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 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.
The prior art has the following defects: 1. when conveying a polyimide film flexible circuit board product, firstly placing the polyimide film flexible circuit board on a flexible circuit board clamp bottom plate, and then connecting an upper cover plate of the flexible circuit board clamp with the flexible circuit board clamp bottom plate by using screws to complete the positioning of the polyimide film flexible circuit board; when the screws are used for screwing, a plurality of screws need to be fixed during each feeding, so that the feeding time is increased; meanwhile, the processed polyimide film flexible circuit board can be taken out only by sequentially dismounting the screws during blanking, so that the efficiency of feeding and blanking of the polyimide film flexible circuit board is reduced. 2. When the polyimide film flexible circuit board is cut, the polyimide film flexible circuit board product is conveyed to a cutting mechanism through a flexible circuit board positioning jig to be cut off, and then the polyimide film flexible circuit board product is moved by a moving mechanism; after the blanking and collecting device collects the broken materials of the flexible circuit board on the flexible circuit board positioning jig, the same flexible circuit board positioning jig is used for positioning and conveying the next polyimide film flexible circuit board product; when the blanking and collecting device collects the broken materials of the flexible circuit board on the flexible circuit board positioning jig, the blanking and collecting device occupies the only flexible circuit board positioning jig, and the polyimide film flexible circuit board product cannot be positioned and conveyed through the flexible circuit board positioning jig; the polyimide film flexible circuit board product cannot be processed when the blanking and collecting device works, and the cutting efficiency of the polyimide film flexible circuit board product is reduced. 3. When the polyimide film flexible circuit board is cut off, firstly, the polyimide film flexible circuit board clamp extends for a long distance, and then the cutting mechanism acts to cut off the extended polyimide film flexible circuit board; and the fixed spout in polyimide film flexible circuit board anchor clamps rear is less to polyimide film flexible circuit board anchor clamps extension portion supporting role when polyimide film flexible circuit board anchor clamps reach out for a long time, causes the slope of polyimide film flexible circuit board anchor clamps easily when shutdown mechanism and polyimide film flexible circuit board anchor clamps contact, influences the stability of polyimide film flexible circuit board anchor clamps at the cutting-off in-process. 4. When cutting off the redundant materials of the polyimide film 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 materials of the polyimide film flexible circuit board; the pushing power of the cutting cylinder under certain air pressure is certain, when the polyimide film 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 film flexible circuit board, so that the condition that the cutter is damaged due to the fact that the rigid contact force between the upper cutting knife and the lower cutting knife is larger after the upper cutting knife and the lower cutting knife cut off redundant materials of the polyimide film flexible circuit board with smaller thickness is caused, and the service life of the cutting mechanism is shortened.

The flexible circuit board cutting mechanism 33 solves the problem that when redundant materials of the polyimide film flexible circuit board are cut off, the cutting cylinder is directly used for pushing the cutter to reach a fixed position under certain air pressure so as to cut off the redundant materials of the polyimide film flexible circuit board; the cutting cylinder pushes down the power to be certain under certain air pressure, and the upper and lower cutting knives are in rigid contact; when the polyimide film flexible circuit board with smaller thickness is replaced, the driving force provided by the cutting cylinder is far greater than the driving force required by cutting the polyimide film flexible circuit board, so that the condition that the cutter is damaged by the larger rigid contact force between the upper and lower cutting knives after the upper and lower cutting knives cut off the redundant material of the polyimide film flexible circuit board with smaller thickness is caused, and the service life of the cutting mechanism is shortened. By providing a shut-off force adjustment assembly 333; when the polyimide film flexible circuit board with smaller thickness is replaced, the adjusting screw 335 is rotated to a set position, and the lower end face of the adjusting screw 335 slides up along the inner wall of the adjusting shell 336; the adjusting spring 337 extends, and the upper end of the adjusting spring 337 is always in contact with the lower end surface of the adjusting screw 335; at this time, the upper end of the upper cutter 3311 is pressed by the regulating spring 337 to be smaller and the pressing force corresponds to a cutting force required for the polyimide film flexible circuit board having a smaller thickness; therefore, when the polyimide film flexible circuit board with smaller thickness is cut, the cutting force between the upper cutting knife 3311 and the lower cutting knife 3323 is reduced, the situation that the rigid contact between the upper cutting knife 3311 and the lower cutting knife 3323 damages the cutting knife when the cutting force is larger is avoided, and the service life of the cutting mechanism is prolonged.
