Technical field

The present invention relates to power-supply device technical field, specially a kind of compact-sized source of welding current.

Background technique

The requirement that the development of new science and technology, new process and new material is substantially increased to welding technique is higher and higher, except requirement Spatter is small, welding process is stable, and except reliable in quality, certain occasions also require light structure, using flexible.

Its optimization of inside structure of the existing source of welding current is inadequate, and being limited by heat extraction, protection circuit, control circuit etc., other are auxiliary The design of structure is helped, it is whole often still not compact enough, it shows slightly clumsy, is such as welded in space, welding robot etc. automates journey Its volume is spent in higher scene with regard to excessive and overweight.

Whether the process of welding is stable often to determine that often power frequency is higher by the frequency of electric current, and output is more steady, The quality of welding is also higher, and the power frequency of existing source of welding current output often make by limited or current switch load difference At local fault, causes electric current in welding process not stable enough, reduce welding quality.

Summary of the invention

For the deficiency of above-mentioned background technique, the present invention provides a kind of compact-sized sources of welding current, and it is tight to have structure It gathers the advantage high with output accuracy, solves the problems, such as background technique proposition.

The invention provides the following technical scheme: a kind of compact-sized source of welding current, including shell, the side of the shell It is equipped with input mirror image, the side of the input mirror image is equipped with charge and discharge mould group, and the side of the charge and discharge mould group is equipped with Control panel, the front end of the control panel are equipped with output board, and the rear end of the control panel is equipped with mainboard, the shell The other end be equipped with control panel, between the charge and discharge mould group and control panel by transmission of electricity plate be electrically connected, and transmit electricity Plate is located at the lower end of charge and discharge mould group and control panel, and one end of the transmission of electricity plate is equipped with Hall coil.

Preferably, the charge and discharge mould group is connect by fin outstanding with shell, and two adjacent charge and discharge mould groups In contrary setting.

Preferably, the Hall coil is caused by four pieces of small-sized circuit boards, and the transmission of electricity plate is from the middle part of Hall coil Pass through, the Hall coil is in the gap between control panel and output board.

Preferably, the bottom of the shell is equipped with air inlet, the position of a part of air inlet and quantity and charge and discharge The quantity of mould group and position are corresponding, and air inlet described in another part is corresponding with the position of control panel, and the charge and discharge mould group is Vertical single design, the exhaust outlet are located at the upper end of shell side.

Preferably, the electric discharge of the charge and discharge mould group is controlled by control switch in parallel, and the control switch is MOS-FET Electronic component.

Preferably, the output board is assemblied on the bottom plate of shell, and the output board is parallel with the side plate of shell, and shell Side plate be equipped with and the matched opening of output board.

The present invention have it is following the utility model has the advantages that

1, the compact-sized source of welding current uses more reasonable component package assembly and assembling morphology, simultaneously Heat dissipation design, control circuit, monitoring circuit design are more compact, have further reduced the size of component, have made overall structure more Step up to gather, improve whole flexibility ratio and reduce quality, improve the application scenarios of the compact source of welding current, it is made to be adapted to energy Power is stronger.

2, the compact-sized source of welding current, control switch use the MOS-FET that switching frequency is up to 2,000,000 HZ Element, control frequency is higher, so that its output accuracy is higher, output electric current is more steady, secondly because the release of electric current is big Small to be determined by the unlatching quantity of control switch and opening time, due to frequency height, the single opening time is shorter, so control switch Quantity it is also relatively more, the load of single control switch is smaller, it is not easy to damage, further, if some control switch send out Raw failure, can then bear excessive abnormal load with control switch remaining in one action, since single time is shorter, be left Control switch bear the abnormal load time it is shorter, more difficult damage, due to internal control switch spoilage it is smaller, into one Step ensure that output accuracy.
