Detailed description of the invention
Fig. 1 is that the application includes air knife in interior schematic perspective view.
Fig. 2 is the application air knife structure side view, including gas source module schematic diagram.
Fig. 3 is the three-dimensional another view stereo structural schematic diagram of the application.
Specific embodiment
Referring to figs. 1 to shown in Fig. 3, PCB sprays tin and post-processes cooling system 200, including gas source 100 and connects with gas source 110
The air knife 100 connect；The air knife 100 includes being mounted on 107 upper air knife cutter head 118 of air knife bracket, and the air knife cutter head 118 can be
It is rotated on air knife bracket 107, air knife cutter head 118；The air knife includes the first air hose 102 and the second air hose 106, first wind
Pipe 102 and the second air hose 106 are connect with the central siphon 114 being plugged in the bracket 107, and the central siphon 114 passes through the air knife
Bracket 107 is simultaneously rotationally connect with air supply pipe.
The gas source 110 is high-pressure air source system, and high-pressure air source system includes the pressurization air pump 122 of air accumulator 121 and control
System 124, the control system 124 maintains the air pressure in air accumulator 121 on one specific threshold value, and the threshold value
It can adjust in a certain range.
For air knife 100 for connecting gas source 110 and controllable ejection pressure-air, air knife cutter head 118 prolongs Shen including first
Pipe 105, the Shen pipe 105 that prolongs is hollow tube, is gradually narrowed in the one side edge of extension 105, the overall structure of Yan Shenguan is
Wedge shape, is the air outlet 119 of air knife in the end of wedge structure, it is advantageous for the air outlet 119 generally narrow slit structure
In the wind speed for improving air outlet.
When air knife 100 works, air knife can rotate on the air knife bracket 107, the wind that air knife sprays during rotation
Direction also change during rotation therewith.
Air knife further includes the first air hose and the second air hose, and the first air hose and the second air hose have symmetrical structure, exist in this way
The first air hose 102 and the second air hose 104 have the good performance of dynamic balancing in air knife rotation process.The two is in addition to that can be the wind
The connection medium of air knife cutter head 118 Yu central siphon 114 is also used as other than the gas supply of knife cutter head 118.
In the present solution, the air knife cutter head 118 can rotate during spraying wind, and when driving the direction for spraying wind
Quarter changes, and the wind direction of change can be to the PCB version borehole handled by fixed wind direction air knife not, the spray tin burr on dead angle
With good effect, so that the spray sheet tin surface Glabrous after cooling treatment assassinates angle.
The air knife includes power part, for driving the air knife cutter head 118 and central siphon 114 to rotate, is moved in this application
Power portion can with when all those skilled in the art that air knife cutter head 118 can be driven to rotate such as external motor, mechanical structure it is public
The technical solution known all can be used as its power part.The power part driving air knife is rotated by middle line of central siphon, the air knife bracket
Central siphon bearing 115 is provided on 107, the bearing 115 is used to support central siphon 114, and the power part drive shaft tube makes central siphon
114 are freely rotated on bearing 115.
In the preferred power part scheme, the application provides relatively simple power part structure, the power part packet
It includes and prolongs the air outlet 103 with switch being arranged on Shen pipe 105 in air knife cutter head 118, which opens space-time
Gas blowout, which goes out, drives the air knife cutter head 118 to rotate.
The power part air outlet 103,104 include it is multiple be arranged in the prolonging on Shen pipe 105 of the air knife, it is each it is described go out
The direction in air port 103,104 is vertical with the direction of air knife jet, in this way due to the jet active force of air outlet, the air knife knife
First 118 can rotate at work.The speed of air knife rotation can determine that air knife is rotated by the quantity of the air outlet 103
Direction can be determined by the position of air outlet 103,104.The air knife when opening one or more air outlets 104 on right side
It rotates counterclockwise, when opening left side one or more air outlet 103, the air knife turns along clockwise direction
It is dynamic.
The scheme of the air outlet 103 can also be replaced by changing the air-out direction of air knife, specifically be air knife one end
Air outlet 119 fraction direction deflection 30 to 90 degree, such air-flow can generate one with the air knife cutter head 118 prolong Shen
The vertical thrust in direction is to push the air knife to rotate along the central siphon.
Side of the central siphon 114 far from air knife is connect with gas source end pipe 116, and the gas source end pipe 116 connects with gas source 110
Connect, the central siphon 116 connect with gas source end pipe can seal gas can mutually be freely rotated again.
In order to enable more firm, the setting fixed frame 108 in the end pipe 116 that end pipe 116 is fixed, the fixed frame 108 use
In being connected and fixed the end pipe 116 with air knife bracket 107, fixed bracket 108 passes through connecting rod 131 and the air knife bracket 107
It is fixed.There is the axis hole for supporting the end pipe inside one end that the fixed bracket is connect with end pipe.
There is the fixed air knife position of fixed interface, the air knife can be fixed by fixed interface on the air knife bracket
On bracket, wall, mechanical equipment, the fixed interface includes but is not limited to the conventional fixing means such as screw rod, nut, pin.
