Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Shown in Fig. 1, it is the equipment flowsheet that utilizes the shielding process that hot-melt model capable tearing coating carries out before a kind of electroplating assembly line is electroplated.Shielding device comprises: workpiece is carried out to pre-warmed preheating furnace 3, and preheating furnace 3 is connected with steeping vat 6 by carrier chain, and steeping vat 6 tops are provided with mends glue groove 7; Steeping vat 6 is connected with levelling chamber 9 by carrier chain, and levelling chamber 9 must process chamber 12 be connected with hanging, and hangs and must be connected water-cooling groove 11 and be dewatered except moist chamber 8 by transport tape successively by process chamber 12, dewaters and is connected with lower frame except moist chamber 8.
In present device, preheating furnace 3 is communicated with vapor heat exchanger 1 by circulating fan 2, steeping vat 6 is communicated with heat transfer oil filter 4 by thermal medium circulating pump 5, levelling chamber 9 is communicated with air cooling system 10, hang and must be communicated with air-heater 13 by process chamber 12, water-cooling groove 11 is connected with the return piping and the water supply line that dewater except moist chamber 8 respectively.
