A device for positioning and clamping a board includes a plurality of clamping devices for clamping an edge portion of the board. Each clamping device includes positioning members for positioning the board with respect thereto, and a dragging device disposed between the clamping devices for dragging the board into contact with the positioning members. The dragging device is provided with a board clamping portion including a lower claw and an upper claw having rotating disks rotatably installed thereon for swivably clamping the board, and a reciprocating mechanism connected with the board clamping portion for reciprocating the board clamping portion. A board is first clamped by the dragging device and is dragged into contact with the positioning members of the clamping devices. The board is then pivoted and its attitude is straightened by further movement against the positioning members of the clamping devices, then the board is firmly clamped by the clamping devices and the clamping by the dragging device is released. Finally, the clamping devices are moved and a standard location is determined at a portion where the board traverses a sensor, thereby improving the space efficiency and avoiding lowering of positioning accuracy due to scattering of cutting chips.

DETAILED DESCRIPTION It is an object of the present invention to provide a positioning and clamping device for positioning a printed circuit board at a proper location.
It is another object of the present invention to provide a positioning and clamping device for a printed circuit board, having an improved space efficiency.
According to an aspect of the present invention, a positioning and clamping device for a printed circuit board includes a plurality of clamping means disposed along a side of the board for clamping an edge portion of the board and a dragging means disposed between the plurality of clamping means for dragging the board.
The clamping means is provided with positioning members, while the dragging means comprises a board clamping portion which pivotally clamps the board and a reciprocating means for reciprocating the board clamping portion.
The above and other objects, features and advantages of the invention will become readily apparent from the following detailed description thereof which is to be read in connection with the accompanying drawings.
