[0018] Beneficial effects of the present invention:

[0019] The present invention provides a PCB circuit board production equipment with a polishing function. By providing a first motor, a polishing belt, an electric push rod and a clamping plate, the side polishing work of the copper-clad board during the lifting process of the copper-clad board can be realized, thereby improving the polishing efficiency of the copper-clad board. Meanwhile, only one set of motors is needed for the whole process, thereby effectively saving the polishing cost of the copper-clad board. Specifically, when the staff needs to polish the cut copper-clad board, the electric push rod and the first motor can be started at the same time. The electric push rod can drive the clamping plate to clamp and fix the copper-clad board on the conveyor belt, and then the first motor can drive the first threaded screw to rotate. During the rotation of the first threaded screw, the third threaded sleeve engaged on the outer wall thereof can drive the limit frame to perform lifting and lowering movement. Meanwhile, the limit frame and the electric push rod are fixedly connected by a connecting frame. Therefore, during the process of the limit frame rising with the third threaded sleeve, the copper-clad board can also be driven to rise as a whole.

[0020] At the same time, during the rotation of the first threaded screw, the driving gear can be driven to rotate, and the first driven gear can be driven to rotate through the driving gear, and the first driven gear can drive the first rotating column to rotate through the meshing between multiple groups of second driven gears, and during the rotation of the first rotating column, the first gear plate at the bottom can be driven to rotate, and during the rotation of the first gear plate, the second gear plate meshed with it can be driven to rotate, and the rotation of the second gear plate can drive the driving wheel to rotate, and during the rotation of the driving wheel, the polishing belt can be driven to rotate, so the polishing belt will continue to rotate during the lifting of the copper clad laminate, so that the side edge of the rising copper clad laminate can be quickly polished by the polishing belt, completing the polishing of both sides of the copper clad laminate;

[0021] During the rotation of the polishing belt, the cleaning roller arranged on one side of the polishing belt will contact it, and the bristles on the outer wall of the cleaning roller can quickly brush off the debris remaining on the polishing belt, so as to avoid clogging of the surface of the polishing belt and affecting its subsequent polishing work. At the same time, during the rotation of the first rotating column, the second bevel gear can also be driven to rotate. During the rotation of the second bevel gear, the first bevel gear meshed with it can be driven to rotate. The rotation of the first bevel gear can drive the second rotating column and the blades to rotate together, so that cold air is generated inside the box. The cold air generated in the box will be transported to the air outlet through the air duct. Since the air outlet is whistle-shaped, its air outlet is flat, so that the generated cold air can be concentrated and blown out from one side of the polishing belt, so that the polishing belt can be air-cooled when polishing the side of the copper-clad laminate, thereby effectively extending the service life of the entire polishing belt and avoiding overheating and burning of the side of the copper-clad laminate during polishing.

[0022] The present invention provides a PCB circuit board production equipment with a polishing function. Through the provided rotating roller, brush pad, sandpaper belt, second motor, third motor and fourth motor, the four sides of the copper clad plate can be quickly and evenly polished. At the same time, the polishing process can be carried out on the production line without the use of an additional workbench, thereby effectively improving the production efficiency of the entire PCB circuit board. Specifically, after the equipment completes polishing of the two sides of the copper clad plate, the copper clad plate rises to a certain position with the third threaded sleeve and stops. At this time, the second motor is started, and the second threaded screw can be driven to rotate by the second motor. During the rotation of the second threaded screw, the two groups of first threaded sleeves can drive the clamping frame below them to move to clamp and fix the copper clad plate. When the two sides of the copper clad plate after polishing are clamped and fixed, the electric push rod retracts to release the clamping plate of the copper clad plate. Then, the staff starts the third motor and the fourth motor at the same time. The fourth motor drives the rotating roller to rotate and polishes the other two sides of the copper clad plate through the sandpaper belt. The third motor can drive the third threaded screw to rotate and drive the fourth motor to move, thereby achieving complete polishing of the side of the copper clad plate and avoiding the generation of polishing dead angles.

The cold air generated in the box 24 will be transported to the air outlet 54 through the air guide pipe 29. The air outlet 54 is whistle-shaped, so its air outlet is flat, so that the generated cold air can be concentrated and blown out from one side of the polishing belt 13, and the polishing belt 13 can be used to cool the copper-clad board 3 when polishing the side edge, effectively extending the service life of the entire polishing belt 13, and also preventing the side edge of the copper-clad board 3 from overheating and burning during polishing.
