PCB quick plate-making machine with parallel structure

Abstract

The invention relates to a PCB quick plate-making machine with a parallel structure. The machine comprises a rack, a workbench, a moving platform, sliding blocks, synchronous belts and a motor, the workbench is arranged on a platform of the rack, and three synchronous belts are arranged; the three synchronous belts are respectively arranged on the rack through a belt wheel, the three synchronous belts are respectively connected with the motor, and the three synchronous belts are respectively perpendicular to the workbench; the three synchronous belts form a triangular structure distributed onthe rack, three sliding blocks are arranged, and the three sliding blocks are respectively and fixedly arranged on the three synchronous belts; each sliding block is fixedly arranged on one synchronous belt, the moving platform is connected with three sliding blocks through a connecting rod, and the connecting rod is respectively hinged to the three sliding blocks and the moving platform; the motor is connected with a PC machine, when the PC machine is in use, cutters are arranged on the moving platform, and a circuit board is placed on the workbench. The PCB quick plate-making machine with the parallel structure is adopted, the mechanical structure is simple, and the stiffness is high.

Description

technical field [0001] The invention relates to a plate-making machine, in particular to a PCB fast plate-making machine with a parallel structure. Background technique [0002] At present, the processing technology of circuit board (i.e. PCB) is mainly traditional technology, which is composed of three parts: drilling-chemical etching-milling and forming. Among them, the chemical etching process is relatively complicated and consists of dozens of processes. The production cycle usually takes three Up to seven days, although the corrosive liquid will seriously affect the environment during the etching process, this is currently the most widely used method for mass production. The PCB rapid plate-making process is actually a pure mechanical processing process of the PCB board, which consists of three parts: drilling-engraving-milling. After the drilling process, the copper film material on the surface of the circuit board is removed by an engraving knife to obtain the corresp...

Problems solved by technology

[0003] Existing PCB rapid plate-making equipment is generally transformed from an engraving machine. From a structural point of view, it belongs to the traditional tandem Cartesian coordinate machine tool or gantry structure machine tool. The panel (needs to be turned over for processing), there are often broken lines or inter-line connections when engraving lines, and the relative position error between the pad and the engraved line is relatively large, and human intervention is required in the later stage
