The scraper device reduces the waste, improves the utilization rate of slurry, and reduces the problem brought by drying the slurry.
Description
Technical field
The utility model relates to a kind of doctor blade device that prevents spillage, is applied to the doctor blade device that prevents spillage in the solar cell manufacturing.
Background technology
Along with day being becoming tight of global energy, solar energy is subjected to the extensive attention of countries in the world with advantage such as pollution-free, that the market space is big.Solar cell has been widely used in various illuminations and the electricity generation system at present.
The electrode of the front and back of solar cell and aluminium back of the body field all are with electrocondution slurries such as method for printing screen printed silver, silver-aluminium and aluminium usually, form silver, silver-aluminium electrode and aluminium back of the body field through super-dry and sintering then.So in the solar cell manufacture process, serigraphy is an important procedure of producing solar cell, its printing quality (thickness, width, thickness uniformity) influences the technical indicator of battery sheet.
In the existing printing process, slurries such as silver-colored aluminium are generally relatively spread out on printing screen plate, flow to both sides in the slurry back that is squeezed, and cause that both sides are auxilliary opens, but do not scrape the slurry that spreads out on the limit in printing movement, and this has caused spillage.The spillage that the printing process intermediate range wins causes the slurry waste on the one hand, on the other hand, causes printing quality to descend.Slurry accounts for about 25% of slurry loss in the waste that extravagance caused on the half tone, and can produce phenomenons such as fragment, dry finish, disconnected grid because of the slurry drying caking.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of doctor blade device that prevents spillage is provided, and cuts the waste, improves the utilization rate of slurry, and reduces the problem that slurry drying brings.
To achieve these goals, a kind of doctor blade device that prevents spillage described in the utility model comprises scraper, scraper plate and scrapes board binding.Scraper is positioned at a side of scraper plate, scrapes the opposite side that board binding is positioned at scraper plate, scraper plate with scrape board binding and fixedly connected, scraper is fixedlyed connected with scraper plate.
Described scraper is made of the extension of gradually opening that straight line portion and two ends thereof are an angle setting, and the extension at these two ends and straight line portion surround open on one side space, scraper plate and scrape board binding and be arranged in this space.
The straight line portion of described scraper which is provided with the backflow of slurry opening.
The straight line portion of described scraper and two ends thereof are provided with the extension of gradually opening and connect by one section arc transition.
Described scraper, its length is greater than scraper plate and scrape board binding.
In the preparation of solar cell, the effect of scraper is that slurry is pressed in the small opening of silk screen.Scraper plate and scrape board binding and be used to clamp scraping article, the material of scraper plate generally adopts metal material.
The utility model is by being provided with scraper, can solve the slurry back that is squeezed and flow to both sides, causes both sides to spread out, thereby causes the problem of spillage, and scraper separates with the scraper anchor clamps, reserves the space to reduce that slurry is hoarded and from the back material loading.Further, by the backflow of slurry opening is set on scraper, after can guaranteeing to use for a long time, doctor back can not occur slurry yet and hoard phenomenon.
The beneficial effects of the utility model are: effective generation that must reduce dry finish; Reduced the employee and returned the number of times of scraping slurry, it is single inferior to reduce to per 4 single (just, back of the body silver)/per 3 by 1 (just, carrying on the back silver)/2 times (back of the body aluminium) of original every list; Help the further mixing of slurry in printing process; Cut the waste, improve the utilization rate of slurry.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the present utility model.
The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.Following embodiment just is used for further specifying implementation detail of the present utility model, is not used for limiting scope of the present utility model.
See also shown in Figure 1ly, a kind of doctor blade device that prevents spillage described in the utility model comprises scraper 1, scraper plate 2 and scrapes board binding 3.Scraper 1 is located at a side of scraper plate 2, scrape the opposite side that board binding 3 is positioned at scraper plate 2, scraper plate 2 with scrape board binding 3 and fixedly connected, scraper 1 is fixedlyed connected with scraper plate 2, fixedly connected can the realization by the attaching parts of using always between this three connects, rivets or the like such as screw, bolt connection, pin.
Described scraper 1 is made of the extension of gradually opening 4 that straight line portion and two ends thereof are an angle setting, the extension 4 at two ends connects straight line portion with certain radian, the extension 4 at these two ends surrounds open space on one side with straight line portion, scraper plate 2 and scrape board binding 3 and be arranged in this space.
Preferable, the straight line portion of described scraper 1 which is provided with backflow of slurry opening 5.Described backflow of slurry opening 5 can be multiple shape, such as rectangle, fan-shaped or the like.
Better, described backflow of slurry opening 5 is two, is symmetrical arranged with the center line of scraper 1.Certainly, backflow of slurry opening 5 also can be for more than two.
Further, described scraper 1, its length is greater than scraper plate 2 and scrape board binding 3.
Further, it can be to connect by one section arc transition that the straight line portion of described scraper 1 and two ends thereof are provided with the extension 4 of gradually opening, can adopting process one-body molded.Angle between described straight line portion and the extension, two ends 4 thereof can be greater than 90 degree.
Further, the material of described scraper plate 2 generally adopts metal material.
The utility model is by being provided with scraper 1, can solve the slurry back that is squeezed and flow to both sides, causes both sides to spread out, thereby causes the problem of spillage, and scraper 1 separates with the scraper anchor clamps, reserves the space to reduce that slurry is hoarded and from the back material loading.Further, by backflow of slurry opening 5 is set on scraper 1, after can guaranteeing to use for a long time, scraper 1 back can not occur slurry yet and hoard phenomenon.The utility model can cut the waste, improve the utilization rate of slurry, and reduces the problem that slurry drying brings.
In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
