Technical Field
The utility model relates to a vacuum coating processing technology field especially relates to a coating film tungsten filament heater for evaporation.
Background
The evaporation source is resistance heating evaporation source, which is used to melt the film material to evaporate by the resistance heat generated after the heating element is electrified. The heating material is an evaporation source which is made of refractory metal tungsten wires and has a proper shape. Common evaporation sources for evaporation aluminizing are a spiral tungsten wire and a double-peak tungsten wire, wherein the spiral tungsten wire is used for evaporating an aluminum wire or an aluminum sheet, and the double-peak tungsten wire is used for evaporating an aluminum ring or the aluminum sheet. When the aluminum is plated through evaporation, a proper tungsten wire is selected according to the film material.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a can satisfy the evaporation of aluminum sheet, aluminium circle, aluminium silk simultaneously, the utility model provides an evaporation coating film tungsten filament heater, including connecting portion and evaporation portion, evaporation portion includes a plurality of mountain peak sections and spiral section, and is a plurality of mountain peak section sets up spiral section top, mountain peak section with the spiral section is end to end in proper order, connecting portion set up evaporation portion both ends.
Preferably, the interval L2 between the peaks of two adjacent peak sections is 7-10 mm.
Furthermore, the size of the crest section is gradually increased from the top to the bottom in the length direction and the width direction, and the arc transition is formed at the connection part of the crest section and the spiral section.
Preferably, the top of the projection of the mountain peak section in the length direction is semicircular, the outer diameter d1 of the mountain peak section is 4-4.5 mm, the projection of the spiral section in the length direction is arc-shaped, the inner diameter d2 of the spiral section is 6-8 mm, and the vertical distance h between the highest point of the mountain peak section and the lowest point of the spiral section is 15-20 mm. The crest section is used for installing aluminium circle or aluminum sheet, overlaps aluminium circle or aluminum sheet at the top of crest section, because in crest section from the top to the bottom at length direction and width direction size grow gradually, supports the tungsten filament below aluminium circle or the aluminum sheet for can't fall, the spiral section is used for installing the aluminium filament, passes the spiral section installation with the aluminium filament.
Further, for convenient installation, the total length L of the tungsten wire heater is 70-110 mm, and the length L1 of the connecting part of the tungsten wire heater is 20-25 mm.
Preferably, the connecting portion has a straight shape or an L-shape to satisfy different installation methods.
Has the advantages that: the tungsten filament in the utility model can be used for the evaporation of aluminum filament, aluminum sheet or aluminum ring, and the tungsten filament does not need to be replaced when the evaporation material is replaced in the production process.

Detailed Description
As shown in the figure, the evaporation coating tungsten filament heater comprises a connecting portion 3 and an evaporation portion, wherein the evaporation portion comprises a plurality of peak sections 1 and spiral sections 2, the peak sections 1 are arranged above the spiral sections 2, the peak sections 1 and the spiral sections 2 are sequentially connected end to end, and the connecting portion 3 is arranged at two ends of the evaporation portion. The interval between the highest points of two adjacent crest sections 1 is 7-10 mm.
The size of the peak section 1 is gradually increased from the top to the bottom in the length direction (the total length direction of the tungsten wire heater, shown as L in the figure) and the width direction (the total width direction of the tungsten wire heater, shown as M in the figure), and the connection part of the peak section 1 and the spiral section 2 is in arc transition. The top of the projection of the mountain peak section 1 in the length direction is in a semicircular shape, the outer diameter d1 of the mountain peak section is 4-4.5 mm, the projection of the spiral section 2 in the length direction is in an arc shape, the inner diameter d2 of the spiral section is 6-8 mm, and the vertical distance h between the highest point of the mountain peak section 1 and the lowest point of the spiral section 2 is 15-20 mm. The total length L of the tungsten wire heater is 70-110 mm, and the length L1 of the connecting part 3 of the tungsten wire heater is 20-25 mm. The connecting part 3 is in a straight shape or an L shape.
The specific working principle is as follows: the tungsten filament heater connecting part 3 is inserted into the hole of the electrode rod 4, and the electrode rod 4 clamps the connecting part 3. The mountain peak section 1 can be used for installing the aluminum ring 5 or the aluminum sheet 7, the aluminum ring 5 or the aluminum sheet 7 is sleeved on the top of the mountain peak section 1, and because the size of the mountain peak section 1 is gradually increased from the top to the bottom in the length direction and the width direction, the lower surface of the aluminum ring 5 or the aluminum sheet 7 is propped against the tungsten wire heater, so that the tungsten wire heater cannot fall off; if an aluminum wire 6 is used for coating, the aluminum wire 6 can be inserted into the spiral section 2, and the installation schematic diagram is shown in fig. 2.
