In electronic products, different electronic components are usually connected by a flexible circuit board for power supply and communication. The electronic component is provided with a flexible circuit board electrically connected thereto, the flexible circuit board protruding outside the electronic component to connect an electrical connection portion of another component. The circuit can be bent at will, has light folding weight, small volume, good heat dissipation and convenient installation, breaks through the traditional interconnection technology and is widely applied. For the mobile phone, the space left for the battery core is not much due to the more and more compact space design inside the mobile phone, the connection between the battery core and the mobile phone main board needs to meet the requirement of shock resistance and is convenient to install, and therefore the flexible circuit board of the battery core needs to be bent and formed to meet the requirement of buckling the battery core and the mobile phone.
The existing bending forming equipment comprises a data compensation executing mechanism and a bending forming mechanism, wherein the data compensation executing mechanism is in transmission connection with the bending forming mechanism; the bending forming mechanism comprises a forming positioning carrying platform used for carrying the flexible circuit board, the forming positioning carrying platform is in transmission connection with the data compensation executing mechanism, and the position of the forming positioning carrying platform is adjusted through the data compensation executing mechanism and is used for adjusting the position of the flexible circuit board on the bending forming mechanism. The bending forming equipment ensures the yield of the bent flexible circuit board by adjusting the position of the forming and positioning carrying platform through the data compensation executing mechanism, the whole bending forming process is automatically carried out, manual operation is not needed, and the labor cost is reduced.

When the polyimide flexible circuit board is cut off, firstly, the polyimide flexible circuit board clamp extends for a long distance, and then the cutting mechanism acts to cut off the extended polyimide flexible circuit board; and the fixed spout in polyimide flexible circuit board anchor clamps rear is less to polyimide flexible circuit board anchor clamps extension supporting role when polyimide flexible circuit board anchor clamps reach out for a long time, causes the slope of polyimide flexible circuit board anchor clamps easily when shutdown mechanism and polyimide flexible circuit board anchor clamps contact, influences the stability of polyimide flexible circuit board anchor clamps at the cutting off in-process. 3. When cutting off the redundant material of the polyimide flexible circuit board, directly using a cutting cylinder to push a cutter to reach a fixed position under certain air pressure to cut off the redundant material of the polyimide flexible circuit board; the push-down power of the cutting cylinder under certain air pressure is certain, when the polyimide flexible circuit board with smaller thickness is replaced, the pushing force provided by the cutting cylinder is far greater than the pushing force required by cutting the polyimide flexible circuit board, so that the condition that the cutter is damaged by the larger rigid contact force between the upper cutting knife and the lower cutting knife after the upper cutting knife and the lower cutting knife cut off the redundant materials of the polyimide flexible circuit board with smaller thickness is caused, and the service life of the cutting mechanism is shortened.
