Embodiment Construction

[0016] Such as Figure 1-3 Shown, a kind of cleaning method of thin-film solar cell bus bar welding head, it comprises the following steps: Step 1: on the soldering seat 2 below welding head 1, a size is set: thickness 3mm, width: 100mm, long 200mm bus bar A metal plate 3 made of pure aluminum with the same material properties and hardness;

[0017] Step 2: Select the cleaning process parameters. The cleaning process parameters are different from the normal production process parameters. Generally, the amplitude percentage of the welding head will be increased by 50%. The significance of the amplitude percentage parameter is to control the stroke of the tooth-shaped welding part 101 of the welding head. The large pieces of debris 1a are easily and quickly compatible with the metal plate 3 under high-frequency friction, so that the metal plate 3 can capture the large pieces of debris 1a on the toothed welding portion 101 of the welding head, thereby reaching the point of preli...

Abstract

The invention provides a cleaning method of a thin-film solar cell bus bar welding joint. The cleaning method of the thin film solar cell bus bar welding joint is characterized by comprising the following steps of arranging a metal plate below the welding joint, directly welding on the metal plate, and then coating acid on the welding joint. The cleaning method of the thin film solar cell bus bar welding joint is simple in step and convenient to operate, and the welding joint does not need to be disassembled during cleaning, so that operation technical difficulty is reduced, and the influence of a cleaning method in the prior art on equipment machining stability is avoided.

Description

Technical field: [0001] The invention relates to the technical field of welding device cleaning, in particular to a method for cleaning a welding joint of a thin-film solar battery bus bar. Background technique: [0002] Photovoltaic power generation is an efficient and clean energy utilization method in today's society. As of the end of 2018, the cumulative installed capacity of photovoltaic modules in the world exceeded 510GW. As the world's energy crisis and environmental pollution become more and more serious, people have accelerated the research on solar photovoltaic power generation technology, so the solar cell manufacturing technology has achieved rapid development. Among them, thin-film solar cells are the central branch of the solar cell field. Years of rapid development. [0003] In the production process of thin-film solar cells, after the preparation and segmentation of the photoelectric conversion functional layer is completed, it is necessary to install a dr...
