Abstract

The utility model discloses a solder skip prevention electric control device for a welding machine, which comprises a power switch, a circuit breaker, an insulating transformer, a noise filter, a key switch, an electric control box, a programmable controller, a wire groove, a terminal plate, an alarm lamp and a photoelectric detection switch. The photoelectric detection switch detects the existence of a workpiece and sends a detection signal to the programmable controller; a holding counter inside the programmable controller processes an external signal; the workpiece is fastened by a clamp during the welding, the holding counter counts the welding times; after the assigned N times of welding are completed, a welding completion signal appears inside the device and the holding counter is cleared to zero at the same time; and if the workpiece is removed after at least once but less than N times of welding is completed, the alarm lamp is turned on and gives a warning sound. The only way of resetting the alarm is to put the workpiece with solder skip in the proper position and then reset the alarm by means of a special key. By recording the welding times of each workpiece, the solder skip of workpiece is avoided. The solder skip prevention electric control device has the advantages of simple structure, low manufacturing cost, convenience for the connection with welding equipment, and reliability of solder skip prevention.

Description

Welding machine seal weld electric control gear

Technical field

The utility model belongs to technical field of electricity, relates to a kind of electric control gear, and particularly a kind of welding machine seal weld electric control gear is applicable to and hangs resistance welder and the control of stud welding machine seal weld.

Background technology

Quality is the basic of Business survival, at present each enterprise all with product quality as the important step in the business administration.For manufacturing enterprise, the completeness of field apparatus and quality control ability also are piths that guarantees product quality.In manufacturing industry, hanging resistance welder and stud welding machine uses very general, and suspension resistance welder in the market and stud welding machine do not have the seal weld function, though there are control devices such as quality testing the production scene, but the people is the product that causes leaks weldering unavoidably, product often occurs and leaks the weldering solder joint or leak weldering double-screw bolt phenomenon.In a single day such product flows in client's hand, will be subjected to client's complaint and claim, simultaneously corporate reputation is caused harmful effect.

Summary of the invention

The utility model discloses a kind of welding machine seal weld electric control gear, leaks the weldering problem to solve existing welding machine workpiece.

The utility model welding machine seal weld electric control gear, comprise power switch, electric cabinet, alarm lamp, it is characterized in that also comprising breaker, isolating transformer, noise filter, key switch, programmable controller, wire casing and terminal board, photoelectric detection switch; Programmable controller contains the maintenance counter.

Power switch, key switch and alarm lamp are installed in the electric cabinet outside; Breaker, isolating transformer, noise filter, programmable controller, wire casing and terminal board are installed in electric cabinet inside; External and the alignment pieces of photoelectric detection switch.

Power switch is used to open and close power supply, starts power switch and introduces the 380V alternating voltage, and the breaker that flows through year protective effect that electrifies is connected between power switch and the isolating transformer; Isolating transformer is the 220V voltage that programmable controller and alarm lamp use with the 380V voltage transitions, and isolates and disturb; Isolating transformer is connected with noise filter; Noise filter will filter out from the high frequency noise in the 220V voltage of transformer, prevents that it from causing damage to programmable controller;

Programmable controller is the core control part of this device, by handling the external signal that receives to its programming, programmable controller has two terminals to be connected to the output of noise filter, have at least three input terminals and an input signal common port on the programmable controller, wherein first input end connects photoelectric detection switch, second input terminal connects key switch, the 3rd input terminal connects the welding of welding machine and finishes signal terminal, at least one output that has on the programmable controller connects alarm lamp, and link to each other with the 220V power supply of isolating transformer output, be the alarm lamp power supply with the 220V power supply of isolating transformer output.

Photoelectric detection switch is this Device Testing parts, and photoelectric detection switch has or not workpiece and detects, and sends signal to programmable controller.

Alarm lamp is the execution unit of this device, and alarm lamp not only can send the light of rotation and report to the police when reporting to the police appears in equipment, and can send loud alarm sound, makes the people in the certain limit all produce vigilance.

The utility model operation principle is as follows: the operator is placed on workpiece when welding on the anchor clamps, maintenance counter in the control device is counted welding times, if it is inferior to have finished the welding times " N " of regulation, can occur welding in the device and finish signal, will keep counter O reset simultaneously; If finished at least once welding, but do not finish when welding for N time, the operator just takes workpiece away, and the alarm lamp of this timed unit can light, and can send loud alarm sound simultaneously.

Because the maintenance counting appliance in the control device has dead electricity to keep function, can not be even the operator opens power-off again with ann reset, with the unique method of ann reset is that the workpiece that will leak weldering places on anchor clamps again, and finds the related personnel who holds the ann reset key to use the private key could be with ann reset.Behind the ann reset, the operator has only and just is unlikely to produce and reports to the police leaking the solder joint or the double-screw bolt polishing of weldering and taking workpiece away.

Finish the welding of weldment Lou as the operator after, can proceed the welding of new workpiece.

Welding times when the operator is welded each workpiece writes down and prevents the Lou generation of welder's part.

The utility model can prevent Lou welder's part with hanging resistance welder or the supporting use of stud welding machine.Have only a terminal with the connection of welding machine, connect simple, supporting very easy to use with welding machine.

Good effect of the present utility model is simple in structure, and cost is low, connects easily with welding equipment, realizes seal weld by software and hardware combining.When the operator will be leaked the workpiece of weldering when taking away, reporting to the police appears in equipment immediately, and the new last workpiece of operator also can't be finished the welding to new workpiece, even operator's powered-down is also of no avail, must find maintenance personal and operator to find Lou welder's part together, after using private key with ann reset simultaneously, could carry out repair welding to leaking welder's part, taking workpiece after will leaking weldering solder joint or double-screw bolt polishing away just can not occur reporting to the police, thereby guaranteed product quality to greatest extent, can prevent Lou welder's part effectively.
