Description

Technical Field

[0001] The invention relates to the technical field of automated processing of circuit boards, and in particular to a clamping and flipping device for circuit boards in automated processing. Background Art

[0002] A circuit board, also known as a circuit board, is an electrical component that makes circuits miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be divided into single-sided boards and double-sided boards. In the early days when the technology was immature, single-sided boards with more restrictions were usually used, while double-sided boards are more commonly used today. This type of circuit board has wiring on both sides, but to use the wires on both sides, there must be an appropriate circuit connection between the two sides. This "bridge" between circuits is called a guide hole. A guide hole is a small hole on the PCB that is filled or coated with metal, which can be connected to the wires on both sides. Because the area of ​​a double-sided board is twice that of a single-sided board, and because the wiring can be intertwined, it is more suitable for use in more complex circuits than single-sided boards.

[0003] In the process of double-sided board processing, usually both sides of the circuit board need to be wired. In the prior art, the traditional processing method is to manually flip the circuit board after one side is completed.
