Punching device

Abstract

The invention relates to the technical field of circuit board manufacturing, and provides a punching device. The punching device comprises a rack, a punching mechanism and at least two workbenches, wherein the rack is provided with a feeding position and a punching position; the punching mechanism is arranged above the punching position; the at least two workbenches are used for bearing core boards; and the at least two workbenches can circularly move between the feeding position and the punching position, so that the punching mechanism is used for punching the core boards on the workbenches moved to the punching position. According to the punching device, after the core boards are positioned to one of the workbenches, the workbench can be moved to the punching position firstly, then the core boards on the workbenches are directly punched through the punching mechanism, the positions of the core boards do not need to be adjusted before punching, the punching precision is high, the punching time of the punching device is shortened, the waiting time is shortened, and the punching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to a punching device. Background technique [0002] At present, in the production of circuit boards, core boards are often used to process multi-layer circuit boards. According to whether the thickness of the copper layers on both sides is equal, the core boards can be divided into symmetrical core boards (equal copper thickness on both sides) and asymmetrical core boards (both sides have equal copper thickness). The copper thickness varies), and the asymmetric core board is also called the yin and yang copper core board. [0003] OPE (Optical Punch Equipment, optical punching equipment) punching is an indispensable part of the multilayer circuit board processing process. Before multiple core boards are pressed into a multilayer circuit board, in order to prevent the If there are quality problems such as layer deviation and sliding board after the boards are sta...

Problems solved by technology

[0004] After receiving the core board, the traditional punching device grabs the target on the core board through the punching alignment camera, and adjusts the position of the core board so that the target is aligned with the theoretical position to complete the precise alignment, and finally punches down After finishing the punching, because the target on the core plate is often far from the theoretical position, the position of the core plate must be adjusted in a large range before each punching, resulting in longer punching time and lower punching efficiency
