Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production equipment, and in particular to a purging and smoothing device. Background Art

[0002] During the production and packaging of photovoltaic modules, a packaging film is often laid on the cover or back panel first, such as an EVA layer (ethylene-vinyl acetate copolymer), and then the battery string is placed on the EVA layer. When the EVA layer is bulging or there are foreign objects on it, it often causes the battery string placement position to bulge, resulting in abnormalities in subsequent visual photography or laminating machine pressing process, affecting the normal production and packaging of photovoltaic modules.

[0003] When bulges appear on the EVA layer or foreign matter is present on the surface, manual intervention is currently required to handle the problem. The efficiency of eliminating abnormalities is low, resulting in high production costs and low production efficiency for the overall photovoltaic module production. Utility Model Content

The pressing wheel 351 is elastically connected to the buffer fixing seat 352 through the connecting frame 353. During the process of the blowing component 33 purging the film, the film can be pressed down and fixed, so as to avoid relative movement and dislocation between the film and the packaging board 4, and to avoid the impact of the packaging board 4 with the film laid on it on the device carrying platform 32 during the conveying process, and to avoid the generation of vibration and noise. The blowing assembly 33 includes a first wind knife group 331, a second wind knife group 332 and a third wind knife group 333.

By blowing, foreign matter on the film can be blown away, and the smoothing and cleaning of the film can be completed automatically and efficiently. When the packaging board 4 with the film laid that has been purged and smoothed flows out of the conveying device 1 from the packaging board 4 output side B of the purging and smoothing device, the lifting mechanism 34 is controlled to make the device carrier platform 32 rise and return to its position, and wait for the next packaging board 4 with the film laid to be input from the packaging board input side A of the purging and smoothing device, and then repeat the operation from the beginning.
