The lamp of one circle warms up unit and is directed at the second loading box for toasting to the circuit board in the second loading box.When only a small amount of electricity
When road plate needs to toast, as shown in Fig. 2, being linked with circuit board below turntable, turntable is lighter at this time, multiple second loading boxes position
Unit is warmed up in above one circle lamp and following circle lamp warms up between unit, so that the lamp of two circles, which warms up unit, to carry out circuit board
Baking, and round iron plate falls at this time, abuts the second non-slip mat, and round iron plate and bellows are each coated with reflective painting
Layer, to actually reduce the intracorporal space of case, so that heat waste reduces, heat is all used for the baking to circuit board,
Rotation due to being provided with second bearing, turntable will not influence round circuit board, so that baking is more energy saving, efficient.In order to keep away
Exempt from the influence of air pressure, air hole, the diameter very little of air hole, such as 1mm can be offered at iron plate.To which round iron plate exists
When mobile, the influence of air pressure is avoided, and the air hole of very little will not thermally conductive heat waste.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
