Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flexible circuit board processing, and particularly relates to a flexible circuit board punching device. BACKGROUND

[0002] Flexible circuit board is a printed circuit made of flexible insulating base material. Flexible circuit provides excellent electrical performance, can meet the design needs of smaller and higher density installation, also helps to reduce assembly process and enhance reliability, and greatly reduces the volume and weight of electronic products, meets the needs of the development of electronic products to high density, miniaturization and high reliability.

[0003] Punching process is a common step in flexible circuit board processing technology. In some processing scenarios, due to the layout needs or heat dissipation requirements of flexible circuit board, punching is needed in local area. In addition, in the processing technology of some precision devices on the flexible circuit board, punching is also needed, for example, some defective products in batch precision devices are marked and punched to remove, so that only qualified products are left on the FPC flexible circuit board, which is convenient for subsequent processing. The traditional punching method is to manually mark the center point or contour of the punching area to be punched; then the FPC flexible circuit board is fixed on a suitable clamp to ensure that it will not move or deform during punching, and a suitable punching tool is selected according to the diameter, depth and requirements of punching. For small diameter holes, a manual drilling machine or a punching die can be selected; for large diameter holes or holes with special shapes, other professional punching equipment may be needed, and the hand must be kept stable during punching to avoid shaking or deviation. However, since the FPC flexible circuit board is light and thin and has a certain elasticity, in the punching process, especially when high-precision batch punching is needed, the traditional punching method not only has very low efficiency, but also cannot ensure the punching precision, and is easy to cause processing failure due to shaking or moving of the FPC flexible circuit board during processing.
