Embodiment 1

[0049] Such as Figure 1 to Figure 4 , a welding ribbon correction mechanism, the structure includes: a fixture 1, which can open and close in opposite directions, and its function is to straighten the welding ribbon to the bus bar of the battery sheet, and a spring 4 arranged at the upper opening of the fixture, which The function is to control the closing of the clamp, the clamp 1 passes through the clamp seat 1-2, the middle part of the clamp is connected with the clamp seat through the pin shaft 1-3, and the middle position of the middle and lower part of the clamp seat is provided with a clamp seat protrusion 1-2 4. The driving device 2, the fixture driving plate 3 connected to the output end of the driving device, the lower part of the driving plate is provided with an inverted "V"-shaped opening, and the inverted "V"-shaped opening is connected tangentially to the upper part of the fixture, driving The plate moves up and down under the driving force of the driving devic...

Embodiment 2

[0051] Such as Figure 14 As shown, this embodiment provides a clamp for a welding ribbon correction mechanism. The number of the clamp and the welding ribbon is 11. The initial state of the clamp is an opening. Move closer to the ribbon and gradually reduce the opening angle until the ribbon is straightened to the bus bar of the cell.

Embodiment 3

[0053] Such as Figure 15 As shown, this embodiment provides a clamp for the welding ribbon correction mechanism, the number of the clamp and the welding ribbon is 11, the initial state of the clamp is closed, and when the welding ribbon is corrected, two The clamp moves closer to the solder strip from the direction away from the solder strip and gradually opens the opening until two adjacent clamps straighten the solder strip to the main grid line of the cell.

Abstract

The technical solution provided by the invention is mainly used to solve the technical problems that the welding ribbon and the main grid line cannot be completely aligned and the welding ribbon at the end of the battery sheet is twisted when the existing equipment welds the ribbon on the busbar of the cell. The invention proposes a stringer, which is equipped with a ribbon correction mechanism, which is used to straighten the ribbon at the end of the cell before welding the ribbon, and at the same time adjust the position of the ribbon so that it is aligned with the battery Align the main grid lines to ensure that the welding points of the main grid lines at the first end of the cell are aligned, and ensure the quality of interconnection and welding between the cell and the ribbon.

Description

technical field [0001] The invention relates to the technical field of welding ribbons on solar cells, in particular to a rectification mechanism and a stringer for soldering ribbons on the main grid of solar cells near the ribbon end of the ribbon. Background technique [0002] In the process of using automatic equipment for solar cell series welding, there are always various technical problems in the automatic technology of interconnection welding of solar cells and ribbons. At present, 10 grids and 12 grids are used in the market. Cells and 0.4mm circular ribbons, due to the increase in the number of busbars on the solar cells, the busbars on the solar cells are thinner and denser, so the corresponding connecting ribbons are also very thin. The disadvantages are even more obvious. For example, the date of authorization announcement is June 5, 2013, the application number is 201220617765.6, and the patent name is "welding ribbon and cell pressing device for solar cell ser...
