Embodiment 1

[0071] The present embodiment provides a kind of production method of solar panel, comprises the following steps:

[0072] (1) if Figure 2 ~ Figure 3 As shown, a single battery piece 1 is connected in series into a battery string 2 by a stringer, and the positive and negative electrodes of adjacent battery pieces 1 are welded by interconnecting bars 4 .

[0073] Using a stringer to weld a single battery piece 1 into a battery string 2 is more efficient than manual welding, and the yield is higher; and it is more accurate, ensuring that the battery piece 1 does not shift back and forth; after the string welding is completed, the battery string 2. Check to see if there is any false welding or whether the cell 1 is damaged, so as to eliminate unqualified products.

[0074] (2) if figure 1 As shown, the tempered glass plate 11, the first packaging adhesive layer 12, the battery pack 13, the second packaging adhesive layer 14 and the back plate 15 are sequentially stacked to for...

Embodiment 2

[0093] see Figure 7 , the difference between this embodiment and embodiment 1 is:

[0094] The heat shield 3 is transparent, the horizontal calibration line 31, the bus bar placement line 32, and the interconnection bar reference line 33 are all dark lines; the workbench 6 is placed on the ground, and the table top of the workbench 6 61 is transparent glass, the side wall 62 of workbench 6 is a solid baffle, and workbench 6 is provided with illuminating lamp 63 inside.

[0095] Because the calibration and welding of the interconnection bar 4 and the bus bar 5 need sufficient brightness, but generally the workshop for producing solar panels is very empty, the light distance is relatively long, and the light intensity is not enough; if a separate light source is set around the workbench 6, it will It takes up extra space and affects the operation of the staff.

[0096] Therefore, the light source is arranged in the inside of the workbench 6, which will not affect the operatio...

Embodiment 3

[0098] The difference between this embodiment and embodiment 2 is:

[0099] see Figure 8 , the manipulator 10 is provided with a row of Bernoulli suction cups 7 for absorbing the battery slice 1 and carrying the battery string 2 .

[0100] see Figure 9 ~ Figure 10 , the Bernoulli suction cup 7 includes a suction cup body 71, a first suction cup core 72 fixed in the suction cup body 71, a second suction cup core 73 fixed in the first suction cup core 72, the underside of the first suction cup core 72 is in contact with An air outlet passage 74 is formed between the lower sides of the second suction cup core 73, and an air inlet passage 75 communicating with the top of the second suction cup core 73 is provided in the second suction cup core 73, and the inner wall of the second suction cup core 73 is provided with The air outlet hole 76 that communicates with the air inlet passage 75 and the air outlet passage 74; There is a connecting frame 78 for installing the suction cu...

Abstract

The invention discloses a production method for a solar cell panel, and the method comprises the steps: putting a tempered glass plate, a packaging glue layer, a battery pack, a packaging glue layer and a backboard, which are all stacked sequentially, into a vacuum laminating machine, carrying out the hot-pressing of the solar cell pack, taking out the formed solar cell pack, and adding a frame and a wiring box to manufacture a solar cell panel; A thermal insulation plate is added in the stacking process for thermal insulation and calibration, and a battery string is carried through a Bernoulli sucking disc. The interior of the wiring box is provided with a bypass diode, thereby guarantee the connection of a circuit. The method is reasonable in design, achieves the operation optimization of the carrying, layout, welding and wiring of a battery piece, improves the quality of a product, and guarantees the photoelectric conversion efficiency of the solar cell panel.

Description

technical field [0001] The invention relates to the photovoltaic field, in particular to a production method of a solar cell panel. Background technique [0002] A solar cell is a device that uses the photoelectric effect to directly convert solar energy into electrical energy. The material of solar cells is mainly crystalline silicon. At present, the common solar cells on the market are 125*125mm monocrystalline silicon or 156*156mm polycrystalline silicon. The output power of a single cell is small, so generally multiple cells Connected in series to form a square array of solar cells with larger output power. [0003] The front electrode of the battery sheet represents the negative electrode, and the back electrode represents the positive electrode. The front electrode of the previous cell is connected to the back electrode of the latter cell through interconnecting strips, and all the cells are connected in series to form a whole. The front of the battery sheet is prov...
