Description

Single-furnace type vacuum coating equipment Technical Field The utility model relates to the technical field of coating equipment, in particular to single-furnace vacuum coating equipment. Background The vacuum coating equipment comprises a decorative coating and a functional coating, wherein the vacuum coating equipment comprises two types, namely a single furnace type coating and a continuous type coating, the cavity of the continuous type coating equipment is always in a vacuum state, and the energy consumption of a vacuum pump is low, but the vacuum coating equipment is only suitable for mass production with a single process, and the coating process is inconvenient and flexible to convert, so that the function of small-batch customization or color coating can be realized. The single furnace type has the characteristic of flexibility, and is combined with the characteristic shown in fig. 1, the coating cavity 1 needs to be repeatedly inflated and vacuumized to replace and mount a coated workpiece during production, the vacuumized energy consumption is high, the time is needed to vacuumize again after new workpieces are put in each time, after the coating cavity 1 is coated in a previous batch, the inflation valve 100 inflates the coating cavity 1, then the cavity door or the upper cover is opened, the coated workpiece and the new workpiece to be coated are taken out, the cavity door or the upper cover is closed, the rotary vane pump in the rough pump group 30 is started firstly, the rough pump 130 is opened to vacuumize the coating cavity 1, the Roots pump in the rough pump group 30 is started to accelerate the extraction of low vacuum when the vacuum degree in the coating cavity 1 reaches 900Pa, the rough pump group 130 is closed, then the backing valve 310 and the fine pump 140 are opened in sequence, at the moment, the rough pump group 30 is used as the backing of the high vacuum pump 40, the high vacuum pump 40 is used for pumping the background vacuum (usually 0.02Pa or higher) required by the coating, the required process can be started after the background vacuum is achieved, the refined pumping valve 140 and the vacuum pumps at all levels are sequentially closed after the coating is completed, the inflation valve 100 is opened to completely fill the coating cavity 1 with air, the cavity door or the upper cover is opened again to mount workpieces, according to the above flow, the negative pressure of each batch of high vacuum pumped to the coating cavity 1 is completely released after the coating is completed, in addition, in the process of gradually pumping, the time for switching the refined pumping valve 140 from about 100000Pa to 2Pa in the process of gradually pumping is often required to be longer, so that the productivity of the equipment cannot be improved no matter whether the energy consumption of re-pumping is needed or the time for waiting for pumping is required to be improved, and the improvement is required. The overall production efficiency is relatively low compared to continuous production.
