[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figures 1-5 As shown in the figure, an auxiliary device for PCB board welding processing according to one embodiment of the present invention includes a housing 1. A cover 2 is fixedly installed on the top of the housing 1 by screws. A filter purification assembly 3 is installed on the cover 2. The filter purification assembly 3 includes a mounting base 301 fixedly installed on the top of the cover 2 by screws. A bag cage 302 is fixed to the bottom of the mounting base 301. A through hole 303 is opened in the middle of the cover 2 for the bag cage 302 to pass through. A filter bag 304 is fitted on the surface of the bag cage 302. A honeycomb activated carbon column 305 is inserted and installed inside the bag cage 302. The top of the mounting base 301 is threadedly connected to a cover 306. A vent 307 is provided in the middle of the cover 306. A cleaning component 4 for cleaning the filter bag 304 is provided on the cover 2. A suction fan 5 is fixed to the top of the cover 2. A suction pipe 6 is fixed to the suction end of the suction fan 5. A suction hood 7 is installed at one end of the suction pipe 6. An exhaust pipe 8 is fixed to the exhaust end of the suction fan 5. One end of the exhaust pipe 8 passes through the cover 2 and extends into the interior of the housing 1. A dust exhaust pipe 9 is fixedly connected to the bottom of the housing 1. A valve 10 is installed at the bottom of the dust exhaust pipe 9. A U-shaped seat 11 is fitted and fixed on the surface of the housing 1.

[0024] When the PCB is welded, the device is placed beside, and then the air suction fan 5 is started, which can suck the smoke and dust generated during welding into the shell 1, and under the action of the filtering and purifying assembly 3, the smoke and dust can be filtered and purified. The specific filtering and purifying process is that after the smoke and dust enter the shell 1, they pass through the filter bag 304 and the honeycomb activated carbon column 305. The filter bag 304 can filter some particulate matters in the smoke and dust, and the honeycomb activated carbon column 305 can adsorb some harmful substances in the smoke and dust. Finally, the relatively clean gas is discharged from the air hole 307. Therefore, the harm to the health of the workers can be reduced. When the screen holes of the filter bag 304 are blocked and affect the filtering efficiency, the cleaning assembly 4 can be used to clean the filter bag 304. When a large amount of particulate matters accumulate in the shell 1, the valve 10 can be opened to discharge the particulate matters from the dust discharge pipe 9. When the honeycomb activated carbon column 305 is invalid, the cover body 306 can be unscrewed, the honeycomb activated carbon column 305 can be taken out from the bag cage 302, then a new honeycomb activated carbon column 305 is installed in the bag cage 302, and finally the cover body 306 is screwed on.

[0025] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , in some embodiments, the cleaning assembly 4 includes four connecting columns 401 fixed symmetrically at the bottom of the shell cover 2. The bottom of the four connecting columns 401 is fixed with a fixed ring 402. A tooth ring 403 is arranged between the fixed ring 402 and the shell cover 2. The tooth ring 403 is rotatably installed on the fixed ring 402. The bottom of the tooth ring 403 is fixed with two arc-shaped sliding blocks 408 symmetrically. The top of the fixed ring 402 is provided with an annular groove 409 matched with the arc-shaped sliding blocks 408, so that the tooth ring 403 can stably rotate on the fixed ring 402. The inner wall of the tooth ring 403 is fixed with two connecting strips 404 symmetrically. The side wall of the connecting strip 404 is fixed with a brush 405. The brush 405 is closely attached to the surface of the filter bag 304. The top of the shell cover 2 is fixed with a motor 406. The output shaft of the motor 406 penetrates the bottom of the shell cover 2 and is fixed with a gear 407. The gear 407 is engaged with the tooth ring 403. When the screen holes of the filter bag 304 are blocked and affect the filtering efficiency, the motor 406 can be started. The motor 406 can drive the gear 407 to rotate. The gear 407 can drive the tooth ring 403 to rotate. The tooth ring 403 can drive the two connecting strips 404 to make circular motion. The connecting strip 404 can drive the brush 405 on the surface thereof to make circular motion, so that the particulate matters adhered to the surface of the filter bag 304 can be cleaned

[0026] As shown in Figure 1 and Figure 3As shown, in some embodiments, the bottom end of the shell 1 is funnel-shaped, so as to facilitate the smooth falling of the particulate matter into the dust exhaust pipe 9, and the bottom of the U-shaped seat 11 is provided with anti-skid lines, which are not shown in the drawings, and the anti-skid lines can play a good anti-skid effect, so that the U-shaped seat 11 can be placed more stably.

[0027] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of the present application.
