Abstract
The invention discloses a simulation assembly of a photovoltaic assembly and a manufacturing method of a welding tension sample of a junction box and a bus bar, which belong to the technical field of solar cells. The method is used for solving the problems that in the prior art, manual installation of a junction box and a bus bar is large in operation difficulty and long in time consumption, and a welding tension sample of the junction box and the bus bar is detached from a photovoltaic module, so that the quality of part of the photovoltaic module is abnormal. The simulation assembly comprises a sliding rail,at least one group of sliding blocks and at least one group of bus bars, wherein the at least one group of sliding blocks are connected with the sliding rails in a sliding manner, the number of the sliding blocks in each group is two, and the sliding blocks are provided with mounting grooves; the number of the bus bars in each group is two, one part of each bus bar detachably extends into the corresponding mounting groove, and the other part of each bus bar is exposed out of the corresponding sliding block and the corresponding sliding rail and is used for being connected with a junction box in a welded mode. By the adoption of the simulation assembly and the manufacturing method of the welding tension sample of the junction box and the bus bar, the welding tension sample of the junction box and the bus bar can be rapidly manufactured, and the application range is wide.
Description
technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a simulation module of a photovoltaic module and a method for making a welding tensile sample of a junction box and a bus bar. Background technique [0002] During the production process of photovoltaic modules, it is necessary to weld the junction box and the bus bar of the photovoltaic module to output the current inside the photovoltaic module. In order to prevent hidden dangers such as false welding and burning of the junction box caused by unqualified welding tension in batches, the junction box and bus bar can be welded to form a welding tension sample, and then the welding tension sample is tested to monitor the welding quality. [0003] At present, the production of welding tensile samples usually uses the automatic welding machine of the junction box to realize the welding of the junction box and the bus bar of the photovoltaic module. [0004] However, ...
