Device for eliminating dust on cut board edge and preventing sparks

Abstract

The invention belongs to the technical field of circuit board manufacturing and machining and in particular to a device for eliminating dust on a cut board edge and preventing sparks. The device comprises a board holding table and an ion fan movably mounted on the board holding table. Slide rail seats are fixedly mounted on both ends of the upper surface of the board holding table. Fan mounting brackets are slidably mounted on the slide rail seats. The ion fan is installed between the two fan mounting brackets. When a board is cut, the dust on the cut board edge is eliminated, and the synchronization of the sparks with the operation of the device is prevented. The device mainly acts to remove static electricity to prevent dust and sparks during the lamination process after the board is cut, so as to avoid generating dust on the edge of the board with the static electricity after cutting and prevent the dust from entering the board to scratch the board surface and cause internal open-circuit and internal short-circuit hidden dangers and prevent the sparks from burning the board edge. The device achieves a purpose of eliminating the dust generated by the cutting the board and preventing sparks, removes static electricity, and is safe to operate and simple.

[0002] With the further improvement of printed circuit board manufacturing technology, the requirements for board appearance and board edge quality are getting higher and higher. At present, although many companies in the copper clad laminate industry have made comprehensive improvements in terms of equipment, technology and substrates, but The effect still cannot completely prevent dust from entering the board and sparks from the edge of the board burning to the edge of the board.

[0003] After the board is cut, there is dust on the edge of the board along with the static electricity, which will cause the board dust to enter the board, resulting in scratches on the board surface, causing hidden dangers of internal opening and shorting, and sparks burning the board edge. In order to better control the cutting of the board There is dust on the edge of the rear plate. With the generation of static electricity, the dust on the plate will enter the plate, resulting in scratches on the plate surface, causing internal opening, internal short hidden dangers, and sparks burning the edge of the plate. This invention proposes a method to eliminate the edge of the cut plate Dust spark prevention device
