Abstract
The utility model relates to an error correction device for spot welding and missed welding, and belongs to parts of a fixation spot welding machine. A power supply is connected with a PLC (programmable logic controller) which is connected with a signal lamp and a buzzer, and a point-aiming singlechip is connected with the PLC. The error correction device has the advantages of novel structure, convenient use and efficient avoidance of missed welding.
Description
Technical field
The utility model belongs to the parts of point of fixity welding machine, is used for fixing on the spot welder, the generation of anti-leak-stopping weldering.
Background technology
In the auto parts and components assembly, welding screw, nut is more, is easy to generate weldering when adopting manual spot welding with Louing, causes product defective, and generation is done over again or reprocessed, and the serious client that causes complains.
Summary of the invention
The utility model provides a kind of spot welding to leak the weldering error correction device, is easy to generate Lou weldering when adopting manual spot welding to solve, and causes product defective, produces the problem of doing over again or reprocessing.The technical scheme that the utility model is taked is: power supply is connected with the PLC controller, and this PLC controller is connected with signal lamp, hummer, sits the some single-chip microcomputer and is connected with the PLC controller.
Employing sets in advance the method for spot welding quantity, and when number of welds reached counting of regulation, welding machine was reported to the police and disconnected foot-operated signal.When welding machine was reported to the police, number of spare parts was correct, and number of welds is also correct, does not then leak weldering.When welding machine was reported to the police, number of spare parts was incorrect or count incorrectly, then leaks weldering.
The utility model advantage is a novel structure, and is easy to use, can effectively avoid the leak generation of weldering phenomenon.
Description of drawings
Fig. 1 is the utility model circuit block diagram;
Fig. 2 is the utility model circuit theory diagrams;
Fig. 3 is the schematic diagram that the utility model receives gauge tap amount signal.
Embodiment
Referring to Fig. 1, power supply is connected with the PLC controller, and this PLC controller is connected with signal lamp, hummer, sits the some single-chip microcomputer and is connected with the PLC controller.
Referring to Fig. 2, Fig. 3, external 220V power supply carries out among switching regulator stabilized voltage supply and the PLC, after stabilized voltage supply even changes into 24V, to PLC input, output terminal power supply, the input switch amount of PLC connects the input selector switch amount of relay K N1, KN2, KN3, the PLC output terminal connects two pairs of normally-open normally-closes and succeeds electrical equipment KA1, KA2, KA3, and lamp LTA is connected with hummer FB with KA2, KA3 control, PLC output switching value; Sit some single-chip microcomputer operation part and control PLC input switch amount by receiving key amount relay K A4, the output control relay KA1 of PLC controls and sits the operation of some single-chip microcomputer.
Principle of work is to adopt seat means of spot welds air valve to do the signal source, and receiving key amount relay K A4 comes to do counting usefulness to the PLC controller, through input signal, select KN1,2,3,4 to select number of welds, weld after the affirmation, when reaching the counting of selection, hummer FB reports to the police, disconnect seat point input signal by relay K A1, seat point can not be moved, confirm whether leak source of workpiece then, if there is not leak source, SA1 resets by input signal, carries out next working cycle.Wherein, KA2, KA3 only use as operation and alarm lamp.
Claims (1)
1. the weldering error correction device is leaked in a spot welding, and it is characterized in that: power supply is connected with the PLC controller, and this PLC controller is connected with signal lamp, hummer, sits the some single-chip microcomputer and is connected with the PLC controller.
