Flexible board touching and aligning device

The invention provides a flexible board touching and aligning device. The flexible board touching and aligning device comprises board touching rods, elastic board touching pieces and a sensor, whereina plurality of elastic board touching pieces are fixed on the board touching rods, the elastic board touching pieces feed back a alignment state of a printed circuit board by making contact with theprinted circuit board, the sensor sends out a control signal according to the alignment state fed back by the elastic board touching pieces, and the board touching rods move according to the control signal sent out by the sensor, when a product is placed on an object storage plate, the board touching rods get close to each other, the elastic board touching pieces make contact with the edge of theprinted circuit board and drives the printed circuit board to move to a preset position, and the elastic board touching pieces trigger the sensor to send out the control signal to control the board touching rods to get away fro
