[0074] The fixed base 301 is arranged on the top of the printing bin 13, and the fixed base 301 is provided with a resin tank 305, and the interior of the resin tank 305 is provided with a gas heating cavity 307 and a stirring inner cavity 312;
[0075] The supplement interface 306 is arranged on the resin tank 305, and the resin tank 305 is further provided with an air inlet filter 309.
[0076] In the application, the plug hole defoaming unit 3 further comprises:
[0077] The three heating elements 311 are arranged on the resin tank 305, and the three heating elements 311 are provided with heating rods 313, and the three heating rods 313 are located in the interior of the gas heating cavity 307;
[0078] The airflow pump 304 is arranged on the resin tank 305, and the input end of the airflow pump 304 is communicated with the interior of the gas heating cavity 307;
[0079] The delivery pump 303 is mounted on the resin tank 305, and its input end is connected to the interior of the stirring chamber 312.
[0080] In this invention, the plugging and defoaming unit 3 further includes:
[0081] Mounting bracket 310 is mounted on fixed base 301. Resin connector 302 is mounted on mounting bracket 310. Defoaming inner tube 314 is mounted on resin connector 302 and delivery pump 303.
[0082] The outer tube 316 is disposed on the resin joint 302 and the delivery pump 303. The defoaming inner tube 314 is located inside the outer tube 316. The outer tube 316 is provided with an exhaust port 315.
[0083] The gas heat pipe 317 is installed on the air pump 304, and the output end of the gas heat pipe 317 is connected to the inside of the outer jacket tube 316.
[0084] In this invention, the plugging and defoaming unit 3 further includes:
[0085] A fixed bracket 308 is provided on the top of the printing chamber 13. An electric push rod 324 is provided on the fixed bracket 308. A movable bracket 322 is provided at the output end of the electric push rod 324.
[0086] Four mounting shafts 321 are respectively mounted on the fixed bracket 308 and the movable bracket 322. Each of the four mounting shafts 321 is equipped with a linkage wheel 319, and the two linkage wheels 319 on the same side are equipped with the same linkage belt 320.
[0087] In this invention, the plugging and defoaming unit 3 further includes:
[0088] Four extrusion frames 325 are respectively mounted on four mounting shafts 321, and the four extrusion frames 325 are located on both sides of the outer jacket tube 316.
[0089] Multiple shaft members 318 are respectively disposed on four extrusion frames 325, and multiple extrusion rollers 326 are respectively disposed on multiple shaft members 318;
[0090] Two servo motors 323 are respectively mounted on a fixed bracket 308 and a movable bracket 322. The output shafts of the two servo motors 323 are connected to one end of two mounting shafts 321 respectively through couplings.
[0091] Specifically, during use, the heating element 311 operates and heats the heating rod 313. At the same time, the air pump 304 operates, allowing external air to enter the air-heating chamber 307 through the air intake filter 309 and heat the airflow through the heating rod 313, so as to control the resin inside the stirring chamber 312 to maintain a stable viscosity.
[0092] When the resin is plugged, the delivery pump 303 operates, delivering the resin inside the stirring chamber 312 to the defoaming inner tube 314. Simultaneously, the airflow pump 304 delivers the airflow from the gas-heating chamber 307 through the gas-heating pipe 317 to the outer jacket tube 316, further maintaining the resin temperature inside the defoaming inner tube 314. At the same time, the electric push rod 324 operates to adjust the distance between the movable support 322 and the fixed support 308 until a suitable position is reached. At this point, the servo motor 323 operates, driving one of the... The mounting shaft 321 rotates, which in turn drives one of the linkage wheels 319 to rotate. This, in conjunction with the linkage belt 320, causes the two mounting shafts 321 and the extrusion frame 325 to rotate synchronously. This further causes the extrusion frames 325 on both sides of the outer tube 316 to drive the extrusion rollers 326 to rotate synchronously, while simultaneously extruding the defoaming inner tube 314. This forces the resin bubbles inside the defoaming inner tube 314 to burst, thereby removing the bubbles present inside the resin. Then, the resin is delivered through the resin connector 302 to perform the resin plugging operation.
[0093] In specific application scenarios, the via plugging and defoaming unit 3 is suitable for the resin conveying process of PCB resin via plugging. That is, the via plugging and defoaming unit 3 can squeeze the air bubbles present inside the resin during the resin conveying process, so that the extrusion roller 326 and the extrusion frame 325 apply pressure to the outer tube 316 and the defoaming inner tube 314 to force the resin air bubbles inside the defoaming inner tube 314 to break, thereby removing the air bubbles present inside the resin. This avoids the influence of air bubbles when the resin enters through holes, blind holes or buried holes, thereby increasing the resin plugging quality of the device. In addition, during defoaming, the device can deliver hot air to the support of the outer tube 316 and the defoaming inner tube 314 to heat the resin inside the defoaming inner tube 314, thereby maintaining the fluidity of the resin during the defoaming process and further improving the defoaming treatment effect.
[0094] It should be noted that the resin tank 305 can also be heated by the heating rod 313 and the heating element 311 to control the resin to maintain a stable viscosity and facilitate the stirring of the resin.
[0095] Reference Figure 1 and Figures 8-9 In a preferred embodiment, the orifice cleaning module 5 further includes:
[0096] Two guide rail brackets 501 are mounted on the upper left frame cover 4, and each guide rail bracket 501 is equipped with a movable base block 502.
[0097] Two electric telescopic rods 506 are respectively mounted on two guide rail brackets 501, and the output ends of the two electric telescopic rods 506 are respectively fixedly connected to one side outer wall of two movable base blocks 502.
[0098] Cleaning chamber 503 is located on two movable base blocks 502.
[0099] In this invention, the hole-filling cleaning module 5 further includes:
[0100] A bidirectional push rod 505 is installed on the cleaning chamber 503. Both output ends of the bidirectional push rod 505 are provided with connectors 504. Both connectors 504 are provided with opening and closing plate frames 507. Both opening and closing plate frames 507 are provided with mounting bases 508.
[0101] Two cleaning motors 509 are respectively mounted on two mounting bases 508. The output shafts of the two cleaning motors 509 are connected to cleaning rollers 510 through couplings. Two adhesive sleeves 511 are respectively mounted on the two cleaning rollers 510.
[0102] In this invention, the hole-filling cleaning module 5 further includes:
[0103] Two conveying pipes 518 are installed on the cleaning chamber 503. Two air pipes 512 are installed at one end of the two conveying pipes 518 respectively. Multiple cleaning air holes 513 are opened on the two air pipes 512.
[0104] A connecting chamber 517 is located at the other end of the two conveying pipes 518.
[0105] In this invention, the hole-filling cleaning module 5 further includes:
[0106] A connecting pipe 516 is provided on the connecting chamber 517, and an air pump body 515 is provided at the input end of the connecting pipe 516.
[0107] Air purifier 514 is located at the input end of air pump body 515.
[0108] Specifically, before the resin plugs the holes, the electric telescopic rod 506 drives the movable base block 502 to move, so that the cleaning chamber 503 contacts the upper left frame cover 4 (reducing the gap between the cleaning chamber 503 and the upper left frame cover 4 to avoid exposing the PCB cleaning area). Then the PCB passes through the cleaning chamber 503. During this process, the cleaning motor 509 and the air pump body 515 operate. The cleaning motor 509 can drive the cleaning roller 510 and the adhesive sleeve 511 to rotate. Since the adhesive sleeve 511 contacts the PCB surface, it can clean it. After the first cleaning, the PCB will pass through the air duct 512. At this time, the air pump body 515 can draw outside air into the air purifier 514 and deliver it into the connecting chamber. Then it is delivered to the air duct 512 through the delivery pipe 518 for a second cleaning. The air duct 512 blows air one layer towards the adhesive sleeve 511 to avoid secondary contamination of the cleaned area after the dust is blown off, until the cleaning is completed.
[0109] During replacement, the bidirectional push rod 505 operates, and the bidirectional push rod 505 drives the connecting piece 504, the opening and closing plate frame 507, the mounting base 508 and other structures to move, so that the cleaning roller 510 drives the adhesive sleeve 511 out of the cleaning chamber 503. Then the adhesive sleeve 511 is disassembled and reset after a new adhesive sleeve 511 is replaced.
[0110] In specific application scenarios, the via cleaning module 5 is suitable for the PCB resin via cleaning process. That is, the via cleaning module 5 can clean the surface of the PCB before resin via filling, so as to avoid the negative impact of surface dust on the resin via filling and printing of the PCB, thereby further improving the PCB processing quality. During the cleaning process, the device uses the dual cooperation of adhesive sleeve 511 and air tube 512 for cleaning. After the adhesive sleeve 511 is applied and cleaned, the surface is cleaned a second time by airflow to increase the cleaning effect of the device. At the same time, when using airflow, the airflow first passes through the air purifier 514 to ensure that the cleaning airflow is clean air and avoid secondary pollution.
[0111] It should be noted that during use, the cleaning roller 510 and the adhesive sleeve 511 can be moved out of the cleaning chamber 503 through the bidirectional push rod 505, the connector 504 and the opening and closing plate frame 507, so as to facilitate the replacement of the adhesive sleeve 511 on the cleaning roller 510 and increase convenience.
[0112] Working principle:
[0113] Before the resin plugs the holes, the electric telescopic rod 506 drives the movable base block 502 to move, so that the cleaning chamber 503 contacts the upper left frame cover 4. Then the PCB passes through the cleaning chamber 503. During this process, the cleaning motor 509 and the air pump body 515 operate. The cleaning motor 509 can drive the cleaning roller 510 and the adhesive sleeve 511 to rotate. Since the adhesive sleeve 511 is in contact with the PCB surface, it can clean it. After the first cleaning, the PCB will pass through the air duct 512. At this time, the air pump body 515 can draw outside air into the air purifier 514 and deliver it into the connecting chamber. Then it is delivered to the air duct 512 through the delivery pipe 518 for a second cleaning. The air duct 512 blows air towards the adhesive sleeve 511 layer to avoid secondary pollution of the cleaned area after the dust is blown off, until the cleaning is completed.
[0114] During replacement, the bidirectional push rod 505 operates, and the bidirectional push rod 505 drives the connecting piece 504, the opening and closing plate frame 507, the mounting base 508 and other structures to move, so that the cleaning roller 510 drives the adhesive sleeve 511 out of the cleaning chamber 503. Then the adhesive sleeve 511 is disassembled and reset after a new adhesive sleeve 511 is replaced.
[0115] When in use, the heating element 311 operates and heats the heating rod 313. At the same time, the air pump 304 operates, allowing external air to enter the air-heating chamber 307 through the air intake filter 309 and heat the airflow through the heating rod 313 to control the resin inside the stirring chamber 312 to maintain a stable viscosity.
[0116] When the resin is plugged, the delivery pump 303 operates, delivering the resin inside the stirring chamber 312 to the defoaming inner tube 314. Simultaneously, the airflow pump 304 delivers the airflow from the gas-heating chamber 307 through the gas-heating pipe 317 to the outer jacket tube 316, further maintaining the resin temperature inside the defoaming inner tube 314. At the same time, the electric push rod 324 operates to adjust the distance between the movable support 322 and the fixed support 308 until a suitable position is reached. At this point, the servo motor 323 operates, driving one of the... The mounting shaft 321 rotates, which in turn drives one of the linkage wheels 319 to rotate. This, in conjunction with the linkage belt 320, causes the two mounting shafts 321 and the extrusion frame 325 to rotate synchronously. This, in turn, causes the extrusion frames 325 on both sides of the outer jacket tube 316 to drive the extrusion rollers 326 to rotate synchronously, while simultaneously extruding the defoaming inner tube 314. This forces the resin bubbles inside the defoaming inner tube 314 to burst, thereby removing the bubbles present inside the resin. The resin is then conveyed out through the resin connector 302 for resin plugging operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
