Problems solved by technology
Therefore, this welding equipment and method has certain limitations: ① There are many repeated steps in the welding of a string of battery strings, the welding time is long, and the welding efficiency is low; The larger the area of the photovoltaic module, the lower the conversion efficiency
③ The stress generated by the Z-bending of the ribbon on the edge of the photovoltaic cell can easily lead to fragmentation and failure of the photovoltaic cell during the manufacturing process, limiting the research and application of photovoltaic cell thinning
The above limitations of welding have become a technical bottleneck in the development of splicing components and a major obstacle to the development of high-efficiency components

The invention discloses a series welding device and a double-sided battery piece series welding method. The series welding device comprises conveying platforms, a transverse mechanical device and a series welding platform, wherein the transverse mechanical device is used for transferring all double-sided battery pieces on the third conveying platform to the first conveying platform at a time, and transferring all sub welding strips on the second conveying platform to the first conveying platform at a time to obtain a combined structure of the sub welding strips and the double-sided battery pieces; and the series welding platform is used for welding the combined structure of the sub welding strips and the double-sided battery pieces to obtain a battery string. According to the technical scheme provided by the invention, a plurality of welding strips and battery pieces can be grabbed and moved at a time, so that the grabbing frequency is reduced to the maximum extent, and the series welding efficiency of the battery pieces is greatly improved; and the welding strips do not need to be bent, so that the problems that the distance between the battery pieces is large and the conversion efficiency is lower due to bending of the welding strips are solved, the risk that the battery pieces are broken and lose efficacy is reduced, and the conversion efficiency of the assembly is improved.
Description
technical field [0001] The invention relates to the field of intelligent equipment, in particular to a stringing device and a double-sided cell stringing method. Background technique [0002] With the promotion of photovoltaic power generation applications, the iterative speed of photovoltaic technology updates is also gradually accelerating. In terms of batteries, double-sided PERC (Passivated Emitter Rear Contact, PERC for short) has become the mainstream technology in the market, and TOPcon and HIT batteries are also rapidly developing industrial layouts; in terms of components, multi-busbar Half-cut components have been accepted and recognized by the market. New high-efficiency component technologies such as laminated components and spliced components are affected by the bottleneck of related material string welding equipment and welding methods, which limits the layout and development of further industrialization. [0003] At present, the mainstream welding equipment...
