[0038] The collecting mechanism 8 includes a fixed shell 82, which is provided with two groups, and the outer wall of each group of fixed shells 82 is fixedly connected with a square tube 81, the inner wall of the fixed shell 82 is slidably connected with a draw box 83, and there is a height difference between the draw box 83 and the fixed shell 82, so that the draw box 83 can be drawn out of the fixed shell 82, and the inner wall of the draw box 83 is fixedly connected with a partition 84, and the partition 84 is fixed at the middle of the height of the draw box 83. A leakage groove 85 is opened in the wall of the partition 84, and a linear array is formed along the outer wall of the partition 84. The top of the square tube 81 is fixedly connected to the inner wall of the lower shell 4.

[0039] Working principle:

[0040] When in use, the frame 1 is placed on the ground, and the circuit board enters the drying mechanism 3 from the slide rail 2. The drying mechanism 3 is fixed to the frame 1 through the frame 7. The slide rail 2 is provided with a pulley to reduce the friction between the circuit board and the slide rail 2. The two sets of slide rails 2 on the frame 1 can not only assist the sliding of the circuit board but also limit the sliding trajectory of the circuit board, thereby limiting the sliding direction of the circuit board. When the circuit board passes through the drying mechanism 3, the drying mechanism 3 can dry the circuit board. After the drying mechanism 3 dries the circuit board, the components on the circuit board may have cold solder joints during welding, causing the components to fall off. Therefore, the liquid blown off the surface of the circuit board and the components are suspended on the lower shell 4, and then slide into the collecting mechanism 8. The collecting mechanism 8 performs static separation and filtration on the liquid and the components, and then the next step of centralized processing can be carried out.

[0041] Before drying the circuit board, it is necessary to first energize the heating wire 37 to generate heat, then turn on the stepper motor 6, so that the stepper motor 6 drives the fan blade 35 to rotate through the rotating shaft 36, and blows the air on the top of the heating wire 37 to the bottom of the heating wire 37. The rotating shaft 36 is fixed to the shield 33 through the connecting frame 34 to maintain the stable rotation of the rotating shaft 36. After the heating wire 37 and the stepper motor 6 are prepared, the circuit board is manually placed on the slide rail 2, and then the circuit board is slowly pushed so that the circuit board slowly passes through the drying mechanism 3.

[0042] When the circuit board slowly enters between the upper shell 31 and the lower shell 4, the hot air at the top of the heating wire 37 is forced to move to the bottom of the heating wire 37 under the rotation of the fan blade 35. When the hot air passes through the diverter cover 38, it is divided into two air flows. One air flow directly passes through the diverter cover 38 and blows to the surface of the circuit board, while the other air flow passes through the diverter groove 39 and moves along the upper shell 31 to the lower shell 4. The air flow is gathered by the guide ring 5 and moves upward to the bottom of the circuit board, thereby drying the upper and lower surfaces of the circuit board at the same time. After the airflow to the bottom of the circuit board passes through the obstruction of the circuit board, it diffuses around the circuit board. Because the hot air moves upward, the hot air continues to move to the vicinity of the upper shell 31, but the upper shell 31 is connected to the shield 33 through the air pipe 32. Therefore, under the rotation of the fan blade 35, the air moving around the upper shell 31 is forced to be sucked into the air pipe 32, and then moves from the air pipe 32 to the shield 33, so that the air still has heat is heated by the electric heating wire 37 again and continues to be blown onto the circuit board, thereby accelerating the drying of the circuit board.

[0043] The collecting mechanism 8 in the lower shell 4 can collect and separate the liquid and parts blown off by the drying mechanism 3 for centralized treatment. After the liquid and parts fall into the lower shell 4, a notch is provided on the square tube 81, so the parts larger than the notch continue to remain in the lower shell 4, while the parts smaller than the notch move to the fixed shell 82 through the square tube 81, and under the airflow of the drying mechanism 3, the airflow pushes the parts to move into the fixed shell 82, and a draw box 83 is provided in the fixed shell 82, and a partition 84 is fixed in the draw box 83, and a leakage groove 85 is provided in the partition 84, so the parts larger than the leakage groove 85 fall onto the partition 84, and the parts smaller than the leakage groove 85 fall into the draw box 83, thereby being separated again, and the liquid in the lower shell 4 directly enters the draw box 83 through the square tube 81, and the draw box 83 can be pulled out by pulling the handle in the draw box 83, and the parts and liquid in the draw box 83 are centralized for treatment.
