Description
Technical field
The utility model relates to a kind of automatic net devices of screen printer.
Background technique
The full name of screen printer is screen process press, it is that solder(ing) paste or Heraeus are bitten on PCB pad by silk screen
A kind of equipment.It is mainly used in electronics processing industry, the silk-screen mark of printed circuit board, the mark of tool housing panel, electricity
Solder(ing) paste printing in the plate process of road etc..
During silk-screen, ink is had below the screen frame of screen printer and is emerged, if do not removed, ink can block mesh,
Blocked mesh can not silk-screen, cause silk-screen that can not carry out, so must in time dispose the ink emerged.Currently, net
The ink that bottom is overflowed is all made of manual wiping form and is handled, i.e., during silk-screen, if quality restriction has found pcb board
Some mesh by silk-screen success, will not check the case where screen frame is blocked either with or without ink on screen printer, according on pcb board
The corresponding web plate position of position detection, then carry out manual wipping movement.Manual wipping needs first shut down screen printer, then by silk
Print machine crossbeam is increased to the position that worker is able to enter, and gets into net bottom by worker, directly wipes to plugging point by non-dust cloth,
This wiping mode was not only time-consuming but also dangerous.When carrying out vacuum screen printing, need first by vacuum chamber opening, then manually wiped
It wipes, since vacuum screen printing needs vacuumize, and the time for vacuumizing cost is longer, and ink removing of progress is caused to need to spend
The a large amount of time has seriously affected the efficiency of production.

The operation for stating lead screw transmission mechanism is synchronous.
Further preferred embodiment is that lifting mechanism is provided on the movable stand, and the lifting mechanism includes the second gas
Cylinder, guide post and movable block, second cylinder are mounted on the movable stand, the movable end of second cylinder and the work
Motion block rigid connection, one end of the guide post are fixed on the movable stand, and the guide post passes through the movable block, the guide post
It is slidably matched with the movable block, the both ends of the bracket cooperate with the movable block of lead screw transmission mechanism described in two groups respectively pacifies
Dress.
By above scheme as it can be seen that guaranteeing that there is bigger activity space in the net mechanism by the way that the lifting mechanism is arranged,
Adapt to different working conditions.
One preferred embodiment is, the dust-free paper includes being successively set on institute along the length direction of the base for receiving mechanism
State guiding axis, drive shaft and the clamping axis of bracket, the dust-free paper further includes stepper motor for receiving mechanism, the stepper motor with
The drive shaft transmission connection, the Wiper plate and first cylinder are between the guiding axis and the drive shaft.
By above scheme as it can be seen that installing dustless paper roll by using roller shaft type, and using the stepper motor with it is described
Dust-free paper after driving axis connection will use recycles, and keeps the efficient work of the net mechanism quick.Dust-free paper is from the clamping
Axis stretches out, and process and the upper surface for covering the Wiper plate are folded down by two guiding axis, passes through from the lower section of the Wiper plate
Cross and with the driving axis connection.
