[0026] At the end of the conveying table of the S6 circuit board, the manipulator sucks the circuit board and transfers it to the board receiving and conveying table. The board receiving and conveying table transports the circuit board to the discharge end for the staff to pick up.

[0027] From the above technical solutions, it can be seen that the present invention has the following beneficial effects: For the two-in-one high-speed circuit board feeding machine and working method of the present invention, the entire equipment is divided into three parts: feeding, transporting and processing, and board receiving. The feeding uses a PPU structure manipulator, and the stacking height of the circuit board is sensed by a sensor, and a lifting device is used to control the elevation of the circuit board, so that the circuit board always maintains the same height during the feeding process, greatly improving the feeding efficiency. The circuit board limit posts and limit adjustment components are provided to ensure that the circuit board is centered, which is beneficial to subsequent processing work. The conveying table frame in the board receiving box can be adjusted to a suitable size according to the actual needs of production, with stronger adaptability and improved conveying efficiency.
