Description
Technical field
The utility model relates to a kind of body in white welder welded manually, especially relates to a kind of integral type medium frequency inverter and hangs soldering turret welding spot counter.
Background technology
Welding equipment assembly is the key that vehicle body is shaped, body of a motor car welding equipment mainly adopts resistance spot welding, spot welding is divided into welding manually and robot automation's welding, welding is manually main at present adopts weldering control and manual soldering turret, owing to being older generation's product, itself is no-welding-spot tally function also, like this when producing some large welding equipment assemblies, due to solder joint number more (as 295, main floor solder joint) and artificial randomness, Manufacturing Worker may misremember solder joint number, cause solder skip point phenomenon to occur, affect product quality and client's complaint.
Utility model content
The utility model provides integral type medium frequency inverter and hangs soldering turret welding spot counter, and count for examination and controlling solder joint, prevent from missing solder joint, add workman's reminding effect, its technical scheme is as described below:
A kind of integral type medium frequency inverter hangs soldering turret welding spot counter, comprise control device and coupled display device, signal pickup assembly, described signal pickup assembly comprises the magnetic sensor being placed on medium frequency inverter soldering turret ad-hoc location, and described control device is connected with welding switch.
Described control device adopts single-chip microcomputer or PLC.
Also comprise the hummer for reporting to the police.
Described PLC comprises the load module, data memory module, comparison module, microprocessor module, counting module, output module, the soldering turret control module that connect successively.
Described output module and solder joint count display module and are connected.
Described soldering turret control module is connected with welding switch.
The welding that described integral type medium frequency inverter suspension soldering turret welding spot counter can record soldering turret is counted, avoid weldment solder skip point, replace postwelding people number solder joint, add workman's reminding effect, fundamentally solve the problem of resistance spot welding welding leak source, improve process control capabilities, providing powerful guarantee for controlling body in white intensity.And decrease the randomness and checker's quantity that add workman, saved cost of labor, improve product quality and customer satisfaction.
Accompanying drawing explanation
Fig. 1 is the structural representation that described integral type medium frequency inverter hangs soldering turret welding spot counter;
Fig. 2 is the operating diagram that described integral type medium frequency inverter hangs soldering turret welding spot counter;
Fig. 3 is the I/O schematic diagram of described PLC;
Fig. 4 is the wiring diagram of described PLC;
Fig. 5 is the control enclosure layout that described integral type medium frequency inverter hangs soldering turret welding spot counter.
Embodiment
Described integral type medium frequency inverter hangs soldering turret welding spot counter as shown in Figure 1, comprise control device and coupled display device, signal pickup assembly and peripheral circuit thereof, and provide the power module of electric energy for above each device, described signal pickup assembly comprises the magnetic sensor being placed on medium frequency inverter soldering turret ad-hoc location (containing shielding measure), become electric signal to feed back to control device for induced field change transitions, described control device is connected with welding switch.
Described control device adopts PLC, if adopt single-chip microcomputer, its function is identical with PLC.
Described PLC is programmable memory, for its internally stored program, actuating logic computing, sequential control, regularly, counting and the user oriented instruction such as arithmetical operation, and control various types of machinery or production run by numeral or analog pattern input/output, comprise the load module, data memory module, comparison module, microprocessor module, counting module, output module, the soldering turret control module that connect successively.
Described output module and solder joint count display module and are connected, and described display module adopts LED charactron conventional in Industry Control to do display element, dependable performance.Described soldering turret control module is connected with welding switch.
Described welding spot counter working-flow as shown in Figure 2, first starts counter, then starts welding switch, the electromagnetic switch of described magnetic sensor gathers electric signal, and by Signal transmissions to PLC, then PLC counting adds one, and compare in setting value, if be less than setting value, then welding continues operation, if be not less than setting value, then cut off welding switch, technology device, next can hand-reset by buzzer warning, workpiece counting adds one, release welding.
As shown in Figure 3,4, be I/O schematic diagram and the wiring diagram of PLC respectively, Fig. 5 is then control enclosure layout.
Operationally, step is: 1, welding spot counter count signal takes from the magnetic sensor near soldering turret transformer, the electric signal that the changes of magnetic field gathering welding transformer generates, and often weld a bit, counter adds 1 automatically, stored count;
2, weld timer can set prevalue (technological requirement welding is counted) and show, when welding times reaches setting value, welding counter alarm lamp is bright, and sends interlock signal to welding machine, and welding stops;
3, when welding spot counter reaches preset set point, by reset button, counter number resets, countdown warning pilot lamp goes out, and workpiece counting adds 1, if actual welding is counted unequal with preset set point simultaneously, then counter cannot reset, then judge leak source, then need to add workman and again check solder joint, after consistent with preset set point, just can carry out next part welding;
4, start welding, counter restarts counting.
The weld nugget counter of the utility model exploitation is mainly used in integral type medium frequency inverter and hangs soldering turret, owing to being different from the big current of secondary cable when split type power frequency soldering turret welds, during data acquisition, the changes of magnetic field caused less than electric current responded to by magnetic sensor at secondary cable place, suitable takes signal location or method so need to find.
The utility model can record often counts the welding of welding gun, reaches setting value and reports to the police, add workman's reminding effect, thus increase work efficiency, ensure product quality.Utilize welding spot counter and original weldering control, soldering turret to combine simultaneously, implement mistake proofing anti-error.
