Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic module production, and in particular to a lamination device and method for photovoltaic modules. Background Art

[0002] When laminating photovoltaic modules, the laid cells are transferred to the laminator, the air in the module is extracted by vacuuming, and then the EVA is heated to melt, and the cells, glass and back sheet are bonded together; finally, the module is cooled and taken out. The lamination process is a key step in module production, and the lamination temperature and time are determined by the properties of EVA.

[0003] At present, before lamination, the existing photovoltaic modules are laminated synchronously for multiple photovoltaic modules, and in order to protect the laminated photovoltaic modules, the existing patent application number: CN201520529236.4 discloses: photovoltaic module lamination synchronous paper laying device;

[0004] That is, the existing method of laying paper at the bottom of multiple photovoltaic modules as an isolation layer can prevent the bottom of the module from directly rubbing against the laminator or other contact surfaces during the lamination process. At the same time, the paper laid on the top of multiple photovoltaic modules also plays a role of isolation and protection. The existing paper located at the bottom and top of multiple photovoltaic modules is laid manually. During the manual laying, especially the laying of the top paper, the paper is easily contacted with the surface of the photovoltaic module during the stretching process, resulting in the deviation of the arrangement position of the photovoltaic module, and then resulting in uneven spacing between multiple battery cells, which will cause defects such as parallel-series short circuit after lamination.

The rotating gear 103 is fixedly sleeved on the outer side of one of the support tubes 663.

[0081] Specific implementation process: that is, when the paper body 5 is transmitted between the two conveyor belts 6452 on both sides thereof, the adsorption roller 664 moves to a position close to the conveyor belt 6452 through the bottom of the moving member 8, and the two sets of conveyor belts 6452 continue to run, so that the paper body 5 moves to the adsorption roller 664, and then, the vacuum pump 666 is operated to form a negative pressure state in the hollow cavity of the adsorption roller 664, and the adsorption roller 664 stably and steadily adsorbs the paper body 5 through the multiple adsorption holes 6641 thereon. At this time, the conveyor belt 6452 continues to run, and the second electric push rod 101 is operated to move the push rack 102, and the push rack The bar 102 drives one of the support tubes 663 to rotate by rotating the gear 103, until the second electric push rod 101 stops running, then the support tube 663 drives the adsorption roller 664 to rotate 90 degrees, so that one end of the paper is rotated to the inner side of the pressing plate 667, and then, by pushing the cylinder 93 to operate, the wedge block 92 moves along the wedge opening 911, so that the pressing plate 667 moves along the adsorption roller 664, until one end of the paper body 5 is pressed and fixed between the pressing plate 667 and the adsorption roller 664, then the two support blocks 661 drive the paper body 5 to move along the laminator body 1 under the drive of the moving member 8;

[0082] Until one end of the paper body 5 at the support table 2 moves close to the laminator body 1, and at the same time, one end of the paper body 5 at the top positioning frame 3 moves close to the laminator body 1, at this time, the curled paper is unfolded to form a flat state;

[0083] Then, the photovoltaic module body is placed on the paper body 5 on the support table 2 in sequence, and then the paper body 5 near the conveyor belt 6452 is cut by the cutting knife 652. In this state, since the paper is laid for a long time and multiple photovoltaic modules are superimposed on the paper body 5, the paper body 5 will not be deformed after cutting.

While cutting, the vacuum suction plate operates to achieve adsorption and fixation of the unfolded paper body 5 to ensure that the paper body 5 after cutting does not move. Subsequently, the telescopic cylinder 72 operates to move the paper body 5 at its bottom through the vacuum suction plate until the paper body 5 moves down to the upper surface of multiple photovoltaic modules. The vacuum negative pressure at the vacuum suction plate slowly decreases, and the paper body 5 is stably covered on the upper surface of multiple photovoltaic modules due to its own gravity, thereby achieving the effect of stably covering the paper body 5.

[0088] A lamination method for a photovoltaic module lamination device comprises the following steps:

[0089] Step 1: First, the paper body 5 is stretched by the paper stretching mechanism 6 at the support platform 2. At this time, the paper at the top positioning frame 3 is also stretched to a certain length. Then, the paper body 5 is stably laid on the conveyor belt 21 at the support platform 2.

[0090] Step 2: sequentially and stably placing a plurality of photovoltaic modules on the paper body 5 on the support platform 2;

[0091] Step 3: After the cutting knife 652 is used to cut one end of the paper body 5 at the main body of the support platform 2, the vacuum suction plate located at the top positioning frame 3 is operated to stably adsorb the adjacent paper body 5. Subsequently, after the cutting knife 652 is used to cut the paper body 5 at the top positioning frame 3, the vacuum pump 666 located at the top positioning frame 3 stops running, and the telescopic cylinder 72 is slowly operated to stably lay the unfolded paper body 5 on the top of multiple photovoltaic modules;

[0092] Step 4: The adsorption roller 664 located at the support platform 2 is relatively lifted by the operation of the lifting cylinder 6611. At this time, the transmission belt runs to stably move the multiple photovoltaic modules with the paper protective layer laid to the inside of the laminator body 1, and perform synchronous and stable lamination of the multiple photovoltaic modules.
