Abstract
The utility model provides an aluminium frame for crystalline silicon printing; the aluminium frame for crystalline silicon printing is a square closed frame and is formed by two basic elements, namely, rims and connecting corners, the rims are connected with the connecting corners in a welding way, and a thread positioning hole for printing is machined in the connecting corner. The aluminium frame for crystalline silicon printing has the following advantages: being connected in a welding manner by adopting high-strength aluminium profile and solid aluminium profile, being capable of effectively reducing the weight of aluminium frames produced in a casting manner normally; reducing the use quantity of aluminium profile, greatly saving cost; solving the embarrassed situation that the transportation expense for manufacture factories is high; and being applicable to screen extension of various screen printing plates for crystalline silicon printing.
Description
Technical field
The utility model relates to printing technology, and the aluminium frame is used in particularly a kind of crystalline silicon printing.
Background technology
Serigraphy is a kind of ancient printing process, and it belongs to porous printing, is called as four big printing processes with offset printing, protruding seal, gravure.In porous printing, most widely used is serigraphy, so screen painting is called as omnipotent printing, and it can print on various printable fabrics, such as materials such as various plastic products, textile, metal, glass, potteries.We can say to dewater and (comprise other liquids and gases) beyond the air that any object can be as stock.It is electronics industry, ceramic applique industry, textile printing and dyeing industry the most widely that China uses serigraphy.In recent years, packing and decorating, advertisement, poster label etc. also adopt serigraphy in a large number.Silk, nylon, polyester fiber or stainless steel metal silk screen are stretched tight on screen frame, its tensioning is fixed, adopt manual method of carving paint film or photochemistry plate-making to make screen printing forme.Traditional method for platemaking is manual, and what the modern times more generally used is the photochemistry graphic arts process.The photochemistry graphic arts process is to utilize photosensitive material to make screen printing forme through photomechanical method; Making the silk screen hole of picture and text part on the screen printing forme is penetrating hole; And the screen mesh of non-graphic part is plugged, and silk screenink is put into screen frame, and pressurizeing in screen frame with the rubber sdueegee scrapes; At this moment printing ink is transferred on the stock through the mesh of picture and text part, forms the picture and text the same with original copy.Screen printing apparatus is simple, easy to operate, plate making is simple and easy and with low cost, adaptability is strong.The serigraphy applied range not only can carry out in the plane, can also on curved surfaces such as cylinder, cone, carry out.
Eighties of last century is since the nineties; Under the pressure of energy crisis and global warming; Along with the continuous attention of various countries to solar energy research, scientific research and industry input constantly increase, get a series of scientific achievement; Conversion efficiency of solar cell is constantly refreshed, and has established the technical foundation that large-scale industrial is produced.Solar energy utilization at present can be divided into solar heat power technology, solar water technology and solar-photovoltaic technology three bulks.Solar-photovoltaic technology utilizes the photovoltaic effect principle of semiconductor equipment, is with fastest developing speed, the most great-hearted renewable energy utilization technology in this year.Present global major country is all developing photovoltaic generation as the principal mode that utilizes solar energy.Along with the reduction of solar cell cost and the raising of conversion efficiency, it is more and more obvious as the trend of the principal mode that solar energy utilizes.
Therefore along with the reaching its maturity of solar energy generation technology, the requirement to half tone in the solar energy crystal silicon cell sheet printing process is also progressively improving.It is die cast that the aluminium frame that generally domestic printing industry is used is spoken more, and the flatness of this type aluminium frame is difficult to guarantee, therefore increases cost of transportation because the die cast product is a solid in addition.
The conventional solar energy crystalline silicon printing of using is as shown in Figure 1 with the aluminium frame, is disposable die cast product.There is following shortcoming in it:
1, widely used die casting aluminium frame is owing to be that one-shot forming so screen frame flatness are not high;
2, because be the heavier increase cost of transportation of solid so weight.
The utility model content
For the crystalline silicon printing that solves present use with screen frame weight and the not high problem of flatness, the utility model provides following technical scheme:
The aluminium frame is used in a kind of crystalline silicon printing; Said crystalline silicon printing is a closed framework of square with the aluminium frame; Be made up of frame and two kinds of primary elements of joint angle, frame is connected through welding manner with joint angle, the screw thread locating hole of machining printing usefulness on the said joint angle.
A nearlyer step, said frame is a hollow high-strength aluminium section bar.
A nearlyer step, said joint angle is the solid aluminium section bar.
A nearlyer step, four jiaos of protrusions of said joint angle, and pass through the flatness that machining guarantees framework.
The utility model advantage is:
1, adopt high strength Aluminum Hollow section bar to reduce greatly as the screen frame weight that four limits connection frame is.
2, adopt four jiaos of solids to connect and guarantee the screen frame flatness through machining.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Use the aluminium frame like Fig. 2, a kind of crystalline silicon printing shown in 3; Said crystalline silicon printing is a closed framework of square with the aluminium frame; Form by frame 1 and 2 two kinds of primary elements of joint angle; Frame 1 and joint angle 2 are connected the screw thread locating hole 3 of machining printing usefulness on the said joint angle 2 through welding manner.Said frame 1 is a hollow high-strength aluminium section bar; Said joint angle 2 is the solid aluminium section bar; Four jiaos of protrusions of said joint angle 2, and pass through the flatness that machining guarantees framework.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
