Description
Technical field
The utility model relates to a kind of scraper for silk-screen printing that suppresses flash.
Background technology
Now in solar cell industry, the grid line of cell piece and aluminium back surface field are by silk-screen printing technique, to be printed onto the front and back of silicon chip.
Current screen process press is by the pressure between scraper and screen process press, to make to be positioned over slurry on silk screen to be penetrated into and on silicon chip, to be completed printing by screen mesh; Scraper comprises forward scraper for printing and for collect the returning charge scraper of slurry when forward scraper returns.Forward scraper and the setting parallel to each other of returning charge scraper, be all installed on tool rest, respectively at elevating mechanism, is connected.Between forward scraper and returning charge scraper, there is interval; When forward prints, returning charge scraper rises, and when returning charge scraper, forward scraper rises.
In the process of using in reality, in the process of forward scraper and the motion of returning charge scraper, a large amount of slurries can and overflow from top along forward scraper and returning charge scraper from the gap between forward scraper and returning charge scraper, finally hoard the outside at forward scraper and returning charge scraper, the time of hoarding is longer, the slurry solidifying just can not get sufficient utilization, causes slurry waste, has increased the manufacturing cost of cell piece.
Therefore, providing a kind of scraper for silk-screen printing that can reduce slurry waste, raising printing efficiency is the technical problem that those skilled in the art need solution badly.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of scraper for silk-screen printing that can reduce slurry waste, improve printing efficiency is provided.
For achieving the above object, the technical solution of the utility model is a kind of scraper for silk-screen printing that suppresses flash, comprises forward scraper and returning charge scraper, and forward scraper and returning charge scraper be arranged in parallel, are fixed on tool rest, and tool rest is connected with elevating mechanism; Between forward scraper and returning charge scraper, have interval, its bottom surface is in same level; Between forward scraper and returning charge scraper, be provided with discharging box, discharging box is fixed on tool rest, and the bottom surface of discharging box is provided with Lou material seam, and upper bottom surface is provided with stock inlet, and the bottom surface of discharging box is higher than the bottom surface of forward scraper.
In order to control Lou material, measure to reach better anti-flash effect, preferably, the stock inlet of described discharging box makes progress and is connected for storing the material storage tube of slurry; Between described material storage tube and described discharging box, be provided with charging by-pass valve control.
In order to make the spillage amount of discharging box more accurate, preferably, described material storage tube is provided with for controlling to the feeding control system of discharging box feeding flow, comprises the meter for being metered into described discharging box amount of slurry, described charging by-pass valve control and the metering result of meter and setting value relatively and according to difference comparative result are carried out to self-adjusting controller to the valve opening of charging by-pass valve control.
In order to prevent that slurry from storing process because of the change of variations in temperature generation viscosity, preferably, described material storage tube is provided with heat-insulation layer.
In order to make the slurry of discharging box evenly be sprinkled upon serigraphy district, preferably, described leakage material is sewed with some rows, and each row is parallel to described forward scraper.
For simplified structure, can only need a tool rest, preferably, described forward scraper, described returning charge scraper and described discharging box are fixed on same described tool rest.Because slurry is controlled, enter serigraphy district, while worrying forward scraper positive movement, slurry does not too much overflow from anti-material scraper one side, while worrying the counter motion of returning charge scraper, slurry does not too much overflow from forward scraper one side yet, make forward scraper and returning charge scraper be fixed on same tool rest, by an elevating mechanism, controlling lifting becomes possibility.In the case, discharging box can be fixed on same described tool rest, plays the effect of simplified structure.
Or, for the high load of discharging box in the situation that, between forward scraper and returning charge scraper, there are enough spaces to hold slurry, preferably, the bottom surface of described discharging box is adjustable with respect to the height of the bottom surface of described forward scraper; The stock inlet of described discharging box is communicated with by a Telescopic flexible pipe with described material storage tube.
Further preferably, described tool rest and described elevating mechanism all have three, comprise respectively first, second, third tool rest and first, second, third elevating mechanism; Described forward scraper, described returning charge scraper, described discharging box fix with first, second, third tool rest respectively, and the first tool rest is connected with the first elevating mechanism, and the second tool rest is connected with the second elevating mechanism, and the 3rd tool rest is connected with the second elevating mechanism.
Advantage of the present utility model and beneficial effect are: the scraper for silk-screen printing that suppresses flash of the present utility model by arranging the discharging box that can leak material between forward scraper and returning charge scraper, the direction of expecting by leakage is carried slurry to serigraphy district, having guaranteed that slurry can leak is gradually sprinkled upon silk screen surface, avoid using the disposable stand of traditional scraper slurry to overlay on the phenomenon that flash is easily caused on silk screen surface, thereby reduced slurry waste, improved printing efficiency.
