The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
As Figure 1-3, the seal weld control circuit that the present invention includes power circuit, is electrically connected to power circuit and the mash welder control loop being electrically connected to seal weld control circuit, described seal weld control circuit comprises can gather welding signal and the welding of the needs counting device that compares and in parallel with counting device for showing the alarm device whether having welded of counting.
As shown in Figure 1, power circuit is comprised of power module T1 and the air switch QF that High Level AC Voltage can be converted to low-voltage DC, air switch QF is connected to one end that power module T1 is electrically connected to high-voltage alternating, and power module T1 is for can become AC220V the transformer of DC24V.
As shown in Figure 2, seal weld control circuit is comprised of the first break-make knob SA1, the second break-make knob SA2, the 3rd break-make knob SA3, counter JS, counter normally opened contact JS-1, relay coil KA1, relay normally open contact KA1-1, polyphony electronic alarm FMD and rotation indicator lamp HL1; By power circuit, exported+24V power supply after break-make knob SA1, draw San Ge branch and be connected with SR SB1, counter normally opened contact JS-1, relay normally open contact KA1-1 respectively; Wherein SR SB1 accesses 0V ground connection common port after connecting with counter JS, and the present invention be take YF-0201Z5 resistance welding controller as example, welding end signal lead-out terminal 33,34 access counter JS; Access 0V ground connection common port after counter normally opened contact JS-1 connects with relay coil KA1; Access 0V common port after relay normally open contact KA1-1 connects with the second break-make knob SA2, polyphony electronic alarm FMD; Access 0V ground connection common port after relay normally open contact KA1-1 connects with the 3rd break-make knob SA3, rotation indicator lamp HL1.
As shown in Figure 3, mash welder control loop comprises two signal input terminals 14,15 for being connected with mash welder, contact KA and relay normally-closed contact KA1-2 are controlled in the welding that is provided with series connection between two signal input terminals 14,15, mash welder control loop is being in the original control loop of mash welder, to increase a relay normally-closed contact, is used for preventing many welderings.
During work, first closed air switch QF, and the first break-make knob SA1, the second break-make knob SA2, the 3rd break-make knob SA3 are got to on-position, and then a required welding of the workpiece M(that counts is set on counter scope 0-9999999 is set), can start welding.
Counter JS in the present invention, only at solder joint, there is electric current to pass through time side's counting, counting not during empty weldering, when M is counted in the technique welding that the welding signal N gathering from welding end signal lead-out terminal 33,34 when counter equals to set (N=M), the normally opened contact JS-1 of counter JS is closed, and relay coil KA1 is charged, relay normally open contact KA1-1 is closed, now occur sound and light alarm, prompting welding ends, and realizes normal welding function; If continue welding after N=M, i.e. it is closed that contact KA is controlled in mash welder welding, and now because relay coil KA1 is charged, relay normally-closed contact KA1-2 disconnects, and occurs the motionless phenomenon of equipment, realizes and prevent many weldering functions; If during N < M, this hour counter normally opened contact JS-1 does not have closure, there is no sound and light alarm, requires to continue welding, realizes seal weld function.After there is sound and light alarm, while being N=M, press SR SB1, the welding points N zero clearing that counter JS receives, counter normally opened contact JS-1 disconnects, relay coil KA1 dead electricity, relay normally open contact KA1-1 disconnects, sound and light alarm disappears, and relay normally-closed contact KA1-2 is closed, and mash welder can continue welding.Because of before the welding that the arranges M that counts be still stored in counter (this counter has power failure memory function, the M that counts is set and can lose), enter next round circulation, workflow diagram as shown in Figure 4.
The first break-make knob SA1 in the present invention, when debugging part, rotates to disconnected position, and seal weld device is inoperative, convenient debugging; The second break-make knob SA2 and the 3rd break-make knob SA3 can need to only connect one of them according to site environment,, only with polyphony electronic alarm or rotation indicator lamp, also can two connections simultaneously use simultaneously.Wherein polyphony electronic alarm has five kinds of sound, and volume can regulate arbitrarily between 0～95dB; Rotation indicator lamp contains permanent magnetism base, can exempt from an arbitrary position to install and place.
The content not being described in detail in this description belongs to the known prior art of professional and technical personnel in the field.
