Original technology adopts ultrasonic bonding to finish the continuous welding of positive plate white space and flow collection band.Fundamentals of Welding: supersonic generator acts on transducer with power, the vibration of transducer obtains mechanical activation amplitude by amplifier and amplifies, and passing to soldering tip, strong ultrasonic vibration power is added on the welded article under the pressure at right angle effect, makes two intermetallics produce the high frequency sassafras that rubs.The acting in conjunction of ultrasonic vibration power and pressure at right angle makes this be spread mutually by metallic atom in the welding zone territory, or mutually near carrying out solid state bonded under the state, thereby make the two metal faces of weld form real alloy interface.Ultrasonic bonding compare with resistance welded have not yielding, solder joint firmly, the welding internal resistance is little, do not produce oxide layer, advantage such as quick, energy-conservation.Supersonic welder comprises in original technology: the welding machine main body, initiatively weld parts such as wheel, welded rails, driven weldering wheel, driven weldering wheel support, total support, welding machine main body holder, cylinder.The main body of supersonic welder (initiatively weldering wheel) is installed in the welded rails top, supporting the weldering wheel is that driven pulley is installed in the welded rails below, initiatively, driven two weldering wheels are Surface Machining go out the to gather alloy wheel of rhombus reticulate pattern, the decorative pattern dispersion of distribution designs according to the width of welding region.The problem that exists:
1, welds after pasting owing to the metal flow collection band, original machine structure is placed on the weld interface top with the welding machine main body, under the high-frequency mechanical vibration effect that initiatively weldering is taken turns, pole plate will inevitably produce the powder phenomenon, dust is deposited on the weld interface of white space and flow collection band formation, make to occur being mingled with in the welding process, have a strong impact on welding quality.
2, original driving and driven weldering wheel surface is identical shaped network decorative pattern, and frictional force is little, and the welding contact-making surface is big, energy disperses, occur skidding easily at the pole plate direction of travel and cause the discontinuous of welding, leak the phenomenon of weldering and base material fracture, increase the internal resistance of cell.
Summary of the invention
The purpose of this utility model provides and a kind ofly can effectively improve welding quality, welding effect, satisfy the technological requirement of positive plate flow collection band continuous welding, lower the internal resistance of cell, improve the positive plate flow collection band supersonic welder of the high rate during charging-discharging of power-type Ni-H battery.
Technical solution: the utility model positive plate flow collection band supersonic welder, comprise: total support, welding machine main body, welding machine main body holder, initiatively weld wheel, cylinder, driven weldering wheel support, driven weldering wheel, welded rails, initiatively the weldering wheel is arranged at the welded rails below, and driven weldering wheel is arranged at the welded rails top.
Driven weldering wheel outer surface middle part is provided with the donut decorative pattern, and top and bottom between the adjacent two donut decorative patterns respectively are provided with circular protrusions.
The utility model initiatively weldering wheel moves to the welded rails below, driven weldering wheel moves to the welded rails top, the compressed air active force is made progress by changing into downwards, high frequency acts mechanically on the pole plate below, the dust that produces directly falls into gatherer, has solved the problem that former design welding position dust is piled up influences welding quality; Change the surface detail shape that supports the weldering wheel, change present donut shape into by original network, top and bottom between adjacent two donuts respectively are provided with a circular protrusions.This weldering wheel construction can increase the frictional force of weld interface, and the welding of realization continuity can reduce the welding contact area simultaneously, makes energy accumulate in the annulus jut, improves weld strength, solves the problem of skidding of welding; For the overall performance of Ni-MH power cell, improved the conductivity of positive plate, effectively reduced the internal resistance of battery.
