Description
Technical field
The present invention relates to technical field of sealing technology, be specifically related to a kind of Sealing Technology being applied to solar components.
Background technology
Now, owing to requiring to reach 20 years to 30 years for the continuous firing time limit of solar components, therefore solar components is after lamination is complete, need to carry out sealing and frame for installing to the edge of laminate, good edge seal material and technique can realize the functions such as sealing, bonding, antidetonation, aqueous vapor obstruct, thus ensure that solar components normally works and retention in harsh natural environment.
Present stage, solar components was primarily of solar energy laminated panel, sealing joint strip, solar energy frame, and terminal box forms.Wherein solar energy laminated panel forms by after header board (mostly being glass), the cell piece connected, encapsulating material (as EVA), backboard lamination.Solar panel loads in solar energy frame after encapsulant sealing, installs terminal box at solar panel back simultaneously, so that the electric current formed by photoelectric conversion exports.
Existing solar components sealing means mainly uses silica gel and uses two-sided tape two kinds.Wherein, silica gel sealing using method is: in the groove of aluminium frame, squeeze into a certain amount of silica gel special, laminated compenent is snapped in the groove of solar energy aluminium frame of silica gel, then be connected vertical to long margin frame and short frame with screw or right angle latch, by External Force Acting, length frame is clamped, finally after silica gel solidification, complete sealing.Silica gel sealing advantage is used to be that equipment is simple, input cost is few, silica gel performance base instinct meets the requirement that solar components uses for a long time, most solar components production company takes this kind of mode, but its curing time long (more than 24 hours), and follow-up scale removal process trouble, smell is unfavorable for environmental protection more greatly, and impact is had enough to meet the need, be not suitable for the defects such as automated production is also use the unavoidable problem of silica gel sealing in present stage solar components production.
Relative, use two-sided tape need first by adhesive tape manually or instrument evenly adhere to laminate all around, again reeded for band solar energy frame clamping is installed the laminate of adhesive tape, then be connected vertical to long margin frame and short frame with screw or right angle latch, by External Force Acting, length frame clamped.Because two-sided tape is without the need to curing time, therefore can think that sealing completes after being clamped by solar energy frame, thus substantially reduce production and turnaround time, use by part solar components manufacturing enterprise, but because the sealing of two-sided tape own and cohesive force are not all the requirements meeting very much existing solar components, two-sided tape resistance to ag(e)ing is also not suitable for long-term outdoor work, and cost is higher relative to silica gel, and institute is also not satisfactory for sealed solar energy assembly in this way.
Induction sealing refers to the magnetic field that induction power supply is formed by induction end socket (induction coil), due to electromagnetic induction effect, encapsulant (as aluminium foil) produces electric energy in magnetic field, and electric energy Internal reforming at encapsulant be heat energy, the polymer (inner lining material) on encapsulant (as aluminium foil) will be coated melt along the edge of sealer, now with the pressure acting in conjunction be added on the edge of sealer, make built-in sealing melt edge in sealer, thus produce the process of close encapsulation.Because the firing rate of induction heating sealing is fast, energy-conservation, efficiency is high, easily realize the advantages such as automation, it is of wide application, by large-scale application in packaging, solidification industrial goods and consumer product area, common are seal bottle cap, can, inlay the modes such as sealing ring.
Summary of the invention
In order to overcome above defect, the technical problem to be solved in the present invention is to provide a kind of induction sealing method that can be used on solar components, and the sealing property that sealing method is brought is lasting, ageing-resistant.
Technical scheme of the present invention is, a kind of induction sealing method of solar components, comprise solar energy laminated panel, be positioned at aluminium frame and the encapsulant of solar energy laminated panel periphery, and for making the induction type seal head of encapsulant hot melt, described aluminium frame has the groove for fixed solar laminated panel
Described induction sealing method at least comprises the following steps:
(1) polymer encapsulating material of hot sticky type is placed on solar energy laminated panel periphery, then reeded solar energy aluminium frame is blocked solar energy laminated panel, be connected vertical to solar energy long margin frame and short frame with securing member, by the long and short frame clamping of External Force Acting by described aluminium frame, make polymer encapsulating material in the groove of aluminium frame, evenly wrap the edge of solar energy laminated panel, and be subject to the effect of certain elastic force, obtain solar components;
(2) solar components that frame and encapsulant are housed is placed on below induction type seal head, carries out electrical induction sealing;
(3) the induction type seal head described in produces magnetic field, under the magnetic fields of induction type seal head, aluminium frame is made to produce induced current in inside, then heat energy is converted electrical energy into, under heat energy effect, encapsulant is gradually heated by the sonochemical activity, and wraps up, bonds the groove of solar energy layer pressure surface panel edges and aluminium frame, fill full space between the two, play sealing effectiveness;
(4) after described polymer encapsulating material melts completely, solar components is cooled away from top pressure closure, realize the fast sealing of solar components.
The determination principle of induction coil size makes it to close with the matching form of solar components sealing strip, is advisable in the uniform field for sealing that its size will adapt with the size that can produce one and solar components sealing strip simultaneously.The size of the size of induction sealing head induction coil specifically, the length and width size of what its length and width were corresponding is solar components, object is the induced field just in time corresponding metal edge frame region that induction coil is produced, and makes metal edge frame produce induced current and starts heating.Meanwhile, be rectangle solar energy frame according to sealed object, induction head design is become the rectangular configuration slightly larger in length and width than solar energy frame, and the sealing effectiveness of acquisition is better.
