, height sensor 12 is arranged in 4 lower section of screen frame, for monitoring Printing screen at a distance from aluminium sheet 2 and workbench 7.Further
Nozzle 6 connect insulating cement tank, can continuously, equably, quantitatively export sizing material to Printing screen 3 on.Further spray
Mouth 6 can be by the angle of supervisory control desk controlled level, the movement of vertical direction and nozzle.Scraper mobile bar and nozzle with always
Console connection control.
The aluminum substrate of the utility model is as follows with the operation principle of four-column type full-automatic printer：
The belt pulley of automatic feeding system carries out pretreated aluminium sheet 2 to be delivered to automatic printing system, and workbench 7 is held
After carrying aluminium sheet 2, sliding conductance rail 10 is opened by aluminium sheet 2, is slowly sent to intermediate printing work region, this process keeps slow
Slowly, uniform transmission speed.When aluminium sheet 2 is sent to working region, multiple alignment sensors can supervise the position of aluminium sheet 2
It surveys, it is ensured that aluminium sheet position complete one is in working region, and when can complete printing operation, alignment sensor 11 sends out letter to supervisory control desk
Number, supervisory control desk control automatic lifting column 8 starts to start, and heads on the uniformly movement upwards of workbench 7, close to Printing screen 3.
Not up to before designated position, scraper 5 and not in contact with Printing screen 3, Printing screen 3 is horizontal, undeformed, tension-free shape
State.

Clearance height H between aluminium sheet 2, after clearance height H reaches preset value, automatic lifting column 8 stops lifting.
Nozzle 6 is started to work, while horizontal direction moves, start to Printing screen 3 equably, quantitative ejection insulation
Glue.After spray volume reaches scheduled value, scraper mobile bar 13 starts, and swivel head 14 rotates, and the water with advance is arranged in scraper 5
Square at an angle to tilting, then scraper mobile bar 13 moves down, and presses to Printing screen 3, web plate 3 contacts with aluminium sheet
Afterwards, translation to the left or to the right, starts printing work.According to preset program, scraper 5 after a direction completes one-step print,
14 direction of rotation of swivel head the angle mirror face turning of scraper 5 is completed into subsequent printings in the opposite direction.It is left in printing process
Nozzle (when scraper is tilted to the left, left nozzle follows) or right nozzle remain and scraper a certain distance, synchronizing moving.
After printing several times back and forth, insulating cement is printed to surface of aluminum plate, 5 upward withdrawing of scraper returns to initial position, nozzle also returns
To initial position.So far, printing work terminates.
When determining that plating last layer is uniform, consistent heat conductive insulating glue-line on aluminium sheet 2, automatic lifting column 8 starts to decline,
The horizontal position with height such as the conveyer belts on the right is dropped to, stops declining.At this point, the sliding conductance rail 10 on workbench 7 opens
It is dynamic, the aluminium sheet printed is delivered to discharge system.
Start to start after discharge system carrying aluminium sheet, starts to export the aluminium sheet printed.Preferably, at discharge system end
End installation vacuum hotpressing solidification equipment, the aluminium sheet printed is cured, compression moulding.
So far, the printing work flow of complete set is completed.
Using the utility model full-automatic printer prepare heat conductive insulating glue-line is uniform, ingredient is consistent and automation journey
Sequence is high, has the function of automatic charging, automatic positioning calibration, automatic printing, self-emptying etc..
