Abstract
The invention relates to a novel nodeless screen in the solar cell screen printing technology and belongs to the field of solar photovoltaic cell manufacturing. The novel nodeless screen is characterized in that firstly, net-structured grooves are formed in a metal base plate, then polyester materials are poured onto the base plate, and after cooling down, the materials are taken off from the base plate. According to the novel nodeless screen, one yarn exists at every cross, while two yarns exist at every cross of a traditional screen, so that the printing consistency and the grid line height-width ratio of the novel nodeless screen are more optimal than those of the traditional screen, and the size utilization rate is higher; meanwhile, the technology of manufacturing screens by pouring polyester materials on grooved metal base plates is lower in price than methods of manufacturing nodeless screens through electroforming.
Description
Technical field
The present invention relates to a kind of new silk screen without node in silicon solar cell silk-screen printing technique, belong to solar-energy photo-voltaic cell and manufacture field.
Background technology
Crystal silicon solar energy battery conventional production process is very ripe at present, and silk-screen printing technique is very extensive as one process application in silicon solar cell conventional production process, and the making of silk screen is the core of half tone technique.Traditional silk screen making step is generally: throw the net, degreasing, coating, exposure, development, shipment check several key steps.The silk screen that traditional handicraft is made has node, and the figure of printing often has some shortcomings, such as grid line edge, is not that very smooth, grid line height has reduction, slurry utilization rate and decreases etc.But existing often higher without node silk screen cost of manufacture.
Summary of the invention
The object of this invention is to provide a kind of new silk screen without node, solve some shortcomings of traditional silk-screened, such as grid line edge be not very smooth, grid line height has reduction, slurry utilization rate decreases etc., can reduce the cost of manufacture of silk screen by the present invention.
The object of the invention is to be achieved through the following technical solutions, a kind of new silk screen without node, is characterized in that, described silk screen is first scribed cancellated groove on metal substrate, at substrate upper polyester material, after material cooled, it is taken off from substrate.
The semicircle that is shaped as 18 microns to 30 microns of internal diameters of the groove on described metal substrate; Order number is 200 order to 400 orders.
Described polyester material is for being PET PET or aromatic polyester fiber.
The present invention is equivalent to a rhizoid line at the longitude and latitude intersection of silk thread, and traditional silk screen is equivalent to two rhizoid lines at the longitude and latitude intersection of silk thread, so the present invention is more excellent compared with traditional silk-screened continuity, grid line depth-width ratio, slurry utilization rate is higher, and cutting is built the technique of making silk screen and made lower without node silk screen cost compared with electrocasting method on metal substrate.
Accompanying drawing explanation
Fig. 1 is that the present invention overlooks pictorial diagram;
Fig. 2 is side-looking pictorial diagram of the present invention;
Fig. 3 is that existing silk screen is overlooked pictorial diagram;
Fig. 4 is existing silk screen side-looking pictorial diagram;
In figure, 1 groove.
The specific embodiment
Progressive explanation the present invention in conjunction with the accompanying drawings and embodiments, the present invention first be take metal material as substrate, as shown in Figure 1 and Figure 2, scribes cancellated groove 1 on substrate, the order number of scribing is 200 order to 400 orders, the semicircle that is shaped as 18 microns to 30 microns of internal diameters of groove 1; After completing, the substrate manufacture of corresponding order number builds polyester material on substrate, after material cooled, it is taken off from substrate, just completing without node screen cloth of corresponding order number, then making step is with traditional silk screen manufacture craft, complete the steps such as degreasing, coating, exposure, development, shipment inspection, without the moulding of node silk screen.As shown in Figure 2 and Figure 3, there is node in existing screen net structure.
