Technical Field

[0001] The present invention relates to the technical field of PCB circuit board transportation and transfer, and more specifically, to a rotary transportation device for PCB circuit board production and processing and a use method thereof. Background Art

[0002] PCB circuit board, also known as printed circuit board or printed circuit board, is an important electronic component, a support for electronic components, and a carrier for interconnecting electronic components. It has excellent properties such as high density, high reliability, and assemblability. It includes single-sided board, double-sided board and multi-layer board.

[0003] Different electronic components are installed on the PCB circuit board according to the electronic component assembly sequence. The installation speed of each electronic component on the circuit board is different. Therefore, it is necessary to temporarily store the circuit boards assembled by the faster electronic component assembly process through the circuit board relay rack after the faster electronic component assembly process and before the slower electronic component assembly process, so as to adjust the different speed electronic component assembly processes before and after. At present, factories generally use manual methods to place circuit boards on the circuit board relay rack one by one, which is very slow, consumes human resources, and increases the labor intensity of staff.

[0004] PCB circuit boards are classified into amplifier circuit boards, control circuit boards, power circuit boards, receiving circuit boards, transmitting circuit boards, etc. according to their functions. Different electronic components need to be installed on circuit boards with different functions.

Circuit boards with different inclination angles are difficult to transfer to a unified circuit board relay rack.
