss, do not affect operating efficiency, the normally opened contact K switch A2 of the second solid-state relay, in response to the second solid-state relay coil KA2, one end is coupled to external circuit, and the other end is coupled to contactor coil KM, mends glue circuit and also normally works, increase work efficiency when can ensure like this to switch.
Hot detecting unit comprises the first temperature sensor 1, in order to detect the temperature output detections value simultaneously of the first solid-state relay coil KA1; Second temperature sensor 2, in order to detect the temperature output detections value simultaneously of the second solid-state relay coil KA2, first temperature sensor 1 is arranged on the first solid-state relay coil KA1 place, second temperature sensor 2 is arranged on the second solid-state relay coil KA2 place, temperature sensor is prior art, and not in this to go forth.
The interlocking unit 102 that the normally-closed contact K switch A2 of normally-closed contact K switch A1 and the second solid-state relay that hot-swap unit 101 comprises the first solid-state relay is formed, the normally-closed contact K switch A1 of the first solid-state relay is in response to the first solid-state relay coil KA1, one end is coupled to the output of PLC, and the other end is coupled to the second solid-state relay coil KA2; The normally-closed contact K switch A2 of the second solid-state relay is in response to the second solid-state relay coil KA2, and one end is coupled to the output of PLC, and the other end is coupled to the first solid-state relay coil KA1.When first solid-state relay coil KA1 works, the normally-closed contact K switch A1 of the first solid-state relay opens, second solid-state relay coil KA2 place circuit disconnects, when can ensure that the first solid-state relay coil KA1 works like this, the second solid-state relay coil KA2 is in idle state, vice versa, thus ensure that one of them solid-state relay coil is in the state of cooling.
Hot-swap unit 101 comprises indicating member 103, and described indicating member 103 comprises the first indicator lamp 3, and described first indicator lamp 3 is used to indicate the first solid-state relay coil KA1 and works; Second indicator lamp 4, described second indicator lamp 4 is used to indicate the first solid-state relay coil KA1 and works.Can be used for observation be which solid-state relay coil is in running order, handled easily.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to the above embodiments, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
