Problems solved by technology

Since the double-sided tape does not need curing time, it can be considered as sealed after the solar frame is clamped, thus greatly shortening the production and turnaround time. It has been used by some solar module manufacturers, but due to the sealing and bonding of the double-sided tape itself Lijun does not meet the requirements of existing solar modules, and the aging resistance of double-sided tape is not suitable for long-term outdoor work, and the cost is relatively high compared to silicone, so this method is not ideal for sealing solar modules

Embodiment 1

[0042] Such as figure 1 As shown, the solar module is composed of a solar laminated panel 4, a solar module sealing material 3, a solar aluminum frame 2 and a junction box. Among them, the solar laminated panel is composed of a front panel (mostly glass), connected battery sheets, packaging materials (such as EVA), and a back panel after lamination. The solar panel is sealed with a sealing material and installed in the solar frame, and a junction box is installed on the back of the solar panel to output the current formed by photoelectric conversion.

[0043] Such as figure 2 As shown, the heat-adhesive polymer sealing material 3 is placed on the periphery of the solar laminated panel 4, and then the solar aluminum frame 2 with grooves is clamped to the solar laminated panel 4, and fasteners (these fasteners can be screws or right-angle bolts, etc.) vertically connect the long frame and the short frame of the solar energy, clamp the long and short frames of the aluminum fr...

Embodiment 2

[0047] Place the induction head directly above the solar framing machine without using a transfer line, such as Figure 5 , the solar laminated panel is installed on the frame through the module frame machine, and there is a pre-installed sealing material inside the frame (the sealing material is silane grafted polybutene and ethylene-propylene copolymer with a mass ratio of 1:1), and screw Or the right-angle bolts vertically connect the long frame and the short frame of the solar energy, and clamp the long and short frames by external force, so that the sealing material evenly wraps the edge of the solar laminate in the groove, and is affected by a certain elastic force. At the same time, there is a double-wound induction head 5 above the solar framing machine. The induction head generates a magnetic field. Due to electromagnetic induction, the aluminum frame will generate an internal current under the action of the magnetic field of the sealing head, and then convert the elec...

Embodiment 3

[0049] Such as Image 6 As shown, the induction coil of the induction-type sealing head adopts a single-wound strip-shaped structural frame, and the induction heating components of the induction-type sealing head are two sets of parallel first and second induction heating components, and the first and second induction heating components are arranged respectively. The second induction sealing head, the first and second induction sealing heads are respectively composed of two sets of induction heating components, the first and second induction sealing heads form an angle of 90°; the heating under the first induction sealing head The range is the first induction area, and the heating area under the second induction sealing head is the second induction area, and the two induction areas are perpendicular to each other on the same plane. The first inductive sealing head first heats and seals the two parallel sides of the aluminum frame of the solar module, then the solar module move...

Abstract

The invention provides an induction sealing method for a solar component. According to the induction sealing method, the solar component provided with a frame, sealing material and a solar laminated panel is arranged under an induction sealing head, the aluminum frame generates induction current inside under the action of the magnetic field of the sealing head, then the electric energy is converted into heat energy, the sealing material is gradually heated under the action of the heat energy to wrap and adhere the edge of the solar laminated panel and a groove of the aluminum frame and fill the gap between the edge of the solar laminated panel and the groove of the aluminum frame, so that the sealing effect is played. According to the induction sealing method specially designed for the solar component, the technology is simple, the sealing method is safe and environment-friendly, the sealing time is short, and the encapsulation effect for the solar component is superior.

Description

technical field [0001] The invention relates to the field of sealing technology, in particular to a sealing technology applied to solar modules. Background technique [0002] Nowadays, due to the requirement for the continuous working life of solar modules to reach 20 to 30 years, after the solar module is laminated, it is necessary to seal the edge of the laminate and install the frame. Good edge sealing materials and processes can achieve sealing , bonding, shock resistance, water vapor barrier and other functions, so as to ensure the normal operation and performance of solar modules in harsh natural environments. [0003] At this stage, solar modules are mainly composed of solar laminated panels, sealing strips, solar frames, and junction boxes. Among them, the solar laminated panel is composed of a front panel (mostly glass), connected battery sheets, packaging materials (such as EVA), and a back panel after lamination. The solar panel is sealed with a sealing material...
