Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a workpiece turning device for circuit board processing. Background Art

[0002] Circuit boards are conductive patterns made of printed circuits, printed components or a combination of the two according to a predetermined design. The conductive patterns that provide electrical connections between components on an insulating substrate are called printed circuits. In this way, the finished board of printed circuits or printed circuits is called a printed circuit board, also known as a printed board or printed circuit board. Circuit boards can be divided into the following categories according to their functions: single-sided circuit boards, double-sided circuit boards, multi-layer circuit boards, aluminum-based circuit boards, impedance circuit boards FPC flexible circuit boards, etc., and double-sided circuit boards need to be processed on both sides during processing.

[0003] Double-sided circuit boards need to be flipped during processing so that both sides can be processed. Most existing flipping methods manually flip the circuit boards, and additional operations on the fixing mechanism are required before and after flipping, which makes the work efficiency low. For this reason, we propose a workpiece flipping device for circuit board processing. Utility Model Content
