Description

A ribbon feeding mechanism and stringer

technical field

The utility model relates to the welding technology of solar cells, in particular to a welding strip feeding mechanism and a stringer for a stringer.

Background technique

In order to produce solar cell modules, for example, to be installed on roofs for solar power generation, usually several solar cells with interconnected tabs are connected in series. The interconnection sheets of adjacent solar cells are connected to each other by means of welding strips or sections of welding strips. Usually the ribbon is tinned copper and is connected to the interconnect by one or more solder joints. A solar cell may have multiple interconnects, one to three at most, requiring an equal number of ribbon segments to form a series connection. The mechanism for processing this series of solar cells is called a stringer.

Stringers used to string solar cells together typically include a feed table for feeding the solar cells and the continuous strip of ribbon. Ribbon strips are usually continuously unwound from a ribbon reel, which is also fixed on a feeding table. Each interconnect tab on each solar cell corresponds to a continuous strip of solder ribbon. After the ribbon is continuously unwound, it is conveyed to a cutting station where it is divided into individual ribbon segments. At present, the existing ribbon cutting mechanism for stringers generally includes a ribbon shearing mechanism and a clamping mechanism. The ribbon shearing mechanism is arranged at the front station of the clamping mechanism. After moving a certain distance, the ribbon is cut by the ribbon shearing mechanism. This form of ribbon cutting mechanism has the following disadvantages in the specific application process:

1) The upper and lower knives of the ribbon shearing mechanism must move at the same time to complete the shearing of the ribbon, which affects the ribbon cutting efficiency, and at the same time causes the ribbon shearing mechanism to have a complex structure and high cost.

2) The feeding of the welding ribbon is only realized by the traction of the clamping mechanism, resulting in a large pulling stroke of the welding ribbon, and the clamping mechanism must perform clamping after the upper and lower knives of the welding ribbon shearing mechanism give way, and the overall Affect the ribbon cutting efficiency.

3) After the upper and lower knives of the ribbon shearing mechanism cut the ribbon, the head of the ribbon is prone to offset, and the overall position of the ribbon is offset after the clamping mechanism clamps it, resulting in offset of the welding position of the subsequent ribbon , affecting the welding quality of solar cell modules.
