Solder strip delivery mechanism of solar cell serial welding machine

Abstract

The invention discloses a solder strip delivery mechanism of a solar cell serial welding machine and solves the problems in the prior art that easy solder strip breakage and low welding strength are caused by the unreasonable structure of the delivery mechanism. The solder strip delivery mechanism comprises a W-shaped solder strip partition board (16), wherein the W-shaped solder strip partition board (16) is arranged at the bottom of a U-shaped framework (15), strip unwinding rotating shaft bearings (18) and strip unwinding rotating shafts (19) are respectively arranged on two vertical boards of the U-shaped framework (15), a pair of strip unwinding rotating rollers (20) are fixedly arranged on the strip unwinding rotating shafts (19), internally round steps (21) are arranged on the inner sides of the strip unwinding rotating rollers (20), a solder strip reel (23) wound with solder strips (13) is movably clamped between the two internally round steps (21) of the two strip unwinding rotating rollers (20), and reel edges (24) on the two sides of the solder strip reel (23) are connected with rubber rings (22) arranged on the internally round steps (21) in a sleeving way in a roll welding way. The solder strip delivery mechanism has the advantages of convenience in operation and simplicity in structure and is particularly suitable for being applied in the field of solar cell high-speed serial welding.

Description

technical field [0001] The invention relates to a solar cell stringer, in particular to a ribbon supply and delivery mechanism in the solar cell stringer. Background technique [0002] The solar cell stringer is a device that automatically strings together the positive and negative electrodes of multiple solar cells under the control of PLC, including a ribbon distribution mechanism, a soldering mechanism, a solar cell feeding mechanism, and a solar cell Positioning mechanism and automatic transfer welding carrier. Generally, a plurality of cell busbars are arranged on a solar cell, and a plurality of parallel ribbons need to be serially soldered to the plurality of busbars respectively. During the stringing process of solar cells, the transfer and separation of welding ribbons is a very important process. At present, the belt running method relies on mechanical pulling or pneumatic pulling, and the method of mechanically separating the welding belt is used to complete the...
