Description

Technical Field

[0001] This utility model relates to the field of nozzle cleaning technology, specifically a flushing type PCB spraying nozzle cleaning device. Background Technology

[0002] PCB coating is a key process in PCB manufacturing and post-processing. Automated equipment evenly coats the PCB surface or specific areas with functional coatings (such as protective varnish, insulating layers, and thermally conductive adhesives) to improve the circuit board's environmental adaptability, electrical performance, and mechanical reliability. This process is widely used in consumer electronics, automotive electronics, industrial control, aerospace, and other fields, and is one of the core processes ensuring the stable operation of PCBs under complex conditions. A flushing-type PCB coating nozzle cleaning device is used to clean PCB coating nozzles, prevent clogging, and ensure coating quality. Existing nozzle cleaning equipment typically uses a shoveling rod to unclog the nozzle, requiring manual cleaning each time, resulting in poor cleaning effectiveness and unsatisfactory performance.

The motor 29 is located on the top of the nozzle body 11, the drive rod 22 is fixedly connected to the end of the motor 29, the telescopic rod 221 is embedded inside the drive rod 22, the partition 23 is fixedly connected to the bottom of the telescopic rod 221, the cleaning plate 24 is located at the bottom of the partition 23, the transmission rail 26 is located on the top of the partition 23, the electric push rod 21 is located on the top of the nozzle body 11, the bracket 28 is fixedly connected to the bottom of the electric push rod 21, the transmission block 27 is located at the bottom of the bracket 28, and the limiting groove 25 is opened inside the nozzle body 11. Motor 29 is used to drive and control the rotation of cleaning plate 24 to clean the inside of nozzle body 11 and prevent material accumulation. Drive rod 22 is used to slide and connect telescopic rod 221. Partition plate 23 is used to form the inner groove of nozzle body 11. Transmission rail 26 is used to connect transmission block 27. Electric push rod 21 can control transmission block 27 to lift and move through bracket 28 to adjust the height of cleaning plate 24. Limiting groove 25 is used to limit and reinforce bracket 28. The cleaning plate 24 has a V-shaped structure, and the side of the cleaning plate 24 is tightly fitted with the inner groove wall of the nozzle body 11; The V-shaped cleaning plate 24 can fit tightly against the inner wall of the nozzle body 11, which can make the device more effective in preventing paint adhesion and clogging. The inner groove cross section of the transmission rail 26 has an inverted T-shaped structure, and the transmission block 27 and the transmission rail 26 are connected by a limiting rotation structure. With the limited rotational connection between the transmission block 27 and the transmission rail 26, the electric push rod 21 can control the partition 23 to move up and down to adjust the height of the cleaning plate 24. When not in use, it can be moved up and stored without affecting the spraying effect of the nozzle body 11. The inner grooves of telescopic rod 221 and drive rod 22 corresponding to telescopic rod 221 are both square column structures, and the drive rod 22 and telescopic rod 221 are limited sliding connection structures. The sliding connection structure between the telescopic rod 221 and the drive rod 22 facilitates the adjustment of the height of the cleaning plate 24 in conjunction with the electric push rod 21, and the square column structure allows the drive rod 22 to drive the telescopic rod 221 to rotate.

Drive rod 22 can drive partition 23 to rotate via telescopic rod 221. Cleaning plate 24 at the bottom of partition 23 rotates synchronously to clean the inside of nozzle body 11 and prevent paint accumulation from causing blockage. Under the limit rotation connection between transmission block 27 and transmission rail 26, limit groove 25 limits and guides bracket 28. Electric push rod 21 can control bracket 28 to drive partition 23 to move up and down. Cleaning plate 24 moves up and down synchronously to clean the inside of nozzle body 11 at various angles. This step automatically cleans up the residue, preventing blockages and improving performance.

Then the plug block 37 is separated from the plug groove 36. The cleaning plate 24 with a suitable angle can be selected according to the size of the nozzle 33 for installation and use. The bottom opening of the rotating block 32 fits into the nozzle 33, and the inner wall surface of the insertion groove 36 fits tightly into the surface of the insertion block 37. The rotating block 32 facilitates the control of the screw 35's rotation while also pushing out the accumulated material at the nozzle 33's opening. The rotating block 32 also plays an auxiliary role in cleaning. The tight fit allows the partition 23 to drive the cleaning plate 24 to rotate stably. Working principle: With the threaded engagement between the connector 34 and the connecting groove 31, rotating the nozzle 33 can separate the nozzle 33 from the spray head body 11.
