Or reduce the problem of scrapping and replenishment of FPC black-hole wire boards caused by rough process problems such as drilling, calendering, and cutting, and evaluate how to select materials to achieve the best results for customers' use of flexible circuit boards, pre-production Pretreatment is especially important. The thickness of the copper plate used on the traditional FPC is too thick to effectively transmit information, and it will increase the volume of the circuit board. In addition, the traditional FPC production process will produce indentations on the board surface, but it cannot effectively The indentation is processed, which seriously affects the appearance of the board surface. For this reason, we designed a new type of black hole production line surface indentation device, which solves the inconvenience of the traditional black hole production line surface indentation device.

FPC black hole line technology realization elements:

The purpose of this utility model is to provide a black hole production line surface indentation device to solve the existing technical defects and unachievable technical requirements.

In order to achieve the above purpose, the present invention provides the following technical solutions: a black hole production line surface creasing device, including a feeding roller, a calendering device, a cleaning device, a cutting device and an oven, the bottom of the feeding roller passes through a support rod and a fixed plate The fixed plate is provided with cutting equipment and a conveyor belt, the cutting equipment is fixedly connected with the fixed plate, one end of the conveyor belt is set inside the cutting equipment, the bottom of the conveyor belt is connected to the ground through a connecting rod, and the lower part of the conveyor belt is provided with an oven. The connecting rod is connected, the lower part of the oven is provided with a storage room, the left side of the feeding roller is provided with a calendering device, the feeding roller and the calendering device are connected by a copper plate, the lower part of the calendering device is provided with a cleaning device, and the calendering device is connected to the cleaning device through the copper plate Connected, the cleaning device and the cutting equipment are connected through a copper plate.

Preferably, the calendering device is provided with a high-temperature spray gun, a rolling roller, a pressure device, a pressure plate, a bearing plate and a spring. The pressure device is fixedly connected, the pressure plate is connected to the bearing plate through a copper plate, and a spring is arranged inside the bearing plate.

Preferably, the cutting device is provided with a pressure device, a drill and a cutter, a pair of parallel pressure devices are arranged on the top of the cutting device, and a drill and a cutter are arranged on the bottom of the pressure device, and the cutter passes through a thread. Removable connection with the pressure device.

Preferably, the cleaning device is provided with a rotating shaft and a cleaning solution, and the copper plate is slidingly connected with the sleeve on the rotating shaft.

Preferably, a heater is provided in the oven, and a through hole is provided at the bottom of the oven.

Compared with the prior art, the beneficial effects of this utility model are as follows:

1. Compared with the traditional black hole production line surface creasing device, the improved black hole production line surface creasing device is equipped with a high temperature spray gun and a pressure plate in the calendering device. The high temperature spray gun heats the copper plate to make the copper plate After the rolling roller, the rolling roller rolls the copper plate. When the copper plate is under the pressure plate, the pressure plate presses the copper plate to make the copper plate become thin. During the pressing process, the spring in the bearing plate presses against the copper plate. The impact generated serves as a buffer.

2. Compared with the traditional black hole production line surface creasing device, the improved black hole production line surface creasing device is equipped with a drill, a cutter and a sprayer in the cutting equipment, and the cutter faces the copper plate. For cutting, the drill drills the cut copper plate. When the drilled copper plate passes under the sprayer, the surface of the copper plate is wetted to remove the indentation on the surface of the copper plate.
