[innovation and creation content]
Meet sb. at the airport and do not have the dipulse function in order to overcome existing resistance capacitance stored energy welding; output accuracy is not high; the shortcoming that protective device is few; the utility model provides a kind of resistance capacitance energy storage type bonding machine; this resistance capacitance energy storage type bonding machine is the output accuracy height not only; have multiple protector, and have the dipulse function.
The technological innovation scheme that its technical problem that solves the utility model adopts is: all control all is to be controlled by formula by microcomputer CPU.The conversion of charge and discharge switch by after accepting external command, is called the formula of holder EPROM by microcomputer CPU, sends control instruction after the processing and makes the charge and discharge switch conversion, and control output can accuracy of measurement can reach 0.1%.This formula has been write and can independently have been stored 8 bond pads parameters, and every bond pads parameter is by pulse 1, pulse 2, and dipulse is formed.Dipulse is meant: during discharge, ignition switch triggers once, and is intact when first pulsed discharge, under microcomputer CPU control instruction, postpones to put second pulse more continuously about 200ms, forms dipulse output.Dipulse output is adapted to coated parts welding especially.
The Circuits System design has charge circuit, discharge loop, charge protection device circuit, discharge protector circuit and igniting latching circuit.
Corresponding charge circuit, discharge loop and multiple have been increased from being dynamically connected protective device.Charge circuit has one group of capacitance group to connect charge and discharge switch, control circuit board and power supply input transformer, constitutes charge circuit; Discharge loop connects charge and discharge switch, pulse output transformer, welding work pieces and control circuit board by capacitance group and constitutes discharge loop.The capacitance group of charge protection device circuit is connected with two high-power resistances.Charging process, igniting latching circuit device can not accepted the ignition switch short-circuit signal, guarantees that charge and discharge does not take place simultaneously.Discharge process, discharge self-lock protection circuit arrangement can be forbidden all ignition switch triggering signal inputs, guarantees that discharge and charging do not take place simultaneously.
The open circuit protection switch is connected with the charge circuit of capacitance group, constitutes the breaker protection circuit arrangement.If input voltage is too high, surpass 15% of normal input voltage 220V, the open circuit protection switch trips immediately, disconnects the input power supply.High-power resistance is connected with the charge circuit of capacitance group, constitutes charge protection device.During charging, if voltage amplifier circuit is made mistakes or input voltage when overvoltage occurring, high-power protective resistance just makes capacitance group be discharged to minimum of a value from being dynamically connected, and protection electric capacity is avoided damaging.Discharge resistance is connected with discharge loop, constitutes the power-off protecting circuit device.If outage suddenly, discharge resistance can be dynamically connected certainly.Make capacitance group be discharged to minimum of a value, improve security performance.
The beneficial effects of the utility model are to trigger once discharge output dipulse, multiple protector improving safety, assurance welding quality in ignition switch.
