Technical Field
[0001] The utility model relates to the technical field of FPC cutting moulds, in particular to an FPC cutting mould. Background Art
[0002] Flexible printed circuit board, abbreviated as FPC, is a kind of printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the base material. In the production process of FPC, when cutting FPC, it is necessary to use the die cutting knife located inside the punching type board splitter to cut the FPC board on the upper surface of the template by punching and cutting.
[0003] When using the current FPC cutting mold, the staff often finds that the FPC cut by the current cutting mold will remain on the lower mold after cutting. After the upper mold leaves, the staff needs to manually remove the FPC on the mold. Since the number of FPCs cut is large and the size is small and difficult to remove, the cutting efficiency is reduced. Utility Model Content

After cutting, the fragmented FPC falls into the storage basket through the through hole on the lower mold. The staff can slide the storage basket to take out the storage basket, and then pour the FPC out of the storage basket without picking them up one by one. After the upper template leaves, the shaft can be rotated to drive the connecting block to rotate, and then drive the knocking block to knock the upper mold to prevent part of the FPC from being stuck in the through slot and not falling off, thereby avoiding the problem that the FPC cut by the current cutting mold will remain on the lower mold after cutting is completed. After the upper mold leaves, the staff needs to manually take the FPC off the mold. Since the number of FPCs cut is large and the size is small and difficult to remove, the cutting efficiency is reduced.

After cutting, the fragmented FPC falls into the storage basket through the through hole on the lower mold. The staff can slide the storage basket to take out the storage basket, and then pour the FPC out of the storage basket without picking them up one by one. After the upper template leaves, the rotating shaft can be rotated to drive the connecting block to rotate, and then drive the knocking block to knock the upper mold to prevent part of the FPC from being stuck in the through slot and not falling off. The connecting block is rotated to make the knocking block away from the lower mold. At this time, the first spring is in a twisted state, and the connecting block is loosened. , the knocking block knocks the lower mold under the action of the first spring rebound force, and rotates the half gear. When the half gear meshes with the flat gear, it will drive the flat gear to rotate, so that the connecting block is away from the lower mold. When the smooth surface of the half gear contacts the flat gear, the connecting block is reset under the action of the first spring rebound force, so that the knocking block knocks the lower mold. This reciprocating process makes the knocking more effective, and the motor is started. The output shaft of the motor drives the half gear to rotate, making the operation more convenient, thereby avoiding the problem that the FPC cut by the current cutting mold will remain on the lower mold after cutting is completed. After the upper mold leaves, the staff needs to manually take off the FPC on the mold. Since the number of FPCs cut is large and the size is small and difficult to remove, the cutting efficiency is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

When the smooth surface of the half gear 58 contacts the flat gear 59, the connecting block 54 is reset under the action of the rebound force of the first spring 56, so that the knocking block 55 knocks the lower mold 3, and so on and so forth, so that the knocking is more effective, and the motor 57 is started, and the output shaft of the motor 57 drives the half gear 58 to rotate, so that the operation is more convenient, and the F Placing the PC in the placement groove 61 can make the position of the FPC more stable. The two placement grooves 61 make it convenient for the staff to remove the cut scraps. During the descent of the upper mold 4, the two limit blocks 64 will preferentially contact the FPC to limit the FPC. As the upper mold 4 continues to descend, the four second springs 66 will gradually shrink, so their rebound force will act on the limit blocks 64 to improve the limiting effect and make the cutting process of the FPC more precise. The rubber pad 65 can prevent the limit blocks 64 from being damaged by the rigid contact with the FPC.
