Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of electric welding machine solder joint counter-controller is made of casing 1 and the control circuit that is installed in the casing.Casing is provided with control panel 2 and on ﹠ off switch 7.Its innovative point is: control circuit is made of single-chip microcomputer, storer, keyboard display chip, current sensor, amplifier, relay.Single-chip microcomputer by the I/O interface respectively with the keyboard display chip, storer, relay and amplifier are connected.
The keyboard display chip is connected in keyboard 4 on the casing control panel by data line, can adopt keyboard that data such as welding sampling time, off time, solder joint upper limit number, solder joint lower limit number are set.The keyboard display chip is connected in light-emitting diode display 3 on the casing control panel by data line, light-emitting diode display is made of four eight sections LED of four rows, and the scanning of being finished four row's group of four figures pipes in conjunction with two 74HC164 shift registers by the keyboard display chip shows.In welding process, light-emitting diode display shows be welded workpiece counting, pad upper limit number, solder joint real-time counting, pad lower limit number respectively, and when occurring leaking weldering or welding more, pad upper limit number or pad lower limit number constantly glimmer, and are reminded.
Single-chip microcomputer is connected with the current sensor output terminal by the amp.in that the I/O interface connects.The current sensor input end is connected in the current signal input port 8 that is arranged on the casing, is connected with the welding gun current signal line of being drawn by control box, realizes the detection of Butt welding gun current signal, and then realizes the solder joint counting.
Single-chip microcomputer is connected in the control signal output ends mouth 9 that is arranged on the casing by the relay output end that the I/O interface connects, and is connected in control box by control line, thereby realizes the locking of Butt welding gun.Single-chip microcomputer also connects a Puzzle lock 6 that is arranged on the casing control panel by the I/O interface.After controlled welding gun is lockable, could continue welding, force the Welder performer in time to correct the error that occurs in the welding thus by Welder performer key reset count lock.The I/O interface that single-chip microcomputer connects relay connects a hummer 5 that is arranged on the control panel simultaneously, and when leaking weldering or welding more, hummer is reported to the police.
