Flat welding strip pre-welding rotary table welding device

Abstract

The invention discloses a flat welding strip pre-welding rotary table welding device, and relates to the technical field of photovoltaic module production. The flat welding strip pre-welding rotary table welding device comprises a rotary table, a first station, a second station, a third station, a fourth station, a pressing mechanism, a welding strip positioning structure and a welding strip pre-welding mechanism, wherein the rotary table is used for controlling the conversion of the welding strip positioning structure; welding tables, positioning clamps and positioning blocks are arranged on the rotary table of all the stations, and air suction structures are arranged on the welding tables; the pressing mechanism is used for pressing the welding strip positioning structure, and the pressing mechanism is located on a support tool of a rotating shaft; the welding strip positioning structure is used for positioning a battery piece; and the welding strip pre-welding mechanism comprises a heating block, cylindrical pressing needles, a first guide rail and a lifting driving mechanism, the cylindrical pressing needles are installed in the heating block, the heating block is connected to the first guide rail in a sliding mode, and the heating block is connected to the lifting driving mechanism. The device has the following beneficial effects that (1) the efficiency and the productivity of the device are greatly improved; (2) the operation is convenient and stable; and (3) the welding strip is good in lap joint effect and not prone to dislocation.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module production, in particular to a flat welding strip pre-welding turntable welding device. Background technique [0002] As a low-carbon renewable energy source, solar energy is convenient and low-cost compared with conventional energy sources. Solar photovoltaic modules are used to directly convert solar energy into electrical energy, supply power to electrical equipment or transmit electrical energy to the grid. The solar panel is spliced ​​by battery sheets, and the electrodes of two adjacent battery sheets are connected, and the two adjacent battery sheets need to be welded by welding tape. [0003] The previous welding method is to put the front ribbon first, then put the battery on the back, because there is a sequential process relationship between the ribbon and the battery, and this relationship requires a certain amount of production capacity to achieve high efficiency. For th...
