The technical scheme of the utility model is: a new type of air inlet device for the dryer, including an upper air inlet device and a lower air inlet device, the upper air inlet device is arranged at the upper end of the furnace body, and the lower air inlet device is arranged at the bottom of the furnace body The lower end, the upper air inlet device includes an upper air inlet, the first air inlet pipe, the upper air inlet is located at the upper end of the body of furnace, the upper air inlet is connected with the first air inlet pipe, and the lower air inlet device includes a lower air inlet, The drying fan and the second air inlet pipe, the lower end of the furnace body is provided with several lower air inlets, the other ends of the lower air inlets are connected to the connecting pipe, the second air inlet pipe is connected to the middle air hole of the connecting pipe The first air inlet pipe is connected with the upper air hole of the second air inlet pipe, the other end of the second air inlet pipe is connected with the drying fan, the upper end of the furnace body cavity is provided with a heating lamp, and the upper end of the furnace body An air outlet is also provided, the inner wall of the air outlet is provided with an oil filter, the air outlet is connected to the exhaust fan through a pipeline, the inlet and outlet of the furnace body are provided with air curtains, and the outer wall of the outlet of the furnace body is Features a blow dryer.

Further, a heat insulation board is provided on the inner wall of the furnace body.

Further, the quartz plate for placing the silicon wafer is provided with two baffles along the conveying direction of the silicon wafer.

Further, the baffle is located at the front and rear ends of the quartz plate.

The advantages and positive effects of the utility model are: due to the adoption of the above-mentioned technical scheme, the upper and lower air inlet devices are provided, so that the upper and lower sides of the silicon wafer can be dried conveniently, and the aluminum paste and silver paste on the surface of the silicon wafer can be completely dried. The slurry is dried; there is an oil filter on the inner wall of the air outlet, which prevents the gas in the air outlet from sometimes dripping onto the dried silicon wafer due to the oily liquid, which improves the quality of the silicon wafer.

Detailed ways

As shown in Figure 1-3,

The technical scheme of the utility model is: a new type of air inlet device for a dryer, including an upper air inlet device and a lower air inlet device, the upper air inlet device is arranged at the upper end of the furnace body 1, and the lower air inlet device is arranged at the furnace body 1, the upper air inlet device includes an upper air inlet 2 and a first air inlet pipe 3, the upper air inlet 2 is arranged on the upper end of the furnace body 1, the upper air inlet 2 is connected with the first air inlet pipe 3, and the lower air inlet The wind device comprises a lower air inlet 4, a drying blower fan 5 and a second air inlet pipe 6. The lower end of the body of heater 1 is provided with several lower air inlets 4, and the other end of the lower air inlet 4 is connected to the connecting pipe. 7, the second air inlet pipe 6 is connected to the middle air hole 8 of the connecting pipe 7, the first air inlet pipe 3 is connected to the upper air hole 9 of the second air inlet pipe 6, and the other air inlet pipe 6 of the second air inlet pipe 6 is connected to each other. One end is connected with the drying blower 5, the upper end of the inner cavity of the furnace body 1 is provided with a heating lamp 10, the upper end of the furnace body 1 is also provided with an air outlet 11, the inner wall of the air outlet 11 is provided with an oil filter 12, and the outlet The air port 11 is connected to the exhaust fan through a pipeline.
