The specific embodiment

Below in conjunction with accompanying drawing and preferred forms the utility model is done further detailed description:

As Fig. 1～shown in Figure 4, manufacture and design a kind of vision printer that comprises many cleaning devices, described printing machine comprises steel mesh 10, first cleaning device 21, there is print system 400 top of described steel mesh 10, print system 400 has scraper 401, the below of steel mesh 10 has optics alignment system 300, PCB circuit board to carry the clamping system 500 and first cleaning device 21, and first Printing Zone 11 is arranged on the steel mesh 10; Especially, described printing machine also comprises:

One second cleaning device 22 also is arranged on the below of steel mesh 10;

One steel mesh driver 101 connects and drives steel mesh 10 and moves, and described steel mesh driver 101 connects computer master control system 200;

Set up second Printing Zone 12 on steel mesh 10, described second Printing Zone 12 is identical with first Printing Zone, 11 contents.

In the said mechanism, in preferred forms, described second cleaning device 22, first cleaning device 21 are divided into the both sides of PCB circuit board 30 positions, also first cleaning device 21 and second cleaning device 22 mode by other can be provided with, but the cost of other method to set up can be higher than preferred forms.

As shown in Figure 1 and Figure 2, second Printing Zone 12 of described steel mesh 10 and the first Printing Zone 11 direction setting of moving along steel mesh 10.

In other embodiment, first Printing Zone 11 can be provided with (not shown) along scraper 401 twice different motion track with second printing, 12 districts on the steel mesh 10.Second cleaning device 22 of this moment and first cleaning device 21 also are arranged on apart from second printing 12 districts and the most close position, first Printing Zone 11.

In the preferred forms shown in Figure 4, not only first Printing Zone 11 and second Printing Zone 12 are provided with along the axis 13 that steel mesh 10 moves on the steel mesh 10.And second cleaning device 22 and first cleaning device 21 also be provided with along the axis 13 that steel mesh 10 moves.

In the said mechanism, aim at PCB circuit board 30 positions for one in first Printing Zone 11 or second Printing Zone 12, in first cleaning device 21 or second cleaning device 22 aims at another Printing Zone so.

Described aligning is expressed as the center that the second Printing Zone center line 120 is aimed at PCB circuit board 30 on Fig. 1 and Fig. 2, and the center of the first Printing Zone center line, 110 first cleaning devices 21.

Or the center of the first Printing Zone center line, 110 aligning PCB circuit boards 30, and the second Printing Zone center line 120 is aimed at the center of second cleaning device 22.

Described cleaning device is aimed at the Printing Zone and is comprised two kinds of embodiments, first kind of embodiment:

After steel mesh 10 moves second cleaning device 22 or first cleaning device 21 are positioned under second Printing Zone 12 or first Printing Zone 11 just, that is to say that the distance between second Printing Zone 12 and first Printing Zone 11 was clipped to distance between second cleaning device 22, first cleaning device 21 in 30 minutes near the PCB circuit board.

Second kind of embodiment:

Distance between second Printing Zone 12 and first Printing Zone 11 is different from the PCB circuit board and was clipped to distance between second cleaning device 22, first cleaning device 21 in 30 minutes.Second cleaning device 22 or first cleaning device 21 are moved under second Printing Zone 12 or first Printing Zone 11 by 200 controls of computer master control system.

In the said mechanism, as shown in Figure 3, described computer master control system 200 drives steel mesh 10 shift positions, be to drive steel mesh 10 by steel mesh driver 101 to move, and the signal of reception steel mesh position signalling sensor 105 is determined the position of steel mesh 10.

In the said mechanism, described steel mesh position signalling sensor 105 can be arranged in preferred forms on the steel mesh moving track of steel mesh 10, described steel mesh moving track has many kinds to select and can adopt, for example guide rail, chute etc. because it is ripe prior art, are not done detailed description at this.

In the said mechanism, steel mesh driver 101 also is ripe prior art, it comprises driving power source, transmitting device, transmitting device connects steel mesh 10 and drives power source, drive the accurate control that power source is subjected to computer master control system 200, make steel mesh 10 can arrive position accurately, and provide the signal that puts in place, stop driving the running of power source by computer master control system 200 by steel mesh driver 101 by steel mesh position signalling sensor 105.

Described driving power source comprises electro-motor, pneumatic and hydraulic test.Preferred equipment is electro-motor.Certainly employing is pneumatic also can realize the purpose of this utility model with hydraulic test.

It all is mature technology in the vision printer of prior art that Fig. 3, print system 400 shown in Figure 4, optics alignment system 300, PCB circuit board are carried clamping system 500, but in the utility model, scraper 401 in the print system 400 is scraped first Printing Zone 11 at every turn or only, or only scrapes second Printing Zone 12.

Whenever, when second Printing Zone 12 need be cleaned again, computer master control system 200 drives steel mesh 10 shift positions, make first Printing Zone 11 of steel mesh 10 aim at PCB circuit board 30 positions, a plurality of PCB circuit boards 30 are printed second Printing Zone 12 that this moment second, cleaning device 22 was aimed on the steel mesh.

Facts have proved, the utility model is provided with two covers or the cleaning device more than two covers in vision printer, simultaneously the Printing Zone in the steel mesh is also increased to two or more, and steel mesh can be moved, and the computer master control system improved, increase is to the mobile control of steel mesh, increase is to the control of cleaning device, improvement is to the control of scraper, like this, when target P CB circuit board is printed, just can carry out cleaning to idle Printing Zone, needn't interrupt printing, thereby productivity ratio is improved greatly.
