Specific implementation mode
Following specific examples is only the explanation to the utility model, is not limitations of the present invention, this
Field technology personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification,
But as long as all being protected by Patent Law in the right of the utility model.
The utility model is described in detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1：
According to Fig. 1~Fig. 3, a kind of printing equipment of polycrystalline silicon battery plate, including：One-step print frame 1, secondary printing
Frame 2, screen frame displacement frame 3 and cell piece locating rack 4.
One-step print frame 1 includes the first horizontal slide rail 11, first longitudinal direction sliding rail 12 and screen printer 13；Secondary printing
Frame 2 includes the second horizontal slide rail 21, second longitudinal direction sliding rail 22 and ink jet printing device 23；The height of first longitudinal direction sliding rail 12 is more than
The height of second longitudinal direction sliding rail 22, the first horizontal slide rail 11 are arranged in the outside of the second horizontal slide rail 21, second longitudinal direction sliding rail 22
And ink jet printing device 23 is divided into two groups of both ends for being separately positioned on the second horizontal slide rail 21.
According to Fig.2, screen printer 13 includes the grout outlet 131 and scraper 132 being arranged towards printing screen 5, is scraped
Knife 132 includes the first scraper and the second scraper, and the first scraper and the second scraper and the second scraper are separately positioned on grout outlet 131
It is provided with lifter 133 at the top of both sides, the first scraper and the second scraper.
It includes outer frame body 31 and shift unit 32 that screen frame, which shifts frame 3, and printing silk is fixed with by shift unit 32 in outer frame body 31
The lower section that frame 3 is shifted in screen frame is arranged in net 5, cell piece locating rack 4, and 5 surface of printing screen is provided with positioning mark 51, ink-jet print
Be provided with identifier on brush device 23, record has silk screen encoding of graphs information in positioning mark, identifier can identify the coding into
It includes lead screw and step-servo motor that row, which calls ink jet printing figure, shift unit 32, and the least displacement length of shift unit 32 is 15-
40μm。
According to Fig.3, printing screen 5 includes screen frame 501, silk thread 502, net knot 503, catch 504 and main grid area
505 and thin grid region 506.Wherein Fig. 3 is in order to ensure that the hint effect of each structure, 5 wire side part of printing screen have been done at amplification
Reason.
During present apparatus morning use, first by one-step print frame 1, falls screen printer 13 and be bonded printing screen 5
Silk-screen printing is carried out, the main grid of cell piece and thin grid are printed out, silk-screen printing includes two steps：First step, slurry is from grout outlet
131 fall on printing screen 5, from main grid area 505 and thin grid region under the action of the barrier effect of catch 504 and the first scraper
506 enter cell piece table surface, in ultra-fine grid printing process, due to that will necessarily include net in main grid area 505 and thin grid region 506
