A kind of l-c shape bus bar automatic preparation device and bus bar preparation method thereof

Abstract

The invention discloses an automatic preparation device of an L-C-shaped bus bar and a bus bar preparation method thereof. A half-plate type solar battery pack needs to use two bus bars of an L shapeand a C shape in the process of welding; existing L-shaped and C-shaped busbars are mostly obtained by manual bending. The automatic preparation device comprises a preparation frame, a material pulling mechanism, a bending installation guide rail, a CL type welding rod bending mechanism, a material moving mechanism and a feeding straightening mechanism. The material pulling mechanism comprises a material pulling guide rail, a bus bar rail, a material pulling sliding block, a bidirectional clamping component and a material pulling driving component. The CL type welding rod bending mechanism comprises a C-type bending seat, an L-type bending seat, a welding strip aligning component and three bending executing pieces. According to the cooperative matching of the material moving mechanism, thematerial pulling mechanism, the CL type welding rod bending mechanism and the feeding straightening mechanism, the full-automatic continuous production of the straight bus bar, the L-shaped bus bar and the C-shaped bus bar can be achieved. The automatic preparation device of the L-C-shaped bus bar and the bus bar preparation method thereof have small damage to the insulating layer on the weldingbelt and cannot generate long-distance grinding marks.

Description

technical field [0001] The invention belongs to the technical field of bus bar preparation, and in particular relates to an automatic L-C bus bar preparation device and a bus bar preparation method thereof. Background technique [0002] During the production process of solar photovoltaic modules, multiple sets of battery strings need to be connected and welded together. In recent years, with the continuous deepening of research on solar photovoltaic high-efficiency cells, half-chip technology has gradually evolved from the original full-chip technology. The half-chip is to divide the whole battery into two, and then weld it into a battery string. Compared with the whole module, the half module has lower internal loss, improved output efficiency, reduced hot spot effect and many other favorable factors, so it is highly sought after in the industry. The advancement of technology will inevitably lead to the change of corresponding production technology. [0003] Half-cut sol...

Problems solved by technology

[0003] Half-cut solar battery packs need to use L-shaped and C-shaped bus bars in the process of bus welding; most of the existing L-shaped and C-shaped bus bars are obtained by manual bending; in this way, L-shaped and C-shaped bus bars are prepared. The efficiency of the method is low, and the quality cannot be guaranteed
