When manufacturing copper-clad laminates, it is necessary to cut the copper foil to the same size as the substrate, and then stack the cut copper foil on the substrate through a conveying device, and then heat the copper foil It is integrated with the substrate to complete the processing of the copper clad laminate.

At present, the Chinese utility model whose authorized announcement number is CN201483556U and whose authorized announcement date is 2010.05.26 discloses a copper foil cutting machine, including a frame, a copper foil pressing mechanism and a copper foil cutting mechanism. The mechanism is composed of upper knife, lower cutting mechanism and lower knife upper cutting mechanism. The lower knife upper cutting mechanism includes fixed blade, upper cutting blade, upper cutting knife seat, adjustment track, roller, swing rod, tension spring, fixed seat, connecting rod, Eccentric wheel sleeve, eccentric wheel, bearing, rotating shaft and motor reducer, the upper cutting blade is installed on the upper cutting knife seat, and the middle part of the upper cutting knife seat is provided with a fixed slope-shaped section adjustment track, the inclined surface of the adjustment track and the fixed position The surface of the roller is in sliding contact, the lower part of the upper cutter seat is movably connected with one end of the swing rod, the lower end of the upper cutter seat is pre-tightened connected with the swing rod through a tension spring, the other end of the swing rod is rotationally connected with the fixed knife seat, and the middle part of the swing rod is connected with the The upper end of the rod is rotatably connected, the lower end of the connecting rod is fixedly connected through the eccentric wheel sleeve, the inner ring of the bearing is fixedly connected with the eccentric wheel, the eccentric wheel rotates with the rotating shaft, and the rotating shaft is fixedly connected with the output shaft of the motor reducer.

The above-mentioned copper foil cutting machine releases the copper foil through the copper foil unwinding mechanism during use. After the copper foil unwinding mechanism releases the required length of copper foil, the motor reducer drives the rotating shaft to rotate. During the rotation process, the eccentric wheel is driven to rotate, and the swing rod is driven to swing during the rotation of the eccentric wheel. During the swing process of the swing rod, the upper cutting blade is caused to move upwards to cut the copper foil. However, due to the copper foil cutting Both the upper knife and lower cutting mechanism and the lower knife upper cutting mechanism of the machine are exposed outside the copper foil pressing mechanism, which makes the copper foil easy to slip and roll up during the cutting process, resulting in uneven cutting of the copper foil.

Utility model content

The purpose of the utility model is to provide a copper foil cutting machine, which can limit the sliding and rolling of the copper foil in the process of cutting the copper foil, so as to achieve the purpose of improving the flatness of the copper foil cutting edge.

The above technical purpose of the utility model is achieved through the following technical solutions: a copper foil cutting machine, including a frame, a cutting mechanism arranged on the frame, the cutting mechanism includes a The lower knife seat on the frame, the lower cutter fixed on the lower knife seat, the upper knife seat fixed on the frame and above the lower knife seat, the upper knife seat fixed on the upper knife seat The upper cutter, the driving assembly arranged on the frame and used to drive the upper knife seat to press down, the upper knife seat is provided with a pressing assembly for pressing the copper foil on the lower knife seat, so The pressing assembly includes a connecting block fixed on the side wall of the upper knife seat, a pressing block that is slidably connected to the connecting block through a guide post and used to press the copper foil against the lower knife seat , the guide post is also provided with a pressing piece for limiting the disconnection of the guide post from the connecting block and providing a pressing force for the pressing block.

By adopting the above scheme, the lower knife seat is used for the installation of the lower cutter, the upper knife seat is used for the installation of the upper cutter, and the driving assembly is used to drive the upper knife seat to press down. During the process of pressing down the upper knife seat, the pressing block It will be in contact with the copper foil first, and the driving force provided by the pressing member will press the copper foil on the lower knife seat, and then as the upper knife seat continues to press down, the upper cutter will come into contact with the copper foil, and the copper foil will be cut. Cutting, due to the pressing effect of the pressing block, it is not easy for the copper foil to slip between the pressing block during the cutting process, or to roll over by itself, so as to improve the flatness of the cutting edge of the copper foil Purpose.

The utility model is further set as: the pressing member includes a nut threaded on one end of the guide post passing through the connecting block, sleeved on the guide post and located between the connecting block and the connecting block.
