Technical Field

[0001] The utility model relates to the technical field of mainboard welding, and in particular to a smoke treatment device used for welding of an optical module mainboard. Background Art

[0002] Solder is an important industrial raw material for connecting electronic components in welding circuits. It is a solder with a low melting point, mainly referring to solder made of tin-based alloys. The fumes produced by solder contain toxic gases, which can easily cause harm to your health if inhaled.

[0003] At present, the way to deal with soldering fumes in factories is to directly use fans to blow away the fumes. However, after the fumes are blown away, they will still remain near the working area. At this time, the unpurified fumes will have an impact on the health of employees. Therefore, a fume treatment device for optical module motherboard welding is proposed to solve the above problem. Utility Model Content

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Embodiment 1, a smoke treatment device for welding an optical module mainboard, comprises a welding table 1, and a smoke extraction and purification structure is arranged at the bottom of the welding table 1.

[0023] The smoke purification structure includes a negative pressure box 2 fixedly installed at the bottom of the welding table 1, a three-way pipe 3 penetrating to the top of the welding table 1 is fixedly installed on the back of the negative pressure box 2, a metal frame 4 is fixedly installed inside the negative pressure box 2, the three-way pipe 3 is located at the top of the metal frame 4, two filter plates 5 located at the bottom of the metal frame 4 are movably installed inside the negative pressure box 2, a bellows 6 penetrating into the inside of the negative pressure box 2 is slidably installed at the bottom of the negative pressure box 2, a motor 7 is fixedly installed on the right side of the bellows 6, a transmission rod 8 penetrating into the inside of the bellows 6 is fixedly installed on the output end of the motor 7, two umbrella gears A9 are fixedly installed on the outside of the transmission rod 8, the bottoms of the two umbrella gears A9 are meshed with umbrella gears B10, and the bottoms of the two umbrella gears B10 are fixedly installed with fan blades 11.

[0024] When the optical module mainboard is welded, the motor 7 runs to drive the two umbrella-shaped gears A9 outside the transmission rod 8 to rotate, and then the two umbrella-shaped gears A9 respectively drive the two fan blades 11 to rotate through the two umbrella-shaped gears B10 meshing at the bottom thereof, thereby generating an airflow to be discharged to the bottom of the bellows 6. At this time, the interior of the negative pressure box 2 becomes a negative pressure state. The negative pressure box 2 in the negative pressure state can absorb the smoke generated by the soldering operation on the top of the welding table 1 through the three-way pipe 3. After the smoke enters the interior of the negative pressure box 2, it is filtered through the two filter plates 5. After the filtering is completed, it is discharged to the outside with the operation of the two fan blades 11.

[0025] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0026] Two air suction hoods 12 are fixedly installed on the top of the welding table 1, and two three-way pipes 3 are respectively fixedly installed on the backs of the two air suction hoods 12 and are connected to each other.

[0027] By installing two suction hoods 12 connected to the three-way pipe 3, the smoke extraction diameter of the three-way pipe 3 can be increased, thereby increasing the working efficiency of the device.

[0028] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 2, and its details are as follows:

[0029] A blocking net 14 is fixedly installed on the surfaces of the two hoods 12 . The installed blocking net 14 can intercept and protect the air inlet of the air suction hood 12 , thereby preventing foreign matter from entering the interior of the air suction hood 12 .

[0031] A plurality of T-rods 15 penetrating to the top of the bellows 6 are slidably mounted inside the bellows 6, and a spring 16 mounted on the outside of the plurality of T-rods 15 is fixedly mounted on the top of the bellows 6. The plurality of T-rods 15 are respectively located inside the two side walls of the bellows 6.

[0032] After the bellows 6 is inserted into the negative pressure box 2, multiple springs 16 push the multiple T rods 15 to rise, thereby squeezing the two filter plates 5 inside the negative pressure box 2 upward. The metal frame 4 can prevent the two filter plates 5 from moving upward, and the two filter plates 5 can be firmly confined inside the negative pressure box 2.

[0033] Embodiment 5, this embodiment is a further improvement on the basis of embodiment 4, and its details are as follows:

[0034] The front and rear ends of the negative pressure box 2 are fixedly installed with a clamping block 17, and the front and rear ends of the bellows 6 are rotatably installed with a hook frame 18 mounted on the outside of the clamping block 17. Rotating the two hook frames 18 to fit on the outside of the two clamping blocks 17 can restrict the bellows 6 to the inside of the negative pressure box 2. At this time, the connection between the clamping block 17 and the hook frame 18 can be more stably squeezed by multiple springs 16. The bellows 6 can be pushed upward by hand to retract the multiple springs 16, and the hook frame 18 can be rotated to detach from the outside of the clamping block 17.

[0035] Embodiment 6: This embodiment is a further improvement on the basis of embodiment 4, and its details are as follows:

The two fan blades 11 are supported by the installed support plate 19 to rotate inside the negative pressure box 2.

[0037] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
