Description

[0002] A circuit board, also known as a PCB circuit board, is a basic component used to support and connect electronic components. It is usually made of non-conductive materials and printed with conductive circuits and layout patterns of other electronic components. The circuit board is mainly used to provide electrical connections: various electronic components are connected together through the conductive circuits and pads on the circuit board, and current is transmitted through the metal foil on the circuit board or the copper wires between the electronic components.

[0003] During the production of existing circuit boards, it is necessary to grind the four sides of the circuit boards. However, when grinding the circuit boards, because various electronic components are installed on the front side of the circuit boards, only the back side of the circuit boards can be fixed for grinding. This grinding method is slow and only a single unit can be polished at a time. When the sides of the circuit boards are fixed for grinding, although multi-layer circuit boards can be stacked and polished, the electronic components on the circuit boards are likely to be damaged while the circuit boards are stacked.

[0004] Therefore, a circuit board polishing device is proposed. Utility Model Content

Because the vacuum suction pipe 4 is fixedly connected to the connecting pipe 5, and the connecting pipe 5 is fixedly connected to the multi-group diversion suction pipe 6, the vacuum pump 3 draws air from the multi-group diversion suction pipe 6 through the connecting pipe 5. Because one end of the diversion suction pipe 6 is rotatably connected to the lower end of the vacuum suction table 8, and the upper end of the vacuum suction table 8 is fixedly connected to multiple groups of vacuum suction cups 19, the vacuum pump 3 draws air through the vacuum suction cups 19. Before working, multiple groups of circuit boards 10 are placed on the surface of multiple groups of vacuum suction cups 19. Because the vacuum pump 3 draws air through the vacuum suction cups 19, a low pressure is generated inside the vacuum suction cups 19, so that the vacuum suction cups 19 are firmly adsorbed and connected to the circuit board 10, which is convenient for fixing the circuit board 10 and keeps the circuit board 10 relatively stable during grinding and rotation, which is conducive to the fast and stable grinding of the circuit board 10.

The output shaft of the second motor 23 passes through the second fixed plate 24 and is fixedly connected to the grinding disc 25.

[0029] During operation, after the circuit board 10 is fixed, the push rod motor 20 is started, and the output shaft of the push rod motor 20 drives the first fixed plate 21 to move inwardly, because the output shaft of the push rod motor 20 is fixedly connected to the first fixed plate 21, the first fixed plate 21 is fixedly connected to the two sets of fixed rods 22, the two sets of fixed rods 22 are fixedly connected to the second fixed plate 24, the second motor 23 is fixed inside the first fixed plate 21 and the second fixed plate 24, and the output shaft of the second motor 23 is fixedly connected to the grinding disc 25, so the push rod motor 20 drives the first fixed plate 21 to move inwardly. The grinding disc 25 moves. When the grinding disc 25 moves to the specified position, the push rod motor 20 is turned off and the second motor 23 is started. The output shaft of the second motor 23 drives the grinding disc 25 to rotate to grind both sides of the circuit board 10. When the grinding is completed, the push rod motor 20 is started again to drive the grinding disc 25 to move outward, and then the first motor 13 is started.
