[0029] Referring to Figure 1 and Figures 8-9 In a preferred embodiment, the hole cleaning module 5 further comprises: Two guide rail supports 501, both of which are arranged on the left upper rack cover 4, and both of which are provided with movable bases; Two electric telescopic rods 506, both of which are arranged on the two guide rail supports 501, and the output ends of both of which are fixedly connected with one side of the outer wall of the two movable bases; A cleaning chamber 503 is arranged on the two movable base blocks 502.

An air purifier 514 is arranged at the input end of the air pump body 515.

[0033] Specifically, before the resin plug hole, the electric telescopic rod 506 drives the movable base block 502 to move, so that the cleaning chamber 503 is in contact with the upper left rack cover 4 (the gap between the cleaning chamber 503 and the upper left rack cover 4 is reduced, and the PCB cleaning part is exposed), and then the PCB passes through the cleaning chamber 503, in this process, the cleaning motor 509 and the air pump body 515 are operated, the cleaning motor 509 can drive the cleaning roller 510 and the viscous sleeve layer 511 to rotate, and because the viscous sleeve layer 511 is in contact with the surface of the PCB, the PCB can be cleaned, and after one cleaning, the PCB passes through the wind pipe 512, at this time, the air pump body 515 can suck the external air into the air purifier 514, and then the air is conveyed to the inside of the communication chamber, and then the air is conveyed to the inside of the wind pipe 512 through the conveying pipe 518, so as to be cleaned twice, and the blowing direction of the wind pipe 512 is deviated to the viscous sleeve layer 511, so as to avoid the secondary pollution of the dust to the cleaned part after blowing the dust, until the cleaning is completed. When replacing, the bidirectional push rod 505 is operated to move the connecting piece 504, the open-close plate frame 507, the mounting seat 508 and other structures, so that the cleaning roller 510 drives the viscous sleeve layer 511 to move out of the cleaning chamber 503, then the viscous sleeve layer 511 is disassembled, and is reset after a new viscous sleeve layer 511 is replaced; In a specific application scenario, the hole cleaning module 5 is suitable for the PCB resin hole cleaning link, that is, the hole cleaning module 5 can clean the surface of the PCB before resin hole is formed, so as to avoid the negative influence of dust on the resin hole and printing of the PCB, thereby further improving the processing quality of the PCB. When cleaning, the device uses the double cooperation of the viscous sleeve layer 511 and the air pipe 512 to clean, and the surface of the viscous sleeve layer 511 is cleaned again by airflow after being attached, so as to increase the cleaning effect of the device. When airflow is used, the airflow passes through the air purifier 514 first, so as to ensure that the cleaning airflow is clean air and avoid secondary pollution. It should be noted that, when in use, the bidirectional push rod 505, the connecting piece 504, the open-close plate frame 507 and other structures can move the cleaning roller 510 and the viscous sleeve layer 511 out of the cleaning chamber 503, so as to replace the viscous sleeve layer 511 on the cleaning roller 510, thereby increasing convenience.

[0034] Working principle: Before resin hole, the electric telescopic rod 506 drives the movable base block 502 to move, so that the cleaning chamber 503 contacts the left upper rack cover 4, and then the PCB passes through the cleaning chamber 503. In this process, the cleaning motor 509 and the air pump body 515 are operated. The cleaning motor 509 can drive the cleaning roller 510 and the viscous sleeve layer 511 to rotate. Since the viscous sleeve layer 511 contacts the surface of the PCB, it can be cleaned. After one cleaning, the PCB passes through the air pipe 512. At this time, the air pump body 515 can suck the external air into the air purifier 514, and then transport it to the air pipe 512, so as to clean it again. The blowing direction of the air pipe 512 is inclined to the viscous sleeve layer 511, so as to avoid secondary pollution of dust to the cleaned part after blowing dust. The cleaning is completed. When replacing, the bidirectional push rod 505 is operated to move the connecting piece 504, the open-close plate frame 507, the mounting seat 508 and other structures, so that the cleaning roller 510 drives the viscous sleeve layer 511 to move out of the cleaning chamber 503, then the viscous sleeve layer 511 is disassembled, and is reset after a new viscous sleeve layer 511 is replaced; In use, the heating element 311 is operated, the heating element 311 heats the heating rod 313, and at the same time, the air flow pump 304 is operated, so that the external air enters the air heating cavity 307 through the air inlet filter 309, and is heated by the heating rod 313 to control the resin in the stirring inner cavity 312 to maintain stable viscosity. When the resin is plugged, the delivery pump 303 is operated, the delivery pump 303 delivers the resin in the stirring inner cavity 312 to the defoaming inner tube 314, and at the same time, the air flow pump 304 delivers the air flow in the air heating cavity 307 to the outer sleeve tube 316 through the air heating tube 317, further maintaining the temperature of the resin in the defoaming inner tube 314, and at the same time, the electric push rod 324 is operated to adjust the distance between the movable support 322 and the fixed support 308 until it is adjusted to the appropriate position, at this time, the servo motor 323 is operated, the servo motor 323 drives one of the installation shaft rods 321 to rotate, and then drives one of the linkage wheels 319 to rotate, so as to cooperate with the linkage belt 320 to make the two installation shaft rods 321 and the extrusion frame 325 rotate synchronously, so as to further make the extrusion rollers 326 on both sides of the outer sleeve tube 316 rotate synchronously, and at the same time, the defoaming inner tube 314 is extruded, so as to force the bubbles in the defoaming inner tube 314 to break, thereby removing the bubbles in the resin, and then the resin is delivered out through the resin joint 302 to perform the resin plugging operation.
