Description

Technical Field

[0001] This utility model relates to the field of circuit board welding machine technology, and in particular to a circuit board welding machine with a fume adsorption structure. Background Technology

[0002] In electronic information experiments, circuit boards often need to be soldered. Soldering, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. The fumes generated by some circuit board soldering machines are adsorbed and filtered by activated carbon filter plates.

[0003] However, in the existing technology, most activated carbon filter plates on circuit board welding machines are fixed and installed by bolts. When replacing them, the bolts need to be removed, which is inefficient. Therefore, a circuit board welding machine with a flue gas adsorption structure is proposed. Utility Model Content

The sliding rod 142 drives the snap-fit ​​post 143 to move, so that the snap-fit ​​post 143 is disengaged from the snap-fit ​​hole and the return spring 145 is compressed. Then the sealing plate 8 is pulled out, which makes it convenient for the staff to quickly take out the activated carbon filter plate 9 for replacement without disassembling the bolts, thus improving the replacement efficiency.

[0037] To achieve the purpose of movement, the moving structure 5 includes a horizontal column 501 fixedly connected to one side of the fixed column 4. A first moving groove is formed at the bottom of the horizontal column 501, and a first threaded rod 502 is rotatably connected within the first moving groove. A first moving block 503 is threadedly connected to the first threaded rod 502 and slidably connected inside the first moving groove. A first servo motor 504 is fixedly connected to one side of the horizontal column 501, and the output shaft of the first servo motor 504 is fixedly connected to one end of the first threaded rod 502. The first servo motor 504 is electrically connected to the control panel 3. A moving column 505 is fixedly connected to the bottom of the first moving block 503, and a second moving groove is formed at the bottom of the moving column 505. A second threaded rod 506 is rotatably connected within the second moving groove, and a second moving block 507 is threadedly connected to the second threaded rod 506 and slidably connected inside the second moving groove. A second servo motor 508 is fixedly connected to one side of column 505. The output shaft of the second servo motor 508 is fixedly connected to one end of the second threaded rod 506. The second servo motor 508 is electrically connected to the control panel 3. A cylinder 509 is fixedly connected to the bottom of the second moving block 507. The piston end of the cylinder 509 is fixedly connected to the upper surface of the dust collection hood 11. The first servo motor 504 and the second servo motor 508 drive the first threaded rod 502 and the second threaded rod 506 to rotate, respectively. The first threaded rod 502 and the second threaded rod 506 drive the first moving block 503 and the second moving block 507 to move longitudinally and laterally, respectively. This causes the second moving block 507 to drive the dust collection hood 11 to move through the cylinder 509. The dust collection hood 11 drives the internal welding machine body 12 to move and weld the circuit board, so that the dust collection hood 11 always covers the welding position, improving the smoke absorption effect and reducing smoke leakage.

[0038] Working principle: The circuit board is placed on the soldering table 1. The first servo motor 504 and the second servo motor 508 are controlled by the control panel 3. The first servo motor 504 and the second servo motor 508 drive the first threaded rod 502 and the second threaded rod 506 to rotate, respectively. The first threaded rod 502 and the second threaded rod 506 drive the first moving block 503 and the second moving block 507 to move longitudinally and laterally, respectively. The second moving block 507 drives the dust collection hood 11 to move through the cylinder 509. The dust collection hood 11 drives the internal soldering machine body 12 to move and solder the circuit board, so that the dust collection hood 11 always covers the soldering position, improving the smoke absorption effect and reducing smoke leakage. Then the first exhaust fan 6 is started, and the smoke is conveyed through the dust collection hood 11 into the hose 10, and then through the hose 10 into the adsorption box 7. After being adsorbed and filtered by the activated carbon filter plate 9, it is conveyed by the first exhaust fan 6 into one side of the internal partition 15 of the purification box 2. Then the external purification liquid is conveyed by high pressure. The liquid pump delivers the liquid into the inlet / outlet pipe 16, then through the outlet pipe 16 into the water distribution pipe 17, and then atomizes and sprays it out from multiple atomizing nozzles 18, allowing the purified liquid to fully contact the flue gas for secondary purification. The purified flue gas passes through the bottom of the partition 15, and then is delivered out of the outlet pipe 20 by the second induced draft fan 19. At the same time, the liquid level sensor inside the purification box 2 monitors the waste liquid inside the purification box 2. When the waste liquid volume reaches the expected value, the electronic valve is opened by the control panel 3, allowing the waste liquid to be discharged from the drain pipe 21 for centralized treatment. When the activated carbon filter plate 9 needs to be replaced, the toggle handle 144 is turned, which moves the sliding rod 142, which in turn moves the locking post 143, causing the locking post 143 to disengage from the locking hole and compress the return spring 145. Then the sealing plate 8 is pulled out, allowing the staff to quickly remove the activated carbon filter plate 9 for replacement without removing the bolts, thus improving replacement efficiency.
