Description

Chamfering machine for chamfering the output terminal of the board {A CHAMFERING MACHINE FOR CHAMFERING OUTPUT TERMINAL IN THE BOARD}

The present invention relates to a chamfering machine for chamfering an output terminal in a substrate, the chamfering machine having a movable pneumatically adjustable inhaler and a side fixing and feeding machine. The movable pneumatically adjustable inhaler set sucks up the substrate and transfers it to the positioning sheet, and the side fixing and feeding machine secures one side of the substrate and feeds it stepwise into the supply opening of the pneumatically adjustable chamfering tool assembly. The chamfering machine can chamfer an output terminal or multiple lines of the substrate in the substrate.

Printed circuit boards today are widely applied to computers or peripheral devices. The edge of the printed circuit board has an output terminal of a logic circuit on the substrate, and the edge of the output terminal should be preferentially chamfered so as to be easily inserted into a connection port on a computer or other peripheral device. However, the conventional chamfering machine was able to chamfer only straight continuous terminals at the edge of the printed circuit board, and was not able to chamfer curved, inclined or interrupt output terminals or output terminals in the printed circuit board. Since the chamfer baseline of the conventional chamfering machine is set on the bottom of the printed circuit board, the chamfering depth on the edge of the output terminal may not be equal if the printed circuit board has an uneven thickness or warped surface. In addition, conventional chamfering machines cannot automatically operate the process of supplying, positioning, chamfering and discharging a printed circuit board. More manufacturing costs and time are required for the user to operate a conventional chamfering machine for chamfering the output terminals of the substrate. Thus, some improved output terminal chamfering machines have been improved to solve the above problem, and this kind of chamfering machine can chamfer curved, inclined or interrupted output terminals. However, such an improved chamfering machine cannot chamfer multiple terminals of an output terminal and a substrate in the substrate.

Therefore, the main object of the present invention is to chamfer an output terminal in a board, in particular having a side fixing and feeding mechanism and a pneumatically adjustable chamfering tool set, the side fixing and feeding mechanism being adapted to one side of the circuit board. And fixedly moved gradually into the opening of the pneumatically adjustable chamfering tool set for chamfering to provide a chamfering machine which can automatically chamfer an output terminal or multiple lines of the substrate in the substrate.

Another object of the present invention is to chamfer the output terminal in the substrate as described above, and has a side fixation with a rotating rod having two positioning arms that can move along a supply rail and can be rotated by a rotating cylinder. It is provided with a feeding mechanism, the tip of the two fixing pins to provide a chamfering machine that can be rotated to guide the substrate to a precise position and guide it into the fixing holes of the circuit board to firmly secure one side of the substrate. .
