[0036] In this example, see Figures 4 to 6When in use, multiple portions of sintered flux are placed on the conveying component 5 at intervals. The conveying component 5 is started to convey the first portion of sintered flux to the drying chamber 12. The drying component 3 dries the sintered flux. After the drying is completed, the conveying component 5 is started again to convey the first portion of sintered flux to the cooling chamber 13. At this time, the second portion of sintered flux is located in the drying chamber 12, and the third portion of sintered flux is located in the pretreatment chamber 11. The drying component 3 dries the second portion of sintered flux, while the first portion of sintered flux is in the cooling chamber 13. A large amount of heat will be released during cooling. At this time, the cooling fan 4 is started to dissipate the heat of the first portion of sintered flux, and the hot air is transported to the pretreatment chamber 11 through the pipe 2. The hot air is used to pre-dry and preheat the third portion of sintered flux to reduce the humidity of the third portion of sintered flux, thereby improving the drying efficiency of the sintered flux. The present application can not only quickly cool the dried sintered flux, but also use the residual heat of the dried sintered flux to pre-treat the sintered flux to be dried, with high energy utilization rate, avoiding heat loss.

[0037] In this embodiment, the pretreatment chamber 11, the drying chamber 12 and the cooling chamber 13 are spaced apart along the first direction, the conveying direction of the conveying assembly 5 is also the first direction, a first air inlet is provided on one side wall of the pretreatment chamber 11 in the second direction, a first air outlet is provided on the top of the pretreatment chamber 11, and a third air inlet and a third air outlet are respectively provided on the two side walls of the cooling chamber 13 relatively arranged along the second direction. The cooling fan 4 is provided at the first air inlet for drawing outside air into the cooling chamber 13 to cool the sintered flux, and the two ends of the pipe 2 are respectively connected to the third air outlet and the first air inlet, so as to introduce the hot air in the cooling chamber 13 into the pretreatment chamber 11, wherein the first air inlet and the third air outlet are arranged on the same side.

The heating wire 32 is provided at the second air inlet for heating the air entering the drying chamber 12, thereby forming hot air to dry the sintered flux. The second air inlet and the third air inlet are provided on the same side.

[0040] In one embodiment, see Figure 5 and Figure 6 The sintering flux oven also includes a heat exchange tube 6, which is arranged in the pretreatment chamber 11. One end of the heat exchange tube 6 is connected to the drying chamber 12, and the other end of the heat exchange tube 6 extends out of the pretreatment chamber 11.

In order to avoid mutual interference between adjacent chambers, the feed port, the discharge port and the two conveying holes are each provided with a baffle 7, and the baffle 7 can open or close each chamber. In specific use, when conveying is required, the baffle 7 opens each chamber to facilitate the material to enter and exit each chamber. When the conveying is completed and drying is required, the baffle 7 closes each chamber to avoid mutual interference.

[0048] In one embodiment, see Figures 1 to 3 , the baffle 7 is movably arranged along the vertical direction.

[0049] In this embodiment, slots are provided at the feed port, the discharge port and the two conveying holes, and the slots extend upward to the upper side of the box body 1 to form an opening. The baffle 7 is slidably installed in each of the slots from the opening, so that when the baffle 7 slides upward, each chamber can be opened, and when the baffle 7 slides downward until it abuts against the conveying component 5, each chamber can be closed.

[0050] In one embodiment, see Figures 2 to 4 The sintering flux oven further includes a driving assembly 8, which is connected to the plurality of baffles 7 to drive the plurality of baffles 7 to move synchronously.

[0051] In this embodiment, since the plurality of baffles 7 need to be opened and closed simultaneously, the driving assembly 8 may be provided to be connected to the plurality of baffles 7 , so that the plurality of baffles 7 are driven to move synchronously by the driving assembly 8 .

[0052] In one embodiment, see Figures 2 to 4The driving assembly 8 includes a connecting member 81, a screw rod 82 and a driving motor 83.

[0057] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0058] When in use, multiple portions of sintered flux are placed on the conveying assembly 5 at intervals. The conveying assembly 5 is started to convey the first portion of sintered flux to the drying chamber 12. The drying assembly 3 dries the sintered flux.

At this time, the second portion of sintered flux is located in the drying chamber 12, and the third portion of sintered flux is located in the pretreatment chamber 11. The drying assembly 3 dries the second portion of sintered flux and conveys high-temperature and high-humidity air to the heat exchange tube 6.
