Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, in particular to an overflow glue removing device for PCB board glue coating. Background Art

[0002] PCB boards are providers of electrical connections for electronic components. The main advantage of using PCB boards is that they greatly reduce wiring and assembly errors, improve the level of automation and production labor rate. Gluing is one of the important steps in PCB production and processing.

[0003] Chinese patent application number 202221275142.5 discloses a gluing device for PCB production, including a workbench, wherein driving mechanisms are installed on both sides of the upper surface of the workbench, a moving mechanism is connected to the driving mechanism, a gluing mechanism is arranged below the moving mechanism, a brush mechanism is installed on the gluing mechanism, and a drying lamp is also installed on the brush mechanism. The utility model is convenient for disassembling and replacing glue discharge tubes and brush plates of different sizes, which is convenient for gluing PCB boards of different sizes and convenient for use by staff. When gluing the PCB board, the PCB board can be preheated in advance, which avoids the occurrence of colloid agglomeration when it is cooled, improves the gluing effect and is highly practical. However, there are still some shortcomings in the implementation of the patent. Although the patent can gluing PCB boards of different sizes, when different sizes of glue discharge tubes and brush plates need to be replaced for PCB boards of different sizes during use, it is necessary to produce glue discharge tubes and brush plates of various sizes and models, which increases the production cost and requires staff to frequently replace them, which is inconvenient for staff to use. At the same time, in the process of gluing the brush plate, glue is easily overflowed from the positions on the two sides of the PCB board, causing the glue to overflow to the two sides of the PCB board. The glue attached to the two sides of the PCB board is operated, which makes the PCB board inconvenient to install during subsequent use, resulting in the problem of poor quality of the PCB board after production.

[0025] A third motor 11 is fixedly connected to the top of the feed mounting tube 7. The third motor 11 is controlled by a PLC programming program and can be controlled to rotate forward and backward and at an angle. The output end of the third motor 11 is fixedly connected to a bidirectional threaded rod 12 rotatably connected to the feed mounting tube 7 through a coupling. The outer surface of the bidirectional threaded rod 12 is threadedly fitted with two transmission blocks 13. The bottom of the transmission block 13 is fixedly connected to a baffle 14 slidably connected to the feed mounting tube 7. The side of the transmission block 13 is fixedly connected to a scraper plate 15 through a connecting rod. The outer surface of the scraper plate 15 is fixedly connected to a storage box 16 through a connecting rod.

[0026] The PCB board to be coated with glue is placed on the fixed placement plate 10 for fixing, and then the bidirectional threaded rod 12 is driven to rotate by the third motor 11 according to the width of the PCB board. The bidirectional threaded rod 12 drives the two transmission blocks 13 to move away from and close to each other. At the same time, the two transmission blocks 13 drive the baffle plate 14 and the scraper plate 15 to move. When the two scraper plates 15 are driven to fit the two sides of the PCB board, the third motor 11 stops rotating and glue is supplied into the feed installation tube 7. At this time, the baffle plate 14 blocks the glue in the feed installation tube 7 to prevent the glue entering the feed installation tube 7 from entering the two sides of the glue brush roller 9. Then, the connecting frame 6 and the feed installation tube 7 are driven downward by the electric telescopic rod 5. At the same time, the glue brush roller 9 fits the surface of the PCB board. Then the second motor 8 drives the glue coating. The brush roller 9 rotates, and the glue-coating brush roller 9 applies glue to the surface of the PCB board. At the same time, the first motor 2 drives the transmission threaded rod 3 to rotate forward and reverse, and the transmission threaded rod 3 drives the transmission plate 4 to move back and forth left and right, thereby driving the feeding installation tube 7 to move back and forth left and right, so that the glue-coating brush roller 9 evenly applies glue to the surface of the PCB board. At the same time, during the gluing process, the scraper plates 15 on both sides of the feeding installation tube 7 scrape off the glue overflowing from both sides of the PCB board, and then enter the storage box 16 through the scraper plates 15 for storage, so that the gluing device can evenly apply glue to PCB boards of different widths, without the need to replace glue coating rollers of different sizes and types, thereby reducing production costs. At the same time, the glue overflowing from both sides of the PCB boards of different widths during the gluing process is automatically cleared and collected, thereby improving the quality of the PCB boards after production.

[0029] The glue in the glue liquid box 17 is pumped into the first connecting pipe 19 through the first pump body 18 and the pipeline, and then the first connecting pipe 19 pumps the glue into the first glue inlet pipe 20, and at the same time, the glue is pumped into the second glue inlet pipe 21 through the hose, and then the first glue inlet pipe 20 and the second glue inlet pipe 21 are used to supply glue to the glue-coating combing roller 9 in the feeding installation pipe 7, and at the same time, the second glue inlet pipe 21 is driven to move according to the width of the PCB board through the transmission block 13, so that the glue inlet pipe can accurately supply glue to the feeding installation pipe 7 according to the width of the PCB board, thereby improving the effect of automatic glue supply to the glue brush in the feeding installation pipe 7.
