Description
Technical field
The present invention relates to the electric welding equipment technical field.
Background technology
Known electric welding machine principle is to adopt rectifier transformer system output direct current, produces high temperature by both positive and negative polarity in the bond pad locations short circuit during electric welding operation, thereby realizes welding, this electric welding machine volume is large, heavy, mobile inconvenient, must have in the situation of external power source and could use; The known electric welding machine principle that need not external power source is to adopt the generating set generating, and then rectification is direct current, and this electric welding machine volume is large, and weight is large, and is mobile inconvenient, needs fuel filling.
Above-mentioned two kinds of electric welding machines all can't be realized the manpower transport, and are inconvenient in power free outdoor district work.
Summary of the invention
The technical issues that need to address of the present invention just are to provide a kind of Portable energy-storing miniature welding machine, the invention solves existing electric welding machine and can't realize the manpower transport, in the inconvenient problem of power free outdoor district work.
For addressing the above problem, the present invention adopts following technical scheme: the lithium ion battery group 1, battery protection circuit 2-1 and the charging circuit board 2-2 that comprise housing 5 and be installed in housing 5 inside; Lithium ion battery group 1 is made of several lithium ion batteries 1-1 series connection, reaches the required voltage of electric welding machine after the lithium ion battery 1-1 series connection; The both positive and negative polarity of lithium ion battery group 1 connects battery protection circuit 2-1, battery protection circuit 2-1 and connects charging circuit board 2-2; Also have charging inlet 3 and discharge interface 4 on the housing 5, charging inlet 3 connects charging circuit board 2-2, and discharge interface 4 connects battery protection circuit 2-1.
The present invention overcomes existing electric welding machine and can not portablely operate, and can not be in many defectives of non-transformer environment use.It adopts power type battery to make battery modules; especially adopt lithium ion battery; make the voltage of battery modules identical with electric welding machine voltage; combo forms the current requirements that reaches electric welding; form the normal power of Portable energy-storage electric welding machine; battery protecting circuit and charging circuit are installed simultaneously, are consisted of whole electric welding machine system.Whole Portable electric welder is lightweight, and volume is little, can reach manpower and carry, and can be widely used in the outdoor emergency operation and use.
Description of drawings
Fig. 1 is structural representation of the present invention.
Symbol description among the figure: lithium ion battery group 1, lithium ion battery 1-1, battery protection circuit 2-1, charging circuit board 2-2, charging inlet 3, discharge interface 4, housing 5.
The specific embodiment
As shown in Figure 1, Portable energy-storing miniature welding machine, the lithium ion battery group 1, battery protection circuit 2-1 and the charging circuit board 2-2 that comprise housing 5 and be installed in housing 5 inside; Lithium ion battery group 1 is made of several lithium ion batteries 1-1 series connection, reaches the required voltage of electric welding machine after the lithium ion battery 1-1 series connection; The both positive and negative polarity of lithium ion battery group 1 connects battery protection circuit 2-1, battery protection circuit 2-1 and connects charging circuit board 2-2; Also have charging inlet 3 and discharge interface 4 on the housing 5, charging inlet 3 connects charging circuit board 2-2, and discharge interface 4 connects battery protection circuit 2-1.
The technical solution adopted for the present invention to solve the technical problems is: adopt the power-type lithium ion battery to be connected into the electric welding machine required voltage, the power-type capacity of lithium ion battery, can be for satisfying the needs of electric welding electric current when the multiplying power discharging that battery allows, can make the battery long-life like this, satisfy simultaneously the little lightweight minimum requirements of capacity.Between the both positive and negative polarity of battery, add battery protecting circuit, do not put so that battery can not be crossed, thus the protection battery.Battery protecting circuit is overcharged and crosses at battery system can disconnect major loop when putting, thus the protection battery; External charger is adopted in charging, and charging voltage satisfies the battery system needs, and charger can adopt current-limiting apparatus, carries out work in the floating charge process to satisfy.
When discharge, discharge interface 4 external discharging currents; When charging, charging inlet 3 access external communication civil power inputs can be charged to lithium ion battery; The input of interchange is externally arranged; and when the output of interchange is arranged simultaneously; regardless of discharge power and charge power; the power of lithium battery and outside input power sum are the power output sum; the input of lithium ion battery group 1, power output can be just also can be negative, by the control of battery protecting circuit and charging circuit.
The invention has the beneficial effects as follows: 1, volume is little lightweight, is suitable for portable; 2, adopt holding circuit, guarantee the long-life of battery; 3, can emergency in the occasion that does not have power supply; 4, can adopt easily civil power to replenish.
Described battery protecting circuit can adopt the battery protecting circuit of prior art, and this circuit can be multistage, and a protector can be by spark gap, and piezo-resistance and semiconductor form.Sometimes needing between level and level can be flux matched to reach with decoupling component.What the present invention adopted is lithium battery protection circuit; formed by two FETs and privacy protection integrated package S--8232; overcharge control valve FET2 and overdischarge control valve FET1 is series at circuit; by protecting IC to monitor cell voltage and controlling; when cell voltage rises to 4.2V; additives for overcharge protection pipe FET2 cut-off stops charging.For preventing misoperation, generally be added with delay capacitor at external circuit.When battery is under the discharge condition, when cell voltage was down to 2.55V, overdischarge control valve FET1 cut-off stopped to power to the load.Overcurrent protection is when having larger electric current to flow through when load, and control FET1 makes its cut-off, stops to load discharge, and purpose is in order to protect battery and FET.
Described charging circuit can adopt the lithium ion cell charging circuit of prior art, and its principle is: adopt constant voltage to charge the battery, guarantee can not overcharge.
It should be noted that at last: obviously, above-described embodiment only is for example of the present invention clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among protection scope of the present invention.
