A bus bar welding machine head

Abstract

The invention discloses an improved bus bar welding machine head. The improved bus bar welding machine head comprises an anode main supporting plate, welding assemblies, connecting assemblies, liftingassemblies and an electrode copper plate assembly, wherein each welding assembly is movably fixed to the front plate surface of the anode main supporting plate in a liftable manner through one connecting assembly and one lifting assembly; and the electrode copper plate assembly provides a welding current for the welding assemblies. According to the invention, the improved bus bar welding machinehead comprises the multiple welding assemblies, each welding assembly comprises a plurality of welding heads, and welding efficiency is greatly improved; the positive and negative welding heads adoptup-down alignment welding, the welding heads and welding bars are in continuous long-line contact, the situation that the welding heads and the welding bars are in poor contact as the welding bars aretoo short is avoided, and welding quality is guaranteed; and the positions of the welding heads in the welding machine head can be changed, so that the welding machine head can adapt to welding of bur bars of various specifications, lifting operation of the welding assemblies in welding operation can be independently controlled by the lifting assembles, and welding flexibility is further improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy equipment, in particular to a bus bar welding head. Background technique [0002] Since the 21st century, the world is facing new challenges, among which the global non-renewable energy storage is decreasing and the environmental pollution caused by energy combustion is becoming more and more serious. The sustainable use of energy and environmental protection have become the focus of global attention, restricting the economy. Steady political development. Solar energy is a renewable green energy. Countries are committed to the conversion and utilization of solar energy. The market prospect of solar photovoltaic power generation is broad. Solar panels are the most basic components of photovoltaic power generation systems / products and the core of solar photovoltaic power generation systems. part. Its biggest function is to convert solar energy into electrical energy and store it in the batter...

Problems solved by technology

In the process of manufacturing and assembling crystalline silicon solar cell modules, multiple solar cells must be welded into solar cell strings with welding rods first, and then the welding rods extending from the two ends of the multiple solar cell strings must be connected to the confluence of the two sides of the solar panel. The strips are welded together, and the current is collected by the electrode. Traditional welding is usually done manually by the operator. The welding efficiency is low and the operation error rate is high, resulting in an increase in the scrap rate. Now there are more automatic welding machines for bus bar resistance welding. But because the number of welding rods on a cell is different and the total welding points of the bus bar and the electrodes at both ends are different, the bus bar automatic welding machine in the prior art cannot meet the bus bar welding of solar panels with various specifications. The degree of specialization It is relatively high, and cannot be flexibly modified according to different bus bar welding conditions. If you purchase a variety of bus bar welding equipment, it will increase the bus bar welding cost

[0004] Secondly, when the length of the electrode extending from the two ends of the bus bar is short, the contact between the welding head and the two ends of the electrode is unstable, it is difficult to fully contact, and the welding quality is difficult to guarantee
