A kind of solar cell frame
Technical field
The present invention relates to a kind of solar cell frame, belong to solar cell and manufacture field.
Background technology
Solar cell package frame refers to photovoltaic solar cell board component aluminium alloy extrusions fixed frame, holds up by force, increases the service life, be convenient to transport, install for fixing, sealed solar energy battery component, enhancing assembly.
The rectangular-shaped body that current solar cell frame is mainly assembled into by two long edge frame made of aluminum profiles and two short edge frame made of aluminum profiles, and in the packaging technology of edge frame made of aluminum profiles, be mainly connected by screw length frame.Namely on a frame, setting an installing hole, a mounting groove is set in another frame, by being inserted in mounting groove through installing hole by screw, connecting adjacent frame.But, use screw cross-under can not ensure the compactness of frame junction, on the contrary, screw can not be interted in place due to solar cell frame buckle cell panel, therefore use screw to connect the solar cell frame obtained, its stability and firmness are not high, and install inconvenient.
In the last few years, also started to occur using some plug-in unit to connect length frame.An aluminium section bar plug-in unit for such as square, two ends insert respectively noted glue aluminium section bar long margin frame and aluminium section bar minor face money in, realize connect.But use aluminium profile materials and parts, energy consumption is very large, and cost also increases thereupon.Meanwhile, if the aluminium section bar plug-in unit of one closed, quality becomes large, and then increases the weight of solar cell frame, affects its mechanical strength.Although also have the design alleviating its weight done for plug-in unit now, be that its internal structure is set to hollow-core construction, outside is the aluminium shape surface of plug-in unit.But the design of complete hollow reduces the intensity of plug-in unit, the solar cell frame stability of assembling thus is very low, battery component is longer for service time, the more chipping or phenomenon that comes off, therefore, the design carried out solar cell frame is concerning important.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of quality light, and intensity is large, solar cell frame easy for installation.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of solar cell frame, employing aluminium profile forms, comprise two pieces of frames that head and the tail mutually connect, two pieces of described frame docking formation rectangle, described frame junction is provided with detachable buckle, described frame cross section is " L " shape, described frame cross section comprises horizontal sides and vertical edge, described vertical edge hollow, described vertical edge is provided with train wheel bridge and lower plate away from horizontal sides one end, described train wheel bridge, lower plate is parallel with described horizontal sides, described train wheel bridge and lower plate and vertical edge form the mounting groove of " U " shape, described mounting groove is for inserting solar cell,
Described train wheel bridge is also provided with excessive glue groove near mounting groove side.
The surface-coated of described frame has coating, and described coating is grouped into by the one-tenth of following parts by weight: dispersant 12 parts, dimethylbenzene 22 parts, epoxy resin 17 parts, 3 parts, curing agent, talcum powder 5 parts, Nano titanium dioxide 6 parts, polystyrene 6 parts.
Being improved to further of technique scheme: be all arranged at intervals with multiple reinforcement in the hollow structure of described vertical edge.
Being improved to further of technique scheme: described mounting groove opening part width is less than mounting groove bottom width.
Being improved to further of technique scheme: described train wheel bridge length is less than lower plate length.
Being improved to further of technique scheme: described frame is " L " shape.
Being improved to further of technique scheme: described frame is " U " shape.
Beneficial effect of the present invention is: solar cell frame vertical edge of the present invention is the framework of hollow, is provided with reinforcement in hollow frame, and the weight alleviating frame entirety strengthens again the intensity of frame; Solar cell frame of the present invention changes the form of traditional four edges frame docking, adopts two frame docking can form the structure of rectangle, makes solar cell easy for installation; Train wheel bridge being also provided with excessive glue groove, when installing solar cell, not easily making the binding materials such as silica gel overflow; The surface-coated of frame has the coating comprising epoxy resin and curing agent, can improve the resistance to corrosion of solar cell frame, and then improves its performance.
