Problems solved by technology
[0004] 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 efficiency of ribbon cutting, and at the same time causes the structure of the ribbon shearing mechanism to be complicated and costly
[0005] 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
[0006] 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

The invention discloses a welding-strip feeding mechanism and method and a string welding machine. The welding-strip feeding mechanism comprises a movable frame and a pressing assembly. The movable frame is movably arranged on a welding-strip cutting table and connected with a feeding driving device, and the feeding driving device drives the movable frame to reciprocate along the welding-strip cutting table. The pressing assembly is arranged on the movable frame, and a to-be-cut welding strip is tightly pressed to the movable frame through the pressing assembly. According to the welding-strip feeding mechanism and method and the string welding machine, the welding-strip feeding mechanism is additionally arranged at the station in front of a welding-strip cutting mechanism, and the to-be-cut welding strip is tightly pressed to the movable frame and fed through the movable frame. The welding-strip cutting efficiency is improved, welding-strip feeding accuracy is high, and the welding quality of the string welding machine is guaranteed.
Description
technical field [0001] The invention relates to the welding technology of solar cells, in particular to a welding belt feeding mechanism, a feeding method and a string welding machine for a string welding machine. Background technique [0002] In order to produce solar cell modules, for example, to be installed on roofs for solar power generation, usually several solar cells with interconnecting sheets are connected in series. The interconnecting sheets of adjacent solar cells are respectively connected with the interconnecting sheets by means of soldering tapes or soldering tape segments. Typically the ribbon is tinned copper and is connected to the interconnect via one or more solder joints. A solar cell may have multiple interconnects, ranging from one to three at most, requiring an equal number of ribbon segments to form a series group. The mechanism that processes this solar cell series group is called a stringer. [0003] Stringers used to string together solar cell...
