Abstract

A strong wind knife with high wind speed and concentrated wind power is disclosed, which is particularly applicable to the strong weathering for the wiring board. An air intake is disposed at the middle of the rear of the wind knife where the cross-sectional area is relatively large, thereby homogeneously increasing the air quantity entering into the wind knife. The air-out panel is provided with eyelets whose proportion between the length and the aperture is 4:1. The air outlet is in a two-row style to blow the water droplet remained in the eyelet of the wiring board, wherein one row of water passing ports is aligned in an oblique direction of 15 degrees and the other row is in a perpendicular direction. The strong breeze wind knife has multiple functions such as strong blowing and weathering.

Description

Strong Wind Knife

Ji Intraoperative field

A kind of Strong Wind Knife of the utility model is particularly useful for the air knife that P.C.B. wiring board brute force dries up.

Bei Jing Ji Intraoperative

At present, the air knife that adopts in dry plate machine in P.C.B. equipment producer is kerve tuyere-type or single cellular type, or the brill aperture is an air outlet on the employing sheet metal, the shortcoming of this air outlet is the thin-walled hole for the air-out aperture, and air-flow easily forms vortex and refluxes when passing the thin-walled hole at a high speed, produce whistle, and the distinguished and admirable flow-disturbing that forms at air outlet that the thin-walled aperture comes out is interfered mutually, and flowed energy obtains loss, thereby can not effectively dry up for the water droplet that reaches in the aperture of pcb board face.

Summary of the invention

At the deficiency of above air knife, the utility model is a kind of Strong Wind Knife, and its unique design can make that blast is big, the wind speed height, and can rise the powerful functional effect of catching up with water, drying up one of collection.

Its technical problem that solves the utility model adopts De Ji Intraoperative scheme to be: employing thickness is that 15 millimeters aluminum alloy material wind outlet panel is formed, and the locating hole location is adopted at the blade two ends.Drilling bore hole length reaches 4: 1 aperture with the aperture ratio on wind outlet panel, this structure energy operative constraint aperture inner fluid moulding; Avoid forming flow-disturbing, prevent to produce whistle, reduce and interfere the loss that causes mutually at air outlet.Wind power energy is concentrated, this structure also adopts double pore structure, a round 15 ° of degree that tilt wherein, and another round is vertical, thereby the phase mutual interference that effectively prevents the pencil air-flow makes powerful air-flow form intensive air curtain, reaches the purpose that effectively blows off the small water droplet in pcb board face and the Small Holes.

The beneficial effects of the utility model are: the wind speed height of this air knife, blast is big, and can play and integrate the functional effect that brute force is caught up with water, dried up, prevent to produce whistle and the mutual interference mutually that prevents the pencil air-flow, effectively blow off the small water droplet in pcb board face and the Small Holes.

The specific embodiment

In Fig. 1, blade (2) is a flap on bending machine, takes integral solder to form, and air inlet (1) is welded on the top of the centre of blade (2) one ends, joins by snap joint and the air outlet that is located on the unit.The two ends of blade (2) are provided with locating hole (3), and with screw rod and fuselage location, wind outlet panel (4) goes up bores two discharge wind apertures (5), is directed downwards.

In Fig. 2, double hole is handed over and is arranged arrangements, 15 ° of angles of round inclination wherein, and another round is vertical.

Claims

1. a Strong Wind Knife is made up of the wind outlet panel of aluminum alloy material, and there is locating hole at its feature blade two ends, and there is air inlet the centre, and the air-out aperture is arranged on the wind outlet panel.

2. Strong Wind Knife according to claim 1 it is characterized in that described wind outlet panel is that to adopt thickness be that 15 millimeters aluminium alloy shapes, and drilling bore hole length reaches 4: 1 air-out aperture with the aperture ratio on wind outlet panel.

3. Strong Wind Knife according to claim 1 is characterized in that the air-out aperture on the described wind outlet panel is with certain pore size and the staggered double hole of spacing, and wherein a round is the 15 ° of degree that tilt, and another round is a upright opening.
