BMC line spraying system and spraying process

Abstract

The invention relates to the field of automatic spraying, in particular to a BMC line spraying system and spraying process. The system comprises a feeding station used for feeding of products obtainedafter injection molding, a preliminary trimming station used for carrying out preliminary trimming on the products, a fine trimming station used for carrying out secondary trimming on the products, adust removal station used for carrying out dust removal on the products obtained after trimming, a UV pretreatment station used for carrying out UV pretreatment on the products obtained after dust removal, a paint spraying station used for carrying out paint spraying on the products obtained after UV pretreatment, a buffer leveling station used for carrying out buffer leveling on the products obtained after paint spraying, a UV curing station used for carrying out UV curing on the products obtained after buffer leveling and a discharging station used for cooling and discharging the products obtained after UV curing. The system further comprises a control station used for control. The BMC line spraying system and spraying process are low in manpower dependency degree, high in automation degree and working efficiency, good in spraying quality, high in product percent of pass and small in occupied area.

Description

technical field [0001] The invention relates to the field of automatic spraying, in particular to a BMC line spraying system and a spraying process thereof. Background technique [0002] BMC material is the abbreviation of Bulk molding compounds, that is, bulk molding compound. It is often called unsaturated polyester bulk molding compound in China. Its main raw materials are GF (chopped glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives that are fully mixed into a dough-like prepreg. DMC materials were first applied in the former West Germany and the United Kingdom in the 1960s, and then developed in the United States and Japan in the 1970s and 1980s. Because BMC bulk molding compound has excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and adapts to various molding processes, it can meet the performance requirements of various products, so it is more and more popular among users...

AI Technical Summary

Problems solved by technology

[0004] The whole painting process includes pick-up, powder layer treatment, UV treatment, cooling, etc. On the one hand, in the BMC line spraying process of the prior art, products are transferred manually between stations, which has high labor costs and high work efficiency. On the one hand, the powder layer is processed directly after injection molding on the mold. Since the directly formed product will have burrs and other defects, direct spraying will result in low spraying quality and low product qualification rate. Thirdly, there are too many manual operations The space layout is unreasonable and the floor area is large
