Abstract
The utility model discloses an error correction device for avoiding welding error actions after vehicle type conversion, which comprises a welding gun handle switch. The error correction device is characterized in that the welding gun handle switch is in connection in series with a vehicle type switcher; the vehicle type switcher is connected with a relay; the input of the relay is connected witha main control unit; the main control unit is used for inputting and outputting vehicle type signals and providing warning signals, comparing and recognizing vehicle type switchers, controlling and selecting vehicle type manufacture signals, and controlling the output of signals of relay actions. The utility model better solves the problem of organic combination of manufacture of different vehicletypes and vehicle type switching control of the welding gun during multi-vehicle-type collinear welding manufacture, and avoids error actions during welding caused by different vehicle types.
Description
Technical field
The utility model belongs to vehicle production operation control, is specifically related to be welded control device when producing of a kind of multi-vehicle-type conllinear.
Background technology
The welding of present domestic vehicle body is mainly welded by welding machine and is finished, and wherein welding portion is mainly by welding and robot weld two parts automatically and form manually.Because the thick difference of vehicle and metal plate, the welding parameter of its setting also is different with anchor clamps.Therefore when multi-vehicle-type welding conllinear is produced, need change the welding of different automobile types.Be not easy to weld if carry out the vehicle conversion, produce substandard product with wrong parameter; And along with the continuous lifting of company's production capacity, the vehicle machine of importing also can increase gradually, and productive temp is also more and more faster, so also more and more higher to operative employee's requirement.Vehicle conversion on the welding and assembling production lines now relies on fully and manually finishes, and can produce mistake unavoidably, so direct quality that influences product under so fast productive temp.And do not have effective way to address the above problem at present.
Summary of the invention
After being to provide a kind of vehicle to change, the purpose of this utility model prevents to weld the error correction device of misoperation, to address the above problem.
The technical solution of the utility model is: it comprises the torch handle switch, it is characterized in that torch handle switch series connection vehicle change-over switch, and the vehicle change-over switch connects relay, and the input of relay is connected to main control unit; Main control unit is used for input and output vehicle signal and provides alarm signal, relatively discerns the control of vehicle change-over switch and selects production vehicle signal, the signal output of control relay action.
Described main control unit adopts programmable controller PLC.
This device is selected control by the vehicle of main control unit, when same working terminal is produced different vehicles, when the vehicle that the vehicle selector switch of selecting to get ready controller when the vehicle in the welding machine on working terminal conversion and main control unit are exported is inequality, all welding gun akinesias of this working terminal, when having only the vehicle of selecting to get ready controller when the vehicle in the welding machine of this working terminal conversion to select the vehicle exported with main control unit identical, all welding guns of this website could move; Vehicle in same erect-position is identical, but the vehicle between erect-position and the erect-position is not simultaneously, and all welding guns of each website can both normally use.This device has well solved the multi-vehicle-type conllinear and has been welded when producing, and the combination of production different automobile types and welding gun vehicle conversion and control is when avoiding welding, because the difference of vehicle causes misoperation.
Description of drawings
Prevent after the conversion of Fig. 1 vehicle that the error correction device that welds misoperation from constituting schematic diagram.
Fig. 2 programmable controller controls principle schematic.
Fig. 3 vehicle shows schematic diagram.
Fig. 4 programmable controller controls flow chart.
The specific embodiment
As shown in Figure 1, 2, main control unit adopts programmable controller PLC, and it is connected with computer (PC) by communication interface RS232.The output of programmable controller is connected to relay, and the output of relay is connected to the vehicle change-over switch, and the vehicle change-over switch is connected with welding gun torch handle switch.The output of programmable controller also connects vehicle displaying alarm and vehicle display lamp.01～32 is in five stations among Fig. 1, and the vehicle change-over switch control box of 6 welding guns is arranged in each station.
As shown in Figure 4, programmable controller PLC is according to the vehicle signal in the production schedule of input, when the selected vehicle signal of vehicle change-over switch and programmable controller PLC were inconsistent, programmable controller PLC disconnected relay, and the switch motion of welding gun torch handle is invalid; When the selected vehicle signal of vehicle change-over switch is consistent with programmable controller PLC; Making the terminal on its corresponding output module is ON.After the output module terminal was ON, we just can obtain my on power supply of direct current of a 24V.So, we just can utilize this 24V dc source to control the break-make of 24V DC relay coil.Two disconnected being connected in the bat-handle switch line of welding gun of relay normally open point.That is to say, only meet the logical operation of PLC, welding machine bat-handle switch break-make just effective.
The vehicle change-over switch is realized the selection of different automobile types by the conversion of knob between different gears, what connect switch enclosure and PLC is 10 core aviation socket cables, after choosing different vehicles, different electric current and the pressure of PLC control output, and on vehicle conversion indicator lamp, show.
Vehicle display screen Fig. 3, vehicle display lamp show according to station and vehicle and form; Station comprises five stations of SPOT1～SPOT5 among the figure, and vehicle is divided into WB, UH, WO and four kinds of vehicles of SP.Design formed by the LED lamp of several 24V direct currents.Terminal on the output module of programmable controller PLC is received on the LED lamp in the display screen, provided 24V dc source to it, and can control the light on and off of LED lamp by the PLC computing.Display screen panel is marked with the title of code name He all erect-positions of all vehicles.It mainly is to be used for pointing out what current vehicle is, or what vehicle what changing be, or the vehicle of which erect-position to change ground wrong.
According to the PLC program of establishment, this system can realize the function of 4 aspects.(1)。When this streamline began to change vehicle, the buzzer on the main control unit can send discontinuity and report to the police, and played suggesting effect.(2)。In same station, if there is the vehicle welding condition of a welding gun that mistake is set, buzzer on main control box Fig. 1 will have yowl sound so, and can clearly know mistake where occurred by the erect-position that shows on display screen Fig. 2, and which is incorrect the welding condition of welding gun.Thereby remind operator to be modified to correct welding condition, guarantee the welding quality of product.(3)。When the vehicle of erect-position and erect-position is different, can not influence production operation.That is to say that when streamline was changed trains type, the vehicle of erect-position SPOT1 was WQ, the vehicle of erect-position SPOT2 is UH, though vehicle is different, they are erect-position and unaffected separately, and need not wait until could production operation when whole streamline all changes same model into.(4)。When display screen is changed in vehicle, can well-known demonstration which erect-position change vehicle, replacing be which kind of vehicle.So both made operator know what vehicle this changes, and the manager had been grasped in the very first time produce dynamically.
