With the rapid development of science and technology, various kinds of scientific and technological products are becoming more and more complex, and the processing is also becoming more precise and micro-finished. "Laser engraving" is the use of laser light to accurately and minutely engrave the surface of a board or circuit board to produce a specific Patterns, lines or numbers to meet the needs of the process or marking. Engraving work can be divided into single-sided engraving or double-sided engraving. If you want to automate double-sided engraving, you must machine the flipping action of a board (such as a circuit board).

At present, there are two main types of turning mechanisms for the machine: one is to clamp the device to one side of the circuit board, and then the mechanism is used to drive the clamping device to rotate to achieve the turning operation of the circuit board, but the disadvantages are: Since the board is usually a large-area sheet, it is only clamped to one side. During the turning process, the board is easily broken and causes serious damage. The other one is fixed around the circuit board by a fixture, for example, using a rigid frame, and then rotating the fixture with a mechanism to achieve the purpose of turning over. The advantage of this method is that the circuit board does not break, and the disadvantage is that the circuit board does not break. : After processing or finishing, the board must be placed in or removed from the frame by machine or manual, adding process, and because the frame is placed around the board, it is impossible to close the edge of the board. Engraving, which limits the engraving work.
