Semi-automatic single welding machine for solar cell slices

Abstract

The invention relates to a semi-automatic single welding machine for solar cell slices, which comprises a rack, and is characterized in that: a welding strip fixing device, a welding strip alignment device, a feeding device, a flux coating device, a flux drying device, a welding strip cut-off device, and a welding strip traction device are sequentially arranged on the rack along the length direction, the welding strip cut-off device comprises a tool holder, a first compression device, a cutter and a welding head, and a chopping block is also arranged at the bottom of the tool holder; and the welding strip traction device comprises a second compression device capable of fixing welding strips, and a driving device capable of controlling the second compression device to move back and forth between a cut position and a welding position of each welding strip. According to the semi-automatic single welding machine for the solar cell slices, the fully manual operation is replaced to realize the semi-automatic single welding process for the solar cell slices, the overall structure is compact, the input cost is low, the working efficiency is improved, the labor is saved, the welding quality is ensured through the mechanized operation, and the needs of small and medium-sized photovoltaic enterprises for product upgrading can be better met. The semi-automatic single welding machine for the solar cell slices has broader market application prospects.

Description

technical field [0001] The invention relates to a welding machine equipment, in particular to a semi-automatic single welding machine for solar cells. Background technique [0002] In the prior art, one of the best ways to use solar energy is photovoltaic conversion (photovoltaic effect), which is to make sunlight irradiate on silicon materials to generate electric current to generate electricity directly. A power-generating device that generates electricity when exposed to sunlight, consisting of solid-state photovoltaic cells made almost entirely of semiconductor materials such as silicon, and can be used for a long time without causing any loss. [0003] The packaging technology of the module board is one of the key technologies of photovoltaic modules. In the packaging process of the module board, the positive and negative electrode welding is commonly known as single welding, which is a welding on the main grid line of the cell. Cover the flux and dry it, and then plac...

Problems solved by technology

[0004] At present, the single welding of solar cells is mainly completed by manual welding. Manual operation is used to ensure the positioning accuracy of welding and control the debris rate below 0.3%. Although the output can be guaranteed, the manual operation process cannot improve work efficiency. Moreover, The fully manual welding method has high requirements for the operator, and it is not easy to control the quality of the product

In addition, foreign countries have developed fully automatic welding equipment, such as the fully automatic welding machine produced by the German IMA company, the SL series welding machine produced by the Spanish GOROSABEL company, the TT1200 high-speed serial welding machine produced by the German Dime company, and the NTS produced by the Japanese NPC company. -150-STD automatic welding machine, etc. Although these automatic welding machines can realize automatic operation, but a piece of equipment costs several million, the input cost and maintenance cost are very high, and compared to such a high input cost, the output It has not necessarily been greatly improved, so for small and medium-sized enterprises in our country, such fully automatic welding equipment is not applicable
