Problems solved by technology

It can be seen that every time a cell is overlapped, the ribbon needs to be cut once, so the ribbon needs to be cut multiple times to overlap a battery string, resulting in low efficiency of battery string preparation

Embodiment 1

[0039] Such as Figure 1 to Figure 6 As shown, the present invention provides a method for preparing a battery string, comprising the following steps:

[0040] 1) Cell 1 arrangement:

[0041] A plurality of first stages 3 are arranged in sequence along the left and right directions, and a cell 1 with the back facing up is laid flat on each first stage 3; each cell 1 is located at the same height; each cell 1 is provided with a front edge The electrode 11 and the back electrode 12; the front edge electrode 11 is located on the front right edge of the battery sheet 1 where it is located (or the left edge, the right edge is used as an example in each figure); the left and right sides of the same battery sheet 1 , wherein the side edge close to the front edge electrode 11 is the first edge 13, and the side edge far away from the front edge electrode 11 is the second edge 14; the first battery sheet 1 on each first carrier 3 The sidelines 13 are facing the same in the left-right ...

Embodiment 2

[0053] On the basis of implementation 1, the difference is:

[0054] In step 2), each cell is sucked up synchronously by the suction cup manipulator. The suction cup manipulator is equipped with multiple suction cups, which are arranged in sequence along the left and right directions, and each suction cup is at the same height; Suction cup spacing adjustment mechanism for each suction cup spacing, and each suction cup is also equipped with a turning mechanism; each suction cup picks up a cell, and the battery slice is rotated by a certain angle through the turning mechanism, and the adjacent two cells are reduced by the suction cup spacing adjustment mechanism. Cell spacing;

[0055] In step 3), the battery strings on the second carrier are heated and welded by a plurality of heating lamp tubes. The heating area of ​​the multiple heating lamp tubes covers the front connection of each battery. The front connection of the battery is the front edge electrode and The joint of the...

Abstract

The invention discloses a preparation method of a cell string, comprising the following steps: (1) arranging cells; (2) lapping a cell string; and (3) welding the cell string. The cutting efficiency of connecting pieces can be greatly improved, the cutting precision of the connecting pieces can be guaranteed, the lap joint efficiency of the cell string can be improved, the welding efficiency of the cell string can be improved, the preparation efficiency of the cell string can be improved, and the productivity of the cell string and a solar cell module can be improved.

Description

technical field [0001] The application belongs to the field of solar photovoltaic cells, and in particular relates to a method for preparing a battery string. Background technique [0002] The battery string is an important module in the solar cell module. The battery string is formed by connecting battery slices in series, and two adjacent battery slices in the battery string are connected in series through a small piece of connector, and the commonly used small piece of connector is generally a small piece of welding ribbon. [0003] At present, the preparation of battery strings is generally to cut off the welding ribbon piece by piece and overlap the battery pieces one by one. On the outer side of the battery slice, the next battery slice is overlapped on the small section of the welding ribbon, and so on, until the entire battery string is overlapped. It can be seen that every time a cell is overlapped, the ribbon needs to be cut once, so the ribbon needs to be cut mu...
