[0002] With the rapid development of science and technology, among electrical components, the application of FPC (flexible printed circuit board) in high-tech products such as smart phones and smart computers has gradually increased. FPC is a highly reliable and extremely flexible printed circuit board. FPC has the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0003] In order to better utilize the internal space of the product and optimize the product structure, the FPC circuit board can be partially bent according to needs. However, due to its flexible characteristics, the bending action is hindered. Currently, most of the bending actions are performed manually. When the quantity is large, some semi-automatic equipment such as die pressing will be used for bending.

[0271] Inspection operation: After the flattening operation is completed, the control device controls the image acquisition device 91 to take pictures of the flattened material and detect the production error of the material, and at the same time transmits the detected error data to the control device so that the control device can select the corresponding bottom mold 1047 according to the error data.
