[0028] Please refer to Figure 1 and Figure 2 .

[0029] The photovoltaic module laminating device provided by the embodiment of the utility model, comprising: laminating frame 20 and laminating support platform 10, laminating frame 20 is made of at least part of ferromagnetic material, for example, the lower layer of laminating frame 20 can be made of ferromagnetic material, or the structure of the left and right sides and / or the front and back sides of laminating frame can be made of ferromagnetic material, or the overall structure of laminating frame 20 can be made of ferromagnetic material, in addition, other positions of laminating frame 20 can also be made of ferromagnetic material, and the specific selection can be made according to actual needs, as long as the laminating frame 20 has the function of being magnetically adsorbed, wherein the laminating frame 20 can be welded by iron, and the surface of the laminating frame 20 needs to be smooth without burrs, and the inside of the laminating frame 20 needs to be polished smooth, and the protrusion, depression and other defect problems need to be ensured. The laminating support platform 10 is used for placing the photovoltaic module to be laminated, the laminating frame 20 is arranged above the laminating support platform 10 to limit the position of the photovoltaic module to be laminated, and the laminating support platform 10 is provided with a magnetic piece 11. When laminating, the photovoltaic module to be laminated needs to be placed on the laminating support platform 10, the laminating frame 20 is located above the photovoltaic module, that is, the laminating frame 20 and the photovoltaic module are located above the laminating support platform 10, and the magnetic piece 11 can adsorb the laminating frame 20 to press the photovoltaic module tightly on the laminating support platform 10. Since the laminating frame 20 is attracted by the magnetism of the magnetic piece 11 during the laminating process, the laminating frame 20 can be pressed tightly on the photovoltaic module to improve the balance of the stress, so that the warping problem of the glass of the photovoltaic module can be avoided, and the phenomenon that the glass appears broken pieces can be avoided, and thus the laminating quality of the photovoltaic module is ensured.

[0030] In some embodiments, the magnetic piece 11 is an electromagnet, and in addition, the photovoltaic module laminating device further comprises a control circuit connected with the electromagnet, and the control circuit is used for controlling the electrification or power-off of the electromagnet. The electromagnet can generate magnetism when electrified, and the magnetism disappears when powered off. How the control circuit controls the electrification or power-off of the electromagnet can refer to the prior art, and the embodiment will not be repeated here. The focus of the embodiment is to apply the electromagnet to the photovoltaic module laminating device. In the specific working process, after the laminating frame 20 and the photovoltaic module are placed on the laminating support platform 10, the control circuit is started to control the electromagnet to be electrified to generate magnetism, and then the laminating frame 20 is adsorbed; after the laminating is completed, the control circuit controls the electromagnet to be powered off, at this time, the magnetism disappears, and the photovoltaic module can be removed from the laminating support platform 10 to enter the subsequent process.

[0031] It should be noted that the electromagnet is only a preferred scheme, and in addition, the magnetic piece 11 can also select a permanent magnet. The advantage of the permanent magnet is that the structure is simple, and the manufacturing and use cost is low. The advantage of the electromagnet is that the magnetism is convenient to control, so as to conveniently take and place the photovoltaic module on the laminating support platform 10.

[0032] In some embodiments, considering that the photovoltaic module is generally in a rectangular structure, the laminating frame 20 is preferably a rectangular laminating frame, and a support 21 is arranged between the two long sides of the rectangular laminating frame. The support 21 can be selected as an iron rod, which is preferably perpendicular to the long side of the rectangular laminating frame and can be formed by welding with the rectangular laminating frame. The number of iron rods can be selected as multiple to ensure the structural stability of the rectangular laminating frame. In addition, in order to further strengthen the structural strength of the laminating frame 20, a reinforcing piece 22 is arranged at each corner position of the laminating frame 20. The reinforcing piece 22 can be selected as a sheet-shaped reinforcing piece. For example, for the rectangular laminating frame, one reinforcing piece can be arranged at each of the four corners to improve the anti-deformation ability of the rectangular laminating frame. The reinforcing piece can be formed on the rectangular laminating frame by welding.

[0033] In some embodiments, the magnetic member 11 includes two first magnets extending along the length direction of the rectangular laminating frame. The first magnet can be selected as a long rod type or a long strip type structure. The two long sides of the rectangular laminating frame are made of ferromagnetic material. The two first magnets correspond to the long sides of the rectangular laminating frame for adsorption, that is, the distance between the two first magnets is the same as the width of the rectangular laminating frame, and the length of the two first magnets can be slightly longer than the long side of the rectangular laminating frame.

[0034] In some embodiments, the magnetic member 11 includes two second magnets extending along the width direction of the rectangular laminating frame. The second magnet can be selected as a long rod type or a long strip type structure. The two wide sides of the rectangular laminating frame are made of ferromagnetic material. The two second magnets correspond to the wide sides of the rectangular laminating frame for adsorption, that is, the distance between the two second magnets is the same as the length of the rectangular laminating frame, and the length of the two second magnets can be slightly longer than the short side of the rectangular laminating frame. In addition, the two first magnets and the two second magnets can form a rectangular magnetic member 11 structure to adapt to the rectangular laminating frame, thereby improving the magnetic adsorption effect of the magnetic member 11 on the rectangular laminating frame.

[0035] In some embodiments, the control circuit further has a controller for controlling the energization time length of the electromagnet. The longer the energization time, the longer the compression and holding time of the laminating frame 20 on the photovoltaic module. The shorter the energization time, the shorter the compression and holding time of the laminating frame 20 on the photovoltaic module. By adjusting the energization time length, different laminating requirements can be met, thereby improving the adaptability of the laminating equipment to photovoltaic modules with different requirements. How the controller controls the energization time length of the electromagnet can refer to the prior art, and this embodiment will not be repeated here.

[0036] In some embodiments, the photovoltaic module laminating device further comprises a laminating frame taking and placing assembly, which is capable of placing the laminating frame 20 on the photovoltaic module to be laminated. The laminating frame taking and placing assembly can be a mechanical hand or other driving device capable of moving the laminating frame, for example, a lifting driving device such as a lifting cylinder or cylinder can be arranged above the laminating support platform 10, the laminating frame 20 is connected with the lifting driving device, and the lifting driving device is capable of lifting the laminating frame 20. After the laminating frame 20 is in contact with the photovoltaic module, the magnetic member 11 is capable of moving the laminating frame 20 relative to the lifting driving device, so that the laminating frame 20 is capable of pressing the photovoltaic module under the action of magnetic adsorption. In addition, for the laminating machine with a flip cover, one side of the flip cover is hinged to one side of the laminating support platform 10, the iron photovoltaic module is arranged on the lower surface of the flip cover and is capable of moving up and down relative to the flip cover. After the photovoltaic module is placed on the laminating support platform 10, the flip cover is flipped to make the laminating frame 20 contact with the photovoltaic module, and then the electromagnet is started to press the laminating frame 20 on the photovoltaic module. Compared with manual operation, the laminating frame taking and placing assembly can improve the taking and placing efficiency of the laminating frame 20 and reduce the labor intensity.

[0037] In some embodiments, the photovoltaic module laminating device further comprises a conveying assembly, which is capable of moving the photovoltaic module with the laminating frame 20 to the laminating support platform 10. The conveying assembly can be a roller conveyor. The conveying assembly can improve the conveying efficiency of the photovoltaic module. In addition, a high-temperature cloth 12 can be arranged on the laminating support platform 10, and the photovoltaic module can be placed on the high-temperature cloth 12. The high-temperature cloth 12 can prevent the photovoltaic module from sticking to the laminating support platform 10.

[0038] In some embodiments, the photovoltaic module laminating device further comprises a material detection sensor, which can be an infrared sensor or a pressure sensor, etc. The material detection sensor is used to detect whether the photovoltaic module is moved to the laminating support platform 10. The working principle of the material detection sensor can refer to the prior art, which will not be described here. The controller is connected with the material detection sensor. After the material detection sensor detects that the photovoltaic module is moved to the laminating support platform 10, the controller can control the electromagnet to be powered on, and after being powered on for a preset time, the controller can control the electromagnet to be powered off, thereby improving the automatic laminating level of the photovoltaic module and improving the work efficiency.
