Description

Technical Field

[0002] A flexible printed circuit board, also known as a "flexible board", is a printed circuit made of a flexible insulating substrate. The flexible circuit provides excellent electrical performance, can meet the design requirements of smaller and higher-density installations, and also helps to reduce the assembly process and enhance reliability. The flexible printed circuit board is the only solution to meet the miniaturization and mobility requirements of electronic products. It can be freely bent, wound, and folded, can withstand millions of dynamic bends without damaging the wires, can be arranged arbitrarily according to the spatial layout requirements, and can move and stretch arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection. The flexible printed circuit board can greatly reduce the volume and weight of electronic products, and is suitable for the development needs of electronic products towards high density, miniaturization, and high reliability. When processing a flexible printed circuit board, its surface needs to be inspected, so a surface detector for flexible printed circuit boards is required.

[0003] When operators perform inspection work on flexible printed circuit boards, they often use corresponding surface detectors for flexible printed circuit boards. Although existing instruments can achieve the purpose of detection, in actual use, manual clamping and fixing of flexible printed circuit boards are mostly required. This operation method increases the labor intensity of operators, and may further reduce the detection efficiency. Since the sizes of circuit boards are different and the fixing mechanisms mostly cannot be automatically adjusted, the practicability is reduced. Content of the Utility Model
