Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fully automatic chamfering apparatus for external connection terminals of a multi-surface printed circuit board in which a large number of circuit patterns are arranged and formed on one board.

[0002]

[Prior art]

 Printed circuit boards are widely used today in computers and their peripherals. A large number of external connection terminals for connecting the internal circuit to external circuit elements and the like are provided on the periphery of the printed circuit board, and the periphery of the circuit board on which the external connection terminals are formed is fixed. The chamfering is performed at an angle so that insertion into a socket for mounting a circuit board can be performed easily and reliably. Many of the conventional chamfering machines for performing this chamfering are for straightening and chamfering the periphery of a circuit board, and for chamfering arc-shaped, diagonal-shape or indented connection terminals. In addition, the edge of the circuit board could not be chamfered in a stepwise manner.

[0003] Conventionally, the processing time is shortened by fully automating operations of picking up a circuit board to be processed, transporting the circuit board to a processing position, determining a position, and performing processing feed during chamfering processing. No chamfering machine was provided. Furthermore, in the conventional processing machine, when cutting the connection terminal portion of the circuit board, the bottom surface of the circuit board is used as a reference point. Since the method of holding the substrate was unstable, uniform processing was difficult due to the lifting of the connection terminal forming portion at the periphery to be chamfered.

[0004] In order to solve the drawbacks of the conventional chamfering machine, a new type of chamfering machine capable of chamfering an arc type, a diagonal type or a concave type, and a number of stages of connection terminals has been developed. However, the new chamfering machine processes a single circuit board with one circuit pattern formed on one board, and many circuit patterns are arranged and formed on one board. It was not possible to continuously chamfer the external connection terminals of the obtained multi-surface printed circuit board.

The printed circuit board (7) is stopped by the upper and lower surface holding mechanism (5).
The pair of cutting machines (62) are brought to the cutting position, and the printed circuit board (7) or its external connection terminal (71) is provided.
The above-described fully automatic chamfering apparatus is configured to perform chamfering. 2. The slide block (43, 43 ′).
Are formed with concave grooves (431, 431 '), and the distal ends of the positioning pins (471, 471') at the distal ends of the positioning arms (47, 47 ') are formed in a conical shape.
When the tips of the conical positioning fixing pins (471, 471 ') are fitted into the positioning holes (72) of the printed circuit board (7), the conical positioning fixing pins (471, 4').
The tip of 71 ′) is located at the positioning hole (7) of the printed circuit board (7).
2) Through the slide block (43, 43 ')
The printed circuit board (7) is configured to be accurately positioned and fixed regardless of its thickness, by entering the recessed groove (431, 431 ').
Fully automatic chamfering apparatus described in 1.
