Abstract

The utility model provides a powder coating machine having two-stage horizontal preheating, which comprises a preheating device, a heating device, a powder coating device and a storage transmission device, wherein the two-stage preheating can be carried out to a material belt of an electronic component through the preheating device and the heating device. The preheated material belt is coated with powder at the powder coating device. The storage transmission device continuously supplies powder to the power coating device so as to maintain the liquid height of powder in a powder containing groove. The two-stage preheating device provided by the utility model can carry out preheating with different temperatures to the material belt of the electronic component. The lifting function is added to the heating device with high temperature so that the heating device and the material belt can be separated when the utility model stops, and thus, the falling of soldering tin caused by the continuous high temperature heating to the material belt can be avoided so as to enhance the quality of the material belt.

The specific embodiment

See also Fig. 1 to shown in Figure 3, powder coating machine with two sections horizontal preheatings of the present utility model mainly includes preheating device 1, heater 2, powder coating device 3 and storing conveying device 4, wherein preheating device 1 is the setting that is the level of state, but it has the inlet port 14 that feed strip 5 passes through and exports 15, be provided with heating tube 11 and number conveying running roller 12 in a heat-insulation layer 13 inside, but feed strip 5 is along carrying running roller 12 to be transferred preheating, 150 ℃～180 ℃ Celsius approximately of the preheat temperature of this preheating device 1, this temperature does not cause the melts soldering tin on the strip 5.

Strip 5 is after 1 preheating of process preheating device, the heater 2 that has high temperature heater (HTH) 21 in promptly entering, its heating-up temperature can be up to more than 250 ℃, by strip 5 temperature increase that will pass through, because this section heating process is short, though so therefore extreme temperatures in the heater 2, the strip 5 that passes through immediately also can enter powder coating device 3 immediately and be stained with and be coated with powder 6, make it surperficial scolding tin do not cause strip 5 to overstay the time in heater 2 and fuse.Be positioned at heater 2 belows and be provided with lowering or hoisting gear 22; once during Suspend Job; for avoiding heater 2 to continue built-in strip 5 is heated the scolding tin fusion that causes on the strip 5; therefore if when having stopped status to produce; then lowering or hoisting gear 22 is about to heater 2 declines; and strip 5 not being continued heating, the strip 5 that therefore is positioned at heater 2 is not influenced by shutdown and impaired.

See also Fig. 3 again to shown in Figure 5, for being loaded with for the powder 6 that is coated with electronic building brick on the filling band 5, this powder 6 can be delivered among the powder tank 31 by storing conveying device 4 in the powder coating device 3.Wherein storing conveying device 4 includes stock chest 41 and feeder channel 45, the powder 6 that is stored in the feeder channel 45 can be delivered in the stock chest 41 by supply carrier pipe 42, carry powder 6 to be delivered to powder tank 31 via spiral conveying tube 43 again, and accept by powder tank 31 set feeding mouths 311 through passage 44; Because strip 5 can continue to be stained with in operation process and be coated with powder 6 always, thus the storing conveying device 4 necessary powder 6 of constantly supplying with, make the quantitative powder 6 of tool in the powder tank 31, make strip 5 can attach powder 6 adequately and uniformly.

The continuous Fig. 3 that sees also, Fig. 5 and shown in Figure 6, above-mentioned powder coating device 3 has a powder tank 31, in powder tank 31, be provided with paddle 32, powder tank 31 both sides respectively are provided with delivery needle wheels 34, can drive strip 5 by being coated with powder 6 to be stained with in the powder tank 31, and be positioned at powder tank 31 sidepieces and be provided with flash outlet 312, when powder 6 gluts or paddle 32 in stirring powder 6 processes, can for unnecessary powder 6 thus flash outlet 312 overflow, the powder 6 that overflows can be delivered to stock chest 41 by overflow pipe 313, repeat again for using, when strip 5 passes through powder tank 31, the powder 6 that can will be placed in the powder tank 31 can reduce because of being stained with to be coated with, and also out-of-flatness of powder 6 liquid levels, agitating function that must be by paddle 32 makes powder 6 liquid levels in the powder tank 31 smooth and be easy to make strip 5 to be stained with to be coated with powder 6.

In addition, these powder tank 31 bottoms are provided with lifter 33, can adjust powder tank 31 high and low positions, pick action for the strip that passes through 5 as the best.

Via the powder coating machine that the utlity model has two sections horizontal preheatings to strip 5 through two sections preheatings, the stable powder coating device 3 that is coated with powder 6 and the storing conveying device 4 at regular time and quantity of being stained with is provided, these all are the work flows that can provide best in strip 5 coating process; Therefore the powder coating machine with two sections horizontal preheatings of the present utility model can be realized above-mentioned purpose and can reach described effect.The above only is preferred embodiment of the present utility model, and the equivalence that all personages who is familiar with skill of the present utility model make according to spirit of the present utility model is modified or changed, and all should be encompassed in the claimed claim of the utility model.
