Description

Technical Field

[0001] The utility model belongs to the technical field of flexible circuit board production equipment, in particular to a faulty portion cutting device for a flexible circuit board. Background Art

[0002] Flexible circuit boards are printed circuits made of flexible insulating substrates that can be bent, wound, and folded freely. Flexible circuit boards can greatly reduce the size and weight of electronic products. However, flexible circuit boards need to be tested after production. When a fault is detected in the flexible circuit board, the faulty part is cut off from the entire flexible circuit board through cutting equipment.

[0003] A Chinese patent application (or patent) with announcement number CN221338790U discloses a flexible circuit board cutting device, which relates to the field of flexible circuit board processing. In order to solve the problem that when cutting the existing flexible circuit board, the circuit board to be cut needs to be placed on a cutting mold, and the circuit board and the cutting mold surface are pressed and cut by a pressing structure to cut the circuit board into shape, but due to production needs, the cutting mold needs to be replaced frequently to change the cutting shape of the flexible circuit board, but the cutting mold is usually engaged with the surface of the processing table, which is inconvenient to replace it. It includes a base; it also includes: a placement groove, which is integrally formed in the middle of the upper end surface of the base, the cutting mold is provided in the middle of the upper end surface of the base, and the cutting mold is movably engaged with the inside of the placement groove, the upper end surface of the cutting mold is provided with a number of evenly arranged shape cutters, and the bottom of the base is integrally formed with a through hole, and the through hole is connected to the placement groove.

[0004] The aforementioned flexible circuit board cutting device is equipped with a cylinder, a movable plate, a slide bar, and a cutting die. During use, the cylinder pushes the movable plate to move on the slide bar, and the cutting die is also mounted on the movable plate for cutting the flexible circuit board. This results in a problem in which the flexible circuit board can only be cut as a whole, and the target flexible circuit board strips cannot be cut from the flexible circuit board. Furthermore, the cutting die is mounted on the flexible circuit board, and during use, the flexible circuit board needs to be placed on the cutting die. After production, the flexible circuit board is in the form of a strip and rolled onto a reel. During cutting, the device needs to pull the flexible circuit board strip from the reel and lay it on the cutting die. After cutting, it needs to be pulled and laid again. This slows down the cutting process and hinders production. To address this issue, we provide a device for cutting defective sections of flexible circuit boards to address the aforementioned issues.
