The groove face of boat.Existing aluminium wire vaporising device, evaporation boat be horizontally disposed namely evaporation boat close to positive and negative electrode both sides slot
Face is contour, in addition the contact that aluminium wire reaches evaporation boat groove face is positioned at the middle part of evaporation boat, the aluminium wire evaporation of this structure
Device, it is easy to form accumulation after causing aluminium wire to be melted on evaporation boat, be not easy to scatter, subtract so as to cause aluminum melt disengagement area
Small and evaporation capacity is reduced, and target side leakage easily occurs, and is also easy to produce aluminium specking, and then damage base material film.
Invention content
To overcome the problems, such as present on, the purpose of this utility model is to provide a kind of the thin of simple structure and reasonable design
The aluminium wire vaporising device of film vacuum aluminum-plating equipment.
The aluminium wire vaporising device of equipment in order to achieve the above object, the film vacuum of the utility model is aluminized, including evaporation boat
With the positive and negative electrode at left and right sides of evaporation boat, it is characterised in that：The evaporation boat is the strip that surface has strip groove
Support base made of shape refractory metal or alloy sheet, the positive electrode and negative electricity extremely conductive material, the both ends of evaporation boat
It is fixed on positive and negative electrode support base, groove groove face of the evaporation boat close to negative electrode side is higher than the groove close to positive electrode side
Groove face, so that the entire groove groove face of evaporation boat becomes the inclined-plane horizontal by 4-6 ° of angle, aluminium wire comes out from wire feeding guiding tube
Groove face of the evaporation boat close to cathode side is reached afterwards.
Above-mentioned positive and negative electrode support base is Horizontal cylinder body and axle center carries lateral projections, and branch is fixed at the both ends of evaporation boat
On the lateral projections top surface for supportting seat, the height of positive electrode support base lateral projections top surface is less than negative electrode support base lateral projections top
The height in face.
In order to make aluminium wire melt after have disengagement area as big as possible, the contact of above-mentioned aluminium wire end and evaporation boat groove face
Distance to evaporation boat close to one side end face of cathode is the 1/4-1/3 of evaporation boat length.
The film vacuum of the utility model is aluminized the aluminium wire vaporising device of equipment, by the groove face of evaporation boat groove be designed as with
Horizontal plane is in the inclined-plane of 4-6 ° of angle, and groove face of the evaporation boat close to cathode side is reached after so that aluminium wire is come out from wire feeding guiding tube,
Aluminum melt after aluminium wire can be made to melt slowly flows while evaporating to lower from the eminence of evaporation boat, and the process flowed is not
The disengagement area of aluminum melt is increased only, and reduces the accumulation of aluminum melt so that aluminum melt evaporation is more abundant, and aluminum steam is true
Empty indoor distribution is more uniform, goes out to greatly reduce the phenomenon that generating aluminium-plated point damage base material film because of the accumulation of aluminum melt
It is existing, it also can avoid causing side leakage because the accumulation of aluminum melt is excessive, reduce waste.The aluminium wire vaporising device of the utility model, knot
Structure is simple, reasonable design, aluminizes production for the film vacuum of direct vapour deposition method, is conducive to raising working efficiency and product matter
Amount.
Description of the drawings
Fig. 1 is the structural schematic diagram of the aluminium wire vaporising device of the utility model vacuum aluminum-plating equipment.
Fig. 2 is the structural schematic diagram of the utility model aluminium wire vaporising device evaporation boat.
Specific implementation mode
As shown in Figure 1, 2, the aluminium wire vaporising device of the vacuum aluminum-plating equipment of the utility model, including evaporation boat 1, positive electrode
2 and negative electrode 3；Evaporation boat is that strip refractory metal or alloy sheet, positive and negative electrode of the surface with strip groove 11 are
The support base of lateral projections 21,31 is carried made of conductive material with cylindric and axle center, a left side is fixed at the both ends of evaporation boat
On the top surface of the lateral projections of right positive and negative electrode support base, the height of positive electrode support base lateral projections top surface is less than negative electrode branch
Support the height of seat lateral projections top surface so that groove groove face of the evaporation boat close to negative electrode side is higher than close to positive electrode side
