Embodiment 1

[0045] Such as figure 1 As shown, the solar cell string used in this embodiment contains two cells (1, 1'), and the two lengths are L 1 The first conductor strips 4 located below the first cell and above the end cell respectively, a set of length L 2 And connect the second conductor strip 5 of two battery slices (1, 1'), the two battery slices are separated by a distance of length S.

[0046] Such as Figure 5 with Image 6 As shown, a method for preparing a solar cell string, two cells (1, 1') and a group of second conductor strips 5 are placed, and the transport device carrying the cells moves forward for a distance of T, T= 2*(S+the length of a single cell), for the cells and conductor strips delivered to the welding station, the welding device completes the interconnection welding of two cells (1, 1') and a set of conductor strips 5 .

[0047] The specific implementation process is: place the first conductor strip 4, the first battery piece 1, the second conductor stri...

Embodiment 2

[0050] Such as Figure 7 with Figure 8 As shown, the difference between Embodiment 2 and Embodiment 1 is that, in the specific implementation process, before the transmission mobile device moves forward, the first conductor strip 4 is first placed on the second battery sheet 1', and the transmission mobile device moves forward. After the length is the distance of T, T=2*(S+length of a single battery sheet), the welding device performs mutual exchange of two battery sheets (1, 1'), two groups of first conductor strips 4 and one group of second conductor strips 5 Even welding. All the other are identical with embodiment one.

Embodiment 3

[0052] Such as figure 2 As shown, the solar cell string used in this embodiment contains 6 cells (1, 1', 2, 2', 3, 3'), and two sets of length L1 are respectively located under the first cell and the end cell The upper first conductor strip 4, 5 second conductor strips (5, 5', 5", 5 with a length of L2 and connecting 6 battery pieces (1, 1', 2, 2', 3, 3') 3 ', 5 4 '), two adjacent groups of cells are separated by an interval of length S.

[0053] Such as Figure 9 with Figure 10 As shown, a method for preparing a solar battery string provided by this embodiment is specifically: when placing two battery sheets (1, 1') and two sets of second conductor strips (5, 5'), the carrying battery The transmission and moving device of the sheet moves forward for a distance of T, T=2*(S+length of a single cell), and the welding device completes two cell sheets (1, 1 ') and the interconnection welding of two sets of conductor strips (5, 5').

[0054] In this embodiment, when the wel...

Abstract

The invention provides a method for preparing a solar cell string, which mainly overcomes the technical defects of long battery string production time and low production efficiency in the prior art. According to the main technical scheme, when at least two cells and at least one set of second conductor belts are placed each time, the forward movement length of a conveying and moving device for bearing the cells is T, T is equal to the product of n and the sum of S and the length of a single cell, n is greater than or equal to 2, and for the cells and the conductor belts conveyed to the weldingstation, a welding device completes interconnection welding of the at least two cells and the at least one set of second conductor belts. The invention further provides equipment for preparing the solar cell string and implementing the method. The method and the equipment provided by the invention remarkably save the conveying and moving time of the cells, and reduce the action frequency of a driving component, thereby reducing the loss of the driving component, and improving the working efficiency of the string welding equipment.

Description

technical field [0001] The present invention relates to methods and apparatus for producing strings of solar cells. Background technique [0002] In the automated battery string manufacturing process, the interconnection of battery slices requires a set of conductor strips to connect the front of the battery slice to the back of the adjacent battery slice, and a distance of length S is left between adjacent battery slices. The equipment continuously and alternately places conductor strips and battery sheets, and transmits and welds them to form an interconnected battery string. The structure of the battery string is shown as figure 1 shown. [0003] In the prior art to manufacture the battery string with the above structure, the technical solutions adopted are mainly as follows: image 3 As shown, before the interconnection and welding of the battery slices and the conductor strips, the usual way of laying out the battery slices is: arranging the first conductor strip 4 of...
