[0002] Flexible circuit boards, also known as soft circuit boards and flexible circuit boards, are highly favored for their excellent properties such as light weight, thin thickness, and free bending and folding. During the production process of flexible circuit boards, it is usually necessary to solder pads on the flexible circuit boards to connect with other circuit boards. When soldering pads on flexible circuit boards, it is usually necessary to fix the flexible circuit boards in a certain position before soldering the pads. Most of them are manually pressed and fixed. Manually pressing the flexible circuit board can easily cause a large number of wrinkles on the outer surface of the flexible circuit board due to pressing, which affects the quality of the flexible circuit board. Therefore, an anti-wrinkling device is needed to prevent wrinkles on its surface.
