A special punching device for circuit pcb board

Abstract

The invention discloses a punching device special for a circuit PCB. The punching device comprises a rack composed of a base and a stand column and a punching mechanism arranged in the rack; a telescopic sliding groove is formed in the end face of the bottom of the punching mechanism, a transmission sliding cavity is formed in the portion, located above the telescopic sliding groove, of the punching mechanism, a locking sliding cavity extending upwards is formed in the portion, located at the right side of the top of the telescopic sliding groove, of the punching mechanism, and a top extending segment of the locking sliding cavity is located on the right side of the transmission sliding cavity; a guiding sliding groove is formed in the inner side wall of the telescopic sliding groove in a surrounding mode, a telescopic sliding block is connected into the telescopic sliding groove in a matched mode, a telescopic screw hole is formed in the end face of the top of the telescopic sliding block, and a telescopic screw extending upwards is connected into the telescopic screw hole in a matched mode; a convex sliding block is arranged in the guiding sliding groove, the side, adjacent to the telescopic sliding block, of the convex sliding block is fixedly connected with the telescopic sliding block, and a locking sliding groove is formed in the end face of the right side of the portion, located over the convex sliding block, of the telescopic sliding block. The punching device is simple in structure, convenient to operate and high in working efficiency and safety, and the machining quality is improved.

Description

technical field [0001] The invention relates to the technical field of PCB board processing, in particular to a special punching device for circuit PCB boards. Background technique [0002] With the continuous advancement of science and technology, the surface quality requirements of circuit board products are becoming more and more stringent. In order to meet the above-mentioned quality requirements of circuit board products, it is necessary to ensure that the surface of the circuit board is not scratched when the circuit board is drilled, and the conductive layer on the circuit surface is not damaged. The above Circuit board processing procedure, the circuit board is placed on the workbench and fixed by the fixture, and then the drill head is used to drill the circuit board placed on the workbench.

[0002] With the continuous advancement of science and technology, the surface quality requirements of circuit board products are becoming more and more stringent. In order to meet the above-mentioned quality requirements of circuit board products, it is necessary to ensure that the surface of the circuit board is not scratched when the circuit board is drilled, and the conductive layer on the circuit surface is not damaged. The above Circuit board processing procedure, the circuit board is placed on the workbench and fixed by the fixture, and then the drill head is used to drill the circuit board placed on the workbench. Because the surface material of the circuit board is relatively soft, the traditional fixed clamping equipment Without the buffer function, it is easy to cause damage to the circuit board, resulting in scratch marks on the surface of the circuit board and damage to the conductive layer structure on the surface of the circuit board, resulting in the lack of scrapped circuit boards. In addition, the traditional punching equipment does not have a locking function. Especially when it is used to cause equipment damage during moving and handling, it is easy to cause accidental injury to the operator due to the exposure of the drill bit when the hole is not drilled, and the safety is poor
